James Hansen: A “Fittest” to Remember

Posted on 05 July 2013 by Jerry

If you were a scientist, what would you do if you discovered your planet was following the fate of Venus whose water evaporated creating a runaway greenhouse effect that left a 900°F atmosphere of sulfur dioxide and sulfuric acid droplets?  What if your next forty years of research supported your fears and you knew that people on planet Earth had to make dramatic changes in order to survive?  What if decades passed and nothing was done?

You would be frustrated like Dr. James Hansen, now just retired, who headed the Goddard Institute for Space Studies for thirty-two years.  Dr. Hansen has continually warned the world of the impending disaster known as climate change.  Over many years he has spoken out in academic and scientific, governmental/congressional settings and the public press to transfer his knowledge to others.

Follow this link to the tape of James Hansen’s presentation at a 2012 TED conference.  Go to http://www.ted.com/speakers/james_hansen.html move to the right of the page and next to Dr. Hansen’s picture select “James Hansen: Why I must speak out about climate change”.  This exceptional presentation summarizes in a clear and straightforward way what Dr. Hansen knows about climate change.

Among many things he describes the changes he and his associates foresaw and forewarned about in 1981 that have all come to pass.  He elaborates on how CO2 allows heat energy to come to the planet from the sun and yet will not let it escape.  He explains the energy imbalance of the planet (more energy coming in than going out) that is gaining extra energy each day equivalent to 400,000 Hiroshima type bombs exploded 365 days per year. He concludes we must reduce our CO2 from today’s atmospheric 400 parts per million (see post of May 26, 2013 “Déjà Vu – 400PPM 2.2 Million Years Ago”) back to 350 parts per million to restore the planet’s proper energy balance.

In this month’s posting of Chapter 16 – Transcending Egocentricity from Beyond Animal, Ego and Time, we observe that evolution is forward looking and comment on the true meaning of “survival of the fittest”.  We suggest a completely different reading of the phrase based on the evolutionary process.  Further, the “fittest” are those people that “can demonstrate mastery in the present and future…who exhibit an ability to work with and lead others” and “have achieved the greatest level of consciousness and prescience by establishing future directions and taking actions that produce the greatest good for the greatest number.”

These “fittest” are the people we revere and remember.  Dr. James Hansen, will be one of those people.  Although he has much left to do, he should be listed with the other people who have dedicated their professional and personal lives to the betterment of the rest of us and all following generations.

Beyond Animal, Ego and Time: Chapters 14 & 15 – A Human Intervention Imperative and Enhancing the Life Experience

Posted on 05 June 2013 by Jerry

CHAPTER 14

 

A Human Intervention Imperative

 

We explored human uniqueness looking at physical attributes. We observed that advanced development of the prefrontal cortex in some mammals has been shown to be the probable source of self-recognition, empathy, and conscious decision-making. We argued language enables us to vicariously learn another’s knowledge without personal experience, contact, or observation. Finally, we described our ability to identify problems, absorb information, perceive consequences, conceive of options from which to choose, and make conscious decisions.

The fourth imperative is that we must decide to intervene in the course of events and influence or control their outcome. This is how we will assure life is protected from threat, evolution continues, and life experience is positive. Humanity is the key to completion of the evolutionary cycle and the emergence of the future living organism in which we will each participate. Only we can do what is necessary. We must consider the information presented, relate consequence to our personal lives, weigh our options and make a conscious decision to become guardians of life.

It is useful to pause and reflect on what has been presented. We must judge whether the information is credible and factual, if the assumptions and conclusions are logical and consistent. We must determine if the cosmology and resulting philosophy makes sense to a rational mind. We must decide if it is useful to society.

The five most obvious reasons to embrace the cosmology are:

  • It satisfies the genetic human “investigatory reflex”, identified by Pavlov, which drives us to seek a more comprehensive explanation of existence;
  • It resolves our cognitive dissonance by creating much greater consistency between our beliefs and our scientific knowledge;
  • The role of guardian of life is a singularly human responsibility which requires a shared philosophical point of view to insure a coordinated human response;
  • It directs human attention and effort to the most pressing problems of our time;
  • With sufficient time, evolution of a single future life form is possible, probable, or inevitable depending on whether you believe it is a natural evolutionary outcome or we will be effective in altering the future course of events.

Irrespective of which reason is most compelling to any individual, all we need do is decide to make a commitment and find the way to best implement our decision.

Human beings do not develop equally. We exist along a continuum of circumstance. Each of us has a specific set of advantages and/or disadvantages. Each is born with unique capabilities that can carry us only as far as our motivation and circumstances will allow. This means there are levels of consciousness some people are not capable of achieving and others, while capable, will be denied by circumstance. Those of us who are left, who are capable and enabled by circumstance, will achieve insights that vast numbers of human beings cannot and will not see. We will be lonely in our knowledge and yet have a responsibility to share what we know because global challenges require all of us to act.

Problems lasting a thousand years require generations of advocacy, intervention, and vigilance. Not only must we share insights with those around us, we must inform and educate subsequent generations. Evolutionary potential must be explained to those that follow. They must know that the role of guardian entails not only protecting life but also insuring its continued evolution and the enhancement of everyone’s life experience.

For most of us the time horizon in our lives has been limited. Seldom have we had to look forward by decades or centuries. With the survival issues we face and the imperatives we have identified, we are forced to lengthen our time horizon to include many future generations. This too points to our uniqueness within life. While it may not be accurate to say the rest of the animal kingdom is unaware of the passage of time, it is probable we are the only species capable of thinking about the future in terms of hundreds, thousands, or millions of years.

Looking back at the total human experience we see a history of continual and pervasive change. We began as hunter gathers, became farmers and entered the industrial and information ages. We have weathered countless variations of governance, experiencing anarchy, feudalism, theocracy, monarchy, oligarchy, dictatorships, and democracy. We have tried capitalism, communism, and socialism. Nothing about how we live is immutable or not subject to change. No options are closed to us. We have the freedom of a flexible response to future requirements.

We know change is inevitable and it begins with each of us. The first change required is the loss of our individual and collective political naiveté. We must stop relying on the politicians whom we have historically trusted to do what is right. If we have learned anything from the past and present it is that politicians are subject to persuasion from numerous sources most of which are motivated by their own gain and not by the greater good. This leads to political rationalization of suboptimal outcomes almost always favoring the few at the expense of the many.

Intervention is an active word. Nothing substantial will happen unless there is collective human action. Collective action is the product of personal commitment by many individuals. It is the determination of people to convince the people around him or her to act with them in a specific way. It is alignment of popular sentiment around issues whose time has come that establishes a political environment where progress can be made.

Each person must participate in the fight to protect life on our planet. At a minimum, each must pick the survival issue you care most strongly about or believe you can most affect and become an activist in that area. We must stop being mere onlookers and bystanders. It is not enough to go out and vote every few years without activism in between. It is not enough to watch a television program and nod to yourself about the issues. It is not enough to tell a friend you agree with them. Passivity convinces no one and is incapable of overcoming the inertia of the indecision of others.

Those who investigate issues, form opinions, and take a stand to change present reality determine future outcomes. Those who convince others rather than are convinced by others will make the difference in the future course. It is the people that join organizations, contribute time and money, attend rallies and conferences, write letters, and walk door to door in elections that create the future. These are the things we must do. When problems resolve, these are the people history will remember and honor.

Each of us must administer personal tests to determine how much is enough? How much time, money, and commitment are enough? Our answer is relative to our circumstances. The issue selected is about survival. It is important and must be reflected as such in one’s behavior. Important commitments are public. When everyone in your circle of influence knows your passion and position on an issue the commitment is declared. We each must expend the energy to move issues forward and incorporate them into our daily lives. They should be a major way we spend our spare time, a way to meet new people and to give our self a sense of accomplishment. When you know your contribution of time and money is forcing a choice between things you care about, you are reaching the level of commitment survival issues deserve.

As we attempt to move forward there will always be suggestions of short-term compromise from government and industry. Undoubtedly compromise will be imposed. Successful activists take the progress that is offered and demand more. Survival issues require dogged determination and sustained commitment. Progress is made with an uncompromising focus on the end outcome and a continuing sense of urgency to get there. We do not have to convince all or even half of the people to make a major change in direction. Supportive political environments are created with a smaller number. To effect change, however, we must reach a sufficient number of people. We will know we have made substantial progress when world leaders feature the survival issues and their world status in their annual reports to their citizens.

Jared Diamond in Guns, Germs & Steel, made a compelling argument that geographical and environmental factors bestowed advantages on people that were greater contributors to their success than racial or genetic differences.131 Just as he argued that the accident of origin was more responsible for success of peoples than their capabilities, we will see that through no fault of their own, the adversity of global climate change will fall on people who happen to be in the wrong place on the planet. There will be physical life crises that rival any in humanity’s past. We have to prepare for the inevitable upheavals and hardships of populations migrating to different territories to avoid the consequences of higher temperatures and shrinking fresh water resources. We must be prepared to help a humanity ravaged by change.

These and other challenges will undoubtedly involve new ways for us to live our lives. Those unwilling to give up the excesses of the past will resist these changes or who are afraid to move to new circumstances. But if the future mimics the past, change will predictably fall somewhere in the middle of our expectations, not as small or distant as we hope or as large or immediate as we fear. And as has been the case in the past, humanity will eventually invest the energy to adapt and weather the change in order to survive and continue to progress. The longer we wait, however, the larger the challenge becomes and the more energy we will have to invest.

We all long for life without cares surrounded by our loved ones where happiness and contentment are shared and each day is filled with optimism about a better future. However, the best we can hope for are days, weeks, months, or sometimes years of relative well being where effort made in the past shelters us from negative consequence in the present and future. This is the fundamental nature of life. It is not without hard work, planning ahead, being mindful of what is truly important and engaging in meaningful and rewarding relationships wherever we can find them. Even so we must anticipate and deal with future adversity.

Looking at our history and human nature, it is hard to avoid pessimism about the future. It is difficult to look at the threats to life just identified, human actions required, and necessary sacrifices and not be daunted by the enormity of the challenge. And yet, with all of this there is reason for optimism. Life is tenacious and insistent. Human beings have a history of weathering and overcoming adversity. We have always figured out a way. We will do no less in the future. We are embarked on an odyssey of change that is far from complete. Human history documents our relentless exodus from our roots in the animal kingdom. Figuratively, we struggle to complete our process of metamorphosis, standing up straight to finally transcend our animal origins. We must not underestimate the change that is possible or the strength of our desire and ability to accomplish it. We must intervene in the course of events and consciously become the guardians of life. We are the chrysalises that will become life’s butterfly.


 

CHAPTER 15

 

Enhancing the Life Experience

 

 

We have discussed the need for human beings to intervene in the course of events and assume responsibility for outcomes as guardians and custodians of life. In addition, we have dedicated four chapters to the Imperative of protecting life and identified survival issues we must resolve. Before we end our investigation we must briefly revisit the other two imperatives, to create an aggregate positive life experience and insure that evolution continues.

The imperative to create positive life experiences recognizes that our combined experience will be integral to the worldview of the future singular life form. We must assume that all contributions are not equal, that as the sensitivity of the sensory system and complexity of a creature’s intellectual ability increases, their relative contribution to future consciousness is magnified. This assumes the contribution of experience from higher life forms, i.e. human beings, is greater than that of lesser forms.

The life experience over which we have the greatest control is our own. This chapter is about how to apply this imperative to everyday life. Further insight on how we should live can be found by returning to Maslow’s Hierarchy of Needs. No one exists exclusively in self-actualization where we are only doing what we were “born to do” and continuously achieve at our full potential. Everyone spends time in multiple levels of the hierarchy each day. We have to breathe, eat and sleep, have shelter, and feel secure.

A key differentiator of one human life from another is the proportion of time spent satisfying physiological and safety needs versus higher-level belonging, esteem and self-actualization needs. Maslow’s hypothesis was we spend our lives seeking to invert his pyramid to achieve a state where the majority of our time is self-actualizing and time required to satisfy lower level deficit needs is minimal. It comes as no surprise that for most people the pyramid has not inverted and daily life is focused on the first four levels of the hierarchy. Nevertheless, humanity’s future global objective must be to minimize deficit needs and maximize the being need of Self Actualization.

Implicit in the Hierarchy of Needs is a time tense. As the individual conquers lower level survival needs, satisfying each successive level need requires a greater amount of time. As an example, those people who go beyond satisfying basic physiological needs for food, water, shelter, etc. find satisfying needs for love, acceptance, and belonging require a greater investment of time because they have to cultivate and nurture necessary relationships with others. Similarly, the Esteem needs of achievement, education, competence and respect all imply sustained effort over an even longer period of time. They also involve identification and definition of conscious goals and objectives.

This implied time tense prompts us to examine where our consciousness is focused, in the past, present moment, or future. Only the present moment is reality. Past moments are but memory. Future moments are but anticipation. While true that only the present moment is real, one of our strengths is our ability to think in all three time tenses; to learn from successes and failures in the past, to be fully conscious of circumstances and action required in the moment, and to identify what must be achieved in the future and channel present efforts accordingly.

There is benefit in the present to minimizing negative influences of the past. As an example, we can all remember negative comments and discouragement from others who told us we were not worthy or were not capable of achievement. These could have been the taunting comments of other children or discouragement from well meaning adults who sought to insulate us from an experience of failure. Unfortunately, we tend to give these memories too much influence on our present lives.

It is always true that past experiences occurred at a different place and time and to a different person, ourselves at an earlier moment. Our memories can be flawed by immaturity, inaccurate perception, and/or misinterpretation. The past must be reevaluated in light of the present. For this reason, we should be very harsh with memories, easily and quickly dismissing those inconsistent with who we now are, that do not contribute to our present and future success, and which do not support the direction we have chosen for ourselves. We should also retain memories that represent the best contribution to who we have become or are becoming.

At the same time we must give witness to the passing of the present moment for it is in each moment the history of our life is written. It is within each moment that we can fulfill our promise to be a good person, to do that which brings pride to those who know us and creates value in our existence. It is also the point at which experience takes place with lessons learned, insights gained, and memories made. We must extract all the value we can from each present moment, savoring the existence of that moment which comes but once for each of us.

Each moment presents us with a choice. We can exist, harvest, or invest in the moment. All living creatures exist in each moment but absent other thought or action mere existence offers the least value. When moments pass without notice the full potential of life is squandered. To harvest a moment is to recognize its passage and extract the fullness of its value. It can be to feel joy at being alive, the pleasure of the warm sunshine on your face or inhaling the fragrance of a flower. It can be laughter with a friend, hugging a child, or kissing your mate. It can be any thought or action that consciously puts you in your moment with full appreciation of its experience and opportunity.

To invest in the present moment is to expend effort focused on enhancing moments that follow. It can be working harder in the present to reduce effort or risk in the future. It can be crafting a solution today to forestall a problem anticipated tomorrow. It can be working to achieve a milestone that gives ongoing and sustainable advantage. Just as it is the bicycling energy of the moment to climb the hill that allows the opportunity to effortlessly coast down the other side, it is the excess returns on today’s invested effort put aside and saved that provides support to withstand adversity in the future. And when the individual creates value in excess of their own requirements, the surplus can be redirected to help others. Investment in the moment for the future is where the greatest value lies.

How we feel can be as important as what we do in the present moment. Not only are feelings a part of our memory and life experience but they also have a powerful influence over what we choose to do. Each of us has experienced days when we knew we had to do something we thoroughly disliked. We could spend the whole day procrastinating, dreading the task and postponing it to the last possible moment. On the other hand we have all also had days when we were looking forward to something we really enjoy. The rush to complete mundane tasks in order to be free to do something we look forward to makes for a very different day. How we feel during the two different days is very important. Knowing how to manage our daily mood can make a significant difference in the quality of our life experience.

While there are many benefits to living in the moment there are hazards as well. We have to recognize that being swept along in the emotion of the moment is one the risks that must be managed especially when the present emotion is negative. We are highly susceptible to our emotions but always have less concern when we are feeling positive.

Our objective must be to remain emotionally centered in a stable, secure, and positive state. Maintaining centered emotions requires frequent mid course correction much as the flight path of an airplane that is buffeted by the winds is continuously corrected to stay true to its destination. A good technique for re-centering your emotional state is contextual reformation. We will look at three techniques to help manage your emotional state to achieve the best life experience.

In the course of daily life we each live in a variety of contexts or interrelated conditions within which we exist. We move from one context to another as the activities of our day progress. For example, a married man with children may begin the day in a husband context when he wakes up in bed next to his wife. He moves to a father context when he sits down to breakfast with his children. As he goes to work he assumes his career context.

Throughout the day each of us moves from one context to another. It is easy to get lost in the daily contexts of our life and lose the centering that is critical to emotional stability and security. For example, when we encounter trouble on the job or difficulties in our marriage, we will tend to focus our attention on one context to the exclusion of all others.

On a more immediate level we can often find ourselves in a stressful or emotion filled situation where we are caught up in the moment and allow negative emotions such as fear, embarrassment or anger to control our reactions. This is an example of how we can lose control of the present moment and our centered emotional stability. It often occurs when we do something we regret.

A way of regaining control, our first technique, is to perform a process of remote projection. Briefly imagine going to a distant place, a corner of the room, where you can look back at yourself. Your objective is to see you in a broader, objective context. Look at your surroundings and situation. Imagine yourself moving farther and farther away. Reposition yourself in the broader context of the world around you. In the first case of one context dominating all other contexts, remote projection enables you to pull back and see all facets of your life and put them once again in proper perspective.

In the second example you are in the middle of a stressful situation and remote projection allows you to back out of an inward looking state and see your experience is transitory in nature. In both examples you can look at how you are reacting and ask yourself if the reaction is warranted. You should try to see yourself as others see you and ask if this is how you want to be perceived and known. If the answer is no, you can extract yourself from the context you are in or alter your reaction so you can be seen in a different way. This is how you can regain control of your situation and restore a centered state.

We all have times when we become discouraged, uncertain or apprehensive about something we are attempting to do. When our mood deteriorates we risk losing the motivation to keep pushing forward. Maintaining optimism is necessary to overcome normal human doubt. A second technique for contextual reformation and mood management is recollection. This technique involves recalling past accomplishments and remembering the positive emotions you felt when you achieved them. You could recall the pride and joy of your graduation from high school or college or the moment you learned you would be promoted. It is best to look back to anytime you achieved something that required significant effort and in some sense the outcome was in doubt.

Once you select an appropriate recollection, imagine yourself once more in that moment. Visualize your surroundings. Remember whom you were with and when and where the event happened. Recall the feelings you experienced and what caused them. This recollection enables you to feel the positive feelings of the past in the present. It reminds you that you can overcome challenges and prevail. It reinforces your ability to accomplish what you set your mind to do. It moves the emotional context of that moment to the present moment and re-centers your emotional state.

Our last technique for mood management is visualization. It helps create optimism about accomplishing something where the outcome may be in doubt. First you identify the major future goal, achievement, or event that you are working towards. Next you itemize the interim steps you need to take to accomplish your goal. Visualize yourself completing these things to get to the end outcome. Anticipate the perfect set of circumstances that would surround the outcome. Project yourself to the moment of successful completion. Imagine the emotions you will feel and the reactions of the people you care most about.

Visualization is a rehearsal for future success. It forces you to think about how you would accomplish your objective. It leads you to anticipate obstacles and conceive of ways to overcome them. Visualization renews the motivation that initially made you choose the goal you wanted to achieve. It increases your confidence in pursuit of it. No accomplishment is possible if you cannot at least imagine and visualize its attainment. The process of figuring it out increases your optimism of its feasibility and moves its reality from unthinkable and impossible to familiar and achievable.

The second area where you can have a direct affect on life experience is your impact on people around you. Your interaction with others and affect on them can often have a greater influence on positive life experience than managing your own moods. Evolution and natural selection have played a key role in shaping the behavior of genetically and biologically related family groups. There has been much study and documentation of interaction between family members with many theories of behavior from Freud and Jung to Watson and Skinner. For this reason our daily interaction with strangers is of more interest in this exploration.

It is important to consider two aspects of interaction with others. The first is that you must actively engage other people. Human beings are social animals who are susceptible to isolation, loneliness, and despair. We all too often move through our day interacting with others as if they are objects rather than people. Too often we relate to others in a perfunctory fashion, lacking real interest and responding in a highly superficial way. These interactions alienate and isolate both people by denying their value in each other’s eyes.

How often have we treated the person behind the counter as not deserving of recognition or worthy of validation? How do we react when people behind the counter treat us as if we are the nuisances? How many opportunities have we missed to break though the barrier of impersonality and actually engage one another? The tragedy is that a genuine personal connection and recognition of another’s existence and value takes only a few moments of attention and effort.

It means we have to pay attention to people and find a topic of conversation that establishes a common ground. We can chat about a shared characteristic, such as describing work you once did that was similar to their experience. It can be complementing them on a job well done. It can be any number of things that will demonstrate you are actually paying attention to them and thinking about their life or situation and acknowledging their existence. This leaves you and the other person with a positive feeling.

The second, and in many respects more important aspect of interaction with others is to actively seek opportunities where you can exhibit unanticipated kindness. While similar to active engagement, performing an unexpected kindness has a more powerful affect on the emotional context of others. It is an unsolicited offer to help someone you do not know and may never see again. The offered act must represent giving up something that is of value to you in time, effort or money. While the kindness benefits the other person, it benefits you as well in that it makes you feel good about yourself. It reinforces your kindness and care for other people. Opportunities for unanticipated kindness are often less obvious and always require more effort.

Actively engaging other people and performing unanticipated acts of kindness are like throwing pebbles into a pond. The beneficial effects will ripple out in ever widening circles affecting progressively more and more people. If what you do makes another person feel valued or that the world is a kinder place than they had thought, it improves their life experience that day. Further, it leads them to similar positive behavior that benefits someone else. Imagine the effect if everyone committed an unanticipated act of kindness each day. Imagine the power of over six billion daily acts of kindness.

When we think about the human condition it is not hard to imagine the cumulative effect of these kinds of actions. All human beings will react similarly when we reach out to them. Our DNA is 99.9% the same from one person to another regardless of ethnicity or nationality.132 Maslow’s hierarchy explains that the challenges we face in living day-to-day are the same. We must believe that the aspirations all people have for the quality of their life experience is similar.

Before we leave the subject of how we increase the quality of the aggregate life experience we must discuss the second largest contributing group, the rest of the animal kingdom. We are not the only contributors to the aggregate life experience. Plants and animals also contribute. Setting aside the assumed small contribution of plants, it is well documented that animals experience many emotions, are aware of pain and suffering, and have memory.

We must recall that at least four species other than Homo sapiens have demonstrated self-recognition.  These are the great apes (other than gorillas), Asian elephants, bottlenose dolphins and the Corvid bird family including magpies, crows and ravens. Anyone who has ever owned a pet or farm animal has seen a range of emotions in their animal’s eyes such as love, fear, happiness, or contentment. All who have read about animal behavior know about the nurturing and protection of the young by their parents.

The normal animal cycle of life consists of birth, growth, foraging and hunting, procreation, caring for offspring, aging and dying. While the life of wild animals can include difficult times like migrations, disease, avoidance of predators and starvation, it is possible to imagine that on most days there is a positive contribution to the aggregate life experience. This has been true even through the human development of an agrarian society. Small farmers and ranchers have always had a direct and personal interest in the welfare of their livestock if only as an investment they want to protect.

Most human beings in direct and personal contact with animals feel empathy and treat them with kindness. Pets elicit the stronger emotions of love and loyalty from their owners. Even people who are not pet owners, farmers, or ranchers generally react with concern when they encounter an animal that is suffering and in pain. These are normal human reactions and represent some of the higher states of emotion.

Human reactions change when we depersonalize our relationships with the animal kingdom. Our actions change when we are remote and no longer see or experience the reality of animal existence. We can avoid normal human reactions when animal care is unseen and the responsibility of others. Such is the case when we confine animals to artificial and limited enclosures in zoos, subject them to experimentation in medical laboratories, and turn them into commodities to be managed by big industrial food processors on factory farms.

Setting aside the negative examples of zoo confinement and medical experimentation that are both regrettable, the epitome of our present remoteness with the greatest negative effect is our relationship with the billions of animals in our food chain. The case in point is the treatment of animals under the control of big industrial food processors, the managers of our food supply, who raise and slaughter billions of animals each year in our name.

There is a sizable body of law pertaining to farm animal cruelty. Using the United States as an example, the nation has passed laws requiring humane treatment of livestock immediately prior to and during slaughter.133 In addition, about half the states enacted statutes that also set standards for the slaughter of animals. These statutes were designed to prevent needless animal suffering. They include description of how animals unable to move will be handled. For example they first must be stunned to unconsciousness before they can be dragged anywhere. The law also identifies the four means to be used to render animals unconscious before the actual slaughter which generally consists of slitting the animal’s throat and draining the body of blood. The four ways to render farm animals unconscious are with carbon dioxide administered in a chamber, captive bolt stunners which produce a forceful strike on the forehead, mechanical gunshot, and use of electrical current.135

Counting just cattle, chickens, ducks, hogs, sheep and lambs, and turkeys it is estimated we slaughtered over 4.8 billion animals in the U.S. in 2008. There are no government estimates for the slaughter of other farm animals, such as rabbits and horses.136 There are numerous video segments accessible on the internet that depict farm animal slaughter where humane steps to minimize pain and suffering have not been taken. With the huge number of animals slaughtered each year and the obvious terror, pain, and suffering experienced when they are not rendered unconscious, it is clear the existing law was a necessary first step to protect the life experience of these creatures.

With all the focus on the death of the animals it is surprising there are no national statutes and very few state laws that regulate the handling and living conditions of those same animals prior to slaughter. It is in this area where human beings have failed the animals managed in their name. We have allowed large agribusinesses to open high production factory farms that use business practices that destroy any opportunity for a positive life experience for the animals in their charge. These factory farms treat their animals as commodities with no concern for their quality of life. In fact, with the existing laws when enforced and followed, we are treating the animals more humanely as we put them to death than they have been treated in life.

Examples of their common practices include:

  • Confining eight to ten egg laying hens for the duration of their lives in indoor wire cages, called battery cages, measuring no more than sixteen inches wide and 67 to 86 inches long, about the size of an average filing cabinet drawer. These cages are so small the hens do not have room to fully spread their wings. These cages are in rows and stacked several levels high in windowless buildings that contain up to 100,000 birds.
  • Debeaking chickens, turkeys and ducks by cutting through bone, cartilage and soft tissue with a blade to remove the top half and bottom third of their beaks. This is done to reduce excessive feather pecking and cannibalism seen in stressed, overcrowded birds confined in factory farms.
  • Forced molting where egg producers starve their hens for ten to fourteen days forcing them to lose 25% or more of their body weight in body fat, feathers, liver tissue, musculature, and skeleton. This is done to reduce the cost of feeding the hens and produce eggs more cheaply.
  • Producing Foie Gras where birds are force-fed enormous quantities of food three times a day via a pipe inserted in their esophagus. This leads to enlargement of the liver and sometimes causes a rupturing of internal organs leading to infection and a painful death. This process normally lasts four weeks until the birds are slaughtered.
  • Producing “White Veal” where dairy farmers take unwanted male calves in the first 16-18 weeks of life and confine them in two foot wide crates where they are formula fed an iron and fiber deficient diet that results in anemia. The lack of movement and anemia retards muscle development that results in pale, tender meat.
  • Confining breeding pigs for their nearly four-month pregnancies in “gestation cages” which are two feet wide and seven feet long concrete floored metal cages. Once they give birth and their piglets are weaned they are quickly re-impregnated. On average these breeding pigs spend a total of ten months a year in these cages. This cycle is repeated for three to five years until the sows’ bodies have deteriorated to the point it is no longer profitable to breed them, at which point they are sent to slaughter.

These animal cages and crates severely limit animal mobility. Intensively confined animals are denied the ability to exercise, fully extend their limbs, or simply turn their bodies. They cannot perform integral, instinctual, and natural behaviors. For example birds cannot respond to their basic nesting instincts. Cages with wire flooring deprive them of the opportunity to express normal foraging, scratching and dust-bathing behaviors. They also prohibit hens from perching and roosting and do not allow comfort behaviors, such as stretching and wing flapping.

It is not possible to imagine a world where people do not consume or need to consume animal protein in their diet. While we cannot envision a world of strict vegetarians, we can imagine one where each person significantly reduces their animal protein consumption. Nevertheless we have an imperative to increase positive life experience. The life experience of a significant portion of the animal kingdom has been allowed to deteriorate to an unspeakable and unacceptable level of sustained cruelty. We must end the torture of these poor, defenseless living beings.

There has been a small, dedicated group of advocates who have made steady progress in this fight to end farm animal abuse and give all animals a chance to have positive life experiences. These compassionate people have succeeded in passing the laws regulating the slaughter of animals. In addition they have made progress in a handful of states that have passed laws that variously eliminate veal crates, gestation and battery cages, and the production of Foie Gras.

A forward-looking piece of legislation was the Prevention of Farm Animal Cruelty Act passed in California in 2008. This law was to “prohibit the confinement of farm animals in a manner that does not allow them to turn around freely, lie down, stand up, and fully extend their limbs.”137 It specifically protected all covered animals which meant “any pig during pregnancy, calf raised for veal, or egg-laying hen who is kept on a farm.” It passed in what can only be considered a resounding victory carrying a 63% majority.

The rest of us must join this small band of advocates to build the political will to extend this protection to farm animals everywhere. We must demand tougher penalties for violating animal cruelty laws. We must fund more pervasive monitoring of animal welfare to insure these standards are fully enforced. Finally, we must raise our children to understand the importance of creating a positive life experience for all living creatures. We must help them develop the empathy that will guide them to fight animal cruelty in all of its forms.

The fight against animal cruelty is as much about us as it is about the animals. Treating animals with the respect and care in life that they deserve is a significant way we can fulfill our responsibilities. Cruelty to another living creature is an example of the worst possible human behavior and is unworthy of the human species. As guardians of life and beneficiaries of the aggregate life experience, we must fulfill the imperative to enhance all life experience.

Beyond Animal, Ego and Time: Chapters 10 & 11 – Protect Life Imperatives – Ozone Hole and Climate Change

Posted on 10 April 2013 by Jerry

This posting continues the serialization of my book on this website.  As an incentive to readers to return to the site, each month I will post at least one Chapter of the book until the entire book is posted.  Scroll back over the last few months to read earlier “Beyond Animal, Ego and Time” chapters.  The book provides context for the blog, clearly explaining the underlying philosophy and identifying critical issues of our time. In the book Chapter 10 begins four chapters which identify the four threats to life that we have created.  This installment contains Chapters 10 & 11.

CHAPTER 10

Protect Life Imperative — Ozone hole

 

No species in history has been more successful than humans in imposing order on its environment. Human beings have organized and exploited the assets of our planet to serve our existence. We have built the physical infrastructure of cities, factories, and transportation and communication networks. We have harnessed sources of energy by mining the planet’s resources, damming the world’s rivers and splitting the atom. We have created industries to feed and nourish us through agriculture. In addition, we have established social, financial and governmental institutions to manage our interactions with each other. We have done these things and much more largely in the name of what we call progress.

For most of our existence our individual and collective impact on our planet was insignificant. We were few in number, the planet’s resources were plentiful and the ecology was resilient. Eras of plenty led to an inevitable expansion of our population to a point at which our impact went from inconsequential to consequential. The twentieth century was a tipping point when human capability became potentially catastrophic. Our actions and inventions became so powerful and global that we are able to threaten the existence of life itself. In some cases the growing threat posed by our actions was not obvious, in others it was.

We have had near misses that were the result of inadvertent action as opposed to conscious decisions. Tim Flannery in his book, The Weather Makers, while discussing the present issue of global climate change, describes the earlier threats faced in understanding the effects of chlorofluorocarbons (CFCs) which destroy ozone in the atmosphere.69 A CFC is an organic compound containing chlorine, carbon, and fluorine. It is produced as a derivative of methane and ethane. A related subclass is the hydrochlorofluorocarbons, which also contain hydrogen and are typically marketed by DuPont as Freon. Also of concern is bromofluorocarbon compounds known as halons.

Flannery, an Australian professor and climate change activist at Macquarie University, relates how in the 1920s Gordon Dobson, an Oxford University lecturer in Meteorology, and his collaborator F. A. Lindeman, a professor of experimental philosophy also at Oxford, recognized the importance of ozone in the atmosphere and began measuring it as a matter of scientific curiosity.70 Ozone in the upper atmosphere prevents dangerous ultraviolet light from reaching the Earth’s surface. Ultraviolet light’s most familiar affect is sunburn. Prolonged exposure is linked to the development of skin cancers. In two successive measurements of ozone concentrations in the stratosphere above the Antarctic in 1975 and 1995 ozone levels fell from historic levels measured at 320 Dobson units in 1955. Ozone above the Antarctic fell to 280 units in 1975 and 90 units in 1995. A Dobson unit is an arbitrary measure of the density of atmospheric ozone in a column of air over a specific point on the planet under a standard temperature and pressure. This dramatic reduction in ozone over the Antarctic was in contrast to very stable levels of ozone measured on the rest of the planet during the same period.

Obviously something serious was taking place in the stratosphere over the Antarctic. We now know our collective use of chlorofluorocarbons had created a hole or an area of significant reduction in the concentration of ozone above the South Pole. In 1995, Paul Crutzen, F. Sherwood Rowland, and Mario Molina were awarded a Nobel Prize for their pioneering contributions to explaining how ozone is formed and decomposes through chemical processes in the atmosphere.71 According to the Royal Swedish Academy of Sciences in awarding the prize to Paul Crutzen in 1970 he “showed that the nitrogen oxides NO and NO2 react catalytically (without themselves being consumed) with ozone, thus accelerating the rate of reduction of the ozone content.” Further, “The next leap in our knowledge of ozone chemistry was in 1974, when Mario Molina and Sherwood Rowland published their widely noted Nature article on the threat to the ozone layer from chlorofluorocarbon (CFC) gases – “Freons” – used in spray bottles, as the cooling medium in refrigerators and elsewhere and plastic foams.”

Flannery describes how close we came to making a fatal choice out of ignorance. Ozone, a particular form of oxygen, was discovered in laboratories in the early 1800’s. The oxygen we need for life consists of two oxygen atoms bonded together. Ozone consists of a three-oxygen atom molecule, which is created in the stratosphere through the interaction of the ultraviolet (UV) radiation of sunlight and oxygen. Because it can block more ultraviolet radiation than the two oxygen atom molecule, it keeps 95% of UV radiation (at wavelengths shorter than 0.4 microns) from the sun from reaching the surface of Earth. As a result of ozone’s instability, it is continuously losing its third atom degrading to normal oxygen while sunlight replenishes it by creating new three atom molecules. This process is normally in balance to maintain a reasonably consistent level of ozone in the stratosphere.

Chlorofluorocarbons, CFC’s, invented by industrial chemists in 1928, were used in the making of Styrofoam, as propellants in spray cans and for refrigeration and air conditioning. Their failure to react with other chemicals and resulting chemical stability at the surface of the planet always made them thought to be environmentally safe. Released into the atmosphere, however, they make their way to higher elevations in the atmosphere where they break down when subjected to ultraviolet radiation and release their chlorine atom. Chlorine atoms are very destructive to ozone, each atom of which can destroy 100,000 ozone molecules. Their destructive capacity goes up in colder temperatures which is why the ozone hole was found in the stratosphere over the South Pole which at minus 80˚ Fahrenheit is far colder than the minus 44˚ Fahrenheit found in the stratosphere at the North Pole.

The world clearly decided to do something about the problem caused by CFCs by signing the Vienna Convention for the Protection of the Ozone Layer in 1985 and the Montreal Protocol on Substances that Deplete the Ozone Layer in 1987. Fortunately they were not facing the hopeless situation we would have had if industrial chemists of the 1920’s had constructed their fluorocarbons with bromine rather than chlorine.

Tim Flannery states, “Although bromine lasts just one year in the stratosphere as compared with chlorine’s five, bromine is forty-five times more effective in destroying ozone than chlorine, and so swiftly would it have torn asunder those precious ten parts per million of ozone, that Earth’s sunscreen would have been destroyed even before F. Sherwood Rowland made his Nobel-winning discovery of the CFC threat to the ozone layer.”

Flannery continued, “Just how close the world came to such a fate can be seen in the uses to which industrial chemists had already put bromine. In the 1980’s, bromotrifluoromethane and bromochlorodifluoromethane – their trade names Halon-1301 and Halon-1211 respectively – came into widespread use in fire-suppression systems, particularly in art galleries and museums, where using water might cause damage. Because these chemicals are ten times as potent in destroying ozone as CFCs, they were banned under the Montreal Protocol … .”72

There are a number of conclusions to be drawn from this discussion of depletion of the ozone. The first conclusion, while not wanting to take anything away from the seriousness of the effects of chlorofluorocarbons (CFCs), is that life serendipitously benefited from early industrial chemists’ selection of chlorine as the more cost effective and less reactive chemical when compared to bromine. This choice of chlorine gave us an ozone deterioration we had an opportunity to perceive and attempt to address rather than a catastrophe we were too late to avoid.

Aristotle defined a tragedy as “The change to bad fortune which he (the character) undergoes not due to any moral defect or flaw, but a mistake of some kind.” Ozone depletion would have made for a classic tragedy if human beings had destroyed life in the pursuit of air conditioning and hair spray. We must also observe even the smallest effects from minor day-to-day activities multiplied by our number can now have global impacts far beyond our localized actions. We will bear an increasing responsibility to accurately assess the potential effects of our actions. We cannot afford to rely on serendipity to save us from unintended consequence or catastrophe.

It appears that collectively the world has acted swiftly enough to avoid the worst possible outcomes of ozone depletion. The Montreal Protocol of 1987, as amended in 1990, banned the most dangerous gases from 1996 forward. There was no instant fix however. Quoting again from The Royal Swedish Academy of Sciences, “Since it takes some time for the ozone-destroying gases to reach the ozone layer we must expect the depletion, not only over Antarctica but also over parts of the Northern Hemisphere, to worsen for some years to come. Given compliance with the prohibitions, the ozone layer should gradually begin to heal after the turn of the century. Yet it will take at least 100 years before it has fully recovered.”

At least a century for full recovery provides a graphic measure of the damage. And that assumes that we follow through on our healing endeavors. In naming our species, the word “sapiens” was selected. A derivative of the word sapience, it connotes wisdom and sagacity or keen and farsighted penetration and judgment. Our history indicates that as in the case of ozone depletion or other worldwide phenomena, we will seldom have perfect timing in coming to the realization of a problem and initiating the appropriate actions. We will always err. We will always realize and act too soon or too late. We must pose the question with grave issues like ozone depletion, if we are to err, do we want to err on the side of being too early or too late? Given the risks associated with being too late, the answer should be obvious that we need to be too early.

As is always the case, for at least a decade after Messieurs Crutzen, Rowland, and Molina published their findings, there was active political and public relations resistance from the chemical producer companies, of which DuPont was the largest stakeholder, to suggestions of banning the offending chemicals. The argument consisted of inconclusive scientific evidence of a connection between CFCs and ozone destruction and of serious economic loss that would come from seeking substitutes.

As usual, this industry resistance led to political inaction and almost a decade and a half passed before twenty countries decided to sign the Vienna Convention for the Protection of the Ozone Layer in 1985, which was largely a symbolic act. While the Vienna Convention brought a measure of legitimacy to the issue, it fell well short of specifying meaningful action to be taken. The signatories essentially agreed to meet and confer, share information, conduct their own research and promised to try to make further progress on the issue.

Countries did not commit to tangible action until signing the 1987 Montreal Protocol that became effective in 1989. In 1990 participating countries committed to phase out the offending chemicals and in 1992 they accelerated the phase out schedule. This represents a twenty-year lag between initial identification of the ozone problem and tangible action to solve it.

Further complicating our progress on replenishment of the ozone however, is a provision of the Montreal Protocol that was necessary to secure agreement and support from developing countries. This provision allows developing countries like China and India to continue using the offending CFC refrigerant HCFC-22 (hydrochlorofluorocarbon-22) through the year 2040. A further agreement in 2007 however, accelerated these requirements by specifying elimination of 97.5% of HCFC-22 in developing nations by 2030.  This chemical was eliminated from production in the European Union in 2004 and in the United States in 2010. Its use is mushrooming, however, in the developing countries with large populations such as China and India that are experiencing significant economic growth.

A news report stated, “The latest estimate from technical experts is that the chemical’s output in developing countries is rising 20 to 35 percent each year and could continue at that pace for years. Slightly over 2 percent of Indian households currently have air conditioners, according the LG Electronics of South Korea, a giant maker of air conditioners. In China, ownership soared to 87.2 air conditioners per 100 urban households in September (2007), from 24.4 seven years earlier. The countryside, home to two-thirds of the nation’s population, is poised for even greater growth. In 2005, there were 6.4 air conditioners per 100 rural households, a 35-fold increase from a decade earlier.”73

This report coincided with a re-expansion of the size of the Ozone Hole in 2006 to a level matching its record size achieved in 2001. This unanticipated record use of these dangerous chemicals in the developing world has surely lengthened our 100-year ozone problem. While the problem continues, we are once again put at risk by the failure of the world’s leaders to act. It may be we are losing ground on ozone depletion rather than making progress. Only time will tell if the ozone hole over the Antarctic begins to widen once more or depletion of ozone over the Arctic, where a new hole appears periodically, becomes problematic or whether ozone density is reduced as a result of the anticipated global climate change.

This highlights the difficulty faced in fixing the ozone layer and demonstrates the inertia encountered when issues of major impact are left to scientists, industries, politicians, and governments. The scientists inevitably have insufficient power to propel the issues forward. Politicians are successfully lobbied by industries with their bottomless resources and support that keeps politicians in office. Industries are motivated by protecting the status quo and the continued growth of earnings. Governments of the developed nations, which created the problem, are lobbied by developing nations to postpone corrective action until after their development. What is typically missing is the citizenry who ultimately has the political muscle to move governments to overrule industries. Absent the world citizenry, life could die waiting for action.

This then is another observation to be drawn from our experience with the ozone issue. People must be knowledgeable and must be involved if humanity is to react in a timely way to issues that threaten our existence. We must err on the side of early action to give ourselves the benefit of as much time as possible to enact a remedy. We must demand our governments act, recognizing we can make amends for economic dislocations which we cause and which we can reverse if the future contradicts our present view.

 

CHAPTER 11

Protect Life Imperative — Climate Change 

The prolonged threat of the ozone hole leads us to the present issue of global climate change. Climate change is not as simple as the ozone hole because it has no ozone hole. There is not just one phenomenon with obvious chemical causes where incidental human behavior is a major contributor. Everything about global climate change is complex, diffuse, and central to post industrial society. It is complex because it requires understanding of the planet’s atmospheric, oceanic, and weather systems. It is diffuse because every human being in the developed world contributes greenhouse gases to the environment. It is central to society because dependence on carbon based energy sources, coal, oil and natural gas, and agricultural processes are essential to our modern civilization. In developing countries carbon based energy sources, deforestation and agriculture are viewed as critical to catching up with the developed world.

Issues of global climate change began in the early 19th century with investigation of the causes of the ice ages.74 Joseph Fourier in 1829 hypothesized atmospheric gases would permit the sun’s radiation to penetrate to the surface of the planet but would keep heat from escaping upward. In 1859, John Tyndall, a natural philosopher, conducted experiments that identified multiple gases including water vapor and carbon dioxide that trap heat rays, blocking their escape in the atmosphere. This was followed by Svante Arrhenius of Stockholm who mathematically demonstrated reducing carbon dioxide (CO2) in the atmosphere by 50% would lower European temperatures sufficiently to approximate an ice age, or a reduction of between 4-5°C and 7-9°F. While demonstrating the sensitivity of the atmosphere to a reduction of CO2, it did not prove that such a change had actually happened or was possible.

Debate about causes of ice age climate change continued into the 1900’s. Carbon dioxide got little attention because of a highly regarded experiment in the early 1900’s performed by Knut Ångström of Sweden.75 Ångström filled a tube with enough carbon dioxide to approximate the level that could be found in a column of air extending up to the top of the atmosphere. He then projected infrared radiation through the tube and measured how much successfully passed all the way through when he doubled and halved the CO2. He found the radiation getting through did not vary significantly with a change in the density of the CO2. He concluded significant climate change could not result from increases or decreases in carbon dioxide.

There were problems, however, with his results. Using a spectrograph of the time, he could not detect differences in absorption because there is hardly any absorption in the solar spectrum, causing him to conclude the CO2 spectrum was saturated. He did not know absorption of CO2 increases in parts of the spectrum he could not observe. He and other scientists were unaware that absorption at sea level air pressure and temperature produced a different result than was found in the much colder and lower pressure upper atmosphere. In addition, water vapor, which also blocks infrared radiation and is far more prevalent in the atmosphere than CO2, overlapped the smeared out bands of the CO2 in the spectrographs. As a result, more CO2 in the overlapping bands would have no effect since water vapor coupled with the CO2 in the tube, was already blocking all of the potential radiation. These results were widely published and caused several decades of neglect of CO2 and its effects by the world’s scientists.

While other research provided key insights into global climate change, two efforts deserve mention. Roger Revelle, an oceanographer who headed the Scripps Institution of Oceanography in California refuted the long held scientific view that CO2 from the burning of fossil fuels would not stay in the atmosphere for long but instead would be absorbed by the huge mass of water represented by the world’s oceans. Revelle’s research in the late 1950s showed that increasing numbers of CO2 molecules added to the atmosphere would wend their way into the world’s oceans within a few years. However most of the increase in additional CO2 would be evaporated back into the atmosphere in a short period of time. This contradicted the long held belief that the oceans were an immediate and natural, long term repository for greenhouse gases. It could take thousands of years for a new equilibrium to be established between the air and sea water.

Other research commissioned by Revelle through the International Geophysical Year, was undertaken by Charles David Keeling beginning in 1959. Keeling established a baseline of atmospheric CO2 values around the world that could be used for future comparisons. Using equipment in Antarctica and at the top of Mauna Loa volcano in Hawaii, Keeling performed painstaking measurements of concentrations of CO2 for many years. His results showed an increase in carbon dioxide that could only be predicted if the oceans did not absorb the continually increasing industrial emissions. They showed a relentless year-over-year increase in CO2 in the atmosphere.

For many decades there were four main obstacles to demonstrating the contribution of human activity to climate change. The first was insufficient historical information on the temperature variation of the planet. This was overcome by studying the chemistry of ice core samples extracted from drilling in the Soviet Antarctic and Greenland ice caps. These samples contained tiny air bubbles from various geological periods and made it possible to measure past CO2 concentrations when the samples were cleaned, crushed in a vacuum and measured for what came out. These two ice core studies looked back some 150,000 years to produce dramatic conclusions. They showed CO2 in the atmosphere went up and down corresponding closely to the rise and fall of temperature throughout the relevant periods. This indicated a direct correlation between carbon dioxide and climate change.

Another obstacle to progress was the need for computing power to perform the millions of calculations required by large scale modeling of the weather.76 For decades scientists built simple models based on limited assumptions and variables to predict large scale weather effects. All of these efforts failed. Only with the advent of big digital computers in the 1980’s could one construct sufficiently complex models to accommodate the required computations of a convincing weather model. And the availability of powerful and fast desktop computers provided speed and computational power required to make even simple models more productive. These two enhanced levels of computing were necessary to move global climate models to the descriptive success they have achieved today.

The third obstacle was the global nature of our planet’s weather and oceans and the lack of worldwide measurement data. Only continuous collection of accurate weather and temperature information from thousands of locations worldwide could supply large-scale models with enough data to support accurate modeling. Obtaining this data involved painstaking daily efforts from thousands of scientists. Sharing the information involved the close cooperation of research institutions and governments around the world.

Time was the final requirement for progress in demonstrating causes of climate change.  Computing models became more complex because of higher numbers of variables.  This meant more time was required for refinement of the models.  With all large statistical models, increased accuracy is a result of countless reruns with selective additions and modifications of variables to insure continuous and steady improvement. There are now numerous sophisticated large-scale weather models at research and educational institutions that have gone through three decades of refinement to improve the statistical predictability of their results.

These models include atmospheric phenomena such as the behavior of updrafts carrying heat from the surface of the planet to the upper atmosphere, the role the layers of atmosphere play in the overall climate, wind currents and quantities of heat carried from the tropics to the poles, how snow and ice reflect sunlight into the atmosphere, and the formation and effects of clouds. Factors concerning the oceans include the interaction of evaporation, storms, and clouds. In addition they include the water currents that carry heat from one part of the globe to another and the oceans’ ability to act as a carbon sink, absorbing CO2 from the atmosphere and storing it. In addition the models must account for airborne particulates in the atmosphere such as chemicals and dust from volcanoes and aerosol sprays. Other elements to be added to the models are greenhouse gases produced by human beings and other forms of life, such as CO2 from the burning of fossil fuels and methane, which is released into the atmosphere by livestock and microbes in wetlands and rice paddies. We also have to include variables from beyond our planet such as radiation from the sun, its angle of impact on the earth and shifts in the planet’s axis and magnetic fields. You can now begin to appreciate the sheer complexity of factors that needed to be considered.

The history of climate change has been fraught with controversy. As could be expected with burgeoning interest in the issue by scientists, governments, industries, and finally an aware citizenry, there has been much acrimonious debate. Confusion has arisen over conflicting findings, criticism of research methodologies and questions about individual motives. Mainly we become frustrated by our inability to make complex issues more simple and straightforward.

There have been numerous opinions, some of which are more informed than others, and numerous participants in the debate. One organization, the Intergovernmental Panel on Climate Change (IPCC), received worldwide endorsement of its findings. The IPCC was chartered by the World Meteorological Organization (WMO) and the United Nations Environment Program (UNEP).  Since its charter, the IPCC has issued four major world assessments of climate change, in 1990, 1996, 2001 and 2007.77 The due date of the next assessment is sometime between the end of 2013 and 2014.  Along with former Vice President Al Gore, the IPCC received the 2007 Nobel Peace Prize.78

The IPCC has three working groups that deal with different aspects of the global climate change issue; the scientific basis of climate change, its consequences, and remedies the world has for slowing the rate of change. The process for review and consensus of the IPCC’s reports is extensive and involves collaboration and review by thousands of scientists from the developed and developing worlds, research institutions, industry, government and non-governmental organizations (NGOs). The reports are issued only after several layers of authorship, review, and negotiation.

Conclusions that have emerged from the reports of the three working groups are as follows:79,80,81

  • There is a greater than 90% probability that the increase in the world’s average temperatures since the mid-20th century is due to greenhouse gas concentrations as a result of human activity.
  • Warming of the climate system is unequivocal.
  • The “best estimate range” for an increase in global temperatures is from 3.1 to 7.2 degrees Fahrenheit (1.8 to 4.0 degrees Celsius) by the end of this century. More pessimistic estimates identify average temperature increases as high as 11.5 degrees.
  • There will be increasingly severe weather including fewer but more intense hurricanes and typhoons, greater rainfall in higher latitudes with decreases in precipitation in the more subtropical areas.
  • Fresh water resources will diminish affecting one sixth of the world’s population living near rivers with water from glaciers and snow cover. An early increase in available water as the glaciers melt will be followed by a steep decline as glaciers disappear.
  • There will be a potential shrinkage of fresh water resources by an estimated 30% by the middle of this century.
  • Disappearing glaciers, melting Arctic and Antarctic ice and melting snows will cause a most likely 7 to 23 inch rise in sea level by the end of this century.
  • Some researchers believe the forecasted increases in temperature will initiate an irreversible melting of Greenland’s ice sheet. This would cause a rise in sea level as great as 23 feet.
  • Global climate change threatens up to 30% of plant and animal species with extinction if the global average temperature rises more than three to five degrees Fahrenheit.

Unfortunately there is no silver bullet, no single step that can be taken that will slow or reverse the climate change that has begun. A wide array of recommendations have been made which would have major impact on numerous industries including the seven sectors of Energy Supply, Transport, Buildings, Industry, Agriculture, Forestry/forests and Waste. Unfortunately recommended changes would require development and adoption of many new technologies and would initiate wholesale replacement of infrastructure in multiple industries. These changes would necessitate large societal investments and would take many years to accomplish.

Prominent among steps identified for Energy Supply, Transport, Buildings and Industry sectors are:

  • fuel switching from coal to gas
  • nuclear power and use of other renewable sources such as hydropower, solar, wind, geothermal and bioenergy;
  • production and use of more efficient vehicles including hybrids and cleaner diesel vehicles
  • more efficient building lighting, heating and cooling systems
  • use of passive and active solar design for building environmental systems
  • more efficient use of electrical equipment in industry
  • increased material recycling and substitution and
  • greater control of non-CO2 gas emissions.

In the longer term in these sectors, the IPCC is suggesting:

  • technologically advanced nuclear power and alternate renewable energy sources including tidal and waves energy and solar power
  • more advanced and efficient vehicles and batteries and
  • Carbon Capture and Storage for cement, ammonia, and iron manufacture.

In the agriculture, Forestry/forests, and Waste sectors they called for:

  • increased crop and grazing land management
  • livestock and manure management to reduce CH4 emissions
  • dedicated energy crops to replace fossil fuel use,
  • reduced deforestation and reforestation
  • landfill methane recovery
  • greater composting of organic waste and
  • recycling and waste minimization.

Global climate change is an urgent, long-term problem facing the planet and all of its inhabitants. In an article entitled The Physical Science behind Climate Change, which appeared in the August 2007 issue of Scientific American, five noted scientists, William Collins, Robert Colman, James Haywood, Martin R. Manning and Philip Mote, conclude “One result of global warming is certain, however. Plants, animals and humans will be living with the consequences of climate change for at least the next thousand years.”82

As we observed part of the difficulty of dealing with climate change is that it is complex, diffuse, and central to post industrial society. Numerous industries will have to make significant changes and their responsibility is unfocused. Suggested remedies will take considerable time, effort, and money to accomplish. The two most significant challenges to begin the task of addressing global climate change are a sense of urgency and finding strong leadership.

The issue now moves from the scientists to the politicians, industries, and the individual citizen. Unfortunately the country that ostensibly leads the world, the United States, is the largest contributor to global climate change by any measure and has been the most intransigent on the issue. And the science is conclusive. The Editor-in-chief of Science magazine, Donald Kennedy, observed in an editorial “The scientific consensus is clear … political judgments are in, and the game is over.”83 It is now time for the United States to mobilize the needed action including ambitious and aggressive legislation to begin addressing the problem.

Following a “Politics as usual” approach to the problem, the motivations and actions of various participants will be as follows. Politicians in response to public pressure know they must sponsor and/or vote for one or more global climate change bills that at minimum give the appearance of taking action. Representatives of affected industries will proclaim leadership of and commitment to the “Green Revolution” in their advertising while attempting to negotiate the least required change that will spread over the longest period of time. They will also claim costs are too high, needed technology is non-existent, and as a result their business will be less competitive. Finally, they will argue that conversion costs should be borne by the government, in other words, the taxpayer.

The collective tendency will be to postpone the hard work for future generations of business leaders and politicians who will be forced to act. Citizens will look to politicians to demand that offending industries change and yet themselves will take largely symbolic acts to show support for resolving global climate change. The bottom line is everyone will wait for someone else until it is clear we are out of time. The risk to humanity is huge. Future generations will lose because they were left with no chance to win.

A number of bills were introduced in the U.S. Congress in the last few years that proposed various plans for greenhouse gas reductions in the United States. These bills identified when the emissions limitations would go into effect, set percentage targets for annual reductions of greenhouse gases, and fix a maximum target for a specific year in the future. They were variously entitled the Global Warming Pollution Reduction Act, Safe Climate Act, Global Warming Reduction Act, Climate Stewardship Act, Climate Stewardship and Innovation Act, Electric Utility Cap and Trade Act, American Clean Energy and Security Act, and so on. None of these bills have passed both houses of Congress. None were expected to.

The starting years for proposed laws ranged from 2010, which has been missed, and later. The arguments and lobbying continue. The original measurement milestones called for emissions reduction from 8% at the lowest end to 17% at the high end by the year 2020. They further specified a final milestone ranging from a total emissions reduction of 42% at the low benchmark to 83% emissions reduction at the highest level by the year 2050. Now that we have experienced a significant economic downturn, it is unclear when the United States will muster the will, energy, or resources to attack the problem.

The question is, are any of these proposed laws aggressive enough? Some perspective would be useful. If we use other human undertakings as a benchmark we have a frame of reference with which to evaluate proposed legislation. Let us use three human accomplishments for comparison; the construction of the great pyramid at Giza, the making of the first nuclear weapon, and putting a man on the moon. The Great Pyramid of Khufu in Giza, Egypt sits on an area of thirteen acres.84,85 It is composed of approximately 2,300,000 stone blocks, each of which required 112 men to lift and move into place. It is estimated to have taken 20 years to build.

The phenomenon of a chain reaction initiated by the splitting of atoms was articulated in 1933 by a Hungarian physicist Leo Szilard. He patented the idea. In October of 1939 Szilard wrote a letter, which Albert Einstein signed, to President Roosevelt advocating the building of a bomb. The first atomic explosion was conducted on July 16, 1945. Two atomic bombs were dropped on Japan in 1945. From conception in 1933 to use in 1945 took twelve years.

On May 25, 1961 President John F. Kennedy delivered a speech declaring the United States was going to put a man on the moon. Eight years later Neil Armstrong took the first steps on the moon.

These three human accomplishments took 20 years, 12 years, and 8 years respectively, and yet the most aggressive proposed legislation to deal with global climate change allows a time frame of over forty years. The author of this legislation was the Speaker of the House who was born in 1940 and will be 110 years old in 2050. The Chairman and CEO of Duke Energy, the largest power generating company in the United States, was born in 1947 and will be 103 years old in 2050. Both will certainly be retired by the time the first measurement milestone in that proposed legislation would have been due in 2020.

Humanity must accept the urgency of our situation and summon the resolve to aggressively slow and ultimately reverse global climate change. Unfortunately, humanity does not have a good track record in following through on goals which span decades. Our continuing failures to close the ozone hole and eliminate nuclear weapons serve as examples of our inability to follow through. Present proposed global climate change legislation in the United States Congress is inadequate and will not accomplish our objectives.

We do not know if we have run out of time to reverse global climate change. It may be that climate change is analogous to the AIDs epidemic. People do not die of AIDs. AIDs weakens the human immune system so its victims are susceptible to any number of other infections. Other infections, which we should survive, prove fatal because of the crippled immune system. Assuming we take appropriate action, global climate change may not be fatal, but it attacks the equilibrium of the surface environment of the planet.

James Lovelock, a noted scientist, environmentalist and writer, developed the concept of Gaia or that all elements in the environment on Earth work synergistically to regulate the overall system and rebalance the ecology as a protection mechanism.86 Once the planet’s ecological system has been overburdened with human pollutants, its self regulating and synergistic mechanisms may have been compromised to the point that they cannot absorb further shocks and can no longer respond. Once the relative stability of the world’s temperature has been compromised, we may find we have initiated a sequence of events that reinforce each other into a spiral of escalating effects and deterioration.

As an example, consider the greenhouse gas methane. Methane (CH4) is a greenhouse gas that is emitted from a variety of natural and human initiated sources. Human sources include landfills, natural gas and petroleum systems, agricultural activities, coal mining, stationary and mobile combustion, wastewater treatment, and certain industrial processes.

What makes methane a source of concern is it is the most likely greenhouse gas to cause catastrophic change. Methane is over 20 times more powerful and destructive than CO2 but it remains in the atmosphere for only about a decade. Methane occurs naturally all over the planet and in significant quantities. It is frozen into hydrates, or crystalline structures, under sediments on the ocean floors and in frozen tundra.87 If the tundra and permafrost melt or the temperature of the ocean increases over the next couple of decades a significant release of methane could occur which would accelerate climate change. Seafloor methane hydrates, especially those deposited on continental shelves, are also susceptible to earthquakes and underwater landslides which can trigger immediate significant releases of the methane gas.88

Climatologists and geologists have created many variations of a hypothetical series of events that would indicate “a methane runaway is possible, sustained by three mutually reinforcing sources, one Arctic, one tropical, and one global.”89 Most of these hypothetical series begin with an initial methane release, that is the crucial triggering event that causes other events negatively reinforcing each other establishing a series of effects that spiral out of control. For example, Nisbet (1989, 1990) points to a release of gas from an Arctic gas pool while Paull et al. (1991) suggest a submarine landslide could release large amounts of methane triggering a rise in the planet’s temperature which causes melting of frozen tundra which releases more methane that increases the temperature even more, and so on. “An important factor is the possibility of mutual feedback between submarine landslips, Arctic hydrate releases, and tropical wetland emissions (Nisbet 1992).”

Some years ago, in the midst of the U.S. and Soviet cold war, there was recognition in the scientific community and the government that an enemy could avoid detection in a nuclear attack by exploding a weapon off the coastline. This would trigger a tidal wave that would devastate coastal cities. Such an attack or for that matter, an explosion by a sizable meteor hitting the ocean near a methane rich continental shelf could trigger a release of methane with catastrophic consequences. Such an event could cause a weakened planet to enter a methane runaway that would overwhelm human responses.

A generation is usually measured as the time from birth of a parent to the birth of their first child. This varies from generation to generation and most recently has become longer as people have their first child later in life. At present the length of a generation in developed countries is approximately 30 years. A global climate change problem that lasts 1,000 years will affect over 30 generations. We are dealing with a problem that even under the best of circumstances will threaten our great, great, great, great, great, great, great, great, great, great, great, great, great, great, great, great, great, great, great, great, great, great, great, great, great, great, great, great, great, great grand children and all children in between.

We all know that since the beginning of the industrial age, human industry has looted the resources of the planet. Businesses and governments have considered those resources in economic terms a relatively free good available for plunder. Everyone in the civilized world has benefited from their extraction and use even as we have polluted the environment. As time passed, many people began to suspect that at some point we would have to pay a price for our exploitation. It is now clear the time has come to fix what we have done. Climate change and the ozone hole join nuclear weapons as the three creations of human kind that threaten life’s existence on Planet Earth.

While climate change is uncertain in its future severity, we humans cannot afford miscalculation. We cannot rely on serendipity. The risks of being wrong and failing to respond in an aggressive and conclusive way are unacceptable. We must insist our political leaders discard a “politics as usual” philosophy. We must demand that instead of requiring progress from our industries on the back-end of the time allowed, urgent progress must be front-end loaded. We will fail with plans that offer 83% reduction after 40 years. We must demand the 80% in the first 15 years. Only in this way can we give ourselves any substantive chance to avoid catastrophe.

Yes, our effort will cost money and require we move forward with technologies as they are, while we develop others. Yes, our actions may be wasteful as yesterday’s solutions are immediately replaced by the next generation of technology in short order. This is how humanity will succeed and how progress will be made. This is how we will win against global climate change. Unfortunately, it appears we will not react in time to permit an orderly and systematic, well planned response. Every month of delay increases the severity of the steps that must be taken and the human cost of future suffering.

There is nothing sacred about how we live presently. Cities can be changed. Transportation can be changed. Economic policy can be changed. Everything can change. We must not hold on to failing processes, technology or institutions. We cannot let our grasp on the familiar keep us from reaching for the future. We must do as only we can do. We have identified this problem, absorbed large amounts of information about it and are clear on its consequences to our existence. We must identify available options, decide on a course of action, and implement those actions.

Beyond Animal, Ego and Time: Chap 7 – An Evolutionary Imperative, Chap 8 – Life’s Optional Future, Chap 9 – A Positive Life Experience

Posted on 13 March 2013 by admin

I’ve decided to serialize my book on this website.  As an incentive to readers to return to the site, each month I will post at least one Chapter of the book until the entire book is posted.  Go into the Archives to “Beyond Animal” for earlier chapters.  The book provides context for the blog, clearly explaining the underlying philosophy and identifying critical issues of our time. I believe that Chapter 8 is a pivotal chapter which sets the stage for the remainder of the book.

CHAPTER 7 

An Evolutionary Imperative

Scientists have identified the human brain’s highly developed right prefrontal cortex as potentially responsible for self awareness, empathic emotion, and significant contribution to conscious thought and decision making. These attributes are among the most highly evolved of life. While apparently a result of the brain’s physical evolution, intellect, which includes thought, knowledge, and consciousness, has its own path of development. Intellect also informs emotion contributing to a third area of further evolution. It has led to a higher order of emotions beyond the primitive feelings of fear and aggression. Higher states of emotion include insight into shared circumstance (empathy), recognition of vulnerability to negative events (sympathy), and optimism about future outcomes (hope).

To understand the future potential of life we must look at evolution as the most powerful process guiding its development. Anticipation of future advancements may help us recognize when they occur and position us to contribute to their development. We must admit, however, that we may not be aware of them when we experience them.

For example, the rest of the animal kingdom cannot perceive our development of self awareness nor understand how different it makes us. Consider how recent it was that we learned other animals are also self aware. This should cause us to pause when we encounter life behaviors or characteristics we have never seen before. Since we consider ourselves at the pinnacle of evolution our understanding may be key to future progress. For these reasons we will look further at physical, intellectual, and emotional evolution.

There are at least three forces influencing the progress of physical evolution. The first is random mutation and resulting genetic modification. This occurs when alteration of a DNA sequence results from errors during replication or repair of DNA. Other changes take place through recombination of DNA sequences as a natural result of cell division. They often have no apparent effect until an environmental event selects and favors the change. Even small genetic alterations can have significant impact because they can exist over long periods of time and combine with other unseen mutations until environmental change makes their effect and existence apparent.

The second force shaping evolution is selective breeding. There is an inherent genetic and biological drive within animal species to select breeding mates that exhibit preferred characteristics. This mate selection is based on factors generally specific to the species such as physical stature, dominance, and plumage. Well documented in the animal kingdom, this behavior is also apparent within humans. Mate selection within human kind has a wider set of criteria which can include intelligence, personality, or can be the result from the often inexplicable emotion defined as love. Beyond selective breeding within species, we have practiced selective breeding of agricultural crops, livestock, and pets for centuries. We have done this to produce characteristics we value.

The third force impacting physical evolution came into existence within the last fifty years. This is the human science of genetics, more specifically genetic engineering and its successor synthetic biology. The tools are now in place to alter the genetic code of any life form at will by using the largely cut and paste technology of genetic engineering. This science has led to a multi-billion dollar, worldwide industry seeking to profit from conscious human alteration of the genetic code of numerous existing life forms and new alien life forms it seeks to create.

Random mutations, selective breeding and thoughtful genetic engineering will undoubtedly prove beneficial in a changing environment. To have the widest possibility of beneficial change, broad diversity of species is desirable. When confronting the impending extinction of a living species, most people only consider the utility of the species to human beings. This is a shortsighted view. In the history of life there have been species other than Homo sapiens that have been the dominant life forms of their time. While ours is a privileged present position, evolution and changing circumstance may favor another. Only the right choices and actions will secure our continued leadership of life.

To put human life in perspective, science considers the age of Earth to be about 4.5 billion years. Life is thought to have come into existence some 3.5 billion years ago. The Homo genus or branch of life leading to Homo sapiens is believed to have begun 1.5 to 2.5 million years ago with modern humans first appearing around 200,000 to 300,000 years ago. While we egotistically assume our position as dominant species will continue indefinitely, such may not be the case. It is generally thought we can survive catastrophes that have befallen previous dominant life forms. We may not be able to survive our own actions. As the preeminent species of conscious decision making we may make a disastrously wrong decision, wait too long to correct a bad decision or just fail to decide to do the things necessary to insure survival.

As it has been in the past so it may be in the future. We do not know if there will be a future ascendency of another life form as the dominant species. Not knowing what life must do to insure its survival, we should view all species within the collective gene pool as potential contributors to the future sustainability of life. When we balance the value of our actions to preserve a species from extinction against the costs of doing so, we must consider that any loss of diversity will diminish the possibility that life will survive.

A note of caution, diversity as a result of natural processes has been tested and refined over billions of years by natural selection. As will be discussed in Chapter 13 on synthetic biology, entrepreneurs now have the ability to bypass the protections offered by the slow and steady process of natural selection. They have the ambition, if not the present ability, to create entirely alien life forms that would never and could never evolve naturally on our planet. Our knowledge of the potential risks is so limited and their possible effects so extreme, it may be doubtful this diversity is desirable.

The second domain of evolution is intellect or advances in human thought in all of its various forms. Intellect is one of evolution’s greatest outcomes. With intellect has come the ability to reason or the power of comprehension, inference, or thought especially in orderly rational ways. With reason has come science and the knowledge humanity now possesses. If we accept Pavlov’s view that curiosity is instinctive, curiosity coupled with human intellect has produced all of our scientific breakthroughs. Breakthroughs have been the result of this burgeoning intellect and knowledge base. They give humans extraordinary control over their environment. They also extend their life spans and lessen human suffering.

The power and progress of human thought has been discussed by countless philosophers. Descartes who spoke of it as a proof of existence itself asserted “I think, therefore I am.” Hegel with his theory of the dialectic cited a thesis giving rise to its own antithesis and an ultimate synthesis as the way thought advances.

With the evolution of intellect has come abstraction or the ability to see a quality apart from an object. This has led us to define and classify categories that only have existence in thought. An example is the consciousness of self. It gave us recognition of our own existence and the concept of “I”. With intellect, this consciousness has been raised to progressively higher orders of thought. From “I” came recognition of “We” as the individual perceived the connectedness and relatedness of other human beings and life forms. This progressive abstraction of relatedness brought concepts of nation, race, species and the aggregation we call life itself. These successive levels of consciousness represent the best evolutionary progress of intellect.

The greatest advance of human thought occurs when it rises to the highest levels of abstraction. This level of abstraction is most productive in reaching for the greatest truth and common good. It was from the higher states of consciousness that founding fathers of the United States wrote the Declaration of Independence. The thoughts and phrases, “all men are created equal” and “unalienable Rights” and “Life, Liberty and the pursuit of Happiness,” continue to have profound effect beyond their nation of origin. From an equal level of abstraction, that of a “Community of nations” came a movement to create the United Nations.

The ability to abstract an idealized state to which we can direct our action is one of our most advanced intellectual capabilities. These are examples of the power of thought to shape the destiny and future of humanity. Others could be identified from the systems of thought developed and refined in the fields of science, philosophy, and religion. This evolution is as important as the physical evolution with which we are most familiar. This intellectual evolution will undoubtedly produce more knowledge, more insights, and higher levels of consciousness. As stated at the outset of this book, we have learned that greater knowledge and understanding increase our ability to shape and impact our surroundings to better support our lives. As it is true for our individual and collective lives, so it is also true for all of life.

As observed, intellect informs emotion which has led to a higher order of emotions beyond primitive feelings such as anger and fear. Higher states of emotion include those based on insight into shared circumstance (empathy), recognition of another’s vulnerability (sympathy), and optimism or pessimism about future outcomes (hope or despair). Anyone who has experienced pride at a significant human accomplishment such as our landing on the moon or whose eyes have welled with tears at a wedding or marveled at the sheer beauty of classical music has experienced a higher order emotion. Anyone who has donated to disaster relief in response to catastrophic human hardship or has administered first aid at the site of an accident or has affirmed a relationship “until death do us part” knows the force of a higher order of emotion to commit us to action.

Emotion is the third path of evolutionary development. The behaviors it elicits have long been a source of controversy amongst philosophers and scientists. It has been much maligned, as intellect and its byproduct, reason, have been elevated as the ultimate human capability. Emotion has often been referenced as primitive, inferior, unreliable and something that must be conquered and controlled by reason. Most often viewed as separate capabilities, much research has been devoted to reason and emotion attempting to identify and pinpoint specific sites or regions of the brain responsible for each.

Research involving neurological patients whose social behavior had been altered by various types of brain damage has shown processes in the brain and throughout the body are more complex and interdependent than once believed. It indicates consciousness, decision making and emotion are intertwined.

One significant proponent of this view is Antonio Damasio, the M.W. Van Allen Professor and head of Neurology at the University of Iowa. In his book Descartes’ Error: Emotion, Reason, and the Human Brain, he observes that brain damaged patients who are unable to process emotion also suffer impairment of their ability to make rational decisions about everyday problems.56 While reasoning and logic skills are shown when patients identify alternatives to be considered in decision making, their ability to resolve an analysis and decide is impaired. Damasio attributes this impairment to the lack of emotional evaluations that provide crucial input to decision-making.

“I propose that human reason depends on several brain systems, working in concert across many levels of neuronal organization, rather than on a single brain center. Both ‘high level’ and ‘low-level’ brain regions, from the prefrontal cortices to the hypothalamus and brain stem, cooperate in the making of reason. The lower levels in the neural edifice of reason are the same ones that regulate the processing of emotions and feelings, along with the body functions necessary for an organism’s survival. In turn, these lower levels maintain direct and mutual relationships with virtually every bodily organ, thus placing the body directly within the chain of operations that generate the highest reaches of reasoning, decision making, and, by extension, social behavior and creativity. Emotion, feeling, and biological regulation all play a role in human reason.”57

Further support for this view is provided by research in cognitive neuroscience, an interdisciplinary approach to investigating the nature of thought, which has increased our understanding of the interaction of various parts of the brain to produce an emotional experience. Joseph LeDoux at the Center for the Neuroscience of Fear and Anxiety at New York University, in The Emotional Brain cites the interaction of subcortical structures, the amygdala, hypothalamus and brainstem, and the cingulated cortex and the prefrontal cortex as the source of an emotional experience.58 These parts of the brain work in concert for example to enable us to feel fear when we see a stranger approaching in a dark alley. Involvement of the cerebral cortex enables us to recall similar circumstances in the past and recognize the danger in the present. Based on our memory of bad past experience, our sub-cortical structures enable us to reflexively experience an increased heart rate, tensing of our muscles and perspiration.

A fundamental question about emotions has been their origin. Are they innate and somehow hardwired as a result of evolution or are they taught and a product of the cultural environment? If a product of evolution and hardwired in the human being, they should be universal across the human species irrespective of culture, language or ethnic background. Paul Ekman, a noted clinical psychologist, focused on observable facial expression looking for commonality across widely diverse cultures.59 His research documents distinctive universal facial expressions for a small list of basic emotions: anger, fear, disgust, sadness, and enjoyment. The research results are somewhat less clear for other emotions such as contempt, surprise, and interest.

Ekman observes this list of “universal” emotions is far shorter than lists most theorists identify and is a much smaller number than the various words that describe different emotions. This suggests that beyond basic emotions resulting from evolution, a different phenomenon is taking place to account for the other emotions human beings report they experience. He speculates there may be emotions not related to specific facial expressions or that grouping emotions into families may offer an explanation or that a number of emotions share one facial expression. It seems likely there may be another explanation, that where physical evolution leaves off, intellect, experience and memory take over.

These findings suggest a small number of evolved emotions serve as a foundation for an intellectual, emotional, and experiential feedback loop that expands the variety of our emotions. It defines a common emotional platform within each human being. We can conceive of coequal intellectual and emotional contexts for each of our experiences that we commit to memory as we live our lives.

An example will serve to illustrate this. As a father runs beside a bicycle, he holds the handle bars and seat steady during his daughter’s first bike riding experience. Sensing the child is ready, he pushes off launching her on her own. At this moment she takes control of forward motion as all of her faculties concentrate on maintaining balance. Her intellect is engaged as she concentrates on the actions she is performing. Her major physical sensory systems record her instinctive reactions as she steers, pedals and maintains her balance. Her emotions surge with her simultaneous fear of falling and thrill of accomplishment. After the initial awkward and scary moments she proceeds to ride around the parking lot for awhile as her dad says “I knew you could do it” congratulating her on the accomplishment. Fear gives way to happiness as the child experiences pride.

There are intellectual, emotional and sensory memories created by this experience. The point of the example is that multiple dimensions of every experience are committed to memory and exist for future recall and use.60As we gain knowledge and further insight, we refine memories creating additional layers of nuanced information and emotion for future recall.

Damasio sees intuition as a sort of shorthand memory of past circumstances. He writes, “Emotion had a role to play in intuition, the sort of rapid cognitive process in which we come to a particular conclusion without being aware of all the intermediate logical steps. It is not necessarily the case that the knowledge of the intermediate steps is absent, only that emotion delivers the conclusion so directly and rapidly that not much knowledge need come to mind.”

He further observes “that the quality of one’s intuition depends on how well we have reasoned in the past; on how well we have classified the events of our past experience in relation to the emotions that preceded and followed them; and also on how well we have reflected on the successes and failures of our past intuitions. Intuition is simply rapid cognition with the required knowledge partially swept under the carpet, all courtesy of emotion and much past practice.”61

When we began this discussion we stated that intellect informs emotion. Our self awareness and ability to project how we would feel if circumstance that happened to another happened to us creates feelings of empathy and/or sympathy for another. At the core of this emotional reaction, which does not appear in Ekman’s universal emotions, is the intellectual recognition that human beings share similar circumstances. While it can be argued empathy and sympathy may be an extension of sadness, the sadness is informed by intellect to represent a higher state of emotion.

Emotions play an integral role in our lives. They have enhanced survival as we have evolved. They are inseparable from experience, intellect, and decision making. They moderate our behavior as they affect our decision making. As our intellect, knowledge, and consciousness evolve so do our emotions. Much of what we know is learned. This is also true of what we feel. Just as the parent congratulated the child on the accomplishment, the parent taught the child to feel pride. We are not as conscious of the need to teach children to experience higher emotions and yet they are as crucial to our continued evolution as the higher states of intellect that enable them.

When exploring human uniqueness we observed our ability to learn vicariously without personal experience is a key human attribute. Experience of art in all its forms contributes to the emotional development of children. Story telling by the written word or in movies provides a vicarious way to experience emotion. It can convey insights that inform emotions and can trigger feeling an emotion not felt before. The beauty of art and music can lift the spirit and raise emotional consciousness.

Parents must recognize that while art can move emotion forward, it can also create regression to more primitive emotional states. While the beauty of art should be sought, gratuitous vicarious violence on television and in movies can move anyone’s emotions to a lower evolutionary level. If a child sees violence, it must be understood through a parent’s lens of interpretation and explanation.

Above all, we must look for evolutionary progress because it can originate anywhere and from anyone. Evolution after all is blind to the humble origins of a patent clerk who conceived of E=MC2, to the physical infirmity of a Cambridge astrophysicist who enlightened us about black holes and the universe, and to the sexual orientation of a musician who moved the emotions of 33 million people bringing us the biggest selling song in history, Candle in the Wind. We cannot predict the origin of future breakthroughs or who will be responsible. For this reason we must help others achieve their full potential and be open to their contributions to future progress.

CHAPTER 8 

Life’s Optional Future

Life and its evolution are extraordinary. Up to now we have spent considerable time identifying basic assumptions to be used in the foundation of our new cosmological perspective. Our investigation of the physics of the universe, life, human uniqueness, and evolution will help us reintegrate our knowledge with our beliefs. We can now draw on these basic assumptions and speculate about future possibilities, as we build the next tier of our belief system.

To do this we must move our focus from knowledge to belief and from what has occurred in the past to what is possible in the future. We advance from the more certain to the hypothetical. As with the articulation of any hypothesis, we define an area of future study posing a new question that once asked launches new investigation.

While all knowledge is based on belief, its categorization as knowledge implies a higher justification,62 such as verification through repeated experimentation or corroborated occurrence as reported by multiple observers. For this reason, knowledge has a higher standing than belief which has not necessarily passed all of the tests to which knowledge has been subjected. A belief is more of a hypothesis. While it may be highly supported by logic, reason, and experience, it does not have the same force and credibility as knowledge.

Similarly, documented events that are known to have occurred in the past have a higher level of certainty than those that are predicted to occur in the future even if they are highly probable. While multiple observers can disagree on the description of a past event because of different perspectives or interpretations, the event is still more certain than that which has not yet happened.

Our objective is not to diminish the value of beliefs or possible future events but merely to recognize the transitions we are making. Beliefs are after all often a precursor of knowledge. We previously identified that new knowledge is frequently the answer to a question that has not been asked before or has been posed but not answered over the centuries. When acknowledging the possibility of a future occurrence we stimulate the human consciousness to think about the possible future event and how it might be accomplished. This in turn is often the first step toward realization. Without the belief that human beings could someday fly and the act of imagining that future possibility, there would have been no airlines to dramatically shorten travel to any place on Earth. In this way beliefs and future possibilities are inextricably tied to human progress.

As we work to construct new hypotheses, our tentative conclusions should seek to be logically consistent and answer basic questions of the meaning of life and human purpose. As we attempt to project known physical processes forward in time, we explore possible future states that challenge our sense of normalcy, increase our intrigue with that which is not known, and stimulate our imagination. We must look for inspiration and an individual vision that provides motivation to sustain a new direction.

To borrow a thought from an old riddle, if two galaxies collide and there is no astronomer or physicist to perceive the collision, is it really happening? Scientifically the answer is yes, the galaxies still collide. If there is no life to perceive it however, there is no awe, no majesty, no wonder, no appreciation or interpretation of the event. Beyond life and its animation, we bring meaning and feeling to an inanimate universe.

This is why we are moved emotionally in the classic movie Blade Runner when the Rutger Hauer character, Roy Batty, the combat model and leader of the renegade Nexus 6 Replicants, is dying after having saved Rick Deckard, Harrison Ford, from falling from the roof of a building. “I’ve seen things you people wouldn’t believe. Attack ships on fire off the shoulder of Orion. I’ve watched C beams glitter in the dark near the Tannhäuser Gate. All those moments will be lost in time, like tears in rain.” He accepts his fate with a sad smile and his final line, “Time to die”. Without his witness, experience, and interpretation of those events, they have no meaning. Beyond this movie character, it is our life and witness that brings quantitative and qualitative richness and gives meaning to all that surrounds us.

What if Roy’s memories are not lost with his death? What if his memories, and ours for that matter, are indelible, permanently etched on life’s matter so they can be recalled after death when Roy’s and our matter is once again reintegrated into a living system?

To reiterate briefly, we know life’s matter has memory at the person and organism level. The trillions of cells composing each of us have knowledge of us. This cellular knowledge includes the estimated 20,000 individual genes that account for what the Human Genome Project identified as over three billion base pairs.

Beyond genetic information, we remember the knowledge we’ve learned and our experiences because they are stored or encoded somehow on the matter within us. This includes the thousands of faces and places we remember for many years in our lifetime. Sometimes when people cannot remember the details of a past event hypnosis is used to help them recall those details. This is because the memory is there but is blocked from immediate recall.

We are uncertain about the mechanisms that create memory and how our memory is encoded. We also do not know what levels or layers of our matter participate in the storing of this information. It is generally accepted that memory takes place at the cellular and molecular levels and involves neuron cells which are specialized to pass signals to other cells through chemical and/or electrical synapses or specialized connections between those cells. Both the pre-synaptic and postsynaptic sites contain extensive molecular structure that link the two cellular membranes together and carry out the signaling process.

We know memories are encoded at the cellular and molecular levels in the body. We cannot see individual atoms because they are thousands of times smaller than the light waves we can see using our eyes. Even though we can’t see them, with a scanning tunneling microscope we can use an extremely sensitive probe to feel around the outside of solid materials and perceive the bumps that are made by the individual atoms. Computer imaging software can turn these bumps into an image representing the surface of the solid and individual atoms lying there and the patterns they form. Since we cannot see them however, we do not know if and how atoms and/or particles participate in storing our experiences.

It is not reasonable to assume that because we lack the tools for perception at the atomic and particle levels that no storage of memory takes place there. It is reasonable to assume the encoding of memories occurs at the smallest levels of matter in the body and that as with the hologram, the equivalent of interference patterns are etched on atoms and particles. We assume therefore that memory occurs at all manifestation levels of matter; cellular, molecular, atomic, and particle.

Given technological advances and our recent scientific experiences of retrieving information that was once thought lost from living and once living material sources, it is possible our life memories and genetic code are indelibly encoded on our matter. There is a reasonable possibility that when matter is incorporated into a living system the encoding of experience and knowledge is irrevocable. We know our bodies are composed of elements whose atoms are stable, which in turn are composed of stable particles. Stable atoms and particles have lifetimes that last into the billions of years. This would make the knowledge and memory of life endure perhaps forever.

We assume therefore that matter is irrevocably changed by participating in a living system with its knowledge and memory indelibly encoded or etched on its constituent parts. To this assumption we must add our knowledge that genetic material from fossil bone fragments when inserted in the cells of another living organism can be replicated as its cells divide and multiply. In addition, we know that genetic material from the 100 year old remains of the extinct Tasmanian tiger has been shown to perform normally when reintegrated into a living system.

Our assumptions and the facts we know about once living matter being reintegrated into living systems, such as bacteria and mouse embryos, lead us to recognize a very significant possibility. It is possible that all of the life matter retained in the biogenic sphere that surrounds our planet has the opportunity for future reintegration with a living system. One can imagine living organisms ingesting, growing, and incorporating matter from their surroundings into their life system and obtaining a random mix of the once living matter’s past life experiences.

We can conceive of a coherent thought or memory being transferred from the past into the present. This is possible if our experience is etched on our matter in a way similar to a piece of a larger hologram. If this were so, each increment of matter retains in miniature a representation of the entire image or in this case memory from a specific perspective.

Without knowledge of how memory is stored a more likely description of what is recalled of past life experience is tiny fragments of unrelated experience or emotions. When one considers all of the many millions of different organisms that are contributing matter and the many different types of living organisms that are receiving matter, it would seem the impact would be minimal. Possibly the memory of an emotion is more easily transferred to the new living system than a coherent thought or complete memory. This might be because it is inherently less complex and more easily translated. In any case, this need not change the reality that the encoded knowledge and experience exists and can be retrieved and utilized by its new life system.

This new thought, that life’s indelibly etched knowledge, experience, and memory can be recalled and used by future life forms of which it is a part, becomes a key assumption of our new cosmology. These three assumptions that matter has memory, the life memory is indelibly etched on matter and survives the death of the organism, and that once-living matter can be reintegrated within a living system to “live” again, are key underpinnings of one of the four major imperatives discussed in the second half of this book.

Of course they also raise a number of questions that take us into more speculative areas about what may be possible. The first question that comes to mind is will it someday be possible to recreate living examples of extinct animals? Would a Jurassic Park scenario be possible?

In the example of our mouse embryo reintegrating genetic material from an extinct Tasmanian tiger, it was the existing life system of the mouse embryo that incorporated and enabled the tiger’s genetic material. In another example, discussed in the chapter on Synthetic Biology, genetic material that was fabricated in a laboratory was inserted into a living bacterial cell. The cell accepted the new genetic material, changed the cell’s fundamental nature, and went on to divide and multiply naturally. In both cases, the existing living organisms were critical to the success of the experiments.

The complexity of a Jurassic Park scenario is daunting. Its biggest barrier is that no one has successfully initiated the beginning of new life in a laboratory. This is not to say it will not be possible some day. We certainly have indications it is or someday will be possible to decode the extinct animal’s genetic code and create the necessary genetic material in a laboratory. Spontaneously bringing it to life may remain the hard part. In the nearer term it is more likely the genetic code may be integrated into an existing living system under conditions similar to those of our two examples.

A second question that comes to mind takes us back to Roy Batty, our fictional combat Replicant. If after Roy’s death we were able to keep his matter from dispersing into the environment and mixing with other matter or could spontaneously bring it to life in a newly initiated living system, would Roy’s consciousness be restored? Would his memories be intact? Would Roy “be there” again? If this were true for Roy, could it be true for us as well? This question takes us into a fundamentally more speculative direction.

Our three assumptions are sufficient to provide a basic level of support for our new cosmological system. The assumption that today’s life experiences may survive in matter’s memory and have an impact, if only emotionally, on future life gives support to the thought that we should care about the quality of today’s life experience because of its potential future influence.

It is not our intention to minimize the importance of caring in the present about the quality of the human condition. We should all be motivated to reduce suffering, increase individual opportunity, and raise the human standard of living in order to provide the greatest good for the greatest number in today’s world. This recognition of future effects from our life experience only increases the urgency of working towards creation of a better life today for all living creatures.

For those readers who enjoy pushing the envelope of imaginative thinking, the following material projects life’s process forward in time and provides what may at first appear to be an unsettling description of a future evolutionary development that may change life as we know it. This possibility has significant implications for how we live our lives in the present and how we think about life’s future.

We have described the process of evolution as a one-to-many-to-one progression. Our simplified view is that one individual has a mutation that creates a new trait that enhances survival under changing circumstances. That individual survives and passes the trait to many individuals through reproduction. In a subsequent generation another of these individuals experiences a new selected mutation which is passed through procreation to many surviving others.

This cyclic path of evolutionary progress contracting to a single individual with a new mutation followed by expansion to many new individuals through reproduction is the way in which life evolves. This process began with a first organism capable of multiplying itself, passing on genetic information with the ability to vary its characteristics over time and evolve into other forms of life. This evolutionary process is repetitive with countless small incremental mutations having occurred over billions of years.

At life’s beginning the first life entity had multiple unique characteristics in addition to being the first mover of the only sustainable life process of which we are aware. At its initiation, it contained all of the sustainable life matter in the universe.

While we have described the evolutionary process for advancing mutated change through natural selection at the individual level, it is possible the process is also at work at an aggregate level. Life began with all life matter concentrated in a single organism. It divided and produced countless generations that followed. At an aggregate level, life’s future evolution may initiate a contraction back to a singular living organism. It will contract to a form containing all of the life matter of the universe. In this way life’s evolution may have a cyclic nature similar to a cyclic universe that some scientists propose, a universe that has undergone a series of implosions or contractions to a point of maximum density and reversals initiating a next sequential big bang.63 Thus, life may expand from a singular organism to many organisms only to again contract to a singular organism.

This possibility of life’s future contraction to a singular organism stimulates the imagination. We can conjure up all sorts of thoughts by imagining the physical shape of this future organism. Our tendency is to think about it in the context of what is familiar. But this would be wrong. This type of thought imposes constraints that must be rejected if we are to be open to the full range of possibilities.

For example, we currently perceive and interpret life as a largely physical phenomenon. Intellectually we know life represents both manifestations of existence, matter and energy. But our predominant perception and area of study has been of our material nature. This may change over time. We can conceive of a future developmental path of an expanded intellect and consciousness with a greater emphasis on energy rather than matter. This is not to predict what is unknowable but rather to open our thoughts to a range of possibilities beyond the present reality. As we think about the future we must set aside the familiar and assume a time when a singular life form may be unique to our experience. It will bear little resemblance to the first single life form or anything we have seen since. It may have neither a physical form nor a scale which is familiar.

We have previously explored the possibility and probabilities of events in the universe. We identified a set of tests to use when evaluating future probability. The probability of life’s future evolution to a single life form once again involving all of the life matter of the universe can be assessed using the tests previously identified. The first test is one of possibility. We observed that in order for an event to be possible it must be consistent with the physical laws of the universe. The ultimate test of possibility is previous occurrence. The evolution of a future singular life form passes this test since the first living organism contained all of the life matter in the universe.

The second test is one of frequency. If an event happens with great frequency, it will have a greater probability of recurrence. The presence of all life matter in a single life form has to our knowledge only happened once in the past. While this does not detract from its possibility in the future, it does not enhance its probability.

The third test to be considered is time, specifically the time allowed for an event to take place. We have asserted the infinity of the universe. This means that, if we assume life’s prolonged survival, there is an unlimited amount of time within which the singular life form can evolve. There is enough time for the evolutionary process to complete a larger aggregate cycle. While this does not insure the future life form will develop, it does increase its probability.

The final test is whether the event is naturally occurring or has an increased likelihood because of human intervention. The evolution of the future singular life form benefits from both possibilities. It can evolve naturally as a result of the evolutionary process and/or it may result from some measure of human intervention. This latter possibility of our intervention may be one of the greatest determinants of future evolutionary development. We are the most unpredictable variable that may affect future events.

For better or worse, we are the wild card that may through our actions determine the ultimate success or failure of life. Our ability to imagine a perfect outcome and then direct our efforts and seize opportunities to realize that outcome is presently unmatched by any other known life form. The probability of a future evolution to a singular life form is significantly increased if we choose it as our ultimate desired outcome.

To extend our speculation should such a life form develop it will be of great significance to every human being since all of life will be a part of it, including each and every one of us. Composed of our aggregate life matter, it will contain the totality of information, knowledge, memory, and experience of each of our individual lives. With the animation and awakening of its consciousness all of us would once again be integrated into a living system and life embodiment. With its awakening, each of us would achieve transcendence beyond the suspended state we call death. Not only would we be integrated into a new single living being that is all of life, we would share its collective identity.

In this sense, the matter of life would be broadly analogous to the material in a magnet. Once magnetized, it has memory of its magnetic state. If one heats a magnet to a high temperature, its magnetism disappears as its individual atoms are so thermally excited that they become randomly oriented and lose the attractive characteristic of magnetism. When the magnetic material cools to below its Curie point however, the atoms spontaneously line up and reestablish their magnetism.

In an analogous way, inanimate matter in the universe becomes involved in the life process. Matter is fundamentally altered by this experience. At death, when the once living matter is no longer a part of a life process and is dispersed into the biogenic sphere, its memory of its participation in life becomes dormant. If this matter is once again incorporated into a living system as was the Tasmanian tiger’s DNA into a mouse embryo, its knowledge of itself and memory of its past life experience is restored. Like a magnet restores its fundamental magnetism, reanimation of life matter revitalizes its dormant knowledge, memory, and experience.

If and when this occurs, our reanimation and awakening would for each of us be instantaneous. In the beginning of this book we described death as the cessation of the life embodiment that contains matter and energizes it to animation. We observed that when the embodiment disintegrates, the matter and energy that constitutes physical existence disperses into the universe. Further, we said that with this disintegration and dispersion, individual consciousness of time and awareness of self cease.

At the moment of each death, awareness of self and the passage of time ceases. With the animation of the future single life form, time for each of us, now integrated once again into a life process, would start anew. No matter how long this evolutionary development takes, how many millions or billions of years will have passed since our individual deaths, for each of us the transition from the moment of our death to our reanimated life would be instantaneous. In this sense, if and when it occurs, from our individual and personal perspective we will instantly reawaken from death.

The final significance of this future life form would be that it would represent only the second opportunity for life to experience existence having many of the characteristics formerly defined and reserved for the supernatural existence of God. These characteristics are Omnipresence, Omniscience and Omnipotence. The perception and consciousness of time, the acquisition and understanding of knowledge and the willful exercise of power are exclusively life attributes. This life form would have the totality of the life experience. As such it would have all perception and consciousness of time, the totality of life’s knowledge, and would be the only entity in the universe to consciously exercise free will and power.

The possibility and potential of such a development raises questions about its initiation and our possible experience of it. There are several things we know. The first is that if it happens it will be in the distant future and we, as living individuals, will not be there to experience its transition. We will however, join its awakening. As it was with the first initiation of life, while it is tempting to imagine the awakening as an event occurring in an instant, it will most likely be the culmination of a long process of development and awakening. Let us remember that self recognition in human infants occurs after 18 months of life. Presumably this future life form will have similar developmental phases it must pass through before it achieves its full self awareness.

As it was the first time, there will be a requirement for a specific set of circumstances with a necessary amount of life material for it to happen. We know the life material necessary for its awakening is growing in the biogenic sphere, that thin layer of living and once living matter that encircles the planet and is imprisoned in its gravitational field. Each succeeding generation of all of life’s species contributes its life mass to the aggregate life matter surrounding our planet. We can imagine that the process may be analogous to the initiation of a self sustaining chain reaction that occurs when a critical mass of fissionable material is in place for a nuclear explosion. There may be a threshold critical mass of life matter that must be reached in order for the aggregate evolutionary cycle to complete. We know the evolutionary process is at work. We do not know its stage of development or nearness to completion. Because we will be integrated into this new entity we will know if and when a future single life form achieves consciousness.

We can only speculate about what we individually will experience if and when it comes into existence. It will be a sentient living being. It will obviously benefit from the consciousness contributed by the experience of higher life forms which include human beings. It will represent life’s most advanced, evolved state. It will have self awareness and an identity. It will have intellect and personality. It will have feeling and emotion. It will have the total knowledge and memory of each of our individual life experiences.

We must look at how we exist now to gain insight into what it may be like to be a part of this new entity. We know our lives are not static. We have trillions of cells in each of our bodies. These cells are active during each instant of our existence. There are approximately 100 billion neurons or nerve cells in the human brain. These cells and neurons elsewhere in the body are continuously receiving and sending impulses from and to other parts of our bodies and the environment. With the average world life span of a human being at about sixty-six years we have 24,090 days of existence. Each day we record a different set of thoughts and experiences. Each day some of our cells divide and some of them die. It is as if we are a new person each day.

Yet, while we are new each day, we are also the person we have been in all of our previous days. We are a composite of who we have been at each instant of our existence. Just as the person we were yesterday no longer exists but in our consciousness of ourselves today, we as individuals as a part of a future single life form will exist in its consciousness of itself in all of its previous lives. Its memory of us however, may be even more acute and vibrant for while we lose cells and matter from our bodies throughout our lifetime, it will have all of our matter within its embodiment. For this reason it may know us more than we know ourselves.

Every cosmological and philosophical system has implications about what people should and should not do in their lives. Some of these implications assume the force of imperatives in that certain actions are absolutely required by the belief system. Implications and imperatives are about positive outcomes and negative consequences. Action in accordance with beliefs has positive outcomes and failure to act in accordance with them creates negative consequences. A belief system which does not or cannot serve as the basis of behavior loses its justification. In evaluating a belief system, its implications and imperatives are as important as the original beliefs.

The direction and form of evolution in the future by definition involves distant events. At this point these events are nothing more than desirable potentialities. We have limited knowledge of what must take place for them to become a reality. We can, however, define the broad outlines of four major implications for us which assume the stature of imperatives when we decide to accept and pursue the course of evolution we have identified. These four imperatives must be satisfied if our chosen path of evolution is to be fulfilled.

The four imperatives are that:

  • life’s evolution must continue,
  • life’s collective experience must have a preponderance of positive experiences,
  • life must be protected from threats,
  • human beings must intervene in the course of events and insure the achievement of the first three imperatives.

The future developments we’ve identified will represent significant thresholds of life’s evolution. The only future that matters in an inanimate universe is the future of life. Evolution is the most dynamic and important of life’s processes. Without life, all that happens in the universe is irrelevant. The first imperative is that life’s evolution must continue. As discussed in Chapter 6, life’s consciousness must evolve to the highest state of awareness possible.

Future life will have access to the collective life experience that has gone before. Its view of reality will reflect the positive and negative influences of those past life experiences.

The second imperative is that the collective life knowledge and memory must have a preponderance of positive experience to counteract negative influences. This will insure the future single life form will have a positive and optimistic outlook on reality.

Without definitive knowledge of the timing of evolutionary development, our reintegration into a living system could occur at any time in an infinite future. The third imperative is that life must be protected so it has sufficient time for its evolution to continue and complete. If our universal life is allowed to disappear, it is probable that no future evolution will take place.

Life must continue if it is to fulfill its potential. There are a series of threats looming over humanity that must be addressed to assure life’s continuance. These include the ozone hole, global climate change, nuclear weapons, and synthetic biology.

The fourth imperative is that the achievement of the first three imperatives requires human intervention and direction. We individually and collectively have a choice to make. We must choose the possible evolution of which we can conceive as our preferred outcome and dedicate our efforts to its achievement, fully accepting responsibility for the other three imperatives.

In the final analysis, those seeking a new cosmological and philosophical alternative have previously been skeptical of earlier belief systems. Their skepticism has driven them to keep looking and yet doing so will also keep them from unconditional acceptance of a new alternative. Understanding that there is always uncertainty associated with potential future events, skepticism is well founded. We cannot ask that anyone believe without reservation in the future evolution of a singular life form. We can ask however that they choose to believe with reservation. While this may seem too fine a distinction and an insignificant caveat, the choice to believe preserves the freedom to be skeptical while allowing action as if certainty has occurred.

 

CHAPTER 9 


A Positive Life Experience Imperative

As time passes, life and its evolution continue to grow the experience and emotion that is available to all manner of future life forms. We have spent considerable time assessing human uniqueness and evolution. As we are the greatest beneficiaries of evolutionary development of intellect, emotion, and consciousness, these traits will provide the greatest human contribution to the attitudes, opinions and sensitivities of a future life form. They will be a key determinant of its intellect, knowledge, emotions – especially higher order emotions informed by intellect – and its consciousness.

Just as life experiences shape our personalities by creating feelings of optimism or pessimism, self confidence or insecurity and hope or despair, so will our experiences affect future life. The question we must then ask is what will be our net contribution? Will we be a net positive or negative influence? Where are we starting from and what must we do in the future? We need to have a way of thinking about positive versus negative contributions and some form of yardstick with which to measure progress.

We find such a measure in the work of psychologist Abraham Maslow who was influential in personality theory. Maslow perceived a Hierarchy of Needs that determined the priorities of behavior in animals and human beings.64

He observed certain needs took precedence over others and only when they were addressed could an individual turn his or her attention to a higher order of need. For example, if a person is hungry and thirsty, satisfying thirst takes precedence over hunger. The reason is basic to life. While we can survive for a few weeks without food, we can only remain alive for a few days without water. By the same token, if something were to cut off our air supply, we would immediately put aside hunger and thirst in order to restore our breathing. In this hierarchy air, water, and food are three essential needs in Maslow’s most basic category of needs. He called them the Physiological Needs.

Maslow’s Hierarchy of Needs was broken into five categories depicted in a pyramid structure. He assumed all human beings are born with these needs and that only once they have satisfied the more basic needs at the bottom of the pyramid, can they focus their attention on other needs. The levels of his Hierarchy of Needs are summarized as follows:

Physiological Needs:These are biological needs including needs for oxygen, food, water, and a stable and comfortable body temperature. They come first among all other needs because they are essential to all life. This basic category includes the need for activity, rest, sleep, to avoid pain, and have sex. Physiological needs are the first of four levels he saw as Deficit Needs. He defined these levels as consisting of things that when you do not have enough of them you have a deficit and you feel a need to fill the deficit. Conversely, once you have enough or have satisfied these basic needs they no longer motivate you.

Safety Needs:After physiological needs are met needs for safety become prominent. Adults are generally unaware of security needs except when perceiving threat. Children feel the need to be safe more often than adults. This can include an individual’s need for safe and stable circumstances, protection from perceived threats, and structure and order in one’s life. It can also be the need to counteract feelings of anxiety and fear by having a good job, savings in the bank, insurance, etc.

Needs of Love, Affection and Belongingness:When needs for safety and physiological well-being are taken care of, needs for love and belonging emerge. Maslow mentions feelings of loneliness and alienation but this category also includes giving and receiving love, affection and the sense of belonging. This need for a sense of belonging is when you feel the need for family, friends, and affectionate relationships in general.

Needs for Esteem: When the previous classes of needs are met, needs for esteem surface. These include self-esteem and the esteem one perceives from others. Maslow cites two tiers. A lower tier is other directed and includes a need for status, recognition, reputation, and fame. A higher tier is self directed and manifests needs for self-respect, confidence, achievement, mastery, independence, and freedom. The latter needs are in a higher tier because once you have satisfied them, they are harder to lose.

Maslow sees the first four levels of his pyramid of needs as survival needs. In his view even belongingness and esteem are essential to health. According to Maslow all of these needs are built into human beings genetically. He believed the fulfillment of them is instinctive. He used the term homeostasis to describe the state we are seeking in our lives or a stable state of equilibrium and balance where all of the survival needs are reasonably met and we no longer have to think about them. He also recognized that when survival is threatened people can regress to lower level needs. Even successful people feel threatened in periods of economic downturn and they regress and focus on lower level needs.

Needs for Self-Actualization: When all other needs are satisfied needs for self-actualization emerge. Unlike survival needs, Maslow referred to this category as consisting of growth or being needs. He believedthat once these needs are engaged they do not shut off like survival needs. The need for self-actualization continues and even grows stronger as the individual begins to satisfy it. He referred to self-actualization as a person doing what they were “born to do.” This is when people are most creative and productive and have a sense they are achieving at their full potential.

For further definition of self-actualization Maslow studied a group of high achieving individuals. He used a qualitative method called biographical analysis to identify characteristics indicative of self-actualization. In addition to 12 unnamed people he knew whom he felt were self-actualizers, he studied John Adams, Albert Einstein, Alduous Huxley, William James, Thomas Jefferson, Abraham Lincoln, Eleanor Roosevelt, Albert Schweitzer, and Benedict Spinoza.

He identified a list of qualities that were characteristic of the people studied and offered them as indicative of self-actualized people. These included a need to be reality-centered, problem-centered, to have a perception of difference between ends and means, have a sense of humor that is not hostile, humility and respect for others, strong ethics, human kinship, and creativity. In addition, he identified special driving needs of self-actualizers. These are needs that have a profound effect on behavior. These included a need for truth, goodness, beauty, uniqueness, completion, justice and order, simplicity, playfulness, self-sufficiency, and meaningfulness.

Maslow recognized that in order to be self-actualizing the individual has to have all of their lower needs taken care of to a considerable degree. He reasoned that if you are hungry you will be looking for food. If you feel your safety is threatened you will be on your guard. If you are lonely and isolated you will be trying to make friends. If you have low self-esteem you will be defensive. In other words, if any of the lower needs are not significantly met, you will not be able to be fully self-actualizing or trying to realize your potential.

Maslow felt that given how difficult life is in the modern world only a small percentage of the world’s population was truly able to spend most of their time being self-actualizing. Maslow at one time estimated this percentage of the world’s population at two percent. This observation serves as a basis on which Maslow’s Hierarchy of Needs can be useful in our investigation.

We will not take Maslow’s Hierarchy of Needs too literally. We recognize that individuals respond to needs as they perceive them and not necessarily in the order in which Maslow identifies them. We will accept his broad premise that lower order needs for survival typically take precedence over every higher order need as well as the more intellectual, being needs. We will use his construct as a way of evaluating whether net positive or net negative experiences contribute to the aggregate human life experience.

If we assume, as Maslow did, that overall success in life will satisfy survival needs along with achieving self-actualization, we can look at selected world economic criteria as indicative of the continuum of the human condition. We will look at per capita income and household wealth of the world’s population. We will assume people in poverty and those with limited means spend most of their time trying to fill their survival needs and that those with higher incomes and wealth have a greater likelihood of being self-actualizing. This should give us a broad yardstick to measure our balance of positive and negative life experience. We will further assume that people living exclusively in their survival needs have a net negative life experience and people who are self-actualizing have a net positive life experience.

A study entitled, The World Distribution of Income: Falling Poverty and . . .Convergence, Period*, written by Xavier Sala-i-Martin, Professor of Economics at Columbia University, and published in the May 2006 issue of The Quarterly Journal of Economics defines the World poverty line as income that is less than $3 (US$) per day or $1,140 per year.65 This conclusion is supported by Chen and Ravallion (2004) of the World Bank who reconcile the World Bank’s use of $1 worth of daily consumption with Sala-I-Martin’s $3 of daily income. Shaohua Chen is a Senior Statistician in the Development Economics Research Group of the World Bank and works for Martin Ravallion who is the Director of the Development Research Group. All three agree, that of the World’s roughly 5.6 billion people in 2000 for which we have data, 1.2 billion, or just over 21% of them had income that fell below the World poverty line.

Another useful measure with which to look at the World’s population in terms of freedom from survival needs is household wealth. Household wealth is defined as net worth or the value of physical and financial assets less liabilities. The assumption holds that households with accumulated wealth are less subject to adverse events which may negatively affect income such as ill health or unemployment since they have built up a financial cushion to help them through tough times. Accordingly they are less likely to worry about survival needs and should therefore be more self-actualizing. For this look at the human condition we use data from a paper entitled, The World distribution of Household Wealth published in 2008 by the United Nations University World Institute for Development Economics Research.66 The findings of this study and the previously mentioned income study are summarized in the previous table.

The report states, “According to our estimates, adults required just $2,138 in order to be among the wealthiest half of the world. But more than $61,000 was needed to belong to the top 10 per cent and more than $510,000 per adult was required for membership of the top 1 per cent. The entrance fee for the top 1 per cent seems surprisingly high given the group has 37 million adult members. Furthermore, the figure refers to the year 2000 and is now likely to be considerably higher, especially when measured in US dollars.” The report continued, “The wealth share estimates reveal that the richest 2 per cent of adult individuals own more than half of all global wealth, with the richest 1 per cent alone accounting for 40 per cent of global assets. In contrast, the bottom half of wealth holders together hold barely 1 per cent of global wealth.”

These statistics paint a discouraging picture of the world’s distribution of income and wealth. More disturbingly, using the Hierarchy of Needs, these statistics imply a majority of the World’s population is primarily engaged in satisfying survival needs and has very limited opportunity for self-actualization.

Data from past studies show that even though much progress remains to be made, the trends are encouraging. For example, poverty rates measured by the $3 per day poverty line have declined significantly since 1970 when it was estimated that over 46% of the world’s population income fell below this level. The 21% of the adult population with less than $3 of income per day in 2000 is low by comparison and represents better than a 50% reduction of the world poverty level in the last 30 years. Significant progress has been made especially in some of the world’s most populous and poorest countries. For example China in the last decade has lifted hundreds of millions of Chinese above this poverty line.

While the trend lines are positive and show a steady decrease in the world’s poor, we know these positive trends are threatened by economic downturns and the looming specter of climate change. Worldwide food shortages and the forecasted significant rise in the Earth’s average temperatures threaten the improving state of well being. The gravest threats posed by global climate change are in the very regions of the world that have the greatest poverty. These regions include Africa, Asia-Pacific (excluding selected wealthy Asian countries), India and Latin America. They all possess the least resources with which to withstand the negative effect of rising world temperatures on agriculture and the availability of fresh water (see Chapter 11 on global climate change).

It is estimated that climate change will put almost 50 million additional people at risk of hunger by the year 2020. By that year agricultural output in developing countries is projected to decline by 20 percent with, for example, land suitable for wheat production becoming almost non-existent in Africa by the year 2080.

While short term trends may be turning positive only to be slowed by a worldwide economic crisis, the long term macro trends offer some hope. Since records have been kept humanity has had a steady march toward a more positive state of the human condition. Poverty rates have declined, medical care has improved, life expectancy has increased and in innumerable ways human beings are better off today than their forebears. The human condition has improved to such an extent that many now believe it is possible for human beings to dramatically reduce world hunger and raise the collective standard of living to reduce poverty to a manageable level.

Of greatest significance is that the steady march towards a higher state of world prosperity is no accident. A conscious movement has emerged among the world’s wealthiest countries to attack world problems of hunger, poverty, and disease. That beneficial view is held by the forward thinking citizens of those countries. Representative of this trend is the United Nations General Assembly’s adoption of eight Millennium Development Goals in 2000 for world progress by the year 2015.67 These goals, each of which has specific objectives associated with them, are broadly identified as follows:

  1. Eradicate extreme poverty and hunger
  2. Achieve universal primary education
  3. Promote gender equality and empower women
  4. Reduce child mortality
  5. Improve maternal health
  6. Combat HIV/AIDS, malaria and other diseases
  7. Ensure environmental sustainability
  8. Develop a global partnership for development

To underscore their commitment to the achievement of these goals the developed nations of the world pledged .7 percent of their gross national income (GNI) to development aid in support of these Millennium Development Goals. As of 2007 only five of the world’s developed governments had met or exceeded the .7 percent GNI donation threshold, Denmark, Luxembourg, the Netherlands, Norway and Sweden.68 Many of the identified goals will not be achieved. Critics will point to the small amount of money that has been committed, the developed world’s failure to fund even at a low level of commitment, and the present worldwide economic downturn. Nevertheless, the identification of these objectives and imagination of a world that has solved these problems is truly historic. It represents one of the highest states of human consciousness and one of the most profound levels of human aspiration.

This aspiration is a landmark in human history. It represents an unprecedented level of optimism about the progress which humanity could achieve. It is important because of the opportunity it presents to ultimately create a net balance of positive over negative life experience. We can now imagine a world where the majority of people have survival needs largely met, poverty, hunger and disease are controlled and most human lives contribute positively to the collective life experience.

In the first chapter of this book we identified questions people ask when thinking about life and death. Those questions included “Do we somehow determine our fate in death with our actions in life? Are different afterlife outcomes dependent on how we live our lives?” We now have the new context of our contribution to future life in which to think about these questions. We perceive a forthcoming life form as a natural culmination of the evolutionary process. It represents for each of us another opportunity to be in a life process where we bring to this future existence all of the experiences and identity of our first life. We know this future existence will be different from the former in that we will all experience it together. This creates a new dependency.

While our first life experience was largely individual and singular, the future will be shared and collective. As a net positive or net negative existence, it will be dependent on the aggregate life experiences that are brought to it. We know in a present human history filled with hunger, poverty and disease, the collective human contribution will be negative. We also know we can change this outcome. We can commit ourselves to the elimination of poverty and hunger, the reduction of disease and can over time create an opportunity for progressively increasing numbers of self actualized lives. With a long term sustained commitment and effort we can insure a future collective existence where net positive experiences overwhelm negative influences.

As humans we must recognize our shared community and the interdependence of our future well being. We must accept individual responsibility for our collective future. An enlightened few amongst us must decide to alter the course of the many to create a world where all people rise above the tyranny of day-to-day survival and experience self-actualization. Only in this world can evolution progress to where each person has an opportunity to contribute to the larger life awareness and where each life makes a positive contribution to the future collective consciousness.

Beyond Animal, Ego, Time: Chap 4: Uncertainty, Probability & Life – Chap 5: Life’s Knowledge & Memory – Chap 6: Human Uniqueness

Posted on 04 March 2013 by Jerry

I’ve decided to serialize my book on this website.  As an incentive to readers to return to the site, each month I will post at least one Chapter of the book until the entire book is posted.  Go into the Archives to “Beyond Aniimal” for earlier chapters.  The book provides context for the blog, clearly explaining the underlying philosophy and identifying critical issues of our time.  –

CHAPTER 4 

Uncertainty, Probability and Life –

For generations there has been debate about whether the universe is a deterministic system or if there is an uncertainty that permits human choice and free will. Early atomists articulated a theory that all processes in the world were due to mechanical interactions of atoms. Newtonian physics depicted physical matter as acting according to a set of fixed and knowable physical laws. This “billiard ball” hypothesis assumed that once the laws and initial state of the universe were established, the future of the universe would follow predictably and inevitably just as the precise direction, momentum, and distance can be calculated to predict the reaction of one billiard ball struck by another on a pool table.

Presumably, with complete knowledge of the matter of the universe, its laws, and starting point, it would be possible to predict the time and place of every event that would ever occur. With this view, uncertainty would occur only with inadequate knowledge of all influencing laws and factors. Under this view even human behavior would be predictable. Imagine how boring existence would be if this had been true, if with enough information you could predict all future occurrences including human behavior.

Fortunately the study of light and the eventual articulation of quantum mechanics have disproved a deterministic universe essentially affirming life’s freedom to choose. What began as a debate over whether light was a particle or wave phenomenon became a historic realization that light had both characteristics, those of particles and waves depending upon how one studied it.

The following list of experiments and evolution of insight about the nature of light have been the subject of numerous books. Because of the complexity of the issues and various interpretations over the years, we will not provide more than a high level listing of key scientific contributions that proved critical to the present understanding of the particle and wave duality of light and its contribution to the Heisenberg’s Uncertainty Principle.

The historic debate began in the 1600s when Christiaan Huygens, a Dutch mathematician and physicist, and Isaac Newton, an English mathematician and physicist, proposed differing, competing theories about the nature of light. Newton’s view, that light was composed of particles, predominated for two hundred years until the wave-like nature of light was demonstrated in Thomas Young’s double slit experiments. Young was an eighteenth century English genius and acknowledged polymath. In his experiments light was passed through two parallel slits on a plate where the light hitting a screen behind the slits showed characteristic interference patterns, light and dark bands, where the light waves interfered with each other. These experiments revived thoughts of light as a wave phenomenon.

Einstein however, in the early 1900’s, found it difficult to explain the photoelectric effect with a wave theory of light. He demonstrated that light possessed particle-like properties or photons with sufficient energy to dislodge electrons from metals and non metallic solids, liquids or gases. He was awarded a Nobel Prize for his work.

Niels Bohr, a Danish physicist, found it impossible to adequately describe all of the properties of light solely using either the wave or particle analogies. To overcome this difficulty he developed a principle of complementarity which is a theory of pairs, such as the pairing of wave and particle or the pairing of position and momentum. His principle held that items could be separately analyzed as having several contradictory properties. Louis de Broglie, a French physicist, worked out the mathematical consequences of this principle which served as the basis of his discovery of the theory of wave-particle duality in 1924 that states that waves and particles have properties of both at the same time.

These developments were followed in 1925 by Werner Heisenberg’s development of his quantum mechanical theory. Heisenberg, a German theoretical physicist, was working on a hypothesis that said that electrons emit characteristic photons of light when moving from one orbit farther from the nucleus of an atom to another orbit nearer to the nucleus. A photon particle is the basic unit of light and all other electromagnetic radiation. In this particle-like view of an oscillating charged electron, particles would quantum jump from one orbit to another consistent with energy, described by Planck’s constant, delivered as packets along the wave.

Later in 1925, Edwin Schrödinger, an Austrian theoretical physicist, analyzed what an electron would look like as a wave around the nucleus of an atom. An electron is a subatomic particle which carries a negative electric charge and with no known components of substructure is believed to be an elementary particle. He came up with a wave equation that describes each electron as having a wave function. He thus showed that the atom was not at all like a miniature solar system, but that the electron in a hydrogen atom was more like a wave that covered the entire sphere of its orbital all at once, meaning it was three-dimensional.

In 1927 Heisenberg made a new discovery which has been variously called the Heisenberg Indeterminacy Principle or Heisenberg’s Uncertainty Principle. He demonstrated mathematically that when a moving particle is viewed as a wave it is less certain where the physical particle is located. In fact, the more certain one knows a particle’s position, the less certain its momentum is known. His conclusion was that one could be precise when measuring the position of a particle and could be precise when measuring its momentum but there is an inverse imprecision when attempting to measure both at the same time. Put another way, classical Newtonian physics said that if you knew the position of stars and planets and details about their motions you could predict where they would be in the future. For subatomic particles, Heisenberg asserted that due to his uncertainty principle one cannot know the precise position and momentum of a particle at a given instant and consequently its future motion cannot be determined. One can describe only a range of possible future motions of the particle.

Albert Einstein did not accept Heisenberg’s Uncertainty Principle leading to his famous statement that, “God does not play dice”.16 Einstein rejected a probabilistic universe continuing to believe you could predict the future location of a particle. He attempted to disprove the Uncertainty Principle by focusing on one consequence of quantum theory that he called “action at a distance”. He showed that quantum mechanics predicted an “entanglement” between some particles. This entanglement meant that when there is a change in one entangled particle at a distance from another, the other entangled particle changes to counter-balance the system of the particles that are entangled.

In quantum entanglement, measuring one entangled particle defines its properties and seems to influence the properties of its partner or partners instantaneously no matter how far apart they are. Due to the entanglement, interaction on the one causes instantaneous effects on the other. While seeking to discredit quantum mechanics by demonstrating this required entanglement, Einstein instead forced advocates of quantum mechanics to acknowledge entanglement as a fundamental principle. Particle entanglement was subsequently verified experimentally.

The theory of quantum mechanics was developed to explain the counterintuitive experimental results showing simultaneous particle and wave characteristics of subatomic matter. Each of the scientists who contributed the foregoing experiments and conclusions contributed to the conceptual framework and mathematical proofs necessary to establish the credibility and predictability of quantum mechanics. Quantum mechanics is now the body of scientific principles that describe the behavior of matter and its interactions at the atomic and subatomic levels.

The uncertainty of position and momentum of matter at the subatomic level refutes a deterministic universe. It describes a fundamental unpredictability. It indicates that every subatomic event is subject to a distribution of probabilities. It transforms our view of future events to a set of probabilities with numerous potential outcomes. Uncertainty is real at the subatomic level but is most apparent in the unpredictability of the behavior of living organisms, unpredictability that increases with the complexity and awareness of the organism.

Human beings when making conscious decisions utilize matter’s uncertainty and indeterminism to allow them to exercise free will. Uncertainty at the subatomic level underlies the unpredictability of human behavior. It also reinforces our use of probability when thinking about future events.

The mathematics of probability is well understood. We know how to identify the likelihood of random physical phenomena which are predictable in principle when there is sufficient information and when the phenomena are essentially unpredictable. These types of events include the probabilities of achieving a specific outcome when spinning a roulette wheel or tossing dice. It is possible to identify the probability of red coming up in a spin when playing roulette. Further, one can calculate the probability of getting two reds in a row, ten reds in a row or a million reds in a row. The theory is that since it is possible to experience a string of reds in a row, the repetition a specific number of times can and will happen if you have a sufficient number of spins to allow the probability to occur. Of course, the longer the string of reds that is being predicted the smaller the probability and the longer the time required. Most would say that given an infinite amount of time, theoretically any length of string of reds will eventually happen.

When evaluating the future probability of an event there are a few tests which can be used. The first test concerns possibility. Is the future event consistent with what is possible given the rules in the universe? Obviously, if an event has already happened, it is possible that it will happen again in the future.

The second test is to identify the past frequency of the event. If the event occurs with great regularity, this will have an obvious impact on the assessment of its probability. If an event or string of events is possible and one has a sense of its present frequency of occurrence, then the probability of the event can be computed relatively easily.

The third test to be considered is time. The computation of probabilities will be largely dependent upon the time allowed within which the event can happen. Also obviously, if the scale of time being considered is infinite, the probability of an event happening significantly increases but still may not be certain.

The fourth test is whether the anticipated event is naturally occurring or can only happen with the intervention or direction of a conscious life form. To elaborate on this last test, let’s go back to our example of a roulette wheel that produces a long string of reds in a row. We know roulette wheels are a product of human gambling. If our existence was infinite and we chose to construct many more roulette wheels to consciously try to achieve a million reds in a row, the odds of its occurrence would certainly increase.

On the other hand life on our planet is fragile. There is a meteor crater in the Wilkes Land region of East Antarctica that is approximately 300 miles wide. The meteor that made this crater was 30 or so miles wide. This meteor is credited by many scientists with the largest mass extinction of life that we see in the Earth’s geologic history, the Permian-Triassic extinction that set the stage for the age of the dinosaurs. Another crater in the Yucatan peninsula in Mexico, the Chicxulub crater, is credited with the mass extinction of the dinosaurs setting the stage for the emergence of the next dominant species, mammals, which of course includes Homo sapiens.

It is clear our planet can be hit by a large meteor that can have a disastrous effect on life. Such an event could kill Homo sapiens ushering in a new life form’s ascendancy or could destroy life on our planet entirely. Should either happen, the likely fabrication of more roulette wheels to create a million red outcomes becomes infinitesimal. In this case the likelihood of an event is dependent upon the intervention and direction of the life form that has produced roulette wheels. The achievement of a million consecutive red spin outcomes might only happen if humanity decided it was important, focused its will on making it happen, and had a long enough life span to accomplish it. This would clearly be a case of life applying direction and intervention to consciously enhance the probability of an outcome.

Many have speculated about the existence of other life in the universe. They see the large, if not infinite, number of galaxies, solar systems and planets, and the known initiation of life in our solar system. They therefore assume that life is highly probable elsewhere in the universe. This has served as the justification for speculation about how we might encounter extra-terrestrial life in science fiction works such as War of the Worlds, ET, and Star Wars. It is responsible for the continuing series of sightings of unexplained atmospheric phenomena and recurring urban myth stories of alien capture and imprisonment. It has also served as the basis for serious efforts to discern the existence of life elsewhere, e.g. SETI (Search for Extra-terrestrial Intelligence).17

In 1959 two physicists at Cornell University, Giuseppi Cocconi and Philip Morrison, published a paper indicating the suitability of using microwave radio to communicate between the stars. Another radio astronomer, Frank Drake, independently reached the same conclusion and in 1960 used an 85-foot West Virginia microwave antenna pointed in the direction of two nearby solar systems to listen for signs of life. This launched a variety of projects in the old Soviet Union, at NASA’s Ames Research Center, at the Planetary Society, University of California, and Jet Propulsion Laboratory. All spent countless hours listening to the universe for signs of other intelligent life. No scientifically verifiable emanation from an extra-terrestrial life form has yet been received.

Beyond listening for signs of life, we have visited other objects in our solar system either in manned probes such as the trips to the moon or with unmanned probes to planets, moons, comets and asteroids. At this point we have visited virtually all of the planets in our solar system. While we have found or hypothesized conditions elsewhere which may be necessary for the initiation of life including atmosphere, organic chemicals, and water and ice, they are insufficient to produce life. To date, we have not found evidence of life that has been scientifically established or verified.

Nevertheless many people continue to believe the probability of finding life elsewhere is quite high. There are two ways of looking at the probabilities of the initiation of life however. One way is to argue that a potentially infinite number of planets provide almost certain probabilities of life occurring elsewhere. Or it can be argued an infinite sequence of specific events and conditions had to occur precisely as they did to initiate sustainable life in our solar system. This argument holds that the likelihood of a similar sequence and conditions repeating themselves to produce a comparable outcome is improbable if not impossible.

The consequence of these two competing views of the probability of life elsewhere is that we end up pitting one infinite circumstance against an infinite sequence of specific events and conditions. One of these circumstances argues forcefully for the probability of life elsewhere while the other argues equally forcefully for its unlikelihood.

This being the case, there is still the practical question of whether we will we ever know if life exists elsewhere? An analysis of the likelihood of ever discovering, or even more unlikely, making contact with other life leads to the conclusion that we must live as if we are alone, because for all practical purposes we are alone.

The math of our practical isolation is as follows. If we assume we will not find life in our solar system – and so far it seems that we will not – we will have to look to the closest star to our sun which is Proxima Centauri (or Alpha Centauri C) in the Alpha Centauri System. It is estimated to be 4.22 light years from our sun.18A light year represents the distance light can travel in a year’s time. Light travels at 186,000 miles per second. With over 31,500,000 seconds in a year, the distance in one light year is about 5.8 trillion miles. The distance in 4.2 light years represents approximately 24 trillion miles.

The fastest human space craft, the Helios probe of the sun, is believed to have reached the speed of 150,000 miles per hour at its closest approach to the sun.19 This speed was achieved by the acceleration gained from the gravitational pull of the sun as the probe passed. At that speed, traveling the distance of 24 trillion miles to Proxima Centauri would take over 18,000 years. And this is to reach a sun which it is doubtful can support life since it is a red dwarf, that is a flare star with random increases in brightness due to magnetic activity. In addition it may not have any planets in orbit. Putting 18,000 years in context, it is nine times the amount of time that has passed since the birth of Christ.

Because there is no tangible demonstration of extraterrestrial life, we should act as if ours is the only surviving and sustainable life in the universe. It should be reiterated that while the initiation of life is of continuing interest, it is the establishment of sustainable life that has the greatest significance. It is the continued existence of life on this planet spanning billions of years in an unbroken chain from a first sustainable life form that makes Earth’s situation unique and its duplication all the more improbable.

CHAPTER 5 

Life’s Knowledge and Memory

We know living matter has memory. Human beings are living matter and have memory. The most basic example is our ability to access the stored information in our memory, recalling it at will for use in our everyday lives. Consider all the faces you’ve seen on television and in movies, people you’ve seen on the street and ones you’ve met. Think of the tens of thousands of faces to which you have been exposed. Is it not a marvel that you can remember, can isolate and recall out of all those faces in a lifetime a specific person you’ve met, remembering not only their face but often their name and the situation in which they were encountered?   It is almost magical that from all the moments we’ve experienced, we can recall a specific person who we encountered in a few minutes at a specific point in our life.

We can demonstrate matter has memory in a different way by considering all of the information contained in a single living cell. All living cells contain genetic material or DNA. These cells, from bacteria to human beings, contain one or more sets of basic DNA complement that is unique to the species. This fundamental complement of DNA is a genome. The genome may be subdivided into chromosomes, each of which is a long single continuous DNA molecule. In its turn a chromosome can be identified as composed of thousands of functional regions called genes, and also into regions of less well understood function.

Consider the human being. Each human body is composed of trillions of cells. Each cell has 46 chromosomes in two equivalent sets, or genomes, of 23. Each of the chromosomes is unique and is matched only by its corresponding partner in the other set within that human cell. It is similar to a chromosome in all other human beings.20 When the Human Genome Project, to map and sequence the human genome, was “completed” on April 14, 2003, scientists had identified about three billion base pairs of genes consisting of roughly 20,000 individual genes.

This represents a significant amount of information stored within the chromosomes of a single living human cell. It represents knowledge of the basic chemistry of life which is at work in all cells of living organisms. Shared by all living things, this common chemistry endows each living cell with the knowledge of how to organize the material around it into chemical reactions that support and sustain life. All living entities share this knowledge of how to turn inanimate matter into living matter. For our purposes we will use the terms information, memory, and knowledge interchangeably to represent information that is contained or stored in living or once living tissue that can be recalled to describe or construct a unique living individual or represent its specific life experience.

Now consider more fully this memory of a specific face or past experiences in our lifetime. We know the phenomenon of memory takes place at a person’s perceptual level. We know individuals have memory. We also know individuals are composed of constituent matter and energy. The memory we perceive necessarily involves matter at levels below the person’s perceptual level. It involves cells, constituent molecules, atoms, particles, etc. As a consequence we know underlying processes are taking place at multiple levels of material magnitude. How information, our experiences, and memories, are etched on our matter and at what levels of magnitude, is beyond our present scientific understanding.

A remarkable example of storage of information which may be analogous to our situation is the hologram. Generally, to create a hologram, coherent light from a laser is split into two beams. One beam, called the object beam, is reflected onto the object to be viewed. As this beam hits the object, a pattern of light is captured on a photographic medium. At the same time, the other beam, called the reference beam, is directed past the object with its light hitting the photographic medium from a different angle. These beams converge on the photographic medium from different directions to produce an interference pattern containing both intensity and phase information about the object. This makes it possible to reconstruct the object’s image with a laser or white light. The interference pattern and image on the photographic medium is called a hologram.

These recorded interference patterns give a range of information that enables us to view the recorded image as if it were three dimensional. It is as if we can view the image from different perspectives, actually allowing us to see it from different sides. In addition, if we view the image as projected by coherent light, it leaps off the photographic medium and appears to float in space. With some holograms, if the photographic plate is broken into smaller pieces, each piece retains a miniature representation of the entire image from a specific perspective.

In an analogous way energy waves that impact our body and its sensory system – whether light, heat, sound, or electrical impulses from different sources – may create the equivalent of multiple layers of interference patterns that cause cells and the matter they contain to record and store the information of our experience. Once stored, we can later call forth this information from our memory. In a real sense, the memory of living matter may be like that fractured hologram where each piece bears in miniature the complete image of the object of the hologram.

While there is no need to speculate about the memory of matter in a living organism, for matter that was once living the reality of surviving information, knowledge, and memory is less obvious. It is through study of the DNA of long extinct life forms that we have evidence that information and memory from the life process and a living individual survives outside a living state. For example, the study of fossil DNA provides proof that life’s knowledge and memory survives the death of its organism.21

The first successful extraction of DNA from the remains of an extinct animal took place in 1984. DNA was extracted from the remains of a quagga, an extinct species that looked like a cross between a zebra and a horse. This was accomplished by Allan Wilson of the University of California (UC) Berkeley. It was quickly followed by extraction of genetic material from a mummy that was 2400 years old. This was accomplished by Svante Pääbo, then a paleogeneticist at the Max Planck Institute for Evolutionary Anthropology in Leipzig, Germany. Since these first experiments, scientists have now extracted and deciphered DNA from numerous extinct species including moas, a flightless bird from New Zealand, Tasmanian tigers, mammoths and mastodons, ground sloths, cave bears, and Neanderthals. By 2004 DNA of some 50 ancient species had been studied.22

When an animal dies its tissues quickly fall victim to a number of attackers including insects, bacteria and fungi. These organisms and single-celled microbes use the tissues as a source of nutrients. As a result, DNA, at least with present methods and knowledge, is no longer identifiable. Some fragments of bone, teeth and even fossilized animal droppings however, can endure this onslaught and produce decipherable DNA fragments. Conventional scientific wisdom until recently told us that the outer limit of DNA’s survivability was 100,000 years. Genetic material dating as far back as 800,000 years ago can be retrieved from small samples of soil.23,24 Recent findings to be mentioned later have shown DNA information and knowledge can survive for millions of years.

A contemporary example of genetic analysis is the ongoing research studying the Neanderthal, our closest non human ancestor thought to have become extinct some 30,000 years ago.25 There is fossil evidence of Neanderthals living in Europe and western Asia beginning some 300,000 years ago. Anatomically modern humans are thought to have coexisted with the Neanderthal, for instance in Europe for between 50,000 to 100,000 years. The objective of the research is to understand the relationship of the Neanderthal to modern humans and ascertain if there was any mixing of the genetic strains.26

In 1997 a team led by Svante Pääbo from the University of Munich with his student Matthias Krings successfully identified 379 base pairs from a sample of Neanderthal mitochondrial DNA. While the 379 bases were very different from equivalent human DNA, the sample was too small to be conclusive in showing the Neanderthal did not interbreed with modern humans. This occurs in part because mitochondrial DNA is composed of about 16,000 base pairs and doesn’t change when it is inherited from a mother. What was needed was nuclear DNA, found in the nucleus of cells created by combining the DNA of both parents. But nuclear DNA is scarce.

Because museum curators are reluctant to turn over rare Neanderthal bones for study and because so many samples are contaminated with contemporary human DNA deposited during handling, Pääbo devised a series of stringent tests that required a very tiny sample of the material. Only two of some seventy samples tested passed. Pääbo’s team obtained a larger piece of one of the two proven samples. The sequencing was conducted on a small fragment of a leg bone from the Vindija Cave in Croatia. Fourteen levels of sediment were excavated and dated from the cave in the 1970’s. Remains from both Neanderthals and anatomically modern humans were found in four or five of those levels. Level G3 was the origin of the bone that had been sampled and it had been radiocarbon dated at 38,310 years ± 2,130 BP (before present era) using accelerator mass spectrometry. Level G3 is considered a Neanderthal only level in the cave.

At the same time Pääbo was analyzing the Vindija Cave sample, Edward Rubin, head of the Department of Energy Joint Genome Institute in Walnut Creek, California was refining metagenomic approaches to studying microbial diversity and believed his approach could be useful in studying the Neanderthal. James Noonan, one of Rubin’s postdocs, successfully demonstrated the efficacy of the approach by sequencing 26,861 base pairs of cave bear DNA. This convinced Pääbo to supply a sample of the Vindija Cave leg bone to Noonan and Rubin for further analysis.

These two teams, Pääbo’s and Rubin’s, initiated parallel independent study efforts using different analytical methodologies. Noonan, on Rubin’s team, created a library of Neanderthal DNA by incorporating the DNA fragments into live bacteria. As the bacteria replicated, it made copies of the specific fragments. Pääbo’s team on the other hand followed a process successfully used by Schuster and Hendrik Poinar of McMaster University in Hamilton, Canada, which coated tiny beads with Neanderthal DNA fragments. In this approach one fragment per bead was amplified by PCR (polymerase chain reaction) which is similar to how DNA replicates in nature. Both teams then used a new, massively parallel technique called pyrosequencing, using pulses of light to read the sequence of thousands of bases at once. Sophisticated computer programs were then used to compare the DNA sequenced fragments to available DNA databases and identify the potential Neanderthal DNA based on its similarity or dissimilarity to a modern human sequence.

Ultimately, after conducting preliminary tests on 21 bones, three were selected for additional analysis. Further tests showed the bones were from three distinct female individuals with two being maternally related. After a number of years of research, the contributing teams presented a draft Neanderthal genome of more than 4 billion nucleotides derived from the three individuals.27 Their comparison of the Neanderthal genome with that of modern humans from various parts of the world indicates there was some small amount of inter-breeding with slightly greater genetic proximity of Neanderthals to Europeans and Asians than to Africans. A small amount of the Neanderthal genome, between 1% and 4%, could be found in the modern European and Asian genomes.

Important aspects of this research have significance for our investigations. The first is that we have a tangible demonstration that information contained in the DNA of a living organism survives its death, in the case of our example, for some 38,000 years. The second is that fossilized fragments of DNA when inserted in the cells of another living organism, a live bacterium, can be duplicated as the bacterial cells divide and multiply.

New knowledge is often gained only when a question is asked initiating research into an area not explored before. Prior to questioning if it was possible to extract and identify DNA from fossilized remains tens of thousands of years old, it was assumed that only the most superficial outline of an extinct organism would survive the ravages of time. Until the question was posed and explored, most scientists thought it would be difficult to find any, let alone enough, fossil DNA with which to work. Most would have doubted that we could insert fossil DNA fragments into a bacterium and duplicate them. Few could have imagined it would be possible to identify and sequence over 3.2 billion base pairs from a very small sample of a fossilized remnant.

Advances in mass spectrometry, optical and electron microscopy will continue to provide a means of studying information contained in fossil remnants of once living organisms. Technology is expanding the time horizon we can reasonably study and the level of detailed information that can be retrieved. For example, protein sequences have been identified and produced from bones of a 160,000 to 600,000 year old extinct mastodon and from a 68 million year old Tyrannosaurus Rex.28,29

We have seen that new knowledge is often gained when a new question is asked. Most of the techniques just described were derived from the cut and paste technology developed for genetic engineering using DNA from living organisms. Genetic engineers modify the DNA of living organisms. Most often they take genetic material from one cell in a living organism and move it into another living cell where it will work or perform the function it performed in its original host.

The new question to be asked about DNA from fossil remains is can these ancient fragments be made to function as they once did when reincorporated into a living system? We know we can extract the stored genetic information from these fragments. We also know that proteins from extinct animals can be produced in cell cultures. The question remains, can we make ancient fragments perform or “live” again by putting them back into a living system?

Andrew Pask and Richard Behringer of the Department of Molecular Genetics at the University of Texas and Marilyn Renfree of the Department of Zoology, University of Melbourne have provided an affirmative answer.30 They extracted DNA from specimens of a carnivorous Australian marsupial, the Tasmanian tiger or thylacine, extinct since 1936 when the last animal in captivity died.  The DNA was removed from four 100 year old specimens, three tiny baby marsupials who had not yet graduated from their mother’s pouch that were preserved in alcohol and one dried adult pelt, all obtained from the Museum Victoria in Australia.

Using a technique previously described by Svante Pääbo to isolate genomic DNA, they extracted tiger DNA or specifically, a gene that controlled production of collagen, a naturally occurring protein found generally in fibrous connective tissues such as tendon, ligament, and skin. They inserted this gene into cartilage-producing cells in a mouse embryo. The tiger DNA worked, switching on a marker gene in the mouse embryo. The marker gene was designed to signal the switched on collagen gene was working by turning the cartilage in the mouse embryo bluish green. A photograph of the resulting mouse embryo appears on the cover of this book. The significance of this experiment is the demonstration that 100 year old genetic material from extinct animals can perform again when reintegrated into a living system.

These scientific advances demonstrate that life information, knowledge, and function can survive the death of an organism. With this evidence of the ability to retrieve information from once animate matter and make it work again when a part of a living system, we can consider the possibility the life process irrevocably alters inanimate matter by indelibly encoding its information, the knowledge and memory of its life experience, on the matter within a living organism. Given further advances in the science and technology of perceiving and retrieving this information, we will, amongst other insights, become progressively more successful in identifying how life developed and evolved.

We now know that living matter has memory and that the information or knowledge of an organism can survive for tens of thousands or in fact millions of years past the death of the organism. We know this knowledge can be extensive, broad enough to encompass billions of base pairs of genes that under the right circumstances with the right methodologies can be recalled. We know this genetic information can be duplicated when reintroduced to a living system as basic as a bacterium. We know that once living genetic material can function again when reintegrated into a living system.

We know also that information is stored across multiple parts of the body within living organisms. We understand and have identified many of the processes and constituent elements within the human body that are involved in the creation and storage of life information from cells, molecules, neurons, synapses to neural systems. We have no reason to assume that knowledge and memory of the organism is limited to just one level of material manifestation. It is not limited to the organism or a person as a whole or to the cells of which it is composed. For this reason, we can assert that life information, knowledge and memory extend to the molecular, atomic, and potentially even particle level.

The major elements making up 99% of the human body are Oxygen (65%), Carbon (18%), Hydrogen (10%), Nitrogen (3%), Calcium (1.5%), Phosphorus (1%), Potassium (0.35%) and Sulfur (0.25%). Each of these elements in their naturally occurring state is stable or represented by molecules and atoms with enough binding energy to hold their nucleus together permanently. This gives them existence that lasts for billions of years. In addition, there are a number of stable particles (protons, electrons, neutrinos and photons which do not decay or change their form) whose lifetimes extend to an estimated 1031 years, as in the case of the proton. This gives the information, the knowledge and memory of life and its function, the potential to be significantly enduring.

CHAPTER 6

Human Uniqueness

Humanity has a history of ambivalence about human uniqueness. Many have speculated about the existence of other life in the universe and, with some optimism, of more advanced life. That ours is the only and/or most advanced life in the universe is frightening for some. Those fearful of our uniqueness find comfort in the thought that someday, beings more advanced than Homo sapiens will make their presence known and presumably help us with the challenges we face. Others choose to believe that should we destroy life on this planet, it will continue or begin again elsewhere. These thoughts tend to relieve us of the ultimate burden of responsibility for the success or failure of life on Earth. A majority of people would probably prefer to believe in a universe teeming with life rather than one where we are alone. A universe teeming with life, however, challenges thoughts of our uniqueness.

At the same time the past is full of assertions that human beings are fundamentally different from and superior to other life forms on our planet. Some theologians and philosophers believe that a supreme being ordained human preeminence. It is as if distancing human kind from the rest of the animal kingdom solidifies our origin as a result of divine intervention. In this view it is essential to eliminate the possibility of human beings as merely an evolutionary extension of prior life.

This is possibly best summed up with the writings of the 17th century philosopher René Descartes.

“We may likewise know the difference between men and brutesthere are no men so dull and stupid, not even idiots, as to be incapable of joining together different words, and thereby constructing a declaration by which to make their thought understood; and that on the other hand, there is no other animal, however perfect or happily circumstanced, which can do the likeAnd this proves not only that the brutes have less reason than man, but that they have none at all: for we see that very little is required to enable a person to speak; and since a certain inequality of capacity is observable among animals of the same species, as well as among men, and since some are more capable of being instructed than others, it is incredible that the most perfect ape or parrot of its species, should not in this be equal to the most stupid infant of its kind or at least to one that was crack-brained, unless the soul of brutes were of a nature wholly different from oursfor after the error of those who deny the existence of God, an error which I think I have already sufficiently refuted, there is none that is more powerful in leading feeble minds astray from the straight path of virtue than the supposition that the soul of the brutes is of the same nature with our own.”31

At a more secular and scientific level, there has been debate about specific attributes that distinguish human beings from other forms of life. Scientists have credited many characteristics for human uniqueness as they have tried to explain why we became the dominant life form. These debates have at various times focused on physical characteristics, like an opposable thumb, behavioral uniqueness such as tool use or on intellectual capabilities such as awareness of self and empathy for others.

Our knowledge of the numerous life forms has advanced since the seventeenth century of Rene Descartes. Most attributes cited as our source of uniqueness have been studied in various ways. For instance, the opposable thumb was one of the first characteristics cited as setting us apart from other species.

While there is clear advantage to the enhanced grasping ability and manual dexterity an opposable thumb bestows, we are not unique in having one. We know its first appearance in our family tree is more closely identified with Homo habilis, a direct ancestor of Homo sapiens. In addition, the Bornean Orangutan has both an opposable thumb and an opposable big toe giving them grasping ability on all limbs. Marsupials such as the Opossum and Koala have opposable thumbs and/or toes. Pandas, members of the bear family, have an elongated wrist bone that can be used like a thumb.32 As a consequence, we are not completely unique digitally.

Following closely behind an opposable thumb, the creation and use of tools has been cited as indicative of superior problem solving capability. Modern observation of numerous other species has shown tool use is widespread within the animal kingdom.33 Birds of many varieties use tools. This includes the Egyptian Vulture’s use of stones to crack ostrich eggs, the Australian white-winged Chough’s use of pieces of mussel shell to open other mussels and the Galapagos Islands Woodpecker Finch which spears wood-boring insects in their holes with cactus spines.34 A good example of tool making is the Striated Heron of Japan which collects berries, twigs, discarded crackers, and live insects as bait for its fishing. Herons cut and shape their bait to make it the right size for luring small fish.

Not to be outdone, aquatic animals use tools as well. Sea otters are known to carry a stone from the sea floor, place it on their stomachs, and strike it with shellfish to break open their shells.35 Bottlenose dolphins have been observed putting their beaks through sponges to protect their beaks from abrasion and irritation as they search for fish in coral reefs.36

Primates have been the object of intense study in the area of tool use. Simple examples include chimpanzee use of stones as hammers to crack nuts37 and gorilla use of sticks to measure water depth in ponds and as walking sticks.38 Complex tool use and manufacture by chimpanzees feeding on termites in the Republic of Congo has been extensively documented by Crickette Sanz of the Department of Primatology at the Max Planck Institute for Evolutionary Anthropology, Dave Morgan of the Department of Biological Anthropology at Cambridge University and Steve Gulick of Wildland Security.39

The largest termites in Africa, the genus Macrotermes, are the most commonly sought by chimpanzees. Macrotermes muelleri are found in mound nests protruding above the soil surface and Macrotermes nobilis are found in underground nests. Chimpanzees have been found to use separate methods for feeding off each type of termite nest. They fashion and bring different tools depending on the type of nest they are going to visit.

For above ground mounds, Chimpanzees brought a “fishing probe” and used a nearby twig to poke holes in the mound to access the underlying nest. Chimpanzees were seen preparing the fishing probes. They would select a stalk, break it to the right size, pull off the broad leaf on one end and turn the other end into a brush by pulling it through their clenched teeth several times to fray the end into a “brush” tip. The surface mound is covered by tiny entry and exit holes that have been refilled by termite workers after use. The Chimpanzees would use a small twig to puncture one of these holes accessing the underlying nest. They would insert the fishing probe into the hole. When soldier termites attacked the probe the Chimpanzee would withdraw the probe and eat termites attached to the probe.

For below ground nests, Chimpanzees brought a fishing probe and a stout stick. The stout stick was used to puncture the ground creating an access tunnel to the underground termite chambers. Once the pathway was created they inserted the fishing probe and fished for termites.

In a termite foraging group of 54 individuals, 29 were observed showing these specific behaviors. Of interest is that the behavior was recorded by remote cameras which showed chimpanzees arriving at termite nests carrying puncturing and/or fishing tools on 45 separate occasions. During 714 camera days of surveillance, 69 chimpanzee group visits to eight nest locations were recorded.

Beyond these earlier cited findings, researchers have observed other chimpanzee behavior encompassing tool making or more specifically weapon making. In the first recorded use of a lethal weapon by an animal other than Homo sapiens, chimpanzees in Senegal have been observed fashioning and using a sharpened stick to thrust into holes or depressions in trees to kill a small nocturnal primate called a bush baby.40 In twenty-two recorded instances multiple chimpanzees were observed hunting in this manner. One successful kill was observed where the dead “bushbaby” was subsequently eaten. The significance of these observations is the evident problem solving behavior and construction of tools or weapons with specific characteristics to match the required use. Of significance beyond use of the tools/weapons was the transmission of the knowledge of the tools to a large number of chimpanzees in the various groups.41

While opposable thumbs are subject to physical inspection, tool and weapon construction and use are identified through observation. Intellectual attributes are more difficult to study and verify. Self awareness and empathy for others are clearly intellectual insights and as such are typically not directly observable. These attributes can only be inferred from observed behavior. In these cases what is observable is behavior which implies achievement of an intellectual state.

Self awareness has been characterized in The Cognitive Animal by Gallup, Anderson, and Shillito as “The ability to become the object of your own attention. When you see yourself in a mirror, you are literally the object of your own attention, but most organisms respond to themselves in mirrors as if confronted by another organism. The ability to correctly infer the identity of the image in the mirror requires a pre-existing sense of self on the part of the organism making the inference. Without a sense of self, how would you know who you were seeing when confronted with your reflection in a mirror?”42

This view has led to two of the more widely used methods of detecting self awareness which are the mirror and mark tests developed by Gordon G. Gallup Jr. beginning in 1969. The original mirror test was performed with individually caged chimpanzees which were exposed to a full length mirror outside their cages for ten days. While initially responding to the image in the mirror with a variety of social displays as if seeing another chimpanzee, after a few days the animals transitioned from social to self-oriented actions. Their behavior changed in ways that indicated the animal knew it was looking at its own reflection. This led researchers to form the impression the chimpanzees had learned to recognize themselves.

Following the mirror tests Gallup developed the mark test. In this test an animal is anesthetized and marked on its head, face or shoulders in some way that is visible in a mirror but not visible without a reflection. The mark is put on the subject while it is unconscious so that it is not consciously aware that it has been marked. Then when it is confronted by its marked image in a mirror the researchers watch to see if it is drawn to the marks on its own body in some way demonstrating that it knows it is looking at its own image.

In the original research after anesthesia and marking with non toxic and nonodorous red dye on the brow above an eye and the top half of the opposite ear, the chimps were observed for some days without a mirror. During this time they rarely touched the marked parts of their bodies. When the mirror was reintroduced outside their cages however, their reaction was immediate, the chimpanzees watched themselves in the mirror as they guided their fingers to the marks on their faces and ears. In addition to touching the marks repeatedly, some chimps reportedly smelled their fingers.

As an extension of the initial study of the chimpanzees, the same test was administered to three different species of monkeys: stumptailed, rhesus and cynomolgus macaques. The behavior of the three groups of monkeys never changed from social displays as if they were in the presence of another monkey. Even after exposure for over three weeks to the mirrors, none of the monkeys exhibited self directed behavior. This led researchers to conclude that the capacity for self awareness might be limited to the great apes that are most closely related to human beings.

This conclusion has been supported over the years through a number of additional studies that have included dozens of species. Tests have included numerous other primates including lemurs, bushbabies, squirrel monkeys, marmosets, tamarins, capuchin monkeys, baboons, macaques and gibbons. So far self awareness has been demonstrated in chimpanzees, orangutans and bonobos. Interestingly it has not been seen in gorillas.

In the intervening decades since the beginning of the mirror and the mark tests, test subjects have included human infants and toddlers. Self awareness behavior is seldom seen before about 18 months of age. Up until this time children show social responses to the images in the mirror which include vocalizations, smiling, coyness and avoidance. Beyond human subjects recent tests have focused on bottlenose dolphins and Asian elephants, both of which have successfully demonstrated self awareness. Dolphins were studied at the New York Aquarium in Brooklyn 43and Sea Life Park Hawaii.44 Three Asian elephants were studied at the Bronx Zoo in New York City.45

Study of avian brains has been relatively limited until a recent finding of self recognition and awareness exhibited by magpies.46 In research conducted by Helmut Prior of Goethe University of Frankfurt, magpies, along with crows and ravens, joined apes, bottlenose dolphins, elephants and humans as the only animals known to see a mirror image and understand they are looking at themselves.47 In these experiments this family of birds, the Corvids, marked with red dots on their necks when placed in front of a mirror tried to touch the dot with their beak or with their foot.

Recent speculation suggests that self awareness is related to the evolutionary development of empathy. Empathy is when an animal demonstrates it is aware of and sensitive to the feelings, thoughts or experiences of another. It is when it can vicariously experience similar feelings without any explicit communication from one animal to another.

Gordon Gallup was first to hypothesize a connection between self awareness and empathy. Research for example shows great apes express “consolation” behavior with each other while monkeys do not. This capability appears consistent with mirror self recognition only in apes but not monkeys. The addition of dolphins and elephants to the small list of animals testing positive for mirror self recognition is striking because both animals are believed to be highly empathic and known for “targeted helping” which is helping that appears to take the specific needs of others into account. There have been numerous reports of both elephants and dolphins physically supporting or trying to lift up other elephants or dolphins which have been injured or incapacitated.

The theory that the two capabilities, self recognition/awareness and ability to empathize, are related is based on reasoning that the ability to recognize or infer the mental states of others is an extension of one’s awareness of one’s own mental state. Under this theory, the ability to empathize comes from an ability to use personal experience of feelings to model the existence of comparable feelings in others. Gallup, Anderson, and Shillito in The Cognitive Animal state that “Knowledge of self is an inductive springboard for an inferential knowledge of others.”

Additional anatomical research points to self awareness and empathy as emanating from the right cerebral hemisphere of the brain, more specifically the right prefrontal cortex. Gallup, et al. cites this area of the brain as appearing “to be involved in self-recognition, self-evaluation, episodic (autobiographical) memory, introspection, humor, and mental state attribution.”

Finally, more recent study of the brain of gorillas shows they have a smaller, less developed frontal cortex (Semendeferi 1999) which is consistent with their lack of capacity for self recognition. Gallup, Anderson, and Shillito further state that “Gorilla brains are not only smaller in areas that have been implicated in social intelligence, but they are also less structurally/anatomically lateralized than those of the chimpanzees and orangutan counterparts.” (LeMay and Geschwind 1975).

While the research leads us to conclude our characteristics put us into a very small group of animals, we are not alone in possessing them. There is no doubt about Homo sapiens’ dominance of all other life on our planet. There should also be no doubt about our kinship with all of the other life. Charles Darwin provided a succinct summary when he said, “There is no fundamental difference between man and the higher mammals in their mental faculties … The difference in mind between man and the higher animals, great as it is, certainly is one of degree and not of kind.”48

Evolutionary development of self recognition and the consequent ability to feel empathy are fundamental capabilities allowing the formation of societies. Recognition of one’s own feelings coupled with the understanding of how others will and do feel allows people to moderate and overcome more instinctual and animalistic impulses. To the extent a population’s feelings and reactions to a situation are shared these capabilities form the underpinnings of social mores and the development of moral codes that support the inner workings of larger societies. In this context, self awareness and empathy provide a significant basis for the creation of the Golden Rule, “Do unto others as you would have them do unto you”.

It is the confluence of many attributes in humans that enable us to differentiate ourselves from other animals. While other attributes could be argued as powerful contributors to our further progress, language, spoken and written, allows the sharing of information between members of our species. The written or recorded word gives us the unique ability to vicariously learn another individual’s knowledge without need of personal experience, contact with another or observation of another’s action. Today, this is clearly accelerating Homo sapiens’ differentiation.

Georges Anderla, a French economist and statistician, converted knowledge into binary units in order to provide a means of quantifying knowledge to measure its growth and acceleration.49 Using this approach to estimate the growth of knowledge since the birth of Christ, Anderla showed the rate of doubling of human knowledge is accelerating with the passage of time. Using all knowledge in existence at the birth of Christ as his basic unit of knowledge, he estimated the first doubling of human knowledge took 1500 years, the second doubling 250 years, the third 150 years, the fourth 50 years, the fifth 10 years, the sixth 7 years and the seventh 6 years. Anderla’s calculations were performed in 1973. All evidence suggests a continued rate of acceleration. This can be measured by a variety of factors including the number of books written, expansion of internet data bases, patents granted, etc. We are clearly in the information age and our ability to generate it, store it and use it is arguably now the most significant differentiating factor for human kind.

Another aspect of self awareness is how it enables the fully conscious decision making of human beings. We have touched on free will and the debate which preceded acceptance of the uncertainty principle, and yet the uncertainty principle is not as directly and obviously tied to the exercise of free will as is the evolutionary development of mental faculties creating self awareness. Pavlov, Maslow and others have devised intellectual constructs to explain various behaviors. Observing life forms we see a continuum of actions that range from complete randomness at one extreme to conscious decision making at the other extreme.

In the most basic forms of life, single celled organisms, we see continuous movement. Absent obvious external stimulation or proximity to a nutrient source, there is no apparent pattern to actions which appear random. If we introduce an external stimulus, an electrical shock, we see physical reaction to the stimulus with movement away from its source. We can characterize this action as a reflex as the organism seeks to avoid an unpleasant or threatening stimulus. We easily see how random motion becomes reflex in reaction to stimuli. Greater predictability of behavior comes when reflexes become instinctive. Of interest is how and when instinctive behavior gives way to conscious decision making.

With higher life forms behavior becomes more complex. Pavlov experimented with stimulus and response behaviors in dogs. Specifically he defined an innate reflex as something the animal does instinctively in response to a stimulus as opposed to a conditioned reflex which was learned behavior in response to negative or positive stimuli.50

He demonstrated that an innate reflex, salivation in the presence of food, could be associated with another stimulus, the ringing of a bell, after the animal learned that the bell was followed by food. He showed that after the learned association, the ringing bell was sufficient to produce salivation. He documented simple innate reflex behaviors, such as the pecking reflex in newborn chicks, and more complex “chain reflex” sequences such as avian nest building during mating seasons.

He concluded there was no difference between reflexes and instincts stating, “It follows from all this that instincts and reflexes are like the inevitable responses of the organism to internal and external stimuli, and therefore we have no need to call them by two different terms. Reflex has the better claim of the two, in that it has been used from the very beginning with a strictly scientific connotation.”51

Pavlov described a full range of simple to complex reflexes at one point talking about an “investigatory reflex” he called the “What-is-it?” reflex. He observed, “The biological significance of this reflex is enormous. If the animal were not provided with this reaction, its life, one may say, would always hang by a thread. In man this reflex is highly developed, manifesting itself in the form of an inquisitiveness which gives birth to scientific thought, ensuring for us a most reliable and unrestricted orientation in the surrounding world.”52

He also described “the reflex of self-defense” citing “The strong carnivorous animal preys on weaker animals, and these if they waited to defend themselves until the teeth of the foe were in their flesh would speedily be exterminated. The case takes on a different aspect when the defense reflex is called into play by the sights and sounds of the enemy’s approach. Then the prey has a chance to save itself by hiding or by flight.”53 In this way, Pavlov has characterized apparently very complex behaviors as reflexive and not involving conscious decision making.

Accepting these definitions, how do we discern the difference between nonconscious reflexes and instinctual responses and conscious thought that can lead to decision making? Christof Koch, the Lois and Victor Troendle Professor of Cognitive and Behavioral Biology at the California Institute of Technology, has explored consciousness in his book A Quest for Consciousness: a Neurobiological Approach.54 He describes complex reflex behaviors as “zombie agents” or routine behaviors that human beings perform constantly without even thinking. He suggests that conscious decision making is shown when there is a delay between the stimulus and the execution of action. He believes delay demonstrates the involvement of conscious thought as a precursor to an action of a biological organism.  Further, Koch describes the consciousness necessary to deal with situations requiring choices and the self awareness embodied in the notion of the homunculus, the “me” that exists within each of us.

Christof Koch writes, “As I just mentioned, this is one of the pivotal roles of consciousness in the life of an organism. . . .to plan for multi-contingency situations that can’t be dealt with by the non-conscious sensory-motor agents. It is probably the projections to and from the frontal lobes, responsible for planning, thought, and reasoning and the seat of the self, that create the powerful feeling that there is a homunculus inside my head, the true ‘me.’ The little person—the original meaning of the term homunculus—is part of the front of the cortex observing the back. Or, in anatomical terms, the anterior singulate, prefrontal, and premotor cortices are receiving a strong, driving synaptic input from the back of the cortex.”55

Again, we have a researcher pointing to the evolution of the prefrontal cortex as the seat of self awareness and relating it to the thought required to choose between multiple options or conscious decision making.  It is reasonable to conclude this critical integration of a highly developed consciousness of self with the ability to conduct conscious decision making is one of the most significant differentiators setting human beings apart from most, if not all, of the animal kingdom. The abilities to identify a problem, absorb large amounts of information, relate a problem and its consequences to oneself, conceive of options to choose from, decide on a course of action and implement the actions in aggregate, are representative of the highest stage of human development.

In summary, most of the characteristics cited as making humans unique are exhibited by other animals, albeit to a lesser extent than in Homo sapiens. This includes opposable thumbs, tools and weapons making and use, self awareness and empathy for others. We have observed that scientists credit the continued development of the right prefrontal cortex in the right cerebral hemisphere of the brain with setting a small number of animals apart from all others. This is believed to be the source of our self recognition and empathic capabilities. Further it is believed to play a significant role in the consciousness of the human species, the place where self is defined and where conscious decision making is initiated.

Other powerful contributors to human differentiation include language, spoken and written, and the ability to vicariously learn another individual’s knowledge without need of personal experience or actual observation. We discussed George Anderla and his computations documenting the explosion of information to which humans have access. We observed that today’s differentiators from most of the animal kingdom are our abilities to identify problems, absorb large amounts of information, relate problems and their consequences to one’s self, conceive of a number of options from which to choose, make conscious decisions on courses of action, and implement the actions.
