Self-Organization and Emergence


The reason why higher-level subjects can be studied at all is that under special circumstances the stupendously complex behaviour of vast numbers of particles resolves itself into a measure of simplicity and comprehensibility. This is called emergence: high-level simplicity ‘emerges’ from low-level complexity. High-level phenomena about which there are comprehensible facts that are not simply deducible from lower-level theories are called emergent phenomena. –David Deutsch1


How has That Which Is manifested itself? What are the most fundamental principles which it seems to have given rise to, at least in this Universe? More broadly, what are the most basic rules that seem, in our perspective, to govern the physical reality  in which we find ourselves?

Everywhere there is decay and disintegration. Everywhere, things seem to be heading toward entropy, toward complete equilibrium. Everywhere, structure seems to break down into chaos. And yet, the Universe is filled with structures, many of them extremely huge and extremely ancient, containing innumerable other structures within them, oftentimes structures of great complexity. How did this occur? Moreover, some of these structures have gained the ability to replicate themselves and make more structures, even, eventually, to evolve unanticipated structures. How is this possible? What hidden realities are at work that make chaos resolve into order—the exact opposite of what we might expect? There seem to be two phenomena which, in the Universe we know and inhabit, govern the operation of all things: self-organization and emergence. It is these phenomena which seem to have given rise to every structured thing and organized process we know of and observe, and it is these two phenomena which appear to have created the increasingly ordered levels of physical reality that eventually gave rise to our tiny and isolated species. In the opinion of an increasing number of specialists, they are the great builders of the Universe. So how might they be understood?

We need to first understand that the classical method of examining nature by breaking its components into smaller and smaller parts, a process known as reductionism, has been very successful at systematically describing enormous numbers of naturally-occurring phenomena. But reductionism became a sort of intellectual dead-end; it could describe the smallest parts of the natural world, but it could not adequately explain the way these basic entities had come together to form the elaborate structures we observe around us. Thus, the sciences of complexity, self-organization, and emergence began to grow in response to the need for such an explanation.

There is an extensive literature on these matters—the number of papers, books, and articles in these fields has increased tremendously in recent years—and there is by no means a complete consensus among scientists with regard to the exact definitions of the terms involved and the internal operations and characteristics of the phenomena being described. To a layperson like me, the various disputes among these scholars can be daunting in their complexity, to say the least. But there are research findings I think I can present with some degree of confidence.

Self-Organization

By self-organization, we mean the appearance of distinct patterns, processes, structures, or interactions without the specific direction or intentionality of any outside source. As Francis Heylighen  of the University of Brussels put it in a 1989 paper:

Self-organization may be defined as a spontaneous (i.e. not steered or directed by an external system) process of organization, i.e. of the development of an organized structure. The spontaneous creation of an “organized whole” out of a “disordered” collection of interacting parts, as witnessed in self-organizing systems in physics, chemistry, biology,[and]  sociology, is a basic part of  dynamical emergence.2

Heinz Pagels, who in the 1980s wrote presciently about the ability of the computer to simulate and model complex realities, put it this way, in remarking on the work of another researcher, Charles Bennett:

A self-organizing system lowers its entropy (a measure of its degree of disorganization) by expelling entropy into its environment and hence avoiding deterioration. An example of a self-organizing system is the growth of a plant or crystal. The point to be made about self-organizing systems is that first they are indeed complex—highly organized—and  second they got that way by starting from a much simpler system.3

The concept of self-organization is counter-intuitive, in some ways. It goes against much of our ordinary experience, where things seem to fall apart and become disorganized. But, repeatedly, we observe examples of how order arises with no outside influence. When energy in some form passes through a set of particles/units/individual entities, there seem to be definite patterns that emerge spontaneously. Examples would include varieties of cloud formation, the emergence of bubble-like structures in liquids that are heated, and a whole host of other effects that have been noted by all the natural sciences. It is this tendency of things to create spontaneous structure that allows for new structures to arise, structures which in turn make possible the construction of bigger and yet more organized structures, and so on. And although it would appear, according to several researchers, that there can be self-organization in isolation, in other words, without any ensuing emergence, (and emergence that is not brought on by self-organization) it would further appear that self-organization and emergence in combination largely produced the physical reality and its various levels of organization we see all around ourselves (in the human frame of reference).

In 2008, three physicists expressed the concept of self-organization in this way:

…if we think of empty spacetime as some immaterial substance, con­sisting of a very large number of minute, struc­tureless pieces, and if we then let these micro­scopic building blocks interact with one anoth­er according to simple rules dictated by gravity and quantum theory, they will spontaneously arrange themselves into a whole that in many ways looks like the observed universe. It is sim­ilar to the way that molecules assemble them­selves into crystalline or amorphous solids…

Similar mechanisms of self-assembly and self-organization occur across physics, biology and other fields of science. A beautiful example is the behavior of large flocks of birds, such as European starlings. Individual birds interact only with a small number of nearby birds; no leader tells them what to do. Yet the flock still forms and moves as a whole. The flock possess­es collective, or emergent, properties that are not obvious in each bird’s behavior.4

The constant interaction of particles in a given space or region creates a dynamical system, because those particles can be in different states in relation to each other over time. Self-organization involves the presence in a changing, dynamic system of attractors, areas of the system that seem to “capture” the trajectories of particles or keep other elements of the set close to them. Attractors exist in what are known as basins of attraction, regions of a system where attractors can exert their influence. The simplest attractors seem to be point attractors (or sometimes, fixed point attractors) which allow for only one final position for any particles they attract (such as a ball thrown into a jug or bowl which is inexorably drawn to the vessel’s lowest point). Another example of how a fixed point attractor operates, one given in many places in the literature, is the movement of a pendulum. The pendulum comes to rest eventually because gravity and friction create a basin of attraction that draws it into a resting state. Periodic attractors (or limit cycle attractors) cause particles (however the term particle is defined) to pass through different states on a regular basis. An object orbiting another object in a mathematically ideal way would be exhibiting the influence of periodic attractors. Particles drawn to periodic attractors are being affected by some kind of regularly occurring energy or reaction. They are not held in a fixed position, but they cannot operate in a purely random one. Strange attractors are points in a system deeply affected by the initial state of a system. Any perturbation of the system causes them to act in unpredictable ways. The greater the disturbance, the more unpredictable the actions of these attractors become, because any stimulus they receive is enormously amplified. Novel, unpredictable states can arise quickly from such attractors. It was not until the development of the computer that strange attractors, these odd, continuously moving points that never return to the exact same place in a system, could be studied. Fractal images generated by computers are examples of strange attractors in action.5

Attractors are physical states in a system, therefore, that particles tend to move toward, such as fixed points, states where the particles can settle into some sort of equilibrium, or those which can bring forth unpredictable new relationships and structures. 

So how is self-organization possible in an extremely complex system?

Physician and biologist Stuart Kauffman, a member of the Santa Fe Institute, has done as much work as anyone in the world on the natural processes that underlie complexity and self-organization. In his 1995 book At Home in the Universe, Kauffman calls the spontaneous emergence of self-organized complexity “order for free”. He explains that depending on the initial state of a system it will cycle in certain ways through its possible states, or state spaces. If there are vast numbers of possible states a system can be in, it will be necessary for attractors to draw in particle trajectories, in effect forming subsystems within the larger system, and allowing these subsystems to follow orderly patterns and establish a measure of stability, or homeostasis. Not all systems eventually do this, and the ones that don’t end up descending into chaos.6

The heart of Kauffman’s argument lies in his examination of Boolean networks, networks with components which can display only two possible behaviors. To explain these networks, Kauffman uses the example of arrays of light bulbs. He explains that a network of such bulbs can be ordered, chaotic, or in a transitional state between order and chaos. The network of lights, when operating, goes through what Kauffman describes as a state cycle, a pattern of lights that might range from only one pattern (such as alternating on-lights and off-lights) all the way to a state cycle exhibiting every conceivable state that is possible within the network. With a small number of lights, going through every possible state is easy. With increasing numbers of lights, however, it becomes progressively more complicated.

The number of different states the network can be in is governed by the number of lights in it. A single lone light bulb can exhibit only 2 states, either on or off. Two lights can exhibit four possible states (22) namely,  both on, both off, the first one on and the second one off, or the second one on and the first one off. Three lights can exhibit eight possible states (23), and so on.  If we keep adding one light to the network, it doesn’t take long for the number of possible states to grow very large. For example, a mere 20 lights can exhibit 1,048,576 different combinations (220). One hundred lights can exhibit 1,267,650,600,228,229,401,496,703,205,376 states! (That’s over 1.2 novillion.) Some idea of the magnitude of this number can be gained this way: if each of the possible 1.2 novillion+ light combinations manifested itself for only one one-millionth of a second, it would take more than 2.9 million times the estimated age of the Universe for each of them to be manifested.

There would have to be, in any such system of lights, a way of controlling whether each individual light was on or off. There would be a system of “inputs” for each bulb, connections to other bulbs  and/or to itself. In a network where each light had 4 or 5 random inputs, the network would be unpredictable and chaotic, going through its state cycles in extremely long sequences, even accounting for the presence of attractors that might give it some organization, and highly vulnerable to any outside disturbances of its operation. But if each bulb were only controlled by one or two others, and each bulb could only be on or off, order would spring into existence regardless of the size of the network and how many states (patterns of  lights either lit or not lit) it could display. Kauffman discovered something utterly amazing. Even in a system of 100,000 lights, which has 2100,000 possible combinations, if each light controls only itself and one other random light (2 inputs per light), the system will fall into a mere 317 different state cycles out of all the enormous number of possible cycles it could go through. (And 317 is about the square root of 100,000.) The conclusion is compelling: Given the right initial conditions and interactions, order can arise spontaneously in even the largest arrangement of entities, without any outside intervention and without any intentionality.7

Scientists are also investigating the phenomenon of self-organized criticality, a hypothesis most associated with the late Danish physicist Per Bak. The idea behind it is typically illustrated by picturing grains of sand being dropped on to a surface. The pile of sand that results can only grow so high before it begins to exhibit a characteristic shape and a structure that produces avalanches of various sizes if additional sand is added to it. The pile is self-organized in the sense that no one has to shape it. In fact, it spontaneously forms substructures of various kinds. And it is in a state of criticality because it is unstable and the results of adding more sand to it are unpredictable. Will adding more sand cause a minor avalanche or a catastrophic one? Bak saw the sand pile’s structure and behavior as a metaphor for all kinds of processes in the physical world that are driven to self-organization and instability by the constant addition of some crucial component. In the words of M. Mitchell Waldrop,

a steady input of energy or water or electrons drives a great many systems in nature to organize themselves in the same way. They become a mass of intricately interlocking subsystems just barely on the edge of criticality—with breakdowns of all sizes ripping through and rearranging things just often enough to keep them poised on the edge.8

It would appear, therefore, that not only is it possible for structures in nature to self-organize, it is rather common for them to do so. The means by which this happens are still being elucidated and debated over, but that it does happen can no longer be doubted. It is this tendency of nature to self-organize, to create structures and substructures which are mathematically describable, and to create spontaneous networks of interlocking and interacting components that allows for the existence of emergence—the appearance of a new “level” of reality.

Emergence

How do the professionals researching emergence define its properties? The question is still being investigated intensely, but some consensus now seems to be developing.

In a study entitled Causality, Emergence, Self-Organisation, published in 2003, the editors of the study, Vladimir Arshinov and Christian Fuchs, prefaced the book with a summary of what they believe to be the principal characteristics of emergence. They are: synergism, the interaction between two or more entities in a “co-operative” manner; novelty, the emergence of previously unobserved qualities; irreducibility, meaning that the process cannot be reversed to create the same entities that produced it; unpredictability, the creation of an unanticipated result; coherence/correlation, meaning that the emergent phenomenon creates a unity that encompasses its sources; and historicity, meaning that emergent phenomena are not pre-ordained.9

Tom De Wolf and Tom Holvoet  of the Catholic University of Leuven, in Belgium, did an extensive review in 2005 of the literature concerning emergence. They concluded that  genuine emergence has the following characteristics: Micro-macro effect. The behaviors and properties of the emergent system are a result of the interaction of the entities within it. This is considered by almost all researchers to be the essential feature of an emergent system. Radical novelty. The emergent entity cannot be something that would be anticipated by examining the parts of the system in isolation. Coherence. The organization maintains itself over time. Interacting parts. Parts existing in parallel to each other are not sufficient, and cannot produce emergence. Dynamical. The emergent system materializes over time because of new attractors in the interacting system that produces it. Decentralized control.  No individual part controls the whole system. Two-way link. The interacting parts give rise to the new system. The new system in turn affects its parts. Robustness and flexibility. The overall emergent structure is less sensitive to disturbance  or destruction than any single entity within it, and can maintain itself even if it sustains some damage.10

So the essence of emergence appears to be an interaction of elements that brings about an unanticipated, unpredictable outcome, an outcome that can only exist in the presence of this interaction. (See the chapters Synergy and Feedback Loops and Chains of Unanticipated Consequences in this section of the book for more elaboration on these points.)  The emergent system in turn creates a new interactive dynamic that can set the stage for a still higher level of organization. This process does not need any conscious direction and its ultimate result—if there is an ultimate result—will be the sum of all of the unpredictable outcomes generated at every level of the emergent process.

What might stimulate this process? In Robert Hazen’s 2005 study on the origin of life, he identified what he sees to be the factors contributing to the emergence of complex patterning: Concentration of agents. By this Hazen means that there must be sufficient numbers of units (grains of sand, stars, neurons) in close proximity to each other. “Below a critical threshold, no patterns are seen.” Interconnectivity of agents. The more numerous and complex the interactions of individual entities, the greater the chance of emergent phenomena. Energy flow through the system. “The emergence of complex patterns evidently requires energy flow within rather restrictive limits: Too little flow and nothing happens; too much flow and the system is randomized—entropy triumphs.” Cycling of energy flow. Periodic fluctuations in energy and the presence of periodic cycles of  change seem to have a dramatic effect on emergence.11  So emergence seems to involve the effect of energy passing through a system of densely concentrated and closely interacting particles in a particular way, with the term “particle” defined very broadly. As we go backward in time or downward in scale, the interactions between particles (of various sizes and complexities) is less organized and more and more subject to purely stochastic processes.  

The implications of all this are enormous. Nobel laureate Robert B. Laughlin, in discussing the effect the growing study of emergence is having on the sciences, observes that there is a great deal of resistance in the scientific community to abandoning reductionist ideas and embracing emergent ones. Nonetheless, he contends that emergence is such a powerful and useful concept that it will come to dominate humanity’s study of nature, alter our perception of what mathematics is capable of, and usher in what he calls The Age of Emergence, the era when our view of reality is defined by what he calls “the higher organizational laws of the world”.12 If Professor Laughlin is right, then we will come to see the presence of emergent phenomena not just in the sciences but in every area of existence, including an explanation of the emergence of human society and culture.

Personal Conclusions

So what do I conclude from all of this? Here are my hypotheses, based on my (limited) understanding of these phenomena:

First, self-organization and emergence seem to be evolutionary and self-perpetuating in nature. Self-organization (usually) causes emergent phenomena to come into being. Various and diverse emergent phenomena can in turn self-organize to produce a new, larger, more comprehensive  emergent phenomenon. Where this process will end cannot, by its very nature, be predicted. Each level of reality is more and more unexpected; the cumulative effect of all these levels, one “on top” of the other, is the least predictable thing of all in the process. As individual phenomena emerge into the next level of organization, they become subsumed within it. These phenomena are harnessed, so to speak, and become part of an integrated system.

At every level of physical reality, particles tend to link up with other particles because they are drawn together by distinct areas of space-time. (Could we say that they are simply following the path of least resistance?) This linking up becomes more complex as the levels of physical organization become more elaborate. At the highest level of organization—human society—so many variables are at work in this linking process that the effects become more and more unexpected.

It is difficult to see how basic physical interactions can directly lead to the emergence of life. The emergence of chemical principles seems to be a necessary intermediate step. The transition from basic physical particles to human society required a great many intermediate steps.

The micro brings forth the macro; increasing amounts of energy are required to reduce the macro at various levels to the micro. As Timothy Ferris has pointed out, enormous energies are required to tear matter down to its most fundamental levels, energies that more and more approximate those which must have existed at the time of the Big Bang. It would be quite possible, for example, to destroy a complex structure by breaking it apart into small pieces. But breaking it into its constituent molecules would require much more energy, breaking it into its atoms would require an enormous amount of energy, and breaking it into its quarks and leptons would require an inconceivable amount of energy. The end results of emergence are not necessarily permanent; emergent phenomena can be undone, but doing so requires undoing a great many steps and the marshaling of energies that are not easily acquired.

When we reach down to the most fundamental level of physical reality, using reductionist methods, there seems to be nothing but chaos. Emergence theory allows us to account for the order we find at various levels higher than the chaotic, basic level of physicality. Emergence theory therefore puts the reductionistic view in a new perspective. No longer is reductionism simply a descent into chaos; it becomes a descent into origins.

Using reductionistic methods in combination with the emergent perspective allows us to trace our story backward through time, starting with the “highest” level (that is to say, the  level that is the ultimate result of all the preceding emergent levels) and ending up at the most fundamental level of physical reality, the point at which we can go back no further.  We would therefore start with the human cultural and social worlds, their intricate rules and interrelationships, and all the “structures” which are no more than approximately understood common ideas held in the neurons of human brains. We would trace the emergence of human society and culture to consciousness, which is less organized and more random than the social and cultural worlds. We trace the origin of consciousness to the evolution of a particular kind of brain, noting that the steps that led to the biological evolution of higher-order nervous systems were more random than the ordered functions of the brain produced by these steps. We see that the evolution of the brain was an emergent result of the general evolution of multicelled beings, which was a broader, less defined, less organized phenomenon than the emergence of highly advanced collections of neurons. The evolution of multicelled beings emerged from the relatively more chaotic world of one-celled organisms. These one-celled organisms were in turn brought about by the emergence of nucleic-acid based life existing without membranes, brought about by the interactions of molecules built around carbon atoms. These molecules were themselves the product of a long chain of basic, evolving, self-reproducing chemical units (perhaps preceded by simple metabolic processes) which existed in a highly chaotic state of seemingly random movement, and which began to undergo changes because of the interaction between their own replication errors and changes in the physical environments in which they existed. The atoms which came together to form these molecules were in turn assembled and held together by fundamental particles, which in turn were the product of the emergence of the four fundamental forces of nature at the first moments of the Universe’s existence.

Every level of organization is both more coherent and more information-dense at the same time. Every level of organization contains all the information of all the levels from which it emerged. In one perspective, reality can simply be seen as the generation, transference, accumulation, and aggregation of information.

Is the social organization created by human consciousness the ultimate stochastic dynamical system, because of the number of possible outcomes or actions of the “particles”? When a “particle” knows that it is a particle, and that it is possible do things that are not pre-determined, does that create a unique form of dynamical system?

Not all areas of the Universe have been resolved into order. There are still areas, for example, where the basic level of physical reality is the only one, and nothing has emerged from it. Other areas have gotten no farther than basic chemistry; others no farther than basic biology. The ways of life and social interaction created by the human species involve an extraordinary—and quite possibly, very rare—number of emergences “stacked up” on each other. And there would have been no conceivable way of predicting that the randomly interacting quarks that came into being moments after the Universe’s beginning would ultimately bring forth human society and culture.

Self-organization and emergence have produced certain fixed regularities in the operation of physical reality. In the human perspective, these regularities appear to take a particular form:


They are called the laws of nature. So now we turn to them.

That Which Is

The oldest existing reality cannot be called anything more than “that which is”. It is beyond all human comprehension or any attempt at human definition. It is the foundation or fundament out of which the physical Universe we inhabit arose. It is something deeper than merely an Aristotelian “First Cause”. It is that which would still remain even if all levels of physical reality were to be eliminated. It would remain even if there were no space-time or energy-matter. It is quite possible that what I am calling “that which is” has, from our point of view, existed forever and will exist (however the term “exist” might be understood) forever into the future. (Of course, our concepts of past, present, and future are meaningless to that which is, or might be, eternal.)  Those who are religiously inclined might view “that which is” as a god or gods of some sort. But given the often anthropomorphic conceptions of gods that humans have devised, or the logical difficulties involved in postulating a god which is both immanent (within every created thing in the most intimate sense possible) and transcendent (above and beyond all physical or temporal boundaries),  the attempt to embody “that which is” as a god or gods strikes me as simply another human-originated attempt to describe the indescribable. “That which is” will forever be beyond our limited ability to understand it.

We are part of how “that which is” manifests itself, but we do not live at its level and we are wholly incapable of seeing reality from its perspective, as if the term “perspective” had any meaning in this case.

One can argue that “that which is” must lie within the boundaries of mathematics. I suppose a case for this could be made. It is possible that what humans call, in their various languages, mathematics, are the unbreakable rules by which “that which is” must operate and manifest itself on different levels of organization and existence. But is mathematical reality itself emergent, that is, something which is a level of organization grounded in “that which is”, or is mathematical reality itself “that which is”? (See Is Mathematics the Real Reality?)


Are humans who have experiences which they believe to be mystical or transcendent touching (in some way) “that which is”? Is this the Tao that is spoken of in the Tao Te Ching? Or are these seeming moments of insight strictly the product of a unique chemical circumstance in the brain?  Definitive answers to such questions are, of course, impossible to give. About the best we can do, perhaps, is to say that there must be some ultimate reality out of which every logically possible thing emerges, and leave it at that. Beyond that point, we cannot go.

The Search: The Existential Dilemma of the Human Being

I.

In the face of reality’s complexity, especially the complexity represented by the existence of other people, there are certain essential questions which I believe that all humans confront (if they live long enough and are mentally lucid) whether they realize it or not. Taken together, the search for answers to these questions forms what I call the existential dilemma of the human being. These are the questions which must be answered if a human wants to make sense of the world and survive within it. This dilemma may not be consciously articulated, but I am convinced that it is at least felt, and is perhaps the source of the vague unease many humans feel at odd times in their lives. I am convinced that many humans embrace religious convictions because religion seems to end this search. Other humans seek resolution of these issues from sources outside of religion, chiefly philosophy. And many people come to believe that there are no definitive answers to any of these questions. (That lack of answers carries its own consequences, as we will see.)

In my opinion, the major existential questions humans want answers to are the following::

1.     What am I?
2.     Who am I?
3.     What is the world and how did it come to be?
4.     Why do humans exist?
5.     What is my place in the world?
6      How should I live my life?
7.     Can I know myself?
8.     Can I know others?
9.     Can others know me?
10.   Who can I trust, and to what degree?
11.   How can I protect myself and my loved ones from the world?
12.  Is there a larger purpose to life than mere survival, and if so, what is it?
13.   What is right and what is wrong?
14.   What is true and what is false?
15.   Why is there suffering?
16.   Why do evil and injustice exist?        
17.   Is life worth living?
18.   Is there such a thing as meaning, and if so, is it discoverable?
19.   What happens when people die?

Naturally, most people don’t consciously dwell on such matters very often, if at all. For the vast majority of us the demands of everyday life are such that there is very little mental or physical energy left for such “idle speculation”. And yet, I suspect that these are the questions, even if unspoken or not contemplated, around which humans build their lives and about which they are most concerned.  In my view, whether they know it or not, I believe most humans both want and need answers to these questions, ones that will help them reject a conclusion that for most people is utterly intolerable, namely, that existence is absurd and nothing ultimately means anything—including our own lives.

II.

Upon birth, we must suppose that an infant faces a physical reality which is totally incomprehensible to him or her. Instinctive reactions, born of evolution’s long history, govern a baby’s behavior. As the neurons of the brain interweave themselves and make connections (while pruning back others), the earliest self-awareness an infant/toddler has begins to emerge. An “I” is beginning to take shape, the sense of being an object differentiated from other objects, a feeling of being connected by the senses to the outside world. So the initial existential question we face is, in my view, What am I? Children tend to quickly learn some variation of an answer to this question: I am a baby, I am baby boy or baby girl, I am something which belongs to mommy or daddy, I am someone who has needs. Young children just learning to speak are often excited to see other very young children, and will often exclaim, “Baby!”, upon seeing them. This recognition of others is a crucial part of personality  formation and categorization. There are big people; there are little people. The earliest memories, usually from around the age of 3, indicate (in my view) a stage in the development of the self, and a new step toward defining the “What am I” question.  All throughout life, as roles are acquired and membership in various groups is understood, and assimilated into a person’s consciousness, the answers to What am I grow increasingly elaborate and complex. All sorts of categories now seem applicable: member of a family, member of a neighborhood, member of a school, member of a town, member of a nation, and so on. The answers to the question “What am I” form crucial aspects of an individual’s identity. By identity, I mean the association of the “I”, the self, with various definitions which seem to be congruent with experience. “What am I” continues to be asked (either consciously or unconsciously) all through life. Answers can include, “a child”, “a teenager”, “an adult”, “an employee”, “an old person”, and, if there is sufficient lucidity near the end of one’s life, “a dying person”. In a sense, What am I is the ultimate, primal, permanent question of life, one that follows us from birth all the way to the moment of death.

Who am I? is a variation on What am I?. The various definitions associated with the self, combined with an individual’s unique experiences and genetic predispositions, form a biographical narrative in a human brain (assuming the person in question is of adequate intelligence). This narrative is strengthened by the possession of a name, a ready identifier which becomes indelibly linked to us.  We say, in various ways, “I am [name]. I have a story that is mine alone. I have my own set of characteristics and ways of seeing the world. No one else is me. I live inside of myself, and I know my story better than anyone. Things have happened to me. I have done things. I have thought and felt things. I will be me for the rest of my life.” An individual human might change the definition of Who am I several times over a lifetime. And some people never quite get a handle on it. The answers to the question, Who am I can be vague, somewhat shapeless, indefinite, and malleable, as a human’s life unfolds and follows often unexpected paths. Answers to this fundamental existential question can change under the pressures of new circumstances, dramatic personal events (especially crises), and new, age-related perspectives.

As a person more and more coherently defines himself or herself as a kind of living being existing in a definite kind of world, questions tend to arise about the nature of that world and how humans came to be in it. The overwhelming majority of humans are taught answers to these questions by the adults in their culture, adults who have absorbed cultural traditions that are centuries or even millennia old. The dominant mythology of a given society is usually learned at a young age, and it can be remarkably difficult to dislodge from a person’s consciousness. The root of this difficulty, many times, is the fact that this mythology has been imparted by respected and beloved elders. Further, this mythology is generally learned when the brain is at or near its peak ability to learn. Mythology is also tenacious because of its strong emotional components, especially ones which exalt the group of which a child is a part. Cognitive dissonance can occur when cherished mythology is exposed to empirically-based scrutiny, and the mythology’s contradictions, illogical aspects, and  general explanatory flaws are exposed.

The questions of what the world is, how it came to be, and how humans came to be form the core of a human’s mental picture of himself in relation to the Universe, and his relationship to a hypothesized Divine Creator (or creative force) who is ultimately believed to be responsible for bringing that Universe, and by extension the human himself, into existence. The answers embraced by a human to this set of questions tell us, in many ways, a person’s opinion of herself and the others with whom she lives. Many humans prefer answers to these questions that tend to reaffirm their sense of being important in the scheme of things. It is this comforting belief in human centrality that is most brutally challenged by the facts of our utter spatial and temporal insignificance.

III.

When a human asks, What is my place in the world?, he or she is quite possibly asking one of several things, or perhaps several things in combination. The person may be asking, “What is my rank or social standing compared to others?” This is a question of great importance, especially if a human comes to believe that his or her rank or social standing is unchangeable.  A person born into a “low status” family may come to develop a fatalistic view of human life and human opportunity, seeing himself as doomed to a life of menial labor and hardship. A person born into a “high status” family may come to develop a sense of entitlement and a feeling of superiority over those who are “lesser” than she. In a sense, when we ask about our social rank we are asking, “How important and powerful am I compared to other people?” (In societies with some degree of social mobility, the desire of many to be more important and more powerful can have major consequences.)  What is my place in the world, therefore, is in one way an inquiry into the possibilities of one’s life

Another answer to What is my place in the world ? can be a human’s belief about what he or she should do for a living or contribute generally to society. In other words, it’s really the question, “What should I do?” Some people come to see themselves as possessors of greatness, those tagged by “Fate” to do memorable things and accumulate great wealth. For others, “What should I do” is a question they never really answer completely, drifting through the years with no definite course.  And for most, “What should I do” is answered by accepting the advice, norms, training, education, and sometimes compulsion offered or imposed by others. Many people are never given any choice at all, and do only that which others choose for them.

Finally, What is my place in the world? can be a more abstract question related to other existential questions about the meanings of life and existence. A person may also be asking, “Where do I fit in the history of the world? How did I come to be in this situation at this place and time?” The answers a person gives to these variations of the basic question are heavily dependent on his or her level of learning and the cultural narratives he or she has been raised with.

How should I live my life? involves not just questions of social standing, but also an individual’s value system and personal philosophy. The most fundamental answer is, “through right living”, but the definition of right living can vary greatly from person to person. Is right living the steady and monomaniacal accumulation of power over others, the constant seeking of advantage, and the immediate gratification of all desires, regardless of the consequences to others? Right living to other people means a code of behavior to be followed, a disciplined way life, one replete with rules of conduct toward others, a life of duties and obligations. To others right living implies an effort to experience all that can be experienced while respecting the rights of others to engage in the same pursuit. There are myriad ways right living can be understood, therefore. Moreover, the definitions of right living may not have clear-cut boundaries, can shift dramatically, and can be improvised throughout a person’s life in the absence of an elaborately thought-out value system. In many ways, human history has been affected by the clash of answers to the question, “How should I live?” Many are not content to decide this for themselves—they seek to impose their answers on others out of the conviction that they, and they alone, know the proper course.


IV.      

In the face of our  isolation within the physical Universe, we take comfort, perhaps, in the idea that we on this tiny planet at least have each other. But as we struggle to make ourselves understood, as we wrestle with our own natures, and as we struggle to understand others, we may find ourselves increasingly unsure of the degree to which we actually do have each other. We therefore ask the following urgent questions: Can I know myself? Can I know others? Can others know me? The answers are ones we usually don’t want to accept.

It takes many years for the typical human to understand, both emotionally and intellectually, that he or she sees the world in a way unlike that of any other human. When we are children, we simply assume, I believe, that everyone sees what we see and feels what we feel. (It could be said that when we are very young children we are so absorbed in our own reaction to the world that we simply don’t care what anyone else feels.)  The different reactions of people to the events of life are puzzling when we are young, even disturbing to us. How can you feel that way? How can you not agree with me?

But as we get older, we usually find the nature of our interactions growing more complex. More and more subtle misunderstandings arise. Other people often confuse us or anger us with their seemingly inexplicable behaviors. A conclusion usually becomes more and more inescapable to us: no one can possibly know the interior mental world of another human being, and, by inference, no other human can really know ours. Of course, from our youngest moments, most of us have been spoken to and immersed in the ocean of a particular language. We have been taught to communicate with others using this medium in the hope that we could convey our internal experience to others. But the inadequacies of language—its ambiguity, its imprecision, its frequently abstract nature, its infinite shades of meaning—impede our ability to convey meaning to each other. Gradually, if we force ourselves to look at it honestly, we come to realize that no one will ever truly understand 100% of what we mean. We come to realize that even we don’t always know what we mean, as we so often try to find words for feelings that no words can express. This realization manifests itself sometimes as resentment, sometimes as sorrow, sometimes as amused resignation, sometimes as a sort of cosmic indifference. In many of us, it creates a sense of  existential loneliness, and an unbridgeable isolation from other people. And there is more.

When we are in quiet moments, we often cannot get a handle on what we are experiencing at the eternal present. When we fall into the infinity of mirrors that is the attempt by the brain to understand the brain, it often produces a sense of indescribable mystification. We are reduced to thinking, “What is all this? What is experience itself?” Our brains’ inherent inability to grasp the whole reality that surrounds us strikes us at these moments, even if we don’t put the sense of how  strange we feel into any words. We are simply swallowed up by our own minds, which are the product of a lifetime of sensations and interactions that have had effects on us that are simply too complicated for us to grasp. Not only are our reactions to experience too complex to sort out, these reactions are based on information about ourselves that oftentimes we just don’t have any more. We often don’t have any idea of what the root of a specific emotional response actually is. We have lost the thread of our lives, and it cannot be located again. 

It is at these moments that an even darker realization occurs to us: since we can not convey total, unfiltered meaning to each other, and since we cannot account for all the many conflicting and competing emotions within us, we not only will never understand others, we will never really understand ourselves. If we dwell on this, the absurdity of the situation in which we find ourselves crashes down on us. We will never know others; others will never know us; we will never know ourselves. And yet, here we all are, thrown together, having to live with each other and interact with each other. It is as if the entire human population is a set of inmates, each one a prisoner in his or her own skull, trying to grasp enough of the world to survive in it (or, hopefully, prosper), and trying to communicate with the other prisoners trapped inside of their skulls.  It is in communication that our only hope of lessening our sense of isolation, and hence our existential loneliness, lies.

Communication is the basis of human interaction and in a very real sense, of human survival. Humans must convey part of their internal experience to others, right from the start of life, and must in turn attempt to apprehend part of the internal experience of others. But as I said above, such communication will always be approximate. (The more abstract and less concrete the concepts used in communication, the more approximate this communication will be.) I will examine the significant impediments to communication in more detail elsewhere. (See The Nature and Continuing Evolution of Language.)

Our only hope of understanding anything about each other is in the possession of common ground. If  I refer to something as being red, only your visual experience of a red object will suffice for you to grasp my meaning. (The mathematical formulae describing red as a wavelength will not suffice if you have never seen a red object.) If I tell you something is hot, only your tactile experience of a hot object will stir any degree of understanding in you. (And your associations with the words red and hot may be very, very different from mine.) At a minimum, we need some sort of linguistic and/or gestural common ground to grasp part of each other’s meaning. We need a store of common experience and common points of reference, a certain amount of shared information and shared skills (which is why education of some form is indispensable to people). But we will have to accept the fact that since it is logically impossible to be another person, and to have the whole set of that person’s knowledge, experience, emotional state, and state of consciousness at our disposal at a given moment of communication, we will never entirely tear down the walls of isolation. We will perceive reality in a way which may be very similar to others, but it can never, by definition, be exactly the perception of any other person. (The upshot of all this is if I’m right, I can’t be 100% certain why I feel the need to express this to you. And you can’t be 100% certain you know what I mean.)

Are the ambiguous nature of communication, our resulting sense of existential loneliness, and the unanswered mysteries of our own personalities the real origins of our quest for certainty? Are they the sources of our desire to believe that we understand, and the illusion that we are understood? Do the huge questions most of us feel are so important about God, death, suffering, the meaning of existence, the nature of truth, and others like them have their root in our sense of isolation? Does this feeling of being isolated engender in us the desire, ultimately, to be connected with a reality where the self can be subsumed into a greater and more significant whole and language has a single, definite meaning? Can it even give us the desire to live in a reality where words no longer matter?

V.   

Many people find out about human cruelty and perversity far too early in life, and any hope these people have of being able to count on and be reassured by the behavior of others is critically damaged, often irreparably so, by trauma suffered in childhood. Most others are more fortunate, but sooner or later, everyone is exposed to the sins and weaknesses that our complex psychologies give rise to: corruption, lies, betrayal, and injuries in endless variety. Since humans must be able to predict and anticipate the behavior of others for their own safety (and indeed this is so crucial that some researchers believe consciousness itself arose out of this need), the question, Who can I trust, and to what degree? is of the utmost importance. It’s worth looking at what we mean by the word “trust”. (See also The Sinews of Trust in Section VII for a fuller discussion.)

Trust can be thought of as the willingness to let our defenses down—to be vulnerable, either physically or emotionally, or both—with another human or group of humans. This willingness to be vulnerable is based on an assessment of the predictability of other people’s behavior. If, in a particular setting, we feel that those who are present with us mean us no harm (at minimum), are positively inclined toward us (in a middle case), or would sacrifice important things to defend us (the maximum case), there is a feeling of trust. If I know that you are not going to try to hurt me, and will in fact be my ally, I can set aside my internal readiness to fight or flee, and relax emotionally.

There are, obviously degrees of trust between people, ranging from trust in a person in a limited setting for a limited duration all the way to people one can trust with one’s life. Knowing the difference between those we can trust with small things and those we can trust with the ultimate things is of obvious evolutionary importance. It is trust of an unspoken kind that regulates much of ordinary human behavior, and in situations where trust between people is low or completely absent, anarchy and “the war of all against all” tends to be the rule.

Is betrayal so sharply felt because the need for trust is so deeply embedded in our brains? There seems to be something fundamental about betrayal that causes humans to respond to it with deep anger and hurt. Is this an indication of how ancient the need for trust really is?

We see the suffering of others; we experience suffering, perhaps very severe, ourselves. We can imagine injury and pain from experience, and if we are rational (and not under the stress of life-or-death circumstances) we seek to avoid them at all costs. We especially seek to protect our children from them, very often at the price of our own well-being. We hear of or even witness horrors; dark fears insinuate themselves into our thinking, and one of the most elemental of all questions demands our attention: How can I protect myself and my loved ones from the world? I say “the world” in this formulation because many of our fears are centered in the generalized “others” who share the world with us, the strangers who may do us harm. (The issue of trust is at play here, of course.) We seek to give ourselves and those we love safe places in which to live, and we seek further to control as many of the potentially dangerous variables in our environment as we can. The inability to control these variables can lead to a feeling of helplessness, rage, frustration, despair, and chronic fear. People trapped in war zones or in generally lawless areas know the terrible urgency of finding safety, in many ways the prime objective of a living thing. The fear, caution, preparation, and alertness demanded by the need to keep ourselves and our loved ones safe has been one of the chief factors driving human history. Magnified over an entire population, the need to keep ourselves and our loved ones safe is at the heart of our defense efforts (although the individual soldier may be fighting under compulsion).

The issue of protecting one’s self and one’s loved ones is so significant that it is usually the priority consideration in a person’s life. The quest for security and the need to prepare for dangers which may emerge either from malicious strangers or unpredictable nature can lead to the sacrifice of all other values. Conversely, the failure to protect one’s loved ones (or the perceived failure) can lead a human down the most grievous abysses of despair. The protection of one’s kin, in particular, may have extremely ancient evolutionary roots; only the survival of the precious genes guarantees continuation of our line. The anguish we feel when those we love have been harmed may in part be rooted in this. Add in the depths of emotional attachment that people usually feel for those related to them, and the suffering of our loved ones becomes utterly intolerable, a fate to be avoided at any cost, including the abandonment of even the most deeply held moral beliefs. How can I protect myself and my loved ones from the world? For most people, the answer is, “Any way I have to.”

Survival may be a tremendous achievement for many people, and the minimal protection of themselves and their loved ones a true victory, given the often harsh realities of the world. But most people, at least in the more economically advanced areas of the Earth, seek something more once the basic minimums of life have been secured. Specifically, most people want to know the purpose of the human enterprise itself. They want to know, “Is there a larger purpose to life than mere survival, and if so, what is it?” This question is related to “How should I live my life?” but it is not identical to it. It contains the unspoken question, “Why do we live?” It also encompasses more than just one’s self, for it implies that humans as a group have some sort of mission to fulfill, and that this mission is both significant and discoverable. The answers people give to this question very often reveal deeply held personal beliefs or prejudices. A person might say that the purpose of life is to prepare for the establishment of the Kingdom of God, or that the purpose of life is to prepare for Eternity, or the purpose of life is to eradicate human suffering, or the purpose of life is to grab everything for yourself that you can before you die or the purpose of life is to have children and grandchildren and pass one’s family name down. Others might say in response to this question, “Purpose? There is no such thing. We just live and do the best we can, and then we die.” That statement very often also reveals deeply held beliefs, although most people might not readily perceive this. However it is answered, one thing is consistent: if a purpose is believed to exist, it is considered the main overall reason a person lives his or her life. It is the ultimate, overriding goal. It is, in essence, the root of a personal philosophy.

           
VI. 

At a young age, most people begin to be given what will turn out to be a long series of instructions on what to do and what not to do. They will have these rules impressed into them in any number of ways, many of them physically hurtful ones. Also at a young age people will begin to glean lessons from the culture with which they are surrounded about what constitutes “right conduct”.  As a person grows older, he or she will generally begin making judgments about the behavior of others, perhaps comparing it to the standards of behavior which they have absorbed (in their uniquely individual way) from their kinship group, neighbors, and community. Whether they realize it or not, when they do this, most people are applying a set of standards that govern a general system by which the behavior of others is regulated (and by which their own behavior is in turn regulated). They are forming answers to the question, “What is right and what is wrong?

This question is, naturally, at the very heart of what humans call their moral or ethical systems, and it has been answered in any number of ways. Wrong conduct, being abnormal and disruptive, seems to be identified more readily than right conduct, which tends to become part of the human mental background, part of the definition of “normality”. Among the definitions of wrong conduct humans have given over the centuries, the following tend to be the most prominent:

·  Whatever violates the sacred teachings of the religion which is dominant in our culture.
·  Whatever disrupts the orderly conduct of business and social relationships in our society.
·  Whatever undermines the unity of our people.
·  Whatever shows disloyalty to the rulers of our society.
· Whatever violates the prerogatives of parents over their children.
·  Whatever brings dishonor to and condemnation of a family.
·  Whatever violates the person or property of a human being who has committed no    offense against anyone.
·  Whatever undermines the trust people in our society have to have in order to live with  each other.
· Whatever is, in general, contrary to the laws, norms, and traditions of our people.
· Whatever actions those in power take that are corrupt or unjust.
·  Any combination of any of the above with varying degrees of emphasis on the individual guidelines.

Notice that only two or three of these statements could in any way be interpreted as emphasizing the primacy of the individual or the rights of a human against the power of those who govern him. In fact, throughout human history, questions of right and wrong have seldom been left to individual judgment, nor have they focused primarily on the rights of the person. Wrong conduct has generally been defined as conduct which undermines the collective well-being of a society, conduct which attacks the institutions on which the society is based. (Right conduct, naturally, is generally considered the exact inverse of each of the above statements.) Virtually every human who has ever lived, until the last few hundred years, has lived under definitions of right or wrong behavior similar to this. Respect for the individual’s privacy and personal conduct has, in the larger context, been an aberration in human history, not the norm.

But humans face moral and ethical dilemmas of a smaller scale every day, ones for which guidelines are not always clear. How should I treat those whom I don’t know? How friendly or unfriendly should I be to those I do know? Should I always be bluntly honest, or should I value tact above all? Should I help people I don’t know, or ignore all but the needs of my own family? Can I rightfully take advantage of the ignorance or gullibility of other people? It is this mass of billions of small moral decisions that often steers the day-to-day course of our world more than the broader and more formalized rules that govern societies.

Questions of right and wrong, can, of course, be given more ominous interpretations. What is right and what is wrong? Some answers are:

  • Whatever benefits me is right; whatever doesn’t benefit me is wrong.
  • Whatever promotes the power of my group is right; whatever lessens it is wrong.
  • Whatever hurts the people I hate is right; whatever doesn’t hurt the people I hate is wrong.

The terrible simplicity of such answers has very often been the basis for the most obscene crimes and atrocities in human history. And, unfortunately, those who reduce all of life to a simple question of whether they’re getting their way or not prevail more than we would like to admit.

We are confronted on a daily basis with assertions of fact, statements which claim to be “true” in the sense that they are, presumably, empirically demonstrable. We are presented with claims of evidence, claims that such-and-such an event occurred in real time at a real place. We have to make decisions about what we believe to be truly real. We are faced with the existential question, therefore, “What is true and what is false?” Upon this question rest whole belief systems and ideologies, as well as the related issues of whether we can even reliably ascertain answers to such a question. We are forced to define what we mean by “true” and “false”. How have people gone about doing so?

Throughout human existence, people have generally thought that whatever they perceived with their own senses was true. “I saw it with my own eyes” is considered conclusive proof to most of us. As far as the truth of larger things is concerned, there have been other methods employed. In most societies of the past, for example, the test of whether something was true or not was simple: do those with the ability to contact the supernatural plane of existence say that it is? If those believed to have this power passed a judgment on such a question, it was generally considered authoritative. There are gods, there is a soul, there are gods that weigh the soul in the balance after death, there is a sacred river we cross only in death, there are sacrifices which must be made to placate the gods, things can come alive again after dying, and all manner of such beliefs have been accepted as true because those with specialized knowledge of the metaphysical said so. Until a few hundred years ago this was considered the most powerful standard of truth in the vast majority of human societies.

But there have been, for many centuries, those for whom religious authority was insufficient. Some 2,500 years ago, on the eastern shore of the Aegean Sea, a small group of thinkers began the attempt to ascertain the truth or falsity of things through argument and the employment of reason, rather than by recourse to spiritual or mythological explanations of the world. In Asia, various thinkers looked beyond traditional faiths and began the search for what they considered to be the “essence” of reality, employing meditation, observation, and their own reasoning to find this essence. In each region, thinkers influenced each other, challenged each other, blended their ideas together, and created syntheses of ideas and standards of judging truth or falsehood. It was a revolution in human thinking, and it was to have massive consequences. It helped spawn the massive intellectual enterprise of science, which eventually was to transform the world and provide a systematic way of analyzing (within the limits of human ability) the nature of the reality with which humans were indirectly connected. But for most people, their own experience, and the role of authority continue to be paramount in their understanding of truth and falsehood, and that situation is likely to continue for the foreseeable future. They may respect philosophy and science, but they aren’t necessarily ready to accept their findings as the last words on an issue which most of them feel is connected to their eternal fate.

And then, there is the question that has, perhaps, caused more anguish and despair than any other: Why is there suffering? Often it is in our darkest and lowest times that we tend to ask this, when the issue of suffering is confronting us in the most direct and harrowing way possible.

In the chapter entitled, “Rebellion” in Fyodor Dostoyevsky’s immortal The Brothers Karamazov, one of the brothers, Ivan, a depressed intellectual, is discussing with his brother Alyosha, a gentle, Christ-like Russian Orthodox monk, the question of why God allows suffering. In particular, Ivan is tormented by the issue of the suffering of children, and he inundates his brother with horrible details of atrocities and abuses committed against children, which he has collected in the form of newspaper clippings and other documentation. One of the cases of abuse Ivan shares with Alyosha is a particularly hideous one involving the barbaric treatment of a five year old girl by her own parents. Ivan explains that the little girl, while locked in a stinking, freezing outhouse in the winter, was heard praying to God, asking Him what she had done to make her parents punish her so terribly. Then he adds:

“Can you understand why a little creature, who can’t even understand what’s done to her, should beat her little aching heart with her tiny fist in the dark and the cold, and weep her meek unresentful tears to dear, kind God to protect her? Do you understand that, Alyosha, you pious and humble novice? Do you understand why this infamy must be and is permitted? Without it, I am told, man could not have existed on earth, for he could not have known good and evil. Why should he know that diabolical good and evil when it costs so much? Why, the whole world of knowledge is not worth that child’s prayer to ‘dear, kind God!’ I say nothing of the sufferings of grown-up people, they have eaten the apple, damn them, and the devil take them all! But those little ones!...I am making you suffer, Alyosha. I’ll stop if you like.”

“Never mind. I want to suffer too,” muttered Alyosha.

Ivan speaks for many of us—and so does Alyosha. (It is a measure of Dostoyevsky’s intellectual integrity, by the way, that he, a Christian, was willing to throw the strongest and most emotionally wrenching case at his own belief system.) Almost all of us wonder why those who have done nothing wrong so often suffer so deeply and horribly. It seems to offend some very deeply embedded notion of fairness in us. It literally doesn’t make sense in our way of thinking. There is no justice in it. There is no proportion. The effect seems utterly disconnected to the cause. And when the victims of suffering are helpless, innocent children, our minds can come close to the breaking point if we dwell on it too long. Our natural sense of empathy for children, and our evolutionarily-conditioned protective instincts, are outraged by the pain and fear of “those little ones”. More broadly, we often wonder how a just and righteous God can look on such things, apparently, and do nothing. It is the ultimate problem for many religious believers, as they see not just children but all kinds of unoffending humans going through unspeakable tortures and devastating sickness. As one grows older, and there continues to be no apparent, predictable pattern that this suffering follows, our faith can be tested to its limits. Paradoxically, it is just such testing that can cause many to cling to their faith even more fervently: it is their last defense against the idea of a world of random, senseless, chaotic horror. Such people must believe that God or the Universe or the Supreme Intelligence has its reasons, and that someday the believers will understand those reasons. No other psychological position is tolerable for them.

The issue of suffering can be thought of as part of a broader question, and can indeed cause it to be asked: Why do evil and injustice exist? So often in history the brutal, the merciless, the cruel, and the morally indifferent have triumphed. So often the most terrible humans have lived to a ripe old age and died peacefully in their sleep while their countless victims had met their ends writhing in agony. So often the lawless and violent seem to prosper in life today, and barbarism is the norm in many, many places. (This may be part of the reason so many people want to believe in hell; they need to believe that the evil will be punished somehow, even if they escape the judgment of this world.) If God (or the Universe, or the Supreme Intelligence) is really the author of everything, is it the author of evil as well? Why does a purportedly all-powerful being even permit such a thing to exist? There is, in fact, an entire branch of theology devoted to this question, called theodicy. Religious thinkers have wrestled for centuries with the problem of evil. The best they have been able to do is to argue that God is so powerful that He or It can wrest good even out of apparent evil, or to argue that what seems evil to humans is not necessarily evil to a Being who has a plan for the evolution of the whole Universe. To many humans, such explanations are cold comfort, at best. Again, for their own mental well-being, they must believe that what is apparently evil has some larger purpose, and that in the end everything will make sense.


VII

Two of the final existential questions humans confront, in some form, are deeply intertwined: Is life worth living? and Is there such a thing as meaning, and if so, is it discoverable? In what ways can these issues be approached?

At the beginning of The Myth of Sisyphus, in the section entitled, “An Absurd Reasoning”, the existentialist writer and philosopher Albert Camus startles us with his opening lines: “There is but one truly serious philosophical problem, and that is suicide. Judging whether life is or is not worth living amounts to the fundamental question of philosophy.” (P. 3) To Camus the dilemma a human faces is justifying his or her existence in a Universe that is absurd, one apparently without purpose and one in which hope is illusory. Camus asserts that belief in the transcendent, and thus the hopeful, is an illogical leap of reasoning, a sort of intellectual desperation, an attempt to hold off a conclusion that would render human life meaningless. In reply to the hopes for the existence of the transcendent, Camus writes:

I don’t know whether this world has a meaning that transcends it. But I know that I do not know that meaning and that it is impossible for me just now to know it. What can a meaning outside my condition mean to me? I can understand only in human terms. What I touch, what resists me—that is what I understand. And these two certainties—my appetite for the absolute and for unity and the impossibility of reducing this world to a rational and reasonable principle—I also know that I cannot reconcile them. What other truth can I admit without lying, without bringing in a hope I lack and which means nothing within the limits of my condition? (P. 38)

To Camus, the limitations inherent in his human perspective preclude the possibility of ascertaining meaning. And yet, this does not mean for Camus that suicide necessarily follows as a rational course of action. On the contrary, humans must revolt against the absurdity of life by confronting it, by living as fully as possible, accepting the inevitability of one’s fate without being resigned to it. Camus believed that humans can be “indomitable and passionate”, throwing themselves into life totally. “The absurd man can only drain everything to the bitter end, and deplete himself.” (P. 41) It is in this revolt, this refusal to stop engaging the world, this refusal to be reconciled to it, that Camus found his purpose for living.

Most people probably don’t approach these questions from the standpoint that Camus did, but they encounter them nonetheless. Is life worth living? Let’s pose two diametrically opposite cases. If a human has those whom she loves, and who love her in return, is emotionally invested in the wellbeing of her  family and friends, has work that is enjoyable and useful, has frequent periods of joy, and holds out hope that reality will someday make sense to her, those reasons alone can be sufficient for living. But if a human is in constant despair, without family or friends, without joy, without meaningful work, without hope, and, most tragically, suffering from intractable pain or illness, the continuation of life may not make sense to him. Personal annihilation might appear to be the most rational choice in his situation. But in real life, the choices aren’t usually as clear cut as these examples might suggest. Humans may alternate between periods of enthusiasm for, or at least tolerance of, life, and periods where they think, “This just isn’t worth it.”. Virtually no one is entranced with life on a constant basis, but most of us find the prospect of personal annihilation unthinkable and troubling. Humans live somewhere in the gray, not easily defined middle of life, muddling through, and continuing onward through inertia and habit as much as conviction.

Is life worth living? To many people, it is worth living because they are obliged to do so—they have responsibilities, which in good conscience they cannot abandon. Is life worth living? To some it is because they have personal challenges and goals with which they are preoccupied, even obsessed. Is life worth living? To some, to abandon their lives would be to do something they cannot do—quit in the face of adversity and admit defeat. Is life worth living? To many of us, the answer is simple—as long as we have and know love, it is, despite all hardships.

What do humans mean by their search for “meaning”?  Here I am not talking about the interpretation of language, although meaning in language is certainly important. Here, I mean a question which in many ways is a summation of all the others. When we consider the meaning of existence, we are asking, What was all this for? If reality is the result of the will of a transcendent being, what was that will? Why does existence exist? Is there a logical reason for it, and is it aiming at some final condition, some ultimate state that must necessarily follow from its unfolding? Was there a reason we had to go through all the frequent misery that we had to endure? Most of us hope that there is some reason for all of our adversity and for existence itself. We want the story to have a satisfying conclusion, one that will resolve all our doubts and answer all of our questions.

Some have come to the conclusion that physical reality is the result of wholly natural processes, and if there is a meaning to all of this, it is far beyond our ability to discern it. To the question, is there such a thing as meaning, they might say no, and in fact they might go so far as to say that even the act of posing such a question is nonsensical. Others might reply that they don’t know what the ultimate “meaning” of the Universe’s existence is. They might add that the only real meaning they can know is that which they make for themselves, and that in the absence of certain knowledge, this is the best they can hope for. And we must ask, honestly: in a Universe in which we are so obviously insignificant, can any meaning ever be ascertained at all?

At last, the question of life’s meaning is, for most people, intimately connected with their attitudes toward death and what might come after it. The question What happens when people die? is of tremendous interest to most of us, even if the contemplation of our own demise is unsettling. The inevitability and seeming finality of death have been the subject of more speculation and discussion than perhaps any other existential question humans face. Death is a major concern of most of our religions, a major theme in our art and literature, a major subject for our philosophers, and a significant topic in the sciences. Few subjects are studied by such a breadth of disciplines. And few subjects compel our attention so strongly. It appears that the majority of the human race believes that death is not the end of the individual ego’s existence. Most humans believe in some sort of afterlife where the personality continues, or that a process of rebirth or transmigration takes place, where some essential part of the human is preserved to exist in different forms. Of course, every human who believes in these possibilities has his or her own vision of what this afterlife or rebirth might be like, and many believers have, throughout their lives, varying degrees of certitude about post-death survival.

For many humans, the idea that there might be no afterlife is intolerable. Why? First, because the idea of our non-existence terrifies many of us. After years of being, in effect, our own little Universes, it is inconceivable for many of us to imagine these Universes disintegrating into nothingness. The feeling might be described as I AM; how could I not be? For other humans, if there is no hope of an afterlife, there is no hope, period. Life would be a meaningless, futile act of mere survival. If there were no afterlife, it would mean that all their loved ones who had died would be gone forever. There would be no joyous reunions, no embracing of lost parents or lost children, no prospect of being reunited with those whose passing was made less painful only by the prospect that the separation would not be permanent. Most people simply cannot face this level of hopelessness. For others, the idea of no afterlife is intolerable because it would mean, ultimately, that there is no justice in the Universe. It would mean that the virtuous are unrewarded; that those who have undergone terrible suffering will not find the compensation of eternal comfort and mercy; and that evil humans who have not been punished in life get off the hook, so to speak. Many people simply cannot believe in such injustice. And for some, no afterlife means that there is no resolution to the personal issues and problems with which they may have struggled all of their lives, and no answers to questions that have disturbed them almost as long. Many people cannot abide such a lack of resolution. For a lot of humans, a combination of these beliefs is at work. There are those who also might look forward to the afterlife as a vindication of their faith and the prospect of being united with the One, the Sacred, the Almighty, the Divine. Little wonder so many humans have, still do, and always will believe that death is not the end.  They might even believe because they embrace a version of Pascal’s Wager: If they believe in an afterlife, and none exists, they won’t be aware of it, and will be none the worse off. If they don’t believe in one, and one exists, then the consequences of their disbelief might be grim indeed.

For those who do not believe in an afterlife, on the other hand, it can stir in them the urge to live as intensely as they can within the time they have. If our time truly is finite, then what is aspired to must be achieved in the here and now. There will be no second chance, in this perspective. Experience must be seized; life must be encountered. Conversely, some who have no faith in an afterlife might be morose, convinced that the only true proposition is, “Life is hard and then you die.” To such people, life might not seem only meaningless—it might seem not even worth the effort.

We do not encounter these existential questions in nice, orderly sequence, nor do we encounter them in neat, easily discernable, clearly marked situations. We encounter them in the flesh and blood world of everyday life in ways that are often muddled and filled with contradictions. We might never ask ourselves any of these questions in straightforward language, even if we sense their presence; they may always simply be undefined feelings deep within us, never examined in any serious way. And most disturbing of all, even if we do confront them directly, we may never find answers that satisfy us. The existential questions of life can pose challenges that perhaps we are not equal to. If we cannot be certain about why humans exist, what is right and what is wrong, or whether death is the end or not, we might be filled with unease and a sense of incompleteness, as if important business had been left undone. The way a human deals with the questions of existence tells us important things about them. Those who never think about these issues are personifying Plato’s famous quote: “The unexamined life is not worth living”. Those who believe they have all the answers to them may actually be arrogant and self-deceived. And those who seek answers in an open-minded way, modestly, and with a sense of humility, may be better positioned in  life than most people.

We were summoned into the world through an act that was not willed by us. As infants, we exist and perceive but we do not understand. We find ourselves thrown into a family (or some other group of caregivers). We find ourselves immersed in a particular way of life, which we come to assume is normal. We float in the river of time and we see the days pass in succession, not realizing what time itself is. We find ourselves in a particular historical era, although we are utterly unaware of this for many years. We are selves, being shaped by impulses, experiences, actions, reactions, personalities, and circumstances the nature of which we do not comprehend, but we cannot yet step outside of these selves to examine all of this. We interact with others, and we gravitate back and forth between the exterior world of this interaction and the interior world of our emotions, memories, impressions, and hypotheses about this interaction, the inner world of our emerging consciousness, the place in our brains where we process and absorb experience. This is our common inheritance as people, the reality each of us faces.

As we grow, and more and more see ourselves (usually) as a part of something larger than just us, we come to realize that the world is huge, life is complicated, that we don’t always understand what happens to us, other people can be challenging or frightening to deal with, and that much of existence just seems to be downright mysterious. Every human who has ever lived has, in my view, lived a version of this same story. Every human has found himself or herself in a world that was in many ways beyond their comprehension, but in which they were nonetheless forced to act and gather information.

Now let us remind ourselves that in addition to these personal challenges, that the following things appear to be true:

--Humans live in a frame of reference that they cannot escape and which prevents them from touching the Ultimately Real.

--Humans find themselves living in a Universe in which they are absurdly insignificant both spatially and temporally.

--Humans find themselves confronted by questions that they cannot always answer, or even formulate clearly, but which seem to be of the utmost significance, and which appear many times to have no certain answers at all. They are forced to seek answers to these questions with limited knowledge and restricted understanding—and they will never have anything else.

Moreover, the only tenuous links these humans have to the world outside of their own heads are forms of communication which by their very nature are imprecise and approximate. Humans are trapped in a reality in which total mutual understanding is impossible, one in which their motives are often obscure or completely hidden even to themselves.

It is these frequently confused, physically vulnerable, often talented, mentally isolated, unpredictable, surprisingly resilient, incredibly adaptable, virtually incomprehensible beings who have made and experienced the history of the world ever since the line between really bright ape and really limited human was crossed in some forever-lost moment of the past. We are going to look for the reasons why these beings want answers to questions that are often unanswerable, and why they have evolved to want and need answers to the particular questions they do. We will seek to understand (in part) the reality in which we find ourselves, and how that reality came to be. It is to the search for answers to these questions that we will now turn, even as we realize that after all of our searching and all of our examination, that the answers may still elude us, as a butterfly gently hovers beyond the grasp of a fascinated two year-old.
