Figments of Reality: The Evolution of the Curious Mind (Paperback)

A short chapter on free will is interesting but ultimately somewhat disappointing because the authors seem to be sitting on both sides of the philosophical fence. Recognizing that the assumption of free will is necessary for the orderly functioning of any culture and scornful of the inflated claims of genetic determinists, they note that theoretical reasons can be imagined for anything that occurs. To me, at least, this is as true as it is unconvincing. It is always possible to cobble together some sort of explanation of whatever transpires after the fact. Does this imply that the future is determined by the present? What might such an assertion mean? This chapter ends with the statement: ``Therefore free will is not just an illusion: it is a figment rendered real by the evolutionary complicity of mind and culture'' (p.241). Maybe I am dense, but this doesn't mean much to me. Perhaps the authors would have been wiser to omit this chapter, admitting that they do not know what free will is.
Two final chapters deal with some of the details of our many interactions with the surrounding culture, noting that a very large amount of knowledge is presently available to us all through libraries, schools, theater, television, and more recently the World Wide Web. The first of these chapters, entitled Extelligence, considers in some detail the ever increasing pool of information in which we are embedded in by our technological culture. The authors consider their notion of extelligence to be somewhat different from (say) Karl Popper's World 3, because it involves complicit interactions with individuals in a culture. This is, in my view, such an extremely important aspect of the overall subject of consciousness studies, that it deserves a book of its own. Perhaps the authors will team up with an informed and imaginative ethnologist in the not too distant future and work on such a project. The last chapter - entitled ``Simplex, Complex, Multiplex'' - describes the relationships between the organization of biological cells and human social systems. From this perspective, the village is analogous to a bacterium, whereas a town is compared to an eukaryote, and a city to a multi-celled organism. The chapter title alludes to increasingly sophisticated ways that individuals have of perceiving the intricacy of their social environments in a human culture.

The British authors of this book are a mathematician and biologist pair who boldly tackle these classic questions in philosophy with some original approaches. Maintaining that life, consciousness, and culture cannot understood by reducing them to the material elements from which they arise, the authors deftly develop a set of interesting concepts. Some of these are not especially original, but they are presented in an unusual light particularly as the authors ably illustrate them with very accessible descriptions of complex biochemical pathways of living matter.

A key concept is that of emergence - well established in philosophy and roughly equated to the popular idea of the whole being more than the sum of its parts. The authors couple this concept with one of their own - complicity, or the interaction of different things which lead them to become entirely new things. A third, among several others, is that of extelligence which arises from the interaction of the intellegences of individuals and is rooted in human culture. Using these and other concepts, the book, which is at the nexus of science and philosophy, seeks to explain how life, consciousness, culture, and reality arise and the relationship between them.

Be prepared to wade through these pages slowly to enjoy the masterful exposition of this book. Or, if you find this tedious, enjoy the elegant prose which uses the lens of science and philosophy to describe events which we might normally frame in different language. In the four-page prologue, a graphic sequence of events unfolds which chart the creation of the universe to the emergence of the symbolic literary creatures which constitute the human species: QUOTE Fifteen thousand million years ago the universe was no bigger than the dot at the end of this sentence......today, the two descendants of those tiny creatures are busy delineating their own limited version of the entire story in strange, angular geometric symbols impressed in contrasting pigment upon sheets of impressed white vegetable matter. UNQUOTE

Having long forgotten more than half the courses I took in college, this book allowed me to relive and reinforce the pleasures of two wonderful philosophy seminars - on theories of mind and philosophy of science. Expect, if you get through the book cover to cover, to see the world a little differently from when you start at the prologue.

Ian Stewart and Jack Cohen are a biologist and a mathematician team who have worked together to write a book on evolution; and not just biological evolution either. They discuss the origin of life, intelligence, consciousness, concepts of reality, social order, cities, and global civilization all within a 299 page volume.

Each chapter is opened with a charming quote, usually drawn from the lore of the behavioral sciences, that illustrates in capsule the content of the chapter. My favorites were the woman scientist and her chimpanzee subject, the viper with its "dead snake" pose, and the parrot whose protest over going through a boring word list made his intelligence far more apparent than reciting the list ever could.

Addressed in these chapters were some pretty heavy duty concepts. It's not that I hadn't come across them before in my reading, but that the authors' approach was novel, at least to me. Their treatment of the statistics of evolution and especially their analysis of the "Mitochondrial Eve" hypothesis were particularly enlightening. Until they likened it to the opening and ending moves of a chess game, with it's myriads of potential moves between beginning and end, I had not given much thought to how misleading are the cladal diagrams of evolutionary trees. They point out that the reductionist view, that looks for a core and a root to everything, is misleading because it neglects the total picture of what is going on in the environment and the emergent aspects of the interactive parts.

In the instance of the mitochondrial studies, they point out that a breeding population would probably have been at least 100,000 individuals, and the theory of 1 Eve and 99999 Adams, doesn't make much sense. As they note, it's much more likely that there were 50,000 of each gender, some of whom carried a particular stretch of DNA. Pointing out that there is a difference between the descent of a molecular sequence and the descent of a species they write, "Possibly there did exist a Mitochondrial Eve, but she is not the Mother of Us All: she represents a particular molecular sequence for mitochondrial DNA, embodied in a population of women possessing the molecule, from whom all modern mitochondrial DNA molecules descend (p. 88)."

More intriguing still was their discussion of complicity, which is a synergy among constituent parts that gives rise to unexpected results, sort of the old saw "the whole is greater than the sum of its parts." They feel that this type of unpredictable interaction among complex variables is what has given rise to human consciousness and even to the group think that occurs in crowd behavior. As they write, "One of the universal features of complicity is the emergence of new patterns, new rules, new structures, new processes that were not present, even in rudimentary form, in the separate components (p. 245)." They note that a complicity between language and intelligence might have worked synergistically, in a lock step fashion, enhancing both characteristics and in combination with what they term "extelligence," the variously stored knowledge of generations of humans, may possibly have lead to consciousness and civilization.

In their comparison of cellular evolution and village/town evolution, they again appeal to a complicity among parts, in this case individuals-or more correctly among professions-that created towns from villages. As unspecialized bacteria specialized and commingled to form nucleated cells, the members of villages began to specialize and create a larger more resilient town and as that grew, cities.

The most unique concept they presented-at least not one I'd heard before-was the possible explanation for the god phenomenon. They suggest that someone, Abraham for instance, might have been impressed by the extelligence of the environment, that "something outside himself" that knew more than he did. As they write, "It is a very small step from 'There is Something out there' to 'There is a Being out there (P. 264).'"

Steven was right again. This is a wonderful book. It definitely gets one thinking along new channels.
