The Genius Within: Discovering the Intelligence of Every Living Thing

"The Genius Within" is a must read for the non-specialist interested in science. It is a thought provoking work; very speculative, but grounded in mainstream scientific fact and theory. I thoroughly enjoyed reading it...twice. It's a bit technical at times, so some familiarity with the science involved is recommended. Also, if you happen to be more interested in "intelligent" animal behavior as such, rather than in its biochemical, microbiological and systemic underpinnings, you may want to look elsewhere. In this book, the author explores the notion the "networks" underlie the phenomenon we call life, and that life is synonymous with the information processing - intelligence - they architect. We tend to think of intelligence as a unique feature of brains, our conscious ones in particular (he calls this "brain chauvinism"), but he contends that all life is intelligent, or at least as "intelligent as it needs to be", and sets out to prove it. In simplest terms, he defines intelligence as the ability to solve problems related to survival. This seems to run counter to mainstream evolutionary theory, where the survival of species is basically as matter of, well, "dumb luck". But the author views intelligence as a collective phenomenon firmly embedded within this framework; as an "emergent behavior" of large groups of highly interactive biological entities (Including sub-cellular enzymes) otherwise engaged in a contingency-driven, random struggle for survival. The architecture that endows such groups with "emergent properties" is called, for want of a better word, a "network" by the author. The details of what the author means by a "network" is closely argued and beyond the scope of this review. In general, a biological "network" is a large collection of "selfish", randomly interacting entities whose components are capable of two or more relatively stable, but reversible, states (more active/less active, faster/slower, stronger/weaker), and whose components can variously enhance or impede each other's status over time, resulting in a collective "energy landscape" patterned by forces impinging on the network. The former allows for basic information storage (the biological equivalent of zeros and ones), and the latter for collective information storage (pattern recognition/memory) concerning the environment, allowing the collective to respond to environmental stimuli in, ultimately, a manner conducive to its survival. Overall, the architecture of a "network" harnesses the random, contingent interactions of its constituents into the directed or, as the author would claim, intelligent actions we associate with life at every level of biological organization. The author spends much of the book "fleshing out" these and other abstractions, particularly with respects to interacting aggregates composed of things such as cellular enzymes, bacteria and somatic cells, what he calls "party networks" as opposed to "hard wired networks", though he does

As easy to read as a novel and just as enjoyable, it will forever change the way you see the world around you. It is one of those rare books that links together a number of more or less well known ideas and arrives at an extraordinary and inescapable set of conclusions. Thank you, thank you, thank you.

If you want to know why Darwin might be "needlessy nihilistic" and what is at the core of Vertosick's carefully built case to explain--nothing less than--the possisble meaning of everything, then check this out. I thought the beginning was a little tedious, but the pay-off for hanging in there with his carefully crafted case was well worth it. I've bought several copies to share with friends and have had many lively debates. Thanks Dr. Vertosick for your emergent property--it's marvelous!

This book is breathtaking in its scope and originality. I find it difficult to describe how important it is within a short review. This will just be a sample. The Genius Within is simply the best overview of biology, evolution and intelligence we have. Vertosick extends the neural network model to explain how all intelligent systems work. Intelligent systems include organisms, parts of organisms, and associations of organisms. His basic idea is that any system that processes information to maintain and preserve itself in competition with other systems must be considered intelligent. He shows how general the neural network model of intelligence can be, applying it to metabolic cycles in the cell, to concerted action by communities of cells, both loosely connected in colonies and tightly connected in multicellular organisms. The hard wiring of vertebrate nervous systems is shown to be a special case of this general paradigm. A key concept is that of the "party network." This is a wireless network like the one formed by conversations at a cocktail party. People spend various amounts of time with each other on the basis of their common interests. The differing levels of affinity between pairs of party goers plays the same role as the connection weights between neurons in a neural network. Each of the people at the party is connected with every other by the network of interactions that take place over time, but some are more strongly connected than others. The mobility of the neurons (people in this case) in initiating new connections (conversations) makes hard wiring unnecessary to the development of network structure in the group. You can show the network in action by having one person introduce a piece of controversial information to one other person at the beginning, then asking each of the partygoers what he thinks about the subject at the end. The metabolic processes of a cell form a party network of interacting enzyme and substrate systems. These systems are connected through the interchange of substrate and products. The result is a network that transforms a few simple substrate molecules into the vast variety of interconnected macromolecules that defines the structure of the cell. This is an example of intelligence working at the basic level of molecular biolgy. Vertosick shows how this model works for the combined action of bacteria in overcoming the effects of antibiotics, to the development of effective antibodies by immune systems, to the coordinated actions of social insects, and up through the evolutionary scale to the function of brains and nervous systems in vertebrates. Evolution itself is seen though the model to be a manifestation of intelligence in organisms that uses genetic variation as a problem solving tool. The genes themselves are not the source of evolutionary change, but the repository of genetic information used by the organism. Vertosick gives the example of cloning to illustrate the p

In my opinion, this is an important but complex book. Vertosick presents ideas based upon a sound, but I think, poorly referenced scientific basis. He explores how basins of attraction help us understand all levels of biology, from chemical / cellular reactions to the immune system to the brain. His basic model is that large collections of relatively simple parts can act in a network based upon Darwinian selection principles. For example, chemical reactions, directed by enzymes, are driven to find their most energy efficient solutions. The most successful reactions will dominate the rest. Vertosick details how his ideas apply to the cell, to the immune system and to the brain. I have read a lot of the groundwork material and so was prepared for concepts like basins of attraction, the general reader could have used a better notes or reference section.
