From Kirkus Reviews
``Strenuous'' is how Nobelist (Physiology or Medicine, 1972) Edelman describes the difficulties readers will encounter as they ply their way through yet another texty analysis of what it means to be a mind. Like Stephen M. Kosslyn and Olivier Koenig (Wet Mind, p. 235) and Israel Rosenfield (reviewed below), he likes to use old words in new ways, to coin complex hyphenated forms, and in other ways to multiply the prolixity level. Indeed, the three volumes complement one another. All speak to the need to ground analyses of mental functions in brain biology; all abhor cognitive-science approaches that look to the computer as the model of how the brain works. Edelman's approach is based on his theory of neuronal group selection (``TNGS''), which says that groups of neurons compete in the course of brain development, with surviving groups subject to a second selection in which specific pathways and synapses are strengthened according to whether they yield good or useful outcomes to the organism. Finally, there are broad, reciprocal interactions across neuronal groups that yield numerous brain ``maps.'' These ideas mark an evolution of Edelman's earlier work in immunity and development, in which Darwinian selection also figured. Indeed, evolution is key to Edelman's thinking. He, like Rosenfield, sees the emergence of a primary consciousness (possessed by birds and mammals?) rooted in the present and a high- order consciousness (and self-consciousness) occurring in humans as the result of the development of language. Edelman's many allusions to pivotal thinkers in philosophy and science enrich the historical context of his discussions. In the end, however, even he admits the daunting nature of the challenge. How to deal with logic, art, creativity, motivation, emotions? How to relate the importance of social interaction in development and throughout life? We can not yet, and perhaps never will, eliminate philosophy or psychology from the discussion. -- Copyright ©1992, Kirkus Associates, LP. All rights reserved.

From Library Journal
Edelman, Nobel laureate and director of the Neurosciences Institute, is the author of three previous books on the biology of the brain. His latest book advances the theory that the mind has arisen through evolutionary morphology. According to Edelman, the mind is not a kind of computer but a product of the biological forms that have developed through natural selection. To support his theory, Edelman offers a mini-course in modern molecular biology and development. By the author's own admission, this is "strenuous" reading, complete with "strange vocabulary." Nevertheless, Edelman presents his theory with enthusiasm and a genuine desire to discover the origins of the mind. Readers well-grounded in physics, biology, and philosophy will find his ideas extremely challenging. Primarily for academic libraries.

More than a quarter of a century ago, Edelman was distinguished with a Nobel Price for his research on the immunity system. Later he switched to neurology. He sees a parallel between the way the immunity system is programmed and the way the brain is programmed. These procedures have much in common with Darwins process of evolution by way of natural selection. Edelman speaks of "neural Darwinism".
When you just think about it, after reading the arguments Edelman brings forward, you will see that evolution could hardly have produced something as complex as the human brain (or even more simple animal brains) by any other means. A lot has to be investigated yet, of course, but I think Edelman has shown the way to a deeper understanding of our brain.
It is a pity Edelman and Daniel Dennet get along so badly. Edelman never mentions Dennet, and Dennet is extremely critical in the few remarks he makes about Edelmans work. I think their approaches are complementary, not contradictory.
Yes, the human brain is a computer of sorts. Edelman has the clearest ideas about the structure of this computer, but he denies that the metaphor of the computer is valid. I think that, even taking Edelmans ideas about the deeper structure in account, the metaphor remains valid, up to a point at least. Really, Edelman has much more in common with Dennet (whom he seems to despise) than with the "mysterian" Searle, whom he praises.

In Bright Air, Brilliant Fire, Gerald M. Edelman accomplishes what seems to be an almost impossible task: He helps the non-scientist to understand the connections between what is known about the mind with what is beginning to be known about the brain. For Edelman, this subject "is the most important one imaginable" because it is charged "with the excitement of being on the threshold of knowing how we know." At the outset, he poses "some commonsense notions":
1. Things do not have minds.
2. Normal humans have minds; some animals act as if they do.
3. Beings with minds can refer to other beings or things; things without minds do not refer to beings or things.
The book is divided into four main parts (Problems, Origins, Proposals, and Harmonies), concluding with "Mind Without Biology: A Critical Postscript" in which Edelman dispels the notion that the mind can be understood in the absence of biology. Stated another way (in Chapter 2), "There must be ways to put the mind back into nature that are concordant with how it got there in the first place."
Obviously, this is not a book for browsers, for grasshoppers, or for dilettantes. It makes great demands on the mind (and patience) of its reader. But consider Edelman's original objective: to explore the connections between what is known about the mind with what is beginning to be known about the brain. For him, this subject is (to reiterate) "the most important one imaginable" because it is charged "with the excitement of being on the threshold of knowing how we know."
Is there any other knowledge of greater importance?

Edelman's detailed reasoning may be beyond the abilities of a layperson to follow, but his concepts are clear and logically sequenced. Single cells communicate internally by diffusion, multi-celled organisms need specialist linking cells from one remote part to another because diffusion through successsive cell walls is too slow. Hence the beginning of a neural net. Evolutionary pressure gives a benefit from storing records of responses to stimuli in a specialist area of this net, access in due course to these records give Primary Consciousness. As a consequence of homo sapiens' upright gait, a unique construction over the windpipe to prevent food falling into the lungs coincidentally allows a far greater range of noises to be made in response to stimuli - enough different noises for a very fine degree of specialisation. Not merely "woof woof" = danger but "tree falling" = specific danger. A data store of the words associated with the responses permits them to be called up separately from the occurrences that crteated them - hence an ability to imagine and plan with Higher Consciousness. An interesting idea associated with this developmental scheme is that many animals (up to, say, lobsters) may have no consciousness at all and are merely machines. Better minds than mine may say that Edelman's details do not stand up to rigorous examination, but the concepts form the most persuasive explanation of consciousness that this reader has come across.
