From Library Journal

Complexity has its roots in the work of many scientists from several disciplines and has only very recently, with the establishment of an institute in Santa Fe dedicated to its study, begun to come into focus as an analytical theory. Lewin's book is written as a kind of scientific travelog; he goes from the San Juan Basin of New Mexico to rural southwest England to the rain forests of Costa Rica in order to interview some of the key figures of complexity, whose independent works have contributed to the development of what could become a unified theory of the life sciences. Whether studying cellular automata or the evolution of life on earth, these scientists have found that order naturally seems to emerge within dynamic systems, often from the very brink of chaos. Lewin's far-ranging treatment of the subject is quite different from that of Michael Waldrop's Complexity: The Emerging Science at the Edge of Order and Chaos ( LJ 11/1/92), which remains pretty much centered at the Sante Fe Institute. Of the two, Lewin offers the most vivid and engaging discussion of complexity for general readers.

4.0 out of 5 stars A fine SECOND book on Complexity, January 28, 2001

By	"smokey_joe" (USA) - See all my reviews

This review is from: Complexity: Life at the Edge of Chaos (Paperback)

The scope of complexity science is vast, encompassing many disciplines. This book focuses on how the new idea of complexity relates to biology by discussing the idea with many leading biologists of the day. Other reviewers were put off by the book's lack of definition of what complexity is, and the lack of resolution as to what terms such as "edge of chaos" mean. But that is exactly the point. These terms do not have clear definition today. Complexity is a very immature field, frequently pursued at the visceral level. It is hard to define what it *is*, but frequently easy to identify it where it exists. I can understand the other reviewers' concerns with the lack of definition, and can only suggest that because of the narrower focus (biology), this is an appropriate second book on complexity.

As a second book, narrowly focused on the question of complexity in biology, it is outstanding. Specifically, the question is one of how self-organization (complexity) relates to evolution and what this means for natural selection. Complexity is frequently talked up as the unifier of the sciences. Lewin takes a balanced approach, taking the time to talk to complexity theorists and understand their ideas, then talking to mainstream biologists to see how the ideas relate. His conclusion shows no inherent bias. Where other books on complexity show extreme (perhaps undue) enthusiasm, Roger Lewin's concusion is decidedly "wait and see". I found his insights to be on target and relevant.

I mentioned that this is a good second book. For an introduction to complexity, read John Holland's "Hidden Order". For a history of the Santa Fe Institute and some of the personalities there, read Mitchell Waldrop's "Complexity". Either or both of these would serve as an adequate introduction to this book.

5.0 out of 5 stars A Great Introduction to "Complexity", March 27, 2000

By A Customer

This review is from: Complexity: Life at the Edge of Chaos (Paperback)

This book was my introduction to the field of complex adaptive systems. The concepts it contains changed the way I view the world. Roger Lewin mixes an overview of the subject (as it is emerging) with brief biographies of the pioneers in complexity theory. His writing makes it accessible -- and at the same time, a very enjoyable read. Of the introductory books on the topic, this one is the best.

5.0 out of 5 stars A fine introduction and an interesting read, September 18, 2000

By	Dennis Littrell (SoCal) - See all my reviews (TOP 50 REVIEWER)    (REAL NAME)    (COMMUNITY FORUM 04)

This review is from: Complexity: Life at the Edge of Chaos (Paperback)

The science of complexity, a discipline unique to the computer age, was born of chaos and a growing sense that there is something amenable to scientific inquiry about complex systems that we are missing. Before we had the number crunching power of computers, complexity could not be explored because the many variables resulted in astronomical calculations.

In this revision of his book originally published in 1992, Roger Lewin explains what the science of complexity is all about through interviews with some of its most important practitioners (and critics) organized around some of the central ideas. As such this is both a fine introduction to the subject and an interesting read. Lewin includes 16 pages of photos of the scientists he interviewed captioned with a significant quote from each. He has added an afterword on the application of complexity science to business, and an appendix about John Holland, whom he dubs, "Mr. Emergence."

"Everything works toward an ecology" is an old dictum of mine. I have the sense that I came up with that myself, but I probably read it somewhere years ago. At any rate, what is being said here is that complex systems work toward a state of equilibrium near a transition phase, near "the edge of chaos." This equilibrium can be an ecology (Darwin's "tangled web"); indeed it can be the entire planet, as in the concept of Gaia in which "the Earth's biological and physical systems are tightly coupled in a giant homeostatic system" (quoting Stuart Kauffman on page 109).

A central idea is that "...large, interactive systems-dynamical systems-naturally evolve toward a critical state" (physicist Per Bak, quoted on page 61). These systems include weather, financial markets, piles of sand, and most significantly, ecologies, so that evolution itself is seen as shaped by the dynamics of complexity. Complexity is the "interesting" middle ground between order and the purely random, between the crystalized structure of ice and the Brownian motion of molecules. I had a curious sense of understanding when I compared these three states with positions at chess. First there is the even, static position, perhaps with bishops of opposite color in which no progress can be made, a drawn the inevitable result. Second there is the wildly chaotic position so complex that no one can completely calculate it, say the board after black takes white's queen knight pawn in the "poisoned pawn" variation of the Najdorf Sicilian. In between are the "interesting" positions in which one side might have a small advantage or there might be a dynamic balance of advantages, space versus material, for example, in which a startling combination might be hidden.

These states-"at the edge of chaos"-are seen here as analogous to the phrase transition states of matter, from liquid to gas, for example. The idea is that there is a naturally occurring property of the physical world that forces complex systems into stable, readiness states near the edge of transition. What is exciting is that these states, because they are so "ripe" for change can be influenced or manipulated into change with small resources. Out of complexity comes something that could not be predicted by an analysis of its individual components, an emergent property of the system. I would note that such a natural phenomenon would be attractive to those who believe in punctuated evolution (e.g., Steven Jay Gould) and to those who believe that social and political change typically comes suddenly and with great force.

Central to what complexity science is saying is that reductionism-which is the technique that has driven science to its present position of power and influence-is limited. "...[Y]ou have to look at the interactions as well as the parts," John Holland is quoted as saying on page 220. In other words, you have to take a holistic approach. However, the use of the word "holistic," a New Age shibboleth, is the just sort of thing that makes traditional scientists wince.

Consequently, complexity science is not without its critics who argue that the fundamental mechanism of complexity exists only in a mystical sense and is therefore anathema to mainstream science. Even its practitioners, such as University of Michigan "complexologist" John Holland, admit they are still searching for the fundamental mechanism of this new science. He is quoted on page 214 as saying, "Our present understanding is not much better than the child saying that Jack Frost explains the wondrous colors of autumn."

However most complexity scientists would say that the mechanism isn't mystical at all. It's just not understood yet. I would add that much of what we think we know about the world is based on relationships and phenomenon that we assume we understand, but really we don't. For example physicists say that gravity curves spacetime, but they don't say how it curves spacetime. Presumably gravitons do the trick, but they haven't been discovered yet! So it could be said that gravity is mystical. I like to compare this lack of understanding to the task of watching grass grow. (This also works for evolution.) Every day I look but at no time do I ever see the grass growing, yet after a while I know it has grown. It seems that it always grows when I'm not looking! By the same token we see the results of complexity, but we do not yet see the inner workings of the process. We may never see the process, but through complexity science we may yet understand it.
