“Emergence” seems to be the latest buzzword among a new generation of holistic/systems-oriented theorists. I say a “new” generation because emergence theory is not new. It can be traced back to a similar movement in the latter 19th century. (The history of this earlier movement is described in a recent article of mine in the journal Complexity called “The Re-emergence of Emergence: A Venerable Concept in Search of a Theory.”)
Among the many problems with the current reincarnation of emergence is the fact that there is no agreement on how to define the term in such a way that you can recognize emergence when you see it. One theorist who has done a creditable job, however, is biologist Robert Reid in his new book, Biological Emergences: Evolution by Natural Experiment (MIT Press 2007). Reid focuses on increases in biological complexity that produce qualitatively new functional properties, and he identifies three broad categories of emergent phenomena: (1) symbiosis and associations, (2) physiological and behavioral innovations, and (3) developmental and epigenetic influences. Reid also makes a compelling case for the thesis that emergence as he defines it has played a major creative role in evolution.
So far, so good. But Reid also attacks neo-Darwinism and claims that natural selection has had little to do with “progressive” evolution – meaning the evolution of complexity over time. Its role is primarily confined to “stabilizing” the innovations that have arisen autonomously, he asserts. Here, I’m afraid, we part company.
I certainly agree with Reid’s critique of the neo-Darwinists. And I certainly agree with his basic argument that emergence has played a fundamental creative role in evolution. How could I disagree. My own “Synergism Hypothesis” is really about emergent complexity -- though my theory emphasizes the functional (bioeconomic) effects – and their evolutionary consequences -- rather than the causes of emergence and embraces other, non-emergent forms of synergy as well. And yet, there remains a huge difference in our views about the role of natural selection, and I suspect it is traceable to differences in our "ground-zero" assumptions (as I call them) about the nature of life.
When all of Darwin's rhetorical flourishes, and his gradualism, and other problems with his theory are stripped away, the heart of his vision, I believe, is his assumption that life is at bottom a contingent, often precarious phenomenon (a "struggle for existence") and that "earning a living" in "the economy of nature" is the fundamental challenge for all life forms. I like to call it a "survival enterprise." In other words, failure is always an option. And, given the fact that life is predominately pursued in collectivities (emergent systems), the evolutionary process is -- at every level of complexity -- quintessentially a "collective survival enterprise." Moreover, economic criteria are crucially important; there are always costs for emergent novelties, and the benefits must outweigh the costs. (That is why the functional synergies associated with emergence are so significant.)
When this assumption is put together with Darwin's other basic assumption, that functionally important variability is a rule in the natural world, this means that natural selection (broadly defined) is inescapable. That is, the variants in every generation are subject to "differential survival and reproduction" based on their functional differences. It may be that some, or all, or none, of these variants can "make the cut" in any generation, but being subjected to the test of fitness is unavoidable. And this applies to any emergent novelty as well. Reid himself speaks of "natural experiments," and "adaptation," and "adaptability," and "functionality" (physiology is all about functions, he points out), and "workability," and "does it work?" The question is, adaptable/functional/workable for what? The answer, of course, is for ensuring/furthering/enhancing the "collective survival enterprise" in a given environmental context. I like biologist Theodosius Dobzhansky's characterization (or was it Julian Huxley's?) of evolution as a process of "trial-and-success."
So, while I wholeheartedly endorse Reid’s critique of the gene-centered, neo-Darwinian (mutation/competition/selection) paradigm, with its emphasis on ecological competition and its abstract "gene pool" model of the evolutionary process, and while I think emergence is of fundamental causal importance in evolution, I think natural selection (broadly defined) is also a party to the process at every step. I like evolutionary biologist Ernst Mayr's short-hand description of evolution as a "two-step tandem process" -- meaning (1) functional innovations, from whatever source, coupled with (2) differential success/failure over time. To assume otherwise is to assume away the basic survival problem, I believe. (Much of this is discussed further in my most recent book: Holistic Darwinism: Synergy, Cybernetics and the Bioeconomics of Evolution.)
Thought for the day: To quote again the great 20th century evolutionary biologist Theodosius Dobzhansky: "No theory of evolution that leaves the phenomenon of adaptation an unexplained mystery can be acceptable."
An Introduction
In his path-breaking book, Beyond Reductionism (1969), the famed novelist and polymath Arthur Koestler remarked that "true innovation occurs when things are put together for the first time that had been separate." He was talking about synergy, of course, a phenomenon that is still greatly underrated and vastly more important even than Koestler imagined. I call it "nature's magic."
Synergy is in fact one of the great governing principles of the natural world; it ranks right up there with such heavyweight concepts as gravity, energy, information and entropy as one of the keys to understanding how the world works. It has been a wellspring of creativity in the evolution of the universe; it has greatly influenced the overall trajectory of life on Earth; it played a decisive role in the emergence of humankind; it is vital to the workings of every modern society; and it is no exaggeration to say that our ultimate fate depends on it. Indeed, every day, in a thousand different ways, our lives are shaped, and re-shaped, by synergy.
All of these grandiose-sounding claims are discussed in detail, with many hundreds of examples, in three of my books: The Synergism Hypothesis (McGraw-Hill, 1983), Nature's Magic (Cambridge University Press, 2003), and Holistic Darwinism (University of Chicago Press, 2005), as well as in many of my articles for professional journals. Some of these publications are available at my website: http://www.complexsystems.org/
The purpose of this blog is to provide a continuing update on synergy and an opportunity for some dialogue on this important and still underappreciated phenomenon, along with commentaries on various topics - political, economic, and social -- from a synergy-monger's perspective. The tag-lines for each entry, with a "thought for the day," are the unregulated firecrackers that go off in my mind from time to time.
