Two fine authors, Richard Dawkins and Daniel Dennett, have written recent books, The God Delusion and Breaking the Spell arguing against religion. Their views are based on contemporary science. But the largest convictions of contemporary science remain based on reductionism. I would like to begin a discussion about the first glimmerings of a new scientific world view — beyond reductionism to emergence and radical creativity in the biosphere and human world. This emerging view finds a natural scientific place for value and ethics, and places us as co-creators of the enormous web of emerging complexity that is the evolving biosphere and human economics and culture. In this scientific world view, we can ask: Is it more astonishing that a God created all that exists in six days, or that the natural processes of the creative universe have yielded galaxies, chemistry, life, agency, meaning, value, consciousness, culture without a Creator. In my mind and heart, the overwhelming answer is that the truth as best we know it, that all arose with no Creator agent, all on its wondrous own, is so awesome and stunning that it is God enough for me and I hope much of humankind.

REDUCTIONISM [11.13.06]
Introduction Stuart A. Kauffman studies the origin of life and the origins of molecular organization. Thirty-five years ago, he developed the Kauffman models, which are random networks exhibiting a kind of self-organization that he terms "order for free." He asks a question that goes beyond those asked by other evolutionary theorists: if selection is operating all the time, how do we build a theory that combines self-organization (order for free) and selection? The answer lies in a "new" biology:
In the
following essay, Kauffman frames a new scientific world view of emergence
and ceaseless creativity, which, he notes, is "awesome in what
has come to pass in reality, and God enough for me and many, where
God is the creativity of the universe, yielding a global ethics of
respect for all life, the planet, awe, wonder and spirituality cut
free from a transcendent God." Dr. Kauffman
is also an emeritus professor of biochemistry at the University of
Pennsylvania, a MacArthur Fellow and an external professor at the
Santa Fe Institute. He is
the author of The Origins of Order, At
Home in the Universe: The Search for the Laws of Self-Organization,
and Investigations. |

REDUCTIONISM: REINVENTING THE SACRED In the West, those who hold to a view of a theistic God, including the Christian fundamentalists of such power in the United States, find themselves in a cultural war with those who do not believe in a transcendent God, whether agnostic or atheistic. This war is evidenced by the fierce battle over Intelligent Design being waged politically and in the court systems of the United States. While the battleground is Darwinism, the deeply emotional issues are more fundamental. These include the belief of many religious people that without God's authority, morality has no basis. Literally, for those in the West who hold to these views, part of the passion underlying religious conviction is the fear that the very foundations of Western society will tumble if faith in a transcendent God is not upheld. The majority of the Abrahamic peoples are Muslims. I know the Islamic world poorly, but believe that their fundamentalism again in part lies in these moral issues. Beyond that, reductionism, wrought by the successes of Galileo, Newton, Einstein, Planck, and Schrodinger, and all that has followed, preeminently in physics, has, as I will expand upon in a moment, left us in world of fact — cold fact with no scientific place for value. "The more we know of the cosmos, the more meaningless it appears", said Stephen Weinberg in Dreams of a Final Theory. For example, Wolfgang Kohler, one of the founders of Gestalt psychology, wrote a mid 20th century book entitled hopefully: The Place of Value in a World of Fact. And just a few days ago, a conversation with a humanist professor at the University of Pennsylvania astonished me with her account of how we are again a meaningless world in the post modern world view rampant in the North American humanities. On the other side of this vast divide than those who hold to a transcendent God and His authority for meaning and values, are the innumerable secular humanists, children of the enlightenment and contemporary science, who hold firmly to reality as revealed by science, find values in their love for their families and friends, a general sense of fairness and a morality that needs no basis in God's word. Yet we secular humanists have paid an unspoken price for our firm sense that (reductionist) science tells us what is real. First, we have no well wrought scientific basis for our humanity — despite the interesting fact that quantum mechanics on the Copenhagen interpretation assumes free willed physicists who choose what quantum features to measure and thereby change the physical world. The two cultures, science and humanities, remain firmly un-united. And equally important, we have been subtly robbed of our deep capacity for spiritualism. We have come to believe that spirituality is inherently co-localized with a belief in God, and that without such a belief, spirituality is inherently foolish, questionable, without foundation, wishful thinking, silly. In turn, we lack a global ethic to constitute the transnational mythic value structure that can sustain the emerging global civilization. We tend to believe in the value of democracy and the free market. We are largely reduced to consumers. Here it is telling that Kenneth Arrow, brilliant Nobel Laureate in economics and friend, took part in a commission to "place a value" on preservation of National Parks and was stymied in his attempt to find a way to calculate that value based on utility to citizens. Thus, even in our enjoyment of the wild, we are reduced to consumers in our currant Weltanschauung. Two fine authors, Richard Dawkins and Daniel Dennett, have written recent books, The God Delusion and Breaking the Spell arguing against religion. Their views are based on contemporary science. But the largest convictions of contemporary science remain based on reductionism. I would like to begin a discussion about the first glimmerings of a new scientific world view — beyond reductionism to emergence and radical creativity in the biosphere and human world. This emerging view finds a natural scientific place for value and ethics, and places us as co-creators of the enormous web of emerging complexity that is the evolving biosphere and human economics and culture. In this scientific world view, we can ask: Is it more astonishing that a God created all that exists in six days, or that the natural processes of the creative universe have yielded galaxies, chemistry, life, agency, meaning, value, consciousness, culture without a Creator. In my mind and heart, the overwhelming answer is that the truth as best we know it, that all arose with no Creator agent, all on its wondrous own, is so awesome and stunning that it is God enough for me and I hope much of humankind. Thus, beyond the new science that glimmers a new world view, we have a new view of God, not as transcendent, not as an agent, but as the very creativity of the universe itself. This God brings with it a sense of oneness, unity, with all of life, and our planet — it expands our consciousness and naturally seems to lead to an enhanced potential global ethic of wonder, awe, responsibility within the bounded limits of our capacity, for all of life and its home, the Earth, and beyond as we explore the Solar System. Reductionism Like any other world view, reductionism is hard to pin down. The modern world view of reductionism clearly grows from the success of modern physics, but finds its roots in ancient Greek philosophy, that all is made of earth, air, fire, and water, or from atoms. Roughly, reductionism is the view that, as Nobel Laureate Stephen Weinberg eloquently puts it, the "explanatory arrows always point downward", from society to small groups to individuals to organs to cells to chemistry to physics and ultimately to something like Weinberg's Dreams of a Final Theory, a single set of laws, elegant in their form, like General Relativity, which, in Weinberg's sense, explains all. A large majority of contemporary scientists are reductionists. If pressed, most would roughly say that the behavior of complex wholes is nothing more that the laws governing the behaviors of the parts and their interactions. An example well known in physics is the purported successful reduction of classical thermodynamics to statistical mechanics. Here temperature is equated with the mean kinetic energy of particles, pressure with the energy transfer to bounding walls, and the famous second law of thermodynamics is equated with a "flow" of an isolated thermodynamic system from less to more probable macrostates. I have used the caveat "purported" because — an issue too technical to go into here — the reduction requires the truth of the "ergodic hypothesis" and there is some evidence that it might be false. With reductionism comes the conviction that a court proceeding to try a man for murder is "really" nothing but the movement of atoms, electrons, and other particles in space, quantum and classical events, and ultimately to be explained by, say, string theory. Beyond Reductionism We begin with the growing doubt among many physicists themselves that reductionism itself suffices. Nobel Laureate Philip Anderson wrote a famous article, "More is Different", some decades ago, arguing that reductionism is wonderful, but not enough. A computer computing a complex algorithm can be made of transistors or water buckets — it is able to run on multiple physical platforms. Hence reducing the computer to any particular physical basis is insufficient to explain the computer. The drift away from reductionism among physicists is most pronounced among solid state physicists, who deal with such things as metals, glasses, spin glasses, and systems with many "broken symmetries". Robert Laughlin, solid state physicist and Nobel laureate, argues strenuously against the full efficacy of reductionism in A Different Universe. The physicists who hold out for a firm reductionism are, like Weinberg himself, largely high energy particle physicists, seeking that final theory — say string theory. But it is precisely in the province of string theory itself, that doubts are arising. The early hope was that a single string theory would be found that would explain quantum gravity and all the known particles and forces. Such a single string theory would be the answer to Weinberg's dream of a final theory. But at present, it appears that there are as many as 10 to the 500th power string theories. Hope for a single theory is fast fading and a number of high energy physicists are abandoning reductionism in the sense of finding such a single theory. Thus, Leonard Susskind, in the Cosmic Landscape, suggests a multiverse of "pocket universes", each with a randomly chosen string theory, and a landscape over these "pocket universes" with respect to those whose laws are life friendly. As a critical side note, part of Susskind's move is an attempt to explain the roughly 23 physical constants in physics like the speed of light, the ratio of electron to proton mass, and so on. No one knows where these constants come from or how to explain them. Weinberg himself uttered the "A" word — anthropic. According to this idea, there are many universes, and only those with constants that support the evolution of intelligent life would have such life to wonder at the values of the constants. In short, many, but not all physicists, are giving up on the adequacy of reductionism alone as a scientific principle to explain the properties of the world. In its stead a new scientific world view is just starting to come into view: Emergence. Emergence Roughly speaking emergence breaks into two sub-views, epistemological and ontological emergence. The former says that complex systems are too complex to be explained by reductionistic practices, but that ontologically, reductionism holds. The ontological view is that new entities with their own properties and causal powers arise and are part of the furniture of the universe. I hold strongly to this view and will present a number of cases that appear to support it.
The Biosphere and Human Culture are Ceaselessly Creative in Ways that Cannot be Foretold. The third, rather astonishing theme that is emerging in this new world view is that the biosphere and human culture are ceaselessly creative in ways that are fundamentally unpredictable and presumably non-algorithmic or machine like. I begin with Darwinian adaptations and preadaptations. Were one to ask Darwin what the function of the heart is, he would have replied, "To pump blood". That is, the causal consequence of the heart for virtue of which it was selected by natural selection is pumping blood. But the heart makes heart sounds. These are not the function of the heart. Thus, the function of the heart is a subset of its causal consequences and must be analyzed in the context of the whole organism in its selective environment. Again this says that biology cannot be reduced to physics, for while the string theorist might (actually could not) deduce all the properties of a given heart, he/she would have no way to pick out as the relevant property that of pumping blood. But it is that property that accounts for the existence of hearts in the biosphere. Now a Darwinian preadaptation is a causal consequence of a part of an organism of no selective significance in the normal environment, but which might be of use in some odd environment, hence become the subject of natural selection. Here the organ was "preadapted" for this novel function in the biosphere. A fanciful example concerns the squirrel Gertrude who happened to have a single Mendelian dominant mutant that gave her flaps of skin from arms to legs on both sides. (Darwinian preadaptations need not rely on new mutations in general, but I use them for my friend Gertrude, who lived 65,394,003 years ago in Guatemala.) Gertrude was so ugly that the rest of the squirrels would not play or eat with her. She was in a magnolia tree eating lunch sadly and alone when Bertha, an early owl in a neighboring pine, spied Gertrude, thought "Lunch", dived towards Gertrude horrid claws extended…..Gertrude was terrified. Suddenly she jumped from the tree, arms and legs flung wide. "Ghaaaa!" cried Gertrude, then looked, incredulous, as she flew. And she escaped the befuddled Bertha. Well, Gertrude became a heroine in her clan, was married in a lovely civil ceremony to a handsome squirrel not a month later, and thanks to her dominant mutation, all their children had similar flaps of skin. And that is how flying squirrels came to exist in the biosphere. I like Gertrude a lot. It is critical that virtually any extant feature of an organism can become the subject of natural selection in the appropriate environment, and typically, if selected, a novel functionality arises in the biosphere and universe. Now the critical question: Do you think you could say ahead of time, or finitely prestate, all possible Darwinian preadaptations of, say species alive now, or even humans? I have not found anyone who thought the answer was yes. I do not know how to prove my claim that the answer is "No", but part of the problem is that we cannot finitely prestate the relevant features of all possible selective environments for all organisms with respect to all their features. But the failure to prestate the possible preadaptations is not slowing down the evolution of the biosphere where preadaptations are widely known. Thus, ever novel functionalities come to exist and proliferate in the biosphere. The fact that we cannot prestate them is essential, and an essential limitation to the way Newton taught us to do science: Prestate the relevant variables, forces acting among them, initial and boundary conditions, and calculate the future evolution of the system…say projectile. But we cannot prestate the relevant causal features of organisms in the biosphere. We do not know now the relevant variables! Thus we cannot write down a set of equations for the temporal evolution of these variables. We are profoundly precluded from the Newtonian move. In short, the evolution of the biosphere is radically unknowable, not due to quantum throws of the dice, or deterministic chaos, but because we cannot prestate the macroscopic relevant features of organisms and environments that will lead to the emergence of novel functions in the biosphere with their own causal properties that in turn alter the future evolution of the biosphere. Thus, the evolution of the biosphere is radically creative, ceaselessly creative, in way that cannot be foretold. I find this wonderful. I believe this fact means that the evolution of the biosphere is non-algorithmic. It cannot be simulated, certainly with continuous spacetime and quantum mechanics playing a role. The same Darwinian preadaptations occur in the evolution of the economy. The story concerns engineers trying to invent the tractor. They would need a massive engine block. They tried it on chasse after chasse, all of which broke. Finally one of the engineers said, "The engine block itself is so massive and rigid that we can use the engine block itself as the chasse." And that is how tractors are made. Now the rigidity of the tractor was a Darwinian preadaptation, a causal feature useful for a new function. Its discovery was a true invention. But this means that the technological evolution of the econosphere is also not finitely prestatable, nor presumably algorithmic. It too is ceaselessly creative, expanding from some 1000 goods and services say 50,000 years ago to perhaps 10 billion today. And human culture, in general, is ceaselessly creative as the biosphere and culture expand into what I call the Adjacent Possible. Here the point is that, at levels of complexity above the atom, the universe has not had time to make all possible complex objects, such as all proteins length 200. The universe, at these levels of complexity, is on a unique trajectory. So when my friend Gertrude flew, she changed the material and behavioral features of the evolving universe. So did Picasso. In short, in wondrous ways, these our universe, biosphere, econosphere, and culture are ceaselessly creative and emergent. The two cultures, science and humanities, stand united in this world view. Meaning and value have a scientific base. And ethics? At a recent meeting on science and religion on Star Island, we heard more than one lecture on animal emotions and the sense of fairness in chimpanzees. Group selection, we were told, is now making its way into evolutionary biology. With it, natural selection can get its grip on behaviors that are advantageous to the group, like fairness, so it emerges. Far from evolution being anathema to ethics, evolution is the first source of human morality. But not the last, for we can argue whether we should want what we want. God and a Global Ethic God is the most powerful symbol we have created. The Spaniards in the New World built their churches on the holy sites of those they vanquished. Notre Dame sits on a Druid holy site. Shall we use the God word? It is our choice. Mine is a tentative "yes". I want God to mean the vast ceaseless creativity of the only universe we know of, ours. What do we gain by using the God word? I suspect a great deal, for the word carries with it awe and reverence. If we can transfer that awe and reverence, not to the transcendental Abrahamic God of my Israelite tribe long ago, but to the stunning reality that confronts us, we will grant permission for a renewed spirituality, and awe, reverence and responsibility for all that lives, for the planet. Does one know that such a transformation of human sensibilities will happen? Of course not. But the sense of justice matured in the Abrahamic tradition from 10 eyes for an eye, to an eye for an eye, to love thine enemy as thyself. Then can a heightened consciousness bring about a global ethic? I believe so. I believe, I hope correctly, that what I have sketched above is true, points to a new vision of our co-creating reality, that it invites precisely an enhancement of our sense of spirituality, reverence, wonder, and responsibility, and can form the basis of a trans-national mythic structure for an emerging global civilization. Co-Evolving Traditions To ever
succeed, this new view needs to be soft spoken. You see, we can
say, here is reality, is it not worthy of stunned wonder? What
more could we want of a God? Yes, we give up a God who intervenes
on our behalf. We give up heaven and hell. But we gain ourselves,
responsibility, and maturity of spirit. I know that saying that
ethics derives from evolution undercuts the authority of God as
its source. But do we need such a God now? I think not. Nor do
we need the spiritual wasteland that post-modernism has brought
us. Beyond my admired friend Kenneth Arrow, natural parks are valuable
because life is valuable on its own, a wonder of emergence, evolution
and creativity. Reality is truly stunning. So if you find this
useful, let us go forth, as was said long ago, and invite consideration
by others of this new vision of reality. With it, let us recreate
spiritual community and membership. Let
us go forth. Civilization needs to be changed. References: Anderson, P. 1972. More is different. Science 177:

Jaron Lanier [11.13.06] Am I getting old and jaded? I worry that in the matter of fundamental beliefs and worldviews, people as a whole. including me, are not to be trusted. To be cynical, I could point out that starting a new religion is the biggest business of all — so Stuart Kauffman might make scientists everywhere rich. The only problem is that people don't consistently have the discipline to avoid the slide into silly superstitions, no matter how carefully their underlying beliefs might have been constructed or vetted — Buddhism, which some claim to be the least dangerous religion, still served as the foundation of the beliefs of a group that released sarin gas in the Tokyo subways — and of course the major supposedly enlightened materialist movements of the 20th century (those referring to Marx) were moral disasters — someone will always show up to promote nonsense for short sighted gains. The best strategy for us humans is to have an interminable and endlessly confusing ecology of conflicting metaphysical or underlying beliefs — different religions — so that no single belief can become a powerful monoculture, which makes it hopelessly seductive to maniacs. How did the American founders manage to get that so right, so long ago? It's important to acknowledge what one believes instead of pretending not to believe in anything, which is almost always a form of self-delusion — in that spirit I'm ready to sign up for the beautiful new spirituality Kauffman is articulating — just so long as I'm not joined by absolutely everyone else, in which case I'd have to switch to believing in something else as a matter of survival for us all. |
