The Origins of Order
Author: Stuart A. Kauffman
language: en
Publisher: Oxford University Press, USA
Release Date: 1993
This monograph extends the basic concepts of Darwinian evolution to accommodate recent findings and perspectives from the fields of biology, physics, chemistry and mathematics. It explains how complex systems, contrary to expectations, can spontaneously exhibit degrees of order.

How did life start? Is the evolution of life describable by any physics-like laws? Stuart Kauffman's latest book offers an explanation-beyond what the laws of physics can explain-of the progression from a complex chemical environment to molecular reproduction, metabolism and to early protocells, and further evolution to what we recognize as life. Among the estimated one hundred billion solar systems in the known universe, evolving life is surely abundant. That evolution is a process of "becoming" in each case. Since Newton, we have turned to physics to assess reality. But physics alone cannot tell us where we came from, how we arrived, and why our world has evolved past the point of unicellular organisms to an extremely complex biosphere. Building on concepts from his work as a complex systems researcher at the Santa Fe Institute, Kauffman focuses in particular on the idea of cells constructing themselves and introduces concepts such as "constraint closure." Living systems are defined by the concept of "organization" which has not been focused on in enough in previous works. Cells are autopoetic systems that build themselves: they literally construct their own constraints on the release of energy into a few degrees of freedom that constitutes the very thermodynamic work by which they build their own self creating constraints. Living cells are "machines" that construct and assemble their own working parts. The emergence of such systems-the origin of life problem-was probably a spontaneous phase transition to self-reproduction in complex enough prebiotic systems. The resulting protocells were capable of Darwin's heritable variation, hence open-ended evolution by natural selection. Evolution propagates this burgeoning organization. Evolving living creatures, by existing, create new niches into which yet further new creatures can emerge. If life is abundant in the universe, this self-constructing, propagating, exploding diversity takes us beyond physics to biospheres everywhere.
Understanding Origins
The question of origins is inseparable from a web of hypotheses that both shape and explain us. Although origin invites examination, it always seems to elude our grasp. Notions have always been produced which seek to interpret the genesis of life, mind, and the social order, and these notions have all been found to be unstable in the face of theoretical and empirical challenges. In any given period, the central ideas on origin have had a mutual resonance, frequently overlooked by specialists engaged in their particular fields. The main purpose of this truly interdisciplinary book is the drawing together of contributions from biology, the cognitive sciences and the humanities into a joint exploration of some of the main contemporary notions which deal with the understanding of origins in life, mind and society. The book consists of four central chapters (on social organization, symbols and money, life forms and perception) followed by acute and perceptive discussions. The book arose from an international meeting held at Stanford University.
