"The answer to this question, sketched in the first three chapters, is built upon the old insight, well known to economics, that our values and institutions are determined not simply by preceding causes but as part of a process of unconscious self-organisation of a structure or pattern. This is true not only of economics, but in a wide area, and is well known today in the biological sciences. This insight was only the first of a growing family of theories that account for the formation of complex structures in terms of processes transcending our capacity to observe all the several circumstances operating in the determination of their particular manifestations. When I began my work I felt that I was nearly alone in working on the evolutionary formation of such highly complex self-maintaining orders."
