“In this book I try to show how models of self-organization can be applied to many economic phenomena - how the principle of "order from instability," which explains the growth of hurricanes and embryos, can also explain the formation of cities and business cycles; how the principle of "order from random growth" can explain the strangely simple rules that describe the sizes of earth quakes, meteorites, and metropolitan areas. I believe that the ideas of self-organization theory can add substantially to our understanding of the economy; whatever their ultimate usefulness, these ideas are very exciting, and playing around with them is tremendous fun.”

Context: It was very dispiriting because a lot of things needed to be done. One of the things that happened was, if you had a good rank-and-file activist in a trade union situation, they would make them an offer to become part of the staff—at which point the person was totally lost to the campaign where they were a catalyst and became part of an apparatus that was basically going nowhere. The odd thing is, despite The Permanent Revolution being on the bookshelves, they would explain everything by going back and finding a quote from Trotsky or from Lenin in order to explain things, as opposed to explaining how things were in the real world.... They were basically just living in their own universe as opposed to making real life connections.
