In Praise of Anarchy, Part III

Laurent Chehere[Part I] [Part II]

Kropotkin worked within the framework of 19th century natural science, but his results are just as relevant today as they were then. Moreover, the accuracy of his insights is vindicated by the latest research into complexity theory. Geoffrey West, who was a practicing particle physicist for forty years and is now distinguished professor at the Santa Fe Institute, has achieved some stunning breakthroughs in complexity theory and the mathematical characterization of scaling of biological systems. Looking at animals big and small, from the tiny shrew to the gigantic blue whale, he and his collaborators were able to determine that all these animals obey a certain power law: their metabolic cost scales with their mass, and the scaling factor is less than one, meaning that the larger the animal, the more effective its resource use and, in essence, the more effective the animal—up to a certain optimum size for each animal. The growth of every animal is characterized by a bounded, sigmoidal curve: growth accelerates at first, then slows down, reaching a steady state as the animal matures.
