Abstract

The basic thesis of Skyrms's book is that the nomic necessity of laws should be understood in terms of the ways in which laws are confirmed and applied rather than as some mysterious metaphysical or epistemological quality. Skyrms's account centers around the notions of resiliency, which is a measure of probabilistic invariance, and that of propensities, which he takes to be highly resilient probabilities that figure in laws of nature.
