Laws and Symmetry

by Bas C. van Fraassen

Overview

Metaphysicians speak of laws of nature in terms of necessity and universality; scientists do so in terms of symmetry and invariance. This book argues that no metaphysical account of laws can succeed. The author analyses and rejects the arguments that there are laws of nature, or that we must believe that there are. He argues that we should discard the idea of law as an inadequate clue to science. After exploring what this means for general epistemology, the book develops the empiricist view of science as a construction of models to represent the phenomena. Concepts of symmetry, transformation, and invariance illuminate the structure of such models. A central role is played in science by symmetry arguments, and it is shown how these function also in the philosophical analysis of probability. The advocated approach presupposes no realism about laws or necessities in nature.

Editorial Reviews

"The most readable of the recent literature in the emerging field....This book might be the exemplar chosen by faculty of introductory philosophy of science programs. Highly recommended for all library collections in the philosophy of science."—Choice

"A fundamentally important contribution to philosophy. It is van Fraassen's finest book. With tight, careful arguments he demolishes the more prominent philosophical analyses of laws of nature. His definitive attack on inference to the best explanation leaves that notion thoroughly discredited and without a shred of credibility....In a pioneering discussion he also shows that symmetry considerations cannot provide that 'something more' philosophers demand of laws. The book further advances van Fraassen's own epistemological views and enhances our understanding of the Semantic Approach to philosophy and its superiority to earlier syntactical approaches. Laws and Symmetry is one of the best works in philosophy of science this century."—Frederick Suppe, University of Maryland
