Abstract
What is a law of nature? Traditionally, philosophical discussion of this question has been dominated by two prominent alternatives; David Lewis’s best-systems analysis, according to which a law is a regularity that serves as a theorem in our best axiomatization of the facts about the world, and the Dretske-Armstrong-Tooley analysis, which incorporates universals to distinguish laws from mere accidental generalizations. Marc Lange’s first book presents a provocative alternative to this tradition, providing a novel treatment of natural laws that should be of interest to those philosophers concerned with the analysis of lawhood, physical necessity, causation, inductive confirmation, counterfactual analysis, and explanation.
