Gould on Laws in Biological Science

Abstract

Are there laws in evolutionary biology? Stephen J. Gould has argued that there are factors unique to biological theorizing which prevent the formulation of laws in biology, in contradistinction to the case in physics and chemistry. Gould offers the problem of ’’complexity‘‘ as just such a fundamental barrier to biological laws in general, and to Dollo‘s Law in particular. But I argue that Gould fails to demonstrate: (1) that Dollo‘s Law is not law-like, (2) that the alleged failure of Dollo‘s Law demonstrates why there cannot be laws in biological science, and (3) that ’’complexity‘‘ is a fundamental barrier to nomologicality.
