Abstract

In a recent paper, Chris Haufe paints a provocative portrait of the late paleontologist Stephen Jay Gould. His principal aim is to resolve a “paradox” arising from a prima facie inconsistent pair of commitments: Gould believed that the biological facts could have been otherwise, and Gould believed that there are evolutionary laws. In order to resolve this paradox, Haufe makes two substantive claims: Gould was aware of the challenges that the Replay Thesis posed for a law-centered science of evolution, even early in his career, and Gould endeavored to meet these challenges by deploying the “species-as-particles approach.” In this paper, I put pressure on both of these claims. By examining the goals and methods of Gould’s first “nomothetic research program,” the science of form, I show that it does not fit the picture of nomothetic science that Haufe illustrates. Additionally, I show that no straightforward connection exists between Gould’s understanding of contingency and his adoption of the species-as-particles approach. I propose that Gould’s career can be usefully split into three periods, each of which employed a distinct strategy for establishing distinctively paleontological contributions to evolutionary theory.
