Abstract
George G. Simpson (1902–1984) and Stephen J. Gould (1941–2002) were both engaged with the normative – i.e., social, cultural, political, and even ethical – consequences of their evolutionary theorizing. However, there is a normative point of departure between Simpson and Gould’s work in that regard that has received little attention. Yet, their motivations converge into a larger program of resistance and social protection from misconstrued and illegitimate overreaches of the biological sciences leading up to and after the peak of the modern synthesis.
