Evolutionary psychology and conceptual integration
T&C suggest the desirability of 'conceptual integration' - "the principle that the various disciplines within the behavioral and social sciences should make themselves mutually consistent, and consistent with what is known in the natural sciences as well". They observe that while such integration has flourished between physics, chemistry and biology, for example, there has been little integration between the natural sciences on the one hand and the social sciences on the other.
They suggest that the science of evolutionary psychology can provide a bridge. The information-processing mechanisms of the mind are created by biology, and play a large role in our social behaviour and culture. Evolutionary psychology makes explicit the part of the causal stream as a whole that connects the natural sciences to the social sciences.
