The commentaries are a promising sign that a research programme on the cognitive science of souls will continue to move toward empirical and theoretical rigor. Most of the commentators agree that beliefs in personal immortality, in the intelligent design of souls, and in the symbolic meaning of natural events can provide new insight into human social evolution. In this response I clarify and extend the evolutionary model, further emphasizing the adaptiveness of the cognitive system that underlies these beliefs.

Atran & Norenzayan's (A&N's) target article effectively combines the insights of evolutionary biology and interdisciplinary cognitive science, neither of which alone yields sufficient explanatory power to help us fully understand the complexities of supernatural belief. Although the authors' ideas echo those of other researchers, they are perhaps the most squarely grounded in neo-Darwinian terms to date. Nevertheless, A&N overlook the possibility that the tendency to infer supernatural agents' communicative intent behind natural events served an ancestrally adaptive function.
