  Fifth, the modal skeptic's thesis that our intuitions are not to be trusted outside of ordinary life (or the milieu for which they evolved) seems to be at odds with the effectiveness of mathematics in particle physics, cosmology, and the like. The mathematical beliefs of early Homo sapiens were surely quite primitive (it is irrelevant for present purposes how much unconscious processing was done by the brain). Interestingly, natural theology has been compared with theoretical physics (Earman 2000). If this comparison holds up, it seems to tell against the present modal skeptical argument.
