ABSTRACT
It may seem to require an extraordinary coincidence if the moral beliefs favored by natural selection turn out reliably to be true, given that matters of truth and falsity are irrelevant in accounting for the selection-pressures shaping human moral psychology. According to Sharon Street, this Coincidence Problem represents a serious objection to meta-ethical realism. The author identifies a number of problems facing her argument, suggesting that a commitment to a coincidence of this kind need not be unacceptable for the realist. Central to his argument is an analogy between the Coincidence Problem and the Fine-Tuning Problem in the philosophy of cosmology.
