Abstract: It may seem to require an extraordinary coincidence if the moral beliefs that have evolved under natural selection turn out also 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 Street, this Coincidence Problem represents a serious objection to meta-ethical realism. I identify a number of problems facing her argument, suggesting that the appearance of a problem is misleading: a commitment to a coincidence of this kind need not be unacceptable for the realist. Central to my argument will be an analogy between theCoincidence Problem and the Fine-Tuning Problem in the philosophy of cosmology.
