 Street actually casts her argument in terms of a “Darwinian dilemma” for realists, which centers around the following question: what is the relation between the evolutionary shaping of moral judgments and the independent moral truths posited by realists? (Street 2006, 109). As already noted, the best scientific accounts suggest that there would be no special relation here, even if such moral truths existed. But if there is no special relation between this evolutionary shaping and independent moral truths, then we would have no reason to trust our moral beliefs, which are as likely to be off-track as on-track, leading to moral skepticism. So the realist seems to face a dilemma: reject the best available science or lose all justification for our moral beliefs.
