 Absent such doubts, it’s not clear why the mere fact of historical evolutionary influence should undermine our confidence in our moral claims. To draw an analogy, should a theist give up her belief just because crude, ancestral forms of religious belief can be causally explained without appeal to theological facts? Perhaps she will if she finds no good reasons for her own belief, and concludes that it is to be explained along similar lines. But if she has reflected on the matter and been persuaded by a “cosmological argument from fine tuning,” for example, then it seems she might reasonably maintain her belief, taking her employment of the concept of a deity to be epistemically legitimate despite the fact that other employments are subject to debunking evolutionary, sociological and psychological explanations.
