Epistemological Advantages

This chapter argues that accepting modal normativism brings significant epistemological advantages. Those who aim to account for modal knowledge face the integration challenge of reconciling an account of what is involved in knowing modal truths with a plausible story about how we can come to know them, and the reliability challenge of explaining how we could have evolved to have a reliable faculty for coming to know modal truths. Recent empiricist accounts of modal knowledge cannot solve these problems regarding specifically metaphysical modal truths—leaving us with the threat of skepticism about large portions of metaphysics. However, by giving a different functional story, the modal normativist can develop a plausible response to the remaining versions of both of these classic problems for modal epistemology. Modal normativists can also respond to further worries parallel to those raised by Sharon Street’s evolutionary debunking arguments in meta-ethics.
