Abstract
By naturalized epistemology, I mean those views expressed by Nozick and Margolis among others who favor an evolutionary account of human rationality as an adaptive mechanism which is unlikely to provide the means for its own legitimation and therefore unlikely to produce a single set of rules or norms which are certifiably rational. Analyzing the likely relativism that stems from such a view, namely that there could be divergent standards of rationality under different historical or environmental conditions, I conclude that evolutionary epistemologies are unable to account for rationality as an experienced capacity on the part of human beings. After giving a few examples of what seem to me to be cases where we do experience a form of reason that appears antinomian, I challenge a naturalized view of mind to embrace and provide some sort of explanatory account of this kind of mental elasticity that it both seems to make room for and is certainly not unfamiliar to other philosophical perspectives such as that of Zen Buddhism.
