Abstract
Foundationalist epistemologies, whether internalist or externalist, ground noetic structures in beliefs that are said to be foundational, or properly basic. It is essential to such epistemologies that they provide clear criteria for proper basicality. This proves, 1 argue, to be a thorny task, at least insofar as the goal is to provide a psychologically realistic reconstruction of our actual doxastic practices. I examine some of the difficulties, and suggest some implications, in particular for the externalist epistemology of Alvin Plantinga.
