This author explores the intersection between cognitive science, as exemplified by the computational model of mind, and epistemologyo specifically, epistemic justification theory. Her analysis leads to the conclusion that some very specific and somewhat technical issues in epistemic justification theory can be at least partially resolved, if not entirely cleared up, by the use of the computational model. The third and fourth chapters of this work are devoted directly to that effort. Chapter one examines in detail epistemology and cognitive sciences, while chapters two and three offer a thorough introduction to standard epistemic justification theory. Finally, chapter five is a critique of the computational model.
