How to Supplement Mentalist Evidentialism: What Are the Fundamental Epistemological Principles?

Evidentialism and mentalism enjoy much popularity. In fact, mentalist evidentialism is often considered the most plausible internalist approach towards epistemic justification. However, mentalist evidentialism does not amount to a comprehensive theory of epistemic justification. In their attempt to complete their epistemological system and to answer the question of why experiences are justifiers, Conee and Feldman supplement mentalist evidentialism with explanationism. They take principles of best explanation to be the fundamental epistemic principles. In this paper, I show that explanationist mentalist evidentialism is plagued by severe shortcomings. What is more, I argue for an alternative in the spirit of Conee and Feldman's internalism that avoids the problems of explanationism, offering a straightforward commonsense account of epistemic justification. The fundamental epistemological principles are phenomenological principles.
