Abstract

This paper explores the question of how the epistemological thesis of fallibilism should best be formulated. Sections 1 to 3 critically discuss some influential formulations of fallibilism. In section 4 I suggest a formulation of fallibilism in terms of the unavailability of epistemically truth-guaranteeing justification. In section 5 I discuss the claim that unrestricted fallibilism engenders paradox and argue that this claim is unwarranted.
