The Conditional Fallacy and the Self-Thwarting Fallacy in Keith Lehrer’s Epistemology

Abstract

Analytic philosophers need to distinguish between what has been called the conditional fallacy and what might be called the self-thwarting fallacy. The paper explores the difference by illustrating how its neglect has obscured the evolution of Keith Lehrer’s theory of knowledge. The paper also considers how attending to the distinction helps to reveal new critical concerns regarding Lehrer’s treatment of knowing.
