Was wittgenstein an epistemic relativist?

Abstract

The paper reviews the grounds for relativist interpretations of Wittgenstein's later thought, especially in On Certainty. It distinguishes between factual and virtual forms of epistemic relativism and argues that, on closer inspection, Wittgenstein's notes don't support any form of relativism - let it be factual or virtual. In passing, it considers also so-called "naturalist" readings of On Certainty, which may lend support to a relativist interpretation of Wittgenstein's ideas, finds them wanting, and recommends to interpret his positive proposal in On Certainty as a form of "internal rationalism." © 2009 Blackwell Publishing Ltd.
