Abstract

Rush Rhees, a close friend of Wittgenstein and a major interpreter of his work, shows how Wittgenstein's _On Certainty_ concerns logic, language, and reality – topics that occupied Wittgenstein since early in his career. Authoritative interpretation of Wittgenstein's last great work, _On Certainty_, by one of his closest friends. Debunks misconceptions about Wittgenstein's _On Certainty_ and shows that it is an essay on logic. Exposes the continuity in Wittgenstein's thought, and the radical character of his conclusions. Contains a substantial and illuminating afterword discussing current scholarship surrounding _On Certainty_, and its relationship to Rhees's work on this subject
