"This anthology establishes the existence of a distinct and important post-Investigations Wittgenstein, uncovering the overlooked treasures of the final corpus and crystallizing key perceptions of what his last thought was achieving. Speaking of a 'third Wittgenstein', this book seeks to correct the traditional bipartite conception of Wittgenstein's thought into his Tractatus and Philosophical Investigations by focusing on his neglected last masterpiece, On Certainty, and works contemporaneous with it: Remarks on Colour, Last Writings in the Philosophy of Psychology, and Remarks on the Philosophy of Psychology. Leading international Wittgenstein scholars reveal why On Certainty should be recognized as one of Wittgenstein's three great works."--Jacket.
