This is a reprint of the second, corrected edition, which includes extensive revisions.

Accordingly, in this edition Professor Hacker has rewritten six of his eleven original chapters and revised the others to incorporate the new abundant material.Insight and Illusion now fully clarifies the historical backgrounds of Wittgenstein's highly differing masterpices, the Tractatus and the Investigations, and traces the evolution of Wittgenstein's thought. Hacker explains all of Wittgenstein's writings in detail, focusing on his critique of metaphysics, his famous "private language argument," and his account of self consciousness.
