By Ludwig Wittgenstein
"The volume is full of thought-provoking insights which will prove a stimulus both to further study and to scholarly disagreement." — Alan R. White, Philosophical Books
"All students of philosophy will want to read it. What it contains is his notes on knowledge and doubt, written in the last year and a half of his life, mainly in answer to G. E. Moore's articles on these subjects."—British Book News
Written over the last 18 months of his life and inspired by his interest in G. E. Moore's defense of common sense, this much discussed volume collects Wittgenstein's reflections on knowledge and certainty, on what it is to know a proposition for sure.
