A companion to Wittgenstein’s Tractatus

"It is one of the merits of Max Black's Companion to the Tractatus that he emphasizes the continuity of Wittgenstein's philosophical development by frequent quotation from his later writings." New York Review of Books "Black's book is, in effect, two books in one, and each of them is very good. First, there is the useful Companion to the Tractatus: the store of information that anyone who picked up the Tractatus would want to have. . . . Second, there are the interpretive essays: always judicious, frequently illuminating. It is hard to see how [this book] could have been more complete." Philosophical Books
