Abstract

Ludwig Wittgenstein’s _Tractatus Logico-Philosophicus_ is among the most ambitious and influential philosophical works of the early twentieth century, and in recent years it has again occupied a central position in discussions of Wittgenstein’s philosophy. Written in an austere and meticulous style, the _Tractatus_ addresses questions in the philosophy of language, logic, and metaphysics, and, according to its author, provides a solution to all the problems of philosophy. This Broadview Edition contains the original English translation by C.K. Ogden and Frank P. Ramsey, annotated and revised by the editor for improved accuracy and clarity. Appendices include important material by Gottlob Frege and Bertrand Russell, as well as excerpts from Wittgenstein’s other writings.
