Published just over a century ago, Wittgenstein's Tractatus Logico-Philosophicus is the only book-length work to have been published during his lifetime and it continues to generate interest and scholarly debate. It is structured as a series of propositions on metaphysics, language, the nature of philosophy, and the distinction between what can be said and what can be shown. This volume brings together eleven new essays on the Tractatus covering a wide variety of topics, from the central Tractarian doctrines concerning representation, the structure of the world and the nature of logic, to less prominent issues including ethics, natural science, mathematics and the self. Individual essays advance specific exegetical debates in important ways, and taken as a whole they offer an excellent showcase of contemporary ideas on how to read the Tractatus and its relevance to contemporary thought.
