One of the greatest philosophical works of all time, in a new translation for the twenty-first century A Penguin Classic Widely regarded as one of the most influential philosophical works of the twentieth century, Ludwig Wittgenstein's T ractatus Logico-Philosophicus is a succinct yet wide-ranging exploration of language and logic, science and mysticism, which has inspired generations of thinkers, artists and poets. In a series of short, bold statements, Wittgenstein seeks to define the limits of language, its relation to logic, its power and its inherent failings. Originally published in the early 1920s, it is the only book-length work the renowned philosopher published in his lifetime. In this thrilling new translation, Alexander Booth displays an extraordinary sensitivity to the subtle influence on Wittgenstein's gem-like prose--at once specialist and, often, remarkably plain-spoken--considering his background in mechanical engineering, while highlighting the underlying poetry of this seminal text. Penguin Classics is the leading publisher of classic literature in the English-speaking world, representing a global bookshelf of the best works throughout history and across genres and disciplines. Readers trust the series to provide authoritative texts enhanced by introductions and notes by distinguished scholars and contemporary authors, as well as up-to-date translations by award-winning translators.
