In 1933, Wittgenstein set out to dictate a collection of his recent writings to a typist in the form of a book. Even as he was dictating he began revising the text extensively, so that the surviving typewritten manuscript contains numerous corrections, additions, deletions, alternative words and phrasings, suggestions for moves within the text, and marginal comments in both handwritten and typed form.Long awaited by the scholarly community, Wittgenstein 's so-called Big Typescript (von Wright Catalog no. TS 213) is presented here for the first time in an en-face German -English scholars ' edition, complete with clear indications to help the reader identify the various levels of Wittgenstein 's editing.This text provided a rich source of material for Wittgenstein 's subsequent writings, and therefore serves as a key to understanding much of his later philosophy.
Ludwig Josef Johann Wittgenstein (Ph.D., Trinity College, Cambridge University, 1929) was an Austrian-British philosopher who worked primarily in logic, the philosophy of mathematics, the philosophy of mind, and the philosophy of language.
Described by Bertrand Russell as "the most perfect example I have ever known of genius as traditionally conceived, passionate, profound, intense, and dominating", he helped inspire two of the twentieth century's principal philosophical movements: the Vienna Circle and Oxford ordinary language philosophy. According to an end of the century poll, professional philosophers in Canada and the U.S. rank both his Tractatus Logico-Philosophicus and Philosophical Investigations among the top five most important books in twentieth-century philosophy, the latter standing out as "...the one crossover masterpiece in twentieth-century philosophy, appealing across diverse specializations and philosophical orientations". Wittgenstein's influence has been felt in nearly every field of the humanities and social sciences, yet there are widely diverging interpretations of his thought.
