Tractatus Logico-Philosophicus may be the most important book of philosophy written during the twentieth century. Wittgenstein's writing style is clear, succinct, and accessible. Bertrand Russell claimed that "I cannot see any point on which it is wrong. But to have constructed a theory of logic which is not at any point obviously wrong is to have achieved a work of extraordinary difficulty and importance." Required ready for anyone interested in philosophy.

In the last years of his life, from 1949 to 1951, Wittgenstein's writings focused upon knowledge and certainty (collected together in On Certainty), upon colour concepts (in Remarks on Colour) and upon the relation between the "inner" and "outer," that is, between so-called mental states and bodily behavior. His writings on this third theme, now available in paperback, are gathered here for the first time. Wittgenstein's last weeks were a period of high creativity during which his thoughts were on a level with the best he ever produced. His variation on the classic philosophical theme of the...

Published originally in 1921 this book is considered one of the most important philosophical works of the 20th century. This discussion on philosophical thought can be summed up in this quote from the beginning of the book. "what can be said at all can be said clearly, and what we cannot talk about we must pass over in silence."

"These two volumes must be welcomed in particular for the illumination they shed ... on Wittgenstein's already published discussions ... the characteristic deluge of examples, analogies, questions and challanges is as ever, maddening, provoking and thought-provoking, and with the earlier-published works they constitute not just the most detailed but also the best treatment of these profoundly important issues."

Wittgenstein wrote the Philosophical Grammar during the years 1931 to 1934 - the period just before he began to dictate the Blue Book. Although it is close to the Investigations in some points, and to the Phiosophische Bemerkungen at others, the Philosophical Grammar is an independent work which covers new ground. It is Wittgenstein's fullest treatment of logic and mathematics in their connection with his later understanding of 'proposition', 'sign', and 'system'. He also discusses inference and generality - critisizing views of Frege and Russell as well as earlier views of his own - and the...

This is a completely revised edition of Culture and Value, a collection of Wittgenstein's most accessible commentary on the nature of art, religion, culture and the nature of philosophical activity.

Although the final remarks in this volume were written less than a fortnight before Wittgenstein's death, the work as a whole has all the forcefulness, originality and richness that characterise his greatest works. The remarks in this volume do not merely repeat points made elsewhere, nor do they merely supplement works already published. The volume incorporates genuinely new material that does a great deal to reveal both the subtlety of Wittgenstein's thoughts on subjectivity and the logic of psychological concepts, and the workings of his philosophical method.

Man konnte den ganzen Sinn des Buches etwa in die Worte fassen: was sich berhaupt sagen lt, lt sich klar sagen; und wovon man nicht reden kann, darber mu man schweigen. Das Buch will also dem Denken eine Grenze ziehen, oder vielmehr - nicht dem Denken, sondern dem Ausdruck der Gedanken: denn um dem Denken eine Grenze zu ziehen, mten wir beide Seiten dieser Grenze denken knnen (wir mten also denken knnen, was sich nicht denken lsst. Wittgenstein untersucht die Mglichkeiten des Denkens an den Mglichkeiten der Sprache.

Ludwig Wittgenstein (1889 - 1951) schrieb zwei Hauptwerke, frh die strenge Logisch-philosophische Abhandlung (BS 1322), spt die offeneren, lebendig in immer neuen Anlufen vorgetragenen Philosophischen Untersuchungen, mit denen der Begriff des Sprachspiels in die Welt gekommen ist: Man kann fr eine groe Klasse von Fllen der Bentzung des Wortes Bedeutung - wenn auch nicht fr alle Flle seiner Bentzung - dieses Wort so erklren: Die Bedeutung eines Wortes ist sein Gebrauch in der Sprache.
