" The world is everything that is the case ," wrote Ludwig Wittgenstein in his influential Tractatus Logico-Philosophicus, first published in 1922.

But in his later years, Wittgenstein wrote works which are often interpreted as conflicting with his positions in the Tractatus, and indeed the later Wittgenstein is mainly seen as the leading critic of the early Wittgenstein.

Maurice Ravel wrote his Piano Concerto for the Left Hand, which became more famous than any of the other compositions that Wittgenstein inspired.

Indeed, Wittgenstein wrote in Tractatus Logico Philosophicus that some of the propositions contained in his own book should be regarded as nonsense.

He wrote books about Ludwig Wittgenstein and Karl Popper ( translated into Spanish and Slovene ) and studied the history of Christianity in the Near East and in India ( Nestorian and the western-Syrian " monophysite " church ).

Ludwig Wittgenstein wrote that " if a lion could speak, we would not be able to understand him ".

Late in life, James Joyce wrote to his daughter that it is " the greatest story that the literature of the world knows "; Ludwig Wittgenstein was another well-known admirer.

Although the historical significance of Tractatus is for its influence on the philosophers of logical empiricism, by providing them with a framework for a philosophy of science, and hence engineering, Wittgenstein actually wrote it as a work on ethics.

Wittgenstein wanted to emigrate to Russia, first in the twenties, as he wrote in a letter to Paul Engelmann, and again in the thirties, either to work as a labourer or as a philosophy lecturer.

John Maynard Keynes wrote his dissertation on non-demonstrative reasoning, and influenced the thinking of Ludwig Wittgenstein on this subject.

Wittgenstein stated this in his lectures on aesthetics and language games.

Defining it requires a description of the entire phenomenon, as Wittgenstein argued in his lectures on aesthetics.

Dummett's writings on anti-realism also draw heavily on the later writings of Wittgenstein concerning meaning and rule following.

Logical empiricism ( aka logical positivism or neopositivism ) was an early 20th century attempt to synthesize the essential ideas of British empiricism ( e. g. a strong emphasis on sensory experience as the basis for knowledge ) with certain insights from mathematical logic that had been developed by Gottlob Frege and Ludwig Wittgenstein.

Although Hayek only met Wittgenstein on a few occasions, Hayek said that Wittgenstein's philosophy and methods of analysis had a profound influence on his own life and thought.

After Wittgenstein's death, Hayek had intended to write a biography of Wittgenstein and worked on collecting family materials, and he later assisted biographers of Wittgenstein.

In addition to Moore's own work on the paradox, the puzzle also inspired a great deal of work by Ludwig Wittgenstein, who described the paradox as the most impressive philosophical insight that Moore had ever introduced.

Karl Wittgenstein ( 1847 – 1913 ) became an industrial tycoon, and by the late 1880s was one of the richest men in Europe, with an effective monopoly on Austria's steel cartel.

The main influences on the early logical positivists were the positivist Ernst Mach, Gottlob Frege, Bertrand Russell and the young Ludwig Wittgenstein.

" However, In proposing the thought experiment involving the fictional character, Robinson Crusoe, a captain shipwrecked on a desolate island with no other inhabitant, Wittgenstein shows that language is not in all cases a social phenomenon ( although, they are for most case ); instead the criterion for a language is grounded in a set of interrelated normative activities: teaching, explanations, techniques and criteria of correctness.

Wittgenstein presents several perspectives on the topic.

The discussion of private languages was revitalized in 1982 with the publication of Saul Kripke's book Wittgenstein on Rules and Private Language.

From his remarks on the importance of public, observable behavior ( as opposed to private experiences ), it may seem that Wittgenstein is simply a behaviorist — one who thinks that mental states are nothing over and above certain behavior.

The Tractatus, as Bertrand Russell saw it ( though it should be noted that Wittgenstein took strong exception to Russell's reading ), had been an attempt to set out a logically perfect language, building on Russell's own work.

Norman Malcolm credits Piero Sraffa with providing Wittgenstein with the conceptual break that founded the Philosophical Investigations, by means of a rude gesture on Sraffa's part:

Wittgenstein in his Lectures on the Foundations of Mathematics, Cambridge 1939 criticised Principia on various grounds, such as:

Although Wittgenstein largely disregarded Aristotle ( Ray Monk's biography suggests that he never read Aristotle at all ) it seems that they shared some anti-Platonist views on the universal / particular issue regarding primary substances.

Moreover, there has been extensive commentary on the relationship between the respective treatises of Wittgenstein ( Tractatus ) and Aquinas ( Summa Theologica ).

First published in 1982, Kripke's Wittgenstein on Rules and Private Language contends that the central argument of Wittgenstein's Philosophical Investigations centers on a devastating rule-following paradox that undermines the possibility of our ever following rules in our use of language.

Ludwig Adolph Peter, Prince Wittgenstein ( Pyotr Khristianovich Vitgenshtein ) ( ) ( 17 January ( 6 January ) 1769, Pereiaslav – 11 June 1843, Lemberg, Austrian Empire ) was a Russian Field Marshal distinguished for his services in the Napoleonic wars.

:" There is another course, recommended by Wittgenstein † († Tractatus Logico-Philosophicus, * 5. 54ff ) for philosophical reasons.

Wittgenstein shows that this operator can cope with the whole of predicate logic with identity, defining the quantifiers at 5. 52, and showing how identity would then be handled at 5. 53-5. 532.

Paul Wittgenstein ( November 5, 1887March 3, 1961 ) was an Austrian-born concert pianist who became known for commissioning new piano concerti for the left hand alone, following the amputation of his right arm during the First World War.

Although Wittgenstein did not use the expression Logical Atomism, the book espouses most of Russell's logical atomism except for Russell's Theory of Knowledge ( T 5. 4 and 5. 5541 ).

Other shortlisted figures were David Hume ( 12. 7 %), Ludwig Wittgenstein ( 6. 8 %), Friedrich Nietzsche ( 6. 5 %), Plato ( 5. 6 %), Immanuel Kant ( 5. 6 %), Thomas Aquinas ( 4. 8 %), Socrates ( 4. 8 %), Aristotle ( 4. 5 %) and Karl Popper ( 4. 2 %).

In the Tractatus Logico-Philosophicus of Ludwig Wittgenstein, Proposition 6. 5 seeks to ground his philosophy of action ( Proposition 7: " Whereof one cannot speak, thereof one must be silent ").

Proposition 6. 5 ( and its consequence ) can not be understood until one realizes that Wittgenstein was a son of a family at the apex of Viennese culture, the capital of an empire ( now vanished ).
