151 Facts About Ludwig Wittgenstein

Ludwig Josef Johann Wittgenstein was an Austrian philosopher who worked primarily in logic, the philosophy of mathematics, the philosophy of mind, and the philosophy of language.

Ludwig Wittgenstein is considered by some to be the greatest philosopher of the 20th century.

From 1929 to 1947, Wittgenstein taught at the University of Cambridge.

Ludwig Wittgenstein's philosophy is often divided into an early period, exemplified by the Tractatus, and a later period, articulated primarily in the Philosophical Investigations.

The "early Ludwig Wittgenstein" was concerned with the logical relationship between propositions and the world, and he believed that by providing an account of the logic underlying this relationship, he had solved all philosophical problems.

The "later Ludwig Wittgenstein" rejected many of the assumptions of the Tractatus, arguing that the meaning of words is best understood as their use within a given language game.

Ludwig Wittgenstein later expressed remorse for these incidents, and spent the remainder of his life lecturing and attempting to prepare a second manuscript for publication, which was published posthumously as the hugely influential Philosophical Investigations.

Ludwig Wittgenstein was an aunt of the Nobel Prize laureate Friedrich Hayek on her maternal side.

Ludwig Wittgenstein, who valued precision and discipline, never considered contemporary music acceptable.

Ludwig Wittgenstein learnt to play the clarinet in his 30s.

Ludwig Wittgenstein had asked the pianist to play Thomas Koschat's "Verlassen, verlassen, verlassen bin ich", before mixing himself a drink of milk and potassium cyanide.

Ludwig Wittgenstein was baptized as an infant by a Catholic priest and received formal instruction in Catholic doctrine as a child, as was common at the time.

Ludwig Wittgenstein nevertheless believed in the importance of the idea of confession.

Ludwig Wittgenstein discussed it with Gretl, his other sister, who directed him to Schopenhauer's The World as Will and Representation.

In later years, Ludwig Wittgenstein was highly dismissive of Schopenhauer, describing him as an ultimately "shallow" thinker:.

In 1912, Ludwig Wittgenstein wrote to Russell saying that Mozart and Beethoven were the actual sons of God.

Ludwig Wittgenstein's religious belief emerged during his service for the Austrian army in World War I, and he was a devoted reader of Dostoevsky's and Tolstoy's religious writings.

Ludwig Wittgenstein viewed his wartime experiences as a trial in which he strove to conform to the will of God, and in a journal entry from 29 April 1915, he writes:.

Around this time, Ludwig Wittgenstein wrote that "Christianity is indeed the only sure way to happiness", but he rejected the idea that religious belief was merely thinking that a certain doctrine was true.

From this time on, Ludwig Wittgenstein viewed religious faith as a way of living and opposed rational argumentation or proofs for God.

Many years later, as a professor at the University of Cambridge, Ludwig Wittgenstein distributed copies of Weininger's book to his bemused academic colleagues.

Ludwig Wittgenstein said that Weininger's arguments were wrong, but that it was the way they were wrong that was interesting.

Ludwig Wittgenstein and Hitler were born just six days apart, though Hitler had to re-sit his mathematics exam before being allowed into a higher class, while Ludwig Wittgenstein was moved forward by one, so they ended up two grades apart at the Realschule.

Ludwig Wittgenstein conducted research into the behavior of kites in the upper atmosphere, experimenting at a meteorological observation site near Glossop in Derbyshire.

At Glossop, Ludwig Wittgenstein worked under Professor of Physics Sir Arthur Schuster.

Ludwig Wittgenstein worked on the design of a propeller with small jet engines on the end of its blades, something he patented in 1911, and which earned him a research studentship from the university in the autumn of 1908.

Ludwig Wittgenstein's design required air and gas to be forced along the propeller arms to combustion chambers on the end of each blade, where it was then compressed by the centrifugal force exerted by the revolving arms and ignited.

Work on the jet-powered propeller proved frustrating for Ludwig Wittgenstein, who had very little experience working with machinery.

Ludwig Wittgenstein was not only attending Russell's lectures, but dominating them.

Ludwig Wittgenstein started following him after lectures back to his rooms to discuss more philosophy, until it was time for the evening meal in Hall.

Ludwig Wittgenstein maintained, for example, at one time that all existential propositions are meaningless.

Ludwig Wittgenstein later told David Pinsent that Russell's encouragement had proven his salvation, and had ended nine years of loneliness and suffering, during which he had continually thought of suicide.

The role-reversal between Bertrand Russell and Ludwig Wittgenstein was such that Russell wrote in 1916, after Ludwig Wittgenstein had criticized Russell's own work:.

Ludwig Wittgenstein's [Wittgenstein's] criticism, tho' I don't think you realized it at the time, was an event of first-rate importance in my life, and affected everything I have done since.

Ludwig Wittgenstein dominated the society and for a time would stop attending in the early 1930s after complaints that he gave no one else a chance to speak.

Accounts vary as to what happened next, but Ludwig Wittgenstein apparently started waving a hot poker, demanding that Popper give him an example of a moral rule.

Popper maintained that Ludwig Wittgenstein "stormed out", but it had become accepted practice for him to leave early.

The economist John Maynard Keynes invited him to join the Cambridge Apostles, an elite secret society formed in 1820, which both Bertrand Russell and G E Moore had joined as students, but Wittgenstein did not greatly enjoy it and attended only infrequently.

Ludwig Wittgenstein was admitted in 1912 but resigned almost immediately because he could not tolerate the style of discussion.

Nevertheless, the Cambridge Apostles allowed Ludwig Wittgenstein to participate in meetings again in the 1920s when he had returned to Cambridge.

Reportedly, Ludwig Wittgenstein had trouble tolerating the discussions in the Cambridge Moral Sciences Club.

Ludwig Wittgenstein was quite vocal about his depression in his years at Cambridge, and before he went to war; on many an occasion, he told Russell of his woes.

Ludwig Wittgenstein made numerous remarks to Russell about logic driving him mad.

Ludwig Wittgenstein stated to Russell that he "felt the curse of those who have half a talent".

Ludwig Wittgenstein later expresses this same worry, and tells of being in mediocre spirits due to his lack of progress in his logical work.

Ludwig Wittgenstein later claimed that, as a teenager in Vienna, he had had an affair with a woman.

Additionally, in the 1920s Ludwig Wittgenstein fell in love with a young Swiss woman, Marguerite Respinger, sculpting a bust modelled on her and seriously considering marriage, albeit on condition that they would not have children; she decided that he was not right for her.

The men worked together on experiments in the psychology laboratory about the role of rhythm in the appreciation of music, and Ludwig Wittgenstein delivered a paper on the subject to the British Psychological Association in Cambridge in 1912.

The immense progress on logic during their stay led Ludwig Wittgenstein to express to Pinsent his notion of leaving Cambridge and returning to Norway to continue his work on logic.

Pinsent writes of Ludwig Wittgenstein being "absolutely sulky and snappish" at times, as well.

Ludwig Wittgenstein wrote in May 1912 that Wittgenstein had just begun to study the history of philosophy:.

Ludwig Wittgenstein donated some of his money, at first anonymously, to Austrian artists and writers, including Rainer Maria Rilke and Georg Trakl.

Trakl requested to meet his benefactor but in 1914 when Ludwig Wittgenstein went to visit, Trakl had killed himself.

Ludwig Wittgenstein came to feel that he could not get to the heart of his most fundamental questions while surrounded by other academics, and so in 1913 he retreated to the village of Skjolden in Norway, where he rented the second floor of a house for the winter.

Ludwig Wittgenstein later saw this as one of the most productive periods of his life, writing Logik, the predecessor of much of the Tractatus.

Ludwig Wittgenstein adored the "quiet seriousness" of the landscape but even Skjolden became too busy for him.

Ludwig Wittgenstein soon designed a small wooden house which was erected on a remote rock overlooking the Eidsvatnet Lake just outside the village.

Ludwig Wittgenstein discovered Leo Tolstoy's 1896 The Gospel in Brief at a bookshop in Tarnow, and carried it everywhere, recommending it to anyone in distress, to the point where he became known to his fellow soldiers as "the man with the gospels".

The extent to which The Gospel in Brief influenced Ludwig Wittgenstein can be seen in the Tractatus, in the unique way both books number their sentences.

In 1916 Ludwig Wittgenstein read Dostoevsky's The Brothers Karamazov so often that he knew whole passages of it by heart, particularly the speeches of the elder Zosima, who represented for him a powerful Christian ideal, a holy man "who could see directly into the souls of other people".

Piribauer had been sent for by the children when they saw Haidbauer collapse; Ludwig Wittgenstein had previously pulled Piribauer's daughter, Hermine, so hard by the ears that her ears had bled.

Piribauer tried to have Ludwig Wittgenstein arrested, but the village's police station was empty, and when he tried again the next day he was told Ludwig Wittgenstein had disappeared.

On 28 April 1926, Ludwig Wittgenstein handed in his resignation to Wilhelm Kundt, a local school inspector, who tried to persuade him to stay; however, Ludwig Wittgenstein was adamant that his days as a schoolteacher were over.

Ten years later, in 1936, as part of a series of "confessions" he engaged in that year, Ludwig Wittgenstein appeared without warning at the village saying he wanted to confess personally and ask for pardon from the children he had hit.

Ludwig Wittgenstein visited at least four of the children, including Hermine Piribauer, who apparently replied only with a "Ja, ja," though other former students were more hospitable.

Ludwig Wittgenstein had developed a friendship with Keith Kirk, a working-class teenage friend of Francis Skinner, the mathematics undergraduate he had had a relationship with until Skinner's death in 1941 from polio.

Kirk and Ludwig Wittgenstein struck up a friendship, with Ludwig Wittgenstein giving him lessons in physics to help him pass a City and Guilds exam.

Ludwig Wittgenstein had only maintained contact with Fouracre, from Guy's hospital, who had joined the army in 1943 after his marriage, only returning in 1947.

Ludwig Wittgenstein asks the reader to think of language as a multiplicity of language games within which parts of language develop and function.

Ludwig Wittgenstein describes this metaphysical environment as like being on frictionless ice: where the conditions are apparently perfect for a philosophically and logically perfect language, all philosophical problems can be solved without the muddying effects of everyday contexts; but where, precisely because of the lack of friction, language can in fact do no work at all.
