Family temperament and the brothers' suicides

Ray Monk writes that Karl's aim was to turn his sons into captains of industry; they were not sent to school lest they acquire bad habits, but were educated at home to prepare them for work in Karl's industrial empire. Three of the five brothers would later commit suicide. Psychiatrist Michael Fitzgerald argues that Karl was a harsh perfectionist who lacked empathy, and that Wittgenstein's mother was anxious and insecure, unable to stand up to her husband. Johannes Brahms said of the family, whom he visited regularly:
They seemed to act towards one another as if they were at court.
The family appeared to have a strong streak of depression running through it.

The second eldest brother, Kurt, an officer and company director, shot himself on 27 October 1918 just before the end of World War I, when the Austrian troops he was commanding refused to obey his orders and deserted ''en masse''. According to Gottlieb, Hermine had said Kurt seemed to carry "the germ of disgust for life within himself". Later, Ludwig wrote:

1903–1906: Realschule in Linz


Realschule in Linz

Wittgenstein was taught by private tutors at home until he was 14 years old. Subsequently, for three years, he attended a school. After the deaths of Hans and Rudi, Karl relented, and allowed Paul and Ludwig to be sent to school. Waugh writes that it was too late for Wittgenstein to pass his exams for the more academic ''Gymnasium'' in Wiener Neustadt; having had no formal schooling, he failed his entrance exam and only barely managed after extra tutoring to pass the exam for the more technically oriented k.u.k. ''

In his leaving certificate, he received a top mark (5) in religious studies; a 2 for conduct and English, 3 for French, geography, history, mathematics and physics, and 4 for German, chemistry, geometry and freehand drawing. He had particular difficulty with spelling and failed his written German exam because of it. He wrote in 1931:

in general, for which he always professed a sincere and devoted sympathy, would change over time, much like his philosophical ideas. In 1912, Wittgenstein wrote to Russell saying that Mozart and Beethoven were the actual sons of God. However, Wittgenstein resisted formal religion, saying it was hard for him to "bend the knee", though his grandfather's beliefs continued to influence Wittgenstein – as he said,
I cannot help seeing every problem from a religious point of view.

. 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. He viewed his wartime experiences as a trial in which he strived to conform to the will of God, and in a journal entry from 29 April 1915, he writes:
Perhaps the nearness of death will bring me the light of life. May God enlighten me. I am a worm, but through God I become a man. God be with me. Amen.
Around this time, 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, Wittgenstein viewed religious faith as a way of living and opposed rational argumentation or proofs for God. With age, a deepening personal spirituality led to several elucidations and clarifications, as he untangled language problems in religionattacking, for example, the temptation to think of God's existence as a matter of scientific evidence. In 1947, finding it more difficult to work, he wrote:
I have had a letter from an old friend in Austria, a priest. In it he says that he hopes my work will go well, if it should be God's will. Now that is all I want: if it should be God's will.Rush Rhees, "Ludwig Wittgenstein: Personal Recollections"
In ''Culture and Value'', Wittgenstein writes:
Is what I am doing y work in philosophyreally worth the effort? Yes, but only if a light shines on it from above.
His close friend Norman Malcolm would write:
Wittgenstein's mature life was strongly marked by religious thought and feeling. I am inclined to think that he was more deeply religious than are many people who correctly regard themselves as religious believers.
Toward the end, Wittgenstein wrote:
Bach wrote on the title page of his '' Orgelbüchlein'', 'To the glory of the most high God, and that my neighbour may be benefited thereby.' That is what I would have liked to say about my work.

, and that Jews tend to embody the Platonic femininity. Whereas men are basically rational, women operate only at the level of their emotions and sexual organs. Jews, Weininger argued, are similar, saturated with femininity, with no sense of right and wrong, and no soul. Weininger argues that man must choose between his masculine and feminine sides, consciousness and unconsciousness, Platonic love and sexuality. Love and sexual desire stand in contradiction, and love between a woman and a man is therefore doomed to misery or immorality. The only life worth living is the spiritual one – to live as a woman or a Jew means one has no right to live at all; the choice is genius or death. Weininger committed suicide, shooting himself in 1903, shortly after publishing the book. Wittgenstein, then 14, attended Weininger's funeral. Many years later, as a professor at the

, Wittgenstein distributed copies of Weininger's book to his bemused academic colleagues. He said that Weininger's arguments were wrong, but that it was the way they were wrong that was interesting. In a letter dated 23 August 1931, Wittgenstein wrote the following to G. E. Moore:
Dear Moore,

Thanks for your letter. I can quite imagine that you don't admire Weininger very much, what with that beastly translation and the fact that W. must feel very foreign to you. It is true that he is fantastic but he is great and fantastic. It isn't necessary or rather not possible to agree with him but the greatness lies in that with which we disagree. It is his enormous mistake which is great. I.e. roughly speaking if you just add a "∼" to the whole book it says an important truth.
In an unusual move, Wittgenstein took out a copy of Weininger's work on 1 June 1931 from the Special Order Books in the university library. He met Moore on 2 June, when he probably gave this copy to Moore.


Jewish background and Hitler

There is much debate about the extent to which Wittgenstein and his siblings, who were of 3/4 Jewish descent, saw themselves as Jews. The issue has arisen in particular regarding Wittgenstein's schooldays, because

argues that it is "overwhelmingly probable" that the boys met each other and that Hitler would have disliked Wittgenstein, a "stammering, precocious, precious, aristocratic upstart ..." Other commentators have dismissed as irresponsible and uninformed any suggestion that Wittgenstein's wealth and unusual personality may have fed Hitler's antisemitism, in part because there is no indication that Hitler would have seen Wittgenstein as Jewish. 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 Wittgenstein was moved forward by one, so they ended up two grades apart at the ''Realschule''. Monk estimates that they were both at the school during the 1904–1905 school year, but says there is no evidence they had anything to do with each other. Several commentators have argued that a school photograph of Hitler may show Wittgenstein in the lower left corner, In his own writings Wittgenstein frequently referred to himself as Jewish, at times as part of an apparent self-flagellation. For example, while berating himself for being a "reproductive" as opposed to "productive" thinker, he attributed this to his own Jewish sense of identity, writing:
The saint is the only Jewish genius. Even the greatest Jewish thinker is no more than talented. (Myself for instance).

. He also 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. At the time, contemporary propeller designs were not advanced enough to actually put Wittgenstein's ideas into practice, and it would be years before a blade design that could support Wittgenstein's innovative design was created. 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. Propellers of the time were typically wood, whereas modern blades are made from pressed steel laminates as separate halves, which are then welded together. This gives the blade a hollow interior, and therefore creates an ideal pathway for the air and gas. Work on the jet-powered propeller proved frustrating for Wittgenstein, who had very little experience working with machinery. Jim Bamber, a British engineer who was his friend and classmate at the time, reported that
when things went wrong, which often occurred, he would throw his arms around, stomp about, and swear volubly in German.
According to William Eccles, another friend from that period, Wittgenstein then turned to more theoretical work, focusing on the design of the propeller – a problem that required relatively sophisticated mathematics. It was at this time that he became interested in the

He was soon not only attending Russell's lectures, but dominating them. The lectures were poorly attended and Russell often found himself lecturing only to C. D. Broad, E. H. Neville, and H.T.J. Norton. Wittgenstein started following him after lectures back to his rooms to discuss more philosophy, until it was time for the evening meal in

: "My German friend threatens to be an infliction." Russell soon came to believe that Wittgenstein was a genius, especially after he had examined Wittgenstein's written work. He wrote in November 1911 that he had at first thought Wittgenstein might be a crank, but soon decided he was a genius:
Some of his early views made the decision difficult. He maintained, for example, at one time that all existential propositions are meaningless. This was in a lecture room, and I invited him to consider the proposition: 'There is no hippopotamus in this room at present.' When he refused to believe this, I looked under all the desks without finding one; but he remained unconvinced.
Three months after Wittgenstein's arrival Russell told Morrell:
I love him & feel he will solve the problems I am too old to solve ... He is ''the'' young man one hopes for.
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. In encouraging him to pursue philosophy and in justifying his inclination to abandon engineering, Russell had, quite literally, saved Wittgenstein's life. The role-reversal between Bertrand Russell and Wittgenstein was soon such that Russell wrote in 1916, after Wittgenstein had criticized Russell's own work:
His ittgenstein'scriticism, 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. I saw that he was right, and I saw that I could not hope ever again to do fundamental work in philosophy.


Cambridge Moral Sciences Club and Apostles

In 1912 Wittgenstein joined the Cambridge Moral Sciences Club, an influential discussion group for philosophy dons and students, delivering his first paper there on 29 November that year, a four-minute talk defining philosophy as
all those primitive propositions which are assumed as true without proof by the various sciences.
He 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. The club became infamous within popular philosophy because of a meeting on 25 October 1946 at

Popper's paper was "Are there philosophical problems?", in which he struck up a position against Wittgenstein's, contending that problems in philosophy are real, not just linguistic puzzles as Wittgenstein argued. Accounts vary as to what happened next, but Wittgenstein apparently started waving a hot poker, demanding that Popper give him an example of a moral rule. Popper offered one – "Not to threaten visiting speakers with pokers" – at which point Russell told Wittgenstein he had misunderstood and Wittgenstein left. Popper maintained that Wittgenstein "stormed out", but it had become accepted practice for him to leave early (because of his aforementioned ability to dominate discussion). It was the only time the philosophers, three of the most eminent in the world, were ever in the same room together. The minutes record that the meeting was

He was admitted in 1912 but resigned almost immediately because he could not tolerate the style of discussion. Nevertheless, the Cambridge Apostles allowed Wittgenstein to participate in meetings again in the 1920s when he had returned to

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


Frustrations at Cambridge

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. His mental anguish seemed to stem from two sources: his work, and his personal life. Wittgenstein made numerous remarks to Russell about logic driving him mad. Wittgenstein also stated to Russell that he "felt the curse of those who have half a talent". He later expresses this same worry, and tells of being in mediocre spirits due to his lack of progress in his logical work. Monk writes that Wittgenstein lived and breathed logic, and a temporary lack of inspiration plunged him into despair. Wittgenstein tells of his work in logic affecting his mental status in a very extreme way. However, he also tells Russell another story. Around Christmas, in 1913, he writes:
how can I be a logician before I'm a human being? For the most important thing is coming to terms with myself!
He also tells Russell on an occasion in Russell's rooms that he was worried about logic and his sins; also, once upon arrival to Russell's rooms one night Wittgenstein announced to Russell that he would kill himself once he left. Of things Wittgenstein personally told Russell, Ludwig's temperament was also recorded in the diary of . Pinsent writes
I have to be frightfully careful and tolerant when he gets these sulky fits
and
I am afraid he is in an even more sensitive neurotic state just now than usual
when talking about Wittgenstein's emotional fluctuations.


Sexual orientation and relationship with David Pinsent

Wittgenstein had romantic relations with both men and women. He is generally believed to have fallen in love with at least three men, and had a relationship with the latter two: in 1912,

in 1930, and Ben Richards in the late 1940s. He later revealed that, as a teenager in Vienna, he had had an affair with a woman. Additionally, in the 1920s 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. Wittgenstein's relationship with David Pinsent (1891–1918) occurred during an intellectually formative period, and is well documented. Bertrand Russell introduced Wittgenstein to Pinsent in the summer of 1912. Pinsent was a mathematics undergraduate and a relation of

, and Wittgenstein and he soon became very close. The men worked together on experiments in the psychology laboratory about the role of rhythm in the appreciation of music, and Wittgenstein delivered a paper on the subject to the British Psychological Association in Cambridge in 1912. They also travelled together, including to Iceland in September 1912the expenses paid by Wittgenstein, including

, the hiring of a private train, and new clothes and spending money for Pinsent. In addition to Iceland, Wittgenstein and Pinsent traveled to Norway in 1913. In determining their destination, Wittgenstein and Pinsent visited a tourist office in search of a location that would fulfill the following criteria: a small village located on a fjord, a location away from tourists, and a peaceful destination to allow them to study logic and law. Choosing Øystese, Wittgenstein and Pinsent arrived in the small village on 4 September 1913. During a vacation lasting almost three weeks, Wittgenstein was able to work vigorously on his studies. The immense progress on logic during their stay led Wittgenstein to express to Pinsent his notion of leaving Cambridge and returning to Norway to continue his work on logic. Pinsent's diaries provide valuable insights into Wittgenstein's personality: sensitive, nervous, and attuned to the tiniest slight or change in mood from Pinsent. Pinsent also writes of Wittgenstein being "absolutely sulky and snappish" at times, as well. In his diaries Pinsent wrote about shopping for furniture with Wittgenstein in Cambridge when the latter was given rooms in Trinity. Most of what they found in the stores was not minimalist enough for Wittgenstein's aesthetics:
I went and helped him interview a lot of furniture at various shops ... It was rather amusing: He is terribly fastidious and we led the shopman a frightful dance, Vittgenstein ejaculating ''"No – Beastly!"'' to 90 percent of what he shewed rchaic spellingus!
He wrote in May 1912 that Wittgenstein had just begun to study the history of philosophy:
He expresses the most naive surprise that all the philosophers he once worshipped in ignorance are after all stupid and dishonest and make disgusting mistakes!
The last time they saw each other was on 8 October 1913 at Lordswood House in Birmingham, then residence of the Pinsent family:
I got up at 6:15 to see Ludwig off. He had to go very earlyback to Cambridgeas he has lots to do there. I saw him off from the house in a taxi at 7:00to catch a 7:30  train from New Street Station. It was sad parting from him.
Wittgenstein left to live in Norway.


1913–1920: World War I and the ''Tractatus''


Work on ''Logik''

Karl Wittgenstein died on 20 January 1913, and after receiving his inheritance Wittgenstein became one of the wealthiest men in Europe. He donated some of his money, at first anonymously, to Austrian artists and writers, including

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

. He adored the "quiet seriousness" of the landscape but even Skjolden became too busy for him. He soon designed a small wooden house which was erected on a remote rock overlooking the Eidsvatnet Lake just outside the village. The place was called "Østerrike" (Austria) by locals. He lived there during various periods until the 1930s; substantial parts of his works were written here. (The house was broken up in 1958 to be rebuilt in the village. A local foundation collected donations and bought it in 2014; it was dismantled again and re-erected at its original location; the inauguration took place on 20 June 2019 under international attendance.) It was during this time that Wittgenstein began addressing what he considered to be a central issue in ''Notes on Logic'', a general decision procedure for determining the truth value of logical propositions which would stem from a single primitive proposition. He became convinced during this time that
l the propositions of logic are generalizations of tautologies and all generalizations of tautologies are generalizations of logic. There are no other logical propositions.
Based on this, Wittgenstein argued that propositions of logic express their truth or falsehood in the sign itself, and one need not know anything about the constituent parts of the proposition to determine it true or false. Rather, one simply need identify the statement as a tautology (true), a contradiction (false), or neither. The problem lay in forming a primitive proposition which encompassed this and would act as the basis for all of logic. As he stated in correspondence with Russell in late 1913,
The big question now is, how must a system of signs be constituted in order to make every tautology recognizable as such IN ONE AND THE SAME WAY? This is the fundamental problem of logic!
The importance Wittgenstein placed upon this fundamental problem was so great that he believed if he did not solve it, he had no reason or right to live. Despite this apparent life-or-death importance, Wittgenstein had given up on this primitive proposition by the time of the writing of the ''Tractatus''. The ''Tractatus'' does not offer any general process for identifying propositions as tautologies; in a simpler manner,
Every tautology itself shows that it is a tautology.
This shift to understanding tautologies through mere identification or recognition occurred in 1914 when Moore was called on by Wittgenstein to assist him in dictating his notes. At Wittgenstein's insistence, Moore, who was now a Cambridge don, visited him in Norway in 1914, reluctantly because Wittgenstein exhausted him. David Edmonds and John Eidinow write that Wittgenstein regarded Moore, an internationally known philosopher, as an example of how far someone could get in life with ''"absolutely no intelligence whatever."'' In Norway it was clear that Moore was expected to act as Wittgenstein's secretary, taking down his notes, with Wittgenstein falling into a rage when Moore got something wrong. When he returned to Cambridge, Moore asked the university to consider accepting ''Logik'' as sufficient for a bachelor's degree, but they refused, saying it wasn't formatted properly: no footnotes, no preface. Wittgenstein was furious, writing to Moore in May 1914:
If I am not worth your making an exception for me ''even in some STUPID details'' then I may as well go to Hell directly; and if I ''am'' worth it and you don't do it then – by God – ''you'' might go there.
Moore was apparently distraught; he wrote in his diary that he felt sick and could not get the letter out of his head. The two did not speak again until 1929.

In 1918, he was promoted to lieutenant and sent to the Italian front as part of an artillery regiment. For his part in the final Austrian offensive of June 1918, he was recommended for the Gold Medal for Valour, one of the highest honours in the Austrian army, but was instead awarded the Band of the Military Service Medal with Swordsit being decided that this particular action, although extraordinarily brave, had been insufficiently consequential to merit the highest honour. Throughout the war, he kept notebooks in which he frequently wrote philosophical reflections alongside personal remarks, including his contempt for the character of the other soldiers. His notebooks also attest to his philosophical and spiritual reflections, and it was during this time that he experienced a kind of religious awakening. In his entry from 11 June 1915, Wittgenstein states that

Completion of the ''Tractatus''

In the summer of 1918 Wittgenstein took military leave and went to stay in one of his family's Vienna summer houses, Neuwaldegg. It was there in August 1918 that he completed the ''Tractatus'', which he submitted with the title ''Der Satz'' (German: proposition, sentence, phrase, set, but also "leap") to the publishers Jahoda and Siegel. A series of events around this time left him deeply upset. On 13 August, his uncle Paul died. On 25 October, he learned that Jahoda and Siegel had decided not to publish the ''Tractatus'', and on 27 October, his brother Kurt killed himself, the third of his brothers to commit suicide. It was around this time he received a letter from David Pinsent's mother to say that Pinsent had been killed in a plane crash on 8 May. Wittgenstein was distraught to the point of being suicidal. He was sent back to the Italian front after his leave and, as a result of the defeat of the Austrian army, he was captured by Allied forces on 3 November in

In 1914, it had been providing him with an income of 300,000  Kronen a year, but by 1919 was worth a great deal more, with a sizable portfolio of investments in the

1920–1928: Teaching, the ''Tractatus'', Haus Wittgenstein


Teacher training in Vienna

In September 1919 he enrolled in the ''Lehrerbildungsanstalt'' (teacher training college) in the ''Kundmanngasse'' in Vienna. His sister Hermine said that Wittgenstein working as an elementary teacher was like using a precision instrument to open crates, but the family decided not to interfere.

, more critically, wrote of this period in Wittgenstein's life: ''"the multi-millionaire as a village schoolmaster is surely a piece of perversity."''


Teaching posts in Austria

In the summer of 1920, Wittgenstein worked as a gardener for a monastery. At first he applied, under a false name, for a teaching post at Reichenau, was awarded the job, but he declined it when his identity was discovered. As a teacher, he wished to no longer be recognized as a member of the Wittgenstein family. In response, his brother Paul wrote:
It is out of the question, really completely out of the question, that anybody bearing our name and whose elegant and gentle upbringing can be seen a thousand paces off, would not be identified as a member of our family ... That one can neither simulate nor dissimulate anything including a refined education I need hardly tell you.
In 1920, Wittgenstein was given his first job as a primary school teacher in Trattenbach, under his real name, in a remote village of a few hundred people. His first letters describe it as beautiful, but in October 1921, he wrote to Russell: "I am still at Trattenbach, surrounded, as ever, by odiousness and baseness. I know that human beings on the average are not worth much anywhere, but here they are much more good-for-nothing and irresponsible than elsewhere." He was soon the object of gossip among the villagers, who found him eccentric at best. He did not get on well with the other teachers; when he found his lodgings too noisy, he made a bed for himself in the school kitchen. He was an enthusiastic teacher, offering late-night extra tuition to several of the students, something that did not endear him to the parents, though some of them came to adore him; his sister Hermine occasionally watched him teach and said the students "literally crawled over each other in their desire to be chosen for answers or demonstrations." To the less able, it seems that he became something of a tyrant. The first two hours of each day were devoted to mathematics, hours that Monk writes some of the pupils recalled years later with horror. They reported that he caned the boys and boxed their ears, and also that he pulled the girls' hair; this was not unusual at the time for boys, but for the villagers he went too far in doing it to the girls too; girls were not expected to understand algebra, much less have their ears boxed over it. The violence apart, Monk writes that he quickly became a village legend, shouting "Krautsalat!" ("coleslaw" – i.e. shredded cabbage) when the headmaster played the piano, and "Nonsense!" when a priest was answering children's questions.


Publication of the ''Tractatus''

While Wittgenstein was living in isolation in rural Austria, the ''

's journal ''Annalen der Naturphilosophie'', though Wittgenstein was not happy with the result and called it a pirate edition. Russell had agreed to write an introduction to explain why it was important, because it was otherwise unlikely to have been published: it was difficult if not impossible to understand, and Wittgenstein was unknown in philosophy. In a letter to Russell, Wittgenstein wrote "The main point is the theory of what can be expressed (gesagt) by prop sition – i.e. by language – (and, which comes to the same thing, what can be ''thought'') and what can not be expressed by pro osition, but only shown (gezeigt); which, I believe, is the cardinal problem of philosophy." But Wittgenstein was not happy with Russell's help. He had lost faith in Russell, finding him glib and his philosophy mechanistic, and felt he had fundamentally misunderstood the ''Tractatus''. An English translation was prepared in Cambridge by Frank Ramsey, a mathematics undergraduate at King's commissioned by C. K. Ogden. It was Moore who suggested ''Tractatus Logico-Philosophicus'' for the title, an allusion to

's ''Tractatus Theologico-Politicus.'' Initially there were difficulties in finding a publisher for the English edition too, because Wittgenstein was insisting it appear without Russell's introduction; Cambridge University Press turned it down for that reason. Finally in 1922 an agreement was reached with Wittgenstein that Kegan Paul would print a bilingual edition with Russell's introduction and the Ramsey-Ogden translation. This is the translation that was approved by Wittgenstein, but it is problematic in a number of ways. Wittgenstein's English was poor at the time, and Ramsey was a teenager who had only recently learned German, so philosophers often prefer to use a 1961 translation by

and Brian McGuinness. An aim of the ''Tractatus'' is to reveal the relationship between language and the world: what can be said about it, and what can only be shown. Wittgenstein argues that the logical structure of language provides the limits of meaning. The limits of language, for Wittgenstein, are the limits of philosophy. Much of philosophy involves attempts to say the unsayable: "What we can say at all can be said clearly," he argues. Anything beyond that – religion, ethics, aesthetics, the mystical – cannot be discussed. They are not in themselves nonsensical, but any statement about them must be. He wrote in the preface: "The book will, therefore, draw a limit to thinking, or rather – not to thinking, but to the expression of thoughts; for, in order to draw a limit to thinking we should have to be able to think both sides of this limit (we should therefore have to be able to think what cannot be thought)." The book is 75 pages long – "As to the shortness of the book, I am ''awfully sorry for it'' ... If you were to squeeze me like a lemon you would get nothing more out of me," he told Ogden – and presents seven numbered propositions (1–7), with various sub-levels (1, 1.1, 1.11): # ''Die Welt ist alles, was der Fall ist''. #: The world is everything that is the case. # ''Was der Fall ist, die Tatsache, ist das Bestehen von Sachverhalten''. #: What is the case, the fact, is the existence of

Visit from Frank Ramsey, Puchberg

In September 1922 he moved to a secondary school in a nearby village, Hassbach, but considered the people there just as bad – "These people are not human ''at all'' but loathsome worms," he wrote to a friend – and he left after a month. In November he began work at another primary school, this time in Puchberg in the Schneeberg mountains. There, he told Russell, the villagers were "one-quarter animal and three-quarters human." Frank P. Ramsey visited him on 17 September 1923 to discuss the ''Tractatus''; he had agreed to write a review of it for ''Mind''. He reported in a letter home that Wittgenstein was living frugally in one tiny whitewashed room that only had space for a bed, a washstand, a small table, and one small hard chair. Ramsey shared an evening meal with him of coarse bread, butter, and cocoa. Wittgenstein's school hours were eight to twelve or one, and he had afternoons free. After Ramsey returned to Cambridge a long campaign began among Wittgenstein's friends to persuade him to return to Cambridge and away from what they saw as a hostile environment for him. He was accepting no help even from his family. Ramsey wrote to

Teaching continues, Otterthal; Haidbauer incident

He moved schools again in September 1924, this time to Otterthal, near Trattenbach; the socialist headmaster, Josef Putre, was someone Wittgenstein had become friends with while at Trattenbach. While he was there, he wrote a 42 page pronunciation and spelling dictionary for the children, ''Wörterbuch für Volksschulen'', published in Vienna in 1926 by Hölder-Pichler-Tempsky, the only book of his apart from the ''Tractatus'' that was published in his lifetime. A first edition sold in 2005 for £75,000. In 2020, an English version entitled ''Word Book'' translated by art historian Bettina Funcke and illustrated by artist / publisher Paul Chan was released. An incident occurred in April 1926 and became known as ''Der Vorfall Haidbauer'' (the Haidbauer incident). Josef Haidbauer was an 11 year-old pupil whose father had died and whose mother worked as a local maid. He was a slow learner, and one day Wittgenstein hit him two or three times on the head, causing him to collapse. Wittgenstein carried him to the headmaster's office, then quickly left the school, bumping into a parent, Herr Piribauer, on the way out. Piribauer had been sent for by the children when they saw Haidbauer collapse; Wittgenstein had previously pulled Piribauer's daughter, Hermine, so hard by the ears that her ears had bled. Piribauer said that when he met Wittgenstein in the hall that day:
I called him all the names under the sun. I told him he wasn't a teacher, he was an animal-trainer! And that I was going to fetch the police right away!
Piribauer tried to have Wittgenstein arrested, but the village's police station was empty, and when he tried again the next day he was told Wittgenstein had disappeared. On 28 April 1926, Wittgenstein handed in his resignation to Wilhelm Kundt, a local school inspector, who tried to persuade him to stay; however, Wittgenstein was adamant that his days as a schoolteacher were over. Proceedings were initiated in May, and the judge ordered a psychiatric report; in August 1926 a letter to Wittgenstein from a friend, Ludwig Hänsel, indicates that hearings were ongoing, but nothing is known about the case after that. Alexander Waugh writes that Wittgenstein's family and their money may have had a hand in covering things up. Waugh writes that Haidbauer died shortly afterwards of haemophilia; Monk says he died when he was 14 of

. Ten years later, in 1936, as part of a series of "confessions" he engaged in that year, Wittgenstein appeared without warning at the village saying he wanted to confess personally and ask for pardon from the children he had hit. He 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. Monk writes that the purpose of these confessions was not
to hurt his pride, as a form of punishment; it was to dismantle it – to remove a barrier, as it were, that stood in the way of honest and decent thought.
Of the apologies, Wittgenstein wrote,
This brought me into more settled waters... and to greater seriousness.


The Vienna Circle

The ''Tractatus'' was now the subject of much debate amongst philosophers, and Wittgenstein was a figure of increasing international fame. In particular, a discussion group of philosophers, scientists and mathematicians, known as the
Vienna Circle The Vienna Circle (german: Wiener Kreis) of Logical Empiricism was a group of philosophers and scientists drawn from the Natural science, natural and Social Sciences, social sciences, logic and mathematics who met regularly from 1924 to 1936 at th ...

writes bluntly: "Wittgenstein was never a member of the Circle, though he was in Vienna during much of the time. Yet his influence on the Circle's thought was at least as important as that of any of its members." However, the philosopher

and, even in these cases, resulted in little lasting effect on their positivism. Grayling states: "...it is no longer possible to think of the ''Tractatus'' as having inspired a philosophical movement, as most earlier commentators claimed." From 1926, with the members of the Vienna Circle, Wittgenstein would take part in many discussions. However, during these discussions, it soon became evident that Wittgenstein held a different attitude towards philosophy than the members of the Circle. For example, during meetings of the Vienna Circle, he would express his disagreement with the group's misreading of his work by turning his back to them and reading poetry aloud. In his autobiography,

describes Wittgenstein as the thinker who gave him the greatest inspiration. However, he also wrote that "there was a striking difference between Wittgenstein's attitude toward philosophical problems and that of Schlick and myself. Our attitude toward philosophical problems was not very different from that which scientists have toward their problems." As for Wittgenstein:


Haus Wittgenstein

In 1926 Wittgenstein was again working as a gardener for a number of months, this time at the monastery of Hütteldorf, where he had also inquired about becoming a monk. His sister, Margaret, invited him to help with the design of her new townhouse in Vienna's ''Kundmanngasse''. Wittgenstein, his friend Paul Engelmann, and a team of architects developed a spare modernist house. In particular, Wittgenstein focused on the windows, doors, and radiators, demanding that every detail be exactly as he specified. When the house was nearly finished Wittgenstein had an entire ceiling raised 30 mm so that the room had the exact proportions he wanted. Monk writes that "This is not so marginal as it may at first appear, for it is precisely these details that lend what is otherwise a rather plain, even ugly house its distinctive beauty." It took him a year to design the door handles and another to design the radiators. Each window was covered by a metal screen that weighed , moved by a pulley Wittgenstein designed. Bernhard Leitner, author of ''The Architecture of Ludwig Wittgenstein'', said there is barely anything comparable in the history of interior design: "It is as ingenious as it is expensive. A metal curtain that could be lowered into the floor." The house was finished by December 1928 and the family gathered there at Christmas to celebrate its completion. Wittgenstein's sister Hermine wrote: "Even though I admired the house very much. ... It seemed indeed to be much more a dwelling for the gods." Wittgenstein said "the house I built for Gretl is the product of a decidedly sensitive ear and ''good'' manners, and expression of great ''understanding''... But ''primordial'' life, wild life striving to erupt into the open – that is lacking." Monk comments that the same might be said of the technically excellent, but austere, terracotta sculpture Wittgenstein had modelled of Marguerite Respinger in 1926, and that, as Russell first noticed, this "wild life striving to be in the open" was precisely the substance of Wittgenstein's philosophical work.


1929–1941: Fellowship at Cambridge


PhD and fellowship

According to Feigl (as reported by Monk), upon attending a conference in Vienna by mathematician L. E. J. Brouwer, Wittgenstein remained quite impressed, taking into consideration the possibility of a "return to Philosophy". At the urging of Ramsey and others, Wittgenstein returned to Cambridge in 1929. Keynes wrote in a letter to his wife: "Well, God has arrived. I met him on the 5.15 train." Despite this fame, he could not initially work at Cambridge as he did not have a degree, so he applied as an advanced undergraduate. Russell noted that his previous residency was sufficient to fulfil eligibility requirements for a PhD, and urged him to offer the ''Tractatus'' as his thesis. It was examined in 1929 by Russell and Moore; at the end of the thesis defence, Wittgenstein clapped the two examiners on the shoulder and said, '"Don't worry, I know you'll never understand it." Moore wrote in the examiner's report: "I myself consider that this is a work of genius; but, even if I am completely mistaken and it is nothing of the sort, it is well above the standard required for the Ph.D. degree." Wittgenstein was appointed as a lecturer and was made a fellow of Trinity College.


Anschluss

From 1936 to 1937, Wittgenstein lived again in Norway, where he worked on the ''Philosophical Investigations''. In the winter of 1936/7, he delivered a series of "confessions" to close friends, most of them about minor infractions like white lies, in an effort to cleanse himself. In 1938, he travelled to Ireland to visit Maurice O'Connor Drury, a friend who became a psychiatrist, and considered such training himself, with the intention of abandoning philosophy for it. The visit to Ireland was at the same time a response to the invitation of the then Irish

, Éamon de Valera, himself a former mathematics teacher. De Valera hoped Wittgenstein's presence would contribute to the Dublin Institute for Advanced Studies which he was soon to set up. While he was in Ireland in March 1938, Germany annexed Austria in the ''Anschluss''; the Viennese Wittgenstein was now a Jew under the Nuremberg Laws, 1935 Nuremberg racial laws, because three of his grandparents had been born as Jews. (He would also, in July, become by law a citizen of the enlarged Germany). The Nuremberg Laws classified people as Jews (''Volljuden'') if they had three or four Jewish grandparents, and as mixed blood (''Mischling'') if they had one or two. It meant ''inter alia'' that the Wittgensteins were restricted in whom they could marry or have sex with, and where they could work. After the Anschluss, his brother Paul left almost immediately for England, and later the US. The Nazis discovered his relationship with Hilde Schania, a brewer's daughter with whom he had had two children but whom he had never married, though he did later. Because she was not Jewish, he was served with a summons for ''Rassenschande'' (racial defilement). He told no one he was leaving the country, except for Hilde who agreed to follow him. He left so suddenly and quietly that for a time people believed he was the fourth Wittgenstein brother to have committed suicide. Wittgenstein began to investigate acquiring British or Irish citizenship with the help of Keynes, and apparently had to confess to his friends in England that he had earlier misrepresented himself to them as having just one Jewish grandparent, when in fact he had three. A few days before the invasion of Poland, Hitler personally granted ''Mischling'' status to the Wittgenstein siblings. In 1939 there were 2,100 applications for this, and Hitler granted only 12. Anthony Gottlieb writes that the pretext was that their paternal grandfather had been the bastard son of a German prince, which allowed the Reichsbank to claim foreign currency, stocks and 1700 kg of gold held in Switzerland by a Wittgenstein family trust. Gretl, an American citizen by marriage, started the negotiations over the racial status of their grandfather, and the family's large foreign currency reserves were used as a bargaining tool. Paul had escaped to Switzerland and then the US in July 1938, and disagreed with the negotiations, leading to a permanent split between the siblings. After the war, when Paul was performing in Vienna, he did not visit Hermine who was dying there, and he had no further contact with Ludwig or Gretl.


Professor of philosophy

After G.E. Moore resigned the chair in philosophy in 1939, Wittgenstein was elected. He was naturalised as a British subject shortly after on 12 April 1939. In July 1939 he travelled to Vienna to assist Gretl and his other sisters, visiting Berlin for one day to meet an official of the Reichsbank. After this, he travelled to New York to persuade Paul, whose agreement was required, to back the scheme. The required ''Befreiung'' was granted in August 1939. The unknown amount signed over to the Nazis by the Wittgenstein family, a week or so before the outbreak of war, included amongst many other assets 1,700 kg of gold. There is a report Wittgenstein visited Moscow a second time in 1939, travelling from Berlin, and again met the philosopher Sofya Yanovskaya, Sophia Janowskaya. Norman Malcolm, at the time a post-graduate research fellow at Cambridge, describes his first impressions of Wittgenstein in 1938: Describing Wittgenstein's lecture programme, Malcolm continues: After work, the philosopher would often relax by watching Western Movie, Westerns, where he preferred to sit at the very front of the cinema, or reading detective stories especially the ones written by Norbert Davis. Norman Malcolm wrote that Wittgenstein would rush to the cinema when class ended. By this time, Wittgenstein's view on the

had changed considerably. In his early 20s, Wittgenstein had thought logic could provide a solid foundation, and he had even considered updating Russell and Alfred North Whitehead, Whitehead's ''Principia Mathematica''. Now he denied there were any mathematical facts to be discovered. He gave a series of lectures on mathematics, discussing this and other topics, documented in a book, with lectures by Wittgenstein and discussions between him and several students, including the young Alan Turing who described Wittgenstein as ''"a ''very'' peculiar man"''. The two had many discussions about the relationship between computational logic and everyday notions of truth. Wittgenstein's lectures from this period have also been discussed by another of his students, the Greek philosopher and educator Elli Lambridi, Helle Lambridis. Wittgenstein's teachings in the years 1940-1941 are used in the mid-1950s by Lambridis to write a long text in the form of an imagined dialogue with him, where she begins to develop her own ideas about resemblance in relation to language, elementary concepts and basic-level mental images. Initially only a part of it was published in 1963 in the German education theory review ''Club Voltaire'', but the entire imagined dialogue with Wittgenstein was published after Lambridis's death by her archive holder, the Academy of Athens (modern), Academy of Athens, in 2004.


1941–1947: Guy's Hospital and Royal Victoria Infirmary

) was going on and he was teaching philosophy. He grew angry when any of his students wanted to become professional philosophers. In September 1941, he asked John Ryle (professor), John Ryle, the brother of the philosopher Gilbert Ryle, if he could get a manual job at Guy's Hospital in London. John Ryle was professor of medicine at Cambridge and had been involved in helping Guy's prepare for the Blitz. Wittgenstein told Ryle he would die slowly if left at Cambridge, and he would rather die quickly. He started working at Guy's shortly afterwards as a dispensary porter, delivering drugs from the pharmacy to the wards where he apparently advised the patients not to take them. In the new year of 1942, Ryle took Wittgenstein to his home in Sussex to meet his wife who had been determined to meet him. His son recorded the weekend in his diary;
Wink is awful strange – not a very good english speaker, keeps on saying 'I mean' and 'its "tolerable"' meaning intolerable.
The hospital staff were not told he was one of the world's most famous philosophers, though some of the medical staff did recognize him – at least one had attended Moral Sciences Club meetings – but they were discreet. "Good God, don't tell anybody who I am!" Wittgenstein begged one of them. Some of them nevertheless called him Professor Wittgenstein, and he was allowed to dine with the doctors. He wrote on 1 April 1942: "I no longer feel any hope for the future of my life. It is as though I had before me nothing more than a long stretch of living death. I cannot imagine any future for me other than a ghastly one. Friendless and joyless." It was at this time that Wittgenstein had an operation at Guy's to remove a gallstone that had troubled him for some years. He had developed a friendship with Keith Kirk, a working-class teenage friend of

, the mathematics undergraduate he had had a relationship with until Skinner's death in 1941 from polio. Skinner had given up academia, thanks at least in part to Wittgenstein's influence, and had been working as a mechanic in 1939, with Kirk as his apprentice. Kirk and Wittgenstein struck up a friendship, with Wittgenstein giving him lessons in physics to help him pass a City and Guilds exam. During his period of loneliness at Guy's he wrote in his diary: "For ten days I've heard nothing more from K, even though I pressed him a week ago for news. I think that he has perhaps broken with me. A ''tragic'' thought!" Kirk had in fact got married, and they never saw one another again. While Wittgenstein was at Guy's he met Basil Reeve, a young doctor with an interest in philosophy, who, with R. T. Grant, was studying the effect of wound shock (a state associative to hypovolaemia) on air-raid casualties. When the blitz ended there were fewer casualties to study. In November 1942, Grant and Reeve moved to the

, to study road traffic and industrial casualties. Grant offered Wittgenstein a position as a laboratory assistant at a wage of £4 per week, and he lived in Newcastle (at 28 Brandling Park, Jesmond) from 29 April 1943 until February 1944. While there he worked and associated socially with Dr Erasmus Barlow, a relative of Charles Darwin. In the summer of 1946, Wittgenstein thought often of leaving Cambridge and resigning his position as Chair. Wittgenstein grew further dismayed at the state of philosophy, particularly about articles published in the journal Mind (journal), ''Mind''. It was around this time that Wittgenstein fell in love with Ben Richards, writing in his diary, "The only thing that my love for B. has done for me is this: it has driven the other small worries associated with my position and my work into the background." On 30 September, Wittgenstein wrote about Cambridge after his return from Swansea, "Everything about the place repels me. The stiffness, the artificiality, the self-satisfaction of the people. The university atmosphere nauseates me." 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. Wittgenstein maintained frequent correspondence with Fouracre during his time away displaying a desire for Fouracre to return home urgently from the war. In May 1947, Wittgenstein addressed a group of Oxford philosophers for the first time at the Jowett Society. The discussion was on the validity of René Descartes, Descartes' ''Cogito ergo sum'', where Wittgenstein ignored the question and applied his own philosophical method. Harold Arthur Prichard who attended the event was not pleased with Wittgenstein's methods;
Wittgenstein: If a man says to me, looking at the sky, 'I think it will rain, therefore I exist', I do not understand him.
Prichard: That's all very fine; what we want to know is: is the ''cogito'' valid or not?


1947–1951: Final years

Wittgenstein resigned the professorship at Cambridge in 1947 to concentrate on his writing, and in 1947 and 1948 travelled to Ireland, staying at Ross's Hotel in Dublin and at a farmhouse in Redcross, County Wicklow, where he began the manuscript MS 137, volume R. Seeking solitude he moved to ''Rosro'', a holiday cottage in Connemara owned by Maurice O'Connor-Drury. He also accepted an invitation from Norman Malcolm, then professor at Cornell University, to stay with him and his wife for several months at Ithaca, New York. He made the trip in April 1949, although he told Malcolm he was too unwell to do philosophical work: "I haven't done any work since the beginning of March & I haven't had the strength of even trying to do any." A doctor in Dublin had diagnosed anaemia and prescribed iron and liver pills. The details of Wittgenstein's stay in America are recounted in Norman Malcolm's ''Ludwig Wittgenstein: A Memoir''. During his summer in America, Wittgenstein began his epistemological discussions, in particular his engagement with philosophical scepticism, that would eventually become the final fragments ''On Certainty''. He returned to London, where he was diagnosed with an inoperable prostate cancer, which had spread to his bone marrow. He spent the next two months in Vienna, where his sister Hermine died on 11 February 1950; he went to see her every day, but she was hardly able to speak or recognize him. "Great loss for me and all of us," he wrote. "Greater than I would have thought." He moved around a lot after Hermine's death staying with various friends: to Cambridge in April 1950, where he stayed with Georg Henrik von WG.H. von Wright; to London to stay with Rush Rhees; then to Oxford to see Elizabeth Anscombe, writing to Norman Malcolm that he was hardly doing any philosophy. He went to Norway in August with Ben Richards, then returned to Cambridge, where on 27 November he moved into ''Storey's End'' at 76 Storey's Way, the home of his doctor, Edward Vaughan Bevan, Edward Bevan, and his wife Joan; he had told them he did not want to die in a hospital, so they said he could spend his last days in their home instead. Joan at first was afraid of Wittgenstein, but they soon became good friends. By the beginning of 1951, it was clear that he had little time left. He wrote a new will in Oxford on 29 January, naming Rhees as his executor, and Anscombe and von Wright his literary administrators, and wrote to Norman Malcolm that month to say, "My mind's completely dead. This isn't a complaint, for I don't really suffer from it. I know that life must have an end once and that mental life can cease before the rest does." In February he returned to the Bevans' home to work on MS 175 and MS 176. These and other manuscripts were later published as ''Remarks on Colour'' and ''On Certainty''. He wrote to Malcolm on 16 April, 13 days before his death:
"An extraordinary thing happened to me. About a month ago I suddenly found myself in the right frame of mind for doing philosophy. I had been ''absolutely'' certain that I'd never again be able to do it. It's the first time after more than 2 years that the curtain in my brain has gone up. – Of course, so far I've only worked for about 5 weeks & it may be all over by tomorrow; but it bucks me up a lot now."


Death

Wittgenstein began work on his final manuscript, MS 177, on 25 April 1951. It was his 62nd birthday on 26 April. He went for a walk the next afternoon, and wrote his last entry that day, 27 April. That evening, he became very ill; when his doctor told him he might live only a few days, he reportedly replied, "Good!" Joan stayed with him throughout that night, and just before losing consciousness for the last time on 28 April, he told her: "Tell them I've had a wonderful life." Norman Malcolm describes this as a "strangely moving utterance". Four of Wittgenstein's former students arrived at his bedside – Ben Richards, Elizabeth Anscombe, Yorick Smythies, and Maurice O'Connor Drury. Anscombe and Smythies were Catholics; and, at the latter's request, a Dominican friar, Father Conrad Pepler, also attended. (Wittgenstein had asked for a "priest who was not a philosopher" and had met with Pepler several times before his death.) They were at first unsure what Wittgenstein would have wanted, but then remembered he had said he hoped his Catholic friends would pray for him, so they did, and he was pronounced dead shortly afterwards. Wittgenstein was given a Catholic burial at Ascension Parish Burial Ground in Cambridge. Drury later said he had been troubled ever since about whether that was the right thing to do. In 2015 the ledger gravestone was refurbished by the British Wittgenstein Society. On his religious views, Wittgenstein was said to be greatly interested in Catholicism, and was sympathetic to it. However, he did not consider himself to be a Catholic. According to Norman Malcolm, Wittgenstein saw Catholicism more as a way of life than as a set of beliefs he personally held, considering that he did not accept any religious faith.
Wittgenstein has no goal to either support or reject religion; his only interest is to keep discussions, whether religious or not, clear. — T. Labron (2006)
Wittgenstein was said by some commentators to be agnostic, in a qualified sense.


1953: Publication of the ''Philosophical Investigations''

The ''Blue and Brown Books, Blue Book'', a set of notes dictated to his class at Cambridge in 1933–1934, contains the seeds of Wittgenstein's later thoughts on language and is widely read as a turning-point in his philosophy of language. ''Philosophical Investigations'' was published in two parts in 1953. Most of Part I was ready for printing in 1946, but Wittgenstein withdrew the manuscript from his publisher. The shorter Part II was added by his editors, Elizabeth Anscombe and Rush Rhees. Wittgenstein asks the reader to think of language as a multiplicity of language-games within which parts of language develop and function. He argues the bewitchments of philosophical problems arise from philosophers' misguided attempts to consider the meaning of words independently of their context, usage, and grammar, what he called "language gone on holiday". According to Wittgenstein, philosophical problems arise when language is forced from its proper home into a metaphysical environment, where all the familiar and necessary landmarks and contextual clues are removed. He 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. Wittgenstein argues that philosophers must leave the frictionless ice and return to the "rough ground" of ordinary language in use. Much of the ''Investigations'' consists of examples of how the first false steps can be avoided, so that philosophical problems are dissolved, rather than solved: "The clarity we are aiming at is indeed ''complete'' clarity. But this simply means that the philosophical problems should ''completely'' disappear."


Other posthumous publications

Wittgenstein left a voluminous archive of unpublished papers, including 83 manuscripts, 46 typescripts and 11 dictations, amounting to an estimated 20,000 pages. Choosing among repeated drafts, revisions, corrections, and loose notes, editorial work has found nearly one third of the total suitable for print. An Internet facility hosted by the University of Bergen allows access to images of almost all the material and to search the available transcriptions. In 2011, two new boxes of Wittgenstein papers, thought to have been lost during the Second World War, were found. What became the ''

'' was already close to completion in 1951. Wittgenstein's three literary executors prioritized it, both because of its intrinsic importance and because he had explicitly intended publication. The book was published in 1953. At least three other works were more or less finished. Two were already "bulky typescripts", the ''Philosophical Remarks'' and ''Philosophical Grammar''. Literary (co-)executor G. H. von Wright revealed "They are virtually completed works. But Wittgenstein did not publish them." The third was ''Remarks on Colour''. "He wrote ''inter alia, i.a.'' a fair amount on colour concepts, and this material he did excerpt and polish, reducing it to a small compass."

As mentioned above, in 1999 a survey among American university and college teachers ranked the ''Investigations'' as the most important book of 20th-century philosophy, standing out as "the one crossover masterpiece in twentieth-century philosophy, appealing across diverse specializations and philosophical orientations." The ''Investigations'' also ranked 54th on a list of most influential twentieth-century works in cognitive science prepared by the University of Minnesota's Center for Cognitive Sciences. Peter Hacker argues that Wittgenstein's influence on 20th-century analytical philosophy can be attributed to his early influence on the

and later influence on the Oxford Ordinary language philosophy, "ordinary language" school and Cambridge philosophers. Despite its deep influence on analytical philosophy, Wittgenstein's work did not always gain a positive reception.


Scholarly interpretation

There are diverging interpretations of Wittgenstein's thought. In the words of his friend and colleague
Georg Henrik von Wright 220px, Von Wright's home on Laivurinkatu Street, Helsinki: a commemorative plaque marking his long-term residence was installed in 2006 Georg Henrik von Wright (; 14 June 1916 – 16 June 2003) was a Finnish philosopher A philosopher is so ...
:
He was of the opinion ... that his ideas were generally misunderstood and distorted even by those who professed to be his disciples. He doubted he would be better understood in the future. He once said he felt as though he was writing for people who would think in a different way, breathe a different air of life, from that of present-day men.
Since Wittgenstein's death, scholarly interpretations of his philosophy have differed. Scholars have differed on the continuity between the so-called early Wittgenstein and the so-called late(r) Wittgenstein (that is, the difference between his views expressed in the ''Tractatus'' and those in ''Philosophical Investigations''), with some seeing the two as starkly disparate and others stressing the gradual transition between the two works through analysis of Wittgenstein's unpublished papers (the ''Nachlass''). One significant debate in Wittgenstein scholarship concerns the work of interpreters who are referred to under the banner of The New Wittgenstein school such as Cora Diamond, Alice Crary, and James F. Conant. While the ''Tractatus'', particularly in its conclusion, seems paradoxical and self-undermining, New Wittgenstein scholars advance a "therapeutic" understanding of Wittgenstein's work – "an understanding of Wittgenstein as aspiring, not to advance metaphysical theories, but rather to help us work ourselves out of confusions we become entangled in when philosophizing." To support this goal, the New Wittgenstein scholars propose a reading of the ''Tractatus'' as "plain nonsense" – arguing it does not attempt to convey a substantive philosophical project but instead simply tries to push the reader to abandon philosophical speculation. The therapeutic approach traces its roots to the philosophical work of John Wisdom and the review of ''The Blue Book'' written by Oets Kolk Bouwsma. The therapeutic approach is not without critics: Hans-Johann Glock argues that the "plain nonsense" reading of the ''Tractatus'' "is at odds with the external evidence, writings and conversations in which Wittgenstein states that the ''Tractatus'' is committed to the idea of ineffable insight."


Bertrand Russell

In October 1944, Wittgenstein returned to Cambridge around the same time as did Russell, who had been living in United States, America for several years. Russell returned to Cambridge after a backlash in America to his writings on morals and religion. Wittgenstein said of Russell's works to Drury:
Russell's books should be bound in two colours…those dealing with mathematical logic in red – and all students of philosophy should read them; those dealing with ethics and politics in blue – and no one should be allowed to read them.
Russell made similar disparaging comments about Wittgenstein's later work:
I have not found in Wittgenstein's ''Philosophical Investigations'' anything that seemed to me interesting and I do not understand why a whole school finds important wisdom in its pages. Psychologically this is surprising. The earlier Wittgenstein, whom I knew intimately, was a man addicted to passionately intense thinking, profoundly aware of difficult problems of which I, like him, felt the importance, and possessed (or at least so I thought) of true philosophical genius. The later Wittgenstein, on the contrary, seems to have grown tired of serious thinking and to have invented a doctrine which would make such an activity unnecessary. I do not for one moment believe that the doctrine which has these lazy consequences is true. I realize, however, that I have an overpoweringly strong bias against it, for, if it is true, philosophy is, at best, a slight help to lexicographers, and at worst, an idle tea-table amusement.


Saul Kripke

Saul Kripke's 1982 book ''Wittgenstein on Rules and Private Language'' contends that the central argument of Wittgenstein's ''

'' is a devastating rule-following paradox that undermines the possibility of our ever following rules in our use of language. Kripke writes that this paradox is "the most radical and original sceptical problem that philosophy has seen to date." Kripke's book generated a large secondary literature, divided between those who find his sceptical problem interesting and perceptive, and others, such as Gordon Baker, Peter Hacker, Colin McGinn, and Peter Winch who argue that his scepticism of meaning is a pseudo-problem that stems from a confused, selective reading of Wittgenstein. Kripke's position has, however recently been defended against these and other attacks by the Cambridge philosopher Martin Kusch (2006).
