Born into one of the wealthiest families in Europe, he gave his entire inheritance away to his siblings and various artists. He wrote the most important work in 20th century philosophy while serving as an artilleryman in World War I, had it published, then quit philosophy believing he had solved all its problems, and became a village schoolteacher. Years later he returned to Cambridge, decided the Tractatus was entirely wrong, and spent the rest of his life building a completely different philosophy. His last words were: "Tell them I've had a wonderful life."

Chapter 1 · Manchester to Cambridge, 1911 · Finding Russell
You are 22. You have been studying engineering — aeronautics in Manchester, working on jet propulsion designs. But you have become obsessed with the foundations of mathematics. You read Frege. You read Russell's Principles of Mathematics. A question has formed in you that engineering cannot answer: what is the nature of logic itself? You take your engineering notebooks to Frege in Jena, show him your work. He tells you to go to Cambridge and find Bertrand Russell. You leave Manchester and go. You interrupt Russell's office hours. You argue with him for two hours. Russell writes in his diary that evening that he thinks you might be a genius.
Decision 1 · The Change
You are a capable engineer. The questions that are consuming you are philosophical, not engineering. Do you abandon engineering entirely?
What actually happened: Wittgenstein abandoned engineering and went to Cambridge. Russell initially asked him, after his first term, whether he thought of himself as a genius or an idiot — because if he was an idiot he should continue in philosophy, but if he was a genius he should stop. Wittgenstein asked Russell to look at something he had written over the vacation. Russell read it and told him immediately: stop worrying, you are not an idiot. Wittgenstein spent two years at Cambridge before WWI broke out, during which he developed the core ideas that would become the Tractatus.
Chapter 2 · The Eastern Front, 1914–1918 · Writing in the Trenches
You have volunteered for the Austrian army at the outbreak of war — you could have been exempted but you chose not to be. You believe the experience of danger will transform you morally. You are posted to the Eastern Front, then to Italy. You carry Tolstoy's Gospel in Brief in your pack. You are writing a philosophical manuscript in notebooks that you keep in your military kit. On the Italian Front in 1918, shortly before the armistice, you are taken prisoner by the Italians at Cassino. The manuscript is complete. It is the Tractatus Logico-Philosophicus. You have written it while doing your duty as a soldier. You don't know yet what you've made.
Decision 2 · The Tractatus
You believe you have solved the central problems of philosophy in the Tractatus. The book ends: "Whereof one cannot speak, thereof one must be silent." Do you send it to publishers from the prisoner of war camp?
What actually happened: Wittgenstein sent the manuscript to Russell from the POW camp and then worked with him intensively on getting it published. Russell wrote an introduction that Wittgenstein considered inadequate and which he accepted with reservations. The book was eventually published in 1921 in German and 1922 in English translation with Russell's introduction. It was received as one of the most important philosophical works of the century. Wittgenstein read the reviews and concluded that no one understood what he had actually written. He was probably right.
Chapter 3 · Vienna, 1920 · The Fortune
Your father Karl Wittgenstein was one of the great industrialists of the Austro-Hungarian Empire — the Carnegie of Austria. He died in 1913. The family fortune is immense. Your inheritance alone would make you wealthy for the rest of your life. The Tractatus is published. You believe you have solved the problems of philosophy. You also believe that philosophy was a kind of therapy — now that it is finished, there is no need to keep doing it. You want to live more simply. You want to give the money away.
Decision 3 · The Fortune
You have inherited vast wealth. You want to give it away. Do you?
What actually happened: Wittgenstein gave away his entire fortune — he had already given significant sums to artists and writers including Rilke, Georg Trakl, and Oskar Kokoschka during the war. The remainder went to his siblings. He kept nothing. He went on to train as an elementary school teacher and spent six years teaching village children in rural Austria. He lived in a single room. He was intensely demanding of his students — some of his methods of physical discipline led to a legal case — and eventually left teaching in 1926. He then worked as a gardener's assistant at a monastery. The money was gone and he did not miss it.
Chapter 4 · Vienna, 1927 · The Vienna Circle
You have been teaching children and building houses and working as a gardener. Philosophers in Vienna — the Vienna Circle, led by Moritz Schlick — have been reading your Tractatus and treating it as the foundational text of logical positivism: the view that meaningful statements are either analytic (true by definition) or empirically verifiable. They invite you to meet with them. You come reluctantly. They are intelligent but they have misread you almost completely — they think the Tractatus is an argument for their position when it is in many ways a critique of the very ambitions logical positivism represents. You sit with them and sometimes turn your back and read Rabindranath Tagore aloud instead of discussing their questions.
Decision 4 · The Vienna Circle
The most influential philosophical movement in Europe has adopted your work as their scripture, but they have misunderstood it. Do you correct them?
What actually happened: Wittgenstein engaged with the Vienna Circle on his own terms — attending selectively, correcting their readings directly in conversation, and gradually developing the thinking that would become the Philosophical Investigations. The process of seeing how intelligent philosophers had misread the Tractatus was itself philosophically useful: it showed him what the Tractatus had gotten wrong about language and meaning. The Vienna Circle's misreading was the problem that generated the solution. By the late 1920s he was back in philosophy full-time and returning to Cambridge.
Chapter 5 · Cambridge, 1929–1947 · The Second Philosophy
You return to Cambridge. You submit the Tractatus as your doctoral dissertation (Russell and G.E. Moore examine you; Russell later says it was the most unusual doctoral examination he had ever conducted). You become a Professor of Philosophy in 1939, succeeding Moore. But the work you are doing is completely different from the Tractatus — you are now arguing that the Tractatus was wrong in its fundamental approach. Language is not a logical picture of the world. Meaning comes from use in forms of life. "Whereof one cannot speak, thereof one must be silent" is replaced by a more patient attention to how language actually works in practice. The new philosophy is slower, less dramatic, and more difficult.
Decision 5 · Showing the Tractatus Was Wrong
Your early masterpiece has made your reputation. The new philosophy shows it was mistaken in fundamental ways. Do you say so clearly?
What actually happened: Wittgenstein was explicit that the new work corrected the old. The preface to the Philosophical Investigations directly addresses the Tractatus: he says he recognizes that what he wrote in that book is "full of mistakes" and that seeing those mistakes was only possible by being in contrast with new thinking. The Philosophical Investigations begins with a quotation from Augustine about language acquisition and proceeds to dismantle the picture theory of language that the Tractatus had assumed. It is one of the few examples in intellectual history of a thinker publishing a clear refutation of their own previous masterwork.
Chapter 6 · Newcastle, 1941 · The Hospital
During the Second World War you want to do something useful. You do not want to lecture philosophy while people are dying. You take a position as a dispensary porter at the Royal Victoria Infirmary in Newcastle — mixing drugs and delivering them to wards. You work there for several years. Nurses who worked with you during the war remembered you decades later as a gentle and careful colleague who gave excellent advice about which drugs to use for which symptoms. You have read extensively in medicine as in everything else. You do not mention that you are the most important philosopher in the world.
Decision 6 · The War Work
You choose to work as a hospital porter rather than lecture philosophy during the war. Is this the right choice?
What actually happened: Wittgenstein spent two years as a hospital dispenser in Newcastle and later as a laboratory assistant in London. His medical colleagues found him extraordinarily competent and kind. He reportedly discouraged patients from taking what he considered unnecessary medications and gave direct, useful advice about their symptoms. When the war ended he returned to Cambridge but increasingly found academic philosophy intolerable — the seminars, the papers, the professional machinery. He resigned his Chair in 1947 and moved to Ireland to work alone. He had been a professor for eight years. He did not miss it.
Chapter 7 · Ireland and Cambridge, 1947–1951 · The Dying
You resign the Cambridge Chair in 1947 and move to Ireland to work in solitude near Galway. The Philosophical Investigations is essentially complete but you will not publish it. You are afraid it will be misunderstood as badly as the Tractatus. In 1949 you are diagnosed with prostate cancer. You return to England and continue working — on color, on certainty, on the limits of doubt. You work until very near the end. On April 28, 1951, told that friends will be coming to see you the next day, you say: "Tell them I've had a wonderful life." You die that night in Cambridge.
Decision 7 · Not Publishing the Investigations
The Philosophical Investigations is complete. You are afraid it will be misread. Do you publish it?
What actually happened: Wittgenstein did not publish the Philosophical Investigations in his lifetime. His literary executors — G.E.M. Anscombe and Rush Rhees — published it in 1953, two years after his death, in a bilingual German-English edition with Anscombe's translation. It was recognized immediately as a major work. It changed the direction of analytic philosophy and influenced ordinary language philosophy, philosophy of mind, philosophy of psychology, and linguistics. It has been in continuous print ever since. Whether he would have published it himself, given more time, is unknown. He was still revising it in his final months.
Chapter 8 · The Legacy
Ludwig Wittgenstein produced two distinct masterworks that point in completely opposite directions — the Tractatus and the Philosophical Investigations — and explicitly said the first was mistaken. Together they shaped analytic philosophy for the entire 20th century and continue to define what philosophical questions about language, meaning, and mind look like. He gave away a fortune. He quit philosophy and then came back to it. He told a hospital ward that he had had a wonderful life, on the last night of it.
Decision 8 · Two Philosophies
He produced the Tractatus and the Investigations — two completely different philosophical masterworks. Which matters more?
What actually happened: Philosophers argue about this perpetually. The Tractatus is more famous outside philosophy; the Investigations is more influential within it. What both share is the quality of absolute seriousness — Wittgenstein did not write a sentence he did not believe with total conviction. The Tractatus ends "Whereof one cannot speak, thereof one must be silent." The Investigations begins, in effect, with the question: but what does speaking actually consist of? Twenty years separate the two questions. The life between them — the village schoolteacher, the hospital porter, the gardener, the man who gave everything away — is as much his philosophy as either book.
