Works & Achievements

Notes dictated to his students that begin the turn toward his later philosophy, centred on the ordinary use of language.
His posthumous masterpiece, introducing the notions of “language-games” and use, which criticises his own early philosophy.
Posthumous reflections on doubt, knowledge and the certainties that form the background of all thought.
Posthumous notes questioning the nature of rules, proof and necessity in mathematics.
A modernist house he designed for his sister, illustrating his pursuit of rigour and austerity applied to architecture.
Anecdotes
Born into one of the wealthiest families in Austria, Wittgenstein inherited an immense fortune when his father died in 1913. After the First World War, he decided to give it all away — notably to his already wealthy brothers and sisters — in order to live simply and no longer depend on money.
During the First World War, he volunteered for the Austro-Hungarian army and wrote much of his first great book, the *Tractatus logico-philosophicus*, in the trenches and even in captivity as a prisoner of war in Italy.
Convinced after the *Tractatus* that he had solved the essential problems of philosophy, Wittgenstein abandoned the discipline and became a schoolteacher in remote Austrian villages between 1920 and 1926. He even wrote a spelling dictionary for his pupils.
An amateur architect, he designed a modernist house in Vienna for his sister Margaret together with the architect Paul Engelmann between 1926 and 1928, attending to every detail, from the door handles to the radiators, with almost obsessive rigour.
At Cambridge, his lectures were famous: he taught without notes, seated on a plain folding chair in an almost empty room, thinking aloud in front of his students at the cost of long silences and visible effort.
