The ultimate enigma of 20th-century philosophy. He authored "Tractatus Logico-Philosophicus" in war trenches, then dismantled it in "Philosophical Investigations" to initiate ordinary language philosophy.
Perhaps the most enigmatic philosopher of the twentieth century. Born into one of Europe's wealthiest and most cultured families in Vienna, he gave away his inheritance, lived in extreme austerity, and worked variously as an engineer, schoolteacher, gardener, and hospital porter. His early Tractatus Logico-Philosophicus, written in the trenches of World War I, was the only book he published in his lifetime. He believed he had solved all philosophical problems—and abandoned philosophy for years. He returned to Cambridge in 1929 and spent his remaining two decades dismantling his own earlier work, producing the Philosophical Investigations posthumously. He died after losing consciousness with the words: "Tell them I've had a wonderful life."
The early Wittgenstein argued that language is a picture of reality: propositions mirror the logical structure of facts, and the limits of language are the limits of the world. "Whereof one cannot speak, thereof one must be silent." The later Wittgenstein demolished this view. He argued that language is not a single unified picture-making system but a family of "language-games"—diverse practices governed by their own internal rules. Meaning is not reference to objects but use within a form of life. Philosophical problems arise when language "goes on holiday"—when words are torn from their ordinary contexts and forced into metaphysical abstraction. The task of philosophy is not to build theories but to dissolve confusions by reminding us how language actually works.
"The limits of my language mean the limits of my world. — (Early) The meaning of a word is its use in the language. Philosophical problems arise when language goes on holiday. — (Late)"
His early work advises us: "Stop talking about things you cannot logically prove." His late work advises: "Get out of the ivory tower and engage in the games of real life." Do you construct your own conceptual "fly-bottles" of despair by demanding absolute definitions of things like "perfect happiness"? Can you find relief by simply engaging in concrete, everyday activities like cooking, sweeping, or helping a neighbor?
Frege believed that an ideal logical language could perfectly represent the structure of thought. Wittgenstein began in agreement, then executed a stunning reversal: there is no ideal language, only the multiplicity of language-games. Philosophy's task is not to perfect a formal system but to untangle the knots we create by misusing ordinary language.
Is there a single logical structure underlying all meaningful language, or is language an irreducibly plural family of practices, each with its own rules that cannot be reduced to or judged by any one of the others?
