Overview
Ludwig Wittgenstein (1889–1951), born in Vienna to a wealthy industrial family, studied engineering then logic with Russell at Cambridge. The Tractatus Logico-Philosophicus (1921) aimed to draw limits to sense; he then left academic philosophy for years as a teacher and architect’s assistant. Returning to Cambridge, he developed a later philosophy published posthumously as Philosophical Investigations. He served in World War I and lived with austere intensity. Handbook dates: 1889–1951. Few thinkers so thoroughly reinvented their own method mid-career.
Main ideas
The Tractatus links meaningful propositions to logical pictures of states of affairs and consigns ethics and the mystical to silence beyond sense. Later work rejects a single essence of language: meaning is use within language-games embedded in forms of life. Philosophical problems often arise from linguistic bewitchment—stretching words beyond their ordinary homes. Rule-following and private language arguments challenge pictures of meaning as inner ostension. Therapy replaces theory-building: the aim is to dissolve confusion, not erect a new system. Logic and mathematics are activities within practices, not mirrors of a crystalline world beyond.

Legacy
He redirected twentieth-century philosophy of language, mind, logic, and ordinary practice across analytic traditions. Ordinary-language philosophy, therapeutic readings, and quietism all claim his inheritance. Artists and social theorists also appropriated language-game imagery.
