Ludwig Wittgenstein (1889-1951) was an Austrian-British philosopher who produced two revolutionary philosophical works: the Tractatus Logico-Philosophicus (1921) and the Philosophical Investigations (published posthumously in 1953). The first attempted to define the limits of language and thought; the second dismantled the first's assumptions and reimagined language as a social practice.

What Does the Tractatus Argue?

The Tractatus proposes that language pictures the world and that the limits of language are the limits of thought. It concludes with the famous proposition: "Whereof one cannot speak, thereof one must be silent." Wittgenstein believed it solved all philosophical problems and left philosophy entirely.

What Are the Philosophical Investigations?

Wittgenstein returned to philosophy after realizing the Tractatus was wrong. The Investigations argues that meaning is not a picture of reality but a function of use within "language games." Words mean what they do in practice, not what they point to in theory. This insight transformed philosophy of language, mind, and social science.

What Was Wittgenstein's Life Like?

Wittgenstein was born into one of Vienna's wealthiest families and gave away his inheritance. He served in World War I, worked as a village schoolteacher and hospital porter, designed a house for his sister, and returned to Cambridge to teach. His personal intensity was legendary; he agonized over his work and his moral life.
