Central Problem
The central problem addressed by Wittgenstein’s philosophy is the relationship between language, thought, and reality. What are the limits of what can meaningfully be said? How does language connect to the world it describes? And what is the proper role of philosophy in clarifying or dissolving conceptual confusions?
In his early work, the Tractatus Logico-Philosophicus (1921), Wittgenstein sought to determine the logical structure that language must possess in order to represent reality. The key insight is that there is no intermediate sphere of “thought” or “knowledge” mediating between world and language — thought simply is language, and language is the logical picture of reality. This leads to a radical delimitation: whatever cannot be expressed in meaningful propositions must be passed over in silence, including ethics, aesthetics, metaphysics, and the very conditions that make language possible.
In his later work, the Philosophical Investigations (published posthumously 1953), Wittgenstein abandons the idea of a single logical structure underlying all language. Instead, he recognizes language as a multiplicity of “language games” — different rule-governed practices serving different purposes. The question shifts from “What is the essence of language?” to “How is language actually used?” Philosophy’s task becomes therapeutic: dissolving pseudo-problems that arise from misunderstanding how language works.
Main Thesis
Early Wittgenstein (Tractatus):
The Tractatus advances a picture theory of language: propositions are logical pictures of facts. The world consists of facts (states of affairs), not things; facts are combinations of simple objects. Propositions mirror the logical structure of facts — they share a common “logical form” with what they represent.
Key claims include:
- Thought = Language: “The logical picture of facts is the thought” (prop. 3). There is no separate mental realm; thinking is the manipulation of propositions.
- Atomic propositions represent atomic facts; complex propositions are truth-functions of atomic ones.
- Tautologies (like “It is raining or not raining”) are necessarily true but say nothing about the world; they show logical structure.
- Contradictions are necessarily false and equally non-informative.
- Meaningful propositions describe possible states of affairs; their truth depends on whether those states obtain.
- Nonsense results from violating logical syntax — attempting to say what can only be shown.
The limits of language are the limits of the world: “What we cannot speak about we must pass over in silence” (prop. 7). Ethics, aesthetics, the meaning of life, and the “mystical” cannot be stated, only shown.
Later Wittgenstein (Philosophical Investigations):
The later work rejects the idea of one ideal logical language. Instead:
- Meaning is use: “If we had to name anything which is the life of the sign, we should have to say that it was its use.”
- Language games: Language consists of diverse, rule-governed practices — describing, commanding, questioning, thanking, cursing, praying, etc. Each game has its own rules; there is no single essence.
- Family resemblances: Different language games are related like members of a family — overlapping similarities without a common core.
- Philosophy as therapy: Philosophical problems arise when “language goes on holiday” — when words are torn from their everyday use. Philosophy’s role is to return words to their ordinary use, dissolving rather than solving problems.
- Against private language: Meaning is public and social; a purely private language is impossible because there would be no criterion for correct use.
Historical Context
Wittgenstein was born in Vienna in 1889 into one of Europe’s wealthiest families (steel magnates). Initially trained as an engineer in Berlin and Manchester, his interest shifted to the foundations of mathematics. The decisive encounter came in 1911 when he met Frege in Jena, who directed him to Cambridge to study with Russell.
At Cambridge (1912-1913), Wittgenstein engaged intensively with Russell, who was publishing the Principia Mathematica. Their relationship became one of mutual influence — Russell credited Wittgenstein with key insights about the tautological nature of logic.
In 1913 Wittgenstein retreated to Norway in solitude. When World War I broke out, he enlisted in the Austrian army and was captured by Italians in 1918. While imprisoned near Cassino, he completed the Tractatus. The work appeared in German in 1921 and in English (with Russell’s introduction) in 1922.
After the war, believing he had solved the essential problems of philosophy, Wittgenstein abandoned academic life. He gave away his inheritance, worked as an elementary school teacher in rural Austria (1920-1926), then as a gardener and architect (designing his sister’s house in Vienna with architect Engelmann — a building that embodied the Tractatus’s principles of logical clarity and absence of ornament).
In 1929, encouraged by his friends and the Vienna Circle philosophers who had adopted the Tractatus as foundational, Wittgenstein returned to Cambridge. He became professor in 1939 (succeeding Moore) and obtained British citizenship after Austria’s annexation by Nazi Germany. During World War II he worked as a hospital orderly.
From the early 1930s, Wittgenstein began radically revising his earlier views, influenced by discussions with Ramsey, Brouwer, and members of the Vienna Circle. The Philosophical Investigations, composed between 1935-1949, was published posthumously in 1953. Wittgenstein died of prostate cancer in 1951.

Summary Formulas
-
Wittgenstein (Tractatus): Language is the logical picture of reality; what can be said can be said clearly, and what cannot be spoken of must be passed over in silence — philosophy’s task is to delimit the thinkable by clarifying the limits of language.
-
Wittgenstein (Investigations): Meaning is use within language games; philosophy’s role is therapeutic — dissolving pseudo-problems that arise when language goes on holiday, returning words from metaphysical abstraction to their ordinary employment.
-
Russell: Logical analysis can reveal the true logical form hidden beneath the misleading grammatical surface of ordinary language, enabling the construction of a philosophically perspicuous notation.
