The Turn: From the Tractatus to the Critique of Logical Empiricism

The late Wittgenstein cannot be understood without his engagement with the Vienna Circle. The Philosophical Investigations (published posthumously in 1953) are not only a self-critique of the Tractatus, but at the same time a radical critique of the entire project of logical empiricism—a project that had invoked Wittgenstein’s early work.

The dramatic irony: the Vienna Circle read the Tractatus as the founding manifesto of scientific philosophy. Wittgenstein himself increasingly distanced himself from this interpretation. The dialogues between Wittgenstein and members of the Circle (1927–1932) were marked by mutual misunderstanding. Schlick and Waismann tried to win Wittgenstein over for their program. In these very conversations, Wittgenstein developed precisely the insights that would undermine that program.[1]

What Wittgenstein criticized in the Vienna Circle:

  1. The idea of an ideal language: the Circle sought a logically perfect language that pictures the structure of reality. Wittgenstein recognized: that is an illusion. There is not one language, but many languages—language games with different purposes and rules.

  2. The verification principle: the reduction to empirical verification is too narrow. Meaning arises not through picturing or verification, but through use in concrete practices. The sentence “I am in pain” is not verifiable through observation (no one but me can observe my pain), yet it is meaningful nonetheless.

  3. The separation of logic and empirical matters: the Circle strictly separated analytic (logical) from synthetic (empirical) sentences. Wittgenstein saw: this separation is artificial. The boundaries are fluid. What we call “logical” is often only a very firmly established rule of our language games.

  4. The idea of protocol sentences: the attempt to reduce all statements to protocol sentences about immediate experience fails. There are no “pure” observation sentences without conceptual interpretation. All experience is always already linguistically structured.

The systematic turn: Wittgenstein carried out a pragmatic turn. No longer is the question “What is the logical structure of language?” at the center, but rather: “How do we actually use language? What games do we play? What rules apply in various contexts?”

The Plurality of Language Games — The Dissolution of the One Logic

The central innovation of the late Wittgenstein is the concept of language games. A language game is a practice of speaking, embedded in a form of life—a way of living, acting, interacting.[2]

Examples of various language games:

  • Giving orders and acting on orders
  • Describing an object by its appearance or its measurements
  • Constructing an object from a description
  • Reporting an event
  • Speculating about an event
  • Forming and testing a hypothesis
  • Making up a story and reading it
  • Play-acting
  • Making and telling a joke
  • Solving a riddle
  • Expressing a wish
  • Asking for something
  • Thanking, cursing, greeting, praying

Each of these language games has its own rules. There is no meta-rule that encompasses all language games. There is no “essence” of language shared by all.[3]

The challenge to logical empiricism: the verification principle may hold for scientific statements—but it is itself only one language game among many. Ethical statements, aesthetic judgments, religious confessions follow other rules. They are not “meaningless” merely because they are not empirically verifiable—they play different language games.

The challenge to Hegel: if there is no unified structure of reason, if different language games are incommensurable, if every form of life has its own standards—how is systematic philosophy still possible? Hegel’s claim to explicate the structures of reason as such seems absurd. There is no “reason as such,” only various, equally legitimate forms of rationality.

Family Resemblances instead of Essentialism — The Critique of the Dialectic of Universality

Wittgenstein developed the concept of family resemblance as an alternative to the traditional theory of definition—and thus also to Hegel’s dialectic of universality.[4]

The classic example: what is a “game”? One looks for the common property that all games share—and finds none. Board games, ball games, card games, the Olympic Games—they have no common essence. Instead there is a network of similarities: some games have winners, others do not. Some are based on skill, others on luck. Some are entertaining, others serious. Like family members who show similarities (same nose, same eyes, same hair color) without all sharing the same features.

The critique of Hegel: Hegel’s “concept” is concrete universality—the unity of the universal, the particular, and the individual. The concept of the human being is not an abstract property, but the structure that realizes itself individually in every human being. The concept is alive, developing, concrete.

Wittgenstein says: often there is no universality at all—only a loose network of similarities. One cannot say what “game” is—one can only describe various games and show similarities. The attempt to find a unified definition leads to empty abstractions.

The systematic difference:

  • Hegel: from the abstract (formal universality) via the particular (differentiation) to the individual (concrete realization). The concept develops dialectically.
  • Wittgenstein: there is no development, no dialectic. There is only the description of the various uses. Philosophy is not theory, but description.

“Philosophy Leaves Everything as It Is” — The Therapeutic Turn

The most radical consequence of Wittgenstein’s late philosophy is the renunciation of philosophical theory. Philosophy’s task is not to explain, to ground, to systematize—but to describe and clarify.[5]

The famous thesis: “Philosophy may in no way interfere with the actual use of language, so it can in the end only describe it. […] It leaves everything as it is.” (Philosophical Investigations, §124)

The therapeutic conception: philosophical problems are confusions of language. They arise when we tear language out of its natural context and ask about “the essence.” Philosophy’s task is not to solve these problems, but to dissolve them—to show that they rest on misunderstandings.

The critique of the Vienna Circle: the Circle wanted to “overcome” metaphysics through a positive program—the verification principle, protocol language, the unified language of science. But this program is itself metaphysical. It sets standards that cannot be grounded. It wants to make philosophy scientific—but science itself is just one language game among many.

The critique of Hegel: Hegel’s system wants to explicate the structures of reason, to develop the categories, to reach the Absolute. But that is a metaphysical project. It presupposes that there is a hidden depth that philosophy must uncover. Wittgenstein says: there is no hidden depth. Everything lies open. Philosophy need only remove the confusions that prevent us from seeing what is open.

The Limits of Wittgensteinian Pluralism — The Systematic Question

Wittgenstein’s late philosophy is a radical challenge to any systematic philosophy—including a renewed dialectic. But it also has systematic limits:

1. The impossibility of critique: if every language game has its own rules and there are no overarching standards—how then is critique possible? Wittgenstein says: “If I contest another’s following of a rule, I must be able to say wherein he deviates.” But if different language games are incommensurable, there is no common basis for critique.

Example: a religious language game has different rules from a scientific one. If I say “God exists,” I am playing a different game than if I say “Electrons exist.” The question “Does God really exist?” presupposes that both statements belong to the same language game—but they do not. So the question is meaningless. But is this not a free pass for irrationalism? Every language game could evade critique by pointing out: “You’re playing a different game.”

2. The self-application of the concept: is Wittgenstein’s own philosophy not itself a language game? If so, why should it be privileged? Wittgenstein answers: philosophy is not a theory, but an activity—it is like a ladder that one throws away after using it. But this is the same paradox as in the Tractatus. Philosophy refutes itself.

3. The question of the conditions of possibility: Wittgenstein describes various language games. But he does not ask: what structures must be presupposed for various language games to be possible at all? This transcendental question—Kant’s and Hegel’s question—is not posed by Wittgenstein. But it is unavoidable if one does not want to remain in mere pluralism.
