Language as a Philosophical Problem

Why did language become the central philosophical concern of the twentieth century? Several reasons converge. First, the discovery that many classical philosophical problems resulted from linguistic confusions — misunderstandings about the logical form of propositions. Second, the recognition that understanding how language works is understanding how we think and how we relate to the world. Third, the logical revolution initiated by Frege, which provided rigorous tools for linguistic analysis.

Frege: Sense and Reference

Gottlob Frege (1848–1925) is the starting point. In “On Sense and Reference” (Über Sinn und Bedeutung, 1892), he distinguishes two aspects of linguistic expressions:

  • Reference (Bedeutung): the object to which the expression refers
  • Sense (Sinn): the mode of presentation of the object

The problem: “The Morning Star” and “The Evening Star” refer to the same object (the planet Venus). But the two expressions have different senses — they present the object in different ways. This is why the identity “The Morning Star is the Evening Star” is informative (an astronomical discovery), while “The Morning Star is the Morning Star” is trivially true.

This distinction is fundamental: it explains how we can have true or false beliefs about the same object and how identity statements have informative value.

Russell: Descriptions and Logical Form

Bertrand Russell (1872–1970), in “On Denoting” (1905), analyzes definite descriptions — expressions like “the present King of France.” The question: “The present King of France is bald” — true or false?

Pre-analytic intuition hesitates: it seems to presuppose that there is a present King of France, which is false. Russell proposes that the real logical form is: “There exists exactly one x such that x is the present King of France, and x is bald.” This analysis eliminates the existential presupposition from the surface grammar and makes the statement simply false when no such king exists.

The lesson: the grammatical form of sentences can mislead about their actual logical form. Philosophy must analyze propositions to reveal their underlying structure.

Wittgenstein I: The Tractatus

Tractatus Logico-Philosophicus (1921/22) by Ludwig Wittgenstein (1889–1951) radicalizes Russell’s program.

Picture theory: A proposition is a picture of the world — it shares the same logical form as the state of affairs it represents. Elementary propositions represent atomic facts.

Limits of language: What can be said are the propositions of natural science — descriptions of how the world is. Questions of ethics, aesthetics, and metaphysics cannot be said; they show themselves (in the form of propositions, in the existence of the world). The famous final sentence (§7): whereof one cannot speak, thereof one must be silent.

Wittgenstein II: Philosophical Investigations

Philosophical Investigations (1953, posthumous) represents a radical turn. The later Wittgenstein abandons both the picture theory and the ideal of a perfect logical language.

Meaning as use: The meaning of a word is not the object it designates — it is its use in concrete linguistic practices. To ask for a meaning is to ask how a word is employed.

Language games (Sprachspiele): Language is not a unitary system but a family of diverse practices — commands, descriptions, questions, narratives, ceremonies. Each is a “game” with its own rules.

Rule-following: How does one know whether one has followed a rule correctly? No interpretation guarantees correct application — following a rule is participating in a practice, a form of life.

Private language argument: A genuinely private language (where names of sensations refer only to internal experience with no possibility of verification) is incoherent. Meaning requires public criteria of correctness.

J.L. Austin: Speech Acts

J.L. Austin (1911–1960) transformed philosophy by noting that language does not only describe the world.

Performatives vs. Constatives: Some utterances do not describe — they do. “I promise to return” does not describe a promise; it makes the promise. “I now pronounce you husband and wife” performs the marriage in being uttered.

Austin later recognized that the distinction is gradual and proposed the more general theory of speech acts (published posthumously in How to Do Things with Words, 1962):

  • Locutionary act: uttering sounds with sense and reference
  • Illocutionary act: what one does in uttering (promising, ordering, asserting, declaring)
  • Perlocutionary act: the effect produced on the hearer (convincing, intimidating, encouraging)

Grice: Conversational Implicature

Paul Grice (1913–1988) investigated how we communicate more than we say. The Cooperative Principle: participants in a conversation operate according to implicit maxims (quantity, quality, relation, manner). When a maxim appears to be violated, the hearer infers a conversational implicature — what the speaker meant beyond the literal utterance.

Kripke: Rigid Designators

Saul Kripke (1940–2022), in Naming and Necessity (1980), attacked the description theory as applied to proper names. Proper names are not abbreviated descriptions — they are rigid designators: they refer to the same object in all possible worlds. “Aristotle” names that specific individual — not the description “the teacher of Alexander the Great.”

A posteriori necessity: “Water is H₂O” is necessarily true (water could not be anything else in its essence), but it is an empirical discovery — refuting the Kantian equivalence of necessity and apriority.

The Legacy

Philosophy of language transformed all of philosophy: epistemology, metaphysics, ethics, and philosophy of mind all came to use linguistic analysis as a tool. The debate between semantics and pragmatics, between content and context, between reference and sense, remains alive in the twenty-first century.
