QUICK SUMMARY

The philosophy of language asks: How do words and sentences get their meaning? How does language connect to reality? Can thought exist without language? Is meaning determined by the speaker's intention, by social convention, or by the structure of the world? These questions dominated 20th-century analytic philosophy — the so-called "linguistic turn" — driven by the insight that many philosophical problems are actually problems about language. Gottlob Frege (1892) distinguished sense (the mode of presentation of a referent — how we think of something) from reference (the actual object referred to), solving the puzzle of why "the morning star = the evening star" is informative while "the morning star = the morning star" is trivial, even though both refer to Venus. Bertrand Russell (1905) argued that ordinary language is logically misleading — sentences like "The present king of France is bald" seem to be about an object but logically contain an existence claim that is false; proper logical analysis reveals the true form beneath surface grammar. Ludwig Wittgenstein offered two revolutionary philosophies of language: in the Tractatus Logico-Philosophicus (1921), language is a logical picture of reality — each meaningful proposition mirrors a possible state of affairs; in his later Philosophical Investigations (1953), he abandoned this picture theory entirely, arguing instead that meaning is use — words get their meaning from their role in language games (forms of life), not from correspondence to objects. J. L. Austin (1962) and John Searle (1969) developed speech act theory — language is not primarily about describing facts but about doing things: promising, ordering, apologizing, marrying, declaring. Saul Kripke (1980) argued that proper names are rigid designators — they refer to the same individual in all possible worlds, not via descriptions but via causal-historical chains; this has major implications for necessity, identity, and the mind-body problem. W. V. O. Quine (1960) challenged the analytic/synthetic distinction and argued for the indeterminacy of translation — there is no fact of the matter about what a speaker's words mean beyond behavioral dispositions.

1. THE LINGUISTIC TURN

1.1 The Centrality of Language to Philosophy

• The linguistic turn (Rorty's term, 1967): The dominant movement in 20th-century analytic philosophy — the idea that philosophical problems are fundamentally about language and can be solved (or dissolved) by analyzing the logical structure of language or the workings of ordinary language
• Motivated by failures of traditional metaphysics: instead of asking "What is truth?" or "What is justice?" directly, philosophers asked "What do we mean when we say something is true?" or "How does the word 'justice' function in discourse?"
• Two branches: (1) ideal language philosophy (Frege, Russell, early Wittgenstein, logical positivists) — construct a logically perfect language that eliminates philosophical confusion; (2) ordinary language philosophy (later Wittgenstein, Austin, Ryle, Strawson) — analyze how language actually works in everyday use; philosophical problems arise from "language going on holiday" (Wittgenstein)

2. FREGE — SENSE AND REFERENCE

2.1 The Morning Star Puzzle

• Gottlob Frege (1848–1925): "Über Sinn und Bedeutung" ("On Sense and Reference," 1892) — the founding text of philosophy of language
• The puzzle: "The morning star is the evening star" is an informative astronomical discovery (both are Venus); but "the morning star is the morning star" is trivially true; if meaning were just reference, the two sentences would mean the same thing (Venus = Venus); but they clearly don't
• Solution: Distinguish Sinn (sense — the mode of presentation, the way we think about the referent) from Bedeutung (reference — the actual object); "the morning star" and "the evening star" have the same reference (Venus) but different senses (different ways of identifying the same object)
• Compositionality: The meaning of a complex expression is determined by the meanings of its parts and the way they are combined — the principle of compositionality (attributed to Frege); this makes possible the productivity and systematicity of language

2.2 Frege's Legacy

• Frege also developed modern predicate logic (quantifiers, variables, functions) — the most important advance in logic since Aristotle; this formal apparatus became the tool for analyzing the logical structure of natural language
• His work influenced virtually every major figure in analytic philosophy of language: Russell, Wittgenstein, Carnap, Quine, Davidson, Dummett

3. RUSSELL — LOGICAL ATOMISM AND DEFINITE DESCRIPTIONS

3.1 The Theory of Descriptions

• "On Denoting" (1905): Russell's most famous paper; addresses sentences containing definite descriptions like "the present king of France"
• Problem: "The present king of France is bald" — there is no present king of France; is the sentence true? False? Meaningless?
• Russell's analysis: the sentence is NOT simply about an object "the present king of France"; it actually asserts three things: (1) there exists something that is the present king of France, (2) there is only one such thing, and (3) that thing is bald; since (1) is false, the whole statement is false — not meaningless
• Philosophical significance: ordinary language is logically misleading — the grammatical subject "the present king of France" appears to name an object but doesn't; proper logical analysis reveals hidden logical structure; this inspired the entire project of using formal logic to analyze natural language

3.2 Logical Atomism

• Russell and early Wittgenstein developed logical atomism — the view that the world consists of logical "atoms" (simple facts) that correspond to logical atoms of language (elementary propositions); complex propositions are truth-functions of elementary propositions; the structure of language mirrors the structure of reality

4. EARLY WITTGENSTEIN — THE TRACTATUS

4.1 The Picture Theory

• Tractatus Logico-Philosophicus (1921): Language represents reality by picturing it — a proposition is a logical picture of a possible state of affairs; the elements of the proposition correspond to elements of reality, and the arrangement of elements in the proposition mirrors the arrangement of elements in the world
• What can be said: Only propositions that picture possible facts are meaningful; factual discourse (science) is meaningful; the rest — ethics, aesthetics, metaphysics, the meaning of life — cannot be said but only "shown"
• "Whereof one cannot speak, thereof one must be silent" (Tractatus 7) — the famous final proposition; Wittgenstein believed he had dissolved all philosophical problems by showing they arise from misunderstanding the logic of language

4.2 Logical Positivism's Appropriation

• The Vienna Circle (Carnap, Schlick, Neurath) adopted the Tractatus as foundation for logical positivism: the verification principle — a statement is meaningful only if it can be verified empirically or is a tautology of logic/mathematics; metaphysical, ethical, and theological statements are literally meaningless
• Wittgenstein himself was uncomfortable with this appropriation; he regarded the Tractatus as having mystical dimensions the positivists ignored

5. LATER WITTGENSTEIN — LANGUAGE GAMES

5.1 The Philosophical Investigations

• Philosophical Investigations (1953, published posthumously): Wittgenstein's radical self-critique — he repudiated the Tractatus's picture theory and offered a completely different account of language
• Meaning is use: "For a large class of cases — though not for all — in which we employ the word 'meaning' it can be defined thus: the meaning of a word is its use in the language" (§43); meaning is not a mental image, not a Platonic entity, not a correspondence to an object — it is the way a word functions in a form of life
• Language games: Language is a collection of overlapping, family-resemblance-related activities — naming, describing, requesting, commanding, joking, praying, greeting, cursing, etc.; each has its own rules, purposes, and contexts; there is no single essence of "language" — just a family of related activities
• Family resemblance: Concepts like "game" do not have a single defining feature shared by all instances; instead, different games share overlapping similarities (competition, rules, amusement, physical activity) without any one feature being common to all — a network of similarities, like family resemblances

5.2 The Private Language Argument

• One of the most debated arguments in 20th-century philosophy (§§243–315): Can there be a language that only one person can understand — a language referring to private inner sensations (e.g., "S" for a particular sensation I feel)?
• Wittgenstein argued: No — language requires rules, and rules require a distinction between following a rule correctly and merely thinking you are following it; in a purely private case, there is no such distinction — "whatever is going to seem right to me is right. And that only means that here we can't talk about 'right'" (§258)
• Implication: the meaning of sensation-words ("pain," "red") is not determined by private ostensive definition (pointing inward) but by public criteria — behavioral expressions, contexts of use, communal practices; this challenges Cartesian privacy and has implications for the philosophy of mind

6. SPEECH ACT THEORY — AUSTIN AND SEARLE

6.1 J. L. Austin — How to Do Things with Words

• How to Do Things with Words (1962, posthumous): Austin noted that many utterances are not descriptions of facts (statements that are true or false) but performative actions: "I promise to pay you back" (makes a promise), "I name this ship the Queen Elizabeth" (performs a naming), "I find the defendant guilty" (delivers a verdict); these are neither true nor false — they are felicitous or infelicitous (successful or unsuccessful as acts)
• Three dimensions of speech acts: (1) Locutionary act — the utterance itself (saying certain words with certain meanings); (2) Illocutionary act — what you are doing in saying those words (asserting, promising, commanding, apologizing); (3) Perlocutionary act — the effect of the act on the hearer (persuading, alarming, amusing)
• Austin eventually argued that ALL utterances involve illocutionary force — even statements ("It is raining") are not just descriptions but acts of asserting

6.2 John Searle — Speech Acts and Intentionality

• Speech Acts (1969): Systematized Austin's framework; classified illocutionary acts into five types: assertives (stating facts), directives (requests, commands), commissives (promises), expressives (apologies, congratulations), and declaratives (pronouncements that change social reality)
• Constitutive rules: Some speech acts create new social facts: "I declare you husband and wife" (creates a marriage); these are constitutive rules — not regulations of pre-existing activities but creators of new institutional realities; this influenced Searle's later work on social ontology (The Construction of Social Reality, 1995)

7. KRIPKE — NAMING AND NECESSITY

7.1 Rigid Designators and the Causal Theory

• Naming and Necessity (1980): Kripke challenged the descriptivist theory of names (Frege/Russell) — that names have meaning via associated descriptions ("Aristotle" means "the teacher of Alexander" or "the author of the Metaphysics"); Kripke argued that names are rigid designators — they refer to the same individual in all possible worlds
• The causal-historical theory: A name refers to its bearer not via descriptions but via a causal chain of reference-transmissions going back to an initial "baptism" (naming event); I use "Aristotle" to refer to Aristotle because my use is causally connected to a chain of speakers going back to the original naming
• Necessary a posteriori truths: "Hesperus is Phosphorus" (= "the evening star is the morning star") is necessarily true (both rigidly designate Venus in all possible worlds) but knowable only a posteriori (by astronomical discovery) — challenging the traditional equation of necessary truths with a priori truths
• Implications for mind-body identity: If "pain = C-fiber firing" is an identity, it must be necessary (like "water = H₂O"); but it seems conceivable that pain could exist without C-fibers → this conceivability suggests pain ≠ C-fibers; Kripke thus provides an argument against physicalist identity theory — deeply connected to the zombie argument (K_1_09)

8. QUINE, DAVIDSON, AND GRICE

8.1 Quine — Indeterminacy and Holism

• "Two Dogmas of Empiricism" (1951): Attacked the analytic/synthetic distinction (analytic = true by virtue of meaning; synthetic = true by virtue of fact); argued that no sharp line separates them — all beliefs face the "tribunal of experience" as a whole (holism); revision of any belief can be compensated by adjustments elsewhere in the web
• Indeterminacy of translation: In Word and Object (1960), Quine argued that there is no fact of the matter about what a speaker's words mean beyond behavioral dispositions; multiple incompatible translation manuals could fit the same speech behavior equally well; meaning is not a determinate property

8.2 Davidson — Truth-Conditional Semantics

• Donald Davidson (Inquiries into Truth and Interpretation, 1984): The meaning of a sentence is given by its truth conditions — to understand a sentence is to know what the world would have to be like for it to be true; this connects meaning to Tarski's formal theory of truth; Davidson also developed the principle of charity — in interpreting others, we must assume they are largely rational and largely right

8.3 Grice — Meaning and Implicature

• H. P. Grice ("Meaning," 1957; "Logic and Conversation," 1975): Distinguished between natural meaning (smoke means fire) and non-natural meaning (speaker-meaning); speaker-meaning involves the intention to produce a response in the hearer by means of the hearer's recognition of that intention
• Conversational implicature: Speakers communicate more than they literally say — "Can you pass the salt?" literally asks about ability but implicates a request; Grice's cooperative principle and its maxims (quantity, quality, relation, manner) explain how hearers infer what speakers mean beyond the literal content

9. COUNTER-ARGUMENTS AND CRITICAL ASSESSMENT

9.1 Limits of the Linguistic Turn

• Critics argue that the linguistic turn overemphasizes language at the expense of direct engagement with metaphysical, ethical, and experiential questions; some philosophers (e.g., Heidegger, Merleau-Ponty) insist that lived experience, embodiment, and being-in-the-world precede and exceed linguistic articulation

9.2 Internalism vs. Externalism

• A major debate: Is meaning "in the head" (determined by the speaker's internal mental states) or "in the world" (determined by the external environment)? Putnam's Twin Earth thought experiment (1975) and Burge's anti-individualism (1979) argue for externalism — meaning depends on the external environment and social community, not just individual psychology

9.3 Language and Thought

• Can there be thought without language? Strong versions of the Sapir-Whorf hypothesis (linguistic determinism — language determines thought) are largely rejected; weak versions (linguistic relativity — language influences thought) are supported by empirical evidence; animals, pre-linguistic infants, and aphasic patients show evidence of non-linguistic thought
