This site has, by now, nine features on nine thinkers (one of them a pair) — Plato, Aristotle, Arnauld and Lancelot at Port-Royal, Humboldt, Saussure, Sapir, Wittgenstein, Chomsky, and Austin. Each was read on its own, close to its original text.

Line the nine up together, though, and one question turns out to have stayed alive the whole time, changing its clothes as it goes. Is language a finished “thing,” or an activity still in progress? Is a name, or a sentence, correct because nature made it so, or because people agreed to it? This feature runs across the other nine, retelling that one question’s history in seven chapters. The close reading of each thinker already exists in their own feature; here the focus is on the space between them — what got carried forward, and what got overturned.

One question, running through twenty-three centuries

Laid out on a timeline, the sheer span is the first surprise. Plato’s Cratylus is fourth century BC; Austin’s How to Do Things with Words is 1962 — roughly 2,300 years apart.

4th c. BC Plato 4th c. BC Aristotle 1660 Port-Royal 1836 Humboldt 1916 Saussure 1921 Sapir 1921 / 1953 Wittgenstein 1957 Chomsky 1962 Austin Spacing is compressed for legibility, not proportional to real intervals — the gap between Aristotle and Port-Royal alone is about 1,900 years.

Across 2,300 years, of course, the languages spoken and the tools of scholarship both changed beyond recognition. And yet the shape of the question running through these nine is remarkably stable. What Plato called “the correctness of names” (onomatos orthotēs) becomes, in Aristotle, “a symbol by convention” (symbolon kata synthēkēn); in Port-Royal, “does grammar mirror the mind?”; in Humboldt, “is language a product or an activity?”; in Saussure, “what is a system?”; in Wittgenstein, “what is meaning?”; in Austin, “is saying already doing?” The names change. The root question doesn’t.

A second axis — language as thing, language as activity

Dates alone don’t explain why thought moved the way it did. So lay a second axis across the timeline: does a thinker treat language as a fixed structure or entity, or as an ongoing activity or act?

Language as structure or entity a finished, fixed system (ergon) Language as activity or act a living activity still under way (energeia) Aristotle — the conventional symbol Port-Royal — a mirror of reason Saussure — a system of differences Chomsky — an innate syntactic device Humboldt — energeia Sapir — a cultural pattern Late Wittgenstein — language games Austin — the performative Early Wittgenstein (picture theory) → late (language games)
"Structure or entity" versus "activity or act" — the second axis dividing these nine thinkers. Diagram: ToL

On the left sit those who treat language as an already-finished mechanism. Aristotle defines the word as “a symbol by convention” and then catalogues exactly where truth and falsity can live (only in the statement) — language, here, is fixed as an object of analysis. Port-Royal finds one rational grammar behind every language and paints grammar as a mirror of the mind’s operations. Saussure cuts langue loose from any individual’s will and treats it as a system made of nothing but differences. Chomsky treats grammar as a device innately built into the mind — autonomous from both meaning and frequency of use.

On the right sit those who treat language as a living activity, still under way. Humboldt states outright that language is not a “product” (ergon) but a “working” (energeia), and locates its essence in the act of speaking itself. Sapir describes language as neither instinct nor race, but a cultural pattern a community carries. The later Wittgenstein finds a word’s meaning not in some dictionary referent but in its use in the course of life. Austin pushes that a step further, showing that some sentences — performatives — don’t just describe an act, they are one.

And one thinker crossed this axis in a single lifetime: Wittgenstein himself. In the early Tractatus, a proposition is a picture of reality — close to the structural camp, alongside Aristotle and Saussure. In the later Philosophical Investigations, he dismantles that view himself and crosses to the other side: “meaning is use.” The whole pendulum this feature traces across nine thinkers appears, in miniature, inside one philosopher’s own career.

Seven chapters

From here, the story runs chronologically across seven chapters. Each stands on its own, but read in order they trace how one question kept changing shape while staying, underneath, the same question.

  1. The Question Is Born — Plato and Aristotle
  2. Grammar Mirrors the Mind — the Port-Royal Wager
  3. Language Is an Activity — Humboldt’s Turn
  4. Toward a System of Differences — Saussure and the Independence of Linguistics
  5. Neither Instinct nor Race — Sapir and Plural Worldviews
  6. From Picture to Use to Act — Wittgenstein, Chomsky, Austin

Summary

Thinker (work, year)Language isStructure or activity?
Plato (Cratylus, 4th c. BC)Whether a name’s correctness is natural or conventional — left open, resolved into a theory of naming as a tool(the question is born)
Aristotle (De Interpretatione, 4th c. BC)A symbol by convention; truth and falsity live only in the statementStructure
Port-Royal (Grammaire générale, 1660)A universal grammar mirroring the mind’s operations, behind every languageStructure
Humboldt (1836)Not a “product” but a “working” — an activity that shapes a worldviewActivity
Saussure (Course, 1916)A synchronic system made of nothing but differencesStructure
Sapir (Language, 1921)Neither instinct nor race, but a cultural patternLeans activity

Austin (How to Do Things with Words, 1962)Saying is, in many cases, already doing (the performative)Activity

In a nutshell — there is still no final answer to “what is language.” But over 2,300 years, thought hasn’t moved at random either. A pull toward fixing language as a “thing,” and a pull toward releasing it as a “working,” keep showing up in turn, like a pendulum. Whatever answer comes next will likely swing from one side of that same arc.
