Infinite Use of Finite Means — the Source of Generative Grammar

Energeia saw language as “an act, not a thing.” What that act concretely achieves — one of Humboldt’s answers is this short phrase.

1. “Infinite use of finite means”

Sie muss daher von endlichen Mitteln einen unendlichen Gebrauch machen, und vermag dies durch die Identität der Gedanken und Sprache erzeugenden Kraft.

It must therefore make infinite use of finite means, and can do so through the identity of the power that generates thought and language. (German quotations throughout; Japanese and English are L/LAB working translations.)

A language is not a collection (Sammlung) of words but a generation (Erzeugung). A speaker does not pull a memorised sentence from storage but builds one, each time, with rules. And because a rule can be nested inside a rule (“the cat is asleep” → “I think [the cat is asleep]”), there is in principle no upper bound on length. From a finite toolkit, an infinite output.

2. Why it is possible — thought and language are the same power

Humboldt puts the reason in “the identity of the power that generates thought and language.” The capacity to build a sentence is not something apart from the capacity to compose a thought. So a speaker can say a thought met for the first time in a sentence made for the first time. This picture of “language = a generating power” is the concretising of the “genetic definition” from energeia, and continuous with Humboldt’s calling “form (Form)” not a set of facts but a procedure (Verfahren).

3. The phrase Chomsky raised

The generative grammar Noam Chomsky set out in Syntactic Structures (1957) and Aspects of the Theory of Syntax (1965) puts at the centre of language “the speaker’s internal system that generates an unbounded set of sentences from finite rules.” The next year, in Cartesian Linguistics (1966), Chomsky traced this idea back through Descartes and the Port-Royal grammar to Humboldt. The central notion is “the creative aspect of language use” — our utterances are unbounded in number, not controlled by stimuli, and yet appropriate to the situation.

But this reading is selective. What Chomsky foregrounded was Humboldt’s “generating power” and the “universal” side. Humboldt’s actual subject — the diversity of languages — and the Romantic side, worldview and “the spirit of a people,” were pushed to the background. The same Humboldt is cited by relativists as the ancestor of “diversity” and by generativists as the ancestor of “universal generative power.”

In sum

Humboldt’s claim	twentieth-century reception
Language makes infinite use of finite means	Chomsky cites it as the motto of generative grammar
The power that generates thought and language is one	“competence” = a generative system in the mind
Form is not a set of facts but a procedure	a forerunner of “generative rules”
The book’s subject is the “diversity” of languages	Chomsky inherits “universal”; relativists inherit “diversity”

Why it is still read

• The official ancestor of generative grammar — “infinite use of finite means” is the line linguistics textbooks quote when they reach for Humboldt.
• The problem of creativity — how to explain “stimulus-free, situationally appropriate, unbounded utterance” is still a central question for linguistic theory and cognitive science.
• One thinker, two lineages — that Humboldt is a source of both relativism and universalism shows that the twentieth century’s two great currents in linguistics share a root.
