What you will get from this article
- What The Language Instinct claims, in one sentence
- What kinds of evidence support the claim
- What each of the eight articles in this series covers, and what it leaves out
The answer first. Steven Pinker argues that language is not a cultural invention but a biological ability built into the human brain: an instinct. Spiders spin webs without being taught; human children acquire grammar without being taught. Seen that way, three puzzles fall into one story: why children come to speak, why their grammatical errors are not just imitation of parents, and why some illnesses damage language alone.
In one sentence
Early in the book (p. 18) Pinker states his claim.
Language is not a cultural artifact that we learn the way we learn to tell time or how the federal government works. Instead, it is a distinct piece of the biological makeup of our brains.
The word “instinct” is chosen on purpose. Pinker says one could call language a “mental organ” or a “computational module,” but “instinct” best conveys that people know how to talk in the sense that spiders know how to spin webs (p. 18).
Who the book is for
In the preface the author lists readers (language lovers, popular-science readers, students, professional colleagues, general nonfiction readers) and what he promises each (pp. 7–8). In short, it is not a book about etymology or correct usage; it is a book about the mental machinery that makes language possible (cognitive science).
Four kinds of evidence
Chapters 1–2 line up evidence for “language is an instinct” in order (ToL’s sorting).
| Evidence | Content | Article |
|---|---|---|
| 1. Universality | Even Stone Age societies have complex grammar | 294 |
| 2. Children remake language | Pidgins become creoles; Nicaraguan Sign Language arises | 295 |
| 3. Knowing what was never taught | Forming questions, the “-s” agreement | 296 |
| 4. Brain and genes | Language alone breaks, or language alone survives | 297 |
Chapter 3 rejects the common-sense view that language determines thought (articles 298 and 299). Chapter 4 explains how language actually works, namely that grammar is a tree structure (article 300).
Relation to Chomsky
Pinker is deeply influenced by Chomsky. In chapter 1 he introduces Chomsky’s two points: nearly every sentence is a new combination of words, and children acquire a complex grammar without instruction (p. 22).
But Pinker says the story is “not his story exactly.” The difference is mainly in evolution: Pinker finds it fruitful to treat language as an evolutionary adaptation, like the eye, and contrasts this with Chomsky’s skepticism (p. 24). That issue later became the Pinker–Bloom paper, treated in another article alongside Scott-Phillips’s critical reading (Is language an adaptation?).
Cautions
- This is a summary of Pinker’s claims, not a consensus of the field. Innateness is still debated.
- Experiments and figures follow the book’s account; I have not checked the original papers.
- The scope of this series is the preface and chapters 1–4 (pp. 7–106). Chapter 5 onward (words, sounds, the brain, language change, details of child acquisition, evolution, language mavens, mind design) is not covered.
