Is Chomsky's Theory of Language Wrong? Pinker Weighs in on Debate

Critics have bashed linguist Noam Chomsky for more than 50 years, but his claim that language is innate endures

Asked for a comment on the language-acquisition theory of Noam Chomsky (in photo above), psychologist Steven Pinker says: “Chomsky has been a piñata, where anyone who finds some evidence that some aspect of language is learned (and there are plenty), or some grammatical phenomenon varies from language to language, claims to have slain the king. It has not been a scientifically productive debate, unfortunately.”

Noam Chomsky’s political views attract so much attention that it’s easy to forget he’s a scientist, one of the most influential who ever lived. Beginning in the 1950s, Chomsky contended that all humans possess an innate capacity for language, activated in infancy by minimal environmental stimuli. He has elaborated and revised his theory of language acquisition ever since.

Chomsky’s ideas have profoundly affected linguistics and mind-science in general. Critics attacked his theories from the get-go and are still attacking, paradoxically demonstrating his enduring dominance. Some attacks are silly. For example, in his new book A Kingdom of Speech Tom Wolfe asserts that both Darwin and “Noam Charisma” were wrong. (See journalist Charles Mann’s evisceration of Wolfe.)

Other critiques are serious. In “Language in a New Key,” in the November Scientific American, Paul Ibbotson and Michael Tomasello contend that “much of Noam Chomsky’s revolution in linguistics, including its account of the way we learn languages, is being overturned.” The online headline says “Evidence Rebuts Chomsky's Theory of Language Learning.” Ibbotson and Tomasello propose that children acquire language via “general cognitive abilities and the reading of other people’s intentions.”

Seeking enlightenment, I asked psychologist Steven Pinker what he thinks about the recent criticism of Chomsky. Pinker has written several acclaimed books on language, notably The Language Instinct (1994) and The Stuff of Thought (2007). In his emailed response, Pinker defends Chomsky, sort of. None of Chomsky’s critics have created a language-acquisition model that entirely dispenses with “innate structure,” Pinker contends. Here are his comments in full:

None of this is new—the same debate has been playing out for fifty years. Contrary to the claim that Chomsky’s theories are an orthodoxy, dominant approach, or consensus (which makes any challenger into a giant-slayer), they have never been anything close to the default in the sciences of language. I’d say that perhaps Chomsky’s theory (at any time) has attracted a plurality of linguists, but probably never a majority, since there have always been rival theories (Generative Semantics, Cognitive Grammar, Relational Grammar, Lexical Functional Grammar, Generalized Phrase Structure Grammar, and, perhaps for most, just no commitment to any overarching theory at all). In other fields, Chomsky’s theories were only ever embraced by a small minority, and the opposition has always been fierce: from philosophers like Putnam, Goodman, Searle, and Dennett in the 1960s and 1970s; from Jerome Bruner and Piagetian developmental psychologists in the 1970s; from Good Old-Fashioned AI researchers like Terry Winograd, Roger Schanck, and Marvin Minsky in the 1970s; from the connectionist psychologists and neural-network AI researchers in the 1980s; from “dynamic systems theorists” like Linda Smith in 1980s; probably from most child language acquisition researchers in every decade.

The misconception that Chomsky represents the dominant view comes from the fact that the opposition is divided into many approaches and factions, so there’s no single figure that can be identified with an alternative. Also, he’s famous and charismatic, and people outside the field have heard of him, but haven’t heard of anyone else, and confuse his fame with professional dominance.

Another problem with the claim that Chomsky’s theory of language “is being overturned” (as if it had ever been accepted, which is not true), is that it’s not clear what “Chomsky’s theory of language” refers to. He has proposed a succession of technical theories in syntax, and at the same time has made decades of informal remarks about language being innate, which have changed over the decades, and have never been precise enough to confirm or disconfirm. And it’s not so easy to say what “Universal Grammar” or an innate “language faculty” consists of; it’s necessarily abstract, since the details of any particular language, like Japanese or English, are uncontroversially learned. So for 50 years Chomsky has been a piñata, where anyone who finds some evidence that some aspect of language is learned (and there are plenty), or some grammatical phenomenon varies from language to language, claims to have slain the king. It has not been a scientifically productive debate, unfortunately.

My own view is that we need to create precise computational models of the language acquisition process – sentences in, grammar out – and see if they succeed in mastering the structure of any language whose sentences are fed into it, in a way that resembles the way children do it. Then whatever is in that model is the best theory of the child’s innate learning abilities. Every now and again someone will try to do that (I did in my first book, Language Learnability and Language Development, in 1984.) Failing that, it’s all too easy to claim that children don’t need any innate priors or assumptions or representations, only to sneak them back in when it comes to get serious and implement a model. That was the trick in a lot of the neural-network models of language that were popular in the 80s and 90s – when the rubber met the road, they always built in innate structure without calling attention to it. That’s what I suspect will be true of models based on the current ideas. –Steven Pinker

If I may paraphrase: Pinker is saying that Chomsky’s fundamental claim--that language is innate—will endure in one form or another. Chomsky himself recently dismissed criticism of his innate-language theory, telling The New York Times that Tom Wolfe’s attack “hardly rises to the level of meeting a laugh test.”

More than 20 years ago, I asked Chomsky which work he preferred, political activism or linguistic research. The question surprised him. He said he protested injustice out of a sense of duty, not intellectual pleasure. He would happily give science his full attention if the world's problems vanished. [See my profile of Chomsky based on that 1990 interview.] 

Our problems persist, and so does Chomsky. In this post-election interview, he says that Donald Trump and the Republican Party, by rejecting restrictions on fossil-fuel consumption, are “racing as rapidly as possible to destruction of organized human life.” The linguist does not mince words.

Steven Pinker tipped me off to this splendidly scathing review in 3.A.M. Magazine by E.J. Spode of Tom Wolfe’s silly book about Chomsky and Darwin. E.J. Spode may be a pseudonym, although I can't imagine why he wouldn't want to take credit for this masterpiece of informed invective.
