Thesis

Pinker sets out to disabuse the reader of a number of common ideas about language, e.g. that children must be taught to use it, that most people's grammar
Grammar
In linguistics, grammar is the set of structural rules that govern the composition of clauses, phrases, and words in any given natural language. The term refers also to the study of such rules, and this field includes morphology, syntax, and phonology, often complemented by phonetics, semantics,...

). Each of these claims, he argues, is false. Instead, Pinker sees language as an ability unique to humans, produced by evolution

s with true grammar rather than a crude "me Tarzan, you Jane" pointing system. Language (speech) also develops in the absence of formal instruction or active attempts by parents to correct children's grammar. These signs suggest that rather than being a human invention, language is an innate human ability. Pinker also distinguishes language from humans' general reasoning ability, emphasizing that it is not simply a mark of advanced intelligence but rather a specialized "mental module". He distinguishes the linguist's notion of grammar, such as the placement of adjectives, from formal rules such as those in the American English

, which focus on clarity of expression rather than prescriptive rules of grammar.

Pinker attempts to trace the outlines of the language instinct by citing his own studies of language acquisition in children, and the works of many other linguists and psychologists in multiple fields, as well as numerous examples from popular culture. He notes, for instance, that specific types of brain damage cause specific impairments of language such as Broca's aphasia or Wernicke's aphasia, that specific types of grammatical construction are especially hard to understand, and that there seems to be a critical period

 in childhood for language development just as there is a critical period for vision development in cats. Much of the book refers to Chomsky's concept of a universal grammar, a meta-grammar into which all human languages fit. Pinker explains that a universal grammar represents specific structures in the human brain that recognize the general rules of other humans' speech, such as whether the local language places adjectives before or after nouns, and begin a specialized and very rapid learning process not explainable as reasoning from first principles

 or pure logic. This learning machinery exists only during a specific critical period of childhood and is then disassembled for thrift, freeing resources in an energy-hungry brain.

Implications

The implications of the language-instinct hypothesis are far-reaching. Language and similar abilities are some of the traits that most clearly set humans apart from other animals, and have been claimed by thinkers such as Alfred Russel Wallace

, has been dedicated mostly to the critique of Pinker's work. The notion of the brain/mind as a set of modules with irreplaceably distinct functions, including linguistic functions, is said to be disproved by recoveries after stroke and surgical brain hemisphere removal. A TV show "Evolve" claimed for the thesis of a uniquely human language module in the brain to be disproved with brain scans of chattering chimpanzees, which supposedly showed the same pattern of brain activity as talking humans.

The statement that deaf babies "spontaneously invent sign languages with complex grammar" is actually only true in groups of deaf children (deaf communities) while a lone deaf child in a village where everyone else can hear never invents more than simple gestures.
