that started what is often called “the cognitive revolution” (Miller 2003), which he spearheaded with his critique of B.F. Skinner (Chomsky 1959). His work ensured that linguistic competence was viewed as part of cognition and, together with developments in psychology and philosophy, that mental computations over representations came to be seen as a legitimate and fertile area of research. In this section, we consider his legacy in two areas that we have labeled processing and acquisition.
Chapter 19 by Dave Kush and Brian Dillon explores how Chomsky's work has influenced research on one area of linguistic performance, namely sentence processing or “parsing.” In particular, they carefully demonstrate with examples how grammatical theory is relevant to such research: specifically, how the theory makes predictions about the behavior of the parser.
Work on parsing and linguistic perception focusses on real time processing of language, connecting syntax with psycholinguistics. A more recent development is research into the neurolinguistic underpinnings of language, which is the topic of Emiliano Zaccarella and Patrick C. Trettenbrein's Chapter 25. In particular, they are concerned with the neural signatures of the core components of grammar as put forward in much of Chomsky's work: universal principles of grammar, constituency, recursion, and Merge. The identification of such signatures supports Chomsky's claim that language is a biological system and that his work has significant implications for the study of the neuroscience of language.
Ever since Chomsky (1959), but in particular with Chomsky (1965), language acquisition has been a vital concern when developing theories that can model humans' linguistic abilities. This, in part, arises from Chomsky's conception of language as being essentially a biological phenomenon, where facts about growth and development are often essential to the characterization of its structure: a full theory of the structure of the eye needs to include an account of how it grows. Thus, for Chomsky, a central goal of linguistic theory has been what he calls “explanatory adequacy,” i.e., it must at least account for the possibility of language acquisition. And here a core argument has always been that children are born with the relevant constraints that determine the “hypothesis space” for acquiring the grammatical rules in a given language, what has traditionally been referred to as UG. In Chapter 21, Stephen Crain and Rosalind Thornton provide many examples of children's acquisition of restrictions on co‐reference that demonstrate the necessity of UG for any explanatory account of child language development.
Another area where Chomsky's ideas about innateness have been important is the linguistics of the spontaneous sign languages of the deaf. In Chapter, Diane Lillo‐Martin provides an overview of research on sign language grammar that has been inspired by Chomsky, focusing particularly on what that grammar can tell us about the innateness of linguistic abilities and cognitive modularity more generally.
The last area that this section surveys is work done on atypical acquisition. This encompasses two different types of cases: instances where there is no essential input during the early stages of acquisition, and instances where the stimulus is rich but insufficient due to some disorder. In Chapter 23 by Neil Smith and Ianthi Tsimpli, these cases are discussed in detail from the point of view of the influence of Chomsky's work. Smith and Tsimpli show that they provide invaluable evidence about the language faculty and its distinctness from and interaction with other aspects of human cognition.
1.6 Part V: Semantics, Pragmatics, and Philosophy of Language
Chomsky's work on grammar sees language as a bridge between sound and meaning, and has always aimed to explain certain facts about linguistic meaning. “Meaning,” of course, is a controversial and polysemous term, and the different entries in this section address some of the very different concerns to which it is attached.
One issue that has always been central to generative grammar is why certain readings of sentences are and others are not possible for certain sentences. For example, why can The man called the woman from Montana mean “The man called the woman, who was from Montana,” and “The man called, from Montana, the woman,” but not “The man, who was from Montana, called the woman”? And why are superficially very similar sentences understood so differently (John is easy to please entails It is easy to please John, but John is eager to please does not entail *It is eager to please John)? Equally, why do certain distinct strings have related or identical meanings (as with an active sentence and the related passive, for example)? Chomsky and other generativists provide answers in terms of underlying hierarchical sentence structures and constraints which explain both which structures can be generated and transformed, and how their constituents relate to each other: that is, by providing a syntactic theory. It is in this respect that generative syntax can be said to be essentially concerned with meaning.
Chomsky has, however, always opposed the widely held functionalist view of language according to which the purpose of language is communication, and the associated methodology that seeks to explain syntactic facts –which kinds of configurations of linguistic items are possible– in terms of semantic function, i.e., what they are used for. (Such views are discussed in Newmeyer's chapter in section 3.) Chomsky's view is that if language has any purpose at all, it is the expression of thought. He notes that many, indeed the vast majority of grammatical sentences, are hardly usable, because they are too long – e.g. example (2), or hard to parse (3), or combine words that are syntactically but not semantically compatible (4), for example:
1 (2) John and Mary and […+ two million conjuncts…] went to the party.
2 (3) Mice cats dogs chase bite squeak.
3 (4) Colorless green ideas sleep furiously.
Chomsky is, however, also skeptical about much work in linguistic semantics, in particular formal truth‐conditional semantics – at least if it is taken in full metaphysical seriousness, involving commitments to extralinguistic objects, as it often is in contemporary philosophy of language – since it treats word‐meanings as denotational (e.g. water denotes H2O, and London denotes the city of that name) and sentence meanings as involving truth conditions. Influenced on this point by the later Wittgenstein, JL Austin and Peter Strawson among others, he argues that it is language users who refer, not the words themselves considered in abstraction from use. Sentences should not be seen as contributing to meaningful propositions that are true or false by themselves independently of usage, but rather constraints on the thoughts that they can be used to express (when used literally).
In addition to these influences from ordinary language philosophers, and Chomsky's rejection of formal semantics, his conception of grammar as a system of computations over representations has been influenced by the formal, “analytic” tradition in the philosophy of language exemplified by the work of Frege, Russell, and the early Wittgenstein, as John Collins discusses in Chapter 24. Of course, for Chomsky the formal system is intended as a description of a particular aspect of cognition, the language faculty. Collins argues that it is a significant achievement of Chomsky's to propose that “language is its own thing, an object of interest regardless of its poor design relative to the ends to which formal systems are developed,” and to show how an explicit theory of that object can be provided.
Paul Pietroski's Chapter 25 explains in some detail the centrality to generative grammar of accounting for different readings in terms of underlying structures (discussed above). He also sets out some of the currents in modern philosophy of language that Chomsky opposes, in particular the truth‐conditional, referential conception of linguistic meaning found in the work of Donald Davidson and David Lewis, and Hilary Putnam's semantic externalism. He explains Chomsky's challenges to these views and shows how they point the way to an alternative, internalist conception of meaning.
