Notion of generalization commitments

The first key commitment is the Generalization Commitment (Lakoff, 1990). It represents a dedication to characterizing general principles that apply to all aspects of human language. This goal is just a special subcase of the standard commitment in science to seek the broadest generalizations possible. In contrast to the cognitive linguistics approach, other approaches to the study of language often separate the language faculty into distinct areas such as phonology (sound), semantics (word and sentence meaning), pragmatics (meaning in discourse context), morphology (word structure), syntax (sentence structure), and so on. As a consequence, there is often little basis for generalization across these aspects of language, or for study of their interrelations. This is particularly true of formal linguistics. Formal linguistics attempts to model language by positing explicit mechanical devices or procedures operating on theoretical primitives in order to produce all the possible grammatical sentences of a given language. Such approaches typically attempt precise formulations by adopting formalisms inspired by computer science, mathematics and logic. Formal linguistics is embodied most notably by the work of Noam Chomsky (e.g., 1965, 1981, 1995) and the paradigm of Generative Grammar, as well as the tradition known as Formal Semantics, inspired by philosopher of language Richard Montague (1970, 1973; see Cann, 1993, for a review). Within formal linguistics it is usually argued that areas such as phonology, semantics and syntax concern significantly different kinds of structuring principles operating over different kinds of primitives. For instance, a syntax ‘module’ is an area in the mind concerned with structuring words into sentences, whereas a phonology ‘module’ is concerned with structuring sounds into patterns permitted by the rules of any given language, and by human language in general. This modular view of mind reinforces the idea that modern linguistics is justified in separating the study of language into distinct sub-disciplines, not only on grounds of practicality, but because the components of language are wholly distinct, and, in terms of organization, incommensurable. Cognitive linguists acknowledge that it may often be useful to treat areas such as syntax, semantics and phonology as being notionally distinct. However, given the Generalization Commitment, cognitive linguists do not start with the assumption that the ‘modules’ or ‘subsystems’ of language are organized in significantly divergent ways, or indeed that wholly distinct modules even exist. Thus, the Generalization Commitment represents a commitment to openly investigating how the various aspects of linguistic knowledge emerge from a common set of human cognitive abilities upon which they draw, rather than assuming that they are produced in encapsulated modules of the mind. The Generalization Commitment has concrete consequences for studies of language. First, cognitive linguistic studies focus on what is common among aspects of language, seeking to re-use successful methods and explanations across these aspects. For instance, just as word meaning displays prototype effects – there are better and worse examples of referents of given words, related in particular ways – so various studies have applied the same principles to the organization of morphology (e.g., Taylor, 2003), syntax (e.g., Goldberg, 1995), and phonology (e.g., Jaeger & Ohala, 1984). Generalizing successful explanations across domains of language isn’t just a good scientific practice – it is also the way biology works; reusing existing structures for new purposes, both on evolutionary and developmental timescales. Second, cognitive linguistic approaches often take a ‘vertical’, rather than a ‘horizontal’ approach to the study of language. Language can be seen as composed of a set of distinct layers of organization – the sound structure, the set of words composed by these sounds, the syntactic structures these words are constitutive of, and so on. If we array these layers one on top of the next as they unroll over time (like layers of a cake), then modular approaches are horizontal, in the sense that they take one layer and study it internally – just as a horizontal slice of cake. Vertical approaches get a richer view of language by taking a vertical slice of language, which includes phonology, morphology, syntax, and of course a healthy dollop of semantics on top. A vertical slice of language is necessarily more complex in some ways than a horizontal one – it is more varied and textured – but at the same time it affords possible explanations that are simply unavailable from a horizontal, modular perspective.
