Concept
Generative semantics
Summary
Generative semantics was a research program in theoretical linguistics which held that syntactic structures are computed on the basis of meanings rather than the other way around. Generative semantics developed out of transformational generative grammar in the mid-1960s, but stood in opposition to it. The period in which the two research programs coexisted was marked by intense and often personal clashes now known as the linguistics wars. Its proponents included Haj Ross, Paul Postal, James McCawley, and George Lakoff, who dubbed themselves "The Four Horsemen of the Apocalypse".
Generative semantics is no longer practiced under that name, though many of its central ideas have blossomed in the cognitive linguistics tradition. It is also regarded as a key part of the intellectual heritage of head-driven phrase structure grammar (HPSG) and construction grammar, and some of its insights live on in mainstream generative grammar. Pieter Seuren has developed a semantic syntax which is very close in spirit to the original generative semantics framework, which he played a role in developing.
The controversy surrounding generative semantics stemmed in part from the competition between two fundamentally different approaches to semantics within transformational generative syntax. In the 1960s, work in the generative tradition assumed that semantics was interpretive in the sense that the meaning of a sentence was computed on the basis of its syntactic structure rather than the other way around. In these approaches, syntactic structures were generated by rules stated in terms of syntactic structure alone, with no reference to meaning. Once generated, these structures would serve as the input to a semantic computation which would output a denotation. This approach captured the relationship between syntactic and semantic patterns, while allowing the syntax to work independently of the semantics, as Chomsky and others had argued for on the basis of empirical observations such as the famous "colorless green ideas sleep furiously" sentence.
