Cognitive linguists deny that the mind has any module for language-acquisition that is unique and autonomous. This stands in contrast to the stance adopted by Noam Chomsky and others in the field of generative grammar . Although cognitive linguists do not necessarily deny that part of the human linguistic ability is innate, they deny that it is separate from the rest of cognition. They thus reject a body of opinion in cognitive science suggesting that there is evidence for the modularity of language. Departing from the tradition of truth-conditional semantics , cognitive linguists view meaning in terms of conceptualization. Instead of viewing meaning in terms of models of the world, they view it in terms of mental spaces .
