Abstract

This chapter argues against Chomsky’s view that linguistics is a branch of psychology, and hence concerns a psychological reality: the speaker’s linguistic competence. With the help of three quite general distinctions, including that between structure rules and processing rules, and between being a structure rule and “respecting” one, it is argued that there is something other than psychological reality for a grammar to be true of: it can be true of a linguistic reality. Given the weight of evidence, it is plausible that the grammar is indeed more or less true of that reality. The grammar might also be true of a psychological reality, but to show that it is so requires further psychological assumption. It will prove hard to establish a psychological assumption that will do the trick.
