Why Compositionality Won’t Go Away: Reflections on Horwich ’s ‘Deflationary’ Theory

Abstract

Abstract COMPOSITIONALITY is the idea that the meanings of complex expressions (or concepts) are constructed from the meanings of the less complex expressions (or concepts) that are their constituents. Over the last few years, we have just about convinced ourselves that compositionality is the sovereign test for theories of lexical meaning. So hard is this test to pass, we think, that it filters out practically all of the theories of lexical meaning that are current in either philosophy or cognitive science. Among the casualties are, for example, the theory that lexical meanings are statistical structures (like stereotypes); the theory that the meaning of a word is its use; the theory that knowing the meaning of (at least some) words requires having a recognitional capacity for (at least some) of the things that it applies to; and the theory that knowing the meaning of a word requires knowing criteria for applying it.
