 But in other theories of meaning, the order of metaphysical determination is reversed. Consider, for instance, a theory in which word meaning is derived from patterns of usage—a theory, for instance, in which the word ‘cha-cha’ derives its meaning at a time from uses of that word up to that time. Or consider a descriptive theory of meaning—a theory in which the word ‘cha-cha’ derives its meaning from the cluster of descriptions that the English-speaking community associates with it. If we add to these theories of linguistic meaning the further claim that social categories are identified with semantic values, then it is linguistic building blocks that set up the social kind cha-cha.
