 No attempt has been made here to deal with one of the most difficult problems that meaning-theory includes—that of explaining how separate words, each one with its own meaning, can combine to yield sentence-meanings. It is feasible, perhaps, to take each word as having a disposition to affect cognition, just as the full sentence does. The problem reduces, then, to one of explaining the interplay of the dispositions of the several words, when realized conjointly. The analogy of the magnets will still serve, used now to illustrate the relationship of meanings rather than of beliefs. We may compare the meaning of each word with the disposition of some one of the magnets, and compare the meaning of the sentence with the disposition that may be assigned to the group of magnets. Each word has an independent meaning in the sense that if it is replaced by certain others in any context, there will be a typical sort of difference in the meaning of the context; but the precise way in which the word’s meaning is realized will depend on the meaning of the other words that accompany it.
