 Identity theorists are agreed that, in the case of any particular relevant identity, a fact will constitute the worldly relatum of the relation, but there is significant disagreement among them on the question what the item on the other end of the relation is—whether a thought or a proposition (or both). As we have seen, there are three possible positions here: (i) one which places the identity relation exclusively between true thoughts and facts, (ii) one which places it exclusively between true propositions and facts, and (iii) a hybrid position which allows identities of both sorts (identities obtaining at the level of sense will of course be quite distinct from identities obtaining at the level of reference). Which of these positions an identity theorist adopts will depend on wider metaphysical and linguistic considerations that are strictly extraneous to the identity theory as such.
