 Presumably, if logic is normative for thinking or reasoning, its normative force will stem, at least in part, from the fact that truth bearers which act as the relata of our consequence relation and the bearers of other logical properties are identical to (or at least are very closely related in some other way) to the objects of thinking or reasoning: the contents of one’s mental states or acts such as the content of one’s beliefs or inferences, for example. For present purposes I will assume the identity between truth-bearers and the contents of our attitudes, and I will assume them to be propositions.
