 To say that a mental object has semantic properties is, paradigmatically, to say that it is about, or true or false of, an object or objects, or that it is true or false simpliciter. Suppose I think that democracy is dying. I am thinking about democracy, and if what I think of it (that it is dying) is true of it, then my thought is true. According to RTM such states are to be explained as relations between agents and mental representations. To think that democracy is dying is to token in some way a mental representation whose content is that democracy is dying. On this view, the semantic properties of mental states are the semantic properties of the representations they are relations to.
