 As robust as the haecceitist solution is, many actualists find that it grates against some very strong intuitions, especially about the nature of properties.   But there is a deeper issue dividing the haecceitists from other actualists. To clarify, consider that many propositions are singular in form. That is, unlike general propositions like all whales are mammals, some propositions are “directly about” specific individuals—for example, the proposition Marie Curie was a German citizen. Call the individuals a singular proposition is directly about the subjects of the proposition. Singular propositions are typically expressed by means of sentences involving names, pronouns, indexicals, or other devices of direct reference. As we’ve seen, possibilists believe that there are singular propositions whose subjects are not actual, viz., propositions about mere possibilia: for the possibilist, recall,  (2)  is grounded in singular propositions of the form \(a\) is Bergoglio’s child, for possibilia \(a\). Similarly, haecceitists like Plantinga, although actualists in the strict sense, also believe there are singular possibilities that are in a derivative but clear sense directly about things that don’t exist, viz., those possibilities involving unexemplified haecceities like \(h\) is coexemplified with being Bergoglio’s child. Say that a strict actualist is an actualist who rejects the idea that there are, or even could be, singular propositions that are directly about things that do not exist in either the possibilist’s or the haecceitist’s sense. It follows that, had some actually existing individual \(a\) failed to exist, there would have been no singular propositions about \(a\); or, as Prior puts it, there would have been no facts about \(a,\) not even the fact that \(a\) fails to exist (see, e.g., Prior 1957: 48–49); or again: singular propositions supervene on the individuals they are about. For the strict actualist, then, necessarily, all propositions are either wholly general or, at most, are directly about existing individuals only.
