 A critical, and distinctive, element of Plantinga’s account is that there are many unexemplified essences, i.e., essences that are not, in fact, the essences of anything, specifically, those he dubs haecceities. Haecceities are “purely nonqualitative” properties like being Plantinga, or perhaps, being identical with Plantinga, that do no more than characterize an object \(a\) as that very thing. Pretty clearly, haecceities are essences: Plantinga, for example, could not have existed and failed to have the property being Plantinga and it is not possible that anything else have that property. And, importantly, qua abstract property, like all essences, being Plantinga exists necessarily, whether exemplified or not—although, of course, had it not been exemplified, it wouldn’t have had the name “being Plantinga”, or any name at all, for that matter.
