 Moreover, the second sentence of III.vi.6, where he inserts the clarification that a real essence is “…that particular constitution, which every Thing has within it self, without any relation to any thing without it,” appears to say that there can be real essences of unsorted individuals. If a real essence is definable as a corpuscular structure cum causal powers that a body has independently of anything else, then it seems to follow that there are individual real essences independently of how we sort them. That is, if every natural substance has some submicroscopic corpuscular constitution on which its observable qualities depend, then it seems to follow that unsorted individuals have a real essence (see Owen 1991 and Vienne  1993).[5]
