The upshot of this is that there must be some kind of distinction within Socrates between his humanity as it is definable by its specific definition and his individual property (e.g., Lectura 2, d. 5, paragraph 24). In light of this distinction, it is, then, not contradictory (Chatton uses the expression “not repugnant to”) to Socrates’s humanity to be Plato’s even though it is in fact impossible for Socrates’s humanity to be Plato’s. This complicated line of counter-factual reasoning finds its inspiration in Scotus but takes centre-stage in Chatton’s discussion of natures and individuation. It is not repugnant to natures, taken as such, to be instantiated by multiple particular entities of the same kind at once. It is repugnant to natures, as individuated, to be instantiated by multiple particular entities of the same kind at once.
