This is indeed the very essence of distribution, that a universal is predicable, not singly or collectively, but severally and similarly of each and every individual of a kind, or total of similar individuals.
The universal of this stage is the universal of fact, what is recognized as predicable of a plurality of subjects.
In this irreversible catena proceeding from ground to consequent, we have left far behind such things as the formal parity of genus and differentia considered as falling under the same predicable, 3 and hence justified in part Porphyry's divergence from the scheme of predicables.
Meanwhile let us call them "intelligible," as being valid for all who comprehend the real and actual by thought, although no such forms are predicable of the real and actual themselves.

Many so-called accidents are predicable necessarily of any particular persons.
Many attributes, too, were predicable, even to the end, in an external and accidental way, not being derivable from the essence of the subject.
