You can have a substance without “person”. All creatures beneath humans are non-personal substances (I’m afraid that this applies even to dogs and cats).Thanks - I will take it that an entity is both substance and person. The issue is - what is missing from substance if there is no person. This goes back to the OP.
“Person” adds an indefinable singularity. What is meant by “singularity” here is that “person” falls outside all Aristotelian categories. “Person” belongs to the “thisness” or “haecceitas” of a rational being (to use Scotus’ terminology).
It’s important to stress that the individuality of “person” does not belong simply to the “matter” - “person” is an ontological excellence in a way that “matter” can never be. Otherwise, how would we be able the “individuality” of angels or even God, i.e., personal beings with no matter?
On the “formal” side, a “person” is not just a sum of attributes (material, mental or otherwise). A “person” is not a congeries of universals.
It is being a “person” that especially makes a human being an image of God (not just rational nature).
But “person” requires a rational nature. This is true even of God.
It’s just that “rational nature” is not the same ontological principle as “person” - although there is no being with a rational nature who is not also a “person”.
Human beings, in other words, are not just instantiations of a rational nature (or form or eidos).
There is another excellence that “person” adds to “substance”.
This excellence can only be expressed as a “who” instead of a “what” (see Robert Spaemann for more detail).
