Perhaps the identity in substance with differentiation in reason will be defended on the ground that Privation does not point to something present but precisely to an absence, to something absent, to the negation or lack of Real-being: the case would be like that of the affirmation of non-existence, where there is no real predication but simply a denial.
Is, then, this Privation simply a non-existence?
If a non-existence in the sense that it is not a thing of Real-being, but belongs to some other Kind of existent, we have still two Principles, one referring directly to the substratum, the other merely exhibiting the relation of the Privation to other things.
Or we might say that the one concept defines the relation of substratum to what is not substratum, while that of Privation, in bringing out the indeterminateness of Matter, applies to the Matter in itself: but this still makes Privation and Matter two in reason though one in substratum.
Now if Matter possesses an identity — though only the identity of being indeterminate, unfixed and without quality — how can we bring it so under two principles?
