Grasped, then, as an underlie in each order of Being, it can be no actualization of either: all that is allowed to it is to be a Potentiality, a weak and blurred phantasm, a thing incapable of a Shape of its own.
Its actuality is that of being a phantasm, the actuality of being a falsity; and the false in actualization is the veritably false, which again is Authentic Non-Existence.
So that Matter, as the Actualization of Non-Being, is all the more decidedly Non-Being, is Authentic Non-Existence.
Thus, since the very reality of its Nature is situated in Non-Being, it is in no degree the Actualization of any definite Being.
If it is to be present at all, it cannot be an Actualization, for then it would not be the stray from Authentic Being which it is, the thing having its Being in Non-Beingness: for, note, in the case of things whose Being is a falsity, to take away the falsity is to take away what Being they have, and if we introduce actualization into things whose Being and Essence is Potentiality, we destroy the foundation of their nature since their Being is Potentiality.
If Matter is to be kept as the unchanging substratum, we must keep it as Matter: that means — does it not? — that we must define it as a Potentiality and nothing more — or refute these considerations.
