How so? Doesn’t interaction amongst the physical by physical means produce physical properties? No violation of “ex nihilo nihil fit”?
So long as an act or existence does not violate the law of noncontradiction really or formally it is entirely positable; even if it violates all of observed reality.
The premise underlying the idea that two properties can inhere in one is understandable. We can say this man is both “Red” and “Rational”; because the individual “man” can be predicated by genras which are distinct.
However; to this can be replied that as the Man and his Mind are substantially and really distinct; such predication would be only to an
in toto composite.
It follows from this then; that it seems contrary to observed reality that two substantially different properties can be inhered in a singular; however such contrarity is not a necessarily inherant contrarity; but an observed one. This is clearly distinct; thus; it is positable that a singularity that has a real unity is both predicated by properties of these seperate genera. However; it does not follow from this that there is a necessity for such to inhere in a specific substance.
So; as it is not logically contrary necessarily that two properties inhere in one; a singularity may be brought about functioning in this way. Despite the fact that no such operation has been observed (I am unable to even sensibly conceive an example) it does follow that this is
possible within the Theology of the Church defined by The Doctor of the Church St. Peter Damian in
De divina omnipotentia, which sets the precedent that anything which is not
evil or
impossible can be brought about by God; even things which are very strange and difficult to imagine. Damian demonstrates that God can restore virginity to someone who has lost it; because this act; (as an example) is possible and not evil.
Likewise; it is possible for God to inhere two properties in a single substance; as this does not entail a contradiction; nor is it evil - thus it can be done. That said; it is not by necessity that this act must occur within a physical substance; nor does it in any way teach that mental properties are properties applicable to physical substances in General.
To put it simply; Property Dualism is incorrect; but
ONE of it’s ideas; the idea that two properties can inhere within one substance; does not violate the law of noncontradiction and is thus
possible in accordance with the teachings of the Church.
