A short entry this week, for next week we start on something bigger and of more importance: that God is not a body. Plus, this is the last hurrah of summer and many of us are not around. We could skip this, but why not be complete during the lull? Besides, I can’t see any of this being controversial, granting the previous arguments.
Chapter 19: That in God there is nothing violent or beside nature
1 HENCE the Philosopher concludes that in God there cannot be anything violent or outside nature. For whatever has in itself anything violent or beside nature,i has something added to itself: since that which belongs to a thing’s essence cannot be violent or beside nature. Now no simple thing has in itself anything that is added, for this would argue its being composite. Since then God is simple, as shown above, there can be nothing in Him that is violent or beside nature.
2 Further. The necessity resulting from compulsion is a necessity imposed by another. Now in God there is no necessity imposed by another, for He is necessary of Himself, and the cause of necessity in other things. Therefore nothing is compulsory in Him.ii
3 Moreover. Wherever there is violence, there can be something besides what belongs to a thing by its very nature: since violence is contrary to that which is according to nature. But it is not possible for anything to be in God that does not belong to Him according to His nature, since by His very nature He is necessary being, as shown above. Therefore there can be nothing violent in Him.iii
4 Again. Everything that is compelled or unnatural has a natural aptitude to be moved by another: because that which is done by compulsion has an external principle, without any concurrence on the part of the patient. Now God is altogether immovable, as shown above. Therefore nothing in Him can be violent or unnatural.iv
iDon’t take violent in its most common meaning. A pin in a hip to keep it swinging free is “violent” in St Thomas’s words. As the rest of this argument shows, since God is not in potential, he cannot possess anything that is besides His nature. Here is Aristotle on nature, from St Thomas’s footnote (to understand the language used if nothing else):
(4) ‘Nature’ means the primary material of which any natural object consists or out of which it is made, which is relatively unshaped and cannot be changed from its own potency, as e.g. bronze is said to be the nature of a statue and of bronze utensils, and wood the nature of wooden things; and so in all other cases; for when a product is made out of these materials, the first matter is preserved throughout. For it is in this way that people call the elements of natural objects also their nature, some naming fire, others earth, others air, others water, others something else of the sort, and some naming more than one of these, and others all of them.-(5) ‘Nature’ means the essence of natural objects…
(6) By an extension of meaning from this sense of ‘nature’ every essence in general has come to be called a ‘nature’, because the nature of a thing is one kind of essence.
From what has been said, then, it is plain that nature in the primary and strict sense is the essence of things which have in themselves, as such, a source of movement; for the matter is called the nature because it is qualified to receive this, and processes of becoming and growing are called nature because they are movements proceeding from this. And nature in this sense is the source of the movement of natural objects, being present in them somehow, either potentially or in complete reality.
Then much later, about privation, an important term:
We speak of ‘privation’ (1) if something has not one of the attributes which a thing might naturally have, even if this thing itself would not naturally have it; e.g. a plant is said to be ‘deprived’ of eyes. (2) If, though either the thing itself or its genus would naturally have an attribute, it has it not; e.g. a blind man and a mole are in different senses ‘deprived’ of sight; the latter in contrast with its genus, the former in contrast with his own normal nature. (3) If, though it would naturally have the attribute, and when it would naturally have it, it has it not; for blindness is a privation, but one is not ‘blind’ at any and every age, but only if one has not sight at the age at which one would naturally have it. Similarly a thing is called blind if it has not sight in the medium in which, and in respect of the organ in respect of which, and with reference to the object with reference to which, and in the circumstances in which, it would naturally have it. (4) The violent taking away of anything is called privation.
Also, on accident, “Accident’ has also (2) another meaning, i.e. all that attaches to each thing in virtue of itself but is not in its essence, as having its angles equal to two right angles attaches to the triangle. And accidents of this sort may be eternal, but no accident of the other sort is.”
iiNobody forces God to do anything, not even 800-pound gorillas. But you get the idea.
iiiIf somebody dents your skull with a lead pipe, he has done violence to your cranium. But don’t miss the subtle point, repeated: “it is not possible for anything to be in God that does not belong to Him according to His nature, since by His very nature He is necessary being”. A necessary being is one which must exist and in the form, or rather essence, it takes. If it were other than its essence, it would be contingent and not necessary.
ivThe note is back to the important Chapter 13, where it is proved God is the Unmoved Move, the Unchangeable Changer. God must be the first cause, and therefore cannot be done violence, nor can He be compelled against His will—and this is so despite some fanciful and overly literal interpretations one occasionally runs into. 5 Metaph. i. 6 (D. 4, v. 6).
