Reply Obj. 2: In things willed for the sake of the end, the whole reason for our being moved is the end, and this it is that moves the will, as most clearly appears in things willed only for the sake of the end. He who wills to take a bitter draught, in doing so wills nothing else than health; and this alone moves his will. It is different with one who takes a draught that is pleasant, which anyone may will to do, not only for the sake of health, but also for its own sake. Hence, although God wills things apart from Himself only for the sake of the end, which is His own goodness, it does not follow that anything else moves His will, except His goodness. So, as He understands things apart from Himself by understanding His own essence, so He wills things apart from Himself by willing His own goodness.
Reply Obj. 3: From the fact that His own goodness suffices the divine will, it does not follow that it wills nothing apart from itself, but rather that it wills nothing except by reason of its goodness. Thus, too, the divine intellect, though its perfection consists in its very knowledge of the divine essence, yet in that essence knows other things.
Reply Obj. 4: As the divine intellect is one, as seeing the many only in the one, in the same way the divine will is one and simple, as willing the many only through the one, that is, through its own goodness. _______________________
THIRD ARTICLE [I, Q. 19, Art. 3]
Whether Whatever God Wills He Wills Necessarily?
Objection 1: It seems that whatever God wills He wills necessarily. For everything eternal is necessary. But whatever God wills, He wills from eternity, for otherwise His will would be mutable. Therefore whatever He wills, He wills necessarily.
Obj. 2: Further, God wills things apart from Himself, inasmuch as He wills His own goodness. Now God wills His own goodness necessarily. Therefore He wills things apart from Himself necessarily.
Obj. 3: Further, whatever belongs to the nature of God is necessary, for God is of Himself necessary being, and the principle of all necessity, as above shown (Q. 2, A. 3). But it belongs to His nature to will whatever He wills; since in God there can be nothing over and above His nature as stated in Metaph. v, 6. Therefore whatever He wills, He wills necessarily.
Obj. 4: Further, being that is not necessary, and being that is possible not to be, are one and the same thing. If, therefore, God does not necessarily will a thing that He wills, it is possible for Him not to will it, and therefore possible for Him to will what He does not will. And so the divine will is contingent upon one or the other of two things, and imperfect, since everything contingent is imperfect and mutable.
Obj. 5: Further, on the part of that which is indifferent to one or the other of two things, no action results unless it is inclined to one or the other by some other power, as the Commentator [*Averroes] says in Phys. ii. If, then, the Will of God is indifferent with regard to anything, it follows that His determination to act comes from another; and thus He has some cause prior to Himself.
