pend simply on His will, and
have no other cause. But this also is not admissible.

_On the contrary,_ Augustine says (Qq. lxxxiii, 28): "Every efficient
cause is greater than the thing effected." But nothing is greater than
the will of God. We must not then seek for a cause of it.

_I answer that,_ In no wise has the will of God a cause. In proof of
which we must consider that, since the will follows from the
intellect, there is cause of the will in the person who wills, in the
same way as there is a cause of the understanding, in the person that
understands. The case with the understanding is this: that if the
premiss and its conclusion are understood separately from each other,
the understanding the premiss is the cause that the conclusion is
known. If the understanding perceive the conclusion in the premiss
itself, apprehending both the one and the other at the same glance, in
this case the knowing of the conclusion would not be caused by
understanding the premisses, since a thing cannot be its own cause;
and yet, it would be true that the thinker would understand the
premisses to be the cause of the conclusion. It is the same with the
will, with respect to which the end stands in the same relation to the
means to the end, as do the premisses to the conclusion with regard to
the understanding.

Hence, if anyone in one act wills an end, and in another act the means
to that end, his willing the end will be the cause of his willing the
means. This cannot be the case if in one act he wills both end and
means; for a thing cannot be its own cause. Yet it will be true to say
that he wills to order to the end the means to the end. Now as God by
one act understands all things in His essence, so by one act He wills
all things in His goodness. Hence, as in God to understand the cause
is not the cause of His understanding the effect, for He understands
the effect in the cause, so, in Him, to will an end is not the cause
of His willing the means, yet He wills the ordering of the means to
the end. Therefore, He wills this to be as means to that; but does not
will this on account of that.

Reply Obj. 1: The will of God is reasonable, not because anything is
to God a cause of willing, but in so far as He wills one thing to be
on account of another.

Reply Obj. 2: Since God wills effects to proceed from definite
causes, for the preservation of order in the universe, it is not
unreasonable to seek for causes secondary to the di
