hat the more perfectly a cause is seen, the more of its effects
can be seen in it. For whoever has a lofty understanding, as soon as
one demonstrative principle is put before him can gather the knowledge
of many conclusions; but this is beyond one of a weaker intellect, for
he needs things to be explained to him separately. And so an intellect
can know all the effects of a cause and the reasons for those effects
in the cause itself, if it comprehends the cause wholly. Now no
created intellect can comprehend God wholly, as shown above
(A. 7). Therefore no created intellect in seeing God can know all
that God does or can do, for this would be to comprehend His power;
but of what God does or can do any intellect can know the more, the
more perfectly it sees God.

Reply Obj. 1: Gregory speaks as regards the object being sufficient,
namely, God, who in Himself sufficiently contains and shows forth all
things; but it does not follow that whoever sees God knows all
things, for he does not perfectly comprehend Him.

Reply Obj. 2: It is not necessary that whoever sees a mirror should
see all that is in the mirror, unless his glance comprehends the
mirror itself.

Reply Obj. 3: Although it is more to see God than to see all things
else, still it is a greater thing to see Him so that all things are
known in Him, than to see Him in such a way that not all things, but
the fewer or the more, are known in Him. For it has been shown in
this article that the more things are known in God according as He is
seen more or less perfectly.

Reply Obj. 4: The natural desire of the rational creature is to know
everything that belongs to the perfection of the intellect, namely,
the species and the genera of things and their types, and these
everyone who sees the Divine essence will see in God. But to know
other singulars, their thoughts and their deeds does not belong to
the perfection of the created intellect nor does its natural desire
go out to these things; neither, again, does it desire to know things
that exist not as yet, but which God can call into being. Yet if God
alone were seen, Who is the fount and principle of all being and of
all truth, He would so fill the natural desire of knowledge that
nothing else would be desired, and the seer would be completely
beatified. Hence Augustine says (Confess. v): "Unhappy the man who
knoweth all these" (i.e. all creatures) "and knoweth not Thee! but
happy whoso knoweth Thee although he know
