in that which is measured.

But where a relation originates in causation, as between that which is
active and that which is passive, it does not always concern both terms.
True, that which is acted upon, or set in motion, or produced, must be
related to the source of these modifications, since every effect is
dependent upon its cause. And it is equally true that such causes or
agencies are in some cases related to their effects, namely, when the
production of those effects redounds in some way to the well-being of
the cause itself. This is evidently what happens when like begets like,
and thereby perpetuates, so far as may be, its own species.... There
are cases, nevertheless, in which a thing, without being related, has
other things related to it. The cognizing subject is related to that
which is the object of cognition--to a thing which is outside the mind.
But the thing itself is in no way affected by this cognition, since the
mental process is confined to the mind, and therefore does not bring
about any change in the object. Hence the relation established by the
act of knowing cannot be in that which is known.

The same holds good of sensation. For though the physical object sets up
changes in the sense-organ, and is related to it as other physical
agencies are related to the things on which they act, still, the
sensation implies, over and above the organic change, a subjective
activity of which the external activity is altogether devoid. Likewise,
we say that a man is at the right of a pillar because, with his power of
locomotion, he can take his stand at the right or the left, before or
behind, above or below. But obviously these relations, vary them as we
will, imply nothing in the stationary pillar, though they are real in
the man who holds or changes his position. Once more, a coin has nothing
to do with the action that gives it its value, since this action is a
human convention; and a man is quite apart from the process which
produces his image. Between a man and his portrait there is a relation,
but this is real in the portrait only. Between the coin and its current
value there is a relation, but this is not real in the coin.

Now for the application. God's action is not to be understood as going
out from Him and terminating in that which He creates. His action is
Himself; consequently altogether apart from the genus of created being
whereby the creature is related to Him. And again, he gains nothing by
cr
