y speaking, of divine truth; unless
perhaps in so far as truth is appropriated to the Son, Who has a
principle. But if we speak of divine truth in its essence, we cannot
understand this unless the affirmative must be resolved into the
negative, as when one says: "the Father is of Himself, because He is
not from another." Similarly, the divine truth can be called a
"likeness to the principle," inasmuch as His existence is not
dissimilar to His intellect.

Reply Obj. 3: Not-being and privation have no truth of themselves,
but only in the apprehension of the intellect. Now all apprehension
of the intellect is from God. Hence all the truth that exists in the
statement--"that a person commits fornication is true"--is entirely
from God. But to argue, "Therefore that this person fornicates is
from God", is a fallacy of Accident.

SIXTH ARTICLE [I, Q. 16, Art. 6]

Whether There Is Only One Truth, According to Which All Things Are True?

Objection 1: It seems that there is only one truth, according to which
all things are true. For according to Augustine (De Trin. xv, 1),
"nothing is greater than the mind of man, except God." Now truth is
greater than the mind of man; otherwise the mind would be the judge of
truth: whereas in fact it judges all things according to truth, and
not according to its own measure. Therefore God alone is truth.
Therefore there is no other truth but God.

Obj. 2: Further, Anselm says (De Verit. xiv), that, "as is the
relation of time to temporal things, so is that of truth to true
things." But there is only one time for all temporal things.
Therefore there is only one truth, by which all things are true.

_On the contrary,_ it is written (Ps. 11:2), "Truths are decayed from
among the children of men."

_I answer that,_ In one sense truth, whereby all things are true, is
one, and in another sense it is not. In proof of which we must
consider that when anything is predicated of many things univocally,
it is found in each of them according to its proper nature; as animal
is found in each species of animal. But when anything is predicated of
many things analogically, it is found in only one of them according to
its proper nature, and from this one the rest are denominated. So
healthiness is predicated of animal, of urine, and of medicine, not
that health is only in the animal; but from the health of the animal,
medicine is called healthy, in so far as it is the cause of heal
