FIRST ARTICLE [I, Q. 17, Art. 1]

Whether Falsity Exists in Things?

Objection 1: It appears that falsity does not exist in things. For

Augustine says (Soliloq. ii, 8), "If the true is that which is, it

will be concluded that the false exists nowhere; whatever reason may

appear to the contrary."

Obj. 2: Further, false is derived from _fallere_ (to deceive). But

things do not deceive; for, as Augustine says (De Vera Relig. 33),

they show nothing but their own species. Therefore the false is not

found in things.

Obj. 3: Further, the true is said to exist in things by conformity to

the divine intellect, as stated above (Q. 16). But everything, in so

far as it exists, imitates God. Therefore everything is true without

admixture of falsity; and thus nothing is false.

_On the contrary,_ Augustine says (De Vera Relig. 34): "Every body is a

true body and a false unity: for it imitates unity without being

unity." But everything imitates the divine unity yet falls short of

it. Therefore in all things falsity exists.

_I answer that,_ Since true and false are opposed, and since opposites

stand in relation to the same thing, we must needs seek falsity, where

primarily we find truth; that is to say, in the intellect. Now, in

things, neither truth nor falsity exists, except in relation to the

intellect. And since every thing is denominated simply by what belongs

to it _per se,_ but is denominated relatively by what belongs to it

accidentally; a thing indeed may be called false simply when compared

with the intellect on which it depends, and to which it is compared

_per se_ but may be called false relatively as directed to another

intellect, to which it is compared accidentally. Now natural things

depend on the divine intellect, as artificial things on the human.

Wherefore artificial things are said to be false simply and in

themselves, in so far as they fall short of the form of the art;

whence a craftsman is said to produce a false work, if it falls short

of the proper operation of his art.

In things that depend on God, falseness cannot be found, in so far as

they are compared with the divine intellect; since whatever takes

place in things proceeds from the ordinance of that intellect, unless

perhaps in the case of voluntary agents only, who have it in their

power to withdraw themselves from what is so ordained; wherein

consists the evil of sin. Thus sins themselves are called untruths and

lies in the Scriptures, according to the words of the text, "Why do

you love vanity, and seek after lying?" (Ps. 4:3): as on the other

hand virtuous deeds are called the "truth of life" as being obedient

to the order of the divine intellect. Thus it is said, "He that doth

truth, cometh to the light" (John 3:21).

But in relation to our intellect, natural things which are compared

thereto accidentally, can be called false; not simply, but relatively;

and that in two ways. In one way according to the thing signified, and

thus a thing is said to be false as being signified or represented by

word or thought that is false. In this respect anything can be said to

be false as regards any quality not possessed by it; as if we should

say that a diameter is a false commensurable thing, as the Philosopher

says (Metaph. v, 34). So, too, Augustine says (Soliloq. ii, 10): "The

true tragedian is a false Hector": even as, on the contrary, anything

can be called true, in regard to that which is becoming to it. In

another way a thing can be called false, by way of cause--and thus a

thing is said to be false that naturally begets a false opinion. And

whereas it is innate in us to judge things by external appearances,

since our knowledge takes its rise from sense, which principally and

naturally deals with external accidents, therefore those external

accidents, which resemble things other than themselves, are said to be

false with respect to those things; thus gall is falsely honey; and

tin, false gold. Regarding this, Augustine says (Soliloq. ii, 6): "We

call those things false that appear to our apprehension like the

true:" and the Philosopher says (Metaph. v, 34): "Things are called

false that are naturally apt to appear such as they are not, or what

they are not." In this way a man is called false as delighting in

false opinions or words, and not because he can invent them; for in

this way many wise and learned persons might be called false, as

stated in _Metaph._ v, 34.

Reply Obj. 1: A thing compared with the intellect is said to be true

in respect to what it is; and false in respect to what it is not.

Hence, "The true tragedian is a false Hector," as stated in Soliloq.

ii, 6. As, therefore, in things that are is found a certain

non-being, so in things that are is found a degree of falseness.

Reply Obj. 2: Things do not deceive by their own nature, but by

accident. For they give occasion to falsity, by the likeness they

bear to things which they actually are not.

Reply Obj. 3: Things are said to be false, not as compared with the

divine intellect, in which case they would be false simply, but as

compared with our intellect; and thus they are false only relatively.

To the argument which is urged on the contrary, likeness or defective

representation does not involve the idea of falsity except in so far

as it gives occasion to false opinion. Hence a thing is not always

said to be false, because it resembles another thing; but only when

the resemblance is such as naturally to produce a false opinion, not

in any one case, but in the majority of instances.
