1 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.
1 Ad primum sic proceditur. Videtur quod falsitas non sit in rebus. Dicit enim Augustinus, in libro Soliloq., si verum est id quod est, falsum non esse uspiam concludetur, quovis repugnante.
2 Objection 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.
2 Praeterea, falsum dicitur a fallendo. Sed res non fallunt, ut dicit Augustinus in libro de vera Relig., quia non ostendunt aliud quam suam speciem. Ergo falsum in rebus non invenitur.
3 Objection 3: Further, the true is said to exist in things by conformity to the divine intellect, as stated above Question 16). But everything, in so far as it exists, imitates God. Therefore everything is true without admixture of falsity; and thus nothing is false.
3 Praeterea, verum dicitur in rebus per comparationem ad intellectum divinum, ut supra dictum est. Sed quaelibet res, inquantum est, imitatur Deum. Ergo quaelibet res vera est, absque falsitate. Et sic nulla res est falsa.
4 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.
4 Sed contra est quod dicit Augustinus, in libro de vera Relig., quod omne corpus est verum corpus et falsa unitas; quia imitatur unitatem, et non est unitas. Sed quaelibet res imitatur divinam bonitatem, et ab ea deficit. Ergo in omnibus rebus est falsitas.
5 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 Jn. 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.
5 Respondeo dicendum quod, cum verum et falsum opponantur; opposita autem sunt circa idem; necesse est ut ibi prius quaeratur falsitas, ubi primo veritas invenitur, hoc est in intellectu. In rebus autem neque veritas neque falsitas est, nisi per ordinem ad intellectum. Et quia unumquodque secundum id quod convenit ei per se, simpliciter nominatur; secundum autem id quod convenit ei per accidens, non nominatur nisi secundum quid; res quidem simpliciter falsa dici posset per comparationem ad intellectum a quo dependet, cui comparatur per se; in ordine autem ad alium intellectum, cui comparatur per accidens, non posset dici falsa nisi secundum quid.
Dependent autem ab intellectu divino res naturales, sicut ab intellectu humano res artificiales. Dicuntur igitur res artificiales falsae simpliciter et secundum se, inquantum deficiunt a forma artis, unde dicitur aliquis artifex opus falsum facere, quando deficit ab operatione artis. Sic autem in rebus dependentibus a Deo, falsitas inveniri non potest per comparationem ad intellectum divinum, cum quidquid in rebus accidit, ex ordinatione divini intellectus procedat, nisi forte in voluntariis agentibus tantum, in quorum potestate est subducere se ab ordinatione divini intellectus; in quo malum culpae consistit, secundum quod ipsa peccata falsitates et mendacia dicuntur in Scripturis, secundum illud Psalmi IV, ut quid diligitis vanitatem et quaeritis mendacium? Sicut per oppositum operatio virtuosa veritas vitae nominatur, inquantum subditur ordini divini intellectus; sicut dicitur Ioan.
III, qui facit veritatem, venit ad lucem. Sed per ordinem ad intellectum nostrum, ad quem comparantur res naturales per accidens, possunt dici falsae, non simpliciter, sed secundum quid. Et hoc dupliciter. Uno modo, secundum rationem significati, ut dicatur illud esse falsum in rebus, quod significatur vel repraesentatur oratione vel intellectu falso. Secundum quem modum quaelibet res potest dici esse falsa, quantum ad id quod ei non inest, sicut si dicamus diametrum esse falsum commensurabile, ut dicit philosophus in V Metaphys.;
et sicut dicit Augustinus, in libro Soliloq., quod tragoedus est falsus Hector. Sicut e contrario potest unumquodque dici verum, secundum id quod competit ei. Alio modo, per modum causae. Et sic dicitur res esse falsa, quae nata est facere de se opinionem falsam. Et quia innatum est nobis per ea quae exterius apparent de rebus iudicare, eo quod nostra cognitio a sensu ortum habet, qui primo et per se est exteriorum accidentium; ideo ea quae in exterioribus accidentibus habent similitudinem aliarum rerum, dicuntur esse falsa secundum illas res; sicut fel est falsum mel, et stannum est falsum argentum.
Et secundum hoc dicit Augustinus, in libro Soliloq., quod eas res falsas nominamus, quae verisimilia apprehendimus. Et philosophus dicit, in V Metaphys., quod falsa dicuntur quaecumque apta nata sunt apparere aut qualia non sunt, aut quae non sunt. Et per hunc modum etiam dicitur homo falsus, inquantum est amativus falsarum opinionum vel locutionum. Non autem ex hoc quod potest eas confingere, quia sic etiam sapientes et scientes falsi dicerentur, ut dicitur in V Metaphys.
6 Reply to Objection 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.
6 Ad primum ergo dicendum quod res comparata ad intellectum, secundum id quod est, dicitur vera, secundum id quod non est, dicitur falsa. Unde verus tragoedus est falsus Hector, ut dicitur in II Soliloq. Sicut igitur in his quae sunt, invenitur quoddam non esse; ita in his quae sunt, invenitur quaedam ratio falsitatis.
7 Reply to Objection 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.
7 Ad secundum dicendum quod res per se non fallunt, sed per accidens. Dant enim occasionem falsitatis, eo quod similitudinem eorum gerunt, quorum non habent existentiam.
8 Reply to Objection 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.
8 Ad tertium dicendum quod per comparationem ad intellectum divinum non dicuntur res falsae, quod esset eas esse falsas simpliciter, sed per comparationem ad intellectum nostrum, quod est eas esse falsas secundum quid. Ad quartum, quod in oppositum obiicitur, dicendum quod similitudo vel repraesentatio deficiens non inducit rationem falsitatis, nisi inquantum praestat occasionem falsae opinionis. Unde non ubicumque est similitudo, dicitur res falsa, sed ubicumque est talis similitudo, quae nata est facere opinionem falsam, non cuicumque, sed ut in pluribus.
