virtually the cause of others, that is, of things which He can make, and which nevertheless are never made.
Reply Obj. 2: The fact that knowledge is derived from things known does not essentially belong to speculative knowledge, but only accidentally in so far as it is human.
In answer to what is objected on the contrary, we must say that perfect knowledge of operable things is obtainable only if they are known in so far as they are operable. Therefore, since the knowledge of God is in every way perfect, He must know what is operable by Him, formally as such, and not only in so far as they are speculative.
Nevertheless this does not impair the nobility of His speculative knowledge, forasmuch as He sees all things other than Himself in Himself, and He knows Himself speculatively; and so in the speculative knowledge of Himself, he possesses both speculative and practical knowledge of all other things.
QUESTION 15 OF IDEAS (In Three Articles) After considering the knowledge of God, it remains to consider ideas.
And about this there are three points of inquiry: (1) Whether there are ideas?
(2) Whether they are many, or one only?
(3) Whether there are ideas of all things known by God?
Whether There Are Ideas?
Objection 1: It seems that there are no ideas. For Dionysius says (Div. Nom. vii), that God does not know things by ideas. But ideas are for nothing else except that things may be known through them.
Therefore there are no ideas.
Obj. 2: Further, God knows all things in Himself, as has been already said (Q. 14, A. 5). But He does not know Himself through an idea; neither therefore other things.
Obj. 3: Further, an idea is considered to be the principle of knowledge and action. But the divine essence is a sufficient principle of knowing and effecting all things. It is not therefore necessary to suppose ideas.
_On the contrary,_ Augustine says (Octog. Tri. Quaest. qu. xlvi), "Such is the power inherent in ideas, that no one can be wise unless they are understood."
_I answer that,_ It is necessary to suppose ideas in the divine mind.
For the Greek word _Idea_ is in Latin _Forma._ Hence by ideas are understood the forms of things, existing apart from the things themselves. Now the form of anything existing apart from the thing itself can be for one of two ends: either to be the type of that of which it is called the form, or to be the principle of the knowledge of that thing, inasmuch as the forms of things knowable are said to be in him who knows them. In either case we must suppose ideas, as is clear for the following reason: In all things not generated by chance, the form must be the end of any generation whatsoever. But an agent does not act on account of the form, except in so far as the likeness of the form is in the agent, as may happen in two ways. For in some agents the form of the thing to be made pre-exists according to its natural being, as in those that act by their nature; as a man generates a man, or fire generates fire. Whereas in other agents (the form of the thing to be made pre-exists) according to intelligible being, as in those that act by the intellect; and thus the likeness of a house pre-exists in the mind of the builder. And this may be called the idea of the house, since the builder intends to build his house like to the form conceived in his mind. As then the world was not made by chance, but by God acting by His intellect, as will appear later (Q. 46, A. 1), there must exist in the divine mind a form to the likeness of which the world was made. And in this the notion of an idea consists.
Reply Obj. 1: God does not understand things according to an idea existing outside Himself. Thus Aristotle (Metaph. ix) rejects the opinion of Plato, who held that ideas existed of themselves, and not in the intellect.
Reply Obj. 2: Although God knows Himself and all else by His own essence, yet His essence is the operative principle of all things, except of Himself. It has therefore the nature of an idea with respect to other things; though not with respect to Himself.
Reply Obj. 3: God is the similitude of all things according to His essence; therefore an idea in God is identical with His essence.
Whether Ideas Are Many?
Objection 1: It seems that ideas are not many. For an idea in God is His essence. But God's essence is one only. Therefore there is only one idea.
Obj. 2: Further, as the idea is the principle of knowing and operating, so are art and wisdom. But in God there are not several arts or wisdoms. Therefore in Him there is no plurality of ideas.
Obj. 3: Further, if it be said that ideas are multiplied according to their relations to different creatures, it may be argued on the contrary that the plurality of ideas is eternal. If, then, ideas are many, but creatures temporal, then the temporal must be the cause of the eternal.
Obj. 4: Further, these relations are either real in creatures only, or in God also. If in creatures only, since creatures are not from eternity, the plurality of ideas cannot be from eternity, if ideas are multiplied only according to these relations. But if they are real in God, it follows that there is a real plurality in God other than the plurality of Persons: and this is against the teaching of Damascene (De Fide Orth. i, 10), who says, in God all things are one, except "ingenerability, generation, and procession." Ideas therefore are not many.
_On the contrary,_ Augustine says (Octog. Tri. Quaest. qu. xlvi), "Ideas are certain principal forms, or permanent and immutable types of things, they themselves not being formed. Thus they are eternal, and existing always in the same manner, as being contained in the divine intelligence. Whilst, however, they themselves neither come into being nor decay, yet we say that in accordance with them everything is formed that can rise or decay, and all that actually does so."
_I answer that,_ It must necessarily be held that ideas are many. In proof of which it is to be considered that in every effect the ultimate end is the proper intention of the principal agent, as the order of an army (is the proper intention) of the general. Now the highest good existing in things is the good of the order of the universe, as the Philosopher clearly teaches in _Metaph._ xii.
Therefore the order of the universe is properly intended by God, and is not the accidental result of a succession of agents, as has been supposed by those who have taught that God created only the first creature, and that this creature created the second creature, and so on, until this great multitude of beings was produced. According to this opinion God would have the idea of the first created thing alone; whereas, if the order itself of the universe was created by Him immediately, and intended by Him, He must have the idea of the order of the universe. Now there cannot be an idea of any whole, unless particular ideas are had of those parts of which the whole is made; just as a builder cannot conceive the idea of a house unless he has the idea of each of its parts. So, then, it must needs be that in the divine mind there are the proper ideas of all things. Hence Augustine says (Octog. Tri. Quaest. qu. xlvi), "that each thing was created by God according to the idea proper to it," from which it follows that in the divine mind ideas are many. Now it can easily be seen how this is not repugnant to the simplicity of God, if we consider that the idea of a work is in the mind of the operator as that which is understood, and not as the image whereby he understands, which is a form that makes the intellect in act. For the form of the house in the mind of the builder, is something understood by him, to the likeness of which he forms the house in matter. Now, it is not repugnant to the simplicity of the divine mind that it understand many things; though it would be repugnant to its simplicity were His understanding to be formed by a plurality of images. Hence many ideas exist in the divine mind, as things understood by it; as can be proved thus. Inasmuch as He knows His own essence perfectly, He knows it according to every mode in which it can be known. Now it can be known not only as it is in itself, but as it can be participated in by creatures according to some degree of likeness. But every creature has its own proper species, according to which it participates in some degree in likeness to the divine essence. So far, therefore, as God knows His essence as capable of such imitation by any creature, He knows it as the particular type and idea of that creature; and in like manner as regards other creatures. So it is clear that God understands many particular types of things and these are many ideas.
Reply Obj. 1: The divine essence is not called an idea in so far as it is that essence, but only in so far as it is the likeness or type of this or that thing. Hence ideas are said to be many, inasmuch as many types are understood through the self-same essence.
Reply Obj. 2: By wisdom and art we signify that by which God understands; but an idea, that which God understands. For God by one understands many things, and that not only according to what they are in themselves, but also according as they are understood, and this is to understand the several types of things. In the same way, an architect is said to understand a house, when he understands the form of the house in matter. But if he understands the form of a house, as devised by himself, from the fact that he understands that he understands it, he thereby understands the type or idea of the house.
Now not only does God understand many things by His essence, but He also understands that He understands many things by His essence. And this means that He understands the several types of things; or that many ideas are in His intellect as understood by Him.
Reply Obj. 3: Such relations, whereby ideas are multiplied, are caused not by the things themselves, but by the divine intellect comparing its own essence with these things.
Reply Obj. 4: Relations multiplying ideas do not exist in created things, but in God. Yet they are not real relations, such as those whereby the Persons are distinguished, but relations understood by God.
Whether There Are Ideas of All Things That God Knows?
Objection 1: It seems that there are not ideas in God of all things that He knows. For the idea of evil is not in God; since it would follow that evil was in Him. But evil things are known by God.
Therefore there are not ideas of all things that God knows.
Obj. 2: Further, God knows things that neither are, nor will be, nor have been, as has been said above (A. 9). But of such things there are no ideas, since, as Dionysius says (Div. Nom. v): "Acts of the divine will are the determining and effective types of things."
Therefore there are not in God ideas of all things known by Him.
Obj. 3: Further, God knows primary matter, of which there can be no idea, since it has no form. Hence the same conclusion.
Obj. 4: Further, it is certain that God knows not only species, but also genera, singulars, and accidents. But there are not ideas of these, according to Plato's teaching, who first taught ideas, as Augustine says (Octog. Tri. Quaest. qu. xlvi). Therefore there are not ideas in God of all things known by Him.
_On the contrary,_ Ideas are types existing in the divine mind, as is clear from Augustine (Octog. Tri. Quaest. qu. xlvi). But God has the proper types of all things that He knows; and therefore He has ideas of all things known by Him.
_I answer that,_ As ideas, according to Plato, are principles of the knowledge of things and of their generation, an idea has this twofold office, as it exists in the mind of God. So far as the idea is the principle of the making of things, it may be called an "exemplar," and belongs to practical knowledge. But so far as it is a principle of knowledge, it is properly called a "type," and may belong to speculative knowledge also. As an exemplar, therefore, it has respect to everything made by God in any period of time; whereas as a principle of knowledge it has respect to all things known by God, even though they never come to be in time; and to all things that He knows according to their proper type, in so far as they are known by Him in a speculative manner.
Reply Obj. 1: Evil is known by God not through its own type, but through the type of good. Evil, therefore, has no idea in God, neither in so far as an idea is an "exemplar" nor as a "type."
Reply Obj. 2: God has no practical knowledge, except virtually, of things which neither are, nor will be, nor have been. Hence, with respect to these there is no idea in God in so far as idea signifies an "exemplar" but only in so far as it denotes a "type."
Reply Obj. 3: Plato is said by some to have considered matter as not created; and therefore he postulated not an idea of matter but a concause with matter. Since, however, we hold matter to be created by God, though not apart from form, matter has its idea in God; but not apart from the idea of the composite; for matter in itself can neither exist, nor be known.
Reply Obj. 4: Genus can have no idea apart from the idea of species, in so far as idea denotes an "exemplar"; for genus cannot exist except in some species. The same is the case with those accidents that inseparably accompany their subject; for these come into being along with their subject. But accidents which supervene to the subject, have their special idea. For an architect produces through the form of the house all the accidents that originally accompany it; whereas those that are superadded to the house when completed, such as painting, or any other such thing, are produced through some other form. Now individual things, according to Plato, have no other idea than that of species; both because particular things are individualized by matter, which, as some say, he held to be uncreated and the concause with the idea; and because the intention of nature regards the species, and produces individuals only that in them the species may be preserved. However, divine providence extends not merely to species; but to individuals as will be shown later (Q. 22, A. 3).
QUESTION 16 OF TRUTH (In Eight Articles) Since knowledge is of things that are true, after the consideration of the knowledge of God, we must inquire concerning truth. About this there are eight points of inquiry: (1) Whether truth resides in the thing, or only in the intellect?
(2) Whether it resides only in the intellect composing and dividing?
(3) On the comparison of the true to being.
(4) On the comparison of the true to the good.
(5) Whether God is truth?
(6) Whether all things are true by one truth, or by many?
(7) On the eternity of truth.
(8) On the unchangeableness of truth.
Whether Truth Resides Only in the Intellect?
Objection 1: It seems that truth does not reside only in the intellect, but rather in things. For Augustine (Soliloq. ii, 5) condemns this definition of truth, "That is true which is seen"; since it would follow that stones hidden in the bosom of the earth would not be true stones, as they are not seen. He also condemns the following, "That is true which is as it appears to the knower, who is willing and able to know," for hence it would follow that nothing would be true, unless someone could know it. Therefore he defines truth thus: "That is true which is." It seems, then, that truth resides in things, and not in the intellect.
Obj. 2: Further, whatever is true, is true by reason of truth. If, then, truth is only in the intellect, nothing will be true except in so far as it is understood. But this is the error of the ancient philosophers, who said that whatever seems to be true is so.
Consequently mutual contradictories seem to be true as seen by different persons at the same time.
Obj. 3: Further, "that, on account of which a thing is so, is itself more so," as is evident from the Philosopher (Poster. i). But it is from the fact that a thing is or is not, that our thought or word is true or false, as the Philosopher teaches (Praedicam. iii). Therefore truth resides rather in things than in the intellect.
_On the contrary,_ The Philosopher says (Metaph. vi), " The true and the false reside not in things, but in the intellect."
_I answer that,_ As the good denotes that towards which the appetite tends, so the true denotes that towards which the intellect tends. Now there is this difference between the appetite and the intellect, or any knowledge whatsoever, that knowledge is according as the thing known is in the knower, whilst appetite is according as the desirer tends towards the thing desired. Thus the term of the appetite, namely good, is in the object desirable, and the term of the intellect, namely true, is in the intellect itself. Now as good exists in a thing so far as that thing is related to the appetite--and hence the aspect of goodness passes on from the desirable thing to the appetite, in so far as the appetite is called good if its object is good; so, since the true is in the intellect in so far as it is conformed to the object understood, the aspect of the true must needs pass from the intellect to the object understood, so that also the thing understood is said to be true in so far as it has some relation to the intellect.
Now a thing understood may be in relation to an intellect either essentially or accidentally. It is related essentially to an intellect on which it depends as regards its essence; but accidentally to an intellect by which it is knowable; even as we may say that a house is related essentially to the intellect of the architect, but accidentally to the intellect upon which it does not depend.
Now we do not judge of a thing by what is in it accidentally, but by what is in it essentially. Hence, everything is said to be true absolutely, in so far as it is related to the intellect from which it depends; and thus it is that artificial things are said to be true as being related to our intellect. For a house is said to be true that expresses the likeness of the form in the architect's mind; and words are said to be true so far as they are the signs of truth in the intellect. In the same way natural things are said to be true in so far as they express the likeness of the species that are in the divine mind. For a stone is called true, which possesses the nature proper to a stone, according to the preconception in the divine intellect. Thus, then, truth resides primarily in the intellect, and secondarily in things according as they are related to the intellect as their principle. Consequently there are various definitions of truth.
Augustine says (De Vera Relig. xxxvi), "Truth is that whereby is made manifest that which is;" and Hilary says (De Trin. v) that "Truth makes being clear and evident" and this pertains to truth according as it is in the intellect. As to the truth of things in so far as they are related to the intellect, we have Augustine's definition (De Vera Relig. xxxvi), "Truth is a supreme likeness without any unlikeness to a principle": also Anselm's definition (De Verit. xii), "Truth is rightness, perceptible by the mind alone"; for that is right which is in accordance with the principle; also Avicenna's definition (Metaph.
viii, 6), "The truth of each thing is a property of the essence which is immutably attached to it." The definition that "Truth is the equation of thought and thing" is applicable to it under either aspect.
Reply Obj. 1: Augustine is speaking about the truth of things, and excludes from the notion of this truth, relation to our intellect; for what is accidental is excluded from every definition.
Reply Obj. 2: The ancient philosophers held that the species of natural things did not proceed from any intellect, but were produced by chance. But as they saw that truth implies relation to intellect, they were compelled to base the truth of things on their relation to our intellect. From this, conclusions result that are inadmissible, and which the Philosopher refutes (Metaph. iv). Such, however, do not follow, if we say that the truth of things consists in their relation to the divine intellect.
Reply Obj. 3: Although the truth of our intellect is caused by the thing, yet it is not necessary that truth should be there primarily, any more than that health should be primarily in medicine, rather than in the animal: for the virtue of medicine, and not its health, is the cause of health, for here the agent is not univocal. In the same way, the being of the thing, not its truth, is the cause of truth in the intellect. Hence the Philosopher says that a thought or a word is true "from the fact that a thing is, not because a thing is true."
Whether Truth Resides Only in the Intellect Composing and Dividing?
Objection 1: It seems that truth does not reside only in the intellect composing and dividing. For the Philosopher says (De Anima iii) that as the senses are always true as regards their proper sensible objects, so is the intellect as regards "what a thing is." Now composition and division are neither in the senses nor in the intellect knowing "what a thing is." Therefore truth does not reside only in the intellect composing and dividing.
Obj. 2: Further, Isaac says in his book _On Definitions_ that truth is the equation of thought and thing. Now just as the intellect with regard to complex things can be equated to things, so also with regard to simple things; and this is true also of sense apprehending a thing as it is. Therefore truth does not reside only in the intellect composing and dividing.
_On the contrary,_ the Philosopher says (Metaph. vi) that with regard to simple things and "what a thing is," truth is "found neither in the intellect nor in things."
_I answer that,_ As stated before, truth resides, in its primary aspect, in the intellect. Now since everything is true according as it has the form proper to its nature, the intellect, in so far as it is knowing, must be true, so far as it has the likeness of the thing known, this being its form, as knowing. For this reason truth is defined by the conformity of intellect and thing; and hence to know this conformity is to know truth. But in no way can sense know this. For although sight has the likeness of a visible thing, yet it does not know the comparison which exists between the thing seen and that which itself apprehends concerning it. But the intellect can know its own conformity with the intelligible thing; yet it does not apprehend it by knowing of a thing "what a thing is." When, however, it judges that a thing corresponds to the form which it apprehends about that thing, then first it knows and expresses truth. This it does by composing and dividing: for in every proposition it either applies to, or removes from the thing signified by the subject, some form signified by the predicate: and this clearly shows that the sense is true of any thing, as is also the intellect, when it knows "what a thing is"; but it does not thereby know or affirm truth. This is in like manner the case with complex or non-complex words. Truth therefore may be in the senses, or in the intellect knowing "what a thing is," as in anything that is true; yet not as the thing known in the knower, which is implied by the word "truth"; for the perfection of the intellect is truth as known. Therefore, properly speaking, truth resides in the intellect composing and dividing; and not in the senses; nor in the intellect knowing "what a thing is."
And thus the Objections given are solved.
Whether the True and Being Are Convertible Terms?
Objection 1: It seems that the true and being are not convertible terms. For the true resides properly in the intellect, as stated (A. 1); but being is properly in things. Therefore they are not convertible.
Obj. 2: Further, that which extends to being and not-being is not convertible with being. But the true extends to being and not-being; for it is true that what is, is; and that what is not, is not.
Therefore the true and being are not convertible.
Obj. 3: Further, things which stand to each other in order of priority and posteriority seem not to be convertible. But the true appears to be prior to being; for being is not understood except under the aspect of the true. Therefore it seems they are not convertible.
_On the contrary,_ the Philosopher says (Metaph. ii) that there is the same disposition of things in being and in truth.
_I answer that,_ As good has the nature of what is desirable, so truth is related to knowledge. Now everything, in as far as it has being, so far is it knowable. Wherefore it is said in _De Anima_ iii that "the soul is in some manner all things," through the senses and the intellect. And therefore, as good is convertible with being, so is the true. But as good adds to being the notion of desirable, so the true adds relation to the intellect.
Reply Obj. 1: The true resides in things and in the intellect, as said before (A. 1). But the true that is in things is convertible with being as to substance; while the true that is in the intellect is convertible with being, as the manifestation with the manifested; for this belongs to the nature of truth, as has been said already (A.
1). It may, however, be said that being also is in things and in the intellect, as is the true; although truth is primarily in the intellect, while being is primarily in things; and this is so because truth and being differ in idea.
Reply Obj. 2: Not-being has nothing in itself whereby it can be known; yet it is known in so far as the intellect renders it knowable. Hence the true is based on being, inasmuch as not-being is a kind of logical being, apprehended, that is, by reason.
Reply Obj. 3: When it is said that being cannot be apprehended except under the notion of the true, this can be understood in two ways. In the one way so as to mean that being is not apprehended, unless the idea of the true follows apprehension of being; and this is true. In the other way, so as to mean that being cannot be apprehended unless the idea of the true be apprehended also; and this is false. But the true cannot be apprehended unless the idea of being be apprehended also; since being is included in the idea of the true. The case is the same if we compare the intelligible object with being. For being cannot be understood, unless being is intelligible. Yet being can be understood while its intelligibility is not understood. Similarly, being when understood is true, yet the true is not understood by understanding being.
Whether Good Is Logically Prior to the True?
Objection 1: It seems that good is logically prior to the true. For what is more universal is logically prior, as is evident from _Phys._ i. But the good is more universal than the true, since the true is a kind of good, namely, of the intellect. Therefore the good is logically prior to the true.
Obj. 2: Further, good is in things, but the true in the intellect composing and dividing as said above (A. 2). But that which is in things is prior to that which is in the intellect. Therefore good is logically prior to the true.
Obj. 3: Further, truth is a species of virtue, as is clear from _Ethic._ iv. But virtue is included under good; since, as Augustine says (De Lib. Arbit. ii, 19), it is a good quality of the mind.
Therefore the good is prior to the true.
_On the contrary,_ What is in more things is prior logically. But the true is in some things wherein good is not, as, for instance, in mathematics. Therefore the true is prior to good.
_I answer that,_ Although the good and the true are convertible with being, as to suppositum, yet they differ logically. And in this manner the true, speaking absolutely, is prior to good, as appears from two reasons. First, because the true is more closely related to being than is good. For the true regards being itself simply and immediately; while the nature of good follows being in so far as being is in some way perfect; for thus it is desirable. Secondly, it is evident from the fact that knowledge naturally precedes appetite. Hence, since the true regards knowledge, but the good regards the appetite, the true must be prior in idea to the good.
Reply Obj. 1: The will and the intellect mutually include one another: for the intellect understands the will, and the will wills the intellect to understand. So then, among things directed to the object of the will, are comprised also those that belong to the intellect; and conversely. Whence in the order of things desirable, good stands as the universal, and the true as the particular; whereas in the order of intelligible things the converse is the case. From the fact, then, that the true is a kind of good, it follows that the good is prior in the order of things desirable; but not that it is prior absolutely.
Reply Obj. 2: A thing is prior logically in so far as it is prior to the intellect. Now the intellect apprehends primarily being itself; secondly, it apprehends that it understands being; and thirdly, it apprehends that it desires being. Hence the idea of being is first, that of truth second, and the idea of good third, though good is in things.
Reply Obj. 3: The virtue which is called "truth" is not truth in general, but a certain kind of truth according to which man shows himself in deed and word as he really is. But truth as applied to "life" is used in a particular sense, inasmuch as a man fulfills in his life that to which he is ordained by the divine intellect, as it has been said that truth exists in other things (A. 1). Whereas the truth of "justice" is found in man as he fulfills his duty to his neighbor, as ordained by law. Hence we cannot argue from these particular truths to truth in general.
Whether God Is Truth?
Objection 1: It seems that God is not truth. For truth consists in the intellect composing and dividing. But in God there is not composition and division. Therefore in Him there is not truth.
Obj. 2: Further, truth, according to Augustine (De Vera Relig. xxxvi) is a "likeness to the principle." But in God there is no likeness to a principle. Therefore in God there is not truth.
Obj. 3: Further, whatever is said of God, is said of Him as of the first cause of all things; thus the being of God is the cause of all being; and His goodness the cause of all good. If therefore there is truth in God, all truth will be from Him. But it is true that someone sins. Therefore this will be from God; which is evidently false.
_On the contrary,_ Our Lord says, "I am the Way, the Truth, and the Life" (John 14:6).
_I answer that,_ As said above (A. 1), truth is found in the intellect according as it apprehends a thing as it is; and in things according as they have being conformable to an intellect. This is to the greatest degree found in God. For His being is not only conformed to His intellect, but it is the very act of His intellect; and His act of understanding is the measure and cause of every other being and of every other intellect, and He Himself is His own existence and act of understanding. Whence it follows not only that truth is in Him, but that He is truth itself, and the sovereign and first truth.
Reply Obj. 1: Although in the divine intellect there is neither composition nor division, yet in His simple act of intelligence He judges of all things and knows all things complex; and thus there is truth in His intellect.
Reply Obj. 2: The truth of our intellect is according to its conformity with its principle, that is to say, to the things from which it receives knowledge. The truth also of things is according to their conformity with their principle, namely, the divine intellect.
Now this cannot be said, properly 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.
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 health, and urine is called healthy, in so far as it indicates health. And although health is neither in medicine nor in urine, yet in either there is something whereby the one causes, and the other indicates health. Now we have said (A. 1) that truth resides primarily in the intellect; and secondarily in things, according as they are related to the divine intellect. If therefore we speak of truth, as it exists in the intellect, according to its proper nature, then are there many truths in many created intellects; and even in one and the
