PART I ("Prima Pars") (continued 16)

Reading edition

Reply Obj. 1: It is accidental to the universal to be abstracted from particulars, in so far as the intellect knowing it derives its knowledge from things. But if there be an intellect which does not derive its knowledge from things, the universal which it knows will not be abstracted from things, but in a measure will be pre-existing to them; either according to the order of causality, as the universal ideas of things are in the Word of God; or at least in the order of nature, as the universal ideas of things are in the angelic mind.

Reply Obj. 2: To know anything universally can be taken in two senses. In one way, on the part of the thing known, namely, that only the universal nature of the thing is known. To know a thing thus is something less perfect: for he would have but an imperfect knowledge of a man who only knew him to be an animal. In another way, on the part of the medium of such knowledge. In this way it is more perfect to know a thing in the universal; for the intellect, which by one universal medium can know each of the things which are properly contained in it, is more perfect than one which cannot.

Reply Obj. 3: The same cannot be the proper and adequate type of several things. But if it be eminent, then it can be taken as the proper type and likeness of many. Just as in man, there is a universal prudence with respect to all the acts of the virtues; which can be taken as the proper type and likeness of that prudence which in the lion leads to acts of magnanimity, and in the fox to acts of wariness; and so on of the rest. The Divine essence, on account of Its eminence, is in like fashion taken as the proper type of each thing contained therein: hence each one is likened to It according to its proper type. The same applies to the universal form which is in the mind of the angel, so that, on account of its excellence, many things can be known through it with a proper knowledge. _______________________

QUESTION 56

OF THE ANGEL'S KNOWLEDGE OF IMMATERIAL THINGS (In Three Articles)

We now inquire into the knowledge of the angels with regard to the objects known by them. We shall treat of their knowledge, first, of immaterial things, secondly of things material. Under the first heading there are three points of inquiry:

(1) Does an angel know himself?

(2) Does one angel know another?

(3) Does the angel know God by his own natural principles? _______________________

FIRST ARTICLE [I, Q. 56, Art 1]

Whether an Angel Knows Himself?

Objection 1: It would seem that an angel does not know himself. For Dionysius says that "the angels do not know their own powers" (Coel. Hier. vi). But, when the substance is known, the power is known. Therefore an angel does not know his own essence.

Obj. 2: Further, an angel is a single substance, otherwise he would not act, since acts belong to single subsistences. But nothing single is intelligible. Therefore, since the angel possesses only knowledge which is intellectual, no angel can know himself.

Obj. 3: Further, the intellect is moved by the intelligible object: because, as stated in De Anima iii, 4 understanding is a kind of passion. But nothing is moved by or is passive to itself; as appears in corporeal things. Therefore the angel cannot understand himself.

On the contrary, Augustine says (Gen. ad lit. ii) that "the angel knew himself when he was established, that is, enlightened by truth."

I answer that, As is evident from what has been previously said (Q. 14, A. 2; Q. 54, A. 2), the object is on a different footing in an immanent, and in a transient, action. In a transient action the object or matter into which the action passes is something separate from the agent, as the thing heated is from what gave it heat, and the building from the builder; whereas in an immanent action, for the action to proceed, the object must be united with the agent; just as the sensible object must be in contact with sense, in order that sense may actually perceive. And the object which is united to a faculty bears the same relation to actions of this kind as does the form which is the principle of action in other agents: for, as heat is the formal principle of heating in the fire, so is the species of the thing seen the formal principle of sight to the eye.

It must, however, be borne in mind that this image of the object exists sometimes only potentially in the knowing faculty; and then there is only knowledge in potentiality; and in order that there may be actual knowledge, it is required that the faculty of knowledge be actuated by the species. But if it always actually possesses the species, it can thereby have actual knowledge without any preceding change or reception. From this it is evident that it is not of the nature of knower, as knowing, to be moved by the object, but as knowing in potentiality. Now, for the form to be the principle of the action, it makes no difference whether it be inherent in something else, or self-subsisting; because heat would give forth heat none the less if it were self-subsisting, than it does by inhering in something else. So therefore, if in the order of intelligible beings there be any subsisting intelligible form, it will understand itself. And since an angel is immaterial, he is a subsisting form; and, consequently, he is actually intelligible. Hence it follows that he understands himself by his form, which is his substance.

Reply Obj. 1: That is the text of the old translation, which is amended in the new one, and runs thus: "furthermore they," that is to say the angels, "knew their own powers": instead of which the old translation read—"and furthermore they do not know their own powers." Although even the letter of the old translation might be kept in this respect, that the angels do not know their own power perfectly; according as it proceeds from the order of the Divine Wisdom, Which to the angels is incomprehensible.

Reply Obj. 2: We have no knowledge of single corporeal things, not because of their particularity, but on account of the matter, which is their principle of individuation. Accordingly, if there be any single things subsisting without matter, as the angels are, there is nothing to prevent them from being actually intelligible.

Reply Obj. 3: It belongs to the intellect, in so far as it is in potentiality, to be moved and to be passive. Hence this does not happen in the angelic intellect, especially as regards the fact that he understands himself. Besides the action of the intellect is not of the same nature as the action found in corporeal things, which passes into some other matter. _______________________

SECOND ARTICLE [I, Q. 56, Art. 2]

Whether One Angel Knows Another?

Objection 1: It would seem that one angel does not know another. For the Philosopher says (De Anima iii, text. 4), that if the human intellect were to have in itself any one of the sensible things, then such a nature existing within it would prevent it from apprehending external things; as likewise, if the pupil of the eye were colored with some particular color, it could not see every color. But as the human intellect is disposed for understanding corporeal things, so is the angelic mind for understanding immaterial things. Therefore, since the angelic intellect has within itself some one determinate nature from the number of such natures, it would seem that it cannot understand other natures.

Obj. 2: Further, it is stated in De Causis that "every intelligence knows what is above it, in so far as it is caused by it; and what is beneath it, in so far as it is its cause." But one angel is not the cause of another. Therefore one angel does not know another.

Obj. 3: Further, one angel cannot be known to another angel by the essence of the one knowing; because all knowledge is effected by way of a likeness. But the essence of the angel knowing is not like the essence of the angel known, except generically; as is clear from what has been said before (Q. 50, A. 4; Q. 55, A. 1, ad 3). Hence, it follows that one angel would not have a particular knowledge of another, but only a general knowledge. In like manner it cannot be said that one angel knows another by the essence of the angel known; because that whereby the intellect understands is something within the intellect; whereas the Trinity alone can penetrate the mind. Again, it cannot be said that one angel knows the other by a species; because that species would not differ from the angel understood, since each is immaterial. Therefore in no way does it appear that one angel can understand another.

Obj. 4: Further, if one angel did understand another, this would be either by an innate species; and so it would follow that, if God were now to create another angel, such an angel could not be known by the existing angels; or else he would have to be known by a species drawn from things; and so it would follow that the higher angels could not know the lower, from whom they receive nothing. Therefore in no way does it seem that one angel knows another.

On the contrary, We read in De Causis that "every intelligence knows the things which are not corrupted."

I answer that, As Augustine says (Gen. ad lit. lit. ii), such things as pre-existed from eternity in the Word of God, came forth from Him in two ways: first, into the angelic mind; and secondly, so as to subsist in their own natures. They proceeded into the angelic mind in such a way, that God impressed upon the angelic mind the images of the things which He produced in their own natural being. Now in the Word of God from eternity there existed not only the forms of corporeal things, but likewise the forms of all spiritual creatures. So in every one of these spiritual creatures, the forms of all things, both corporeal and spiritual, were impressed by the Word of God; yet so that in every angel there was impressed the form of his own species according to both its natural and its intelligible condition, so that he should subsist in the nature of his species, and understand himself by it; while the forms of other spiritual and corporeal natures were impressed in him only according to their intelligible natures, so that by such impressed species he might know corporeal and spiritual creatures.

Reply Obj. 1: The spiritual natures of the angels are distinguished from one another in a certain order, as was already observed (Q. 50, A. 4, ad 1, 2). So the nature of an angel does not hinder him from knowing the other angelic natures, since both the higher and lower bear affinity to his nature, the only difference being according to their various degrees of perfection.

Reply Obj. 2: The nature of cause and effect does not lead one angel to know another, except on account of likeness, so far as cause and effect are alike. Therefore if likeness without causality be admitted in the angels, this will suffice for one to know another.

Reply Obj. 3: One angel knows another by the species of such angel existing in his intellect, which differs from the angel whose image it is, not according to material and immaterial nature, but according to natural and intentional existence. The angel is himself a subsisting form in his natural being; but his species in the intellect of another angel is not so, for there it possesses only an intelligible existence. As the form of color on the wall has a natural existence; but, in the deferent medium, it has only intentional existence.

Reply Obj. 4: God made every creature proportionate to the universe which He determined to make. Therefore had God resolved to make more angels or more natures of things, He would have impressed more intelligible species in the angelic minds; as a builder who, if he had intended to build a larger house, would have made larger foundations. Hence, for God to add a new creature to the universe, means that He would add a new intelligible species to an angel. _______________________

THIRD ARTICLE [I, Q. 56, Art. 3]

Whether an Angel Knows God by His Own Natural Principles?

Objection 1: It would seem that the angels cannot know God by their natural principles. For Dionysius says (Div. Nom. i) that God "by His incomprehensible might is placed above all heavenly minds." Afterwards he adds that, "since He is above all substances, He is remote from all knowledge."

Obj. 2: Further, God is infinitely above the intellect of an angel. But what is infinitely beyond cannot be reached. Therefore it appears that an angel cannot know God by his natural principles.

Obj. 3: Further, it is written (1 Cor. 13:12): "We see now through a glass in a dark manner; but then face to face." From this it appears that there is a twofold knowledge of God; the one, whereby He is seen in His essence, according to which He is said to be seen face to face; the other whereby He is seen in the mirror of creatures. As was already shown (Q. 12, A. 4), an angel cannot have the former knowledge by his natural principles. Nor does vision through a mirror belong to the angels, since they do not derive their knowledge of God from sensible things, as Dionysius observes (Div. Nom. vii). Therefore the angels cannot know God by their natural powers.

On the contrary, The angels are mightier in knowledge than men. Yet men can know God through their natural principles; according to Rom. 1:19: "what is known of God is manifest in them." Therefore much more so can the angels.

I answer that, The angels can have some knowledge of God by their own principles. In evidence whereof it must be borne in mind that a thing is known in three ways: first, by the presence of its essence in the knower, as light can be seen in the eye; and so we have said that an angel knows himself—secondly, by the presence of its similitude in the power which knows it, as a stone is seen by the eye from its image being in the eye—thirdly, when the image of the object known is not drawn directly from the object itself, but from something else in which it is made to appear, as when we behold a man in a mirror.

To the first-named class that knowledge of God is likened by which He is seen through His essence; and knowledge such as this cannot accrue to any creature from its natural principles, as was said above (Q. 12, A. 4). The third class comprises the knowledge whereby we know God while we are on earth, by His likeness reflected in creatures, according to Rom. 1:20: "The invisible things of God are clearly seen, being understood by the things that are made." Hence, too, we are said to see God in a mirror. But the knowledge, whereby according to his natural principles the angel knows God, stands midway between these two; and is likened to that knowledge whereby a thing is seen through the species abstracted from it. For since God's image is impressed on the very nature of the angel in his essence, the angel knows God in as much as he is the image of God. Yet he does not behold God's essence; because no created likeness is sufficient to represent the Divine essence. Such knowledge then approaches rather to the specular kind; because the angelic nature is itself a kind of mirror representing the Divine image.

Reply Obj. 1: Dionysius is speaking of the knowledge of comprehension, as his words expressly state. In this way God is not known by any created intellect.

Reply Obj. 2: Since an angel's intellect and essence are infinitely remote from God, it follows that he cannot comprehend Him; nor can he see God's essence through his own nature. Yet it does not follow on that account that he can have no knowledge of Him at all: because, as God is infinitely remote from the angel, so the knowledge which God has of Himself is infinitely above the knowledge which an angel has of Him.

Reply Obj. 3: The knowledge which an angel has of God is midway between these two kinds of knowledge; nevertheless it approaches more to one of them, as was said above. _______________________

QUESTION 57

OF THE ANGEL'S KNOWLEDGE OF MATERIAL THINGS (In Five Articles)

We next investigate the material objects which are known by the angels. Under this heading there are five points of inquiry:

(1) Whether the angels know the natures of material things?

(2) Whether they know single things?

(3) Whether they know the future?

(4) Whether they know secret thoughts?

(5) Whether they know all mysteries of grace? _______________________

FIRST ARTICLE [I, Q. 57, Art. 1]

Whether the Angels Know Material Things?

Objection 1: It would seem that the angels do not know material things. For the object understood is the perfection of him who understands it. But material things cannot be the perfections of angels, since they are beneath them. Therefore the angels do not know material things.

Obj. 2: Further, intellectual vision is only of such things as exist within the soul by their essence, as is said in the gloss [*On 2 Cor. 12:2, taken from Augustine (Gen. ad lit. xii. 28)]. But the material things cannot enter by their essence into man's soul, nor into the angel's mind. Therefore they cannot be known by intellectual vision, but only by imaginary vision, whereby the images of bodies are apprehended, and by sensible vision, which regards bodies in themselves. Now there is neither imaginary nor sensible vision in the angels, but only intellectual. Therefore the angels cannot know material things.

Obj. 3: Further, material things are not actually intelligible, but are knowable by apprehension of sense and of imagination, which does not exist in angels. Therefore angels do not know material things.

On the contrary, Whatever the lower power can do, the higher can do likewise. But man's intellect, which in the order of nature is inferior to the angel's, can know material things. Therefore much more can the mind of an angel.

I answer that, The established order of things is for the higher beings to be more perfect than the lower; and for whatever is contained deficiently, partially, and in manifold manner in the lower beings, to be contained in the higher eminently, and in a certain degree of fulness and simplicity. Therefore, in God, as in the highest source of things, all things pre-exist supersubstantially in respect of His simple Being itself, as Dionysius says (Div. Nom. 1). But among other creatures the angels are nearest to God, and resemble Him most; hence they share more fully and more perfectly in the Divine goodness, as Dionysius says (Coel. Hier. iv). Consequently, all material things pre-exist in the angels more simply and less materially even than in themselves, yet in a more manifold manner and less perfectly than in God.

Now whatever exists in any subject, is contained in it after the manner of such subject. But the angels are intellectual beings of their own nature. Therefore, as God knows material things by His essence, so do the angels know them, forasmuch as they are in the angels by their intelligible species.

Reply Obj. 1: The thing understood is the perfection of the one who understands, by reason of the intelligible species which he has in his intellect. And thus the intelligible species which are in the intellect of an angel are perfections and acts in regard to that intellect.

Reply Obj. 2: Sense does not apprehend the essences of things, but only their outward accidents. In like manner neither does the imagination; for it apprehends only the images of bodies. The intellect alone apprehends the essences of things. Hence it is said (De Anima iii, text. 26) that the object of the intellect is "what a thing is," regarding which it does not err; as neither does sense regarding its proper sensible object. So therefore the essences of material things are in the intellect of man and angels, as the thing understood is in him who understands, and not according to their real natures. But some things are in an intellect or in the soul according to both natures; and in either case there is intellectual vision.

Reply Obj. 3: If an angel were to draw his knowledge of material things from the material things themselves, he would require to make them actually intelligible by a process of abstraction. But he does not derive his knowledge of them from the material things themselves; he has knowledge of material things by actually intelligible species of things, which species are connatural to him; just as our intellect has, by species which it makes intelligible by abstraction. _______________________

SECOND ARTICLE [I, Q. 57, Art. 2]

Whether an Angel Knows Singulars?

Objection 1: It would seem that angels do not know singulars. For the Philosopher says (Poster. i, text. 22): "The sense has for its object singulars, but the intellect, universals." Now, in the angels there is no power of understanding save the intellectual power, as is evident from what was said above (Q. 54, A. 5). Consequently they do not know singulars.

Obj. 2: Further, all knowledge comes about by some assimilation of the knower to the object known. But it is not possible for any assimilation to exist between an angel and a singular object, in so far as it is singular; because, as was observed above (Q. 50, A. 2), an angel is immaterial, while matter is the principle of singularity. Therefore the angel cannot know singulars.

Obj. 3: Further, if an angel does know singulars, it is either by singular or by universal species. It is not by singular species; because in this way he would require to have an infinite number of species. Nor is it by universal species; since the universal is not the sufficient principle for knowing the singular as such, because singular things are not known in the universal except potentially. Therefore the angel does not know singulars.

On the contrary, No one can guard what he does not know. But angels guard individual men, according to Ps. 90:11: "He hath given His angels charge over Thee." Consequently the angels know singulars.

I answer that, Some have denied to the angels all knowledge of singulars. In the first place this derogates from the Catholic faith, which asserts that these lower things are administered by angels, according to Heb. 1:14: "They are all ministering spirits." Now, if they had no knowledge of singulars, they could exercise no provision over what is going on in this world; since acts belong to individuals: and this is against the text of Eccles. 5:5: "Say not before the angel: There is no providence." Secondly, it is also contrary to the teachings of philosophy, according to which the angels are stated to be the movers of the heavenly spheres, and to move them according to their knowledge and will.

Consequently others have said that the angel possesses knowledge of singulars, but in their universal causes, to which all particular effects are reduced; as if the astronomer were to foretell a coming eclipse from the dispositions of the movements of the heavens. This opinion does not escape the aforesaid implications; because, to know a singular, merely in its universal causes, is not to know it as singular, that is, as it exists here and now. The astronomer, knowing from computation of the heavenly movements that an eclipse is about to happen, knows it in the universal; yet he does not know it as taking place now, except by the senses. But administration, providence and movement are of singulars, as they are here and now existing.

Therefore, it must be said differently, that, as man by his various powers of knowledge knows all classes of things, apprehending universals and immaterial things by his intellect, and things singular and corporeal by the senses, so an angel knows both by his one mental power. For the order of things runs in this way, that the higher a thing is, so much the more is its power united and far-reaching: thus in man himself it is manifest that the common sense which is higher than the proper sense, although it is but one faculty, knows everything apprehended by the five outward senses, and some other things which no outer sense knows; for example, the difference between white and sweet. The same is to be observed in other cases. Accordingly, since an angel is above man in the order of nature, it is unreasonable to say that a man knows by any one of his powers something which an angel by his one faculty of knowledge, namely, the intellect, does not know. Hence Aristotle pronounces it ridiculous to say that a discord, which is known to us, should be unknown to God (De Anima i, text. 80; Metaph. text. 15).

The manner in which an angel knows singular things can be considered from this, that, as things proceed from God in order that they may subsist in their own natures, so likewise they proceed in order that they may exist in the angelic mind. Now it is clear that there comes forth from God not only whatever belongs to their universal nature, but likewise all that goes to make up their principles of individuation; since He is the cause of the entire substance of the thing, as to both its matter and its form. And for as much as He causes, does He know; for His knowledge is the cause of a thing, as was shown above (Q. 14, A. 8). Therefore as by His essence, by which He causes all things, God is the likeness of all things, and knows all things, not only as to their universal natures, but also as to their singularity; so through the species imparted to them do the angels know things, not only as to their universal nature, but likewise in their individual conditions, in so far as they are the manifold representations of that one simple essence.

Reply Obj. 1: The Philosopher is speaking of our intellect, which apprehends only by a process of abstraction; and by such abstraction from material conditions the thing abstracted becomes a universal. Such a manner of understanding is not in keeping with the nature of the angels, as was said above (Q. 55, A. 2, A. 3 ad 1), and consequently there is no comparison.

Reply Obj. 2: It is not according to their nature that the angels are likened to material things, as one thing resembles another by agreement in genus, species, or accident; but as the higher bears resemblance to the lower, as the sun does to fire. Even in this way there is in God a resemblance of all things, as to both matter and form, in so far as there pre-exists in Him as in its cause whatever is to be found in things. For the same reason, the species in the angel's intellect, which are images drawn from the Divine essence, are the images of things not only as to their form, but also as to their matter.

Reply Obj. 3: Angels know singulars by universal forms, which nevertheless are the images of things both as to their universal, and as to their individuating principles. How many things can be known by the same species, has been already stated above (Q. 55, A. 3, ad 3). _______________________

THIRD ARTICLE [I, Q. 57, Art. 3]

Whether Angels Know the Future?

Objection 1: It would seem that the angels know future events. For angels are mightier in knowledge than men. But some men know many future events. Therefore much more do the angels.

Obj. 2: Further, the present and the future are differences of time. But the angel's intellect is above time; because, as is said in De Causis, "an intelligence keeps pace with eternity," that is, aeviternity. Therefore, to the angel's mind, past and future are not different, but he knows each indifferently.

Obj. 3: Further, the angel does not understand by species derived from things, but by innate universal species. But universal species refer equally to present, past, and future. Therefore it appears that the angels know indifferently things past, present, and future.

Obj. 4: Further, as a thing is spoken of as distant by reason of time, so is it by reason of place. But angels know things which are distant according to place. Therefore they likewise know things distant according to future time.

On the contrary, Whatever is the exclusive sign of the Divinity, does not belong to the angels. But to know future events is the exclusive sign of the Divinity, according to Isa. 41:23: "Show the things that are to come hereafter, and we shall know that ye are gods." Therefore the angels do not know future events.

I answer that, The future can be known in two ways. First, it can be known in its cause. And thus, future events which proceed necessarily from their causes, are known with sure knowledge; as that the sun will rise tomorrow. But events which proceed from their causes in the majority of cases, are not known for certain, but conjecturally; thus the doctor knows beforehand the health of the patient. This manner of knowing future events exists in the angels, and by so much the more than it does in us, as they understand the causes of things both more universally and more perfectly; thus doctors who penetrate more deeply into the causes of an ailment can pronounce a surer verdict on the future issue thereof. But events which proceed from their causes in the minority of cases are quite unknown; such as casual and chance events.

In another way future events are known in themselves. To know the future in this way belongs to God alone; and not merely to know those events which happen of necessity, or in the majority of cases, but even casual and chance events; for God sees all things in His eternity, which, being simple, is present to all time, and embraces all time. And therefore God's one glance is cast over all things which happen in all time as present before Him; and He beholds all things as they are in themselves, as was said before when dealing with God's knowledge (Q. 14, A. 13). But the mind of an angel, and every created intellect, fall far short of God's eternity; hence the future as it is in itself cannot be known by any created intellect.

Reply Obj. 1: Men cannot know future things except in their causes, or by God's revelation. The angels know the future in the same way, but much more distinctly.

Reply Obj. 2: Although the angel's intellect is above that time according to which corporeal movements are reckoned, yet there is a time in his mind according to the succession of intelligible concepts; of which Augustine says (Gen. ad lit. viii) that "God moves the spiritual creature according to time." And thus, since there is succession in the angel's intellect, not all things that happen through all time, are present to the angelic mind.

Reply Obj. 3: Although the species in the intellect of an angel, in so far as they are species, refer equally to things present, past, and future; nevertheless the present, past, and future; nevertheless the present, past, and future do not bear the same relations to the species. Present things have a nature according to which they resemble the species in the mind of an angel: and so they can be known thereby. Things which are yet to come have not yet a nature whereby they are likened to such species; consequently, they cannot be known by those species.

Reply Obj. 4: Things distant according to place are already existing in nature; and share in some species, whose image is in the angel; whereas this is not true of future things, as has been stated. Consequently there is no comparison. _______________________

FOURTH ARTICLE [I, Q. 57, Art. 4]

Whether Angels Know Secret Thoughts?

Objection 1: It would seem that the angels know secret thoughts. For Gregory (Moral. xviii), explaining Job 28:17: "Gold or crystal cannot equal it," says that "then," namely in the bliss of those rising from the dead, "one shall be as evident to another as he is to himself, and when once the mind of each is seen, his conscience will at the same time be penetrated." But those who rise shall be like the angels, as is stated (Matt. 22:30). Therefore an angel can see what is in another's conscience.

Obj. 2: Further, intelligible species bear the same relation to the intellect as shapes do to bodies. But when the body is seen its shape is seen. Therefore, when an intellectual substance is seen, the intelligible species within it is also seen. Consequently, when one angel beholds another, or even a soul, it seems that he can see the thoughts of both.

Obj. 3: Further, the ideas of our intellect resemble the angel more than do the images in our imagination; because the former are actually understood, while the latter are understood only potentially. But the images in our imagination can be known by an angel as corporeal things are known: because the imagination is a corporeal faculty. Therefore it seems that an angel can know the thoughts of the intellect.

On the contrary, What is proper to God does not belong to the angels. But it is proper to God to read the secrets of hearts, according to Jer. 17:9: "The heart is perverse above all things, and unsearchable; who can know it? I am the Lord, Who search the heart." Therefore angels do not know the secrets of hearts.

I answer that, A secret thought can be known in two ways: first, in its effect. In this way it can be known not only by an angel, but also by man; and with so much the greater subtlety according as the effect is the more hidden. For thought is sometimes discovered not merely by outward act, but also by change of countenance; and doctors can tell some passions of the soul by the mere pulse. Much more then can angels, or even demons, the more deeply they penetrate those occult bodily modifications. Hence Augustine says (De divin. daemon.) that demons "sometimes with the greatest faculty learn man's dispositions, not only when expressed by speech, but even when conceived in thought, when the soul expresses them by certain signs in the body"; although (Retract. ii, 30) he says "it cannot be asserted how this is done."

In another way thoughts can be known as they are in the mind, and affections as they are in the will: and thus God alone can know the thoughts of hearts and affections of wills. The reason of this is, because the rational creature is subject to God only, and He alone can work in it Who is its principal object and last end: this will be developed later (Q. 63, A. 1; Q. 105, A. 5). Consequently all that is in the will, and all things that depend only on the will, are known to God alone. Now it is evident that it depends entirely on the will for anyone actually to consider anything; because a man who has a habit of knowledge, or any intelligible species, uses them at will. Hence the Apostle says (1 Cor. 2:11): "For what man knoweth the things of a man, but the spirit of a man that is in him?"

Reply Obj. 1: In the present life one man's thought is not known by another owing to a twofold hindrance; namely, on account of the grossness of the body, and because the will shuts up its secrets. The first obstacle will be removed at the Resurrection, and does not exist at all in the angels; while the second will remain, and is in the angels now. Nevertheless the brightness of the body will show forth the quality of the soul; as to its amount of grace and of glory. In this way one will be able to see the mind of another.

Reply Obj. 2: Although one angel sees the intelligible species of another, by the fact that the species are proportioned to the rank of these substances according to greater or lesser universality, yet it does not follow that one knows how far another makes use of them by actual consideration.

Reply Obj. 3: The appetite of the brute does not control its act, but follows the impression of some other corporeal or spiritual cause. Since, therefore, the angels know corporeal things and their dispositions, they can thereby know what is passing in the appetite or in the imaginative apprehension of the brute beasts, and even of man, in so far as the sensitive appetite sometimes, through following some bodily impression, influences his conduct, as always happens in brutes. Yet the angels do not necessarily know the movement of the sensitive appetite and the imaginative apprehension of man in so far as these are moved by the will and reason; because, even the lower part of the soul has some share of reason, as obeying its ruler, as is said in Ethics iii, 12. But it does not follow that, if the angel knows what is passing through man's sensitive appetite or imagination, he knows what is in the thought or will: because the intellect or will is not subject to the sensitive appetite or the imagination, but can make various uses of them. _______________________

FIFTH ARTICLE [I, Q. 57, Art. 5]

Whether the Angels Know the Mysteries of Grace?

Objection 1: It would seem that the angels know mysteries of grace. For, the mystery of the Incarnation is the most excellent of all mysteries. But the angels knew of it from the beginning; for Augustine says (Gen. ad lit. v, 19): "This mystery was hidden in God through the ages, yet so that it was known to the princes and powers in heavenly places." And the Apostle says (1 Tim. 3:16): "That great mystery of godliness appeared unto angels*." [*Vulg.: 'Great is the mystery of godliness, which . . . appeared unto angels.'] Therefore the angels know the mysteries of grace.

Obj. 2: Further, the reasons of all mysteries of grace are contained in the Divine wisdom. But the angels behold God's wisdom, which is His essence. Therefore they know the mysteries of grace.

Obj. 3: Further, the prophets are enlightened by the angels, as is clear from Dionysius (Coel. Hier. iv). But the prophets knew mysteries of grace; for it is said (Amos 3:7): "For the Lord God doth nothing without revealing His secret to His servants the prophets." Therefore angels know the mysteries of grace.

On the contrary, No one learns what he knows already. Yet even the highest angels seek out and learn mysteries of grace. For it is stated (Coel. Hier. vii) that "Sacred Scripture describes some heavenly essences as questioning Jesus, and learning from Him the knowledge of His Divine work for us; and Jesus as teaching them directly": as is evident in Isa. 63:1, where, on the angels asking, "Who is he who cometh up from Edom?" Jesus answered, "It is I, Who speak justice." Therefore the angels do not know mysteries of grace.

I answer that, There is a twofold knowledge in the angel. The first is his natural knowledge, according to which he knows things both by his essence, and by innate species. By such knowledge the angels cannot know mysteries of grace. For these mysteries depend upon the pure will of God: and if an angel cannot learn the thoughts of another angel, which depend upon the will of such angel, much less can he ascertain what depends entirely upon God's will. The Apostle reasons in this fashion (1 Cor. 2:11): "No one knoweth the things of a man [*Vulg.: 'What man knoweth the things of a man, but . . . ?'], but the spirit of a man that is in him." So, "the things also that are of God no man knoweth but the Spirit of God."

There is another knowledge of the angels, which renders them happy; it is the knowledge whereby they see the Word, and things in the Word. By such vision they know mysteries of grace, but not all mysteries: nor do they all know them equally; but just as God wills them to learn by revelation; as the Apostle says (1 Cor. 2:10): "But to us God hath revealed them through His Spirit"; yet so that the higher angels beholding the Divine wisdom more clearly, learn more and deeper mysteries in the vision of God, which mysteries they communicate to the lower angels by enlightening them. Some of these mysteries they knew from the very beginning of their creation; others they are taught afterwards, as befits their ministrations.

Reply Obj. 1: One can speak in two ways of the mystery of the Incarnation. First of all, in general; and in this way it was revealed to all from the commencement of their beatitude. The reason of this is, that this is a kind of general principle to which all their duties are ordered. For "all are [*Vulg.: 'Are they not all.'] ministering spirits, sent to minister for them who shall receive the inheritance of salvation" (Heb. 1:14); and this is brought about by the mystery of the Incarnation. Hence it was necessary for all of them to be instructed in this mystery from the very beginning.

We can speak of the mystery of the Incarnation in another way, as to its special conditions. Thus not all the angels were instructed on all points from the beginning; even the higher angels learned these afterwards, as appears from the passage of Dionysius already quoted.

Reply Obj. 2: Although the angels in bliss behold the Divine wisdom, yet they do not comprehend it. So it is not necessary for them to know everything hidden in it.

Reply Obj. 3: Whatever the prophets knew by revelation of the mysteries of grace, was revealed in a more excellent way to the angels. And although God revealed in general to the prophets what He was one day to do regarding the salvation of the human race, still the apostles knew some particulars of the same, which the prophets did not know. Thus we read (Eph. 3:4, 5): "As you reading, may understand my knowledge in the mystery of Christ, which in other generations was not known to the sons of men, as it is now revealed to His holy apostles." Among the prophets also, the later ones knew what the former did not know; according to Ps. 118:100: "I have had understanding above ancients," and Gregory says: "The knowledge of Divine things increased as time went on" (Hom. xvi in Ezech.). _______________________

QUESTION 58

OF THE MODE OF ANGELIC KNOWLEDGE (In Seven Articles)

After the foregoing we have now to treat of the mode of the angelic knowledge, concerning which there are seven points of inquiry:

(1) Whether the angel's intellect be sometimes in potentiality, and sometimes in act?

(2) Whether the angel can understand many things at the same time?

(3) Whether the angel's knowledge is discursive?

(4) Whether he understands by composing and dividing?

(5) Whether there can be error in the angel's intellect?

(6) Whether his knowledge can be styled as morning and evening?

(7) Whether the morning and evening knowledge are the same, or do they differ? _______________________

FIRST ARTICLE [I, Q. 58, Art. 1]

Whether the Angel's Intellect Is Sometimes in Potentiality, Sometimes in Act?

Objection 1: It would seem that the angel's intellect is sometimes in potentiality and sometimes in act. For movement is the act of what is in potentiality, as stated in Phys. iii, 6. But the angels' minds are moved by understanding, as Dionysius says (Div. Nom. iv). Therefore the angelic minds are sometimes in potentiality.

Obj. 2: Further, since desire is of a thing not possessed but possible to have, whoever desires to know anything is in potentiality thereto. But it is said (1 Pet. 1:12): "On Whom the angels desire to look." Therefore the angel's intellect is sometimes in potentiality.

Obj. 3: Further, in the book De Causis it is stated that "an intelligence understands according to the mode of its substance." But the angel's intelligence has some admixture of potentiality. Therefore it sometimes understands potentially.

On the contrary, Augustine says (Gen. ad lit. ii): "Since the angels were created, in the eternity of the Word, they enjoy holy and devout contemplation." Now a contemplating intellect is not in potentiality, but in act. Therefore the intellect of an angel is not in potentiality.

I answer that, As the Philosopher states (De Anima iii, text. 8; Phys. viii, 32), the intellect is in potentiality in two ways; first, "as before learning or discovering," that is, before it has the habit of knowledge; secondly, as "when it possesses the habit of knowledge, but does not actually consider." In the first way an angel's intellect is never in potentiality with regard to the things to which his natural knowledge extends. For, as the higher, namely, the heavenly, bodies have no potentiality to existence, which is not fully actuated, in the same way the heavenly intellects, the angels, have no intelligible potentiality which is not fully completed by connatural intelligible species. But with regard to things divinely revealed to them, there is nothing to hinder them from being in potentiality: because even the heavenly bodies are at times in potentiality to being enlightened by the sun.

In the second way an angel's intellect can be in potentiality with regard to things learnt by natural knowledge; for he is not always actually considering everything that he knows by natural knowledge. But as to the knowledge of the Word, and of the things he beholds in the Word, he is never in this way in potentiality; because he is always actually beholding the Word, and the things he sees in the Word. For the bliss of the angels consists in such vision; and beatitude does not consist in habit, but in act, as the Philosopher says (Ethic. i, 8).

Reply Obj. 1: Movement is taken there not as the act of something imperfect, that is, of something existing in potentiality, but as the act of something perfect, that is, of one actually existing. In this way understanding and feeling are termed movements, as stated in De Anima iii, text. 28.

Reply Obj. 2: Such desire on the part of the angels does not exclude the object desired, but weariness thereof. Or they are said to desire the vision of God with regard to fresh revelations, which they receive from God to fit them for the tasks which they have to perform.

Reply Obj. 3: In the angel's substance there is no potentiality divested of act. In the same way, the angel's intellect is never so in potentiality as to be without act. _______________________

SECOND ARTICLE [I, Q. 58, Art. 2]

Whether an Angel Can Understand Many Things at the Same Time?

Objection 1: It would seem that an angel cannot understand many things at the same time. For the Philosopher says (Topic. ii, 4) that "it may happen that we know many things, but understand only one."

Obj. 2: Further, nothing is understood unless the intellect be informed by an intelligible species; just at the body is formed by shape. But one body cannot be formed into many shapes. Therefore neither can one intellect simultaneously understand various intelligible things.

Obj. 3: Further, to understand is a kind of movement. But no movement terminates in various terms. Therefore many things cannot be understood altogether.

On the contrary, Augustine says (Gen. ad lit. iv, 32): "The spiritual faculty of the angelic mind comprehends most easily at the same time all things that it wills."

I answer that, As unity of term is requisite for unity of movement, so is unity of object required for unity of operation. Now it happens that several things may be taken as several or as one; like the parts of a continuous whole. For if each of the parts be considered severally they are many: consequently neither by sense nor by intellect are they grasped by one operation, nor all at once. In another way they are taken as forming one in the whole; and so they are grasped both by sense and intellect all at once and by one operation; as long as the entire continuous whole is considered, as is stated in De Anima iii, text. 23. In this way our intellect understands together both the subject and the predicate, as forming parts of one proposition; and also two things compared together, according as they agree in one point of comparison. From this it is evident that many things, in so far as they are distinct, cannot be understood at once; but in so far as they are comprised under one intelligible concept, they can be understood together. Now everything is actually intelligible according as its image is in the intellect. All things, then, which can be known by one intelligible species, are known as one intelligible object, and therefore are understood simultaneously. But things known by various intelligible species, are apprehended as different intelligible objects.

Consequently, by such knowledge as the angels have of things through the Word, they know all things under one intelligible species, which is the Divine essence. Therefore, as regards such knowledge, they know all things at once: just as in heaven "our thoughts will not be fleeting, going and returning from one thing to another, but we shall survey all our knowledge at the same time by one glance," as Augustine says (De Trin. xv, 16). But by that knowledge wherewith the angels know things by innate species, they can at one time know all things which can be comprised under one species; but not such as are under various species.

Reply Obj. 1: To understand many things as one, is, so to speak, to understand one thing.

Reply Obj. 2: The intellect is informed by the intelligible species which it has within it. So it can behold at the same time many intelligible objects under one species; as one body can by one shape be likened to many bodies.

To the third objection the answer is the same as the first. _______________________

THIRD ARTICLE [I, Q. 58, Art. 3]

Whether an Angel's Knowledge Is Discursive?

Objection 1: It would seem that the knowledge of an angel is discursive. For the discursive movement of the mind comes from one thing being known through another. But the angels know one thing through another; for they know creatures through the Word. Therefore the intellect of an angel knows by discursive method.

Obj. 2: Further, whatever a lower power can do, the higher can do. But the human intellect can syllogize, and know causes in effects; all of which is the discursive method. Therefore the intellect of the angel, which is higher in the order of nature, can with greater reason do this.

Obj. 3: Further, Isidore (De sum. bono i, 10) says that "demons learn more things by experience." But experimental knowledge is discursive: for, "one experience comes of many remembrances, and one universal from many experiences," as Aristotle observes (Poster. ii; Metaph. vii). Therefore an angel's knowledge is discursive.

On the contrary, Dionysius says (Div. Nom. vii) that the "angels do not acquire Divine knowledge from separate discourses, nor are they led to something particular from something common."

I answer that, As has often been stated (A. 1; Q. 55, A. 1), the angels hold that grade among spiritual substances which the heavenly bodies hold among corporeal substances: for Dionysius calls them "heavenly minds" (loc. cit.). Now, the difference between heavenly and earthly bodies is this, that earthly bodies obtain their last perfection by chance and movement: while the heavenly bodies have their last perfection at once from their very nature. So, likewise, the lower, namely, the human, intellects obtain their perfection in the knowledge of truth by a kind of movement and discursive intellectual operation; that is to say, as they advance from one known thing to another. But, if from the knowledge of a known principle they were straightway to perceive as known all its consequent conclusions, then there would be no discursive process at all. Such is the condition of the angels, because in the truths which they know naturally, they at once behold all things whatsoever that can be known in them.

Therefore they are called "intellectual beings": because even with ourselves the things which are instantly grasped by the mind are said to be understood [intelligi]; hence "intellect" is defined as the habit of first principles. But human souls which acquire knowledge of truth by the discursive method are called "rational"; and this comes of the feebleness of their intellectual light. For if they possessed the fulness of intellectual light, like the angels, then in the first aspect of principles they would at once comprehend their whole range, by perceiving whatever could be reasoned out from them.

Reply Obj. 1: Discursion expresses movement of a kind. Now all movement is from something before to something after. Hence discursive knowledge comes about according as from something previously known one attains to the knowledge of what is afterwards known, and which was previously unknown. But if in the thing perceived something else be seen at the same time, as an object and its image are seen simultaneously in a mirror, it is not discursive knowledge. And in this way the angels know things in the Word.

Reply Obj. 2: The angels can syllogize, in the sense of knowing a syllogism; and they see effects in causes, and causes in effects: yet they do not acquire knowledge of an unknown truth in this way, by syllogizing from causes to effect, or from effect to cause.

Reply Obj. 3: Experience is affirmed of angels and demons simply by way of similitude, forasmuch as they know sensible things which are present, yet without any discursion withal. _______________________

FOURTH ARTICLE [I, Q. 58, Art. 4]

Whether the Angels Understand by Composing and Dividing?

Objection 1: It would seem that the angels understand by composing and dividing. For, where there is multiplicity of things understood, there is composition of the same, as is said in De Anima iii, text. 21. But there is a multitude of things understood in the angelic mind; because angels apprehend different things by various species, and not all at one time. Therefore there is composition and division in the angel's mind.

Obj. 2: Further, negation is far more remote from affirmation than any two opposite natures are; because the first of distinctions is that of affirmation and negation. But the angel knows certain distant natures not by one, but by diverse species, as is evident from what was said (A. 2). Therefore he must know affirmation and negation by diverse species. And so it seems that he understands by composing and dividing.

Obj. 3: Further, speech is a sign of the intellect. But in speaking to men, angels use affirmative and negative expressions, which are signs of composition and of division in the intellect; as is manifest from many passages of Sacred Scripture. Therefore it seems that the angel understands by composing and dividing.

On the contrary, Dionysius says (Div. Nom. vii) that "the intellectual power of the angel shines forth with the clear simplicity of divine concepts." But a simple intelligence is without composition and division. Therefore the angel understands without composition or division.

I answer that, As in the intellect, when reasoning, the conclusion is compared with the principle, so in the intellect composing and dividing, the predicate is compared with the subject. For if our intellect were to see at once the truth of the conclusion in the principle, it would never understand by discursion and reasoning. In like manner, if the intellect in apprehending the quiddity of the subject were at once to have knowledge of all that can be attributed to, or removed from, the subject, it would never understand by composing and dividing, but only by understanding the essence. Thus it is evident that for the self-same reason our intellect understands by discursion, and by composing and dividing, namely, that in the first apprehension of anything newly apprehended it does not at once grasp all that is virtually contained in it. And this comes from the weakness of the intellectual light within us, as has been said (A. 3). Hence, since the intellectual light is perfect in the angel, for he is a pure and most clear mirror, as Dionysius says (Div. Nom. iv), it follows that as the angel does not understand by reasoning, so neither does he by composing and dividing.

Nevertheless, he understands the composition and the division of enunciations, just as he apprehends the reasoning of syllogisms: for he understands simply, such things as are composite, things movable immovably, and material things immaterially.

Reply Obj. 1: Not every multitude of things understood causes composition, but a multitude of such things understood that one of them is attributed to, or denied of, another. When an angel apprehends the nature of anything, he at the same time understands whatever can be either attributed to it, or denied of it. Hence, in apprehending a nature, he by one simple perception grasps all that we can learn by composing and dividing.

Reply Obj. 2: The various natures of things differ less as to their mode of existing than do affirmation and negation. Yet, as to the way in which they are known, affirmation and negation have something more in common; because directly the truth of an affirmation is known, the falsehood of the opposite negation is known also.

Reply Obj. 3: The fact that angels use affirmative and negative forms of speech, shows that they know both composition and division: yet not that they know by composing and dividing, but by knowing simply the nature of a thing. _______________________

FIFTH ARTICLE [I, Q. 58, Art. 5]

Whether There Can Be Falsehood in the Intellect of an Angel?

Objection 1: It would seem that there can be falsehood in the angel's intellect. For perversity appertains to falsehood. But, as Dionysius says (Div. Nom. iv), there is "a perverted fancy" in the demons. Therefore it seems that there can be falsehood in the intellect of the angels.

Obj. 2: Further, nescience is the cause of estimating falsely. But, as Dionysius says (Eccl. Hier. vi), there can be nescience in the angels. Therefore it seems there can be falsehood in them.

Obj. 3: Further, everything which falls short of the truth of wisdom, and which has a depraved reason, has falsehood or error in its intellect. But Dionysius (Div. Nom. vii) affirms this of the demons. Therefore it seems that there can be error in the minds of the angels.

On the contrary, The Philosopher says (De Anima iii, text. 41) that "the intelligence is always true." Augustine likewise says (QQ. 83, qu. 32) that "nothing but what is true can be the object of intelligence" Therefore there can be neither deception nor falsehood in the angel's knowledge.

I answer that, The truth of this question depends partly upon what has gone before. For it has been said (A. 4) that an angel understands not by composing and dividing, but by understanding what a thing is. Now the intellect is always true as regards what a thing is, just as the sense regarding its proper object, as is said in De Anima iii, text. 26. But by accident, deception and falsehood creep in, when we understand the essence of a thing by some kind of composition, and this happens either when we take the definition of one thing for another, or when the parts of a definition do not hang together, as if we were to accept as the definition of some creature, "a four-footed flying beast," for there is no such animal. And this comes about in things composite, the definition of which is drawn from diverse elements, one of which is as matter to the other. But there is no room for error in understanding simple quiddities, as is stated in Metaph. ix, text. 22; for either they are not grasped at all, and so we know nothing respecting them; or else they are known precisely as they exist.

So therefore, no falsehood, error, or deception can exist of itself in the mind of any angel; yet it does so happen accidentally; but very differently from the way it befalls us. For we sometimes get at the quiddity of a thing by a composing and dividing process, as when, by division and demonstration, we seek out the truth of a definition. Such is not the method of the angels; but through the (knowledge of the) essence of a thing they know everything that can be said regarding it. Now it is quite evident that the quiddity of a thing can be a source of knowledge with regard to everything belonging to such thing, or excluded from it; but not of what may be dependent on God's supernatural ordinance. Consequently, owing to their upright will, from their knowing the nature of every creature, the good angels form no judgments as to the nature of the qualities therein, save under the Divine ordinance; hence there can be no error or falsehood in them. But since the minds of demons are utterly perverted from the Divine wisdom, they at times form their opinions of things simply according to the natural conditions of the same. Nor are they ever deceived as to the natural properties of anything; but they can be misled with regard to supernatural matters; for example, on seeing a dead man, they may suppose that he will not rise again, or, on beholding Christ, they may judge Him not to be God.

From all this the answers to the objections of both sides of the question are evident. For the perversity of the demons comes of their not being subject to the Divine wisdom; while nescience is in the angels as regards things knowable, not naturally but supernaturally. It is, furthermore, evident that their understanding of what a thing is, is always true, save accidentally, according as it is, in an undue manner, referred to some composition or division. _______________________

SIXTH ARTICLE [I, Q. 58, A. 6]

Whether There Is a "Morning" and an "Evening" Knowledge in the Angels?

Objection 1: It would seem that there is neither an evening nor a morning knowledge in the angels; because evening and morning have an admixture of darkness. But there is no darkness in the knowledge of an angel; since there is no error nor falsehood. Therefore the angelic knowledge ought not to be termed morning and evening knowledge.

Obj. 2: Further, between evening and morning the night intervenes; while noonday falls between morning and evening. Consequently, if there be a morning and an evening knowledge in the angels, for the same reason it appears that there ought to be a noonday and a night knowledge.

Obj. 3: Further, knowledge is diversified according to the difference of the objects known: hence the Philosopher says (De Anima iii, text. 38), "The sciences are divided just as things are." But there is a threefold existence of things: to wit, in the Word; in their own natures; and in the angelic knowledge, as Augustine observes (Gen. ad lit. ii, 8). If, therefore, a morning and an evening knowledge be admitted in the angels, because of the existence of things in the Word, and in their own nature, then there ought to be admitted a third class of knowledge, on account of the existence of things in the angelic mind.

On the contrary, Augustine (Gen. ad lit. iv, 22, 31; De Civ. Dei xii, 7, 20) divides the knowledge of the angels into morning and evening knowledge.

I answer that, The expression "morning" and "evening" knowledge was devised by Augustine; who interprets the six days wherein God made all things, not as ordinary days measured by the solar circuit, since the sun was only made on the fourth day, but as one day, namely, the day of angelic knowledge as directed to six classes of things. As in the ordinary day, morning is the beginning, and evening the close of day, so, their knowledge of the primordial being of things is called morning knowledge; and this is according as things exist in the Word. But their knowledge of the very being of the thing created, as it stands in its own nature, is termed evening knowledge; because the being of things flows from the Word, as from a kind of primordial principle; and this flow is terminated in the being which they have in themselves.

Reply Obj. 1: Evening and morning knowledge in the angelic knowledge are not taken as compared to an admixture of darkness, but as compared to beginning and end. Or else it can be said, as Augustine puts it (Gen. ad lit. iv, 23), that there is nothing to prevent us from calling something light in comparison with one thing, and darkness with respect to another. In the same way the life of the faithful and the just is called light in comparison with the wicked, according to Eph. 5:8: "You were heretofore darkness; but now, light in the Lord": yet this very life of the faithful, when set in contrast to the life of glory, is termed darkness, according to 2 Pet. 1:19: "You have the firm prophetic word, whereunto you do well to attend, as to a light that shineth in a dark place." So the angel's knowledge by which he knows things in their own nature, is day in comparison with ignorance or error; yet it is dark in comparison with the vision of the Word.

Reply Obj. 2: The morning and evening knowledge belong to the day, that is, to the enlightened angels, who are quite apart from the darkness, that is, from the evil spirits. The good angels, while knowing the creature, do not adhere to it, for that would be to turn to darkness and to night; but they refer this back to the praise of God, in Whom, as in their principle, they know all things. Consequently after "evening" there is no night, but "morning"; so that morning is the end of the preceding day, and the beginning of the following, in so far as the angels refer to God's praise their knowledge of the preceding work. Noonday is comprised under the name of day, as the middle between the two extremes. Or else the noon can be referred to their knowledge of God Himself, Who has neither beginning nor end.

Reply Obj. 3: The angels themselves are also creatures. Accordingly the existence of things in the angelic knowledge is comprised under evening knowledge, as also the existence of things in their own nature. _______________________

SEVENTH ARTICLE [I, Q. 58, Art. 7]

Whether the Morning and Evening Knowledge Are One?

Objection 1: It would seem that the morning and the evening knowledge are one. For it is said (Gen. 1:5): "There was evening and morning, one day." But by the expression "day" the knowledge of the angels is to be understood, as Augustine says (Gen. ad lit. iv, 23). Therefore the morning and evening knowledge of the angels are one and the same.

Obj. 2: Further, it is impossible for one faculty to have two operations at the same time. But the angels are always using their morning knowledge; because they are always beholding God and things in God, according to Matt. 18:10. Therefore, if the evening knowledge were different from the morning, the angel could never exercise his evening knowledge.

Obj. 3: Further, the Apostle says (1 Cor. 13:10): "When that which is perfect is come, then that which is in part shall be done away." But, if the evening knowledge be different from the morning, it is compared to it as the less perfect to the perfect. Therefore the evening knowledge cannot exist together with the morning knowledge.

On the contrary, Augustine says (Gen. ad lit. iv, 24): "There is a vast difference between knowing anything as it is in the Word of God, and as it is in its own nature; so that the former belongs to the day, and the latter to the evening."

I answer that, As was observed (A. 6), the evening knowledge is that by which the angels know things in their proper nature. This cannot be understood as if they drew their knowledge from the proper nature of things, so that the preposition "in" denotes the form of a principle; because, as has been already stated (Q. 55, A. 2), the angels do not draw their knowledge from things. It follows, then, that when we say "in their proper nature" we refer to the aspect of the thing known in so far as it is an object of knowledge; that is to say, that the evening knowledge is in the angels in so far as they know the being of things which those things have in their own nature.

Now they know this through a twofold medium, namely, by innate ideas, or by the forms of things existing in the Word. For by beholding the Word, they know not merely the being of things as existing in the Word, but the being as possessed by the things themselves; as God by contemplating Himself sees that being which things have in their own nature. It, therefore, it be called evening knowledge, in so far as when the angels behold the Word, they know the being which things have in their proper nature, then the morning and the evening knowledge are essentially one and the same, and only differ as to the things known. If it be called evening knowledge, in so far as through innate ideas they know the being which things have in their own natures, then the morning and the evening knowledge differ. Thus Augustine seems to understand it when he assigns one as inferior to the other.

Reply Obj. 1: The six days, as Augustine understands them, are taken as the six classes of things known by the angels; so that the day's unit is taken according to the unit of the thing understood; which, nevertheless, can be apprehended by various ways of knowing it.

Reply Obj. 2: There can be two operations of the same faculty at the one time, one of which is referred to the other; as is evident when the will at the same time wills the end and the means to the end; and the intellect at the same instant perceives principles and conclusions through those principles, when it has already acquired knowledge. As Augustine says (Gen. ad lit. iv, 24), the evening knowledge is referred to the morning knowledge in the angels; hence there is nothing to hinder both from being at the same time in the angels.

Reply Obj. 3: On the coming of what is perfect, the opposite imperfect is done away: just as faith, which is of the things that are not seen, is made void when vision succeeds. But the imperfection of the evening knowledge is not opposed to the perfection of the morning knowledge. For that a thing be known in itself, is not opposite to its being known in its cause. Nor, again, is there any inconsistency in knowing a thing through two mediums, one of which is more perfect and the other less perfect; just as we can have a demonstrative and a probable medium for reaching the same conclusion. In like manner a thing can be known by the angel through the uncreated Word, and through an innate idea. _______________________

QUESTION 59

THE WILL OF THE ANGELS (FOUR ARTICLES)

In the next place we must treat of things concerning the will of the angels. In the first place we shall treat of the will itself; secondly, of its movement, which is love. Under the first heading there are four points of inquiry:

(1) Whether there is will in the angels?

(2) Whether the will of the angel is his nature, or his intellect?

(3) Is there free-will in the angels?

(4) Is there an irascible and a concupiscible appetite in them? _______________________

FIRST ARTICLE [I, Q. 59, Art. 1]

Whether There Is Will in the Angels?

Objection 1: It would seem that there is no will in the angels. For as the Philosopher says (De Anima iii, text. 42), "The will is in the reason." But there is no reason in the angels, but something higher than reason. Therefore there is no will in the angels, but something higher than the will.

Obj. 2: Further, the will is comprised under the appetite, as is evident from the Philosopher (De Anima iii, text. 42). But the appetite argues something imperfect; because it is a desire of something not as yet possessed. Therefore, since there is no imperfection in the angels, especially in the blessed ones, it seems that there is no will in them.

Obj. 3: Further, the Philosopher says (De Anima ii, text. 54) that the will is a mover which is moved; for it is moved by the appetible object understood. Now the angels are immovable, since they are incorporeal. Therefore there is no will in the angels.

On the contrary, Augustine says (De Trin. x, 11,12) that the image of the Trinity is found in the soul according to memory, understanding, and will. But God's image is found not only in the soul of man, but also in the angelic mind, since it also is capable of knowing God. Therefore there is will in the angels.

I answer that, We must necessarily place a will in the angels. In evidence thereof, it must be borne in mind that, since all things flow from the Divine will, all things in their own way are inclined by appetite towards good, but in different ways. Some are inclined to good by their natural inclination, without knowledge, as plants and inanimate bodies. Such inclination towards good is called "a natural appetite." Others, again, are inclined towards good, but with some knowledge; not that they know the aspect of goodness, but that they apprehend some particular good; as in the sense, which knows the sweet, the white, and so on. The inclination which follows this apprehension is called "a sensitive appetite." Other things, again, have an inclination towards good, but with a knowledge whereby they perceive the aspect of goodness; this belongs to the intellect. This is most perfectly inclined towards what is good; not, indeed, as if it were merely guided by another towards some particular good only, like things devoid of knowledge, nor towards some particular good only, as things which have only sensitive knowledge, but as inclined towards good in general. Such inclination is termed "will." Accordingly, since the angels by their intellect know the universal aspect of goodness, it is manifest that there is a will in them.

Reply Obj. 1: Reason surpasses sense in a different way from that in which intellect surpasses reason. Reason surpasses sense according to the diversity of the objects known; for sense judges of particular objects, while reason judges of universals. Therefore there must be one appetite tending towards good in the abstract, which appetite belongs to reason; and another with a tendency towards particular good, which appetite belongs to sense. But intellect and reason differ as to their manner of knowing; because the intellect knows by simple intuition, while reason knows by a process of discursion from one thing to another. Nevertheless by such discursion reason comes to know what intellect learns without it, namely, the universal. Consequently the object presented to the appetitive faculty on the part of reason and on the part of intellect is the same. Therefore in the angels, who are purely intellectual, there is no appetite higher than the will.

Reply Obj. 2: Although the name of the appetitive part is derived from seeking things not yet possessed, yet the appetitive part reaches out not to these things only, but also to many other things; thus the name of a stone [lapis] is derived from injuring the foot [laesione pedis], though not this alone belongs to a stone. In the same way the irascible faculty is so denominated from anger [ira]; though at the same time there are several other passions in it, as hope, daring, and the rest.

Reply Obj. 3: The will is called a mover which is moved, according as to will and to understand are termed movements of a kind; and there is nothing to prevent movement of this kind from existing in the angels, since such movement is the act of a perfect agent, as stated in De Anima iii, text. 28. _______________________

SECOND ARTICLE [I, Q. 59, Art. 2]

Whether in the Angels the Will Differs from the Intellect?

Objection 1: It would seem that in the angel the will does not differ from the intellect and from the nature. For an angel is more simple than a natural body. But a natural body is inclined through its form towards its end, which is its good. Therefore much more so is the angel. Now the angel's form is either the nature in which he subsists, or else it is some species within his intellect. Therefore the angel inclines towards the good through his own nature, or through an intelligible species. But such inclination towards the good belongs to the will. Therefore the will of the angel does not differ from his nature or his intellect.

Obj. 2: Further, the object of the intellect is the true, while the object of the will is the good. Now the good and the true differ, not really but only logically [*Cf. Q. 16, A. 4]. Therefore will and intellect are not really different.

Obj. 3: Further, the distinction of common and proper does not differentiate the faculties; for the same power of sight perceives color and whiteness. But the good and the true seem to be mutually related as common to particular; for the true is a particular good, to wit, of the intellect. Therefore the will, whose object is the good, does not differ from the intellect, whose object is the true.

On the contrary, The will in the angels regards good things only, while their intellect regards both good and bad things, for they know both. Therefore the will of the angels is distinct from their intellect.

I answer that, In the angels the will is a special faculty or power, which is neither their nature nor their intellect. That it is not their nature is manifest from this, that the nature or essence of a thing is completely comprised within it: whatever, then, extends to anything beyond it, is not its essence. Hence we see in natural bodies that the inclination to being does not come from anything superadded to the essence, but from the matter which desires being before possessing it, and from the form which keeps it in such being when once it exists. But the inclination towards something extrinsic comes from something superadded to the essence; as tendency to a place comes from gravity or lightness, while the inclination to make something like itself comes from the active qualities.

Now the will has a natural tendency towards good. Consequently there alone are essence and will identified where all good is contained within the essence of him who wills; that is to say, in God, Who wills nothing beyond Himself except on account of His goodness. This cannot be said of any creature, because infinite goodness is quite foreign to the nature of any created thing. Accordingly, neither the will of the angel, nor that of any creature, can be the same thing as its essence.

In like manner neither can the will be the same thing as the intellect of angel or man. Because knowledge comes about in so far as the object known is within the knower; consequently the intellect extends itself to what is outside it, according as what, in its essence, is outside it is disposed to be somehow within it. On the other hand, the will goes out to what is beyond it, according as by a kind of inclination it tends, in a manner, to what is outside it. Now it belongs to one faculty to have within itself something which is outside it, and to another faculty to tend to what is outside it. Consequently intellect and will must necessarily be different powers in every creature. It is not so with God, for He has within Himself universal being, and the universal good. Therefore both intellect and will are His nature.

Reply Obj. 1: A natural body is moved to its own being by its substantial form: while it is inclined to something outside by something additional, as has been said.

Reply Obj. 2: Faculties are not differentiated by any material difference of their objects, but according to their formal distinction, which is taken from the nature of the object as such. Consequently the diversity derived from the notion of good and true suffices for the difference of intellect from will.

Reply Obj. 3: Because the good and the true are really convertible, it follows that the good is apprehended by the intellect as something true; while the true is desired by the will as something good. Nevertheless, the diversity of their aspects is sufficient for diversifying the faculties, as was said above (ad 2). _______________________

THIRD ARTICLE [I, Q. 59, Art. 3]

Whether There Is Free-Will in the Angels?

Objection 1: It would seem that there is no free-will in the angels. For the act of free-will is to choose. But there can be no choice with the angels, because choice is "the desire of something after taking counsel," while counsel is "a kind of inquiry," as stated in Ethic. iii, 3. But the angels' knowledge is not the result of inquiring, for this belongs to the discursiveness of reason. Therefore it appears that there is no free-will in the angels.

Obj. 2: Further, free-will implies indifference to alternatives. But in the angels on the part of their intellect there is no such indifference; because, as was observed already (Q. 58, A. 5), their intellect is not deceived as to things which are naturally intelligible to them. Therefore neither on the part of their appetitive faculty can there be free-will.

Obj. 3: Further, the natural endowments of the angels belong to them according to degrees of more or less; because in the higher angels the intellectual nature is more perfect than in the lower. But the free-will does not admit of degrees. Therefore there is no free-will in them.

On the contrary, Free-will is part of man's dignity. But the angels' dignity surpasses that of men. Therefore, since free-will is in men, with much more reason is it in the angels.

I answer that, Some things there are which act, not from any previous judgment, but, as it were, moved and made to act by others; just as the arrow is directed to the target by the archer. Others act from some kind of judgment; but not from free-will, such as irrational animals; for the sheep flies from the wolf by a kind of judgment whereby it esteems it to be hurtful to itself: such a judgment is not a free one, but implanted by nature. Only an agent endowed with an intellect can act with a judgment which is free, in so far as it apprehends the common note of goodness; from which it can judge this or the other thing to be good. Consequently, wherever there is intellect, there is free-will. It is therefore manifest that just as there is intellect, so is there free-will in the angels, and in a higher degree of perfection than in man.

Reply Obj. 1: The Philosopher is speaking of choice, as it is in man. As a man's estimate in speculative matters differs from an angel's in this, that the one needs not to inquire, while the other does so need; so is it in practical matters. Hence there is choice in the angels, yet not with the inquisitive deliberation of counsel, but by the sudden acceptance of truth.

Reply Obj. 2: As was observed already (A. 2), knowledge is effected by the presence of the known within the knower. Now it is a mark of imperfection in anything not to have within it what it should naturally have. Consequently an angel would not be perfect in his nature, if his intellect were not determined to every truth which he can know naturally. But the act of the appetitive faculty comes of this, that the affection is directed to something outside. Yet the perfection of a thing does not come from everything to which it is inclined, but only from something which is higher than it. Therefore it does not argue imperfection in an angel if his will be not determined with regard to things beneath him; but it would argue imperfection in him, were he to be indeterminate to what is above him.

Reply Obj. 3: Free-will exists in a nobler manner in the higher angels than it does in the lower, as also does the judgment of the intellect. Yet it is true that liberty, in so far as the removal of compulsion is considered, is not susceptible of greater and less degree; because privations and negations are not lessened nor increased directly of themselves; but only by their cause, or through the addition of some qualification. _______________________

FOURTH ARTICLE [I, Q. 59, Art. 4]

Whether There Is an Irascible and a Concupiscible Appetite in the Angels?

Objection 1: It would seem that there is an irascible and a concupiscible appetite in the angels. For Dionysius says (Div. Nom. iv) that in the demons there is "unreasonable fury and wild concupiscence." But demons are of the same nature as angels; for sin has not altered their nature. Therefore there is an irascible and a concupiscible appetite in the angels.

Obj. 2: Further, love and joy are in the concupiscible; while anger, hope, and fear are in the irascible appetite. But in the Sacred Scriptures these things are attributed both to the good and to the wicked angels. Therefore there is an irascible and a concupiscible appetite in the angels.

Obj. 3: Further, some virtues are said to reside in the irascible appetite and some in the concupiscible: thus charity and temperance appear to be in the concupiscible, while hope and fortitude are in the irascible. But these virtues are in the angels. Therefore there is both a concupiscible and an irascible appetite in the angels.

On the contrary, The Philosopher says (De Anima iii, text. 42) that the irascible and concupiscible are in the sensitive part, which does not exist in angels. Consequently there is no irascible or concupiscible appetite in the angels.

I answer that, The intellective appetite is not divided into irascible and concupiscible; only the sensitive appetite is so divided. The reason of this is because, since the faculties are distinguished from one another not according to the material but only by the formal distinction of objects, if to any faculty there respond an object according to some common idea, there will be no distinction of faculties according to the diversity of the particular things contained under that common idea. Just as if the proper object of the power of sight be color as such, then there are not several powers of sight distinguished according to the difference of black and white: whereas if the proper object of any faculty were white, as white, then the faculty of seeing white would be distinguished from the faculty of seeing black.

Now it is quite evident from what has been said (A. 1; Q. 16, A. 1), that the object of the intellective appetite, otherwise known as the will, is good according to the common aspect of goodness; nor can there be any appetite except of what is good. Hence, in the intellective part, the appetite is not divided according to the distinction of some particular good things, as the sensitive appetite is divided, which does not crave for what is good according to its common aspect, but for some particular good object. Accordingly, since there exists in the angels only an intellective appetite, their appetite is not distinguished into irascible and concupiscible, but remains undivided; and it is called the will.

Reply Obj. 1: Fury and concupiscence are metaphorically said to be in the demons, as anger is sometimes attributed to God;—on account of the resemblance in the effect.

Reply Obj. 2: Love and joy, in so far as they are passions, are in the concupiscible appetite, but in so far as they express a simple act of the will, they are in the intellective part: in this sense to love is to wish well to anyone; and to be glad is for the will to repose in some good possessed. Universally speaking, none of these things is said of the angels, as by way of passions; as Augustine says (De Civ. Dei ix).

Reply Obj. 3: Charity, as a virtue, is not in the concupiscible appetite, but in the will; because the object of the concupiscible appetite is the good as delectable to the senses. But the Divine goodness, which is the object of charity, is not of any such kind. For the same reason it must be said that hope does not exist in the irascible appetite; because the object of the irascible appetite is something arduous belonging to the sensible order, which the virtue of hope does not regard; since the object of hope is arduous and divine. Temperance, however, considered as a human virtue, deals with the desires of sensible pleasures, which belong to the concupiscible faculty. Similarly, fortitude regulates daring and fear, which reside in the irascible part. Consequently temperance, in so far as it is a human virtue, resides in the concupiscible part, and fortitude in the irascible. But they do not exist in the angels in this manner. For in them there are no passions of concupiscence, nor of fear and daring, to be regulated by temperance and fortitude. But temperance is predicated of them according as in moderation they display their will in conformity with the Divine will. Fortitude is likewise attributed to them, in so far as they firmly carry out the Divine will. All of this is done by their will, and not by the irascible or concupiscible appetite. _______________________

QUESTION 60

OF THE LOVE OR DILECTION OF THE ANGELS (In Five Articles)

The next subject for our consideration is that act of the will which is love or dilection; because every act of the appetitive faculty comes of love.

Under this heading there are five points of inquiry:

(1) Whether there is natural love in the angels?

(2) Whether there is in them love of choice?

(3) Whether the angel loves himself with natural love or with love of choice?

(4) Whether one angel loves another with natural love as he loves himself?

(5) Whether the angel loves God more than self with natural love? _______________________

FIRST ARTICLE [I, Q. 60, Art. 1]

Whether There Is Natural Love or Dilection in an Angel?

Objection 1: It would seem that there is no natural love or dilection in the angels. For, natural love is contradistinguished from intellectual love, as stated by Dionysius (Div. Nom. iv). But an angel's love is intellectual. Therefore it is not natural.

Obj. 2: Further, those who love with natural love are more acted upon than active in themselves; for nothing has control over its own nature. Now the angels are not acted upon, but act of themselves; because they possess free-will, as was shown above (Q. 59, A. 3). Consequently there is no natural love in them.

Obj. 3: Further, every love is either ordinate or inordinate. Now ordinate love belongs to charity; while inordinate love belongs to wickedness. But neither of these belongs to nature; because charity is above nature, while wickedness is against nature. Therefore there is no natural love in the angels.

On the contrary, Love results from knowledge; for, nothing is loved except it be first known, as Augustine says (De Trin. x, 1,2). But there is natural knowledge in the angels. Therefore there is also natural love.

I answer that, We must necessarily place natural love in the angels. In evidence of this we must bear in mind that what comes first is always sustained in what comes after it. Now nature comes before intellect, because the nature of every subject is its essence. Consequently whatever belongs to nature must be preserved likewise in such subjects as have intellect. But it is common to every nature to have some inclination; and this is its natural appetite or love. This inclination is found to exist differently in different natures; but in each according to its mode. Consequently, in the intellectual nature there is to be found a natural inclination coming from the will; in the sensitive nature, according to the sensitive appetite; but in a nature devoid of knowledge, only according to the tendency of the nature to something. Therefore, since an angel is an intellectual nature, there must be a natural love in his will.

Reply Obj. 1: Intellectual love is contradistinguished from that natural love, which is merely natural, in so far as it belongs to a nature which has not likewise the perfection of either sense or intellect.

Reply Obj. 2: All things in the world are moved to act by something else except the First Agent, Who acts in such a manner that He is in no way moved to act by another; and in Whom nature and will are the same. So there is nothing unfitting in an angel being moved to act in so far as such natural inclination is implanted in him by the Author of his nature. Yet he is not so moved to act that he does not act himself, because he has free-will.

Reply Obj. 3: As natural knowledge is always true, so is natural love well regulated; because natural love is nothing else than the inclination implanted in nature by its Author. To say that a natural inclination is not well regulated, is to derogate from the Author of nature. Yet the rectitude of natural love is different from the rectitude of charity and virtue: because the one rectitude perfects the other; even so the truth of natural knowledge is of one kind, and the truth of infused or acquired knowledge is of another. _______________________
