Question: 111 THE ACTION OF THE ANGELS ON MAN (FOUR ARTICLES)

   We now consider the action of the angels on man, and inquire: (1) How far they can change them by their own natural power; (2) How they are sent by God to the ministry of men; (3) How they guard and protect men.

   Under the first head there are four points of inquiry:

    (1) Whether an angel can enlighten the human intellect?

    (2) Whether he can change man's will?

    (3) Whether he can change man's imagination?

    (4) Whether he can change man's senses?

Article: 1 

Whether an angel can enlighten man?

  Objection 1: It would seem that an angel cannot enlighten man. For man is enlightened by faith; hence Dionysius (Eccl. Hier. iii) attributes enlightenment to baptism, as "the sacrament of faith." But faith is immediately from God, according to Eph. 2:8: "By grace you are saved through faith, and that not of yourselves, for it is the gift of God." Therefore man is not enlightened by an angel; but immediately by God.

  Objection 2: Further, on the words, "God hath manifested it to them" (Rm. 1:19), the gloss observes that "not only natural reason availed for the manifestation of Divine truths to men, but God also revealed them by His work," that is, by His creature. But both are immediately from God---that is, natural reason and the creature. Therefore God enlightens man immediately.

  Objection 3: Further, whoever is enlightened is conscious of being enlightened. But man is not conscious of being enlightened by angels. Therefore he is not enlightened by them.

  On the contrary, Dionysius says (Coel. Hier. iv) that the revelation of Divine things reaches men through the ministry of the angels. But such revelation is an enlightenment as we have stated (Question [106], Article [1]; Question [107], Article [2]). Therefore men are enlightened by the angels.

  I answer that, Since the order of Divine Providence disposes that lower things be subject to the actions of higher, as explained above (Question [109], Article [2]); as the inferior angels are enlightened by the superior, so men, who are inferior to the angels, are enlightened by them.

   The modes of each of these kinds of enlightenment are in one way alike and in another way unlike. For, as was shown above (Question [106], Article [1]), the enlightenment which consists in making known Divine truth has two functions; namely, according as the inferior intellect is strengthened by the action of the superior intellect, and according as the intelligible species which are in the superior intellect are proposed to the inferior so as to be grasped thereby. This takes place in the angels when the superior angel divides his universal concept of the truth according to the capacity of the inferior angel, as explained above (Question [106], Article [1]).

   The human intellect, however, cannot grasp the universal truth itself unveiled; because its nature requires it to understand by turning to the phantasms, as above explained (Question [84], Article [7]). So the angels propose the intelligible truth to men under the similitudes of sensible things, according to what Dionysius says (Coel. Hier. i), that, "It is impossible for the divine ray to shine on us, otherwise than shrouded by the variety of the sacred veils." On the other hand, the human intellect as the inferior, is strengthened by the action of the angelic intellect. And in these two ways man is enlightened by an angel.

  Reply to Objection 1: Two dispositions concur in the virtue of faith; first, the habit of the intellect whereby it is disposed to obey the will tending to Divine truth. For the intellect assents to the truth of faith, not as convinced by the reason, but as commanded by the will; hence Augustine says, "No one believes except willingly." In this respect faith comes from God alone. Secondly, faith requires that what is to be believed be proposed to the believer; which is accomplished by man, according to Rm. 10:17, "Faith cometh by hearing"; principally, however, by the angels, by whom Divine things are revealed to men. Hence the angels have some part in the enlightenment of faith. Moreover, men are enlightened by the angels not only concerning what is to be believed; but also as regards what is to be done.

  Reply to Objection 2: Natural reason, which is immediately from God, can be strengthened by an angel, as we have said above. Again, the more the human intellect is strengthened, so much higher an intelligible truth can be elicited from the species derived from creatures. Thus man is assisted by an angel so that he may obtain from creatures a more perfect knowledge of God.

  Reply to Objection 3: Intellectual operation and enlightenment can be understood in two ways. First, on the part of the object understood; thus whoever understands or is enlightened, knows that he understands or is enlightened, because he knows that the object is made known to him. Secondly, on the part of the principle; and thus it does not follow that whoever understands a truth, knows what the intellect is, which is the principle of the intellectual operation. In like manner not everyone who is enlightened by an angel, knows that he is enlightened by him.

Whether the angels can change the will of man?

  Objection 1: It would seem that the angels can change the will of man. For, upon the text, "Who maketh His angels spirits and His ministers a flame of fire" (Heb. 1:7), the gloss notes that "they are fire, as being spiritually fervent, and as burning away our vices." This could not be, however, unless they changed the will. Therefore the angels can change the will.

  Objection 2: Further, Bede says (Super Matth. xv, 11), that, "the devil does not send wicked thoughts, but kindles them." Damascene, however, says that he also sends them; for he remarks that "every malicious act and unclean passion is contrived by the demons and put into men" (De Fide Orth. ii, 4); in like manner also the good angels introduce and kindle good thoughts. But this could only be if they changed the will. Therefore the will is changed by them.

  Objection 3: Further, the angel, as above explained, enlightens the human intellect by means of the phantasms. But as the imagination which serves the intellect can be changed by an angel, so can the sensitive appetite which serves the will, because it also is a faculty using a corporeal organ. Therefore as the angel enlightens the mind, so can he change the will.

  On the contrary, To change the will belongs to God alone, according to Prov. 21:1: "The heart of the king is in the hand of the Lord, whithersoever He will He shall turn it."

  I answer that, The will can be changed in two ways. First, from within; in which way, since the movement of the will is nothing but the inclination of the will to the thing willed, God alone can thus change the will, because He gives the power of such an inclination to the intellectual nature. For as the natural inclination is from God alone Who gives the nature, so the inclination of the will is from God alone, Who causes the will.

   Secondly, the will is moved from without. As regards an angel, this can be only in one way---by the good apprehended by the intellect. Hence in as far as anyone may be the cause why anything be apprehended as an appetible good, so far does he move the will. In this way also God alone can move the will efficaciously; but an angel and man move the will by way of persuasion, as above explained (Question [106], Article [2]).

   In addition to this mode the human will can be moved from without in another way; namely, by the passion residing in the sensitive appetite: thus by concupiscence or anger the will is inclined to will something. In this manner the angels, as being able to rouse these passions, can move the will, not however by necessity, for the will ever remains free to consent to, or to resist, the passion.

  Reply to Objection 1: Those who act as God's ministers, either men or angels, are said to burn away vices, and to incite to virtue by way of persuasion.

  Reply to Objection 2: The demon cannot put thoughts in our minds by causing them from within, since the act of the cogitative faculty is subject to the will; nevertheless the devil is called the kindler of thoughts, inasmuch as he incites to thought, by the desire of the things thought of, by way of persuasion, or by rousing the passions. Damascene calls this kindling "a putting in" because such a work is accomplished within. But good thoughts are attributed to a higher principle, namely, God, though they may be procured by the ministry of the angels.

  Reply to Objection 3: The human intellect in its present state can understand only by turning to the phantasms; but the human will can will something following the judgment of reason rather than the passion of the sensitive appetite. Hence the comparison does not hold.
 
Article: 3  

Whether an angel can change man's imagination?

  Objection 1: It would seem that an angel cannot change man's imagination. For the phantasy, as is said De Anima iii, is "a motion caused by the sense in act." But if this motion were caused by an angel, it would not be caused by the sense in act. Therefore it is contrary to the nature of the phantasy, which is the act of the imaginative faculty, to be changed by an angel.

  Objection 2: Further, since the forms in the imagination are spiritual, they are nobler than the forms existing in sensible matter. But an angel cannot impress forms upon sensible matter (Question [110], Article [2]). Therefore he cannot impress forms on the imagination, and so he cannot change it.

  Objection 3: Further, Augustine says (Gen. ad lit. xii, 12): "One spirit by intermingling with another can communicate his knowledge to the other spirit by these images, so that the latter either understands it himself, or accepts it as understood by the other." But it does not seem that an angel can be mingled with the human imagination, nor that the imagination can receive the knowledge of an angel. Therefore it seems that an angel cannot change the imagination.

  Objection 4: Further, in the imaginative vision man cleaves to the similitudes of the things as to the things themselves. But in this there is deception. So as a good angel cannot be the cause of deception, it seems that he cannot cause the imaginative vision, by changing the imagination.

  On the contrary, Those things which are seen in dreams are seen by imaginative vision. But the angels reveal things in dreams, as appears from Mt. 1:20;[2]:13,[19] in regard to the angel who appeared to Joseph in dreams. Therefore an angel can move the imagination.

  I answer that, Both a good and a bad angel by their own natural power can move the human imagination. This may be explained as follows. For it was said above (Question [110], Article [3]), that corporeal nature obeys the angel as regards local movement, so that whatever can be caused by the local movement of bodies is subject to the natural power of the angels. Now it is manifest that imaginative apparitions are sometimes caused in us by the local movement of animal spirits and humors. Hence Aristotle says (De Somn. et Vigil.) [*De Insomniis iii.], when assigning the cause of visions in dreams, that "when an animal sleeps, the blood descends in abundance to the sensitive principle, and movements descend with it," that is, the impressions left from the movements are preserved in the animal spirits, "and move the sensitive principle"; so that a certain appearance ensues, as if the sensitive principle were being then changed by the external objects themselves. Indeed, the commotion of the spirits and humors may be so great that such appearances may even occur to those who are awake, as is seen in mad people, and the like. So, as this happens by a natural disturbance of the humors, and sometimes also by the will of man who voluntarily imagines what he previously experienced, so also the same may be done by the power of a good or a bad angel, sometimes with alienation from the bodily senses, sometimes without such alienation.

  Reply to Objection 1: The first principle of the imagination is from the sense in act. For we cannot imagine what we have never perceived by the senses, either wholly or partly; as a man born blind cannot imagine color. Sometimes, however, the imagination is informed in such a way that the act of the imaginative movement arises from the impressions preserved within.

  Reply to Objection 2: An angel changes the imagination, not indeed by the impression of an imaginative form in no way previously received from the senses (for he cannot make a man born blind imagine color), but by local movement of the spirits and humors, as above explained.

  Reply to Objection 3: The commingling of the angelic spirit with the human imagination is not a mingling of essences, but by reason of an effect which he produces in the imagination in the way above stated; so that he shows man what he [the angel] knows, but not in the way he knows.

  Reply to Objection 4: An angel causing an imaginative vision, sometimes enlightens the intellect at the same time, so that it knows what these images signify; and then there is not deception. But sometimes by the angelic operation the similitudes of things only appear in the imagination; but neither then is deception caused by the angel, but by the defect in the intellect to whom such things appear. Thus neither was Christ a cause of deception when He spoke many things to the people in parables, which He did not explain to them.

Article: 4 

Whether an angel can change the human senses?

  Objection 1: It seems that an angel cannot change the human senses. For the sensitive operation is a vital operation. But such an operation does not come from an extrinsic principle. Therefore the sensitive operation cannot be caused by an angel.

  Objection 2: Further, the sensitive operation is nobler than the nutritive. But the angel cannot change the nutritive power, nor other natural forms. Therefore neither can he change the sensitive power.

  Objection 3: Further, the senses are naturally moved by the sensible objects. But an angel cannot change the order of nature (Question [110], Article [4]). Therefore an angel cannot change the senses; but these are changed always by the sensible object.

  On the contrary, The angels who overturned Sodom, "struck the people of Sodom with blindness or {aorasia}, so that they could not find the door" (Gn. 19:11). [*It is worth noting that these are the only two passages in the Greek version where the word {aorasia} appears. It expresses, in fact, the effect produced on the people of Sodom---namely, dazzling (French version, "eblouissement"), which the Latin "caecitas" (blindness) does not necessarily imply.] The same is recorded of the Syrians whom Eliseus led into Samaria (4 Kgs. 6:18).

  I answer that, The senses may be changed in a twofold manner; from without, as when affected by the sensible object: and from within, for we see that the senses are changed when the spirits and humors are disturbed; as for example, a sick man's tongue, charged with choleric humor, tastes everything as bitter, and the like with the other senses. Now an angel, by his natural power, can work a change in the senses both ways. For an angel can offer the senses a sensible object from without, formed by nature or by the angel himself, as when he assumes a body, as we have said above (Question [51], Article [2]). Likewise he can move the spirits and humors from within, as above remarked, whereby the senses are changed in various ways.

  Reply to Objection 1: The principle of the sensitive operation cannot be without the interior principle which is the sensitive power; but this interior principle can be moved in many ways by the exterior principle, as above explained.

  Reply to Objection 2: By the interior movement of the spirits and humors an angel can do something towards changing the act of the nutritive power, and also of the appetitive and sensitive power, and of any other power using a corporeal organ.

  Reply to Objection 3: An angel can do nothing outside the entire order of creatures; but he can outside some particular order of nature, since he is not subject to that order; thus in some special way an angel can work a change in the senses outside the common mode of nature.

Question: 112  THE MISSION OF THE ANGELS (FOUR ARTICLES)

   We next consider the mission of the angels. Under this head arise four points of inquiry:

    (1) Whether any angels are sent on works of ministry?

    (2) Whether all are sent?

    (3) Whether those who are sent, assist?

    (4) From what orders they are sent.
 
Article: 1 

Whether the angels are sent on works of ministry?

  Objection 1: It would seem that the angels are not sent on works of ministry. For every mission is to some determinate place. But intellectual actions do not determine a place, for intellect abstracts from the "here" and "now." Since therefore the angelic actions are intellectual, it appears that the angels are not sent to perform their own actions.

  Objection 2: Further, the empyrean heaven is the place that beseems the angelic dignity. Therefore if they are sent to us in ministry, it seems that something of their dignity would be lost; which is unseemly.

  Objection 3: Further, external occupation hinders the contemplation of wisdom; hence it is said: "He that is less in action, shall receive wisdom" (Ecclus. 38:25). So if some angels are sent on external ministrations, they would seemingly be hindered from contemplation. But the whole of their beatitude consists in the contemplation of God. So if they were sent, their beatitude would be lessened; which is unfitting.

  Objection 4: Further, to minister is the part of an inferior; hence it is written (Lk. 22:27): "Which is the greater, he that sitteth at table, or he that serveth? is not he that sitteth at table?" But the angels are naturally greater than we are. Therefore they are not sent to administer to us.

  On the contrary, It is written (Ex. 23:20): "Behold I will send My angels who shall go before thee."

  I answer that, From what has been said above (Question [108], Article [6]), it may be shown that some angels are sent in ministry by God. For, as we have already stated (Question [43], Article [1]), in treating of the mission of the Divine Persons, he is said to be sent who in any way proceeds from another so as to begin to be where he was not, or to be in another way, where he already was. Thus the Son, or the Holy Ghost is said to be sent as proceeding from the Father by origin; and begins to be in a new way, by grace or by the nature assumed, where He was before by the presence of His Godhead; for it belongs to God to be present everywhere, because, since He is the universal agent, His power reaches to all being, and hence He exists in all things (Question [8], Article [1]). An angel's power, however, as a particular agent, does not reach to the whole universe, but reaches to one thing in such a way as not to reach another; and so he is "here" in such a manner as not to be "there." But it is clear from what was above stated (Question [110], Article [1]), that the corporeal creature is governed by the angels. Hence, whenever an angel has to perform any work concerning a corporeal creature, the angel applies himself anew to that body by his power; and in that way begins to be there afresh. Now all this takes place by Divine command. Hence it follows that an angel is sent by God.

   Yet the action performed by the angel who is sent, proceeds from God as from its first principle, at Whose nod and by Whose authority the angels work; and is reduced to God as to its last end. Now this is what is meant by a minister: for a minister is an intelligent instrument; while an instrument is moved by another, and its action is ordered to another. Hence angels' actions are called 'ministries'; and for this reason they are said to be sent in ministry.

  Reply to Objection 1: An operation can be intellectual in two ways. In one way, as dwelling in the intellect itself, as contemplation; such an operation does not demand to occupy a place; indeed, as Augustine says (De Trin. iv, 20): "Even we ourselves as mentally tasting something eternal, are not in this world." In another sense an action is said to be intellectual because it is regulated and commanded by some intellect; in that sense the intellectual operations evidently have sometimes a determinate place.

  Reply to Objection 2: The empyrean heaven belongs to the angelic dignity by way of congruity; forasmuch as it is congruous that the higher body should be attributed to that nature which occupies a rank above bodies. Yet an angel does not derive his dignity from the empyrean heaven; so when he is not actually in the empyrean heaven, nothing of his dignity is lost, as neither does a king lessen his dignity when not actually sitting on his regal throne, which suits his dignity.

  Reply to Objection 3: In ourselves the purity of contemplation is obscured by exterior occupation; because we give ourselves to action through the sensitive faculties, the action of which when intense impedes the action of the intellectual powers. An angel, on the contrary, regulates his exterior actions by intellectual operation alone. Hence it follows that his external occupations in no respect impede his contemplation; because given two actions, one of which is the rule and the reason of the other, one does not hinder but helps the other. Wherefore Gregory says (Moral. ii) that "the angels do not go abroad in such a manner as to lose the delights of inward contemplation."

  Reply to Objection 4: In their external actions the angels chiefly minister to God, and secondarily to us; not because we are superior to them, absolutely speaking, but because, since every man or angel by cleaving to God is made one spirit with God, he is thereby superior to every creature. Hence the Apostle says (Phil. 2:3): "Esteeming others better than themselves."

Article: 2  

Whether all the angels are sent in ministry?

  Objection 1: It would seem that all the angels are sent in ministry. For the Apostle says (Heb. 1:14): "All are ministering spirits, sent to minister" [Vulg. 'Are they not all . . . ?'].

  Objection 2: Further, among the orders, the highest is that of the Seraphim, as stated above (Question [108], Article [6]). But a Seraph was sent to purify the lips of the prophet (Is. 6:6,7). Therefore much more are the inferior orders sent.

  Objection 3: Further, the Divine Persons infinitely excel all the angelic orders. But the Divine Persons are sent. Therefore much more are even the highest angels sent.

  Objection 4: Further, if the superior angels are not sent to the external ministries, this can only be because the superior angels execute the Divine ministries by means of the inferior angels. But as all the angels are unequal, as stated above (Question [50], Article [4]), each angel has an angel inferior to himself except the last one. Therefore only the last angel would be sent in ministry; which contradicts the words, "Thousands of thousands ministered to Him" (Dan. 7:10).

  On the contrary, Gregory says (Hom. xxxiv in Evang.), quoting the statement of Dionysius (Coel. Hier. xiii), that "the higher ranks fulfil no exterior service."

  I answer that, As appears from what has been said above (Question [106], Article [3]; Question [110], Article [1]), the order of Divine Providence has so disposed not only among the angels, but also in the whole universe, that inferior things are administered by the superior. But the Divine dispensation, however, this order is sometimes departed from as regards corporeal things, for the sake of a higher order, that is, according as it is suitable for the manifestation of grace. That the man born blind was enlightened, that Lazarus was raised from the dead, was accomplished immediately by God without the action of the heavenly bodies. Moreover both good and bad angels can work some effect in these bodies independently of the heavenly bodies, by the condensation of the clouds to rain, and by producing some such effects. Nor can anyone doubt that God can immediately reveal things to men without the help of the angels, and the superior angels without the inferior. From this standpoint some have said that according to the general law the superior angels are not sent, but only the inferior; yet that sometimes, by Divine dispensation, the superior angels also are sent.

   It may also be said that the Apostle wishes to prove that Christ is greater than the angels who were chosen as the messengers of the law; in order that He might show the excellence of the new over the old law. Hence there is no need to apply this to any other angels besides those who were sent to give the law.

  Reply to Objection 2: According to Dionysius (Coel. Hier. xiii), the angel who was sent to purify the prophet's lips was one of the inferior order; but was called a "Seraph," that is, "kindling " in an equivocal sense, because he came to "kindle" the lips of the prophet. It may also be said that the superior angels communicate their own proper gifts whereby they are denominated, through the ministry of the inferior angels. Thus one of the Seraphim is described as purifying by fire the prophet's lips, not as if he did so immediately, but because an inferior angel did so by his power; as the Pope is said to absolve a man when he gives absolution by means of someone else.

  Reply to Objection 3: The Divine Persons are not sent in ministry, but are said to be sent in an equivocal sense, as appears from what has been said (Question [43], Article [1]).

  Reply to Objection 4: A manifold grade exists in the Divine ministries. Hence there is nothing to prevent angels though unequal from being sent immediately in ministry, in such a manner however that the superior are sent to the higher ministries, and the lower to the inferior ministries.
 
Article: 3 

Whether all the angels who are sent, assist?

  Objection 1: It would seem that the angels who are sent also assist. For Gregory says (Hom. xxxiv in Evang.): "So the angels are sent, and assist; for, though the angelic spirit is limited, yet the supreme Spirit, God, is not limited."

  Objection 2: Further, the angel was sent to administer to Tobias. Yet he said, "I am the angel Raphael, one of the seven who stand before the Lord" (Tob. 12:15). Therefore the angels who are sent, assist.

  Objection 3: Further, every holy angel is nearer to God than Satan is. Yet Satan assisted God, according to Job 1:6: "When the sons of God came to stand before the Lord, Satan also was present among them." Therefore much more do the angels, who are sent to minister, assist.

  Objection 4: Further, if the inferior angels do not assist, the reason is because they receive the Divine enlightenment, not immediately, but through the superior angels. But every angel receives the Divine enlightenment from a superior, except the one who is highest of all. Therefore only the highest angel would assist; which is contrary to the text of Dan. 7:10: "Ten thousand times a hundred thousand stood before Him." Therefore the angels who are sent also assist.

  On the contrary, Gregory says, on Job 25:3: "Is there any numbering of His soldiers?" (Moral. xvii): "Those powers assist, who do not go forth as messengers to men." Therefore those who are sent in ministry do not assist.

  I answer that, The angels are spoken of as "assisting" and "administering," after the likeness of those who attend upon a king; some of whom ever wait upon him, and hear his commands immediately; while others there are to whom the royal commands are conveyed by those who are in attendance---for instance, those who are placed at the head of the administration of various cities; these are said to administer, not to assist.

   We must therefore observe that all the angels gaze upon the Divine Essence immediately; in regard to which all, even those who minister, are said to assist. Hence Gregory says (Moral. ii) that "those who are sent on the external ministry of our salvation can always assist and see the face of the Father." Yet not all the angels can perceive the secrets of the Divine mysteries in the clearness itself of the Divine Essence; but only the superior angels who announce them to the inferior: and in that respect only the superior angels belonging to the highest hierarchy are said to assist, whose special prerogative it is to be enlightened immediately by God.

   From this may be deduced the reply to the first and second objections, which are based on the first mode of assisting.

  Reply to Objection 3: Satan is not described as having assisted, but as present among the assistants; for, as Gregory says (Moral. ii), "though he has lost beatitude, still he has retained a nature like to the angels."

  Reply to Objection 4: All the assistants see some things immediately in the glory of the Divine Essence; and so it may be said that it is the prerogative of the whole of the highest hierarchy to be immediately enlightened by God; while the higher ones among them see more than is seen by the inferior; some of whom enlighten others: as also among those who assist the king, one knows more of the king's secrets than another.

Article: 4 

Whether all the angels of the second hierarchy are sent?

  Objection 1: It would seem that all the angels of the second hierarchy are sent. For all the angels either assist, or minister, according to Dan. 7:10. But the angels of the second hierarchy do not assist; for they are enlightened by the angels of the first hierarchy, as Dionysius says (Coel. Hier. viii). Therefore all the angels of the second hierarchy are sent in ministry.

  Objection 2: Further, Gregory says (Moral. xvii) that "there are more who minister than who assist." This would not be the case if the angels of the second hierarchy were not sent in ministry. Therefore all the angels of the second hierarchy are sent to minister.

  On the contrary, Dionysius says (Coel. Hier. viii) that the "Dominations are above all subjection." But to be sent implies subjection. Therefore the dominations are not sent to minister.

  I answer that, As above stated (Article [1]), to be sent to external ministry properly belongs to an angel according as he acts by Divine command in respect of any corporeal creature; which is part of the execution of the Divine ministry. Now the angelic properties are manifested by their names, as Dionysius says (Coel. Hier. vii); and therefore the angels of those orders are sent to external ministry whose names signify some kind of administration. But the name "dominations" does not signify any such administration, but only disposition and command in administering. On the other hand, the names of the inferior orders imply administration, for the "Angels" and "Archangels" are so called from "announcing"; the "Virtues" and "Powers" are so called in respect of some act; and it is right that the "Prince," according to what Gregory says (Hom. xxxiv in Evang.), "be first among the workers." Hence it belongs to these five orders to be sent to external ministry; not to the four superior orders.

  Reply to Objection 1: The Dominations are reckoned among the ministering angels, not as exercising but as disposing and commanding what is to be done by others; thus an architect does not put his hands to the production of his art, but only disposes and orders what others are to do.

  Reply to Objection 2: A twofold reason may be given in assigning the number of the assisting and ministering angels. For Gregory says that those who minister are more numerous than those who assist; because he takes the words (Dan. 7:10) "thousands of thousands ministered to Him," not in a multiple but in a partitive sense, to mean "thousands out of thousands"; thus the number of those who minister is indefinite, and signifies excess; while the number of assistants is finite as in the words added, "and ten thousand times a hundred thousand assisted Him." This explanation rests on the opinion of the Platonists, who said that the nearer things are to the one first principle, the smaller they are in number; as the nearer a number is to unity, the lesser it is than multitude. This opinion is verified as regards the number of orders, as six administer and three assist.

   Dionysius, however, (Coel. Hier. xiv) declares that the multitude of angels surpasses all the multitude of material things; so that, as the superior bodies exceed the inferior in magnitude to an immeasurable degree, so the superior incorporeal natures surpass all corporeal natures in multitude; because whatever is better is more intended and more multiplied by God. Hence, as the assistants are superior to the ministers there will be more assistants than ministers. In this way, the words "thousands of thousands" are taken by way of multiplication, to signify "a thousand times a thousand." And because ten times a hundred is a thousand, if it were said "ten times a hundred thousand" it would mean that there are as many assistants as ministers: but since it is written "ten thousand times a hundred thousand," we are given to understand that the assistants are much more numerous than the ministers. Nor is this said to signify that this is the precise number of angels, but rather that it is much greater, in that it exceeds all material multitude. This is signified by the multiplication together of all the greatest numbers, namely ten, a hundred, and a thousand, as Dionysius remarks in the same passage.

Question: 113 OF THE GUARDIANSHIP OF THE GOOD ANGELS (EIGHT ARTICLES)

   We next consider the guardianship exercised by the good angels; and their warfare against the bad angels. Under the first head eight points of inquiry arise:

    (1) Whether men are guarded by the angels?

    (2) Whether to each man is assigned a single guardian angel?

    (3) Whether the guardianship belongs only to the lowest order of angels?

    (4) Whether it is fitting for each man to have an angel guardian?

    (5) When does an angel's guardianship of a man begin?

    (6) Whether the angel guardians always watch over men?

    (7) Whether the angel grieves over the loss of the one guarded?

    (8) Whether rivalry exists among the angels as regards their guardianship?
 
Article: 1 

Whether men are guarded by the angels?

  Objection 1: It would seem that men are not guarded by the angels. For guardians are deputed to some because they either know not how, or are not able, to guard themselves, as children and the sick. But man is able to guard himself by his free-will; and knows how by his natural knowledge of natural law. Therefore man is not guarded by an angel.

  Objection 2: Further, a strong guard makes a weaker one superfluous. But men are guarded by God, according to Ps. 120:4: "He shall neither slumber nor sleep, that keepeth Israel." Therefore man does not need to be guarded by an angel.

  Objection 3: Further, the loss of the guarded redounds to the negligence of the guardian; hence it was said to a certain one: "Keep this man; and if he shall slip away, thy life shall be for his life" (3 Kgs. 20:39). Now many perish daily through falling into sin; whom the angels could help by visible appearance, or by miracles, or in some such-like way. The angels would therefore be negligent if men are given to their guardianship. But that is clearly false. Therefore the angels are not the guardians of men.

  On the contrary, It is written (Ps. 90:11): "He hath given His angels charge over thee, to keep thee in all thy ways."

  I answer that, According to the plan of Divine Providence, we find that in all things the movable and variable are moved and regulated by the immovable and invariable; as all corporeal things by immovable spiritual substances, and the inferior bodies by the superior which are invariable in substance. We ourselves also are regulated as regards conclusions, about which we may have various opinions, by the principles which we hold in an invariable manner. It is moreover manifest that as regards things to be done human knowledge and affection can vary and fail from good in many ways; and so it was necessary that angels should be deputed for the guardianship of men, in order to regulate them and move them to good.

  Reply to Objection 1: By free-will man can avoid evil to a certain degree, but not in any sufficient degree; forasmuch as he is weak in affection towards good on account of the manifold passions of the soul. Likewise universal natural knowledge of the law, which by nature belongs to man, to a certain degree directs man to good, but not in a sufficient degree; because in the application of the universal principles of law to particular actions man happens to be deficient in many ways. Hence it is written (Wis. 9:14): "The thoughts of mortal men are fearful, and our counsels uncertain." Thus man needs to be guarded by the angels.

  Reply to Objection 2: Two things are required for a good action; first, that the affection be inclined to good, which is effected in us by the habit of mortal virtue. Secondly, that reason should discover the proper methods to make perfect the good of virtue; this the Philosopher (Ethic. vi) attributes to prudence. As regards the first, God guards man immediately by infusing into him grace and virtues; as regards the second, God guards man as his universal instructor, Whose precepts reach man by the medium of the angels, as above stated (Question [111], Article [1]).

  Reply to Objection 3: As men depart from the natural instinct of good by reason of a sinful passion, so also do they depart from the instigation of the good angels, which takes place invisibly when they enlighten man that he may do what is right. Hence that men perish is not to be imputed to the negligence of the angels but to the malice of men. That they sometimes appear to men visibly outside the ordinary course of nature comes from a special grace of God, as likewise that miracles occur outside the order of nature.

Whether each man is guarded by an angel?

  Objection 1: It would seem that each man is not guarded by an angel. For an angel is stronger than a man. But one man suffices to guard many men. Therefore much more can one angel guard many men.

  Objection 2: Further, the lower things are brought to God through the medium of the higher, as Dionysius says (Coel. Hier. iv, xiii). But as all the angels are unequal (Question [50], Article [4]), there is only one angel between whom and men there is no medium. Therefore there is only one angel who immediately keeps men.

  Objection 3: Further, the greater angels are deputed to the greater offices. But it is not a greater office to keep one man more than another; since all men are naturally equal. Since therefore of all the angels one is greater than another, as Dionysius says (Coel. Hier. x), it seems that different men are not guarded by different angels.

  On the contrary, On the text, "Their angels in heaven," etc. (Mt. 8:10), Jerome says: "Great is the dignity of souls, for each one to have an angel deputed to guard it from its birth."

  I answer that, Each man has an angel guardian appointed to him. This rests upon the fact that the guardianship of angels belongs to the execution of Divine providence concerning men. But God's providence acts differently as regards men and as regards other corruptible creatures, for they are related differently to incorruptibility. For men are not only incorruptible in the common species, but also in the proper forms of each individual, which are the rational souls, which cannot be said of other incorruptible things. Now it is manifest that the providence of God is chiefly exercised towards what remains for ever; whereas as regards things which pass away, the providence of God acts so as to order their existence to the things which are perpetual. Thus the providence of God is related to each man as it is to every genus or species of things corruptible. But, according to Gregory (Hom. xxxiv in Evang.), the different orders are deputed to the different "genera" of things, for instance, the "Powers" to coerce the demons, the "Virtues" to work miracles in things corporeal; while it is probable that the different species are presided over by different angels of the same order. Hence it is also reasonable to suppose that different angels are appointed to the guardianship of different men.

  Reply to Objection 1: A guardian may be assigned to a man for two reasons: first, inasmuch as a man is an individual, and thus to one man one guardian is due; and sometimes several are appointed to guard one. Secondly, inasmuch as a man is part of a community, and thus one man is appointed as guardian of a whole community; to whom it belongs to provide what concerns one man in his relation to the whole community, such as external works, which are sources of strength or weakness to others. But angel guardians are given to men also as regards invisible and occult things, concerning the salvation of each one in his own regard. Hence individual angels are appointed to guard individual men.

  Reply to Objection 2: As above stated (Question [112], Article [3], ad 4), all the angels of the first hierarchy are, as to some things, enlightened by God directly; but as to other things, only the superior are directly enlightened by God, and these reveal them to the inferior. And the same also applies to the inferior orders: for a lower angel is enlightened in some respects by one of the highest, and in other respects by the one immediately above him. Thus it is possible that some one angel enlightens a man immediately, and yet has other angels beneath him whom he enlightens.

  Reply to Objection 3: Although men are equal in nature, still inequality exists among them, according as Divine Providence orders some to the greater, and others to the lesser things, according to Ecclus. 33:11,12: "With much knowledge the Lord hath divided them, and diversified their ways: some of them hath He blessed and exalted, and some of them hath He cursed and brought low." Thus it is a greater office to guard one man than another.
 
Article: 3 

Whether to guard men belongs only to the lowest order of angels?

  Objection 1: It would seem that the guardianship of men does not belong only to the lowest order of the angels. For Chrysostom says that the text (Mt. 18:10), "Their angels in heaven," etc. is to be understood not of any angels but of the highest. Therefore the superior angels guard men.

  Objection 2: Further, the Apostle says that angels "are sent to minister for them who shall receive the inheritance of salvation" (Heb. 1:14); and thus it seems that the mission of the angels is directed to the guardianship of men. But five orders are sent in external ministry (Question [112], Article [4]). Therefore all the angels of the five orders are deputed to the guardianship of men.

  Objection 3: Further, for the guardianship of men it seems especially necessary to coerce the demons, which belongs most of all to the Powers, according to Gregory (Hom. xxxiv in Evang.); and to work miracles, which belongs to the Virtues. Therefore these orders are also deputed to the work of guardianship, and not only the lowest order.

  On the contrary, In the Psalm (90) the guardianship of men is attributed to the angels; who belong to the lowest order, according to Dionysius (Coel. Hier. v, ix).

  I answer that, As above stated (Article [2]), man is guarded in two ways; in one way by particular guardianship, according as to each man an angel is appointed to guard him; and such guardianship belongs to the lowest order of the angels, whose place it is, according to Gregory, to announce the "lesser things"; for it seems to be the least of the angelic offices to procure what concerns the salvation of only one man. The other kind of guardianship is universal, multiplied according to the different orders. For the more universal an agent is, the higher it is. Thus the guardianship of the human race belongs to the order of "Principalities," or perhaps to the "Archangels," whom we call the angel princes. Hence, Michael, whom we call an archangel, is also styled "one of the princes" (Dan. 10:13). Moreover all corporeal creatures are guarded by the "Virtues"; and likewise the demons by the "Powers," and the good spirits by the "Principalities," according to Gregory's opinion (Hom. xxxiv in Ev.).

  Reply to Objection 1: Chrysostom can be taken to mean the highest in the lowest order of angels; for, as Dionysius says (Coel. Hier. x) in each order there are first, middle, and last. It is, however, probable that the greater angels are deputed to keep those chosen by God for the higher degree of glory.

  Reply to Objection 2: Not all the angels who are sent have guardianship of individual men; but some orders have a universal guardianship, greater or less, as above explained.

  Reply to Objection 3: Even inferior angels exercise the office of the superior, as they share in their gifts, and they are executors of the superiors' power; and in this way all the angels of the lowest order can coerce the demons, and work miracles.

Article: 4 

Whether angels are appointed to the guardianship of all men?

  Objection 1: It would seem that angels are not appointed to the guardianship of all men. For it is written of Christ (Phil. 2:7) that "He was made in the likeness of men, and in habit found as a man." If therefore angels are appointed to the guardianship of all men, Christ also would have had an angel guardian. But this is unseemly, for Christ is greater than all the angels. Therefore angels are not appointed to the guardianship of all men.

  Objection 2: Further, Adam was the first of all men. But it was not fitting that he should have an angel guardian, at least in the state of innocence: for then he was not beset by any dangers. Therefore angels are not appointed to the guardianship of all men.

  Objection 3: Further, angels are appointed to the guardianship of men, that they may take them by the hand and guide them to eternal life, encourage them to good works, and protect them against the assaults of the demons. But men who are foreknown to damnation, never attain to eternal life. Infidels, also, though at times they perform good works, do not perform them well, for they have not a right intention: for "faith directs the intention" as Augustine says (Enarr. ii in Ps. 31). Moreover, the coming of Antichrist will be "according to the working of Satan," as it is written (2 Thess. 2:9). Therefore angels are not deputed to the guardianship of all men.

  On the contrary, is the authority of Jerome quoted above (Article [2]), for he says that "each soul has an angel appointed to guard it."

  I answer that, Man while in this state of life, is, as it were, on a road by which he should journey towards heaven. On this road man is threatened by many dangers both from within and from without, according to Ps. 159:4: "In this way wherein I walked, they have hidden a snare for me." And therefore as guardians are appointed for men who have to pass by an unsafe road, so an angel guardian is assigned to each man as long as he is a wayfarer. When, however, he arrives at the end of life he no longer has a guardian angel; but in the kingdom he will have an angel to reign with him, in hell a demon to punish him.

  Reply to Objection 1: Christ as man was guided immediately by the Word of God: wherefore He needed not be guarded by an angel. Again as regards His soul, He was a comprehensor, although in regard to His passible body, He was a wayfarer. In this latter respect it was right that He should have not a guardian angel as superior to Him, but a ministering angel as inferior to Him. Whence it is written (Mt. 4:11) that "angels came and ministered to Him."

  Reply to Objection 2: In the state of innocence man was not threatened by any peril from within: because within him all was well ordered, as we have said above (Question [95], Articles [1],3). But peril threatened from without on account of the snares of the demons; as was proved by the event. For this reason he needed a guardian angel.

  Reply to Objection 3: Just as the foreknown, the infidels, and even Anti-christ, are not deprived of the interior help of natural reason; so neither are they deprived of that exterior help granted by God to the whole human race---namely the guardianship of the angels. And although the help which they receive therefrom does not result in their deserving eternal life by good works, it does nevertheless conduce to their being protected from certain evils which would hurt both themselves and others. For even the demons are held off by the good angels, lest they hurt as much as they would. In like manner Antichrist will not do as much harm as he would wish.
 
Article: 5  

Whether an angel is appointed to guard a man from his birth?

  Objection 1: It would seem that an angel is not appointed to guard a man from his birth. For angels are "sent to minister for them who shall receive the inheritance of salvation," as the Apostle says (Heb. 1:14). But men begin to receive the inheritance of salvation, when they are baptized. Therefore an angel is appointed to guard a man from the time of his baptism, not of his birth.

  Objection 2: Further, men are guarded by angels in as far as angels enlighten and instruct them. But children are not capable of instruction as soon as they are born, for they have not the use of reason. Therefore angels are not appointed to guard children as soon as they are born.

  Objection 3: Further, a child has a rational soul for some time before birth, just as well as after. But it does not appear that an angel is appointed to guard a child before its birth, for they are not then admitted to the sacraments of the Church. Therefore angels are not appointed to guard men from the moment of their birth.

  On the contrary, Jerome says (vide A, 4) that "each soul has an angel appointed to guard it from its birth."

  I answer that, as Origen observes (Tract. v, super Matt.) there are two opinions on this matter. For some have held that the angel guardian is appointed at the time of baptism, others, that he is appointed at the time of birth. The latter opinion Jerome approves (vide A, 4), and with reason. For those benefits which are conferred by God on man as a Christian, begin with his baptism; such as receiving the Eucharist, and the like. But those which are conferred by God on man as a rational being, are bestowed on him at his birth, for then it is that he receives that nature. Among the latter benefits we must count the guardianship of angels, as we have said above (Articles [1],4). Wherefore from the very moment of his birth man has an angel guardian appointed to him.

  Reply to Objection 1: Angels are sent to minister, and that efficaciously indeed, for those who shall receive the inheritance of salvation, if we consider the ultimate effect of their guardianship, which is the realizing of that inheritance. But for all that, the angelic ministrations are not withdrawn for others although they are not so efficacious as to bring them to salvation: efficacious, nevertheless, they are, inasmuch as they ward off many evils.

  Reply to Objection 2: Guardianship is ordained to enlightenment by instruction, as to its ultimate and principal effect. Nevertheless it has many other effects consistent with childhood; for instance to ward off the demons, and to prevent both bodily and spiritual harm.

  Reply to Objection 3: As long as the child is in the mother's womb it is not entirely separate, but by reason of a certain intimate tie, is still part of her: just as the fruit while hanging on the tree is part of the tree. And therefore it can be said with some degree of probability, that the angel who guards the mother guards the child while in the womb. But at its birth, when it becomes separate from the mother, an angel guardian is appointed to it; as Jerome, above quoted, says.
 
Article: 6 

Whether the angel guardian ever forsakes a man?

  Objection 1: It would seem that the angel guardian sometimes forsakes the man whom he is appointed to guard. For it is said (Jer. 51:9) in the person of the angels: "We would have cured Babylon, but she is not healed: let us forsake her." And (Is. 5:5) it is written: "I will take away the hedge"---that is, "the guardianship of the angels" [gloss]---"and it shall be wasted."

  Objection 2: Further, God's guardianship excels that of the angels. But God forsakes man at times, according to Ps. 21:2: "O God, my God, look upon me: why hast Thou forsaken me?" Much rather therefore does an angel guardian forsake man.

  Objection 3: Further, according to Damascene (De Fide Orth. ii, 3), "When the angels are here with us, they are not in heaven." But sometimes they are in heaven. Therefore sometimes they forsake us.

  On the contrary, The demons are ever assailing us, according to 1 Pt. 5:8: "Your adversary the devil, as a roaring lion, goeth about, seeking whom he may devour." Much more therefore do the good angels ever guard us.

  I answer that, As appears above (Article [2]), the guardianship of the angels is an effect of Divine providence in regard to man. Now it is evident that neither man, nor anything at all, is entirely withdrawn from the providence of God: for in as far as a thing participates being, so far is it subject to the providence that extends over all being. God indeed is said to forsake man, according to the ordering of His providence, but only in so far as He allows man to suffer some defect of punishment or of fault. In like manner it must be said that the angel guardian never forsakes a man entirely, but sometimes he leaves him in some particular, for instance by not preventing him from being subject to some trouble, or even from falling into sin, according to the ordering of Divine judgments. In this sense Babylon and the House of Israel are said to have been forsaken by the angels, because their angel guardians did not prevent them from being subject to tribulation.

   From this the answers are clear to the first and second objections.

  Reply to Objection 3: Although an angel may forsake a man sometimes locally, he does not for that reason forsake him as to the effect of his guardianship: for even when he is in heaven he knows what is happening to man; nor does he need time for his local motion, for he can be with man in an instant.
 
Article: 7

Whether angels grieve for the ills of those whom they guard?

  Objection 1: It would seem that angels grieve for the ills of those whom they guard. For it is written (Is. 33:7): "The angels of peace shall weep bitterly." But weeping is a sign of grief and sorrow. Therefore angels grieve for the ills of those whom they guard.

  Objection 2: Further, according to Augustine (De Civ. Dei xiv, 15), "sorrow is for those things that happen against our will." But the loss of the man whom he has guarded is against the guardian angel's will. Therefore angels grieve for the loss of men.

  Objection 3: Further, as sorrow is contrary to joy, so penance is contrary to sin. But angels rejoice about one sinner doing penance, as we are told, Lk. 15:7. Therefore they grieve for the just man who falls into sin.

  Objection 4: Further, on Numbers 18:12: "Whatsoever first-fruits they offer," etc. the gloss of Origen says: "The angels are brought to judgment as to whether men have fallen through their negligence or through their own fault." But it is reasonable for anyone to grieve for the ills which have brought him to judgment. Therefore angels grieve for men's sins.

  On the contrary, Where there is grief and sorrow, there is not perfect happiness: wherefore it is written (Apoc. 21:4): "Death shall be no more, nor mourning, nor crying, nor sorrow." But the angels are perfectly happy. Therefore they have no cause for grief.

  I answer that, Angels do not grieve, either for sins or for the pains inflicted on men. For grief and sorrow, according to Augustine (De Civ. Dei xiv, 15) are for those things which occur against our will. But nothing happens in the world contrary to the will of the angels and the other blessed, because they will cleaves entirely to the ordering of Divine justice; while nothing happens in the world save what is effected or permitted by Divine justice. Therefore simply speaking, nothing occurs in the world against the will of the blessed. For as the Philosopher says (Ethic. iii, 1) that is called simply voluntary, which a man wills in a particular case, and at a particular time, having considered all the circumstances; although universally speaking, such a thing would not be voluntary: thus the sailor does not will the casting of his cargo into the sea, considered universally and absolutely, but on account of the threatened danger of his life, he wills it. Wherefore this is voluntary rather than involuntary, as stated in the same passage. Therefore universally and absolutely speaking the angels do not will sin and the pains inflicted on its account: but they do will the fulfilment of the ordering of Divine justice in this matter, in respect of which some are subjected to pains and are allowed to fall into sin.

  Reply to Objection 1: These words of Isaias may be understood of the angels, i.e. the messengers, of Ezechias, who wept on account of the words of Rabsaces, as related Is. 37:2 seqq.: this would be the literal sense. According to the allegorical sense the "angels of peace" are the apostles and preachers who weep for men's sins. If according to the anagogical sense this passage be expounded of the blessed angels, then the expression is metaphorical, and signifies that universally speaking the angels will the salvation of mankind: for in this sense we attribute passions to God and the angels.

   The reply to the second objection appears from what has been said.

  Reply to Objection 3: Both in man's repentance and in man's sin there is one reason for the angel's joy, namely the fulfilment of the ordering of the Divine Providence.

  Reply to Objection 4: The angels are brought into judgment for the sins of men, not as guilty, but as witnesses to convict man of weakness.
 
Article: 8

Whether there can be strife or discord among the angels?

  Objection 1: It would seem that there can be strife or discord among the angels. For it is written (Job 25:2): "Who maketh peace in His high places." But strife is opposed to peace. Therefore among the high angels there is no strife.

  Objection 2: Further, where there is perfect charity and just authority there can be no strife. But all this exists among the angels. Therefore there is no strife among the angels.

  Objection 3: Further, if we say that angels strive for those whom they guard, one angel must needs take one side, and another angel the opposite side. But if one side is in the right the other side is in the wrong. It will follow therefore, that a good angel is a compounder of wrong; which is unseemly. Therefore there is no strife among good angels.

  On the contrary, It is written (Dan. 10:13): "The prince of the kingdom of the Persians resisted me one and twenty days." But this prince of the Persians was the angel deputed to the guardianship of the kingdom of the Persians. Therefore one good angel resists the others; and thus there is strife among them.

  I answer that, The raising of this question is occasioned by this passage of Daniel. Jerome explains it by saying that the prince of the kingdom of the Persians is the angel who opposed the setting free of the people of Israel, for whom Daniel was praying, his prayers being offered to God by Gabriel. And this resistance of his may have been caused by some prince of the demons having led the Jewish captives in Persia into sin; which sin was an impediment to the efficacy of the prayer which Daniel put up for that same people.

   But according to Gregory (Moral. xvii), the prince of the kingdom of Persia was a good angel appointed to the guardianship of that kingdom. To see therefore how one angel can be said to resist another, we must note that the Divine judgments in regard to various kingdoms and various men are executed by the angels. Now in their actions, the angels are ruled by the Divine decree. But it happens at times in various kingdoms or various men there are contrary merits or demerits, so that one of them is subject to or placed over another. As to what is the ordering of Divine wisdom on such matters, the angels cannot know it unless God reveal it to them: and so they need to consult Divine wisdom thereupon. Wherefore forasmuch as they consult the Divine will concerning various contrary and opposing merits, they are said to resist one another: not that their wills are in opposition, since they are all of one mind as to the fulfilment of the Divine decree; but that the things about which they seek knowledge are in opposition.

   From this the answers to the objections are clear.

Question: 114 OF THE ASSAULTS OF THE DEMONS (FIVE ARTICLES)

   We now consider the assaults of the demons. Under this head there are five points of inquiry:

    (1) Whether men are assailed by the demons?

    (2) Whether to tempt is proper to the devil?

    (3) Whether all the sins of men are to be set down to the assaults or temptations of the demons?

    (4) Whether they can work real miracles for the purpose of leading men astray?

    (5) Whether the demons who are overcome by men, are hindered from making further assaults?
 
Article: 1 

Whether men are assailed by the demons?

  Objection 1: It would seem that men are not assailed by the demons. For angels are sent by God to guard man. But demons are not sent by God: for the demons' intention is the loss of souls; whereas God's is the salvation of souls. Therefore demons are not deputed to assail man.

  Objection 2: Further, it is not a fair fight, for the weak to be set against the strong, and the ignorant against the astute. But men are weak and ignorant, whereas the demons are strong and astute. It is not therefore to be permitted by God, the author of all justice, that men should be assailed by demons.

  Objection 3: Further, the assaults of the flesh and the world are enough for man's exercise. But God permits His elect to be assailed that they may be exercised. Therefore there is no need for them to be assailed by the demons.

  On the contrary, The Apostle says (Eph. 6:12): "Our wrestling is not against flesh and blood; but against Principalities and Powers, against the rulers of the world of this darkness, against the spirits of wickedness in the high places."

  I answer that, Two things may be considered in the assault of the demons---the assault itself, and the ordering thereof. The assault itself is due to the malice of the demons, who through envy endeavor to hinder man's progress; and through pride usurp a semblance of Divine power, by deputing certain ministers to assail man, as the angels of God in their various offices minister to man's salvation. But the ordering of the assault is from God, Who knows how to make orderly use of evil by ordering it to good. On the other hand, in regard to the angels, both their guardianship and the ordering thereof are to be referred to God as their first author.

  Reply to Objection 1: The wicked angels assail men in two ways. Firstly by instigating them to sin; and thus they are not sent by God to assail us, but are sometimes permitted to do so according to God's just judgments. But sometimes their assault is a punishment to man: and thus they are sent by God; as the lying spirit was sent to punish Achab, King of Israel, as is related in 3 Kgs. 22:20. For punishment is referred to God as its first author. Nevertheless the demons who are sent to punish, do so with an intention other than that for which they are sent; for they punish from hatred or envy; whereas they are sent by God on account of His justice.

  Reply to Objection 2: In order that the conditions of the fight be not unequal, there is as regards man the promised recompense, to be gained principally through the grace of God, secondarily through the guardianship of the angels. Wherefore (4 Kgs. 6:16), Eliseus said to his servant: "Fear not, for there are more with us than with them."

  Reply to Objection 3: The assault of the flesh and the world would suffice for the exercise of human weakness: but it does not suffice for the demon's malice, which makes use of both the above in assailing men. But by the Divine ordinance this tends to the glory of the elect.
 
Article: 2 

Whether to tempt is proper to the devil?

  Objection 1: It would seem that to tempt is not proper to the devil. For God is said to tempt, according to Gn. 22:1, "God tempted Abraham." Moreover man is tempted by the flesh and the world. Again, man is said to tempt God, and to tempt man. Therefore it is not proper to the devil to tempt.

  Objection 2: Further, to tempt is a sign of ignorance. But the demons know what happens among men. Therefore the demons do not tempt.

  Objection 3: Further, temptation is the road to sin. Now sin dwells in the will. Since therefore the demons cannot change man's will, as appears from what has been said above (Question [111], Article [2]), it seems that it is not in their province to tempt.

  On the contrary, It is written (1 Thess. 3:5): "Lest perhaps he that tempteth should have tempted you": to which the gloss adds, "that is, the devil, whose office it is to tempt."

  I answer that, To tempt is, properly speaking, to make trial of something. Now we make trial of something in order to know something about it: hence the immediate end of every tempter is knowledge. But sometimes another end, either good or bad, is sought to be acquired through that knowledge; a good end, when, for instance, one desires to know of someone, what sort of a man he is as to knowledge, or virtue, with a view to his promotion; a bad end, when that knowledge is sought with the purpose of deceiving or ruining him.

   From this we can gather how various beings are said to tempt in various ways. For man is said to tempt, sometimes indeed merely for the sake of knowing something; and for this reason it is a sin to tempt God; for man, being uncertain as it were, presumes to make an experiment of God's power. Sometimes too he tempts in order to help, sometimes in order to hurt. The devil, however, always tempts in order to hurt by urging man into sin. In this sense it is said to be his proper office to tempt: for thought at times man tempts thus, he does this as minister of the devil. God is said to tempt that He may know, in the same sense as that is said to know which makes others to know. Hence it is written (Dt. 13:3): "The Lord your God trieth you, that it may appear whether you love him."

   The flesh and the world are said to tempt as the instruments or matter of temptations; inasmuch as one can know what sort of man someone is, according as he follows or resists the desires of the flesh, and according as he despises worldly advantages and adversity: of which things the devil also makes use in tempting.

   Thus the reply to the first objection is clear.

  Reply to Objection 2: The demons know what happens outwardly among men; but the inward disposition of man God alone knows, Who is the "weigher of spirits" (Prov. 16:2). It is this disposition that makes man more prone to one vice than to another: hence the devil tempts, in order to explore this inward disposition of man, so that he may tempt him to that vice to which he is most prone.

  Reply to Objection 3: Although a demon cannot change the will, yet, as stated above (Question [111], Article [3]), he can change the inferior powers of man, in a certain degree: by which powers, though the will cannot be forced, it can nevertheless be inclined.
 
Article: 3 

Whether all sins are due to the temptation of the devil?

  Objection 1: It would seem that all sins are due to the temptation of the devil. For Dionysius says (Div. Nom. iv) that "the multitude of demons is the cause of all evils, both to themselves and to others." And Damascene says (De Fide Orth. ii, 4) that "all malice and all uncleanness have been devised by the devil."

  Objection 2: Further, of every sinner can be said what the Lord said of the Jews (Jn. 8:44): "You are of your father the devil." But this was in as far as they sinned through the devil's instigation. Therefore every sin is due to the devil's instigation.

  Objection 3: Further, as angels are deputed to guard men, so demons are deputed to assail men. But every good thing we do is due to the suggestion of the good angels: because the Divine gifts are borne to us by the angels. Therefore all the evil we do, is due to the instigation of the devil.

  On the contrary, It is written (De Eccl. Dogmat. xlix): "Not all our evil thoughts are stirred up by the devil, but sometimes they arise from the movement of our free-will."

  I answer that, One thing can be the cause of another in two ways; directly and indirectly. Indirectly as when an agent is the cause of a disposition to a certain effect, it is said to be the occasional and indirect cause of that effect: for instance, we might say that he who dries the wood is the cause of the wood burning. In this way we must admit that the devil is the cause of all our sins; because he it was who instigated the first man to sin, from whose sin there resulted a proneness to sin in the whole human race: and in this sense we must take the words of Damascene and Dionysius.

   But a thing is said to be the direct cause of something, when its action tends directly thereunto. And in this way the devil is not the cause of every sin: for all sins are not committed at the devil's instigation, but some are due to the free-will and the corruption of the flesh. For, as Origen says (Peri Archon iii), even if there were no devil, men would have the desire for food and love and such like pleasures; with regard to which many disorders may arise unless those desires are curbed by reason, especially if we presuppose the corruption of our natures. Now it is in the power of the free-will to curb this appetite and keep it in order. Consequently there is no need for all sins to be due to the instigation of the devil. But those sins which are due thereto man perpetrates "through being deceived by the same blandishments as were our first parents," as Isidore says (De Summo Bono ii).

   Thus the answer to the first objection is clear.

  Reply to Objection 2: When man commits sin without being thereto instigated by the devil, he nevertheless becomes a child of the devil thereby, in so far as he imitates him who was the first to sin.

  Reply to Objection 3: Man can of his own accord fall into sin: but he cannot advance in merit without the Divine assistance, which is borne to man by the ministry of the angels. For this reason the angels take part in all our good works: whereas all our sins are not due to the demons' instigation. Nevertheless there is no kind of sin which is not sometimes due to the demons' suggestion.

Whether demons can lead men astray by means of real miracles?

  Objection 1: It would seem that the demons cannot lead men astray by means of real miracles. For the activity of the demons will show itself especially in the works of Antichrist. But as the Apostle says (2 Thess. 2:9), his "coming is according to the working of Satan, in all power, and signs, and lying wonders." Much more therefore at other times do the demons perform lying wonders.

  Objection 2: Further, true miracles are wrought by some corporeal change. But demons are unable to change the nature of a body; for Augustine says (De Civ. Dei xviii, 18): "I cannot believe that the human body can receive the limbs of a beast by means of a demon's art or power." Therefore the demons cannot work real miracles.

  Objection 3: Further, an argument is useless which may prove both ways. If therefore real miracles can be wrought by demons, to persuade one of what is false, they will be useless to confirm the teaching of the faith. This is unfitting; for it is written (Mk. 16:20): "The Lord working withal, and confirming the word with signs that followed."

  On the contrary, Augustine says (Question [83]; [*Lib. xxi, Sent. sent 4, among the supposititious works of St. Augustine]): "Often by means of the magic art miracles are wrought like those which are wrought by the servants of God."

  I answer that, As is clear from what has been said above (Question [110], Article [4]), if we take a miracle in the strict sense, the demons cannot work miracles, nor can any creature, but God alone: since in the strict sense a miracle is something done outside the order of the entire created nature, under which order every power of a creature is contained. But sometimes miracle may be taken in a wide sense, for whatever exceeds the human power and experience. And thus demons can work miracles, that is, things which rouse man's astonishment, by reason of their being beyond his power and outside his sphere of knowledge. For even a man by doing what is beyond the power and knowledge of another, leads him to marvel at what he has done, so that in a way he seems to that man to have worked a miracle.

   It is to be noted, however, that although these works of demons which appear marvelous to us are not real miracles, they are sometimes nevertheless something real. Thus the magicians of Pharaoh by the demons' power produced real serpents and frogs. And "when fire came down from heaven and at one blow consumed Job's servants and sheep; when the storm struck down his house and with it his children---these were the work of Satan, not phantoms"; as Augustine says (De Civ. Dei xx, 19).

  Reply to Objection 1: As Augustine says in the same place, the works of Antichrist may be called lying wonders, "either because he will deceive men's senses by means of phantoms, so that he will not really do what he will seem to do; or because, if he work real prodigies, they will lead those into falsehood who believe in him."

  Reply to Objection 2: As we have said above (Question [110], Article [2]), corporeal matter does not obey either good or bad angels at their will, so that demons be able by their power to transmute matter from one form to another; but they can employ certain seeds that exist in the elements of the world, in order to produce these effects, as Augustine says (De Trin. iii, 8,9). Therefore it must be admitted that all the transformation of corporeal things which can be produced by certain natural powers, to which we must assign the seeds above mentioned, can alike be produced by the operation of the demons, by the employment of these seeds; such as the transformation of certain things into serpents or frogs, which can be produced by putrefaction. On the contrary, those transformations which cannot be produced by the power of nature, cannot in reality be effected by the operation of the demons; for instance, that the human body be changed into the body of a beast, or that the body of a dead man return to life. And if at times something of this sort seems to be effected by the operation of demons, it is not real but a mere semblance of reality.

   Now this may happen in two ways. Firstly, from within; in this way a demon can work on man's imagination and even on his corporeal senses, so that something seems otherwise that it is, as explained above (Question [111], Articles [3],4). It is said indeed that this can be done sometimes by the power of certain bodies. Secondly, from without: for just as he can from the air form a body of any form and shape, and assume it so as to appear in it visibly: so, in the same way he can clothe any corporeal thing with any corporeal form, so as to appear therein. This is what Augustine says (De Civ. Dei xviii, 18): "Man's imagination, which whether thinking or dreaming, takes the forms of an innumerable number of things, appears to other men's senses, as it were embodied in the semblance of some animal." This not to be understood as though the imagination itself or the images formed therein were identified with that which appears embodied to the senses of another man: but that the demon, who forms an image in a man's imagination, can offer the same picture to another man's senses.

  Reply to Objection 3: As Augustine says (Questions. 83, qu. 79): "When magicians do what holy men do, they do it for a different end and by a different right. The former do it for their own glory; the latter, for the glory of God: the former, by certain private compacts; the latter by the evident assistance and command of God, to Whom every creature is subject."

Whether a demon who is overcome by man, is for this reason hindered from making further assaults?

  Objection 1: It would seem that a demon who is overcome by a man, is not for that reason hindered from any further assault. For Christ overcame the tempter most effectively. Yet afterwards the demon assailed Him by instigating the Jews to kill Him. Therefore it is not true that the devil when conquered ceases his assaults.

  Objection 2: Further, to inflict punishment on one who has been worsted in a fight, is to incite him to a sharper attack. But this is not befitting God's mercy. Therefore the conquered demons are not prevented from further assaults.

  On the contrary, It is written (Mt. 4:11): "Then the devil left Him," i.e. Christ Who overcame.

  I answer that, Some say that when once a demon has been overcome he can no more tempt any man at all, neither to the same nor to any other sin. And others say that he can tempt others, but not the same man. This seems more probable as long as we understand it to be so for a certain definite time: wherefore (Lk. 4:13) it is written: "All temptation being ended, the devil departed from Him for a time." There are two reasons for this. One is on the part of God's clemency; for as Chrysostom says (Super Matt. Hom. v) [*In the Opus Imperfectum, among his supposititious works], "the devil does not tempt man for just as long as he likes, but for as long as God allows; for although He allows him to tempt for a short time, He orders him off on account of our weakness." The other reason is taken from the astuteness of the devil. As to this, Ambrose says on Lk. 4:13: "The devil is afraid of persisting, because he shrinks from frequent defeat." That the devil does nevertheless sometimes return to the assault, is apparent from Mt. 12:44: "I will return into my house from whence I came out."

   From what has been said, the objections can easily be solved.

Question: 115  OF THE ACTION OF THE CORPOREAL CREATURE (SIX ARTICLES)

   We have now to consider the action of the corporeal creature; and fate, which is ascribed to certain bodies. Concerning corporeal actions there are six points of inquiry:

    (1) Whether a body can be active?

    (2) Whether there exist in bodies certain seminal virtues?

    (3) Whether the heavenly bodies are the causes of what is done here by the inferior bodies?

    (4) Whether they are the cause of human acts?

    (5) Whether demons are subject to their influence?

    (6) Whether the heavenly bodies impose necessity on those things which are subject to their influence?
 
Article: 1 

Whether a body can be active?

  Objection 1: It would seem that no bodies are active. For Augustine says (De Civ. Dei v, 9): "There are things that are acted upon, but do not act; such are bodies: there is one Who acts but is not acted upon; this is God: there are things that both act and are acted upon; these are the spiritual substances."

  Objection 2: Further, every agent except the first agent requires in its work a subject susceptible of its action. But there is not substance below the corporeal substance which can be susceptible of the latter's action; since it belongs to the lowest degree of beings. Therefore corporeal substance is not active.

  Objection 3: Further, every corporeal substance is limited by quantity. But quantity hinders substance from movement and action, because it surrounds it and penetrates it: just as a cloud hinders the air from receiving light. A proof of this is that the more a body increases in quantity, the heavier it is and the more difficult to move. Therefore no corporeal substance is active.

  Objection 4: Further, the power of action in every agent is according to its propinquity to the first active cause. But bodies, being most composite, are most remote from the first active cause, which is most simple. Therefore no bodies are active.

  Objection 5: Further, if a body is an agent, the term of its action is either a substantial, or an accidental form. But it is not a substantial form; for it is not possible to find in a body any principle of action, save an active quality, which is an accident; and an accident cannot be the cause of a substantial form, since the cause is always more excellent than the effect. Likewise, neither is it an accidental form, for "an accident does not extend beyond its subject," as Augustine says (De Trin. ix, 4). Therefore no bodies are active.

  On the contrary, Dionysius says (Coel. Hier. xv) that among other qualities of corporeal fire, "it shows its greatness in its action and power on that of which it lays hold."

  I answer that, It is apparent to the senses that some bodies are active. But concerning the action of bodies there have been three errors. For some denied all action to bodies. This is the opinion of Avicebron in his book on The Fount of Life, where, by the arguments mentioned above, he endeavors to prove that no bodies act, but that all the actions which seem to be the actions of bodies, are the actions of some spiritual power that penetrates all bodies: so that, according to him, it is not fire that heats, but a spiritual power which penetrates, by means of the fire. And this opinion seems to be derived from that of Plato. For Plato held that all forms existing in corporeal matter are participated thereby, and determined and limited thereto; and that separate forms are absolute and as it were universal; wherefore he said that these separate forms are the causes of forms that exist in matter. Therefore inasmuch as the form which is in corporeal matter is determined to this matter individualized by quantity, Avicebron held that the corporeal form is held back and imprisoned by quantity, as the principle of individuality, so as to be unable by action to extend to any other matter: and that the spiritual and immaterial form alone, which is not hedged in by quantity, can issue forth by acting on something else.

   But this does not prove that the corporeal form is not an agent, but that it is not a universal agent. For in proportion as a thing is participated, so, of necessity, must that be participated which is proper thereto; thus in proportion to the participation of light is the participation of visibility. But to act, which is nothing else than to make something to be in act, is essentially proper to an act as such; wherefore every agent produces its like. So therefore to the fact of its being a form not determined by matter subject to quantity, a thing owes its being an agent indeterminate and universal: but to the fact that it is determined to this matter, it owes its being an agent limited and particular. Wherefore if the form of fire were separate, as the Platonists supposed, it would be, in a fashion, the cause of every ignition. But this form of fire which is in this corporeal matter, is the cause of this ignition which passes from this body to that. Hence such an action is effected by the contact of two bodies.

   But this opinion of Avicebron goes further than that of Plato. For Plato held only substantial forms to be separate; while he referred accidents to the material principles which are "the great" and "the small," which he considered to be the first contraries, by others considered to the "the rare" and "the dense." Consequently both Plato and Avicenna, who follows him to a certain extent, held that corporeal agents act through their accidental forms, by disposing matter for the substantial form; but that the ultimate perfection attained by the introduction of the substantial form is due to an immaterial principle. And this is the second opinion concerning the action of bodies; of which we have spoken above when treating of the creation (Question [45], Article [8]).

   The third opinion is that of Democritus, who held that action takes place through the issue of atoms from the corporeal agent, while passion consists in the reception of the atoms in the pores of the passive body. This opinion is disproved by Aristotle (De Gener. i, 8,9). For it would follow that a body would not be passive as a whole, and the quantity of the active body would be diminished through its action; which things are manifestly untrue.

   We must therefore say that a body acts forasmuch as it is in act, on a body forasmuch as it is in potentiality.

  Reply to Objection 1: This passage of Augustine is to be understood of the whole corporeal nature considered as a whole, while thus has no nature inferior to it, on which it can act; as the spiritual nature acts on the corporeal, and the uncreated nature on the created. Nevertheless one body is inferior to another, forasmuch as it is in potentiality to that which the other has in act.

   From this follows the solution of the second objection. But it must be observed, when Avicebron argues thus, "There is a mover who is not moved, to wit, the first maker of all; therefore, on the other hand, there exists something moved which is purely passive," that this is to be conceded. But this latter is primary matter, which is a pure potentiality, just as God is pure act. Now a body is composed of potentiality and act; and therefore it is both active and passive.

  Reply to Objection 3: Quantity does not entirely hinder the corporeal form from action, as stated above; but from being a universal agent, forasmuch as a form is individualized through being in matter subject to quantity. The proof taken from the weight of bodies is not to the purpose. First, because addition of quantity does not cause weight; as is proved (De Coelo et Mundo iv, 2). Secondly, it is false that weight retards movement; on the contrary, the heavier a thing, the greater its movement, if we consider the movement proper thereto. Thirdly, because action is not effected by local movement, as Democritus held: but by something being reduced from potentiality to act.

  Reply to Objection 4: A body is not that which is most distant from God; for it participates something of a likeness to the Divine Being, forasmuch as it has a form. That which is most distant from God is primary matter; which is in no way active, since it is a pure potentiality.

  Reply to Objection 5: The term of a body's action is both an accidental form and a substantial form. For the active quality, such as heat, although itself an accident, acts nevertheless by virtue of the substantial form, as its instrument: wherefore its action can terminate in a substantial form; thus natural heat, as the instrument of the soul, has an action terminating in the generation of flesh. But by its own virtue it produces an accident. Nor is it against the nature of an accident to surpass its subject in acting, but it is to surpass it in being; unless indeed one were to imagine that an accident transfers its identical self from the agent to the patient; thus Democritus explained action by an issue of atoms.

Article: 2  

Whether there are any seminal virtues in corporeal matter?

  Objection 1: It would seem that there are no seminal virtues in corporeal matter. For virtue [ratio] implies something of a spiritual order. But in corporeal matter nothing exists spiritually, but only materially, that is, according to the mode of that in which it is. Therefore there are no seminal virtues in corporeal matter.

  Objection 2: Further, Augustine (De Trin. iii, 8,9) says that demons produce certain results by employing with a hidden movement certain seeds, which they know to exist in matter. But bodies, not virtues, can be employed with local movement. Therefore it is unreasonable to say that there are seminal virtues in corporeal matter.

  Objection 3: Further, seeds are active principles. But there are no active principles in corporeal matter; since, as we have said above, matter is not competent to act (Article [1], ad 2,4). Therefore there are no seminal virtues in corporeal matter.

  Objection 4: Further, there are said to be certain "causal virtues" (Augustine, De Gen. ad lit. v, 4) which seem to suffice for the production of things. But seminal virtues are not causal virtues: for miracles are outside the scope of seminal virtues, but not of causal virtues. Therefore it is unreasonable to say that there are seminal virtues in corporeal matter.

  On the contrary, Augustine says (De Trin. iii, 8): "Of all the things which are generated in a corporeal and visible fashion, certain seeds lie hidden in the corporeal things of this world."

  I answer that, It is customary to name things after what is more perfect, as the Philosopher says (De Anima ii, 4). Now in the whole corporeal nature, living bodies are the most perfect: wherefore the word "nature" has been transferred from living things to all natural things. For the word itself, "nature," as the Philosopher says (Metaph. v, Did. iv, 4), was first applied to signify the generation of living things, which is called "nativity": and because living things are generated from a principle united to them, as fruit from a tree, and the offspring from the mother, to whom it is united, consequently the word "nature" has been applied to every principle of movement existing in that which is moved. Now it is manifest that the active and passive principles of the generation of living things are the seeds from which living things are generated. Therefore Augustine fittingly gave the name of "seminal virtues" [seminales rationes] to all those active and passive virtues which are the principles of natural generation and movement.

   These active and passive virtues may be considered in several orders. For in the first place, as Augustine says (Gen. ad lit. vi, 10), they are principally and originally in the Word of God, as "typal ideas." Secondly, they are in the elements of the world, where they were produced altogether at the beginning, as in "universal causes." Thirdly, they are in those things which, in the succession of time, are produced by universal causes, for instance in this plant, and in that animal, as in "particular causes." Fourthly, they are in the "seeds" produced from animals and plants. And these again are compared to further particular effects, as the primordial universal causes to the first effects produced.

  Reply to Objection 1: These active and passive virtues of natural things, thought not called "virtues" [rationes] by reason of their being in corporeal matter, can nevertheless be so called in respect of their origin, forasmuch as they are the effect of the typal ideas [rationes ideales].

  Reply to Objection 2: These active and passive virtues are in certain parts of corporeal things: and when they are employed with local movement for the production of certain results, we speak of the demons as employing seeds.

  Reply to Objection 3: The seed of the male is the active principle in the generation of an animal. But that can be called seed also which the female contributes as the passive principle. And thus the word "seed" covers both active and passive principles.

  Reply to Objection 4: From the words of Augustine when speaking of these seminal virtues, it is easy to gather that they are also causal virtues, just as seed is a kind of cause: for he says (De Trin. iii, 9) that, "as a mother is pregnant with the unborn offspring, so is the world itself pregnant with the causes of unborn things." Nevertheless, the "typal ideas" can be called "causal virtues," but not, strictly speaking, "seminal virtues," because seed is not a separate principle; and because miracles are not wrought outside the scope of causal virtues. Likewise neither are miracles wrought outside the scope of the passive virtues so implanted in the creature, that the latter can be used to any purpose that God commands. But miracles are said to be wrought outside the scope of the natural active virtues, and the passive potentialities which are ordered to such active virtues, and this is what is meant when we say that they are wrought outside the scope of seminal virtues.

Whether the heavenly bodies are the cause of what is produced in bodies here below?

  Objection 1: It would seem that the heavenly bodies are not the cause of what is produced in bodies here below. For Damascene says (De Fide Orth. ii, 7): "We say that they"---namely, the heavenly bodies---"are not the cause of generation or corruption: they are rather signs of storms and atmospheric changes."

  Objection 2: Further, for the production of anything, an agent and matter suffice. But in things here below there is passive matter; and there are contrary agents---heat and cold, and the like. Therefore for the production of things here below, there is no need to ascribe causality to the heavenly bodies.

  Objection 3: Further, the agent produces its like. Now it is to be observed that everything which is produced here below is produced through the action of heat and cold, moisture and dryness, and other such qualities, which do not exist in heavenly bodies. Therefore the heavenly bodies are not the cause of what is produced here below.

  Objection 4: Further, Augustine says (De Civ. Dei v, 6): "Nothing is more corporeal than sex." But sex is not caused by the heavenly bodies: a sign of this is that of twins born under the same constellation, one may be male, the other female. Therefore the heavenly bodies are not the cause of things produced in bodies here below.

  On the contrary, Augustine says (De Trin. iii, 4): "Bodies of a grosser and inferior nature are ruled in a certain order by those of a more subtle and powerful nature." And Dionysius (Div. Nom. iv) says that "the light of the sun conduces to the generation of sensible bodies, moves them to life, gives them nourishment, growth, and perfection."

  I answer that, Since every multitude proceeds from unity; and since what is immovable is always in the same way of being, whereas what is moved has many ways of being: it must be observed that throughout the whole of nature, all movement proceeds from the immovable. Therefore the more immovable certain things are, the more are they the cause of those things which are most movable. Now the heavenly bodies are of all bodies the most immovable, for they are not moved save locally. Therefore the movements of bodies here below, which are various and multiform, must be referred to the movement of the heavenly bodies, as to their cause.

  Reply to Objection 1: These words of Damascene are to be understood as denying that the heavenly bodies are the first cause of generation and corruption here below; for this was affirmed by those who held that the heavenly bodies are gods.

  Reply to Objection 2: The active principles of bodies here below are only the active qualities of the elements, such as hot and cold and the like. If therefore the substantial forms of inferior bodies were not diversified save according to accidents of that kind, the principles of which the early natural philosophers held to be the "rare" and the "dense"; there would be no need to suppose some principle above these inferior bodies, for they would be of themselves sufficient to act. But to anyone who considers the matter aright, it is clear that those accidents are merely material dispositions in regard to the substantial forms of natural bodies. Now matter is not of itself sufficient to act. And therefore it is necessary to suppose some active principle above these material dispositions.

   This is why the Platonists maintained the existence of separate species, by participation of which the inferior bodies receive their substantial forms. But this does not seem enough. For the separate species, since they are supposed to be immovable, would always have the same mode of being: and consequently there would be no variety in the generation and corruption of inferior bodies: which is clearly false.

   Therefore it is necessary, as the Philosopher says (De Gener. ii, 10), to suppose a movable principle, which by reason of its presence or absence causes variety in the generation and corruption of inferior bodies. Such are the heavenly bodies. Consequently whatever generates here below, moves to the production of the species, as the instrument of a heavenly body: thus the Philosopher says (Phys. ii, 2) that "man and the sun generate man."

  Reply to Objection 3: The heavenly bodies have not a specific likeness to the bodies here below. Their likeness consists in this, that by reason of their universal power, whatever is generated in inferior bodies, is contained in them. In this way also we say that all things are like God.

  Reply to Objection 4: The actions of heavenly bodies are variously received in inferior bodies, according to the various dispositions of matter. Now it happens at times that the matter in the human conception is not wholly disposed to the male sex; wherefore it is formed sometimes into a male, sometimes into a female. Augustine quotes this as an argument against divination by stars: because the effects of the stars are varied even in corporeal things, according to the various dispositions of matter.

Whether the heavenly bodies are the cause of human actions?

  Objection 1: It would seem that the heavenly bodies are the cause of human actions. For since the heavenly bodies are moved by spiritual substances, as stated above (Question [110], Article [3]), they act by virtue thereof as their instruments. But those spiritual substances are superior to our souls. Therefore it seems that they can cause impressions on our souls, and thereby cause human actions.

  Objection 2: Further, every multiform is reducible to a uniform principle. But human actions are various and multiform. Therefore it seems that they are reducible to the uniform movements of heavenly bodies, as to their principles.

  Objection 3: Further, astrologers often foretell the truth concerning the outcome of wars, and other human actions, of which the intellect and will are the principles. But they could not do this by means of the heavenly bodies, unless these were the cause of human actions. Therefore the heavenly bodies are the cause of human actions.

  On the contrary, Damascene says (De Fide Orth. ii, 7) that "the heavenly bodies are by no means the cause of human actions."

  I answer that, The heavenly bodies can directly and of themselves act on bodies, as stated above (Article [3]). They can act directly indeed on those powers of the soul which are the acts of corporeal organs, but accidentally: because the acts of such powers must needs be hindered by obstacles in the organs; thus an eye when disturbed cannot see well. Wherefore if the intellect and will were powers affixed to corporeal organs, as some maintained, holding that intellect does not differ from sense; it would follow of necessity that the heavenly bodies are the cause of human choice and action. It would also follow that man is led by natural instinct to his actions, just as other animals, in which there are powers other than those which are affixed to corporeal organs: for whatever is done here below in virtue of the action of heavenly bodies, is done naturally. It would therefore follow that man has no free-will, and that he would have determinate actions, like other natural things. All of which is manifestly false, and contrary to human habit. It must be observed, however, that indirectly and accidentally, the impressions of heavenly bodies can reach the intellect and will, forasmuch, namely, as both intellect and will receive something from the inferior powers which are affixed to corporeal organs. But in this the intellect and will are differently situated. For the intellect, of necessity, receives from the inferior apprehensive powers: wherefore if the imaginative, cogitative, or memorative powers be disturbed, the action of the intellect is, of necessity, disturbed also. The will, on the contrary, does not, of necessity, follow the inclination of the inferior appetite; for although the passions in the irascible and concupiscible have a certain force in inclining the will; nevertheless the will retains the power of following the passions or repressing them. Therefore the impressions of the heavenly bodies, by virtue of which the inferior powers can be changed, has less influence on the will, which is the proximate cause of human actions, than on the intellect.

   To maintain therefore that heavenly bodies are the cause of human actions is proper to those who hold that intellect does not differ from sense. Wherefore some of these said that "such is the will of men, as is the day which the father of men and of gods brings on" (Odyssey xviii 135). Since, therefore, it is manifest that intellect and will are not acts of corporeal organs, it is impossible that heavenly bodies be the cause of human actions.

  Reply to Objection 1: The spiritual substances, that move the heavenly bodies, do indeed act on corporeal things by means of the heavenly bodies; but they act immediately on the human intellect by enlightening it. On the other hand, they cannot compel the will, as stated above (Question [111], Article [2]).

  Reply to Objection 2: Just as the multiformity of corporeal movements is reducible to the uniformity of the heavenly movement as to its cause: so the multiformity of actions proceeding from the intellect and the will is reduced to a uniform principle which is the Divine intellect and will.

  Reply to Objection 3: The majority of men follow their passions, which are movements of the sensitive appetite, in which movements of the heavenly bodies can cooperate: but few are wise enough to resist these passions. Consequently astrologers are able to foretell the truth in the majority of cases, especially in a general way. But not in particular cases; for nothing prevents man resisting his passions by his free-will. Wherefore the astrologers themselves are wont to say that "the wise man is stronger than the stars" [*Ptolemy, Centiloquium, prop. 5], forasmuch as, to wit, he conquers his passions.
 
Article: 5

Whether heavenly bodies can act on the demons?

  Objection 1: It would seem that heavenly bodies can act on the demons. For the demons, according to certain phases of the moon, can harass men, who on that account are called lunatics, as appears from Mt. 4:24 and 17:14. But this would not be if they were not subject to the heavenly bodies. Therefore the demons are subject to them.

  Objection 2: Further, necromancers observe certain constellations in order to invoke the demons. But these would not be invoked through the heavenly bodies unless they were subject to them. Therefore they are subject to them.

  Objection 3: Further, heavenly bodies are more powerful than inferior bodies. But the demons are confined to certain inferior bodies, namely, "herbs, stones, animals, and to certain sounds and words, forms and figures," as Porphyry says, quoted by Augustine (De Civ. Dei x, 11). Much more therefore are the demons subject to the action of heavenly bodies.

  On the contrary, The demons are superior in the order of nature, to the heavenly bodies. But the "agent is superior to the patient," as Augustine says (Gen. ad lit. xii, 16). Therefore the demons are not subject to the action of heavenly bodies.

  I answer that, There have been three opinions about the demons. In the first place the Peripatetics denied the existence of demons; and held that what is ascribed to the demons, according to the necromantic art, is effected by the power of the heavenly bodies. This is what Augustine (De Civ. Dei x, 11) relates as having been held by Porphyry, namely, that "on earth men fabricate certain powers useful in producing certain effects of the stars." But this opinion is manifestly false. For we know by experience that many things are done by demons, for which the power of heavenly bodies would in no way suffice: for instance, that a man in a state of delirium should speak an unknown tongue, recite poetry and authors of whom he has no previous knowledge; that necromancers make statues to speak and move, and other like things.

   For this reason the Platonists were led to hold that demons are "animals with an aerial body and a passive soul," as Apuleius says, quoted by Augustine (De Civ. Dei viii, 16). And this is the second of the opinions mentioned above: according to which it could be said that demons are subject to heavenly bodies in the same way as we have said man is subject thereto (Article [4]). But this opinion is proved to be false from what we have said above (Question [51], Article [1]): for we hold that demons are spiritual substances not united to bodies. Hence it is clear that they are subject to the action of heavenly bodies neither essentially nor accidentally, neither directly nor indirectly.

  Reply to Objection 1: That demons harass men, according to certain phases of the moon, happens in two ways. Firstly, they do so in order to "defame God's creature," namely, the moon; as Jerome (In Matt. iv, 24) and Chrysostom (Hom. lvii in Matt.) say. Secondly, because as they are unable to effect anything save by means of the natural forces, as stated above (Question [114], Article [4], ad 2) they take into account the aptitude of bodies for the intended result. Now it is manifest that "the brain is the most moist of all the parts of the body," as Aristotle says [*De Part. Animal. ii, 7: De Sens. et Sensato ii: De Somn. et Vigil. iii]: wherefore it is the most subject to the action of the moon, the property of which is to move what is moist. And it is precisely in the brain that animal forces culminate: wherefore the demons, according to certain phases of the moon, disturb man's imagination, when they observe that the brain is thereto disposed.

  Reply to Objection 2: Demons when summoned through certain constellations, come for two reasons. Firstly, in order to lead man into the error of believing that there is some Divine power in the stars. Secondly, because they consider that under certain constellations corporeal matter is better disposed for the result for which they are summoned.

  Reply to Objection 3: As Augustine says (De Civ. Dei xxi, 6), the "demons are enticed through various kinds of stones, herbs, trees, animals, songs, rites, not as an animal is enticed by food, but as a spirit by signs"; that is to say, forasmuch as these things are offered to them in token of the honor due to God, of which they are covetous.

Whether heavenly bodies impose necessity on things subject to their action?

  Objection 1: It would seem that heavenly bodies impose necessity on things subject to their action. For given a sufficient cause, the effect follows of necessity. But heavenly bodies are a sufficient cause of their effects. Since, therefore, heavenly bodies, with their movements and dispositions, are necessary beings; it seems that their effects follow of necessity.

  Objection 2: Further, an agent's effect results of necessity in matter, when the power of the agent is such that it can subject the matter to itself entirely. But the entire matter of inferior bodies is subject to the power of heavenly bodies, since this is a higher power than theirs. Therefore the effect of the heavenly bodies is of necessity received in corporeal matter.

  Objection 3: Further, if the effect of the heavenly body does not follow of necessity, this is due to some hindering cause. But any corporeal cause, that might possibly hinder the effect of a heavenly body, must of necessity be reducible to some heavenly principle: since the heavenly bodies are the causes of all that takes place here below. Therefore, since also that heavenly principle is necessary, it follows that the effect of the heavenly body is necessarily hindered. Consequently it would follow that all that takes place here below happens of necessity.

  On the contrary, The Philosopher says (De Somn. et Vigil. [*De Divin. per Somn. ii]): "It is not incongruous that many of the signs observed in bodies, of occurrences in the heavens, such as rain and wind, should not be fulfilled." Therefore not all the effects of heavenly bodies take place of necessity.

  I answer that, This question is partly solved by what was said above (Article [4]); and in part presents some difficulty. For it was shown that although the action of heavenly bodies produces certain inclinations in corporeal nature, the will nevertheless does not of necessity follow these inclinations. Therefore there is nothing to prevent the effect of heavenly bodies being hindered by the action of the will, not only in man himself, but also in other things to which human action extends.

   But in natural things there is no such principle, endowed with freedom to follow or not to follow the impressions produced by heavenly agents. Wherefore it seems that in such things at least, everything happens of necessity; according to the reasoning of some of the ancients who supposing that everything that is, has a cause; and that, given the cause, the effect follows of necessity; concluded that all things happen of necessity. This opinion is refuted by Aristotle (Metaph. vi, Did. v, 3) as to this double supposition.

   For in the first place it is not true that, given any cause whatever, the effect must follow of necessity. For some causes are so ordered to their effects, as to produce them, not of necessity, but in the majority of cases, and in the minority to fail in producing them. But that such cases do fail in the minority of cases is due to some hindering cause; consequently the above-mentioned difficulty seems not to be avoided, s
