Summa Th. II-II EN Qu.156 a.2
Objection: 1. It would seem that incontinence is not a sin. For as Augustine says (De Lib. Arb. iii, 18): "No man sins in what he cannot avoid." Now no man can by himself avoid incontinence, according to Sg 8,21, "I know [Vulg.: 'knew'] that I could not . . . be continent, except God gave it." Therefore incontinence is not a sin.
2. Further, apparently every sin originates in the reason. But the judgment of reason is overcome in the incontinent man. Therefore incontinence is not a sin.
3. Further, no one sins in loving God vehemently. Now a man becomes incontinent through the vehemence of divine love: for Dionysius says (Div. Nom. iv) that "Paul, through incontinence of divine love, exclaimed: I live, now not I" (Ga 2,20). Therefore incontinence is not a sin.
On the contrary It is numbered together with other sins (2Tm 3,3) where it is written: "Slanderers, incontinent, unmerciful," etc. Therefore incontinence is a sin.
I answer that Incontinence about a matter may be considered in two ways. First it may be considered properly and simply: and thus incontinence is about concupiscences of pleasures of touch, even as intemperance is, as we have said in reference to continence (Question , Article ). In this way incontinence is a sin for two reasons: first, because the incontinent man goes astray from that which is in accord with reason; secondly, because he plunges into shameful pleasures. Hence the Philosopher says (Ethic. vii, 4) that "incontinence is censurable not only because it is wrong"---that is, by straying from reason---"but also because it is wicked"---that is, by following evil desires. Secondly, incontinence about a matter is considered, properly---inasmuch as it is a straying from reason---but not simply; for instance when a man does not observe the mode of reason in his desire for honor, riches, and so forth, which seem to be good in themselves. About such things there is incontinence, not simply but relatively, even as we have said above in reference to continence (Question , Article , ad 3). In this way incontinence is a sin, not from the fact that one gives way to wicked desires, but because one fails to observe the mode of reason even in the desire for things that are of themselves desirable.Thirdly, incontinence is said to be about a matter, not properly, but metaphorically. for instance about the desires for things of which one cannot make an evil use, such as the desire for virtue. A man may be said to be incontinent in these matters metaphorically, because just as the incontinent man is entirely led by his evil desire, even so is a man entirely led by his good desire which is in accord with reason. Such like incontinence is no sin, but pertains to the perfection of virtue.
Reply to Objection: 1. Man can avoid sin and do good, yet not without God's help, according to Jn 15,5: "Without Me you can do nothing." Wherefore the fact that man needs God's help in order to be continent, does not show incontinence to be no sin, for, as stated in Ethic. iii, 3, "what we can do by means of a friend we do, in a way, ourselves."
2. The judgment of reason is overcome in the incontinent man, not necessarily, for then he would commit no sin, but through a certain negligence on account of his not standing firm in resisting the passion by holding to the judgment formed by his reason.
3. This argument takes incontinence metaphorically and not properly.
Objection: 1. It would seem that the incontinent man sins more gravely than the intemperate. For, seemingly, the more a man acts against his conscience, the more gravely he sins, according to Lc 12,47, "That servant who knew the will of his lord . . . and did not . . . shall be beaten with many stripes." Now the incontinent man would seem to act against his conscience more than the intemperate because, according to Ethic. vii, 3, the incontinent man, though knowing how wicked are the things he desires, nevertheless acts through passion, whereas the intemperate man judges what he desires to be good. Therefore the incontinent man sins more gravely than the intemperate.
2. Further, apparently, the graver a sin is, the more incurable it is: wherefore the sins against the Holy Ghost, being most grave, are declared to be unpardonable. Now the sin of incontinence would appear to be more incurable than the sin of intemperance. For a person's sin is cured by admonishment and correction, which seemingly are no good to the incontinent man, since he knows he is doing wrong, and does wrong notwithstanding: whereas it seems to the intemperate man that he is doing well, so that it were good for him to be admonished. Therefore it would appear that the incontinent man sins more gravely than the intemperate.
3. Further, the more eagerly man sins, the more grievous his sin. Now the incontinent sins more eagerly than the intemperate, since the incontinent man has vehement passions and desires, which the intemperate man does not always have. Therefore the incontinent man sins more gravely than the intemperate.
On the contrary Impenitence aggravates every sin: wherefore Augustine says (De Verb. Dom. serm. xi, 12,13) that "impenitence is a sin against the Holy Ghost." Now according to the Philosopher (Ethic. vii, 8) "the intemperate man is not inclined to be penitent, for he holds on to his choice: but every incontinent man is inclined to repentance." Therefore the intemperate man sins more gravely than the incontinent.
I answer that According to Augustine [*De Duab. Anim. x, xi] sin is chiefly an act of the will, because "by the will we sin and live aright" [*Retract. i, 9]. Consequently where there is a greater inclination of the will to sin, there is a graver sin. Now in the intemperate man, the will is inclined to sin in virtue of its own choice, which proceeds from a habit acquired through custom: whereas in the incontinent man, the will is inclined to sin through a passion. And since passion soon passes, whereas a habit is "a disposition difficult to remove," the result is that the incontinent man repents at once, as soon as the passion has passed; but not so the intemperate man; in fact he rejoices in having sinned, because the sinful act has become connatural to him by reason of his habit. Wherefore in reference to such persons it is written (Pr 2,14) that "they are glad when they have done evil, and rejoice in most wicked things." Hence it follows that "the intemperate man is much worse than the incontinent," as also the Philosopher declares (Ethic. vii, 7).
Reply to Objection: 1. Ignorance in the intellect sometimes precedes the inclination of the appetite and causes it, and then the greater the ignorance, the more does it diminish or entirely excuse the sin, in so far as it renders it involuntary. On the other hand, ignorance in the reason sometimes follows the inclination of the appetite, and then such like ignorance, the greater it is, the graver the sin, because the inclination of the appetite is shown thereby to be greater. Now in both the incontinent and the intemperate man, ignorance arises from the appetite being inclined to something, either by passion, as in the incontinent, or by habit, as in the intemperate. Nevertheless greater ignorance results thus in the intemperate than in the incontinent. In one respect as regards duration, since in the incontinent man this ignorance lasts only while the passion endures, just as an attack of intermittent fever lasts as long as the humor is disturbed: whereas the ignorance of the intemperate man endures without ceasing, on account of the endurance of the habit, wherefore it is likened to phthisis or any chronic disease, as the Philosopher says (Ethic. vii, 8). In another respect the ignorance of the intemperate man is greater as regards the thing ignored. For the ignorance of the incontinent man regards some particular detail of choice (in so far as he deems that he must choose this particular thing now): whereas the intemperate man's ignorance is about the end itself, inasmuch as he judges this thing good, in order that he may follow his desires without being curbed. Hence the Philosopher says (Ethic. vii, 7,8) that "the incontinent man is better than the intemperate, because he retains the best principle [*(To beltiston, e arche), 'the best thing, i.e. the principle']," to wit, the right estimate of the end.
2. Mere knowledge does not suffice to cure the incontinent man, for he needs the inward assistance of grace which quenches concupiscence, besides the application of the external remedy of admonishment and correction, which induce him to begin to resist his desires, so that concupiscence is weakened, as stated above (Question , Article ). By these same means the intemperate man can be cured. But his curing is more difficult, for two reasons. The first is on the part of reason, which is corrupt as regards the estimate of the last end, which holds the same position as the principle in demonstrations. Now it is more difficult to bring back to the truth one who errs as to the principle; and it is the same in practical matters with one who errs in regard to the end. The other reason is on the part of the inclination of the appetite: for in the intemperate man this proceeds from a habit, which is difficult to remove, whereas the inclination of the incontinent man proceeds from a passion, which is more easily suppressed.
3. The eagerness of the will, which increases a sin, is greater in the intemperate man than in the incontinent, as explained above. But the eagerness of concupiscence in the sensitive appetite is sometimes greater in the incontinent man, because he does not sin except through vehement concupiscence, whereas the intemperate man sins even through slight concupiscence and sometimes forestalls it. Hence the Philosopher says (Ethic. vii, 7) that we blame more the intemperate man, "because he pursues pleasure without desiring it or with calm," i.e. slight desire. "For what would he have done if he had desired it with passion?"
Objection: 1. It would seem that the incontinent in anger is worse than the incontinent in desire. For the more difficult it is to resist the passion, the less grievous, apparently is incontinence: wherefore the Philosopher says (Ethic. vii, 7): "It is not wonderful, indeed it is pardonable if a person is overcome by strong and overwhelming pleasures or pains." Now, "as Heraclitus says, it is more difficult to resist desire than anger" [*Ethic. ii. 3]. Therefore incontinence of desire is less grievous than incontinence of anger.
2. Further, one is altogether excused from sin if the passion be so vehement as to deprive one of the judgment of reason, as in the case of one who becomes demented through passion. Now he that is incontinent in anger retains more of the judgment of reason, than one who is incontinent in desire: since "anger listens to reason somewhat, but desire does not" as the Philosopher states (Ethic. vii, 6). Therefore the incontinent in anger is worse than the incontinent in desire.
3. Further, the more dangerous a sin the more grievous it is. Now incontinence of anger would seem to be more dangerous, since it leads a man to a greater sin, namely murder, for this is a more grievous sin than adultery, to which incontinence of desire leads. Therefore incontinence of anger is graver than incontinence of desire.
On the contrary The Philosopher says (Ethic. vii, 6) that "incontinence of anger is less disgraceful than incontinence of desire."
I answer that The sin of incontinence may be considered in two ways. First, on the part of the passion which occasions the downfall of reason. In this way incontinence of desire is worse than incontinence of anger, because the movement of desire is more inordinate than the movement of anger. There are four reasons for this, and the Philosopher indicates them, Ethic. vii, 6: First, because the movement of anger partakes somewhat of reason, since the angry man tends to avenge the injury done to him, and reason dictates this in a certain degree. Yet he does not tend thereto perfectly, because he does not intend the due mode of vengeance. on the other hand, the movement of desire is altogether in accord with sense and nowise in accord with reason. Secondly, because the movement of anger results more from the bodily temperament owing to the quickness of the movement of the bile which tends to anger. Hence one who by bodily temperament is disposed to anger is more readily angry than one who is disposed to concupiscence is liable to be concupiscent: wherefore also it happens more often that the children of those who are disposed to anger are themselves disposed to anger, than that the children of those who are disposed to concupiscence are also disposed to concupiscence. Now that which results from the natural disposition of the body is deemed more deserving of pardon. Thirdly, because anger seeks to work openly, whereas concupiscence is fain to disguise itself and creeps in by stealth. Fourthly, because he who is subject to concupiscence works with pleasure, whereas the angry man works as though forced by a certain previous displeasure.Secondly, the sin of incontinence may be considered with regard to the evil into which one falls through forsaking reason; and thus incontinence of anger is, for the most part, more grievous, because it leads to things that are harmful to one's neighbor.
Objection: 1. It is more difficult to resist pleasure perseveringly than anger, because concupiscence is enduring. But for the moment it is more difficult to resist anger, on account of its impetuousness.
2. Concupiscence is stated to be without reason, not as though it destroyed altogether the judgment of reason, but because nowise does it follow the judgment of reason: and for this reason it is more disgraceful.
3. This argument considers incontinence with regard to its result.
We must next consider clemency and meekness, and the contrary vices. Concerning the virtues themselves there are four points of inquiry:
(1) Whether clemency and meekness are altogether identical?
(2) Whether each of them is a virtue?
(3) Whether each is a part of temperance?
(4) Of their comparison with the other virtues.
Objection: 1. It would seem that clemency and meekness are absolutely the same. For meekness moderates anger, according to the Philosopher (Ethic. iv, 5). Now anger is "desire of vengeance" [*Aristotle, Rhet. ii, 2]. Since, then, clemency "is leniency of a superior in inflicting punishment on an inferior," as Seneca states (De Clementia ii, 3), and vengeance is taken by means of punishment, it would seem that clemency and meekness are the same.
2. Further, Tully says (De Invent. Rhet. ii, 54) that "clemency is a virtue whereby the mind is restrained by kindness when unreasonably provoked to hatred of a person," so that apparently clemency moderates hatred. Now, according to Augustine [*Ep. ccxi], hatred is caused by anger; and this is the matter of meekness and clemency. Therefore seemingly clemency and meekness are absolutely the same.
3. Further, the same vice is not opposed to different virtues. But the same vice, namely cruelty, is opposed to meekness and clemency. Therefore it seems that meekness and clemency are absolutely the same.
On the contrary According to the aforesaid definition of Seneca (Objection  ) "clemency is leniency of a superior towards an inferior": whereas meekness is not merely of superior to inferior, but of each to everyone. Therefore meekness and clemency are not absolutely the same.
I answer that As stated in Ethic. ii, 3, a moral virtue is "about passions and actions." Now internal passions are principles of external actions, and are likewise obstacles thereto. Wherefore virtues that moderate passions, to a certain extent, concur towards the same effect as virtues that moderate actions, although they differ specifically. Thus it belongs properly to justice to restrain man from theft, whereunto he is inclined by immoderate love or desire of money, which is restrained by liberality; so that liberality concurs with justice towards the effect, which is abstention from theft. This applies to the case in point; because through the passion of anger a man is provoked to inflict a too severe punishment, while it belongs directly to clemency to mitigate punishment, and this might be prevented by excessive anger.Consequently meekness, in so far as it restrains the onslaught of anger, concurs with clemency towards the same effect; yet they differ from one another, inasmuch as clemency moderates external punishment, while meekness properly mitigates the passion of anger.
Reply to Objection: 1. Meekness regards properly the desire itself of vengeance; whereas clemency regards the punishment itself which is applied externally for the purpose of vengeance.
2. Man's affections incline to the moderation of things that are unpleasant to him in themselves. Now it results from one man loving another that he takes no pleasure in the latter's punishment in itself, but only as directed to something else, for instance justice, or the correction of the person punished. Hence love makes one quick to mitigate punishment ---and this pertains to clemency---while hatred is an obstacle to such mitigation. For this reason Tully says that "the mind provoked to hatred" that is to punish too severely, "is restrained by clemency," from inflicting too severe a punishment, so that clemency directly moderates not hatred but punishment.
3. The vice of anger, which denotes excess in the passion of anger, is properly opposed to meekness, which is directly concerned with the passion of anger; while cruelty denotes excess in punishing. Wherefore Seneca says (De Clementia ii, 4) that "those are called cruel who have reason for punishing, but lack moderation in punishing." Those who delight in a man's punishment for its own sake may be called savage or brutal, as though lacking the human feeling that leads one man to love another.
Objection: 1. It would seem that neither clemency nor meekness is a virtue. For no virtue is opposed to another virtue. Yet both of these are apparently opposed to severity, which is a virtue. Therefore neither clemency nor meekness is a virtue.
2. Further, "Virtue is destroyed by excess and defect" [*Ethic. ii, 2]. But both clemency and meekness consist in a certain decrease; for clemency decreases punishment, and meekness decreases anger. Therefore neither clemency nor meekness is a virtue.
3. Further, meekness or mildness is included (Mt 5,4) among the beatitudes, and (Ga 5,23) among the fruits. Now the virtues differ from the beatitudes and fruits. Therefore they are not comprised under virtue.
On the contrary Seneca says (De Clementia ii, 5): "Every good man is conspicuous for his clemency and meekness." Now it is virtue properly that belongs to a good man, since "virtue it is that makes its possessor good, and renders his works good also" (Ethic. ii, 6). Therefore clemency and meekness are virtues.
I answer that The nature of moral virtue consists in the subjection of appetite to reason, as the Philosopher declares (Ethic. i, 13). Now this is verified both in clemency and in meekness. For clemency, in mitigating punishment, "is guided by reason," according to Seneca (De Clementia ii, 5), and meekness, likewise, moderates anger according to right reason, as stated in Ethic. iv, 5. Wherefore it is manifest that both clemency and meekness are virtues.
Reply to Objection: 1. Meekness is not directly opposed to severity; for meekness is about anger. On the other hand, severity regards the external infliction of punishment, so that accordingly it would seem rather to be opposed to clemency, which also regards external punishing, as stated above (Article ). Yet they are not really opposed to one another, since they are both according to right reason. For severity is inflexible in the infliction of punishment when right reason requires it; while clemency mitigates punishment also according to right reason, when and where this is requisite. Wherefore they are not opposed to one another as they are not about the same thing.
2. According to the Philosopher (Ethic. iv, 5), "the habit that observes the mean in anger is unnamed; so that the virtue is denominated from the diminution of anger, and is designated by the name of meekness." For the virtue is more akin to diminution than to excess, because it is more natural to man to desire vengeance for injuries done to him, than to be lacking in that desire, since "scarcely anyone belittles an injury done to himself," as Sallust observes [*Cf. Question ]. As to clemency, it mitigates punishment, not in respect of that which is according to right reason, but as regards that which is according to common law, which is the object of legal justice: yet on account of some particular consideration, it mitigates the punishment, deciding, as it were, that a man is not to be punished any further. Hence Seneca says (De Clementia ii, 1): "Clemency grants this, in the first place, that those whom she sets free are declared immune from all further punishment; and remission of punishment due amounts to a pardon." Wherefore it is clear that clemency is related to severity as equity [the Greek 'epieikeia' [*Cf. Question ]] to legal justice, whereof severity is a part, as regards the infliction of punishment in accordance with the law. Yet clemency differs from equity, as we shall state further on (Article , ad 1).
3. The beatitudes are acts of virtue: while the fruits are delights in virtuous acts. Wherefore nothing hinders meekness being reckoned both virtue, and beatitude and fruit.
Objection: 1. It would seem that the aforesaid virtues are not parts of temperance. For clemency mitigates punishment, as stated above (Article ). But the Philosopher (Ethic. v, 10) ascribes this to equity, which pertains to justice, as stated above (Question , Article ). Therefore seemingly clemency is not a part of temperance.
2. Further, temperance is concerned with concupiscences; whereas meekness and clemency regard, not concupiscences, but anger and vengeance. Therefore they should not be reckoned parts of temperance.
3. Further, Seneca says (De Clementia ii, 4): "A man may be said to be of unsound mind when he takes pleasure in cruelty." Now this is opposed to clemency and meekness. Since then an unsound mind is opposed to prudence, it seems that clemency and meekness are parts of prudence rather than of temperance.
On the contrary Seneca says (De Clementia ii, 3) that "clemency is temperance of the soul in exercising the power of taking revenge." Tully also (De Invent. Rhet. ii, 54) reckons clemency a part of temperance.
I answer that Parts are assigned to the principal virtues, in so far as they imitate them in some secondary matter as to the mode whence the virtue derives its praise and likewise its name. Thus the mode and name of justice consist in a certain "equality," those of fortitude in a certain "strength of mind," those of temperance in a certain "restraint," inasmuch as it restrains the most vehement concupiscences of the pleasures of touch. Now clemency and meekness likewise consist in a certain restraint, since clemency mitigates punishment, while meekness represses anger, as stated above (Articles ,2). Therefore both clemency and meekness are annexed to temperance as principal virtue, and accordingly are reckoned to be parts thereof.
Reply to Objection: 1. Two points must be considered in the mitigation of punishment. one is that punishment should be mitigated in accordance with the lawgiver's intention, although not according to the letter of the law; and in this respect it pertains to equity. The other point is a certain moderation of a man's inward disposition, so that he does not exercise his power of inflicting punishment. This belongs properly to clemency, wherefore Seneca says (De Clementia ii, 3) that "it is temperance of the soul in exercising the power of taking revenge." This moderation of soul comes from a certain sweetness of disposition, whereby a man recoils from anything that may be painful to another. Wherefore Seneca says (De Clementia ii, 3) that "clemency is a certain smoothness of the soul"; for, on the other hand, there would seem to be a certain roughness of soul in one who fears not to pain others.
2. The annexation of secondary to principal virtues depends on the mode of virtue, which is, so to speak, a kind of form of the virtue, rather than on the matter. Now meekness and clemency agree with temperance in mode, as stated above, though they agree not in matter.
3. "Unsoundness" is corruption of "soundness." Now just as soundness of body is corrupted by the body lapsing from the condition due to the human species, so unsoundness of mind is due to the mind lapsing from the disposition due to the human species. This occurs both in respect of the reason, as when a man loses the use of reason, and in respect of the appetitive power, as when a man loses that humane feeling whereby "every man is naturally friendly towards all other men" (Ethic. viii, 1). The unsoundness of mind that excludes the use of reason is opposed to prudence. But that a man who takes pleasure in the punishment of others is said to be of unsound mind, is because he seems on this account to be devoid of the humane feeling which gives rise to clemency.
Objection: 1. It would seem that clemency and meekness are the greatest virtues. For virtue is deserving of praise chiefly because it directs man to happiness that consists in the knowledge of God. Now meekness above all directs man to the knowledge of God: for it is written (Jc 1,21): "With meekness receive the ingrafted word," and (Si 5,13): "Be meek to hear the word" of God. Again, Dionysius says (Ep. viii ad Demophil.) that "Moses was deemed worthy of the Divine apparition on account of his great meekness." Therefore meekness is the greatest of virtues.
2. Further, seemingly a virtue is all the greater according as it is more acceptable to God and men. Now meekness would appear to be most acceptable to God. For it is written (Si 1,34-35): "That which is agreeable" to God is "faith and meekness"; wherefore Christ expressly invites us to be meek like unto Himself (Mt 11,29), where He says: "Learn of Me, because I am meek and humble of heart"; and Hilary declares [*Comment. in Matth. iv, 3] that "Christ dwells in us by our meekness of soul." Again, it is most acceptable to men; wherefore it is written (Si 3,19): "My son, do thy works in meekness, and thou shalt be beloved above the glory of men": for which reason it is also declared (Pr 20,28) that the King's "throne is strengthened by clemency." Therefore meekness and clemency are the greatest of virtues.
3. Further, Augustine says (De Serm. Dom. in Monte i, 2) that "the meek are they who yield to reproaches, and resist not evil, but overcome evil by good." Now this seems to pertain to mercy or piety which would seem to be the greatest of virtues: because a gloss of Ambrose [*Hilary the deacon] on 1Tm 4,8, "Piety [Douay: 'Godliness'] is profitable to all things," observes that "piety is the sum total of the Christian religion." Therefore meekness and clemency are the greatest virtues.
On the contrary They are not reckoned as principal virtues, but are annexed to another, as to a principal, virtue.
I answer that Nothing prevents certain virtues from being greatest, not indeed simply, nor in every respect, but in a particular genus. It is impossible for clemency or meekness to be absolutely the greatest virtues, since they owe their praise to the fact that they withdraw a man from evil, by mitigating anger or punishment. Now it is more perfect to obtain good than to lack evil. Wherefore those virtues like faith, hope, charity, and likewise prudence and justice, which direct one to good simply, are absolutely greater virtues than clemency and meekness.Yet nothing prevents clemency and meekness from having a certain restricted excellence among the virtues which resist evil inclinations. For anger, which is mitigated by meekness, is, on account of its impetuousness, a very great obstacle to man's free judgment of truth: wherefore meekness above all makes a man self-possessed. Hence it is written (Si 10,31): "My son, keep thy soul in meekness." Yet the concupiscences of the pleasures of touch are more shameful, and harass more incessantly, for which reason temperance is more rightly reckoned as a principal virtue. as stated above (Question , Article , ad 2). As to clemency, inasmuch as it mitigates punishment, it would seem to approach nearest to charity, the greatest of the virtues, since thereby we do good towards our neighbor, and hinder his evil.
Reply to Objection: 1. Meekness disposes man to the knowledge of God, by removing an obstacle; and this in two ways. First, because it makes man self-possessed by mitigating his anger, as stated above; secondly, because it pertains to meekness that a man does not contradict the words of truth, which many do through being disturbed by anger. Wherefore Augustine says (De Doctr. Christ. ii, 7): "To be meek is not to contradict Holy Writ, whether we understand it, if it condemn our evil ways, or understand it not, as though we might know better and have a clearer insight of the truth."
2. Meekness and clemency make us acceptable to God and men, in so far as they concur with charity, the greatest of the virtues, towards the same effect, namely the mitigation of our neighbor's evils.
3. Mercy and piety agree indeed with meekness and clemency by concurring towards the same effect, namely the mitigation of our neighbor's evils. Nevertheless they differ as to motive. For piety relieves a neighbor's evil through reverence for a superior, for instance God or one's parents: mercy relieves a neighbor's evil, because this evil is displeasing to one, in so far as one looks upon it as affecting oneself, as stated above (Question , Article ): and this results from friendship which makes friends rejoice and grieve for the same things: meekness does this, by removing anger that urges to vengeance, and clemency does this through leniency of soul, in so far as it judges equitable that a person be no further punished.
We must next consider the contrary vices: (1) Anger that is opposed to meekness; (2) Cruelty that is opposed to clemency. Concerning anger there are eight points of inquiry:
(1) Whether it is lawful to be angry?
(2) Whether anger is a sin?
(3) Whether it is a mortal sin?
(4) Whether it is the most grievous of sins?
(5) Of its species;
(6) Whether anger is a capital vice?
(7) Of its daughters;
(8) Whether it has a contrary vice?
Objection: 1. It would seem that it cannot be lawful to be angry. For Jerome in his exposition on Mt 5,22, "Whosoever is angry with his brother," etc. says: "Some codices add 'without cause.' However, in the genuine codices the sentence is unqualified, and anger is forbidden altogether." Therefore it is nowise lawful to be angry.
2. Further, according to Dionysius (Div. Nom. iv) "The soul's evil is to be without reason." Now anger is always without reason: for the Philosopher says (Ethic. vii, 6) that "anger does not listen perfectly to reason"; and Gregory says (Moral. v, 45) that "when anger sunders the tranquil surface of the soul, it mangles and rends it by its riot"; and Cassian says (De Inst. Caenob. viii, 6): "From whatever cause it arises, the angry passion boils over and blinds the eye of the mind." Therefore it is always evil to be angry.
3. Further, anger is "desire for vengeance" [*Aristotle, Rhet. ii, 2] according to a gloss on Lv 19,17, "Thou shalt not hate thy brother in thy heart." Now it would seem unlawful to desire vengeance, since this should be left to God, according to Dt 32,35, "Revenge is Mine." Therefore it would seem that to be angry is always an evil.
4. Further, all that makes us depart from likeness to God is evil. Now anger always makes us depart from likeness to God, since God judges with tranquillity according to Sg 12,18. Therefore to be angry is always an evil.
On the contrary Chrysostom [*Hom. xi in the Opus Imperfectum, falsely ascribed to St. John Chrysostom] says: "He that is angry without cause, shall be in danger; but he that is angry with cause, shall not be in danger: for without anger, teaching will be useless, judgments unstable, crimes unchecked." Therefore to be angry is not always an evil.
I answer that Properly speaking anger is a passion of the sensitive appetite, and gives its name to the irascible power, as stated above (I-II 46,1) when we were treating of the passions. Now with regard to the passions of the soul, it is to be observed that evil may be found in them in two ways. First by reason of the passion's very species, which is derived from the passion's object. Thus envy, in respect of its species, denotes an evil, since it is displeasure at another's good, and such displeasure is in itself contrary to reason: wherefore, as the Philosopher remarks (Ethic. ii, 6), "the very mention of envy denotes something evil." Now this does not apply to anger, which is the desire for revenge, since revenge may be desired both well and ill. Secondly, evil is found in a passion in respect of the passion's quantity, that is in respect of its excess or deficiency; and thus evil may be found in anger, when, to wit, one is angry, more or less than right reason demands. But if one is angry in accordance with right reason, one's anger is deserving of praise.
Reply to Objection: 1. The Stoics designated anger and all the other passions as emotions opposed to the order of reason; and accordingly they deemed anger and all other passions to be evil, as stated above (I-II 24,2) when we were treating of the passions. It is in this sense that Jerome considers anger; for he speaks of the anger whereby one is angry with one's neighbor, with the intent of doing him a wrong.---But, according to the Peripatetics, to whose opinion Augustine inclines (De Civ. Dei ix, 4), anger and the other passions of the soul are movements of the sensitive appetite, whether they be moderated or not, according to reason: and in this sense anger is not always evil.
2. Anger may stand in a twofold relation to reason. First, antecedently; in this way it withdraws reason from its rectitude, and has therefore the character of evil. Secondly, consequently, inasmuch as the movement of the sensitive appetite is directed against vice and in accordance with reason, this anger is good, and is called "zealous anger." Wherefore Gregory says (Moral. v, 45): "We must beware lest, when we use anger as an instrument of virtue, it overrule the mind, and go before it as its mistress, instead of following in reason's train, ever ready, as its handmaid, to obey." This latter anger, although it hinder somewhat the judgment of reason in the execution of the act, does not destroy the rectitude of reason. Hence Gregory says (Moral. v, 45) that "zealous anger troubles the eye of reason, whereas sinful anger blinds it." Nor is it incompatible with virtue that the deliberation of reason be interrupted in the execution of what reason has deliberated: since art also would be hindered in its act, if it were to deliberate about what has to be done, while having to act.
3. It is unlawful to desire vengeance considered as evil to the man who is to be punished, but it is praiseworthy to desire vengeance as a corrective of vice and for the good of justice; and to this the sensitive appetite can tend, in so far as it is moved thereto by the reason: and when revenge is taken in accordance with the order of judgment, it is God's work, since he who has power to punish "is God's minister," as stated in Rm 13,4.
4. We can and ought to be like to God in the desire for good; but we cannot be altogether likened to Him in the mode of our desire, since in God there is no sensitive appetite, as in us, the movement of which has to obey reason. Wherefore Gregory says (Moral. v, 45) that "anger is more firmly erect in withstanding vice, when it bows to the command of reason."
