OF THE EFFECTS OF ANGER (FOUR ARTICLES)
We must now consider the effects of anger: under which head there are four points of inquiry:
(1) Whether anger causes pleasure?
(2) Whether above all it causes heat in the heart?
(3) Whether above all it hinders the use of reason?
(4) Whether it causes taciturnity?
Whether anger causes pleasure?
Objection 1: It would seem that anger does not cause pleasure. Because sorrow excludes pleasure. But anger is never without sorrow, since, as stated in Ethic. vii, 6, "everyone that acts from anger, acts with pain." Therefore anger does not cause pleasure.
Objection 2: Further, the Philosopher says (Ethic. iv, 5) that "vengeance makes anger to cease, because it substitutes pleasure for pain": whence we may gather that the angry man derives pleasure from vengeance, and that vengeance quells his anger. Therefore on the advent of pleasure, anger departs: and consequently anger is not an effect united with pleasure.
Objection 3: Further, no effect hinders its cause, since it is conformed to its cause. But pleasure hinders anger as stated in Rhet. ii, 3. Therefore pleasure is not an effect of anger.
On the contrary, The Philosopher (Ethic. iv, 5) quotes the saying that anger is "Sweet to the soul as honey to the taste" (Iliad, xviii, 109 [trl. Pope]).
I answer that, As the Philosopher says (Ethic. vii, 14), pleasures, chiefly sensible and bodily pleasures, are remedies against sorrow: and therefore the greater the sorrow or anxiety, the more sensible are we to the pleasure which heals it, as is evident in the case of thirst which increases the pleasure of drink. Now it is clear from what has been said (Q[47], AA[1],3), that the movement of anger arises from a wrong done that causes sorrow, for which sorrow vengeance is sought as a remedy. Consequently as soon as vengeance is present, pleasure ensues, and so much the greater according as the sorrow was greater. Therefore if vengeance be really present, perfect pleasure ensues, entirely excluding sorrow, so that the movement of anger ceases. But before vengeance is really present, it becomes present to the angry man in two ways: in one way, by hope; because none is angry except he hopes for vengeance, as stated above (Q[46], A[1]); in another way, by thinking of it continually, for to everyone that desires a thing it is pleasant to dwell on the thought of what he desires; wherefore the imaginings of dreams are pleasant. Accordingly an angry man takes pleasure in thinking much about vengeance. This pleasure, however, is not perfect, so as to banish sorrow and consequently anger.
Reply to Objection 1: The angry man does not grieve and rejoice at the same thing; he grieves for the wrong done, while he takes pleasure in the thought and hope of vengeance. Consequently sorrow is to anger as its beginning; while pleasure is the effect or terminus of anger.
Reply to Objection 2: This argument holds in regard to pleasure caused by the real presence of vengeance, which banishes anger altogether.
Reply to Objection 3: Pleasure that precedes hinders sorrow from ensuing, and consequently is a hindrance to anger. But pleasure felt in taking vengeance follows from anger.
Whether anger above all causes fervor in the heart?
Objection 1: It would seem that heat is not above all the effect of anger. For fervor, as stated above (Q[28], A[5]; Q[37], A[2]), belongs to love. But love, as above stated, is the beginning and cause of all the passions. Since then the cause is more powerful than its effect, it seems that anger is not the chief cause of fervor.
Objection 2: Further, those things which, of themselves, arouse fervor, increase as time goes on; thus love grows stronger the longer it lasts. But in course of time anger grows weaker; for the Philosopher says (Rhet. ii, 3) that "time puts an end to anger." Therefore fervor is not the proper effect of anger.
Objection 3: Further, fervor added to fervor produces greater fervor. But "the addition of a greater anger banishes already existing anger," as the Philosopher says (Rhet. ii, 3). Therefore anger does not cause fervor.
On the contrary, Damascene says (De Fide Orth. ii, 16) that "anger is fervor of the blood around the heart, resulting from an exhalation of the bile."
I answer that, As stated above (Q[44], A[1]), the bodily transmutation that occurs in the passions of the soul is proportionate to the movement of the appetite. Now it is evident that every appetite, even the natural appetite, tends with greater force to repel that which is contrary to it, if it be present: hence we see that hot water freezes harder, as though the cold acted with greater force on the hot object. Since then the appetitive movement of anger is caused by some injury inflicted, as by a contrary that is present; it follows that the appetite tends with great force to repel the injury by the desire of vengeance; and hence ensues great vehemence and impetuosity in the movement of anger. And because the movement of anger is not one of recoil, which corresponds to the action of cold, but one of prosecution, which corresponds to the action of heat, the result is that the movement of anger produces fervor of the blood and vital spirits around the heart, which is the instrument of the soul's passions. And hence it is that, on account of the heart being so disturbed by anger, those chiefly who are angry betray signs thereof in their outer members. For, as Gregory says (Moral. v, 30) "the heart that is inflamed with the stings of its own anger beats quick, the body trembles, the tongue stammers, the countenance takes fire, the eyes grow fierce, they that are well known are not recognized. With the mouth indeed he shapes a sound, but the understanding knows not what it says."
Reply to Objection 1: "Love itself is not felt so keenly as in the absence of the beloved," as Augustine observes (De Trin. x, 12). Consequently when a man suffers from a hurt done to the excellence that he loves, he feels his love thereof the more: the result being that his heart is moved with greater heat to remove the hindrance to the object of his love; so that anger increases the fervor of love and makes it to be felt more.
Nevertheless, the fervor arising from heat differs according as it is to be referred to love or to anger. Because the fervor of love has a certain sweetness and gentleness; for it tends to the good that one loves: whence it is likened to the warmth of the air and of the blood. For this reason sanguine temperaments are more inclined to love; and hence the saying that "love springs from the liver," because of the blood being formed there. On the other hand, the fervor of anger has a certain bitterness with a tendency to destroy, for it seeks to be avenged on the contrary evil: whence it is likened to the heat of fire and of the bile, and for this reason Damascene says (De Fide Orth. ii, 16) that it "results from an exhalation of the bile whence it takes its name ."
Reply to Objection 2: Time, of necessity, weakens all those things, the causes of which are impaired by time. Now it is evident that memory is weakened by time; for things which happened long ago easily slip from our memory. But anger is caused by the memory of a wrong done. Consequently the cause of anger is impaired little by little as time goes on, until at length it vanishes altogether. Moreover a wrong seems greater when it is first felt; and our estimate thereof is gradually lessened the further the sense of present wrong recedes into the past. The same applies to love, so long as the cause of love is in the memory alone; wherefore the Philosopher says (Ethic. viii, 5) that "if a friend's absence lasts long, it seems to make men forget their friendship." But in the presence of a friend, the cause of friendship is continually being multiplied by time: wherefore the friendship increases: and the same would apply to anger, were its cause continually multiplied.
Nevertheless the very fact that anger soon spends itself proves the strength of its fervor: for as a great fire is soon spent having burnt up all the fuel; so too anger, by reason of its vehemence, soon dies away.
