Thomas Aquinas - Summa Theologica, Part I-II (Pars Prima Secundae)

Reply Obj. 3: The very fact that a man hates whatever is opposed to the object of his love, is the effect of love. Hence zeal is set down as an effect of love rather than of hatred. ________________________

FIFTH ARTICLE [I-II, Q. 28, Art. 5]

Whether Love Is a Passion That Wounds the Lover?

Objection 1: It would seem that love wounds the lover. For languor denotes a hurt in the one that languishes. But love causes languor: for it is written (Cant 2:5): "Stay me up with flowers, compass me about with apples; because I languish with love." Therefore love is a wounding passion.

Obj. 2: Further, melting is a kind of dissolution. But love melts that in which it is: for it is written (Cant 5:6): "My soul melted when my beloved spoke." Therefore love is a dissolvent: therefore it is a corruptive and a wounding passion.

Obj. 3: Further, fervor denotes a certain excess of heat; which excess has a corruptive effect. But love causes fervor: for Dionysius (Coel. Hier. vii) in reckoning the properties belonging to the Seraphim's love, includes "hot" and "piercing" and "most fervent." Moreover it is said of love (Cant 8:6) that "its lamps are fire and flames." Therefore love is a wounding and corruptive passion.

On the contrary, Dionysius says (Div. Nom. iv) that "everything loves itself with a love that holds it together," i.e. that preserves it. Therefore love is not a wounding passion, but rather one that preserves and perfects.

I answer that, As stated above (Q. 26, AA. 1, 2; Q. 27, A. 1), love denotes a certain adapting of the appetitive power to some good. Now nothing is hurt by being adapted to that which is suitable to it; rather, if possible, it is perfected and bettered. But if a thing be adapted to that which is not suitable to it, it is hurt and made worse thereby. Consequently love of a suitable good perfects and betters the lover; but love of a good which is unsuitable to the lover, wounds and worsens him. Wherefore man is perfected and bettered chiefly by the love of God: but is wounded and worsened by the love of sin, according to Osee 9:10: "They became abominable, as those things which they loved."

And let this be understood as applying to love in respect of its formal element, i.e. in regard to the appetite. But in respect of the material element in the passion of love, i.e. a certain bodily change, it happens that love is hurtful, by reason of this change being excessive: just as it happens in the senses, and in every act of a power of the soul that is exercised through the change of some bodily organ.

In reply to the objections, it is to be observed that four proximate effects may be ascribed to love: viz. melting, enjoyment, languor, and fervor. Of these the first is "melting," which is opposed to freezing. For things that are frozen, are closely bound together, so as to be hard to pierce. But it belongs to love that the appetite is fitted to receive the good which is loved, inasmuch as the object loved is in the lover, as stated above (A. 2). Consequently the freezing or hardening of the heart is a disposition incompatible with love: while melting denotes a softening of the heart, whereby the heart shows itself to be ready for the entrance of the beloved. If, then, the beloved is present and possessed, pleasure or enjoyment ensues. But if the beloved be absent, two passions arise; viz. sadness at its absence, which is denoted by "languor" (hence Cicero in De Tusc. Quaest. iii, 11 applies the term "ailment" chiefly to sadness); and an intense desire to possess the beloved, which is signified by "fervor." And these are the effects of love considered formally, according to the relation of the appetitive power to its object. But in the passion of love, other effects ensue, proportionate to the above, in respect of a change in the organ. ________________________

SIXTH ARTICLE [I-II, Q. 28, Art. 6]

Whether Love Is Cause of All That the Lover Does?

Objection 1: It would seem that the lover does not do everything from love. For love is a passion, as stated above (Q. 26, A. 2). But man does not do everything from passion: but some things he does from choice, and some things from ignorance, as stated in Ethic. v, 8. Therefore not everything that a man does, is done from love.

Obj. 2: Further, the appetite is a principle of movement and action in all animals, as stated in De Anima iii, 10. If, therefore, whatever a man does is done from love, the other passions of the appetitive faculty are superfluous.

Obj. 3: Further, nothing is produced at one and the same time by contrary causes. But some things are done from hatred. Therefore all things are not done from love.

On the contrary, Dionysius says (Div. Nom. iv) that "all things, whatever they do, they do for the love of good."

I answer that, Every agent acts for an end, as stated above (Q. 1, A. 2). Now the end is the good desired and loved by each one. Wherefore it is evident that every agent, whatever it be, does every action from love of some kind.

Reply Obj. 1: This objection takes love as a passion existing in the sensitive appetite. But here we are speaking of love in a general sense, inasmuch as it includes intellectual, rational, animal, and natural love: for it is in this sense that Dionysius speaks of love in chapter iv of De Divinis Nominibus.

Reply Obj. 2: As stated above (A. 5; Q. 27, A. 4) desire, sadness and pleasure, and consequently all the other passions of the soul, result from love. Wherefore every act that proceeds from any passion, proceeds also from love as from a first cause: and so the other passions, which are proximate causes, are not superfluous.

Reply Obj. 3: Hatred also is a result of love, as we shall state further on (Q. 29, A. 2).

We must now consider hatred: concerning which there are six points of inquiry:

(1) Whether evil is the cause and the object of hatred?

(2) Whether love is the cause of hatred?

(3) Whether hatred is stronger than love?

(4) Whether a man can hate himself?

(5) Whether a man can hate the truth?

(6) Whether a thing can be the object of universal hatred? ________________________

FIRST ARTICLE [I-II, Q. 29, Art. 1]

Whether Evil Is the Cause and Object of Hatred?

Objection 1: It would seem that evil is not the object and cause of hatred. For everything that exists, as such, is good. If therefore evil be the object of hatred, it follows that nothing but the lack of something can be the object of hatred: which is clearly untrue.

Obj. 2: Further, hatred of evil is praiseworthy; hence (2 Macc. 3:1) some are praised for that "the laws were very well kept, because of the godliness of Onias the high-priest, and the hatred of their souls [Douay: 'his soul'] had no evil." If, therefore, nothing but evil be the object of hatred, it would follow that all hatred is commendable: and this is clearly false.

Obj. 3: Further, the same thing is not at the same time both good and evil. But the same thing is lovable and hateful to different subjects. Therefore hatred is not only of evil, but also of good.

On the contrary, Hatred is the opposite of love. But the object of love is good, as stated above (Q. 26, A. 1; Q. 27, A. 1). Therefore the object of hatred is evil.

I answer that, Since the natural appetite is the result of apprehension (though this apprehension is not in the same subject as the natural appetite), it seems that what applies to the inclination of the natural appetite, applies also to the animal appetite, which does result from an apprehension in the same subject, as stated above (Q. 26, A. 1). Now, with regard to the natural appetite, it is evident, that just as each thing is naturally attuned and adapted to that which is suitable to it, wherein consists natural love; so has it a natural dissonance from that which opposes and destroys it; and this is natural hatred. So, therefore, in the animal appetite, or in the intellectual appetite, love is a certain harmony of the appetite with that which is apprehended as suitable; while hatred is dissonance of the appetite from that which is apprehended as repugnant and hurtful. Now, just as whatever is suitable, as such, bears the aspect of good; so whatever is repugnant, as such, bears the aspect of evil. And therefore, just as good is the object of love, so evil is the object of hatred.
