Summa Theologica by Saint Thomas Aquinas (best summer reads of all time .TXT) 📖

Obj. 3: Further, lust is caused by despair, according to Eph. 4:19, "Who despairing, have given themselves up to lasciviousness." But despair is not a capital vice; indeed, it is accounted a daughter of sloth, as stated above (Q. 35, A. 4, ad 2). Much less, therefore, is lust a capital vice.

On the contrary, Gregory (Moral. xxxi, 45) places lust among the capital vices.

I answer that, As stated above (Q. 148, A. 5; I-II, Q. 84, AA. 3, 4), a capital vice is one that has a very desirable end, so that through desire for that end, a man proceeds to commit many sins, all of which are said to arise from that vice as from a principal vice. Now the end of lust is venereal pleasure, which is very great. Wherefore this pleasure is very desirable as regards the sensitive appetite, both on account of the intensity of the pleasure, and because such like concupiscence is connatural to man. Therefore it is evident that lust is a capital vice.

Reply Obj. 1: As stated above (Q. 148, A. 6), according to some, the uncleanness which is reckoned a daughter of gluttony is a certain uncleanness of the body, and thus the objection is not to the point. If, however, it denote the uncleanness of lust, we must reply that it is caused by gluttony materially—in so far as gluttony provides the bodily matter of lust—and not under the aspect of final cause, in which respect chiefly the capital vices are said to be the cause of others.

Reply Obj. 2: As stated above (Q. 132, A. 4, ad 1), when we were treating of vainglory, pride is accounted the common mother of all sins, so that even the capital vices originate therefrom.

Reply Obj. 3: Certain persons refrain from lustful pleasures chiefly through hope of the glory to come, which hope is removed by despair, so that the latter is a cause of lust, as removing an obstacle thereto, not as its direct cause; whereas this is seemingly necessary for a capital vice. _______________________

FIFTH ARTICLE [II-II, Q. 153, Art. 5]

Whether the Daughters of Lust Are Fittingly Described?

Objection 1: It would seem that the daughters of lust are unfittingly reckoned to be "blindness of mind, thoughtlessness, inconstancy, rashness, self-love, hatred of God, love of this world and abhorrence or despair of a future world." For mental blindness, thoughtlessness and rashness pertain to imprudence, which is to be found in every sin, even as prudence is in every virtue. Therefore they should not be reckoned especially as daughters of lust.

Obj. 2: Further, constancy is reckoned a part of fortitude, as stated above (Q. 128, ad 6; Q. 137, A. 3). But lust is contrary, not to fortitude but to temperance. Therefore inconstancy is not a daughter of lust.

Obj. 3: Further, "Self-love extending to the contempt of God" is the origin of every sin, as Augustine says (De Civ. Dei xiv, 28). Therefore it should not be accounted a daughter of lust.

Obj. 4: Further, Isidore [*QQ. in Deut., qu. xvi] mentions four, namely, "obscene," "scurrilous," "wanton" and "foolish talking." There the aforesaid enumeration would seem to be superfluous.

On the contrary, stands the authority of Gregory (Moral. xxxi, 45).

I answer that, When the lower powers are strongly moved towards their objects, the result is that the higher powers are hindered and disordered in their acts. Now the effect of the vice of lust is that the lower appetite, namely the concupiscible, is most vehemently intent on its object, to wit, the object of pleasure, on account of the vehemence of the pleasure. Consequently the higher powers, namely the reason and the will, are most grievously disordered by lust.

Now the reason has four acts in matters of action. First there is simple understanding, which apprehends some end as good, and this act is hindered by lust, according to Dan. 13:56, "Beauty hath deceived thee, and lust hath perverted thy heart." In this respect we have "blindness of mind." The second act is counsel about what is to be done for the sake of the end: and this is also hindered by the concupiscence of lust. Hence Terence says (Eunuch., act 1, sc. 1), speaking of lecherous love: "This thing admits of neither counsel nor moderation, thou canst not control it by counseling." In this respect there is "rashness," which denotes absence of counsel, as stated above (Q. 53, A. 3). The third act is judgment about the things to be done, and this again is hindered by lust. For it is said of the lustful old men (Dan. 13:9): "They perverted their own mind . . . that they might not . . . remember just judgments." In this respect there is "thoughtlessness." The fourth act is the reason's command about the thing to be done, and this also is impeded by lust, in so far as through being carried away by concupiscence, a man is hindered from doing what his reason ordered to be done. [To this "inconstancy" must be referred.] [*The sentence in brackets is omitted in the Leonine edition.] Hence Terence says (Eunuch., act 1, sc. 1) of a man who declared that he would leave his mistress: "One little false tear will undo those words."

On the part of the will there results a twofold inordinate act. One is the desire for the end, to which we refer "self-love," which regards the pleasure which a man desires inordinately, while on the other hand there is "hatred of God," by reason of His forbidding the desired pleasure. The other act is the desire for the things directed to the end. With regard to this there is "love of this world," whose pleasures a man desires to enjoy, while on the other hand there is "despair of a future world," because through being held back by carnal pleasures he cares not to obtain spiritual pleasures, since they are distasteful to him.

Reply Obj. 1: According to the Philosopher (Ethic. vi, 5), intemperance is the chief corruptive of prudence: wherefore the vices opposed to prudence arise chiefly from lust, which is the principal species of intemperance.

Reply Obj. 2: The constancy which is a part of fortitude regards hardships and objects of fear; but constancy in refraining from pleasures pertains to continence which is a part of temperance, as stated above (Q. 143). Hence the inconstancy which is opposed thereto is to be reckoned a daughter of lust. Nevertheless even the first named inconstancy arises from lust, inasmuch as the latter enfeebles a man's heart and renders it effeminate, according to Osee 4:11, "Fornication and wine and drunkenness take away the heart [Douay: 'understanding']." Vegetius, too, says (De Re Milit. iii) that "the less a man knows of the pleasures of life, the less he fears death." Nor is there any need, as we have repeatedly stated, for the daughters of a capital vice to agree with it in matter (cf. Q. 35, A. 4, ad 2; Q. 118, A. 8, ad 1; Q. 148, A. 6).

Reply Obj. 3: Self-love in respect of any goods that a man desires for himself is the common origin of all sins; but in the special point of desiring carnal pleasures for oneself, it is reckoned a daughter of lust.

Reply Obj. 4: The sins mentioned by Isidore are inordinate external acts, pertaining in the main to speech; wherein there is a fourfold inordinateness. First, on account of the matter, and to this we refer "obscene words": for since "out of the abundance of the heart the mouth speaketh" (Matt. 12:34), the lustful man, whose heart is full of lewd concupiscences, readily breaks out into lewd words. Secondly, on account of the cause: for, since lust causes thoughtlessness and rashness, the result is that it makes a man speak without weighing or giving a thought to his words, which are described as "scurrilous." Thirdly, on account of the end: for since the lustful man seeks pleasure, he directs his speech thereto, and so gives utterance to "wanton words." Fourthly, on account of the sentiments expressed by his words, for through causing blindness of mind, lust perverts a man's sentiments, and so he gives way "to foolish talking," for instance, by expressing a preference for the pleasures he desires to anything else. _______________________

OF THE PARTS OF LUST
(In Twelve Articles)

We must now consider the parts of lust, under which head there are twelve points of inquiry:

(1) Into what parts is lust divided?

(2) Whether simple fornication is a mortal sin?

(3) Whether it is the greatest of sins?

(4) Whether there is mortal sin in touches, kisses and such like seduction?

(5) Whether nocturnal pollution is a mortal sin?

(6) Of seduction;

(7) Of rape;

(8) Of adultery;

(9) Of incest;

(10) Of sacrilege;

(11) Of the sin against nature;

(12) Of the order of gravity in the aforesaid sins. _______________________

FIRST ARTICLE [II-II, Q. 154, Art. 1]

Whether Six Species Are Fittingly Assigned to Lust?

Objection 1: It would seem that six species are unfittingly assigned to lust, namely, "simple fornication, adultery, incest, seduction, rape, and the unnatural vice." For diversity of matter does not diversify the species. Now the aforesaid division is made with regard to diversity of matter, according as the woman with whom a man has intercourse is married or a virgin, or of some other condition. Therefore it seems that the species of lust are diversified in this way.

Obj. 2: Further, seemingly the species of one vice are not differentiated by things that belong to another vice. Now adultery does not differ from simple fornication, save in the point of a man having intercourse with one who is another's, so that he commits an injustice. Therefore it seems that adultery should not be reckoned a species of lust.

Obj. 3: Further, just as a man may happen to have intercourse with a woman who is bound to another man by marriage, so may it happen that a man has intercourse with a woman who is bound to God by vow. Therefore sacrilege should be reckoned a species of lust, even as adultery is.

Obj. 4: Further, a married man sins not only if he be with another woman, but also if he use his own wife inordinately. But the latter sin is comprised under lust. Therefore it should be reckoned among the species thereof.

Obj. 5: Further, the Apostle says (2 Cor. 12:21): "Lest again, when I come, God humble me among you, and I mourn many of them that sinned before, and have not done penance for the uncleanness and fornication and lasciviousness that they have committed." Therefore it seems that also uncleanness and lasciviousness should be reckoned species of lust, as well as fornication.

Obj. 6: Further, the thing divided is not to be reckoned among its parts. But lust is reckoned together with the aforesaid: for it is written (Gal. 5:19): "The works of the flesh are manifest, which are fornication, uncleanness, immodesty, lust [Douay: 'luxury']." Therefore it seems that fornication is unfittingly reckoned a species of lust.

On the contrary, The aforesaid division is given in the Decretals 36, qu. i [*Append. Grat. ad can. Lex illa].

I answer that, As stated above (Q. 153, A. 3), the sin of lust consists in seeking venereal pleasure not in accordance with right reason. This may happen in two ways. First, in respect of the matter wherein this pleasure is sought; secondly, when, whereas there is due matter, other due circumstances are not observed. And since a circumstance, as such, does not specify a moral act, whose species is derived from its object which is also its matter, it follows that the species of lust must be assigned with respect to its matter or object.

Now this same matter may be discordant with right reason in two ways. First, because it is inconsistent with the end of the venereal act. In this way, as hindering the begetting of children, there is the vice against nature, which attaches to every venereal act from which generation cannot follow; and, as hindering the due upbringing and advancement of the child when born, there is simple fornication, which is the union of an unmarried man with an unmarried woman. Secondly, the matter wherein the venereal act is consummated may be discordant with right reason in relation to other persons; and this in two ways. First, with regard to the woman, with whom a man has connection, by reason of due honor not being paid to her; and thus there is incest, which consists in the misuse of a woman who is related by consanguinity or affinity. Secondly, with regard to the person under whose authority the woman is placed: and if she be under the authority of a husband, it is adultery, if under the authority of her father, it is seduction,
