Q: Objection 1: It would seem that adultery is not a determinate species of lust, distinct from the other species. For adultery takes its name from a man having intercourse "with a woman who is not his own [ad alteram]," according to a gloss [*St. Augustine: Serm. li, 13 de Divers. lxiii] on Ex. 20:14. Now a woman who is not one's own may be of various conditions, namely either a virgin, or under her father's care, or a harlot, or of any other description. Therefore it seems that adultery is not a species of lust distinct from the others.

Obj. 2: Further, Jerome says [*Contra Jovin. i]: "It matters not for what reason a man behaves as one demented. Hence Sixtus the Pythagorean says in his Maxims: He that is insatiable of his wife is an adulterer," and in like manner one who is over enamored of any woman. Now every kind of lust includes a too ardent love. Therefore adultery is in every kind of lust: and consequently it should not be reckoned a species of lust.

Obj. 3: Further, where there is the same kind of deformity, there would seem to be the same species of sin. Now, apparently, there is the same kind of deformity in seduction and adultery: since in either case a woman is violated who is under another person's authority. Therefore adultery is not a determinate species of lust, distinct from the others.
Q: Objection 1: It would seem that incest is not a determinate species of lust. For incest [*
Incestus
is equivalent to in-castus = "unchaste"] takes its name from being a privation of chastity. But all kinds of lust are opposed to chastity. Therefore it seems that incest is not a species of lust, but is lust itself in general.

Obj. 2: Further, it is stated in the Decretals (XXXVI, qu. 1 [*Cf. Append. Grat. ad can. Lex illa]) that "incest is intercourse between a man and a woman related by consanguinity or affinity." Now affinity differs from consanguinity. Therefore it is not one but several species of lust.

Obj. 3: Further, that which does not, of itself, imply a deformity, does not constitute a determinate species of vice. But intercourse between those who are related by consanguinity or affinity does not, of itself, contain any deformity, else it would never have been lawful. Therefore incest is not a determinate species of lust.
Q: Whether Sacrilege Can Be a Species of Lust?

A: On the contrary,
Augustine says (De Civ. Dei xv, 16) that "if it is wicked, through covetousness, to go beyond one's earthly bounds, how much more wicked is it through venereal lust to transgress the bounds of morals!" Now to go beyond one's earthly bounds in sacred matters is a sin of sacrilege. Therefore it is likewise a sin of sacrilege to overthrow the bounds of morals through venereal desire in sacred matters. But venereal desire pertains to lust. Therefore sacrilege is a species of lust.

I answer that,
As stated above (I-II, Q. 18, AA. 6, 7), the act of a virtue or vice, that is directed to the end of another virtue or vice, assumes the latter's species: thus, theft committed for the sake of adultery, passes into the species of adultery. Now it is evident that as Augustine states (De Virgin. 8), the observance of chastity, by being directed to the worship of God, becomes an act of religion, as in the case of those who vow and keep chastity. Wherefore it is manifest that lust also, by violating something pertaining to the worship of God, belongs to the species of sacrilege: and in this way sacrilege may be accounted a species of lust.

Reply Obj. 1: Lust, by being directed to another vice as its end, becomes a species of that vice: and so a species of lust may be also a species of irreligion, as of a higher genus.

Reply Obj. 2: The enumeration referred to, includes those sins which are species of lust by their very nature: whereas sacrilege is a species of lust in so far as it is directed to another vice as its end, and may coincide with the various species of lust. For unlawful intercourse between persons mutually united by spiritual relationship, is a sacrilege after the manner of incest. Intercourse with a virgin consecrated to God, inasmuch as she is the spouse of Christ, is sacrilege resembling adultery. If the maiden be under her father's authority, it will be spiritual seduction; and if force be employed it will be spiritual rape, which kind of rape even the civil law punishes more severely than others. Thus the Emperor Justinian says [*Cod. i, iii de Episc. et Cler. 5]: "If any man dare, I will not say to rape, but even to tempt a consecrated virgin with a view to marriage, he shall be liable to capital punishment."

Reply Obj. 3: Sacrilege is committed on a consecrated thing. Now a consecrated thing is either a consecrated person, who is desired for sexual intercourse, and thus it is a kind of lust, or it is desired for possession, and thus it is a kind of injustice. Sacrilege may also come under the head of anger, for instance, if through anger an injury be done to a consecrated person. Again, one may commit a sacrilege by partaking gluttonously of sacred food. Nevertheless, sacrilege is ascribed more specially to lust which is opposed to chastity for the observance of which certain persons are specially consecrated.
Q: Objection 1: It would seem that sacrilege cannot be a species of lust. For the same species is not contained under different genera that are not subalternated to one another. Now sacrilege is a species of irreligion, as stated above (Q. 99, A. 2). Therefore sacrilege cannot be reckoned a species of lust.

Obj. 2: Further, the Decretals (XXXVI, qu. 1 [*Append. Grat. ad can. Lex illa]), do not place sacrilege among other sins which are reckoned species of lust. Therefore it would seem not to be a species of lust.

Obj. 3: Further, something derogatory to a sacred thing may be done by the other kinds of vice, as well as by lust. But sacrilege is not reckoned a species of gluttony, or of any other similar vice. Therefore neither should it be reckoned a species of lust.
Q: Whether the Unnatural Vice Is a Species of Lust?

A: On the contrary,
It is reckoned together with the other species of lust (2 Cor. 12:21) where we read: "And have not done penance for the uncleanness, and fornication, and lasciviousness," where a gloss says: "Lasciviousness, i.e., unnatural lust."

I answer that,
As stated above (AA. 6, 9) wherever there occurs a special kind of deformity whereby the venereal act is rendered unbecoming, there is a determinate species of lust. This may occur in two ways: First, through being contrary to right reason, and this is common to all lustful vices; secondly, because, in addition, it is contrary to the natural order of the venereal act as becoming to the human race: and this is called "the unnatural vice." This may happen in several ways. First, by procuring pollution, without any copulation, for the sake of venereal pleasure: this pertains to the sin of "uncleanness" which some call "effeminacy." Secondly, by copulation with a thing of undue species, and this is called "bestiality." Thirdly, by copulation with an undue sex, male with male, or female with female, as the Apostle states (Rom. 1:27): and this is called the "vice of sodomy." Fourthly, by not observing the natural manner of copulation, either as to undue means, or as to other monstrous and bestial manners of copulation.

Reply Obj. 1: There we enumerated the species of lust that are not contrary to human nature: wherefore the unnatural vice was omitted.

Reply Obj. 2: Bestiality differs from vice, for the latter is opposed to human virtue by a certain excess in the same matter as the virtue, and therefore is reducible to the same genus.

Reply Obj. 3: The lustful man intends not human generation but venereal pleasures. It is possible to have this without those acts from which human generation follows: and it is that which is sought in the unnatural vice.
Q: Objection 1: It would seem that the unnatural vice is not a species of lust. For no mention of the vice against nature is made in the enumeration given above (A. 1, Obj. 1). Therefore it is not a species of lust.

Obj. 2: Further, lust is contrary to virtue; and so it is comprised under vice. But the unnatural vice is comprised not under vice, but under bestiality, according to the Philosopher (Ethic. vii, 5). Therefore the unnatural vice is not a species of lust.

Obj. 3: Further, lust regards acts directed to human generation, as stated above (Q. 153, A. 2): Whereas the unnatural vice concerns acts from which generation cannot follow. Therefore the unnatural vice is not a species of lust.
Q: Objection 1: It would seem that the unnatural vice is not the greatest sin among the species of lust. For the more a sin is contrary to charity the graver it is. Now adultery, seduction and rape which are injurious to our neighbor are seemingly more contrary to the love of our neighbor, than unnatural sins, by which no other person is injured. Therefore the unnatural sin is not the greatest among the species of lust.

Obj. 2: Further, sins committed against God would seem to be the most grievous. Now sacrilege is committed directly against God, since it is injurious to the Divine worship. Therefore sacrilege is a graver sin than the unnatural vice.

Obj. 3: Further, seemingly, a sin is all the more grievous according as we owe a greater love to the person against whom that sin is committed. Now the order of charity requires that a man love more those persons who are united to him--and such are those whom he defiles by incest--than persons who are not connected with him, and whom in certain cases he defiles by the unnatural vice. Therefore incest is a graver sin than the unnatural vice.

Obj. 4: Further, if the unnatural vice is most grievous, the more it is against nature the graver it would seem to be. Now the sin of uncleanness or effeminacy would seem to be most contrary to nature, since it would seem especially in accord with nature that agent and patient should be distinct from one another. Hence it would follow that uncleanness is the gravest of unnatural vices. But this is not true. Therefore unnatural vices are not the most grievous among sins of lust.
Q: Whether Continence Is a Virtue?

A: On the contrary,
Every praiseworthy habit would seem to be a virtue. Now such is continence, for Andronicus says [*De Affectibus] that "continence is a habit unconquered by pleasure." Therefore continence is a virtue.

I answer that,
The word "continence" is taken by various people in two ways. For some understand continence to denote abstention from all venereal pleasure: thus the Apostle joins continence to chastity (Gal. 5:23). In this sense perfect continence is virginity in the first place, and widowhood in the second. Wherefore the same applies to continence understood thus, as to virginity which we have stated above (Q. 152, A. 3) to be a virtue. Others, however, understand continence as signifying that whereby a man resists evil desires, which in him are vehement. In this sense the Philosopher takes continence (Ethic. vii, 7), and thus also it is used in the Conferences of the Fathers (Collat. xii, 10, 11). In this way continence has something of the nature of a virtue, in so far, to wit, as the reason stands firm in opposition to the passions, lest it be led astray by them: yet it does not attain to the perfect nature of a moral virtue, by which even the sensitive appetite is subject to reason so that vehement passions contrary to reason do not arise in the sensitive appetite. Hence the Philosopher says (Ethic. iv, 9) that "continence is not a virtue but a mixture," inasmuch as it has something of virtue, and somewhat falls short of virtue.

If, however, we take virtue in a broad sense, for any principle of commendable actions, we may say that continence is a virtue.

Reply Obj. 1: The Philosopher includes continence in the same division with virtue in so far as the former falls short of virtue.

Reply Obj. 2: Properly speaking, man is that which is according to reason. Wherefore from the very fact that a man holds (
tenet se
) to that which is in accord with reason, he is said to contain himself. Now whatever pertains to perversion of reason is not according to reason. Hence he alone is truly said to be continent who stands to that which is in accord with right reason, and not to that which is in accord with perverse reason. Now evil desires are opposed to right reason, even as good desires are opposed to perverse reason. Wherefore he is properly and truly continent who holds to right reason, by abstaining from evil desires, and not he who holds to perverse reason, by abstaining from good desires: indeed, the latter should rather be said to be obstinate in evil.

Reply Obj. 3: The gloss quoted takes continence in the first sense, as denoting a perfect virtue, which refrains not merely from unlawful goods, but also from certain lawful things that are lesser goods, in order to give its whole attention to the more perfect goods.
Q: Objection 1: It would seem that continence is not a virtue. For species and genus are not co-ordinate members of the same division. But continence is co-ordinated with virtue, according to the Philosopher (Ethic. vii, 1, 9). Therefore continence is not a virtue.

Obj. 2: Further, no one sins by using a virtue, since, according to Augustine (De Lib. Arb. ii, 18, 19), "a virtue is a thing that no one makes ill use of." Yet one may sin by containing oneself: for instance, if one desire to do a good, and contain oneself from doing it. Therefore continence is not a virtue.

Obj. 3: Further, no virtue withdraws man from that which is lawful, but only from unlawful things: for a gloss on Gal. 5:23, "Faith, modesty," etc., says that by continence a man refrains even from things that are lawful. Therefore continence is not a virtue.
Q: Objection 1: It would seem that desires for pleasures of touch are not the matter of continence. For Ambrose says (De Offic. i, 46): "General decorum by its consistent form and the perfection of what is virtuous is restrained* in its every action." [*"Continentem" according to St. Thomas' reading; St. Ambrose wrote "concinentem = harmonious"].
Q: Whether the Subject of Continence Is the Concupiscible Power?

A: On the contrary,
Every virtue residing in a certain power removes the evil act of that power. But continence does not remove the evil act of the concupiscible: since "the continent man has evil desires," according to the Philosopher (Ethic. vii, 9). Therefore continence is not in the concupiscible power.

I answer that,
Every virtue while residing in a subject, makes that subject have a different disposition from that which it has while subjected to the opposite vice. Now the concupiscible has the same disposition in one who is continent and in one who is incontinent, since in both of them it breaks out into vehement evil desires. Wherefore it is manifest that continence is not in the concupiscible as its subject. Again the reason has the same disposition in both, since both the continent and the incontinent have right reason, and each of them, while undisturbed by passion, purposes not to follow his unlawful desires. Now the primary difference between them is to be found in their choice: since the continent man, though subject to vehement desires, chooses not to follow them, because of his reason; whereas the incontinent man chooses to follow them, although his reason forbids. Hence continence must needs reside in that power of the soul, whose act it is to choose; and that is the will, as stated above (I-II, Q. 13, A. 1).

Reply Obj. 1: Continence has for its matter the desires for pleasures of touch, not as moderating them (this belongs to temperance which is in the concupiscible), but its business with them is to resist them. For this reason it must be in another power, since resistance is of one thing against another.

Reply Obj. 2: The will stands between reason and the concupiscible, and may be moved by either. In the continent man it is moved by the reason, in the incontinent man it is moved by the concupiscible. Hence continence may be ascribed to the reason as to its first mover, and incontinence to the concupiscible power: though both belong immediately to the will as their proper subject.

Reply Obj. 3: Although the passions are not in the will as their subject, yet it is in the power of the will to resist them: thus it is that the will of the continent man resists desires.
Q: Objection 1: It would seem that the subject of continence is the concupiscible power. For the subject of a virtue should be proportionate to the virtue's matter. Now the matter of continence, as stated (A. 2), is desires for the pleasures of touch, which pertain to the concupiscible power. Therefore continence is in the concupiscible power.

Obj. 2: Further, "Opposites are referred to one same thing" [*Categ. viii]. But incontinence is in the concupiscible, whose passions overcome reason, for Andronicus says [*De Affectibus] that "incontinence is the evil inclination of the concupiscible, by following which it chooses wicked pleasures in disobedience to reason." Therefore continence is likewise in the concupiscible.

Obj. 3: Further, the subject of a human virtue is either the reason, or the appetitive power, which is divided into the will, the concupiscible and the irascible. Now continence is not in the reason, for then it would be an intellectual virtue; nor is it in the will, since continence is about the passions which are not in the will; nor again is it in the irascible, because it is not properly about the passions of the irascible, as stated above (A. 2, ad 2). Therefore it follows that it is in the concupiscible.
Q: Objection 1: It would seem that continence is better than temperance. For it is written (Ecclus. 26:20): "No price is worthy of a continent soul." Therefore no virtue can be equalled to continence.

Obj. 2: Further, the greater the reward a virtue merits, the greater the virtue. Now continence apparently merits the greater reward; for it is written (2 Tim. 2:5): "He . . . is not crowned, except he strive lawfully," and the continent man, since he is subject to vehement evil desires, strives more than the temperate man, in whom these things are not vehement. Therefore continence is a greater virtue than temperance.

Obj. 3: Further, the will is a more excellent power than the concupiscible. But continence is in the will, whereas temperance is in the concupiscible, as stated above (A. 3). Therefore continence is a greater virtue than temperance.
Q: Objection 1: It would seem that incontinence pertains not to the soul but to the body. For sexual diversity comes not from the soul but from the body. Now sexual diversity causes diversity of incontinence: for the Philosopher says (Ethic. vii, 5) that women are not described either as continent or as incontinent. Therefore incontinence pertains not to the soul but to the body.

Obj. 2: Further, that which pertains to the soul does not result from the temperament of the body. But incontinence results from the bodily temperament: for the Philosopher says (Ethic. vii, 7) that "it is especially people of a quick or choleric and atrabilious temper whose incontinence is one of unbridled desire." Therefore incontinence regards the body.

Obj. 3: Further, victory concerns the victor rather than the vanquished. Now a man is said to be incontinent, because "the flesh lusteth against the spirit," and overcomes it. Therefore incontinence pertains to the flesh rather than to the soul.
Q: Whether Incontinence Is a Sin?

A: On the contrary,
It is numbered together with other sins (2 Tim. 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 (Q. 155, A. 2). 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 (Q. 155, A. 2, 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 Obj. 1: Man can avoid sin and do good, yet not without God's help, according to John 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."

Reply Obj. 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.

Reply Obj. 3: This argument takes incontinence metaphorically and not properly.
Q: 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 Wis. 8:21, "I know [Vulg.: 'knew'] that I could not . . . be continent, except God gave it." Therefore incontinence is not a sin.

Obj. 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.

Obj. 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" (Gal. 2:20). Therefore incontinence is not a sin.
