Reply Obj. 1: The human soul is the form of the body, and has certain powers which make use of bodily organs. The operations of these organs conduce somewhat to those operations of the soul which are accomplished without bodily instruments, namely to the acts of the intellect and of the will, in so far as the intellect receives from the senses, and the will is urged by passions of the sensitive appetite. Accordingly, since woman, as regards the body, has a weak temperament, the result is that for the most part, whatever she holds to, she holds to it weakly; although in rare cases the opposite occurs, according to Prov. 31:10, "Who shall find a valiant woman?" And since small and weak things "are accounted as though they were not" [*Aristotle, Phys. ii, 5] the Philosopher speaks of women as though they had not the firm judgment of reason, although the contrary happens in some women. Hence he states that "we do not describe women as being continent, because they are vacillating" through being unstable of reason, and "are easily led" so that they follow their passions readily.
Reply Obj. 2: It is owing to the impulse of passion that a man at once follows his passion before his reason counsels him. Now the impulse of passion may arise either from its quickness, as in bilious persons [*Cf. I-II, Q. 46, A. 5], or from its vehemence, as in the melancholic, who on account of their earthy temperament are most vehemently aroused. Even so, on the other hand, a man fails to stand to that which is counselled, because he holds to it in weakly fashion by reason of the softness of his temperament, as we have stated with regard to woman (ad 1). This is also the case with phlegmatic temperaments, for the same reason as in women. And these results are due to the fact that the bodily temperament is an occasional but not a sufficient cause of incontinence, as stated above.
Reply Obj. 3: In the incontinent man concupiscence of the flesh overcomes the spirit, not necessarily, but through a certain negligence of the spirit in not resisting strongly. _______________________
SECOND ARTICLE [II-II, Q. 156, Art. 2]
Whether Incontinence Is a Sin?
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.
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.
