FIRST ARTICLE [II-II, Q. 156, Art. 1]
Whether Incontinence Pertains to the Soul or to the Body?
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.
On the contrary, Man differs from beast chiefly as regards the soul. Now they differ in respect of continence and incontinence, for we ascribe neither continence nor incontinence to the beasts, as the Philosopher states (Ethic. vii, 3). Therefore incontinence is chiefly on the part of the soul.
I answer that, Things are ascribed to their direct causes rather than to those which merely occasion them. Now that which is on the part of the body is merely an occasional cause of incontinence; since it is owing to a bodily disposition that vehement passions can arise in the sensitive appetite which is a power of the organic body. Yet these passions, however vehement they be, are not the sufficient cause of incontinence, but are merely the occasion thereof, since, so long as the use of reason remains, man is always able to resist his passions. If, however, the passions gain such strength as to take away the use of reason altogether—as in the case of those who become insane through the vehemence of their passions—the essential conditions of continence or incontinence cease, because such people do not retain the judgment of reason, which the continent man follows and the incontinent forsakes. From this it follows that the direct cause of incontinence is on the part of the soul, which fails to resist a passion by the reason. This happens in two ways, according to the Philosopher (Ethic. vii, 7): first, when the soul yields to the passions, before the reason has given its counsel; and this is called "unbridled incontinence" or "impetuosity": secondly, when a man does not stand to what has been counselled, through holding weakly to reason's judgment; wherefore this kind of incontinence is called "weakness." Hence it is manifest that incontinence pertains chiefly to the soul.
