Whether incontinence is a sin?

Objections

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.
Objection 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.
Objection 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.
