Whether intemperance is a childish sin?

Objections

Objection 1 : It would seem that intemperance is not a childish sin. For Jerome in commenting on Mt. 18:3, "Unless you be converted, and become as little children," says that "a child persists not in anger, is unmindful of injuries, takes no pleasure in seeing a beautiful woman," all of which is contrary to intemperance. Therefore intemperance is not a childish sin.
Objection 2 : Further, children have none but natural desires. Now "in respect of natural desires few sin by intemperance," according to the Philosopher (Ethic. iii, 11). Therefore intemperance is not a childish sin.
Objection 3 : Further, children should be fostered and nourished: whereas concupiscence and pleasure, about which intemperance is concerned, are always to be thwarted and uprooted, according to Col. 3:5, "Mortify . . . your members upon the earth, which are . . . concupiscence" [*Vulg.: 'your members which are upon the earth, fornication . . . concupiscence'], etc. Therefore intemperance is not a childish sin.
