Whether purity belongs especially to chastity?

Objections

Objection 1 : It would seem that purity does not belong especially to chastity. For Augustine says (De Civ. Dei i, 18) that "purity is a virtue of the soul." Therefore it is not something belonging to chastity, but is of itself a virtue distinct from chastity.
Objection 2 : Further, "pudicitia" [purity] is derived from "pudor," which is equivalent to shame. Now shame, according to Damascene [*De Fide Orth. ii, 15], is about a disgraceful act, and this is common to all sinful acts. Therefore purity belongs no more to chastity than to the other virtues.
Objection 3 : Further, the Philosopher says (Ethic. iii, 12) that "every kind of intemperance is most deserving of reproach." Now it would seem to belong to purity to avoid all that is deserving of reproach. Therefore purity belongs to all the parts of temperance, and not especially to chastity.
