We must now consider equality among the virtues: under which head there are six points of inquiry:
(1) Whether one virtue can be greater or less than another?
(2) Whether all the virtues existing together in one subject are equal?
(3) Of moral virtue in comparison with intellectual virtue;
(4) Of the moral virtues as compared with one another;
(5) Of the intellectual virtues in comparison with one another;
(6) Of the theological virtues in comparison with one another. ________________________
FIRST ARTICLE [I-II, Q. 66, Art. 1]
Whether One Virtue Can Be Greater or Less Than Another?
Objection 1: It would seem that one virtue cannot be greater or less than another. For it is written (Apoc. 21:16) that the sides of the city of Jerusalem are equal; and a gloss says that the sides denote the virtues. Therefore all virtues are equal; and consequently one cannot be greater than another.
