3. Body
a. Having shown in Art. 1 that virtue is a habit, he proposes to determine what sort of habit it is, by examining its four causes.
b. The elements of the definition include the four causes of virtue.
(1) Final cause: virtue orders its subject to good operation: "by which we live righteously" and "of which no one makes a bad use."
(2) Material cause: only powers in some way possessed of reason can be the subject of virtue: "the mind."
(3) Formal cause: virtue makes its subject good: "a good quality."
(4) Efficient cause: God is the cause of the infused virtues: "which God works in us without us."
Note: This definition applies to all virtue, except for the last phrase, which is applicable only to infused virtue.
