We must now consider each single part of Penance, and (1) Contrition; (2) Confession; (3) Satisfaction. The consideration about Contrition will be fourfold: (1) What is it? (2) What should it be about? (3) How great should it be? (4) Of its duration; (5) Of its effect.

Under the first head there are three points of inquiry:

A[1] Whether Contrition is suitably defined?

A[2] Whether it is an act of virtue?

A[3] Whether attrition can become contrition?
