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 Whether Contrition is suitably defined?
A Whether it is an act of virtue?
A Whether attrition can become contrition?
