We must now consider fasting: under which head there are eight points of inquiry:
- Whether fasting is an act of virtue?
- Of what virtue is it the act?
- Whether it is a matter of precept?
- Whether anyone is excused from fulfilling this precept?
- The time of fasting;
- Whether it is requisite for fasting to eat but once?
- The hour of eating for those who fast;
- The meats from which it is necessary to abstain.
