We must now consider the good and evil of human acts. First, how a human act is good or evil; secondly, what results from the good or evil of a human act, as merit or demerit, sin and guilt.
Under the first head there will be a threefold consideration: the first will be of the good and evil of human acts, in general; the second, of the good and evil of internal acts; the third, of the good and evil of external acts.
Concerning the first there are eleven points of inquiry:
(1) Whether every human action is good, or are there evil actions?
(2) Whether the good or evil of a human action is derived from its object?
(3) Whether it is derived from a circumstance?
(4) Whether it is derived from the end?
(5) Whether a human action is good or evil in its species?
(6) Whether an action has the species of good or evil from its end?
(7) Whether the species derived from the end is contained under the species derived from the object, as under its genus, or conversely?
(8) Whether any action is indifferent in its species?
(9) Whether an individual action can be indifferent?
(10) Whether a circumstance places a moral action in the species of good or evil?
(11) Whether every circumstance that makes an action better or worse, places the moral action in the species of good or evil?
