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:
A Whether every human action is good, or are there evil actions?
A Whether the good or evil of a human action is derived from its object?
A Whether it is derived from a circumstance?
A Whether it is derived from the end?
A Whether a human action is good or evil in its species?
A Whether an action has the species of good or evil from its end?
A Whether the species derived from the end is contained under the species derived from the object, as under its genus, or conversely?
A Whether any action is indifferent in its species?
A Whether an individual action can be indifferent?
A Whether a circumstance places a moral action in the species of good or evil?
A Whether every circumstance that makes an action better or worse, places the moral action in the species of good or evil?
