QUESTION 18
OF THE GOOD AND EVIL OF HUMAN ACTS, IN GENERAL (In Eleven Articles)
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?
