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[1] Whether every human action is good, or are there evil actions?

A[2] Whether the good or evil of a human action is derived from its object?

A[3] Whether it is derived from a circumstance?

A[4] Whether it is derived from the end?

A[5] Whether a human action is good or evil in its species?

A[6] Whether an action has the species of good or evil from its end?

A[7] Whether the species derived from the end is contained under the species derived from the object, as under its genus, or conversely?

A[8] Whether any action is indifferent in its species?

A[9] Whether an individual action can be indifferent?

A[10] Whether a circumstance places a moral action in the species of good or evil?

A[11] Whether every circumstance that makes an action better or worse, places the moral action in the species of good or evil?
