OF VICE AND SIN CONSIDERED IN THEMSELVES (SIX ARTICLES)
We have in the next place to consider vice and sin: about which six points have to be considered: (1) Vice and sin considered in themselves; (2) their distinction; (3) their comparison with one another; (4) the subject of sin; (5) the cause of sin; (6) the effect of sin.
Under the first head there are six points of inquiry:
(1) Whether vice is contrary to virtue?
(2) Whether vice is contrary to nature?
(3) Which is worse, a vice or a vicious act?
(4) Whether a vicious act is compatible with virtue?
(5) Whether every sin includes action?
(6) Of the definition of sin proposed by Augustine (Contra Faust. xxii): |Sin is a word, deed, or desire against the eternal law.|
