Text: Summa Theologiae, Project Gutenberg #17897, First Part of the Second Part (Prima Secundae), translated by the Fathers of the English Dominican Province. The First Part of the Second Part of the Summa in the English Dominican translation (first printed 1911 to 1925; second and revised edition from 1920). A sample check on 2026-11-09 against pre-1931 printings at the Internet Archive (first printings of 1915 and 1916 and the second and revised edition of the 1920s) found that the article text matches, with no 1947 introduction, synopsis, or index.

We must now consider the subject of vice or sin: under which head there are ten points of inquiry:

(1) Whether the will can be the subject of sin?

(2) Whether the will alone is the subject of sin?

(3) Whether the sensuality can be the subject of sin?

(4) Whether it can be the subject of mortal sin?

(5) Whether the reason can be the subject of sin?

(6) Whether morose delectation or non-morose delectation be subjected in the higher reason?

(7) Whether the sin of consent in the act of sin is subjected in the higher reason?

(8) Whether the lower reason can be the subject of mortal sin?

(9) Whether the higher reason can be the subject of venial sin?

(10) Whether there can be in the higher reason a venial sin directed to its proper object?
