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 what moves the will: and under this head there are six points of inquiry:

(1) Whether the will is moved by the intellect?

(2) Whether it is moved by the sensitive appetite?

(3) Whether the will moves itself?

(4) Whether it is moved by an extrinsic principle?

(5) Whether it is moved by a heavenly body?

(6) Whether the will is moved by God alone as by an extrinsic principle?
