Thomas Aquinas, Summa Theologiae, First Part. 10 articles.

Read in the reading room → This question at New Advent

Text: Summa Theologiae, Project Gutenberg #17611, First Part (Prima Pars), translated by the Fathers of the English Dominican Province. The First 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. The phrase “From the Complete American Edition” in Gutenberg's catalog title is a provenance note only. Question and article numbers were added by the transcriber. Rights: Public domain (US)

To place our purpose within proper limits, we first endeavor to investigate the nature and extent of this sacred doctrine. Concerning this there are ten points of inquiry:

(1) Whether it is necessary?

(2) Whether it is a science?

(3) Whether it is one or many?

(4) Whether it is speculative or practical?

(5) How it is compared with other sciences?

(6) Whether it is the same as wisdom?

(7) Whether God is its subject-matter?

(8) Whether it is a matter of argument?

(9) Whether it rightly employs metaphors and similes?

(10) Whether the Sacred Scripture of this doctrine may be expounded in different senses?
