Summa Theologica I-II q. 94 a. 2 co.:
- Being
(principle of non-contradiction: "the same thing cannot be affirmed and denied at the same time") - The good
(principle of practical reason: "good is that which all things seek after.")- as "whatever is a means of preserving human life, and of warding off its obstacles"
- "according to that nature which he has in common with other animals", "such as sexual intercourse, education of offspring and so forth."
- "according to the nature of his reason", "to know the truth about God, and to live in society"; "for instance, to shun ignorance, to avoid offending those among whom one has to live, and other such things"
On Friss-Grisez's "conventional natural law theory" view, see:
