Title: St. Thomas and reflex principles
Post by: ptlopes on July 29, 2024, 05:09:54 PM
Hello,

Garrigou-Lagrange writes about conscience and probabilism in Reality (https://isidore.co/calibre/#panel=book_details&book_id=3033):

Quote from: Garrigou-LagrangeSt. Thomas, it is true, does cite at times other reflex principles, useful in forming conscience, for example, that in doubt we are to stand by the view which is presumably true. But if he seldom dwells on these reflex principles, it is because he holds that prudential certitude1039 is found in that view which is nearest to evident truth, and most in conformity, not with egoism, but with the inclination to virtue.

Where does St. Thomas teach the principle that "in doubt we are to stand by the view which is presumably true"?

Thanks.
God bless,
Pedro

Garrigou-Lagrange, O.P., cites Summa Theologica I-II q. 57 a. 5 ad 3 (https://isidore.co/aquinas/summa/FS/FS057.html#FSQ57A5THEP1:~:text=the%20truth%20of%20the%20practical%20intellect%20depends%20on%20conformity%20with%20right%20appetite), which contains the famous axiom:
Quote from: St. ThomasVerum [...] intellectus practici accipitur per conformitatem ad appetitum rectum.
[T]he truth of the practical intellect depends on conformity with right appetite.

Hello Geremia,

Isn't Garrigou-Lagrange talking about the reflex principle "when in doubt one must stand by presumption"?

"[T]he truth of the practical intellect depends on conformity with right appetite" isn't a reflex principle, if I'm not mistaken.

Best regards,
Pedro

That's true, but reflex principles follow from it / are an application of it.

How is the reflex principle we're talking about an application of the other principle? I never read about that. 

Thank you for tour answers.

It discusses reflex principles.
