Question — Bontempi, Palladium Theologicum V · from Schola Thomistica

Question I: On truth

English · Latin · Both

1.

TRUTH is a special moral virtue seated in the will, whereby one loves to speak the truth in words and deeds. So D. Thom. art. 1. et 2. and S. Bonav. wills the same in explanatione terminorum Theologiae, near the end, thus defining: Truth is the virtue whereby the heart and words are commanded to accord with things. and 3. part. Centil. sect 44. thus defining: Truth is the virtue by which things that are, or were before, or are to be, are said unaltered. The same is had lib. 3. Compend. Theol. cap. 37.

2.

BUT this virtue does not consist in that consonance of the voice with the intellect, but in the expression consonant with it as commanded by the will. And although faith also, and the other intellectual virtues, are concerned with truth, yet those are concerned with truth to be sought and known; and this one with truth to be expressed. But this virtue has a mean, because it neither enlarges nor diminishes the thing to be signified. To it is opposed duplicity, which tends to one thing not in diverse, so as to intend one thing within and pretend another without.

IT IS, moreover, a potential part of Justice, as S. Bonavent. teaches in the places cited. D. Thom. art. 3. from Marcus Tullius l. 2. de invent. It agrees with Justice, because it is directed to another, expressing one's meaning, and because it preserves a certain equality, adapting signs to the things which the speaker manifests. But it falls short of the proper aspect of justice, because it does not contain a legal debt pertaining to justice, but rather arises from honesty, insofar as man owes it to another sincerely to express the truth; for since man is a sociable animal, he must preserve those things that are necessary for preserving society; such indeed is the sincere expression, especially in contracts; for men could not converse with one another unless they believed one another. Truth indeed also concerns those things that pertain to doctrine, but specially those that pertain to man, that man express himself such as he is. So D. Thom. art. 3. ad 3.
