Moral Theology: Its Method and Masters

The Positions Compared: Prudence and the Vices Against It

Drawn from the authors' own words; every quotation links to its place.

The virtues: Faith · Hope · Charity · Prudence · Justice · Fortitude · Temperance

Every point on which our authors part ways about prudence and the vices against it, as the comparison notes of the Virtues and Vices pages set them out, each set out here as its sides, with each author of this library who answers it placed on his side in his own words. St. Alphonsus has a column of his own: his Theologia moralis is not yet in this library, so his opinion is given as our authors report it, and where two of them report it differently, both reports are shown. The counts are of the authors in this library, whose shelf is not evenly balanced: it holds more Jesuits than any other school.

In the table, a letter is the side an author takes; ± means he sets out both without choosing; a blank means the fuller entry does not place him. Each point opens below, with every author quoted and linked.

One Word, Two Senses

Political prudence: the ruler's or the subject's

Our authors are evenly divided (A 1, B 1). The fuller entry.
