Prudence
Practical wisdom: seeing what is truly good in a particular situation and choosing the right means to it.
Definitions from the tradition
Aristotle, Nicomachean Ethics VI.5: Practical wisdom (phronesis) is a true and reasoned state of capacity to act with regard to the things that are good or bad for man; it is concerned with particulars and is learned by experience.
Cicero, De Officiis I.15-19: The first part of the honorable is the perception and search for truth; Cicero warns against taking the unknown for the known and against spending effort on obscure and needless matters.
Aquinas, Summa Theologiae II-II, q. 47: Prudence is right reason applied to action. It belongs to counsel, judgment, and above all to command; it guides all the moral virtues by setting the mean for them.
Scripture, Proverbs 14:15 (KJV): “The simple believeth every word: but the prudent man looketh well to his going”
Scripture is quoted from the King James Version as given in the library’s text. Other definitions are summarized, not quoted.
