Prudence (Latin: prudentia, contracted from providentia meaning "seeing ahead, sagacity") is the ability to govern and discipline oneself by the use of reason. It is classically considered to be a virtue - in particular, one of the four cardinal virtues of Ancient Greek philosophy and one of the seven heavenly virtues of Christianity. Prudentia is an allegorical female personification of the virtue, whose attributes are a mirror and snake, and who is frequently depicted as a pair with Justitia, the Roman goddess of Justice.
The word derives from the 14th-century Old French word prudence, which, in turn, derives from the Latin prudentia meaning "foresight, sagacity". It is often associated with wisdom, insight, and knowledge. The virtue of prudence is the ability to judge between virtuous and vicious actions, not only in a general sense, but with regard to appropriate actions at a given time and place. Although prudence does not itself perform outward actions, and is concerned solely with internal discrimination and choice, all other virtues are regulated by it. For example, to distinguish the virtuous mean of courage from the vicious extremes of recklessness (excess) and cowardice (deficiency) is to be prudent.
