Temperance (Sophrosyne in Greek) is the practice of moderation. It was one of the four “cardinal” virtues held to be vital to society in Hellenic culture. It is one of the Four Cardinal Virtues considered central to Christian behaviour by the Catholic Church and is an important tenet of the moral codes of other world religions—for example, it is one of the Five Precepts of Buddhism.

Classically, temperance was defined as governing natural appetites for the pleasure of senses according to the bounds of reason. No virtue could be sustained in the face of inability to control oneself, if the virtue was opposed to some desire; this is why it is classified as a cardinal virtue, where “cardinal” signifies “pivotal.”
