Book VIII · 39
In the constitution of the rational animal I see no virtue which is opposed to justice; but I see a virtue which is opposed to love of pleasure, and that is temperance.
In the constitution of rational creatures I see no virtue incompatible with justice, but incompatible with pleasure I see—continence.
Marcus Aurelius, Meditations VIII.39. Translated by George Long (1862). The Stoic Library.
