The word excellence is probably the fittest translation of the Greek arete, usually mistranslated virtue. The reader will avoid misunderstanding Plato and Aristotle if, where translators write virtue, he will substitute excellence, ability, or capacity. The Greek arete is the Roman virtus; both imply a masculine sort of excellence (Ares, god of war; vir, a male). Classical antiquity conceived virtue in terms of man, just as medieval Christianity conceived it in terms of woman.
