 The virtuous person rejoices in someone else’s performing a morally good act thanks to her knowledge of what virtue consists in. The pleasurable experience a musician gets from music is primarily a sensory one linked to her faculty of hearing, to be sure, but also derives, as in the case of morality, from her musical knowledge. In other words, having experience and knowledge of music, or any kind of art, allows one to be a good judge of music, or any kind of art —that is to say what we would call a person of “aesthetic” taste. The goal of building and transmitting such knowledge in order to help his readers to become good judges could be considered the main reason why Aristotle wrote about art.
