evidence: Excellence, for him, is concerned with passions and actions and the character of the agent is to be revealed by the voluntary choices she makes. Human choice aims at the good, or at the perceived good, and the ability to make excellent choices requires accurate knowledge of a particular situation, good reasoning skills, and a well-developed virtuous character. Becoming a virtuous person depends upon one’s habituation and practice of the various virtues. Thus, if you want to become temperate then practice of self-moderation and if you want to become courageous then practice actions that challenge your fears. "Excellence is an art won by training and habituation. We do not act rightly because we have virtue or excellence, but we rather have those because we have acted rightly. Excellence, then, is not an act but a habit" (Nicomachean Ethics, Bk. 2). [...] By acting ethically we express our excellence as rational creatures.
