Those who merely possess the goods of fortune may be haughty and insolent;... they try to imitate the great-souled man without being really like him, and only copy him in what they can, reproducing his contempt for others but not his virtuous conduct. For the great-souled man is justified in despising other people - his estimates are correct; but most proud men have no good ground for their pride.
