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.

There are, then, three states of mind ... two vices--that of excess, and that of defect; and one virtue--the mean; and all these are in a certain sense opposed to one another; for the extremes are not only opposed to the mean, but also to one another; and the mean is opposed to the extremes.
But obviously a state which becomes progressively more and more of a unity will cease to be a state at all. Plurality of numbers is natural in a state; and the farther it moves away from plurality towards unity, the less of a state it becomes and the more a household, and the household in turn an individual.

And it makes no difference whether he is young in years or youthful in character.
