Aristotle claimed that the happiest life for a human being is the life of moral virtue. The life of courage, temperance, justice, and the other virtues of character is better for the person living that life than a life that lacks those virtues. Having the sort of character which leads in a predictable way to actions which are, on the whole, socially beneficial ones, is in the best interest of any individual.
