Pleasure causes us to do base actions and pain causes us to abstain from doing noble actions.
AristotleSo we must lay it down that the association which is a state exists not for the purpose of living together but for the sake of noble actions. Those who contribute most to this kind of association are for that very reason entitled to a larger share in the state than those who, though they may be equal or even superior in free birth and in family, are inferior in the virtue that belongs to a citizen. Similarly they are entitled to a larger share than those who are superior in riches but inferior in virtue.
AristotleWe do not act rightly because we have virtue or excellence. But they hesitate, waiting for the other fellow to make the first move-and he, in turn, waits for you.
