I concentrate on Epicurus' attempt to show that pleasure is complete, not just one aim we have for its own sake but ultimately the only non-instrumental aim we have. Epicurus tells us that we will be happy, have the best overall life, by having pleasure as our final aim, and that we shall achieve this by living according to the virtues, by becoming a certain kind of person.
