Taking the form of a discussion between the hedonist Philebus, his naive disciple, Protarchus and Socrates, "Philebus" is a compelling consideration of the popular belief that pleasure is the greatest attainable good. Here, Socrates speculates on the differing intensities of both pleasure and pain; explores the notion that they can be divided into pure and impure types; considers the relationship between the one and the many; and establishes knowledge as a far higher goal. A profound argument that true fulfillment can only be achieved by the pursuit of beauty, truth and moderation, "Philebus" is among the earliest and most fascinating explorations of one of the most fundamental human questions: how to lead a good life.
