Philebus

The Philebus, is one of the surviving Socratic dialogues written in the 4th century BC by the ancient Greek philosopher Plato. Apart from Socrates, the primary speaker in Philebus, the other speakers are Philebus and Protarchus. But Philebus, who wants to defend the life of pleasure, hedonism, which Socrates describes as the life of an oyster, hardly participates, and his position has to be defended by Protarchus, who has learnt argumentation from Sophists.
