If pleasure feels good, does that make it the best guide to a human life?
Plato’s Philebus opens in the middle of a quarrel. Philebus claims that enjoyment, pleasure and delight are the good for all living creatures. Socrates argues for intelligence: clear thought and knowledge. With Protarchus taking up the argument, the dialogue asks what deserves to steer a life—and whether either rival claim can stand on its own.
The question grows more demanding as Socrates examines what pleasure actually is. Are all pleasures alike? Can some be false? How does knowledge differ from opinion? The discussion moves from the familiar relief of drinking when thirsty to the puzzle of how one thing can also be many. Each turn asks you to look harder at an apparently simple answer.

“the safest general characterization of the European philosophical tradition is that it consists of a series of footnotes to Plato.”
In short
What would you choose: a life of endless pleasure with no mind at all, or a life of perfect thought with no feeling? In Philebus, Socrates puts that very choice to a young man named Protarchus, who finds neither life worth choosing.

Pleasure and wisdom meet as rival claimants
The dialogue opens in the middle of a quarrel. Philebus has claimed that enjoyment and delight are good for every living creature. Socrates answers that wisdom, understanding and memory are better. Philebus has handed the argument to Protarchus, a young man who now defends pleasure.
Socrates sets the terms with care. They are looking for a state of the soul that makes people happy. A third state might beat both claimants. If it does, the winner is whichever of the two sits closer to that third thing. This keeps the contest honest.

What is Plato's Philebus about?
Philebus asks what makes a human life good. Socrates and Protarchus weigh pleasure against wisdom, test each alone, and then rank the elements of a good mixed life, giving pleasure a lower place than mind.
Who are Socrates, Protarchus and Philebus in the dialogue?
Socrates leads the inquiry and defends wisdom. Philebus, who praises pleasure, goes silent early on. His young friend Protarchus takes over his side and answers Socrates for most of the dialogue.
What does the oyster life mean in Philebus?
Socrates imagines a life of great pleasure with no mind or memory. Such a creature could not know it was enjoying itself or recall past joy, so it lives like an oyster, not a human being.
