A late Socratic dialogue debating whether pleasure or intelligence is the good, ending with a ranked mixture of both under beauty, proportion, and truth.
Philebus stages a debate between Socrates and the young Protarchus, who defends the absent Philebus's claim that pleasure, enjoyment, and delight are the good for every living creature. Socrates counters that thinking, understanding, memory, and right opinion are closer to the good. Rather than settling the question by assertion, Socrates proposes they examine both pleasure and intelligence closely to see which is more akin to the good life, agreeing to award a 'second prize' to whichever comes closer if neither turns out to be the good itself.
The middle of the dialogue works through a series of technical distinctions: the difference between limited and unlimited things, the four-part scheme of limit, the unlimited, the mixture of the two, and the cause of the mixture; and a searching analysis of pleasure itself, including bodily pleasures, mixed pleasures of pain and pleasure together (as in scratching an itch, comedy, or anger), and the possibility of false pleasures that rest on false opinion, such as mistaking mere freedom from pain for pleasure. Socrates also sorts the sciences and arts by their degree of exactness, ranking mathematics and dialectic above crafts like music and medicine that rely on trained guesswork.
In the end neither pure pleasure nor pure intelligence wins outright. Socrates argues that a good life requires a mixture, and that what makes any mixture good is not pleasure or intellect as such but the presence of beauty, proportion, and truth within it. Intelligence is admitted to the mixture ahead of pleasure, and only the true and pure pleasures, along with those attending virtue, are let in; the most intense and long-remembered bodily pleasures are set last. The dialogue matters because it is Plato's most sustained technical treatment of pleasure's psychology and metaphysics, and because its final ranking (measure, proportion, and truth first; intellect second; the arts and true pleasures following; the purest pleasures last) is one of the few places Plato tries to grade goods rather than just name one supreme Form.
“Philebus, then, says that the good for every living creature is enjoyment, pleasure, delight, and whatever else belongs to that same family.”

It is a dialogue in which Socrates debates a young man named Protarchus, who defends Philebus's view that pleasure is the good for every living creature, against Socrates's claim that intelligence, thought, and right opinion are closer to it. The two work through the nature of pleasure, sorting genuine pleasures from false ones and pure from mixed pleasures, and the exactness of different sciences, before concluding that the good life is a mixture of both, but that beauty, proportion, and truth are what actually make any mixture good.
Neither wins outright. Socrates argues both pleasure and intelligence lack the self-sufficiency required to be the good by themselves. Instead the good life is a mixture: intellect is admitted first, and only true, pure pleasures and those that accompany virtue are let into the blend, while the most intense bodily pleasures rank last.
Socrates argues that some things people call pleasures are actually built on false opinion, for example mistaking mere absence of pain for pleasure, or misjudging a pleasure's size the way distant objects look smaller than they are. He compares the soul's memory to a scribe who can write either a true or a false account of what is felt, and pleasure can be false in the way that report is false.
He points to cases like scratching an itch, laughing at a friend's misfortune, or the pleasure people take in anger and lamentation, arguing that these blend pleasure and pain together rather than existing in pure form; comedy at a friend's expense, for instance, is analyzed as pleasure mixed with the pain of envy.
Socrates ranks dialectic and mathematics as the most exact sciences because they deal with what is constant and unchanging, while crafts like music, medicine, and navigation rely on trained guesswork and estimation built up through practice rather than precise measurement, placing them lower in exactness.
Socrates proposes an order with measure, proportion, and truth first as the cause of any good mixture; intellect and wisdom second; the arts, true opinions, and knowledge that follow intellect third; and pure, unmixed pleasures of the soul fourth, with the excessive bodily pleasures ranked last.
