The "Phaedrus" is a strangely flirtatious conversation between Socrates, the old man, and the beautiful youth Phaedrus. In it, Socrates shows that he can be quite an orator himself when he feels like it, then gets around to describing what we call "Platonic Love," a love which, while excited by the beautiful image of the earthly beloved, is actually a love for the transcendent. Plato is a genius and, as CS Lewis says, his Socrates is one of the few historical characters you feel like you've met once you read their disciple's description of them (his others are Jesus and Samuel Johnson. Good company).
