MENO: I should like nothing better.
SOCRATES: Do not he and you and Empedocles say that there are certain effluences of existence?
MENO: Certainly.
SOCRATES: And passages into which and through which the effluences pass?
MENO: Exactly.
SOCRATES: And some of the effluences fit into the passages, and some of them are too small or too large?
MENO: True.
SOCRATES: And there is such a thing as sight?
MENO: Yes.
SOCRATES: And now, as Pindar says, 'read my meaning:'—colour is an effluence of form, commensurate with sight, and palpable to sense.
