STRANGER: It is clear, Theaetetus, that he who asserts the unity of being will find a difficulty in answering this or any other question.
THEAETETUS: Why so?
STRANGER: To admit of two names, and to affirm that there is nothing but unity, is surely ridiculous?
THEAETETUS: Certainly.
STRANGER: And equally irrational to admit that a name is anything?
THEAETETUS: How so?
STRANGER: To distinguish the name from the thing, implies duality.
THEAETETUS: Yes.
STRANGER: And yet he who identifies the name with the thing will be compelled to say that it is the name of nothing, or if he says that it is the name of something, even then the name will only be the name of a name, and of nothing else.
THEAETETUS: True.
