THEAETETUS: By all means.

STRANGER: Then let them answer this question: One, you say, alone is?

'Yes,' they will reply.

THEAETETUS: True.

STRANGER: And there is something which you call 'being'?

THEAETETUS: 'Yes.'

STRANGER: And is being the same as one, and do you apply two names to

the same thing?

THEAETETUS: What will be their answer, Stranger?

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.
