SOCRATES: As the argument proceeds, my boy, I dare say that the meaning will become clearer.

PROTARCHUS: Very likely.

SOCRATES: Here are two new principles.

PROTARCHUS: What are they?

SOCRATES: One is the generation of all things, and the other is essence.

PROTARCHUS: I readily accept from you both generation and essence.

SOCRATES: Very right; and would you say that generation is for the sake of essence, or essence for the sake of generation?

PROTARCHUS: You want to know whether that which is called essence is, properly speaking, for the sake of generation?

SOCRATES: Yes.

PROTARCHUS: By the gods, I wish that you would repeat your question.
