SOCRATES: I assume that there are two natures, one self-existent, and the other ever in want of something.

PROTARCHUS: What manner of natures are they?

SOCRATES: The one majestic ever, the other inferior.

PROTARCHUS: You speak riddles.

SOCRATES: You have seen loves good and fair, and also brave lovers of them.

PROTARCHUS: I should think so.

SOCRATES: Search the universe for two terms which are like these two and are present everywhere.

PROTARCHUS: Yet a third time I must say, Be a little plainer, Socrates.

SOCRATES: There is no difficulty, Protarchus; the argument is only in play, and insinuates that some things are for the sake of something else (relatives), and that other things are the ends to which the former class subserve (absolutes).

PROTARCHUS: Your many repetitions make me slow to understand.
