Recommended translation: "Statesman" in The Being of the Beautiful: Plato's Theaetetus, Sophist, and Statesman,  trans. Seth Benardete (University of Chicago Press: 1984).

Excerpt:

Socrates
Really I am greatly indebted to you, Theodorus, for my acquaintance with Theaetetus and with the Stranger, too.

Theodorus
Presently, Socrates, you will be three times as much indebted, when they have worked out the statesman and the philosopher for you.

Socrates
Indeed! My dear Theodorus, can I believe my ears? Were those really the words of the great calculator and geometrician?

Theodorus
Why, what do you mean, Socrates?

Socrates
When you rated sophist, statesman, and philosopher at the same value, though they are farther apart in worth than your mathematical proportion can express.
