Abstract
Socrates: Euthyphro, you think that you have such accurate knowledge of things divine, and what is holy and unholy, that... you can accuse your father? You are not afraid that you yourself are doing an unholy deed?
Euthyphro: Why Socrates, if I did not have an accurate knowledge of all that, I should be good for nothing, and Euthyphro would be no different from the general run of men.
(Euthyphro, 4e-5a)
