"Socrates: But if the god-loved and the pious were the same, my dear Euthyphro, then if the pious was being loved because it was pious, the god-loved would also be being loved because it was god-loved; and if the god-loved was god-loved because it was being loved by the gods, then the pious would also be pious because it was being loved by the gods. But now you see that they are in opposite cases as being altogether different from each other: the one is such as to be loved because it is being loved, the other is being loved because it is such as to be loved. I’m afraid, Euthyphro, that when you were asked what piety is, you did not wish to make its nature clear to me, but you told me an affect or quality of it, that the pious has the quality of being loved by all the gods, but you have not yet told me what the pious is. Now, if you will, do not hide things from me but tell me again from the beginning what piety is, whether being loved by the gods or having some other quality—we shall not quarrel about that—but be keen to tell me what the pious and the impious are."
