In the Euthyphro from Plato's Five Dialogues, Socrates argues with Euthyphro to the question "What is piety?" Euthyphro responded to Socrates several definitions of piety but none of the answers seem to satisfy Socrates. For each definition that Euthyphro gives to Socrates, Socrates would debate on it. One of Euthyphro attempt to the definition of piety is "what is dear to the gods is pious, what is not is impious" (7a, p.11). Although this definition was answered in the way that Socrates wanted it, Socrates still is not satisfied that the answer to this definition is true. This leads Euthyphro to state, "the pious is what all the gods love, and the opposite, what all the gods hate, is the impious" (9e, p. 14). In other words, because pious is loved by the gods it is being loved and is dear to the gods. Euthyphro who at this point is confident that he gave a fine statement is again being disagreed by Socrates. Socrates argues that the "god-beloved" is not the same as the pious nor the pious the same as the god-beloved. Socrates disputes and gives Euthyphro crucial evidence why pious is not identical to the "god-beloved."
             Socrates explains "if the god-beloved and the pious were the same, and the pious were loved because it was pious, then the god-beloved would be loved because it was god-beloved, and if the god-beloved would be loved because it was loved by the gods, then the pious would also be pious because it was loved by the gods" (11a, p. 16). These are opposite cases having different meanings from each other. One is of a kind to be loved because it is loved and the other is loved because it is of a kind to be loved. This contradicts with what Euthyphro and Socrates discussed earlier because "the pious is pious because it is loved by the gods" and "the god-beloved is loved because it is god-beloved" are not true statements; therefore...
