Euthyphro dilemma
The Euthyphro dilemma is found in Plato's dialogue Euthyphro, in which Socrates asks Euthyphro, "Is the pious (τὸ ὅσιον) loved by the gods because it is pious, or is it pious because it is loved by the gods? " (10a) Although it was originally applied to the ancient Greek pantheon, the dilemma has implications for modern monotheistic religions. Gottfried Leibniz asked whether the good and just "is good and just because God wills it or whether God wills it because it is good and just".
