Euthyphro
Euthyphro ( ; Ancient Greek: Εὐθύφρων, romanized: Euthyphrōn), is a philosophical work by Plato written in the form of a Socratic dialogue set during the weeks before the trial of Socrates in 399 BC. In the dialogue, Socrates and Euthyphro attempt to establish a definition of piety. This however leads to the main dilemma of the dialogue when the two cannot come to a satisfactory conclusion.
