Plato 
Euthyphro 

In the Meno, Anytus had parted from Socrates with the significant words: ‚That in any city, and particularly in the city of Athens, it is easier to do men harm than to do them good;‘ and Socrates was anticipating another opportunity of talking with him. In the Euthyphro, Socrates is awaiting his trial for impiety. But before the trial begins, Plato would like to put the world on their trial, and convince them of ignorance in that very matter touching which Socrates is accused. An incident which may perhaps really have occurred in the family of Euthyphro, a learned Athenian diviner and soothsayer, furnishes the occasion of the discussion.
