 At the center of Plato’s shorter ethical works is the  Apology of Socrates,  which consists of a speech purportedly given by Socrates at his trial, and is probably the closest of Plato’s works to the historical Socrates. The Apology is closely linked to two other works. The first is the  Euthyphro,  which shows Socrates discussing reverence as he is about to report to court for his indictment, an indictment that includes by implication a charge of irreverence. The second is the  Crito,  which shows Socrates in prison on the day before his execution, defending his decision to accept the penalty rather than corrupt the law by bribing his way out of prison and away from Athens. The Crito argument depends on a principle that is the bedrock of Socratic ethics: that it is never right to do wrong, even in return for wrong (49ab). This bedrock principle rules out the view that one should do right by one’s friends and wrong by one’s enemies, a view that had roots in Greek tradition.
