Crito
The dialogue takes place in Socrates' prison cell, where he awaits execution. He is visited before dawn by his old friend Crito, who has made arrangements to smuggle Socrates out of prison to the safety of exile. Socrates seems quite willing to await his imminent execution, and so Crito presents as many arguments as he can in order to persuade Socrates to escape. On a practical level, Socrates' death will reflect badly on his friends--people will think they did nothing to try to save him. Also, Socrates should not worry about the risk or the financial cost to his friends; these they are willing to pay, and they have also arranged to find Socrates a pleasant life in exile. On a more ethical level, Crito presents two more pressing arguments: first, if he stayed, he would be aiding his enemies in wronging him unjustly, and would thus be acting unjustly himself; and second, that he would be abandoning his sons and leaving them without a father.
Xenophon
Both Plato and Xenophon wrote an "Apology" concerning the death of Socrates. The two writers seem more concerned about answering questions that arose after the trial than about the actual charges. In particular, Xenophon and Plato are concerned with the failures of Socrates to defend himself. The Socrates that Xenophon portrayed was different from Plato’s in multiple respects. Xenophon asserts that Socrates dealt with his prosecution in an exceedingly arrogant manner, or at least was perceived to have spoken arrogantly. Conversely, while not omitting it completely, Plato worked to temper that arrogance in his own "Apology". Xenophon framed Socrates’ defense, which both men admit was not prepared at all, not as failure to effectively argue his side, but as striving for death even in the light of unconvincing charges. As Danzig interprets it, convincing the jury to condemn him even on unconvincing charges would be a rhetorical challenge worthy of the great persuader. Xenophon uses this interpretation as justification for Socrates’ arrogant stance and conventional failure. By contrast, Plato does not go so far as to claim that Socrates actually desired death, but seems to argue that Socrates was attempting to demonstrate a higher moral standard and teach a lesson, although his defence failed by conventional standards. This places Socrates in a higher moral position than his prosecutors, a typical Platonic example of absolving "Socrates from blame in every conceivable way."
