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.
Socratic problem
Socrates — who is often credited with turning Western philosophy in a more ethical/political direction and who was put to death by the democracy of Athens in May 399 BC — was Plato's mentor. Plato, like some of his contemporaries, wrote dialogues about his teacher. Much of what is known about Socrates comes from Plato's writings; however, it is widely believed that very few, if any, of Plato's dialogues can be verbatim accounts of conversations between them or unmediated representations of Socrates' thought. Many of the dialogues seem to use Socrates as a device for Plato's thought, and inconsistencies occasionally crop up between Plato and the other accounts of Socrates; for instance, Plato has Socrates denying that he would ever accept money for teaching, while Xenophon's "Symposium" clearly has Socrates stating that he is paid by students to teach wisdom and that this is what he does for a living.
