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.
Socrates
Evaluation of and reaction to Socrates has been undertaken by both historians and philosophers from the time of his death to the present day with a multitude of conclusions and perspectives. Although he was not directly prosecuted for his connection to Critias, leader of the Spartan-backed Thirty Tyrants, and "showed considerable personal courage in refusing to submit to [them]", he was seen by some as a figure who mentored oligarchs who became abusive tyrants, and undermined Athenian democracy. The Sophistic movement that he railed at in life survived him, but by the 3rd century BC, was rapidly overtaken by the many philosophical schools of thought that Socrates influenced.
