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.
Apology (Plato)
Socrates responds to the death-penalty verdict by first addressing the jurors who voted for his death. He says that their condemnation of him resulted not from a lack of arguments, but from a lack of time — and an unwillingness to pander for pity, as expected of a man condemned to death. Socrates repeats that the prospect of death does not absolve him from following the path of goodness and truth. He prophesies that younger and harsher critics shall follow in his stead, philosophers who will spur ethical conduct from the citizens of Athens, in a manner more vexing than that of Socrates (39d).
