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.
The unexamined life is not worth living
This statement relates to Socrates' understanding and attitude towards death and his commitment to fulfill his goal of investigating and understanding the statement of the Pythia. Socrates understood the Pythia's response to Chaerephon's question as a communication from the god Apollo and this became Socrates's prime directive, his "raison d'etre". For Socrates, to be separated from elenchus by exile (preventing him from investigating the statement) was therefore a fate worse than death. Since Socrates was religious and trusted his religious experiences, such as his guiding daimonic voice, he accordingly preferred to continue to seek the truth to the answer to his question, in the after-life, than live a life not identifying the answer on earth.
