Crito (/ˈkraɪtoʊ/ KRY-toh or /ˈkriːtoʊ/ KREE-toh; Ancient Greek: Κρίτων [krítɔːn]) is a dialogue by the ancient Greek philosopher Plato. It depicts a conversation between Socrates and his wealthy friend Crito regarding justice (δικαιοσύνη), injustice (ἀδικία), and the appropriate response to injustice. Socrates thinks that injustice may not be answered with injustice, and refuses Crito's offer to finance his escape from prison. The dialogue contains an ancient statement of the social contract theory of government.
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.
