Crito has characteristics of both early and mature dialogues. The major difficulty in placing
However, there is much else to suggest it is an early work. Thematically, it is linked to
This question is obviously linked to the next one: whether or not Socrates' argument is consistent. Crito's argument seems to rest more heavily on the notion that justice consists in helping one's friends and hurting one's enemies, suggesting that it would be wrong to help one's enemies. Socrates seems to want to argue against that, suggesting that retaliation of any kind is wrong. For him, justice consists in obeying the Laws as they have been set down. So they do seem to have differing moral positions, and they do seem irreconcilable to the extent that both see the other's position as unjust. Crito does seem increasingly to agree with Socrates as Socrates clarifies his argument, but Socrates never directly addresses Crito's question of whether it would be unjust to help his enemies. Instead of refuting Crito, he simply side-steps him, giving priority to the question of whether or not one has a right to break the Laws.
This is a main question of the dialogue, and more detailed answers have been given in the running Summary & Analysis sections and the Full Work Analysis. It does seem that there is some inconsistency here. Plato is committed to the claim that Socrates' accusers are acting unjustly, but that the Laws are just. Socrates is thus wrongfully imprisoned and will be wrongfully executed, but he cannot counteract these wrong judgments because they are secured by the Laws. But if the Laws are just, how is it that they permit such injustice? And if the Laws are unjust, what compulsion does Socrates have to abide by them? One might reply that the Laws are fixed in place and have been applied unjustly in this case, but that to go against them would be to attack them in an unjust manner. However, one could reply to this objection by saying that if the Laws are unjustly applied, Socrates is allowing the Laws to come to harm in complacently accepting this injustice.
