Well translated and the notes help to expand on the arguments being had in these three dialogues.
The first Dialogue is Euthyphro, and concerns a young man of the same name as the dialogue, he is planning to take his father to court for murder and thinks that bringing justice by prosecuting his father is his religious duty. Socrates pokes and prods at Euthyphro’s arguments and sees if he does indeed understand justice and the duty we have to the gods.
The second dialogue is Defence of Socrates, it is known to have several different titles such as The Apology, The last words of Socrates etc. This dialogue is a legal defence of Socrates put to the Athenian court by Socrates himself. In this defence he takes on the charges against him by Meletus: that of corrupting the youth and being an Atheist. Socrates not only defends himself, but also the Socratic method as a whole, while holding to the fact he possesses wisdom by knowing he is not wise nor the wisest.
The third dialogue is Crito, which is named after the only person in this dialogue except Socrates. In this dialogue Crito has visited Socrates in jail in order to talk to his old friend, but also to suggest escape as if he doesn’t Socrates will be hurting Crito by removing himself as a friend. Socrates probes Crito’s arguments, rather than his motives, trusting him as a friend, but also wishing to explain why he doesn’t escape, but instead will be accepting this injustice and thus his own execution by the state.
