Phaedo
Socrates offers four arguments for the soul's immortality:The scene is set in Phlius where Echecrates who, meeting Phaedo, asks for news about the last days of Socrates. Phaedo explains why a delay occurred between his trial and his death, and describes the scene in a prison at Athens on the final day, naming those present. He tells how he had visited Socrates early in the morning with the others. Socrates' wife Xanthippe was there, but was very distressed and Socrates asked that she be taken away. Socrates' relates how, bidden by a recurring dream to "make and cultivate music", he wrote a hymn and then began writing poetry based on Aesop's Fables.
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).
