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.
Prodicus
Prodicus of Ceos (; , "Pródikos ho Keios"; c. 465 BC – c. 395 BC) was a Greek philosopher, and part of the first generation of Sophists. He came to Athens as ambassador from Ceos, and became known as a speaker and a teacher. Plato treats him with greater respect than the other sophists, and in several of the Platonic dialogues Socrates appears as the friend of Prodicus. One writer claims Socrates used his method of instruction. Prodicus made linguistics and ethics prominent in his curriculum. The content of one of his speeches is still known, and concerns a fable in which Heracles has to make a choice between Virtue and Vice. He also interpreted religion through the framework of naturalism.
