Phaedo
From Conservapedia
The Phaedo (Greek Φαίδων) is a famous dialogue written sometime in the early 4th-century B.C. by the Greek philosopher Plato.
The dialogue occurs in Socrates' prison cell, before he is to be executed by drinking hemlock. In it, he seeks to prove the immortality of the soul, the existence of the afterlife, and immorality of suicide. This has made the piece influential among Christian scholars, although the beliefs in reincarnation and the transmigration of souls are given favorable treatment. A great deal of the dialogue is given to discussion of Plato's well-know "theory of forms."
Compared to other Socratic dialogues of Plato, the Phaedo is written in an unusual form, as the entire dialogue is presented within another dialogue taking place after Socrates' death: that between Phaedo (who was present in the cell) and Ephecrates (who, not having been present in the cell, was eager to hear of Socrates' last thoughts before dying). The main chracters engaging in the inner dialogue are Socrates, Cebes, and Simmias.
