Plato's dialogue dramatising the last hours of Socrates in the Athenian prison in 399 BCE — the conversation he holds with Phaedo of Elis, Cebes, Simmias and other companions on the day of his execution, and the four arguments he offers for the immortality of the soul. The dialogue ends with the drinking of the hemlock and one of the most-quoted death scenes in Western literature.
Alongside the immortality arguments it develops the theory of recollection, the soul's kinship with the Forms, and the philosophical life as a 'practice for dying'.
Those who pursue philosophy aright study nothing but dying and being dead.
p. Stephanus 64a · On the Philosophical Life
First lines
Were you yourself, Phaedo, in the prison with Socrates on the day when he drank the poison? — I myself was there, Echecrates.

Reception
One of the most influential dialogues in the history of philosophy — the primary Platonic source for the Christian and Neoplatonic doctrine of an immortal soul, and the model for every later philosophical death scene from Cicero to Boethius. Modern criticism since David Gallop and David Bostock has scrutinised the immortality arguments themselves and found them wanting on technical grounds, while granting the dialogue's literary and pedagogical achievement is unmatched. The closing pages, with Socrates calmly correcting his weeping friends, have shaped the Western image of philosophical death for two and a half millennia.
Frequently asked
What is the Phaedo about?
The Phaedo dramatises the last hours of Socrates in an Athenian prison in 399 BCE. Socrates converses with Phaedo of Elis, Cebes, Simmias and other companions on the day of his execution, offering four arguments for the immortality of the soul. The dialogue closes with the drinking of hemlock and has defined the Western image of the philosophical death for two and a half millennia.
What are the four arguments for immortality in the Phaedo?
Socrates argues that (1) the soul cycles between life and death (the Cyclical Argument); (2) learning is recollection of knowledge the soul possessed before birth (the Argument from Recollection); (3) the soul, being akin to the immortal Forms, cannot be dissolved (the Affinity Argument); and (4) the soul by its nature participates in Life and therefore cannot admit Death (the Final Argument). Modern scholarship — particularly David Gallop and David Bostock — finds each argument philosophically vulnerable, while granting the dialogue's unmatched literary power.
Why is the Phaedo important for the history of religion?
The Phaedo is the primary Platonic source for the doctrine of an immortal, immaterial soul. Christian theology from Origen onwards and the Neoplatonic tradition from Plotinus drew on it directly. It supplied the philosophical vocabulary — soul, form, recollection, the intelligible world — that shaped both Western metaphysics and Christian eschatology for over a millennium.
