Phaedo a guided tour

c. 360 BC · Socratic dialogue on the immortality of the soul

Socrates spends his last day in prison arguing that death is not a misfortune. The hemlock waits in the next room. His friends have come early and will not leave.

The book in brief

Phaedo is the third panel of Plato's death sequence — Apology gave the trial, Crito the refusal to escape, and Phaedo the day itself. The frame is a retelling: Phaedo of Elis, who was in the cell, reports the conversation to Echecrates of Phlius sometime afterward. We hear the story because someone who was there survived to tell it, and we hear it whole because the conversation ran from morning to sundown.

The dialogue moves through four arguments for the soul's immortality — from opposites, from recollection, from affinity with the Forms, and from the Form of Life itself — and lets each argument be pushed and tested. Cebes and Simmias, the two Theban philosophers in the cell, raise the objections you would raise, and Socrates takes them seriously. Between and around the arguments is the texture of a room: a man who was kind, a friend who cannot stop weeping, Crito's unceasing practical worry, and at the end the cup, the walk, and the words about a debt to Asclepius.

Section 1

The frame — Phaedo sets the scene

Phaedo of Elis meets Echecrates of Phlius. Echecrates has heard that Socrates died by poison, but knows nothing more — no Athenian traveler has passed through Phlius, and the trial reports that reached them were incomplete. He wants the whole account. Phaedo agrees, and says that being reminded of Socrates — whether he is speaking about him or someone else is — is always a pleasure. He explains the delay between the trial and the death: the sacred ship to Delos had been crowned the day before the trial, and during its voyage the city was not allowed to carry out executions. So Socrates lay in prison for weeks more. Phaedo describes the friends who were there — Apollodorus already weeping, Cebes and Simmias up from Thebes, Crito — and says that being near Socrates that day produced a feeling he had never felt before: pity and pleasure mixed, an unfamiliar compound.

Section 2

Why the philosopher should not fear death

Socrates has just dismissed his wife Xanthippe, who was weeping too loudly for the kind of conversation he wants to have. He turns to Cebes and Simmias and makes the claim that will anchor the entire dialogue: the true philosopher not only does not fear death but positively desires it. The men around him are skeptical — they have heard that the philosopher desires death, but it has always seemed an odd thing to say of a wise man. Socrates explains: death is the separation of soul from body. Philosophy is the practice of exactly that separation — turning away from the body and its appetites toward what the mind alone can grasp. The philosopher who has spent a life seeking truth through the mind has spent a life loosening the soul from the body. Death finishes what philosophy began. To fear it is a contradiction in terms.

Section 3

The first argument — from the cycle of opposites

Socrates turns to the first argument: the cycle of opposites. In nature, everything that has an opposite is generated from its opposite — the larger from the smaller, the stronger from the weaker, the awake from the asleep. Life and death are such a pair. If the dead come from the living, then the living must come from the dead. The process must be circular, or else everything would eventually run down to one pole. Souls must persist between lives for the living to be born from the dead at all. Cebes confirms that this follows. Socrates adds the argument from recollection as a second line of support — knowledge as memory of a time before birth — which Cebes says he learned from Socrates before.

Section 4

The second argument — from recollection

Simmias wants the argument from recollection laid out more fully — he has heard it before but wants to hear it again. Socrates obliges. We recognize equality, but no two physical objects are ever truly equal. We grasp beauty, but no particular beautiful thing exhausts what beauty is. To recognize the imperfect instance as an imperfect instance of the Form, we must already know the Form. Since we did not acquire this knowledge in this life — we were born already capable of recognizing Equality when we encountered equal sticks — we must have had it before birth. The soul existed before it entered the body. And if the soul existed before, it is reasonable to think it will continue after.

Section 5

The third argument — from affinity with the Forms

The third argument runs through the longest section of the dialogue. Socrates asks Cebes and Simmias to consider two kinds of things: the visible, composite, changing, mortal; and the invisible, simple, unchanging, eternal. The Forms belong to the second kind. The body belongs to the first. The soul, by contrast, is most itself when it thinks — when it is engaged with the eternal, not the perishable. The soul therefore resembles the eternal and belongs with it. When the body dies, the soul, if it has not been infected by the body's way of valuing things, withdraws to its own realm. He then describes what becomes of different kinds of souls after death — the philosophical soul goes to its proper home; the unphilosophical soul wanders, weighted by attachments to the body it could not leave behind.

Section 6

The crisis — Simmias and Cebes push back

Simmias and Cebes intervene with two objections that land hard. Simmias proposes the harmony objection: the soul might be to the body what a tune is to a lyre — a harmony of the body's physical elements, destroyed when those elements are disrupted. The analogy is damaging because it would mean the soul has no existence independent of the body that produces it. Cebes proposes the worn-cloak objection: even if the soul is stronger than the body and outlasts it through many lives, it might still wear out at the last and perish. Neither objection denies the soul's longevity; both deny its immortality. Phaedo describes the crisis that follows: the company had been convinced, and now they were unsure what argument they could trust.

Section 7

The fourth argument — from the Form of Life

Socrates answers Simmias first. The harmony objection fails because harmonies admit of degrees — a lyre can be more or less in tune — but souls cannot be more or less a soul. Every soul is equally a soul. Furthermore, the account of virtue and vice that everyone accepts depends on the soul being able to rule the harmony of the body, not be it. He then turns to the deep argument: there is a difference between opposites and the things that bring opposites. Snow is not cold — it brings cold. Fire is not hot — it brings heat. When the cold approaches fire, fire does not become cold; it retreats or perishes first. Now: the soul brings life wherever it goes. What brings life cannot admit death. It retreats or perishes — but it cannot become dead. The soul is immortal. The mythic account of the afterlife follows.

Section 8

The myth and the farewell

The arguments are done. Socrates offers the myth of the earth's true shape — a place far larger and more beautiful than what we see — and the fate of souls after death, in language that is explicitly mythic rather than dialectical. He says a reasonable person shouldn't insist the description is exactly true, but the venture of belief is a noble one. He closes with practical instructions for Cebes and Simmias and the others: take care of yourselves. Then he handles Crito's question about the body: don't say "here we bury Socrates" — you are burying the body only. He gets up to bathe. His children and the women of the household are brought in; he speaks with them and sends them away. He returns to the friends and sits with them in the last of the afternoon.

Section 9

The cup, the walk, the last words

The prison guard arrives and tells Socrates it is time. He praises the man for the kindness he has shown throughout the imprisonment and weeps as he goes. Socrates tells Crito to bring the cup if it is ready. Crito tries to delay — the sun is still on the hilltops; others wait until the last moment. Socrates refuses. He would not gain anything by drinking the poison a little later; he would only look foolish to himself, clinging to a life already forfeit. The cup is brought. He asks if he may pour a libation; the attendant says there is only enough for the dose. He accepts this, prays that his journey may be fortunate, and drinks the cup steadily and without distaste. The friends, who have held together through the long day, break. Apollodorus howls. Crito cannot watch. Socrates rebukes them mildly. He walks until his legs grow heavy, lies down. The numbness climbs. He uncovers his face and speaks his last words. Crito closes his eyes and mouth.

Key themes

5 threads that hold the book together. Full analysis →

Philosophy as preparation for death

The opening claim is the one that will scandalize a modern reader and that Socrates means literally. The true philosopher has been practicing dying all along. Philosophy is the rehearsal; death is the performance.

The four arguments for immortality

Plato gives Socrates four arguments and lets each one be tested. From opposites. From recollection. From affinity with what does not change. From the Form of Life itself. The arguments are real — Cebes and Simmias raise the objections you would raise.

The Forms — what the soul belongs to

The theory of Forms underlies every argument in the dialogue. There is Equality itself, and there are equal sticks. The Form is one, eternal, unchanging; the particulars are many, transient, given to the senses. The soul is the part of us that can reach the originals.

The objections — and the crisis they cause

Simmias and Cebes raise the two strongest objections in the dialogue. The harmony objection and the worn-cloak objection. For a moment, the company despairs. Echecrates, hearing the story later, says he felt the same.

The death itself

The final pages are written with a restraint that has not been improved on in two and a half thousand years. Socrates bathes, sends the women home, drinks the cup without distaste, walks until his legs grow heavy. His last words are about a debt.
