On his execution day, calm and even cheerful, Socrates argues that the soul outlives the body — four times over — and then drinks the hemlock.

Body and soul
The “affinity” argument: the body is like the things that decay — visible, changing, breakable — while the soul is more like the Forms it reasons about: invisible, unchanging, and so, Socrates argues, not the kind of thing that can die. It is one of four proofs the dialogue stacks, none meant to stand alone.
The shape of the argument
Why face death calmly
Death is the soul set free from the body, and philosophy has been practice for it all along.
1 · Opposites
The living come from the dead and the dead from the living — so the soul must persist between lives.
2 · Recollection
We recognize the Forms as if remembering them — so the soul knew them, and existed, before birth.
3 · Affinity
The soul resembles the invisible, unchanging Forms it grasps, so it is the imperishable kind of thing.
The objections
Simmias: maybe the soul is just the body’s tuning, gone when the lyre breaks. Cebes: it may outlast many bodies and still wear out.
4 · The final proof
The soul brings life, so it can no more admit death than fire can admit cold — therefore deathless.
The hemlock
A closing myth of the true earth, then the poison, the covered face, and a last debt owed to the god of healing.
The cast
Socrates — the condemned philosopher, calm and even cheerful, arguing the soul outlives the body
Phaedo — narrates the whole last day afterward, from Phlius
Echecrates — the listener whose questions pull the story out of Phaedo
Cebes — the sharp objector: lasting a long time isn’t the same as never dying
Simmias — objects that the soul may be the body’s tuning, gone when the lyre breaks
Crito — the old friend who receives the last words about the cock owed to Asclepius
The famous bits
Practice for deathThe thesis
The philosopher spends his life freeing the soul from the body — so death is the thing he has been training for.
Learning is rememberingRecollection
We recognize the Forms as if recovering them — proof the soul knew them, and existed, before we were born.
The broken lyreThe objection
Simmias: maybe the soul is just the body’s tuning, and dies the moment the instrument breaks.
The final argumentThe summit
The soul brings life, so it can no more admit death than fire can admit cold — therefore it cannot die.
The last wordsThe death
“Crito, I owe a cock to Asclepius” — the enigmatic close, as if death were the cure for a long illness.
The likely taleThe myth
A picture of the true earth and the soul’s journey after death — offered not as fact but as a story worth the risk.
