Book: Phaedo

Setting and Frame

Phaedo recounts to the Pythagorean Echecrates the final day of Socrates in an Athenian prison, offering an eyewitness narrative that blends memory with philosophy. Present are Crito, Simmias, Cebes, Apollodorus, and others. The scene opens with Socrates freed from his fetters, remarking on the strange kinship of pleasure and pain as he rubs his aching leg, an image that foreshadows the dialogue’s exploration of the soul’s release from the body. Because a sacred embassy delayed executions, Socrates has time for a long conversation, which he dedicates to examining why the philosopher need not fear death.

Philosophy as Preparation for Death

Socrates argues that genuine philosophy is a training for dying. The body distracts with appetites, diseases, and sensory illusions; only a soul disentangled from bodily interference can grasp unchanging realities. Philosophers practice this separation in life by moderating bodily desires and fixing their attention on intelligible truths. Suicide is forbidden because humans are the possessions of the gods, yet desiring the right kind of death, a release into wisdom, follows from the philosopher’s vocation.

Arguments for the Soul’s Immortality

Socrates offers several lines of reasoning. First, the cyclical argument claims that all things come to be from their opposites; as waking comes from sleeping, so living comes from the dead, implying a recurrent process in which souls exist before rebirth. Second, the theory of recollection holds that we recognize Equal itself or Beauty itself in ways no sensory object can deliver, suggesting the soul’s prior acquaintance with the Forms before embodiment. Third, the affinity argument distinguishes the visible, composite, and perishable (body) from the invisible, simple, and unchanging (Forms). The soul, being more akin to the latter, is likely to persist and to fare according to its purity or entanglement with the bodily.

Objections from Simmias and Cebes

Simmias proposes the attunement analogy: perhaps the soul is to the body as harmony is to a lyre, an emergent arrangement that perishes when the instrument breaks. Cebes offers the weaver analogy: a weaver outlasts many coats but eventually dies; likewise, the soul might outlast many bodies yet not be immortal. These challenges provoke a methodological turn. Socrates warns against misology, the hatred of argument that arises when one is too easily deceived by plausible reasoning. Instead, one should test arguments patiently and seek a stable starting point.

Method, Forms, and Causes

To answer, Socrates adopts a “second sailing, ” relying on hypotheses about the Forms as explanatory causes. If anything is beautiful, it is because it participates in Beauty itself; the cause is not merely size, shape, or mixture but the Form. Against Simmias, Socrates notes that harmony cannot exist prior to or govern its instrument, while the soul often rules and opposes bodily impulses; moreover, recollection implies the soul’s prior existence, which a mere harmony cannot have. Against Cebes, he argues for the soul’s essential relationship to life: just as fire cannot admit cold, the soul will not admit death. Therefore it is deathless, leaving only the question of moral purification to determine its postmortem state.

The Myth of the Afterlife

Socrates closes with a mythic geography of the cosmos. After judgment, incurably unjust souls are consigned to Tartarus; curable ones undergo punishments and purifications; moderate souls return to embodied lives; the purified lover of wisdom ascends to dwell with the gods. The earth, he says, is far more wondrous than we perceive, crisscrossed by rivers and chasms, with a pure realm above where true colors and realities are seen. The tale is offered not as demonstration but as a fitting story to live and die by, encouraging virtue and hope.

Death of Socrates and Legacy

Calm and attentive to his companions’ well-being, Socrates bathes to spare the women trouble, speaks tenderly with his friends, and drinks the hemlock without hesitation. As the numbness rises, he reminds Crito: “We owe a cock to Asclepius; pay the debt and do not neglect it, ” a sign that death is a cure for the soul’s ills. Phaedo concludes that no man he knew was wiser, more just, or more courageous, and the dialogue endures as a meditation on argument, character, and the soul’s fate.
