Things that have opposites are generated out of those opposites, as waking comes from sleeping; so the living come from the dead and the dead from the living.
It gives the reader a way to argue that the cycle of life and death must continue rather than ending once in death.
What is simple, invisible, and unchanging tends not to dissolve, while what is composite and changing tends to scatter; the soul resembles the former, the body the latter.
It lets the reader judge the soul's durability by what kind of thing it most resembles, rather than by what the eyes can see.
Truth is reached when the soul reasons in its own clearness, set apart as far as possible from the eyes, ears, and appetites of the body.
It turns the search for knowledge into a discipline of detachment, treating bodily distraction as the main obstacle to understanding.
Summary
Phaedo recounts the last hours of Socrates, narrated by his friend Phaedo to listeners who were not present. Condemned to die and awaiting the cup of poison, Socrates spends the day calmly discussing whether the soul survives death, surrounded by companions including Simmias and Cebes.
The dialogue opens with Socrates explaining why the true philosopher does not fear death. He defines death as the separation of the soul from the body, and he argues that philosophy has always aimed at exactly this release: gathering the mind into itself and away from the deceptions of the senses. A life of such practice, he says, is in effect a long rehearsal for dying.
Socrates then offers several arguments that the soul does not simply perish. He appeals to the way opposites come from opposites, so that the living come from the dead as the dead from the living. He revives the claim that learning is recollection of knowledge the soul possessed before birth, which implies the soul existed beforehand. He argues that the soul, being invisible and unchanging in nature, resembles the divine and lasting rather than the perishable body.
His friends press hard objections. Simmias suggests the soul might be a harmony of the body, vanishing when the body is destroyed; Cebes warns that the soul might outlast many bodies yet still wear out at last. Socrates answers these in turn, finally building toward the claim that the soul, as the principle that brings life, cannot admit its opposite and so cannot die.
The work closes not with triumphant proof but with steadiness. Socrates tells a long myth of the soul's fate after death, bathes, takes leave of his family, and drinks the poison without complaint. His composure in the face of death is offered as the lived demonstration of everything the arguments tried to show. His last request is that a debt be paid, and he dies in peace among his friends.

Selected Quotes
Is it not the separation of soul and body?
and justice, and courage, and wisdom herself are the purgation of them.
Then the soul is more like to the unseen, and the body to the seen?
