The Brothers Karamazov tells the story of a single ruined family. Fyodor Pavlovitch Karamazov is a greedy, lecherous landowner who has neglected each of his children; the novel gathers his three legitimate sons (the hot-blooded Dmitri, the coldly intellectual Ivan, and the youngest, the novice monk Alyosha) together with his servant Smerdyakov, around a quarrel over money and a woman that builds toward the father's murder.
The book is far less a mystery than a debate. Dmitri is consumed by passion and shame, oscillating between nobility and disgrace; he sees that beauty itself is ambiguous, that God and the devil are at war in the human heart. Ivan, who cannot accept a world built on the suffering of innocent children, advances the chilling idea that if there is no immortality of the soul, then everything is lawful. Alyosha carries the counterweight of faith, learned at the feet of the dying elder Zossima.
At the novel's center is Ivan's prose poem, 'The Grand Inquisitor.' Christ returns to sixteenth-century Seville and is arrested by the aged Inquisitor, who tells Him that men do not want freedom but bread, security, and someone to bow before. The Church, the Inquisitor says, has corrected Christ's work, founding human happiness on miracle, mystery, and authority. It accepts the burden of choice so that the weak may live like contented children.
Set against this is the teaching of Father Zossima, recorded after his death. Where Ivan reasons from the suffering of the world to rebellion, Zossima answers with active love, which he calls a harsh and dreadful thing compared with love in dreams. His creed is that each person is responsible to all for everything, that one must love all of God's creation down to every leaf and grain of sand, and that hell is simply the suffering of being unable to love.
When the father is killed, suspicion falls on Dmitri, and his trial becomes a public reckoning with the family's guilt. The real responsibility is more tangled than the verdict allows, and Ivan is broken by the discovery that his idea has had consequences he never intended. Yet the book does not end in despair: it closes with Alyosha among a group of boys at a child's funeral, promising that they will all rise again and meet with joy, insisting that they remember a moment of goodness shared together.
