Dostoevsky's final and greatest novel asks whether God exists and whether, without God, everything is permitted. The three Karamazov brothers represent different responses to these questions: Ivan the intellectual atheist, Dmitri the passionate sensualist, Alyosha the man of faith. Their father is murdered; the wrong brother stands trial. The Grand Inquisitor chapter is the most famous philosophical passage in fiction. Dostoevsky died three months after completion, planning a sequel. What remains is complete in itself, the fullest expression of his vision.
