The Brothers Karamazov follows the turbulent lives of the Karamazov family—sensualist father Fyodor and his sons Dmitri, Ivan, and Alyosha—culminating in a patricide and a dramatic trial. Through their conflicts and conversations, Dostoevsky explores faith, doubt, free will, and the problem of evil, most famously in the Grand Inquisitor episode. The novel weaves psychological depth, philosophical inquiry, and spiritual searching into a vast, polyphonic masterpiece.
