Dostoyevsky's novels are renowned for their deep psychological insight and exploration of faith, morality, free will, and human suffering. His major works include Notes from Underground (1864), considered a founding text of existentialism; Crime and Punishment (1866), the story of the tormented murderer Raskolnikov; The Idiot (1869), featuring the saintly Prince Myshkin; Demons (1872), a study of political fanaticism; and his masterpiece, The Brothers Karamazov (1880), a profound meditation on God, doubt, and redemption.
Despite personal struggles with epilepsy, debt, and gambling, Dostoyevsky produced works of extraordinary depth. He profoundly influenced modern literature and philosophy, inspiring writers and thinkers such as Nietzsche, Freud, Kafka, and Camus.
