Dostoevsky’s masterpieces, including Crime and Punishment and The Brothers Karamazov, are noted for their intense philosophical and religious themes. After a mock execution and years of exile in Siberia, his work took on a profound concern with suffering, redemption, and the struggle between faith and reason. He is considered one of the greatest psychologists in world literature, influencing countless writers and philosophers with his portrayal of the 'underground' man.
