Fyodor Dostoyevsky was a Russian novelist, short story writer, essayist, and philosopher, considered one of the greatest psychological novelists in world literature. He was born on November 11, 1821, in Moscow, Russia, and died on February 9, 1881, in Saint Petersburg. His most acclaimed works include "Crime and Punishment," "The Idiot," "Demons," and "The Brothers Karamazov." Dostoyevsky is known for exploring complex themes of morality, free will, existentialism, and the human psyche. His characters often grapple with profound philosophical and psychological issues, as his narratives delve into the depths of the human soul. His writing style is characterized by deep psychological insight, ethical dilemmas, social commentary, and engagement with religious themes, particularly the struggles of faith in an increasingly secular society. His own life experiences, including a mock execution, imprisonment in Siberia, and a turbulent gambling addiction, heavily influenced his writing. Through his novels, Dostoyevsky changed the landscape of literature, leaving a lasting legacy on both Russian and world literature.
