Dostoevsky was a Russian novelist, short story writer, essayist, journalist and philosopher. Dostoyevsky's literary works explore human psychology in the troubled political, social, and spiritual atmosphere of 19th-century Russia. Many of his works contain a strong emphasis on Christianity, and its message of absolute love, forgiveness and charity, explored within the realm of the individual, confronted with all of life's hardships and beauty. He began writing in his 20s, and his first novel, Poor Folk, was published in 1846 when he was 25. His major works include Crime and Punishment (1866), The Idiot (1869), Demons (1872) and The Brothers Karamazov (1880). His output consists of eleven novels, three novellas, seventeen short novels and numerous other works. Many literary critics rate him as one of the greatest and most prominent psychologists in world literature. His novella Notes From Underground is considered to be one of the first works of existentialist literature.
