High Quality Content by WIKIPEDIA articles! The themes in the writings of Russian writer Fyodor Dostoyevsky, which surpass novels, novellas, short stories, essays, epistolary novels, poetry,spy fiction and suspense, include suicide, poverty, human manipulation and morality. Religious themes are found throughout his works, especially after his release from prison in 1854. His early works emphasised realism and naturalism, as well as social issues such as the differences between the poor and the rich. Influences from other writers are evident especially, in his early works, leading to accusations of plagiarism, but his style gradually developed over his career. Elements of gothic fiction, romanticism and satire can be found in his writings. Dostoyevsky was "an explorer of ideas", greatly affected by the sociopolitical events occurring during his lifetime. After his release from prison, his writing style changed drastically, moving away from his earlier "sentimental naturalism", and featuring more psychological and philosophical themes. Much of his later works are characterised by autobiographical elements.
