Philosophical fiction refers to the class of works of fiction which devote a significant portion of their content to the sort of questions normally addressed in discursive philosophy. These might include the function and role of society, the purpose of life, ethics or morals, the role of art in human lives, and the role of experience or reason in the development of knowledge. Philosophical fiction works would include the so-called novel of ideas, including some science fiction, utopian and dystopian fiction, and the Bildungsroman.
