 Paranoid fiction is works of literature that explore the subjective nature of reality and how it can be manipulated by forces in power.These forces can be external, such as a totalitarian government, or they can be internal, such as a character's mental illness or refusal to accept the harshness of the world they are in.Philosophical fiction is fiction in which a significant proportion of the work is devoted to a discussion of the sort of questions normally addressed in discursive philosophy.
