Early works of science fiction often are included in the educational system, especially in primary schools. The concise, idiomatic prose favored in the genre, coupled with the tendency toward overtly dramatic plotlines, serve to make science fiction approachable to young readers.
Few high-school level English programs can be found that do not contain George Orwell's dystopian novel 1984, the most celebrated work dealing with the common science-fictional theme of a government that grows so powerful as to regulate all aspects of the lives of its citizens. This theme often is described as "Orwellian," a term that has found its way into the popular (and literary) lexicon.
Orwell's Animal Farm, a more fantasy-based novel, presents a different way at approaching the same overall theme. It is common for writers of genre fiction to write in multiple genres, including several authors who have achieved critical acclaim in more than one-such as Ursula K. Le Guin, Robert Silverberg, Orson Scott Card and many others.
Ray Bradbury's Fahrenheit 451, a similarly dystopian (and Orwellian) novel, is another literature-class staple. Bradbury is known as a pure stylist, even considering his background in science fiction, and is an example of the sort of author that whose work slowly is earning respect among literary purists for genre fiction as a whole.
