Why is Fahrenheit 451 a Classic?

While the novel is most often classified as a work of science fiction, it is first and foremost a social criticism warning against the danger of censorship. Fahrenheit 451 uses the genre of science fiction, which enjoyed immense popularity at the time of the book's publication, as a vehicle for his message that unchecked oppressive government irreparably damages society by limiting the creativity and freedom of its people. In particular, the "dystopia" motif popular in science fiction - a futuristic technocratic and totalitarian society that demands order and harmony at the expense of individual rights - serves the novel well and makes it a classic even today.
