The setting of "Fahrenheit 451" is an unnamed American city in the future. The city in the novel is unnamed primarily because Ray Bradbury, the author, intended for readers to imagine that it could be any and every city, including their own.
The title of the novel is the temperature at which books burn. Book burning is the occupation of the book's protagonist, Guy Montag. The crux of the novel is that the futuristic society is not an extremely advanced one but one that has squandered learning and knowledge in favor of television and radio. It is meant to be a cautionary tale about the value of education and learning.
