Bradbury has a distinctive, engaging style. In this novel, his dreamlike science fiction details events and technologies not unbelievable to contemporaneous readers. This book is mainly third person limited, and readers are constrained to Guy's thoughts, understandings, and memories. But the style varies depending on what mood Bradbury wants to inflect. Often, he uses an impressionist style to convey events and memories with both brevity and detail. Descriptive lists of adjectives, brief flashbacks, and metaphors all help the reader understand this unusual society and its technologies, as well as Guy's psychology.
Fahrenheit 451 has a quick, active plot—a lot happens in relatively few pages. However, Bradbury's effective, economic writing style allows him to give Guy and the other characters a lot of depth and complexity in relatively few words. Likewise, his poetic descriptions, intentionally constructed sentences, and unique choices of words all provide the reader with vivid imagery while leaving room open for interpretation. Bradbury also has an incredible imagination, as Fahrenheit 451's world-building illustrates so well. He pulls inspiration from current events (like McCarthyism) and rapidly improving technologies (like television), but from those starting points he develops a fully-fleshed dystopia, recognizable to modern-day readers yet eerily different from our own society.
Bradbury also manages to fit philosophical discussions regarding art, censorship, and human nature in Fahrenheit 451. Through characters like Faber, Granger, and Beatty, Bradbury presents multiple perspectives on some of the novel's most important issues. Careful readers will note that Bradbury, through Faber especially, suggests ideas about many things, including the potential of television to hold the same level of complexity as a novel. Although Fahrenheit 451 does not read like a "novel of ideas," it is a novel in which diametrically opposed ideologies are developed and played out against each other in a complex, thoughtful way.
