What is the theme of Fahrenheit 451?
Ray Bradbury himself said that this novel wasnt just 'about censorship' --- but various critics and scholars have differed about the main/central theme.
basically, the book shows or depicts a future American society where books are banned and any house containing them is burnt down. ostensibly, this does look like a form of (rather extreme) censorship of books. in addition, scholars opine that (a) the book is also a critique of other media such as TV, film etc, which is increasingly replacing books in modern American society, and indeed, making or turning books into 'oddities', even something threatening; and (b) it is also a view of how people (especially governments and people in power) react to dissenting views and ideas and try to destroy them, in any form or shape.
