Just finished Fahrenheit 451 by Ray Bradbury. It's a very powerful book and to me anyway one that makes me a bit uneasy.
It was written in 1953 but points to me that stood out were the influence of television and the desire by the authorities to enforce equality; not to let people have the chance of equality, but to have the state enforce equality. Also the drive to get children into nursery asap and get everyone think the "right way". It is set in an America of the future where knowledge is frowned upon, books are burned, history has been re-written, questions are discouraged and spies are everywhere.
It's a book that probably needs to be re-read, so I will.
