Three titles. Brave New World, Nineteen Eighty-Four, Farenheit 451. Although the stories are far fetched, they are good reasons to keep your government in check never allow anyone to take your civil liberties away. The spirit of a free society will never be crushed, unless they get lazy and slowly allow their freedom to be eroded. I highly suggest these titles to anyone who didn't have them as required reading in school. There are other titles along the same path as these, feel free to mention them.
