I read this a few
This book preceded and heavily influenced both 1984 and Brave New World. People have no names, just letters and numbers. They plan on going on to other planets to compel others to adopt their mathematically-minded happiness. Emotions aren't allowed. They live in glass apartments. Everything 'human' is discouraged. But. . . a rebel faction is present in and outside 'the wall.' Will those inside the wall learn to be truly human?
Side note: A few weeks ago I saw the movie Equilibrium starring Christian Bale, and it surely had to be influenced by this novel. If you're interested in the dystopian genre, it's a must-see. See my review here.
