I'm a big fan of dystopian novels and stories, so I'm really surprised I've never heard of this author nor his novel (which predates 1984 and Brave New World) called We:
As the novel opens, it's the 26th century A.D., and the Earth is under the power of the government of the dictator known as the Benefactor. A Two-Hundred-Years War has killed all but .02 percent of the world's population, giving rise to the One State, which was partly created out of the need to ensure that there could be no more revolutions. The One State has discovered the equation for "mathematically infallible happiness," which mostly consists of eliminating ego and desire. People no longer have names but numbers, and they're taught to think of themselves not as individuals, but as parts of a whole, a unified "we."
I'm going to have to get a copy of this.
