From New Harmony to Ariadaeus Dome, utopias have been built on philosophical foundations by rational minds brandishing simple solutions to the eternal problems of human societies. The problem each has faced is that those eternal problems are the result of real people living in the real world and dealing with real circumstances.
Utopias fail not only because their philosophies are unrealistic or the rationality is unreasonable, but because they invariably deny the nature of the human material they have to work with. But we are human. Wherever we go, for good or ill, we take our humanity with us. How could it be otherwise?
