I'm reading Walden by Thoreau at the moment and it has made me think about the other utopia/dystopia books I have read. I have come to the conclusion that utopia is unobtainable and that that is probably a good thing because it would supress creativity and individuality. It really depends on what you want to achieve with utopia. If you want individuality and freedom to believe what you want then there will always be wars etc. If you are aiming for a society where society comes first and is more important than any one individual then peace could possibly be achieved.
