“There are no kings inside the Gates of Eden” sang Bob Dylan back in1967, at the height of that decade’s idealism and optimism. In an ideal world there would be no need for kings or rulers of any kind. People would cooperate, not compete; they would be ruled by wisdom and reason, live together in peace and love, and the divisions and prejudices of race and nation, religion and class would be no more. Eden is the best of all possible worlds, except that it is, in all probability, impossible.
