A sort of advanced Earth, Utopia is some three thousand years ahead of humanity in its development. For the 200,000,000 Utopians who inhabit this world, the "Days of Confusion" are a distant period studied in history books, but their past resembles humanity's in its essentials, differing only in incidental details: their Christ, for example, died on the wheel, not on the cross. Utopia lacks any world government and functions as a successfully realised anarchy. "Our education is our government," a Utopian named Lion says. Sectarian religion, like politics, has died away, and advanced scientific research flourishes. Life in Utopia is governed by "the Five Principles of Liberty", which are privacy, free movement, unlimited knowledge, truthfulness and free discussion (allowing criticism).
