It is the opinion and belief of the majority of the most ancient sages . . . that there will come a fated and predestined time when the earth will be completely leveled, united and equal, there will be but one mode of life and but one form of government among mankind who will all speak one language and will live happily. TRANSLATED FROM PLUTARCH, "ISIS AND OSIRIS," §47.
