"[Voltaire] theoretically prefers a republic, but he knows its flaws: it permits factions which, if they do not bring on civil war, at least destroy national unity; it is suited only to small states protected by geographic situation, and as yet unspoiled and untorn with wealth; in general "men are rarely worthy to govern themselves." Republics are transient at best; they are the first form of society, arising from the union of families; the American Indians lived in tribal republics, and Africa is full of such democracies. but differentiation of economic status puts an end to these egalitarian governments; and differentiation is the inevitable accompaniment of development."
