The chief qualification of a mass leader has become unending infallibility; he can never admit an error. The assumption of infallibility, moreover, is based not so much on superior intelligence as on the correct interpretation of the essentially reliable forces in history or nature, forces which neither defeat nor ruin can prove wrong because they are bound to assert themselves in the long run. Mass leaders in power have one concern which overrules all utilitarian considerations: to make their predictions come true.
Hannah Arendt
The Origins of Totalitarianism (1951)
