““...there's no task more difficult than duping a sincere, honest man if he has the least bit of intelligence and life experience. Reasonably intelligent individuals are never hoodwinked individually. But they possess another, equally harmful form of this human frailty: they are subject to mass delusion. A swindler will never be able to lead a single individual by the nose; but as for a large group taken together, their noses are always ready and willing! Meanwhile, the swindlers, weak as individuals and each led by his own nose, when taken together can never be led by their noses. That's the whole secret of world history.””
