The intellectual arguments used by the State throughout history to “engineer consent” by the public can be classified into two parts: (1) that rule by the existing government is inevitable, absolutely necessary, and far better than the indescribable evils that would ensue upon its downfall; and (2) that the State rulers are especially great, wise, and altruistic men — far greater, wiser, and better than their simple subjects. In former times, the latter argument took the form of rule by “divine right’ or by the “divine ruler” himself, or by an “aristocracy” of men. In modern times, as we indicated earlier, this argument stresses not so much divine approval as rule by a wise guild of “scientific experts” especially endowed in knowledge of statesmanship and the arcane facts of the world. The increasing use of scientific jargon, especially in the social sciences, has permitted intellectuals to weave apologia for State rule which rival the ancient priestcraft in obscurantism. For example, a thief who presumed to justify his theft by saying that he was really helping his victims by his spending, thus giving retail trade a needed boost, would be hooted down without delay. But when this same theory is clothed in Keynesian mathematical equations and impressive references to the “multiplier effect,” it carries far more conviction with a bamboozled public.
