For a time this protest found expression only in critical work. The picture of an economic order as a self-regulating mechanism, peopled with folk who could not but serve the community in serving themselves became very unreal. The complexity of industrialism made it hard to believe that the individual had knowledge enough to choose best for himself. The suspicion that frequently thought follows action made it hard to continue to believe in man’s complete rationality. The idea that incomes are different because opportunities are different led to a questioning of the justice of the ratings of men in the market. The unequal division of income made impossible pecuniary calculations in which each man counted for one and only for one. With these assumptions of 19th-century economics passed “the economic man,” “the Crusoe economy,” and the last of the divine theories, that of “enlightened self-interest.” It was no longer possible to build a defence of the existing order upon “the hedonistic conception of man” as “a lightning calculator of pleasures and pains, who oscillates like a homogeneous globule of desire of happiness under the impulse of stimuli that shift him about the area, but leave him inert.” The most immediate effect of this criticism was a change in method. The older process of juggling economic laws out of assumptions about human nature, human motives, and the beneficence of competition lost prestige. It was evident that if the system was to be appraised the facts must be had. Accordingly a veritable multitude of facts, good, bad, and mostly indifferent were treasured up. This process of garnering information soon made it evident that the facts about the relationship of industry to the welfare of the community were too varied and too numerous to be separately catalogued. Since only totals could be used, economics came to rely upon facts presented in the quantitative language of statistics.
