As in the Middle Ages in the West, so in Tokugawa Japan (1600–1868) men were fond of explaining the hierarchical society in which they lived by comparing it to an organism. Social classes, Confucian scholars said, were like parts of the body: each had a vital function to perform, but their functions were essentially different and unequal in value. In this scheme the peasants were second in importance only to the ruling military class. Just as the samurai officials were the brains that guided other organs, so the peasants were the feet that held the social body erect. They were the “basis of the country,” the valued producers whose labor sustained all else. But, as a class, they tended innately to backsliding and extravagance. Left alone they would consume more than their share of the social income, ape the manners and tastes of their betters, and even encroach upon the functions of other classes to the perilous neglect of their own. Only the lash of necessity and the sharp eye of the official could hold them to their disagreeable role. They had to be bound to the land; social distinctions had to be thrown up around them like so many physical barriers; and, to remove all temptation to indolence and luxury, they had to be left only enough of what they produced to let them continue producing.
