Immanuel Wallerstein on the origins of sociology

“…the dominant liberal ideology of the nineteenth century . . . argued that state and market, politics and economics, were analytically separate. . . . Society was adjured to keep them separate, and scholars studied them separately. Since there seemed to be many realities that apparently were neither in the domain of the market, nor in that of the state, these realities were placed in a residual grab-bag which took as compensation the grand name of sociology. . . . Finally, since there were people beyond the realm of the civilized world, . . . the study of such peoples encompasses special rules and special training, which took on the somewhat polemical name of anthropology.”
