 Roughly put, taking place in all areas of human life from religion and law to music and architecture, rationalization means a historical drive towards a world in which “one can, in principle, master all things by calculation” [Weber 1919/1946, 139]. For instance, modern capitalism is a rational mode of economic life because it depends on a calculable process of production. This search for exact calculability underpins such institutional innovations as monetary accounting (especially double-entry bookkeeping), centralization of production control, separation of workers from the means of production, supply of formally free labour, disciplined control on the factory floor, and other features that make modern capitalism qualitatively different from all other modes of organizing economic life. The enhanced calculability of the production process is also buttressed by that in non-economic spheres such as law and administration. Legal formalism and bureaucratic management reinforce the elements of predictability in the sociopolitical environment that encumbers industrial capitalism by means of introducing formal equality of citizenship, a rule-bound legislation of legal norms, an autonomous judiciary, and a depoliticized professional bureaucracy. Further, all this calculability and predictability in political, social, and economic spheres was not possible without changes of values in ethics, religion, psychology, and culture. Institutional rationalization was, in other words, predicated upon the rise of a peculiarly rational type of personality, or a “person of vocation” (Berufsmensch) as outlined in the Protestant Ethic. The outcome of this complex interplay of ideas and interests was modern rational Western civilization with its enormous material and cultural capacity for relentless world-mastery.
