Max Weber
German sociologist, political economist and historian (1864–1920), born in Erfurt, professor at Freiburg and Heidelberg until a severe nervous breakdown kept him away from teaching for years, and, together with Durkheim and Marx, one of the three great founders of modern sociology. His most famous work, The Protestant Ethic and the Spirit of Capitalism (1904–05), advances a provocative thesis: Calvinism's ascetic ethic —with its doctrine of predestination, which generated existential anxiety over one's own state of salvation, and its valuation of methodical labour, thrift and economic success as possible 'signs' (never proofs) of being among the elect— unintentionally created the psychological and cultural ethos necessary for the development of modern rational capitalism, a paradigmatic example of how religious ideas can produce unintended social and economic consequences. He developed the central concept of rationalisation: the historical process by which Western social life became progressively organised according to criteria of calculation, efficiency and predictability, leaving behind tradition, magic and charisma —a process he himself viewed with growing pessimism, fearing its capacity to trap the modern individual in a bureaucratic 'iron cage' devoid of ultimate meaning. He also formulated the influential typology of three types of legitimate authority —traditional, charismatic and legal-rational—, introduced the key methodological concept of the ideal type as a heuristic tool for comparison, and argued, with methodological rigour, in Science as a Vocation and Politics as a Vocation, for the necessity of a 'value-free' sociology that would understand the subjective meaning of social action without presuming to judge it morally, thereby founding interpretive sociology (Verstehen) as a distinctive method of the social sciences.
