was the modern society in which individualism and rationality had become more dominant. He also drew a sharp line between the realm of conceptuality and the reality of social action: the first must be treated axiomatically and in a deductive way ('pure' sociology), whereas the second empirically and in an inductive way ('applied' sociology). His ideas were further developed by Max Weber, another early German sociologist. Weber argued for the study of social action through interpretive (rather than purely empiricist) means, based on understanding the purpose and meaning that individuals attach to their own actions. Unlike Durkheim, he did not believe in monocausal explanations and rather proposed that for any outcome there can be multiple causes. Weber's main intellectual concern was understanding the processes of rationalisation, secularisation, and "disenchantment", which he associated with the rise of capitalism and modernity. Weber is also known for his thesis combining economic sociology and the sociology of religion, elaborated in his book The Protestant Ethic and the Spirit of Capitalism, in which he proposed that ascetic Protestantism was one of the major "elective affinities" associated with the rise in the Western world of market-driven capitalism and the rational-legal nation-state. He argued that it was in the basic tenets of Protestantism to boost capitalism. Thus, it can be said that the spirit of capitalism is inherent to Protestant religious values. Against Marx's historical materialism, Weber emphasised the importance of cultural influences embedded in religion as a means for understanding the genesis of capitalism. The Protestant Ethic formed the earliest part in Weber's broader investigations into world religion. In another major work, "Politics as a Vocation", Weber defined the state as an entity that successfully claims a "monopoly of the legitimate use of physical force within a given territory". He was also the first to categorise social authority into distinct forms, which he labelled as charismatic, traditional, and rational-legal. His analysis of bureaucracy emphasised that modern state institutions are increasingly based on rational-legal authority. Weber´s wife, Marianne Weber also became a sociologist in her own right writing about women´s issues. She wrote Wife and Mother in the Development of Law which was devoted to the analysis of the institution of marriage. Her conclusion was that marriage is "a complex and ongoing negotiation over power and intimacy, in which money, women's work, and sexuality are key issues". Another theme in her work was that women's work could
