Wanting to reboot the economy’s deterministic effect on the Marxist theory, Weber combined his interest in economy with sociology. He attempted to establish historical cause-effect relationship, through a historical study, not only depending on economy variables. One of his fundamental works, Die Protestantische Ethike und der Geist Kapitalismus (protestant ethic and the capitalism spirit) 1904-1905, attempting to demonstrate that Calvinistic religious and ethic values exerted great a influence on the development of capitalism. He returned to the same ideas when he studied the Asian religions and philosophies impetrating the oriental cultures, concluding that those were the causes for preventing the development of capitalism in those societies, in spite of existing favorable economic factors for the development of such capitalism. Max Weber is considered as one of the founders of modern sociology thinking. Perhaps, he is the most important sociologist of the XXth century, particularly known for his systematic approach to political sociology and the development of capitalism and bureaucracy. He explored the influence of ethical values and religion. His most renowned works were: Protestant ethics, The Spirit of Capitalism, Economy and Society, and The Politician and the Scientist.
