This article argues that the polemics accompanying the valuation of Islamist social movements occur because studies of political Islam are often oriented towards the debate over the relative worth of Western and Islamist routes to modernity and the civilizing process. The method pursued by Weber to delineate the Christian activism of The Protestant Ethic - minus its debilitating Eurocentrism - is suggested as a helpful model for analyzing the complexity of Islamist interventions. These theoretical remarks are grounded in a study (...) of the transformation of public space effected by the Turkish Islamist party Refah upon its winning the Greater Istanbul Municipality in the 1994 local elections. The construction of Islamist tea gardens/restaurants reveals the conflicting civilizing practices of Islamists themselves as well as the plurality of interests and ethical commitments seeking shelter under the universal ethic of the Islamic ümmet.
