This review is dedicated to one of the most provocative books recently appeared in Russian sociology - Theory of practices by Vadim Volkov and Oleg Kharkhordin. In his review (Practice of theories) Victor Vakhshtayn is trying to reconstruct main theoretical resources, key pre-theoretical metaphors and the very cognitive style of contemporary practice-oriented sociology. Vakhshtayn is broadening theoretical and philosophical context of latest sociological concepts, proliferating from the field of microsociology and philosophy of everyday life to moral philosophy and actual sociological theorizing.
