The article deals with statements that: (1) It is possible and appropriate to practice science that can be called 'history-sociology' justified by: a) constituting cognitive problems -common for both historians and sociologists; b) methods integrating cognitive acts of historians and sociologists; c) convergent scientific lexicons used by both historians and sociologists and becoming consolidated in the course of their work; (2) It is reasonable to read works of historians as sociological works and to read works of sociologists as historical works; (3) The fact that on the map of the social sciences exist (exclusively) various 'histories-sociologies' should be considered as one of the 'peculiarity of the social sciences'.
