The aim of the article is to present cognitive challenges in the area of management. Researchers and reflective managers still work on the identity of management belonging to the social sciences. The paper depicts the connections between cognitive problems (from the epistemological point of view), management methodology and social practice. Management sciences are parts of historical discourse and because of that epistemological and methodological levels have an impact on social practice. The main concern of this paper is the role of the management scientist, consultant and teacher. The analysis suggests that academic teacher and researcher are social roles with a character that can be called universal. Practitioner is associated rather with pragmatic aspect of management science. Practitioners are often regarded as managers, but their roles in the organisation might as well be non-managerial.
