The article is focused on the work of Professor B.G. Mogilnitsky, the renowned leader of Tomsk historiographical and methodological school. An heir and a successor of the best traditions of Russian Medieval studies represented by D.M. Petrushevsky, A.I. Neusykhin and A.I. Danilov, B.G. Mogilnitsky has created his own model of constructive critical analysis of historiography, which reveals the exceptional width of his cultural and intellectual horizons. His scholarly research and teaching have been so closely intertwined that the three-volume edition of his recent "History of historical thought" is widely regarded not only as a course of lectures, as it is stated in the subtitle, but as a major contribution to historiography in its own right.
