Basing on A.S. Lappo-Danilevskiy manuscript “Scientific bases of sociology in their historical development” (1911) an analysis is made of the views of this academic on materialistic current in sociology – that of Marxist sociology. Lappo viewed Marxism as a kind of ‘nomothetic approach’ in social sciences assuming that historical materialism in its dogmatic version had exhausted its capabilities. A perspective for this current he saw in transformation of materialistic approach on the basis of recognizing the role of ideas in history, of psychological and epistemological analysis.
