Essays on the Theory of Historical Science is a significant work by Russian-Bulgarian historian and philosopher Peter Bitsili (1879–1953), who explores methodology, the nature of historical knowledge, and the connection between the past and the present. Published in Bulgarian (e.g., 1994, trans. Stanislava Milanova), the book analyzes the historical process as a cultural phenomenon, criticizing positivism and seeking the meaning of historical events through a synthesis of cultural studies and sociology.
