The purpose of this article is to show the main trends in philosophy that influenced Władyslaw Tatarkiewicz’s science research, with special consideration of neo-Kantianism (the Marburg and the Baden Schools). Władysław Tatarkiewicz, one of the most significant polish historians of philosophy, rarely made comments on his preferred methods and on his concept of history of philosophy. Nevertheless, many of the methodological issues raised by Tatarkiewicz are focused on the problem of historical synthesis, at which the historian is obliged to make specific assessment concerning the subject matter of the research. Tatarkiewicz’s position on historiography indicates its relationship with remaining humanistic disciplines.
