The article explores psychological motives in Leopold Blaustein’s philosophy. Blaustein was educated in Lvov, Freiburg im Breisgau and Berlin. In his original explorations, he attempted to connect a phenomenological perspective with descriptive psychology. As trained by Twardowski, he took over some motives of understanding the method of philosophy (psychology), its objectives and aims. The author situates Blaustein also in a dialogue with Stumpf and next to the context of Dilthey’s humanistic psychology is examined. Finally, the article explores the influences of Gestalt psychology on Blaustein. The ultimate thesis of the article is that Blaustein’s method can be grasped as a phenomenologically oriented descriptive psychology.
