Note on Stumpf’s History of Active Intellection

Carl Stumpf, in his Spinozastudien, presents the Aristotelico-Scholastic thesis of the “parallelism” between mental acts and contents, i.e., the thesis that “the essential differences and divisions of the acts run in parallel to those of the contents, since they are determined in their specificity by the latter.” In his paper, Stumpf also distinguishes between passive and active accounts of intellection in the history of philosophy. Now, Stumpf, in his own theory of intentionality, has rather an active account of intellection: he holds that the contents of abstract presentations and judgments are “products” of these acts. Stumpf does not explicitly give a historical precedent for his position. In this note, I would like to discuss Stumpf’s historical narrative concerning the active accounts of intellection, as well as to complete this narrative with information about some prior philosophical positions resembling Stumpf’s own views on psychic products.
