This paper argues that frege did not significantly influence husserl's departure from psychologism by (1) examining husserl's early logical reflections, Especially those concerning the meaning of the term ""vorstellung"," and (2) determining which parts of husserl's "philosophy of arithmetic", Criticized for its psychologism by frege, Were psychologistic and when husserl rejected them. It concludes that the logical writings show an independent movement toward a non-Psychologistic position and that the psychologism of "philosophy of arithmetic" was abandoned by 1891 apart from any (...) fregean influence.

The article examines the development of Husserl’s early philosophy from his Habilitationsschrift to the Philosophie der Arithmetik . An attempt will be made at reconstructing the lost Habilitationsschrift . The examined sources show that the original version of the Habilitationsschrift was by far broader than the printed version, and included most topics of the PA. The article contains an extensive and detailed comparison of these texts to illustrate the changes in Husserl’s position before and after February 1890. This date is (...) taken as a turning point in his development, because of Husserl’s announcement in a letter to Carl Stumpf that he was mistaken in his basic assumption, i.e. that the analysis of the concept of Anzahl would yield a foundation for arithmetic. Some interesting conclusions in this respect can also be drawn from an unpublished lecture that Husserl held in the WS 1889/90, in which he anticipates aspects of his position hitherto deemed to belong to the last phases of the PA.
