ABSTRACT
The Philosophy of Arithmetic treats of the main psycho-logical questions connected with the analysis of the concepts of plurality, unity, and number, in so far as they are given to us really and not through indirect symbolization. The Philosophy of Arithmetic presents materials which have proved to be of real importance, and which indicate the promise of the author as an original investigator. The Philosophy of Arithmetic is a characteristic and important work in a number of respects. The close student of phenomenology is sure to find the Philosophy of Arithmetic revealing and helpful in the understanding of the motives that have always been effective in Husserl's thought. Quoting Weierstrass to the effect that pure arithmetic requires no presuppositions for its basis apart from the concept of number, Husserl tentatively accepts the view that the concept of a cardinal number is fundamental and begins with an analysis of the concept of number.
