ABSTRACT
Introduction Husserl’s earliest philosophical work, his Hahilitationsschrift entitled On the Concept of Number. Psychological Analyses,1 appeared as a booklet in 1887; and four years later he published the first (and, as it turned out, the only) volume of an exhaustive study on the same topic entitled Philosophy of Arithmetic. Psychological and Logical Investigations.2 Of these two works we need here consider only the latter, however, for it in fact incorporates, ‘virtually verbatim’ (p. 8),3 almost all of the earlier study.
