 Gottlob Frege was critical of "Philosophy of Arithmetic", and accused Husserl of relying too much on the metaphysical and not enough on the logical aspects of mathematics.Frege’s criticisms influenced negatively the young mathematician’s career as a professor.Husserl’s "Logical Investigations" secured his reputation ten years later, but Frege and others never accepted Husserl as a practitioner of true logic.
