Talking Past Each Other: Mach and Husserl on Thought Economy

Abstract

This paper revisits the debate between Mach and Husserl on thought economy and argues that, to a considerable extent, they talked past each other, insofar as the latter rejected thought economy as a principle of theoretical rationality, whereas the former conceived of it as a principle of practical rationality. This is further supported by their correspondingly different readings of the so-called principle of the permanence of forms.
