Abstract
In many respects, Mach’s arrival in Vienna in 1895 marks the beginning of a new era in Austrian philosophy, paving the way for young philosophers and scientists like Hahn and Neurath and preparing the soil for the Vienna Circle. While this understanding of Mach’s contribution to the development of Viennese philosophy seems correct to an important extent, it leaves aside the role of Brentano and his school in this development. I argue that the Brentanian and Machian moments of Austrian philosophy are jointed. I propose a description of the nature of these joints based on institutional, methodological, and philosophical aspects of these phases, and suggest a diagnosis that supports what I take to be the right carving between these two moments.
