Abstract
Ernst Mach was already an international successful experimental physicist and scientist, when he, after professorships for Mathematics and Physics in Graz and Experimental Physics in Prague, took over the chair for “Philosophy, particularly for the History and Theory of the Inductive Sciences”, at the University of Vienna in 1895. This turn from the natural sciences to philosophy was really an exception in the academic field.Given his strong as well as controversial history of influence in philosophy and in the sciences Mach’s own pessimistic statement about the emergence of aprioristic currents at the beginning of the twentieth century is surprising and in need of an explanation.The article deals with Mach’s appointment in Vienna and Mach’s autobiographical fragments on his relation to academic philosophy from a today’s point of view. It appears that Mach can be regarded as a pioneer and predecessor of a topical “historical epistemology”, “history and philosophy of science”, and above all as a theorist and practitioner of inter- and transdisciplinarity. If he is to be regarded a philosopher, it is mainly in the context of naturalism, pragmatism and common sense philosophy – as general theory of research.
