In this paper I discuss the role played by Ernst Mach on Nietzsche’s thought. Starting from the contents of his Beiträge zur Analyse der Empfindungen, I’ll show the close similarities between their view on both human knowledge and the scientific world description. In his writing on science Nietzsche shares Mach’s critique to the 19th century mechanism and its metaphysical ground, as much as his way of defining the substantial notions such as matter, ego and free will. Moreover, my investigation will make it clear that Mach cannot be seen as a direct source of Nietzsche’s thought, since the latter wrote many times on the same subjects long before his first reading one of his works. Rather, it is possible to consider the writings of Lange, Spir and Spencer as the first sources of Nietzsche’s views on the main themes Mach dealt with in his work from 1886.

During the second decade of the 20th century Hans Kleinpeter, an Austrian scholar devoted to the development of the modern science, published some brief papers on Nietzsche’s thought. Kleinpeter has been one of the main upholders of Mach’s epistemology and probably the first who connected his ideas with the philosophy of Nietzsche. In his book on Der Phänomenalismus (1913) he described a new world view that arose in the 19th century, a perspective that ‒ according to him ‒ completely contrasted the mechanistic and metaphysical world view of the old school of scientific inquiry. The main outcome of the scientists whose name was related with this perspective (e.g. Clifford, Maxwell, Kirchoff and, obviously, Mach himself) has been the refusal of the absolute value of any “truth”. Kleinpeter’s statements on this topic are a good example of the rising of a Scientific Philosophy, whose development involved many scientists and thinkers that later set up the Verein Ernst Mach and the Wiener Kreis. On the other hand, his interest on Nietzsche is a relevant case of reception of the latter’s thought, that Kleinpeter puts into the context of the contemporary epistemology. In fact, he considers Nietzsche as one of the main upholders of the phenomenalistic world view, and states that he «took part at the same renewal of philosophical investigation that arose from the latest results of scientific inquiry» during the 19th century. A renewal whose main outcomes has been presented by John Stallo in his book on The Concepts and Theories of Modern Physics (1881), which Kleinpeter translated in German and published in 1901. According to Kleinpeter, in Nietzsche’s writings (mostly unpublished) one can find a theory of knowledge quite close to the one presented by both Mach and the new born Pragmatism, i.e. the complete refusal of an absolute truth and, therefore, the development of an antimetaphysical world view. In my paper I’ll discuss the main statements presented by Kleinpeter on this topic and show which of Nietzsche’s ideas has actually been in compliance with the main outcomes of late 19th century science. Thus, I’ll carry out a reconstruction of an unfamiliar side of the first period of reception of the philosophy of Nietzsche and its relevance to the development of a new (scientific) world view.

A full appreciation for Ernst Mach's doctrine of the economy of thought must take account of his direct realism about particulars (elements) and his anti-realism about space-time laws as economical constructions. After a review of thought economy, its critics and some contemporary forms, the paper turns to the philosophical roots of Mach's doctrine. Mach claimed that the simplest, most parsimonious theories economized memory and effort by using abstract concepts and laws instead of attending to the details of each individual event or experiment. For Mach, the individual case never truly repeated in all of its uniqueness, nor was all of the individual detail of a physical element adequately captured in abstract laws and schemata, however necessary these were for the pursuit of science. As can be shown from specific passages, some already published, some not, Mach's elements included physical qualia in nature similar to Russell's unsensed sensibilia, which existed even where there were no conscious observers. An argument will be presented to make the case that Mach believed in the mind-independent elements from the 1870s on, while other aspects of his thought evolved over time; I have thus dated the references to reflect this historical progression. I concentrate on Mach's ontology, as it bears on economy of thought, not his epistemology per se, which might well have been restricted to observable elements/sensations. After his own conversion to neutral monism, in the 1920s, Bertrand Russell echoed Mach's call for a 'future science' capable of handling the 'intrinsic character' of qualitative data directly without the excessive abstraction of physics.
