«Questo è il vero fenomenalismo e prospettivismo, come lo intendo io», scrive Nietzsche in FW 354, chiudendo una lunga riflessione sul tema della coscienza e del bisogno di comunicazione dell’uomo. Mantenendo sullo sfondo le questioni più strettamente legate alla dimensione psicologica, vorrei partire da questa dichiarazione per considerare alcuni aspetti della teoria della conoscenza di Nietzsche ed intervenire in una nuova determinazione del suo carattere prospettico. In particolare, vorrei soffermarmi sul tema del gregge umano e della specie come reale soggetto della visione prospettica, per poi discutere il riferimento al fenomenalismo rintracciabile in alcuni appunti dedicati ad una declinazione del Wille zur Macht come conoscenza.

Friedrich Nietzsche’s criticism towards the substance-concept „I“ plays an important role in his late thought, and can be properly understood by making reference to the 19th century debate on the scientific psychology. Friedrich Lange and Ernst Mach gave an important contribution to that debate. Both of them developed the ideas of Gustav Fechner, and thought about a „psychology without soul“, i.e. an investigation that gives up with the old metaphysics of substance in dealing with the mind-body problem. In this paper I shall deal with both Lange and Mach (whose writings has been read by Nietzsche), in order to shed some light on Nietzsche’s rejection of the „I“ in philosophy.

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.

Friedrich Nietzsche's criticism towards the substance-concept «I» plays an important role in his late thought, and can be properly understood by making reference to the 19th century debate on the scientific psychology. Friedrich Lange and Ernst Mach gave an important contribution to that debate. Both of them developed the ideas of Gustav Fechner, and thought about a «psychology without a soul», i.e. an investigation that gives up with the old metaphysics of substance in dealing with the mind-body problem. In this paper I shall deal with Lange's and Mach's view of the I/soul, in order to shed some light on Nietzsche's rejection of the «I» in philosophy.
