ABSTRACT I have argued that Nietzsche was influenced by Afrikan Spir's falsification thesis, according to which all empirical judgments are false because they attempt to impose the necessity, unity, and timelessness of thought upon the contingency, plurality, and successiveness of sensations. My reading has been challenged by Nadeem Hussain, who claims that it ignores Spir's phenomenalism. For the phenomenalist, true judgments about sensations are possible. I argue here that Hussain reads Spir as a phenomenalist only because he (...) mistakenly concentrates on the first book of Spir's major work, Denken und Wirklichkeit, before Spir presented his argument for falsificationism. When the rest of Spir's work is considered, it is clear that Spir believes that even sensations cannot be thought without falsity. I end with a brief discussion of the consequences of my argument for understanding Nietzsche. (shrink)

A recepção de Nietzsche da filosofia transcendental de Kant é intermediada por diversos autores de diferentes tendências filosóficas que se viam em continuidade com o projeto kantiano de uma filosofia crítica. Um desses autores é Afrikan Spir, filósofo que levou a cabo um programa de renovação da filosofia crítica que ia na contramão da tendência hegemônica na segunda metade do século XIX de naturalização do kantismo. A influência de Spir na construção de algumas das teses epistemológicas centrais do (...) pensamento de Nietzsche é variada, assim como sua importância no que tange à recepção e à crítica nietzscheana ao idealismo transcendental. Nietzsche se apropriou e reinterpretou várias teses e temas presentes na reformulação da teoria kantiana do transcendental proposta por Spir. O objetivo do presente trabalho é investigar o alcance e a importância dessa apropriação e suas consequências para a crítica de Nietzsche ao transcendentalismo. Esta crítica é formulada a partir do pensamento do devir, que constitui a base do seu programa de uma filosofia histórica. Nietzsche's reception of Kant's transcendental philosophy is mediated by various authors from different philosophical tendencies who saw themselves in continuity with the kantian project of critical philosophy. One of these authors is Afrikan Spir, a philosopher who undertook a program of renovation of critical philosophy that went against the tendency of naturalization of kantianism which was hegemonic in the second half of the 19th century. Spir's influence on some of Nietzsche's central epistemological theses is variegated, as well as his importance concerning Nietzsche's reception and criticism of transcendental idealism. Nietzsche appropriated and reinterpreted many theses and themes that featured Spir's reformulation of Kant's theory of the transcendental. The objective of this paper is to investigate the reach and the importance of this appropriation and their consequences for Nietzsche's criticism of transcendentalism. This critique is formulated on the basis of the thought of becoming, which provides, on its part, the basis for his program of a historical philosophy. (shrink)
