Ernst Mach’s definition of the relationship between thoughts and facts is well known, but the question of how Mach conceived of their actual relationship has received much less attention. This paper aims to address this gap in light of Mary B. Hesse’s view of a postempiricist approach to natural science. As this paper will show, this view is characterized by a constructivist conception of the relationship between theory and facts that seems to be consistent with Mach’s observations on scientific knowledge. The paper first explores Hesse’s account of postempiricism and her project of a new epistemology. It then considers Ernst Mach’s conception of facts as the middle term of a triad of concepts that includes thoughts and elements as extreme terms. Finally, the paper will offer concluding remarks on Mach’s contribution to the debate on scientific realism and his attempt to redefine the notions of correspondence and objectivity in science.

This paper is devoted to a comparison between Ernst Mach's and Friedrich Nietzsche's anti-metaphysical approach to scientific and philosophical concepts. By making reference to Mach’s early essay on the conservation of energy (Die Geschichte und die Wurzel des Satzes von der Erhaltung der Arbeit, 1872), I argue that Nietzsche shares with him the idea that the concepts we adopt are only useful fictions developed during the history of humankind and its culture. This idea is fundamental for the development of modern science, since Mach’s epistemology contributed to give up the mechanistic (Newtonian) view of physics.

No presente trabalho apresentamos e traduzimos o texto “O Perigo da confirmação não-empírica", de Carlo Rovelli, cosmólogo italiano, um dos proponentes da gravitação quântica em loop. Trata-se do texto apresentado por Rovelli em 2015 durante o chamado “Debate de Munich” sobre o problema da base empírica do método científico. Rovelli analisa – e se contrapõe – à proposta do filósofo da ciência Richard Dawid, que em String Theory and the Scientific Method, defende que teorias científicas podem ser avaliadas, aceitas e defendidas a partir de critérios não-empíricos. Rovelli, a despeito de concordar com Dawid quanto a importância histórica dos argumentos não-empíricos no desenvolvimento de teorias físicas, sustenta que a confirmação empírica deve permanecer sendo considerada indispensável para a prática científica e o sucesso cumulativo da ciência.

This paper has a twofold aim. On the one hand, it explores the extent to which Mach was inspired by Kant’s approach to philosophical inquiry and tried to further elaborate it through his historico-critical method for enlightening scientific knowledge claims. On the other hand, it argues that the focus on the situated character of these claims that is implied in Mach’s epistemology makes it possible to compare his view to recent attempts to defend a perspectival realist account of scientific knowledge, thus revealing the relevance of Mach’s own approach as a methodology in the philosophy of science.

Aim of this paper is to reflect on the anthropological ideal Nietzsche outlines in his late period. The way Nietzsche deals with concepts such as “German”, “(good) European”, and “free spirit” in the sections of Twilight of the Idols which deal with Goethe will be especially considered. Furthermore, I shall argue that Renaissance plays an important role in Nietzsche’s anthropological project, for it helps to define the spiritual strength which characterizes the health type of man to which Nietzsche destined his late philosophical wisdom and gay science.

The paper provides a thorough account of the relationship between Ernst Mach’s thought and that of an apparently more intellectually distant near-contemporary, Friedrich Nietzsche. The consistency of their views is in fact substantial, as I try to show within the paper. Despite their interests being different, both Mach and Nietzsche were concerned with the same issues about our intellectual relationship with the external world, dealing with the same questions and pursuing a common aim of eliminating worn-out philosophical conceptions. Moreover, it can be argued that both Mach and Nietzsche converged on what we now know as the problem of realism versus anti-realism in the philosophy of science, and that they both rejected ‘representational’ (realist) conceptions of science in favour of a certain sort of pragmatic anti-realism, whose focus was on the role science plays as a means of orientation.

This paper focuses on sections of Nietzsche's Twilight of the Idols that deal with Goethe, with the aim of reflecting on the anthropological ideal that Nietzsche outlines in his late period. I give particular attention to the way in which Nietzsche deals with concepts such as "German", "(good) European", and "free spirit", connecting them in a coherent picture. Finally, I argue that the Renaissance plays an important role in Nietzsche's anthropological project, for it helps to define the spiritual strength that characterizes the healthy type of man whom Nietzsche thought destined to realize his late philosophy.

At the beginning of the twentieth century, theorists developed approaches to Nietzsche’s philosophy that provided an alternative to the received view, some of them suggesting that his view of truth may be his most important and original contribution. It has further been argued that Vaihinger’s fictionalism is the paradigm within which Nietzsche’s view can be properly contextualized. As will be shown, this idea is both viable and fruitful for solving certain interpretive issues raised in recent Nietzsche scholarship.

During his late period, Nietzsche is particularly concerned with the value that mankind attributes to truth. In dealing with that topic, Nietzsche is not primarly interested in the metaphysical disputes on truth, but rather in the effects that the "will to truth" has on the human being. In fact, he argues that the "faith in a value as such of truth" influenced Western culture and started the anthropological degeneration of the human type that characterizes European morality. To call into question the value of truth is therefore necessary, if one wants to help mankind to find her way in the labyrinth of nihilism. In this new addition to Nietzsche scholarship, Gori explores the origin and aim of the philosopher's　late perspectival thought by merging the theoretical with the historical approach, with a special focus on the epistemological debate that influenced Nietzsche. As a result, the book provides a contextual reading of the issue that supports the idea that Nietzsche’s attitude in addressing the problem of truth is, in a broad sense, pragmatic.

The paper aims to investigate some aspects of Ernst Mach’s epistemology in the light of the problem of human orientation in relation to the world (Weltorientierung), which is a main topic of Western philosophy since Kant. As will be argued, Mach has been concerned with that problem, insofar as he developed an original pragmatist epistemology. In order to support my argument, I firstly investigate whether Mach defended a nominalist or a realist account of knowledge and compare his view to those elaborated by other pragmatist thinkers, such as W. James, H. Vaihinger and H. Poincaré. Secondly, the question of what does it mean, for Mach, to orient ourselves in science is addressed. Finally, it will be argued that, although Mach tried to keep his epistemology restricted to a mere operational and economical account of science, that question involves the wider plane of practical philosophy.

The paper explores the issue of moral relativism in Nietzsche, and tries to argue that Nietzsche's attitude towards moral values does not support a radical relativism according to which since (i) every moral interpretation is relative to a judging perspective, and (ii) an absolute viewpoint is lacking, then (iii) every moral interpretation seems to be as true, valid or justified as the others. On the contrary, Nietzsche's perspectivism leaves space for a rank order among values, whose establishment is considered by Nietzsche as the future task of the philosopher.

L'articolo si propone di accostarsi alla figura di Ernst Mach seguendo la stessa metodologia storico-critica da lui utilizzata. Essa permette di contestualizzarne la figura e l'opera in un momento significativo della storia della filosofia occidentale, ma anche di ridefinire alcuni concetti fondamentali del suo pensiero. Scopo ulteriore della ricerca è di osservare da una diversa prospettiva la questione relativa al valore filosofico del lavoro epistemologico di Mach, mostrando come esso possa essere affermato senza bisogno di uscire dai confini da lui stesso tracciati.

ITALIAN: Contrariamente a quanto possa suggerire una lettura superficiale, il prospettivismo di Nietzsche è limitato alla sfera teoretica solo in apparenza. Nietzsche, infatti, collega questa nozione alla propria analisi dei valori e, più in generale, alla critica della morale. Scopo del presente articolo è di presentare una disamina di quello che possiamo chiamare il "prospettivismo morale" di Nietzsche. Col preciso scopo di rispondere alla domanda relativa a quale tipo di filosofia pratica derivi dalle riflessioni di Nietzsche sul prospettivismo, concentreremo la nostra attenzione su due posizioni che erroneamente si crede possano seguire da esse: l'individualismo radicale e il relativismo forte. -/- ENGLISH: Contrary to what a superficial reading of Nietzsche might suggest, Nietzsche’s perspectivism is only apparently limited to the theoretical sphere. In fact, Nietzsche also relates perspectivism with his analysis of values and, more in general, with his critique of morality. The aim of the present paper is to present an overview of what might be called Nietzsche’s “moral perspectivism”. In order to answer the question about what kind of practical philosophy derives from Nietzsche’s perspectivism, we shall focus the attention on two views which are erroneously believed to follow from it: radical individualism and strong relativism.

The «good European» is a rich and important topic in Nietzsche’s philosophy. It is first related to Nietzsche’s early reflections on European culture. Then, during the 1880’s, it gains philosophical value, being strictly connected with the purposes of Nietzsche’s mature thought. The aim of this paper is to show that only with reference to these purposes has the notion of «good European» a political meaning, being the good Europeans primarily the leaders of the spiritual development that follows the overcoming of Christian morality. To this end, we shall track the genesis and development of the notion of «good European», from Human, all too Human I to Nietzsche’s writings from the years 1885-1887.

The paper addresses the issue of scientific realism in Mach, and his pragmatist approach to epistemology. Firstly, Eric Banks’s interpretation of Mach as a direct realist about particulars will be explored and discussed. Secondly, Sami Pihlström’s pragmatic realism will be considered, and it will be suggested that this view can be more viably attributed to Mach. Finally, in the light of Mach’s 1910 paper on Sensory Elements and Scientific Concepts, it will be argued that Mach’s agnosticism was probably stronger than any moderate form of realism he could have been committed to, and that he was a radical pragmatist in refusing to be concerned with any kind of metaphysical issue.

The paper defends the idea that Jamesian pragmatism, Nietzschean perspectivism, and philosophical anthropology represent a consistent triad, for the similarities and connections between the first two positions rest in their engagement with the anthropological question. As will be argued, a) pragmatism is concerned with anthropology and that it deals with a fundamental issue of Nietzsche’s late thought; b) the problem of the type of man (der Typus Mensch) is involved in Nietzsche’s questioning the value of truth, and perspectivism is an alternative view to Platonic and Christian metaphysics which arises from the same phenomenalist conception of knowledge defended by James ; c) Nietzsche’s interest in developing a philosophy that affirms the perspectival character of existence is primarily anthropological, and this is in fact the pragmatic criterion of validity that one can attribute to Nietzschean perspectivism.

La noción de perspectivismo, presente en la producción tardía de Nietzsche, delimita un ámbito particularmente interesante y fértil. En efecto, esta metáfora visual, que el filósofo utiliza antes que nada en referencia a la dimensión epistémica, encierra profundas consecuencias hermenéuticas y prácticas. Los ensayos de este volumen dan cuenta de esta doble implicancia. El primero, poniendo la investigación filológica al servicio de la reflexión filosófica, propone una discusión contextual de la dicotomía "hechos-interpretaciones", estrechamente ligada al perspectivismo nietzscheano. El segundo lleva la atención del plano teórico al plano práctico y se concentra en el tema de la moral gregaria, que en el quinto libro de la "Ciencia jovial" Nietzsche presenta unido indisolublemente al perspectivismo y al fenomenalismo de la conciencia. Estas incursiones en el pensamiento de Nietzsche y en sus lecturas permiten antes que nada volver a considerar algunas célebres cuestiones de su reflexión madura y tomar nota de la riqueza de su pensamiento, en contraste con las malas interpretaciones que han visto en su perspectivismo la expresión de un mero relativismo y un nihilismo epistemológicos.

Il presente contributo muove dalle osservazioni sul linguaggio che Nietzsche svolge in Umano, troppo umano, I, § 11, con lo scopo di riflettere sulla posizione anti-realista che Nietzsche sostiene in quell’aforisma e di evidenziare il ruolo che essa svolge nelle sue più tarde considerazioni relative alla cultura occidentale e alla sua antropologia. Come si avrà modo di mostrare, la critica nietzscheana al realismo del senso comune è in linea con alcune epistemologie pragmatiste sorte tra Otto- e Novecento. Questo elemento di “attualità” non mina però l’originalità della riflessione di Nietzsche su quell’argomento. Piuttosto, è possibile sostenere che l’idea che il pensiero filosofico intervenga in una correzione dell’impegno metafisico proprio del senso comune sia lo strumento teoretico che permette a Nietzsche di operare sullo sviluppo della cultura e società europee.

The paper explores Nietzsche's observations on language in Human, All Too Human I, 11; reflects on the anti-realist position that Nietzsche defends in that aphorism; and focuses on the role she plays in his later investigation on Western culture and its anthropology. As will be argued, Nietzsche's criticism towards common sense realism is consistent with some pragmatist epistemologies developed during the late-nineteenth and early-twentieth century. This treat of " timeliness " does not limit Nietzsche's originality on the topic. In fact, the idea that philosophy can contrast the metaphysical commitment of common sense can be seen as the theoretical tool that allows Nietzsche to operate on the development of European culture and society.

The paper explores the few occurrences of the expression «will to nothingness» (Wille zum Nichts) in Nietzsche’s writings, and its relationship with the notions of ‘will to truth’ and ‘ascetic ideal’. Aim of this research is to show that these notions are mutually related, and that they outline the objectives of Nietzsche’s late thought. The investigation will focus in particular on the concept of “realism” that appears in Nietzsche’s late writings, and that can be interpreted as an existential attitude towards life that contrasts pessimistic nihilism.

L’analisi dei principali temi della filosofia di Nietzsche conduce all’individuazione della nozione di forza come elemento centrale delle sue riflessioni. Egli la incorpora ed utilizza filosoficamente, in periodi diversi, per la definizione di teorie centrali quali l’eterno ritorno, la volontà di potenza e il prospettivismo conoscitivo. L’assimilazione di questa nozione – come è stato osservato in passato – può essere riportata alla sua lettura nel 1873 della Theoria philosophiae naturalis del matematico Ruggero Boscovich. Attraverso una dettagliata analisi del materiale postumo oltre che del contesto delle discussioni scientifiche dell’epoca, questo studio si propone di chiarire nella maniera più esaustiva fino a che punto il sistema di Boscovich e, più in generale, la visione dinamica del mondo in esso delineata abbiano influito sul pensiero nietzscheano, con la precisa finalità di restituire nella sua complessità il rapporto di Nietzsche con questa figura.

Friedrich Nietzsche’s criticism towards the substance-concept “I” plays an important role in his 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 thought about a “psychology without soul”, that is, 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 views, in order to shed some light on Nietzsche’s rejection of the I in philosophy.

During his late period, Nietzsche focused on the problem of the “value of truth”, since according to him it plays an important role on Western culture and its anthropology. That reflection had been influenced by some outcomes of the late-nineteenth century scientific research, and can be therefore compared with other strategies that, during those years, faced the relativism implied in modern epistemology, e.g. William James’s Pragmatism. This paper aims to explore the pragmatic feature of Nietzsche’s investigation on truth. As will be shown, Nietzsche’s perspectival thought can indeed be compared with classic Pragmatism on several aspects, e.g. the cultural context out of which both these philosophical position arised, and the broad consequences of their impact on European culture.

Hans Kleinpeter provided a popularization of both Ernst Mach's thought and the scientific philosophy that forerun the foundation of the Vienna Circle. Between 1912 and 1913 Kleinpeter published the articles that one finds here in their first Italian translation; they concern a comparison between Mach's epistemology and Nietzsche's thought, and are thus an original contribution to the reception of the latter's philosophy. In these texts Kleinpeter anticipates some of the ideas he later presented in his work devoted to the 'Phenomenalistic' worldview, whose - according to him - Nietzsche has been one of the main upholders, as much as Mach.

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.

«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.
