Stumpf’s doctrine of the categories is of great importance for our understanding of his philosophy. This theme had been widely discussed among German thinkers after Kant; Brentano himself had repeatedly dealt with it since his early works. However, Stumpf considerably diverges from Brentano on this crucial philosophical topic. Although a systematic discussion can be found only in Stumpf’s posthumous Erkenntnislehre, his core ideas on the categories can be traced to his early work on space of 1873. In fact, Stumpf claims that the peculiar relationship between extension and color is analogous to the relationship that holds between substance and accidents. Thus, like any other category, substance empirically stems from perception. Sensory experience, for Stumpf, is made up of perceptual wholes, whose attributes are typically bound to each other, rather than separately given in bundles, as Hume and other associationists used to assume. Thus, the achievements of Stumpf’s holist psychology effectively contributes a solution to this classic metaphysical problem.

Together with other influential psychologists of the time, Wundt considers internal data as absolute evidence, grounding psychology on this assumption. In opposition to his former mentor, Külpe aims at rehabilitating Kant’s transcendental aesthetics. Yet, he is far from embracing transcendentalism and rejects Kant’s skepticism as to the possibility of a scientific psychology. Nevertheless, Külpe believes that Kant is right in considering internal data as unreliable for scientific purposes: accordingly, psychology should share the same scientific methodology of any other science.

Il lavoro analizza la tempestiva ricezione da parte di Cornelio Fabro della filosofia di Carl Stumpf, così come esposta nella postuma Erkenntnislehre. Fin dai lavori dei primi anni Quaranta Fabro adotta una concezione della ‘fenomenologia’ distante da quella di Husserl perché ricalcata sulla definizione stumpfiana. Più in generale, Fabro si ispira a Stumpf ancor più che allo stesso Brentano. A partire dalla distinzione tra ‘fenomeni' e ‘funzioni psichiche’ Stumpf è infatti capace di proseguire il rilancio dell’aristotelismo con coerenza ancor maggiore del maestro, all’insegna di un pieno riconoscimento del significato conoscitivo della percezione contro gli tipici di eccessi di ogni forma di intellettualismo.

The paper compares the ideas developed by Bozzi and Stumpf with regard to unity, identity, and causality. Although Bozzi’s formulation is independent from the one made by Stumpf in his Erkenntnislehre, these two positions share the same innovative importance granted to perceptual experience and to the problem of the origin of categories. Thus, despite different levels of awareness and formalization, in both authors we see the features of what we can call – analogous- ly to Bozzi’s naïve physics – a “naïve metaphysics”, at whose core lie the refusal of intellectualism, and the determination of the origin of categories in the concrete stream of perception.

Allievo di Brentano e Lotze, maestro di Husserl e Halle e dei Gestaltisti a Berlino dove fu voluto da Dilthey, Carl Stumpf fu per oltre mezzo secolo un protagonista della filosofia accademica tedesca. Ciò nonostante, il suo ruolo nella storia della filosofia tra Ottocento e Novecento è ancora sottovalutato dalla critica. Il saggio ricostruisce le linee generali del pensiero di Stumpf sottolinenandone il costante impegno in favore di una «Rinascita della filosofia» – come recita il titolo della sua prolusione rettorale del 1907, che può avvenire solamente grazie alla proficua ma critica interazione con le scienze naturali. In ciò Stumpf sviluppa originalmente il pensiero di Brentano ma in una direzione diversa da quella di Husserl, Marty o Meinong.

Il volume presenta una storia della filosofia della musica. A partire dalle idee sulla musica dei filosofi antichi, attraverso le concezioni medievali e rinascimentali, il volume considera l'impatto della rivoluzione scientifica, la stagione illuminista e gli sviluppi ottocenteschi, per giungere infine al ricco dibattito contemporaneo. Tra i principali autori trattati: i pitagorici, Platone, Aristotele, Aristosseno, Boezio, Agostino, Tomaso d'Aquino, Ficino, Galileo, Mersenne, Cartesio, Leibniz, Rousseau, Kant, Novalis, Schelling, Wackenroder, Hoffmann, Schopenhauer, Kierkegaard, Hegel, Hanslick, Helmholtz, Nietzsche, Bloch, Adorno, Jankélévitch, Wittgenstein, Langer, Kivy, Levinson, Scruton.

L’opera filosofica di Novalis, inedita e frammentaria per ragioni biografiche, è stata a lungo trascurata. Gli studi fichtiani e l’interesse per la scienza sono alla base della sua «Enciclopedistica», nella quale la filosofia della musica ha un posto rilevante. Novalis conosce la scienza acustica del suo tempo e riconduce i rapporti tra suoni e figure a una forza formatrice presente nella natura fin dal livello inorganico. La medesima forza si presenta poi nell’uomo tramite la voce, espressione più autentica della libertà assoluta dell’Io. Lungi da ogni «sentimentalismo» l’identità di uomo e natura si manifesta in una rarefatta estetica simbolica condensata da Novalis nell’immagine dell’«arpa eolia».

Music represents a crucial issue in nineteenth-century philosophy and science. Scholars generally possessed a good musical competence and contributed to the explanation of sound perception and aesthetic enjoyment in music. Reflexions on musical psychology, in turn, influenced general theories of mind, sometimes in an impressive way. Meinong plays a remarkable role within this context. Together with Mach, Ehrenfels and Stumpf, Meinong contributed to overtake Helmholtz ’ physical-physiological theory, supporting a more comprehensive approach. He was repeatedly concerned with problems such as to- nal fusion, tone quality and melodic perception. Although Meinong did not develop musical problems systematically, he assumed a quite original and interesting position. His ideas have been developed by some of his followers in the School of Graz.

This essay is about the Wolfgang Köhler’s philosophical ideas expressed in his The Place of Value in a World of Facts of 1938. Köhler, who strongly supports a scientific world view, considers the question as to whether science is able to cope with human values, besides natural facts. Relying upon phenomenological analyses, and on his previous researches in natural philosophy, Köhler introduces his doctrine of “epistemological dualism”. From a historical point of view, this theory exhibits some similarity with the philosophical ideas expressed by Köhler’s Berlin mentor Carl Stumpf. It is argued that Köhler’s epistemological dualism actually supports ontological monism and aims at offering a unified view of natural facts and human values.

Peirce’ s intellectual debt to Kant’ s transcendentalism has been long recognized. In this essay I investigate Kant’ s thoughts on “what is pragmatic” as a source of inspiration for him. Peirce was well acquainted with this often neglected facet of Kant’ s philosophy, that influenced both the core idea and the lexical coinage of his pragmatism. Both thinkers drew attention to the consequences of cognition for human actions. Pointing at the definition of the meaning of a defined notion, however, Peirce narrows remarkably the domain of Kant’ s “pragmatic horizon”. Accordingly, Kant cannot be truly considered a forerunner of Peirce’ s pragmatism.

This essay addresses the interrelations between philosophy and experimental sciences that lie at the heart of Carl Stumpf’s epistemology. Following a biographical exposé demonstrating how Stumpf succeeded in acquiring a dual competence in both philosophical and scientific fields, we examine the vast array of academic disciplines encompassed by his research. Such a biographical treatment aims, indeed, to better promote the thrust of Stumpf’s assertion that philosophical enquiries should always be carried out in close connection with scientific practices, and underlines how philosophico-scientific interactions established his work as a central pillar in the history of late nineteenth- and early twentieth-century German thought.
