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.

La percezione musicale ha avuto un ruolo significativo nella storia della psicologia della Gestalt. Muovendo dalle critiche di Mach ed Ehrenfels alla dottrina elaborata da Helmholtz e dall’elaborazione teorica di Stumpf, destinata a fungere da ponte concettuale, il lavoro analizza la riflessione svoltasi in seno alla psicologia della Gestalt. Sorprendentemente, Köhler non si concentra sulle Gestalten musicali complesse, ma sulle qualità tonali più elementari, mostrandone la totale irriducibilità a fattori fisico-fisiologici. Sulla stessa linea è anche Hornbostel, il quale amplia tuttavia il discorso mediante il richiamo al complesso antropologico dei vissuti umani, musicali ed extramusicali, che rimandano a un determinato contesto culturale, saldando così il nesso tra psicologia della Gestalt e ricerca nel campo etnomusicologico.

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.

In his first two Critiques, Kant makes a distinction between the empirical and the intelligible character. Yet, in his Pragmatic anthropology Kant adds the human beings’ “natural aptitude” to the customary dichotomy of “way of sensing” and “way of thinking”. In this paper, I investigate Kant’s concept of natural aptitude in his Pragmatic anthropology and in his Lectures on anthropology. Most probably, Kant’s sources lie in the Scholastic doctrine of the “character of scholars”. The “good mind” that Kant associates with the human beings’ natural aptitude – in sharp contrast with the autonomy implied by moral character – nevertheless reveals its significance in compensating for the human species’ “pragmatic predisposition”. To some extent, then, natural aptitude contributes to the pursuit of nature’s providential goals.

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.

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.

Ehrenfels, Höfler and Witasek competently contributed to a musical aesthetics based upon the principles of the Graz school. In spite of a shared general psychological framework, they deeply differ in applying it to the aesthetics of music. A double tendency can be pointed out. Ehrenfels and Höfler enthusiastically supported Richard Wagner and vindicated the aesthetic value of his music. Accordingly, they made large use of analogies between musical and organic Gestalten. In a platonic vein, Höfler also thinks of melodies as timeless objects, which are discovered rather than created by great artists. On the contrary, Witasek’s approach is quite rationalistic. Avoiding any intrusion of metaphysics, he describes the intellectual and emotional processes involved in hearing a piece of music. Wholly independently of Wagnerism, Witasek explains the complexity of musical experience in the general terms of Meinongian psychology.

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.

Many nineteenth-century psychologists assume that the measurement of psychic intensity is a prerequisite to the development of a truly scientific psychology. In the first edition of the Psychology from an empirical point of view, Brentano deals with this question. He assumes that all psychic phenomena admit of a certain intensity. Later on, Brentano retreats this doctrine and claims that only sensible phenomena admit of an intensity, whereas intellectual presentations do not. As a consequence, Brentano introduces a radical gap between sensible and noetic consciousness. By contrast, Stumpf maintains a continuity between sensations and presentations. The main difference between them is the degree of their intensity. The essay provides a discussion and a comparison of the above mentioned points of view.

The purpose of this book is to highlight Carl Stumpf's contributions to philosophy and to assess some of the aspects of his work. This book brings together several specialists of Stumpf and the school of Franz Brentano, and includes fourteen original studies (in English and German) on the various aspects of Stumpf's philosophy, and some of his unpublished writings. This book is divided into four sections, and also includes a general introduction on the reception and actuality of Stumpf's philosophy. The first section examines the historical sources of his philosophy, the second examines some of the central themes of his work and the third examines his relationship to other philosophers. The fourth section consists of notes taken by Husserl during Stumpf's lectures on metaphysics in Halle, Stumpf's introduction to the edition of his correspondence with Brentano, which he prepared in 1929, and some important letters pertaining to this correspondence. This book also provides a comprehensive bibliography of Stumpf's works.

Formatosi alla lezione di Franz Brentano e di Hermann Lotze, maestro a Halle di Edmund Husserl e in seguito, a Berlino, dei fondatori della psicologia della Gestalt – Köhler, Koffka e Wertheimer – Carl Stumpf fu uno dei massimi esponenti della filosofia del suo tempo. Filosofo dai vasti interessi, ma anche psicologo di rango, attento studioso di filosofia della musica e pioniere dell’etnomusicologia, Stumpf è una figura indubbiamente originale, il cui lungo itinerario intellettuale appare sempre più imprescindibile per comprendere l’evoluzione del pensiero filosofico della seconda metà dell’Ottocento e del primo Novecento in Germania. Estraneo ai dogmi del positivismo allora imperante, ma anche alla fascinazione trascendentale della fenomenologia husserliana, Stumpf concepisce la riflessione filosofica come esercizio critico aperto all’esperienza e tuttavia capace di trascenderla per mirare alle vette della speculazione metafisica ed etica. Gli scritti qui tradotti consentono, con l'aiuto dell'apparato critico, di dare corpo all’idea di una rinascita della filosofia, che riecheggia il titolo di una conferenza berlinese di Stumpf del 1907, ma che ben si attaglia al suo progetto filosofico complessivo.

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.
