The paper argues that Brentano was the exponent of a methodological monism, which is based on the requirement that science should be grounded on experience, and not on a speculative-idealistic principle, as in the case of German idealism. In Brentano’s psychological writings, this methodological requirement concretized in two different theses: (T1) The method of psychology is identical with the method of natural science; (T2) The method of psychology is inspired by the method of natural science. The thesis of this study (...) is that an important part of Psychology from an Empirical Standpoint is elaborated in accordance with T1. By contrast, Brentano’s Descriptive Psychology illustrates the subsequent decision to give up this idea. In its place, the aforementioned requirement is elaborated in the spirit of a methodological particularism that recommends the scientist elaborate his methods according to the specificity of the phenomena under investigation and to the difficulties that need to be overcome when approaching them.

In the well-known intentionality quote of his Psychology from an Empirical Standpoint, Brentano characterises the mental phenomena through the following features: (i) the intentional inexistence of an object, (ii) the relation to a content, and (iii) the direction toward an object. The text argues that this characterisation is not general because the direction toward an object does not apply to the mental phenomena of sensation. The second part of the paper analyses the consequences that ensue from here for the Brentanian (...) classification of mental phenomena: in Brentano’s psychology one can distinguish two concepts of mental phenomena − the mental phenomenon in a broad sense and the mental phenomenon in a narrow sense; the former concept allows the separation of the mental from the physical, while the narrow concept allows the distinguishing of the main classes of mental phenomena. The third part of the paper shows that, with respect to sensation, the absence of a direction toward an object is compatible with both Brentano’s early taxonomies of philosophical sciences, and his early program for the establishment of a new, empirical and non-speculative philosophy. For this reason, I hold that intentionality is important for the foundation of both psychology, and empirical philosophy. (shrink)

The paper defends the following thesis: the intentionality passage from Brentano’s Psychology from an Empirical Standpoint (1874) can be interpre- ted from two perspectives: intentionality as the most salient distinguishing feature separating the mental from the physical, and intentionality as a the- ory of the way in which mental acts, with their contents, are related to ex- tra-mental objects. Fundamentally, the theory of intentionality from 1874 is an example of the former. Its role is that of allowing the establishment of (...) psychology as a science. However, it can also be understood as a theory of intentionality in the second sense through a clarification of the relations it entails between the content and the object of the act. For this reason, it could be said that the act–content–extra-mental object distinction was already achieved in the 1874 work, at least at the level of sensory acts. The distinction between the psychical act, the content, and the object presen- ted through this content was already made in the EL 80 Logik manuscript from 1869/70 at the level of nominal presentation, which provides a fur- ther argument for the above thesis.

R. M. Chisholm interprets Brentano’s theory of intentionality through the lens of two theses: the ontological thesis, according to which the intentionality of the mental designates the fact that there is an immanent object in the act; and the psychological thesis, according to which intentionality consists of the direction of the mental act toward the extra-mental object. In my paper I interpret Chisholm’s and Brentano’s theses on intentionality from two perspectives: intentionality as the most salient distinguishing feature separating the mental (...) from the physical (Chisholm’s ontological thesis), and intentionality as a theory of the way in which mental acts with their content are related to extra-mental but theoretically-constructed objects of physics (Chisholm’s psychological thesis). Thus, an important issue of my paper is also to show that Chisholm’s well-known ontological and psychological theses on Brentanian intentionality rest on presuppositions that do not fit the program of Brentanian psychology.

Die Abhandlung entwickelt und vertritt folgende Thesen: (1) Brentanos Vier-Phasen-Theorie wurde unabhängig von Comtes Drei-Stadien-Gesetz entworfen . (2) Aber Brentano legte großen Wert darauf, die Übereinstim- mung beider Theorien zu unterstreichen . (3) Beide Theorien gehen von verschiedenen Geschichtsauffassungen aus: Comtes Theorie schließt die Geschichte der fundamentalen positiven Wissenschaften ein, die geradli- nig verläuft, stets aufwärts führt und durch keine gesetzmäßig auftretenden Verfallsphasen belastet wird, aber dennoch Stagnationen kennt . Dagegen bezieht sich Brentanos Theorie vorwiegend auf die Geschichte der Philo- (...) sophie, allerdings indirekt auch auf die schönen Künste . Dabei verlaufen die historischen Entwicklungen zyklisch und kennen Perioden des wissen- schaftlichen Auf- und Niederganges, die sich wiederholen . (4) Beide The- orien enthalten verschiedene Strategien, die auf eine grundlegende Erneu- erung der Philosophie abzielen . Für Comte gilt, dass die neue Philosophie positiv und unabhängig von der philosophischen Tradition arbeiten müsse . Dagegen vertritt Brentano die Auffassung, nach der die Philosophie von ihrer Methode her der Naturwissenschaft analog empirisch forscht und da- bei der philosophischen Tradition prinzipiell verpflichtet bleibt.
