This paper addresses the issue of how to best account for the diversity of our (synchronic) mental activities. The discussion starts with Mark Textor’s mental monism. According to mental monism, our mental life is constituted by just one simple mental act, in which different sub-acts can be conceptually distinguished. Textor grounds this view in the work of the early Brentano and contrasts it with the theory of the later Brentano, who introduces a mental substance into his philosophy. According to Textor, (...) Brentano needs a substance because he is unable to explain how mental monism can account for the separability of our mental activities, e.g. the fact that I can stop hearing F while still seeing blue. Textor argues, however, that mental monism can solve this problem. I address two issues regarding Textor’s view. First, I challenge his interpretation of Brentano by arguing that the early Brentano imports ontological complexity into our mental life; I defend Brentano’s view against possible criticisms, and I address some objections to mental monism. Second, I oppose Textor’s narrative about the mental substance. I argue that Brentano needs a substance not to explain separability, but rather to individuate our mental acts. I still argue, however, that Brentano’s earlier view (understood in my sense) is better than the substance account for dividing the mind. (shrink)

Both through his own work and that of his students, Franz Clemens Brentano had an often underappreciated influence on the course of 20 th - and 21 st -century philosophy. _The Routledge Handbook of Franz Brentano and the Brentano School_ offers full coverage of Brentano’s philosophy and his influence. It contains 38 brand-new essays from an international team of experts that offer a comprehensive view of Brentano’s central research areas—philosophy of mind, metaphysics, and value theory—as well as of the principal (...) figures shaped by Brentano’s school of thought. A General Introduction serves as an overview of Brentano and the contents of the volume and three separate bibliographies point students and researchers on to further avenues of inquiry. Systematic and detailed, _The Routledge Handbook of Franz Brentano and the Brentano School_ provides readers with a valuable reference to Brentano’s work, and to his lasting importance in the history of philosophy and in contemporary debates.

In this study, I propose to examine Marty's reconstruction of the general framework in which Brentano develops his theory of consciousness. My starting point is the formulation, at the very beginning of the second chapter of the second book of Brentano's Psychology, of two theses on mental phenomena, which constitute the basis of Brentano's theory of primary and secondary objects. In the second part, I examine the objection of infinite regress raised against Brentano's theory of primary and secondary objects and (...) Marty's interpretation of Brentano's theory of the unity of consciousness. The third part bears on the important distinction between implicit and explicit consciousness, which Brentano introduces in his lectures on descriptive psychology. Here, I analyse Marty's principle of individuation in light of the modifications which Brentano made to his theory of consciousness after the publication of his Psychology in 1874. The last section is an examination of Marty's conception of consciousness as self-consciousness with respect to his principle of individuation. (shrink)

Brentano held that every mental phenomenon has an object and is conscious (the dual relation thesis). The dual relation thesis faces a number of well-known problems. The paper explores how Brentano tried to overcome these problems. In considering Brentano's responses, the paper sheds light on Brentano's theory of judgement that underpins his philosophy of mind.

Husserl has undoubtedly considered himself being influenced by Brentano, but his conflicts with the orthodox core of the School of Brentano raise the question whether his adherence to Brentano suffices to adequately grasp the context of his early philosophy. I investigate the biographical details of Husserl’s studies in Vienna to uncover hitherto unknown ties between Husserl and Austrian philosophers outside the School of Brentano. Already during his secondary school studies in the Austro-Hungarian Monarchy Husserl was exposed to the philosophy textbooks (...) of Gustav Adolf Lindner; and archival records of the University of Vienna show that he had extensively attended philosophy courses held by other philosophers, especially by Robert Zimmermann. Both Lindner and Zimmermann proposed Herbartian philosophies, and what makes Zimmermann especially interesting is that he had once been a close personal disciple of Bernard Bolzano. I use an unpublished lecture transcript, written by a fellow student of Husserl, to investigate the controversial issue of Zimmermann’s possible transmission of Bolzano’s ideas. While a direct transmission seems improbable, my investigation uncovers a plethora of Herbartian influences, which are interesting on their own terms and have not only furnished Husserl with important parts of his descriptive psychological toolbox but have also helped him navigate the Brentano-School’s debate on intentionality.
