This study is about Carl Stumpf's achievements during his stay in Prague (1879-1884). It can be considered a piece of sociology of knowledge that is meant to uncover the institutional mechanisms used by Brentano from Vienna in order to implement his philosophical program in Prague. I claim that Stumpf and Marty have been instrumental in Brentano's plans and strategies to consolidate his hold on philosophy and its institutions in Austria. There are also several aspects of Stumpf's and Marty's scientific activities (...) in Prague, which I will also examine in this paper, including their scientific collaborations and exchanges with Ernst Mach, Ewald Hering, Gottlob Frege, and William James during Stumpf's stay in Prague (1879-1884). The last part of this study pertains to the circumstances surrounding Stumpf's departure from Prague and Brentano's reaction to Stumpf's arguments. (shrink)

This paper discusses the problems of an ontological value of the variable in Russell’s philosophy. The variable is essential in Russell’s theory of denotation, which among other things, purports to prove Meinongian being outside of subsistence and existence to be logically unnecessary. I argue that neither Russell’s epistemology nor his ontology can account for the ontological value of the variable without running into qualities of Meinongian being that Russell disputed. The problem is that the variable cannot be logically grounded by (...) Russell’s theory of denotation. As such, in so far as being is concerned, Meinong and Russell’s theories are much closer than is typically thought. The arguments are supported with concerns raised by Russell, Frege, and Moore regarding the ontological value of the variable. The problem can be summarised as follows: the variable is the fundamental denoting-position of a formal theory that is meant to explain the structure of the ontological. If such a formal theory is meant to ground the ontological, then the formal must also represent the actual structure of the ontological. Yet the variable, the fundamental symbol of denotation in a theory that defines objects, is ontologically indefinable. (shrink)

The article examines some aspects of Brentano's ontology, starting with his 1862 dissertation "On the ambiguity of Being according to Aristotle", as well as its influence on the philosophy of M. Heidegger. The author shows that the ontology of the early Brentano is not limited to ousiology, since it includes a discussion of the field of mental being (ens rationis, ὂν ὡς ἀληθές) and it is in this aspect that he influences the young Heidegger. Following Aristotle, Brentano assigns a central (...) role to the ontology of essence, which in the late period leads him to the position of reism, but in the lectures of the middle period Brentano discusses the problems of intentional inexistence, thanks to which projects of "new types of ontology" by Husserl and Mainong appear. The author believes that Heidegger was also influenced by these ideas. Of course, there are fundamental differences between the positions of Brentano and Heidegger, but the similarities are quite large. In particular, if Brentano, highlighting the real and true areas, gives preference in favor of the former, then Heidegger's ontology is built on the second member of this opposition. In particular, everything that can be given is called being by Heidegger, because we are talking about intentional being, about ens rationis, or ὂν ὡς ἀληθές. (shrink)

Perceptual disjunctivism, as I regard it in this paper, is the view that veridical perceptions and hallucinations, while indistinguishable via introspection, are states of fundamentally different kinds. This fundamental difference can be spelled out in various ways. According to the view I will be concerned with, it is a fundamental difference in the personal-level structure of both states. Against this version of disjunctivism, I will raise a new challenge. It is a variant of what can be seen as the standard (...) challenge against disjunctivism: how to do justice to the indistinguishability of veridical perceptions and hallucinations. It differs, however, from common versions of this challenge in where it locates the potential incompatibility of disjunctivism with the relevant fact of indistinguishability. Commonly, it is the disjunctivist assumption of a fundamental difference between both kinds of states which is regarded as incompatible with the indistinguishability of these states. In contrast, I will suggest that if hallucinations and veridical perceptions differed in the way proposed by structural disjunctivism, this difference would induce a corresponding difference in the psychological processes of their introspection and that the assumption of such a difference in the manner of introspection is most likely incompatible with a properly formulated indistinguishability claim.

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.
