In several manuscripts, written between 1894 and 1897, Twardowski developed a new theory of judgement with two types of judgement: existential and relational judgements. In Zur Lehre he tried to stay within a Brentanian framework, although he introduced the distinction between content and object in the theory of judgement. The introduction of this distinction forced Twardowski to revise further Brentano'stheory.His changes concerned judgements about relations and about non-present objects. The latter are considered special cases of relational judgements. The existential judgements (...) are analysed in a Brentanian way; whereas relational judgements are analysed in a Brentanian way only as far as the act is concerned, but not when it comes to the object: the object of a relational judgement is a relationship. With this notion of relationship Twardowski comes close to introducing a concept of state of affairs for the object of (relational) judgements. (shrink)

This compelling reevaluation of the relationship between logic and knowledge affirms the key role that the notion of judgement must play in such a review. The commentary repatriates the concept of judgement in the discussion, banished in recent times by the logical positivism of Wittgenstein, Hilbert and Schlick, and the Platonism of Bolzano. The volume commences with the insights of Swedish philosopher Per Martin-Löf, the father of constructive type theory, for whom logic is a demonstrative science in which judgement is (...) a settled feature of the landscape. His paper opens the first of four sections that examine, in turn, historical philosophical assessments of judgement and reason; their place in early modern philosophy; the notion of judgement and logical theory in Wolff, Kant and Neo-Kantians like Windelband; their development in the Husserlian phenomenological paradigm; and the work of Bolzano, Russell and Frege. The papers, whose authors include Per Martin-Löf, Göran Sundholm, Michael Della Rocca and Robin Rollinger, represent a finely judged editorial selection highlighting work on philosophers exercised by the question of whether or not an epistemic notion of judgement has a role to play in logic. The volume will be of profound interest to students and academicians for its application of historical developments in philosophy to the solution of vexatious contemporary issues in the foundation of logic. ​.

The dominant theory of judgment in 1870 was one or other variety of combination theory: the act of judgment is an act of combining concepts or ideas in the mind of the judging subject. In the decades to follow a succession of alternative theories arose to address defects in the combination theory, starting with Bolzano’s theory of propositions in themselves, Brentano’s theory of judgment as affirmation or denial of existence, theories distinguishing judgment act from judgment content advanced by Brentano’s students (...) Twardowski, Husserl and Meinong, and finally, Adolf Reinach’s addition of a linguistic dimension to the Brentano-Husserlian theory of judgment – an account of judgments as ways of doing things with words in what Reinach called ‘social acts’.

The paper considers F. Brentano’s judgement theory and its influence upon the develop-ment of analytical philosophy. It is asserted that this judgement theory in Brentano’s reistic ontology, using the notion of accidental extension, leads to the creation of the existence of things “by word”. Such an “art” becomes possible only when the “accidental extension” is treated as an aesthetic or ethic evaluation. Brentano owes the separation of a logical evalua-tion of “truth” to Descartes’ dualism. Judgement theory does not satisfy the (...) criterion of in-tersubjectivity. Therefore Brentano as well as his admirers must read the judgements by de-scription. It is stated that the description defence mechanism against the expression of the presented subject in language lies in the fact that it does not allow for the unique junction in the composition of the description of existence and essence (accidental extension), allowing to express the existence of only a part of the presented subject.

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.

When the original Dutch version of this book was presented in 1971 to the University of Leiden as a thesis for the Doctorate in philosophy, I was prevented by the academic mores of that university from expressing my sincere thanks to three members of the Philosophical Faculty for their support of and interest in my pursuits. I take the liberty of doing so now, two and a half years later. First and foremost I want to thank Professor G. Nuchelmans warmly (...) for his expert guidance of my research. A number of my most im portant sources were brought to my attention by him. During the whole process of composing this book his criticism and encouragement were carried out in a truly academic spirit. He thereby provided working conditions that are a sine qua non for every author who is attempting to approach controversial matters in a scientific manner, conditions which, however, were not easily available at that time. In a later phase I also came into contact with Professors L. M. de Rijk and J. B. Ubbink, with both of whom I had highly stimulating discussions and exchanges of ideas. The present edition contains some entirely new sections, viz. 1-9, IV-29, V-9, V-20, VII-14 (iii), (iv), VII-17 (i), VIII-22, IX-17, IX-19, X-9 and XI-8. Section X-9 was inspired by a remark made by Professor A. (shrink)

‘Judgment’ is Brentano’s terms for any mental state liable to be true or false. This includes not only the products of conceptual thought, such as belief, but also perceptual experiences, such as seeing that the window was left open. ‘Every perception counts as a judgment,’ writes Brentano (1874: II, 50/1973a: 209). Accordingly, his theory of judgment is not exactly a theory of the same phenomenon we call today ‘judgment,’ but of a larger class of phenomena one (perhaps the main) species (...) of which is what we call judgment. Even if we keep this in mind, though, the profound heterodoxy of Brentano’s theory of judgment is still striking. Brentano develops this heterodox theory in some detail already in the Psychology from Empirical Standpoint (Brentano 1874/1973a). But he continued to work out its details, and various aspects of it, until his death. Many of the relevant articles, notes, and fragments of relevance have been collected by Oskar Kraus in 1930 and published under the title Truth and Evidence (Brentano 1930/1966b). Kraus prefaces this volume with an elaborate reconstruction, of dubious plausibility, according to which Brentano’s accounts of judgment and truth have gone through four distinct stages. In reality, there is a unified underlying conviction underwriting Brentano’s work both on judgment and on truth (see CHAP. 20 on the latter). Here I present this unified core of this highly original theory of judgment, which can be captured in terms of three main theses. The first is that contrary to appearances, all judgments are existential judgments (§1). The second is that the existential force of judgment is indeed a force, or mode, or attitude – it does not come from the judgment’s content (§2). The third is that judgment is not a propositional attitude but an ‘objectual’ attitude (§3). (shrink)
