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 most obvious varieties of mental phenomena directed to non- existent objects occur in our experiences of works of art. The task of applying the Meinongian ontology of the non-existent to the working out of a theory of aesthetic phenomena was however carried out not by Meinong by his disciple Stephan Witasek in his Grundzüge der allgemeinen Ästhetik of 1904. Witasek shows in detail how our feelings undergo certain sorts of structural modifications when they are directed towards what does not (...) exist. He draws a distinction between genuine mental phenomena and what he calls `phantasy-material', asserting that `the job of the aesthetic object, whether it is a work of art or a product of nature, is to excite and support the actualisation of phantasy-material in the experiencing subject'. We might think of such phantasy-material as a matter of Ersatz-emotions or emotional `slop'. We could then see Witasek's aesthetics as an elaborate taxonomy of the various different sorts of Ersatz-emotions which the subject allows to be stimulated within himself in his intercourse with works of art, and see works of art themselves as machines for the production of ever more subtle varieties of such phantasy-material in the perceiving subject.

It is widely known that Kasimir Twardowski was a student of Franz Brentano. In view of the fact that Brentano generally had great impact through his lectures, especially during his Vienna period (1874-1895), and consequently became one of the towering figures of Austrian philosophy, it is a matter of no small interest to determine how he influenced Twardowski. I’ll first consider presentations as they are described in Brentano’s psychology and then proceed to discuss Brentano’s account of the latter in his (...) logic. (shrink)

This paper accomplishes two tasks. First, I examine in detail Edmund Husserl’s earliest philosophy of surrogates, as it is found in his 1890 “On the Logic of Signs ”. I analyze his psychological and logical investigations of surrogates, where the former is concerned with explaining how these signs function and the latter with how they do so reliably. His differentiation of surrogates on the basis of their genetic origins and degrees of necessity is discussed. Second, the historical importance of this (...) text is disclosed by showing how Semiotic serves as both the inspiration for, and the foil to, Husserl’s 1901 First Logical Investigation. Husserl not only adopts the idea that linguistic signs can function via association, but also maintains that such signs can motivate me to execute one of two experiences. The key difference between the texts is that Husserl abandons his theory of surrogates in 1901, instead holding that I can experience absent objects by means of empty intentions. The reasons why Husserl found it necessary to transform this tenet of his philosophy are discussed at length. (shrink)

The paper contends that abstraction lies at the core of the philosophical and methodological rupture that occurred between Husserl and his mentor Franz Brentano. To accomplish this, it explores the notion of abstraction at work in these two thinkers’ methodological discussions through their respective claims regarding the structure of consciousness, and shows that how Husserl and Brentano analyze the structure of consciousness conditions and strictly delineates the nature and reach of their methods of inquiry. The paper pays close attention to (...) intentionality, founding (Fundierung), and qualitative modification (qualitative Modifikation) understood as principles of consciousness. While intentionality has been the topic of numerous discussions surrounding these two thinkers’ work, founding and qualitative modification have slipped under the radar despite the fact that they hold—as I intend to show—the key to shedding new light on their respective methods of inquiry. More specifically, the paper explicates the ways in which Brentano’s notion of founding (understood as a relationship between whole acts) and his failure to identify radical-qualitative modification as a principle of consciousness preclude him from offering a successful model for philosophical universalizing thought. It is my hope to show that Husserl’s rethinking of founding as a relationship between certain structural moments of acts along with his novel notion of qualitative modification ground his attempt to carve a new method of philosophical inquiry—albeit jejune and ambiguous at the time of the Investigations, yet nevertheless able to successfully negotiate the problems faced by his predecessor.

This dissertation explores and argues for the import of the imagination (Phantasie) in Edmund Husserl's phenomenological method of inquiry. It contends that Husserl's extensive analyses of the imagination influenced how he came to conceive the phenomenological method throughout the main stages of his philosophical career. The work clarifies Husserl's complex method of investigation by considering the role of the imagination in his main methodological apparatuses: the phenomenological, eidetic, and transcendental reductions, and eidetic variation - all of which remained ambiguous despite (...) his extensive programmatic discussions. The work illuminates and clarifies aspects of the Husserlian phenomenological method never before explored. -/- In order to clarify Husserl's eidetic method of inquiry, I propose a new way of thinking about the imagination - as direct intuitive presentation (eigentliche anschauliche Vorstellung) and as horizonal-nexic level of consciousness exhibiting the neutrality, freedom, and possibility as its essential features. Following Husserl's studies of the imagination, I propose a three-level model of consciousness (realizing, imagining, and eidetic) and explore the dynamic flexibility of each level (as horizon within which acts such as judgments or memories can unfold). This model of consciousness allows for a rethinking of the sources and conditions for the possibility of eidetic phenomenological inquiry - topics Husserl was mostly silent about. -/- Through a rethinking of the model of consciousness, I propose a tight and substantial relationship between the natural (everyday) and artificial (methodological, theoretical) attitudes. I argue that the structure and systems of possibilities pertaining to the artificial attitude - i.e., our actual as well as possible methodological tools - are structurally and well as informationally bound to the structure and system of possibilities pertaining to the natural attitude. In order to explore the nature of the relationship between these two attitudes I argue that we must take a closer look at the structure and abilities of imagining consciousness - the sole nexic-horizonal level that can function both naturally and artificially. This insight regarding the nature of consciousness clarifies Husserl's transcendental idealism in its intimate connection to the everyday. Understanding Husserl's philosophical stance is thus purged of all possibility of mistakenly labeling it as entailing immanent detachment, solipsism, or Platonic idealism. (shrink)
