The Logic of Intentional Objects

The Logic of Intentional Objects PDF Author: Jacek Pasniczek
Publisher: Springer Science & Business Media
ISBN: 9401589968
Category : Philosophy
Languages : en
Pages : 224

Book Description
Intentionality is one of the most frequently discussed topics in contemporary phenomenology and analytic philosophy. This book investigates intentionality from the point of view of intentional objects. According to the classical approach to this concept, whatever can be consciously experienced is regarded as an intentional object. Thus, not only ordinary existing individuals but also various kinds of non-existents and non-individuals are considered as intentional (including such bizarre entities as quantifier objects: `some dog', `every dog'). Alexius Meinong, an Austrian philosopher, is particularly well-known as the `inventor' of an abundant ontology of objects among which even incomplete and impossible ones, like `the round square', find their place. Drawing inspirations from Meinong's ideas, the author develops a simple logic of intentional objects, M-logic. M-logic closely resembles classical first-order logic and, as opposed to the formally complicated contemporary theories of non-existent objects, it is much more friendly in apprehending and applications. However, despite this resemblance, the ontological content of M-logic far exceeds that of classical logic. In this book formal investigations are intertwined with philosophical analyses. On the one hand, M-logic is used as a tool for investigating formal features of intentional objects. On the other hand, the study of intentionality phenomena suggests further ways of extending and modifying M-logic. Audience: The book is addressed to logicians, cognitive scientists, philosophers of language and metaphysics with either a phenomenological or an analytic background.

Objects and Modalities

Objects and Modalities PDF Author: Tero Tulenheimo
Publisher: Springer
ISBN: 3319531190
Category : Philosophy
Languages : en
Pages : 208

Book Description
This book develops a novel generalization of possible world semantics, called ‘world line semantics’, which recognizes worlds and links between world-bound objects (world lines) as mutually independent aspects of modal semantics. Addressing a wide range of questions vital for contemporary debates in logic and philosophy of language and offering new tools for theoretical linguistics and knowledge representation, the book proposes a radically new paradigm in modal semantics. This framework is motivated philosophically, viewing a structure of world lines as a precondition of modal talk. The author provides a uniform analysis of quantification over individuals (physical objects) and objects of thought (intentional objects). The semantic account of what it means to speak of intentional objects throws new light on accounts of intentionality and singular thought in the philosophy of mind and offers novel insights into the semantics of intensional transitive verbs.

The Objects of Thought

The Objects of Thought PDF Author: Tim Crane
Publisher: Oxford University Press
ISBN: 0199682747
Category : Philosophy
Languages : en
Pages : 195

Book Description
Tim Crane addresses the ancient question of how it is possible to think about what does not exist. He argues that the representation of the non-existent is a pervasive feature of our thought about the world, and that to understand thought's representational power ('intentionality') we need to understand the representation of the non-existent.

Towards Non-Being

Towards Non-Being PDF Author: Graham Priest
Publisher: Oxford University Press on Demand
ISBN: 0199262543
Category : Mathematics
Languages : en
Pages : 207

Book Description
Towards Non-Being presents an account of the semantics of intentional language - verbs such as 'believes', 'fears', 'seeks', 'imagines'. Graham Priest's account tackles problems concerning intentional states which are often brushed under the carpet in discussions of intentionality, such as their failure to be closed under deducibility. Drawing on the work of the late Richard Routley (Sylvan), it proceeds in terms of objects that may be either existent or non-existent, atworlds that may be either possible or impossible. Since Russell, non-existent objects have had a bad press in Western philosophy; Priest mounts a full-scale defence. In the process, he offers an account of both fictional and mathematical objects as non-existent.The book will be of central interest to anyone who is concerned with intentionality in the philosophy of mind or philosophy of language, the metaphysics of existence and identity, the philosophy or fiction, the philosophy of mathematics, or cognitive representation in AI.

This updated second edition adds ten new chapters to the original eight. These further develop the ideas of the first edition, reply to critics, and explore new areas of relevance. New topics covered include: conceivability, realism/antirealism concerning non-existent objects, self-deception, and the verb to be.

Husserl and Intentionality

Husserl and Intentionality PDF Author: D.W Smith
Publisher: Springer Science & Business Media
ISBN: 9401093830
Category : Philosophy
Languages : en
Pages : 444

Book Description
This book has roots in our respective doctoral dissertations, both completed in 1970 at Stanford under the tutelage of Professors Dagfmn F øllesdal, John D. Goheen, and Jaakko Hintikka. In the fall of 1970 we wrote a joint article that proved to be a prolegomenon to the present work, our 'Intentionality via Intensions', The Journal of Philosophy 68 (1971). Professor Hintikka then suggested we write a joint book, and in the spring of 1971 we began writing the present work. The project was to last ten years as our conception of the project continued to grow at each stage. Our iritellectual debts follow the history of our project. During our dis sertation days at Stanford, we joined with fellow doctoral candidates John Lad and Michael Sukale and Professors Føllesdal, Goheen, and Hintikka in an informal seminar on phenomenology that met weekly from June of 1969 through March of 1970. During the summers of 1973 and 1974 we regrouped in another informal seminar on phenomenology, meeting weekly at Stanford and sometimes Berkeley, the regular participants being ourselves, Hubert Dreyfus, Dagfmn Føllesdal, Jane Lipsky McIntyre, Izchak Miller, and, in 1974, John Haugeland.

Meinong on Meaning and Truth

Meinong on Meaning and Truth PDF Author: Anna Sierszulska
Publisher: Walter de Gruyter
ISBN: 3110325667
Category : Philosophy
Languages : en
Pages : 263

Book Description
The study aims at exposing Meinong's ideas that may be of interest to analytic philosophers. It contains all the basic information concerning Meinong's theory of objects with a special focus upon 'objectives', which are Meinong's propositions. Meinong's theory of meaning and his epistemological views are discussed in detail. An outline of his conception of truth, which is classified as firmly realistic, is followed by a review of the critical works touching upon Meinong's epistemological ideas. Finally, Meinong's theory of objects is presented as inspiring the development of Meinongian logics, with his Aussersein as the prototype of an all-inclusive semantic domain. The issues considered include reference of terms and sentences as well as the general features of a Meinongian-style semantics.

The Act and Object of Judgment

The Act and Object of Judgment PDF Author: Brian Ball
Publisher: Routledge
ISBN: 0429787618
Category : Philosophy
Languages : en
Pages : 267

Book Description
This book presents 12 original essays on historical and contemporary philosophical discussions of judgment. The central issues explored in this volume can be separated into two groups namely, those concerning the act and object of judgment. What kind of act is judgment? How is it related to a range of other mental acts, states, and dispositions? Where and how does assertive force enter in? Is there a distinct category of negative judgments, or are these simply judgments whose objects are negative? Concerning the object of judgment: How many objects are there of a given judgment? One, as on the dual relation theory of Frege and Moore? Or many as in Russell’s later multiple relation theory? If there is a single object, is it a proposition? And if so, is it a force-neutral, abstract entity that might equally figure as the object of a range of intentional attitudes? Or is it somehow constitutively tied to the act itself? These and related questions are approached from a variety of historical and contemporary perspectives. This book sheds new light on current controversies by drawing on the details of the distinct intellectual contexts in which previous philosophers’ positions about the nature of judgment were formulated. In turn, new directions in present-day research promise to raise novel interpretive prospects and challenges in the history of philosophy.
