Immanuel Kant was one of the leading lights of 18th-century philosophy; his work provided the foundations for later revolutionary thinkers such as Hegel and Marx. This work contains the keystone of his critical philosophy - the basis of human knowledge and truth.

∗ Apologies to Mark Hinchliff for stealing the title of his dissertation. (See Hinchliff, A Defense of Presentism. As it turns out, however, the version of Presentism defended here is different from the version defended by Hinchliff. See Section 3.1 below.).

Graham Priest presents a ground-breaking account of the semantics of intentional language--verbs such as "believes," "fears," "seeks," or "imagines." Towards Non-Being proceeds in terms of objects that may be either existent or non-existent, at worlds that may be either possible or impossible. 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 of fiction, the philosophy of mathematics, or cognitive (...) representation in AI.

Th ere is much controversy surrounding the nature of the relation between fictional individuals and possible individuals. Some have argued that no fictional individual is a possible individual; others have argued that (some) fictional individuals just are (merely) possible individuals. In this paper, I off er further grounds for believing the theory of fictional individuals defended by Amie Thomasson,viz., Artifactualism, by arguing that her view best allows one to make sense of this puzzling relation. More specifically, when we realize that (...) the view allows for an identification of merely possible individuals with fictional individuals, we seethat the utility, and hence the level of credence lent to Artifactualism, is increased. After arguing for this thesis, I respond to three of the most pressing worries. (shrink)

Thomas Reid was a philosopher who founded the Scottish school of 'common sense'. Much of Reid's work is a critique of his contemporary, David Hume, whose empiricism he rejects. In this work, written after Reid's appointment to a professorship at the university of Glasgow, and published in 1785, he turns his attention to ideas about perception, memory, conception, abstraction, judgement, reasoning and taste. He examines the work of his predecessors and contemporaries, arguing that 'when we find philosophers maintaining that there (...) is no heat in the fire, nor colour in the rainbow … we may be apt to think the whole to be only a dream of fanciful men, who have entangled themselves in cobwebs spun out of their own brain'. Written by one of the Scottish Enlightenment's most important thinkers, this work brings to life the intellectual debates of the time. (shrink)

This paper explores the view that there are such things as (nonexistent) fictional objects, and that we refer to such objects when we say things like "Sherlock Holmes is a fictional detective", or "Conan Doyle wrote about Sherlock Holmes". A theory of such objects is developed as a special application of a Meinongian Ontology.

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. (shrink)

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. 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. (shrink)

Thanks to the Inlaks Foundation in India, I was able to do my doctoral research on Our Talk About Nonexistents at Oxford in the early eighties. The two greatest philosophers of that heaven of analytical philosophy - Peter Strawson and Michael Dummett - supervised my work, reading and criticising all the fledgling philosophy that I wrote during those three years. At Sir Peter's request, Gareth Evans, shortly before his death, lent me an unpublished transcript of Kripke's John Locke Lectures. Work (...) on the Appendix about Indian Philosophy was supervised by the late Professor Bimal Krishna Matilal with whom informal but intense philosophical conversations used to spill over into dinner at his place almost every other day. It was Professor Matilal who sent me, over a summer, to study a tough Navya-Nyaya text under his own Nyaya teacher Pandit Visvabandhu Tarkatirtha at Calcutta. All four of these teachers were as kind to me as my life-long mentor in philosophy Professor Pranab Kumar Sen, whose clarity and depth remain the unreachable regu lative ideal of my intellect. When I came back to India, my life became blissfully free of the agonising anxiety to publish, until, after a conference at Jadavpur University where I gave an impromptu paper, ironically enough, on Non-doings, I met Derek Parfit. He had a six-hour conversation with me, explicitly planning my life. Five years had already elapsed since I had finished my D. Phil, but Derek read my thesis and liked it. (shrink)

Jeder wissenschaftlichen Theorie und jedem alltäglichen Weltbild liegen "ontologische Festlegungen" zugrunde, also Annahmen betreffend die Existenz bestimmter Gegenstände. Manchmal widersprechen implizite Existenzannahmen expliziten Überzeugungen und sind in diesem Sinne unerwünscht. Unerwünschte ontologische Festlegungen werfen unter anderem die folgenden Fragen auf: Nach welchen Kriterien kann entschieden werden, worauf jemand ontologisch festgelegt ist? Gibt es so etwas wie ein "ontologisch neutrales" Sprechen? Gibt es verschiedene "Weisen des Seins"? Wie können unerwünschte Festlegungen (etwa auf abstrakte, fiktive oder vergangene Gegenstände) vermieden werden? Welche Rolle (...) spielen dabei Paraphrasierungen, nicht-gegenständliche Deutungen der Quantifikation oder existenzfreie Logiken? Aus dem Inhalt: I. Ontologische Festlegung – 1.

A. Plantinga develops a challenging critique of Castañeda's guise theory, by identifying fundamental intuitions that guise theory gives up and by developing several objections to the guise-theoretic world view as a whole. In this paper, I examine whether Plantinga's criticisms apply to the theory of abstract objects. The theory of abstract objects and guise theory can be fruitfully compared because they share a common intellectual heritage---both follow Ernst Mally [1912] in postulating a special realm of objects distinguished by their "internal" (...) or "encoded" properties. Despite this common heritage, however, the theories organize, develop, and apply these special objects in distinctive ways. The two metaphysical systems, therefore, differ significantly, and these differences become important when one considers Plantinga's critique of guise theory. In this essay, the author shows that the theory of abstract objects anticipates and addresses most of Plantinga's concerns about guise theory, by preserving intuitions guise theory has abandoned.

This book tackles the issues that arise in connection with intensional logic -- a formal system for representing and explaining the apparent failures of certain important principles of inference such as the substitution of identicals and existential generalization -- and intentional states --mental states such as beliefs, hopes, and desires that are directed towards the world. The theory offers a unified explanation of the various kinds of inferential failures associated with intensional logic but also unifies the study of intensional contexts (...) and intentional states by grounding the explanation of both phenomena in a single theory. When an axiomatized realm of abstract entities is added to the metaphysical structure of the world, we can use them to identify and individuate the contents of directed mental states. The special abstract entities can be viewed as the objectified contents of mental files, and they play a crucial role in the analysis of truth conditions of the sentences involved in inferential failures.

In this book, Zalta attempts to lay the axiomatic foundations of metaphysics by developing and applying a (formal) theory of abstract objects. The cornerstones include a principle which presents precise conditions under which there are abstract objects and a principle which says when apparently distinct such objects are in fact identical. The principles are constructed out of a basic set of primitive notions, which are identified at the end of the Introduction, just before the theorizing begins. The main reason for (...) producing a theory which defines a logical space of abstract objects is that it may have a great deal of explanatory power. It is hoped that the data explained by means of the theory will be of interest to pure and applied metaphysicians, logicians and linguists, and pure and applied epistemologists. (shrink)

In formulating procreative principles, it makes sense to begin by thinking about whose interests ought to matter to us. Obviously, we care about those who exist. Less obviously, but still uncontroversially, we care about those who will exist. Ought we to care about those who might possibly, but will not actually, exist? Recently, unusual positions have been taken regarding merely possible people and the non-identity problem. David Velleman argues that what might have happened to you – an existent person – (...) often doesn't merit moral consideration since the alternative person one would have been had what might have happened actually happened is a merely possible person about whom one has no reason to care. He argues that his way of thinking can eliminate the non-identity problem. Caspar Hare argues that merely possible people have interests and are morally relevant. He argues that we can solve the non-identity problem by rejecting the view that merely possible people are morally irrelevant. Both Hare and Velleman argue that focusing on one's de dicto rather than on one's de re children can help us avoid the non-identity problem. I analyze the role that merely possible, nonexistent hypothetical entities ought to play in our moral reasoning, especially with regard to procreation. I refute both Velleman's and Hare's views and demonstrate the difficulties we encounter when we try to apply their views to common non-identity cases. I conclude with the common-sense view regarding who matters, morally: only those who do, did, or will exist. (shrink)

In his recent book on the philosophy of mind, Tim Crane has maintained that intentional objects are to be conceived as schematic entities, having no particular intrinsic nature. I take this metaphysical thesis as fundamentally correct. Yet in this paper I want to cast some doubts on whether this thesis prevents intentionalia, especially nonexistent ones, from belonging to the general inventory of what there is, as Crane seems to think. If my doubts are grounded, Crane’s treatment of intentionalia may further (...) be freed from a certain tension that seems to affect it, namely the fact that he appeals to nonexistent intentionalia in order to individuate intentional states and at the same time he attempts at dispensing with them.

In a recent paper, Anthony Everett has mounted a very serious attack against realism with respect to fictional entities. According to Everett, ficta raise deep logico-ontological worries, for they violate some basic logical laws and are problematically indeterminate with respect to both their existence and identity. Since an antirealist account for sentences apparently committing us to ficta is available, no such committment is really needed. In this paper I will try to show, first, that the antirealist account Everett proposes for (...) those sentences is not convincing. Moreover, by relying on the Meinongians’ distinctions between i) predicative and propositional negation and ii) either modes of predication or kinds of property, I will argue that the logico-ontological problems Everett arises against ficta can be solved. Finally, I will try to show that both the ‘modes of predication’- and the ‘kinds of property’- distinctions (especially the first one) are not so problematic as Everett holds. (shrink)

Meinong's object theory is primarily motivated by the needs of intentionality theory. I argue that Meinongian objects must be intensional entities if, as asked, they are to serve as the objects of thought in a purely object-theoretic account of intentionality. For Meinong, incomplete objects are the proper objects of thought. Complete objects are beyond our grasp; we apprehend them as best we can when we intend incomplete objects embedded in them. This yields, on a semantic plane, an account of failures (...) or substitutivity of identity in intentional contexts. And this, I argue, forces incomplete objects to be intensional, and so therefore are complete objects. (shrink)

For Meinong, familiarly, fictional entities are not created, but rather merely discovered (or picked out) from the inexhaustible realm of Aussersein (beyond being and non-being). The phenomenologist Roman Ingarden, in contrast, offers in his Literary Work of Art of 1931 a constructive ontology of fiction, which views fictional objects as entities which are created by the acts of an author (as laws, for example, are created by acts of parliament). We outline the logic of fiction which is implied by Ingarden’s (...) approach, showing how it distinguishes the properties possessed by fictional objects (for instance of having been created by such and such an author in such and such a work) from characteristics (for instance of smoking a pipe, of living in Baker Street) which are merely associated with such objects.

John Searle's Speech Acts and Expression and Meaning developed a highly original and influential approach to the study of language. But behind both works lay the assumption that the philosophy of language is in the end a branch of the philosophy of the mind: speech acts are forms of human action and represent just one example of the mind's capacity to relate the human organism to the world. The present book is concerned with these biologically fundamental capacities, and, though third (...) in the sequence, in effect it provides the philosophical foundations for the other two. Intentionality is taken to be the crucial mental phenomenon, and its analysis involves wide-ranging discussions of perception, action, causation, meaning, and reference. In all these areas John Searle has original and stimulating views. He ends with a resolution of the 'mind-body' problem. (shrink)

Fictional realism, i.e., the view that because fictions exist, fictional characters exist as well, has recently been accused of leading to inconsistency generated by phenomena of indeterminacy and inconsistency in fiction. We examine in detail four arguments against fictional realism, and present a version of fictional realism which can withstand those arguments.

I advance an objection to Graham Priest’s account of fictional entities as nonexistent objects. According to Priest, fictional characters do not have, in our world, the properties they are represented as having; for example, the property of being a bank clerk is possessed by Joseph K. not in our world but in other worlds. Priest claims that, in this way, his theory can include an unrestricted principle of characterization for objects. Now, some representational properties attributed to fictional characters, a kind (...) of fictional entities, involve a crucial reference to the world in which they are supposed to be instantiated. I argue that these representational properties are problematic for Priest’s theory and that he cannot accept an unrestricted version of the principle of characterization. Thus, while not refuting Priest’s theory, I show that it is no better off than other Meinongian theories. (shrink)

By a `denoting phrase' I mean a phrase such as any one of the following: a man, some man, any man, every man, all men, the present King of England, the present King of France, the center of mass of the solar system at the first instant of the twentieth century, the revolution of the earth round the sun, the revolution of the sun round the earth. Thus a phrase is denoting solely in virtue of its form. We may distinguish (...) three cases: (1) A phrase may be denoting, and yet not denote anything; e.g., `the present King of France'. (2) A phrase may denote one definite object; e.g., `the present King of England' denotes a certain man. (3) A phrase may denote ambiguously; e.g. `a man' denotes not many men, but an ambiguous man. The interpretation of such phrases is a matter of considerably difficulty; indeed, it is very hard to frame any theory not susceptible of formal refutation. All the difficulties with which I am acquainted are met, so far as I can discover, by the theory which I am about to explain. (shrink)

This essay re-examines Meinong's "Über Gegenstandstheorie" and undertakes a clarification and revision of it that is faithful to Meinong, overcomes the various objections to his theory, and is capable of offering solutions to various problems in philosophy of mind and philosophy of language. I then turn to a discussion of a historically and technically interesting Russell-style paradox (now known as "Clark's Paradox") that arises in the modified theory. I also examine the alternative Meinong-inspired theories of Hector-Neri Castañeda and Terence Parsons.

The canonical version of possible worlds semantics for story prefixes is due to David Lewis. This paper reassesses Lewis's theory and draws attention to some novel problems for his account.

Divided into two parts, the first concentrates on the logical properties of propositions, their relation to facts and sentences, and the parallel objects of commands and questions. The second part examines theories of intentionality and discusses the relationship between different theories of naming and different accounts of belief.

Towards Non-Being develops an account of the semantics of intentional predicates and operators. The account appeals to objects, both existent and non-existent, and worlds, both possible and impossible. This paper formulates replies to a number of the more interesting objections to the semantics that have been proposed since the book was published.

In this book Terence Parsons revives the older tradition of taking such objects at face value. Using various modern techniques from logic and the philosophy of language, he formulates a metaphysical theory of nonexistent objects. The theory is given a formalization in symbolism rich enough to contain definite descriptions, modal operators, and epistemic contexts, and the book includes a discussion which relates the formalized theory explicitly to English.

Fictional realists hold that fictional characters are real entities. However, Anthony Everett [“Against Fictional Realism”, Journal of Philosophy (2005)] notes that some fictions leave it indeterminate whether character A is identical to character B, while other fictions depict A as simultaneously identical and distinct from B. Everett argues that these fictions commit the realist to indeterminate and impossible identity relations among actual entities, and that as such realism is untenable. This paper defends fictional realism: for fictions depicting non-classical identity between (...) A and B, the realist should hold that there are two salient fragments, one with a single character (named both ‘A’ and ‘B’) and the other with two (named ‘A’ and ‘B’, respectively). Truth according to the fiction depicting indeterminate identity is determined by supervaluating over truth according to those salient fragments. For fictions depicting impossible identity, truth is determined by subvaluating over truth according to those two salient fragments. (shrink)

The simplest quantified modal logic combines classical quantification theory with the propositional modal logic K. The models of simple QML relativize predication to possible worlds and treat the quantifier as ranging over a single fixed domain of objects. But this simple QML has features that are objectionable to actualists. By contrast, Kripke-models, with their varying domains and restricted quantifiers, seem to eliminate these features. But in fact, Kripke-models also have features to which actualists object. Though these philosophers have introduced variations (...) on Kripke-models to eliminate their objectionable features, the most well-known variations all have difficulties of their own. The present authors reexamine simple QML and discover that, in addition to having a possibilist interpretation, it has an actualist interpretation as well. By introducing a new sort of existing abstract entity, the contingently nonconcrete, they show that the seeming drawbacks of the simplest QML are not drawbacks at all. Thus, simple QML is independent of certain metaphysical questions. (shrink)

The essays collected in this volume are all concerned with the connection between fiction and truth. This question is of utmost importance to metaphysics, philosophy of language, philosophical logic and epistemology, raising in each of these areas and at their intersections a large number of issues related to creation, existence, reference, identity, modality, belief, assertion, imagination, pretense, etc. All these topics and many more are addressed in this collection, which brings together original essays written from various points of view by (...) philosophers of diverse trends. These essays constitute major contributions to the current debates that the connection between truth and fiction continually enlivens, and give a sense of the directions in which research on this question is heading.
