Is it possible to prove or disprove God's existence? Arguments for the existence of God have taken many different forms over the centuries: in The Non-Existence of God, Nicholas Everitt considers all of the arguments and examines the role that reason and knowledge play in the debate over God's existence. He draws on recent scientific disputes over neo-Darwinism, the implication of 'big bang' cosmology, and the temporal and spatial size of the universe; and discusses some of (...) the most recent work on the subject, leading to a controversial conclusion.

This chapter focuses on two clusters of questions concerning existence. The first cluster concerns the scope of existence, examining how wide the domain of existing things is and whether it encompass absolutely everything. The second cluster concerns vagueness and indeterminacy, explaining whether vague things and vague categories of things are there or all vagueness is a matter of referring indifferently to a large number of absolutely precise things and showing the ultimate source of vagueness. There are two theories (...) of vagueness, epistemic and metaphysical. The chapter focuses on Meinongian definitions of 'existence' and examines four arguments in favor of Anti‐Actualism. The first and second respectively appeals to common sense and the need for intentional objects, that is, objects of certain mental attitudes. The third appeals to the need for fictional and illusory entities. And the fourth appeals to the need for non‐existent things as constituents of certain merely possible situations. (shrink)

That certain paper bills have monetary value, that Vladimir Putin is the president of Russia, and that Prince Philip is the husband of Queen Elizabeth II: such facts are commonly called ‘institutional facts’. IFF are, by definition, facts that exist by virtue of collective recognition. The standard view or tacit belief is that such facts really exist. In this paper we argue, however, that they really do not—they really are just well-established illusions. We confront realism about IFF with six criteria (...) of existence, three established and three less so but highly intuitive. We argue that they all tell against the existence of IFF. An obvious objection to IFF non-realism is that since people’s behaviour clearly reflects the existence of IFF, denying their existence leaves an explanatory gap. We reject this argument by introducing a variant of the so-called ‘Thomas Theorem,’ which says that when people collectively recognize a fact as existing, they largely behave accordingly, regardless of whether that fact really exists or not.

First it will be necessary to examine the argument, and the meaning of the argument, by which Mr. Ingram-Pearson is led to uphold such an unusual position. Using the statement, "fairies do not exist," as his example, he observes: "In order to achieve its obvious status as a denial this statement must have some object of reference for its subject term; for denials which are denials of nothing are not denials in any sense at all." What, then, is the designate (...) of the term "fairies"? It is, we are told, "an existent [italics mine] which at least one person believes to be present in the world and which another person at the same time and in the same context believes is not there." To say that "fairies do not exist" is therefore to say that "certain entities, designated by the term 'fairies,' are not present in the world," or "specific entities, designated by the term 'fairies,' are really absent from the world." The latter statement is positive, and Mr. Ingram-Pearson tells us explicitly that positive statements cannot "succeed in making intelligible" something made intelligible by negative statements about non-existents; but he has in mind such "ordinary" positive statements as "fairies are imagined beings." In other words, it is not that negative statements about. (shrink)

This paper is a preliminary study of Bhāviveka’s Svātantrika-Mādhyamika justifications for taking non-existent things as the subject of an inference, based on his Dacheng Zhangzhen Lun. Bhāviveka’s treatment of inference is similar to that of Dignāga in that the subject is required to be existent. Bhāviveka also holds that, in a conventional sense, words refer to universals and to the existent entities that possess them, while the two are cognised together. However, in his inference for the unreality of unconditioned things, (...) he likens these things to a sky-flower that never arises and is unreal even conventionally. This paper first demonstrates how taking unconditioned things as the subject of an inference can be problematic for Bhāviveka. Then, it discusses Bhāviveka’s attempts to address the problems by subsuming the unconditioned things under the domain of conventional reality. The paper concludes that these attempts show his flexibility in terms of what is taken as conventionally real. (shrink)

This essay examines the role of non-existent objects in "epistemological ontology" — the study of the entities that make thinking possible. An earlier revision of Meinong's Theory of Objects is reviewed, Meinong's notions of Quasisein and Außersein are discussed, and a theory of Meinongian objects as "combinatorially possible" entities is presented.

Sabzawari is one of the greatest Muslim philosophers of the nineteenth century. He belongs to Sadrian Existentialism, which became a dominant philosophical tradition during the Qajar dynasty in Iran. This paper critically analyses Sabzawari’s ontological discussion on the dichotomy of existence and quiddity and the relation between existence and non-existence. It argues against Sabzawari by advocating the idea that ‘Existence’ rather than quiddity is the ground for identity as well as for diversity, and that non-existence, (...) like existence, is able to produce an effect.

We show that the non-existence of mad families is equiconsistent with \, answering an old question of Mathias. We also consider the above result in the general context of maximal independent sets in Borel graphs, and we construct a Borel graph G such that \ “there is no maximal independent set in G” is equiconsistent with \ “there exists an inaccessible cardinal”.

According to the “deprivation approach,” a person’s death is bad for her to the extent that it deprives her of goods. This approach faces the Lucretian problem that prenatal non-existence deprives us of goods just as much as death does, but does not seem bad at all. The two most prominent responses to this challenge—one of which is provided by Frederik Kaufman (inspired by Thomas Nagel) and the other by Anthony Brueckner and John Martin Fischer—claim that prenatal non-existence (...) is relevantly different from death. This paper criticizes these responses. (shrink)

We have argued that it is rational to have asymmetric attitudes toward prenatal and posthumous non-existence insofar as this asymmetry is a special case of a more general (and arguably rational) asymmetry in our attitudes toward past and future pleasures. Here we respond to an interesting critique of our view by Jens Johansson. We contend that his critique involves a crucial and illicit switch in temporal perspectives in the process of considering modal claims (sending us to other possible worlds).

The Nyāya philosopher Udayana devotes the first chapter of his Ātmatattvaviveka to refuting the Buddhist thesis of universal momentariness—the view that nothing which exists can persist through time—and to establishing the contrary view that things can and do persist. In the course of his critique of the Buddhists' "inference from existence" which purports to establish the momentariness thesis, Udayana is forced to consider the problem of how, if at all, it is possible to meaningfully and reliably think and talk (...) about things which do not exist.In this paper, I offer a close reading of this section of the ĀTV, taking seriously both the philosophical context and commitments of Udayana's work in general, and the...

Does the real world, defined as a world of objects that exist independent of human interests, concerns, and cognitive activities, really exist? Jan Westerhoff argues that we have good reason to believe it does not. His discussion considers four main facets of the idea of the real world, ranging from the existence of a separate external and internal world, to the existence of an ontological foundation that grounds the existence of all the entities in the world, and (...) the existence of an ultimately true theory that provides a final account of all there is. As Westerhoff discusses the reasons for rejecting the postulation of an external world behind our representations, he asserts that the internal world is not as epistemically transparent as is usually assumed, and that there are good reasons for adopting an anti-foundational account of ontological dependence. Drawing on conclusions from the ancient Indian philosophical system of Madhyamaka Buddhism, Westerhoff defends his stance in a purely Western philosophical framework, and affirms that ontology, and philosophy more generally, need not be conceived as providing an ultimately true theory of the world.

Cet article est destiné à montrer qu’antérieurement au développement par Ockham d’une doctrine de l’intuition du non-existant, deux théologiens parisiens avaient déjà construit, chacun à sa manière, une théorie de la connaissance intuitive qui établissait, contre Duns Scot, la possibilité de l’intuition d’une chose non-existante ou absente : Gérard de Bologne et Hervé de Nédellec. L’étude philosophique de ce thème chez ces deux penseurs s’appuie sur l’édition critique de leurs Quodlibeta qu’a réalisée l’auteur de l’article.

Consider predicates like 'is a fictional character' and 'is a mythical object'. Since their ascription entails a corresponding Negative Existential claim, call these 'NE-characterizing predicates'. Objectualists such as Parsons, Sylvan, van Inwagen, and Zalta think that NE-characterizing properties are genuine properties of genuinely non-existent objects. But how, then, to make room for statements like 'Vulcan is a failed posit' and 'that little green man is a trick of the light'? The predicates involved seem equally NE-characterizing yet on the surface fail (...) to mark a genuine property o f things. Instead, the truth of such predications strongly supervenes on types of referential failure. Kendall Walton's anti-objectualist account of talk about fiction provides a neat solution to this supervenience problem by invoking special games of make-believe. The present paper claims that while Walton's view thereby gains an important advantage over objectualism, the solution faces problems of its own. The rest of the paper desribes another solution, one that assigns a large role to the idea of metaphor. (shrink)

An attempt is made in the present essay to accommodate various senses of the notion of existence and ofthat of non-existence within the framework of logic. With this aim in view a system of Lesniewski's Ontology, referred to as System S, is outlined. Equipped with appropriate definitions and illustrated with a selection of theses it offers a logical theory of existence and non-existence. The usefulness of the theory is then tested by interpreting in its terms some (...) of the principal notions and assertions of Meinong's ontology. A few brief comments on the notion of 'possible object' and on 'semantics' of fiction conclude the essay. (shrink)

Can we refer to objects which do not exist? Searle says that we cannot. He postulates an ‘axiom of existence’ such that, if an object does not exist, we cannot refer to it. This ‘axiom of existence’ could be taken simply as a way of defining the notion of ‘reference’; we would not count a reference to a non-existent object as a ‘reference’ in the philosophical sense; or perhaps it might count as a reference but not as a (...) ‘successful’ or ‘consummated’ reference, to use the terminology which Searle sometimes adopts. Whichever way we take Searle's doctrine I wish to argue that it is objectionable. The conceptual scheme he advocates obscures the truth. But I do not deny that there is a temptation to resort to it, and I hope to show that, where lawyers have yielded to the temptation, pernicious doctrines have resulted. (shrink)

This article concerns the work of the prime movers of the Neo-Meinongian “revival,” Terry Parsons and Richard Routley, and specifically their solution to the issue of how to formulate the Characterisation Principle (a thing that is so and so, is so and so). Both adopted variations of the nuclear/non-nuclear (characterising/non-characterising) strategy. This article discusses their implementations of the strategy and its problems.

In this discussion of Colin McGinn's book, 'Logical Properties', I comment first on the chapter "Existence", then on the chapter "Modality." With respect to existence, I argue that McGinn's view that existence is a property that some objects have and other objects lack requires the property of existence to be fundamentally unlike ordinary qualitative properties. Moreover, it opens up a challenging skeptical problem: how do I know that I exist? With respect to modality, I argue that (...) McGinn's argument that quantificational analyses of modality in terms of possible worlds are inevitably circular does not apply to modal theorists who hold that the notion of an impossible world is incoherent.

Herein, I consider arguments resting on an appeal to a non-existent authority as a species of argument from authority, and ultimately show them to be reliant on arguments from analogy in their inferential force. Three sub-types of argument are discussed: from authorities as yet unborn, no longer living, or incapable of ever doing so. In each case it is shown that an element of arguing from analogy is required since there can be no direct evidence of any assertions of the (...) source. In conclusion, it is suggested that such steps of analogy are employed frequently in traditional arguments from authority. (shrink)

It is argued that just as there is a distinction between tensed and tenseless sentences so is there a distinction between worldly and unworldly sentences. This distinction has important implications for questions of possible non-existence, the nature of sortal concepts, such as man or set, and the different ways in which an object might exist.

The argument is an investigation of the philosophy of Austrian philosopher Alexius Meinong. There are three chapters. The first chapter argues that there are non-existent objects. It is argued that negative existential statements have a simple subject-predicate logical form. The conclusion follows from this premise, together with realist assumptions about truth and predication. Positive and negative existential statements have subject-predicate logical form, I argue, because; that is the grammatical form they appear to have, and the alternative analysis of their logical (...) form is unable to explain certain features of positive and negative existential statements. ;The second chapter presents Meinong's theory and explains his terminology. Meinong was primarily interested in the phenomenon of intentionality, and developed his own technical idiom. An assumption is a mental state, akin to judgment but without the element of conviction. It refers to a circumstance, which is a mind-independent arrangement of objects. Intending an object is a matter of assuming a circumstance. Two theses characterize Meinong's thought. The Principle of Independence: Objects can be in positive predicative circumstances, even when they are not in positive existential circumstances. And the Principle of Indifference: An object is equally adapted to entering into both positive and negative existential circumstances. ;The third chapter examines issues arising from charges that Meinong's theory is inconsistent. Meinong's theory is not inconsistent. Logical re-constructions of Meinong's theory, however, exploit primitive logical distinctions that lack a clear metaphysical justification. Meinong's technical notion of a modal moment is suited to the solution of difficulties Meinong was unaware of, and has been neglected by Meinong's other commentators. (shrink)

Two connected themes have been at the core of the old perplexity regarding thinking and speaking about non-existent objects. One involves a question of reference. Can we refer to non-existent objects without, thereby, recognizing, in some sense, non-existent entities as objects of reference? The other involves a question about existence. Is existence a property representable by a predicate in a logically adequate symbohsm? It is argued (1) that existence is not to be construed as an attribute represented (...) by a predicate, (2) that nonnaming names introduce problems, not solutions to problems, (3) that purported properties such as self-identical are specious, and (4) that the Russell property is also seen to be specious by our consideration of predication.

The theory of natural selection is a rich systematization of biological knowledge without a first principle. When formulations of a proposed principle of natural selection are examined carefully, each is seen to be exhaustively analyzable into a proposition about sources of fitness and a proposition about consequences of fitness. But whenever the fitness of an organic variety is well defined in a given biological situation, its sources are local contingencies together with the background of laws from disciplines other than the (...) theory of natural selection; and the consequences of fitness for the long range fate of organic varieties are essentially applications of probability theory. Hence there is no role and no need for a principle of the theory of natural selection, and any generalities that may hold in that theory are derivative rather than fundamental. (shrink)

Burkle examines various philosophical suggestions that God is not an existing reality. Hegel, Sartre, and Henry Dumery are selected as representative of the position Burkle calls "antitheism." What is common to all of the antitheists is that objective existence is denied to God, or that the category of existence itself is an ambiguous one when ascribed to God. Burkle argues that one cannot divorce the concept of human existence from a concept of the "other," or God, or (...) some notion of transcendence, of that which is beyond man. The author argues that neither Hegel, Sartre, or Dumery were capable of doing that. The solution to the problem Burkle finds in the philosophical constructions of Whitehead and Hartshorne. This book promises to be as important a theological work as Shubert Ogden's The Reality of God or John B. Cobb's Natural Theology.--W. A. J. (shrink)

Brentano's famous thesis of the Intentionality of the Mental was already formulated by Thomas Reid who used it in his campaign against the Locke-Berkeley-Hume Theory of Ideas. Apphed to the case of conceiving the thesis says that to conceive is to conceive something. This principle stands in apparent conflict with the common-sensical view, defended by Reid, that we can conceive what does not exist. Both principles, it is argued, are plausible and should be retained. The problem is how to resolve (...) the apparent contradiction. Reid's way out of the dilemma is clarified by contrasting it with less satisfactory solutions. (shrink)

This essay argues for the importance of developing theories of nonexistent objects. The grounds are utility and smoothness of logical theory. In the latter case a parallel with the theory of negative and imaginary numbers is exploited. The essay concludes with a counterexample to a general argument against the enterprise of developing theories of nonexistent objects, and outlining the foremost problem an adequate theory of nonexistent objects must solve.

Can non-existence be perceived? While the answer may seem obviously negative, proving this is not straightforward. This article extracts several arguments for the claim that "non-existence cannot be an object of perception" from the reasoning provided by Saṃghabhadra regarding "non-existence cannot be an object of *buddhi. Two main arguments are reconstructed and both are reductio ad absurdum. The first suggests that if any non-existence could be perceived, all instances of non-existence would be perceived. Combined with (...) Saṃghabhadra's causal theory of perception, this implies that one perception could perceive all instances of non-existence. The second posits that if non-existence were an object of perception, it would result in no perception occurring at all. As a problem-oriented study, this article reconstructs and evaluates Saṃghabhadra's arguments, demonstrating that "non-existence cannot be perceived" is not as easily proved as it appears, and Saṃghabhadra’s insightful arguments, though vulnerable to challenges, hold promise for further defense.

One of the most widespread claims combining epistemology and metaphysics in post-Avicennian Islamic philosophy was that every object of thought is real. In Muʿtazilite reading, it was endorsed due to a theory of knowledge which states that knowledge is a connection or relation between the knower and the object known. Avicennists accepted it due to the rule that in a proposition “s is p” if p is something positive s has to be positive and real too. Hence, insofar as one (...) can conceptually distinguish between two non-existent items, they have to be real. In this article, the author presents significant consequences of this theory: the acceptance and denial of non-existent yet real extramental objects; the concept of mental existence as an alternative solution; the conceivability of paraconsistent ideas and their reality or reducibility to some real objects.

I shall defend in this paper the thesis that, if there are irreducible powers such as the power to produce a certain object (generative powers), then there are objects that do not exist and they are part of the fundamental level of the universe. Thus, generative powers come together with Meinongianism. After having clarified my argument, I shall examine and criticize Armstrong (1997)’s attempt to reduce powers to other sorts of entities. Finally, I shall deal with five accounts of generative (...) powers that are somehow alternative to Meinongianism and with some (more general) miscellaneous concerns about the truth of this doctrine.

When Husserl speaks of the so-called ‘transcendental reduction’ or ‘phenomenological epochē’ many believe that he is eschewing the question of truth or existence. Two reasons are given for this: First, Husserl explicitly states that when we perform the reduction, we should no longer naively ‘accept [the world] as it presents itself to me as factually existing’ (Id I §30, p. 53) and should suspend our judgement with regard to ‘the positing of its actual being’ (Id I §88, p. 182). (...) Second, Husserl seems to have no problem in referring to an ‘object’ of thought even when we refer to non-existent, hallucinatory or indeed impossible objects. This seems to suggest that he is not interested in the question whether or not there is a corresponding ‘ordinary’ object. The paper seeks to question this and will show that his inquiry never loses sight of the questions of truth and existence but rather brings them into the foreground. (shrink)

It is probably true to say that the majority of philosophers have considered the universe to be mental. If the universe is really mental, it follows that matter cannot be quite real, and many philosophers have in fact brought forward cogent reasons for regarding matter as in some sense illusory. Those who hold this view are called Idealists. Idealism has historically assumed a number of different forms, between some of which there is little in common, but all forms of Idealism (...) agree in maintaining that objects, such as chairs and tables, of which common sense believes the external world to exist, are not material.

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)
