It is a commonplace of constructivist thought that a claim that an object of a certain kind exists is to be backed by an explicit display or exhibition of an object that is manifestly of that kind. Let us refer to this requirement as the exhibition condition. The main objective of this essay is to examine this requirement and to arrive at a better understanding of its epistemic character and the role that it plays in the two main constructivist philosophies (...) of this century---the intuitionist programme of Brouwer and Weyl, and the finitist programme of Hilbert.

Controversies, i.e., multiple theory confrontations, may have a strong impact on the development of science. By an analysis of the so-called resonance controversy in chemistry the view that controversies and their resolution differ considerably from the process of theory succession is defended. It is argued that controversies are symptomatic of foundational problems, produce theory-scattering or domain-splitting, and induce ontological shifts. An explication is given of the role of existence claims and the applicability of Ockham's Razor in the resolution (...) of controversies. The requirement of a realistic interpretation of theories at all times, as defended by some philosophers, is criticised. (shrink)

Some contemporary theologically inclined epistemologists, the reformed epistemologists, have attempted to show that belief in God is rational by appealing directly to a special kind of experience. To strengthen the appeal to this particular, and admittedly peculiar, type of experience these venture to draw a parallel between such experiences and normal perceptual experiences in order to show that, by parity of reasoning, if beliefs formed on the basis of the later are taken to be justified and rational to hold, then (...) beliefs formed on the basis of the former should also be regarded as justified and rational to hold. Such appeals to religious experience have been discussed and/or made by Robert Pargetter, Alvin Plantinga and William Alston and they claim that they provide sufficient warrant for religious beliefs, specifically for the belief that God exists. The main critical issue that will be raised here concerns the coherence of this notion of religious experience itself and whether such appeals to religious experience really provide justification for belief in the existence of God.<br><br>.

Some believe that all arguments make an implicit “inference claim” that the conclusion is inferable from the premises (e.g., Bermejo-Luque, Grennan, the Groarkes, Hitchcock, Scriven). I try to show that this is confused. An act of arguing arises because an inference can be attributed to us, not a meta-level “inference claim” that would make the argument self-referential and regressive. I develop six (other) possible explanations of the popularity of the doctrine that similarly identify confusions.

As a result of the developments in science and technology, humanity began to experience a digital transformation after the 19th century. With this digital transformation, it is seen that a serious change has occurred in human beings biologically, socially, and, more specifically, religiously. One could say that different trends have emerged at many points where human relations, the relationship of the human with the environment and with God are also affected. Among the most comprehensive and prominent of these trends is (...) transhumanism because of its aims for humanity and the world. Transhumanism, which views technology as the main point of reference for the future of humanity, is also considered a cultural, social, and ideological human movement with its statements intended for society. It considers immortality as a goal, along with such claims as improving welfare, extending human life, and wiping out diseases by using technology in every aspect of human life. Transhumanists, who claim that they can achieve immortality thanks to technology, argue that this will happen in two ways. The first is biological immortality. It will be achieved by eliminating all kinds of biological factors that lead to humans aging and death. The second is digital or virtual immortality, which is achieved by transferring human consciousness from the biological body to computer interfaces and installing it in any desired entity. This perspective must be critically examined as it can be considered an attempt to challenge death, which is the basic doctrine of classical religions. In the present study, human immortality, considered the most important claim made by transhumanists, is criticized within kalām, Islamic theology. Of course, transhumanists’ account of human immortality is impossible, according to kalām. It can be said that transhumanists view of immortal human can be considered in the category of created beings, which is defined in kalām as "the being created later and needs another being in order to exist and to continue its existence". Given that transhumanists base the idea of the immortal being upon biological healing or digital transmission, it is clear that both types of beings need someone else. Therefore, one could say that it would be more reasonable to define transhumanists’ notion of immortality as the act of prolonging human life. It is because the life of immortal beings, accepted as biological or digital entities, is shaped by many factors. If these factors disappear, so does the being. On the other hand, the attribute of immortality, which belongs to the eternal being only, according to kalām, must come from itself without needing any other being. Therefore, the notion of immortal being suggested by the transhumanists must be reexamined within kalām and be redefined as the extension of life. The redefined immortality as the extension of life hardly poses kalāmī (or theological) problems. In fact, Islam encourages using all types of tools and equipment to enable humans to have a healthy and blissful life. (shrink)

I argue that thinking of existence questions as deep questions to be resolved by a distinctively philosophical discipline of ontology is misguided. I begin by examining how to understand the truth-conditions of existence claims, by way of understanding the rules of use for ‘exists’ and for general noun terms. This yields a straightforward method for resolving existence questions by a combination of conceptual analysis and empirical enquiry. It also provides a blueprint for arguing against most common (...) proposals for uniform substantive ‘criteria of existence’, whether they involve mind-independence, possession of causal powers, observability, etc., and thus for showing that many arguments for denying entities (numbers, ordinary objects, fictional characters, propositions…) on grounds of their failure to meet one or more of these proposed existence criteria are mistaken.

Richard Swinburne presents a substantially rewritten and updated edition of his most celebrated book. No other work has made a more powerful case for the probability of the existence of God. Swinburne gives a rigorous and penetrating analysis of the most important arguments for theism: the cosmological argument; arguments from the existence of laws of nature and the 'fine-tuning' of the universe; from the occurrence of consciousness and moral awareness; and from miracles and religious experience. He claims (...) that while none of these arguments are deductively valid, they do give inductive support to theism and that, even when the argument from evil is weighed against them, taken together they offer good grounds to support the probability that there is a God. The overall structure of the discussion and its conclusion have been retained for this new edition, but much has been changed in order to strengthen the argumentation and to take account of Swinburne's subsequent work on the nature of consciousness and the problem of evil, and of the latest philosophical and scientific writing, especially in respect of the laws of nature and the argument from fine-tuning. This is now the definitive version of a classic in the philosophy of religion. (shrink)

Nieuwenhuizen argued that there exists some “contextuality loophole” in Bell’s theorem. This claim is unjustified. In Bell’s theorem non-contextuality is not presupposed but derived from Einstein causality using the EPR argument.

Semantic externalism in the style of McDowell and Evans faces a puzzle formulated by Pryor: to explain that a sentence such as 'Jack exists' is only a posteriori knowable, despite being logically entailed by the seemingly logical truth 'Jack is self-identical', and hence being itself a logical truth and therefore a priori knowable. Free logics can dissolve the puzzle. Moreover, Pryor has argued that the existentially hedged 'If Jack exists, then Jack is self-identical', when properly formalised, is a logical truth (...) in a system of neutral free logic and therefore a priori knowable, while it does not entail that Jack exists. The latter holds also for negative free logic. In response, Yeakel has argued that on any system of neutral free logic existence hedges will either entail some unwanted existence claims or they will not entail some wanted existence claims. The dilemma also holds for any non-positive free logic. It will be shown that the extension of one of the systems of neutral free logic with a truth operator escapes Yeakel's dilemma, whereas no other non-positive free logic when extended with the truth operator does the same (or it breaks quantifier exchangeability). (shrink)

I argue that neutral free logic and existence hedging are incompatible. Primarily, I respond to proposals by James Pryor intended to reconcile the two. Consideration of those proposals will reveal that on any neutral free logic either some existence hedges will entail some undesired existence claims, or they will not entail some desired existence claims.

International Journal of Machine Consciousness, Volume 06, Issue 02, Page 141-161, December 2014. This paper follows directly from an earlier paper where we discussed the requirements for an artifact to be a moral agent and concluded that the artifactual question is ultimately a red herring. As before, we take moral agency to be that condition in which an agent can appropriately be held responsible for her actions and their consequences. We set a number of stringent conditions on moral agency. A (...) moral agent must be embedded in a cultural and specifically moral context and embodied in a suitable physical form. It must be, in some substantive sense, alive. It must exhibit self-conscious awareness. It must exhibit sophisticated conceptual abilities, going well beyond what the likely majority of conceptual agents possess: not least that it must possess a well-developed moral space of reasons. Finally, it must be able to communicate its moral agency through some system of signs: A "private" moral world is not enough. After reviewing these conditions and pouring cold water on recent claims for having achieved "minimal" machine consciousness, we turn our attention to a number of existing and, in some cases, commonplace artifacts that lack moral agency yet nevertheless require one to take a moral stance toward them, as if they were moral agents. Finally, we address another class of agents raising a related set of issues: autonomous military robots. (shrink)

Analytic philosophy of existence in the 20th century and beyond has been dominated by two central claims. One is that existence is instantiation. The other is that there are no modes of existence. This article attempts to refute both claims.

This paper investigates the connection between two recent trends in philosophy: higher-orderism and conceptual engineering. Higher-orderists use higher-order quantifiers (in particular quantifiers binding variables that occupy the syntactic positions of predicates) to express certain key metaphysical doctrines, such as the claim that there are properties. I argue that, on a natural construal, the higher-orderist approach involves an engineering project concerning, among others, the concept of existence. I distinguish between a modest construal of this project, on which it aims at (...) engineering higher-order analogues of the familiar notion of first-order existence, and an ambitious construal, on which it additionally aims at engineering a broadened notion of existence that subsumes first-order and higher-order existence. After identifying a substantial problem for the ambitious project, I investigate a possible response which is based on adopting a cumulative type theory as the background higher-order logic. While effective against the problem at hand, this strategy turns out to undermine a major reason to embrace higher-orderism in the first place, namely the idea that higher-orderism dissolves a range of otherwise intractable debates in metaphysics. Higher-orderists are therefore best advised to pursue their engineering project on the modest variant and against the background of standard type theory. (shrink)

Existence Value has become an increasingly important concept as the use of cost benefit analysis has spread from traditional applications to attempts to place monetary value on, for instance, a rare wetland habitat. Environmental economists have generally accepted the tensions arising in the existence value concept from the range of recent applications, but it is argued here that their various attempts to resolve the difficulties have largely failed. Critics from outside economics, on the other hand, typically claim that (...) the very notion of existence value as understood in economics is flawed, and urge its abandonment altogether. This paper suggests instead a fundamental redefinition of existence value, which, it is argued, (i) explains a number of diverse problems posed by the usual meaning of the term in economics; (ii) does not strain the intentions of respondents to ' willingness-to-pay' surveys; (iii) is consistent with a more realistic model of rational choice in environmental decision-making; and (iv) is sensitive to criticisms from environmental ethics.2.

This paper develops and defends a deflationary analysis of existence claims involving psychiatric disorders. According to this analysis, a given psychiatric disorder exists if, and only if, there are people who have the disorder. The implications of this analysis are spelled out for our views of nosological decision making, and for the relationship between claims about the existence of psychiatric disorders and claims about their reality. A pragmatic view of psychiatric nosology is defended and it (...) is argued that worries about the “reality” of any given disorder have to be distinguished clearly from questions about its existence.

The efforts to prove God's existence in the history of thought have been one of the fundamental problems of philosophy and theology, and even the most important one. The evidences put furword to prove the existence of God constitute the center of philosophy of religion’s problems not only philosophy of religion, but also the disciplines such as theology-kalam and Islamic philosophy are also seriously concerned. When we look at the history of philosophy, it is clear that almost all (...) philosophers are interested in the evidence in favour of and against the existence of God. Especially in recent times, religious experience has often been regarded as evidence of the existence of God. Studies in the field of religious and mystical experience have put forward many arguments concerning the use of religious experience as evidence. However, this study has been limited to experience of sense and pure consciousness claims rather than examining all of these arguments. In this study firstly, the analogy between experience of sense and religious experience will be deal with, and then claims that conciousness can be emptied by a number of methods which are defended by mystics. In addition, it will be tried to defend the opinion that the mystical experiences which are the common point of the two approaches are valid. The main emphasis of the article will be that these arguments can be used as evidence for the existence of God.Summary: Religious experience - which has not been considered as one of the classical evidences regarding the existence of God before being popular by recent studies – is started to be called one of the arguments. The most important reason for not arguing religious experience among the evidences of God’s existence is that it is a personal experience and therefore contains subjective perspectives. However, many researchers, who refuse to accept the criticism raised against religious experience with restricting to subjectivity, emphasized the importance of religious experience by highlighting the objective aspects of such experiences. This emphasis was not only on its significance, but also on the fact that it had a cognitive feature and thus it could provide evidence for the existence of God. The argument of religious experience is generally defined as an effort for demonstrating to existence of God with reference to several feelings such as spiritual experiences of human in face of creator and sacred Being, encounter with God, uniting, and annihilating selfness in Him. The emergence of such efforts, especially after the XVIIIth century, indicates that the history of the evidence does not go back much earlier. However, even if notas evidence, it is possible to extend the traces of religious and mystical experience to the history of religions such as Buddhism and Hinduism. Considering a great amount of the previous literature focused on religious experience in the West, It is easily seen that such research is still new. The main purpose in addressing such a controversial issue is to make the argument on the religious experience more current and to show whether the religious experience would be able to use as evidence for the existence of God.First title of this study comprises many different claims such as Walter T. Stace’s The Argument from Unanimity Richard Swinburne’s The Principle of Credulity, William P. Alston’s Perceiving God, John Hick’s Experience-as. However, instead of briefly giving out very different claims, the study chooses to focus on two arguments which are less discussed and can be given in more detail. The first is the argument based on the analogy between the religious experience and the sense experience. The fundamental point of this argument is sense experience. With reference to the similarities between the sense experience and the religious experience, it can be argued that religious experience is also cognitive and may function as an evidence for the existence of God. In other words, being perceptual and noetic, namely cognitive, of sense experience is addressed as a similar side of religious experience. Whether it is imaginary or real, eventually, it is necessary for an experience to have an object and being experience of something. Therefore, the religious experience includes the perception of a Transcendent Being that is beyond and in excess of the individual who experiences. Perception of the sense experience will definitely be different from the perception of religious experience. Researchers who think that the five sense organs do not run the perception of Sacred Beings, identified broader and various meanings for the perception. Thereby, in this approach, where the semantic field of perception is expanded, it was contended that human beings were able to perceive the transcendent, eternal, and unlimited God, and this can be explained in the epistemological sense. In order to use religious experiences as an evidence for the existence of God, it is necessary to determine whether such experiences are caused by God rather than something else. This raises the issue of the validity of religious experience. The researchers in this area have propounded various criteria to identify whether religious experience is existed or not. Experiences, which do not meet the criteria, are not considered existed even if they claim to be religious experience.The second is the argument that discusses whether it is possible to suggest an evidence for the existence of God by utilizing pure consciousness events. In general, this argument claims that the consciousness gets clear, and thus, mystic or Sufi experiences the Divine One with pure consciousness by discharging consciousness from all sensual contents and removing it from secular desire and wishes. The argument, which claims the experience of Divine One is direct, therefore uninterpretable, and experienced by pure consciousness, believes clearing the consciousness of mystics from sensual qualities such as seeing, hearing, and tasting. It is stated that it is possible for mystics to empty their sensory images and get rid of them, and thus, their desires and wishes could be lost. Especially, the thinkers who are connected with the philosophy of perennialism and defend this approach, thought that people, who have distinct religion, culture, and beliefs in different parts of the world and in various time periods, had the same experience and considered such experiences were universal by suggesting that this similarity could be called as common essence.Even though the claim which offers that the events of pure consciousness are the same everywhere have been criticized in many respects, the advocates of this approach have argued that the experience has the common essence, but the interpretation is different. This relationship, which was tried to be established between experience and commentary, caused a lot of work for both the thinkers who put forward the claims of pure consciousness and the researchers who opposed it. However, examining the relationship between experience and interpretation requires serious studies in socio-psychological, cultural and religious fields. Therefore, in order not to exceed the limits of the article, the relationship between experience and interpretation is briefly mentioned.While discussing two arguments, the main claims of the arguments were addressed, and the criticisms directed to this argument were not discussed as much as possible. However, some fundamental criticisms have been mentioned shortly for a better understanding of the discussion. Since such western-oriented claims mostly were deployed in a western context, the study excluded the comparison of the claims across different cultures. (shrink)

A central dispute in social ontology concerns the existence of group minds and actions. I argue that some authors in this dispute rely on rival views of existence without sufficiently acknowledging this divergence. I proceed in three steps in arguing for this claim. First, I define the phenomenon as an implicit higher-order disagreement by drawing on an analysis of verbal disputes. Second, I distinguish two theories of existence—the theory-commitments view and the truthmaker view—in both their eliminativist and (...) their constructivist variants. Third, I examine individual contributions to the dispute about the existence of group minds and actions to argue that these contributions have an implicit higher-order disagreement. This paper serves two purposes. First, it is a study to apply recent advances in meta-ontology. Second, it contributes to the debate on social ontology by illustrating how meta-ontology matters for social ontology. (shrink)

Particular persons have claims against being made worse off than they could have been. The literature, however, has focused primarily on only two-option cases; yet, these cases fail to capture all of the morally relevant factors, especially when a person’s existence is in question. This paper explores how to assess claims in multiple-option choice sets. We scrutinize the only extant proposal, offered by Michael Otsuka, which we call the Weakening View. In light of its problems, we develop (...) an alternative: the Combining View. The Weakening View holds that a person’s claim against a loss of well-being relative to one distribution is weakened by the availability of further alternatives relative to which the person gains well-being. By contrast, our view holds that a person has an overall claim for or against a certain distribution relative to the whole option set, where overall claims are second-order functions of the different pairwise claims. Finally, we defend the Combining View by exploring its implications for the impact of a person’s possible non-existence on their overall claims, and we develop a proposal for how the number of distributions relative to which a person gains or loses welfare influences the strength of their overall claims.

The mere fact that ontological debates are possible requires us to address the question, what is it to claim that a certain entity or kind of entity exists—in other words, what do we do when we make an existence-claim? I develop and defend one candidate answer to this question, namely that to make an existence-claim with regard to Fs is to claim that we can refer to Fs. I show how this theory can fulfil the most important explanatory (...) desiderata for a theory of existence; I also defend it against the charges of illegitimate ‘semantic ascent’ and of making existence counterfactually dependent on human linguistic ability.

Timothy Williamson has argued for the radical conclusion that everything necessarily exists. In this paper, I assume that the conclusion of Williamson’s argument is more incredible than the denial of his premises. Under the assumption that Williamson is mistaken, I argue for the claim that there are some structured propositions which have constituents that might not have existed. If those constituents had not existed, then the propositions would have had an unfilled role; they would have been gappy. This gappy propositions (...) view allows for a plausible response to Williamson’s argument. Additionally, a slight variant of the gappy propositions view allows for plausible defense of Linguistic Ersatzism from the problem of contingent non-existents (also known as the problem of aliens).

This essay considers Kant’s theory of modality in light of a debate in contemporary modal metaphysics and modal logic concerning the Barcan formulas. The comparison provides a new and fruitful perspective on Kant’s complex and sometimes confusing claims about possibility and necessity. Two central Kantian principles provide the starting point for the comparison: that the possible must be grounded in the actual and that existence is not a real predicate. Both are shown to be intimately connected to the (...) Barcan formulas, and Kant’s views on what he distinguishes as three different kinds of modality are then considered in light of this connection.

one of kant's most famous claims is his dictum about existence. In the course of his criticism of the ontological argument, he writes:Being is obviously not a real predicate, i.e., a concept of something that could be added to the concept of a thing.One reason why this passage is so famous is that many people think that it anticipates a discovery about the logical form of existence claims that was later central for the development of analytic (...) philosophy and its project of overcoming metaphysical confusions by logical analysis. There are two prominent interpretations that read Kant's dictum along these lines. The first, and by far most popular, interprets Kant as holding a proto-Fregean view about existence.2... (shrink)

We initially characterize what we’ll call existence problems as problems where there is evidence that a putative entity exists and this evidence is not easily dismissed; however, the evidence is not adequate to justify the claim that the entity exists, and in particular the entity hasn’t been detected. The putative entity is elusive. We then offer a strategy for determining whether an existence problem is philosophical or scientific. According to this strategy (1) existence problems are characterized in (...) terms of causal roles, and (2) these problems are categorized as scientific or philosophical on the basis of the epistemic context of putative realizers. We argue that the first step of the strategy is necessary to avoid begging the question with regard to categorization of existence problems, and the second step categorizes existence problems on the basis of a distinction between two ways in which an entity can be elusive. This distinction between kinds of elusiveness takes as background a standard account of inference to the best explanation. Applying this strategy, we argue that the existence of a multiverse is a scientific problem. (shrink)

This book offers a radically new account of the development and structure of the central arguments of Kant's Critique of Pure Reason: the defense of the objective validity of such categories as substance, causation, and independent existence. Paul Guyer makes far more extensive use than any other commentator of historical materials from the years leading up to the publication of the Critique and surrounding its revision, and he shows that the work which has come down to us is the (...) result of some striking and only partially resolved theoretical tensions. Kant had originally intended to demonstrate the validity of the categories by exploiting what he called 'analogies of appearance' between the structure of self-knowledge and our knowledge of objects. The idea of a separate 'transcendental deduction', independent from the analysis of the necessary conditions of empirical judgements, arose only shortly before publication of the Critique in 1781, and distorted much of Kant's original inspiration. Part of what led Kant to present this deduction separately was his invention of a new pattern of argument - very different from the 'transcendental arguments' attributed by recent interpreters to Kant - depending on initial claims to necessary truth.

The currently standard philosophical conception of existence makes a connection between three things: certain ways of talking about existence and being in natural language; certain natural language idioms of quantification; and the formal representation of these in logical languages. Thus a claim like ‘Prime numbers exist’ is treated as equivalent to ‘There is at least one prime number’ and this is in turn equivalent to ‘Some thing is a prime number’. The verb ‘exist’, the verb phrase ‘there is’ (...) and the quantifier ‘some’ are treated as all playing similar roles, and these roles are made explicit in the standard common formalization of all three sentences by a single formula of first-order logic: ‘(∃ x )[P( x ) & N( x )]’, where ‘P( x )’ abbreviates ‘ x is prime’ and ‘N( x )’ abbreviates ‘ x is a number’. The logical quantifier ‘∃’ accordingly symbolizes in context the role played by the English words ‘exists’, ‘some’ and ‘there is’. (shrink)

N eventually hits on an appealing interpretation of the slogan that C can neither undermine nor accommodate, and uses it to interpret the second slogan as well. (shrink)

Yet, he also says that it is philosophically indeterminate which criterion for what exists is correct. Nominalism is the view that certain objects ( i.e ., abstract objects) do not exist, and not the view that it is philosophically indeterminate whether or not they do.

In this paper, I examine Kant's famous objection to the ontological argument: existence is not a determination. Previous commentators have not adequately explained what this claim means, how it undermines the ontological argument, or how Kant argues for it. I argue that the claim that existence is not a determination means that it is not possible for there to be non-existent objects; necessarily, there are only existent objects. I argue further that Kant's target is not merely ontological arguments (...) as such but the larger ‘ontotheist’ metaphysics they presuppose: the view that God necessarily exists in virtue of his essence being contained in, or logically entailed by, his essence. I show that the ontotheist explanation of divine necessity requires the assumption that existence is a determination, and I show that Descartes and Leibniz are implicitly committed to this in their published versions of the ontological argument. I consider the philosophical motivations for the claim that existence is a determination and then I examine Kant's arguments in the Critique of Pure Reason against it. (shrink)

Sceptics about substantial disputes in ontology often argue that when two philosophers seem to disagree on a quantified claim, they are actually equivocating on the notion of existence that they are using. When temporal elements play a central role, as in the debate between presentists and eternalists, the hypothesis of an equivocation with respect to existence acquires more plausibility. However, the anti-sceptic can still argue that this hypothesis is unjustified.

Linnebo in 2018 argues that abstract objects like numbers are “thin” because they are only required to be referents of singular terms in abstraction principles, such as Hume's principle. As the specification of existence claims made by analytic truths (the abstraction principles), their existence does not make any substantial demands of the world; however, as Linnebo notes, there is a potential counter-argument concerning infinite regress against introducing objects this way. Against this, he argues that vicious regress is (...) avoided in the account of arithmetic based on Hume's principle because we are specifying numbers in terms of the concept of equinumerosity, or its ordinal equivalent. But far from being only a matter for philosophy, this implies a distinct empirical prediction: in cognitive development, the principle of equinumerosity is primary to number concepts. However, by analysing and expanding on the bootstrapping theory of Carey in 2009, I argue in this paper that there are good reasons to think that the development could be the other way around: possessing numerosity concepts may precede grasping the principle of equinumerosity. I propose that this analysis of early numerical cognition can also help us understand what numbers as thin objects are like, moving away from Platonist interpretations. (shrink)

In his book Kant and the Problem of Self-Knowledge (New York, Abingdon: Routledge 2019, 214 pages) Luca Forgione argues that the semantic, epistemic and metaphysical analysis of Kant’s theory of self-knowledge is possible within the frame of a merely formal understanding of ‘I’. Although the author shows that for Kant self-knowledge is in fact knowledge of a formal thinking subject, there remains the difficulty that the formal analysis of self-knowledge entails the existence claim about the transcendental apperception. This claim (...) is incompatible, I argue, with Kant’s theory of the analytic and synthetic unity of apperception. (shrink)

In this paper, I will defend the claim that there are three existence properties: the second-order property of being instantiated, a substantive first-order property (or better a group of such properties) and a formal, hence universal, first-order property. I will first try to show what these properties are and why we need all of them for ontological purposes. Moreover, I will try to show why a Meinong-like option that positively endorses both the former and the latter first-order property is (...) the correct view in ontology. Finally, I will add some methodological remarks as to why this debate has to be articulated from the point of view of reality, i.e., by speaking of properties, rather than from the point of view of language, i.e., by speaking of predicates (for such properties).

Originally published in 1992. The history of Western philosophy can be seen as a battle between those that insist that the "physical universe" exists and those would claim that there is a much larger "world" which contains atemporal and nonspatial things as well. The central part of this book, and the battle, concerns the existence of universals. Starting with the mediaeval definition of the issue found in Porphry and Boethius, the author then considers modern and contemporary versions of the (...) battle. He concludes that what is at stake between naturalists and ontologists is the existence and nature of a number of important categories, like structures, relations, sets, numbers and so on. (shrink)

Reference and Existence, Saul Kripke's John Locke Lectures for 1973, can be read as a sequel to his classic Naming and Necessity. It confronts important issues left open in that work -- among them, the semantics of proper names and natural kind terms as they occur in fiction and in myth; negative existential statements; the ontology of fiction and myth. In treating these questions, he makes a number of methodological observations that go beyond the framework of his earlier book (...) -- including the striking claim that fiction cannot provide a test for theories of reference and naming. In addition, these lectures provide a glimpse into the transition to the pragmatics of singular reference that dominated his influential paper, " Speaker's Reference and Semantic Reference " -- a paper that helped reorient linguistic and philosophical semantics. Some of the themes have been worked out in later writings by other philosophers -- many influenced by typescripts of the lectures in circulation -- but none have approached the careful, systematic treatment provided here. The virtuosity of Naming and Necessity -- the colloquial ease of the tone, the dazzling, on-the-spot formulations, the logical structure of the overall view gradually emerging over the course of the lectures -- is on display here as well.

This paper asks: Is the quantifier variantist committed to metaphysical vagueness? My investigation of this question goes via a study of vague existence. I’ll argue that the quantifier variantist is committed to vague existence and that the vague existence posited by the variantist requires a puzzling sort of metaphysical vagueness. Specifically, I distinguish between (what I call) positive and negative metaphysical vagueness. Positive metaphysical vagueness is (roughly) the claim that there is vagueness in the world; negative metaphysical (...) vagueness is (roughly) the claim that there is vagueness that is not in our language or thought. I’ll argue that the quantifier variantist’s commitment to vague existence comes with positive metaphysical vagueness -- even if it doesn't require negative metaphysical vagueness. (shrink)

Abstract:The straightforward normative importance of emergencies suggests that empirically engaged political theorists and philosophers should study them. Indeed, many have done so. In this essay, however, I argue that scholars interested in the political and/or moral dimensions of large-scale emergencies should shift their focus from emergencies to emergency claims. Building on Michael Saward’s model of a “representative claim,” I develop an account of an emergency claim as a claim that a particular (kind of) situation is an emergency, made by (...) particular actors against particular background conditions to particular audiences, which in turn accept, ignore, or reject that claim. Emergency politics, in turn, consists of many different actors making and not making, accepting, and rejecting, a wide range of overlapping and competing emergency claims. I argue that scholars should shift their focus to emergency claims because doing so helps us see the fraught implications of emergency politics for marginalized groups. I examine three such implications: emergency claims are often “Janus-faced,” meaning that they function simultaneously as “weapons of the weak” and weapons of the strong; they are often regressive, including by discriminating against victims of chronic bad situations, and they often perpetuate and exacerbate existing social hierarchies. Noticing these troubling features of emergency politics raises a question that I do not address here: What might plausible alternatives to emergency politics look like? (shrink)

The paper argues that promise rights presuppose independently existing (if not pre-existing) claims. The argument relies on the Bifurcation Thesis, according to which all claims, and all rights, can be exhaustively divided into two categories: capacity based and exercise based.

Timothy Williamson offers a proof of the counterintuitive claim that, if an object exists, then it exists necessarily. David Wiggins argues that this result reveals the philosophical disadvantage of a first level (or ‘ticking over’) view of the very ‘exists’ and the advantage of the second level account offered by Frege and Russell. The author seeks to show how, using an idea of G. Evans but without the use of the resources of ‘free logic’, all occurrences of ‘exist’, including its (...) occurrence in true, negative existential, singular statements, can be accommodated to the Frege–Russell view and accorded the intuitively required modal status.

Alessandro Torza argues that Ted Sider’s Lewisian argument against vague existence is insufficient to rule out the possibility of what he calls ‘super-vague existence’, that is the idea that existence is higher-order vague, for all orders. In this chapter it is argued that the possibility of super-vague existence is ineffective against the conclusion of Sider’s argument since super-vague existence cannot be consistently claimed to be a kind of linguistic vagueness. Torza’s idea of super-vague existence (...) seems to be better suited to model vague existence under the assumption that vague existence is instead a form of ontic indeterminacy, contra what Ted Sider and David Lewis assume.

Early in Being and Time Heidegger announces that the primary concept by means of which he aims to understand Dasein is the concept to which he gives the name ‘existence.’ But what is existence? Existence is, roughly, that feature of Dasein that its self-understanding is constitutive of its being what or who it is. In an important sense, this concept embodies Heidegger’s existentialism. At the center of existentialism lies the claim that humans are given their content neither (...) by an ahistorical, transcultural essence, nor by nature. Rather, Dasein itself determines this content in its act of self-understanding. Kierkegaard expressed this in his famous formulation that “The self is that which relates itself to itself;” Ortega in his catchy phrase, “Man has no nature;” and Sartre in his notorious proposition, “Existence comes before essence.” All of these dicta articulate the same idea.

In this article several justifications of what I call ‘the claim from adoption’ are examined. The claim from adoption is that, instead of expending resources on bringing new children into the world using reproductive technology and then caring for these children, we ought to devote these resources to the adoption and care of existing destitute children.Arguments trading on the idea that resources should be directed to adoption instead of assisted reproduction because already existing people can benefit from such a use (...) of resources whereas we cannot benefit individuals by bringing them into existence are rejected. It is then argued that a utilitarian argument proposed by Christian Munthe that supports the claim from adoption in some situations should be rejected because the support it offers does not extend to certain situations in which it seems morally obvious that resources should be expended on adoption rather than assisted reproduction. A version of the Priority View improves upon Munthe’s utilitarianism by supporting the claim from adoption in the cases in which Munthe’s argument failed. Some allegedly counterintuitive implications of the Priority View are then discussed, and it is concluded that the Priority View is more plausible than utilitarianism.n a concluding section on policy issues it is argued that, even though the claim from adoption can be justified in a variety of situations, it does not follow that, in these situations, governments should direct resources away from assisted reproduction and towards adoption.

This paper addresses the ontological status of the ontological categories as defended within E.J. Lowe’s four-category ontology (kinds, objects, properties/relations, and modes). I consider the arguments in Griffith (2015. “Do Ontological Categories Exist?” Metaphysica 16 (1):25–35) against Lowe’s claim that ontological categories do not exist, and argue that Griffith’s objections to Lowe do not work once we fully take advantage of ontological resources available within Lowe’s four-category ontology. I then argue that the claim that ontological categories do not exist has (...) no undesirable consequences for Lowe’s brand of realism. (shrink)

Hilbert’s choice operators τ and ε, when added to intuitionistic logic, strengthen it. In the presence of certain extensionality axioms they produce classical logic, while in the presence of weaker decidability conditions for terms they produce various superintuitionistic intermediate logics. In this thesis, I argue that there are important philosophical lessons to be learned from these results. To make the case, I begin with a historical discussion situating the development of Hilbert’s operators in relation to his evolving program in the (...) foundations of mathematics and in relation to philosophical motivations leading to the development of intuitionistic logic. This sets the stage for a brief description of the relevant part of Dummett’s program to recast debates in metaphysics, and in particular disputes about realism and anti-realism, as closely intertwined with issues in philosophical logic, with the acceptance of classical logic for a domain reflecting a commitment to realism for that domain. Then I review extant results about what is provable and what is not when one adds epsilon to intuitionistic logic, largely due to Bell and DeVidi, and I give several new proofs of intermediate logics from intuitionistic logic+ε without identity. With all this in hand, I turn to a discussion of the philosophical significance of choice operators. Among the conclusions I defend are that these results provide a finer-grained basis for Dummett’s contention that commitment to classically valid but intuitionistically invalid principles reflect metaphysical commitments by showing those principles to be derivable from certain existence assumptions; that Dummett’s framework is improved by these results as they show that questions of realism and anti-realism are not an “all or nothing” matter, but that there are plausibly metaphysical stances between the poles of anti-realism and realism, because different sorts of ontological assumptions yield intermediate rather than classical logic; and that these intermediate positions between classical and intuitionistic logic link up in interesting ways with our intuitions about issues of objectivity and reality, and do so usefully by linking to questions around intriguing everyday concepts such as “is smart,” which I suggest involve a number of distinct dimensions which might themselves be objective, but because of their multivalent structure are themselves intermediate between being objective and not. Finally, I discuss the implications of these results for ongoing debates about the status of arbitrary and ideal objects in the foundations of logic, showing among other things that much of the discussion is flawed because it does not recognize the degree to which the claims being made depend on the presumption that one is working with a very strong logic.

The question ''Was 'existence' ever a predicate?" in a way already suggests its own answer, that this is really the wrong question to ask, because 'existence' has always been a predicate. Even those, such as Kant, who supposedly opposed this view, in fact held it. They merely denied that 'existence' is a "normal" first-order predicate. Not only Kant, but also Bolzano, Frege and Russell claimed that it is a second-order predicate. There is substantive disagreement between Kant and (...) Bolzano on the one hand and Frege and Russell on the other over two issues: the former claim that this second-order predicate apphes to no concept analytically and that it can be properly ascribed to a singular concept, whereas the latter deny both of these claims.
