Since last year, major initiatives have been undertaken by the chair of theoretical philosophy at the University of Tübingen in order to enhance the reception of analytic metaphysics in the European landscape. Here we review the 2013 summer workshop, intended to be the first of an annual series, on “Existence, Truth and Fundamentality”, the invited speakers being Graham Priest (Melbourne), Stephan Leuenberger (Glasgow), Dan López de Sa (Barcelona), Francesco Berto (Aberdeen), Friederike Moltmann (Paris – Pantheon Sorbonne) and Jason Turner (...) (Leeds). The workshop’s scope is fairly large, focusing on three different aspects of contemporary research in metaphysics. However, the underlying idea of organizers Thomas Sattig and Alessandro Torza consisted in exploring their interconnections and even new areas which possibly share the same problem spectrum. Also, they thought of bringing together both young and senior protagonists of the contemporary debate. In this sense, the main thread followed by the speakers consisted in enquiring the ideas of fundamentality, dependence and grounding with respect to ontology (Berto, López de Sa, Turner) and the truthmaking debate (Priest, Moltmann, Leuenberger), thus pretty much in line with some latest tendencies in metaphysics, such as, prima inter paria, the works of Kit Fine. When we say that something is more fundamental than something else, we move into a non-conventional (for the standards of 20 th century philosophy) metodological framework, hardly focusing on the question about what there is, and rather tackling the issue of how fundamentally there is what there is, or how the existence of something is required as a ground for the existence of other things. Here is how Jonathan Schaffer explains the methodological transition in his influential “On What Grounds What” (2009): -/- Among the many assumptions Quine and Carnap share is that metaphysical questions are existence questions, such as whether numbers exist. They only disagree on the further issue of whether such questions are meaningful (at least as the metaphysician might pose them). But why think that metaphysical questions are existence question of this sort? Return to Aristotle’s Metaphysics. There are virtually no existence question posed. The whole discussion is about substances (fundamental units of being). At one point Aristotle pauses to ask if numbers exist, and his answer is a brief and dismissive yes. [. . . ] For Aristotle, the question about numbers is whether they are transcendent substances or grounded in concreta. The question is not whether numbers exist, but how. (Schaffer, 2009, p. 347) -/- The conference opened with Graham Priest’s intriguing and peculiar review of Buddhist cornerstone “The Fundamental Verses of the Middle Way” (Mūlamadhyakamakārikā) by Nāgārjuna (ca. 150-ca. 250 AD), seen as a unrecognized forerunner of multi-valued semantics and dialetheism. Priest shows that Nagarjuna’s thought indeed has valuable analytic grip (contrary to the traditional mystical dismiss of his works altogether) and is even in accord to some formal schemas rejecting both the laws of excluded middle and non-contradiction. Dan López de Sa was interested in the topic of grounding, raising concerns about how to explain the kind of “reality” exemplified by what is not fundamental, but rather derivative on something else. He proposes a conceptual and non-primitive analysis of grounding as linked to fundamentality and derivation, and argues that the view can be advocated along with the acceptance that at least something is not fundamental. Subsequently, he illustrates an impressive range of applications linked to contemporary debates in meta-ontology, truthmaking and philosophy of time. Stephan Leuenberger discussed a semantics for “total logic”, a variant of first order logic which is claimed to have several applications with respect to the issue of excluding negative existentials from the scope of theories accounting for a given ’totality’ of facts. For example, materialism is the claim that everything there is can be traced back to physical facts or to truth implied by those facts. What about the claim that “There are no angels”? According to Leuenberger, ordinary logic falls prey of modal arguments (if it is possible that there are angels, by modus tollens, that it is not metaphysically necessary that everything there is is physical). So, there is space for the introduction of a new operator, the totality operator, claiming of what enters its scope that “that’s the whole truth”. Consequently, total logic’s semantics tackles David Chalmers’ well-known conceivability-based argument in favour of zombie’s (subjects producing behaviour but experiencing no qualia) possible existence. Friederike Moltmann presented a massive array of natural language-based examples on the role played by case-constructions, such as “it is the case that Caesar crossed the Rubicon”, “the case of the stolen statue”, “the case in which it might rain”, and so forth. She suggests that we should take surface phenomena of our language very seriously with regard to the determination of ontological categories and truth-makers. Cases are provided by many natural languages with their own existence predicates (“to occur” and “to present itself ”), and these do not apply to other kind of entities, such as objects and events. Trying to derive a substantive thesis on their nature, she claims that they are filtered entities, a structure taking into account some features of the corresponding objects and events and preserving their relational pattern. Jason Turner discussed meta-ontological concerns against the claim that ontological debates are defective. Analysed the structure of a metaphysical theory and identified two different forms of defectiveness that can occur in ontological questions, the defection from without and the defection from within, the author provided an original solution in order to avoid such difficulties. He argued thus in favor of a logical constancy, a translation principle thanks to it would be possible reconceive an ontological defection. Lastly, Francesco Berto’s talk closed the workshop with a sagacious discussion of meinongian quantification. He substains that Meinongians and Quineans experience no conceptual equivocation. Even if the former claims that “There are things that do not exist”, something that the latter contrasts with the interpretation of existential quantifiers as all-including, they still rely upon the same concept of “existence” and they understand each other when they are outside the ontology room, so that it cannot be that they lack competence. Subsequently, Berto deals with the objection that Meinongians commit analytic falsehood in separating the meaning of “to be” from that of “exists”. The Quinean has no independent evidence for analytic equivalence aside from her emphatic stress on the “is” in “there is”. Meinongians, however, can retort to linguistic considerations and claim that existence predicates display fairly different functions. -/- As for what regards our internal division of the “philosophical labor”, Fabio Ceravolo reviewed Moltmann and Berto’s talks; whereas Mattia Cozzi took care of Priest’s and Leuenberger’s, and Mattia Sorgon of those given by López de Sa and Turner. Conclusively, we would like to thank Thomas Sattig and Alessandro Torza for all of their organizational efforts and the kind welcome they reserved to us. We hope we will have further opportunities to collaborate with Tübingen in supporting similarly innovative and valiant european initiatives. (shrink)

If one does not possess an immaterial and immortal soul, then the prospect of conscious experience after death would appear to depend upon the metaphysical possibility of the resurrection of one’s biological life.[i] By “resurrection,” I don’t mean just the possibility that a dead but still existing and well preserved individual could be brought back to life. My contention is that the human organism can even cease to exist, perhaps as a result of cremation or extensive decay, and yet (...) still can be brought back into existence at a later time. That is, the same organism can live again after a period of nonexistence. However, a number of philosophers, religious and secular, insist that once an individual ceases to exist he does so forever, regardless of whether God or a future technology reassembles his atoms. Their claim is that the resulting human being would be a duplicate, for intermittent existence is impossible - at least for living creatures. In the pages that follow, I aim to establish, not that the dead will be resurrected, but that some of the alleged barriers to such an event are dubious. My contention is that resurrection after a period of nonexistence is not a metaphysically impossible state of affairs. (shrink)

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)

Recently, Terry Horgan and Matjaž Potrč have defended the thesis of ‘existence monism’, according to which the whole cosmos is the only concrete object. Their arguments appeal largely to considerations concerning vagueness. Crucially, they claim that ontological vagueness is impossible, and one key assumption in their defence of this claim is that vagueness always involves ‘sorites-susceptibility’. I aim to challenge both the claim and this assumption. As a consequence, I seek to undermine their defence of existence monism and (...) support a common-sense pluralist ontology of ‘ordinary objects’ as being fully consistent with a thoroughgoing metaphysical realism.

Avicenna's proof for the existence of God (the Necessary Existent) in the Metaphysics of the Salvation relies on the claim that every possible existent shares a common cause. I argue that Avicenna has good reason to hold this claim given that he thinks that (1) every essentially ordered causal series originates in a first, common cause and that (2) every possible existent belongs to an essentially ordered series. Showing Avicenna's commitment to 1 and 2 allows me to respond to (...) Herbert Davidson's and Richard Swinburne's claim that Avicenna's proof for the Necessary Existent is incomplete and fallacious -/- . (shrink)

This paper examines our pre-theoretic conception of non-supernaturalism; the thesis that all that exists is natural. It is argued that we intuitively take this thesis to be a substantive, non-dogmatic, empirically justified, not merely contingent truth. However, devicing an interpretation of non-supernaturalism that captures all aspects of this intuition is difficult. Indeed, it is found that this intuition conflates the strong inferential scope of a metaphysical claim with the modest justificatory requirements of an empirical matter of fact. As such, (...) non-supernaturalism, in itspre-theoreticform, contains an internal tension that must be navigated whenever the thesis features in systematic thinking. (shrink)

Being dedicated to the memory of the great Catholic philosopher Elizabeth Anscombe, who died in the month it was given, this Aquinas lecture begins with some reflections on the relationship between the anti-scientistic, anti-Cartesian position argued for by Anscombe and her teacher Wittgenstein, and the outlook of Thomas Aquinas. It then proceeds to explore the familiar Thomistic idea that philosophical reflection provides the means to establish the existence of God. Drawing in part on Aquinas, but also and perhaps unexpectedly (...) on the idealism of Berkeley and on the semantic intuitionism of Michael Dummett (a former student of Anscombe), I argue that theism follows both from the assumption of realism and from the assumption of anti-realism, and that this fact reveals something of the complexity involved in the claim that God both creates and knows the world. Finally, I examine the relationship between Aristotelian-Thomistic pluralistic realism and the attempt by John McDowell to fashion a position that lies between Platonism and reductive naturalism.

This book addresses central issues in the philosophy and metaphysics of science, namely the nature of scientific theories, their partial truth, and the necessity of scientific laws within a moderate realist and empiricist perspective. Accordingly, good arguments in favour of the existence of unobservable entities postulated by our best theories, such as electrons, must be inductively grounded on perceptual experience and not their explanatory power as most defenders of scientific realism claim. Similarly, belief in the reality of dispositions such (...) as causal powers which ground the natural necessity of scientific laws must be based on experience. Hence, this book offers a synthetic presentation of an original metaphysics of science, namely a metaphysics of properties, both categorical and dispositional, while at the same time opposing strong versions of necessitarism according to which laws are true in all possible worlds. The main theses and arguments are clearly presented in a non-technical way. Thus, on top of being of interest to the specialists of the topics discussed, it is also useful as a textbook in courses for third year and more advanced university students. (shrink)

This work in metaphysics adheres to the critical demands of Immanuel Kant for what Kant would call a science of metaphysics, in that it consits strictly of a priori principles that, while from pure reason, can help make sense of our phenomenal world (Kant's criterion for objective validity). The work has an Appendix quoting Kant's most relevant remarks with regard to a science, and offers parallel quotes from David Hume's "Treatise of Human Nature". The work advances the explanation of a (...) causal process that accounts for the origination of the universals: space, time, mass (or substance), and mind (or consciousness), and it necessitates the existence of God as Absolute Being and Absolute Mind. Hegel's 'Science of Logic' is quoted wherein Hegel makes an analogous claim. The causal process is defined with both a definite beginning and a definite end and agreement can be found with the statement found in the book of Revelation, final chapter: "I am the Alpha and the Omega, the first and the last, the beginning and the end." The statement suggests a movement that is not in conflict with the science, and seems to reflect Hegel's own thoughts. The science does not conflict with, but it further finds agreement with the science of big bang cosmology, but it goes further in necessitating a 'singularity' at the beginning of time. The causal process defined has a Formative Phase and a Creative Phase, with the former preceding the big bang and the latter following after the big bang. (shrink)

In this paper I argue, that if it is metaphysically possible for it to have been the case that nothing existed, then it follows that the right modal logic cannot extend D, ruling out popular modal logics S4 and S5. I provisionally defend the claim that it is possible for nothing to have existed. I then consider the various ways of resisting the conclusion that the right modal logic is weaker than D.

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)

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)

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.

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.

Suppose that A explains B. Do A and B need to be true? Provided that we have metaphysical explanation in mind, orthodoxy answers “yes:” metaphysical explanation is factive. This article introduces and defends a non-factive notion of metaphysical explanation. I argue that we need a non-factive notion of explanation in order to make sense of explanationist arguments where we motivate a view by claiming that it offers better explanations than its competitors. After presenting and rejecting some initially (...) plausible rivals, I account for non-factive metaphysical explanation by drawing on existing applications of structural equation models to metaphysical grounding.

Many contemporary metaphysicians believe that the existence of a contingent object such as Socrates metaphysically explains the existence of the corresponding set {Socrates}. This paper argues that this belief is mistaken. The argument proposed takes the form of a dilemma. The expression “{Socrates}” is a shorthand either for the expression “the set that contains all and only those objects that are identical to Socrates” or for the expression “the set that contains Socrates and nothing else”. However, Socrates' (...) class='Hi'>existence does not explain the existence of the set that contains all and only those objects that are identical to Socrates, because there is such a set no matter whether or not Socrates exists. And although Socrates' existence does explain that of the set that contains Socrates and nothing else, this explanation is a conceptual rather than a metaphysical one. Both these claims rely on a deflationary account of the use of set theoretic vocabulary that is explained, though not properly justified, in the paper. (shrink)

The view that quantum particles cannot be regarded as individuals was articulated in the early days of the 'quantum revolution' and became so well-entrenched that French and Krause called it 'the Received View'. However it was subsequently shown that quantum statistics is in fact compatible with a metaphysics of particle individuality, subject to certain caveats. As a consequent it has been claim that there exists a kind of underdetermination of the metaphysics by the physics which in turn has been used (...) to motivate a form of 'notice' structural realism. In this essay I will review this purported underdetermination and the motivation for structural realism that it purportedly provides in the context of recent developments in both the philosophy of physics and metaphysics. I aim to conclude that such developments reinforce the underdetermination and allow one to respond to certain critical concerns regarding its motivational power. (shrink)

The present paper argues that substantialist metaphysics are in tension with the physicalist idea that the universe is causally closed. The argument is a rather specific one and proceeds through three steps. The first step consists in arguing that monistic substance metaphysics allow for the existence of entities that cannot belong to the intended first order domain. This result sensitively depends on the nature of substances as invariant entities. The second step concludes that, if further domains are to be (...) admitted, then they are inhabited by “higher” or (systematically) “non-standard” entities and that, in both cases if not made somehow innocuous, such entities may take part on the metaphysical construction of the world through their own distinctive properties and causal powers. However, this latter claim is in contradiction with causal closure. But closure is the principle that mainly characterizes physicalist approaches in metaphysics and as such physicalist metaphysics cannot get rid of it. Who attempted making exotic properties and causal powers innocuous usually appealed to the Supervenience Argument. Unfortunately, as the third step proves, this argument is invalid. Finally, the paper looks forward and toward alternative models for physicalist metaphysics, like process-based models. (shrink)

The article is devoted to the well-known dispute between R. Carnap and W.V.O. Quine on the meaning of statements with names of abstractions, which also revealed their disagreements on the more general question of the nature of the dependence of ontology on the choice of language of knowledge. According to Quine, the choice of language carries with it certain ontological commitments – judgments of existence that must be true for anyone who appropriately uses the language in question. The language (...) of abstractions (using appropriate names and indications) is widely used not only in philosophy and everyday communication, but also in the sciences, including natural sciences. The names of abstractions (or, alternatively, quantification by corresponding entities) cannot be completely excluded from science, as Carnap, in particular, points out. He also considers it wrong to attribute to a scientist with empiricist views the belief in the existence of something that he, as an empiricist, is not ready to consider existing. In his view, the choice of language (framework) does not carry any ontological obligations: it determines what should be the correct answer to the so-called internal questions of the theory but does not affect metaphysical questions. Carnap interprets meaningful statements about abstractions as analytical truths, while Quine believes that most references to abstractions are removable from the language of science, and those that are not removable create additional ontological obligations, which, however, for some reason say nothing about reality itself. But why this is so, if the theory implicating them claims to describe reality, is not clear. This debate about the role of judgments about abstractions in scientific knowledge gave rise to a whole branch of metaphysical and ontological research, best known as metaontology. The main parties in this dispute are realists, who interpret irreducible abstractions as part of reality and denotations of certain names, and anti-realists, who, as a rule, deny the connection of statements with such names with reality, treating them as pseudo-statements or something similar. The solution to the problem, which is proposed in this article, consists in abandoning the belief, widespread both in philosophy and in everyday thought, which can be generally called “The theory of reference” and which consists in the fact that the contribution of names and certain other types of expressions to communication is their denotations. If we assume that names have no denotations at all and their semantic contribution to statements is only their senses or something similar, then the names of abstractions in this respect will be no different from other types of names. In this case, it would be no need to either assume that they designate some “Platonic” entities in order for some statements with them being true, nor interpret these judgments as pseudo-statements or as truths of some special kind that are not related to reality. The interpretation of statements with such names and their evaluation will not pose any special problem for the empiricist with this approach. (shrink)

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)

The view that human beings begin to exist at fertilization (namely conceptionism) faces a serious challenge from the twinning argument, that identical twins coming from the same zygote must be numerically distinct from the zygote and so did not exist at fertilization. Recently, some philosophers have claimed that the twinning argument rests on a particular metaphysical theory of persistence, namely endurantism, on which a human being, for example, is wholly present at every moment of her existence. And we (...) can easily refute the argument, they claim, by employing perdurantism or exdurantism, according to which a human being is a temporally extended entity with temporal parts or a momentarily existing stage who has other momentarily existing stages as counterparts. I argue that such claims are mistaken. The twinning argument does not rest on endurantism and can be formulated in terms of perdurantism to provide a good reason for perdurantists to reject conceptionism. And exdurantism does not have any advantage in defending conceptionism either, for it already concedes more than what the twinning argument aims to show. (shrink)

Many think that sentences about what metaphysically explains what are true iff there exist grounding relations. This suggests that sceptics about grounding should be error theorists about metaphysical explanation. We think there is a better option: a theory of metaphysical explanation which offers truth conditions for claims about what metaphysically explains what that are not couched in terms of grounding relations, but are instead couched in terms of, inter alia, psychological facts. We do not argue that our (...) account is superior to grounding-based accounts. Rather, we offer it to those already ill-disposed towards grounding. (shrink)

In lieu of an abstract, here is a brief excerpt of the content:Reviewed by:Mullā Ṣadrā and Metaphysics: Modulation of BeingLatimah-Parvin Peerwani ArlingtonMullā Ṣadrā and Metaphysics: Modulation of Being. By Sajjad H. Rizvi. Culture and Civilization in the Middle East Series, edited by Ian Richard Netton. London and New York: Routledge, 2009. Pp. xii + 222. Hardcover $135.00.In Mullā Ṣadrā and Metaphysics: Modulation of Being, Sajjad H. Rizvi focuses on tashkīk (modulation), variously translated as the systematic ambiguity, analogical gradation, or just (...) gradation of being from the perspective of Mullā Ṣadrā, comparing it with classical Islamic philosophy and contemporary Western philosophy. He states that he makes two major claims in this study. First, he argues that modulation is a hermeneutic concept that describes the threefold division of being and its gradation. Second, gradation and modulation occur in each mode of being. Each mode of being refers to a branch of Ṣadrā's philosophy: mental being is a discussion of epistemology and psychology; 'being-in-language' is critical to Sadrian semantic theory; being in re focuses on 'traditional metaphysics.' But the philosophy of Ṣadrā is not compartmentalized; being cuts across these fields and unites them. Each mode of being as modulated shares features of intensification. According to Rizvi, Ṣadrā has extended the normal understanding of modulation and of being beyond the simple division of the two realms of mental and concrete existence to bring out the semantics of being. This aspect of Islamic philosophy, according to Rizvi, has often been neglected (p. 3). [End Page 278]This study consists of an Introduction and two parts. In the Introduction, Rizvi states the problem of tashkīk as the central hermeneutic of Ṣadrian ontology. An analysis of this critical concept, according to Rizvi, facilitates our understanding of Ṣadrā's position on a wide variety of important philosophical issues such as predication, the problem of reconciling unity and plurality in being, and God-world relationship. It provides an answer to the age-old problem of the One and the many, and the median way between the ontological monism of Ibn ʿArabi and the metaphysical pluralism of Avicenna. Rizvi says that according to Ṣadrā there are four levels of being: the concept of being, its reality, its uttered manifestation (sound), and its written manifestation.Part 1 consists of two chapters. In the first chapter Rizvi outlines his methodology and some of his assumptions about the cultural history of the period and the context of Ṣadrā. The significant contention, according to Rizvi, is that a proper understanding of Ṣadrā's philosophy requires an appreciation of philosophy in the Neoplatonic traditions "as a way of life" that is often closely related to spiritual practice and religious commitment. The aim of philosophical inquiry for Ṣadrā, according to Rizvi, is therapy for the rational soul and its perfecting and development in its path of return to its origins in the One.Four methodological approaches are utilized in this study. (1) Tashkīk is seen as the central hermeneutic of Ṣadrian metaphilosophy, and not ontology; Rizvi argues that tashkīk is a central guiding principle in Ṣadrā's metaphilosophy and permeates all branches of his philosophical system. (2) The aporetic method is used in analyzing Ṣadrā's philosophy. (3) Rizvi maintains that Ṣadrā's philosophy is processual, for it represents a shift from substance to process metaphysics. (4) Ṣadrian hikmat (philosophy, wisdom) is approached as a metaphilosophical inquiry. Metaphysics is a foundational science for Ṣadrā, instrumental in the possibility of acquiring knowledge and in the construction of definitions and meaningful discourse. Hikmat, according to Rizvi, is doubly transcendent, (1) as a higher synthesis of Avicennan, Illuminationist, Sufi, and esoteric Shiʿite systematic thought, and (2) as a prophetic philosophy that claims to be derived from direct 'revelation.'The second chapter introduces the tashkīk (modulation) of being. Rizvi traces its historical development from the Aristotelian pros hen homonym to Avicenna, Nasir al-Din Tusi, and Ibn ʿArabi, and offers an account of an intensifying scale of being toward a hierarchy of being that is singular but with multiple degrees defined by their intensity, that is, in terms of scales of intensification and deliberation. He makes explicit the Neoplatonic logic of being that this implies and examines how... (shrink)

In this essay I comparatively evaluate two realist metaphysical accounts of modality: David Lewis’ (1986) genuine modal realism (GMR), and neo-Aristotelian modal realism (AMR) as put forth by Alexander Pruss (2011). GMR offers a reductive analysis of modal claims of possibility and necessity in terms of claims quantifying over concrete worlds and counterparts, and is in this way committed the existence of a plurality of concrete worlds other than the actual world; AMR, on the other hand, (...) offers an analysis of modal claims in terms of claims about the causal powers of existing objects in the actual world, and identifies these powers and powerful properties as the truthmakers for modal truths of possibility and necessity. I consider two objections to GMR; firstly, that it leads to ethical paradoxes, and secondly, that the counterparts it offers as truthmakers for modal claims are fundamentally irrelevant to the de re modal properties of objects. I argue that AMR bears a prima facie advantage over GMR by reason of its avoidance of those two objections, before evaluating two objections faced by AMR itself, namely, that its analysis is not genuinely explanatory, and secondly, that the ontology of powers fails to account for the full range of metaphysical possibility. I argue that AMR has the resources to avoid these objections, that AMR on balance is more attractive, and that therefore AMR is worthy of serious consideration by advocates of GMR.

The metaphysical status of the placenta has bearing on several ongoing discussions within Catholic moral theology. Numerous bioethicists and theologians have touched on this topic briefly, but to date no robust metaphysical argument appears in the literature. The authors aim to provide such an analysis. First, they provide an overview of the existing literature on the topic. Second, they briefly review the anatomy and physiology of the placenta. Third, they provide metaphysical and biological reasons why the placenta (...) cannot be a part of the fetus, a part of the mother, simultaneously a part of both, the border at which mother and fetus meet, or a separate individual substance. Finally, they provide reasons that support their claim that the placenta is a quasi-substance that exists in symbiosis with mother and child. National Catholic Bioethics Quarterly 14.2 : 295–333.

If I see, hear, or touch a sparrow, the sparrow seems real to me. Unlike Bigfoot or Santa Claus, it seems to exist; I will therefore judge that it does indeed exist. The “sense of existence” refers to the kind of awareness that typically grounds such ordinary judgments of existence or “reality.” The sense of existence has been invoked by Humeans, Kantians, Ideologists, and the phenomenological tradition to make substantial philosophical claims. However, it is extremely controversial; (...) its very existence has been called into question. This paper aims to clarify the nature and reality of the sense of existence by studying a psychiatric condition in which the sense appears to be disrupted: depersonalization disorder (DPD). (shrink)

A formal theory of quantity T Q is presented which is realist, Platonist, and syntactically second-order (while logically elementary), in contrast with the existing formal theories of quantity developed within the theory of measurement, which are empiricist, nominalist, and syntactically first-order (while logically non-elementary). T Q is shown to be formally and empirically adequate as a theory of quantity, and is argued to be scientifically superior to the existing first-order theories of quantity in that it does not depend upon empirically (...) unsupported assumptions concerning existence of physical objects (e.g. that any two actual objects have an actual sum). The theory T Q supports and illustrates a form of naturalistic Platonism, for which claims concerning the existence and properties of universals form part of natural science, and the distinction between accidental generalizations and laws of nature has a basis in the second-order structure of the world.

Classic inductive skepticism–the epistemological claim that we have no good reason to believe that the unobserved resembles the observed–is plausibly everyone’s lot, whether or not they embrace Hume’s metaphysical claim that distinct existents are “entirely loose and separate”. But contemporary advocates of a Humean metaphysic accept a metaphysical claim stronger than Hume’s own. I argue that their view plausibly gives rise to a radical inductive skepticism–according to which we are downright irrational in believing as we do about the (...) unobserved–that we don’t otherwise have reason to accept. The Metaphysical Neo-Humean is in an epistemological quagmire all her own. (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.

Suppose nothing exists. Then it is true that nothing exists. What makes that true? Nothing! So it seems that if nothing existed, then the principle that every truth is made true by something (the truthmaker principle) would be false. So if it is possible that nothing exists, a claim often called 'metaphysical nihilism', then the truthmaker principle is not necessary. This paper explores various ways to resolve this conflict without restricting metaphysical nihilism in such a way that it (...) would become trivial and uninteresting. (shrink)

Metaphysics deals with the intelligible world of questions and the explicable world of intentionality. Metaphysics is explicable, and its explicability is connected to questions related to what there is to know about the nature of reality. While physics deals with what is and what else there is, metaphysics deals with the nature of reality and what else there is to know about the nature of reality. If the content of metaphysics is considered as "answers" to questions related to cosmology and (...) consciousness, then metaphysical claims must be understood in the context of the questions that necessitate such claims. For without understanding the relevance of the questions, we cannot establish the 'truth' or 'falsity' of metaphysical claims. The relevance of the questions is the basis for establishing the veracity of the metaphysical distinctions. Hence, all metaphysical distinctions are a non-reductive explanation of what is considered as being reductive. The content of consciousness or intentionality deals with the following metaphysical distinctions, namely, the matter/mind, the essence/ existence, the space/time, the concrete/abstract, the particular/universal, and the contingent/necessary distinctions. These distinctions are made possible because of the questions raised by the intelligent mind. Two questions that connect physics and metaphysics are-- what is there and the nature of what is there. Two further questions that promote our interest in physics and metaphysics are: what else is there to know, and what else is there to know about the nature of reality. Reality and the nature of reality are the same. However, because the mind makes this distinction, we can state that what is physical is an empirical given, and what is metaphysical is a phenomenological or an existential given. Keywords: metaphysics, intentionality, subjectivity, creativity, freedom and time. (shrink)

These original essays offer evidence that a growing number of Anglo-American philosophers are finding in the classical discussion of God's existence and nature fertile sources for critical reflection on issues in the philosophy of religion. Nelson Pike challenges Aquinas' claim that God is not responsible for evil and shows how the rejection of this claim bears on the problem of evil. Richard Swinburne defends the classical Christian understanding of heaven and hell, arguing that it is both philosophically plausible and (...) compatible with the Christian conception of God's goodness. Philip Quinn proposes a defensible version of the classical assertion that God's conserving a creature in existence is tantamount to his continuously creating that creature. Thomas Flint and Alfred Freddoso present an analysis of omnipotence which they claim to be both philosophically adequate and consonant with the orthodox Christian belief that God is both omnipotent and incapable of sinning. James Ross's main purpose is to dislodge the assumption that God's power is properly and adequately thought of as the power to cause (or bring about or actualize) states of affairs. Clement Dore reinterprets and defends Descartes' often maligned Fifth Meditation argument for God's existence. Finally, Mark Jordan explicates the metaphysical foundations of Aquinas' doctrine of divine names. (shrink)

The paper argues that metaphysics depends upon science when it comes to claims about the constitution of the real world. That thesis is illustrated by considering the examples of global supervenience, the tenseless vs. the tensed theory of time and existence, events vs. substances, and relations vs. intrinsic properties. An argument is sketched out for a metaphysics of a four-dimensional block universe whose content are events and their sequences, events consisting in physical properties instantiated at space-time points, these (...) properties being relations rather than intrinsic properties.

The aim of this paper is to clarify Spinoza’s views on some of the most fundamental issues of his metaphysics: the nature of God’s attributes, the nature of existence and eternity, and the relation between essence and existence in God. While there is an extensive literature on each of these topics, it seems that the following question was hardly raised so far: What is, for Spinoza, the relation between God’s existence and the divine attributes? Given Spinoza’s (...) class='Hi'>claims that there are intimate connections between God’s essence and his existence – “God’s essence and his existence are one and the same”(E1p20) – and between God’s essence and the attributes – “By attribute I understand what the intellect perceives of substance, as constituting its essence” (E1d4), we would naturally expect that by transitivity, there is a significant relation between God’s existence and the attributes. Yet, as far as I know, there is little, if any, attempt in the existing literature to explicate such a relation, and it is one of my aims of this study to both raise the question and answer it. Eventually, I will argue that for Spinoza God is nothing but existence, and that the divine attributes are just fundamental kinds of existence, or, what is the same, as I will later argue, the intellect’s most fundamental and adequate conceptions of existence. In the first part of the paper I provide some background for Spinoza’s brief discussion in the TTP of God’s name and essence by studying the claims of Maimonides in the Guide of the Perplexed that God’s true essence is necessary existence, and that this essence is denoted by the ineffable Hebrew name of God, the Tetragrammaton (YHVH). In the second part of the paper I point out similar claims Spinoza presents in the TTP, and show how they respond to and echo Maimonides’ discussion in the Guide. In the third part, I examine Spinoza’s apparently conflicting claims in the Ethics about the relationship between God’s essence and existence. In some places Spinoza claims that God’s essence and existence are strictly identical (E1p10: “God’s essence his existence are one and the same”), but in other passages he makes the apparently much more modest claim that God’s essence involves existence (E1d1, E1p7d and E1p11d), which may lead one to believe that there is more to God’s essence than mere existence. I show that Spinoza’s understanding of the relation denoted by the Latin ‘involvit’ is consistent with the strict identification of essence and existence in God, and that Spinoza identifies God’s essence with self-necessitated existence, or eternity. Indeed, Spinoza’s understanding of eternity [aeternitas] as self-necessitated existence (E1d8) is one of the very few Spinozistic concepts that has no trace in Descartes. In this part I will also solve the long-standing problem of the sense in which the infinite modes can be called ‘eternal.’ In the fourth part I turn to the relation between the divine attributes and God’s existence and argue that, for Spinoza, the attributes are self-sufficient and adequate conceptions of existence. Finally, I will attempt to explain what brought Spinoza to deify existence. -/- Part I: “In that Day shall God be One, and his Name One”- Maimonides on God’s Name and Essence. -/- 1.1 Before we delve into the texts, let me suggest a few distinctions between various views on the issue of the relation between essence and existence in God. The view I suspect both Maimonides and Spinoza subscribe to can be termed the divine essence-existence Identity Thesis. -/- Identity Thesis (IT): God’s essence is existence and nothing but existence. We should distinguish the Identity Thesis from the much more common view according to which God’s essence contains existence, or (which I take to be roughly the same) that existence is one of the properties or perfections which constitute God’s essence. The latter view allows for the possibility (though it does not demand) that there is more to God’s essence than bare existence (e.g., God’s essence may include omniscience, omnipotence, etc.). I will term this view the divine essence-existence Containment Thesis. (shrink)

This paper examines Hegel’s claim that philosophy “has no other object than God‘ as a claim about the essentiality of the idea of God to philosophy. On this idealist interpretation, even atheistic philosophies would presuppose rationally evaluable ideas of God, despite denials of the existence of anything corresponding to those ideas. This interpretation is then applied to Hegel’s version of idealism in relation to those of two predecessors, Leibniz and Kant. Hegel criticizes the idea of the Christian God present (...) within his predecessors in terms of his own heterodox reading of the Trinity in order to resolve a paradox affecting them -- the “paradox of perspectivism‘.

In the history of Chinese and European philosophy, metaphysics has played an outstanding role: it is a theoretical framework which provides the basis for a philosophical understanding of the world and the self. A theory of the self is well integrated in a metaphysical understanding of the totality of nature as a dynamic process of continuous changes. According to this view, the purpose of existence can be conceived of as the development and realization of the full potential given (...) to the individual by its nature. In regard to human nature specifically, this idea of self-realization includes the development of all cognitive faculties as well as of the moral character. Metaphysics has, however, suffered a loss of importance in current debates, especially in ethics. As a result, we observe the emergence of such philosophical views as moral skepticism and even nihilism. The consequence of this tendency has been the renunciation of a claim to understanding and to providing a solid ground for ethics. Yet an intercultural dialogue can provide us with some hope as the consolidation of debates on crucial topics of our traditions might indeed serve as the basis for a more powerful philosophy in the future.

Quine is routinely perceived as saving metaphysics from Carnapian positivism. Where Carnap rejects metaphysical existence claims as meaningless, Quine is taken to restore their intelligibility by dismantling the former’s internal–external distinction. The problem with this picture, however, is that it does not sit well with the fact that Quine, on many occasions, has argued that metaphysical existence claims ought to be dismissed. Setting aside the hypothesis that Quine’s metaphysical position is incoherent, one has (...) to conclude that his views on metaphysics are subtler than is often presupposed; both the received view that Quine saved metaphysics and the opposite view that Carnap and Quine are on the same anti-metaphysical team seem too one-sided if we take seriously Quine’s own pronouncements on the issue. In this paper, I offer a detailed reconstruction of Quine’s perspective on metaphysical existence claims. Scrutinizing his published work as well as unpublished papers, letters, and notebooks, I show how Quine is able to both blur the boundary between scientific sense and metaphysical nonsense and to argue that we cannot ask what reality is really like in a distinctively philosophical way. I argue that although Quine’s position is much closer to Carnap’s than the received view suggests, it still differs in two crucial respects. (shrink)

In a lot of domains in metaphysics the tacit assumption has been that whichever metaphysical principles turn out to be true, these will be necessarily true. Let us call necessitarianism about some domain the thesis that the right metaphysics of that domain is necessary. Necessitarianism has flourished. In the philosophy of maths we find it held that if mathematical objects exist, then they do of necessity. Mathematical Platonists affirm the necessary existence of mathematical objects (see for instance Hale (...) and Wright 1992 and 1994; Wright 1983 and 1988; Schiffer 1996; Resnik 1997; Shapiro 1997 and Zalta 1988) while mathematical nominalists, usually in the form of fictionalists, hold that necessarily such objects fail to exist (see for instance Balaguer 1996 and 1998; Rosen 2001 and Yablo 2005). In metaphysics more generally, until recently it was more or less assumed that whatever the right account of composition—the account of under what conditions some xs compose a y—that account will be necessarily true (for a discussion of theories of composition see Simons 1987 and van Inwagen 1987 and 1990; the modal status of the composition relation is explicitly addressed in Schaffer 2007; Parsons 2006 and Cameron 2007). Similarly, it has generally been assumed that whatever the right account is of the nature of properties, whether they be universals, tropes, or whether nominalism is true, that account will be necessarily true (though see Rosen 2006 for a recent suggestion to the contrary). In considering theories of persistence it has been widely held that whether objects endure or perdure through time is a matter of necessity (Sider 2001; though see Lewis 1999 p227 who defends contingent perdurantism). And with respect to theories of time it is frequently held that whichever of the A- or B-theory is true is necessarily true. A-theorists often argue that there is time in a world only if the A-theory is true at that world (see for instance McTaggart 1903; Markosian 2004; Bigelow 1996; Craig 2001) while B-theorists often argue that the A-theory is internally inconsistent (Smart 1987; Mellor 1998; Savitt 2000 and Le Poidevin 1991). Once again, we find a few recent contingentist dissenters. Bourne (2006) suggests that it is a contingent feature of time that it is tensed, and thus that the A-theory is contingently true. Worlds in which there exist only B-theoretic properties are worlds with time, it is just that time in those worlds time is radically different to the way it is actually. Other defenders of the B-theory, though not expressly contingentists, do offer arguments against versions of the A-theory that try to show that such A-theories theories are inconsistent with the actual laws of nature (see for instance Saunders 2002 and Callender 2000); these arguments, at least, leave room for the possibility that the A-theories in question are contingently false (at least on the assumption that the laws of nature are themselves contingent, an assumption that not everyone accepts). Despite some notable exceptions, necessitarianism has flourished in many, if not most, domains in metaphysics. One such exception is Lewis’ famous defence of Humean supervenience as a contingent claim about our world. Lewis does not argue that necessarily, the supervenience base for all matters of fact in a world is nothing but a vast mosaic of local matters of particular fact. Rather, he thinks that we have reason to think that our world is one in which Humean supervenience holds (see Lewis 1986 p9-10 and 1994). Another exception to the necessitarian orthodoxy is to be found in the lively debate about the modal status of the laws of nature. Here, if anything, contingentism has been the dominating force, with it generally being held that there are possible worlds in which different laws of nature hold (this view is defended by, among others, Lewis 1986 and 2010; Schaffer 2005 and Sidelle 2002). Necessitarian dissenters hold that the laws of nature are necessary, frequently because they think it is necessary that fundamental properties have the causal or nomic profiles they do (see for instance Shoemaker 1980 and 1988; Swoyer 1982; Bird 1995; Ellis and Lierse 1994). Nevertheless, when it comes to thinking about the nature of the laws themselves, the necessitarian presumption is back on firm footing. Though there is disagreement about whether the laws are generalisations that feature in the most virtuous true axiomatisation of all the particular matters of fact (often known as the Humean view of laws and defended by Ramsey 1978; Lewis 1986 and Beebee 2000) or whether laws are relations of necessity that hold between universals (a view defended by Armstrong 1983; Dretske 1977; Tooley 1977 and Carroll 1990) no one has seriously suggested that it might be a contingent matter which of these is the right account of laws. The necessitarian orthodoxy is not surprising since metaphysics is largely an a priori process. While a priori reasoning may be used to determine whether a proposition is necessary or contingent, it is not well placed (in the absence of a posteriori evidence) to determine whether a contingent proposition is actually true or false. Since metaphysicians aim to tell us which principles are true in which worlds, on the face of it the discovery that metaphysical principles are contingent seems to make part of the task of metaphysics epistemically intractable. In what follows I consider two reasons one might end up embracing contingentism and whether this would lead one into epistemic difficulty. The following section considers a route to contingent metaphysical truths that proceeds via a combination of conceptual necessities and empirical discoveries. Section 3 considers whether there might be synthetic contingent metaphysical truths, and the final section raises the question of whether if there were such truths we would be well placed to come to know them.

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.

Theories about the dawn of "principality of existence" or "principality of quiddity" stand in the realm of "confusion of term and concept fallacy". It is true that asalat as a term appeared for the first time in Mirdamad's works such as Taqwim al-Iman to mention the problem of principality of existence, but we should notice that its meaning as a concept can be tracked in Suhrawadi's works. If by the term asalat we mean having real extension, as it (...) is used in Mulla Sadra's work, we can, without any doubt, claim that Suhrawardi is among the proponents of principality of quiddity. Proposing the distinction of existence and quiddity by al-Faraby and Avicenna, some philosophers regarded this distinction as a real one. But Suhrawardi, by presenting about nine arguments, claimed that existence remains as a mental predicate and does not have any real extension. He made use of his theory in the realm of the Necessary Being through Itself. Avicenna had claimed that the essence of God is His Existence but Suhrawardi denied this Avicennan Peripatetic principle. He said that existence has no real extension and so the essence of God cannot be existence. He claimed that here iniyyah means indivisible life. It seems that Mulla Sadra's arguments for demonstrating the principality of existence posed versus Suhrawardi's arguments for the mental nature of existence. (shrink)

Grounding theorists insist that grounding and explanation are intimately related. This claim could be understood as saying either that grounding ‘inherits’ its properties from explanation or it could be interpreted as saying that grounding plays an important—possibly an indispensable—role in metaphysical explanation. Or both. I argue that saying that grounding ‘inherits’ its properties from explanation can only be justified if grounding is explanatory by nature, but that this view is untenable. We ought therefore to be ‘separatists’ and view grounding (...) and explanation as distinct. As it turns out, though, once grounding has been in this sense distinguished from the explanation it backs, the view that the role grounding plays in explanation justifies its introduction ends up in serious trouble. I conclude that the role grounding plays in explanation does not justify attributing to grounding whatever nature we think it has, and it most likely does not give us any special reason to think grounding exists.

The paper attempts to explicate and justify the position I call `Agency Incompatibilism'- that is to say, the view that agency itself is incompatible with determinism. The most important part of this task is the characterisation of the conception of agency on which the position depends; for unless this is understood, the rationale for the position is likely to be missed. The paper accordingly proceeds by setting out the orthodox philosophical position concerning what it takes for agency to exist, before (...) going on to explain why and how that orthodoxy should be challenged. The relations between my own views and those of others writing on the issues of free will and moral responsibility, in three crucial and inter-connected areas are then explored. These are (1) the question how animals should figure in the philosophy of action; (2) the question what the lesson is of `Frankfurt-style' examples; and (3) the distinction between so-called `leeway' incompatibilism and `source' incompatibilism. The paper moves on to consider and respond to various objections to Agency Incompatibilism, including the claim that to embrace the conception of agency that makes incompatibilism plausible is to beg the question against the compatibilist, and also the worry that determinism is an empirical thesis which ought not to be straightforwardly falsifiable by such a priori reasoning as Agency Incompatibilism appears to involve. I also try to rebut the worry that Agency Incompatibilism is committed to the existence of an unintelligible and/or naturalistically impossible variety of irreducible agent causation. (shrink)

Metaphysicians frequently appeal to intuition. But when is that appeal useful? I consider that question by focusing on our existential intuitions. In particular, I want to go some way to answering the question of whether, and when, appeal to existential intuitions is useful, by consid-ering the issue in the light of an argument for unrestricted composition. This argument appeals to a difference in the extent to which restricted and unrestricted compositionalists appeal to existential intuitions, and concludes that at the very (...) least, restricted compositionalists are on shak-ier epistemic ground than unrestricted compositionalists. Having outlined this argument for unrestricted composition, I con-sider the nature of the unrestricted existential quantifier in the context of three different metaphysical scenarios about the way the world might be: scenarios that differ with respect to whether the metaphysics of a world completely or uniquely settles the division of that world into ob-jects. I argue that appeal to intuition is not only useful but necessary if we are to determine the intension of ‘exists’ and hence its extension at any given world. But this appeal is not simply an appeal to our brute ex-istential intuitions—our dispositions actually to quantify over a certain domain. Rather, it requires equilibration over a set of worlds in which we consider our ‘quantificational’ dispositions in each world, where, importantly, included in this set of worlds are worlds in which the meta-physics differently settles the division of those worlds into objects. Ul-timately, I argue, our dispositions yield various conditional claims about our concept <existence>. These are conditional claims of the most ab-stract kind: they tell us, for instance, that if there is some natural, unique division of our world into objects, then the unrestricted quantifier ranges over all and only the objects in that domain. But, I will argue, our untu-tored, world-bound dispositions are no guide at all to what actually ex-ists even on the supposition that metaphysics alone does not uniquely or completely settle a natural division of our world into objects. Hence they are no guide to the nature of composition. And to the extent that certain restricted compositionalist views depend on such intuitions, so much the worse for them. Or so I shall argue.

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)

Material from this paper appears in Chap. 7 of my book Reason and Being, but there is also stuff here that isn't in the book. In particular, it discusses the claims that, for Spinoza, conceiving implies explaining and that existence is identical to or reducible to conceivability. So, if you're interested in those issues, this paper might be worth a read.

In his groundbreaking work of 1969, Spinoza's Metaphysics: An Essay in Interpretation, Edwin Curley attacked the traditional understanding of the substance-mode relation in Spinoza, which makes modes inhere in the substance. Curley argued that such an interpretation generates insurmountable problems, as had been already claimed by Pierre Bayle in his famous entry on Spinoza. Instead of having the modes inhere in the substance Curley suggested that the modes’ dependence upon the substance should be interpreted in terms of (efficient) causation, i.e., (...) as committing Spinoza to nothing over and above the claim that the substance is the (efficient) cause of the modes. These bold and fascinating claims generated one of the most important scholarly controversies in Spinoza scholarship of the past thirty-five years. In this chapter I argue against Curley’s interpretation and attempt to reestablish the traditional understanding of Spinozistic modes as inhering in God and as predicated of God. I also criticize Curley’s philosophical motivation for suggesting this interpretation. I do believe, however, that Curley is right about the existence of an intimate connection between the substance-mode relation and causation in Spinoza. In the next chapter I will study the notion of ‘immanent cause’, which merges efficient causality and inherence. I will clarify the relation between immanent, efficient and material causation, and show where precisely Spinoza diverged from the traditional Aristotelian taxonomy of causes. In the second chapter I also discuss the German Idealists’ view of Spinoza as an ‘acosmist’. Under this interpretation Spinoza was a modern reviver of Eleatic monism, who allegedly asserts the mere existence of God, and denies the reality of the world of particular things. Spinozistic modes - according to this reading - are nothing but passing and unreal phenomena. Though this view of Spinoza as an ‘acosmist’ can be supported by some lines in Spinoza’s thought, I believe it should be rejected since it is not consistent with some of the most central doctrines of the Ethics. In the final part of the second chapter I discuss the relation between modes and the attributes under which they fall, and suggest a terminological distinction between a ‘mode of God’ (i.e., a mode under all attributes) and a ‘mode of an attribute’ (i.e., a mode under a specific attribute), a distinction which can help us avoid some common confusions in the treatment of the issue.

In this book, Richard Brian Davis explores various attempts to solve the Dependence Problem – the problem posed by the following question: How can necessary truths stand to God in a one-way relation of dependence when neither they nor God could have failed to exist? Critics charge that this problem is insoluble. Davis argues at length that the most powerful and promising contemporary solutions to this problem – those offered by Linda Zagzebski, Brian Leftow, Thomas V. Morris, and William Mann (...) – are all fatally flawed. In making his case, Davis treats the reader to helpful and interesting discussions of counterpossibles, broadly logical necessity, identity statements, as well as the divine attributes of sovereignty, aseity, and simplicity. He concludes with what is perhaps the most forceful and sustained defense of the claim that necessary truths can stand to God in an asymmetrical relation of causal dependence. (shrink)

The study of economics has been a going concern among philosophers for the better part of twenty years without very many people even noticing that economics has a metaphysics. Indeed, among economists the term ‘metaphysical’ is probably an epithet of opprobrium, employed to suggest that a claim is untestable or otherwise without cognitive significance. Philosophers of economics will admit to the existence of an epistemology of economics—the study of the nature, extent and justification of economic knowledge. But even (...) this is controversial among some economists. The notion that economics might have a metaphysics as well as an epistemology will be scoffed at by those economists doubtful about the enterprise of the philosophy of economics altogether. Nevertheless, philosophers of economics should have no trouble identifying a metaphysics in some of the theoretical commitments of economics. (shrink)

The present paper argues that substantialist metaphysics are in tension with the physicalist idea that the universe is causally closed. The argument is a rather specific one and proceeds through three steps. The first step consists in arguing that monistic substance metaphysics allow for the existence of entities that cannot belong to the intended first order domain. This result sensitively depends on the nature of substances as invariant entities. The second step concludes that, if further domains are to be (...) admitted, then they are inhabited by “higher” or (systematically) “nonstandard” entities and that, in both cases if not made somehow innocuous, such entities may take part on the metaphysical construction of the world through their own distinctive properties and causal powers. However, this latter claim is in contradiction with causal closure. But closure is the principle that mainly characterizes physicalist approaches in metaphysics and as such physicalist metaphysics cannot get rid of it. Who attempted making exotic properties and causal powers innocuous usually appealed to the Supervenience Argument. Unfortunately, as the third step proves, this argument is invalid. Finally, the paper looks forward and toward alternative models for physicalist metaphysics, like processbased models. Keywords: Metaphysics of Quantities, Abstraction Principles, Locationism.

In lieu of an abstract, here is a brief excerpt of the content:Reviewed by:Metaphysics as Mediating Dialogue by Oliva BlanchetteMatthew MinerdBLANCHETTE, Oliva. Metaphysics as Mediating Dialogue. Washington, D.C.: The Catholic University of America Press, 2023. xi + 133 pp. Cloth, $75.00In this text, the author presents a personal synthesis of metaphysics using a lexicon of scholastic and Blondelian-Hegelian thought. The first chapter, "From Questions of Being to the Question of Being as Being," presents a quasi-phenomenological account of the emergence of (...) the analogical conception of order of various degrees of perfection of being as such, concretized in various domains that are physical/natural and human/cultural. In this first chapter, an important theme that emerges and becomes a golden thread throughout the text is the claim that the primary analogate of being is, within our experience, the human person and the human mode of activity in culture and religion. [End Page 538]The second chapter, "Metaphysics as Mediating Dialogue of the Crossroads of Intersubjective, Intercultural, and Interreligious Communication," is perhaps the densest, covering a number of points handled in the remainder of the book. In this chapter, Blanchette is concerned with showing how intercommunication takes place within discourse concerning both the shared principles of intelligent agents and ultimately in view of an orientation toward what he later will call the vertical transcendence of culture in relation to God. Both of these tasks are of critical importance for constituting the necessary background for a philosophy of culture and a philosophy of religion that can mediate among the various actualities of human existence amid the objective and subjective aspects of art, science, and moral mutual recognition of intelligent agents in community.The third chapter, "The Necessity of Metaphysics in the Struggle for World Peace and Justice," opens with an arguably theological observation that the rational agent has two ends, one of which is not attainable in this life involving some kind of "more direct relation with God" in the hereafter, and the other pertaining to the struggle toward the establishment of a "historical communal peace." The framework for this terminology is a scholastically aware engagement with Blondelian (and partly Hegelian) thought. This chapter is concerned with articulating the way that rational agents engage in the historical task of establishing a kind of universal spirit of intersubjective recognition, at least as an asymptotic goal within history, even if contention ultimately prevents the formation of such a single, unified, intrahistorical community. Blanchette argues that this project is possible only within the dual transcendence of the human person, namely, as cultural and as religious, the latter being the condition for the former. Metaphysics has the role of articulating such transcendence.The fourth chapter, "Metaphysics as the Way from Phenomenology to Theology," engages with some of the questions related to the "theological turn" in Continental phenomenology. Phenomenological inquiry, Blanchette argues, must acknowledge that it investigates only one order of being in the universe, the human-intentional (or "historico-social"), and therefore stands in need of metaphysics to mediate its subject material with other kinds of being (as is true, similarly, of other disciplines). However, he also contends that phenomenology offers a very important preamble for a "first-person ontology" that is sensitive to the specific cultural and historical being of spiritual beings, but ultimately, Blanchette argues, it does so as "part of the way up from the bottom" and as opening up to metaphysical speculation, which itself prevents theology from degenerating into a kind of superstition.In chapters 5 through 7, Blanchette traces out the kind of mediation that occurs between metaphysics and theology.
