The violation of Bell inequalities seems to establish an important fact about the world: that it is non-local. However, this result relies on the assumption of the statistical independence of the measurement settings with respect to potential past events that might have determined them. Superdeterminism refers to the view that a local, and determinist, account of Bell inequalities violations is possible, by rejecting this assumption of statistical independence. We examine and clarify various problems with superdeterminism, looking in particular at its (...) consequences on the nature of scientific laws and scientific reasoning. We argue that the view requires a neo-Humean account of at least some laws, and creates a significant problem for the use of statistical independence in other parts of physics and science more generally.

Eternalism, the view that what we regard locally as being located in the past, the present and the future equally exists, is the best ontological account of temporal existence in line with special and general relativity. However, special and general relativity are not fundamental theories and several research programs aim at finding a more fundamental theory of quantum gravity weaving together all we know from relativistic physics and quantum physics. Interestingly, some of these approaches assert that time is not fundamental. (...) If time is not fundamental, what does it entail for eternalism and the standard debate over existence in time? First, I will argue that the non-fundamentality of time to be found in string theory entails standard eternalism. Second, I will argue that the non-fundamentality of time to be found in loop quantum gravity entails atemporal eternalism, namely a novel position in the spirit of standard eternalism. (shrink)

We develop a new version of the causal theory of spacetime. Whereas traditional versions of the theory seek to identify spatiotemporal relations with causal relations, the version we develop takes causal relations to be the grounds for spatiotemporal relations. Causation is thus distinct from, and more basic than, spacetime. We argue that this non-identity theory, suitably developed, avoids the challenges facing the traditional identity theory.

A ‘duality’ is a formal mapping between the spaces of solutions of two empirically equivalent theories. In recent times, dualities have been found to be pervasive in string theory and quantum field theory. Naïvely interpreted, duality-related theories appear to make very different ontological claims about the world—differing in e.g. space-time structure, fundamental ontology, and mereological structure. In light of this, duality-related theories raise questions familiar from discussions of underdetermination in the philosophy of science: in the presence of dual theories, what (...) is one to say about the ontology of the world? In this paper, we undertake a comprehensive and non-technical survey of the landscape of possible ontological interpretations of duality-related theories. We provide a significantly enriched and clarified taxonomy of options—several of which are novel to the literature. (shrink)

‘Space does not exist fundamentally: it emerges from a more fundamental non-spatial structure.’ This intriguing claim appears in various research programs in contemporary physics. Philosophers of physics tend to believe that this claim entails either that spacetime does not exist, or that it is derivatively real. In this article, I introduce and defend a third metaphysical interpretation of the claim: reductionism about space. I argue that, as a result, there is no need to subscribe to fundamentality, layers of reality and (...) emergence in order to analyse the constitution of space by non-spatial entities. It follows that space constitution, if borne out, does not provide empirical evidence in favour of a stratified, Aristotelian in spirit, metaphysics. The view will be described in relation to two particular research programs in contemporary physics: wave function realism and loop quantum gravity. (shrink)

Important features of space and time are taken to be missing in quantum gravity, allegedly requiring an explanation of the emergence of spacetime from non-spatio-temporal theories. In this paper, we argue that the explanatory gap between general relativity and non-spatio- temporal quantum gravity theories might significantly be reduced with two moves. First, we point out that spacetime is already partially missing in the context of general relativity when understood from a dynamical perspective. Second, we argue that most approaches to quantum (...) gravity already start with an in-built distinction between structures to which the asymmetry between space and time can be traced back. (shrink)

I will defend two claims. First, Schaffer's priority monism is in tension with many research programs in quantum gravity. Second, priority monism can be modified into a view more amenable to this physics. The first claim is grounded in the fact that promising approaches to quantum gravity such as loop quantum gravity or string theory deny the fundamental reality of spacetime. Since fundamental spacetime plays an important role in Schaffer's priority monism by being identified with the fundamental structure, namely the (...) cosmos, the disappearance of spacetime in these views might undermine classical priority monism. My second claim is that priority monism can avoid this issue with two moves: first, in dropping one of its core assumptions, namely that the fundamental structure is spatio-temporal, second, by identifying the connection between the non-spatio-temporal structure and the derivative spatio-temporal structure with mereological composition. (shrink)

Spacetime functionalism is the view that spacetime is a functional structure implemented by a more fundamental ontology. Lam and Wüthrich have recently argued that spacetime functionalism helps to solve the epistemological problem of empirical coherence in quantum gravity and suggested that it also (dis)solves the hard problem of spacetime, namely the problem of offering a picture consistent with the emergence of spacetime from a non-spatio-temporal structure. First, I will deny that spacetime functionalism solves the hard problem by showing that it (...) comes in various species, each entailing a different attitude towards, or answer to, the hard problem. Second, I will argue that the existence of an explanatory gap, which grounds the hard problem, has not been correctly taken into account in the literature. (shrink)

According to a number of approaches in theoretical physics, spacetime does not exist fundamentally. Rather, spacetime exists by depending on another, more fundamental, non-spatiotemporal structure. A prevalent opinion in the literature is that this dependence should not be analyzed in terms of composition. We should not say, that is, that spacetime depends on an ontology of non-spatiotemporal entities in virtue of having them as parts. But is that really right? On the contrary, we argue that a mereological approach to dependent (...) spacetime is not only viable, but promises to enhance our understanding of the physical situation. (shrink)

The question of whether Everettian quantum mechanics (EQM) justifies the existence of metaphysical indeterminacy has recently come to the fore. Metaphysical indeterminacy has been argued to emerge from three sources: coherent superpositions, the indefinite number of branches in the quantum multiverse and the nature of these branches. This paper reviews the evidence and concludes that those arguments don’t rely on EQM alone and rest on metaphysical auxiliary assumptions that transcend the physics of EQM. We show how EQM can be ontologically (...) interpreted without positing metaphysical indeterminacy by adopting a deflationary attitude towards branches. Two ways of developing the deflationary view are then proposed: one where branches are eliminated, and another where they are reduced to the universal quantum state. (shrink)

The relevance of analytic metaphysics has come under criticism: Ladyman & Ross, for instance, have suggested do discontinue the field. French & McKenzie have argued in defense of analytic metaphysics that it develops tools that could turn out to be useful for philosophy of physics. In this article, we show first that this heuristic defense of metaphysics can be extended to the scientific field of applied ontology, which uses constructs from analytic metaphysics. Second, we elaborate on a parallel by French (...) & McKenzie between mathematics and metaphysics to show that the whole field of analytic metaphysics, being useful not only for philosophy but also for science, should continue to exist as a largely autonomous field.

Surface presentism is the combination of a general relativistic physics with a presentist metaphysics. In this paper, we provide an argument against this combination based on black holes. The problem focuses on the notion of an event horizon. We argue that the present locations of event horizons are ontologically dependent on future black hole regions, and that this dependence is incompatible with presentism. We consider five responses to the problem available to the surface presentist, and argue that none succeed. Surface (...) presentism thus faces the prospect of refutation based on evidence that confirms the existence of black holes. (shrink)

A number of philosophers have argued in favour of extended simples on the grounds that they are needed by fundamental physics. The arguments typically appeal to theories of quantum gravity. To date, the argument in favour of extended simples has ignored the fact that the very existence of spacetime is put under pressure by quantum gravity. We thus consider the case for extended simples in the context of different views on the existence of spacetime. We show that the case for (...) extended simples based on physics is far more complex than has been previously thought. We present and then map this complexity, in order to present a much more textured picture of the argument for extended simples. (shrink)

Penrose's conformal cyclic cosmology describes the cosmos as a collection of successive universes, the so-called aeons. The beginning and ending of our universe are directly connected to two other, anterior and posterior, universes. Penrose considers but rules out a different interpretation of conformal cyclic cosmology: that the beginning of our universe is connected to its own end in a cosmic loop. The paper argues that the view, aeon monism, should be regarded as a natural interpretation of conformal cyclic cosmology and (...) discusses its implications for the concept of eternal return in light of the most popular metaphysics of time.

Several philosophers, both in Buddhist and Western philosophy, claim that the self does not exist. The no-self view may, at first glance, appear to be a reason to believe that life is meaningless. In the present article, I argue indirectly in favor of the no-self view by showing that it does not entail that life is meaningless. I then examine Buddhism and argue, further, that the no-self view may even be construed as partially grounding an account of the meaning of (...) life. (shrink)

Ted Sider argues that nihilism about objects is incompatible with the metaphysical possibility of gunk and takes this point to show that nihilism is flawed. I shall describe one kind of nihilism able to answer this objection. I believe that most of the things we usually encounter do not exist. That is, I take talk of macroscopic objects and macroscopic properties to refer to sets of fundamental properties, which are invoked as a matter of linguistic convention. This view is a (...) kind of nihilism : it rules out the existence of objects; that is, from an ontological point of view, there are no objects. But unlike the moderate nihilism of Mark Heller, Peter van Inwagen and Trenton Merricks that claims that most objects do not exist, I endorse a radical nihilism according to which there are no objects in the world, but only properties instantiated in spacetime. As I will show, radical nihilism is perfectly compatible with the metaphysical possibility of gunk. It is also compatible with the epistemic possibility that we actually live in a gunk world. The objection raised by Ted Sider only applies to moderate nihilism that admits some objects in its ontology. (shrink)

Metaphysics of Quantum Gravity The metaphysics of quantum gravity explores metaphysical issues related to research programs in theoretical physics clustered under the term quantum gravity. These research programs aim at the formulation of a theory that reconciles the theory of general relativity with quantum theory.

In a recent article, Ned Markosian gives an argument against four-dimensionalism understood as the view that time is one of four identical dimensions that constitute a single four-dimensional manifold. In this paper, I show that Markosian attacks a straw man as his argument targets a theory known to be false on empirical grounds. Four-dimensionalism rightly conceived in no way entails that time is identical to space. I then address two objections raised by Markosian against four-dimensionalism rightly conceived.

I will introduce and motivate eliminativist super-relationism. This is the conjunction of relationism about spacetime and eliminativism about material objects. According to the view, the universe is a big collection of spatio-temporal relations and natural properties, and no substance (material or spatio-temporal) exists in it. The view is original since eliminativism about material objects, when understood as including not only ordinary objects like tables or chairs but also physical particles, is generally taken to imply substantivalism about spacetime: if properties are (...) directly instantiated by spacetime without the mediation of material objects, then, surely, spacetime has to be a substance. After introducing briefly the two debates about spacetime (§1) and material objects (§2), I will present Schaffer's super-substantivalism (§3), the conjunction of substantivalism about spacetime and eliminativism about material objects at the fundamental level. I shall then expose and discuss the assumption from which the implication from eliminativism to substantivalism is drawn, and discuss the compatibility of eliminativism with relationism: if spacetime is not a substance, and if material objects are not real, how are we to understand the instantiation of properties (§4)? And what are the relata of spatio-temporal relations (§5)? I then show that each argument in favor of super-substantivalism offered by Schaffer also holds for super-relationism (§6) and examine several metaphysical consequences of the view (§7). I conclude that both super-substantivalism and super-relationism are compatible with Schaffer's priority monism (§8). (shrink)

The present volume collects essays on the philosophical foundations of quantum theories of gravity, such as loop quantum gravity and string theory. Central for philosophical concerns is quantum gravity's suggestion that space and time, or spacetime, may not exist fundamentally, but instead be a derivative entity emerging from non-spatiotemporal degrees of freedom. In the spirit of naturalised metaphysics, contributions to this volume consider the philosophical implications of this suggestion. In turn, philosophical methods and insights are brought to bear on the (...) foundations of quantum gravity itself. For instance, the idea of functionalism, borrowed from the philosophy of mind and discussed by several essays, exemplifies this mutual interaction the collection seeks to foster. (shrink)

According to no-futurism, past and present entities are real, but future ones are not. This view faces a skeptical challenge (Bourne 2002, 2006, Braddon-Mitchell, 2004): if no-futurism is true, how do you know you are present? I shall propose a new skeptical argument based on the physical possibility of Gödelian worlds (1949). This argument shows that a no-futurist has to endorse a metaphysical contingentist reading of no-futurism, the view that no-futurism is contingently true. But then, the no-futurist has to face (...) a new skeptical challenge: how do you know that you are in a no-futurist world? (shrink)

According to presentism, only the present exists. The view is in a bad dialectical situation since it has to face several objections based on physics and a priori arguments. The view remains nonetheless popular because it is, allegedly, more intuitive than alternative views, namely eternalism (past, present and future entities exist) and no-futurism (only past and present entities exist). In the essay, I shall not discuss whether intuitivity is an accurate criterion for ontological enquiry. I will rather argue that any (...) philosophically acceptable version of presentism entails highly counterintuitive consequences. Indeed, the presentist has to commit herself to substantial claims in order to provide an answer to two problems : the grounding problem and the cross-temporal relations problem. Therefore, if the main motivation for presentism is the willingness to stick with common sense intuitions, presentists should consider endorsing another view about existence in time. (shrink)

Neutral monism aims at solving the hard problem of consciousness by positing entities that are neither mental nor physical. Benovsky has recently argued for the slightly different account that, rather than being neutral, natural entities are both mental and physical by having different aspects, and then argued in favour of an anti-realist interpretation of those aspects. In this essay, operating under the assumption of dual-aspect monism, I argue to the contrary in favour of a realist interpretation of these aspects by (...) showing that the anti-realist interpretation collapses into neutral monism and that the realist interpretation is an interesting alternative. I close with a discussion of the realist interpretation of the aspects and its relation with panpsychism. (shrink)

« Pourquoi les choses tiennent-elles ensemble ? » (Traité d'ontologie, 2009, p. 237). Cette citation me sert de départ à une réflexion sur la nature des relations liantes souvent appelées relations de comprésence à la suite de Russell, ces bundling relations qui nouent les propriétés ensembles pour constituer les objets ordinaires (tables, chaises, individus biologiques) selon la théorie du faisceau. De même que Frédéric Nef, je suis séduit par les nombreuses vertus philosophiques de ces relations liantes. Ma contribution ne portera (...) pas sur une critique ou une défense de ces relations mais sur l'étude de leur nature, et en particulier, de leur possible nature méréologique. Je vais esquisser rapidement certains aspects de la théorie classique du faisceau que je qualifierai de réaliste pour opposer ensuite les variantes réalistes à deux autres versions méréologiques de la théorie, que je qualifierai d'éliminativistes.

As a candidate theory of quantum gravity, the popularity of string theory has waxed and waned over the past four decades. One current source of scepticism is that the theory can be used to derive, depending upon the input geometrical assumptions that one makes, a vast range of different quantum field theories, giving rise to the so-called landscape problem. One apparent way to address the landscape problem is to posit the existence of a multiverse; this, however, has in turn drawn (...) heightened attention to questions regarding the empirical testability and predictivity of string theory. We argue first that the landscape problem relies on dubious assumptions and does not motivate a multiverse hypothesis. Nevertheless, we then show that the multiverse hypothesis is scientifically legitimate and could be coupled to string theory for other empirical reasons. Looking at various cosmological approaches, we offer an empirical criterion to assess the scientific status of multiverse hypotheses. (shrink)

L'éternalisme implique une forme exotique d'éternité : toute entité, aussi éphémère soit-elle et quelle que soit sa localisation dans le temps, existe relativement à toute autre localisation temporelle. Cet essai vise, premièrement, à défendre l'éternalisme en exhibant les difficultés rédhibitoires du présentisme et du non-futurisme, et deuxièmement à examiner de quelle manière l'éternalisme pourrait être amendé à l'aune d'une affirmation que l'on trouve sous la plume de certains physiciens, à savoir que, fondamentalement, le temps n'existe pas. La disparition du temps (...) est-elle compatible avec la thèse éternaliste ? Enfin, en guise de conclusion, nous examinerons brièvement une conséquence curieuse de l'éternalisme : bien que mortels, nous sommes des êtres éternels. (shrink)

L'éternalisme, la thèse selon laquelle les entités que nous catégorisons comme étant passées, présentes et futures existent tout autant, est la meilleure approche ontologique de l'existence temporelle qui soit en accord avec les théories de la relativité restreinte et de la relativité générale. Cependant, les théories de la relativité restreinte et générale ne sont pas fondamentales si bien que plusieurs programmes de recherche tentent de trouver une théorie plus fondamentale de la gravité quantique rassemblant tous les enseignements de la physique (...) relativiste et de la physique quantique. Certaines de ces approches soutiennent que le temps n'est pas fondamental. Toutefois, si le temps n'est pas fondamental, quelles en sont les conséquences pour l'éternalisme et les débats sur l'existence dans le temps ? Premièrement, je soutiendrai que la non-fondamentalité du temps que l'on rencontre dans la théorie des cordes mène à l'éternalisme standard. Deuxièmement, je soutiendrai que la non-fondamentalité du temps rencontrée dans la gravité quantique à boucles implique l'éternalisme atemporel, à savoir une nouvelle position qui demeure fidèle à l'esprit de l'éternalisme standard.

La physique contemporaine pourrait bien nous livrer un enseignement incroyable, à savoir que l'espace et le temps n'existent pas fondamentalement.

Je soutiendrai ensuite qu'il est fructueux de prendre les différentes conceptions ontologiques de la conscience en philosophie de l'esprit en modèles pour la construction de solutions au problème de l'émergence de l'espace-temps.

La pertinence de la métaphysique analytique a fait l'objet de critiques : Ladyman et Ross, par exemple, ont suggéré d'abandonner ce domaine. French et McKenzie ont défendu la métaphysique analytique en affirmant qu'elle développe des outils qui pourraient s'avérer utiles pour la philosophie de la physique. Dans cet article, nous montrons dans un premier temps que cette défense heuristique de la métaphysique peut être étendue au domaine scientifique de l'ontologie appliquée, qui utilise des théories et outils issus de la métaphysique (...) analytique. Dans un deuxième temps, nous développons le parallèle que font French et McKenzie entre les mathématiques et la métaphysique pour montrer que l'ensemble du domaine de la métaphysique analytique, étant donné son utilité non seulement pour la philosophie mais également pour la science, devrait continuer à exister en tant que domaine largement autonome.

I begin by giving reasons to accept the block-universe view, the strongly supported by physics view that we live in a four-dimensional world. According to it, the past and the future are as real as the present. As a result, it seems that the future is determined in the sense that what will be the case will necessarily be the case. In the dissertation, I examine whether we have to accept this consequence. I show that we do not have to (...) bite the bullet: the future might be both real and contingent. I first start to consider modal realism (possible futures are real) as a possible solution. However, I propose then another account, actualist (positing the reality of only one possible world: the space-time we live in). This solution relies on a conventionalist theory about metaphysical modality (Sidelle, 1989). It states that modal modality is purely conventional. In combination with a realist interpretation of natural modality (causal and/or nomological), this framework allows me to propose that the future is conventionally closed and naturally contingent. In this view, the necessity of the future holds in virtue of linguistic conventions and then is conventionally necessary. But this is a distinct phenomenon from the natural contingency of the future: the future is naturally contingent because there are mind-independent probabilistic relations holding between the present and the future. This solution has strong consequences: most importantly, an anti-realist view about ordinary objects and physical particles. I end up by presenting and arguing in favour of the general image of the world that comes out from these views. (shrink)

La vieille question du statut ontologique du présent refait aujourd’hui surface au travers du débat qui oppose présentisme et éternisme. Les présentistes défendent la thèse selon laquelle seul ce qui est présent existe. Les éternistes soutiennent quant à eux que le présent ne jouit d’aucun privilège ontologique, les choses passées et futures existant tout autant que les choses présentes. Dans cet article nous ne chercherons pas à départager les protagonistes mais à écarter les théories dites « hybrides » qui prétendent (...) bénéficier des avantages de chacune des positions sans hériter de leurs inconvénients. Nous commencerons par retracer le débat entre présentisme et éternisme (section 1), puis nous présenterons les motivations des défenseurs des théories hybrides (section 2). Enfin, dans notre dernière section, nous avancerons un argument qui, s’il est juste, montre que les théories hybrides ne sont pas cohérentes. (shrink)

Les propriétés matérielles sont généralement appréhendées comme les propriétés d’une substance matérielle : cette chemise possède la propriété d’être bleue, cette chaussure la propriété d’être en bon état. Pourtant, on peut trouver plusieurs raisons de douter que les propriétés soient nécessairement les propriétés d’une substance matérielle, à la fois en métaphysique avec la théorie du faisceau, et en physique contemporaine à travers les notions d’énergie du vide et de champ. Or, si les propriétés ne sont pas les propriétés de substances (...) matérielles, on peut s’interroger sur la théorie de l’instanciation qu’implique une telle thèse. Dans cet essai, je m’emploierai à examiner la cohérence et la plausibilité de la thèse selon laquelle certaines, voir toutes les propriétés matérielles ne sont pas instanciées par une substance et la théorie de l’instanciation qui en découle. | : Material properties are generally construed as properties of material substances : this shirt has the property of being blue, these shoes are in good condition. However, one could think of several reasons to doubt that properties necessarily are properties of material substances both in metaphysics, with the bundle theory, and in contemporary physics, through the two notions of field and energy of the vacuum. But, if properties are not properties of material substances, what is the resulting theory of instantiation? Within the scope of this article, I will examine the consistence and plausibility of the view that several, if not all of, material properties are not instantiated by a substance and the theory of instantiation which follows from it.

Although the last decade has seen a proliferation of ontological approaches to arguments, many of them employ ad hoc solutions to representing arguments, lack interoperability with other ontologies, or cover arguments only as part of a broader approach to evidence. To provide a better ontological representation of arguments, we present the Arguments Ontology (ArgO), a small ontology for arguments that is designed to be imported and easily extended by researchers who work in different upper-level ontology frameworks, different logics, and different (...) approaches to argument evaluation. Unlike most ontological approaches to arguments, ArgO utilizes Basic Formal Ontology (BFO) as an upper-level ontology, and may be used alongside other commonly used ontologies in the BFO framework, including boththe Information Artifact Ontology (IAO), and the Information Entity Ontology (INFO). Critically, our proposal is principled, based on rigorous definitions and formal axioms out of which characterizations of arguments naturally fall. It is our hope that ArgO may assist researchers in many projects, including: integrating heterogeneous sources of evidence, structuring the content of semantic wikis, and enhancing semantic reasoning.

We present a set-theoretic model of the mental representation of classically quantified sentences (All P are Q, Some P are Q, Some P are not Q, and No P are Q). We take inclusion, exclusion, and their negations to be primitive concepts. It is shown that, although these sentences are known to have a diagrammatic expression (in the form of the Gergonne circles) which constitute a semantic representation, these concepts can also be expressed syntactically in the form of algebraic formulas. (...) It is hypothesized that the quantified sentences have an abstract underlying representation common to the formulas and their associated sets of diagrams (models). Nine predictions are derived (three semantic, two pragmatic, and four mixed) regarding people's assessment of how well each of the five diagrams expresses the meaning of each of the quantified sentences. The results from three experiments, using Gergonne's circles or an adaptation of Leibniz lines as external representations, are reported and shown to support the predictions. (shrink)

Many faith-based organizations, especially the Nigerian Baptist Convention, have deployed many means to promote peaceful coexistence in the society in an attempt to achieve Goal 16 of the Sustainable Development Goals of the United Nations. One such means is mediative dialogue through social media. As the world has metamorphosed digitally and social media changes communication means globally, using social media through mediative dialogue will likely improve promoting peaceful coexistence through mediative dialogue by faith-based organizations. The study examined how the Convention’s (...) pastors use social media to promote peaceful coexistence through mediative dialogue in Baptist churches within the Ibadan metropolis. The study was done through three qualitative research methods: sample surveys, semi-structured interviews, and document analysis. The study focused on Facebook, Twitter, WhatsApp, and Telegram. The study discovers that many Baptist pastors in Ibadan have been using at least one social media platform. The study is corroborated by reviewing other related literatures. Specific responses and reviews were also given on each of the focused social media platforms. The study is concluded by giving some recommendations to faith-based organizations generally and pastors of the Nigerian Baptist Convention specifically on how to deploy social media in the process of promoting peaceful coexistence in the society through mediative dialogue.

Baptism has been a focus of significant discussion in the ecumenical movement, as the different churches seek a common understanding of Baptism, with the goal of mutual recognition. The Orthodox Church has been involved in these conversations from the beginning. The present article is an attempt to trace the participation of the Orthodox representatives in these dialogues on Baptism, both at the level of the World Council of Churches and in bilateral dialogues. It explains the Orthodox understanding of Baptism as (...) a Sacrament, how this understanding is reflected (or not) in ecumenical agreements on Baptism. It will also review official Orthodox responses to some of these agreements. The author attempts to demonstrate that the Orthodox Church’s contributions to these sometimes-difficult dialogues have shown a commitment to seeking a common understanding of Baptism. Finally, this paper will examine the present state of ecumenical dialogue on Baptism, and evaluate its prospects for the future. (shrink)

The incommensurability thesis is the thesis that the content of some alternative scientific theories is incomparable due to translation failure between the vocabulary the theories employ. This paper presents an overview of the main issues which have arisen in the debate about incommensurability.

(...) On such a view. the content of theories may be compared on the basis of shared reference, despite failure of translation.

(ii) Hoyningen-Huenc’s neo-Kantian interpretation of Kuhn’s metaphysics. (shrink)

My paper provides reasons in support of the view that vague identity claims originate from a conflict between rigidity and precision in designation. To put this stricly, let x be the referent of the referential terms P and Q. Then, that the proposition “that any x being both a P and a Q” is vague involves that the semantic intuitions at work in P and Q reveal a conflict between P and Q being simultaneously rigid and precise designators. After having (...) shortly commented on an example of vague identity claim, I make the case for my proposal, by discussing how reference by baptism conflicts with descriptive attitudes towards understanding conceptual contents.

The ecumenical dialogue involves many ideas and attitudes. Within these theological discussions, Saint Cyprian of Carthage occupies his place. Most important, his vision about the Church has marked the entire Christianity. Because of this reason and for many others, this study attempts to explore his theological ideas regarding the limits of the Church, the validity of the Baptism outside the Church defined by her canonical limits. In order to accomplish this, we will have three important sections, as follows: 1. a (...) short biographical life; 2. the ecclesiological ideas of St Cyprian expressed in two important disputes of his time, namely the problem of the fallen and the Baptism professed outside the Church; 3. the limits of the Church in the thought of St Cyprian and the theological critics which we can share about this subject. Of course, our study will have some important conclusions. (shrink)

Stephen Palmquist is Professor of Religion and Philosophy at Hong Kong Baptist University. We invited him to answer the question "What norms or values define excellent philosophy of religion? as part of our "Philosophers of Religion on Philosophy of Religion" series. If we regard this as a philosophical (not a scientific) question, then the first step to answering it is to determine what norms or values define excellent philosophy, in general. Once that is established, we can inquire whether the nature (...) of religion brings with it any special features that make the task of doing excellent philosophy of religion unique. Unlike scientific explanations, excellent philosophical explanations must be multi-perspectival. A question that has only one right answer is not philosophical; instead, it is likely to be about facts. While we philosophers should care (deeply!) about any facts relevant to our inquiries, our peculiar way of interpreting facts means that answering a philosophical question cannot be done in one absolutely "right" way. This does not mean there are no right answers to philosophical questions; rather, there are many. But this does not make any answer equally good; for there would then be no such thing as excellent philosophy. The essentially perspectival nature of all genuinely philosophical questions means that the correctness of each purportedly "right" answer must be assessed in terms of its aptness for the perspective the questioner adopts when posing the question. A single question, such as "Does God exist?" can have many good answers, depending on whether the questioner assumes science, morality, aesthetics, or something else as the context. Each different type of inquiry has different boundary-conditions, so a good answer within each context is bound to differ from those in other contexts. Bad philosophy typically lacks depth: like a cyclops, its approach to answering questions is mono-perspectival. But if good philosophy acknowledges perspectives, what makes philosophy excellent? Good philosophy achieves excellence when it approaches a completeness whereby we begin to understand the range of relevant perspectives from which a given question can be asked, and the distinct boundary-conditions for answering it properly from each relevant perspective. Before applying this definition of excellent philosophy to the specific case at hand, we must pause to consider whether anything distinctive characterizes the range of philosophical topics and questions that typically come under the umbrella of philosophy of religion. In particular, does religion have features that make it especially difficult (or for that matter, easy) to think about philosophically, compared to other philosophical topics? Yes and no. (shrink)

The divine attributes of immensity and omnipresence have been integral to classical Christian confession regarding the nature of the triune God. Divine immensity and omnipresence are affirmed in doctrinal standards such as the Athanasian Creed (c. 500), the Fourth Lateran Council (1215), the Council of Basel (1431–49), the Second Helvetic Confession (1566), the Westminster Confession of Faith (1647), the Second London Baptist Confession (1689), and the First Vatican Council (1869–70). In the first section of this chapter, I offer a brief (...) historical overview of divine immensity and divine omnipresence in the Christian tradition. I then offer a brief taxonomy of contemporary models of divine omnipresence in the philosophical and theological landscape. In the second, more constructive section, I aim to gesture toward the retrieval of several classical insights regarding immensity and omnipresence that remain unexplored in contemporary analytic work.

In this study, I will analyse the position of the Orthodox Church(es) towards the ecumenical dialogue in accordance with the documents approved by the Synod of Crete (2016), but also with the social document For the Life of the World of the Ecumenical Patriarchate (2020). After a brief presentation of the important moments of the historical journey for the meeting of the Synod, I will present the most important internal and reception issues of it. In the following, I will present (...) the reason for the publication of the social document and the relation with the Synod of Crete. In the last part of the study, I will deal critically with a theological synthesis on the following topics: ecclesiological self-identity, Trinitarian baptism, the quality of being a Christian, the Orthodox Church and the Churches, ecumenism for dialogue, for witnessing, and cooperation. Of course, in the end, I will present the most important conclusions. (shrink)

In the Romanian Orthodox theology, the words mission and pastoral care are used very often in a mixed way. Nevertheless, there are some differences between them and we explain why. In the main part of our article, we demonstrate that the biblical verse regarding the great commandment for mission was translated in a wrong way and it gave a different paradigm for mission. In the second part, we speak about catechesis and catechumenate at the beginning of the Church and about (...) the present situation regarding these activities. In the last part, we analyze what happens around the Holy Sacrament of Baptism when we speak about mission or pastoral care. In consequences, this article presents some conclusions which can be applied in the life and activity of the Romanian Orthodox Church. (shrink)

In the thesis I present a novel theory of semantic reference, which I call the coordination view of semantic reference. In chapter one I develop a novel theory of conventions, which I call the coordinating rule view of conventions. On the coordinating rule view, roughly, a convention is a rule which originates in a meta-coordination game and is adopted in order to deal with a series of future coordination games. This view is Lewisian in spirit, but rejects Lewis’s view that (...) a convention is a regularity in behaviour. In chapter two I use the coordinating rule view of conventions in order to define the coordination view of semantic reference. On the coordination view, roughly, a name N semantically refers to a particular o if, and only if, there is a convention to use N to speaker-refer to o. I also argue that a consideration of the coordination view of semantic reference makes it plain that Kripke’s causal theory has no non-trivial explanatory content. The causal chain that exists between a baptism and downstream use of a name comes about in virtue of the fact that knowledge of the content of a convention is typically causally acquired. This fact, however, is a mere triviality about conventions as such, not a revelation about reference. I also argue that non-Kripkean versions of causalism have little to recommend them. In chapter three I compare the coordination view of semantic reference with the traditional descriptivism of Russell and Frege. I defend the claim that traditional descriptivism is plainly false. This follows from the commitment of the traditional descriptivists to what I call eccentricity about names, i.e. the view that the descriptive condition which the utterer of the name associates with the name determines the semantic reference of the name. In fact, I claim that traditional descriptivism is so plainly false that we need to explain why Russell and Frege proposed it. I try to provide such an explanation. In chapter four I address various issues raised by the discussion in the previous three chapters. The main claim defended is that it is very strange that nothing like the coordination view of semantic reference features in discussion concerning semantic reference, given that the analogous view of sentence meaning, i.e. the view that sentence meaning is to be defined in terms of speaker-meaning and convention, has received a lot of attention.

Fizik disiplininde astronomiye yönelik sorular Johannes Kepler (1571-1630) ve Isaac Newton (1643-1727) gibi fizik alanında devrim yaratan düşüncelerin ortaya çıkmasına yol açmıştır. Kepler ‘Yeni Astronomi’ (Astronomia Nova), ‘Dünya'nın Uyumu’ (Harmonice Mundi) ve ‘Kopernik Astronomisinin Özeti’ (Epitome Astronomiae Copernicanae) adlı çalışmalarından hareketle ileri sürdüğü gezegensel hareket yasaları, Newton ise 1687 yılında yayımlanan ‘Doğa Felsefesinin Matematiksel İlkeleri’ (Philosophiae Naturalis Principia Mathematica) isimli çalışmasında yer verdiği hareket yasaları ile fizik disiplininde Aristoteles fiziğinin terk edilerek yeni bir fizik anlayışının ortaya çıkmasına ve böylece fizik (...) alanında bir devrimin meydana gelmesine sebep olmuşlardır. Fizik disiplininde gerçekleşen bu devrimin bir benzeri ise canlıların çalışılması ya da biyoloji disiplini söz konusu olduğunda 1800’lerden biraz daha geç bir zamana rastlamaktadır. Biyolojide gerçekleşen devrimsel düşünce doğal seçilim mekanizması ile canlılarda zaman içerisinde gerçekleşen değişim ve dönüşüm sürecini açıklayan Charles Darwin’in evrim kuramına yönelik görüşlerini ortaya koymasına tekabül etmektedir. Bu kapsamda çalışmada öncelikli olarak canlılarda meydana gelen değişim süreçlerine yönelik tespitleri ile Darwin’in görüşlerinin olgunlaşmasına katkıda bulunan Fransız Transformistler (Dönüşümcüler) olarak da bilinen Georges-Louis Leclerc (Comte de Buffon), Jean-Baptiste Lamarck ve George Cuvier’in görüşlerine yer verilmektedir. Ardından bu bilim insanlarının canlılardaki dönüşümsel ya da evrimsel değişime ilişkin argümanlarının Darwin’in evrim kuramını nasıl etkilediği ve bu etkilerin sonucunda biyoloji biliminde nasıl bir devrimin ortaya çıkmasına yardımcı oldukları aktarılmakta ve bu çerçevede Darwin’in on dokuzuncu yüzyılda biyoloji biliminde devrime yol açan tespitlerine ve evrim kuramının ayrıntılarına yer verilmektedir.
