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)

O presente trabalho pretende analisar as relações entre loucura e obra no jovem Foucault, isto é, no Foucault dos anos 1950 que realiza seu curso sobre antropologia (La Question Anthropologique) em Lille e na ENS entre 1952 (ou 1951) e 1955. Para estabelecer o problema, o texto começa com uma contextualização inicial sobre os inéditos de Foucault disponibilizados desde 2013 na BNF. Então o texto constrói o problema a partir de comentadores (especiamente Jean-Baptiste Vuillerod) e encontra na figura (...) de Karl Jaspers um interlocutor importante, em torno do qual Foucault gira para estabelecer suas próprias posições. Jaspers, psiquiatra e filósofo, contém teses sobre a loucura, a obra e a civilização diretamente ligadas aos interesses do jovem Foucault. Tanto a leitura de Jaspers sobre Nietzsche, quanto a das relações entre loucura e obra, serão importantes para o jovem Foucault, pois é por meio de Jaspers - dentre outros - que uma psicologia da loucura e da obra (seja qual for seu paradigma) desemboca na análise de figuras como Maurice Blanchot, na leitura singular que Foucault faz de Nietzsche e nos problemas que o levarão a uma história da loucura. *** *** -/- This article aims to analyze the relation between madness and work (oeuvre) in the “young Foucault”, focusing on the Foucault’s lessons of Anthropology taken in Lille and at the ENS between 1952 (or 1951) and 1955, under the title La Question Anthropologique. In order to place this problem, the text begins with an initial contextualization of Foucault’s unpublished works, only made available since 2013 at Bibliothèque Nationale de France. Then the article passes to the question of the madness and work according to some commentators (especially Jean-Baptiste Vuillerod) and finds in the figure of Karl Jaspers an important author, whose reference serves for Foucault to compose his own positions. Jaspers, psychiatrist, and philosopher, contains theses on madness, work and civilization directly linked to the interests of the young Foucault. Both Jaspers’ reading of Nietzsche and considerations about madness and work will be important for the young Foucault, as it is through Jaspers (among others) that the psychological and existential positions on madness and work leads Foucault to the analysis of figures like Maurice Blanchot, to his own reading of Nietzsche and the problem of a history of madness.

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.

RENÉ DESCARTES: UMA BIOGRAFIA -/- RENÉ DESCARTES: A BIOGRAPHY -/- Emanuel Isaque Cordeiro da Silva - CAP-UFPE, IFPE-BJ e UFRPE. E-mails: [email protected] e [email protected]. WhatsApp: (82)98143-8399. -/- -/- Nascido em 1596 em Haia, nas fronteiras de Touraine e Poitou, em uma família nobre, René Descartes vem ao mundo ao mesmo ano em que Johannes Kepler (1671-1630), em seu primeiro trabalho publicado (Mysterium cosmographicum), prova a superioridade da astronomia moderna (a de Nicolau Copérnico (1473-1543)) da astronomia antiga (a de Ptolomeu (90-168 (...) d.C.)). Ao mesmo tempo, Galileu Galilei (1564-1642), que detém a cadeira de matemática da Universidade de Pádua, funda o método experimental. As descobertas de Galileu tiveram forte impacto sobre o Colégio Real de La Fleche, realizado pelos jesuítas e onde Descartes recebeu, a partir de 1606, uma forte educação. Ele menciona, no Discurso do Método, seu “desejo extremo” em aprender, seguido, no final de seus estudos, de uma grande decepção: decepção com a filosofia ensinada, cujas controvérsias perpétuas revelam um caráter questionável, e que não pode fornecer um alicerce, em seu estado atual, para outras ciências. Também é proferido um desapontamento, mas esse desapontamento é inverso e diz respeito às matemática, capaz de fornecer esse fundamento que a filosofia não confere, mediante sua certeza e evidências, mas sobre o qual ainda não construímos nada. -/- -/- Numa Europa marcada pelo choque do tradicionalismo católico e do mercantilismo protestante, o lento declínio do poder espanhol e a luta dos Países Baixos pela sua independência, Descartes escolheu, primeiramente, após a graduação, a carreira militar. Engajado no exército do Príncipe Maurício de Nassau, ele é retirado da ociosidade da vida da guarnição pelo encontro, em 1618, de um jovem cientista holandês, Isaac Beeckman (1588-1637), que se tornou seu amigo íntimo por algum tempo. Conhecedor de todas as pesquisas científicas do momento e partidário da nova concepção “mecanicista” da natureza, Beeckman compartilhou com Descartes um entusiasmo que foi acompanhado, segundamente, da ambição de realizar a ciência universal por si mesma, mediante um método único: na noite de 10 de novembro de 1619, ele concebe em três “sonhos”, “os alicerces de uma ciência admirável”. -/- Nos anos seguintes a essa iluminação decisiva, Descartes viajou por toda a Europa, estimando, como Michel de Montaigne (1533-1592), que a demonstração de boas maneiras e costumes diferentes podem gerar muitos preconceitos. Toda sua vida, além disso, esteve vagando, isto é, foi marcada por múltiplas mudanças de residências, e a recusa de estabelecer um vínculo muito de perto com alguém. Foi na Holanda que ele, finalmente, buscará a tranquilidade que não encontrara na França ainda abalada pelas guerras religiosas, antes de ser assim pelas convulsões da Fronda. Todavia, mesmo na Holanda, ele não pôde evitar os ataques de calvinistas e polemicas teológicas que o repugnaram, como evidenciado em suas discussões com a Universidade de Utrecht entre 1643 à 1645 e a Universidade de Leiden em 1647. -/- -/- Além de sua amizade com Beeckman, outro encontro teve uma influência indubitavelmente decisiva sobre o destino de Descartes: o encontro com o cardeal de Bérulle. Fundador da congregação do Oratório (ao qual pertencem Nicolas Malebranche (1638-1715) e Jean-Baptiste Massillon (1663-1742)), o cardeal de Bérulle enxerga na nova física mecanicista, um meio de lutar contra o naturalismo resultante do Renascimento e seu paganismo latente: em uma longa entrevista com Descartes, no outono de 1647, ele fez dessa última uma obrigação de consciência para se dedicar, nesse sentido, à filosofia. -/- Em 1628, Descartes começa a escrever as Regras para a direção do espírito, um tratado inacabado e que não foi publicado durante a vida do autor. Em 1631, desenvolvera a geometria analítica que combina curvas geométricas com equações algébricas. Em 1633 escreveu O Tratado do Homem e preparava-se para publicar O Tratado do Mundo quando a notícia da condenação de Galileu Galilei pelo Santo Ofício (a Inquisição) o deixou receoso e decide, por prudência, não publicar o seu Tratado no qual a tese do movimento da Terra ao redor do Sol é apoiada. Alguns anos depois, foi divulgado em público cultivada de algumas de suas descobertas científicas: além da geometria, a dioptria (a teoria da refração da luz) e meteoros (teoria dos fenômenos atmosféricos luminosos). Esses três tratados aparecem no apêndice do Discurso do Método, e como “ensaios” desse método, em 1637. No século XIX, Victor Cousin (1792-1867) publicou pela primeira vez o Discurso sozinho, sem os ensaios. -/- Então vem a principal obra de Descartes no ramo da metafísica: as seis Meditações, aumentadas pelas objeções dos mais famosos filósofos da época (incluindo Thomas Hobbes (1588-1679), Antoine Arnauld (1612-1694) e Pierre Gassendi (1592-1655)), e as respostas a essas objeções, apareceram em 1641. Ansioso para expor sua filosofia para que pudesse ser ensinada, ele também a caracteriza em forma de manual com os Princípios da Filosofia de 1644. -/- Além dos trabalhos publicados, foi por meio das cartas trocadas com personalidades do mundo erudito que Descartes encontrou a oportunidade de esclarecer vários pontos de sua filosofia. Seus principais correspondentes foram o Prade Marin Mersenne (1588-1648), o Padre Denis Mesland (1615-1672), Pierre Chanut (1601-1662), Claude Clerselier (1614-1684), Christiaan Huygens (1629-1695) e Henry More (1614-1687). A partir de 1643, Descartes sustentou, com a Princesa Isabel da Boêmia (1596-1662), uma correspondência dedicada essencialmente a questões morais, que lhe permitiu a formulação de suas ideias nesse campo: esse esforço conduziu, em 1649, ao tratado das Paixões da alma. -/- Nesse mesmo ano, 1649, a Rainha Cristina da Suécia (1626-1689) o convida para ir a Estocolmo, que ele aceitou após muita hesitação. Recebido com todas as honras, mas forçado a um modo de vida bastantemente distinto daquele que era acostumado, e submetido a um clima do qual não se adequou, ele sucumbiu a pneumonia em fevereiro de 1650. -/- Descartes deixou-nos uma espécie de autobiografia intelectual na primeira parte do Discurso do Método: em seus anos de treinamento, seus entusiasmos e suas decepções. O discurso é, também, o primeiro livro para quem busca compreender o projeto filosófico cartesiano desde sua gênese até sua realização. Existem expostos, o método claro (na segunda parte), mas também a moral (terceira parte), a metafísica (quarta parte) e finalmente a física (quinta e sexta partes). (shrink)

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.

Supra-Bayesianism is the Bayesian response to learning the opinions of others. Probability pooling constitutes an alternative response. One natural question is whether there are cases where probability pooling gives the supra-Bayesian result. This has been called the problem of Bayes-compatibility for pooling functions. It is known that in a common prior setting, under standard assumptions, linear pooling cannot be nontrivially Bayes-compatible. We show by contrast that geometric pooling can be nontrivially Bayes-compatible. Indeed, we show that, under certain assumptions, geometric and (...) Bayes-compatible pooling are equivalent. Granting supra-Bayesianism its usual normative status, one upshot of our study is thus that, in a certain class of epistemic contexts, geometric pooling enjoys a normative advantage over linear pooling as a social learning mechanism. We discuss the philosophical ramifications of this advantage, which we show to be robust to variations in our statement of the Bayes-compatibility problem. (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.

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)

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)

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)

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)

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.

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. (shrink)

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)

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)

Est-il possible de parler de ce qui n’est pas ou d’y penser sans présupposer une forme d’être pour cela même que nous pensons ne pas exister?

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)

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)

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)

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)

First recorded in the 14th century, the analogy of spit-roast meat argues that expecting the Sun to rotate around a strictly immobile Earth would be just as ludicrous as trying to move the fire around the roasting meat. On the contrary, it should be the Earth that spins upon itself in order to glean, from all possible angles, all the benefits of the Sun, just as it is the meat’s responsibility to turn on the spit before the motionless fire for (...) it to be perfectly cooked on all sides. Aimed at demonstrating, in geocentricism, the plausibility of the rotation of the Earth and, in heliocentrism, at supporting the physical reality of this terrestrial rotation, nowadays this analogy barely elicits more than an amused, or even condescending, smile. However, its continued long-term existence and its frequency of use — from the 14th to the 19th century, we found it mentioned by no less than 45 different authors — incited us to finally pay attention to it. We then noticed that beyond its explicitly cosmological scope, it raises, in its own way, the question of the purpose of the natural world: had the latter been conceived based upon humankind, then it is normal, despite what this analogy advocates, that the Sun is at the service of something more important than itself by rotating, to the profit of humankind, around the Earth; conversely, since such an infringement of the rule of common sense, as illustrated by this analogy, can neither be justified nor tolerated, it is up to the Earth to move around the Sun. Tracing the vicissitudes of this analogy, over 6 centuries, is thus not only about reconstructing the largely forgotten history of a presently obsolete analogy, but also about discovering the deeper meaning, henceforth incomprehensible, behind it. In describing how this meaning became progressively lost, one can finally pro­vide an understanding of why, in the present day, we are no longer capable of more than an amused smile when happening upon it! (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)

The metaphysics of quantum gravity is a relatively small and new research field, and thus as of now, its focus has been on explaining how spacetime could emerge from a more fundamental and non-spatiotemporal ontology. Consequently, this entry is equally focused on questions regarding the status of spacetime and spacetime emergence. Section 1 situates the field within metaphysics of science more broadly. Sections 2 and 3 investigate, respectively, the status of spacetime in different approaches to quantum gravity and a number (...) of potential issues with its lack of fundamentality. The entry covers then the nature of the emerging spatiotemporal ontology (Section 4) and the building relation relating it to the non-spatiotemporal ontology (Section 5). Section 6 surveys various potential applications of spacetime emergence of a number of debates in metaphysics. (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)

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)

« 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.

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)

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)

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.

Worldwide populations are aging with economic development as a result of public health initiatives and advances in therapeutic discoveries. Since 1850, life expectancy has advanced by 1 year for every four. Accompanying this change is the rapid development of anti‐aging science. There are three schools of thought in the field of aging science. One perspective is the life course approach, which considers that aging is a good and natural process to be embraced as a necessary and positive aspect of life, (...) where the aim is to improve the quality of existing lifespan and “compress” morbidity. Another view is that aging is undesirable, and that rejuvenation and indeed immortality are possible since the biological basis of aging is understood, and therefore, strategies are possible for engineering negligible senescence. Finally, a hybrid approach is that life span can be extended by anti‐aging medicines but with uncertain effects on health. While these advances offer much promise, the ethical perspectives are seldom discussed in cross‐disciplinary settings. This article discusses some of the key ethical issues arising from recent advances in biogerontology. (shrink)

La physique contemporaine pourrait bien nous livrer un enseignement incroyable, à savoir que l'espace et le temps n'existent pas fondamentalement. Je présenterai succinctement les ontologies suggérées par les deux principaux programmes de recherche en gravité quantique : la théorie des cordes et la gravité quantique à boucles. 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.

This summary is not exactly the way I would have done it myself but I must admit that my writing is sometimes a challenge to read. So I asked an AI to do this summary expecting that it will give an easily understandable although not totally accurate view on Ontology of Knowledge and from this general understanding help the reader to read the original papers. Jean-Louis Boucon’s works, "Introduction to the Ontology of Knowledge" and "Time, Space, and World as (...) Knowledge," delve into the intricate nature of reality, meaning, and the process of knowing. Boucon challenges traditional dichotomies in philosophy and science, presenting a cohesive framework where the knowing subject and the world are intertwined aspects of a single dynamic reality. His ideas provide a robust foundation for exploring ontological and epistemological questions, including the interpretation of quantum mechanics. (shrink)

It is popular to hold that emotions are evaluative. On the standard account, the evaluative character of emotion is understood in epistemic terms: emotions apprehend or make us aware of value properties. As this account is commonly elaborated, emotions are experiences with evaluative intentional content. In this paper, I am concerned with a recent alternative proposal on how emotions afford awareness of value. This proposal does not ascribe evaluative content to emotions, but instead conceives of them as evaluative at the (...) level of intentional mode or attitude. I first argue that this proposal fails to make emotions intelligible as value apprehensions. There are reasons to suppose that emotions do not apprehend value to begin with, but are related to values in a different, non-epistemic sense. I then go on to show that the notion of an evaluative intentional mode can still help elucidate the evaluative character of emotion. I argue that there is a plausible non-epistemic understanding of the view that emotions are evaluative modes. On this account, emotions are not ways of apprehending values, but ways of acknowledging values. (shrink)

It is popular to hold that our primary epistemic access to specific response-dependent properties like the fearsome or admirable (or so-called ‘affective properties’) is constituted by the corresponding emotion. I argue that this view is incompatible with a widely held meta-ethical view, according to which affective properties have deontic force. More specifically, I argue that this view cannot accommodate for the requirement that deontic entities provide guidance. If affective properties are to guide the formation of the corresponding emotion, our primary (...) access to them cannot be provided by that same emotion. (shrink)

Deux idées centrales sont défendues dans cet article. La première concerne les liens entre les concepts de matérialisme émergentiste et de réalisme critique dans la métaphysique bungéenne. Je défends la thèse que le réalisme critique bungéen doit intégrer épistémologiquement celui de matérialisme afin de se développer en tant que doctrine méthodologique. J’y analyse ce que je considère être les fondements de la méthode de la construction de cette même métaphysique, soit l’affirmation du postulat de l’extériorité du monde concret et son (...) rôle dans la méthode en question. La seconde thèse a pour objet une analyse de cette méthode au moyen de l’étude que j’y fais des concepts ontologiques bungéens d’objet, de substance et de propriétés objectales. Je compare ensuite cette méthode à certains aspects de la philosophie des mathématiques et en particulier au rôle attribué dans cette même philosophie à la méthode axiomatique en tant que méthode de construction théorique et de preuve. Je conclus en une certaine circularité de l’argument qui justifie le réalisme critique à partir du postulat ontologique de l’extériorité du monde concret. (shrink)

A prominent version of emotional cognitivism is the view that emotions are preceded by awareness of value. In a recent paper, Jonathan Mitchell (2019) has attacked this view (which he calls the content-priority view). According to him, extant suggestions for the relevant type of pre-emotional evaluative awareness are all problematic. Unless these problems can be overcome, he argues, the view does not represent a plausible competitor to rivaling cognitivist views. As Mitchell supposes, the view is not mandatory since its core (...) motivations can be accommodated by competing views, too. I argue that Mitchell's case against the content-priority view is unconvincing as it misconceives the principal motivation for the view. As I show, properly reconstructed, this motivation provides a strong case for the indispensability of the view to any adequate cognitivist treatment of emotion. Moreover, Mitchell's survey of candidates for pre-emotional value awareness can be seen to rest on problematic phenomenological assumptions. (shrink)

The aim of this paper is to clarify the role of category theory in the foundations of mathematics. There is a good deal of confusion surrounding this issue. A standard philosophical strategy in the face of a situation of this kind is to draw various distinctions and in this way show that the confusion rests on divergent conceptions of what the foundations of mathematics ought to be. This is the strategy adopted in the present paper. It is divided into 5 (...) sections. We first show that already in the set theoretical framework, there are different dimensions to the expression foundations of. We then explore these dimensions more thoroughly. After a very short discussion of the links between these dimensions, we move to some of the arguments presented for and against category theory in the foundational landscape. We end up on a more speculative note by examining the relationships between category theory and set theory. (shrink)
