In this paper I sketch the evolution of the main theories of the relationship between time and motion from Descartes to Newton, by defending an hypothesis that traces back Newton’s realism about time to Barrow’s “metric realism”, which Newton developed as the claim that measuring a magnitude X implies that X exists independently of our measures.

Comment pouvons-nous analyser des relations de valeur non standards, comme la parité axiologique, en termes d’attitudes appropriées? Wlodek Rabinowicz suggère que deux choses sont à parité si et seulement si il est à la fois permissible de préférer l’une à l’autre et permissible d’avoir la préférence contraire. Dans un article récent, Johan Gustafsson soutient toutefois que l’analyse de Rabinowicz viole un principe de symétrie entre valeurs et préférences, selon lequel il existe pour toute relation de valeur une relation de préférence (...) correspondante (et vice-versa). À la lumière de ce principe, Gustafsson propose une analyse alternative, selon laquelle deux choses sont à parité si et seulement si il est requis d’entretenir ces choses en parité préférentielle. Dans cet article, j’examine en détail les arguments avancés par Gustafsson contre l’analyse de Rabinowicz et je montre qu’aucun d’eux n’est convaincant. (shrink)

Nel contributo, partendo da una prospettiva teoretica, ci si prefigge di analizzare i rapporti fra la filosofia indiana di Śaṃkara (il massimo filosofo del Vedānta, vissuto nell’VIII sec. d. C.) e il pensiero di Bergson. Da un simile punto di vista diviene infatti possibile una riflessione critica e interpretativa sui testi dei due autori, utile a chiarire alcuni problemi ermeneutici del pensiero śaṃkariano. Reciprocamente, la conoscenza del pensiero di Śaṃkara permette di illuminare e chiarire aspetti problematici della filosofia bergsoniana, in (...) particolare il rapporto fra materia e memoria e l’autentico significato di élan vital. Il saggio utilizza il concetto di advaita (non-dualità) - uno degli elementi chiave della filosofia vedantica – verso un superamento del dualismo materia/spirito, così come è stato affrontato anche dal filosofo francese nel xx secolo. Per svolgere questa interpretazione si approfondiscono poi i concetti di coscienza nei due filosofi, e la nozione di brahman-ātman intesa come trascendentale “non kantiano”, nella logica di smarcamento dalla prospettiva kantiana che era l’obiettivo dichiarato fin dai primi sviluppi della filosofia bergsoniana, contenuti nell’opera del 1889, Saggio sui dati immediati della coscienza.

L’identité et la datation de Nicolas le Péripatéticien, l’auteur d’un sommaire de la philosophie d’Aristote, ont fait l’objet d’un article récent de Silvia Fazzo paru dans la Revue des Études Grecques. Contre la datation courante, fondée sur l’identification de Nicolas à l’historien de grand renom Nicolas Damascène , Fazzo a montré que Nicolas avait probablement vécu au cours de la période couvrant les IIIe au Ve siècles ap. J.-C., et plus problablement à l’époque de l’empereur Julien l’Apostat . Cette hypothèse (...) trouve un appui dans un nouveau fragment en traduction hébraïque découvert par Mauro Zonta, dans lequel Nicolas cherche à expliquer la Trinité de Dieu au moyen de la doctrine aristotélicienne des causes: Dieu est un, en tant que sa substance est une, mais Dieu est également trois, puisqu’il est à la fois causes motrice, formelle et finale du monde. Dans la mesure, évidemment réduite, où un fragment si court est susceptible de datation, l’époque de Julien paraît la plus probable. (shrink)

Bios Philosophos. Philosophy in Ancient Greek Biography (Brepols, 2016), organized by Mauro Bonazzi and Stefan Schorn, delivers deep and wide tours through the philosophical aspects of Greek biographical production. On the one hand, it does not concentrate only on the later periods of Greek philosophy, when biographical production abounded; instead, it goes all the way back to the fourth century BCE, when biographical texts were fragmentary and mingled with other styles. On the other, it tries to unveil the philosophical (...) motives in authors' works who tend to be disregarded as historians, biographers, hagiographers, or even as mere fans of the most prominent figures of their own schools. -/- In our review, we will attempt to give a brief account of the ten articles that make up this volume, which, in turn, will hopefully provide an overview of the different connections between the biographies and biographers and their philosophical motives.

Antes de entrar cuidadosamente no estudo de cada filósofo, em suas respectivas ordens cronológicas, é necessário dar um panorama geral sobre eles, permitindo, de relance, a localização deles em tempos históricos e a associação de seus nomes com sua teoria ou tema central. l. OS FILÓSOFOS PRÉ-SOCRÁTICOS - No sétimo século antes de Jesus Cristo, nasce o primeiro filósofo grego: Tales de Mileto2 . Ele e os seguintes filósofos jônicos (Anaximandro: Ἀναξίμανδρος: 3 610-546 a.C.) e Anaxímenes: (Άναξιμένης: 586-524 a.C.) tentaram (...) expressar/elucidar o que é a arché, ou constitutivo fundamental do Universo. 4 Também sobressaem as teorias de Pitágoras (Ὁ Πυθαγόρας: 570 a.C.- 495 a.C.), completas de misticismo e Matemática; a de Heráclito (Ἡράκλειτος ὁ Ἐφέσιος: 540-470 a.C.), o filósofo do devir e o de seu oponente, Parmênides (Παρμενίδης: 530-460 a.C.), que elucida a primeira teoria do ser, e para qual é alcunhado como o iniciador da Metafísica. Anaxágoras (Ἀναξαγόρας: 500 a.C.- 428 a.C.) esboça uma teoria sobre o Nous, o espírito divino. Por outro lado, Demócrito (Δημόκριτος: Grécia: 460-370 a.C.) e Empédocles (Ἐμπεδοκλῆς: 490 a.C.-430 a.C.) insistem no materialismo. Em contrapartida, os sofistas (Parmênides, Cálicles (Καλλικλῆς: personagem platônico cuja existência é duvidosa) e Górgias (Γοργίας: 485 a.C.-380 a.C.)) gozam das suas aptidões à dialética, e colocam o relativismo como uma posição filosófica. Sócrates será o inimigo mais temível dessa posição. Este é o começo do movimento filosófico de Atenas, que culmina nos séculos quinto e quarto, tal qual, posteriormente, veremos. 2. O APOGEU GREGO – Sócrates (Σωκράτης: 469 a.C.-399 a.C.), Platão (Πλάτων: 428/427- 348/347 a.C.) e Aristóteles (Ἀριστοτέλης: 384 a.C.-322 a.C.) formam o triunvirato dos grandes filósofos gregos. O primeiro (Sócrates), com seu método "maiêutico" e sua teoria do conceito; o segundo (Platão), com sua teoria das ideias e seu estilo literário (dialogista); e o terceiro (Aristóteles), com a estruturação dos principais ramos filosóficos, como a Lógica, a Metafísica, a Ética, a Psicologia racional e a Política; todos eles elevaram a Filosofia para um posto de primeira ordem. Doravante, todos os filósofos tornam-se credores das contribuições desses gênios. Em certos autores, é clara a influência de Platão ou de Aristóteles. Sendo que, ambos os filósofos, tiveram influência absoluta de Sócrates, uma vez que Platão fora seu discípulo, e Aristóteles discípulo de Platão. A Idade Média, por exemplo, foi toda ela, em sua gênese e desenvolvimento, alicerçada no pensamento e nas ideias platônicas; tal era histórica é caracterizada pela luta em favor de um ou de outro autor; o platonismo tomou precedência nos primeiros séculos do cristianismo; somente após o décimo século Aristóteles foi redescoberto. 3. A FILOSOFIA CRISTÃ MEDIEVAL - Santo Agostinho (354 a.C.-430 a.C.) se destaca, no quinto século, com sua teoria da iluminação e a aplicação da teoria platônica ao Cristianismo. No século XIII, São Tomás de Aquino (1225-1274), sintetiza Aristóteles com o Cristianismo. Os dois autores formam o núcleo da filosofia cristã em seus respectivos séculos. A escolástica teve seu tempo de decadência. Se mencionam, principalmente, dois autores: João Duns Escoto (1266-1308) e Guilherme de Ockham (1285-1347). O primeiro é o "Doutor Sutil ", e o segundo cai em um fideísmo e um nominalismo, para todos os conceitos criticáveis. Em uma segunda parte, tentaremos explicar os respectivos pensamentos dos autores mencionados, e outros que pertencem ao mesmo tempo, antigos e medievais. Naquela época, a Filosofia era puramente realista, aplicada ao mundo e ao homem. Somente na Idade Moderna, a Filosofia assumirá o problema do conhecimento como a base e o começo de todo filosofar. 4. A FILOSOFIA RACIONALISTA (MODERNA) - Na Idade Moderna, sobressai o racionalismo de Descartes (1596-1650) prolongado, então, com Malebranche (1638-1715) (ocasionalismo), Espinosa (1632 -1677) (panteísmo) e Leibniz (1646-1716) (teoria das mônadas). Estamos nos séculos XVII e XVIII. A atenção será focada nas disputas filosóficas da corrente empirista contra a racionalista. 5. A FILOSOFIA EMPIRISTA – O empirismo é florescido, principalmente, na Inglaterra. Francis Bacon (1561-1626), primeiro, e depois Locke (1632-1704) com sua rejeição de ideias inatas, Berkeley (1685-1753) com postura e ideias paradoxais, também idealistas e Hume (1711-1776), com suas famosas críticas contra o princípio da causalidade e o conceito de substância, são os principais autores. 6. KANT E OS IDEALISTAS ALEMÃES - Como a tentativa de sintetizar o racionalismo e empirismo, está a teoria de Kant (1724-1804), no século XVIII. Para o seu gênio seguido pelos três idealistas alemães mais importantes: Fichte (1762-1814) (idealismo subjetivo), Schelling (1775-1854) (idealismo objetivo) e Hegel (1770-1831) (idealismo absoluto). Esses Autores representam o ápice da especulação filosófica. A análise, a profundidade, a complexidade da expressão e o espírito sistemático são as características do gênio alemão idealista. 7. OS FILÓSOFOS DO SÉCULO XIX - Antes de tudo, é necessário mencionar, no século dezenove, aos dois grandes críticos de Hegel, que são Kierkegaard (1813-1855) (precursor do existencialismo) e Marx (1818-1883) (com seu materialismo dialético). O próximo é outro casal: Nietzsche (1844-1900) (teoria do Super-homem) e Schopenhauer (1788-1860) (com seu absoluto pessimismo). Comte (1798-1857) com sua doutrina positivista, completará o quadro desses filósofos. Numa outra oportunidade, vamos desmembrar sobre o pensamento e principais ideias acerca desses autores. 8. OS FILÓSOFOS DO SÉCULO XX - Antes de tudo, há um autor que iluminou a filosofia do século XX: Edmund Husserl (1859-1938), fundador do método fenomenológico. Em seguida, existem dois fluxos que são derivados diretamente de Husserl, a saber, o existencialismo e a axiologia. Dentro da corrente axiológica, estudaremos Scheler (1874-2928). Por outro lado, o existencialismo tem quatro autores principais; dois são alemães: Heidegger (1889-1976) e Jaspers (1883-1969); e os demais são franceses: Sartre (1905-1980) e Marcel (1889-1973). Heidegger insiste em que seu tema tratado em sua filosofia não é a unicidade do homem, mas o ser em geral. Jaspers é famoso por seu conceito de transcendência (Deus). Sartre é um antiteísta sincero, e seu existencialismo é definido como um pensamento que assume todas as consequências da negação de Deus. Em contraste, Gabriel Marcel é um filósofo Católico, que conseguiu uma análise profunda das situações humanas, que aparecem em íntima concordância com as verdades cristãs. Vamos terminar com Russell (1872-1970), autor básico do positivismo lógico.

While growing empirical evidence suggests a continuity between human and non-human psychology, many philosophers still think that only humans can act and form beliefs rationally. In this paper, we challenge this claim. We first clarify the notion of rationality. We then focus on the rationality of beliefs and argue that, in the relevant sense, humans are not the only rational animals. We do so by first distinguishing between unreflective and reflective responsiveness to epistemic reasons in belief formation and revision. We (...) argue that unreflective responsiveness is clearly within the reach of many animals. We then defend that a key demonstration of reflective responsiveness would be the ability to respond to undermining defeaters. We end by presenting some empirical evidence that suggests that some animal species are capable of processing these defeaters, which would entail that even by the strictest standards, humans are not the only rational animals.

In this paper I argue that the debate between the so-called “presentists” – according to whom only the present is real – and the “eternalists”, according to whom past present and future are equally real, has no ontological significance. In particular, once we carefully distinguish between a tensed and a tenseless sense of existence, it is difficult to find a single ontological claim on which the two parties could disagree. Since the choice of using a tense or a tenseless language (...) is dictated by purely pragmatic reasons, we should abstain from bringing to bear pseudo-debates generated by the “tensed” or the “tenseless theories” of time on the question of understanding the philosophical implications of contemporary spacetime theories, or notions like becoming, change and persistence in time.

In this paper I examine the role of dispositional properties in the most frequently discussed interpretations of non-relativistic quantum mechanics. After offering some motivation for this project, I briefly characterize the distinction between non-dispositional and dispositional properties in the context of quantum mechanics by suggesting a necessary condition for dispositionality – namely contextuality – and, consequently, a sufficient condition for non-dispositionality, namely non-contextuality. Having made sure that the distinction is conceptually sound, I then analyze the plausibility of the widespread, monistic (...) ontological thesis about the reducibility of dispositional properties to categorical properties in the context of the philosophy of quantum mechanics. I conclude that with the exception of Bohmian mechanics, the other “minimally realist” views of quantum mechanics require essential dispositions, i.e., dispositions of a non-reducible kind. Interestingly, seen behind the lenses of dispositionalism, Bohr’s and Bohm’s interpretations of quantum mechanics are much closer than it is usually recognized, a fact that could teach us something about the way the quantum world is.

We investigate claims about the frequency of "know" made by philosophers. Our investigation has several overlapping aims. First, we aim to show what is required to confirm or disconfirm philosophers’ claims about the comparative frequency of different uses of philosophically interesting expressions. Second, we aim to show how using linguistic corpora as tools for investigating meaning is a productive methodology, in the sense that it yields discoveries about the use of language that philosophers would have overlooked if they remained in (...) their "armchairs of an afternoon", to use J.L. Austin’s phrase. Third, we discuss facts about the meaning of "know" that so far have been ignored in philosophy, with the aim of reorienting discussions of the relevance of ordinary language for philosophical theorizing.

Lawrence Kohlberg's Approach to Moral Education presents what the late Lawrence Kohlberg regarded as the definitive statement of his educational theory. Addressing the sociology and social psychology of schooling, the authors propose that school culture become the center of moral education and research. They discuss how schools can develop as just and cohesive communities by involving students in democracy, and they focus on the moral decisions teachers and students face as they democratically resolve problems. As the authors put it: "...we (...) propose an educational renewal of our democratic society.... We have attempted to establish schools that do more than just teach about democratic citizenship, that are themselves democratic societies.". (shrink)

The fictional worlds of science fiction can stimulate philosophical speculation towards socio-technical scenarios and trends that are extrapolated from our physical reality. This widely accepted observation highlights but one of the ways to pursue philosophy with the aid of fiction and science fiction in particular. In this paper, we argue that fiction can in itself constitute a philosophical, academic work and need not merely represent the subject about which such work speculates. This idea questions the currently predominant, institutional paradigm which (...) identifies philosophical works with written texts and specifically with a single kind of text: the paper-format (§1). To suggest an alternative way of doing philosophy, we analyse the structure and content of the recent, experimental science fiction book, The Clouds, and propose that its hybrid textuality – which leverages at once fiction, theory, and meta-commentary – offers a possible corrective to the cognitive closure and rigidity of expression encouraged by the institutionally accepted approach to philosophical work (§ 2).

I extend the Higher-Order View of Undermining Defeat (HOVUD) defended in Melis (2014) to account for the defeat of propositional justification. In doing so, I clarify the important notion of higher-order commitment, and I make some considerations concerning the defeat of externalist epistemic warrants.

This paper offers a critical assessment of the current state of the debate about the identity and individuality of material objects. Its main aim, in particular, is to show that, in a sense to be carefully specified, the opposition between the Leibnizian ‘reductionist’ tradition, based on discernibility, and the sort of ‘primitivism’ that denies that facts of identity and individuality must be analysable has become outdated. In particular, it is argued that—contrary to a widespread consensus—‘naturalised’ metaphysics supports both the acceptability (...) of non-qualitatively grounded (both ‘contextual’ and intrinsic) identity and a pluralistic approach to individuality and individuation. A case study is offered that focuses on non-relativistic quantum mechanics, in the context of which primitivism about identity and individuality, rather than being regarded as unscientific, is on the contrary suggested to be preferable to the complicated forms of reductionism that have recently been proposed. More generally, by assuming a plausible form of anti-reductionism about scientific theories and domains, it is claimed that science can be regarded as compatible with, or even as suggesting, the existence of a series of equally plausible grades of individuality. The kind of individuality that prevails in a certain context and at a given level can be ascertained only on the basis of the specific scientific theory at hand. (shrink)

After some suggestions about how to clarify the confused metaphysical distinctions between dispositional and non-dispositional or categorical properties, I review some of the main interpretations of QM in order to show that – with the relevant exception of Bohm’s minimalist interpretation – quantum ontology is irreducibly dispositional. Such an irreducible character of dispositions must be explained differently in different interpretations, but the reducibility of the contextual properties in the case of Bohmian mechanics is guaranteed by the fact that the positions (...) of particles play the role of the categorical basis, a role that in other interpretations cannot be filled by anything else. In Bohr’s and Everett-type interpretations, dispositionalism is instrumentalism in disguise. (shrink)

The use of the symbol ∨for disjunction in formal logic is ubiquitous. Where did it come from? The paper details the evolution of the symbol ∨ in its historical and logical context. Some sources say that disjunction in its use as connecting propositions or formulas was introduced by Peano; others suggest that it originated as an abbreviation of the Latin word for “or,” vel. We show that the origin of the symbol ∨ for disjunction can be traced to Whitehead and (...) Russell’s pre-Principia work in formal logic. Because of Principia’s influence, its notation was widely adopted by philosophers working in logic (the logical empiricists in the 1920s and 1930s, especially Carnap and early Quine). Hilbert’s adoption of ∨ in his Grundzüge der theoretischen Logik guaranteed its widespread use by mathematical logicians. The origins of other logical symbols are also discussed. (shrink)

In the first part of the paper I argue that an ontology of events is precise, flexible and general enough so as to cover the three main alternative formulations of quantum mechanics as well as theories advocating an antirealistic view of the wave function. Since these formulations advocate a primitive ontology of entities living in four-dimensional spacetime, they are good candidates to connect that quantum image with the manifest image of the world. However, to the extent that some form of (...) realism about the wave function is also necessary, one needs to endorse also the idea that the wave function refers to some kind of power. In the second part, I discuss some difficulties raised by the recent proposal that in Bohmian mechanics this power is holistically possessed by all the particles in the universe. (shrink)

In this paper I argue that even the most radical metaphysics of powers (such as that adopted by Mumford & Anjum, Cartwright, or Groff) are compatible with eternalism. I first offer a taxonomy of powers ontologies, and attempt to characterise the difference between moderate and radical powers ontologies – the latter are characterised by an emphasis on production and dynamicity. I consider an argument by C. Friebe to the effect that the productive character of powers is inconsistent with Eternalism and (...) find it wanting. I then elucidate the notion of dynamicity that radical powers theorists employ by making apparent their link with an ontology of irreducible processes. Finally, I respond to an argument by Donatella Donati to the effect that eternalism entails a reductive account of change which is inconsistent with process ontologies, and show that the the two are compatible. I conclude that we have no reason to think that radical powers metaphysics (and, a fortiori, every powers ontology) are not compatible with eternalism. (shrink)

Dispositionalism is the theory of modality according to which all (metaphysical and natural) modal truths are made true by some actual irreducibly dispositional property. The relationship between Dispositionalism and time is yet to be satisfactorily explored. In this paper we contribute to this task by examining how Dispositionalism deals with ‘dated truths’: propositions involving a specific time, e.g. “It might rain at 12.30”. We examine two possible accounts: the first, 'Dated Manifestations Strategy', is the idea that powers are very fine-grained, (...) and tend towards temporally very specific manifestations. We argue that such strategy should not be adopted, for it leads to unnecessary violations of ontological parsimony; it is unable to accommodate an ontology of platonic universals; and it is incapable of offering a principled explanation of the forward-looking nature of powers. We offer an alternative account, the "Duration Strategy", which relies on an independently determined arrow of time and the existence of some “duration facts” that specify how long a power takes to bring about its manifestation. We argue that the Duration Strategy is to be preferred. We then flesh out the account by exploring the connection between powers, duration facts, and processes. (shrink)

Establishing Dispositionalism as a viable theory of modality requires the successful fulfilment of two tasks: (i) showing that all modal truths can be derived from truths about actual powers, and (ii) offering a suitable metaphysics of powers. These two tasks are intertwined: difficulties in one can affect the chances of success in the other. In this paper, I generalise an objection to Dispositionalism by Jessica Leech and argue that the theory in its present form is ill-suited to account for de (...) re truths about merely possible entities. I argue that such difficulty is rooted in a problem in the metaphysics of powers. In particular, I contend that the well-known tension between two key principle of powers ontology, namely Directedness (all powers are “for” their manifestation) and Independence (some powers might fail to bring about their manifestation) has received an unsatisfactory solution so far, and that it is this unsatisfactory solution concerning the status of “unmanifested manifestations” that makes it hard for Dispositionalism to account for mere possibilia. I develop a novel account of the status of unmanifested manifestations and an overall metaphysics of powers which allows to better respond to Leech's objection and handle mere possibilia. The central idea of the proposal is that unmanifested manifestations are akin to mere logical existents, and are best characterised as non-essentially non-located entities. (shrink)

Vetter (2015) develops a localised theory of modality, based on potentialities of actual objects. Two factors play a key role in its appeal: its commitment to Hardcore Actualism, and to Naturalism. Vetter’s commitment to Naturalism is in part manifested in her adoption of Aristotelian universals. In this paper, we argue that a puzzle concerning the identity of unmanifested potentialities cannot be solved with an Aristotelian conception of properties. After introducing the puzzle, we examine Vetter’s attempt at amending the Aristotelian conception (...) in a way that avoids the puzzle, and conclude that this amended version is no longer to be considered naturalistic. Potentiality theory cannot be both actualist and naturalist. We then argue that, if naturalism is to be abandoned by the actualist, there are good reasons to adopt a Platonist conception of universals, for they offer a number of theoretical advantages and allow us to avoid some of the problems facing Vetter’s theory.

We focus on Timothy Williamson’s recent attack on the epistemological significance of the a priori–a posteriori distinction, and offer an explanation of why, fundamentally, it does not succeed. We begin by setting out Williamson’s core argument, and some of the background to it and move to consider two lines of conciliatory response to it—conciliatory in that neither questions the central analogy on which Williamson's argument depends. We claim, setting aside a methodological challenge to which Williamson owes an answer, that no (...) satisfactory such reconciliation is in prospect. Rather, as we then argue, —and it is on this that we base our overall negative assessment of his argument—Williamson’s core analogy is flawed by an oversight. We conclude with some brief reflections on Williamson’s ideas about the imagination as a source of knowledge. Our principal conclusion is only that Williamson’s argument fails to perform as advertised. A constructive case for confidence, to the contrary, that the intuitive contrast between a priori and a posteriori reflects something of fundamental epistemological significance is prefigured in our final section, but will not be elaborated here.

There is a tension between Dispositionalism––the view that all metaphysical modality is grounded in actual irreducible dispositional properties––and the possibility of time travel. This is due to the fact that Dispositionalism makes it much harder to solve a potentiality-based version of the grandfather paradox. We first present a potentiality-based version of the grandfather paradox, stating that the following theses are inconsistent: 1) time travel is possible, 2) powers fully ground modality, 3) self-defeating actions are impossible, 4) time-travellers retain their intrinsic (...) powers upon time-travelling, and 5) time-travellers are ordinary agents with basic intrinsic potentialities. We then consider a number of potential solutions, and find them wanting. We argue that the metaphysical impossibility of performing a self-defeating action acts as a necessary perfect mask––while time-travel lets us “slip” the potentiality under the mask, thus generating the contradiction. We conclude considering what are the options for the dispositionalist. (shrink)

This paper -distinguishes between the Hypothesis of Extended Cognition and the Hypothesis of Embedded Cognition, characterizing them as competitors (both motivated by situated, interactive cognitive processing, with the latter being the more conservative of the two interpretations of the data) -clarifies the relation between content externalism and extended cognition -introduces the problem of cognitive bloat, as part of a critical discussion of Clark and Chalmers's "past-endorsement criterion" (if the criterion is embraced, we privilege the internal, endorsing process -- which looks (...) more like an embedded view -- and if the criterion is rejected, bloat follows) and as a problem for extended views more generally -develops a dilemma critical of Clark and Chalmers's "explanatory kinds" argument for extended mind and cognition (arguing that their reasoning faces serious problems regardless of whether one individuates the kinds in question in a fine-grained or a coarse-grained way) -argues that an appeal to functionalism doesn't resolve the issue -argues for the priority, in debates about extended cognition, of the identification of cognitive systems (e.g., because a functionalist approach can't be applied unless we already know what count as inputs and outputs, which requires having already identified the boundaries of the cognitive system).

Many philosophers are impressed by the progress achieved by physical sciences. This has had an especially deep effect on their ontological views: it has made many of them physicalists. Physicalists believe that everything is physical: more precisely, that all entities, properties, relations, and facts are those which are studied by physics or other physical sciences. They may not all agree with the spirit of Rutherford's quoted remark that 'there is physics; and there is stamp-collecting',' but they all grant physical science (...) a unique ontological authority: the authority to tell us what there is. Physicalism is now almost orthodox in much philosophy, notably in much recent philosophy of mind. But although often invoked, it is rarely explicitly defined. It should be. The claim that everything is physical is not as clear as it seems. In this paper, we examine a number of proposed definitions of physicalism and reasons for being a physicalist. We will argue both that physicalism lacks a clear and credible definition, and that in no non-vacuous interpretation is it true. We are concerned here only with physicalism as a doctrine about the empirical world. In particular, it should not be confused with nominalism, the doctrine that there are no universals.2 Nominalism and physicalism are quite independent doctrines. Believers in universals may as consistently assert as deny that the only properties and relations are those studied by physical science. And nominalists may with equal consistency assert or deny that physical science could provide enough predicates to describe the world. That is the question which concerns physicalists, not whether physical predicates name real universals. (We will for brevity write as if they do, but we do not need that assumption.). (shrink)

An influential position in the philosophy of biology claims that there are no biological laws, since any apparently biological generalization is either too accidental, fact-like or contingent to be named a law, or is simply reducible to physical laws that regulate electrical and chemical interactions taking place between merely physical systems. In the following I will stress a neglected aspect of the debate that emerges directly from the growing importance of mathematical models of biological phenomena. My main aim is to (...) defend, as well as reinforce, the view that there are indeed laws also in biology, and that their difference in stability, contingency or resilience with respect to physical laws is one of degrees, and not of kind .

Kriegel described the problem of intentional inexistence as one of the ‘perennial problems of philosophy’, 307–340, 2007: 307). In the same paper, Kriegel alluded to a modal realist solution to the problem of intentional inexistence. However, Kriegel does not state by name who defends the kind of modal realist solution he has in mind. Kriegel also points out that even what he believes to be the strongest version of modal realism does not pass the ‘principle of representation’ and thus modal (...) realism is not an adequate solution to the problem of intentional inexistence. In this paper, I respond to Kriegel by defending a modal realist solution that he did not consider in 2007, called ‘extended modal realism’. EMR is a version of modal realism where possible worlds are not completely isolated as they are under the Lewisian model. Rather, under EMR worlds are, in a way, spatiotemporally related. The fact EMR worlds are related allows EMR to sufficiently pass the principle of representation and thus can be deemed a legitimate solution to the problem of intentional inexistence. I conclude that either EMR can pass the principle of representation in some cases or, and I think the more sensible option, we give up on the principle of representation altogether. (shrink)

One emerging issue in contemporary epistemology concerns the relation between animal knowledge, which can be had by agents unable to take a view on the epistemic status of their attitudes, and reflective knowledge, which is only available to agents capable of taking such a view. Philosophers who are open to animal knowledge often presume that while many of the beliefs of human adults are formed unreflectively and thus constitute mere animal knowledge, some of them—those which become subject of explicit scrutiny (...) or are the result of a deliberative effort—may attain the status of reflective knowledge. According to Sanford Goldberg and Jonathan Matheson (2020), however, it is impossible for reflective subjects to have mere animal knowledge. If correct, their view would have a number of repercussions, perhaps most notably the vindication of a dualism about knowledge, which would frustrate attempts to provide a unified account of knowledge-attributions to human adults, very young children, and non-human animals. I discuss Goldberg and Matheson’s proposal, outline some of the ways in which it is insightful, and argue that it is ultimately unsuccessful because it neglects the inherent temporal dimension of knowledge acquisition. While the article is pitched as a reply to Goldberg and Matheson, its primary aim is to highlight significant connections between the debates on the relation between animal and reflective knowledge, propositional and doxastic justification, and the theory of epistemic defeat.

In this paper I review three different positions on the wave function, namely: nomological realism, dispositionalism, and configuration space realism by regarding as essential their capacity to account for the world of our experience. I conclude that the first two positions are committed to regard the wave function as an abstract entity. The third position will be shown to be a merely speculative attempt to derive a primitive ontology from a reified mathematical space. Without entering any discussion about nominalism, I (...) conclude that an elimination of abstract entities from one’s ontology commits one to instrumentalism about the wave function, a position that therefore is not as unmotivated as it has seemed to be to many philosophers.

John McDowell articulated a radical criticism of normative inferentialism against Robert Brandom’s expressivist account of conceptual contents. One of his main concerns consists in vindicating a notion of intentionality that could not be reduced to the deontic relations that are established by discursive practitioners. Noticeably, large part of this discussion is focused on empirical knowledge and observational judgments. McDowell argues that there is no role for inference in the application of observational concepts, except the paradoxical one of justifying the content (...) of an observational judgment in terms of itself. This paper examines the semantical consequences of the analysis of the content of empirical judgments in terms of their inferential role. These, it is suggested, are distinct from the epistemological paradoxes that McDowell charges the inferentialist approach with. (shrink)

Interactive theorem provers might seem particularly impractical in the history of philosophy. Journal articles in this discipline are generally not formalized. Interactive theorem provers involve a learning curve for which the payoffs might seem minimal. In this article I argue that interactive theorem provers have already demonstrated their potential as a useful tool for historians of philosophy; I do this by highlighting examples of work where this has already been done. Further, I argue that interactive theorem provers can continue to (...) be useful tools for historians of philosophy in the future; this claim is defended through a more conceptual analysis of what historians of philosophy do that identifies argument reconstruction as a core activity of such practitioners. It is then shown that interactive theorem provers can assist in this core practice by a description of what interactive theorem provers are and can do. If this is right, then computer verification for historians of philosophy is in the offing. (shrink)

Since the onset of logical positivism, the general wisdom of the philosophy of science has it that the kantian philosophy of (space and) time has been superseded by the theory of relativity, in the same sense in which the latter has replaced Newton’s theory of absolute space and time. On the wake of Cassirer and Gödel, in this paper I raise doubts on this commonplace by suggesting some conditions that are necessary to defend the ideality of time in the sense (...) of Kant. In the last part of the paper I bring to bear some contemporary physical theories on such conditions. (shrink)

In this paper I present and critically discuss the main strategies that Bohr used and could have used to fend off the charge that his interpretation does not provide a clear-cut distinction between the classical and the quantum domain. In particular, in the first part of the paper I reassess the main arguments used by Bohr to advocate the indispensability of a classical framework to refer to quantum phenomena. In this respect, by using a distinction coming from an apparently unrelated (...) philosophical corner, we could say that Bohr is not a revisionist philosopher of physics but rather a descriptivist one in the sense of Strawson. I will then go on discussing the nature of the holistic link between classical measurement apparatuses and observed system that he also advocated. The oft-repeated conclusion that Bohr’s interpretation of the quantum formalism is untenable can only be established by giving his arguments as much force as possible, which is what I will try to do in the following by remaining as faithful as possible to his published work.

This essay gives an account of epistemic deference for agents with imprecise credences. I look at the two main imprecise deference principles in the literature, known as Identity Reflection and Pointwise Reflection (Moss, 2021). I show that Pointwise Reflection is strictly weaker than Identity Reflection, and argue that, if you are certain you will update by conditionalisation, you should defer to your future self according to Identity Reflection. Then I give a more general justification for Pointwise and Identity Reflection from (...) the assumption that you defer to someone whenever you consider their doxastic state to be better than yours, in the sense of leading to better decision-making.

The main claim that I want to defend in this paper is that the there are logical equivalences between eternalism and perdurantism on the one hand and presentism and endurantism on the other. By “logical equivalence” I mean that one position is entailed and entails the other. As a consequence of this equivalence, it becomes important to inquire into the question whether the dispute between endurantists and perdurantists is authentic, given that Savitt (2006) Dolev (2006) and Dorato (2006) have cast (...) doubts on the fact that the debate between presentism and eternalism is about “what there is”. In this respect, I will conclude that also the debate about persistence in time has no ontological consequences, in the sense that there is no real ontological disagreement between the two allegedly opposite positions: as in the case of the presentism/eternalism debate, one can be both a perdurantist and an endurantist, depending on which linguistic framework is preferred.

Efforts to bridge emotion theory with neurobiology can be facilitated by dynamic systems (DS) modeling. DS principles stipulate higher-order wholes emerging from lower-order constituents through bidirectional causal processes cognition relations. I then present a psychological model based on this reconceptualization, identifying trigger, self-amplification, and self-stabilization phases of emotion-appraisal states, leading to consolidating traits. The article goes on to describe neural structures and functions involved in appraisal and emotion, as well as DS mechanisms of integration by which they interact. These mechanisms (...) include nested feedback interactions, global effects of neuromodulation, vertical integration, action-monitoring, and synaptic plasticity, and they are modeled in terms of both functional integration and temporal synchronization. I end by elaborating the psychological model of emotion–appraisal states with reference to neural processes. (shrink)

In this paper, we review and connect the three essential conditions needed by the collapse model to achieve a complete and exact formulation, namely the theoretical, the experimental, and the ontological ones. These features correspond to the three parts of the paper. In any empirical science, the first two features are obviously connected but, as is well known, among the different formulations and interpretations of non-relativistic quantum mechanics, only collapse models, as the paper well illustrates with a richness of details, (...) have experimental consequences. Finally, we show that a clarification of the ontological intimations of collapse models is needed for at least three reasons: (1) to respond to the indispensable task of answering the question ’what are collapse models (and in general any physical theory) about?’; (2) to achieve a deeper understanding of their different formulations; (3) to enlarge the panorama of possible readings of a theory, which historically has often played a fundamental heuristic role.

The no-miracles argument and the pessimistic induction are arguably the main considerations for and against scientific realism. Recently these arguments have been accused of embodying a familiar, seductive fallacy. In each case, we are tricked by a base rate fallacy, one much-discussed in the psychological literature. In this paper we consider this accusation and use it as an explanation for why the two most prominent `wholesale' arguments in the literature seem irresolvable. Framed probabilistically, we can see very clearly why realists (...) and anti-realists have been talking past one another. We then formulate a dilemma for advocates of either argument, answer potential objections to our criticism, discuss what remains (if anything) of these two major arguments, and then speculate about a future philosophy of science freed from these two arguments. In so doing, we connect the point about base rates to the wholesale/retail distinction; we believe it hints at an answer of how to distinguish profitable from unprofitable realism debates. In short, we offer a probabilistic analysis of the feeling of ennui afflicting contemporary philosophy of science. (shrink)

The article reassesses Schelling’s philosophy of art in the System of Transcendental Idealism, focusing on its practical philosophy and the concept of the artefact. Often unexplored, this perspective offers a new account of Schelling’s early aesthetics, linking aesthetic experience to historical becoming. The discussion begins with an analysis of Schelling’s theory of intentional action, followed by a reconstruction of his understanding of artefact. It argues that Schelling integrates both social and material dimensions into his concept of artefacts. The paper then (...) examines Schelling’s comparison between artefacts in general and works of art, asserting that aesthetic experience in the context of the System exemplifies ‘hermeneutic obstinacy’. This characteristic, typical of works of art, correlates with the open nature of historical reality. (shrink)

“Love hurts”—as the saying goes—and a certain amount of pain and difficulty in intimate relationships is unavoidable. Sometimes it may even be beneficial, since adversity can lead to personal growth, self-discovery, and a range of other components of a life well-lived. But other times, love can be downright dangerous. It may bind a spouse to her domestic abuser, draw an unscrupulous adult toward sexual involvement with a child, put someone under the insidious spell of a cult leader, and even inspire (...) jealousy-fueled homicide. How might these perilous devotions be diminished? The ancients thought that treatments such as phlebotomy, exercise, or bloodletting could “cure” an individual of love. But modern neuroscience and emerging developments in psychopharmacology open up a range of possible interventions that might actually work. These developments raise profound moral questions about the potential uses—and misuses—of such anti-love biotechnology. In this article, we describe a number of prospective love-diminishing interventions, and offer a preliminary ethical framework for dealing with them responsibly should they arise. (shrink)

In his 1918 logical atomism lectures, Russell argued that there are no molecular facts. But he posed a problem for anyone wanting to avoid molecular facts: we need truth-makers for generalizations of molecular formulas, but such truth-makers seem to be both unavoidable and to have an abominably molecular character. Call this the problem of generalized molecular formulas. I clarify the problem here by distinguishing two kinds of generalized molecular formula: incompletely generalized molecular formulas and completely generalized molecular formulas. I next (...) argue that, if empty worlds are logically possible, then the model-theoretic and truth-functional considerations that are usually given address the problem posed by the first kind of formula, but not the problem posed by the second kind. I then show that Russell’s commitments in 1918 provide an answer to the problem of completely generalized molecular formulas: some truth-makers will be non-atomic facts that have no constituents. This shows that the neo-logical atomist goal of defending the principle of atomicity—the principle that only atomic facts are truth-makers—is not realizable. (shrink)

Scientific realists have claimed that the posit that our theories are (approximately) true provides the best or the only explanation for their success . In response, I revive two non-realists explanations. I show that realists, in discarding them, have either misconstrued the phenomena to be explained or mischaracterized the relationship between these explanations and their own. I contend nonetheless that these non-realist competitors, as well as their realist counterparts, should be rejected; for none of them succeed in explaining a significant (...) list of successes. I propose a related non-realist explanation of success that appears to be the most suitable among those considered. (shrink)

This article presents the incidence of the symbol through Latin-American philosophical reflection.

The incidence of the symbol in the educational process is performed through an ethical perspective and hermeneutics that focuses on new alternatives for teaching (...) philosophy in the classroom.

In my review of Steven French's The structure of the world. Metaphysics & Representation. OUP, Oxford, 2014 I argue that the author is forced to navigate between the Scilla of Tegmark’s Pitagoreanism (2008) and the Carybdis of “blobobjectivism” (Horgan and Potrč 2008), namely the claim that the whole physical universe is a single concrete structurally complex but partless cosmos (a “blob”).

This paper generalises an argument for probabilism due to Lindley [9]. I extend the argument to a number of non-classical logical settings whose truth-values, seen here as ideal aims for belief, are in the set $\{0,1\}$, and where logical consequence $\models $ is given the “no-drop” characterization. First I will show that, in each of these settings, an agent’s credence can only avoid accuracy-domination if its canonical transform is a (possibly non-classical) probability function. In other words, if an agent values (...) accuracy as the fundamental epistemic virtue, it is a necessary requirement for rationality that her credence have some probabilistic structure. Then I show that for a certain class of reasonable measures of inaccuracy, having such a probabilistic structure is sufficient to avoid accuracy-domination in these non-classical settings. (shrink)

By briefly reviewing three well-known scientific revolutions in fundamental physics (the discovery of inertia, of special relativity and of general relativity), I claim that problems that were supposed to be crying for a dynamical explanation in the old paradigm ended up receiving a structural explanation in the new one. This claim is meant to give more substance to Kuhn’s view that revolutions are accompanied by a shift in what needs to be explained, while suggesting at the same time the existence (...) of a pattern that is common to all of the discussed case-studies. It remains to be seen whether also quantum mechanics, in particular entanglement, conforms to this pattern. (shrink)

A new translation and edition of Aristotle's Protrepticus (with critical comments on the fragments) -/- Welcome -/- The Protrepticus was an early work of Aristotle, written while he was still a member of Plato's Academy, but it soon became one of the most famous works in the whole history of philosophy. Unfortunately it was not directly copied in the middle ages and so did not survive in its own manuscript tradition. But substantial fragments of it have been preserved in several (...) works by Iamblichus of Chalcis, a third century A.D. neo-Pythagorean philosopher and educator. On the basis of a close study of Iamblichus' extensive use and excerption of Aristotle's Protrepticus, it is possible to reconstruct the backbone of the lost work, and then to flesh it out with the other surviving reports about the work from antiquity (for example in Alexander of Aphrodisias and other ancient commentators on Aristotle). It is also possible to identify several papyrus fragments of the work, and many references and literary allusions in later authors, especially Cicero, whose own lost dialogue Hortensius was a defense of philosophy modeleld on Aristotle's.

The main claim of the paper is that one can be ‘realist’ (in some sense) about quantum mechanics without requiring any form of realism about the wave function. We begin by discussing various forms of realism about the wave function, namely Albert’s configuration-space realism, Dürr Zanghi and Goldstein’s nomological realism about Ψ, Esfeld’s dispositional reading of Ψ Pusey Barrett and Rudolph’s realism about the quantum state. By discussing the articulation of these four positions, and their interrelation, we conclude that instrumentalism (...) about Ψ is by itself not sufficient to choose one over the other interpretations of quantum mechanics, thereby confirming in a different way the indetermination of the metaphysical interpretations of quantum mechanics. -/- Key words: .
