The mask's role is central to the superhero narrative. The mask is a non-human identity, which replaces the civilian, human one; sometimes forever. It is what happens to the majority of Gotham's villains. While Batman can take off his mask and at least pretend to be Bruce Wayne, many of his enemies do not have the same privilege. For characters like Two-Face, Joker, Zsasz, and Clayface, the mask is carved directly into their bodies. Like masks, scars can replace one's identity, (...) but deeply and sometimes irreversibly. Bodies and masks play a central role in ancient primitive cultures, especially during initiation rituals. The two elements are distinct, but closely linked. Wearing a mask always implies a modification of the body, or at least of the way it is perceived. Furthermore, marks left on the body, whether temporary like a face paint or definitive like a tattoo, perform a similar function to that of the mask: they replace the individual's identity and communicate a message. The initiation ceremonies destroy a previous identity to create a new one. While an individuum is a Leib, a living body that is becoming and escapes an ultimate meaning, by inflicting pain and scars, the initiation rituals aim to reduce the body to a stable dimension. First an ecstasy, induced by drugs and fasting, and through the infliction of physical pain, shatters the previous identity. The Leib is reduced to the passivity of flesh. Then a new identity is literally written on the body through scars or tattoos, thus receiving an "ultimate" sense and giving him/her a role and a place within society. The scar is a new identity, like a mask carved directly on the body. (shrink)

Dylan Dog, l’Indagatore dell’Incubo (the nightmare investigator), lives and works at 7 Craven Road in London. The comic book character is English, but he was created in Italy by Tiziano Sclavi in 1986, and it is still published today monthly. Dylan had enormous success, not only in Italy but worldwide. His job is to investigate, together with his assistant, Groucho, the paranormal, the irrational, the nightmare that can assume different forms and aspects. Dylan fights against all types of monsters: vampires, (...) zombies, werewolves, witches, even against Death itself. However, the horror that he faces is not always paranormal. The monsters are often extremely human. Maybe that is the reason why Dylan remains extremely skeptical and rational. Everything in Dylan Dog’s world revolves around the absurd, the chaos without explanation, without sense, and the need to find meaning in it. This chaos can take different forms: the horror that Dylan fights, but also the satirical and nonsense humor of Groucho. This irrational dimension manifests itself also through Dylan’s love and sexual life: in almost every story, Dylan falls in love with a different woman, who usually will die or will break his heart. Love and sex are strongly connected with horror and death in Dylan Dog’s narrative: they are irrational forces, from which it is not possible to escape. The purpose of this essay is to analyze the irrational and fearful dimension in Dylan Dog: l’orrore, as he calls it, but also its connection to sexuality and the comic relief provided by Groucho. This chaotic and monstrous reality will be analyzed mainly—but not only—through the Nietzschean concepts of Apollonian and Dionysian related to the concept of absurd as described by Albert Camus. In this frame, the analysis of René Girard’s Violence and the Sacred will also be helpful. Violence is an irrational and uncontrollable force, and its manifestation is tightly linked with the horror and the monstrous reality that it unveils. (shrink)

Cartesian and Western religious and philosophical traditions distinguish the body from the mind, viewing the former as a prison or a burden. The mind (spirit, soul, rationality) is identified as good, while the body is devalued and associated with evil. Some philosophers restored the body's value: humans are not imprisoned spirits, but they are their bodies. Husserl, for example, claims that human beings are not an immaterial substance in a Körper, a physical body, but Leib, a living body that solves (...) within itself the two Cartesian res. Although the Cartesian legacy survives in the Existentialism in the distinction between In-itself (the passive Being) and For-itself (the human, transcendental freedom), the second does not use the object-body as the res cogitans did: "the very nature of the For-itself demands that it be body." Nevertheless, the body plays an ambivalent role, suspended between Körper's passivity and Leib's transcendence. The chapter's focus on Arkham's female characters is not random. Leder notices that "women have consistently been associated with the bodily sphere. They have been linked with nature, sexuality, and the passions, whereas men have been identified with the rational mind. This equation implicitly legitimizes structures of domination." By associating human categories like "lunatics," "savages," or women with the immanence of the body and nature, their transcendentality is denied, and, simultaneously, men's control and domination over them is justified.

While much of the scholarship on superhero narratives has focused on the heroes themselves, Batman’s Villains and Villainesses: Multidisciplinary Perspectives on Arkham’s Souls takes into view the depiction of the villains and their lives, arguing that they often function as proxies for larger societal and philosophical themes. Approaching Gotham’s villains from a number of disciplinary backgrounds, the essays in this collection highlight how the villains’ multifaceted backgrounds, experiences, motivations, and behaviors allow for in-depth character analysis across varying levels of social (...) life. Through investigating their cultural and scholarly relevance across the humanities and social sciences, the volume encourages both thoughtful reflection on the relationship between individuals and their social contexts and the use of villains (inside and outside of Gotham) as subjects of pedagogical and scholarly inquiry.

Since the publication of Kitcher’s influential paper The Division of Cognitive Labor, some philosophers wondered about these two related issues: (1) which is the optimal distribution of cognitive efforts among rival methods within a scientific community?, and (2) whether and how can a community achieve such an optimal distribution? Though not committing to any specific answer to question (1), I claim that issue (2) does not depend exclusively on an invisible hand like mechanism, since both intra-scientific and extra-scientific institutions may (...) play a major role. Finally, I examine some practical difficulties of reallocating scientists from a method to another, which leads to stress the importance of well-planned training and recruitment. (shrink)

"Patterns of psychoanalysis and theory of recognition. Axel Honneth’s intersubjective psyche". An overview of the several scopes and patterns used over time by Axel Honneth in his “theory of recognition” is presented. After a discussion of the use of object relations theory (especially with reference to D.W. Winnicott’s contributions) in Honneth’s 1992 book Struggle for Recognition, the theoretical revision of psychoanalysis in light of his theory of recognition is examined. Finally, Honneth’s suggestion of a new alliance between a renewed “critical (...) theory” and psychoanalysis, which concerns also the dimension of political psychology, is discussed. -/- Viene offerta una panoramica sui differenti usi e le diverse forme di psicoanalisi utilizzate da Axel Honneth in relazione alla sua “teoria del riconoscimento” nel corso del tempo. Dopo una discussione dell’uso della teoria delle relazioni oggettuali (soprattutto nella concezione di D.W. Winnicott) in Lotta per il riconoscimento, del 1992, si prende in esame la revisione della psicoanalisi operata in termini di teoria del riconoscimento. Infine viene discussa la proposta di una nuova alleanza tra una “teoria critica” rinnovata e la psicoanalisi, che contempla anche il versante della psicologia politica. (shrink)

Higher-order evidence appears to have the ability to defeat rational belief. It is not obvious, however, why exactly the defeat happens. In this paper, I consider two competing explanations of higher-order defeat: the “Objective Higher-Order Defeat Explanation” and the “Subjective Higher-Order Defat Explanation.” According to the former explanation, possessing sufficiently strong higher-order evidence to indicate that one’s belief about p fails to be rational is necessary and sufficient for defeating one’s belief about p. I argue that this type of explanation (...) is defective or at best collapses into the other type of explanation. According to the latter explanation, Believing that one’s belief about p fails to be rational (in response to higher-order evidence about p) is necessary and sufficient for defeating one’s belief about p. I argue that this type of explanation is better suited to explain higher-order defeat given that what one is rational to believe partly depends on the relations among one’s doxastic attitudes. Finally, I address an peculiar feature of the Subjective Higher-Order Defeat Explanation: higher-order defeat becomes contingent on one’s response to the higher-order evidence. (shrink)

Husserl’s phenomenology of imagination embraces a cluster of different theories and approaches regarding the multi-faced phenomenon of imaginative experience. In this paper I consider one aspect that seems to be crucial to the understanding of a particular form of imagination that Husserl names pure phantasy. I argue that the phenomenon of Ego-splitting discloses the best way to elucidate the peculiarity of pure phantasy with respect to other forms of representative acts and to any simple form of act modification. First, I (...) unravel the phenomenological distinctions which, respectively, oppose phantasy to perception, on the one hand, and phantasy to other forms of the so-called “intuitive re-presentations”. Second, I introduce the difference between presentative and representative acts, arguing that this cannot help us to single out the defining feature of phantasy experiences. The third section draws again an important distinction between pure phantasy and neutrality modification, which allows me to finally determine an internal trait of phantasy experiences, which Husserl refers to as the “Ego-splitting”. In this way, I hope to contribute to a refined characterization of Husserl’s phenomenology of imagination. (shrink)

According to some critics, Aristotle’s elenctic defence (elenchos, elenchus) of the Law of Non-Contradiction (Metaphysics IV) would be ineffective because it viciously begs the question. After briefly recalling the elenctic refutation of the denier of the Law of Non-Contradiction, I will first focus on Filippo Costantini’s objection to the elenchus, which, in turn, is based on the dialetheic account of negation developed by Graham Priest. Then, I will argue that there is at least one reading of the elenchus that might (...) not be viciously question-begging. In doing so, I will leverage, reinterpret and adjust the distinction between two senses of epistemic dependence, offered by Noah Lemos and originally based on some thoughts about George Edward Moore’s ‘proof of an external world.’ The key point of my counter-objection to recover the elenchus is to use the distinction between a necessary-condition relation between propositions (p only if q) and a grounding relation between facts (the fact that an epistemic agent S believes that p is grounded in the fact that S believes that q), where p and q are the content of S’s beliefs.

Reduzindo a fonte dos conhecimentos aos dados sensíveis, o empirismo pode ser concebido basicamente de dois modos: a partir da aquisição dos conteúdos do pensamento, ou a partir da constituição empírica da própria subjetividade. A segunda hipótese, em suas linhas gerais, foi apresentada explicitamente por G. Deleuze. Este texto, ao examinar esta segunda hipótese, restringe-se a uma análise exaustiva da memória e da imaginação, procurando expor os passos pelos quais Hume constitui distintos modos de operar da mente humana em conformidade (...) com os pressupostos radicais do que denominou filosofia experimental.

In this paper I challenge the pernicious aspects of Milton Friedman's methodological outlook that continues to hold sway over mainstream neoclassical economists. I do this by showing how Friedman's own methodological dicta could have been used against him when he famously advanced the expectations critique of the Phillips curve at his presidential address to the American Economic Association. I use this case study to further suggest that psychological and neurophysiological data should not be deemed irrelevant to economic science.

AI-based technologies are increasingly pervasive in a number of contexts. Our affective and emotional life makes no exception. In this article, we analyze one way in which AI-based technologies can affect them. In particular, our investigation will focus on affective artificial agents, namely AI-powered software or robotic agents designed to interact with us in affectively salient ways. We build upon the existing literature on affective artifacts with the aim of providing an original analysis of affective artificial agents and their distinctive (...) features. We argue that, unlike comparatively low-tech affective artifacts, affective artificial agents display a specific form of agency, which prevents them from being perceived by their users as extensions of their selves. In addition to this, we claim that their functioning crucially depends on the simulation of human-like emotion-driven behavior and requires a distinctive form of transparency—we call it emotional transparency—that might give rise to ethical and normative tensions.

Across two studies, one of which was pre-registered, we find that a simple questionnaire that measures intellectual virtue and vice predicts how many fake news articles and conspiracy theories participants accept. This effect holds even when controlling for multiple demographic predictors, including age, household income, sex, education, ethnicity, political affiliation, religion, and news consumption. These results indicate that self-report is an adequate way to measure intellectual virtue and vice, which suggests that they are not fully immune to introspective awareness or (...) “stealthy” in the sense that Cassam (2015) argues. This is an important methodological result and may pave the way for future research on intellectual virtue and vice. (shrink)

Some philosophers search for the mark of the cognitive: a set of individually necessary and jointly sufficient conditions identifying all instances of cognition. They claim that the mark of the cognitive is needed to steer the development of cognitive science on the right path. Here, I argue that, at least at present, it cannot be provided. First (§2), I identify some of the factors motivating the search for a mark of the cognitive, each yielding a desideratum the mark is supposed (...) to satisfy (§2.1). I then (§2.2) highlight a number of tensions in the literature on the mark of the cognitive, suggesting they’re best resolved by distinguishing two distinct programs. The first program (§3) is that of identifying a mark of the cognitive capturing our everyday notion of cognition. I argue that such a program is bound to fail for a number of reasons: it is not clear whether such an everyday notion exists; and even if it existed, it would not be able to spell out individually necessary and jointly sufficient conditions for cognition; and even if it were able to spell them out, these conditions won’t satisfy the desiderata a mark of the cognitive should satisfy. The second program is that of identifying a mark of the cognitive spelling out a genuine scientific kind. But the current state of fragmentation of cognitive science, and the fact that it is splintered in a myriad of different research traditions, prevent us from identifying such a kind. And we have no reason to think that these various research traditions will converge, allowing us to identify a single mark. Or so, at least, I will argue in (§4). I then conclude the paper (§5) deflecting an intuitive objection, and exploring some of the consequences of the thesis I have defended. (shrink)

Structural representations are increasingly popular in philosophy of cognitive science. A key virtue they seemingly boast is that of meeting Ramsey's job description challenge. For this reason, structural representations appear tailored to play a clear representational role within cognitive architectures. Here, however, I claim that structural representations do not meet the job description challenge. This is because even our most demanding account of their functional profile is satisfied by at least some receptors, which paradigmatically fail the job description challenge. Hence, (...) the functional profile typically associated with structural representations does not identify representational posits. After a brief introduction, I present, in the second section of the paper, the job description challenge. I clarify why receptors fail to meet it and highlight why, as a result, they should not be considered representations. In the third section I introduce what I take to be the most demanding account of structural representations at our disposal, namely Gładziejewski's account. Provided the necessary background, I turn from exposition to criticism. In the first half of the fourth section, I equate the functional profile of structural representations and receptors. To do so, I show that some receptors boast, as a matter of fact, all the functional features associated with structural representations. Since receptors function merely as causal mediators, I conclude structural representations are mere causal mediators too. In the second half of the fourth section I make this conclusion intuitive with a toy example. I then conclude the paper, anticipating some objections my argument invites. (shrink)

The perpetual secretary of the Berlin Academy Johann Heinrich Samuel Formey is best known as a populariser of Christian Wolff’s doctrines. As of Formey’s activity in the Berlin Academy, scholars have mostly emphasized his role in the controversy over monads with Leonhard Euler, while overlooking other interesting contributions Formey presented in the “speculative philosophy” class of the Academy. In this paper, I analyse two articles Formey published in 1747 on the Mémoires de l’Académie de Berlin, namely the Preuves de l’existence (...) de Dieu, ramenées aux notions communes and the Examen de la preuve qu’on tire des fins de la nature, pour établir l’existence de Dieu. In these texts, Formey presents some of Wolff’s methodological and metaphysical ideas, in an implicit dialogue with other members of the Academy – in particular, with the president Pierre-Louis Moreau de Maupertuis – who were also interested in metaphysics and the philosophical method. Formey reworks the Wolffian arguments as to make them more accessible, in order to promote an open confrontation over core philosophical questions. Far from adopting a controversial tone, Formey’s attitude is rather conciliatory: any disagreement, as he thinks, can be easily settled once the true method for philosophizing is made available to everybody.

I discuss Clark’s predictive processing/extended mind hybrid, diagnosing a problem: Clark’s hybrid suggests that, when we use them, we pay attention to mind-extending external resources. This clashes with a commonly accepted necessary condition of cognitive extension; namely, that mind-extending resources must be phenomenally transparent when used. I then propose a solution to this problem claiming that the phenomenal transparency condition should be rejected. To do so, I put forth a parity argument to the effect that phenomenal transparency cannot be a (...) necessary condition on cognitive extension: roughly, since internal cognitive resources can fail to be transparent when used, by parity, external resources can fail to be phenomenally transparent too. Further, I argue that phenomenal transparency is not even a reliable indicator of cognitive extension; hence its absence should not be considered a problem for Clark’s extended mind-predictive processing hybrid. Lastly, I consider and allay a number of worries my proposal might raise, and conclude the paper. (shrink)

In this paper we assess two sides of the debate concerning biomedical enhancement. First, the idea that biomedical enhancement should be prohibited on the grounds that it degrades human nature; second, that biomedical enhancement can in principle remove the source of moral evil. In so doing, we will propose a different notion of human nature, what we shall call the agato-teleological idea of human nature, and its implications for a philosophical understanding of the human body. Also, we will point out (...) why it seems unreasonable to think that bodily enhancement is sufficient to guarantee moral progress. Finally, we will propose the idea that our technological societies are in need of a new moral virtue, what we shall call the virtue of non-conservative bodily integrity. (shrink)

According to the extended cognition thesis, an agent’s cognitive system can sometimes include extracerebral components amongst its physical constituents. Here, we show that such a view of cognition has an unjustifiably anthropocentric focus, for it tends to depict cognitive extensions as a human-only affair. In contrast, we will argue that if human cognition extends, then the cognition of many non-human animals extends too, for many non-human animals rely on the same cognition-extending strategies humans rely on. To substantiate this claim, we (...) will proceed as follows. First (Sect. 1), we will introduce the extended cognition thesis, exposing its anthropocentric bias. Then, we will show that humans and many non-human animals rely on the same cognition-extending strategies. To do so, we will discuss a variety of case studies, including “intrabodily” cognitive extensions such as the spinal cord (Sect. 2), the widespread reliance on epistemic actions to solve cognitive tasks (Sect. 3) and cases of animal cognitive offloading (Sect. 4). We’ll then allay some worries our claim might raise (Sect. 5) to then conclude the paper (Sect. 6). (shrink)

This paper focuses on Schopenhauer’s On the Will in Nature (1836), a book which is generally underestimated by scholars interested in Schopenhauer’sphilosophy. This essay analyses its genesis in Schopenhauer’s manuscripts, examines its role in Schopenhauer’s thought and its relationship with The World asWill and Representation, and locates its content and meaning with reference to the philosophical and scientific context. Aim of the article is a better understanding of Schopenhauer’s treatise, and such a scope is pursued by accurate insight of its (...) central theme: the notion of Bestätigung, that is the scientific corroboration of the philosophical knowledge.

The aim of this article is to address the problem of what is usually called “self-consciousness” by studying Charles S. Peirce’s semeiotic treatment of self-referential statements. Peirce believes that an adequate study of the mind requires “to reduce all mental action,” including “self-consciousness,” “to the formula of valid reasoning” (W 2:214, EP 1:30, 5:267, 1868) and its semeiotic nature. While Peirce makes frequent use of the notion of “consciousness,” he is at the same time distant from the understanding of the (...) “conscious mind” that Descartes invented and made canonical (e.g., W 1:491, 1866), and which from the modern epoch stretches out to the contemporary discussion on, as David Chalmers put it, the “hard problem” of the mind. In what follows, I argue that Peirce puts forth a powerful theory of self-consciousness based on his semeiotic understanding of self-reference and indexicality. To the question, “How can we elucidate the phenomenon of self-consciousness?”, we should answer, with Peirce, “What we call self-consciousness corresponds to the practice of narratives and descriptions ultimately based on indexical self-referential statements, which are in turn rooted in very specific dimensions of human experience.” It is also important to underscore from the outset that the problem of indexical self-reference cannot be separated from Peirce’s concept of experience, which is one of the most interesting insights of Peirce’s philosophy and classical American pragmatism. In particular, it will be essential to see what are the experiential-perceptual conditions under which indexical self-referential statements can work as such. (shrink)

A obra de Dilthey desempenha um papel fundamental para a filosofia contemporânea, na medida em que Dilthey distingue duas esferas por meio das quais temos acesso ao todo da realidade: a experiência objetiva ( die Erfahrung ) e a vivência ( das Erlebnis ). É esta distinçáo que possibilita a Dilthey, em oposiçáo às ciências da natureza, conceber as condições de evidência e validade das ciências do espírito. Ainda que náo nomeada com estes termos, esta distinçáo vai estar na base (...) dos textos de muitos autores do final do século XIX e do século XX. Conquanto Dilthey elabore sua teoria no decorrer de uma vasta obra, nosso objetivo é reconstruir a distinçáo que ele estabelece a partir do modo como ele reinterpreta o princípio de razáo suficiente, conforme formulado por Leibniz e Wolff. Também procuramos mostrar, a seguir, como esta reinterpretaçáo permite a Dilthey opor, à esfera dos conhecimentos teóricos circunscrita por Kant, a esfera dos conhecimentos relativos à vivência. Assim, o argumento principal aqui exposto estabelece um vínculo entre o modo como Dilthey reinterpreta o princípio de razáo suficiente e o modo como reconstrói cientificamente a fundamentaçáo das ciências do espírito, concebendo-as a partir de uma relaçáo específica entre evidência e validade.

The essay aims to analyse the gradual historical process of the partial overlap, replacement and expansion of the theoretical paradigm of depression with respect to that of melancholy. The first part is devoted to analysing some of the central features of the multivalent thematizations of melancholy drawn up during modernity, also with relation to the spirit of capitalism (in its Weberian acceptation). This is followed by an overview of the birth of the modern category of depression, and the process that (...) during the twentieth century led to its transformation into a theoretical and nosological paradigm which in the end replaced that of melancholy. The second part is the attempt to draw up a Zeitdiagnose: the aim is to assess the ‘depressive’ psychosocial impact exercised by particular socio-economic mechanisms and cultural trends, with particular reference to what has been defined as the ‘new spirit of capitalism’, as well as the new forms of individualism and their paradoxical dynamics. In conclusion, I will form a bridge between the history of the two aforesaid paradigms and the contemporary psychosocial dynamics correlated to the phenomenon today interpreted as a ‘depression epidemic’. Il saggio mira ad analizzare il graduale processo storico di parziale sovrapposizione, sostituzione ed ampliamento del paradigma teoretico della depressione rispetto a quello della melanconia. La prima parte è dedicata ad analizzare alcuni dei tratti nevralgici delle polivalenti tematizzazioni della malinconia avvenuti nel corso della modernità, anche in relazione allo spirito del capitalismo (nella sua accezione weberiana). Segue una panoramica sulla nascita della categoria moderna di depressione, e del processo che nel corso del XX secolo l’ha condotta alla sua trasformazione in un paradigma teoretico e nosologico che ha infine sostituito quello della melanconia. La seconda parte rappresenta il tentativo di elaborare una Zeitdiagnose: l’obiettivo è valutare l’impatto psicosociale di natura ‘depressiva’ esercitato da particolari meccanismi socioeconomici e tendenze culturali, con particolare riferimento a ciò che è stato definito il «nuovo spirito del capitalismo», nonché alle nuove forme dell’individualismo e alle loro dinamiche paradossali. In conclusione viene gettato un ponte tra la storia dei due suddetti paradigmi e le dinamiche psicosociali contemporanee correlate al fenomeno oggi interpretato quale «epidemia depressiva». (shrink)

The aim of this paper is to account for the (metaphorical) movement of the property of being present (or presentness) within the so-called Moving Spotlight Theory (MST). I will be leveraging the key argument by Emanuele Severino’s masterpiece, 'La Gloria' (2001), according to which it is impossible that a (maximal consistent) state of affairs begins to appear and lasts forever in our experience. After a brief overview of the MST’s main tenets (§1.1), I argue that Severino’s ontology might be interpreted (...) as a sort of MST (§1.2), following the hint by Federico Perelda (2017). Thereafter, I briefly recall Severino’s original argument in his own jargon, also proposing English lexical and conceptual translations of the main Italian phrases (§1.3). Then, I propose both a semi-formalization of Severino’s argument (§2.1) and a full formalization by means of temporal logic (§2.2). Finally, I assess all the three versions of the argument, concluding that my formalization might account for the movement of presentness in a non-metaphorical way (§2.3). (shrink)

Numerous problems arising in engineering applications can have several objectives to be satisfied. An important class of problems of this kind is lexicographic multi-objective problems where the first objective is incomparably more important than the second one which, in its turn, is incomparably more important than the third one, etc. In this paper, Lexicographic Multi-Objective Linear Programming (LMOLP) problems are considered. To tackle them, traditional approaches either require solution of a series of linear programming problems or apply a scalarization of (...) weighted multiple objectives into a single-objective function. The latter approach requires finding a set of weights that guarantees the equivalence of the original problem and the single-objective one and the search of correct weights can be very time consuming. In this work a new approach for solving LMOLP problems using a recently introduced computational methodology allowing one to work numerically with infinities and infinitesimals is proposed. It is shown that a smart application of infinitesimal weights allows one to construct a single-objective problem avoiding the necessity to determine finite weights. The equivalence between the original multi-objective problem and the new single-objective one is proved. A simplex-based algorithm working with finite and infinitesimal numbers is proposed, implemented, and discussed. Results of some numerical experiments are provided. (shrink)

Many philosophers claim that the neurocomputational framework of predictive processing entails a globally inferentialist and representationalist view of cognition. Here, I contend that this is not correct. I argue that, given the theoretical commitments these philosophers endorse, no structure within predictive processing systems can be rightfully identified as a representational vehicle. To do so, I first examine some of the theoretical commitments these philosophers share, and show that these commitments provide a set of necessary conditions the satisfaction of which allows (...) us to identify representational vehicles. Having done so, I introduce a predictive processing system capable of active inference, in the form of a simple robotic “brain”. I examine it thoroughly, and show that, given the necessary conditions highlighted above, none of its components qualifies as a representational vehicle. I then consider and allay some worries my claim could raise. I consider whether the anti-representationalist verdict thus obtained could be generalized, and provide some reasons favoring a positive answer. I further consider whether my arguments here could be blocked by allowing the same representational vehicle to possess multiple contents, and whether my arguments entail some extreme form of revisionism, answering in the negative in both cases. A quick conclusion follows. (shrink)

In this article, I address a controversial aspect of Rawls’s treatment of the question of justice between generations: how the parties in the original position could be motivated to select Rawls’s preferred principle of intergenerational savings, which he dubs the just savings principle. I focus on the explanation found in his later work, where he proposes that the correct savings principle is the principle that any generation would have wanted preceding generations to have followed. By expanding upon this explanation, I (...) respond to the objection that this explanation disregards the perspective of the first generation. I demonstrate that this objection ceases to be a concern when a proper account of the parties’ reasoning is developed. What is notable about the explanation I defend is that it relies on the parties adopting maximax – not maximin – as a rule for rational decision making. Having established this intermediary conclusion, I depart with Rawls and consider what savings principle the parties would choose if given more options. Ultimately, I argue that the parties would select a principle that Rawls would have undoubtedly rejected if presented to him at face value. This is because the principle of savings I argue would be selected requires continual economic growth over generations to increase upwards indefinitely – a conclusion Rawls is explicitly trying to avoid in his theory of justice.

Some philosophers argue that a theory of logical validity should not interpret its own language, because a Russellian argument shows that self-applicability is inconsistent with the ability to capture all the interpretations of its own language. First, I set up a formal system to examine the Russellian argument. I then defend the need for self-applicability. I argue that self-applicability seems to be implied by generality, and that the Russellian argument rests on a test for meaning that is biased against self-applicability. (...) I propose an alternative test which is unproblematic for self-applicability. I conclude that self-applicability can be vindicated and the Russellian argument can be resisted. (shrink)

A central feature of experimental development economics is the use of randomized controlled trials (RCTs) to evaluate the effectiveness of prospective socioeconomic interventions. The use of RCTs in development economics raises a host of ethical issues which are just beginning to be explored. In this article, I address one ethical issue in particular: the routine use of the status quo as a control when designing and conducting a development RCT. Drawing on the literature on the principle of standard care in (...) medical research ethics, as well as considerations of distributive justice in non-ideal circumstances, I argue that the practice of using the status quo as a control is ethically justifiable. However, I add an important qualification based on the natural duty of rescue to address the concern that my account is overly permissive. (shrink)

The book aims to offer a contribution to the historiographical and conceptual reconfiguration of the evolutionary revolution in the light of the centuries-old tenets of the Aristotelian biological tradition. Darwin’s breakthrough constitutes a thorough overturning of the fixist, essentialist and teleological framework created by Aristotle, a framework still dominant in the 17th Century world of Harvey and Ray, as well as Galileo, and then hegemonic until Linnaeus and Cuvier. This change is exemplified in the morphological analysis of useless parts, such (...) as the sightless eyes of moles, already discussed by Aristotle, and which Darwin used almost like a crowbar to unhinge the systematic recourse to final causes. This is an ancient teleological heritage present in various forms in the concept of natural selection, but by then confined within an eminently historical framework open to randomness. Un contributo alla riconfigurazione storiografica e concettuale della rivoluzione evoluzionistica alla luce della tenuta plurisecolare della tradizione biologica aristotelica. La svolta di Darwin si delinea quale puntuale rovesciamento dell'impianto fissista, essenzialista e teleologico coniato da Aristotele, ancora dominante nel Seicento di Harvey e di Ray, nonostante Galileo, e poi egemone fino a Linneo e Cuvier. Svolta esemplificata dall'analisi morfologica delle parti inutili, come gli occhi ciechi della talpa, tematizzate già da Aristotele, e che Darwin usò quale grimaldello per scardinare il ricorso sistematico alle cause finali. Antica eredità teleologica presente in varie forme nel concetto di selezione naturale, ma ormai calata entro una griglia eminentemente storica e aperta alla casualità. (shrink)

(T I, II, IV, 8). Essa afirmação de Hume é forte, programática, feita em um parágrafo de pouco mais de cinco linhas. Nada o prepara, e Hume não explica em pormenor suas intenções na sequência imediata desse texto. Por isso, tomamos essa questão como foco da análise. Inicialmente examinaremos esse problema em Bayle, destacando passagens que possam lançar luz às críticas feitas por Hume e tornar compreensíveis as discussões que empreendeu. A seguir, a partir de duas respostas dadas por Hume a esse problema, colhido dentro do Tratado, procuraremos explicitar o que Hume entende por definições, o que designa por demonstrações, e por qual modo julga que isso lhe permitiria tratar os fundamentos da geometria de modo mais consequente do que aquele pelo qual estes tinham sido compreendidos no interior de uma longa tradição.

[This is a pre-print; please cite the published version] This paper employs structural topic modeling (STM) to describe the academic philosophy landscape in Brazil. Based on a public national database, a corpus consisting of 12,515 abstracts of monographs defended in philosophy graduate programs between 1991 and 2021 was compiled. The final STM model identified 74 meaningful research topics, clustered into 7 thematic categories. This study discusses the prevalence of the most significant topics and categories, their trends across three decades, and (...) their (positive or negative) association with the supervisor's gender. Results show the first empirical evidence that Brazilian philosophical research exhibits a greater focus on philosophers than on specific themes or problems. Moreover, by visualizing the variations in topic prevalence over time, it was possible to track the rise or decline of the major interest categories and topics. Finally, results also show which topics are more influenced or less influenced by gender. (shrink)

According to the interpretational theory of logical validity (IR), logical validity is preservation of truth in all interpretations compatible with the intended meaning of logical expressions. IR suffers from a seemingly defeating objection, the so-called cardinality problem: any instance of the statement ‘There are n things’ is true under all interpretations, since it can be written down using only logical expressions that are not to be reinterpreted; yet ‘There are n things’ is not logically true. I argue that the cardinality (...) problem is indeed a serious problem for IR, when understood in terms of ‘asymmetry of information’. I then argue that IR can be rehabilitated by making quantifiers context-sensitive: what we do not reinterpret is the Kaplanian character of a quantifier, rather than its content. ‘There are n things’ is false in a context where fewer than n things are relevant, so it is not logically true in IR. I finally discuss some objections and ramifications of my account: I discuss how to make space for the possibility of an explicitly absolutely general quantifier in my framework, how terms can be logical even though context-sensitive, and how to recapture classical logic within my framework.

In the substitutional framework, validity is truth under all substitutions of the nonlogical vocabulary. I develop a theory where □ is interpreted as substitutional validity. I show how to prove soundness and completeness for common modal calculi using this definition.

The aim of this paper is to present the copy principle from execution of the principle of separability for the purpose of elucidating the discussions conducted by Hume in understanding the composition of space and its implications for the sciences that operate with spatial constructions. The particular epistemic gain here is to do this within a model of empiricism. Given that there are several irregularities in the manner of analyzing a complex and extracting simple elements from it, as will be (...) demonstrated here, we seek to show that separating a complex considering its simple qualities and decomposing a complex to determine its simple quantities is completely different. Thus, we seek to show how Hume needed to recreate his own cognitive model, strongly based on noting our perceptions, to be able to use it to conceive the composition of space and the operations of geometry that must make reference to it.
