2024 marks the 400th anniversary of the publication of Theodor Smising’s giant volume De Deo Uno (printed in Antwerp in 1624), which was soon followed by a second volume, De Deo Trino (printed in Antwerp in 1626). Smising’s work was the first printed output of what developed into a specific tradition within early modern thought, the Louvain tradition of Scotism, itself but one part of the broad Scotist tradition that build upon the thought of John Duns Scotus (ca. 1266–1308). This (...) Louvain tradition was primarily based in the Franciscan Convent of the Holy Trinity in the famous university town. The convent itself was much older, dating back to around 1230, when the Franciscan Order was in its very beginnings and long before the University of Louvain was founded (in 1425). In 1607 a second Franciscan Convent was founded in Louvain, St. Anthony’s College, one of a series of convents established by the Irish Franciscans as a result of their persecution in their homeland by the English Protestant rulers. The Irish Franciscans in Louvain, and in their other convents on the European continent, also cultivated the intellectual heritage of Duns Scotus, editing and commenting on his works and writing new works “ad mentem Scoti.” Both of the Franciscan convents in Louvain were closed in the turmoil after the French Revolution. The buildings of St. Anthony’s College still exist, whereas the older “Minderbroedersklooster” (on our exhibition poster) completely vanished from the cityscape. In recent decades, the Maurits Sabbe Library has acquired a large fund of Franciscan books, mostly from various houses of the Franciscan Order in Belgium that have closed their doors. Our exhibition “Scotism Made in Louvain – The Scholastic Culture of the Franciscans in Belgium” explores this material, complemented by material from the KU Leuven Central Library’s Special Collections and two manuscripts from the archives of KADOC (Documentatie- en Onderzoekscentrum voor Religie, Cultuur en Samenleving). The exhibition tells the story of a significant local scholarly tradition which is placed in the context of the broader Scotist tradition of the Early Modern Period. Whereas Scholasticism as such is often seen as an exclusively medieval phenomenon, our exhibition highlights one important aspect of early modern scholastic culture. The three brief articles included in this catalogue provide an introduction to John Duns Scotus’s thought, investigate the institutional background of Louvain Scotism, and explore some of the most important aspects of the scholastic output of the Franciscans in Louvain. The numbers attached to the images refer to the annotated list of all exhibits. A virtual exhibition with additional photo material will accompany, and last beyond, the library exhibition. (shrink)

By formalizing some classical facts about provably total functions of intuitionistic primitive recursive arithmetic (iPRA), we prove that the set of decidable formulas of iPRA and of iΣ1+ (intuitionistic Σ1-induction in the language of PRA) coincides with the set of its provably ∆1-formulas and coincides with the set of its provably atomic formulas. By the same methods, we shall give another proof of a theorem of Marković and De Jongh: the decidable formulas of HA are its provably ∆1-formulas.

This paper examines the role of prestige bias in shaping academic philosophy, with a focus on its demographics. I argue that prestige bias exacerbates the structural underrepresentation of minorities in philosophy. It works as a filter against (among others) philosophers of color, women philosophers, and philosophers of low socio-economic status. As a consequence of prestige bias our judgments of philosophical quality become distorted. I outline ways in which prestige bias in philosophy can be mitigated.

People suffering from Obsessive-Compulsive Disorder (OCD) do things they do not want to do, and/or they think things they do not want to think. In about 10 percent of OCD patients, none of the available treatment options is effective. A small group of these patients is currently being treated with deep brain stimulation (DBS). Deep brain stimulation involves the implantation of electrodes in the brain. These electrodes give a continuous electrical pulse to the brain area in which they are implanted. (...) It turns out that patients may experience profound changes as a result of DBS treatment. It is not just the symptoms that change; patients rather seem to experience a different way of being in the world. These global effects are insufficiently captured by traditional psychiatric scales, which mainly consist of behavioural measures of the severity of the symptoms. In this article we aim to capture the changes in the patients’ phenomenology and make sense of the broad range of changes they report. For that we introduce an enactive, affordance-based model that fleshes out the dynamic interactions between person and world in four aspects. The first aspect is the patients’ experience of the world. We propose to specify the patients’ world in terms of a field of affordances, with the three dimensions of broadness of scope (‘width’ of the field), temporal horizon (‘depth’), and relevance of the perceived affordances (‘height’). The second aspect is the person-side of the interaction, that is, the patients’ self-experience, notably their moods and feelings. Thirdly, we point to the different characteristics of the way in which patients relate to the world. And lastly, the existential stance refers to the stance that patients take towards the changes they experience: the second-order evaluative relation to their interactions and themselves. With our model we intend to specify the notion of being in the world in order to do justice to the phenomenological effects of DBS treatment. (shrink)

Criteria of acceptability for mathematical proofs are field-dependent. In topology, though not in most other domains, it is sometimes acceptable to appeal to visual intuition to support inferential steps. In previous work :829–842, 2014; Lolli, Panza, Venturi From logic to practice, Springer, Berlin, 2015; Larvor Mathematical cultures, Springer, Berlin, 2016) my co-author and I aimed at spelling out how topological proofs work on their own terms, without appealing to formal proofs which might be associated with them. In this article, I (...) address two criticisms that have been raised in Tatton-Brown against our approach: that it leads to a form of relativism according to which validity is equated with social agreement and that it implies an antiformalizability thesis according to which it is not the case that all rigorous mathematical proofs can be formalized. I reject both criticisms and suggest that our previous case studies provide insight into the plausibility of two related but quite different theses. (shrink)

This paper has a twofold aim. On the one hand, we will discuss the much debated question of the source of normativity (which traditionally has nature and practical reason as the two main contenders to this role) and propose a new answer to it. Second, in answering this question, we will present a new account of practical wisdom, which conceives of the ethical virtues as ultimately unified in the chief virtue of phronesis, understood as ethical expertise. To do so, we (...) will first criticize the main current view of phronesis and its bearer (the phronimos), then offer another view of the nature of phronesis and of its relation to the other ethical virtues. Our proposal should not be intended as an interpretation of Aristotle’s own view; rather, it should be seen as a broadly Aristotelian theoretical proposal, which we believe can satisfyingly address most of the problems that afflict the more traditional accounts of practical wisdom. In section 2 of this paper, after criticizing first-nature naturalistic views of moral virtue, we take practical reason to be the cornerstone of second-nature naturalistic views; in section 3, we will outline criticisms to which, in our view, the traditional views of phronesis are ill-suited to respond, and, in section 4, we will outline our view of phronesis as ethical expertise – a view which in our view is immune to the above-mentioned criticisms – by spelling out the three main tenets of phronesis as ethical expertise: a conceptual thesis, an epistemic thesis, and the educational implications of the two. Finally, we will support our proposal with some empirical evidence taken from cognitive science. (shrink)

During the first half of the twentieth century, many philosophers of memory opposed the postulation of memory traces based on the claim that a satisfactory account of remembering need not include references to causal processes involved in recollection. However, in 1966, an influential paper by Martin and Deutscher showed that causal claims are indeed necessary for a proper account of remembering. This, however, did not settle the issue, as in 1977 Malcolm argued that even if one were to buy Martin (...) and Deutscher’s argument for causal claims, we still don’t need to postulate the existence of memory traces. This paper reconstructs the dialectic between realists and anti-realists about memory traces, suggesting that ultimately realists’ arguments amount to inferences to the best explanation. I then argue that Malcolm’s anti-realist strategy consists in the suggestion that causal explanations that do not invoke memory traces are at least as good as those that do. But then, Malcolm, I argue that there are a large number of memory phenomena for which explanations that do not postulate the existence of memory traces are definitively worse than explanations that do postulate them. Next, I offer a causal model based on an interventionist framework to illustrate when memory traces can help to explain memory phenomena and proceed to substantiate the model with details coming from extant findings in the neuroscience of memory.

Recent experimental evidence from developmental psychology and cognitive neuroscience indicates that humans are equipped with unlearned elementary mathematical skills. However, formal mathematics has properties that cannot be reduced to these elementary cognitive capacities. The question then arises how human beings cognitively deal with more advanced mathematical ideas. This paper draws on the extended mind thesis to suggest that mathematical symbols enable us to delegate some mathematical operations to the external environment. In this view, mathematical symbols are not only used to (...) express mathematical concepts—they are constitutive of the mathematical concepts themselves. Mathematical symbols are epistemic actions, because they enable us to represent concepts that are literally unthinkable with our bare brains. Using case-studies from the history of mathematics and from educational psychology, we argue for an intimate relationship between mathematical symbols and mathematical cognition. (shrink)

Rigorous proof is supposed to guarantee that the premises invoked imply the conclusion reached, and the problem of rigor may be described as that of bringing together the perspectives of formal logic and mathematical practice on how this is to be achieved. This problem has recently raised a lot of discussion among philosophers of mathematics. We survey some possible solutions and argue that failure to understand its terms properly has led to misunderstandings in the literature.

If there is an area of discourse in which disagreement is virtually absent, it is mathematics. After all, mathematicians justify their claims with deductive proofs: arguments that entail their conclusions. But is mathematics really exceptional in this respect? Looking at the history and practice of mathematics, we soon realize that it is not. First, deductive arguments must start somewhere. How should we choose the starting points (i.e., the axioms)? Second, mathematicians, like the rest of us, are fallible. Their ability to (...) recognize whether a putative proof is correct is not infallible. In most cases, disagreement over the correctness of a putative proof is, however, evanescent. Once an error is spotted and communicated, the disagreement disappears. But this is not always the case. Sometimes it is recalcitrant; that is, it persists over time. In order to zoom in on this type of disagreement and explain its very possibility, we focus on a single case study: a decades-long (1921-1949) controversy between Federigo Enriques and Francesco Severi, two prominent exponents of the Italian school of algebraic geometry. We suggest that the instability of the mathematical community to which they belonged can be explained by the gap between an abstract criterion of rigor and local criteria of acceptability. It is this instability that made the existence of recalcitrant disagreement over putative proofs possible. We do not condemn speculative mathematics but rather its pretense of being rigorous mathematics. In this respect, we show that the overly self-confident Severi and the more intuitive, visionary Enriques had a completely different attitude. (shrink)

According to some collectivists, purposive groups that lack decision-making procedures such as riot mobs, friends walking together, or the pro-life lobby can be morally responsible and have moral duties. I focus on plural subject- and we-mode-collectivism. I argue that purposive groups do not qualify as duty-bearers even if they qualify as agents on either view. To qualify as a duty-bearer, an agent must be morally competent. I develop the Update Argument. An agent is morally competent only if the agent has (...) sufficient positive and negative control over updating their goal-seeking states. Positive control involves the general ability to update one’s goal-seeking states, whereas negative control involves the absence of other agents with the capacity to arbitrarily interfere with updating one’s goal-seeking states. I argue that even if purposive groups qualify as plural subjects or we-mode group agents, these groups necessarily lack negative control over updating their goal-seeking states. This creates a cut-off point for groups as duty-bearers: Organized groups may qualify as duty-bearers, whereas purposive groups cannot qualify as duty-bearers. (shrink)

I highlight three features of P.F. Strawson’s later, neglected work on freedom and responsibility. First, in response to a criticism by Rajendra Prasad, Strawson explicitly rejects an argument put forward in ‘Freedom and Resentment’ against the relevance of determinism to moral responsibility. Second, his remarkable acceptance of Prasad’s criticism motivates him to take the ‘straight path’, that is, to be straightforward about the relation between determinism, freedom, the ability to do otherwise and the conditions of responsibility. He claims that the (...) ability to do otherwise is a necessary condition of responsibility and provides a list of additional conditions, including a knowledge condition. Third, he clarifies the relation between responsibility, quality of will and the reactive attitudes. The latter do not figure essentially in his answer to the question, ‘What are the conditions of responsibility?’, but they do play an essential role in his answer to the question, ‘Why do we have the concept of responsibility?’ We have it, Strawson suggests, because of our natural concern about the quality of will with which people act, a concern expressed in our reactive attitudes. I argue that, although Strawson’s later work definitely involves a shift of emphasis when compared to ‘Freedom and Resentment’, his overall account of freedom and responsibility is coherent. The later work helps to better understand the nature and significance of Strawson’s contribution, and to identify problems with common interpretations of and objections to ‘Freedom and Resentment’.

Religious disagreement is an emerging topic of interest in social epistemology. Little is known about how philosophers react to religious disagreements in a professional context, or how they think one should respond to disagreement. This paper presents results of an empirical study on religious disagreement among philosophers. Results indicate that personal religious beliefs, philosophical training, and recent changes in religious outlook have a significant impact on philosophers' assessments of religious disagreement. They regard peer disagreement about religion as common, and most (...) surveyed participants assume one should accord weight to the other's opinion. Theists and agnostics are less likely to assume they are in a better epistemic position than their interlocutors about religious questions compared with atheists, but this pattern only holds for participants who are not philosophers of religion. Continental philosophers think religious beliefs are more like preferences than analytic philosophers, who regard religious beliefs as fact-like. (shrink)

The knower paradox states that the statement ‘We know that this statement is false’ leads to inconsistency. This article presents a fresh look at this paradox and some well-known solutions from the literature. Paul Égré discusses three possible solutions that modal provability logic provides for the paradox by surveying and comparing three different provability interpretations of modality, originally described by Skyrms, Anderson, and Solovay. In this article, some background is explained to clarify Égré’s solutions, all three of which hinge on (...) intricacies of provability logic and its arithmetical interpretations. To check whether Égré’s solutions are satisfactory, we use the criteria for solutions to paradoxes defined by Susan Haack and we propose some refinements of them. This article aims to describe to what extent the knower paradox can be solved using provability logic and to what extent the solutions proposed in the literature satisfy Haack’s criteria. Finally, the article offers some reflections on the relation between knowledge, proof, and provability, as inspired by the knower paradox and its solutions. (shrink)

There is widespread excitement in the literature about the method of arbitrary functions: many take it to show that it is from the dynamics of systems that the objectivity of probabilities emerge. In this paper, I differentiate three ways in which a probability function might be objective, and I argue that the method of arbitrary functions cannot help us show that dynamics objectivise probabilities in any of these senses.

Void is at the heart of Stoic metaphysics. As the incorporeal par excellence, being defined purely in terms of lacking body, it brings into sharp focus the Stoic commitment to non-existent Somethings. This article argues that Stoic void, far from rendering the Stoic system incoherent or merely ad hoc, in fact reflects a principled and coherent physicalism that sets the Stoics apart from their materialist predecessors and atomist neighbors.

An intuitive objection to modal realism is that merely possible worlds and their inhabitants seem to be irrelevant to an analysis of modality. Kripke originally phrased the objection in terms of being concerned about one’s modal properties without being concerned about the properties one’s other-worldly counterparts have. The author assesses this objection in a variety of forms, and then provides his own formulation that does not beg the question against the modal realist. Finally, the author considers two potential answers to (...) the objection so understood and concludes that only one of them has a chance of succeeding. (shrink)

Despite their divergent metaphysical assumptions, Reformed and evolutionary epistemologists have converged on the notion of proper basicality. Where Reformed epistemologists appeal to God, who has designed the mind in such a way that it successfully aims at the truth, evolutionary epistemologists appeal to natural selection as a mechanism that favors truth-preserving cognitive capacities. This paper investigates whether Reformed and evolutionary epistemological accounts of theistic belief are compatible. We will argue that their chief incompatibility lies in the noetic effects of sin (...) and what may be termed the noetic effects of evolution, systematic tendencies wherein human cognitive faculties go awry. We propose a reconceptualization of the noetic effects of sin to mitigate this tension. (shrink)

Natural theology is the branch of theology and philosophy that attempts to gain knowledge of God through non-revealed sources. In a narrower sense, natural theology is the discipline that presents rational arguments for the existence of God. Given that these arguments rarely directly persuade those who are not convinced by their conclusions, why do they enjoy an enduring appeal? This article examines two reasons for the continuing popularity of natural theological arguments: (i) they appeal to intuitions that humans robustly hold (...) and that emerge early in cognitive development; (ii) they serve an argumentative function by presenting particular religious views as live options. I conclude with observations on the role of natural theology in contemporary analytic philosophy of religion. (shrink)

In this paper, we argue that knowledge of emotions essentially depends on introspecting the phenomenology of emotional experiences, and that introspection of emotional experiences is a process by stages, where the most fundamental stage is a non-classificatory introspective state, i.e., one that does not depend on the subject’s classifying the introspected emotion as an instance of any experience type. We call such a non-classificatory kind of introspection primitive introspection. Our main goal is to show that, although not sufficient, primitive introspection (...) is a necessary ground to acquire knowledge of emotions. Our main argument is phenomenological: by examining a variety of examples, we suggest that an accurate analysis of the introspective process through which one comes to know, or refines one’s knowledge of, one’s current emotion requires that one primitively introspects it.

Este trabalho apresenta algumas considerações a respeito da Base Nacional Comum Curricular (BNCC), no referente às questões ligadas ao ensino da língua portuguesa no Brasil, à territorialidade e ao pertencimento racial, processos históricos, que envolvem, no campo da educação, a formação docente e a construção da cidadania dos educandos e das educandas nestes tempos de reafirmação do Estado democrático de direito e da vaga decolonial. Portanto, trata-se de uma abordagem política em termos do pensamento de Paulo Freire, patrono da educação (...) brasileira, que considerava político o ato de educar (FREIRE, 1980; 1983; 1989; 1996). É com base nesta perspectiva que a BNCC será abordada, mas sob o aporte teórico da análise pragmática do discurso, tributária da análise discursivo-desconstrutiva (cf. ARAÚJO, 2020). (shrink)

This collection addresses two different audiences: 1) historians and philosophers of the life sciences reflecting on collaborations across disciplines, especially as regards defining and addressing Grand Challenges; 2) researchers and other stakeholders involved in cross-disciplinary collaborations aimed at tackling Grand Challenges in the life and medical sciences. The essays collected here offer ideas and resources both for the study and for the practice of goal-driven cross-disciplinary research in the life and medical sciences. We organise this introduction in three sections. The (...) first section provides some background and context. The second motivates our take on this topic and then outlines the central ideas of each paper. The third section highlights the specificity and significance of this approach by considering: a) how this collection departs from existing literature on inter- and trans-disciplinarity, b) what is characteristic about this approach, and c) what role this suggests for the history and philosophy of the life sciences in addressing Grand Challenges.

The Stoics are famously committed to the thesis that only bodies are, and for this reason they are rightly called “corporealists.” They are also famously compared to Plato’s earthborn Giants in the Sophist, and rightly so given their steadfast commitment to body as being. But the Stoics also notoriously turn the tables on Plato and coopt his “dunamis proposal” that being is whatever can act or be acted upon to underwrite their commitment to body rather than shrink from it as (...) the Giants do. The substance of Stoic corporealism, however, has not been fully appreciated. This paper argues that Stoic corporealism goes beyond the dunamis proposal, which is simply an ontological criterion for being, to the metaphysics of body. This involves, first, an account of body as metaphysically simple and hence fundamental; second, an account of body as malleable and continuous, hence fit for blending (krasis di’ holou) and composition. In addition, the metaphysics of body involves a distinction between this composition relation seen in the cosmology, and the constitution relation by which the four-fold schema called the Stoic Categories proceeds, e.g. the relation between a statue and its clay, or a fist and its underlying hand. It has not been appreciated that the cosmology and the Categories are distinct — and complementary — explanatory enterprises, the one accounting for generation and unity, the other taking those individuals once generated, and giving a mereological analysis of their identity and persistence conditions, kinds, and qualities. The result is an elegant division of Plato’s labor from the Battle of Gods and Giants. On the one hand, the Stoics rehabilitate the crude cosmology of the Presocratics to deliver generation and unity in completely corporeal terms, and that work is found in their Physics. On the other hand, they reform the Giants and “dare to corporealize,” delivering all manner of predication (from identity to the virtues), and that work is found in Stoic Logic. Recognizing the distinctness of these explanatory enterprises helps dissolve scholarly puzzles, and harmonizes the Stoics with themselves. (shrink)

Proponents of moral enhancement believe that we should pursue and apply biotechnological means to morally enhance human beings, as failing to do so is likely to lead to humanity's demise. Unsurprisingly, these proposals have generated a substantial amount of debate about the moral permissibility of using such interventions. Here I put aside concerns about the permissibility of moral enhancement and focus on the conceptual and evidentiary grounds for the moral enhancement project. I argue that such grounds are quite precarious.

A new reprogenetic technology, mitochondrial replacement, is making its appearance and, unsurprisingly given its promise to wash off our earthly stains --or at least the scourges of sexual reproduction--, John Harris finds only reasons to celebrate this new scientific feat.1 In fact, he finds mitochondrial replacement techniques (MRTs) so “unreservedly welcome” that he believes those who reject them suffer from “a large degree of desperation and not a little callousness.”2 Believing myself to be neither desperate nor callous, but finding myself (...) also no closer at all – not even after reading his article—to following Harris in welcoming these technologies wholeheartedly, it seems appropriate to respond.

In “Correspondence to Reality in Ethics”, Mario Brandhorst examines the view of ethics that Wittgenstein took in his later years. According to Brandhorst, Wittgenstein leaves room for truth and falsity, facts, correspondence and reality in ethics. Wittgenstein's target, argues Brandhorst, is objectivity. I argue that Brandhorst's arguments in favour of truth, facts, reality and correspondence in ethics invite similar arguments in favour of objectivity, that Brandhorst does not recognise this because his conception of objectivity is distorted by a Platonist picture (...) and that he misinterprets the passage which he takes to support a Wittgensteinian case against objectivity.

The ideas behind open source software are currently applied to the production of encyclopedias. A sample of six English text-based, neutral-point-of-view, online encyclopedias of the kind are identified: h2g2, Wikipedia, Scholarpedia, Encyclopedia of Earth, Citizendium and Knol. How do these projects deal with the problem of trusting their participants to behave as competent and loyal encyclopedists? Editorial policies for soliciting and processing content are shown to range from high discretion to low discretion; that is, from granting unlimited trust to limited (...) trust. Their conceptions of the proper role for experts are also explored and it is argued that to a great extent they determine editorial policies. Subsequently, internal discussions about quality guarantee at Wikipedia are rendered. All indications are that review and ?super-review? of new edits will become policy, to be performed by Wikipedians with a better reputation. Finally, while for encyclopedias the issue of organizational trust largely coincides with epistemological trust, a link is made with theories about the acceptance of testimony. It is argued that both non-reductionist views (the ?acceptance principle? and the ?assurance view?) and reductionist ones (an appeal to background conditions, and a?newly defined??expertise view?) have been implemented in editorial strategies over the past decade.

In recent attempts to define ‘harm’, the most promising approach has often been thought to be the counterfactual comparative account of harm. Nevertheless, this account faces serious difficulties. Moreover, it has been argued that ‘harm’ cannot be defined without reference to a substantive theory of well-being, which is itself a fraught issue. This has led to the call for the concept to simply be dropped from the moral lexicon altogether. I reject this call, arguing that the non-comparative approach to defining (...) harm has not been sufficiently explored. I then develop such an account that avoids the difficulties faced by comparative accounts whilst not presupposing a substantive theory of well-being. I conclude that this definition renders a concept of harm that can be meaningfully employed in our moral discourse. (shrink)

Philosophy of religion is often regarded as a philosophical discipline in which irrelevant influences, such as upbringing and education, play a pernicious role. This paper presents results of a qualitative survey among academic philosophers of religion to examine the role of such factors in their work. In light of these findings, I address two questions: an empirical one (whether philosophers of religion are influenced by irrelevant factors in forming their philosophical attitudes) and an epistemological one (whether the influence of irrelevant (...) factors on our philosophical views should worry us). My answer to the first question is a definite yes, my answer to the second, a tentative yes. (shrink)

The expression “repressed memory” was introduced over 100 years ago as a theoretical term purportedly referring to an unobservable psychological entity postulated by Freud's seduction theory. That theory, however, and its hypothesized cognitive architecture, have been thoroughly debunked—yet the term “repressed memory” seems to remain. In this paper, I offer a philosophical evaluation of the meaning of this theoretical term as well as an argument to question its scientific status by comparing it to other cases of theoretical terms that have (...) either survived scientific change—such as “atom” or “gene”—or that have perished, such as “black bile.” Ultimately, I argue that “repressed memory” is more like “black bile” than “atom” or “gene” and, thus, recommend its demotion from our scientific vocabulary.

Florianópolis: NEL/UFSC, 2011. p. 186-201. (Coleção rumos da epistemologia; 11). Através da análise do pensamento de Isaac Newton (1642-1727) encontramos os postulados metafísicos que fundamentam a sua mecânica natural. Ao deduzir causa de efeito, ele acreditava chegar a uma causa primeira de todas as coisas. A essa primeira causa de tudo, onde toda a ordem e leis (...) tiveram início, a qual para ele assume um caráter divino, Newton aponta para um Deus sábio e poderoso e responsável pela ordem inteligente e pela a harmonia das leis físicas e universais de tudo o que existe – Deus como criador e preservador da ordem do universo. Há ainda a analogia do conceito de Deus com o espaço e o tempo, na medida em que ambos comunicam infinitude e onipresença. Por fim, nas considerações finais apontarei a importância de Newton para a metafísica moderna e como os seus estudos contribuíram para uma visão posterior do universo e suas leis e do homem enquanto ser pensante.

This paper rehabilitates the Stoic conception of blending from the ground up, by freeing the Stoic conception of body from three interpretive presuppositions. First, the twin hylomorphic presuppositions that where there is body there is matter, and that where there is reason or quality there is an incorporeal. Then, the atomistic presupposition that body is absolutely full and rigid, and the attendant notion that resistance (antitupia) must be ricochet. I argue that once we clear away these presuppositions about body, the (...) foundations of Stoic corporealism fall into place. Body is fundamental (not hylomorphic). The two fundamental principles (archai) are bodies: divine active reason (logos) and passive matter (hulē); and these two bodies are two, not matter and form all over again, nor actual and potential, but agent and patient. The independence of the two archai is no threat to the unity of the cosmos, however, because the Stoic theory of body allows for the complete coextension of the archai. The hylomorphic thinker rightly asks, what relation could be tighter than that of the wax and its shape? The Stoic replies: a causal relation, the interaction of agent and patient completely coextended in a through and through blend. (shrink)

Open-content communities that focus on co-creation without requirements for entry have to face the issue of institutional trust in contributors. This research investigates the various ways in which these communities manage this issue. It is shown that communities of open-source software—continue to—rely mainly on hierarchy (reserving write-access for higher echelons), which substitutes (the need for) trust. Encyclopedic communities, though, largely avoid this solution. In the particular case of Wikipedia, which is confronted with persistent vandalism, another arrangement has been pioneered instead. (...) Trust (i.e. full write-access) is ‘backgrounded’ by means of a permanent mobilization of Wikipedians to monitor incoming edits. Computational approaches have been developed for the purpose, yielding both sophisticated monitoring tools that are used by human patrollers, and bots that operate autonomously. Measures of reputation are also under investigation within Wikipedia; their incorporation in monitoring efforts, as an indicator of the trustworthiness of editors, is envisaged. These collective monitoring efforts are interpreted as focusing on avoiding possible damage being inflicted on Wikipedian spaces, thereby being allowed to keep the discretionary powers of editing intact for all users. Further, the essential differences between backgrounding and substituting trust are elaborated. Finally it is argued that the Wikipedian monitoring of new edits, especially by its heavy reliance on computational tools, raises a number of moral questions that need to be answered urgently.

If possible worlds are conjunctions of states of affairs, as in David Armstrong’s combinatorial theory, then is the empty world to be thought of as the null conjunction of states of affairs? The proposal seems plausible, and has received support from David Efird, Tom Stoneham, and Armstrong himself. However, in this paper, it is argued that the proposal faces a trilemma: either it leads to the absurd conclusion that the actual world is empty; or it reduces to a familiar representation (...) of the empty world in which the concept of a null conjunction plays no role; or it needs to make room for the null individual of certain non-classical mereologies.

Recent work in moral psychology that claims to show that human beings make moral judgements on the basis of multiple, divergent moral foundations has been influential in both moral psychology and moral philosophy. Primarily, such work has been taken to undermine monistic moral theories, especially those pertaining to the prevention of harm. Here, I call one of the most prominent and influential empirical cases for moral pluralism into question, namely that of Jonathan Haidt and his colleagues. I argue that Haidt (...) et al.’s argument is not as strong as it is often made out to be, given significant problems with the design of one of the key experiments used to ground the claim that there are divergent moral foundations across cultures. The flaws that I point out pose a significant challenge to Haidt et al.’s findings and have a detrimental impact on subsequent work based on this immensely influential experiment. Accordingly, I argue that both empirical and normative claims made on the basis of Haidt et al.’s findings should be treated with caution. I conclude by making some suggestions as to how some of the problems that I point out might be addressed. (shrink)

In this article, rewilding’s orientation towards the past is discussed. A response is given to the criticisms that condemn rewilding for its retrospectivity, either as nostalgically clinging to the past or escaping history. Instead, it is shown how rewilding can embrace nostalgia as part of a critical, (counter-)cultural vision aimed at the transformation of modern culture. Its main goal can be seen as threefold: first, it is aimed at providing a more nuanced assessment of rewilding’s contested stance towards the past (...) (and thereby, the future) through the lens of nostalgia. Second, it is demonstrated how, seen through this lens, cultural and ecological aspects of rewilding appear inextricably intertwined. Third, the concepts of ‘cultural rewilding’ and ‘recovery’ are introduced as valuable notions within rewilding. In sum, an appeal is provided for rewilders to embrace the past by dedicating attention towards cultural heritage, history, memory, and tradition. (shrink)

In this essay I explore the resources Thomas Aquinas provides for enquiries concerning the psychological abilities of nonhuman animals. I first look to Aquinas’s account of divine, angelic, human, and nonhuman animal naming, to help us articulate the contours of a ‘critical anthropocentrism’ that aims to steer clear of the mistakes of a na¨ıve anthropocentrism and misconceived avowals to entirely eschew anthropocentrism. I then address the need for our critical anthropocentrism both to reject the mental-physical dichotomy endorsed by ‘folk psychology’ (...) and to articulate a more adequate ‘commonsense psychology’ that acknowledges most embodied animal behavior is observable psychological behavior. Next, I argue that we can develop Aquinas’s doctrine of estimation and conation to formulate an account of nonhuman animal action that more adequately characterizes the purposeful behaviors of nonhuman animals. To do so, we first need to recognize a wider range of nonhuman animal behaviors that are captured by Aquinas’s ‘estimative sense’, and that all of these behaviors are specified by a finite variety of particular goods confined to the animals’ environmental niches. But we also need to supplement Aquinas’s account of human and nonhuman animal agency by exploring the ontogeny and ecology of how humans and other animals become attuned to affordances within these different environmental niches. I argue that we should look to Aquinas’s account of nonhuman animal capacities in ST I-II 6-17 for subtle insights that can expand our understanding of how nonhuman animals engage in purposeful behavior by exercising analogous nonrational and imperfectly voluntary forms of intention, deliberation, choice, execution, and enjoyment. I conclude with an outline for how future enquiry can seek to explain the nonrational purposeful problem-solving competencies of chimps, canines, corvids, cetaceans, cephalopods, and other nonhuman animal species.

The concept of “harm” is ubiquitous in moral theorising, and yet remains poorly defined. Bradley suggests that the counterfactual comparative account of harm is the most plausible account currently available, but also argues that it is fatally flawed, since it falters on the omission and pre-emption problems. Hanna attempts to defend the counterfactual comparative account of harm against both problems. In this paper, I argue that Hanna’s defence fails. I also show how his defence highlights the fact that both the (...) omission and the pre-emption problems have the same root cause – the inability of the counterfactual comparative account of harm to allow for our implicit considerations regarding well-being when assessing harm. While its purported neutrality with regard to substantive theories of well-being is one of the reasons that this account is considered to be the most plausible on offer, I will argue that this neutrality is illusory.

Numerous studies of the beliefs of people with anorexia nervosa (AN) suggest that a subset of such individuals may experience delusions. We first describe what makes a belief delusional and conclude that such characteristics can be appropriately applied to some beliefs of people with AN. Next, we outline how delusional beliefs may relate to the broader psychopathological process in AN, including: (1) they may be epiphenomenal; (2) they may be an initial partial cause of AN; (3) they may be caused (...) by aspects of AN; or (4) they may be sustaining causes, possibly involved in reciprocal causal relations with aspects of AN. We argue that there is good reason to believe that delusional beliefs of people with AN are not merely epiphenomenal, but rather that they’re causally connected to AN. Because of this, empirical studies can be designed to test for the presence of causal relations. We describe how these studies should be designed. The results of such studies have important implications for understanding the experience of individuals with AN and for the treatment of AN. We outline these implications. (shrink)

This article, the second of a two-part essay, outlines a solution to certain tensions in Thomist philosophical anthropology concerning the interaction of the human person’s immaterial intellectual or noetic operations with the psychosomatic sensory operations that are constituted from the formal organization of the nervous system. Continuing with where the first part left off, I argue that Thomists should not be tempted by strong emergentist accounts of mental operations that act directly on the brain, but should maintain, with Aquinas, that (...) noetic operations directly interact with psychosomatic operations. I develop a Thomist account of noetic–psychosomatic interactions that expands upon the first part’s rapprochement between the new mechanist philosophy of neuroscience and psychology and hylomorphic animalism. I argue that noetic–psychosomatic interactions are best understood as analogous to the way diverse higher and lower order psychosomatic powers interact by actualizing, coordinating, and directing the operations of other psychosomatic powers. I draw on James Ross’s arguments for the immateriality of intellectual operations as realizing definite pure functions in order to elucidate the way noetic operations uniquely actualize, coordinate, and direct the psychosomatic operations they interact with. I conclude with a conjectural sketch of how this presentation of Thomist philosophical anthropology understands the noetic and psychosomatic deficits brought about by damage to the nervous system.

This paper discusses opposite philosophical approaches to the body and its position in the ethical discussion; in particular, the perception of the body's capability of achieving ethical excellence. One of the viewpoints in question advocates for the body-spirit duality and the spiritual superiority over mere physical existence. According to this view, the spirit can either achieve its fulfillment apart from the physical word or guide the latter to its maximum accomplishment. Conversely, the alternative perspective posits that the notion of excellence (...) and its practice can only be conceived and put in motion by living beings in a dynamic relationship among themselves. Implicated in the former is the diminishment of the body in relation to its counterpart and its subsequent mortification and (not rarely) annihilation. Implicated in the latter is the elevation of living beings and the understanding of them being the sole performers of virtuous conduct. (shrink)

Although 43 countries have a monarch as their head of state, the question of whether monarchies can be morally justified has been neglected by contemporary philosophers. In this article, I argue that it is doubtful whether any existing monarchies can be morally justified. As I show, they all suffer from one or more of the following defects: they flout democratic principles; they are non-meritocratic; and/or they fail to provide at least some royals with an adequate range of lifestyle options. However, (...) I go on to identify a novel type of elective monarchy that escapes these problems, and which, I submit, can be vindicated as long as it serves legitimate public objectives (e.g. by promoting social cohesion among citizens and/or by fostering international trade).

The paper uses two historical examples, public health (1840-1880) and town planning (1945-1975) in Britain, to analyse the challenges faced by goal-driven research, an increasingly important trend in science policy, as exemplified by the prominence of calls for addressing Grand Challenges. Two key points are argued. (1) Given that the aim of research addressing social or global problems is to contribute to improving things, this research should include all the steps necessary to bring science and technology to fruition. This need (...) is captured by the idea of practical integration, which brings this type of research under the umbrella of collective practical reason rather than under the aegis of science. Achieving practical integration is difficult for many reasons: the complexity of social needs, the plurality of values at stake, the limitation of our knowledge, the elusive nature of the skills needed to deal with uncertainty, incomplete information and asymmetries of power. Nevertheless, drawing from the lessons of the case studies, it is argued that (2) practical integration needs a proper balance between values, institutions and knowledge: i.e. a combination of mutual support and mutual limitation. Pursuing such a balance provides a flexible strategy for approximating practical integration. (shrink)

According to Mary Midgley, philosophy is like plumbing: like the invisible entrails of an elaborate plumbing system, philosophical ideas respond to basic needs that are fundamental to human life. Melioristic projects in philosophy attempt to fix or reroute this plumbing. An obstacle to melioristic projects is that the sheer familiarity of the underlying philosophical ideas renders the plumbing invisible. Philosophical genealogies aim to overcome this by looking at the origins of our current concepts. We discuss philosophical concepts developed in Indigenous (...) cultures as a source of inspiration for melioristic genealogy. Examining the philosophical concepts of these communities is useful because it gives us a better idea of the range of ethical, political, and metaphysical approaches that exist in the world. Members of western societies do not get a clear view of this range, in part because living in large groups presents its own constraints and challenges, which limit philosophical options. We argue that features of Indigenous philosophies, such as egalitarianism and care for one's natural environment, are not inevitable byproducts of Native material conditions and lifestyles, but that they are deliberate forms of conceptual engineering. We propose that comparative philosophy is an integral part of the genealogical project. -/- . (shrink)
