According to the perceptual-attentional limitations hypothesis, the confusion between expressions of disgust and anger may be due to the difficulty in perceptually distinguishing the two, or insufficient attention to their distinctive cues. The objective of the current study was to test this hypothesis as an explanation for the confusion between expressions of disgust and anger in adults using eye-movements. In Experiment 1, participants were asked to identify each emotion in 96 trials composed of prototypes of anger and prototypes of disgust. (...) In Experiment 2, fixation points oriented participants’ attention toward the eyes, the nose, or the mouth of each prototype. Results revealed that disgust was less accurately recognised than anger (Experiment 1 and 2), especially when the mouth was open (Experiment 1 and 2), and even when attention was oriented toward the distinctive features of disgust (Experiment 2). Additionally, when attention was oriented toward certain zones, the eyes (which contain characteristics of anger) had the longest dwell times, followed by the nose (which contains characteristics of disgust; Experiment 2). Thus, although participants may attend to the distinguishing features of disgust and anger, these may not aid them in accurately recognising each prototype. (shrink)

The unity of aesthetic and teleological judgment, the third and earlier Critiques, is based on Kant′s discovery of a “heuristic method” for applying judgments regarding sense phenomena to abstract thought, a “second attention” which enables an “idea of the whole”. Synthetic judgment, basis for cognition and human action, depends on efficacy of non-empirical insights: the transcendental standpoint, “regulative” ideas, consciousness of “ought” and the reality of freedom, universality of natural mechanism, the principle of “fortuitous” purposiveness. The activity of reflective judgment (...) in the encounter with the beautiful, sublime, living, and two paradigmatic types of explanation, inspired by Spinoza′s distinction of extensio and cogitatio, permit Kant to bridge the gap between freedom and necessity, theoretical knowledge and morality.

Empowerment in healthcare is becoming increasingly popular, including in obstetrics, because of its benefits for both individual health and health promotion. Many authors and organizations, such as the World Health Organization, advocate it as a means of engaging communities in the adoption of health-promoting behaviors and fostering patient-centered care. It aims to enable patients to assert their decisions and choices while respecting their personal values. This desire to respect the uniqueness and autonomy of each individual echoes a number of ethical (...) principles and theories. In this article, the authors aim to answer the question, How can the concept of empowerment in healthcare contribute to bioethics? They argue that it has important links with feminist bioethics, notably the theory of relational autonomy, as well as with the capability theory of economist and philosopher Amartya Sen. (shrink)

The book is about logical analysis of natural language. Since we humans communicate by means of natural language, we need a tool that helps us to understand in a precise manner how the logical and formal mechanisms of natural language work. Moreover, in the age of computers, we need to communicate both with and through computers as well. Transparent Intensional Logic is a tool that is helpful in making our communication and reasoning smooth and precise. It deals with all kinds (...) of linguistic context in a fully compositional and anti-contextual way. (shrink)

This paper examines different kinds of definite descriptions denoting purely contingent, necessary or impossible objects. The discourse about contingent/impossible/necessary objects can be organised in terms of rational questions to ask and answer relative to the modal profile of the entity in question. There are also limits on what it is rational to know about entities with this or that modal profile. We will also examine epistemic modalities; they are the kind of necessity and possibility that is determined by _epistemic_ constraints (...) related to knowledge or rationality. Definite descriptions denote so-called _offices_, roles, or _things to be._ We explicate these α-offices as partial functions from possible worlds to chronologies of objects of type α, where α is mostly the type of individuals. Our starting point is Prior’s distinction between a ‘weak’ and ‘strong’ definite article ‘the’. In both cases, the definite description refers to at most one object; yet, in the case of the weak ‘the’, the referred object can change over time, while in the case of the strong ‘the’, the object referred to by the definite description is the same forever, once the office has been occupied. The main result we present is the way how to obtain a Wh-knowledge about who or what plays a given role presented by a hyper-office, i.e. _procedure_ producing an office. Another no less important result concerns the epistemic necessity of the impossibility of knowing who or what occupies the impossible office presented by a hyper-office. (shrink)

In the following extract, Mondzain examines the way in which the spiritual hegemony of the Early Christian and Byzantine church was transformed into political power. The primary tool used in this endeavor was the icon. The representation of the holy figures of Christianity as space-occupying physical beings puts into play a series of spatial operations which aided in the exercise of temporal, imperial authority.

Back cover: This book develops a philosophical account that reveals the major characteristics that make an explanation in the life sciences reductive and distinguish them from non-reductive explanations. Understanding what reductive explanations are enables one to assess the conditions under which reductive explanations are adequate and thus enhances debates about explanatory reductionism. The account of reductive explanation presented in this book has three major characteristics. First, it emerges from a critical reconstruction of the explanatory practice of the life sciences itself. (...) Second, the account is monistic since it specifies one set of criteria that apply to explanations in the life sciences in general. Finally, the account is ontic in that it traces the reductivity of an explanation back to certain relations that exist between objects in the world (such as part-whole relations and level relations), rather than to the logical relations between sentences. Beginning with a disclosure of the meta-philosophical assumptions that underlie the author’s analysis of reductive explanation, the book leads into the debate about reduction(ism) in the philosophy of biology and continues with a discussion on the two perspectives on explanatory reduction that have been proposed in the philosophy of biology so far. The author scrutinizes how the issue of reduction becomes entangled with explanation and analyzes two concepts, the concept of a biological part and the concept of a level of organization. The results of these five chapters constitute the ground on which the author bases her final chapter, developing her ontic account of reductive explanation. (shrink)

This paper looks at statements I am in a position to make ‘straight off’: observational judgements, perceptual and memory statements, statements about my posture, my intentions, and so on. These kinds of statement pose a problem: what is the nature of my entitlement to them? I focus on observational judgements and on two contrasting approaches to them. The first, which I reject, provides an account of my warrant for them; the second, which I defend, disconnects my entitlement from possession of (...) a justification. I consider what light the second approach sheds on the other kinds of statements I am in a position to make straight off. (shrink)

Both traditional and recent accounts of the beneficial and therapeutic effects of psychedelic experiences tie these effects to specifically epistemic changes, for example the enabling of spiritual or psychological insight, or disruption of problematic beliefs or thought patterns. While these alleged benefits have sometimes been thought to be facilitated by false or even delusional beliefs (e.g. Pollan 2015), recent philosophical discussion strikes a more optimistic tone, arguing that the epistemic risks involved with psychedelic drug use tend to be relatively benign (...) and outweighed by epistemic benefits (Letheby 2021). In this paper, we seek to nuance this picture by drawing attention to the crucial role played by social factors in determining the epistemic effects of psychedelic experiences. We argue that the very openness of mind and heightened sense of clarity and certainty that is often thought to facilitate the epistemic benefits of psychedelic drug use, also make the user more vulnerable to adverse epistemic influence from the social environment, to a degree not acknowledged in the current literature. Examining the epistemic influences of the social environment is thus important for understanding the necessary precautions of informed consent and overall safe drug use. (shrink)

Despite growing interest in emotions, organizational scholars have largely ignored the moral emotion of schadenfreude, which refers to pleasure felt in response to another’s misfortune. As a socially undesirable emotion, it might be assumed that individuals would be hesitant to share their schadenfreude. In two experimental studies involving emotional responses to unethical behaviors, we find evidence to the contrary. Study 1 revealed that subjects experiencing schadenfreude were willing to share their feelings, especially if the misfortune was perceived to be deserved. (...) Study 2 extends this work by incorporating schadenfreude targets of different status. Consistent with the “tall poppy syndrome,” subjects were more willing to share schadenfreude concerning high status targets than low status targets when the perceived severity of the target’s misconduct was low. This status effect disappeared at higher levels of perceived deservingness, however. Reported willingness to share schadenfreude was strongest at these levels but did not differ significantly between high and low status targets. These findings build on the social functional account of emotions, suggesting that sharing schadenfreude may signal normative cues to others regarding workplace behaviors that are deemed to be unethical.

Reshaping our methodological research tools for adequately capturing injustice and domination has been a central aspiration of feminist philosophy and social epistemology in recent years. There has been an increasingly empirical turn in recent feminist and political theorization, engaging with case studies and the challenges arising from conducting research in solidarity with unequal partners. I argue that these challenges cannot be resolved by merely adopting a norm and stance of deference to those in the struggle for justice. To conduct philosophical (...) research in an engaged and solidaristic manner, I suggest that deference be supplemented by three methodological and normative principles: 1) epistemic humility, 2) accountability, and 3) co-producing knowledge. I situate these principles within contemporary philosophical work on solidarity, and show how they might help confront power imbalances and other methodological hazards that arise when conducting research in solidarity with others. I arrive at these principles in part by critically reflecting on my own attempt to conduct research in solidarity with women’s rights activists in Senegal. (shrink)

We argue that relating to myself as me provides, as such, a reason to care about myself: grasping that an event involves me, instead of another, makes it matter in a special way. Further, this self-concern is not simply a matter of seeing in myself some instrumental value for other ends. We use as our foil a recent skeptical challenge to this view offered in Setiya 2015. We think the case against self-concern is powered by unwarrantedly narrow construals of three (...) key notions. One is the notion of a first-personal way of relating to oneself. A narrow account of the first person in terms of special epistemic relations to oneself makes it easy to overlook a source of non-instrumental reasons of self-concern, located in the special relation a subject has to herself as agent. Two is the notion of what it is to be a reason. And, three, is the notion of self-concern itself. We show that the skeptical case rests in part on a slide towards neighbouring but distinct notions of egoism and selfishness. We also argue that Setiya’s notion of self-love, offered to capture the pre-theoretical intuition of self-concern, cannot do it justice. (shrink)

This paper analyzes what it means for philosophy of science to be normative. It argues that normativity is a multifaceted phenomenon rather than a general feature that a philosophical theory either has or lacks. It analyzes the normativity of philosophy of science by articulating three ways in which a philosophical theory can be normative. Methodological normativity arises from normative assumptions that philosophers make when they select, interpret, evaluate, and mutually adjust relevant empirical information, on which they base their philosophical theories. (...) Object normativity emerges from the fact that the object of philosophical theorizing can itself be normative, such as when philosophers discuss epistemic norms in science. Metanormativity arises from the kind of claims that a philosophical theory contains, such as normative claims about science as it should be. Distinguishing these three kinds of normativity gives rise to a nuanced and illuminating view of how philosophy of science can be normative. (shrink)

There is already a long history of conversation between feminism and deconstruction, feminist theorists and Derrida or Derrideans. That conversation has been by turns fraught and constructive. While some of these interactions have occurred in queer feminism, to date little has been done to stage an engagement between deconstruction and transfeminism. Naysayers might think that transfeminism is too recent and too identitarian a discourse to meaningfully interact with Derrida’s legacy. On the other hand, perhaps Derrida’s work was too embedded in (...) second wave feminism, and in some cases implicit misogyny and transphobia, to meet transfeminism on its own playing field. And yet, I think both suspicions shortchange these discourses. In this article, I stage a conversation between Derrida and two writers working in the area of trans feminism: Paisley Currah and Julia Serano. I explore, in particular, how their conceptions of gender neutrality or gender pluralism are complementary and together change the so-called “question of woman,” from a philosophical and political perspective.

Descartes claims that the passions of the soul are “all in their nature good” even though they exaggerate the value of their objects, have the potential to deceive us, and often mislead us. What, then, can he mean by this? In this paper, I argue that these effects of the passions are only problematic when we incorrectly take their goodness to consist in their informing us of harms and benefits to the mind-body composite. Instead, the passions are good in their (...) motivational function, which they carry out by representing objects and situations as having various properties and thereby appearing to be “reasons of goodness.” Further, I argue that the main way in which the passions are problematic is merely an occasional physiological byproduct of a well- functioning system. I show, therefore, that the passions’ motivational function, representationality, and accompanying physiology are all significant and interrelated aspects of their goodness. (shrink)

This paper focuses on the centrality of permaculture design courses as the principal sociopolitical strategy of the permaculture community in Canada to transform local food production practices. Building on the work of Antonio Gramsci and political agroecology as a framework of analysis, we argue that permaculture instruction remains deeply embedded within market and colonial relations, which orients the pedagogy of permaculture trainings in such a way as to reproduce the basic elements of the colonial capitalist economy among its practitioners. In (...) the specific case of eastern Ontario, this embeddedness had the effect of diluting the transformative capacity of permaculture practitioners who were unable to create its own social movement organization. The paper then highlights key elements of the agroecological pedagogy used by the Brazilian Landless Rural Workers Movement and the Escola Latinoamericana de Agroecología in Paraná, Brazil. The objective is to draw lessons from these inspiring experiences, in a rather unique context of struggles that can help to critically assess the pedagogical practices and principles presently informing permaculture communities in Canada and in advanced industrialized countries more generally. We then conclude by reiterating the key arguments and lessons drawn from the Brazilian pedagogical experiences, pointing out the importance of engagement and coalition-building with established rural and urban movements, as well as progressive farmer, Indigenous, and rural associations to foster a just and sustainable transformation of agri-food systems, starting at the local and regional levels. It also emphasizes the need for the most marginalized sectors to lead the way towards an agroecological transition. (shrink)

In lieu of an abstract, here is a brief excerpt of the content:Hume on Human Excellence Marie A. Martin Hume was, in important respects, still verymuch a part ofthe classical ethical tradition. This is something we tend to overlook because we come out of a distinctly modern moral tradition, and we normally approach Hume looking for answers to a set of questions that are distinct, and often far removed, from the central questions of the classical tradition. Yet, the classical (...) aspects of Hume's ethics are not irrelevant to contemporary moral debates. There is evidence in recent years of a growing discontent with all the permutations of the two dominant strands of contemporary moral thought, Kantianism and utilitarianism. The sort of radical critique found in the works of Maclntyre, the increasing popularity of communitarian theories, and the resurgence of interest in virtue ethics in general, and Aristotelianism in particular, are all indications of this discontent. What I wish to suggest is that Hume's moral thought might prove a rich source for those who are dissatisfied with the direction ofmodern moral theory, and especially for those who believe that there is something within the classical tradition of virtue ethics worth salvaging. For Hume is a virtue ethicist, albeit one in modern dress, who, poised between the ancients and moderns, self-consciously chose to align himself with the ancient tradition, asserting its superiority over the modern. The ancient moralists are, Hume claims, the "best models,"1 morals being the one science "inwhich theyare not surpassed by the moderns" (E 330). The aim of this paper is to take an initial step towards refocusing our view on the largely neglected classical aspects of Hume's moral thought. The relationship between Hume's moral thought and the classical tradition is both extensive and complex, and I do not pretend to do anything more in this paper than present the tip of the iceberg. But the tip I shall examine is central to all that lies below; it is Hume's conception ofhuman excellence. Virtue or Human Excellence Perhaps Hume's most complete description ofhuman excellence occurs in the conclusion ofAn Enquiry Concerning the Principles ofMorals. Hume presents us with the fictional character, Cleanthes, as one whom "a philosopher might select... as a model ofperfect virtue" (E 270). He is, Hume claims, "a man ofhonour andhumanity," one ofwhom "[e]very one, who has anyintercourse... is sure offair and kind treatment." His Volume XVIII Number 2 383 MARIE A. MARTIN "assiduous application... [and] quick penetration... prognosticate the greatest honours and advancement." His company is enjoyed by all because he has "so much wit with good manners; so much gallantry without affectation" and "so much ingenious knowledge." His "cheerfulness... runs through the whole tenor ofhislife, and preserves a perpetual serenity on his countenance, and tranquillity ofhis soul." Finally, "[h]e has met with severe trials, misfortunes as well as dangers; and by his greatness ofmind, was still superior to all ofthem" (E 269-70). In the Treatise, Hume offers a less specific, yet similar portrait of human excellence: when we enumerate the good qualities of any person, we always mention those parts ofhis character, which renderhim a safe companion, an easy friend, a gentle master, an agreeable husband, or an indulgent father. We consider him with all hisrelations in society; andlove orhate him, according as he affects those, who have any immediate intercourse with him. And 'tis a most certain rule, that if there be no relation oflife, in which I cou'd not wish to stand to aparticular person, his character must so far be allow'd to be perfect. If he be as little wanting to himselfas to others, his character is entirely perfect.2 Although there are numerous passages throughout Hume's works that paint the same general picture, I will offer only one more, his description of an ideally virtuous disposition from his essay, The Sceptic: that which leads to action and employment, renders us sensible to the social passions, steels the heart against the assaults offortune, reduces the affections to ajustmoderation, makes our own thoughts an entertainment to us, and inclines us rather to the pleasure of society and conversation, than to those ofthe senses.3 What is common to all these descriptions...

This paper deals with two issues. First, it identifies structured propositions with logical procedures. Second, it considers various rigorous definitions of the granularity of procedures, hence also of structured propositions, and comes out in favour of one of them. As for the first point, structured propositions are explicated as algorithmically structured procedures. I show that these procedures are structured wholes that are assigned to expressions as their meanings, and their constituents are sub-procedures occurring in executed mode. Moreover, procedures are not (...) mere aggregates of their parts; rather, procedural constituents mutually interact. As for the second point, there is no universal criterion of the structural isomorphism of meanings, hence of co-hyperintensionality, hence of synonymy for every kind of language. The positive result I present is an ordered set of rigorously defined criteria of fine-grained individuation in terms of the structure of procedures. Hence procedural semantics provides a solution to the problem of the granularity of co-hyperintensionality. (shrink)

Measuring the rate at which the universe expands at a given time–the ‘Hubble constant’– has been a topic of controversy since the first measure of its expansion by Edwin Hubble in the 1920s. As early as the 1970s, Sandage and de Vaucouleurs have been arguing about the adequate methodology for such a measurement. Should astronomers focus only on their best indicators, e.g., the Cepheids, and improve the precision of this measurement based on a unique object to the best possible? Or (...) should they “spread the risks”, i.e., multiply the indicators and methodologies before averaging over their results? Is a robust agreement across several uncertain measures, as is currently argued to defend the existence of a ‘Hubble crisis’ more telling than a single 1% precision measurement? This controversy, I argue, stems from a misconception of what managing the uncertainties associated with such experimental measurements require. Astrophysical measurements, such as the measure of the Hubble constant, require a methodology that permits both to reduce the known uncertainties and to track the unknown unknowns. Based on the lessons drawn from the so-called Hubble crisis, I sketch a methodological guide for identifying, quantifying and reducing uncertainties in astrophysical measurements, hoping that such a guide can not only help to re-frame the current Hubble tension, but serve as a starting point for future fruitful discussions between astrophysicists, astronomers and philosophers.

The concept of community of persons, which focuses on both persons and the whole, helps understand solidarity. The latter is based on the social nature of persons. Community of persons and solidarity seems to be able to move away from the individualist perspective or the individualism-collectivism dichotomy. Using autopraxeography in a pragmatic constructivism epistemological paradigm, this article aims to explore how organizations can develop solidarity in a workplace. The experience presented takes place in a bank. It shows that communities of (...) persons with employees and customers are both ethical and financially efficient. These communities build a dialogue between persons and organizations. Nevertheless, it is impossible to force solidarity because it could generate derision that is contrary to the wished goal. Finally, while this model is based on solidarity, it focuses solely on internal solidarity. (shrink)

I examine the views of the renowned Catholic environmentalist, Thomas Berry, C.P., by comparing them with those of Thomas Aquinas, an author Berry frequently references. I intend to show that while the two share a number of views in common, ultimately the two diverge on many foundational issues, resulting in differing conclusions as to how we should regard and treat the environment. Aquinas upholds divine transcendence, whereas Berry regards the notion of divine transcendence to lead to the exploitation of creation (...) and locates the divine in the universe itself. Berry accordingly thinks that we should revere all natural things, whereas Aquinas thinks we should revere God and creatures in God’s image. Aquinas maintains that the human soul is created by God and is in God’s image. He sees our rational soul as placing us above other natural things, and from it follows our responsibility to care for nature. Berry, to the contrary, sees this affirmation of discontinuity between humans and the rest of nature to be the root of our environmental woes, as providing a justification for human exploitation of nature. For Berry, humans have no special status, but are one member alongside others in the earth community. Rather than being created by God, “humans have nothing but what they receive from the universe.” By highlighting both the similarities and differences between these authors, I hope to contribute to the project of formulating a sound environmental ethics.

Medical explanations have often been thought on the model of biological ones and are frequently defined as mechanistic explanations of a biological dysfunction. In this paper, I argue that topological explanations, which have been described in ecology or in cognitive sciences, can also be found in medicine and I discuss the relationships between mechanistic and topological explanations in medicine, through the example of network medicine and medical genetics. Network medicine is a recent discipline that relies on the analysis of various (...) disease networks in order to find organizing principles in disease explanation. My aim is to show how topological explanations in network medicine can help solving the conceptual issues that pure mechanistic explanations of the genetics of disease are currently facing, namely the crisis of the concept of genetic disease, the progressive geneticization of diseases and the dissolution of the distinction between monogenic and polygenic diseases. However, I will also argue that topological explanations should not be considered as independent and radically different from mechanistic explanations for at least two reasons. First, in network medicine, topological explanations depend on and use mechanistic information. Second, they leave out some missing gaps in disease explanation that require, in turn, the development of new mechanistic explanations. Finally, I will insist on the specific contribution of topological explanations in medicine: they push us to develop an explanation of disease in general, instead of focusing on single explanations of individual diseases. This last point may have major consequences for biomedical research. (shrink)

Personhood is ascribed on others, such that someone who is recognized to be a person is bestowed with certain civil rights and the right to decision making. A rising question is how severely brain-injured patients who regain consciousness can also regain their personhood. The case of patients with locked-in syndrome is illustrative in this matter. Upon restoration of consciousness, patients with LIS find themselves in a state of profound demolition of their bodily functions. From the third-person perspective, it can be (...) expected that LIS patients might experience a differential personal identity and may lose their status as persons. However, from the patients’ perspective, it is uncontested that they retain their personal identity and that they consider themselves to be persons. We here include results from a survey with patients with LIS aimed at identifying the primary expectations of patients for their care by non-medical professionals. Based on these first-hand reports, we argue that personhood in LIS is progressively regained as the widening circle of others recognizes them as persons. (shrink)

Although logical empiricism is now mostly decried, their naturalist claim that the content of a theory can be read off from its structure, without any philosophical considerations needed, still supports traditional strategies to escape cases of underdetermination. The appeal to theoretical equivalence or to theoretical virtues, for instance, both assume that there is a neutral standpoint from which the structure of the theories can be analyzed, the physically relevant from the superfluous separated, and a comparison made between their theoretical content (...) and virtues. In my dissertation, I examine the presuppositions upon which such strategies depend. I argue that the methodological principle underlying them, according to which theories with no superfluous structure should be preferred, is unpractical, for what constitutes relevant structure is determined by epistemic considerations about the aim of scientific theories. In chapter 1, I analyze the claim that theories with ordinary bosons and fermions are theoretically equivalent to theories with exotic `paraparticles'. I argue that this claim does not do justice to the latter, as the proof is formulated in a vocabulary parochial to the former and thus favors one of the theory while giving an impoverished version of the second. In chapter 2, I examine recent arguments to the effects that any interpretation of Quantum Mechanics that can offer a no-go theorem against paraparticles possesses an explanatory advantage over other interpretations and should, as such, be favored over others. Given that most physicists consider paraparticles as surplus structure whose non-observation does not require an explanation, I evaluate arguments of both sides and suggest a third way to approach the question. Finally, in chapter 3, I turn my attention to methods for excluding another kind of unphysical structure, mathematical artifacts, from rival dark matter models. Simulations are our only window into what rival models predict about the universe’s structure. But for them to play a useful role in generating knowledge, we need to distinguish reliably between real predictions and artifacts. I argue that robustness analysis fails to fulfill this task. I propose in its place another methodology, that of crucial simulations. (shrink)
