This paper mainly addresses the relation between essentialism and philosophical method. In particular, our analysis centers on the anti-essentialist argument that proposed, given its essentialist bonds, the abandonment of the notion of method. To this end, we make use of the empirical evidence concerning essentialism provided by psychological research, which has shown that our proneness to essentialize is not a by-product of our social and cultural practices as some anti-essentialists have thought. Rather, it is a deeply rooted cognitive tendency that (...) plays a major role in concept formation and so in our understanding of things. Thus, given that such inclination toward essentialism is certain to happen, we argue for a conception of method that, while not overcoming such tendency, avoids the presumed disastrous consequences feared by most anti-essentialists.

In this paper it is explored the relationship between the practice of philosophy and the development of a sort of professional intuition through it. That is to say, this paper is broadly concerned with a very traditional metaphilosophical topic, namely, the sort of abilities a skillful philosopher must possess to excel at philosophizing. More precisely, it critically examines the long-held common place in philosophy according to which the competences acquired through philosophical training are related to applying concepts. Such a view (...) has given way to the idea that philosophers gain expert intuitions -provided by philosophical training- about using concepts. In this sense, it has been shown in experimental philosophy that philosophers holding this notion of the practice of philosophy might be under the illusion of expertise. For these reasons, we argue, based on the work of the psychologist Deanna Kuhn, that philosophical expertise, on a more positive account, might be related to the evaluation, construction, and rebuttal of arguments. With this in mind, we also explore the relationship between intuition and arguments in philosophy. (shrink)

The main objective of this paper is to address the problem of the philosophical method, which consists of the lack of consensus among philosophers regarding the proper procedure to carry out this human activity. In this sense, it examines a few methodological proposals put forward by some representatives of contemporary philosophy, emphasizing the impact that the development of modern science has had on such views. In addition, the plausibility of such proposals is assessed.

Este trabajo tiene como objetivo examinar críticamente la discusión en torno a la identidad nacional panameña denominado el problema de lo panameño, particularmente aquellas perspectivas propuestas por filósofos profesionales, así como determinar su alcance y revisitar sus presupuestos. Con ello en mente, intentaremos contextualizar hasta donde sea posible dicha discusión, buscando poner de relieve los factores históricos que la motivan, además de evaluar la vigencia de esta.

Howard’s moral fortification theory of criminal punishment lends itself to justifying correction for children in schools that is supportive. There are good reasons to include other students in the learning opportunity occasioned by doing right in response to wrong, which need not exploit the wrongdoing student as a mere means. Care ethics can facilitate restorative and problem-solving approaches to correction. However, there are overriding reasons against doing so when this stigmatises the wrongdoing student, since this inhibits their learning. Responses that (...) avoidably stigmatise students impermissibly undermine both the developmental ethos of education, and students’ recognition and respect for each other as equals. (shrink)

Este trabajo tiene como objetivo principal examinar y determinar las consecuencias de las metáforas contenidas en las obras de Diego Domínguez Caballero, fundador de la filosofía académica panameña. Tales metáforas se volvieron fundamentales para el desarrollo discursivo de la filosofía panameña y también para las ciencias sociales en el país, como la historia y la sociología. Con este fin, recurriremos a la teoría de las metáforas conceptuales desarrollada por Lakoff y otros como una herramienta de ayuda para analizar las que (...) Domínguez emplea. Del mismo modo, intentamos dar cuenta de la larga incidencia discursiva de dichas metáforas a la luz de los resultados de la investigación psicológica sobre el esencialismo. -/- The main objective of this work is to examine and determine the consequences of the metaphors contained in the works of Diego Domínguez Caballero, founder of Panamanian academic philosophy. Such metaphors became fundamental for the discursive development of Panamanian philosophy and also for the social sciences in this country, as history and sociology. To this end, we will turn to the theory of conceptual metaphors developed by Lakoff and others as a helpful tool in analyzing the ones used by Domínguez. In the same way, we try to account for the long discursive incidence of these metaphors in the light of the results of psychological research on essentialism. (shrink)

This chapter considers the ways in which whiteness as a skin color and ideology becomes a dominant level that sets the background against which all things, people and relations appear. Drawing on Merleau-Ponty's phenomenology, it takes up a series of films by Bruce Nauman and Marlon Riggs to consider ways in which this level is phenomenally challenged providing insights into the embodiment of racialization.

The paper considers whether psychiatric kinds can be natural kinds and concludes that they can. This depends, however, on a particular conception of ‘natural kind’. We briefly describe and reject two standard accounts – what we call the ‘stipulative account’ (according to which apparently a priori criteria, such as the possession of intrinsic essences, are laid down for natural kindhood) and the ‘Kripkean account’ (according to which the natural kinds are just those kinds that obey Kripkean semantics). We then rehearse (...) a more permissive account: Richard Boyd’s ‘homeostatic property cluster’ (HPC) account. We argue that psychiatric kinds can in principle count as natural kinds on the HPC account. Moreover, specific psychiatric kinds (Tourette’s, schizophrenia, etc.) can be natural kinds even if the category psychiatric disorder is not itself a natural kind. (shrink)

Imagine you find yourself in heaven after death, only to discover that the soul of your dearest love is suffering in hell. Would your bliss be marred by the suffering of your loved one? The “argument from love” challenges the traditional Christian conception of heaven and hell as places of perfect bliss and terrible suffering, respectively, on the grounds that no lover in heaven could be very happy if she were aware that her beloved was suffering in hell. Love requires (...) concern for the well-being of one’s beloved, thus apparently rendering heavenly bliss impossible for those who love an unreformed sinner. Here I defend a traditional conception of heaven and hell against the perplexing mismatch between the blessed souls’ love for the damned and apparent indifference to their plight. (shrink)

Emotion processing is known to be impaired in psychopathy, but less is known about the cognitive mechanisms that drive this. Our study examined experiencing and suppression of emotion processing in psychopathy. Participants, violent offenders with varying levels of psychopathy, viewed positive and negative images under conditions of passive viewing, experiencing and suppressing. Higher scoring psychopathics were more cardiovascularly responsive when processing negative information than positive, possibly reflecting an anomalously rewarding aspect of processing normally unpleasant material. When required to experience emotional (...) response, by ‘getting into the feeling’ of the emotion conveyed by a negative image, higher factor 1 psychopathic individuals showed reduced responsiveness, suggesting that they were less able to do this. These data, together with the absence of corresponding differences in subjective self-report might be used to inform clinical strategies for normalising emotion processing in psychopathic offenders to improve treatment outcome, and reduce risk amongst this client group.

La Divine Comédie est le récit poétique d'une vision, d'une expérience surnaturelle qui se fait toujours plus intense, et que le langage peine toujours davantage à traduire. La mission de Dante consiste à rapporter cette vision. La question que nous pose la Divine Comédie réside dans la différence entre l'intraduisible et l'indicible: y a-t-il un intraduisible dicible? Ou en d'autres termes : quelle est, au-delà du topos de l'indicible poétique, et au-delà de la figure rhétorique de la prétérition, la signification (...) conceptuelle de l'expression du "dire" dans la Divine Comédie?

This paper is an attempt to approach Stanley Fish’s anti-foundationalist argument whose clear formulation is found in the development of his literary theory. For this reason, we will start by, first, introducing Fish's literary theory, and, second, it is explored some aspects of Fish’s theories and their bonds with anti-foundationalism.

L’histoire de la pensée sémiotique se caractérise par une oscillation entre définition large et définition étroite de son objet. Au Moyen Âge, la définition augustinienne du signe est jugée trop étroite, car elle ne concerne que le signe sensible. De nouvelles définitions tentent alors de faire des concepts des signes qui renvoient aux choses. L’Âge moderne, au contraire, affirme une volonté de rétrécissement à l’égard de la notion de signe. Cet article montrera les caractéristiques d’une telle réflexion sémiotique à travers (...) deux auteurs représentatifs d’un premier empirisme moderne : Pierre Gassendi et Thomas Hobbes. Le retour à une sémiotique étroite s’effectue par la référence aux traditions stoïcienne, sceptique et épicurienne, ainsi qu’à un Aristote renouvelé, et par une prédilection affichée pour la valeur indiciaire du signe par rapport à sa valeur sémantique. Ceci veut dire que les empiristes vont insister avant tout sur la fonction remémorative du signe et sur sa valeur de probabilité. L’indice en tant que trace sera ainsi privilégié par rapport au signe communicationnel, et il s’agira d’en défendre la validité en tant qu’il s’inscrit dans une échelle de certitude, au sommet de laquelle se situe la preuve.

En tal sentido, defenderemos la idea de que las ideas de Nietzsche relacionadas a la crueldad tienen que entenderse como parte de un mensaje general de aceptación de (...) las limitaciones humanas, para dar paso a nuevos tipos de seres humanos.

Epistemic peer disagreement raises interesting questions, both in epistemology and in philosophy of science. When is it reasonable to defer to the opinion of others, and when should we hold fast to our original beliefs? What can we learn from the fact that an epistemic peer disagrees with us? A question that has received relatively little attention in these debates is the value of epistemic peer disagreement—can it help us to further epistemic goals, and, if so, how? We investigate this (...) through a recent case in paleoanthropology: the debate on the taxonomic status of Homo floresiensis remains unresolved, with some authors arguing the fossils represent a novel hominin species, and others claiming that they are Homo sapiens with congenital growth disorders. Our examination of this case in the recent history of science provides insights into the value of peer disagreement, indicating that it is especially valuable if one does not straightaway defer to a peer’s conclusions, but nevertheless remains open to a peer’s evidence and arguments.

This paper presents a dilemma which it has been alleged by Kim Frost must be faced by any defender of the notion of a two-way power and offers a solution to the dilemma which is distinct from Frost’s own. The dilemma is as follows: assuming that powers are to be individuated by what they are powers to do or undergo, then either there is a unified description of the manifestation-type which individuates the power, or there is not. If there is, (...) then two-way powers are revealed really to be one-way powers, after all. If there is not, then it is difficult to explain why the two-way power does not simply dissolve into a mere combination of two one-way powers. The paper offers an account of what a two-way power is that is distinct from the one Frost takes for granted, and argues that this different conception is the key to avoiding the dilemma. It is also argued that this alternative conception has several further advantages over its rival and also that it has no less of a claim than Frost’s notion to be prefigured in Aristotle’s original discussion.

Scepticism concerning the idea of causation being linked to contingent chance-raising is articulated in Beebee’s challenging chapter. She suggests that none of these approaches will avoid the consequence that spraying defoliant on a weed is a cause of the weed’s subsequent health. We will always be able to abstract away enough of the healthy plant processes so all that’s left is the causal chain involving defoliation and health. In those circumstances, there will be contingent chance-raising. Beebee’s conclusion is that we (...) should reject the idea of contingent chance-raising and just accept that all causation involves chance-raising. This involves the reclassification of some intuitive cases of causation as causal processes without causation but rather hindering (a distinctive kind of process). It seems clear from this discussion and from the brief earlier remarks about the status of prevention that the classification of types of causal processes and the characterization of their link to causation are matters of some importance.

In this paper Beebee argues that the problem of induction, which she describes as a genuine sceptical problem, is the same for Humeans than for Necessitarians. Neither scientific essentialists nor Armstrong can solve the problem of induction by appealing to IBE, for both arguments take an illicit inductive step.

This paper argues that public statues of persons typically express a positive evaluative attitude towards the subject. It also argues that states have duties to repudiate their own historical wrongdoing, and to condemn other people’s serious wrongdoing. Both duties are incompatible with retaining public statues of people who perpetrated serious rights violations. Hence, a person’s being a serious rights violator is a sufficient condition for a state’s having a duty to remove a public statue of that person. I argue that (...) this applies no less in the case of the ‘morally ambiguous’ wrongdoer, who both accomplishes significant goods and perpetrates serious rights violations. The duty to remove a statue is a defeasible duty: like most duties, it can be defeated by lesser-evil considerations. If removing a statue would, for example, spark a violent riot that would risk unjust harm to lots of people, the duty to remove could be outweighed by the duty not to foreseeably cause unjust harm. This would provide a lesser-evil justification for keeping the statue. But it matters that the duty to remove is outweighed, rather than negated, by these consequences. Unlike when a duty is negated, one still owes something in cases of outweighing. And it especially matters that it is outweighed by the predicted consequences of wrongful behaviour by others.

In this paper, I explore the question what a continuant is, in the context of a very interesting suggestion recently made by Rowland Stout, as part of his attempt to develop a coherent ontology of processes. Stout claims that a continuant is best thought of as something that primarily has its properties at times, rather than atemporally—and that on this construal, processes should count as continuants. While accepting that Stout is onto something here, I reject his suggestion that we should (...) accept that processes are both occurrents and continuants; nothing, I argue, can truly occur or happen, which does not have temporal parts. I make an alternative suggestion as to how one might deal with the peculiar status of processes without jettisoning a very natural account of occurrence; and assess the consequences for the category of continuant.

In her ‘Causality and Determination’, Anscombe argues for the strong thesis that despite centuries of philosophical assumption to the contrary, the supposition that causality and necessity have something essential to do with one another is baseless. In this paper, I assess Anscombe’s arguments and endorse her conclusion. I then attempt to argue that her arguments remain highly relevant today, despite the fact that most popular general views of causation today are firmly probabilistic in orientation and thus show no trace of (...) the assumptions Anscombe hoped to undermine. My suggestion is that Anscombe's interests in causality are distinct from those which mostly animate the modern debate about the general nature of causality and that in those specialized areas of philosophy in which those concerns still dominate, one can still see the effects of the fallacies and confusions to which she alerts us. I conclude by offering two possible complementary explanations of the tendency to suppose that causation is a variety of necessitation. (shrink)

Humean compatibilism is the combination of a Humean position on laws of nature and the thesis that free will is compatible with determinism. This article's aim is to situate Humean compatibilism in the current debate among libertarians, traditional compatibilists, and semicompatibilists about free will. We argue that a Humean about laws can hold that there is a sense in which the laws of nature are 'up to us' and hence that the leading style of argument for incompatibilism?the consequence argument?has a (...) false premiss. We also display some striking similarities between Humean compatibilism and libertarianism, an incompatibilist view. For example, standard libertarians face a problem about luck, and we show that Humean compatibilists face a very similar problem. (shrink)

This paper argues, by attention to the category of sub-intentional agency, that many conceptions of the nature of agency are 'over-mentalised', in that they insist that an action proper must be produced by something like an intention or a reason or a desire. Sub-intentional actions provide counterexamples to such conceptions. Instead, it is argued, we should turn to the concept of a two-way power in order to home in on the essential characteristics of actions.

In recent years, calls have been made to address the relative dearth of qualitative sociological investigation into the sensory dimensions of embodiment, including within physical cultures. This article contributes to a small, innovative and developing literature utilizing sociological phenomenology to examine sensuous embodiment. Drawing upon data from three research projects, here we explore some of the ‘sensuousities’ of ‘intense embodiment’ experiences as a distance-running-woman and a boxing-woman, respectively. Our analysis addresses the relatively unexplored haptic senses, particularly the ‘touch’ of heat. (...) Heat has been argued to constitute a specific sensory mode, a trans-boundary sense. Our findings suggest that ‘lived’ heat, in our own physical-cultural experiences, has highly proprioceptive elements and is experienced as both a form of touch and as a distinct perceptual mode, dependent upon context. Our analysis coheres around two key themes that emerged as salient: (1) warming up, and (2) thermoregulation, which in lived experience were encountered as strongly interwoven. (shrink)

This paper considers the analogies and disanalogies between a certain sort of argument designed to oppose scepticism about free will and a certain sort of argument designed to oppose scepticism about the external world. In the case of free will, I offer the ancient Lazy Argument and an argument of my own, which I call the Agency Argument, as examples of the relevant genre; and in the case of the external world, I consider Moore’s alleged proof of an external world. (...) I draw attention to analogies and disanalogies between the arguments offered in each case in order to suggest that although the Agency Argument shares with its Moorean relative the unfortunate property of being dialectically ineffective against some of those it is mainly hoping to convince, it will not be dialectically ineffective against all of them. It is also argued that the Agency Argument is less vulnerable than Moore’s proof to worries about its justificatory structure. (shrink)

According to ‘regularity theories’ of causation, the obtaining of causal relations depends on no more than the obtaining of certain kinds of regularity. Regularity theorists are thus anti-realists about necessary connections in nature. Regularity theories of one form or another have constituted the dominant view in analytic Philosophy for a long time, but have recently come in for some robust criticism, notably from Galen Strawson. Strawson’s criticisms are natural criticisms to make, but have not so far provoked much response from (...) regularity theorists. The paper considers and rebuts Strawson’s objections. For example, Strawson claims that if there were no necessary connections in nature, we ought continually to find the regularity of the Universe surprising. I argue that the fact that the Universe is regular is something we take ourselves (fallibly) to know, and hence, in the light of this knowledge, its continued orderliness is not at all surprising. -/- .

As the author of A Metaphysics for Freedom (Oxford: Oxford University Press, 2012), I respond to each of the preceding eight papers in this Special Issue.

Sex determines much about one's life, but what determines one's sex? The answer is complicated and incomplete: on close examination, ordinary notions of female and male are vague. In 2012, the International Olympic Committee further specified what they mean by woman in response to questions about who, exactly, is eligible to compete in women's Olympic events. I argue, first, that their stipulation is evidence that the use of vague terms is better described by semantic approaches to vagueness than by epistemic (...) approaches. In addition, the IOC's 2012 stipulation was made with sensitivity to its practical consequences. Linguistic actions often have morally relevant consequences, and I contend that, other things equal, we should adopt theories about language that acknowledge the responsibility we bear for what we say. Taking vagueness to be an epistemic phenomenon precludes the sense of agency needed for moral responsibility; taking it to be semantic does not. Thus I advance two arguments for semantic approaches to vagueness, as against epistemic approaches: one descriptive and one normative. (shrink)

Biological sex should be “acknowledged” and “accepted”—but which responses to gender dysphoria might this preclude? Trans-identified people may factually acknowledge their biological sex and regard transition as purely palliative. While generally some level of self-deception and even a high level of nonlying deception of others are sometimes justified, biological sex is important, and there is a nontrivial onus against even palliative, nonsexually motivated cross-dressing. The onus is higher against co-opting the body, even in a minor and/or reversible way, to make (...) a false communication concerning one’s sex. Hardest to defend is the destruction of sexual–reproductive functions and causally downstream functions such as lactation: due to the transcendent nature of sexual–reproductive functions, an appeal to the “principle of totality” here is misplaced. This is not to say that social, and milder medical, transition is absolutely excluded even for severe unmanageable dysphoria, nor that subsequent to any transition, detransition is necessarily required.

The chapter explores whether, or to what extent, recent work in experimental philosophy puts pressure on the idea that the concept of causation is ‘egalitarian’. Causal selection – where experimental subjects tend to rate the causal strength of (for example) a norm-violator more strongly than a non-norm-violator – is a well established phenomenon, and is in prima facie tension with an egalitarian conception of causation; it also, indirectly, puts prima facie pressure on the idea that causation is a worldly phenomenon (...) whose obtaining is independent of facts about norms. The chapter explores both the various psychological mechanisms and the broadly pragmatic approaches to explaining causal selection. It argues that the answer to the question whether or not the concept of causation is egalitarian is currently significantly empirically underdetermined, and suggests some avenues for further investigation.

Many criminal offenders come from disadvantaged backgrounds, which punishment entrenches. Criminal culpability explains some disadvantageous treatment in state-offender interactions; yet offenders remain people, and ‘some mother’s child’, in Eva Kittay’s terms. Offending behaviour neither erases needs, nor fully excuses our responsibility for offenders’ needs. Caring is demanded in principle, recognising the offender’s personhood. Supporting offenders may amplify welfare resources: equipping offenders to provide self-care; to meet caring responsibilities; and enabling offenders’ contribution to shared social life, by providing support and furthering (...) the choices of others seeking to engage with them. The desistance paradigm (viewing desistance from offending as a process, following from an offender’s active choice in the context of stabilising social structures and personal circumstances), implies that a supportive environment may facilitate reduced recidivism. While decisions about criminal culpability need justice, we may use state resources most effectively by also including care ethics in our thinking about punishment. (shrink)

Some bemoan the incivility of our times, while others complain that people have grown too quick to take offense. There is widespread disagreement about what counts as an insult and when it is appropriate to feel insulted. Here I propose a definition and a preliminary taxonomy of insults. Namely, I define insults as expressions of a lack of due regard. And I categorize insults by whether they are intended or unintended, acts or omissions, and whether they cause offense or not. (...) Unintended insults are of particular concern since greater understanding may help us to avoid them. And insults by omission warrant special consideration because they suggest an interesting extension of Grice’s theory of conversational implicature. (shrink)

The voices of children and young people have been largely neglected in discussions of the extent to which the internet takes into account their needs and concerns. This paper aims to highlight young people’s lived experiences of being online.

According to common-sense morality, agents can become morally connected to the wrongdoing of others, such that they incur special obligations to prevent or rectify the wrongs committed by the primary wrongdoer. We argue that, under certain conditions, voluntary and unjustified observation of another agent’s degrading wrongdoing, or of the ‘product’ of their wrongdoing, can render an agent morally liable to bear costs for the sake of the victim of the primary wrong. We develop our account with particular reference to widespread (...) modern phenomena such as so-called ‘revenge porn’, ‘up-skirting’, and the online observation of sexual assault and murder. On our account, observation is not a sui generis basis of liability. Instead, observation grounds liability in virtue of manifesting three, more general, grounds of liability. First, observation can compound a primary wrong, making that wrong more harmful for the victim. Second, observation can constitute degrading treatment of the victim. Third, in certain cases observation can enable primary wrongdoing. We conclude by discussing the conditions under which observing degrading wrongs might be morally justified. (shrink)

The term “value of life” can refer to life’s intrinsic dignity: something nonincremental and time-unaffected in contrast to the fluctuating, incremental “value” of our lives, as they are longer or shorter and more or less flourishing. Human beings are equal in their basic moral importance: the moral indignities we condemn in the treatment of e.g. those with dementia reflect the ongoing human dignity that is being violated. Indignities licensed by the person in advance remain indignities, as when people might volunteer (...) their living, unconscious bodies for surrogacy or training in amputation techniques. Respect for someone’s dignity is significantly impacted by a failure to value that person’s very existence, whatever genuine respect and good will is shown by wanting the person’s life to go well. Valuing and respecting life is not, however, vitalism: there can be good and compelling reasons for eschewing some means of prolonging life. (shrink)

Ideomotor actions are behaviours that are unconsciously initiated and express a thought rather than a response to a sensory stimulus. The question examined here is whether ideomotor actions can also express nonconscious knowledge. We investigated this via the use of implicit long-term semantic memory, which is not available to conscious recall. We compared accuracy of answers to yes/no questions using both volitional report and ideomotor response . Results show that when participants believed they knew the answer, responses in the two (...) modalities were similar. But when they believed they were guessing, accuracy was at chance for volitional report , but significantly higher for Ouija response . These results indicate that implicit semantic memory can be expressed through ideomotor actions. They also suggest that this approach can provide an interesting new methodology for studying implicit processes in cognition. (shrink)

This article takes up the idea of language as a home and dwelling, and reconsiders what this might mean in the context of diasporic bilingualism – where as a ‘heritage speaker’ of a minority language, the ‘mother tongue’ may be experienced as both deeply familiar yet also alien or alienating. Drawing on a range of philosophical and literary accounts (Cassin, Arendt, Anzaldúa, Vuong, among others), this article explores how the so-called ‘mother tongue’ is experienced by heritage speakers in an English-dominant (...) world. From navigating one’s being in-between language-worlds, to the experience of language loss and efforts of reconnection, I argue that bilingual dwelling involves many complex layers often overlooked by philosophical accounts of language that do not attend to the lived world of the migrant and racialised outsider. By turning to the example of bilingual parenting, I then examine how such an undertaking, while labour-intensive, offers opportunities to refresh and co-create language-worlds anew. (shrink)

There is a large gap between the specialized knowledge of scientists and laypeople’s understanding of the sciences. The novice-expert problem arises when non-experts are confronted with (real or apparent) scientific disagreement, and when they don’t know whom to trust. Because they are not able to gauge the content of expert testimony, they rely on imperfect heuristics to evaluate the trustworthiness of scientists. This paper investigates why some bodies of scientific knowledge become polarized along political fault lines. Laypeople navigate conflicting epistemic (...) and social demands in their acceptance of scientific testimony; this might explain their deference to scientific fringe theories, which often goes together with denying established scientific theories. I evaluate three approaches to mitigate denialism: improving the message, improving the messenger, and improving the environment in which the message is conveyed. (shrink)
