Many just war theorists (call them traditionalists) claim that just as people have a right to personal self-defense, so nations have a right to national-defense against an aggressive military invasion. David Rodin claims that the traditionalist is unable to justify most defensive wars against aggression. For most aggressive states only commit conditional aggression in that they threaten to kill or maim the citizens of the nation they are invading only if those citizens resist the occupation. Most wars, then, claimed to (...) be justified by the traditionalist fail to meet the proportionality criterion. Thus, a just war, for Rodin, is best conceived of as a punitive war of law enforcement, not as a war of national-defense. I argue that Rodin does not have a case against the traditionalist. If national-defense is a disproportionate response to conditional aggression, then punitive war is a disproportionate response as well. Furthermore, the belief that punitive war is a proportionate response to conditional aggression underscores the traditionalist’s view that self-determination, cultural identity and the like are of sufficient value to defend by means of lethal force. I end the paper by very briefly sketching an account, different from that of Rodin’s, of how individual nations can be justified in waging wars of law enforcement. (shrink)

Helen Frowe has recently objected to Michael Tooley’s famous Moral Symmetry Principle, which is meant to show that in themselves killing and letting die are morally equivalent. I argue that her objection is not compelling but a more compelling objection is available. Specifically, Tooley’s rebuttal of a proposed counter-example to his Moral Symmetry Principle has two problematic implications. First, it undercuts the very principle itself. If we reject the proposed counter-example, then any instance of the Moral Symmetry Principle will actually (...) demonstrate the moral in-equivalence of killing and letting die. Second, it commits us to the view, which Tooley wishes to avoid, that we are just as obligated to refrain from doing wrong as we are to prevent others from doing the same. I conclude with a brief discussion of a more general concern regarding Tooley’s basic strategy. My focus here is quite narrow. My claims, if plausible, only show that the Moral Symmetry Principle is unsound and thus cannot serve as a basis for the view that killing and letting die are morally equivalent. (shrink)

In a recent article, Xiaofei Liu seeks to defend, from the standpoint of consequentialism, the Doctrine of Doing and Allowing: DDA. While there are various conceptions of DDA, Liu understands it as the view that it is more difficult to justify doing harm than allowing harm. Liu argues that a typical harm doing involves the production of one more evil and one less good than a typical harm allowing. Thus, prima facie, it takes a greater amount of good to justify (...) doing a certain harm than it does to justify allowing that same harm. In this reply, I argue that Liu fails to show, from within a consequentialist framework, that there is an asymmetry between the evils produced by doing and allowing harm. I conclude with some brief remarks on what may establish such an asymmetry. (shrink)

A nation commits mitigated aggression by threatening to kill the citizens of a victim nation if and only if they do not submit to being ruled in a non-egregiously oppressive way. Such aggression primarily threatens a nation’s common way of life . According to David Rodin, a war against mitigated aggression is automatically disproportionate, as the right of lethal self-defense only extends to protecting against being killed or enslaved. Two strategies have been adopted in response to Rodin. The first strategy (...) grants that CWL is insufficiently valuable to lethally defend, however, other considerations can satisfy the proportionality requirement. I argue that this strategy is not persuasive. The second strategy argues for the sufficient value of CWL. This, however, fails to answer the forceful ‘benign dictator’ objection. I respond to this objection by grounding the proportionality of a defensive war in the value of what Phillip Pettit calls ‘anti-power’. (shrink)

Traditional just war theory maintains that the two types of rules that govern justice in times of war, jus ad bellum (justice of war) and jus in bello (justice in war), are logically independent of one another. Call this the independence thesis. According to this thesis, a war that satisfies the ad bellum rules does not guarantee that the in bello rules will be satisfied; and a war that violates the ad bellum rules does not guarantee that the in bello (...) rules will be violated. A controversial implication of this is that it’s possible for soldiers to undergo acts that are instrumental in bringing about victory in an unjust war and yet do nothing morally wrong. Some authors – call them purists – claim that this cannot be correct. Participating in an unjust war is by itself morally wrong. Yitzhak Benbaji has given what is to my mind the strongest defense of the independence thesis. In this paper I critically examine Benbaji’s argument and conclude that it is not persuasive. My argument against Benbaji incorporates the concept of honor in the military. I seek to show, in part, that if the recent literature is correct concerning both the nature of honor and the importance of instilling it in soldiers, then Benbaji hasn’t given the purist a compelling reason to give up her view.

There’s a widespread intuition that if the only way an innocent person can stop her villainous attacker from killing her is to kill him instead, then she is morally permitted to do so. But why is it that she is permitted to employ lethal force on an aggressor if that is what is required to save her life? My primary goal in this paper is to defend David Rodin's fairly recent and under-recognized account of self-defense that answers this question. There (...) are roughly two kinds of non-consequentialist accounts of self-defense:'forced-choice' accounts and 'rights-based' accounts. I first examine what I take to be the most plausible 'forced-choice' account of self-defense and I argue that it is unable to withstand two recent criticisms. I then proceed to adjudicate between two prominent 'rights-based' accounts of self-defense: call them the Thomson/Uniacke account and the Rodinian account. Any rights-based account of self-defense must explain how it is that X, who villainously tries to kill Y, forfeits his right to life. I argue both that Thomson/Uniacke's explanation cannot account for the clear permissibility of killing a certain kind of aggressor in self-defense, and that the attempts that could be made to account for this permissibility are either ad-hoc or permit the killing of persons that are morally on par with innocent bystanders. I point out how Thomson/Uniacke can evade the seeming difficulties that I raise by only permitting lethal defensive force against culpable aggressors. But allowing defensive force to be employed only on the culpable goes against one of their central tenets. I then discuss the Rodinian account, how it evades the criticisms I raise, as well as its other virtues. I conclude that while it has difficulties of its own, it is the more plausible one to adopt.

The following progress report views language acquisition as primarily the attempt to create processes that connect together in a fruitful way linguistic input and other activity. The representations made of linguistic input are thus those that are optimally effective in mediating such interconnections. An effective Language Acquisition Device should contain mechanisms specific to the task of creating the desired interconnection processes in the linguistic environment in which the language learner finds himself or herself. Analysis of this requirement gives clear indications (...) as to what these mechanisms may be. (shrink)

Background Men with antisocial personality disorder show lifelong abnormalities in adaptive decision making guided by the weighing up of reward and punishment information. Among men with antisocial personality disorder, modifi cation of the behaviour of those with additional diagnoses of psychopathy seems particularly resistant to punishment. Methods We did a case-control functional MRI (fMRI) study in 50 men, of whom 12 were violent off enders with antisocial personality disorder and psychopathy, 20 were violent off enders with antisocial personality disorder but (...) not psychopathy, and 18 were healthy non-off enders. We used fMRI to measure brain activation associated with the representation of punishment or reward information during an event-related probabilistic response-reversal task, assessed with standard general linear-model-based analysis. Findings Offenders with antisocial personality disorder and psychopathy displayed discrete regions of increased activation in the posterior cingulate cortex and anterior insula in response to punished errors during the task reversal phase, and decreased activation to all correct rewarded responses in the superior temporal cortex. This finding was in contrast to results for off enders without psychopathy and healthy non-off enders. Interpretation Punishment prediction error signalling in off enders with antisocial personality disorder and psychopathy was highly atypical. This finding challenges the widely held view that such men are simply characterised by diminished neural sensitivity to punishment. Instead, this fi nding indicates altered organisation of the information processing system responsible for reinforcement learning and appropriate decision making. This difference between violent offenders with antisocial personality disorder with and without psychopathy has implications for the causes of these disorders and for treatment approaches. (shrink)

In this introduction, we cover some ways in which the topic of noise is discussed today, and then point to some important open questions about noise and its experience. We then provide a synopsis of the papers collected in the volume.

My interest lies in offering a phenomenological perspective on how noise is experienced, with particular attention to what may be common to different sorts of noise phenomena. As a counterpoint to the notion that noise is an empty or constructed notion, I argue for two desiderata of a phenomenological account of noise; accommodating a plurality of noise experiences, on the one hand, and clarifying their specific phenomenal character, on the other. I then pursue these desiderata by turning to an examination (...) of some contemporary views of perception that have implications for how the phenomenal character of perceptual noise in particular is to be understood; an epistemic misfire view and a sensory misfire view. After clarifying each and its appeal, I convey concerns about the one and the other. I propose a third alternative for further exploration - a perceptual disjoint view - and point to how it ought to explored. On the premise that there is something like a unity of consciousness or experience, I lay out the idea that there may then be many forms of 'disunities' of experience. From an analysis of the latter, I suggest, one may account for many different types of experiences of noise, though with a common ‘phenomenal’ thread running through them. (shrink)

In this book authors for the first time introduce the notion of supermatrices of refined labels. Authors prove super row matrix of refined labels form a group under addition. However super row matrix of refined labels do not form a group under product; it only forms a semigroup under multiplication. In this book super column matrix of refined labels and m × n matrix of refined labels are introduced and studied.

A carne bovina é uma das proteínas mais consumidas no mundo, favorecendo o comércio exterior. O Brasil é um dos grandes exportadores desse produto, o que leva à importância de buscar meios para se obter maior eficiência reprodutiva e produtiva. Dentre esses métodos, o uso de Inseminação Artificial em Tempo Fixo (IATF) vem aumentando e com isso vem a busca por estratégias para alcançar melhores taxas de prenhez. Uma estratégia é avaliar a nutrição do animal em conjunto com a condição (...) corporal. Assim a proposta desse trabalho é verificar a influência do Escore de Condição Corporal (ECC) na taxa de prenhez em vacas Nelore submetidas à IATF. O estudo foi realizado em propriedade particular no município de Cacoal, Rondônia, com 150 vacas da raça Nelore, multíparas, com idade média de 5 anos, submetidas ao manejo de pastejo semi-intensivo. Foram separados dois grupos sendo, grupo A: 75 vacas com escore ≥ 3,0 e grupo B: 75 matrizes com escore ≤2,5. Ambos passaram pelo mesmo protocolo farmacológico, dividido em três etapas (D0, D8 e D10). A inseminação artificial foi realizada no D10 e após 30 dias as vacas dos dois grupos passaram pelo diagnóstico de gestação, por ultrassonografia. Os resultados demonstraram que a taxa de prenhez do grupo A (68%) foi maior que a do grupo B (40%), sendo relevante a preocupação com o ECC de vacas Nelore em protocolos de IATF. (shrink)

Some New Mechanists have proposed that claims of compositional relations are justified by combining the results of top-down and bottom-up interlevel interventions. But what do scientists do when they can perform, say, a cellular intervention, but not a subcellular detection? In such cases, paired interlevel interventions are unavailable. We propose that scientists use abduction and we illustrate its use through a case study of the ionic theory of resting and action potentials.

Standard approaches to ontological simplicity focus either on the number of things or types a theory posits or on the number of fundamental things or types a theory posits. In this paper, I suggest a ground-theoretic approach that focuses on the number of something else. After getting clear on what this approach amounts to, I motivate it, defend it, and complete it.

The acquisition of a new skill usually proceeds through five stages, from novice to expert, with a sixth stage of mastery available for highly motivated performers. In this chapter, we re-state the six stages of the Dreyfus Skill Model, paying new attention to the transitions and interrelations between them. While discussing the fifth stage, expertise, we unpack the claim that, “when things are proceeding normally, experts don’t solve problems and don’t make decisions; they do what normally works” (Dreyfus & Dreyfus, (...) 1988, pp. 30 – 31). This leads us to offer an account of the “perspectival deliberation” that arises for experts and masters and that is distinct from the calculative deliberation characteristic of the lower stages of skillfulness.

In the wake of the advent of genome editing technology CRISPR-Cas9 (clustered regularly interspaced palindromic repeat (CRISPR)-associated protein 9), there has been a global debate around the implications of manipulating the human genome. While CRISPR-based germline gene editing is new, the debate about the ethics of gene editing is not – for several decades now, scholars have debated the ethics of making heritable changes to the human genome. The arguments that have been raised both for and against the use of (...) genetic technologies in human reproduction reiterate much of the arguments made in the pre-CRISPR debate. As such, it is instructive for South Africa to reflect on these arguments now, in considering our position on the regulation of the use of this novel biotechnology. There are two dominant schools of thought in this area, bioliberalism and bioconservatism. Bioconservatives raise concerns about the risks of genetic manipulation, and argue that it ought to be limited or prohibited to avert these risks to human health and human nature. Bioliberal scholars are more open to the prospect of genetic manipulation, because of its potential utility. In this article, I conclude that in liberal democracies such as our own, bioliberal arguments ought to be seriously considered when formulating policy on human genome editing because of the extent to which they resonate with our Constitutional values and human rights. I further suggest that there is a need for an enquiry into the relevance of African perspectives on the ethical questions that arise concerning germline genome editing. (shrink)

Early Heidegger argues that a “homogenous space of nature” can be revealed by stripping away the intelligibility of Dasein's everyday world, a process he calls “deworlding.” Given this, some interpreters have suggested that Heidegger, despite not having worked out the details himself, is also committed to a notion of deworlded time. Such a “natural time” would amount to an endogenous sequentiality in which events are ordered independently of Dasein and the stand it takes on its being. I show that Heidegger (...) was indeed committed to such a temporal realism even though his treatment of these issues is somewhat scattered and pulled in different directions. In the course of my reconstruction, I renew an interpretation of Heidegger that stresses Dasein's thrownness into nature and I answer William Blattner's powerful interpretation of Heidegger as a failed temporal idealist who was unable to derive the sequentiality of ordinary time from Dasein's non-sequential originary temporality. Heidegger did not attempt to derive sequentiality; instead, he understood it as a built-in feature of the natural universe by which Dasein's activities are constrained. World-time turns out to be a co-production of Dasein's non-sequential originary temporality and the endogenous sequentiality of events in nature. (shrink)

In this paper, I argue that self-awareness is intertwined with one's awareness of possibilities for action. I show this by critically examining Dan Zahavi's multidimensional account of the self. I argue that the distinction Zahavi makes among 'pre-reflective minimal', 'interpersonal', and 'normative' dimensions of selfhood needs to be refined in order to accommodate what I call 'pre-reflective self-understanding'. The latter is a normative dimension of selfhood manifest not in reflection and deliberation, but in the habits and style of a person’s (...) pre-reflective absorption in the world. After reviewing Zahavi's multidimensional account and revealing this gap in his explanatory taxonomy, I draw upon Heidegger, Merleau-Ponty, and Frankfurt in order to sketch an account of pre-reflective self-understanding. I end by raising an objection to Zahavi’s claim for the primitive and foundational status of pre-reflective self-awareness. To carve off self-awareness from the self’s practical immersion in a situation where things and possibilities already matter and draw one to act is to distort the phenomena. A more careful phenomenology of pre-reflective action shows that pre-reflective self-awareness and pre-reflective self-understanding are co-constitutive, both mutually for each other and jointly for everyday experience.

In 2035 global egg demand will have risen 50% from 1985. Because we are not able to tell in the egg whether it will become a male or female chick, billons of one day-old male chicks will be killed. International research initiatives are underway in this area, and governments encourage the development of an alternative with the goal of eliminating the culling of day-old male chicks. The Netherlands holds an exceptional position in the European egg trade, but is also the (...) only country in the European Union where the downside of the egg sector, the practice of killing day-old male chicks, is a recurrent subject of societal debate. ‘Preventing the killing of young animals’ and ‘in ovo sex determination’ are the two alternative approaches available to solve this problem. It is clear that both approaches solve the problem of killing day-old male chicks, either by keeping them alive or by preventing them from living, but they also raise a lot of new animal welfare-related dilemmas. A thorough analysis was undertaken of these dilemmas and the results are presented in this article. The analysis resulted in an ethical framework based on the two main approaches in bioethics: a consequentialist approach and a deontological approach. This ethical framework was used to develop an online survey administered to ascertain Dutch public opinion about these alternative approaches. The results show that neither alternative will be fully accepted, or accepted by more than half of Dutch society. However, the survey does provide an insight into the motives that are important for people’s choice: food safety and a good treatment of animals. Irrespective of the approach chosen, these values should be safeguarded and communicated clearly. (shrink)

The problem of religious disagreement between epistemic peers is a potential threat to the epistemic justification of one’s theistic belief. In this paper, I develop a response to this problem which draws on the central epistemological thesis of skeptical theism concerning our inability to make proper judgements about God’s reasons for permitting evil. I suggest that this thesis may extend over to our judgements about God’s reasons for self-revealing, and that when it does so, it can enable theists to remain (...) steadfast amid disagreement with epistemic peers who hold a contrary theistic belief (i.e., atheistic belief). For if we’re unable to make proper judgements about God’s reasons for self-revealing, then for all we know, God has some reason for not revealing Himself to our apparent epistemic peer. Thus, their epistemic credentials needn’t provide reason to reduce one’s confidence to such a degree as to no longer uphold one’s theistic belief. (shrink)

This paper provides an interpretation of the existential conception of selfhood that follows from Merleau-Ponty’s account of perception. On this view, people relate to themselves not by “looking within” in acts of introspection but, first, by “looking without” at the field of solicitations in which they are immersed and, eventually, in Merleau-Ponty’s words, by “making explicit” the “melodic unity” or “immanent sense” of their behavior. To make sense of this, I draw out a distinction latent in Merleau-Ponty’s view between a (...) pre-reflective sense of self and a reflective self-interpretation. The former is a suite of abilities and dispositions in light of which a person is aware of and drawn to act in a situation. This sense of self undergoes transitions over time, is constitutively susceptible to moments of disorientation, and tends toward but never achieves full coherence. Reflective self-interpretation is an activity whereby someone—provisionally and defeasibly—clarifies, articulates, and gets a better “grip” on how they are prereflectively drawn to act. I ground this interpretation in a detailed reading of Merleau-Ponty’s treatment of romantic love and I corroborate it by examining his account of the emergence of class-consciousness in the self-interpretation of a worker.

In common with traditional forms of epistemic internalism, epistemological disjunctivism attempts to incorporate an awareness condition on justification. Unlike traditional forms of internalism, however, epistemological disjunctivism rejects the so-called New Evil Genius thesis. In so far as epistemological disjunctivism rejects the New Evil Genius thesis, it is revisionary. -/- After explaining what epistemological disjunctivism is, and how it relates to traditional forms of epistemic internalism / externalism, I shall argue that the epistemological disjunctivist’s account of the intuitions underlying the New (...) Evil Genius thought experiment is at best incomplete. As presented, therefore, epistemological disjunctivism is unable to accommodate the core guiding intuitions of epistemic internalism. Given the stated aim of not being revisionary on this score, the view is at a dialectical disadvantage over the traditional forms of epistemic internalism the position is meant to replace. Unfortunately, therefore, at present, the impasse between internalism and externalism remains. (shrink)

The New Evil Demon problem has been hotly debated since the case was introduced in the early 1980’s (e.g. Lehrer and Cohen 1983; Cohen 1984), and there seems to be recent increased interest in the topic. In a forthcoming collection of papers on the New Evil Demon problem (Dutant and Dorsch, forthcoming), at least two of the papers, both by prominent epistemologists, attempt to resist the problem by appealing to the distinction between justification and excuses. My primary aim here is (...) to critically evaluate this new excuse maneuver as a response to the New Evil Demon problem. -/- Their response attempts to give us reason to reject the idea that victims of the New Evil Demon have justification for believing as they do. I shall argue that this approach is ultimately unsuccessful, however much of value can be learned from these attempts. In particular, progress in the debate can be made by following those who advance the excuse maneuver and make explicit the connection between epistemic justification and epistemic norms. By doing so, the questions being debated are clarified, as is the methodology being used to attempt to answer them. (shrink)

In this article, I consider how the epistemic problem of religious disagreement has been viewed within the Islamic tradition. Specifically, I consider two religious epistemological trends within the tradition: Islamic Rationalism and Islamic Traditionalism. In examining the approaches of both trends toward addressing the epistemic problem, I suggest that neither is wholly adequate. Nonetheless, I argue that both approaches offer insights that might be relevant to building a more adequate response. So, I attempt to combine insights from both by drawing (...) a distinction between inferential and noninferential reflective responsibility. Given this distinction, I argue that it may be possible for a theist to remain steadfast in upholding their tradition-specific theistic belief, without having to hold that belief by way of inference; but nevertheless, having to be sufficiently reflectively responsible in forming their theistic belief noninferentially.

The generative AI boom is unleashing its minions. Enterprise software vendors have rolled out legions of automated assistants that use large language model (LLM) technology, such as ChatGPT, to offer users helpful suggestions or to execute simple tasks. These so-called copilots and chatbots can increase productivity and automate tedious manual work. In this article, we explain how that leads to the risk that users' ethical competence may degrade over time — and what to do about it.

Influential cases have been provided that seem to suggest that one can fail to have knowledge because of the social environment. If not a distinct kind of social defeater, is there a uniquely social phenomenon that defeats knowledge? My aim in this paper is to explore these questions. I shall argue that despite initial appearances to the contrary, we have no reason to accept a special class of social defeater, nor any essentially social defeat phenomenon. We can explain putative cases (...) of social defeat with our existing epistemological apparatus. (shrink)

In this article I argue that the value of epistemic justification cannot be adequately explained as being instrumental to truth. I intend to show that false belief, which is no means to truth, can nevertheless still be of epistemic value. This in turn will make a good prima facie case that justification is valuable for its own sake. If this is right, we will have also found reason to think that truth value monism is false: assuming that true belief does (...) have value, there is more of final epistemic value than mere true belief.

Moral options are permissions to do less than best, impartially speaking. In this paper, we investigate the challenge of reconciling moral options with the ideal of justifiability to each individual. We examine ex-post and ex-ante views of moral options and show how they might conflict with this ideal in single-choice and sequential-choice cases, respectively. We consider some ways of avoiding this conflict in sequential-choice cases, showing that they face significant problems.

Both Martin Heidegger and Harry Frankfurt have argued that the fundamental feature of human identity is care. Both contend that caring is bound up with the fact that we are finite beings related to our own impending death, and both argue that caring has a distinctive, circular and non-instantaneous, temporal structure. In this paper, I explore the way Heidegger and Frankfurt each understand the relations among care, death, and time, and I argue for the superiority of Heideggerian version of this (...) nest of claims. Frankfurt claims that we should conceive of the most basic commitments which practically orient a person in the world and define his identity (“volitional necessities”) as naturalistic facts, foundational for and located completely without the normative space of reasons. In support of this he appeals to the supposedly foundational role played in human life by the instinct for self-preservation, what Frankfurt calls the “love of living.” The claim is that in questions of practical identity there is a definite priority of the factual over the normative. Frankfurt’s naturalistic model of volitional necessity is motivated by a misunderstanding of the temporal structure of care, a misunderstanding that helps lead him to an implausible conception of the basic structures of human identity. Heidegger advances an anti-naturalistic conception of caring, one bound up with his way of understanding how human beings relate to their own future. I argue that the existential, temporal, and normative significance that Frankfurt attributes to the naturalized “love of living” is better captured by the Heideggerian claim that human identity is defined by being “for-the-sake-of” certain projects and commitments, a way of being lived out in the way Heidegger calls “being-towards-death.”.

This paper explores the notion of the self as one of the main obstacles in advancing neuroscience. Some folks argue for strict naturalism in order to study the brain objectively. However, in this process of naturalization, we run the risk of losing key components that make up our experience as human beings, namely emotions, ideas, and values. Therefore, I argue for moderate naturalism in an attempt to reconcile with the self. I reference Immanuel Kant’s moral law theory in order to (...) discuss the ethical implications of following a moderate naturalist view of the self in advancing neuroscience. (shrink)

What is it to be a woman? What is it to be a man? We start by laying out desiderata for an analysis of 'woman' and 'man': descriptively, it should link these gender categories to sex biology without reducing them to sex biology, and politically, it should help us explain and combat traditional sexism while also allowing us to make sense of the activist view that gendering should be consensual. Using a Putnam-style 'Twin Earth' example, we argue that none of (...) the existing analyses in the feminist literature succeeds in meeting all of our desiderata. Finally, we propose a positive account that we believe can satisfy all the desiderata outlined. According to our theory, the genders 'woman' and 'man' are individuated not by their contemporary connections to sex biology, but by their historical continuity with classes that were originally closely connected to sex biology.

What makes an intellectual virtue a virtue? A straightforward and influential answer to this question has been given by virtue-reliabilists: a trait is a virtue only insofar as it is truth-conducive. In this paper I shall contend that recent arguments advanced by Jack Kwong in defence of the reliabilist view are good as far as they go, in that they advance the debate by usefully clarifying ways in how best to understand the nature of open-mindedness. But I shall argue that (...) these considerations do not establish the desired conclusions that open-mindedness is truth-conducive. To establish these much stronger conclusions we would need an adequate reply to what I shall call Montmarquet’s objection. I argue that Linda Zagzebski’s reply to Montmarquet’s objection, to which Kwong defers, is inadequate. I conclude that it is contingent if open-mindedness is truth-conducive, and if a necessary tie to truth is what makes an intellectual virtue a virtue, then the status of open-mindedness as an intellectual virtue is jeopardised. We either need an adequate reliabilist response to Montmarquet’s objection, or else seek alternative accounts of what it is that makes a virtue a virtue. I conclude by briefly outlining some alternatives. (shrink)

Scientific hedges are communicative devices used to qualify and weaken scientific claims. Gregor Betz has argued—unconvincingly, we think—that hedging can rescue the value-free ideal for science. Nevertheless, Betz is onto something when he suggests there are political principles that recommend scientists hedge public-facing claims. In this article, we recast this suggestion using the notion of public justification. We formulate and reject a Rawlsian argument that locates the justification for hedging in its ability to forge consensus. On our alternative proposal, hedging (...) is often justified because it renders scientific claims as publicly accessible reasons. (shrink)

We start by recalling the basics of Woodruff’s system and by bringing to light some of its notable features. We then go on to elaborate on some of the difficulties attached to it; on our (...) way to offer a possible solution to such difficulties, we discuss the relation between Woodruff’s system and two-dimensional semantics for many-valued logics, as developed by Hans Herzberger.

According to Heidegger's Being and Time, social relations are constitutive of the core features of human agency. On this view, which I call a ‘strong conception’ of sociality, the core features of human agency cannot obtain in an individual subject independently of social relations to others. I explain the strong conception of sociality captured by Heidegger's underdeveloped notion of ‘being-with’ by reconstructing Heidegger's critique of the ‘weak conception’ of sociality characteristic of Kant's theory of agency. According to a weak conception, (...) sociality is a mere aggregation of individual subjects and the core features of human agency are built into each individual mind. The weak conception of sociality remains today widely taken for granted. I show that Christine Korsgaard, one of the most creative contemporary appropriators of Kant, operates with a weak conception of sociality and that this produces a problematic explanatory deficiency in her view: she is unable to explain the peculiar motivational efficacy of shared social norms. Heidegger's view is tailor made to explain this phenomenon. I end by sketching how Heidegger provides a social explanation of a major systematic concern animating Korsgaard, the concern with the importance of individual autonomy and answerability in human life.

Atualmente, biotecnologias são empregadas na forma de protocolos a fim de sincronizar o crescimento folicular e a ovulação, bem como permitir que vacas atuem como receptoras de embriões visando melhorar o potencial genético do rebanho. O objetivo desse estudo foi avaliar o efeito da utilização de implantes intravaginais de progesterona de 1º, 2º e 3º uso no protocolo de transferência de embriões em tempo fixo (TETF) sobre a taxa de prenhez em receptoras girolandas. O experimento ocorreu em uma fazenda localizada (...) no município de São Sebastião do Maranhão (MG). Foram utilizadas 74 vacas submetidas aos seguintes protocolos: No dia 0 (D0) administrou-se 2 ml de 17β-Estradiol e progesterona e foi colocado o implante intravaginal de progesterona. Estes implantes foram colocados de forma aleatória, sendo de 1° uso (grupo 1; n=15), 2° (grupo 2; n=24) ou 3° (grupo 3; n=35).No D8, os implantes foram retirados e administrou-se 2 ml PGF2α; 1,5 ml de eCG e 1 ml de 17β-Estradiol e progesterona. A inovulação dos embriões in vitroo correu no D (16) para todas as vacas que apresentaram um corpo lúteo. As variáveis qualitativas (prenhe ou não prenhe) foram comparadas em tabelas de contingência e analisadas pelo teste de qui-quadrado a 5% de probabilidade. Neste estudo não houve diferença estatística entre os grupos protocolados em relação ao aproveitamento como receptoras: 1º uso (53,3%), 2º (79,2%) e 3º (68,65). Ademais, observou-se uma taxa de prenhez entre os grupos de 37,5% para o 1º uso, 42,1% para o 2º e 33,3% para o 3º (P>0,05). Dentre as vantagens ao reaproveitamento dos implantes multiusos destaca-se a redução dos custos dos protocolos hormonais, já que a progesterona é o hormônio mais oneroso, desta forma, a maximização do uso reduz o valor final do protocolo sem prejuízos a taxa de prenhez.

In general, epistemic internalists hold that an individual’s justification for a belief is exhausted by her reflectively accessible reasons for thinking that the contents of her beliefs are true. Applying this to the epistemology of testimony, a hearer’s justification for beliefs acquired through testimony is exhausted by her reflectively accessible reasons to think that the contents of the speaker’s testimony is true. A consequence of internalism is that subjects that are alike with respect to their reflectively accessible reasons are alike (...) with respect to what they have justification to believe. Testimony should be thought no different: hearers that are alike with respect to reflectively accessible reasons to think that a speaker’s testimony is true are alike with respect to their justification for beliefs based upon that testimony. But it has been recently argued that this view faces powerful counterexamples. So the central question is this: assuming that a hearer can acquire justification to believe a proposition through the testimony of a speaker, can epistemic internalism provide the resources to explain how such justification is possible? My aim in this paper is to address these counterexamples, and in so doing, defend epistemic internalist accounts of testimony. (shrink)

Abstract: Lemons are an important fruit that have a wide range of uses and benefits, from culinary to health to household and beauty applications. Deep learning techniques have shown promising results in image classification tasks, including fruit quality detection. In this paper, we propose a convolutional neural network (CNN)-based approach for detecting the quality of lemons by analysing visual features such as colour and texture. The study aims to develop and train a deep learning model to classify lemons based on (...) their quality, evaluate the model's performance, compare it to traditional machine learning approaches, and identify key factors that affect the model's performance. The dataset used in the study consists of approximately 2533 images of lemons and an empty surface, divided into training, test, and validation data, and includes images of both good and bad quality lemons under different lighting conditions. The deep learning model achieved an accuracy of 99.74% on the test dataset and outperformed traditional machine learning approaches. The developed model has the potential to improve efficiency and accuracy in lemon quality control in the agriculture and food industry. (shrink)

Does the recent success of Podemos and Syriza herald a new era of inclusive, egalitarian left populism? Because leaders of both parties are former students of Ernesto Laclau and cite his account of populism as guiding their political practice, this essay considers whether his theory supports hope for a new kind of populism. For Laclau, the essence of populism is an “empty signifier” that provides a means by which anyone can identify with the people as a whole. However, the concept (...) of the empty signifier is not as neutral as he assumes. As I show by analyzing the role of race in his theory, some subjects are constituted in a way that prevents their unmediated identification with the people. Consequently, Laclau’s view should be read as symptomatic of the problems with populist logic if its adherents are to avoid reproducing its exclusions and practice a more inclusive politics.

This chapter first surveys general issues in the epistemic internalism / externalism debate: what is the distinction, what motivates it, and what arguments can be given on both sides. -/- The second part of the chapter will examine the internalism / externalism debate as regards to the specific case of the epistemology of memory belief.

Epistemic internalism, by stressing the indispensability of the subject’s perspective, strikes many as plausible at first blush. However, many people have tended to reject the position because certain kinds of beliefs have been thought to pose special problems for epistemic internalism. For example, internalists tend to hold that so long as a justifier is available to the subject either immediately or upon introspection, it can serve to justify beliefs. Many have thought it obvious that no such view can be correct, (...) as it has been alleged that internalism cannot account for the possibility of the justification of beliefs stored in memory. -/- My aim in this paper is to offer a response that explains how memory justification is possible in a way that is consistent with epistemic internalism and an awareness condition on justification. Specifically, I will explore the plausibility of various options open to internalists, including both foundationalist and non-foundationalist approaches to the structure of justification. I intend to show that despite other difficult challenges that epistemic internalism might face, memory belief poses no special problems that the resources of internalism cannot adequately address.

The APA has recently taken steps to address concerns related to teaching and supporting philosophers and students who come from less privileged backgrounds. I want to add to this project by fleshing out some concrete ways that philosophy professors contribute to the challenges faced by first-generation and financially disadvantaged philosophers and students. I hope that in making these behaviors explicit, it may be easier for faculty to acknowledge and overcome them.

Moral judgments about an action are influenced by the action’s intentionality. The reverse is also true: judgments of intentionality can be influenced by an action’s moral valence. For example, respondents judge a harmful side-effect of an intended outcome to be more intentional than a helpful side-effect. Debate continues regarding the mechanisms underlying this “side-effect effect” and the conditions under which it will persist. The research behind this chapter tested whether the side-effect effect is intact in adolescents with psychopathic traits, who (...) are characterized by persistent immoral behavior, deficient moral emotions, and impairments in some forms of moral judgment. Results showed no differences between healthy adolescents and those with psychopathic traits: both groups judged harmful side-effects to be more intentional than helpful side-effects by an approximately 2:1 ratio. The chapter discusses these results in light of hypothesized mechanisms underlying the side-effect effect, and in light of our current understanding of moral reasoning deficits in psychopathy.

The current resurgence of interest in cognition and in the nature of cognitive processing has brought with it also a renewed interest in the early work of Husserl, which contains one of the most sustained attempts to come to grips with the problems of logic from a cognitive point of view. Logic, for Husserl, is a theory of science; but it is a theory which takes seriously the idea that scientific theories are constituted by the mental acts of cognitive subjects. (...) The present essay begins with an exposition of Husserl's act-based conception of what a science is, and goes on to consider his account of the role of linguistic meanings, of the ontology of scientific objects, and of evidence and truth. The essay concentrates almost exclusively on the Logical Investigations of 1900/01. This is not only because this work, which is surely Husserl's single most important masterpiece, has been overshadowed first of all by his Ideas I and then later by the Crisis. It is also because the Investigations contain, in a peculiarly clear and pregnant form, a whole panoply of ideas on logic and cognitive theory which either simply disappeared in Husserl's own later writings or became obfuscated by an admixture of that great mystery which is 'transcendental phenomenology'.

In this article, we discuss some of the challenges related to formulating and adopting a realist position regarding non-relativistic quantum mechanics. In a standard approach to ontology, the ontological commitments of scientific theories can be extracted from them. Scientific realism is the standpoint that our best scientific theories are approximately true, and thus, their ontological commitments, roughly speaking, correspond to reality. Quantum mechanics complicates this view by introducing an interpretational requirement that links a particular conception of how reality should be (...) to the theory. This generates comprehensive difficulties: when we separate theory and interpretation, we have a clear conception of theory but not of interpretation and how to extract its ontology. On the other hand, if we somehow identify theory and interpretation, we have a reasonably clear conception of the desired ontology but lose our best characterizations of theory, rendering our methods for extracting ontology ineffective. Our aim is to map out the challenges for future rigorous realist approaches to quantum mechanics. (shrink)

Context — Children and adults with psychopathic traits and conduct or oppositional defiant disorder demonstrate poor decision making and are impaired in reversal learning. However, the neural basis of this impairment has not previously been investigated. Furthermore, despite high comorbidity of psychopathic traits and attention deficit/hyperactivity disorder, to our knowledge, no research has attempted to distinguish neural correlates of childhood psychopathic traits and attention-deficit/hyperactivity disorder. Objective—To determine the neural regions that underlie the reversal learning impairments in children with psychopathic traits (...) plus conduct or oppositional defiant disorder. Design — Case-control study. Setting — Government clinical research institute. Participants — Forty-two adolescents aged 10 to 17 years: 14 with psychopathic traits and oppositional defiant disorder or conduct disorder, 14 with attention-deficit/hyperactivity disorder only, and 14 healthy controls. Main Outcome Measure — Blood oxygenation level–dependent signal as measured via functional magnetic resonance imaging during a probabilistic reversal task. Results — Children with psychopathic traits showed abnormal responses within the ventromedial prefrontal cortex (Brodmann area 10) during punished reversal errors compared with children wit hattention deficit/hyperactivity disorder and healthy children (P < .05 corrected for multiple comparisons). Conclusions — To our knowledge, this study provides the first evidence of abnormal ventromedial prefrontal cortex responsiveness in children with psychopathic traits and demonstrates this dysfunction was not attributable to comorbid attention-deficit/hyperactivity disorder. These findings suggest that reversal learning impairments in patients with developmental psychopathic traits relate to abnormal processing of reinforcement information. (shrink)
