El desarrollo del pensamiento crítico en la educación superior se inscribe en un contexto de transición de paradigmas. El paso de la modernidad a la postmodernidad y lo que esto significa en términos de modificación de parámetros de comprensión, de transformaciones en los ámbitos político, económico, social y cultural genera cambios en el sujeto. Desde experiencia docente se hace evidente la ausencia de pensamiento crítico en los estudiantes de los primeros niveles de educación superior, y por ello, la necesidad de (...) implementaciones didácticas innovadoras en el proceso de enseñanza. El presente documento tiene como objetivo presentar los aportes de la didáctica al desarrollo del pensamiento crítico en estudiantes de educación superior. Se trata de una revisión de tipo exploratoria-descriptiva; de carácter bibliográfico y con enfoque cualitativo. Se concluye que, la didáctica permite a los docentes orientar de manera consciente y creativa el proceso de enseñanza aprendizaje, ya que, al ser selectivos en los distintos métodos y técnicas aplicados en el proceso educativo contribuyen para potenciar el desarrollo del pensamiento crítico y para el desarrollo de capacidades cognoscitivas, sociales y afectivas integradoras de análisis, puntos de vista, problemas, decisiones y posturas que permiten en mejor desenvolvimiento del sujeto en el contexto.

The current assessment of behaviors in the inventories to diagnose autism spectrum disorders (ASD) focus on observation and discrete categorizations. Behaviors require movements, yet measurements of physical movements are seldom included. Their inclusion however, could provide an objective characterization of behavior to help unveil interactions between the peripheral and the central nervous systems. Such interactions are critical for the development and maintenance of spontaneous autonomy, self-regulation and voluntary control. At present, current approaches cannot deal with the heterogeneous, dynamic and stochastic (...) nature of development. Accordingly, they leave no avenues for real-time or longitudinal assessments of change in a coping system continuously adapting and developing compensatory mechanisms. We offer a new unifying statistical framework to reveal re-afferent kinesthetic features of the individual with ASD. The new methodology is based on the non-stationary stochastic patterns of minute fluctuations (micro-movements) inherent to our natural actions. Such patterns of behavioral variability provide re-entrant sensory feedback contributing to the autonomous regulation and coordination of the motor output. From an early age, this feedback supports centrally driven volitional control and fluid, flexible transitions between intentional and spontaneous behaviors. We show that in ASD there is a disruption in the maturation of this form of proprioception. Despite this disturbance, each individual has unique adaptive compensatory capabilities that we can unveil and exploit to evoke faster and more accurate decisions. Measuring the kinesthetic re-afference in tandem with stimuli variations we can detect changes in their micro-movements indicative of a more predictive and reliable kinesthetic percept. Our methods address the heterogeneity of ASD with a personalized approach grounded in the inherent sensory-motor abilities that the individual has already developed. (shrink)

RELAÇÃO E EFEITOS BIOQUÍMICO-NUTRICIONAIS SOBRE AS ALTERAÇÕES DO CORPO LÚTEO EM VACAS -/- Emanuel Isaque Cordeiro da Silva Departamento de Agropecuária – IFPE Campus Belo Jardim [email protected] ou [email protected] WhatsApp: (82)98143-8399 -/- •__7. ALTERAÇÕES DO CORPO LÚTEO -/- A estrutura funcional desenvolve-se a partir da cavidade folicular após a ovulação. O corpo lúteo é constituído pelas células da teca interna (pequenas e ativas na primeira fase do seu desenvolvimento) e células da granulosa (grandes e ativas na segunda metade do seu (...) desenvolvimento). As principais características de cada tipo de célula podem resumir-se da seguinte forma: As células pequenas são mais sensíveis à ação da LH porque possui uma quantidade maior de receptores biologicamente ativos para esta hormona e a resposta é mediada pelo sistema AMPc-adelinato ciclase. As grandes células lúteas têm menos receptores para a LH (a maior quantidade são para a PGF2α e a PGE2), e são as responsáveis pela produção da oxitocina luteal (BAH, et al. 2006; CAMPO, 2003). Contrariamente às pequenas células lúteas, a produção de progesterona (P4) é parcialmente controlada pelo sistema Ca+2 - Fosfatil inositol-quinase C (CAMPO, 2003). A regulação da função do corpo lúteo é um mecanismo complexo. Nela intervêm fatores tróficos e líticos que estão presentes em forma simultânea durante todo o ciclo estral, e portanto a estimulação ou inibição da síntese e secreção de P4 depende do balanço entre estes fatores. (CAMPO, 2003). Dentro dos fatores tróficos, os nutrientes desempenham um papel relevante sobre a luteólise e as funções luteotrópicas, entre estas pode-se citar a ação das seguintes: -/- 7.1 Vitaminas Deficiência em betacarotenos. Vitamina A é um termo genérico que designa qualquer composto com atividade de retinol, o trans-retinol, é o composto base, sua forma aldeído e ácido são chamados de retinol e ácido retinóico, respectivamente. Por outro lado, a forma ativa da Vitamina A participa no mecanismo da visão, como 11-cis-retinal. Adicionalmente, o betacaroteno, considerado uma provitamina A é a única forma em que esta encontra nas plantas. Em sentido nutricional, a família da Vitamina A compreende todos os compostos que possuem atividade de retinol, incluindo cerca de cinquenta carotenoides que possuem atividade de provitamina A, aceitando-se que o mais ativo é o trans-betacaroteno (TORRES, et al. 2002). As vitaminas que são necessárias para o crescimento e a produção, também são essenciais para a reprodução. As recomendações atuais de vitamina A são de 75.000 UI/dia durante a lactação e 80.000 UI/dia (nota: 1 mg de Vitamina A = 400 UI) durante o período seco nas vacas leiteiras. A suplementação com vitamina A tem pouco risco de toxicidade, enquanto a sua deficiência pode retardar o aparecimento do primeiro cio/estro, induzir cios/estros silenciosos, aumentar o número de quistos ováricos, reduzir os índices de concepção, causar abortos, mortes embrionárias e ocasionar o nascimento de bezerros debilitados e fracos, uma vez que não irão nascer com os índices e requerimentos ideais de nutrientes passados da mãe para o feto pela placenta, e que, já que a mãe possui deficiência nutricional, o colostro não terá o efeito completo para passar a imunidade essencial ao neonato. Embora os mecanismos de ação não sejam claros, foram notificadas maiores secreções de esteroides ováricos quando as concentrações de β-carotenos no fluido folicular foram elevadas; logo, foram observadas maiores concentrações elevadas de β- estradiol e vitamina A nos folículos que terminaram em ovulação do que naqueles que terminaram em atresia. Para evitar as perdas reprodutivas por deficiência de vitamina A, pode-se optar pela administração oral ou injetável desta ao animal, mediante dois métodos: o primeiro consiste em adicionar 1 a 2,5 kg de premix vitamínico em 1 tonelada de grãos o que supre de 4 a 6.000 UI o que é desejável; o segundo é a administração via injetável em quantidades vide bula do fármaco. 7.2 Minerais O excesso de fósforo é absorvido principalmente no intestino delgado dos mamíferos através de um mecanismo de transporte ativo dependente do sódio, que é estimulado pela pró-hormona 1,25- hidroxivitamina D3. Os ruminantes são capazes de absorver o fósforo dietético em proporção direta às quantidades presentes na ração. Estima-se que aproximadamente 1% do corpo animal é composto de fósforo, do qual 85% está presente nos dentes e no tecido ósseo. Os tecidos moles são capazes de conter entre 0,15-0,20% de fósforo sob a forma de fosfoproteínas, nucleoproteínas, fosfolipídios, fosfato creatinina, adenosintrifosfato, glicose-6-fosfato, etc. Ao nível do plasma sanguíneo, o fósforo apresenta valores de 12,09 mg/dl. Os valores plasmáticos de fósforo são regulados principalmente pelo rim, sendo observado um aumento na excreção urinária do elemento inorgânico quando este excede a capacidade de transporte (REBOLLAR & MATEOS, 1999). O fósforo faz parte dos fosfolipídios, que são importantes no transporte de lipídios e seu metabolismo, como componente das membranas celulares. O fosfato faz parte do RNA e do DNA, componentes celulares vitais, e são essenciais para a síntese proteica. O fosfato faz parte de sistemas enzimáticos como a cocarboxilase e NAD, portanto está envolvido em todos os processos de síntese e regulação energética, dado que o corpo lúteo requer altas quantidades de energia para a síntese celular e hormonal, um excesso de fósforo pode bloquear a capacidade renal da sua regulação gerando um desequilíbrio catiônico que descompensa a relação Na:K, já que deverão ser excretados íons fosfato para regular o equilíbrio ácido-básico, desta forma, os processos celulares em tecidos de alta sensibilidade como o ovário serão afetados em sua função. A situação para prevenção de problemas relacionados ao fósforo (P) já foi tratada em assuntos anteriores, porém, sempre vale frisar para o leitor fiel que me lê que as exigências de P presentes na matéria seca (MS) variam entre 0,17 e 0,59% de P por kg/MS para bovinos de corte e em 0,32 a 0,44% por kg/MS para o gado leiteiro. Dessa forma, dados obtidos por pesquisas, ditam que para a mantença de uma vaca ou quaisquer outra categoria bovina o ideal é o consumo de 1.43 g/100 kg de peso vivo (PV), garantindo assim a prevenção de possíveis afecções reprodutivas como as alterações do corpo lúteo. Gramíneas, forragens, leguminosas e os concentrados fornecem muito bem os requerimentos de fósforo para os animais, todavia deve-se estar atento as relações e dependências do P com outros elementos como o Ca e a relação Na:K (10-15:1 idealmente). 7.3 Compostos estrogênicos Os fitoestrogênios afetam repetidamente a estabilidade do corpo lúteo. Os compostos estrogênicos encontrados principalmente em leguminosas pertencem principalmente a três grupos: isoflavanos, isoflavonas, presentes no gênero Trifolium e praticamente restritos às leguminosas, e cumestanos, que foram estudados na alfafa (Medicago sativa) e na Melilotus alba. Todas as isoflavonas sofrem algum grau de transformação no rúmen, sendo o Isoflavonoide formononetina, na realidade um pró-estrógeno, o único que se ativa no ecossistema ruminal ao ser convertido em equol, enquanto que as demais são degradadas a produtos inativos (RAMOS, et al. 1998). Por fim, a alta concentração no sangue do equol retarda a retroalimentação sobre a hipófise mediante a qual se reduzem os níveis de FSH para dar lugar à onda ovulatória de LH, se esta não ocorrer, o corpo lúteo obviamente não se formará. O conhecimento acerca dos estrogênios na alimentação animal é defasado nos livros sobre o tema, no entanto, o criador pode ficar tranquilo no que tange o tema na prática da sua fazenda e dos seus animais, uma vez que tal elemento é muito bem fornecido naturalmente por meio dos alimentos volumosos presentes no seu pasto. -/- Apoio -/- Realização -/- REFERÊNCIAS BIBLIOGRÁFICAS BAH, Mamadou M. et al.

Neuroenhancement involves the use of neurotechnologies to improve cognitive, affective or behavioural functioning, where these are not judged to be clinically impaired. Questions about enhancement have become one of the key topics of neuroethics over the past decade. The current study draws on in-depth public engagement activities in ten European countries giving a bottom-up perspective on the ethics and desirability of enhancement. This informed the design of an online contrastive vignette experiment that was administered to representative samples of 1000 respondents (...) in the ten countries and the United States. The experiment investigated how the gender of the protagonist, his or her level of performance, the efficacy of the enhancer and the mode of enhancement affected support for neuroenhancement in both educational and employment contexts. Of these, higher efficacy and lower performance were found to increase willingness to support enhancement. A series of commonly articulated claims about the individual and societal dimensions of neuroenhancement were derived from the public engagement activities. Underlying these claims, multivariate analysis identified two social values. The Societal/Protective highlights counter normative consequences and opposes the use enhancers. The Individual/Proactionary highlights opportunities and supports use. For most respondents these values are not mutually exclusive. This suggests that for many neuroenhancement is viewed simultaneously as a source of both promise and concern. (shrink)

In this paper, we argue that several recent ‘wide’ perspectives on cognition (embodied, embedded, extended, enactive, and distributed) are only partially relevant to the study of cognition. While these wide accounts override traditional methodological individualism, the study of cognition has already progressed beyond these proposed perspectives towards building integrated explanations of the mechanisms involved, including not only internal submechanisms but also interactions with others, groups, cognitive artifacts, and their environment. The claim is substantiated with reference to recent developments in the (...) study of “mindreading” and debates on emotions. We claim that the current practice in cognitive (neuro)science has undergone, in effect, a silent mechanistic revolution, and has turned from initial binary oppositions and abstract proposals towards the integration of wide perspectives with the rest of the cognitive (neuro)sciences.

People sometimes try to call others’ beliefs into question by pointing out the contingent causal origins of those beliefs. The significance of such ‘Etiological Challenges’ is a topic that has started attracting attention in epistemology. Current work on this topic aims to show that Etiological Challenges are, at most, only indirectly epistemically significant, insofar as they bring other generic epistemic considerations to the agent’s attention. Against this approach, we argue that Etiological Challenges are epistemically significant in a more direct and (...) more distinctive way. An Etiological Challenge prompts the agent to assess whether her beliefs result from practices of indoctrination, and whether she should reduce confidence in those beliefs, given the anti-reliability of indoctrination as a method of belief-acquisition. Our analysis also draws attention to some of the ways in which epistemic concerns interact with political issues—e.g. relating to epistemic injustice, identity-based discrimination, and segregation—when we’re thinking about the contingent causal origins of our beliefs.

Some moral theorists argue that being an innocent beneficiary of significant harms inflicted by others may be sufficient to ground special duties to address the hardships suffered by the victims, at least when it is impossible to extract compensation from those who perpetrated the harm. This idea has been applied to climate change in the form of the beneficiary-pays principle. Other philosophers, however, are quite sceptical about beneficiary pays. Our aim in this article is to examine their critiques. We conclude (...) that, while they have made important points, the principle remains worthy of further development and exploration. Our purpose in engaging with these critiques is constructive — we aim to formulate beneficiary pays in ways that would give it a plausible role in allocating the cost of addressing human-induced climate change, while acknowledging that some understandings of the principle would make it unsuitable for this purpose.

In the literature of collective intentions, the ‘we-intentions’ that lie behind cooperative actions are analysed in terms of individual mental states. The core forms of these analyses imply that all Nash equilibrium behaviour is the result of collective intentions, even though not all Nash equilibria are cooperative actions. Unsatisfactorily, the latter cases have to be excluded either by stipulation or by the addition of further, problematic conditions. We contend that the cooperative aspect of collective intentions is not a property of (...) the intentions themselves, but of the mode of reasoning by which they are formed. We analyse collective intentions as the outcome of team reasoning, a mode of practical reasoning used by individuals as members of groups. We describe this mode of reasoning in terms of formal schemata, discuss a range of possible accounts of group agency, and show how existing theories of collective intentions fit into this framework.

Inflicting harm is generally preferable to inflicting death. If you must choose between the two, you should generally choose to harm. But prenatal harm seems different. If a mother must choose between harming her fetus or aborting it, she may choose either, at least in many cases. So it seems that prenatal harm is particularly objectionable, sometimes on a par with death. This paper offers an explanation of why prenatal harm seems particularly objectionable by drawing an analogy to the all-or-nothing (...) problem. It then argues that this analogy offers independent support for the ‘voluntarist’ view that at least some parental role obligations are grounded in the choice to be a parent. (shrink)

Philosophical exploration of individualism and externalism in the cognitive sciences most recently has been focused on general evaluations of these two views (Adams & Aizawa 2008, Rupert 2008, Wilson 2004, Clark 2008). Here we return to broaden an earlier phase of the debate between individualists and externalists about cognition, one that considered in detail particular theories, such as those in developmental psychology (Patterson 1991) and the computational theory of vision (Burge 1986, Segal 1989). Music cognition is an area in the (...) cognitive sciences that has received little attention from philosophers, though it has relatively recently been thrown into the externalist spotlight (Cochrane 2008, Kruger 2014, Kersten forthcoming). Given that individualism can be thought of as a kind of paradigm for research on cognition, we provide a brief overview of the field of music cognition and individualistic tendencies within the field (sections 2 and 3) before turning to consider externalist alternatives to individualistic paradigms (section 4-5) and then arguing for a qualified form of externalism about music cognition (section 6).

I defend the widely-held view that morally worthy action need not be motivated by a desire to promote rightness as such. Some have recently come to reject this view, arguing that desires for rightness as such are necessary for avoiding a certain kind of luck thought incompatible with morally worthy action. I show that those who defend desires for rightness as such on the basis of this argument misunderstand the relationship between moral worth and the kind of luck that their (...) argument employs. Consequently, the argument provides no reason to doubt the popular view that a desire for rightness as such is no part of virtue. I conclude by suggesting that a family of worries about merely accidentally right action presuppose one side of the recent debate about objectivism and perspectivism about moral rightness. (shrink)

This chapter defends the account of metaphysical indeterminacy of Barnes and Williams against Eklund's objections.

While it is tempting to suppose that an act has moral worth just when and because it is motivated by sufficient moral reasons, philosophers have, largely, come to doubt this analysis. Doubt is rooted in two claims. The first is that some facts can motivate a given act in multiple ways, not all of which are consistent with moral worth. The second is the orthodox view that normative reasons are facts. I defend the tempting analysis by proposing and defending a (...) heterodox account of both normative and motivating reasons that is inspired by Donald Davidson’s primary reasons. We should adopt the heterodox view, I argue, because it addresses an overlooked but fatal defect in the orthodox conception of reasons, of which challenges to the tempting analysis are a special case.

In this paper, we consider recent attempts to metaphysically explain agentive modality in terms of conditionals. We suggest that the best recent accounts face counterexamples, and more worryingly, they take some agentive modality for granted. In particular, the ability to perform basic actions features as a primitive in these theories. While it is perfectly acceptable for a semantics of agentive modal claims to take some modality for granted in getting the extension of action claims correct, a metaphysical explanation of agentive (...) modality cannot, at least not in the way that conditional approaches to agentive modality do. We argue that this problem was present even in the classical conditional analysis. By a pessimistic induction, we suggest that, probably, no conditional approach to agentive modality will succeed.

Artificial intelligence (AI) systems have demonstrated impressive performance across a variety of clinical tasks. However, notoriously, sometimes these systems are 'black boxes'. The initial response in the literature was a demand for 'explainable AI'. However, recently, several authors have suggested that making AI more explainable or 'interpretable' is likely to be at the cost of the accuracy of these systems and that prioritising interpretability in medical AI may constitute a 'lethal prejudice'. In this paper, we defend the value of interpretability (...) in the context of the use of AI in medicine. Clinicians may prefer interpretable systems over more accurate black boxes, which in turn is sufficient to give designers of AI reason to prefer more interpretable systems in order to ensure that AI is adopted and its benefits realised. Moreover, clinicians may be justified in this preference. Achieving the downstream benefits from AI is critically dependent on how the outputs of these systems are interpreted by physicians and patients. A preference for the use of highly accurate black box AI systems, over less accurate but more interpretable systems , may itself constitute a form of lethal prejudice that may diminish the benefits of AI to - and perhaps even harm - patients.

While intimately familiar, gender eludes theorizing. We argue that well-known challenges to gender’s analysis originate in a subtle ambiguity: questions about gender sometimes express questions about gender categories themselves (e.g., womanhood, manhood, and so on), while at other times expressing questions about what makes someone a member of these categories. Distinguishing these questions accentuates gender’s connections to morality, making a novel “antirealist” view of gender, or as we call it, “unrealist” view, especially natural. Gender’s relations to identity, sex, and social (...) position are illuminated along the way. Taking cues from both historical and contemporary debates in metaethics about the roles that attitudes can play in metaphysical and semantic analysis, we introduce and begin developing a comprehensive non-ameliorative framework for explicating gender’s nature and our thought and talk about it. In a slogan, on the view we defend, you belong to the gender category to which you intrinsically desire to belong. (shrink)

A general survey of Frege's views on truth, the paper explores the problems in response to which Frege's distinctive view that sentences refer to truth-values develops. It also discusses his view that truth-values are objects and the so-called regress argument for the indefinability of truth. Finally, we consider, very briefly, the question whether Frege was a deflationist.

Throughout his career, Derek Parfit made the bold suggestion, at various times under the heading of the "Normativity Objection," that anyone in possession of normative concepts is in a position to know, on the basis of their competence with such concepts alone, that reductive realism in ethics is not even possible. Despite the prominent role that the Normativity Objection plays in Parfit's non-reductive account of the nature of normativity, when the objection hasn't been ignored, it's been criticized and even derided. (...) We argue that the exclusively negative attention that the objection has received has been a mistake. On our reading, Parfit's Normativity Objection poses a serious threat to reductivism, as it exposes the uneasy relationship between our a priori knowledge of a range of distinctly normative truths and the typical package of semantic commitments that reductivists have embraced since the Kripkean revolution.

MMA fighting in a competition is not necessarily wrong and is often, as far as we can tell, permissible. Our argument has two premises. First, if an act does not infringe on anyone’s moral right or violate another side-constraint, then it is morally permissible. Second, MMA-violence does not infringe on anyone’s moral right or violate another side-constraint. The first premise rested on two assumptions. First, if a person does a wrong act, then he wrongs someone. Second, if one person wrongs (...) a second, then the first infringes on the second’s right. We then looked at Nicholas Dixon’s powerful Kantian argument that MMA fighting is wrong. (shrink)

Matteo Ricci (1552-1610) was an Italian Jesuit and one of the first Christian missionaries to China in the modern era. He was a genuine polymath—a translator, cartographer, mathematician, astronomer, and musician. Above all, Ricci was a missionary for the gospel. As we briefly examine his 1603 seminal work, The True Meaning of the Lord of Heaven, our hope is that we, as evangelical educators, will perceive some of the deeper principles necessary for our own missionary work among unreached people.

I propose and defend a novel view called “de se consequentialism,” which is noteworthy for two reasons. First, it demonstrates—contra Doug Portmore, Mark Schroeder, Campbell Brown, and Michael Smith, among others—that agent-neutral consequentialism is consistent with agent-centered constraints. Second, it clarifies the nature of agent-centered constraints, thereby meriting attention from even dedicated nonconsequentialists. Scrutiny reveals that moral theories in general, whether consequentialist or not, incorporate constraints by assessing states in a first-personal guise. Consequently, de se consequentialism enacts constraints through the (...) very same feature that nonconsequentialist theories do. (shrink)

In this paper, we take a meta-theoretical stance and aim to compare and assess two conceptual frameworks that endeavor to explain phenomenal experience. In particular, we compare Feinberg & Mallatt’s Neurobiological Naturalism (NN) and Tononi’s and colleagues' Integrated Information Theory (IIT), given that the former pointed out some similarities between the two theories (Feinberg & Mallatt 2016c-d). To probe their similarity, we first give a general introduction to both frameworks. Next, we expound a ground plan for carrying out our analysis. (...) We move on to articulate a philosophical profile of NN and IIT, addressing their ontological commitments and epistemological foundations. Finally, we compare the two point-by-point, also discussing how they stand on the issue of artificial consciousness. (shrink)

This book presents a philosophical conception of logic -- "logical expressivism"-- according to which the role of logic is to make explicit reason relations, which are often neither monotonic nor transitive. It reveals new perspectives on inferential roles, sequent calculi, representation, truthmakers, and many extant logical theories.

Objectives: Machine learning (ML) has the potential to facilitate “continual learning” in medicine, in which an ML system continues to evolve in response to exposure to new data over time, even after being deployed in a clinical setting. In this article, we provide a tutorial on the range of ethical issues raised by the use of such “adaptive” ML systems in medicine that have, thus far, been neglected in the literature. -/- Target audience: The target audiences for this tutorial are (...) the developers of ML AI systems, healthcare regulators, the broader medical informatics community, and practicing clinicians. -/- Scope: Discussions of adaptive ML systems to date have overlooked the distinction between 2 sorts of variance that such systems may exhibit—diachronic evolution (change over time) and synchronic variation (difference between cotemporaneous instantiations of the algorithm at different sites)—and underestimated the significance of the latter. We highlight the challenges that diachronic evolution and synchronic variation present for the quality of patient care, informed consent, and equity, and discuss the complex ethical trade-offs involved in the design of such systems.

Fear is a preventer, sometimes robustly so. When fear robustly prevents, it changes or diminishes what an agent is able to do. Various popular conceptions of fear focus on its negative role: fear sometimes prevents us from acting as we should, as in certain cases of akrasia. But by the same token, fear sometimes prevents us from acting as we shouldn’t, as in certain other cases of inverse akrasia. We end with a plea on behalf of fear, both in light (...) of its preventing role and its broader connection to other ways we express concern, in particular, to hope. (shrink)

Seeking to preserve electronically encoded evidence implies that an incident or event has occurred requiring fact extrapolation for presentation, as proof of an irregularity or illegal act.

In large, impersonal moral orders many of us wish to maintain good will toward our fellow citizens only if we are reasonably sure they will maintain good will toward us. The mutual maintaining of good will, then, requires that we somehow communicate our intentions to one another. But how do we actually do this? The current paper argues that when we engage in moral responsibility practices—that is, when we express our reactive attitudes by blaming, praising, and resenting—we communicate a desire (...) to maintain good will to those in the community we are imbedded in. Participating in such practices alone will not get the job done, though, for expressions of our reactive attitudes are often what economists call cheap talk. But when we praise and blame in cases of moral diversity, expressions of our reactive attitudes act as costly signals capable of solving our social dilemma. (shrink)

Competitive negotiators frequently use tactics which others view as "unethical", in that these tactics either violate standards of truth telling or violate the perceived rules of negotiation. This paper sought to determine how business students viewed a number of marginally ethical negotiating tactics, and to determine the underlying factor structure of these tactics. The factor analysis of these tactics revealed five clear factors which were highly similar across the two samples, and which parallel (to a moderate degree) categories of tactics (...) proposed by earlier theory. Data from one sample also permitted comparisons of the appropriateness of certain tactics across gender, nationality, ethnic origin and perception of one's negotiating style. (shrink)

Communicative practices in online and social media sometimes seem to amplify political conflict, and result in significant harms to people who become the targets of collective outrage. Many complaints that have been made about political correctness in the past, we argue, amount to little more than a veiled expression of resentment over the increasing influence enjoyed by progressive activists. But some complaints about political correctness take on a different complexion, in light of the technologically-driven changes to our communicative practices and (...) political discourse. Given the ways in which they are entangled in these new forms of online communication, well-meaning attempts to police the norms of political correctness may end up contributing to individual wrongs, or to destructive social patterns. In this paper we examine these worries, situate them in a broader sociological context, and offer some tentative proposals about how they might be addressed. (shrink)

In this paper, we propose a mathematical model of subjective experience in terms of classes of hierarchical geometries of representations (“n-awareness”). We first outline a general framework by recalling concepts from higher category theory, homotopy theory, and the theory of (infinity,1)-topoi. We then state three conjectures that enrich this framework. We first propose that the (infinity,1)-category of a geometric structure known as perfectoid diamond is an (infinity,1)-topos. In order to construct a topology on the (infinity,1)-category of diamonds we then propose (...) that topological localization, in the sense of Grothendieck-Rezk-Lurie (infinity,1)-topoi, extends to the (infinity,1)-category of diamonds. We provide a small-scale model using triangulated categories. Finally, our meta-model takes the form of Efimov K-theory of the (infinity,1)-category of perfectoid diamonds, which illustrates structural equivalences between the category of diamonds and subjective experience (i.e.its privacy, self-containedness, and self-reflexivity). Based on this, we investigate implications of the model. We posit a grammar (“n-declension”) for a novel language to express n-awareness, accompanied by a new temporal scheme (“n-time”). Our framework allows us to revisit old problems in the philosophy of time: how is change possible and what do we mean by simultaneity and coincidence? We also examine the notion of “self” within our framework. A new model of personal identity is introduced which resembles a categorical version of the “bundle theory”: selves are not substances in which properties inhere but (weakly) persistent moduli spaces in the K-theory of perfectoid diamonds.

Philosophers have recently come to focus on explaining the phenomenon of ​bad beliefs,​ beliefs that are apparently true and well-evidenced but nevertheless objectionable. Despite this recent focus, a consensus is already forming around a particular explanation of these beliefs’ badness called ​moral encroachment​, according to which, roughly, the moral stakes engendered by bad beliefs make them particularly difficult to justify. This paper advances an alternative account not just of bad beliefs but of bad attitudes more generally according to which bad (...) beliefs’ badness originates not in a failure of sufficient evidence but in a failure to respond adequately to reasons. I motivate this alternative account through an analogy to recent discussions of moral worth centered on the well-known grocer case from Kant’s ​Groundwork​, and by showing that this analogy permits the proposed account to generalize to bad attitudes beyond belief. The paper concludes by contrasting the implications of moral encroachment and of the proposed account for bad attitudes’ blameworthiness. (shrink)

How do archaeologists make effective use of physical traces and material culture as repositories of evidence? Material Evidence is a collection of 19 essays that take a resolutely case-based approach to this question, exploring key instances of exemplary practice, instructive failures, and innovative developments in the use of archaeological data as evidence. The goal is to bring to the surface the wisdom of practice, teasing out norms of archaeological reasoning from evidence. -/- Archaeologists make compelling use of an enormously diverse (...) range of material evidence, from garbage dumps to monuments, from finely crafted artifacts rich with cultural significance to the inadvertent transformation of landscapes over the long term. Each contributor to Material Evidence identifies a particular type of evidence with which they grapple and considers, with reference to concrete examples, how archaeologists construct evidential claims, critically assess them, and bring them to bear on pivotal questions about the cultural past. -/- Historians, cultural anthropologists, philosophers, and science studies scholars are increasingly interested in working with material "things" as objects of inquiry and as evidence – and they acknowledge on all sides just how challenging this is. One of the central messages of the book is that close analysis of archaeological best practice can yield constructive guidelines for practice that have much to offer practitioners within archaeology and well beyond.

An investigation of what Frege means by his doctrine that functions (and so concepts) are 'unsaturated'. We argue that this doctrine is far less peculiar than it is usually taken to be. What makes it hard to understand, oddly enough, is the fact that it is so deeply embedded in our contemporary understanding of logic and language. To see this, we look at how it emerges out of Frege's confrontation with the Booleans and how it expresses a fundamental difference between (...) Frege's approach to logic and theirs. (shrink)

This article offers a comprehensive and critical analysis of Eric Heinze’s book Hate Speech and Democratic Citizenship (Oxford University Press, 2016). Heinze’s project is to formulate and defend a more theoretically complex version of the idea (also defended by people like Ronald Dworkin and James Weinstein) that general legal prohibitions on hate speech in public discourse compromises the state’s democratic legitimacy. We offer a detailed synopsis of Heinze’s view, highlighting some of its distinctive qualities and strengths. We then develop a (...) critical response to this view with three main focal points: (1) the characterisation of democratic legitimacy as something distinct from (and whose demands aren’t identical with those of) legitimacy per se; (2) the claim that the requirements of democracy are hypothetical, rather than categorical, imperatives; and relatedly (3) the question of how we should reconcile the requirements of democratic legitimacy with the costs that may follow from prioritising democratic legitimacy. We argue that there are significant difficulties for Heinze’s account on all three fronts. (shrink)

Literature reviews have traditionally been a simple exercise in reporting the current relevant research, both to provide an overview of the current status of the field, and perhaps to draw attention to controversies. From the perspective of positivist research traditions, it was important to neutrally report all the relevant research, which was assumed to be foundational. In this article, written for the Applied Critical Realism special issue of Journal of Critical Realism, I use my own research to illustrate how a (...) literature review might look if it were non-foundational and guided by the principles of immanent critique. Immanent critique is central to Bhaskar’s philosophical methodology but has not been much applied in critical realist empirical research. Following a brief introduction to immanent critique, its history and relation to other ways of grounding knowledge, an excerpt from a literature review is used as backdrop for an extended discussion about various potential applications, and impl...

Louis Pojman and Robert Westmoreland have compiled the best material on the subject of equality, ranging from classical works by Aristotle, Hobbes and Rousseau to contemporary works by John Rawls, Thomas Nagel, Michael Walzer, Harry Frankfurt, Bernard Williams and Robert Nozick; and including such topics as: the concept of equality; equal opportunity; Welfare egalitarianism; resources; equal human rights and complex equality.

People sometimes use speech to interfere with other people’s speech, as in the case of a heckler sabotaging a lecture with constant interjections. Some people claim that such interference infringes upon free speech. Against this view, we argue that where competing speakers in a public forum both have an interest in speaking, free speech principles should not automatically give priority to the ‘official’ speaker. Given the ideals underlying free speech, heckling speech sometimes deserves priority. But what can we say, then, (...) about situations in which heckling clearly seems to infringe upon people’s civil liberties, in a way that intuitively justifies intervention? In such cases, we argue, heckling infringes upon people’s associative freedom. We present and defend an ethical framework for the institutional management of ‘Speech Fights’, geared around this insight. (shrink)

The VIA Classification of Strengths and Virtues is the most commonly used model of positive personality. In this study, we used two methods of model modification to develop models for two measures of the character strengths, the VIA Inventory of Strengths-Revised and the Global Assessment of Character Strengths. The first method consisted of freeing residual covariances based on modification indices until good fit was achieved. The second was residual network modeling (RNM), which frees residual partial correlations while minimizing a function (...) that penalizes more complex models. Models based on both strategies were developed for the two questionnaires. The resulting structural models were then applied to four other samples. Though both modification procedures achieved good fit in the sample used to develop the models, only RNM resulted in adequate model fit for both measures in all cross-validation samples. This finding suggests RNM is more robust against overfitting than traditional practices. Moreover, the result supports the validity of the three-factor model of character strengths with replicability. (shrink)

The automation of online social life is an urgent issue for researchers and the public alike. However, one of the most significant uses of such technologies seems to have gone largely unnoticed by the research community: religion. Focusing on Islamic Prayer Apps, which automatically post prayers from its users’ accounts, we show that even one such service is already responsible for millions of tweets daily, constituting a significant portion of Arabic-language Twitter traffic. We argue that the fact that a phenomenon (...) of these proportions has gone unnoticed by researchers reveals an opportunity to broaden the scope of the current research agenda on online automation.

Artificial intelligence (AI) systems have demonstrated impressive performance across a variety of clinical tasks. However, notoriously, sometimes these systems are “black boxes.” The initial response in the literature was a demand for “explainable AI.” However, recently, several authors have suggested that making AI more explainable or “interpretable” is likely to be at the cost of the accuracy of these systems and that prioritizing interpretability in medical AI may constitute a “lethal prejudice.” In this paper, we defend the value of interpretability (...) in the context of the use of AI in medicine. Clinicians may prefer interpretable systems over more accurate black boxes, which in turn is sufficient to give designers of AI reason to prefer more interpretable systems in order to ensure that AI is adopted and its benefits realized. Moreover, clinicians may be justified in this preference. Achieving the downstream benefits from AI is critically dependent on how the outputs of these systems are interpreted by physicians and patients. A preference for the use of highly accurate black box AI systems, over less accurate but more interpretable systems, may itself constitute a form of lethal prejudice that may diminish the benefits of AI to—and perhaps even harm—patients.

In the De Anima, Aristotle claims that the five senses are infallible about their proper objects. I contend that this claim means that sight is infallible about its proper object in its most specific form, i. e. sight is infallible about red or green and not merely about color in general. This robust claim is justified by Aristotle’s teleological principle that nature does nothing in vain. Additionally, drawing on Aristotle’s comparison of perception and one’s understanding of the essences, I defend (...) a conception of the senses in which the structure of their contents is simple rather than predicative and show how this coheres better with the rest of my interpretation.

We can use radically different reference‐schemes to generate the same truth‐conditions for the sentences of a language. In this paper, we do three things. (1) Distinguish two arguments that deploy this observation to derive different conclusions. The first argues that reference is radically indeterminate: there is no fact of the matter what ordinary terms refer to. This threat is taken seriously and most contemporary metasemantic theories come with resources intended to rebut it. The second argues for radical parochialism about reference: (...) it's a reflection of our parochial interests, rather than the nature of the subject matter, that our theorizing about language appeals to reference rather than another relation that generates the same truth‐conditions. Rebuttals of the first argument cut no ice against the second, because radical parochialism is compatible with reference being determinate. (2) Argue that radical parochialism, like radical indeterminacy, would be shocking if true. (3) Argue that the case for radical parochialism turns on the explanatory purposes of “reference”‐talk: on relatively “thin” conceptions, the argument goes through, and radical parochialism is (shockingly!) true; on richer conceptions, the argument can be blocked. We conclude that non‐revisionists must endorse, and justify, a relatively rich conception of the explanatory purposes of “reference”‐talk. (shrink)

D. M. Armstrong famously claims that deterministic laws of nature are contingent relations between universals and that his account can also be straightforwardly extended to irreducibly probabilistic laws of nature. For the most part, philosophers have neglected to scrutinize Armstrong’s account of probabilistic laws. This is surprising precisely because his own claims about probabilistic laws make it unclear just what he takes them to be. We offer three interpretations of what Armstrong-style probabilistic laws are, and argue that all three interpretations (...) are incompatible either with some feature of Armstrong’s broader metaphysics or with essential features of his account of laws (or both).

Inspired by the practice of dialogue in ancient philosophical schools, the Philosophy as a Way of Life (PWOL) Project at the University of Notre Dame has sought to put dialogue back at the center of philosophical pedagogy. Impromptu philosophical dialogue, however, can be challenging for students who are new to philosophy. Anticipating this challenge, the Project has created a series of manuals to help instructors conduct dialogue groups with novice philosophy students. Using these guidelines, we incorporated PWOL-style dialogue groups into (...) our Spring 2021 course “The Philosophy of Race, Class, and Gender” with the hope that, through having conversations about these challenging topics, our students would both be able to practice having philosophical dialogues as well as form their views on race and gender in light of contributions from their diverse peers. This article examines several strategies for how instructors can seek to incorporate similar dialogues into their own introductory classroom. (shrink)
