The dominant framework for addressing procreative ethics has revolved around the notion of harm, largely due to Derek Parfit’s famous non-identity problem. Focusing exclusively on the question of harm treats what procreators owe their offspring as akin to what they would owe strangers (if they owe them anything at all). Procreators, however, usually expect (and are expected) to parent the persons they create, so we cannot understand what procreators owe their offspring without also appealing to their role as prospective parents. (...) I argue that prospective parents can wrong their future children just by failing to act well in their role as parents, whether or not their offspring are ultimately harmed or benefitted by their creation. Their obligations as prospective parents bear on the motivations behind their reproductive choices, including the choice to select for some genetic trait in their offspring. Even when procreators’ motivations aren’t malicious, or purely selfish, they can still fail to recognize and act for the end of the parental role. Procreators can wrong their offspring by selecting for some genetic trait, then, when doing so would violate their obligations as prospective parents, or when their motivation for doing so is antithetical to the end of the parental role.

Many accounts of the morality of abortion assume that early fetuses must all have or lack moral status in virtue of developmental features that they share. Our actual attitudes toward early fetuses don’t reflect this all-or-nothing assumption: early fetuses can elicit feelings of joy, love, indifference, or distress. If we start with the assumption that our attitudes toward fetuses reflect a real difference in their moral status, then we need an account of fetal moral status that can explain that difference. (...) I argue that we can have or lack relational obligations to early fetuses in light of our own activities or choices, independent of the fetus’s own features or properties. Those relational obligations make the early fetus morally considerable to the persons who stand in a moral relation to it. Pregnant persons (and other participants in the procreative process) can come to have relational obligations to an early fetus just in virtue of their own decision to create a person, either by intentionally getting pregnant or by deciding to continue a pregnancy. That decision not only makes it appropriate for them to care about the fetus, but it also generates obligations to the fetus that they didn’t have before that decision. (shrink)

For many women experiencing motherhood for the first time, the message they receive is clear: mothers who do not breastfeed ought to have good reasons not to; bottle feeding by choice is a failure of maternal duty. We argue that this pressure to breastfeed arises in part from two misconceptions about maternal duty: confusion about the scope of the duty to benefit and conflation between moral reasons and duties. While mothers have a general duty to benefit, we argue that this (...) does not imply a duty to carry out any particular beneficent act. Therefore, the expectation that mothers should breastfeed unless they have sufficient countervailing reasons not to is morally unwarranted. Recognising the difference between reasons and duties can allow us to discuss the benefits of breastfeeding and the importance of supporting mothers who wish to breastfeed without subjecting mothers who bottle feed to guilt, blame and failure.

Population obesity and associated morbidities pose significant public health and economic burdens in the United Kingdom, United States, and globally. As a response, public health initiatives often seek to change individuals’ unhealthy behavior, with the dual aims of improving their health and conserving health care resources. One such initiative—taxes on sugar‐sweetened beverages (SSB)—has sparked considerable ethical debate. Prominent in the debate are arguments seeking to demonstrate the supposed impermissibility of SSB taxes and similar policies on the grounds that they interfere (...) with individuals’ freedom and autonomy. Commentators have often assumed that a policy intended to restrict or change private individuals’ consumption behavior will necessarily curtail freedom and, as a corollary, will undermine individuals’ autonomy with respect to their consumption choices. Yet this assumption involves a conceptual mistake. To address the misunderstanding, it’s necessary to attend to the differences between negative liberty, freedom of options, and autonomy. Ultimately, concerns about negative liberty, freedom, and autonomy do not provide strong grounds for opposing SSB taxes. (shrink)

Reasoning about analogical arguments is known to be subject to a variety of cognitive biases, and a lack of clarity about which factors can be considered strengths or weaknesses of an analogical argument. This can make it difficult both to design empirical experiments to study how people reason about analogical arguments, and to develop scalable tutoring tools for teaching how to reason and analyze analogical arguments. To address these concerns, we describe WG-A (Warrant Game — Analogy), a framework for people (...) to analyze analogical arguments based on Bartha’s (2010) Articulation Model of analogical argumentation. We carry out two experiments designed to probe WG-A’s effectiveness in improving participants’ ability to reason about analogical arguments and argumentation in general, and argue that WG-A is a promising approach, though it is in need of further development.

This paper examines the practice of using predictive systems to lengthen the prison sentences of convicted persons when the systems forecast a higher likelihood of re-offense or re-arrest. There has been much critical discussion of technologies used for sentencing, including questions of bias and opacity. However, there hasn’t been a discussion of whether this use of predictive systems makes sense in the first place. We argue that it does not by showing that there is no plausible theory of punishment that (...) supports it. (shrink)

In this article, I examine the moral dimensions of gender affirmation. I argue that the moral value of gender affirmation is rooted in what Iris Murdoch called loving attention. Loving attention is central to the moral value of gender affirmation because such affirmation is otherwise too fragile or insincere to have such value. Moral reasons to engage in acts that gender affirm derive from the commitment to give and express loving attention to trans people as a way of challenging their (...) marginalization. In the latter part of the paper, I will discuss how my arguments bear on recent arguments by Robin Dembroff and Daniel Wodak (2018) on the use of gender-neutral language. They argue that we have a duty not to use gender-specific pronouns for anyone. Their conclusion turns, in part, on a rejection of gender affirmation as a moral duty. The value of gender affirmation, rooted in our moral perception of trans people, should make us skeptical of this conclusion, in favor of a more nuanced and pluralistic approach to the ethics of gendering.

The scientific community, we hold, often provides society with knowledge—that the HIV virus causes AIDS, that anthropogenic climate change is underway, that the MMR vaccine is safe. Some deny that we have this knowledge, however, and work to undermine it in others. It has been common to refer to such agents as “denialists”. At first glance, then, denialism appears to be a form of skepticism. But while we know that various denialist strategies for suppressing belief are generally effective, little is (...) known about which strategies are most effective. We see this as an important first step toward their remediation. This paper leverages the approximate comparison to various forms of philosophical skepticism to design an experimental test of the efficacy of four broad strategies of denial at suppressing belief in specific scientific claims. Our results suggest that assertive strategies are more effective at suppressing belief than questioning strategies. (shrink)

The role of imagination in Descartes. The critic of Sartre to the concept of image in Descartes.

Wittgenstein’s concepts shed light on the phenomenon of schizophrenia in at least three different ways: with a view to empathy, scientific explanation, or philosophical clarification. I consider two different “positive” wittgensteinian accounts―Campbell’s idea that delusions involve a mechanism of which different framework propositions are parts, Sass’ proposal that the schizophrenic patient can be described as a solipsist, and a Rhodes’ and Gipp’s account, where epistemic aspects of schizophrenia are explained as failures in the ordinary background of certainties. I argue that (...) none of them amounts to empathic-phenomenological understanding, but they provide examples of how philosophical concepts can contribute to scientific explanation, and to philosophical clarification respectively.

Objective: Compassion has been associated with eudaimonia and prosocial behavior, and has been regarded as a virtue, both historically and cross-culturally. However, the psychological study of compassion has been limited to laboratory settings and/or standard survey assessments. Here, we use an experience sampling method (ESM) to compare naturalistic assessments of compassion with standard assessments, and to examine compassion, its variability, and associations with eudaimonia and prosocial behavior. -/- Methods: Participants took a survey which included standard assessments of compassion and eudaimonia. (...) Then, over four days, they were repeatedly asked about their level of compassion, eudaimonia, and situational factors within the moments of daily life. Finally, prosocial behavior was tested using the Dual Gamble Task and an opportunity to donate task winnings. -/- Results: Analyses revealed within-person associations between ESM compassion and eudaimonia. ESM compassion also predicted eudaimonia at the next ESM time point. While not impervious to situational factors, considerable consistency was observed in ESM compassion in comparison with eudaimonia. Further, ESM compassion along with eudaimonia predicted donating behavior. Standard assessments did not. -/- Conclusion: Consistent with virtue theory, some individual’s reports displayed a probabilistic tendency toward compassion, and ESM compassion predicted ESM eudaimonia and prosocial behavior toward those in need.

This chapter describes the potential far‐reaching consequences of contemplative higher education for the fields of science and medicine.

Although there is increasing recognition that theory and practice in science are often inseparably intertwined, discussions of scientific controversies often continue to focus on theory, and not practice or methodologies. As a contribution to constructing a framework towards understanding controversies linked to scientific practices, we introduce the notion of borrowed epistemic credibility, to describe the situation in which scientists exploit fallacious similarities between accepted tenets in other fields to garner support for a given position in their own field. Our proposal (...) is based on the analysis of a recent controversy in phylogeography, a biological subdiscipline concerned with the study of the historical causes of variation in genetic diversity within species in concrete biogeographical locations. Through a review of the arguments that support the two conflicting phylogeographic schools, we show that ‘theory’ plays essentially no role as a foundation of the controversy, whereas both sides borrow epistemic credibility from sources such as formal logic, similarity of results to those in other scientific areas, the authority of prominent scientists, or the presumed superiority of quantitative vs. verbal reasoning. Our case study underscores the indivisibility of theory and practice and provide a means to re-examine important philosophical issues such as the meaning of inference, rationality, justification, and objectivity in scientific practice.

The as-structure provided by language, even in the sciences, is always constitutive of experience and never merely designative. “From Saying…it comes to pass that the World is made to appear” (Heidegger 1971 [1957]: 101).

In a reflective and richly entertaining piece from 1979, Doug Hofstadter playfully imagined a conversation between ‘Achilles’ and an anthill (the eponymous ‘Aunt Hillary’), in which he famously explored many ideas and themes related to cognition and consciousness. For Hofstadter, the anthill is able to carry on a conversation because the ants that compose it play roughly the same role that neurons play in human languaging; unfortunately, Hofstadter’s work is notably short on detail suggesting how this magic might be achieved1. (...) Conversely in this paper - finally reifying Hofstadter’s imagination - we demonstrate how populations of simple ant-like creatures can be organised to solve complex problems; problems that involve the use of forward planning and strategy. Specifically we will demonstrate that populations of such creatures can be configured to play a strategically strong - though tactically weak - game of HeX (a complex strategic game).We subsequently demonstrate how tactical play can be improved by introducing a form of forward planning instantiated via multiple populations of agents; a technique that can be compared to the dynamics of interacting populations of social insects via the concept of meta-population. In this way although, pace Hofstadter, we do not establish that a meta-population of ants could actually hold a conversation with Achilles, we do successfully introduce Aunt Hillary to the complex, seductive charms of HeX.

Resumo: A crise na União Europeia e os programas de austeridade subsequentes fizeram emergir uma miríade de movimentos sociais, diversos na sua natureza e nos seus propósitos. O que se pretende aferir neste artigo é a relação e a conexão existentes entre o Estado, o poder económico, a sociedade civil e os movimentos sociais neste contexto específico de crise. Procuraremos, nesta breve abordagem, explanar alguns elementos de originalidade intrínsecos aos movimentos sociais hodiernos, patentes na sua forma de participação e organização, (...) assim como aplicar estas questões teóricas relevantes ao contexto português. A parte empírica, dada a escassez de estudos de caso existentes, será apoiada no último inquérito do European Social Survey, de 2012. Analisando um conjunto de perguntas aí explícitas, podemos compreender, de forma indirecta, algumas das dinâmicas que caracterizam estes movimentos.

We will try, in this brief approach, to explain some elements of originality intrinsic to modern social movements, evident in their form of participation and organization, as well as to apply these theoretical questions relevant to the Portuguese context. The empirical part, given the paucity of existing case studies, will be supported in the last survey of the European Social Survey of 2012. By analyzing a set of questions explicit there, we can, indirectly, understand some of the dynamics that characterize these movements. (shrink)

Conceptualism is the view that at least some perceptual representation is conceptual. This paper considers a prominent recent argument against Conceptualism due to Ned Block. Block’s argument appeals to patterns of color representation in infants, alleging that infants exhibit categorical perception of color while failing to deploy concepts of color categories. Accordingly, the perceptual representation of color categories in infancy must be non-conceptual. This argument is distinctive insofar as it threatens not only the view that all perception is conceptual, but (...) also views that restrict the Conceptualist thesis to perceptual categorization. However, I contend that it fails at two stages. Block’s arguments for the perceptual representation of color categories in infancy, and against color concept deployment in infancy, are unpersuasive. Thus, Block has not vanquished Conceptualism. I draw out implications for debates about the perception-cognition border and for the question of whether explicit categorization occurs in perception.

Logical realism is a view about the metaphysical status of logic. Common to most if not all the views captured by the label ‘logical realism’ is that logical facts are mind- and language-independent. But that does not tell us anything about the nature of logical facts or about our epistemic access to them. The goal of this paper is to outline and systematize the different ways that logical realism could be entertained and to examine some of the challenges that these (...) views face. It will be suggested that logical realism is best understood as a metaphysical view about the logical structure of the world, but this raises an important question: does logical realism collapse into standard metaphysical realism? It will be argued that this result can be accommodated, even if it cannot be altogether avoided. (shrink)

De uma perspectiva comportamentalista radical, o eu é um repertório verbal complexo, que, como tal, tem uma gênese social. O reconhecimento da origem social do “eu” abre caminho para uma análise política, incluindo uma discussão do pa- pel das relações de poder na constituição do eu. Entretanto, uma concepção radicalmente social do “eu”, como a proposta pelo comportamentalismo, suscita um problema político: se o eu é integralmente produto do ambiente social, de onde viria uma eventual “vontade” de romper com esse (...) sistema? Parece que para reconhecer a possibilidade de ação política transformadora seria preciso preservar uma noção descontextualizada de “eu”. Considerando essa dificuldade, o objetivo deste artigo é propor uma interpretação política da constituição do “eu” no âmbito do comportamentalismo radical, mantendo no horizonte a possibilidade de uma ação política transformadora. Para tanto, destacamos como “eus” oprimidos são tornados submissos, mas também como de certas contingências podem emergir “eus” subversivos, que se opõem a um sistema social opressivo. Esse “eu” subversivo é caracterizado por um repertório de autoconhecimento mais amplo, que inclui a discriminação do papel das relações de poder e do controle promovido por instituições. Concluímos, com isso, que um “eu” socialmente constituído pode ser politicamente ativo. (shrink)

Abstract: Alienation and slavery from Precious or what we don't want to see. It is our purpose to establish, in a parallel reading, these two films (highly rewarded), namely The Fence and Precious, that apparently being so different, are an illustration of the reality of life and the modern democratic world: the social uprooting and slavery. If in the movie of Phillip Noyce and Christone Olsen The Fence, is told a story of three young Aboriginal girls who are forcibly taken (...) to be transformed into domestic slaves, in the movie of Lee Daniels Precious, the young woman is already a servant in her own home and seeks the transformation of her life. Uniting these two stories, we find fundamental elements: illiteracy, ill-treatment, the idea of a migration (real or metaphysical), among others, but whose fundamental notion is the journey. If the film The Fence, the fence itself is used to conduct the three young Aboriginal to a real reunion with the family, in Precious, the metaphorical ‘fence’ is the limit of her world. From this interpretation, we will undertake our reflection about what we consider to be the alienation of the modern world and the silence we produce about them. (shrink)

Shedding light on the political power and oppressive potential of language, theories of illocutionary silencing and discursive injustice show how gender, class and race can shape the pragmatics of speech, limiting in some circumstances the speaker’s ability to do things with her words. This article takes a close look at discursive injustice in trials for gender-based violence in connection with the phenomenon of misogyny. It argues that in the courtroom the testimony of the complainant is sometimes silenced by a sexist (...) ideology used in service of misogynistic ends. In particular, it argues that sexist social meanings can sometimes be enacted by the judge and accommodated by prosecutors, figuring as a component of the score in the language game of the trial and thus 1) determining what counts as sexual violence and 2) preventing complainants from making the moves they intend to make.

O presente artigo pretende abordar o conceito de trágico, entendido como elemento principal ou elemento orquestrador do projecto nietzschiano em busca de uma determinação para uma nova forma de existência estética. Objectivo do autor é, pois, em primeiro lugar, explicitar o sentido da nova existência estética tal como Nietzsche, pela mão de Zaratustra, imputa à figura do Übermensch, o qual estabelece um projecto de justificação estética; em segundo lugar, trata-se de mostrar que o conceito de 'trágico'está estreitamente relacionado com o (...) conceito metafísico de 'eterno retorno'de tal modo que isso pretende, por um lado, ultrapassar a dimensão determinada da vida humana em algo maior ou melhor, e, por outro, visa a completa realização da vida humana que pode ser repetida, salientando que este movimento de repetição afirma o retorno dionisíaco do trágico. Objectivo do autor do artigo é, assim, provar que o projecto nietzschiano anuncia o Übermensch como uma nova forma de existência estética, ao mesmo tempo que recupera os conceitos de 'trágico' e 'dionisíaco', conceitos estes que animam a obra Die Geburt der Tragödie. Consequentemente, trata-se de ver até que ponto o Übermensch está afirmado como objectivo necessário e primário neste projecto, o qual permanece, contudo, uma herança enigmática em que nos deixa a filosofia de Nietzsche. /// The present article presents a brief approach to the concept of the 'tragic' understood as a main element or a conducting element in the Nietzschean project that searches for a determination of a new form of aesthetic existence. The author aims, thus, at two things: first, to explicit the meaning of this new aesthetic existence that Nietzsche, by the hand of Zarathustra, imputes to the figure of the Übermensch, which establishes a project of aesthetic justification; secondly, to show that the concept of the 'tragic' is closely related to the metaphysical concept of the 'eternal return' in such a way that it purposes, on the one hand, to surpass a determined dimension of human life into something bigger or better, and, on the other, to bring about a complete realisation of human life that can be repeated, so that the movement of repetition qffirms the dionysiac return of the tragic. The goal of the article is, moreover, to prove that the Nietzschean project announces the Übermensch as a new form of aesthetic existence while recovering the main concepts of 'tragic' and 'dionysiac', concepts that animate the book Die Geburt der Tragödie. Therefore, we shall see how the Ubermensch is placed as a necessary and prime objective in this project, which remains part of the enigmatic legacy with which Nietzsche's philosophy leaves us.

This article develops a view of shape representation both in visual experience and in subpersonal visual processing. The view is that, in both cases, shape is represented in a ‘layered’ manner: an object is represented as having multiple shape properties, and these properties have varying degrees of abstraction. I argue that this view is supported both by the facts about visual phenomenology and by a large collection of evidence in perceptual psychology. Such evidence is provided by studies of shape discriminability, (...) apparent motion, multiple-object tracking, and structure-from-motion. Recent neuroscientific work has also corroborated this psychophysical evidence. Finally, I draw out implications of the layered view for processes of concept acquisition. 1 Introduction2 Metric Properties andShape Properties3 Metric Views4 Against Metric Views of Visual Shape Experience5 The Visual System Uses Abstract Shape Properties6 Against Metric Views of Visual Shape Representation7 Neural Underpinnings of Abstract Shape Perception8 Implications.

Abstract. Following the tracks of Ryle and based upon the theory of complex systems, we shall develop a characterization of action-based consciousness as an embodied, embedded, selforganized process in which action and dispositions occupy a special place. From this perspective, consciousness is not a unique prerogative of humans, but it is spread all around, throughout the evolution of life. We argue that artificial systems such as robots currently lack the genuine embodied embeddedness that allows the type of self-organization that is (...) relevant to consciousness. -/- Sommario. Seguendo la linea tracciata da Ryle e basata sulla teorie dei sistemi complessi, svilupperemo una caratterizzazione della coscienza basata sull’azione come un processo incarnato, situato e auto organizzante nel quale le azioni e le disposizioni occupano un ruolo decisivo. Da questo punto di vista, la coscienza non è una prerogativa esclusiva degli esseri umani, ma è diffusa nel mondo naturale grazie ai processi evolutivi. Noi sosteniamo che i sistemi artificiali come i robot attualmente sono carenti del tipo di relazione con la corporeità e con l’ambiente che consente quel tipo di auto-organizzazione indispensabile per l’emergenza della coscienza.

The ability to perceive the shapes of things as enduring through changes in how they stimulate our sense organs is vital to our sense of stability in the world. But what sort of capacity is shape constancy, and how is it reflected in perceptual experience? This paper defends a pluralist account of shape constancy: There are multiple kinds of shape constancy centered on geometrical properties at various levels of abstraction, and properties at these various levels feature in the content of (...) perceptual experience, governing patterns of apparent shape similarity. I propose that the varieties of shape constancy are subserved by the syntactic complexity of perceptual shape representations. By assigning discrete constituents to various abstract shape parameters, these representations attune us to the preservation of certain abstract shape properties through changes in more determinate shape properties. Finally, I draw broader lessons concerning the nature and function of perceptual constancy. (shrink)

When we perceive an object, we perceive the object from a perspective. As a consequence of the perspectival nature of perception, when we perceive, say, a circular coin from different angles, there is a respect in which the coin looks circular throughout, but also a respect in which the coin's appearance changes. More generally, perception of shape and size properties has both a constant aspect—an aspect that remains stable across changes in perspective—and a perspectival aspect—an aspect that changes depending on (...) one's perspective on the object. How should we account for the perspectival aspect of spatial perception? We present a framework within which to discuss the perspectival aspect of perception and put forward three desiderata that any account of the perspectival aspect of perception should satisfy. We discuss views on which the perspectival aspect of perception is analyzed in terms of constitutively mind-dependent appearance properties as well as views on which the perspectival aspect of perception is analyzed in terms of representations of mind-independent perspectival properties.

A pecuária brasileira tem destaque acentuado quanto a sua participação no produto interno Bruto nacional (PIB), entretanto, dentro da cadeia produtiva das proteínas de origem animal, a ovinocultura ainda se apresenta como uma atividade com pouca expressividade e tecnificação frente a outras espécies animais domésticas, desta forma seu fomento e próspero desenvolvimento é dependente de inúmeros fatores, sendo que destes o correto manejo reprodutivo de espécies , a escolha de raças autóctones ou do exterior com boa adaptabilidade para serem criadas (...) em regiões de clima tropical e subtropical encontrados no Brasil e a correta seleção quanto a características reprodutivas de matrizes e principalmente de jovens carneiros cujos quais se deseja utilizar como reprodutores em rebanhos que buscam a constante evolução produtiva se faz muito importante. Tal cenário traz à tona a importância da realização de estudos referentes a suplementação de elementos como vitaminas e microminerais, que embora não sejam os maiores constituintes das dietas ofertadas aos animais de interesse zootécnico, exercem grande influência não só no crescimento e desenvolvimento do tecido muscular como também podem estar positivamente correlacionados quanto aos aspectos reprodutivos . O presente trabalho objetivou a avaliação da qualidade seminal e morfometria testicular de carneiros púberes submetidos a suplementação injetável de minerais e vitaminas, sendo utilizados 30 reprodutores divididos em três grupos de dez animais cada, com delineamento dos grupos inteiramente casualizado.

Palavras chave: elementos-traço, hormônios, nutracêutico, ovinos, sêmen -/- Brazilian livestock has a strong emphasis in terms of its participation in the Gross National Product (GDP), however, within the production chain of animal proteins, sheep farming still presents itself as an activity with little expressiveness and technology compared to other domestic animal species. in this way its promotion and development depends on the correct methods, which are the reproductive of sheep species, the choice of indigenous or foreign breeds with good adaptability to be created in tropical and subtropical regions found in Brazil and the correct selection of selected animals and selection of products that are very important for the demand for products of constant breeding. This scenario leads to the development of important studies for the supplementation of such vitamins and trace minerals, which, although not the largest components of diets, exert a great influence not only on the growth of muscle tissues but can also be positively correlated with their reproductive aspects. The present evaluation of seminal quality and testicular morphometric of pubertal animals includes an injectable supplement of vitamins and minerals, using 30 sires distributed in three groups of animals each, with a completely random design of the products. The first supplementary group was given the mineral supplement (VM Group) in the second group only vitamin supplementation (VM Group) and the mineral supplementation group (MIN Group).

There is a widespread belief that for their own safety and for the protection of wildlife, cats should be permanently kept indoors. Against this view, I argue that cat guardians have a duty to provide their feline companions with outdoor access. The argument is based on a sophisticated hedonistic account of animal well-being that acknowledges that the performance of species-normal ethological behavior is especially pleasurable. Territorial behavior, which requires outdoor access, is a feline-normal ethological behavior, so when a cat is (...) permanently confined to the indoors, her ability to flourish is impaired. Since cat guardians have a duty not to impair the well-being of their cats, the impairment of cat flourishing via confinement signifies a moral failing. Although some cats assume significant risks and sometimes kill wild animals when roaming outdoors, these important considerations do not imply that all cats should be deprived of the opportunity to access the outdoors. Indeed, they do not, by themselves, imply that any cat should be permanently kept indoors. (shrink)

Marr’s seminal distinction between computational, algorithmic, and implementational levels of analysis has inspired research in cognitive science for more than 30 years. According to a widely-used paradigm, the modelling of cognitive processes should mainly operate on the computational level and be targeted at the idealised competence, rather than the actual performance of cognisers in a specific domain. In this paper, we explore how this paradigm can be adopted and revised to understand mathematical problem solving. The computational-level approach applies methods from (...) computational complexity theory and focuses on optimal strategies for completing cognitive tasks. However, human cognitive capacities in mathematical problem solving are essentially characterised by processes that are computationally sub-optimal, because they initially add to the computational complexity of the solutions. Yet, these solutions can be optimal for human cognisers given the acquisition and enactment of mathematical practices. Here we present diagrams and the spatial manipulation of symbols as two examples of problem solving strategies that can be computationally sub-optimal but humanly optimal. These aspects need to be taken into account when analysing competence in mathematical problem solving. Empirically informed considerations on enculturation can help identify, explore, and model the cognitive processes involved in problem solving tasks. The enculturation account of mathematical problem solving strongly suggests that computational-level analyses need to be complemented by considerations on the algorithmic and implementational levels. The emerging research strategy can help develop algorithms that model what we call enculturated cognitive optimality in an empirically plausible and ecologically valid way. (shrink)

Causal closure arguments against interactionist dualism are currently popular amongst physicalists. Such an argument appeals to some principles of the causal closure of the physical, together with certain other premises, to conclude that at least some mental events are identical with physical events. However, it is crucial to the success of any such argument that the physical causal closure principle to which it appeals is neither too strong nor too weak by certain standards. In this paper, it is argued that (...) various forms of naturalistic dualism, of an emergentist character, are consistent with the strongest physical causal closure principles that can plausibly be advocated.

Prioritarianism is a variant of utilitarianism. It differs from utilitarianism in that benefiting individuals matters more the worse off these individuals are. On this view, there are two standard ways of handling risky prospects: Ex-Post Prioritarianism adjusts for prioritizing the worse off in final outcomes and then values prospects by the expectation of the sum total of those adjusted values, whereas Ex-Ante Prioritarianism adjusts for prioritizing the worse off on each individual's expectation and then values prospects by the sum total (...) of those adjusted expectations. A standard objection to Ex-Post Prioritarianism is that it violates Ex-Ante Pareto, that is, it prescribes choices that worsen the expectations for everyone. In this article, I argue that Ex-Ante Prioritarianism suffers from much the same problem: it violates a sequential version of Ex-Ante Pareto, that is, it prescribes sequences of choices that worsen the expectations for everyone.

Because corporate social responsibility can be beneficial to both companies and its stakeholders, interest in factors that support CSR performance has grown in recent years. A thorough integration of CSR in core business processes is particularly important for achieving effective long-term CSR practices. Here, we explored the individual CSR-related competencies that support CSR implementation in a corporate context. First, a systematic literature review was performed in which relevant scientific articles were identified and analyzed. Next, 28 CSR directors and managers were (...) interviewed. The literature review complemented with interview data resulted in the following eight distinct CSR-related competencies: Anticipating CSR challenges; Understanding CSR-relevant systems and subsystems; Understanding CSR-relevant standards; CSR management competencies, including Leading CSR programs, Managing CSR programs, and Identifying and realizing CSR-related business opportunities; Realizing CSR-supportive interpersonal processes; Employing CSR-supportive personal characteristics and attitudes; Personal value-driven competencies, including Ethical normative competencies, Balancing personal ethical values and business objectives, and Realizing self-regulated CSR-related behaviors and active involvement; and Reflecting on personal CSR views and experiences. Based on these results, implications for further research on this topic, as well as implications for practitioners, are discussed. (shrink)

This article aims to clarify how aspects of current chemical understanding relate to some important contemporary problems of philosophy. The first section points out that the long-running philosophical debates concerning how properties stay together in substances have neglected the important topic of structure-determining closure. The second part describes several chemically-important types of closure and the third part shows how such closures ground the properties of chemical substances. The fourth section introduces current discussions of structural realism (SR) and contextual emergence: the (...) final sections reconsider the coherence of the properties of substances and concludes that recognition that structures qualify as determinants of specific outcomes—as ‘causes’ as that designation is used in Standard English—clarifies how properties stay together in chemical entities, and by analogy, how characteristics cohere in ordinary items.

Recently, the concept of "gender identity" has enjoyed a great deal of attention in gender metaphysics. This seems to be motivated by the goal of creating trans-inclusive theory, by explaining trans people's genders. In this paper, we aim to unmotivate this project. Notions of "gender identity" serve important pragmatic purposes for trans people, such as satisfying the curiosity of non-trans people, and, relatedly, securing our access to important goods like legal rights and medical care. However, we argue that this does (...) not mean that "gender identity" is a metaphysically substantial thing that deserves extensive theoretical attention. There are reasons to be skeptical of such a concept. We trace the history of "gender identity," primarily to identify its roots in trans-antagonistic medical theory and its connections to the problematic "wrong-body" model--a legacy that has pathologized and flattened trans experience. Moreover, we argue that trans people primarily use "gender identity" to explain ourselves to non-trans people, rather than to discuss ourselves among ourselves. Thus, we urge theorists to resist the urge to substantiate gender identity. Instead, we encourage the development of new and better concepts, ones that attend to the lived realities of trans community and the flourishing gender terms and practices that are constructed there. If these lived realities are taken seriously, there is no need to “explain” trans people’s genders; we can simply see them as they are. (shrink)

The Evolutionary Manifesto shows that evolution is directional and demonstrates that this has major implications for humanity. The Manifesto shows that humanity must align its social systems and behaviour with the trajectory of evolution if we are to survive and thrive into the future. The Manifesto goes on to demonstrate that humanity has an essential role to play in the future evolution of life on this planet. It demonstrates that life on Earth has reached a critical stage in evolution’s trajectory. (...) Up to now evolution has moved along its trajectory blindly and unconsciously. But if evolution on Earth is to continue to advance successfully in the future, the process will have to be driven intentionally and consciously by humanity. In this way, a proper understanding of evolution shows us how we can live a life that matters in a larger scheme of things. An evolutionary worldview answers the fundamental existential question that faces us all: “What should I do with my life?” The Manifesto outlines in broad terms what humanity must do to advance the evolutionary process—how we will intentionally have to re-make our political, social and economic systems, and how we will need to develop our cognition and consciousness. As such, the Manifesto presents a detailed case for evolutionary activism--coordinated action directed at advancing the evolutionary process intentionally. (shrink)

In this paper the propositional logic LTop is introduced, as an extension of classical propositional logic by adding a paraconsistent negation. This logic has a very natural interpretation in terms of topological models. The logic LTop is nothing more than an alternative presentation of modal logic S4, but in the language of a paraconsistent logic. Moreover, LTop is a logic of formal inconsistency in which the consistency and inconsistency operators have a nice topological interpretation. This constitutes a new proof of (...) S4 as being "the logic of topological spaces", but now under the perspective of paraconsistency. (shrink)

In the world of philosophy of science, the dominant theory of confirmation is Bayesian. In the wider philosophical world, the idea of inference to the best explanation exerts a considerable influence. Here we place the two worlds in collision, using Bayesian confirmation theory to argue that explanatoriness is evidentially irrelevant.
