Health institutions recommend that young infants be exclusively breastfed on demand, and it is widely held that parents who can breastfeed have an obligation to do so. This has been challenged in recent philosophical work, especially by Fiona Woollard. Woollard’s work critically engages with two distinct views of parental obligation that might ground such an obligation—based on maximal benefit and avoidance of significant harm—to reject an obligation to breastfeed. While agreeing with Woollard’s substantive conclusion, this paper (drawing on philosophical discussion (...) of the ‘right to rear’) argues that there are several more moderate views of parental obligation which might also be thought to ground parental obligation. We first show that an obligation to breastfeed might result not from a general obligation to maximally benefit one’s child, but from what we call ‘choice-specific’ obligations to maximise benefit within particular activities. We then develop this idea through two views of parental obligation—the Dual Interest view, and the Best Custodian view—to ground an obligation to exclusively breastfeed on demand, before showing how both these more moderate views fail. Finally, we argue that not only is there no general obligation to breastfeed children, but that it is often morally right not to do so. Since much advice from health institutions on this issue implies that exclusive breastfeeding on demand is the best option for all families, our argument drives the feeding debate forward by showing that this advice often misrepresents parents’ moral obligations in potentially harmful ways.

This article seeks to describe in general terms what has become the standard way of conceptualizing moral injury in the clinical psychological and psychiatric literature, which is the key source for applications of the concept in other domains. What we call “the standard model” draws on certain assumptions about beliefs, mental states, and emotions as well as an implicit theory of causation about how various forms of harm arise from certain experiences or “events” that violate persons’ moral beliefs and systems. (...) Our analysis makes these assumptions more explicit and subjects them to critical scrutiny. In so doing, we survey the current literature and identify basic features of how moral injuries are defined, how they are thought to occur, and the forms of treatment or repair that appear to be indicated. We caution that it matters how moral experience is characterized and argue that an alternative understanding of what is the moral in moral injury is important for overcoming critical challenges to the standard model. Moreover, recently evolving approaches to moral repair could be more consistent with an alternative model. Our concluding suggestion is that a more robust account of the nature of moral experience and its relations to self-identity and social experience more generally could advance understanding of the etiology of moral injury and promote rehabilitation.

Emphasizing the human body in all of its forms, Beauty Unlimited expands the boundaries of what is meant by beauty both geographically and aesthetically. Peg Zeglin Brand and an international group of contributors interrogate the body and the meaning of physical beauty in this multidisciplinary volume. This striking and provocative book explores the history of bodily beautification; the physicality of socially or culturally determined choices of beautification; the interplay of gender, race, class, age, sexuality, and ethnicity within and on the (...) body; and the aesthetic meaning of the concept of beauty in an increasingly globalized world.

PRINCÍPIOS DA DIGESTÃO DOS ALIMENTOS NOS BEZERROS -/- -/- E. I. C. da Silva -/- Departamento de Agropecuária – IFPE Campus Belo Jardim -/- Departamento de Zootecnia – UFRPE sede -/- -/- PRINCÍPIOS DA DIGESTÃO DOS ALIMENTOS NOS BEZERROS -/- -/- INTRODUÇÃO -/- Se todos os bezerros pudessem ser criados por suas mães, haveria pouca necessidade de inúmeros livros, artigos e trabalhos, como esse, sobre a criação e o manejo básico desses animais. A maioria das vacas desempenha um ótimo papel (...) na criação dos seus descendentes, desde que sejam tomados os devidos cuidados com relação a alimentação, saúde e a outros aspectos relativos à criação desses neonatos. A essência da pecuária bovina relativa à criação de bezerros é manter esses animais vivos e aptos o suficiente para desempenhar atividades produtivas de grande importância na propriedade. Para tanto, os criadores necessitam entender o desenvolvimento do trato digestivo do bezerro e os conceitos básicos da digestão dos alimentos por ele, e é isso que pretendo aclarar de forma clara e concisa com esse trabalho. -/- -/- 1.1 O TRATO DIGESTIVO DO BEZERRO -/- Um animal adulto necessita de quatro estômagos funcionais para dar-lhe a capacidade de utilizar a ampla gama de alimentos disponíveis. -/- O retículo e o rúmen abrigam milhões de micróbios que fermentam e digerem o material vegetal, em especial às presentes nas forragens. O omaso permite a absorção de água do conteúdo do intestino. O abomaso, ou quarto estômago, é o verdadeiro estômago, comparável ao dos humanos, e permite a digestão ácida dos alimentos. -/- O bezerro muito jovem não desenvolve a capacidade de digerir o pasto, sendo assim o abomaso é o único estômago funcional ao nascer. Tanto os animais recém-nascidos como os adultos têm um intestino delgado funcional que permite a digestão alcalina dos alimentos. -/- A figura 1 ilustra a anatomia dos estômagos e intestino delgado de um bezerro recém-nascido. Esse diagrama esquemático mostra as dimensões relativas dos quatro estômagos, o sulco esofágico, que vai do esôfago até o abomaso, e o esfíncter pilórico ou válvula no fundo do abomaso, que controla a velocidade de movimento do conteúdo do intestino no duodeno. -/- O omaso e o abomaso representam cerca de 70% da capacidade total do estômago no bezerro recém-nascido. Por outro lado, nas vacas adultas, eles compõem apenas 30% da capacidade total do estômago (figura 2). -/- A digestão dos alimentos é auxiliada pela secreção de certos produtos químicos denominados enzimas, que estão presentes nas várias partes do intestino. Por exemplo, os bezerros produzem a enzima renina na parede do abomasal para auxiliar na digestão das proteínas do leite, enquanto a lactase é produzida na parede do duodeno para a digestão do açúcar do leite (lactose). Estas enzimas operam mais eficazmente em diferentes níveis de acidez no conteúdo do intestino, ácido no abomaso e alcalino no duodeno. Para conseguir isso, o bezerro segrega eletrólitos, ou sais minerais, com as enzimas, para mudar o conteúdo do intestino de um tipo para outro. -/- Os produtos finais da digestão dos diferentes componentes dos alimentos são absorvidos através da parede do intestino, mediante as vilosidades intestinais, para a corrente sanguínea, onde são levados para as diferentes partes do corpo para o crescimento e desenvolvimento do animal. -/- -/- 1.2 O BEZERRO ALIMENTADO COM LEITE -/- O Leite ou substituto do leite, quer seja apreendido através de uma teta ou bebido de um balde, é canalizado do esôfago através do sulco esofágico para o abomaso. Este sulco é um pequeno canal na parede do rúmen que é controlado por músculos que permitem que os líquidos sejam diretamente enviados para o abomaso e que não entrem no rúmen. O sulco é ativado em resposta a diferentes estímulos. Funciona bem quando os bezerros amamentam-se através das tetas das mães, mas às vezes não funciona quando bebem de um balde. Essa parece ser uma condição psicológica em resposta aos bezerros separados de suas mães. A maioria dos bezerros podem ser treinados pelo tratador para beber o leite do balde rapidamente e bem, a metodologia empregada é a da persuasão do animal, ao qual o mesmo possa responder positivamente à nova rotina diária e à mãe substituta na forma do criador do bezerro. Quando o leite ou o substituto do leite entra no abomaso, forma um coágulo firme dentro de alguns minutos sob a influência das enzimas renina e pepsina. Este é o mesmo processo envolvido na fabricação de queijo ou junket, usando renina para coagular a proteína do leite. A coagulação do leite retarda a taxa em que flui para fora do abomaso, permitindo assim uma liberação constante de nutrientes alimentares em todo o intestino e, eventualmente, para a corrente sanguínea. Pode levar de 12 a 18 horas para que a coalhada de leite seja totalmente digerida. -/- As enzimas que atuam nas proteínas do leite requerem um ambiente ácido e esse é fornecido pela secreção do ácido clorídrico no abomaso. No entanto, até que a digestão ácida esteja operando de forma eficiente, e isso pode levar até sete dias, a única forma de proteína que pode ser digerida é a caseína. Não há substituto para a caseína no bezerro muito jovem. Os substitutos do leite que contêm outras formas de proteína não podem ser devidamente digeridos até que os bezerros sejam mais velhos. Logo, é necessário muito cuidado para não fornecer substitutos ou sucedâneos que contenham fontes proteicas que não possam ser digeridas pelo estômago do animal, para que não ocasione complicações gastrintestinais. -/- A digestão do leite pode ser melhorada com a inclusão de coalho, que pode ser obtido a partir de fábricas de queijo ou aditivos comerciais de leite de bezerro para a primeira semana ou mais. Esses produtos comerciais podem fornecer ácidos adicionais para reduzir o pH abomasal e incrementar a quantidade de enzimas e bactérias específicas para aumentar a taxa de degradação da coalhada de leite. Tais aditivos são chamados probióticos, na medida em que ajudam nos processos digestivos normais. A pesquisa nem sempre os encontrou para melhorar o desempenho e a saúde dos bezerros, e eles são mais propensos a ser benéficos quando os bezerros estão sofrendo de problemas de saúde. Além disso, a sua eficácia, em termos de custo-benefício é, por vezes, questionada. -/- Qualquer leite de uma alimentação anterior está envolvido neste coágulo recém-formado. As proteínas líquidas de soro de leite e a lactose são rapidamente separadas da coalhada de leite e passam para o abomaso. A gordura do leite contida na coalhada de leite é decomposta por outra enzima, a lipase. Esta é secretado na boca pela saliva e incorporada quando o leite é engolido. A alimentação pelas tetas em vez da alimentação através do balde parece produzir mais saliva e, portanto, mais lipase. A digestão adicional da proteína do leite e da gordura ocorre no duodeno com a ajuda das enzimas produzidas no pâncreas. -/- A lactose, que é rapidamente liberada da coalhada de leite no abomaso, é dividida em glicose e galactose e estas são absorvidas na corrente sanguínea para formar a principal fonte de energia para os bezerros jovens. -/- As gorduras são divididas em ácidos graxos e glicerol para absorção e uso como energia, enquanto as proteínas são divididas em aminoácidos e peptídeos para absorção e uso como fontes de proteína corporal. -/- O amido de cereais, por exemplo, é uma importante fonte de energia em bezerros mais velhos, mas esses animais, nas suas primeiras semanas de vida, não conseguem digerir o amido. -/- O abomaso não é ácido até que o bezerro tenha 1-2 dias de idade e isso apresenta vantagens e desvantagens. A principal vantagem é que as proteínas imunes no colostro não podem ser digeridas nesse compartimento estomacal, por isso são absorvidas na corrente sanguínea na mesma forma quando produzidas pela vaca. Isso garante o seu papel como anticorpos para proteger contra as doenças e infecções. A baixa acidez do conteúdo abomasal no bezerro recém-nascido constitui um risco potencial das bactérias (e provavelmente vírus) tomadas através da boca. Estes não serão mortos pela digestão ácida, sendo assim podem passar para os intestinos, onde podem fazer mal ao bezerro recém-nascido. -/- Todos os bezerros pegam bactérias nos primeiros dias de vida e isso é essencial para o desenvolvimento normal do rúmen (flora microbiana). No entanto, a primeira bactéria a colonizar o intestino também pode causar danos. Desde que o bezerro tenha bebido colostro, os anticorpos maternos podem controlar a propagação dessas bactérias mais nocivas. -/- O bezerro alimentado com leite deve, então, produzir uma digestão ácida no abomaso e uma digestão alcalina no duodeno. Isto é conseguido pela produção de eletrólitos na parede do intestino. -/- Bezerros que sofrem de escoriações devido a distúrbios nutricionais ou infecções bacterianas podem perder grandes quantidades de água e eletrólitos em suas fezes. Estes devem ser reabastecidos como parte do tratamento para as escoriações. -/- O colostro é o primeiro leite produzido por vacas recém-paridas. Além de fornecer nutrientes essenciais para a alimentação animal, fornece anticorpos maternos que permitem a transferência passiva de imunidade contra doenças. As recomendações para a alimentação com colostro serão abordadas brevemente em outro trabalho. -/- -/- 1.3 DESENVOLVIMENTO DO RÚMEN E O PROCESSO DE DESMAME -/- Quando os bezerros são desmamados, o custo da criação diminui acentuadamente. Os custos de alimentação são mais baixos, os insumos de trabalho são reduzidos e a incidência de problemas de saúde é menor. No sentido econômico, faz sentido desmamar os bezerros assim que for razoável. No entanto, o bezerro é forçado a sofrer várias mudanças dramáticas, a saber: -/-  A fonte primária de nutrientes muda de líquido para sólido. -/-  A quantidade de matéria seca que o bezerro recebe é reduzida. -/-  O bezerro deve adaptar-se de um tipo monogástrico a um ruminante de digestão, que inclui a fermentação de alimentos. -/-  Mudanças na habitação e no manejo muitas vezes ocorrem em torno do desmame, o que pode aumentar o estresse. -/- Ao nascer, o rúmen é uma parte pequena e estéril do intestino que, ao desmame deve se tornar o compartimento mais importante dos quatro estômagos. Deve aumentar em tamanho, atividade metabólica interna e fluxo sanguíneo externo. Os cinco requisitos para o desenvolvimento ruminal são: -/-  Estabelecimento de bactérias. -/-  Líquido. -/-  Saída de material (ação muscular). -/-  Capacidade absortiva do tecido. -/-  Substrato para permitir o crescimento bacteriano, tais como minerais reciclados, bem como nutrientes para alimentação. -/- Antes do consumo de alimentos sólidos, as bactérias existentes fermentam o cabelo ingerido, o estrato e o leite que flui do abomaso para o rúmen. A maior parte da água que entra no rúmen provém da água livre (água real não contida no leite ou na solução substituta do leite). O leite contornará o rúmen através do sulco esofágico, enquanto a água livre não. -/- O rúmen se desenvolve a partir de um órgão muito pequeno em bezerros recém-nascidos (1-2 L) para a parte mais importante do intestino (25-30 L) por 3 meses de idade. Ele pode aumentar muito rapidamente durante as primeiras semanas de vida, dado o manejo da alimentação direita. -/- O crescimento do rúmen ocorre apenas sob a influência dos produtos finais da digestão no mesmo, que resultam da fermentação de alimentos sólidos pelos micróbios presentes nesse compartimento. O desenvolvimento ocorre em grande parte através do crescimento das papilas ruminais (figura 5 e 6) na parede ruminal (estruturas semelhantes a folhas na superfície interna), que aumentam a área superficial do rúmen e, portanto, a sua capacidade de absorver estes produtos finais de digestão. Portanto, os concentrados favorecem melhor o desenvolvimento dessas papilas ruminais. Para tanto, é necessário, com um tempo, ir incrementando a dieta sólida gradativamente para que esses animais deixem de consumir o leite das vacas produtoras e possam alimentar-se de ração e pastagens, que é a finalidade da criação de bovinos, ou seja, criar animais com menor custo possível e engordá-los através de ração, mas principalmente de pastagens. -/- A capacidade do rúmen e a ingestão de alimentos sólidos estão intimamente relacionadas. O desenvolvimento do rúmen é muito lento em bezerros alimentados com grandes quantidades de leite. O leite satisfaz seus apetites para que eles não tenham fome suficiente para comer qualquer alimento sólido. Logo, é necessário diminuir paulatinamente o fornecedor do leite para esses animais, favorecendo a ingestão de alimentos sólidos e desenvolvendo o rúmen, estômago que digere as fibras das forragens e que os tona animais peculiares. -/- A ruminação pode ocorrer com cerca de 2 semanas de idade e é uma boa indicação de que o rúmen está se desenvolvendo. Alimentos sólidos, bem como a ruminação, estimulam a produção de saliva e isso fornece nutrientes como ureia e bicarbonato de sódio para produzir os substratos para o crescimento e desenvolvimento da flora bacteriana. -/- No desmame precoce, é importante limitar a quantidade de leite oferecida e a sua disponibilidade durante todo o dia. Também é essencial fornecer alimentos sólidos. Os grosseiros (de baixa ou alta qualidade) devem ser oferecidos em combinação com concentrados de alta qualidade. -/- O criador deve tomar cuidado com o fornecimento de alimentos como a ração farelada, uma vez que essa ração pode entrar pelas vias nasais e ocasionar complicações respiratórias; há alguns relatos de bezerros mortos após a ingestão de ração farelada, na autópsia de um dos casos foi diagnosticada uma morte por esses grãos farelados presentes no pulmão. Portanto, para evitar complicações o ideal é que se forneça uma ração denominada peletizada. -/- Os alimentos grosseiros (volumosos) estimulam o desenvolvimento do rúmen, enquanto os concentrados fornecem nutrientes para a alimentação animal que não são fornecidos pelas quantidades limitadas de leite oferecidas. Sem os concentrados, o crescimento dos bezerros é lento, mas o rúmen ainda se desenvolve, resultando em animais barrigudos. -/- A ureia fornece nitrogênio para os micróbios, enquanto o bicarbonato de sódio atua como um tampão ruminal, ajudando a manter um pH estável no conteúdo do rúmen. Isso é, particularmente, importante quando os bezerros comem grandes quantidades de grãos de cereais na vida adulta, pois os micróbios do rúmen podem produzir muito ácido lático durante a fermentação desse material. -/- Envenenamento por grãos ou acidose ocorre quando os níveis de ácido lático são excessivamente elevados e tornam-se tóxicos para os micróbios do rúmen e, eventualmente, para o animal. Assim como os produtos finais que são absorvidos através da parede do rúmen, a fermentação microbiana produz os gases dióxido de carbono e metano e estes são normalmente exalados. Quando algo impede a fuga destes gases do rúmen, o inchaço pode se manifestar em qualquer fase da vida, diz-se do animal estufado. -/- -/- 1.4 O PAPEL DA FORRAGEM NO PROCESSO DE DESMAME -/- Existem inúmeras controvérsias acerca do papel da forragem no processo de desmame. Pesquisas realizadas na década de 1980 indicaram claramente que a forragem era benéfica, enquanto pesquisas da década de 1990 descobriram que nem sempre era necessário o fornecimento da forragem para que os bezerros fossem desmamados e que não sofresse estresse e nem apresentasse baixa eficiência produtiva e reprodutiva no futuro. Na maioria das pesquisas anteriores, os bezerros eram desmamados com a oferta de concentrados moídos como pellets com ou sem a presença de feno longo ou palha. Porém, a inclusão de forragens na dieta melhorou a ingestão e o desempenho, além de permitir o desmame precoce. -/- Na pesquisa posterior, os bezerros geralmente alimentavam-se de concentrados grosseiramente moídos, além de alguns volumosos, enquanto alguns até incluíam volumosos picados finos na mistura (às vezes chamados de mistura muesli por apresentar o capim e a ração). Nesses estudos, verificou-se que a inclusão de feno ou palha adicional teve pouco efeito no desempenho pré-desmame. -/- Os sistemas de criação de bezerros australianos frequentemente diferem dos demais, especialmente em áreas de parto sazonais. Um número excessivo elevado de bezerros precisam ser criados de uma só vez para lhes fornecer, a todos, currais individuais durante todo o seu período de amamentação. Consequentemente, os bezerros são criados em grupos. Além disso, os ingredientes da maioria dos concentrados para esses animais são finamente moídos. Nessas situações, descobriu-se que a palha limpa é um alimento útil e que deve ser incluso no período pré-desmame. Alguns agricultores preferem feno de boa qualidade, porém estes agricultores geralmente têm bezerros em grupos muito pequenos, muitas vezes um ou dois, por isso possuem maior controle sobre a ingestão de forragem. -/- Figura 7: A alimentação volumosa de bezerros alimentados com leite é uma questão controversa. Imagem cedida pelo IPA -/- É difícil e, portanto, mais caro que os produtores de rações incorporem feno picado nas refeições dos bezerros. Os pellets são muito mais fáceis, pois eles vão fluir para silos. Por fim, os produtores de leite devem incluir o componente volumoso no regime alimentar pré-desmame. A pastagem não é a fonte ideal de forragem volumosa para os bezerros alimentados com leite, uma vez que possui muito pouca fibra e uma baixa densidade de energia alimentar. O seu elevado teor de água limita a sua capacidade de fornecer energia alimentar adequada aos animais em crescimento. Para ingerir a pastagem a capacidade ruminal deveria ser maior, bezerros jovens simplesmente não conseguem comer pasto suficiente, a menos que seja de alta em qualidade. -/- Os bezerros criados com leite e fornecimento gradual de concentrados apresentam uma boa função ruminal às 3 semanas de vida, além de possuírem uma suficiente capacidade ruminal para o desmame entre às 4-6 semanas de idade. No entanto, se a dieta for baseada em leite restrito e pastagem de alta qualidade, a capacidade do rúmen pode não ser suficiente para o desmame até às 8-10 semanas de vida. Mesmo assim, as taxas de crescimento seriam menores em bezerros desmamados com base alimentar somente à pasto, uma vez que a ingestão de energia é insuficiente devido às limitações físicas da capacidade ruminal. -/- Se a qualidade for muito boa e produza apetite, os bezerros preferem volumosos ao invés do concentrado, o que leva a uma ingestão reduzida de nutrientes durante alimentação, tendo como efeito um crescimento mais lento. Quando volumosos e concentrados fornecem apetite no animal, juntamente com o leite limitado, os bezerros podem comer cerca de 10% de palha e 90% de concentrados. Sem o volumoso e a ruminação resultante, o desenvolvimento do rúmen será mais lento devido à falta de saliva e produtos finais da digestão de fibras presentes na parede celular das forragens. -/- -/- REFERÊNCIAS BIBLIOGRÁFICAS -/- -/- BEN ASHER, Aharon.

This paper identifies, develops, and argues for an interpretation of Mary Astell’s understanding of self-government. On this interpretation, what is essential to self-government, according to Astell, is an agent’s responsiveness to her own reasoning. The paper identifies two aspects of her theory of self-government: an ‘authenticity’ criterion of what makes our motives our own and an account of the capacities required for responsiveness to our own reasoning. The authenticity criterion states that when our motives arise from some external source (...) without validation by our own understanding of the reasons supporting them, then they are not our own. The capacities requisite for responsiveness to our own reasoning are those of examining and evaluating our own motives and of resisting the social pressure to conform to others’ opinions. An upshot of this interpretation of Astell’s theory of self-government is that it reveals her insights into the ways ‘custom’ can undermine an individual’s ability to govern oneself. (shrink)

When A utters a declarative sentence in a context to B, typically A can mean a proposition by the sentence, the sentence in context literally expresses a proposition, there are propositions A and B can agree the sentence literally expressed, and B can acquire knowledge from this testimonial exchange. In recent work on linguistic communication, each of these four platitudes has been challenged, and on the same basis: viz. on the ground that exactly which proposition the sentence expressed in context (...) is not discernible given the information provided by the context. I argue that, even if this is true, there will be propositional parts of the proposition expressed by the sentence in context which can be identified and that, consequently, the partial understanding afforded by the existence of such identifiable parts undermines the soundness of the arguments against the platitudes.

The vast literature on negative treatment of outgroups and favoritism toward ingroups provides many local insights but is largely fragmented, lacking an overarching framework that might provide a unified overview and guide conceptual integration. As a result, it remains unclear where different local perspectives conflict, how they may reinforce one another, and where they leave gaps in our knowledge of the phenomena. Our aim is to start constructing a framework to help remedy this situation. We first identify a few key (...) ideas for creating a theoretical roadmap for this complex territory, namely the principles of etiological functionalism and the dual inheritance theory of human evolution. We show how a “molecular” approach to emotions fits into this picture, and use it to illuminate emotions that shape intergroup relations. Finally, we weave the pieces together into the beginnings of a systematic taxonomy of the emotions involved in social interactions, both hostile and friendly. While it is but a start, we have developed the argument in a way that illustrates how the foundational principles of our proposed framework can be extended to accommodate further cases. (shrink)

The orthodox monadic determination thesis holds that we represent colour relations by virtue of representing colours. Against this orthodoxy, I argue that it is possible to represent colour relations without representing any colours. I present a model of iconic perceptual content that allows for such primitive relational colour representation, and provide four empirical arguments in its support. I close by surveying alternative views of the relationship between monadic and relational colour representation.

It is often thought that traditional recidivism prediction tools used in criminal sentencing, though biased in many ways, can straightforwardly avoid one particularly pernicious type of bias: direct racial discrimination. They can avoid this by excluding race from the list of variables employed to predict recidivism. A similar approach could be taken to the design of newer, machine learning-based (ML) tools for predicting recidivism: information about race could be withheld from the ML tool during its training phase, ensuring that the (...) resulting predictive model does not use race as an explicit predictor. However, if race is correlated with measured recidivism in the training data, the ML tool may ‘learn’ a perfect proxy for race. If such a proxy is found, the exclusion of race would do nothing to weaken the correlation between risk (mis)classifications and race. Is this a problem? We argue that, on some explanations of the wrongness of discrimination, it is. On these explanations, the use of an ML tool that perfectly proxies race would (likely) be more wrong than the use of a traditional tool that imperfectly proxies race. Indeed, on some views, use of a perfect proxy for race is plausibly as wrong as explicit racial profiling. We end by drawing out four implications of our arguments. (shrink)

This article argues for a task-based approach to identifying and individuating cognitive systems. The agent-based extended cognition approach faces a problem of cognitive bloat and has difficulty accommodating both sub-individual cognitive systems ("scaling down") and some supra-individual cognitive systems ("scaling up"). The standard distributed cognition approach can accommodate a wider variety of supra-individual systems but likewise has difficulties with sub-individual systems and faces the problem of cognitive bloat. We develop a task-based variant of distributed cognition designed to scale up and (...) down smoothly while providing a principled means of avoiding cognitive bloat. The advantages of the task-based approach are illustrated by means of two parallel case studies: re-representation in the human visual system and in a biomedical engineering laboratory. (shrink)

This chapter has two aims. First, I distinguish between two forms of testimonial injustice: identity-based testimonial injustice and content-based testimonial injustice. Second, I utilize this distinction to develop a partial explanation for the persistent lack of diverse practitioners in academic philosophy. Specifically, I argue that both identity-based and content-based testimonial injustice are prevalent in philosophical discourse and that this prevalence introduces barriers to participation for those targeted. As I show, the dual and compounding effects of identity-based and content-based testimonial injustice (...) in philosophy plausibly contribute to a lack of diversity in the social identities of practitioners and the discourses in which practitioners are engaged.

The central aim of this article is to specify the ontological nature of constitutive mechanistic phenomena. After identifying three criteria of adequacy that any plausible approach to constitutive mechanistic phenomena must satisfy, we present four different suggestions, found in the mechanistic literature, of what mechanistic phenomena might be. We argue that none of these suggestions meets the criteria of adequacy.

It's sometimes thought that context-invariant linguistic meaning must be a character (a function from context types to contents) i.e. that linguistic meaning must determine how the content of an expression is fixed in context. This is thought because if context-invariant linguistic meaning were not a character then communication would not be possible. In this paper, I explain how communication could proceed even if context-invariant linguistic meaning were not a character.

Infallibilism is commonly rejected because it is apparently subject to easy counter-examples. I describe a strategy that infallibilists can use to resist this objection. Because the sentences used in the counter-examples to express evidence and belief are context-sensitive, the infallibilist can insist that such counter-examples trade on a vacillation between different readings of these sentences. I describe what difficulties await those who try to produce counter-examples against which the proposed strategy is ineffective.

The idea of using responsibility in the allocation of healthcare resources has been criticized for, among other things, too readily abandoning people who are responsible for being very badly off. One response to this problem is that while responsibility can play a role in resource allocation, it cannot do so if it will leave those who are responsible below a “sufficiency” threshold. This paper considers first whether a view can be both distinctively sufficientarian and allow responsibility to play a role (...) even for those who will be left with very poor health. It then draws several further distinctions that may affect the application of responsibility at this level. We conclude that a more plausible version of the sufficientarian view is to allow a role for responsibility where failure to do so will leave someone else who is not responsible below the sufficiency threshold. However, we suggest that individuals must exhibit “sufficient responsibility” in order for this to apply, involving both a sufficient level of control and an avoidable failure to respond adequately to reasons for action.

There is significant controversy over whether patients have a ‘right not to know’ information relevant to their health. Some arguments for limiting such a right appeal to potential burdens on others that a patient’s avoidable ignorance might generate. This paper develops this argument by extending it to cases where refusal of relevant information may generate greater demands on a publicly funded healthcare system. In such cases, patients may have an ‘obligation to know’. However, we cannot infer from the fact that (...) a patient has an obligation to know that she does not also have a right not to know. The right not to know is held against medical professionals at a formal institutional level. We have reason to protect patients’ control over the information that they receive, even if in individual instances patients exercise this control in ways that violate obligations. (shrink)

This paper resolves a paradox concerning colour constancy. On the one hand, our intuitive, pre-theoretical concept holds that colour constancy involves invariance in the perceived colours of surfaces under changes in illumination. On the other, there is a robust scientific consensus that colour constancy can persist in cerebral achromatopsia, a profound impairment in the ability to perceive colours. The first stage of the solution advocates pluralism about our colour constancy capacities. The second details the close relationship between colour constancy and (...) contrast. The third argues that achromatopsics retain a basic type of colour constancy associated with invariants in contrast processing. The fourth suggests that one person-level, conscious upshot of such processing is the visual awareness of chromatic contrasts ‘at’ the edges of surfaces, implicating the ‘colour for form’ perceptual function. This primitive type of constancy sheds new light on our most basic perceptual capacities, which mark the lower borders of representational mind. (shrink)

According to telling based views of testimony (TBVs), B has reason to believe that p when A tells B that p because A thereby takes public responsibility for B's subsequent belief that p. Andrew Peet presents a new argument against TBVs. He argues that insofar as A uses context-sensitive expressions to express p, A doesn't take public responsibility for B's belief that p. Since context-sensitivity is widespread, the kind of reason TBVs say we have to believe what we're told, is (...) not widespread. Peet doesn't identify any problem with his own argument though he does attempt to limit its sceptical potential by identifying special contexts in which TBVs stand a chance of success. A more general defence of TBVs can be provided by showing Peet's argument to be unsound. I argue that Peet's argument is unsound because it requires us to wrongly suppose that speakers do far less labour than their audiences in context-sensitive linguistic communication. I aim to show why—in the context of the epistemology of testimony and the philosophy of language—it's important to recognize the labour that speakers can do, and so can can be held responsible for not doing, in episodes of context-sensitive linguistic communication.

Mark Richard argues for truth-relativism about claims made using gradable adjectives. He argues that truth-relativism is the best explanation of two kinds of linguistic data, which I call: true cross-contextual reports and infelicitous denials of conflict. Richard claims that such data are generated by an example that he discusses at length. However, the consensus is that these linguistic data are illusory because they vanish when elaborations are added to examples of the same kind as Richard’s original. In this paper I (...) defend the reality of Richard’s data. I show that, in trying to make their point, Richard’s critics have focused upon examples that are similar in some respects to Richard’s original but which lack a crucial feature of that original. When we ensure that this feature is in place, elaborations which make the data vanish are not possible. Richard’s critics therefore fail to show that the data generated by Richard’s original example are illusory. (shrink)

There is an ongoing increase in the use of mobile health technologies that patients can use to monitor health-related outcomes and behaviours. While the dominant narrative around mHealth focuses on patient empowerment, there is potential for mHealth to fit into a growing push for patients to take personal responsibility for their health. I call the first of these uses ‘medical monitoring’, and the second ‘personal health surveillance’. After outlining two problems which the use of mHealth might seem to enable us (...) to overcome—fairness of burdens and reliance on self-reporting—I note that these problems would only really be solved by unacceptably comprehensive forms of personal health surveillance which applies to all of us at all times. A more plausible model is to use personal health surveillance as a last resort for patients who would otherwise independently qualify for responsibility-based penalties. However, I note that there are still a number of ethical and practical problems that such a policy would need to overcome. The prospects of mHealth enabling a fair, genuinely cost-saving policy of patient responsibility are slim. (shrink)

This article is a rebuttal to Robert G. Cavin and Carlos A. Colombetti’s article, “Assessing the Resurrection Hypothesis: Problems with Craig’s Inference to the Best Explanation,” which argues that the Standard Model of current particle physics entails that non-physical things (like a supernatural God or a supernaturally resurrected body) can have no causal contact with the physical universe. As such, they argue that William Lane Craig’s resurrection hypothesis is not only incompatible with the notion of Jesus physically appearing to the (...) disciples, but the resurrection hypothesis is significantly limited in both its explanatory scope and explanatory power. This article seeks to demonstrate why their use of the Standard Model does not logically entail a rejection of the physical resurrection of Jesus when considering the scope and limitations of science itself.

This article presents a semantic analysis of indirect speech reports. The analysis aims to explain a combination of two phenomena. First, there are true utterances of sentences of the form α said that φ which are used to report an utterance u of a sentence wherein φ's content is not u's content. This implies that in uttering a single sentence, one can say several things. Second, when the complements of these reports (and indeed, these reports themselves) are placed in conjunctions, (...) the conjunctions are typically infelicitous. I argue that this combination of phenomena can be explained if speech reports report (perhaps contingent) parts of the contents of the sentences reported. (shrink)

This paper argues that general skills and the varieties of subject-specific discourse are both important for teaching, learning and practising critical thinking. The former is important because it outlines the principles of good reasoning simpliciter (what constitutes sound reasoning patterns, invalid inferences, and so on). The latter is important because it outlines how the general principles are used and deployed in the service of ‘academic tribes’. Because critical thinking skills are—in part, at least—general skills, they can be applied to all (...) disciplines and subject-matter indiscriminately. General skills can help us assess reasoning independently of the vagaries of the linguistic discourse we express arguments in. The paper looks at the debate between the ‘specifists’—those who stress the importance of critical thinking understood as a subject-specific discourse—and the ‘generalists’—those that stress the importance of critical thinking understood independently of disciplinary context. The paper suggests that the ‘debate’ between the specifists and the generalists amounts to a fallacy of the false alternative, and presents a combinatory-‘infusion’ approach to critical thinking.

While there is considerable disagreement on the precise nature of material objecthood, it is standardly assumed that material objects must be spatial. In this paper, I provide two arguments against this assumption. The first argument is made from largely a priori considerations about modal plenitude. The possibility of non-spatial material objects follows from commitment to certain plausible principles governing material objecthood and plausible principles regarding modal plenitude. The second argument draws from current philosophical discussions regarding theories of quantum gravity and (...) the emergence of spacetime. When it is appreciated what possible worlds these current theories commit us to, the possibility of non-spatial material objects will follow. Thus, either route will lead us to the possibility of non-spatial material objects. The significance of this result is that we need to revise our accounts of material objecthood to both accommodate these possibilities and the theories that lead to them. (shrink)

Most of us believe that partiality applies in a broad range of relationships. One relationship on which there is much disagreement is co-nationality. Some writers argue that co-national partiality is not justified in certain cases, like killing in war, since killing in defense of co-nationals is intuitively impermissible in other contexts. I argue that this approach overlooks an important structural feature of partiality—namely, that its scope is sometimes restricted. In this essay, I show how some relationships that generate reasons of (...) partiality are restricted in scope—that is, they generate reasons within particular contexts or with respect to particular goods. I then argue that co-national partiality is scope restricted. I then show how this fact helps proponents of co-national partiality overcome the aforementioned objection to its application in cases like war. (shrink)

In this paper, I defend the agent/patient distinction against critics who argue that causal interactions are symmetrical. Specifically, I argue that there is a widespread type of causal interaction between distinct entities, resulting in a type of ontological asymmetry that provides principled grounds for distinguishing agents from patients. The type of interaction where the asymmetry is found is when one of the entities undergoes a change in kind, structure, powers, or intrinsic properties as a result of the interaction while the (...) other does not. Interactions of this type are widespread in molecular biology and chemistry. I focus specifically on (i) the actions of enzymes on substrates and (ii) water molecules breaking the bonds of polarized molecules. Finally, I respond to objections by laying out and to a limited extent defending three commitments of my account: emergent entities and powers, realism about chemical kinds or structures, and the assumption of the agent/patient distinction in functional attributions in biology.

Several philosophers have recently claimed that if a proposition is cancellable from an uttered sentence then that proposition is not entailed by that uttered sentence. The claim should be a familiar one. It has become a standard device in the philosopher's tool-kit. I argue that this claim is false. There is a kind of entailment—which I call “modal entailment”—that is context-sensitive and, because of this, cancellable. So cancellability does not show that a proposition is not entailed by an uttered sentence. (...) I close the paper by describing an implication this has for a disagreement between J. L. Austin and Grice concerning the relation between felicity and truth. (shrink)

This paper argues that Moore's specifist defence of critical thinking as ‘diverse modes of thought in the disciplines’, which appeared in Higher Education Research & Development, 30(3), 2011, is flawed as it entrenches relativist attitudes toward the important skill of critical thinking. The paper outlines the critical thinking debate, distinguishes between ‘top-down’, ‘bottom-up’ and ‘relativist’ approaches and locates Moore's account therein. It uses examples from one discipline-specific area, namely, the discipline of Literature, to show that the generalist approach to critical (...) thinking does not ‘leave something out’ and outlines why teaching ‘generic’ critical thinking skills is central to tertiary education, teaching and learning, and employment opportunities for students. The paper also defends the assessment of critical thinking skills. (shrink)

There is a correlation between positions taken on some scientific questions and political leaning. One way to explain this correlation is the cultural cognition hypothesis (CCH): people's political leanings are causing them to process evidence to maintain fixed answers to the questions, rather than to seek the truth. Another way is the different background belief hypothesis (DBBH): people of different political leanings have different background beliefs which rationalize different positions on these scientific questions. In this article, I argue for two (...) things. I argue that two attempts by proponents of the CCH to discredit the DBBH fail. And I argue that this matters, because while the CCH makes epistemic paternalistic interventions seem called for (as some philosophers have argued compellingly), the DBBH does not. The DBBH makes it much easier to stay closer to an ideal of deliberative democracy. (shrink)

Some people are multi-billionaires; others die because they are too poor to afford food or medications. In many countries, people are denied rights to free speech, to participate in political life, or to pursue a career, because of their gender, religion, race or other factors, while their fellow citizens enjoy these rights. In many societies, what best predicts your future income, or whether you will attend college, is your parents’ income. -/- To many, these facts seem unjust. Others disagree: even (...) if these facts are regrettable, they aren’t issues of justice. A successful theory of justice must explain why clear injustices are unjust and help us resolve current disputes. -/- John Rawls (1921-2002) was a Harvard philosopher best known for his A Theory of Justice (1971), which attempted to define a just society. Nearly every contemporary scholarly discussion of justice references A Theory of Justice. This essay reviews its main themes. (shrink)

Healthcare practitioners have access to a range of ethical guidance. However, the normative role of this guidance in ethical decision-making is underexplored. This paper considers two ways that healthcare practitioners could approach ethics guidance. We first outline the idea of deference to ethics guidance, showing how an attitude of deference raises three key problems: moral value; moral understanding; and moral error. Drawing on philosophical literature, we then advocate an alternative framing of ethics guidance as a form of moral testimony by (...) colleagues and suggest that a more promising attitude to ethics guidance is to approach it in the spirit of ‘critical engagement’ rather than deference.

Argument mapping is a way of diagramming the logical structure of an argument to explicitly and concisely represent reasoning. The use of argument mapping in critical thinking instruction has increased dramatically in recent decades. This paper overviews the innovation and provides a procedural approach for new teaches wanting to use argument mapping in the classroom. A brief history of argument mapping is provided at the end of this paper.

“Critical thinking in higher education” is a phrase that means many things to many people. It is a broad church. Does it mean a propensity for finding fault? Does it refer to an analytical method? Does it mean an ethical attitude or a disposition? Does it mean all of the above? Educating to develop critical intellectuals and the Marxist concept of critical consciousness are very different from the logician’s toolkit of finding fallacies in passages of text, or the practice of (...) identifying and distinguishing valid from invalid syllogisms. Critical thinking in higher education can also encompass debates about critical pedagogy, i.e., political critiques of the role and function of education in society, critical feminist approaches to curriculum, issues related to what has become known as critical citizenship, or any other education-related topic that uses the appellation “critical”. Equally, it can, and usually does, refer to the importance and centrality of developing general skills in reasoning—skills that we hope all graduates possess. Yet, despite more than four decades of dedicated scholarly work “critical thinking” remains as elusive as ever. As a concept, it is, as Raymond Williams has noted, a ‘most difficult one’ (Williams, 1976, p. 74). (shrink)

Patients are generally assumed to have the right to choices about treatment, including the right to refuse treatment, which is constrained by considerations of cost‐effectiveness. Independently, many people support the idea that patients who are responsible for their ill health should incur penalties that non‐responsible patients do not face. Surprisingly, these two areas have not received much joint attention. This paper considers whether restricting the scope of responsibility to pre‐treatment decisions can be justified, or whether a demand to hold people (...) responsible for 'usual suspect' choices such as smoking or failure to exercise commits us to also holding people responsible for their treatment choices. I argue that there is no good reason to support this restriction: those who advocate responsibility for (some) pre‐treatment choices should also advocate responsibility for (some) treatment choices. However, I also note that, as with pre‐treatment choices, patients may sometimes have reason to choose in ways that do not optimize their health. As such, I also consider a process, based on the idea of public reasons, for deciding which treatment choices patients cannot legitimately be held responsible for, along with a method for considering proposed changes to this category.

Context-sensitive expressions appear ill suited to the purpose of sharing content across contexts. Yet we regularly use them to that end (in regulations, textbooks, memos, guidelines, laws, minutes, etc.). This paper describes the utility of the concept of a metacontext for understanding cross-contextual content-sharing with context-sensitive expressions. A metacontext is the context of a group of contexts: an infrastructure that can channel non-linguistic incentives on content ascription so as to homogenize the content ascribed to context-sensitive expressions in each context in (...) the group. Documents composed of context-sensitive expressions can share content across contexts when supported by an appropriate metacontext. The bible has its church, the textbook its education system, the form its bureaucracy, and the manifesto its social movement. Some metacontexts support cross-contextual content-sharing. Some don’t. A promising research programme (one with practical importance) would take metacontexts as its unit of analysis. (shrink)

The use of Quality-Adjusted Life Years (QALYs) in healthcare allocation has been criticized as discriminatory against people with disabilities. This article considers a response to this criticism from Nick Beckstead and Toby Ord. They say that even if QALYs are discriminatory, attempting to avoid discrimination – when coupled with other central principles that an allocation system should favour – sometimes leads to irrationality in the form of cyclic preferences. I suggest that while Beckstead and Ord have identified a problem, it (...) is a misdiagnosis to lay it at the feet of an anti-discrimination principle. The problem in fact comes from a basic tension between respecting reasonable patient preferences and other ways of ranking treatment options. As such, adopting a QALY system does not solve the problem they identify. (shrink)

I reconcile the spatiotemporal location of repeatable artworks and impure sets with the non-location of natural numbers despite all three being varieties of abstract objects. This is possible because, while the identity conditions for all three can be given by abstraction principles, in the former two cases spatiotemporal location is a congruence for the equivalence relation featuring in the relevant principle, whereas in the latter it is not. I then generalize this to other ‘physical’ properties like shape, mass, and causal (...) powers. (shrink)

Funds and positions in philosophy should be awarded through systems that are reliable, objective, and efficient. One question usually taken to be relevant is how many publications people have in a group of well-respected journals. In the context of significant competition for jobs and funding, however, relying on quantity of publications creates a serious downside: the oft-lamented demand that we publish or perish. This article offers a systematic review of the problems involved in contemporary academic philosophy, and argues that the (...) resulting situation is bad not just for individual philosophers but also for philosophy itself: we are not working as a discipline to as high a standard as we might. The article then suggests some potential solutions, including some more detailed considerations around what seems a particularly promising option: a professional code of conduct for philosophers.

In this paper, we attempt to show that if Plantinga’s free will defence succeeds, his O Felix Culpa theodicy fails. For if every creaturely essence suffers from transworld depravity, then given that Jesus has a creaturely essence (as we attempt to show), it follows that Incarnation and Atonement worlds cannot be actualized by God, in which case we have anything but a felix culpa.

Computer-Assisted Argument Mapping (CAAM) is a new way of understanding arguments. While still embryonic in its development and application, CAAM is being used increasingly as a training and development tool in the professions and government. Inroads are also being made in its application within education. CAAM claims to be helpful in an educational context, as a tool for students in responding to assessment tasks. However, to date there is little evidence from students that this is the case. This paper outlines (...) the use of CAAM as an educational tool within an Economics and Commerce Faculty in a major Australian research university. Evaluation results are provided from students from a CAAM pilot within an upper-level Economics subject. Results indicate promising support for the use of CAAM and its potential for transferability within the disciplines. If shown to be valuable with further studies, CAAM could be included in capstone subjects, allowing computer technology to be utilised in the service of generic skill development. (shrink)

In the 1980s and 1990s, a series of attempts were made to put into U.S. law a civil rights ordinance that would make it possible to sue the makers and distributors of pornography for doing so (under certain conditions). One defence of such legislation has come to be called "the free speech argument against pornography." Philosophers Rae Langton, Jennifer Hornsby and Caroline West have supposed that this defence of the legislation can function as a liberal defence of the legislation: in (...) particular, a defence of the legislation based on the value of women's liberty. This would be somewhat unexpected given MacKinnon's own antipathy toward liberalism. In this paper, I argue that the free speech argument against pornography cannot be used as a liberal defence of the ordinances. The legislation is, to some extent, self-defeating insofar as it understood in terms acceptable to a fairly standard kind of liberal. This becomes apparent when we consider the value pornography can have for women, which we can see if we consider what female makers, distributors and consumers of pornography have to say about why they make, distribute and consume it.
