Resumen Ésta es la primera traducción al español de las guías “Atención después de la investigación: un marco para los comités de ética de investigación del National Health Service (NHS) (borrador versión 8.0)”. El documento afirma que existe una fuerte obligación moral de garantizar que los participantes enfermos de un estudio clínico hagan una transición después del estudio hacia una atención de la salud apropiada. Con “atención de la salud apropiada” se hace referencia al acceso para los participantes a la (...) atención de la salud, proporcionada principalmente por el National Health Service (en adelante NHS), el sistema de salud del Reino Unido, y/o a la intervención en estudio, también llamada producto o tratamiento en investigación. Las guías “Atención después de la investigación” están dirigidas principalmente a los miembros de los 79 comités de ética de investigación del NHS y a quienes presentan sus estudios de investigación ante estos comités. Se trata de un documento borrador muy avanzado, trabajado en numerosas reuniones, durante más de 3 años, que ha sido discutido por participantes de estudios y miembros de la comunidad, miembros y presidentes de comités de ética de investigación del Reino Unido, especialistas internacionales en ética de la investigación, representantes de la industria y otras partes interesadas. La redacción de las guías es producto de la colaboración de Neema Sofaer y Penney Lewis, ambas investigadoras del King’s College London, en el Centre of Medical Law and Ethics del Dickson Poon School of Law, y Hugh Davies, Asesor en Ética de la Investigación de la Health Research Authority (HRA) del NHS. El traductor del presente documento, Ignacio Mastroleo, participó del workshop en la Fundación Brocher (Ginebra, Suiza, diciembre de 2011) donde se revisó el borrador versión 7.0 y contribuyó en la revisión del borrador de la versión 8.0 durante el 2012. -/- Abstract This is the first Spanish translation of the guidelines “Care after research: a framework for NHS RECs (8th draft)”. The document states that there is a strong moral obligation to ensure that participants in a clinical study who are ill transition after the study to appropriate healthcare. The terms "appropriate healthcare" refer to participants’ access to health care, mainly provided by the National Health Service (NHS), the health system in the UK, and/or to the intervention study also named investigational treatment or product. The guides "Care after research" are mainly directed to members of the 79 NHS committees of research ethics (RECs) and to those who submit their research to these committees. This is a very advanced draft document, worked in several meetings, for more than three years, that has been discussed with study participants and community members, members and chairs of RECs in the UK, international specialists in research ethics, industry representatives and other stakeholders. The drafting of the guidelines is the result of the collaboration of Neema Sofaer and Penney Lewis, both researchers at King's College London, at the Centre of Medical Law and Ethics of Dickson Poon School of Law, and Hugh Davies, Research Ethics Advisor of the Health Research Authority (HRA) of the NHS. The translator of this document, Ignacio Mastroleo, attended the workshop at the Brocher Foundation (Geneva, Switzerland, December 2011) where draft version 7.0 was revised and contributed in the revision of draft version 8.0 during 2012.

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.

The 1970s Wages Against Housework (WAH) movement has much to offer as we form a “new normal” for life and work within the Covid-19 pandemic. WAH feminist philosophers Mariarosa Dalla Costa, Selma James, and Silvia Federici, as well as WAH critic Angela Davis outline the ways in which the housewife functions as a laborer within capitalist accumulation, as her duties to care for the home and rear the children generate the possibility of the husband to labor outside the home. This (...) role of the housewife in Dalla Costa and James’ “social factory” parallels the work of teachers and the chorus of demands to “return to the classroom” that were placed on teachers in the early stages of the Covid-19 pandemic. Highlighting these parallels, the argument of this essay is simple: Covid-19 has visibilized the underpaid and unpaid labor of teachers. We ought to engage this moment of visibilization to demand transformative change to the teaching profession. Due to the parallels between WAH's “housewife” and teachers, we have much to learn from WAH theorizing as we demand those transformative changes, especially now as we solidify our “new normal” more than two years since the Covid-19 pandemic began.

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.

In this work we present the function and we determine the nature of conventions and hypotheses for the scientific foundations according with the conventionalist doctrine that arose in France during the turning of the XIX century to the XX. The doctrine was composed by Henri Poincaré, Pierre Duhem and Édouard Le Roy. Moreover, we analyze the relation that conventions and hypotheses can establish with metaphysical thesis through criteria used by scientists in order to determine the preference for certain theories. Thereunto, (...) we promote an immanent interpretation of published works between 1891 and 1905. As result, we reveal that the authors, though being classified as belonging to the same doctrine, don't have only common grounds, but also divergences. Poincaré and Le Roy agree that geometrical conventions are chosen in accordance with convenience criteria. However, they disagree about the value convenience aggregate to scientific knowledge. In regards to natural phenomena, the three authors agree that reality can't be described univocally by the same set of conventions and hypotheses. Yet, Poincaré and Duhem both believe that there are experimental, rational and axiological criteria that justify scientist's satisfaction with certain theories and we indicate how those criteria are related with metaphysics. We conclude that conventionalists, even if warily and implicitly, searched to approach metaphysics in order to justify scientific activity. (shrink)

How does economics understand the human being? In this article, I present the current dominant conception of the human being in neoclassical theory, which is usually labelled as 'homo oeconomicus' (economic man). I describe the traits of this anthropology, and present the historical context in which it emerged. Then I make its critical evaluation. This is followed by a discussion of two recent alternative conceptions of the human being, which try to go beyond the individualist 'homo economicus' paradigm. I highlight (...) the recent contributions of John B. Davis and Luigino Bruni. Finally I reflect on some elements of Christian anthropology which can contribute to enrich the conception of the person in economics. (shrink)

Davies argues that the ontology of artworks as performances offers a principled way of explaining work-relativity of modality. Object oriented contextualist ontologies of art (Levinson) cannot adequately address the problem of work-relativity of modal properties because they understand looseness in what counts as the same context as a view that slight differences in the work-constitutive features of provenance are work-relative. I argue that it is more in the spirit of contextualism to understand looseness as context-dependent. This points to the (...) general problem—the context of appreciation is not robust enough to ground modal intuitions about objective entities. In general, when epistemology dictates ontology there is always a threat of anti-realism, scepticism and relativism. Davies also appeals to the modality principle—an entity’s essential properties are all and only its constitutive properties. Davies understands essentiality in a traditional way: a property P is an essential property of an object o iff o could not exist and lack P. Kit Fine has recently made a convincing case for the view that the notion of essence is not to be understood in modal terms. I explore some of the implications of this view for Davies’ modal argument for the performance theory. (shrink)

Vision is organized around material objects; they are most of what we see. But we also see beams of light, depictions, shadows, reflections, etc. These things look like material objects in many ways, but it is still visually obvious that they are not material objects. This chapter articulates some principles that allow us to understand how we see these ‘ephemera’. H.P. Grice’s definition of seeing is standard in many discussions; here I clarify and augment it with a criterion drawn from (...) Fred Dretske. This enables me to re-analyse certain ephemera that have received counter-intuitive treatments in the work of Kendall Walton (photographs), Brian O’Shaughnessy (light), and Roy Sorenson (occlusions).

El contenido de la presente discusión de Análisis Filosófico surge a partir de diversas actividades organizadas por mí en SADAF y en la UBA. En primer lugar, Roy Cook dictó en SADAF el seminario de investigación intensivo On Yablo's Paradox durante la última semana de julio de 2011. En el seminario, el profesor Cook presentó el manuscrito aún sin finalizar de su libro The Yablo Paradox: An Essay on Circularity, Oxford, Oxford UP, (en prensa). Extensas y apasionantes discusiones ocurrieron durante (...) esos encuentros sobre circularidad y construcciones infinitarias. Fue en ese tiempo, donde me surgió la idea de editar una discusión sobre las ideas que Cook defiende en ese trabajo. El proyecto era una extensión natural del trabajo que veníamos realizando con mi grupo de investigación en temas vinculados al concepto de verdad, autorreferencia y paradojas. Luego, durante el segundo cuatrimestre de 2011, dicté el seminario La paradoja de Yablo, en el instituto de filosofía de la UBA. Algunos de los borradores de los artículos que aparecen en el presente volumen tienen su origen en este curso. Finalmente, invité por segunda vez al profesor Cook al Symposium on Yablo's Paradox realizado en SADAF en julio de 2012. En esta oportunidad, se presentaron las versiones finales de los artículos de Lavinia Picollo, Paula Teijeiro, Federico Pailos, Diego Tajer, Lucas Rosenblatt e Ignacio Ojea que se incluyen a continuación. El encuentro incluyó las inteligentes réplicas del profesor Cook y profundas discusiones sobre los mencionados temas lógicosemánticos. Quiero agradecer a todos los integrantes del Gaf[log] que participaron activamente en las mencionadas actividades, ya sea en la publicación posterior o en los coloquios y seminarios que le dieron origen. Agradezco al Comité editorial de Análisis Filosófico, en especial a Alberto Moretti, quienes apoyaron desde sus comienzos este proyecto. Finalmente, y de manera especial, quiero expresar mi gratitud al profesor Roy Cook, quien no sólo apoyó e inspiró el proyecto desde sus comienzos, sino que además compartió generosamente sus ideas y las discutió con estimulante pasión.

La obra de Yosman Botero siempre ha orbitado entre paradojas. Desde los mismos lugares suplementarios de su obra, como los títulos de sus series Full of Emptiness (2013), Immaterial matter (2014) y Postcolombino (2016) se plantea una encrucijada tanto de la “supervivencia de las imágenes” del arte como de su capacidad comunicativa de la realidad: ya sea esta la experiencia del arte o la realidad social colombiana, o lo que sea que entendemos por “lo real”, tan cara a las propuestas (...) simulacionistas y posapropiacionistas de las décadas del setenta y ochenta. Y digo paradojas porque aquí se juega en los terrenos de una intención inexpresiva ante los procesos de creación de la imagen: Opie, Haring, Negret, Davies, Los Simpsons, Velásquez, o el conflicto colombiano, no son más que el mundo al que Yosman Botero se refiere; pero es un mundo sometido a los procesos de reproducción y mediación cultural, y reflejado en las imágenes.

The exploration of the current understanding the concept of Euro-Islam by researchers is the purpose of this study. To achieve this, we used such methods as analysis and phenomenology. The study analyzed works of the following authors: T. Ramadan, B. Tibi, N. AlSayyad, D. Davydova, L. Koroleva, A. March, A. Mykhal’ova, O. Roy, A. Sadykhova. We have shown that ideas of Euro-Islam have not received widespread support among Muslims in Europe quarter a century after they were expressed by Tariq Ramadan. (...) We also argued that the concept of Euro- Islam has a significant potential to reduce jihadist radicalism in Europe if it is perceived by European Muslims. We have shown that if this concept is adopted by Muslims in Europe, they will turn into a powerful force in the political and social life of Europe. (shrink)

Uno dei principali problemi nello studio della mente e della sua "collocazione" consiste nell'identificazione del corretto Livello di Astrazione a cui le varie descrizioni fenomeniche e le corrispondenti ipotesi esplicative possono essere sviluppate e confrontate. L'articolo contribuisce all'attuale dibattito metodologico in filosofia della mente analizzando due nozioni fondative, quella di modello e quella di simulazione, sulla base del concetto di Livello di Astrazione. L'ambito è quello del Metodo delle Astrazioni, proposto in Floridi e Sanders [2003]. Il Metodo delle Astrazioni si (...) basa su una particolare branca dell'informatica teorica, quella dei Metodi Formali (Roever e Engelhardt [1998]; Woodcock e Davies [1996]), dove la matematica discreta è utilizzata per descrivere analiticamente le specifiche del comportamento di sistemi che elaborano informazioni. I sistemi sono descritti in termini di osservabili e regole di transizione, cioè come sistemi di transizione. Le descrizioni comportano l'utilizzo di variabili che rappresentano osservabili nella realtà, astraendo da altri eventuali osservabili. L'idea di fondo del Metodo delle Astrazioni è che tale processo di filtraggio sia ineliminabile in qualsiasi accesso alla realtà. Il tentativo di sondare un sistema in maggiore profondità produce una maggiore astrazione delle teorie e degli oggetti teorici che descrivono tale sistema. Il Metodo delle Astrazioni si presenta quindi come uno strumento per organizzare e chiarificare le varie teorie che intendono fornire una spiegazione della realtà o della conoscenza. La principale tesi dell'articolo è che "modello" e "simulazione" non possano essere pensati come nozioni a sé stanti, ma che la loro natura possa essere chiarita nei termini di tipi di relazioni tra sistemi di transizione. Nello specifico, si argomenta che la relazione di simulazione è una relazione tra gli osservabili di sistemi di transizione, mentre il modello è una relazione tra le regole di transizione di questi sistemi. Dati questi due nuovi tipi di relazioni, è possibile arricchire con ulteriori strutture di analisi il Metodo delle Astrazioni, estendendo la sua applicabilità. Queste strutture sono discusse nell'articolo come "Reti di Astrazione". (shrink)

This paper reconstructs the function argument of Aristotle’s Eudemian Ethics 2.1. The argument seeks to define happiness through the method of division; shows that the highest good is better than all four of the goods of the soul, not only two, as commentators have thought; and unlike the Nicomachean argument, makes the highest good definitionally independent of the human function.

Immanuel Kant promised, ‘as Your Majesty's loyal subject’, to abstain from all public lectures about religion. All past commentators agree this phrase permitted Kant to return to the topic after the King died. But it is not part of the ‘at-issue content’. Consequently, ‘as Your Majesty's loyal subject’ is no more an escape clause than the corresponding phrase in ‘I guarantee, as your devoted fan, that these guitar strings will not break’. Just as the guarantee stands regardless of whether the (...) guarantor ceases to be your devoted fan, the compliance conditions of Kant's promise are not affected by Kant's ceasing to be the king's loyal subject. For good or ill, Kant made a lying promise to King Friedrich Wilhelm II in 1794. (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.

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)

I introduce a distinction between health need and medical need, and raise several questions about their interaction. Health needs are needs that relate directly to our health condition. Medical needs are needs which bear some relation to medical institutions or processes. I suggest that the question of whether medical insurance or public care should cover medical needs, health needs, or only needs which fit both categories is a political question that cannot be resolved definitionally. I also argue against an overly (...) strict definition of medical need on the grounds that this presupposes, wrongly, that medical intervention should always be a last resort. (shrink)

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

In ‘The Pregnancy Rescue Case: why abortion is immoral’, Hendricks presents The Pregnancy Rescue Case. In this reply I argue that even if it would be better (i.e., less bad) for the abortion to be prevented in The Pregnancy Rescue Case, that does not mean that typical abortions are impermissible. I also argue that there is a possible explanation, consistent with the pro-choice view and empirically testable, as to why people would think it better for the abortion to be prevented (...) in The Pregnancy Rescue Case.

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.

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)

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)

The COVID-19 global pandemic has shone a light on several important ethical questions, ranging from fairness in resource allocation to the ethical justification of government mandates. In addition to these institutional issues, there are also several ethical questions that arise at the interpersonal level. This essay focuses on several of these issues. In particular, I argue that, despite the insistence in public health messaging that avoiding infecting others constitutes ‘saving lives’, virus transmission that results in death constitutes an act of (...) killing. Whether this killing is wrongful depends on several factors. I consider one intuitively plausible view—namely, that in many cases, killing via unintentional transmission is not wrongful, because the parties in question have implicitly waived their rights against this harm, often via reciprocal risk imposition. I argue that this view is mistaken, but that its central insight can be better captured by identifying the appropriate standards of blame that we ought to apply during a pandemic. I conclude by showing how these conclusions can be fruitfully applied to certain institutional questions, such as helping to justify restricting government mandates. (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)

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)

Estonian doesn't have a definite article. Instead, bare singular noun phrases can unambiguously bear either a definite interpretation or an indefinite interpretation. This paper argues that the pragmatic principles governing the felicitous use of three English articles ("a", "the" and "another"), described by A Grønn and KJ Sæbø (2012, 'A, the, another: A game of same and different' Journal of Logic, Language and Information 21, 75-95) can also account for the conditions under which a bare singular noun phrase in Estonian (...) bears a definite or instead an indefinite interpretation. The two languages use the same pragmatic principles to determine the definiteness interpretation of a noun phrase. The difference is just that in English (where definiteness meanings have been lexicalized) these pragmatic principles govern the felicity of article use, whereas in Estonian they govern the interpretation of a bare singular noun phrase.

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.

This research explored the utilization of video-based instructional material in enhancing learning competency among a group of sixty (60) students enrolled in grade 8 at Satriwithaya School in Bangkok, Thailand. The study was carried out. out during the 2nd semester of S.Y. 2023–2024. The respondents were chosen using the approach of purposive sampling. The research study employed an experimental approach and utilized quantitative research. Through the use of of a one-group pre- and post-test, the researcher was able to gather the (...) necessary data. The study included statistical measures such as percentages, means, and standard deviations, as well as dependent and independent t-tests, to assess and compare the proficiency and efficacy of utilizing video-based educational materials among students at Satriwithaya School in Bangkok, Thailand. Study findings also revealed that there is a significant difference in pre- and post-test assessment scores before and after using the video-based instructional materials. The research outcomes indicated that the application of video-based teaching resources as an instructional strategy in the field of biology resulted in an increased degree of effectiveness in the students' learning process. The findings of the study suggest that the utilization of video-based instructional materials has favorable outcomes in terms of enhancing pedagogical and educational achievements in the field of biology. This methodology has been demonstrated to provide learners with with the chance to enhance their comprehension through active participation, cultivate their imagination and cleverness, consequently facilitating enhanced educational achievements. Furthermore, the establishment of a conducive learning atmosphere that is both engaging and pleasurable for students can enhance their overall learning experience. Moreover, this approach enhances the teacher's capacity to convey their intended educational objectives to their students proficiently. -/- . (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.

Utilitarianism has an apparent pedigree when it comes to animal welfare. It supports the view that animal welfare matters just as much as human welfare. And many utilitarians support and oppose various practices in line with more mainstream concern over animal welfare, such as that we should not kill animals for food or other uses, and that we ought not to torture animals for fun. This relationship has come under tension from many directions. The aim of this article is to (...) add further considerations in support of that tension. I suggest three ways in which utilitarianism comes significantly apart from mainstream concerns with animal welfare. First, utilitarianism opposes animal cruelty only when it offers an inefficient ratio of pleasure to pain; while this may be true of eating animal products, it is not obviously true of other abuses. Second, utilitarianism faces a familiar problem of the inefficacy of individual decisions; I consider a common response to this worry, and offer further concerns. Finally, the common utilitarian argument against animal cruelty ignores various pleasures that humans may get from the superior status that a structure supporting exploitation confers. (shrink)

Academic philosophy has a novelty problem. Novelty has become a litmus test for a contribution’s value. This results in a common undertaking for academic researchers. Read a bunch. Look for holes and gaps. Figure out what hasn’t been said. Try to insert yourself in a conversation by saying something new. On first glance, this approach might appear to make sense. If it’s not new, why do we need it? Yet a fixation on novelty sculpts a landscape of philosophical inquiry that (...) is inhospitable and self-undermining. (shrink)

Coleridge rarely mentions Hegel in his philosophical writings and seems to have read very little of Hegel's work. Yet I argue that Coleridge's criticisms of Schelling's philosophy—as recorded in letters and marginalia—betray remarkable intellectual affinities with his nearly exact contemporary Hegel, particularly in their shared doubts about Schelling's foundationalist intuitionism. With this background in place, I seek to demonstrate that volume one of Coleridge's Biographia Literaria is a radically self-undermining text: its philosophical argument, far from slavishly recapitulating Schelling's philosophy, remains (...) haunted by a quasi-Hegelian skepticism toward intuition even as it advances intuition as the foundation of its theoretical edifice.

‘Feminist logic’ may sound like an impossible, incoherent, or irrelevant project, but it is none of these. We begin by delineating three categories into which projects in feminist logic might fall: philosophical logic, philosophy of logic, and pedagogy. We then defuse two distinct objections to the very idea of feminist logic: the irrelevance argument and the independence argument. Having done so, we turn to a particular kind of project in feminist philosophy of logic: Valerie Plumwood's feminist argument for a relevance (...) logic. Plumwood's work serves as our primary case study as we turn to the project of considering three different ways we might understand her argument and revisionist arguments like it: as a priori theorizing, as ameliorative conceptual engineering, or as instances of anti-exceptionalist approaches to logic. After arguing that the anti-exceptionalist approach seems to provide the most promising means of understanding the kind of project undertaken in a feminist challenge to classical logic, we briefly address the consequences that this might have for logic instruction. Here, we argue for the perhaps unexpected conclusion that feminist programs ought to offer more, not less, instruction in logic for those who take interest. (shrink)

Some philosophers and segments of the public think age is relevant to healthcare priority-setting. One argument for this is based in equity: “Old” patients have had either more of a relevant good than “young” patients or enough of that good and so have weaker claims to treatment. This article first notes that some discussions of age-based priority that focus in this way on old and young patients exhibit an ambiguity between two claims: that patients classified as old should have a (...) low priority, and that patients classified as young should have high priority. The author next argues, drawing on a problem raised by Christine Overall, that equity cannot justify giving “old” patients low priority, since there is wide variety in the total lifetime experiences of older people, partly influenced by gender, race, class, and disability injustice. Finally, the author suggests that there might be a limited role for age-based prioritization in the context of infant and childhood death, since those who die in childhood are always and uncontroversially among the worst-off.

According to Essentialism, an object’s properties divide into those that are essential and those that are accidental. While being human is commonly thought to be essential to Socrates, being a philosopher plausibly is not. We can motivate the distinction by appealing—as we just did—to examples. However, it is not obvious how best to characterize the notion of essential property, nor is it easy to give conclusive arguments for the essentiality of a given property. In this paper, I elaborate on these (...) issues and explore the way in which essential properties behave in relation to other related properties, like sufficient-for-existence properties and individual essences.

In this paper we explore the idea that Pentecostalism is best supported by conjoining it to a postmodern, narrative epistemology in which everything is a text requiring interpretation. On this view, truth doesn’t consist in a set of uninterpreted facts that make the claims of Christianity true; rather, as James K. A. Smith says, truth emerges when there is a “fit” or proportionality between the Christian story and one’s affective and emotional life. We argue that Pentecostals should reject this account (...) of truth, since it leads to either a self-refuting story-relativism or the equally problematic fallacy of story-ism: favoring one’s own story over others without legitimate reason. In either case, we contend, the gospel itself is placed at risk. (shrink)

During the Winter of 2011 I visited SADAF and gave a series of talks based on the central chapters of my manuscript on the Yablo paradox.

Many people feel that respecting a person’s autonomy is not sufficiently important to obligate us to stay out of their affairs in all cases; but the ground for interference may often turn out to be a hunch that the agent cannot really be competent, or cannot really know what her decision implies; for if she were both of these things, surely she would not make such a foolish decision. This paper suggests a justification of paternalism that does not rely on (...) such appeals. I argue that in cases where an agent will undergo a significant alteration in their evaluative outlook – ‘evaluative shift’ – three central, persuasive objections to paternalism lose their force, and offer a prima facie case for paternalism in some of these cases. I then suggest that we can extend this argument to some cases where evaluative alteration is not predictable, but where the risk and harm are both significant. In such cases, paternalism may be justified. (shrink)

Subjectivists think that our well-being is grounded in our subjective attitudes. Many such views are vulnerable to variations on the ‘paradox of desire’, where theories cannot make determinate judgements about the well-being of agents who take a positive valuing attitude towards their life going badly. However, this paradox does not affect all subjectivist theories; theories grounded on agents’ prudential values can avoid it.This paper suggests a new paradox for subjectivist theories which has a wider scope, and includes such prudential judgement (...) theories. I outline the new paradox and show how two plausible idealisztions (coherence and consideration) will not help. Subjectivists about well-being must either add an additional idealization that can solve the paradox of judgement or explain why such paradoxes do not constitute serious objections to a theory of well-being.

The paper compares the suitability of two different epistemologies of counterfactuals—(EC) and (W)—to elucidate modal knowledge. I argue that, while both of them explain the data on our knowledge of counterfactuals, only (W)—Williamson’s epistemology—is compatible with all counterpossibles being true. This is something on which Williamson’s counterfactual-based account of modal knowledge relies. A first problem is, therefore, that, in the absence of further, disambiguating data, Williamson’s choice of (W) is objectionably biased. A second, deeper problem is that (W) cannot satisfactorily (...) elucidate modal knowledge. Third, from a naturalistic perspective, the nature of this second problem favours (EC) against (W). (shrink)
