In this paper, I will draw on the capabilities approach to social justice and human development as advanced, among others, by Martha Nussbaum, and seek to provide some theoretical resources for better understanding our obligations to future persons. My argumentative strategy is as follows: First, I’ll briefly reconstruct a capabilities approach to justice, examining this sort of view’s normative foundations and methodology. Using Nussbaum’s capabilities list as a basis, I will argue that various social and environmental functions which are threatened (...) by climate change are crucial with respect to enabling morally and politically central capabilities for both current and future people. Here, I will draw on recent work by Breena Holland to establish the notion of a sustainable climate system as a necessary precondition for the enablement and protection of these entitlements. Then, I’ll extend this strategy to argue that the capabilities approach provides a uniquely useful threshold conception of harm to inform our thinking about our relationship to our posterity. It is my hope that the capabilities approach so applied can give us a novel way of understanding our responsibilities toward future people in a time where such an understanding is both unfortunately lacking and increasingly dire. Finally, I will discuss some implications of a capability-based account in the intergenerational context and some justifications for applying the approach in this way. Ultimately, I submit that this sort of view seems more well-fitted to this context than other approaches (e.g., contractarianism and consequentialism), and that it offers a unique vehicle for understanding our relations and obligations to future people.

Book synopsis: Our mental lives are entwined with the world. There are worldly things that we have beliefs about and things in the world we desire to have happen. We find some things fearsome and others likable. The puzzle of intentionality — how it is that our minds make contact with the world — is one of the oldest and most vexed issues facing philosophers. Many contemporary philosophers and cognitive scientists have been attracted to the idea that our minds represent (...) the world. This book explores an important assumption about representation, namely, that when we represent things in the world, we represent them as having properties, and in this way our representations have "propositional" structure. The contributors examine what the commitment to propositionalism amounts to; illuminate why one might find the thesis attractive ; and consider ways in which one might depart from propositionalism. The hope is that this will lead towards a more complete understanding of how the mind and world are connected. (shrink)

Patient-funded trials are gaining traction as a means of accelerating clinical translation. However, such trials sidestep mechanisms that promote rigor, relevance, efficiency, and fairness. We recommend that funding bodies or research institutions establish mechanisms for merit review of patient-funded trials, and we offer some basic criteria for evaluating PFT protocols.

At the heart of John Broome’s research program in the philosophy of normativity is a distinction between reasons, on one hand, and requirements of rationality, on the other. I am a friend of Broome’s view that this distinction is deep and important, and that neither notion can be analyzed in terms of the other. However, I also think there are major challenges that this view is yet to meet. In the first part of the paper, I’ll raise four such challenges, (...) and programmatically indicate how I think such challenges might be headed off. In the second part of the paper, I’ll discuss a third normative notion that Broome is interested in: that of (rules of) correct reasoning. On Broome’s view, correct reasoning is closely tied to requirements of rationality. More particularly, every rule of correct reasoning corresponds to a “basing permission”, which states that it’s rationally permissible to base one attitude on one or more other attitudes. I’ll argue that this proposal can’t be made to work. If I’m right, this suggests that the same kind of pulling-apart that Broome has effected so persuasively with respect to reasons and requirements of rationality needs to be effected again to separate rules of correct reasoning from both of those other categories.

Semanticists face substitution challenges even outside of contexts commonly recognized as opaque. Jennifer M. Saul has drawn attention to pairs of simple sentences - her term for sentences lacking a that-clause operator - of which the following are typical: -/- (1) Clark Kent went into the phone booth, and Superman came out. (1*) Clark Kent went into the phone booth, and Clark Kent came out. -/- (2) Superman is more successful with women than Clark Kent. (2*) Superman is more successful (...) with women than Superman. -/- She challenges us to explain why the upper and lower sentences in each pair differ, or at least appear to differ, in their truth-values and hence truth-conditions. This appearance of substitution failure is inherently puzzling. Moreover, it is taken by Saul to generate a dilemma for anyone hostile to direct reference accounts of that-clause constructions. Direct reference theorists regard the appearance of substitution failure in that-clause contexts as mere appearance, to be dealt with pragmatically rather than semantically. -/- Critics of such accounts need to say something about simple-sentence cases. If they choose to allow that intuitions of substitution failure can be over-ridden and explained away pragmatically in simple-sentence cases but not in that-clause cases, they lay themselves open to the charge of operating a double standard. But if they do not choose this option, they must offer a semantic explanation of apparent substitution failure in simple-sentence cases - no easy task, it turns out. Other respondents to Saul's challenge have sought to provide elaborate semantic treatments. In contrast, this paper proposes a far simpler pragmatic explanation of intuitions of substitution failure in simple sentences, an explanation that deploys no more resources than are to be found in Grice's 'Logic and Conversation'. Ironically, this proposal turns out to be incompatible with a direct reference perspective. So if it is, as I maintain, the most plausible treatment of simple-sentence cases available, Saul's initial thought gets turned around 180 degrees: the phenomenon she has drawn attention to ends up representing a challenge to supporters of direct reference theories.

Hoerl & McCormack posit two systems – the temporal updating system and the temporal reasoning system – and suggest that they explain an inherent contradiction in people's naïve theory of time. We suggest there is no contradiction. Something does, however, require explanation: the tension between certain sophisticated beliefs about time, and certain phenomenological states or beliefs about those phenomenological states. The temporal updating mechanism posited by H&M may contribute to this tension.

“Avowals” are utterances that “ascribe [current] states of mind”; for instance utterances of ‘I have a terrible headache’ and ‘I’m finding this painting utterly puzzling’ (Bar-On 2004: 1). And avowals, “when compared to ordinary empirical reports…appear to enjoy distinctive security” (1), which Bar-On elaborates as follows: A subject who avows being tired, or scared of something, or thinking that p, is normally presumed to have the last word on the relevant matters; we would not presume to criticize her self-ascription or (...) to reject it on the basis of our contrary judgement. Furthermore, unlike ordinary empirical reports, and somewhat like apriori statements, avowals are issued with a very high degree of confidence and are not easily subjected to doubt. (3) The project of this ambitious, original, and challenging book is to explain why avowals have this distinctive security. Bar-On’s guiding idea is that avowals “can be seen as pieces of expressive behavior, similar in certain ways to bits of behavior that naturally express subjects’ states” (227). Crying and moaning are natural expressions of pain, yawning is a natural expression of tiredness, reaching for beer is a natural expression of the desire for beer, and so on. In some important sense, avowals are supposed to be like that. In what sense, though? It will be useful to begin with the simplest answer. (shrink)

How should we choose between uncertain prospects in which different possible people might exist at different levels of wellbeing? Alex Voorhoeve and Marc Fleurbaey offer an egalitarian answer to this question. I give some reasons to reject their answer and then sketch an alternative, which I call person-affecting prioritarianism.

En 1968 Raquel Carson comenzaba una revolución en el pensamiento, quizá una de las de mayor peso en la actualidad. En su libro "La primavera silenciosa" acusaba del deterioro ambiental al poder ilimitado del ser humano. La creencia surgida en la modernidad de que todo lo que el hombre decidía era en sí mismo lo mejor por haber sido fruto de una voluntad libérrima, daba primacía y legitimidad absoluta a su acción sobre la naturaleza. Surgieron con gran fuerza numerosos (...) grupos ecologistas que adoptaron un pensamiento que responde al nombre de "ecología profunda" o "Deep Ecology" descrito por primera vez por Arme Naess en un artículo publicado por la revista Inquiry y titulado "The Shallow and the Deep, Long Range Ecology Movement". Los principios que proponía este movimiento (Naess 1984) pueden ser resumidos en ocho grandes puntos: 1) la vida de los seres no humanos es un valor en sí: 2) la riqueza y la diversidad de estas formas de vida son también valores en sí; 3) los seres humanos no pueden intervenir de manera destructiva en la vida; 4) a este respecto, la intervención humana actual es eminentemente excesiva; 5) por consiguiente, las reglas de juego deben ser radicalmente modificadas; 6) esta modificación radical debe hacerse tanto a nivel de las estructuras económicas como de las estructuras ideológicas y culturales; 7) a nivel ideológico, el cambio principal consiste en apreciar más la calidad de la vida que el goce de los bienes materiales; 8) las personas que acepten estos principios tienen la obligación de contribuir, directa o indirectamente a la realización de los cambios fundamentales que aquellos implican.

Missing Links, A Book in Ten Sessions received the Award from the Association of Moving Image Researchers [AIM] for Best Monograph released in 2023. -/- Missing Links, A Book in Ten Sessions is Lucas Ferraço Nassif's elaboration on the work of art in Gilles Deleuze and Félix Guattari through description, time, cosmology, and desire production. The films of Chantal Akerman, alongside Anne Carson and Ludwig Wittgenstein, are his main objects of study. -/- //The book is available, open access.// -/- (...) //In Missing Links, Lucas Ferraço Nassif instructs that “cinema exists in the tension of desires, from everything that is in the game”. And “what is in the game vibrates”, or becomes perceptible in the tempo of film and filmic thought that somehow promises to reveal the nature of this world (maybe, a world that’s about to end). To approach such perception is to submit to description, says Nassif, and then proceeds to investigate the act of describing in all its perilous demand and exhausting impossibility. What can we know, after all, of Chantal Akerman’s Jeanne Dielman, at whom we look and look? Or of any seemingly-unified object that, in being worthy of our attention, must be recognized most fundamentally for the way it slips and blurs? I’m dazzled by this writer’s courage to “work on the void”, to tilt, heart in mouth, at ghosts and ruins. This is the drama I came for. — Matt Longabucco// -/- //Inside the cracks in Lucas Ferraço Nassif’s cinecriticism is an elegy for Chantal Akerman, born the same year as me and Anne Carson too, both here hailed. This elegy is composed as a montage that tells the tale of the Jewish filmmaker as desperado fleeing Sherriff Jean-Luc Godard on a runaway midnight train to Rio, which makes an unscheduled stop in Wittgenstein, Montana. What with all the humming, you just can’t see it. Or if you can, you can’t describe it. “We have nowhere else to start.” — Charles Bernstein// -/- //Lucas Ferraço Nassif’s expansive, rhizomatic project is “full” of missing links in the sense of plenitude: a surfeit of references, genres, affects, and paths for the reader to follow, the listener to harken, the viewer to watch. In the process of tracing affinities between the cast of characters in the intellectual drama staged here — from Jean-Luc Godard to Ludwig Wittgenstein, Anne Carson to Chantal Akerman, Gilles Deleuze to Jacques Lacan, and beyond — we have the chance to reconsider the articulations and boundaries, the flows and stoppages, between film and writing, autobiography and criticism, theory and practice. Missing Links is a ciné-poème of flickering, delicate attention that compels our immersion in turn. — Craig Dworkin//. (shrink)

RELAÇÃO E EFEITOS BIOQUÍMICO-NUTRICIONAIS SOBRE A METRITE EM VACAS -/- Emanuel Isaque Cordeiro da Silva Departamento de Agropecuária – IFPE Campus Belo Jardim [email protected] ou [email protected] WhatsApp: (82)98143-8399 -/- •__3. METRITE -/- O transtorno caracterizado pela inflamação do útero, devido a causas sépticas ou assépticas que atuam sobre ele, denomina-se genericamente como metrite. As metrites são afecções de grande importância, tanto pela frequência como pela gravidade. As metrites podem ser divididas segundo seu caráter anatômico, como mucosa (catarral), purulenta, hemorrágica, crupal, (...) pútrida e flegmonosa e segundo seu curso, em agudas e crônicas (FRAZER, 2005; GORDON, 1996). Estão associadas às doenças do puerpério. Quando a inflamação é limitada à mucosa é chamada de endometrite; e se ademais interessa a camada muscular denomina-se metrite ou miometrite; se afeta o revestimento peritoneal, perimetrite ou metroperitonite; e se a inflamação se estende ao paramétrio, ou seja, ao tecido conjuntivo pélvico e ligamentos, chama-se parametrite (FÖLDI, et al. 2006). A metrite ocorre em consequência de diversos acidentes que resultam de partos distócicos, após retenção fetal ou secundinas seguidas de putrefação, por arrancamento brutal dos cotilédones; por injeções uterinas irritantes; após o prolapso uterino; tudo o que favorece o desenvolvimento microbiano. Em fêmeas que se inseminam artificialmente sob condições sépticas ou de pobre destreza se produz endometrite seguida com infecundidade passageira, isto se produz como consequência das erosões produzidas pela pistola de inseminação, desassossego geral no procedimento ou por levar o sêmen a maior temperatura que a devida e em lugar inadequado. Algumas situações de origem nutricional se associam em maior ou menor grau com a incidência de metrite, em especial processos de retenção de placenta ou involução uterina de origem nutricional podem levar, de forma indireta, a incidência de metrite. 3.1 Relação energia e proteína Uma das situações de origem nutricional associada à metrite é o excesso de proteína crua na dieta. As vacas necessitam de um adequado fornecimento de proteína. No afã de suprir as necessidades nutricionais e evitar as limitações de aminoácidos, cai-se no erro de fornecer excessos de proteína, trazendo como consequência uma diminuição da eficiência reprodutiva, devido à relação dos altos níveis de proteína na dieta com a falha reprodutiva específica. Um excesso de proteína resulta num aumento da produção de amoníaco e, como consequência, numa maior síntese de ureia pelo fígado (BACH, 2000). Consequentemente, existe um aumento do nível de ureia no sangue, no útero e no muco vaginal. A nível uterino, a ureia parece ter um efeito sobre a função hormonal e depressora da proteção imunitária. O mecanismo específico baseia-se na toxicidade direta da ureia, na perda do balanço energético e na concentração de diaminas de ácido carbônico que favorecem a ampla difusão da ureia em todo o endométrio. O fornecimento de fontes alternativas de nitrogênio na alimentação dos animais vêm ganhando espaço no debate entre os especialista e a ureia é uma dessas fontes. Ela é conhecida como uma fonte de nitrogênio não-proteico (NNP), porém não se destaca tanto pelos inúmeros fatores negativos como a baixa aceitabilidade dos animais ou aos índices de intoxicação pela mesma. O rúmen necessita de um teor de 1% de nitrogênio para manter os mecanismos fisiológicos e a população microbiana, sendo assim, o produtor deve estar atento ao fornecimento desse mineral para seus animais. Especialistas apontam a fórmula de 30 g de ureia por dia para animais de 100 kg, e que essa quantidade nunca pode exceder os 200 g por animal por dia. Esses dados só podem ser postos em prática se as forrageiras existentes na propriedade não conseguirem suprir a exigência de 1% de nitrogênio no animal. Uma fonte vegetal de ótima qualidade e abundante em meios nutricionais e fonte extra de renda é a cana-de-açúcar. Ao nível hormonal a presença de ureia impede a manutenção do gradiente de pH (induzido pela progesterona) que existe entre as células apicais e basais da parede uterina (MARÍN & CÁRDENAS, 1999). Assim, a progesterona não consegue manter o gradiente de pH e aumenta a secreção de PGF2α, que afeta negativamente tanto a sobrevivência como o desenvolvimento embrionário. A nível imunológico, ocorre um efeito negativo devido à elevada concentração de amônio e ureia no sangue, o que diminui a atividade dos linfócitos e impede a defesa celular contra os agentes nocivos provocadores da metrite infecciosa, favorecendo o desenvolvimento microbiano. Para determinar a quantidade e a qualidade da nutrição proteica do animal são utilizados indicadores como a concentração de ureia no sangue e no leite. As proteínas, em geral, possuem inúmeras funções, dentre elas componentes estruturais, funções enzimáticas, funções hormonais, recepção de estímulos hormonais e armazenamento de informações genéticas. Na nutrição animal, as proteínas são divididas entre bruta (PB) e metabolizável (PM), ainda outras, mas o enfoque são essas. Os animais necessitam de níveis distintos de proteínas em suas respectivas fases de vida. Para elucidar melhor, tomemos como exemplo uma vaca nelore de 420 kg no final da gestação necessita, em média, de 389 g/dia de proteína metabolizável e, em média de 581 g/dia de proteína bruta. Os alimentos de origem vegetal (forrageiras) fornecem muito bem e eficazmente teores aceitáveis de proteínas, porém como o elemento mais presente é a fibra, faz-se necessário a suplementação nos animais, e um meio de suprir as necessidades dos mesmo, é optando por farelos de soja que possuem mais de 60% de proteína em sua composição, ou outras fontes alternativas como as farinhas de origem animal como a de sangue, por exemplo. A deficiência de fibra crua desencadeia principalmente uma deficiência de energia no ruminante; pois a partir da fibra formam-se os ácidos graxos voláteis (AGV) que constituem até 60% das fontes energéticas para estes animais. Devido à síntese reduzida de AGV, é muito baixa a concentração destes, são absorvidos pela corrente sanguínea e o animal entra em estado de déficit de precursores glicogênios. Como o consumo de alimento no pós-parto está reduzido, e não há a suficiente disposição de energia (deficiência de AGV principalmente ácido acético, devido a deficiência em fibra crua), o organismo realiza uma mobilização de ácidos graxos para a compensação energética. Os ácidos graxos são levados até acetil-CoA, este é convertido pelo fígado em corpos cetônicos que são utilizados em baixa concentração por alguns tecidos periféricos (cérebro) como fonte de energia, pois os excessos de corpos cetônicos produzem toxicidade. Os excessos de acetil-CoA no fígado podem sofrer condensação e converterem-se em β-hidroxi-β-metil-glutaril-CoA que serve como fonte de mevalonato (precursor do colesterol formado em excesso). Os excessos provocam fígado graxo que gera danos hepáticos, isso deprime a síntese de ácidos graxos para a formação do colesterol que se encontra diretamente implicado na síntese de estrogênios. Após o parto uma deficiência de estrogênio provoca de forma subsequente atonia uterina, retenção de placenta, endometrite puerperal e finalmente metrite. 3.2 Vitaminas Outra causa nutricional que incide na manifestação de metrite, é a vitamina A, que faz parte do grupo de vitaminas lipossolúveis e tem relevância especial na função reprodutiva. Esta exerce sua ação sobre a integridade estrutural e funcional das células epiteliais do organismo animal, atua sobre o crescimento, a reprodução e o desenvolvimento embrionário; mas seu papel principal é atuar como protetora dos epitélios, incluindo o endométrio. Além disso, tem um efeito estabilizador sobre várias membranas celulares e atua regulando a permeabilidade da membrana. A vitamina A, atua como estimuladora dos epitélios da mucosa tubária, uterina e vaginal, aumentando sua resistência contra os agentes infecciosos que produzem problemas que finalizam em metrite, também é necessária para as alterações histológicas que ocorrem na mucosa durante as diferentes fases do ciclo estral. Uma deficiência de vitamina A, pode causar morte embrionária, aborto, bezerros fracos ao nascimento e de forma subsequente uma retenção de placenta, (BACH, 2000) devido a não regulação da filtração de líquidos e gases através das membranas fetais; também dificulta a fecundação, devido à geração de uma atresia ovariana e à degeneração do epitélio germinal. Além disso, são produzidos edemas que ocasionam bezerros mortos ou prematuros (natimortos), o que provoca uma posterior retenção de placenta. Estas retenções provocam metaplasia queratinizam-te, dos epitélios da mucosa uterina-vaginal, o que provoca o aparecimento de metrite. Também, uma deficiência de outras vitaminas provocam o aparecimento de pequenas hemorragias, inchaço vulvar e degeneração epitelial das mucosas, em geral, isto provoca uma endometrite que posteriormente torna-se em metrite devido ao que se afeta a submucosa e a camada muscular do útero. Em relação ao pós-parto precoce, a capacidade de consumo de alimentos (forragem) é limitada, o que conduz, principalmente, a uma deficiência de fibras cruas na ruminação do animal, que conduzirá, em algumas circunstâncias, à predisposição para o desenvolvimento de metrite. Atentos a essas intempéries, o produtor deve estar atento aos requerimento exigidos pelos animais de vitaminas para que possam manter seu funcionamento normal e longe de quaisquer problema ou agente infeccioso ou patógeno. Para tanto, os níveis de vitaminas por categoria animal, deve prezar pelas quantidades conforme demonstrado nas tabelas abaixo: Tabela 1: Exigências de vitaminas por categoria animal em bovinos de corte -/- Categoria Vitamina A (UI/dia) Vitamina E (mg/dia) Vitamina D (UI/dia) Niacina (g/dia) Vacas lactantes 80.000 – 120.000 100 – 1.000 15.000 – 50.000 1 - 2 Vacas secas 75.000 – 125.000 500 – 900 10.000 – 20.000 0 – 1 Fonte: BERCHIELLI et al., 2006. Tabela 2: Exigências de vitaminas em vacas gestantes de corte -/- Vitamina UI/kg de MS A 2.800 D 275 Fonte: BERCHIELLI et al., 2006. Para que se consiga suprir todas essas quantidades requeridas dos animais, em especial, das vacas gestantes para que não venha a ocorrer a incidência de metrite ou outro transtorno reprodutivo, o criador poderá optar pela injeção direta de complexos vitamínicos e minerais mediante os inúmeros fármacos da indústria farmacêutica animal, ou poderá suprir essas necessidades fisiológicas mediante o fornecimento de rações com teores adequados de vitaminas, ou ainda por intermédio de alimentos volumosos que além das vitaminas necessárias fornecem também as fibras. As forrageiras, leguminosas e gramíneas fornecem minerais, fibras e vitaminas; dentre elas as espécies tifton (capim) apresenta cerca de 34,8% de vitamina A, o capim-tanzânia apresenta 24% e a alfafa 23,4%. Por fim, métodos para fornecimento de fibras, vitaminas e/ou minerais não faltam. Apoio -/- Realização •_ _referências bibliográficas -/- BACH, Alex; ESPAÑA, Purina.

Automatic detection of diseases and anatomical landmarks in medical images by the use of computers is important and considered a challenging process that could help medical diagnosis and reduce the cost and time of investigational procedures and refine health care systems all over the world. Recently, gastrointestinal (GI) tract disease diagnosis through endoscopic image classification is an active research area in the biomedical field. Several GI tract disease classification methods based on image processing and machine learning techniques have been proposed (...) by diverse research groups in the recent past. However, yet effective and comprehensive deep ensemble neural network-based classification model with high accuracy classification results is not available in the literature. In this thesis, we review ways and mechanisms to use deep learning techniques to research on multi-disease computer-aided detection about gastrointestinal and identify these images. We re-trained five state-of-the-art neural network architectures, VGG16, ResNet, MobileNet, Inception-v3, and Xception on the Kvasir dataset to classify eight categories that include an anatomical landmark (pylorus, z-line, cecum), a diseased state (esophagitis, ulcerative colitis, polyps), or a medical procedure (dyed lifted polyps, dyed resection margins) in the Gastrointestinal Tract. Our models have showed results with a promising accuracy which is a remarkable performance with respect to the state-of-the-art approaches. The resulting accuracies achieved using VGG, ResNet, MobileNet, Inception-v3, and Xception were 98.3%, 92.3%, 97.6%, 90% and 98.2%, respectively. As it appears, the most accurate result has been achieved when retraining VGG16 and Xception neural networks with accuracy reache to 98% due to its high performance on training on ImageNet dataset and internal structure that support classification problems.

Totalism is the view that one distribution of well-being is better than another just in case the one contains a greater sum of well-being than the other. Many philosophers, following Parfit, reject totalism on the grounds that it entails the repugnant conclusion: that, for any number of excellent lives, there is some number of lives that are barely worth living whose existence would be better. This paper develops a theory of welfare aggregation—the lexical-threshold view—that allows totalism to avoid the repugnant (...) conclusion, as well as its analogues involving suffering populations and the lengths of individual lives. The theory is grounded in some independently plausible views about the structure of well-being, identifies a new source of incommensurability in population ethics, and avoids some of the implausibly extreme consequences of other lexical views, without violating the intuitive separability of lives.

Matthew Adler's Measuring Social Welfare is an introduction to the social welfare function (SWF) methodology. This essay questions some ideas at the core of the SWF methodology having to do with the relation between the SWF and the measure of well-being. The facts about individual well-being do not single out a particular scale on which well-being must be measured. As with physical quantities, there are multiple scales that can be used to represent the same information about well-being; no one scale (...) is special. Like physical laws, the SWF and its ranking of distributions cannot depend on exactly which of these scales we use. Adler and other theorists in the SWF tradition have used this idea to derive highly restrictive constraints on the shape of the SWF. These constraints rule out seemingly plausible views about distributive justice and population ethics. I argue, however, that these constraints stem from a simple but instructive mistake. The SWF should not be applied to vectors of numbers such as 1 and 2, but rather to vectors of dimensioned quantities such as 1 util and 2 utils. This seemingly pedantic suggestion turns out to have far-reaching consequences. Unlike the orthodox SWF approach, treating welfare levels as dimensioned quantities lets us distinguish between real changes in well-being and mere changes in the unit of measurement. It does this without making the SWF depend on the scale on which welfare is measured, and in a way that avoids the restrictive constraints on the shape of the SWF. (shrink)

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

Lara Buchak argues for a version of rank-weighted utilitarianism that assigns greater weight to the interests of the worse off. She argues that our distributive principles should be derived from the preferences of rational individuals behind a veil of ignorance, who ought to be risk averse. I argue that Buchak’s appeal to the veil of ignorance leads to a particular way of extending rank-weighted utilitarianism to the evaluation of uncertain prospects. This method recommends choices that violate the unanimous preferences of (...) rational individuals and choices that guarantee worse distributions. These results, I suggest, undermine Buchak’s argument for rank-weighted utilitarianism. (shrink)

ABSTRACT The idea that two words can be instances of the same word is a central intuition in our conception of language. This fact underlies many of the claims that we make about how we communicate, and how we understand each other. Given this, irrespective of what we think words are, it is common to think that any putative ontology of words, must be able to explain this feature of language. That is, we need to provide criteria of identity for (...) word-types which allow us to individuate words such that it can be the case that two particular word-instances are instances of the same word-type. One solution, recently further developed by Irmak, holds that words are individuated by their history. In this paper, I argue that this view either fails to account for our intuitions about word identity, or is too vague to be a plausible answer to the problem of word individuation. (shrink)

Many say that ontological disputes are defective because they are unimportant or without substance. In this paper, we defend ontological disputes from the charge, with a special focus on disputes over the existence of composite objects. Disputes over the existence of composite objects, we argue, have a number of substantive implications across a variety of topics in metaphysics, science, philosophical theology, philosophy of mind, and ethics. Since the disputes over the existence of composite objects have these substantive implications, they are (...) themselves substantive. (shrink)

There is more than one way to say that composition is identity. Yi has distinguished the Weak Composition thesis from the Strong Composition thesis and attributed the former to David Lewis while noting that Lewis associates something like the latter with me. Weak Composition is the thesis that the relation between the parts collectively and their whole is closely analogous to identity. Strong Composition is the thesis that the relation between the parts collectively and their whole is identity. Yi is (...) right that Strong Composition does not fully reflect my view. We must recognize further what, borrowing Lewis's characterization, could be called the "stronger, and stranger" Composition thesis, or what I'll call the Stronger Composition thesis for short. On Strong Composition, it is only collectively that the parts are identical with the whole. On Stronger Composition, they are individually identical with it as well. I will explain and motivate this thesis. (shrink)

According to asymmetric comparativism, it is worse for a person to exist with a miserable life than not to exist, but it is not better for a person to exist with a happy life than not to exist. My aim in this paper is to explain how asymmetric comparativism could possibly be true. My account of asymmetric comparativism begins with a different asymmetry, regarding the (dis)value of early death. I offer an account of this early death asymmetry, appealing to the (...) idea of conditional goods, and generalize it to explain how asymmetric comparativism could possibly be true. I also address the objection that asymmetric comparativism has unacceptably antinatalist implications. (shrink)

Empirical philosophers of science aim to base their philosophical theories on observations of scientific practice. But since there is far too much science to observe it all, how can we form and test hypotheses about science that are sufficiently rigorous and broad in scope, while avoiding the pitfalls of bias and subjectivity in our methods? Part of the answer, we claim, lies in the computational tools of the digital humanities, which allow us to analyze large volumes of scientific literature. Here (...) we advocate for the use of these methods by addressing a number of large-scale, justificatory concerns—specifically, about the epistemic value of journal articles as evidence for what happens elsewhere in science, and about the ability of DH tools to extract this evidence. Far from ignoring the gap between scientific literature and the rest of scientific practice, effective use of DH tools requires critical reflection about these relationships. (shrink)

This paper offers a positive account of an important but under-explored class of mental states, non-propositional attitudes such as loving one’s department, liking lattice structures, fearing Freddy Krueger, and hating Sherlock Holmes. In broadest terms, the view reached is a representationalist account guided by two puzzles. The proposal allows one to say in an elegant way what differentiates a propositional attitude from an attitude merely about a proposition. The proposal also allows one to offer a unified account of the non-propositional (...) attitudes that captures both empty and non-empty cases by properly locating the posited representations in the metaphysical structure of the attitudes.

We defend three controversial claims about preference, credence, and choice. First, all agents (not just rational ones) have complete preferences. Second, all agents (again, not just rational ones) have real-valued credences in every proposition in which they are confident to any degree. Third, there is almost always some unique thing we ought to do, want, or believe.

We study the question of how to decompose Hilbert space into a preferred tensor-product factorization without any pre-existing structure other than a Hamiltonian operator, in particular the case of a bipartite decomposition into "system" and "environment." Such a decomposition can be defined by looking for subsystems that exhibit quasi-classical behavior. The correct decomposition is one in which pointer states of the system are relatively robust against environmental monitoring (their entanglement with the environment does not continually and dramatically increase) and remain (...) localized around approximately-classical trajectories. We present an in-principle algorithm for finding such a decomposition by minimizing a combination of entanglement growth and internal spreading of the system. Both of these properties are related to locality in different ways. This formalism could be relevant to the emergence of spacetime from quantum entanglement. (shrink)

In this paper, I defend the view that it is wrong for us to consume only, or overwhelmingly, media that broadly aligns with our own political viewpoints: that is, it is wrong to be politically “partisan” in our decisions about what media to consume. We are obligated to consume media that aligns with political viewpoints other than our own – to “diversify our sources”. This is so even if our own views are, as a matter of fact, substantively correct.

In her black and white room, Mary doesn’t know what it is like to see red. Only after undergoing an experience as of something red and hence acquainting herself with red can Mary learn what it is like. But learning what it is like to see red requires more than simply becoming acquainted with it. To be acquainted with something is to know it, but such knowledge, as we argue, is object-knowledge rather than propositional-knowledge. To know what it is like (...) one must know an appropriate propositional answer to the question ‘what is it like?’. Despite this mismatch between object-knowledge and knowing an answer, we believe that acquaintance is crucial to Mary’s epistemic progress. When Mary leaves her black and white room, her new knowledge tempts one to think that she must come to know a candidate answer (a coarse-grained fact) that she didn’t know in her room. Since Mary already knows all the physical facts in her room, any additional facts she might learn appear to threaten physicalism. In reply, many physicalists have been attracted to the phenomenal concept strategy according to which Mary can come to have new knowledge and hence know a new answer to the question ‘what is it like to see red?’ by entertaining a coarse-grained fact under a concept she didn’t possess in her room – Mary learns a new fine-grained fact. We believe both of these accounts of Mary’s epistemic progress are mistaken. As we argue, Mary could know every fact (coarse-grained and fine-grained) that might serve as an answer to the question ‘what is it like to see red?’ and still not know what it is like. The physical world leaves no leftover coarse-grained facts for Mary to learn and because concepts are sharable, easy to possess, and easy to introduce, there are possible situations in which Mary, while in her black and white room, has every concept that might make a fine-grained difference. In short, even when Mary is granted a great deal of factual knowledge and vast conceptual resources, she may still not know an appropriate answer to the question ‘what is it like to see red?’. But in any such situation, Mary lacks acquaintance with red and on this basis we argue that in order to know what it is like, in order for Mary to know an appropriate answer, Mary’s propositional knowledge must be appropriately related to her acquaintance with red.

This paper takes as its point of departure recent research into the possibility that human beings can perceive single photons. In order to appreciate what quantum perception may entail, we first explore several of the leading interpretations of quantum mechanics, then consider an alternative view based on the ontological phenomenology of Maurice Merleau-Ponty and Martin Heidegger. Next, the philosophical analysis is brought into sharper focus by employing a perceptual model, the Necker cube, augmented by the topology of the Klein bottle. (...) This paves the way for addressing in greater depth the paper’s central question: Just what would it take to observe the quantum reality of the photon? In formulating an answer, we examine the nature of scientific objectivity itself, along with the paradoxical properties of light. The conclusion reached is that quantum perception requires a new kind of observation, one in which the observer of the photon adopts a concretely self-reflexive observational posture that brings her into close ontological relationship with the observed.

A. Newell and H. A. Simon were two of the most influential scientists in the emerging field of artificial intelligence (AI) in the late 1950s through to the early 1990s. This paper reviews their crucial contribution to this field, namely to symbolic AI. This contribution was constituted mostly by their quest for the implementation of general intelligence and (commonsense) knowledge in artificial thinking or reasoning artifacts, a project they shared with many other scientists but that in their case was theoretically (...) based on the idiosyncratic notions of symbol systems and the representational abilities they give rise to, in particular with respect to knowledge. While focusing on the period 1956-1982, this review cites both earlier and later literature and it attempts to make visible their potential relevance to today's greatest unifying AI challenge, to wit, the design of wholly autonomous artificial agents (a.k.a. robots) that are not only rational and ethical, but also self-conscious.

A standard view in philosophy is that knowledge entails justification. Yet recent research suggests otherwise. We argue that this admirable and striking research suffers from an important limitation: participants were asked about knowledge but not justification. Thus it is possible that people attributed knowledge partly because they thought the belief was justified. Perhaps though, if given the opportunity, people would deny justification while still attributing knowledge. It is also possible that earlier findings were due to perspective taking. This paper reports (...) further research that directly addresses these questions. Our findings support the hypothesis that knowledge entails justification on the ordinary view. (shrink)

Genera, typically hand-in-hand with their branching species, are essential elements of vocabulary-based information constructs, in particular scientific taxonomies. Should they also feature in formal ontologies, the highest of such constructs? I argue in this article that the answer is “Yes” and that the question posed in its title also has a Yes-answer: The way medieval ontologists sliced up the world into genera does matter to formal ontology. More specifically, the way Dietrich of Freiberg, a Latin scholastic, conceived and applied strictly (...) generic criteria to slice up the world into its entities can provide some guidelines to the field of formal ontology with respect to not only its contents, but also its scope. In particular, Dietrich's information criterion plays here a central role. (shrink)

An analysis of--yet another--case of academic failure in multi- and interdisciplinarity. An editorial of the Journal of Knowledge Structures & Systems.

Doxasticism is the thesis that intention is or involves belief in the forthcoming action (Velleman, Harman). Supporters claim that it is only by accepting that thesis that we can explain a wide array of important phenomena, including the special knowledge we have of intentional action, the roles intention plays in facilitating coordination, and the norms of rationality for intention. Others argue that the thesis is subject to counterexample (Davidson, Bratman). Yet some others contend that the thesis can be reformulated in (...) a way that avoids such counterexamples and preserves its explanatory significance (Pears, Setiya). Their suggestion is that we view intention as involving partial –rather than full—belief. I argue that while the move from full to partial doxasticism helps to accommodate such counterexamples, it does so in a way that undermines the ability of the resulting view to explain the coordinating roles of and rationality norms for intention.

Public justification in political liberalism is often conceptualized in light of Rawls’s view of its role in a hypothetical well-ordered society as an ideal or idealizing form of justification that applies a putatively reasonable conception of political justice to political matters. But Rawls implicates a different idea of public justification in his doctrine of general reflective equilibrium. The paper engages this second, more fundamental idea. Public justification in this second sense is actualist and fundamental. It is actualist in that it (...) fully enfranchises actual reasonable citizens. It is fundamental in that political liberalism qualifies conceptions of political justice as reasonable to begin with only if they can be accepted coherently by actual reasonable citizens. Together, these features invite the long-standing concern that actualist political liberalism is objectionably exclusionary. I argue that the exclusion objection, while plausible, is more problematic in own right than it seems if actualist and fundamental public justification hypotheticalizes and discursive respect is compatible with substantive discursive inequality. This leaves proponents and critics of political liberalism with deeper questions about the nature of permissible discursive inequality in public justification. (shrink)

In this article, I distinguish two models of personal integrity. The first, wholeheartedness, regards harmonious unity of the self as psychologically healthy and volitional consistency as ethically ideal. I argue that it does so at the substantial cost of framing ambivalence and conflict as defects of character and action. To avoid these consequences, I propose an alternate ideal of humility that construes the self as multiple and precarious and celebrates experiences of loss and transformation through which learning, growth, innovation, and (...) dynamic relationship become possible. This ideal not only sustains prospects for integrity but is more suitable than wholeheartedness for recognizing practices of contestation, such as those involving potentially destabilizing encounters with difference that is common within pluralistic societies, as vital for rich, well-lived lives.

To understand what non-propositional content is and whether there are any such contents, we first need to know what propositional content is. That issue will be the focus of the first section of this essay. In the second section, with an understanding of propositional content in hand, we will consider representations that fail to have propositional content. In contrast to recent literature, it will be argued that metaphysical considerations concerning what's represented, rather than linguistic considerations, are a more promising way (...) of establishing non-propositional contents. To keep the discussion containable, focus will be on representational mental states, though many of the considerations can be extended to other forms of representation. (shrink)

Historically, the concept of androgyny has been as problematic as it has been appealing to Western progressives. The appeal clearly includes, inter alia, the opportunity to abandon or ameliorate certain identities. As for the problematic dimension, the central problem seems to be the reduction of otherness to the norms of straight white middle/upper-class Western cismen, particularly because of the consequent worsening of actual others’ marginalization and exclusion from social institutions. Despite these problems, I wish to suggest that androgyny—as evidenced by (...) the enthusiasm felt for it by many Westerners—bespeaks something larger and more important than the concept itself, and that modified conception of it might be helpful in pursuit of social justice.

The remaining seven papers (eight, if you count this introductory piece) in this volume of Oxford Studies in Epistemology constitute a special issue on applied epistemology, an exciting, novel, and currently burgeoning subfield of epistemology. The term ‘applied epistemology’ is a relatively recent one, however, and anecdotally, many people I’ve encountered are not quite sure what it denotes, or what different works within the field have in common. In this introductory piece, I’ll venture some views about these questions, and about (...) why applied epistemology is worth doing, as well as about its dangers. Doing so will set the state for me to situate the papers in this volume within the subfield. (shrink)

This chapter starts from the claim that the state is plagued with problems of political short-termism: excessive priority given to near-term benefits at the expense of benefits further in thefuture. One possible mechanism to reduce short-termism involves apportioning greater relative political influence to the young, since younger citizens generally have greater additional life expectancy than older citizens and thus it looks reasonable to expect that they have preferences that are extended further into the future. But the chapter shows that this (...) is unlikely to make states significantly less short-termist: no empirical relationship has been found between age and willingness to support long-termist policies. Instead, the chapter proposes a more promising age-based mechanism. States should develop youth citizens’ assemblies that ensure accountability to future generations through a scheme of retrospective accountability. (shrink)

In this paper I highlight two noteworthy features of assertions about our desires, and then highlight two ways in which they can mislead us into drawing unwarranted conclusions about desire.

But I suggest that some such assertions are, in this respect, potentially misleading, and have in fact misled authors such (...) as Russ Shafer-Landau, Jack Woods, and Tim Scanlon. (shrink)

The host of SUSY(supersymmetry) based string theories is considered. Superstrings are comprehended as possible candidates on Quantum Gravity basic objects. It is argued that superstring theories constitute mainly mathematical progress and can reconcile general relativity with quantum field theory at best. Yet they cannot provide the genuine synthesis. Superstring unification of all the four forces at hand is a formal one . It is contended that genesis and proliferation of superstrings can better be described not by philosophy of science models (...) but in terms of modern sociology of science. The formal character of gravity and quantum fields fusion and the lack of experimental verification make the transition to superstring theories ad hoc in Lakatosian standards. Possible way of explanation is proposed based on social interests conception of Andrew Pickering. -/- Key words: superstrings, unification, Kaluza-Klein, sociology of science . (shrink)

Many believe that we ought to save a large number from being permanently bedridden rather than save one from death. Many also believe that we ought to save one from death rather than a multitude from a very minor harm, no matter how large this multitude. I argue that a principle I call “Aggregate Relevant Claims” satisfactorily explains these judgments. I offer a rationale for this principle and defend it against objections.

Special Relativity and the Early Quantum Theory were created within the same programme of statistical mechanics, thermodynamics and maxwellian electrodynamics reconciliation. I shall try to explain why classical mechanics and classical electrodynamics were “refuted” almost simultaneously or, in more suitable for the present congress terms, why did quantum revolution and the relativistic one both took place at the beginning of the 20-th century. I shall argue that quantum and relativistic revolutions were simultaneous since they had common origin - the clash (...) between the fundamental theories of the second half of the 19-th century that constituted the “body” of Classical Physics. The revolution’ s most dramatic point was Einstein’s 1905 photon paper that laid the foundations of both Special Relativity and Old Quantum Theory. Hence the dialectic of the old theories is crucial for theory change. Modern physics began with Einstein’s reconciliation of electrodynamics, mechanics and thermodynamics in 1905 and his unification of Special Relativity and Newtonian Theory of Gravity. Or, in more general social context: progressive scientific change can be described not in Weberian terms of zweckrational action forcing out all the other forms of action only but in terms of Habermas’s communicative rationality encouraging the establishment of mutual understanding between the various scientific communities also. Einstein’s programme constituted a progressive step in respect to its rivals not because it could explain more “facts” or was more “mathematical”. It was high than its rivals because it constituted a basis of communication and interpenetration between three main paradigms of 19-th century physics. Of course in the long run it resulted in empirical successes. Key words: Einstein, scientific revolution, communicative rationality. (shrink)

Recently several authors have argued that accuracy-first epistemology ends up licensing problematic epistemic bribes. They charge that it is better, given the accuracy-first approach, to deliberately form one false belief if this will lead to forming many other true beliefs. We argue that this is not a consequence of the accuracy-first view. If one forms one false belief and a number of other true beliefs, then one is committed to many other false propositions, e.g., the conjunction of that false belief (...) with any of the true beliefs. Once we properly account for all the falsehoods that are adopted by the person who takes the bribe, it turns out that the bribe does not increase accuracy. (shrink)

We present a preliminary high-level formal theory, grounded on knowledge representation techniques and foundational ontologies, for the uniform and integrated representation of the different kinds of (quali- tative and quantitative) knowledge involved in the designing process.

These notions are then formally charac- terized by extending the DOLCE foundational ontology. Our ultimate purpose is twofold: (i) to contribute to foundational issues of design; and (ii) to support (...) the development of advanced modelling systems for (qualitative and quantitative) representation of design knowledge.

In this paper I argue that both defence and criticism of the claim that humans act ‘under the guise of the good’ neglects the metaphysical roots of the theory. I begin with an overview of the theory and its modern commentators, with critics noting the apparent possibility of acting against the good, and supporters claiming that such actions are instances of error. These debates reduce the ‘guise of the good’ to a claim about intention and moral action, and in so (...) doing have become divorced from the theory's roots in classical and medieval philosophy. Aristotle and Aquinas’ ‘guise of the good’ is primarily a metaphysical claim resting on the equivalence between actuality and goodness, from which conclusions about moral action are derived. I show the reasoning behind their theory and how it forms the basis for the claims about intention and action at the centre of the modern debate. Finally, I argue that the absence of its original foundation is apparent in recent attacks on the ‘guise of the good’. It is unsurprising that modern action theory and ethics have not always been able to comfortably accommodate the ‘guise of the good’; they are only telling half of the story. (shrink)
