Different authors offer subtly different characterizations of naïve realism. We disentangle the main ones and argue that illusions provide the best proving ground for naïve realism and its main rival, representationalism. According to naïve realism, illusions never involve per- ceptual error. We assess two leading attempts to explain apparent perceptual error away, from William Fish and Bill Brewer, and conclude that they fail. Another lead- ing attempt is assessed in a companion paper, which also sketches an alternative representational account.

Temporal non-dynamists hold that there is no temporal passage, but concede that many of us judge that it seems as though time passes. Phenomenal Illusionists suppose that things do seem this way, even though things are not this way. They attempt to explain how it is that we are subject to a pervasive phenomenal illusion. More recently, Cognitive Error Theorists have argued that our experiences do not seem that way; rather, we are subject to an error that leads us mistakenly (...) to believe that our experiences seem that way. Cognitive Error Theory is a relatively new view and little has been said to explain why we make such an error, or where, in the cognitive architecture, such an error might creep in. In this paper we remedy this by offering a number of hypotheses about the source of error. In so doing we aim to show that Cognitive Error Theory is a plausible competitor to Phenomenal Illusion Theory. (shrink)

In recent years, a disagreement has erupted between two camps of philosophers about the rationality of bias toward the near and bias toward the future. According to the traditional hybrid view, near bias is rationally impermissible, while future bias is either rationally permissible or obligatory. Time neutralists, meanwhile, argue that the hybrid view is untenable. They claim that those who reject near bias should reject both biases and embrace time neutrality. To date, experimental work has focused on future-directed near bias. (...) The primary aim of this paper is to shed light on the debate by investigating past-directed near bias. If people treat the past and future differently with respect to near bias, by being future-directed but not past-directed near biased, then this supports a particular version of the hybrid view: temporal metaphysic hybridism. If people treat the past and future the same with respect to near bias, then this supports a simple version of time neutralism, which explains both future bias and near bias in terms of the functioning of a single mechanism: the anticipatory/retrospectory mechanism. Our results undermine the claim that people are future-directed, but not past-directed, near biased, and hence do not support temporal metaphysic hybridism. They also fail to support simple time-neutralism; instead, they suggest that there are multiple mechanisms that differently shape future- and past-directed preferences. (shrink)

Gruber and Smith (2019) have conducted some interesting virtual reality (VR) experiments, but we think that these experiments fail to illuminate why people think that the present is special. Their experiments attempted to test a suggestion by Hartle (2005) that with VR one might construct scenarios in which people experience the same present twice. If that’s possible, then it could give us a reason to think that when we experience the present as being special, that’s not because it’s objectively so. (...) Instead, our experience of the present being special is a feature of having a psychology like ours. While we are sympathetic to the thought that there is no objective present, we do not think that these experiments give us a reason to think this. That said, VR experiments, such as Gruber and Smith’s, hold much promise for being able to illuminate various aspects of our temporal psychology.According to Hartle’s (2005) IGUS model (which is meant to resemble entities like us) sensory information is routed to two kinds of processes: conscious processes C, which cause behavior, and unconscious processes, U, which construct a schematic representation of the environment. Hartle proposed that we experience the present as being special because of the sensory information at a time entering into C. For Gruber et al. (2020), the succession of sensory information entering into C underpins our experience of time passing. Our experience of time passing is illusory because it fails to be verid... (shrink)

This paper presents a novel account of focal stress and pitch contour in English dialogue. We argue that one should analyse and treat focus and pitch contour jointly, since (i) some pragmatic interpretations vary with contour (e.g., whether an utterance accepts or rejects; or whether it implicates a positive or negative answer); and (ii) there are utterances with identical prosodic focus that in the same context are infelicitous with one contour, but felicitous with another. We offer an account of two (...) distinct pitch contours that predicts the correct felicity judgements and implicatures, outclassing other models in empirical coverage or formality. Prosodic focus triggers a presupposition, where what is presupposed and how the presupposition is resolved depends on prosodic contour. If resolving the presupposition entails the proffered content, then the proffered content is uninteresting and hence the utterance is in-felicitous. Otherwise, resolving the presupposition may lead to an implicature. We regiment this account in SDRT. (shrink)

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.

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

"It is difficult not to notice a curious unrest in the philosophic atmosphere of the time, a loosening of old landmarks, a softening of oppositions, a mutual borrowing from one another on the part of systems anciently closed, and an interest in new suggestions, however vague, as if the one thing sure were the inadequacy of extant school-solutions. The dissatisfactions with these seems due for the most part to a feeling that they are too abstract and academic. Life is confused (...) and superabundant, and what the younger generation appears to crave is more of the temperament of life in its philosophy, even though it were at some cost of logical rigor and formal purity." - William James (1904). -/- Abstract: The study of model-based reasoning (MBR) is one of the most interesting recent developments at the intersection of psychology and the philosophy of science. Although a broad and eclectic area of inquiry, one central axis by which MBR connects these disciplines is anchored at one end in theories of internal reasoning (in cognitive science), and at the other, in C.S. Peirce’s semiotics (in philosophy). In this paper, we attempt to show that Peirce’s semiotics actually has more natural affinity on the psychological side with ecological psychology, as originated by James J. Gibson and especially Egon Brunswik, than it does with non-interactionist approaches to cognitive science. In particular, we highlight the strong ties we believe to exist between the triarchic structure of semiotics as conceived by Peirce, and the similar triarchic stucture of Brunswik’s lens model of organismic achievement in irreducibly uncertain ecologies. The lens model, considered as a theory of creative abduction, provides a concrete instantiation of at least one, albeit limited, interpretation of Peirce’s semiotics, one that we believe could be quite fruitful in future theoretical and empirical investigations of MBR in both science an philosophy.

This chapter examines whether high prices for gene therapies are justified and whether the problems associated with high prices can be solved by the "pay for performance" (P4P) reimbursement model. To this end, we first describe how prices for new drugs, including gene therapies, are set in Germany (section 2.). P4P is then presented as an example of a reimbursement model (section 3.). The subsequent ethical analysis (section 4.) first examines whether P4P models can sustainably guarantee the right to health (...) and healthcare for all people (section 4.1; cf. on the "sustainable right to health" already Alex, 2021). It is then shown that cost-benefit analyses for setting prices for new gene therapies must be viewed critically from an ethical perspective and pose a problem for equity of access and thus also for the sustainable guarantee of a right to health (section 4.2). The final question is whether P4P is compatible with the idea of human dignity (Article 1 I 1 of the German Basic Law) (section 4.3; cf. already König et al., 2020). -/- Alex, K.

What happens when someone acts? A familiar answer goes like this. There is something that the agent wants, and there is an action that he believes conducive to its attainment. His desire for the end, and his belief in the action as a means, justify taking the action, and they jointly cause an intention to take it, which in turn causes the corresponding movements of the agent's body. I think that the standard story is flawed in several respects. The flaw (...) that will concern me in this paper is that the story fails to include an agent-or, more precisely, fails to cast the agent in his proper role. (shrink)

I argue that Kripke’s construal of the distinction between speaker’s reference and semantic reference, in ‘Speaker’s reference and semantic reference’ (Kripke in Midwest Stud Philos 2:255–276, 1977), in conjunction with an intuitive view of the nature of conventions, implies a theory of semantic reference that is distinct from his causal theory. On this theory, semantic reference is conventionalized speaker’s reference. The argument concerning Kripke has two general implications. First, any theory that features a notion of speaker’s reference will have great (...) difficulty in avoiding the view that semantic reference is conventionalized speaker’s reference. Second, theories that deny that there is a viable notion of speaker’s reference, and thereby deny that semantic reference is conventionalized speaker’s reference, will face an uphill battle in meeting certain general constraints originating in the theory of conventions.

The agent portrayed in much philosophy of action is, let's face it, a square. He does nothing intentionally unless he regards it or its consequences as desirable. The reason is that he acts intentionally only when he acts out of a desire for some anticipated outcome; and in desiring that outcome, he must regard it as having some value. All of his intentional actions are therefore directed at outcomes regarded sub specie boni: under the guise of the good. This agent (...) is conceived as being capable of intentional action—and hence as being an agent—only by virtue of being a pursuer of value. I want to question whether this conception of agency can be correct. Surely, so general a capacity as agency cannot entail so narrow a cast of mind. Our moral psychology has characterized, not the generic agent, but a particular species of agent, and a particularly bland species of agent, at that. It has characterized the earnest agent while ignoring those agents who are disaffected, refractory, silly, satanic, or punk. I hope for a moral psychology that has room for the whole motley crew. I shall begin by examining why some philosophers have thought that the attitudes motivating intentional actions involve judgments of value. I shall then argue that their conception of these attitudes is incorrect. Finally, I shall argue that practical reason should not be conceived as a faculty for pursuing value. (shrink)

A story does more than recount events; it recounts events in a way that renders them intelligible, thus conveying not just information but also understanding. We might therefore be tempted to describe narrative as a genre of explanation. When the police invite a suspect to “tell his story,” they are asking him to explain the blood on his shirt or his absence from home on the night of the murder; and whether he is judged to have a “good story” will (...) depend on its adequacy as an explanation. Can we account for the explanatory force of narrative with the models of explanation available in the philosophy of science? Or does narrative convey a different kind of understanding, which requires a different model and perhaps even a term other than ‘explanation’? (shrink)

Inscrutability arguments threaten to reduce interpretationist metasemantic theories to absurdity. Can we find some way to block the arguments? A highly influential proposal in this regard is David Lewis’ ‘ eligibility ’ response: some theories are better than others, not because they fit the data better, but because they are framed in terms of more natural properties. The purposes of this paper are to outline the nature of the eligibility proposal, making the case that it is not ad hoc, but (...) instead flows naturally from three independently motivated elements; and to show that severe limitations afflict the proposal. In conclusion, I pick out the element of the eligibility response that is responsible for the limitations: future work in this area should therefore concentrate on amending this aspect of the overall theory.

Worlds where things divide forever ("gunk" worlds) are apparently conceivable. The conceivability of such scenarios has been used as an argument against "nihilist" or "near-nihilist" answers to the special composition question. I argue that the mereological nihilist has the resources to explain away the illusion that gunk is possible.

The terms `endurance' and `perdurance' are commonly thought to denote distinct ways for an object to persist, but it is surprisingly hard to say what these are. The common approach, defining them in terms of temporal parts, is mistaken, because it does not lead to two coherent philosophical alternatives: endurance so understood becomes conceptually incoherent, while perdurance becomes not just true but a conceptual truth. Instead, we propose a different way to articulate the distinction, in terms of identity rather than (...) temporal parts: an object endures if its identity is determined at every moment at which it exists. We make precise what it means for the identity of an object to be determined at a moment. We also discuss what role the endurance / perdurance distinction, so understood, should play in the debates about time, material objects and personal identity. (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.

I outline and motivate a way of implementing a closest world theory of indicatives, appealing to Stalnaker's framework of open conversational possibilities. Stalnakerian conversational dynamics helps us resolve two outstanding puzzles for a such a theory of indicative conditionals. The first puzzle -- concerning so-called 'reverse Sobel sequences' -- can be resolved by conversation dynamics in a theoryneutral way: the explanation works as much for Lewisian counterfactuals as for the account of indicatives developed here. Resolving the second puzzle, by contrast, (...) relies on the interplay between the particular theory of indicative conditionals developed here and Stalnakerian dynamics. The upshot is an attractive resolution of the so-called "Gibbard phenomenon" for indicative conditionals. (shrink)

Some argue that theories of universals should incorporate structural universals, in order to allow for the metaphysical possibility of worlds of 'infinite descending complexity' ('onion worlds'). I argue that the possibility of such worlds does not establish the need for structural universals. So long as we admit the metaphysical possibility of emergent universals, there is an attractive alternative description of such cases.

I have therefore decided to venture out of the philosophical armchair in order to examine the empirical evidence, as gathered by psychologists aiming to prove or disprove motivational conjectures like mine. By and large, this evidence is indirect in relation to my account of agency, since it is drawn from cases in which the relevant motive has been forced into the open by the manipulations of an experimenter. The resulting evidence doesn’t tend to show the mechanism of agency humming along (...) in accordance with my specifications; it tends to show the knocks and shudders that such a mechanism emits when put under stress. But we often learn about the normal workings of things by subjecting them to abnormal conditions; and viewed in this light, various programs of psychological research offer indirect support to my account of agency. I’ll begin by reviewing the relevant research, leaving its relevance to my account of agency for the final section of the paper. (shrink)

How are permutation arguments for the inscrutability of reference to be formulated in the context of a Davidsonian truth-theoretic semantics? Davidson takes these arguments to establish that there are no grounds for favouring a reference scheme that assigns London to “Londres”, rather than one that assigns Sydney to that name. We shall see, however, that it is far from clear whether permutation arguments work when set out in the context of the kind of truth-theoretic semantics which Davidson favours. The principle (...) required to make the argument work allows us to resurrect Foster problems against the Davidsonian position. The Foster problems and the permutation inscrutability problems stand or fall together: they are one puzzle, not two. (shrink)

This paper discusses the uniqueness thesis, a core thesis in the epistemology of disagreement. After presenting uniqueness and clarifying relevant terms, a novel counterexample to the thesis will be introduced. This counterexample involves logical disagreement. Several objections to the counterexample are then considered, and it is argued that the best responses to the counterexample all undermine the initial motivation for uniqueness.

Michael J. Almeida presents a bold new defence of the existence of God. He argues that entrenched principles in philosophical theology which have served as basic assumptions in apriori, atheological arguments are in fact philosophical dogmas. Almeida argues that not only are such principles false - they are necessarily false.

Priority monism is the view that the cosmos is the only independent concrete object. The paper argues that, pace its proponents, Priority monism is in conflict with the dependence of any whole on any of its parts: if the cosmos does not depend on its parts, neither does any smaller composite.

Liberalism has a complicated and sometimes uneasy relationship with truth. On one hand, liberalism requires that truth be widely valued and widely shared. It demands that governments be truthful and that citizens have ready access to numerous truths. Some liberals even take facilitating the discovery and dissemination of truth to be part of the raison d’être of liberal institutions. On the other hand, liberalism is averse to proclaiming or enforcing truth. It detaches truth from political legitimacy and deems certain truths (...) unfit to serve as bases of government. Some liberals have even suggested that liberal theory must work “without the concept of truth.” How has liberalism come to both demand truth and eschew it? This introductory section provides the beginnings of an answer by surveying some of the origins and core elements of liberal thought. (shrink)

R.J. Barnes (chapter 3) takes up the ways in which Sicilian comedy engaged current intellectual fashions, especially philosophy. Sicily was the home of rich and influential poetic and philosophical traditions that Epicharmus held up for comic examination and ridicule.

The biological sciences have always proven a fertile ground for philosophical analysis, one from which has grown a rich tradition stemming from Aristotle and flowering with Darwin. And although contemporary philosophy is increasingly becoming conceptually entwined with the study of the empirical sciences with the data of the latter now being regularly utilised in the establishment and defence of the frameworks of the former, a practice especially prominent in the philosophy of physics, the development of that tradition hasn’t received the (...) wider attention it so thoroughly deserves. This review will briefly introduce some recent significant topics of debate within the philosophy of biology, focusing on those whose metaphysical themes (in everything from composition to causation) are likely to be of wide-reaching, cross-disciplinary interest.

This is an extended review of John Dupré's _Processes of Life_, a collection of essays. It clarifies Dupré's concepts of reductionism and anti-reductionism, and critically examines his associated discussions of downward causation, and both the context sensitivity and multiple realization of categories. It reviews his naturalistic monism, and critically distinguishes between his realism about categories and constructivism about classification. Challenges to his process ontology are presented, as are arguments for his pluralism about scientific categories. None of his main conclusions are (...) rejected; rather it is main arguments for them that are the focus. (shrink)

I argue that Anselmians ought to abandon traditional Anselmianism in favor of Moderate Anselmianism. Moderate Anselmianism advances the view that a being x = God iff for every essential property P of x, it is secondarily necessary that x has P, for most essential properties of x, it is not primarily necessary that x has P and the essential properties of x include omnipotence, omniscience, perfect goodness and necessary existence. Traditional Anselmians have no cogent response to most a priori atheological (...) arguments. But a priori atheological arguments present no serious problem for moderate Anselmians. Unlike traditional Anselmianism, Moderate Anselmianism explains why a priori atheological arguments can be convincing and nonetheless illusory. (shrink)

For Austin, Grice, and many others, undertaking a speech act like asserting or promising requires uttering something with a particular sense and reference in mind. We argue that the phenomenon of open-ended promises reveals this 'Locutionary Thesis' to be mistaken.

ABSTRACT: Recent work in moral theory includes an intriguing new argument that the vagueness of moral properties, together with two well-known and well-received metaethical principles, entails the incredible conclusion that it is impossible to be moral. I show that the argument equivocates between “it is true that A and B are morally indistinguishable” and “it is not false that A and B are morally indistinguishable.” As expected the argument is interesting but unsound. It is therefore not impossible to be moral.RÉSUMÉ: (...) Les travaux récents en théorie morale comprennent un nouvel argument intrigant voulant que le caractère vague des propriétés morales, joint à deux principes métaéthiques bien connus et généralement admis, entraîne une conclusion incroyable, soit qu’il est impossible d’être moral. Je montre que cet argument entretient l’équivoque entre «il est vrai que A et B sont moralement impossibles à distinguer» et «il n’est pas faux que A et B soient moralement impossibles à distinguer». Comme on s’y attendait, l’argument est intéressant mais mal fondé. Il n’est donc pas impossible d’être moral. (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.

The foundations of research ethics are riven with fault lines emanating from a fear that if research is too closely connected to weighty social purposes an imperative to advance the common good through research will justify abrogating the rights and welfare of study participants. The result is an impoverished conception of the nature of research, an incomplete focus on actors who bear important moral responsibilities, and a system of ethics and oversight highly attuned to the dangers of research but largely (...) silent about threats of ineffective, inefficient, and inequitable medical practices and health systems. -/- In For the Common Good: Philosophical Foundations of Research Ethics, Alex John London defends a conception of the common good that grounds a moral imperative with two requirements. The first is to promote research that generates the information necessary to enable key social institutions to effectively, efficiently, and equitably safeguard the basic interests of individuals. The second is to ensure that research is organized as a voluntary scheme of social cooperation that respects its various contributors' moral claims to be treated as free and equal. Connecting research to the goals of a just social order grounds a framework for assessing and managing research risk that reconciles these requirements and justifies key oversight practices in non-paternalistic terms. Reconceiving research ethics as resolving coordination problems and providing credible assurance that these requirements are being met expands the issues and actors that fall within the purview of the field and provides the foundation for a more unified and coherent approach to domestic and international research. -/- This is an open access title available under the terms of a CC BY-NC-ND 4.0 license.

Are women (simply) adult human females? Dictionaries suggest that they are. However, philosophers who have explicitly considered the question invariably answer no. This paper argues that they are wrong. The orthodox view is that the category *woman* is a social category, like the categories *widow* and *police officer*, although exactly what this social category consists in is a matter of considerable disagreement. In any event, orthodoxy has it that *woman* is definitely not a biological category, like the categories *amphibian* or (...) *adult human female*. -/- In the first part, a number of arguments are given for the view that women are adult human females; the second part turns to rebutting the main objections. Finally, a couple of morals are briefly noted: one for activist sloganeering, and one for ameliorative projects that seek to change the meaning of ‘woman’. (shrink)

Discussions of aesthetic reasons and normativity are becoming increasingly popular. This piece outlines six basic questions about aesthetic reasons, normativity, and value and discusses the space of possible answers to these questions. I divide the terrain into two groups of three questions each. First are questions about the shape of aesthetic reasons: what they favour, how strong they are, and where they come from. Second are relational questions about how aesthetic reasons fit into the wider normative landscape: whether they are (...) distinctive, what their normative status is, and how they interact with each other and with non-aesthetic reasons. This piece aims to provide a taxonomy to clarify and organise the burgeoning literature and to make a few concrete suggestions for avenues of future research. (shrink)

In this paper it is argued that we should amend the traditional understanding of the view known as the guise of the good. The guise of the good is traditionally understood as the view that we only want to act in ways that we believe to be good in some way. But it is argued that a more plausible view is that we only want to act in ways that we believe we have normative reason to act in. This change (...) – from formulating the view in terms of goodness to formulating it in terms of reasons – is significant because the revised view avoids various old and new counterexamples to the traditional view, because the revised view is better motivated than the traditional view, and because the revised view is better placed to explain certain features of desire than the traditional view. The paper finishes by showing that the conclusions reached are compatible with theories such as the buck passing account of value. (shrink)

In this paper, I argue that theories of perception that appeal to Helmholtz’s idea of unconscious inference (“Helmholtzian” theories) should be taken literally, i.e. that the inferences appealed to in such theories are inferences in the full sense of the term, as employed elsewhere in philosophy and in ordinary discourse. -/- In the course of the argument, I consider constraints on inference based on the idea that inference is a deliberate acton, and on the idea that inferences depend on the (...) syntactic structure of representations. I argue that inference is a personal-level but sometimes unconscious process that cannot in general be distinguished from association on the basis of the structures of the representations over which it’s defined. I also critique arguments against representationalist interpretations of Helmholtzian theories, and argue against the view that perceptual inference is encapsulated in a module. (shrink)

Recent work on rationality has been increasingly attentive to “coherence requirements”, with heated debates about both the content of such requirements and their normative status (e.g., whether there is necessarily reason to comply with them). Yet there is little to no work on the metanormative status of coherence requirements. Metaphysically: what is it for two or more mental states to be jointly incoherent, such that they are banned by a coherence requirement? In virtue of what are some putative requirements genuine (...) and others not? Epistemologically: how are we to know which of the requirements are genuine and which aren’t? This paper tries to offer an account that answers these questions. On my account, the incoherence of a set of attitudinal mental states is a matter of its being (partially) constitutive of the mental states in question that, for any agent that holds these attitudes jointly, the agent is disposed, when conditions of full transparency are met, to give up at least one of the attitudes.

This chapter is centered around an apparent tension that research on implicit bias raises between virtue and social knowledge. Research suggests that simply knowing what the prevalent stereotypes are leads individuals to act in prejudiced ways—biasing decisions about whom to trust and whom to ignore, whom to promote and whom to imprison—even if they reflectively reject those stereotypes. Because efforts to combat discrimination obviously depend on knowledge of stereotypes, a question arises about what to do next. This chapter argues that (...) the obstacle to virtue is not knowledge of stereotypes as such, but the “accessibility” of such knowledge to the agent who has it. “Accessibility” refers to how easily knowledge comes to mind. Social agents can acquire the requisite knowledge of stereotypes while resisting their pernicious influence, so long as that knowledge remains, in relevant contexts, relatively inaccessible. (shrink)

Research suggests that interventions involving extensive training or counterconditioning can reduce implicit prejudice and stereotyping, and even susceptibility to stereotype threat. This research is widely cited as providing an “existence proof” that certain entrenched social attitudes are capable of change, but is summarily dismissed—by philosophers, psychologists, and activists alike—as lacking direct, practical import for the broader struggle against prejudice, discrimination, and inequality. Criticisms of these “debiasing” procedures fall into three categories: concerns about empirical efficacy, about practical feasibility, and about the (...) failure to appreciate the underlying structural-institutional nature of discrimination. I reply to these criticisms of debiasing, and argue that a comprehensive strategy for combating prejudice and discrimination should include a central role for training our biases away. (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.
