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.

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)

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)

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.

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)

"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.

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

This 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.

Duncan Pritchard (2008, 2009, 2010, forthcoming) has argued for an elegant solution to what have been called the value problems for knowledge at the forefront of recent literature on epistemic value. As Pritchard sees it, these problems dissolve once it is recognized that that it is understanding-why, not knowledge, that bears the distinctive epistemic value often (mistakenly) attributed to knowledge. A key element of Pritchard’s revisionist argument is the claim that understanding-why always involves what he calls strong cognitive achievement—viz., cognitive (...) achievement that consists always in either (i) the overcoming of a significant obstacle or (ii) the exercise of a significant level of cognitive ability. After outlining Pritchard’s argument, we show (contra Pritchard) that understanding-why does not essentially involve strong cognitive achievement. Interestingly, in the cases in which understanding-why is distinctively valuable, it is (we argue) only because there is sufficiently rich objectual understanding in the background. If that’s right, then a plausible revisionist solution to the value problems must be sensitive to different kinds of understanding and what makes them valuable, respectively. (shrink)

Weisberg ([2009]) provides an argument that neither conditionalization nor Jeffrey conditionalization is capable of accommodating the holist’s claim that beliefs acquired directly from experience can suffer undercutting defeat. I diagnose this failure as stemming from the fact that neither conditionalization nor Jeffrey conditionalization give any advice about how to rationally respond to theory-dependent evidence, and I propose a novel updating procedure that does tell us how to respond to evidence like this. This holistic updating rule yields conditionalization as a special (...) case in which our evidence is entirely theory independent. 1 Introduction2 Conditionalization3 Holism and Conditionalization4 A Holistic Update5 HCondi and Dutch Books6 Commutativity and Learning about Background Theories6.1 Commutativity6.2 Learning about background theories7 In Summation.

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.

It has widely been assumed, by philosophers, that our first-person preferences regarding pleasurable and painful experiences exhibit a bias toward the future (positive and negative hedonic future-bias), and that our preferences regarding non-hedonic events (both positive and negative) exhibit no such bias (non-hedonic time-neutrality). Further, it has been assumed that our third-person preferences are always time-neutral. Some have attempted to use these (presumed) differential patterns of future-bias—different across kinds of events and perspectives—to argue for the irrationality of hedonic future-bias. This (...) paper experimentally tests these descriptive hypotheses. While as predicted we found first-person hedonic future-bias, we did not find that participants were time-neutral in all other conditions. Hence, the presumed asymmetry of hedonic/non-hedonic and first/third-person preferences cannot be used to argue for the irrationality of future-bias, since no such asymmetries exist. Instead, we develop a more fine-grained approach, according to which three factors—positive/negative valence, first/third-person, and hedonic/non-hedonic—each independently influence, but do not determine, whether an event is treated in a future-biased or time-neutral way.

Norman Daniels’s theory of health justice is the most comprehensive and systematic such theory we have. In one of the few articles published so far on Daniels’s new book, Just Health, Benjamin Sachs argues that Daniels’s core “principle of equality of opportunity does not do the work Daniels needs it to do.” Yet Sachs’s objections to Daniels’s framework are deeply flawed. Where these arguments do not rely on significant misreadings of Daniels, they ignore sensible strands in Just Health that considerably (...) dull their force. After disarming Sachs’s arguments against Daniels’s theory, I explain why I agree with Sachs’s conclusion: Daniels’s equality of opportunity-based account of health justice rests on shaky foundations.

Existing accounts of shared intention (by Bratman, Searle, and others) do not claim that a single token of intention can be jointly framed and executed by multiple agents; rather, they claim that multiple agents can frame distinct, individual intentions in such a way as to qualify as jointly intending something. In this respect, the existing accounts do not show that intentions can be shared in any literal sense. This article argues that, in failing to show how intentions can be literally (...) shared, these accounts fail to resolve what seems problematic in the notion of shared intention. It then offers an account in which the problem of shared intention is resolved, because intention can indeed be literally shared. This account is derived from Margaret Gilbert’s notion of a “pool of wills,” to which it applies Searle’s definition of intention. (shrink)

Reductive intellectualists hold that knowledge-how is a kind of knowledge-that. For this thesis to hold water, it is obviously important that knowledge-how and knowledge-that have the same epistemic properties. In particular, knowledge-how ought to be compatible with epistemic luck to the same extent as knowledge-that. It is argued, contra reductive intellectualism, that knowledge-how is compatible with a species of epistemic luck which is not compatible with knowledge-that, and thus it is claimed that knowledge-how and knowledge-that come apart.

We present an inferentialist account of the epistemic modal operator might. Our starting point is the bilateralist programme. A bilateralist explains the operator not in terms of the speech act of rejection ; we explain the operator might in terms of weak assertion, a speech act whose existence we argue for on the basis of linguistic evidence. We show that our account of might provides a solution to certain well-known puzzles about the semantics of modal vocabulary whilst retaining classical logic. (...) This demonstrates that an inferentialist approach to meaning can be successfully extended beyond the core logical constants. (shrink)

How should we undertand the role of norms—especially epistemic norms—governing assertive speech acts? Mitchell Green (2009) has argued that these norms play the role of handicaps in the technical sense from the animal signals literature. As handicaps, they then play a large role in explaining the reliability—and so the stability (the continued prevalence)—of assertive speech acts. But though norms of assertion conceived of as social norms do indeed play this stabilizing role, these norms are best understood as deterrents and not (...) as handicaps. This paper explains the stability problem for the maintenance of animal signals, and so human communication, for we are animals too, after all; the mechanics of the handicap principle; the role of deterrents and punishments as an alternative mechanism; and the role of social norms governing assertion for the case of human communication.

One challenge to the rationality of religious commitment has it that faith is unreasonable because it involves believing on insufficient evidence. However, this challenge and influential attempts to reply depend on assumptions about what it is to have faith that are open to question. I distinguish between three conceptions of faith each of which can claim some plausible grounding in the Judaeo-Christian tradition. Questions about the rationality or justification of religious commitment and the extent of compatibility with doubt look different (...) on accounts of faith in which trust or hope, rather than belief, are the primary basis for the commitments. On such accounts, while the person of faith has a stake in the truth of the content, practical as well as epistemic considerations can legitimately figure in normative appraisals. Trust and hope can be appropriate in situations of recognized risk, need not involve self-deception, and are compatible with the idea that one's purely epistemic opinions should be responsive only to evidence.Send article to KindleTo send this article to your Kindle, first ensure [email protected] is added to your Approved Personal Document E-mail List under your Personal Document Settings on the Manage Your Content and Devices page of your Amazon account.

A handful of well-known arguments (the 'diachronic Dutch book arguments') rely upon theorems establishing that, in certain circumstances, you are immune from sure monetary loss (you are not 'diachronically Dutch bookable') if and only if you adopt the strategy of conditionalizing (or Jeffrey conditionalizing) on whatever evidence you happen to receive. These theorems require non-trivial assumptions about which evidence you might acquire---in the case of conditionalization, the assumption is that, if you might learn that e, then it is not the (...) case that you might learn something else that is consistent with e. These assumptions may not be relaxed. When they are, not only will non-(Jeffrey) conditionalizers be immune from diachronic Dutch bookability, but (Jeffrey) conditionalizers will themselves be diachronically Dutch bookable. I argue: 1) that there are epistemic situations in which these assumptions are violated; 2) that this reveals a conflict between the premise that susceptibility to sure monetary loss is irrational, on the one hand, and the view that rational belief revision is a function of your prior beliefs and the acquired evidence alone, on the other; and 3) that this inconsistency demonstrates that diachronic Dutch book arguments for (Jeffrey) conditionalization are invalid.

We investigate claims about the frequency of "know" made by philosophers. Our investigation has several overlapping aims. First, we aim to show what is required to confirm or disconfirm philosophers’ claims about the comparative frequency of different uses of philosophically interesting expressions. Second, we aim to show how using linguistic corpora as tools for investigating meaning is a productive methodology, in the sense that it yields discoveries about the use of language that philosophers would have overlooked if they remained in (...) their "armchairs of an afternoon", to use J.L. Austin’s phrase. Third, we discuss facts about the meaning of "know" that so far have been ignored in philosophy, with the aim of reorienting discussions of the relevance of ordinary language for philosophical theorizing.

In this paper I argue that given the present state of relevant inquiry, the facts of religious diversity justify religious skepticism. Because of the diversity of religious claims, the denial of any detailed religious proposition is equivalent to a large disjunction of alternative claims. The same is true of the denial of metaphysical naturalism. And having typically acquired no detailed understanding of the whole panoply of religious views, religious believers and metaphysical naturalists are rarely in a position to judge, of (...) any such disjunction, how likely it is to be true. Now the investigative deficit here might conceivably be oversome, but the paper concludes by showing that even where it is overcome, we remain in conditions supporting religious skepticism because of the evolutionary immaturity of our species, which prevents us from being in a position to judge whether religious diversity as humans in the future – or some future species – will know it includes ideas about the Divine trumping any contrary ideas of today.

The concept of moral wrongness, many think, has a distinctive kind of referential stability, brought out by moral twin earth cases. This article offers a new account of the source of this stability, deriving it from a metaphysics of content: “substantive” radical interpretation, and first-order normative assumptions. This story is distinguished from extant “reference magnetic” explanations of the phenomenon, and objections and replies are considered.

Controversial view agnosticism is the thesis that we are rationally obligated to withhold judgment about a large portion of our beliefs in controversial subject areas, such as philosophy, religion, morality and politics. Given that one’s social identity is in no small part a function of one’s positive commitments in controversial areas, CVA has unsurprisingly been regarded as objectionably ‘spineless.’ That said, CVA seems like an unavoidable consequence of a prominent view in the epistemology of disagreement—conformism—according to which the rational response (...) to discovering that someone you identify as an epistemic peer or expert about p disagrees with you vis-à-vis p is to withhold judgment. This paper proposes a novel way to maintain the core conciliatory insight without devolving into an agnosticism that is objectionably spineless. The approach offered takes as a starting point the observation that–for reasons that will be made clear—the contemporary debate has bypassed the issue of the reasonableness of maintaining, rather than giving up, representational states weaker than belief in controversial areas. The new position developed and defended here explores this overlooked space; what results is a kind of controversial view. (shrink)

Several areas of welfare economics seek to evaluate states of affairs as a function of interpersonally comparable individual utilities. The aim is to map each state of affairs onto a vector of individual utilities, and then to produce an ordering of these vectors that can be represented by a mathematical function assigning a real number to each. When this approach is used in intertemporal contexts, a central theoretical question concerns the evaluative weight to be applied to utility coming at different (...) times. This question concerns the rate of pure time preference, which is one key determinant of the social discount rate. This article argues that the standard philosophical account of pure time preference is mistaken, because it ascribes to economists a methodological commitment they need not, and often do not, accept. This in turn undercuts the most common philosophical objection to pure time preference, which traces at least to Rawls’s A Theory of Justice. The article then evaluates three further objections to pure time preference, concluding that it might still be defensible under certain circumstances. The article closes by articulating a final argument that is suggested by the “Social, Economic and Ethical Concepts and Methods” chapter of the most recent Intergovernmental Panel on Climate Change report. If this further argument is sound, it would constitute a decisive objection to pure time preference as it currently figures in much intertemporal welfare economics. (shrink)

It is standardly assumed that there are three — and only three — ways to solve problem of temporary intrinsics: (a) embrace presentism, (b) relativize property possession to times, or (c) accept the doctrine of temporal parts. The first two solutions are favoured by endurantists, whereas the third is the perdurantist solution of choice. In this paper, I argue that there is a further type of solution available to endurantists, one that not only avoids the usual costs, but is structurally (...) identical to the temporal-parts solution preferred by perdurantists. In addition to providing a general characterization of this new type of solution, I discuss certain of its anticipations in the literature on bundle theory, as well as provide a detailed development of it in terms of my own preferred metaphysics of ordinary objects — namely, a distinctive form of substratum theory tracing to Aristotle.

If individual knowledge and justification can be vanquished by epistemic defeaters, then the same should go for group knowledge. Lackey (2014) has recently argued that one especially strong conception of group knowledge defended by Bird (2010) is incapable of preserving how it is that (group) knowledge is ever subject to ordinary mechanisms of epistemic defeat. Lackey takes it that her objections do not also apply to a more moderate articulation of group knowledge--one that is embraced widely in collective epistemology--and which (...) she does not challenge. This paper argues that given certain background premises that are embraced by orthodox thinking in collectivist epistemology, the more moderate account of group knowledge cannot make sense of either psychological or normative epistemic defeaters. I conclude by offering some suggestions for how the more moderate proposal might avoid this result. (shrink)

Sometimes it is indeterminate what an agent morally ought do. This generates a Decision Ought Challenge—to give moral guidance to agents in such a scenario. This article is a field guide to the options for a theory of the decision ought for cases of indeterminacy. Three categories of view are evaluated, and the best representative for each is identified.

The purpose of this paper is to challenge what is often called the “Uniqueness” thesis. According to this thesis, given one’s total evidence, there is a unique rational doxastic attitude that one can take to any proposition. It is sensible for defenders of Uniqueness to commit to an accompanying principle that: when some agent A has equal epistemic reason both to believe that p and to believe that not p, the unique epistemically rational doxastic attitude for A to adopt with (...) respect to whether p is the suspension of judgment. In this paper, I offer a case wherein the agent has equal epistemic reason both to believe that p and to believe that not p, but the agent is not epistemically required to suspend judgment about whether p. Furthermore, the case is such that there seems to be no uniquely rational attitude for the agent to adopt. (shrink)

A common epistemological assumption in contemporary bioethics held b y both proponents and critics of non-traditional forms of cognitive enhancement is that cognitive enhancement aims at the facilitation of the accumulation of human knowledge. This paper does three central things. First, drawing from recent work in epistemology, a rival account of cognitive enhancement, framed in terms of the notion of cognitive achievement rather than knowledge, is proposed. Second, we outline and respond to an axiological objection to our proposal that draws (...) from recent work by Leon Kass (2004), Michael Sandel (2009), and John Harris (2011) to the effect that ‘enhanced’ cognitive achievements are (by effectively removing obstacles to success) not worthy of pursuit, or are otherwise ‘trivial’. Third, we show how the cognitive achievement account of cognitive enhancement proposed here fits snugly with recent active externalist approaches (e.g., extended cognition) in the philosophy of mind and cognitive science.

In The Construction of Social Reality, John Searle develops a theory of institutional facts and objects, of which money, borders and property are presented as prime examples. These objects are the result of us collectively intending certain natural objects to have a certain status, i.e. to ‘count as’ being certain social objects. This view renders such objects irreducible to natural objects. In this paper we propose a radically different approach that is more compatible with standard economic theory. We claim that (...) such institutional objects can be fully understood in terms of actions and incentives, and hence the Searlean apparatus solves a non-existent problem. (shrink)

Forty years’ experience as a bacterial geneticist has taught me that bacteria possess many cognitive, computational and evolutionary capabilities unimaginable in the first six decades of the twentieth century. Analysis of cellular processes such as metabolism, regulation of protein synthesis, and DNA repair established that bacteria continually monitor their external and internal environments and compute functional outputs based on information provided by their sensory apparatus. Studies of genetic recombination, lysogeny, antibiotic resistance and my own work on transposable elements revealed multiple (...) widespread bacterial systems for mobilizing and engineering DNA molecules. Examination of colony development and organization led me to appreciate how extensive multicellular collaboration is among the majority of bacterial species. Contemporary research in many laboratories on cell–cell signaling, symbiosis and pathogenesis show that bacteria utilise sophisticated mechanisms for intercellular communication and even have the ability to commandeer the basic cell biology of ‘higher’ plants and animals to meet their own needs. This remarkable series of observations requires us to revise basic ideas about biological information processing and recognise that even the smallest cells are sentient beings. (shrink)

Recently, mainstream philosophy journals have tended to implement more and more stringent forms of peer review, probably in an attempt to prevent editorial decisions that are based on factors other than quality. Against this trend, we propose that journals should relax their standards of acceptance, as well as be less restrictive about whom is to decide what is admitted into the debate. We start by arguing, partly on the basis of the history of peer review in the journal Mind, that (...) past and current peer review practices attest to partisanship with respect to philosophical approach. Then, we explain that such partisanship conflicts with the standard aims of peer review, and that it is both epistemically and morally problematic. This assessment suggests that, if feasible, journals should treat all available and proposed standards of acceptance in philosophy as epistemically equal, and that philosophical work should be evaluated in terms of the novelty and significance of its contribution to developing thought in ways that are of value. Finally, we show, in a programmatic way, that improving the current situation is feasible, and can be done fairly easily. (shrink)

In a series of works Sosa (in: Knowledge in perspective, Cambridge University Press, Cambridge, 1991; A virtue epistemology: apt belief and reflective knowledge, Oxford University Press, Oxford, 2007; Reflective knowledge: apt belief and reflective knowledge, Oxford University Press, Oxford, 2009; ‘How Competence Matters in Epistemology’, Philos Perspect 24(1):465–475, 2010; Knowing full well, Princeton University Press, Princeton, 2011; Judgment and agency, Oxford University Press, Oxford, 2015; Epistemology, Princeton University Press, Princeton, 2017) has defended the view that there are two kinds or (...) ‘grades’ of knowledge, animal and reflective. One of the most persistent critics of Sosa’s attempts to bifurcate knowledge is Kornblith (in: Greco (ed) Ernest sosa and his critics, Wiley, Hoboken, 2004; ‘Sosa in Perspective’, Philos Stud 144(1):127–136, 2009; On reflection, Oxford University Press, Oxford, 2012). Our aim in this paper is to outline and evaluate Kornblith’s criticisms. We will argue that, while they raise a range of difficult (exegetical and substantive) questions about Sosa’s ‘bi-level’ epistemology, Sosa has the resources to adequately respond to all of them. Thus, this paper is a (qualified) defence of Sosa’s bi-level epistemology. (shrink)

Many accounts of structural rationality give a special role to logic. This paper reviews the problem case of clear-eyed logical uncertainty. An account of rational norms on belief that does not give a special role to logic is developed: doxastic probabilism.

I offer an account of how ideals motivate us. My account suggests that although emulating an ideal is often rational, it can lead us to do irrational things. * This is the third in a series of four papers on narrative self-conceptions and their role in moral motivation. In the first paper, “The Self as Narrator” (to appear in Autonomy and the Challenges to Liberalism: New Essays, ed. Joel Anderson and John Christman), I explore the motivational role of narrative self-conceptions, (...) drawing on Daniel Dennett’s notion of the self as a “center of narrative gravity”. In the second paper, “Willing the Law” (in Practical Conflicts, ed. Monika Betzler and Peter Baumann [Cambridge: Cambridge University Press, forthcoming]), I explore the role of selfconceptions in Kantian “conflicts in the will”, drawing on Christine Korsgaard’s notion of “practical identities”. In a fourth paper, “A Sense of Self” (ms), I explore the role of narrative self-con-ceptions in Kantian “conflicts in conception”, drawing on the work of Thomas Nagel and John Perry on the self.

Consider two epistemic experts—for concreteness, let them be two weather forecasters. Suppose that you aren’t certain that they will issue identical forecasts, and you would like to proportion your degrees of belief to theirs in the following way: first, conditional on either’s forecast of rain being x, you’d like your own degree of belief in rain to be x. Secondly, conditional on them issuing different forecasts of rain, you’d like your own degree of belief in rain to be some weighted (...) average of the forecast of each. Finally, you’d like your degrees of belief to be given by an orthodox probability measure. Moderate ambitions, all. But you can’t always get what you want. (shrink)

I critically analyze Kevin Elliott’s A Tapestry of Values in order to tease out his views on the nature and status of values or value judgments in the text. I show there is a tension in Elliott’s view that is closely connected to a major lacuna in the philosophical literature on values in science: the need for a better theory of values.

The two purposes of this essay. The general philosophical problem with most versions of social libertarianism and how this essay will proceed. The specific problem with liberty explained by a thought-experiment. The positive and abstract theory of interpersonal liberty-in-itself as ‘the absence of interpersonal initiated constraints on want-satisfaction’, for short ‘no initiated impositions’. The individualistic liberty-maximisation theory solves the problems of clashes, defences, and rectifications without entailing interpersonal utility comparisons or libertarian consequentialism. The practical implications of instantiating liberty: three rules (...) of liberty-in-practice, 1) initial ultimate control of one’s body, 2) initial ultimate control of one’s used resources, 3) consensual interpersonal interactions and resource transfers. These rules are economically efficient and maximise general want-satisfaction. Private property and legal remedies are additional practical institutional aspects, but to which ‘initiated impositions’ then apply prima facie. Libertarian law is often mistaken for complete libertarianism. Moral explanations are a separate issue. The three main moral theories imply libertarianism, but it can be morally posited independently of them. Critical rationalism and its application. No empirical or argumentative support for theories. An important ambiguity with ‘justification’. How the epistemology applies to the theory of liberty and its application but remains separable in principle. Conclusion: there are further published explanations but this should be enough to generate useful criticism. Appendix replying to some typical comments. (shrink)

Supervaluationism is often described as the most popular semantic treatment of indeterminacy. There’s little consensus, however, about how to fill out the bare-bones idea to include a characterization of logical consequence. The paper explores one methodology for choosing between the logics: pick a logic thatnorms beliefas classical consequence is standardly thought to do. The main focus of the paper considers a variant of standard supervaluational, on which we can characterizedegrees of determinacy. It applies the methodology above to focus ondegree logic. (...) This is developed first in a basic, single-premise case; and then extended to the multipremise case, and to allowdegreesof consequence. The metatheoretic properties of degree logic are set out. On the positive side, the logic is supraclassical—all classical valid sequents are degree logic valid. Strikingly, metarules such as cut and conjunction introduction fail. (shrink)

What does being money consist in? We argue that something is money if, and only if, it is typically acquired in order to realise the reduction in transaction costs that accrues in virtue of agents coordinating on acquiring the same thing when deciding what thing to acquire in order to exchange. What kinds of things can be money? We argue against the common view that a variety of things (notes, coins, gold, cigarettes, etc.) can be money. All monetary systems are (...) best interpreted as implementing the same basic protocol. Money, i.e. the thing that we coordinate on acquiring in order to lower our transaction costs, is, in all cases, a set of positions on an abstract mathematical object, namely a relative ratio scale. The things that we ordinarily call ‘money’ are merely records of positions on such a scale. (shrink)
