Thanks to the work of Stephen Newmyer, Plutarch’s importance for modern philosophical debates concerning animal rationality and rights has been brought to the forefront. But Newmyer’s important scholarship overlooks Plutarch’s commitment to a range of rational functions that can be ascribed to animals of various sorts throughout the Moralia. Through an application of the ‘spectrum of animal rationality’ described in the treatise On Moral Virtue to the dialogues where his interlocutors explore the rational capacities of non-human animals (especially Whether (...) Land or Sea Animals are Smarter and Gryllus), this article argues that Plutarch’s commitment to a broad and inclusive sense of ‘reason’ conditions any positive account of animal rationality. Rather, any suggestions of the rational capacities of non-human animals are deeply implicated in Plutarch’s universal system of reason, which differentiates grades of rationality to animals based on natural difference – not unlike his contemporary Stoics. While modern proponents of animal rationality might find some of Plutarch’s ideas unpalatable, the upshot of this study is a fuller sense of Plutarch’s articulate and inclusive sense of reason, which is able to accommodate not only Platonist and Peripatetic notions, but also those of the Stoics and Epicureans, who are especially singled out in the humorous dialogue Gryllus. Thus, Plutarch’s ‘eclecticism’ can be explained as a deep commitment to a universal notion of ‘reason’, marked by a range of functions accessible to all animals – including his philosophical enemies.

FISIOLOGIA DA REPRODUÇÃO BOVINA -/- 3 – GESTAÇÃO -/- -/- INTRODUÇÃO -/- -/- O estabelecimento da gestação é o objetivo fundamental dos programas reprodutivos. Após a fertilização, o zigoto se divide e dá origem a embriões de duas, quatro, oito, dezesseis células, e no sétimo dia o embrião tem mais de 80 células. Entre os dias 16 e 18 do ciclo estral, o embrião se alonga e atinge 15 cm de comprimento. O estabelecimento da gestação depende da supressão da secreção (...) de PGF2α pelo embrião, que é realizada por meio da secreção de interferon-τ. Em vacas leiteiras, uma alta proporção de embriões morre antes do reconhecimento materno da gravidez. -/- Para evitar perdas embrionárias, é importante conhecer a fisiologia da gestação. Este capítulo descreve os principais processos fisiológicos que levam ao estabelecimento e manutenção da gestação e ao manejo da vaca prenhe. -/- -/- 3.1 Transporte de gametas -/- -/- Os gametas, óvulo e esperma, são definidos como células germinativas maduras que possuem um número haploide (n = 23) de cromossomos que, quando unidos, dão origem a um novo indivíduo geneticamente diferente de ambos os pais. -/- -/- 3.1.1 Transporte dos espermatozoides -/- -/- Os espermatozoides obtidos diretamente do testículo são funcionalmente imaturos, incapazes de fertilizar o óvulo. Durante sua permanência no epidídimo, os espermatozoides sofrem alterações na morfologia, mobilidade e metabolismo, o que lhes dá a capacidade de fertilização. No entanto, eles terão que passar algum tempo no trato genital feminino para que adquiram o estado ideal para fertilizar; processo conhecido como capacitação. -/- Durante a monta natural, a ejaculação ocorre na vagina e são depositados cerca de 5 x 109 de espermatozoides (volume ejaculado de três a cinco ml e concentração espermática de 1 x 109 a 1,2 x 109 por ml) suspensos no plasma seminal, este é basicamente constituído pelas secreções das vesículas seminais e da próstata. Após a ejaculação, o transporte dos espermatozoides é favorecido pelas contrações uterinas e vaginais que ocorrem durante e após a relação sexual. Nos primeiros minutos após a cópula, os espermatozoides já podem ser encontrados no oviduto, o que se deve às contrações do trato genital. Durante o transporte dos espermatozoides, a mobilidade individual é importante, já que apenas os espermatozoides com essa capacidade chegam ao local da fertilização. -/- O primeiro local para o estabelecimento de uma população de espermatozoides é a cérvix do útero, principalmente nas criptas, onde permanecem protegidos da fagocitose. É importante observar que apenas os espermatozoides móveis permanecem nas criptas; aqueles que estão mortos ou sem movimento são eliminados pelos fagócitos ou pelo movimento do muco cervical em direção a vagina. Embora uma população temporária de espermatozoides seja estabelecida no colo do útero, o reservatório funcional de espermatozoides está localizado na região distal do istmo. -/- As características do muco cervical são importantes para o transporte dos espermatozoides; assim, durante o estro e a ovulação, o muco fica mais aquoso, o que favorece a migração dos espermatozoides, enquanto na fase lútea o muco torna-se mais viscoso, dificultando sua movimentação. -/- Já no útero, o transporte de espermatozoides depende principalmente das contrações uterinas. Aqui, os espermatozoides ficam suspensos nas secreções uterinas, cuja função é promover sua viabilidade e transporte. As secreções uterinas contêm fagócitos que removem os espermatozoides mortos e imóveis, embora os espermatozoides normais também sejam removidos por esse meio. Algumas substâncias, como prostaglandinas e ocitocina, promovem o transporte. -/- O oviduto desempenha um papel muito importante no transporte e maturação dos gametas, bem como na fertilização e desenvolvimento embrionário inicial. As características das secreções do oviduto variam de acordo com a região do oviduto e o estágio do ciclo estral. Uma vez que os espermatozoides atingem o oviduto, eles são distribuídos em dois lugares. Alguns espermatozoides são imediatamente transportados para a região da ampola; esses são os primeiros que encontram o ovócito, mas sua capacidade de fertilização é limitada. O outro local de distribuição é a região caudal do istmo; aqui eles permanecem até que a ovulação seja iminente. Para que a fertilização ocorra, é necessário que o espermatozoide se estabeleça neste local por um período de seis a oito horas, antes da ovulação. Uma a duas horas, antes da ovulação, um movimento ativo do espermatozoide é observado em direção à região da ampola. -/- No oviduto, o transporte de espermatozoides depende de seu movimento, do fluido ovidutal e das contrações musculares. É comum que alguns espermatozoides continuem seu movimento e saiam pela fímbria. A viabilidade do espermatozoide de uma ejaculação varia de 24 a 48 horas. -/- -/- 3.1.2 Transporte do ovócito -/- -/- A ovulação é o processo pelo qual o ovócito é liberado. Este evento é desencadeado pela secreção de LH conhecida como pico de LH ovulatório ou pré-ovulatório. -/- Devido ao efeito de LH o cúmulos descola-se da parede folicular e começa a observar-se um adelgaçamento em uma pequena área da parede folicular, causada pela isquemia e pela ação de enzimas proteolíticas. Mais tarde, nesta área, uma pequena vesícula protuberante (estigma) se forma e eventualmente se quebra. Depois que o estigma é quebrado, o cúmulos que contém o ovócito junto com as células da granulosa. O ovócito é capturado pela fimbria; processo apoiado por movimentos dos cílios da mucosa e por contrações das pregas desta estrutura. Assim que o oócito é capturado, ele é transportado para a ampola. -/- 3.8 Manejo da vaca seca -/- -/- Em programas de manejo anteriores, a vaca seca recebia comida de pior qualidade e permanecia no esquecimento até o parto ocorrer. No entanto, os resultados dos estudos mostram que o período de seca é decisivo para que a vaca atinja um nível ótimo de produção e tenha um bom desempenho reprodutivo pós-parto. Por outro lado, o manejo correto no período seco reduz a incidência de doenças metabólicas no puerpério. O objetivo do período de seca é oferecer um descanso à vaca antes do parto, durante o qual o tecido mamário se regenera, o feto atinge seu crescimento máximo e a vaca atinge uma condição corporal adequada para enfrentar uma nova lactação. A duração recomendada do período de seca é de seis a oito semanas (60 dias). A involução do tecido da glândula mamária leva de duas a três semanas e um período semelhante é necessário para reiniciar a síntese do leite antes do parto. Assim, um período de seca de 60 dias é suficiente; entretanto, a duração desse período é questionada e tempos mais curtos foram propostos. Provavelmente, nos próximos anos, mais informações estarão disponíveis para apoiar a redução do período de seca. -/- Em termos de produção, o objetivo do manejo durante o período de seca é levar a vaca ao pico de lactação cinco a seis semanas após o parto, com produção máxima de leite. Estima-se que para cada kg de leite que aumenta no pico da lactação, ocorre um aumento de 120 kg ao longo da lactação. Para atingir este objetivo é necessário que a vaca tenha um consumo adequado de matéria seca após o parto; porém, três semanas antes do parto, a vaca reduz seu consumo em até 30%, para o qual é necessário estabelecer um manejo eficaz para promover um alto consumo de matéria seca durante a parte final do período de seca e durante as três primeiras semanas pós-parto (período de transição: três semanas antes e três após o parto). -/- A falta de capacidade de consumir as necessidades de matéria seca após o parto obriga a vaca a mobilizar suas reservas de gordura. Praticamente todas as vacas após o parto mobilizam suas reservas de gordura e perdem a condição corporal. A mobilização da gordura corporal causa degeneração gordurosa do fígado e é responsável por distúrbios metabólicos e retardo da atividade ovariana pós-parto. O grau de degeneração da gordura está relacionado à magnitude da mobilização da gordura corporal, que é diretamente dependente da capacidade de consumir matéria seca. Dessa forma, vacas com alto consumo de matéria seca no pós-parto, mobilizam menos gordura e, portanto, o dano ao fígado é menor. -/- O período de secagem é dividido em duas partes, a primeira compreende desde a secagem até duas semanas antes do parto; a segunda parte inclui as últimas duas semanas de gestação e é conhecida como período de desafio. -/- O período de desafio é decisivo para o desempenho produtivo e reprodutivo. Durante este período, uma dieta semelhante em ingredientes e forma deve ser oferecida à dieta que farão após o parto. Para facilitar esse manejo, as vacas deste grupo devem ser separadas do restante das vacas secas. -/- No período de seca, atenção especial deve ser dada para que as vacas não alcancem escores de condição corporal de quatro ou mais, uma vez que o excesso de gordura causa problemas metabólicos durante o puerpério, que afetam negativamente o comprometimento uterino e início da atividade ovariana pós-parto (figura 8). -/- -/- -/- Figura 8: Estágios fisiológicos e reprodutivos da vaca leiteira. Período de espera voluntário (PVE). -/- -/- 3.9 O período de transição -/- -/- O período de transição na vaca leiteira é três semanas antes e três após o parto (também conhecido como periparto). Nos últimos anos, esse tema tem merecido muitas pesquisas, pois o que for bem ou mal feito durante ele terá impacto na eficiência reprodutiva e na produção de leite. Durante o período de transição, a glândula mamária se prepara para a lactogênese, o feto cresce exponencialmente, a resposta imune é suprimida e o consumo de matéria seca diminui; além disso, o rúmen deve se adaptar à dieta recebida pelas vacas in natura (primeiras três semanas pós-parto), dieta caracterizada por alto teor de energia na forma de grãos. -/- Muitos distúrbios que se manifestam nas duas primeiras semanas pós-parto (hipocalcemia clínica e subclínica, cetose, retenção placentária, prolapso uterino, metrite, mastite, deslocamento do abomaso etc.), como os que se apresentam posteriormente (laminite, cistos ovarianos , endometrite e anestro) têm sua origem nos erros cometidos durante o período de transição. Em grande parte, os problemas estão relacionados à diminuição do consumo de matéria seca durante o período de transição; assim, o consumo diminui cerca de 30% durante as últimas três semanas de gestação, mas a maior parte da redução ocorre cinco a sete dias antes do parto. O manejo correto do período de transição tem como objetivo manter a normocalcemia, fortalecer o sistema imunológico, adaptar o rúmen a uma dieta rica em energia e aumentar a ingestão de matéria seca. Algumas recomendações gerais de manejo durante o período de transição são: separar as novilhas das vacas, ter comedouro suficiente para todos os animais, ter as mesmas características dos comedouros de vacas frescas e a dieta deve estar disponível 24 horas por dia (figuras 9 e 10). -/- -/- -/- Figura 10: O desempenho produtivo e reprodutivo das vacas depende em grande parte da condição corporal no momento do parto. Nesta fotografia são mostradas vacas recém-paridas, com uma condição corporal ideal (3,5). -/- Figura 9: Vacas no curral do desafio. Recomenda-se separar as novilhas das vacas, ter espaço suficiente com comedouro e a dieta deve estar disponível 24 horas por dia. -/- -/- RESUMO -/- -/- Cerca de 5 bilhões de espermatozoides são depositados em a genitália da vaca durante a cópula. Os espermatozoides devem permanecer no istmo e na região da junção útero-tubária por seis a oito horas antes da ovulação para obter uma alta taxa de fertilização. A viabilidade dos espermatozoides no útero é de 24 a 48 horas. A polispermia é efetivamente bloqueada nas primeiras 10 horas após a ovulação. Os blastômeros de embriões de duas, quatro e oito células são pluripotentes. A eclosão do embrião ocorre no oitavo dia. O tempo que o embrião leva para chegar ao útero é de três a quatro dias. Entre os dias 16 e 18 do ciclo, o embrião produz interferon-t, para bloquear a secreção de PGF2α. Entre os dias 17 e 18, o embrião se fixa ao endométrio. A medição da progesterona entre os dias 20-24 pós-infecção é 100% precisa na identificação de vacas não gestantes. A vaca deve atingir seu pico de lactação entre cinco e seis semanas após o parto. Para cada kg de leite que é aumentado no pico da lactação, um aumento de 120 kg é alcançado na lactação de 305 dias. Três semanas antes do parto, a vaca reduz seu consumo em até 30%. O período de transição inclui três semanas antes e três após o parto. As vacas ao parto não devem ter mais do que quatro pontos de condição corporal. A proporção de vacas secas deve ser de 15% (12,5% de vacas secas e 2,5% de novilhas). -/- -/- REFERÊNCIAS BIBLIOGRÁFICAS -/- -/- BEARDEN, Henry Joe et al. Applied animal reproduction.

A series of recent studies have explored the impact of people's judgments regarding physical law, morality, and probability. Surprisingly, such studies indicate that these three apparently unrelated types of judgments often have precisely the same impact. We argue that these findings provide evidence for a more general hypothesis about the kind of cognition people use to think about possibilities. Specifically, we suggest that this aspect of people's cognition is best understood using an idea developed within work in the formal semantics (...) tradition, namely the notion of modality. On the view we propose, people may have separate representations for physical, moral and probabilistic considerations, but they also integrate these various considerations into a unified representation of modality.

Conceptual analysis is undergoing a revival in philosophy, and much of the credit goes to Frank Jackson. Jackson argues that conceptual analysis is needed as an integral component of so-called serious metaphysics and that it also does explanatory work in accounting for such phenomena as categorization, meaning change, communication, and linguistic understanding. He even goes so far as to argue that opponents of conceptual analysis are implicitly committed to it in practice. We show that he is wrong on all of (...) these points and that his case for conceptual analysis doesn't succeed. At the same time, we argue that the sorts of intuitions that figure in conceptual analysis may still have a significant role to play in philosophy. So naturalists needn't disregard intuitions altogether. (shrink)

By means of a comprehensive and penetrating examination of the main elements of Epicurean ethics, Phillip Mitsis forces us to reevaluate this widely misunderstood figure in the history of philosophy.

In this chapter, I survey what I call Lewisian approaches to modality: approaches that analyze modality in terms of concrete possible worlds and their parts. I take the following four theses to be characteristic of Lewisian approaches to modality. (1) There is no primitive modality. (2) There exists a plurality of concrete possible worlds. (3) Actuality is an indexical concept. (4) Modality de re is to be analyzed in terms of counterparts, not transworld identity. After an introductory section in which (...) I motivate analyzing modality in terms of possible worlds, I devote one section to each of these four theses. For each thesis, I take Lewis’s interpretation and defense as my starting point. I then consider and endorse alternative ways of accepting the thesis, some of which disagree substantially with Lewis’s interpretation or defense. There is more than one way to be a Lewisian about modality. (shrink)

Composition as identity, as I understand it, is a theory of the composite structure of reality. The theory’s underlying logic is irreducibly plural; its fundamental primitive is a generalized identity relation that takes either plural or singular arguments. Strong versions of the theory that incorporate a generalized version of the indiscernibility of identicals are incompatible with the framework of plural logic, and should be rejected. Weak versions of the theory that are based on the idea that composition is merely analogous (...) to identity are too weak to be interesting, lacking in metaphysical consequence. I defend a moderate version according to which composition is a kind of identity, and argue that the difference is metaphysically substantial, not merely terminological. I then consider whether the notion of generalized identity, though fundamental, can be elucidated in modal terms by reverse engineering Hume’s Dictum. Unfortunately, for realists about possible worlds, such as myself,... (shrink)

Dave Chappelle took an extended leave from comedy for moral reasons. I argue that, while he had every right to leave comedy because of his moral concerns, he was not obliged to do so. To make this case, I present Chappelle’s argument that the potential negative consequences of his racial humor obliged him to leave. Next, I argue against Chappelle’s argument about avoidable harms as the harms are not his responsibility, he was not being negligent, and the benefits of his (...) humor outweigh the harms. I also argue in support of the intuition that another’s failure of comprehension or moral character, even if that failure will predictably result in harms to others, should not convert moral acts into immoral ones.

This paper investigates the identity and function of τὰ μεταξύ in Aristotle and the Early Academy by focussing primarily on Aristotle’s criticisms of Xenocrates of Chalcedon, the third scholarch of Plato’s Academy and Aristotle’s direct competitor. It argues that a number of passages in Aristotle’s Metaphysics (at Β 2, Μ 1-2, and Κ 12) are chiefly directed at Xenocrates as a proponent of theories of mathematical intermediates, despite the fact that Aristotle does not mention Xenocrates there. Aristotle complains that the (...) advocates for mathematical intermediates produce theories that are ontologically and epistemologically inefficient (related to, but not confined by, the “Uniqueness Problem”); that their so-called “intermediates” feature properties opposed to those of the forms on which those intermediates are thought to depend; and that what is μεταξύ must be between objects of a different genus. In all three cases, Aristotle’s criticisms are shown to be reactions to the metaphysics and cosmology of Xenocrates, especially his doctrine of the intermediary demonic isosceles triangle souls. Xenocrates emerges as a prime candidate for Aristotle’s critique of Platonist τὰ μεταξύ theories – equal to, and possibly even exceeding, Plato as target. (shrink)

Democracy is the central political issue of our age, yet debates over its nature and goals rarely engage with feminist concerns. Now that women have the right to vote, they are thought to present no special problems of their own. But despite the seemingly gender-neutral categories of individual or citizen, democratic theory and practice continues to privilege the male. This book reconsiders dominant strands in democratic thinking - focusing on liberal democracy, participatory democracy, and twentieth century versions of civic republicanism (...) - and approaches these from a feminist perspective. Anne Phillips explores the under-representation of women in politics, the crucial relationship between public and private spheres, and the lessons of the contemporary women's movement as an experience in participatory democracy.

[Stephen Yablo] The usual charge against Carnap's internal/external distinction is one of 'guilt by association with analytic/synthetic'. But it can be freed of this association, to become the distinction between statements made within make-believe games and those made outside them-or, rather, a special case of it with some claim to be called the metaphorical/literal distinction. Not even Quine considers figurative speech committal, so this turns the tables somewhat. To determine our ontological commitments, we have to ferret out all traces (...) of nonliterality in our assertions; if there is no sensible project of doing that, there is no sensible project of Quinean ontology. /// [Andre Gallois] I discuss Steve Yablo's defence of Carnap's distinction between internal and external questions. In the first section I set out what I take that distinction, as Carnap draws it, to be, and spell out a central motivation Carnap has for invoking it. In the second section I endorse, and augment, Yablo's response to Quine's arguments against Carnap. In the third section I say why Carnap's application of the distinction between internal and external questions runs into trouble. In the fourth section I spell out what I take to be Yablo's version of Carnap. In the last I say why that version is especially vulnerable to the objection raised in the second. (shrink)

We claim that scientists working with deep learning (DL) models exhibit a form of pragmatic understanding that is not reducible to or dependent on explanation. This pragmatic understanding comprises a set of learned methodological principles that underlie DL model design-choices and secure their reliability. We illustrate this action-oriented pragmatic understanding with a case study of AlphaFold2, highlighting the interplay between background knowledge of a problem and methodological choices involving techniques for constraining how a model learns from data. Building successful models (...) requires pragmatic understanding to apply modelling strategies that encourage the model to learn data patterns that will facilitate reliable generalisation. (shrink)

Past work has demonstrated that people’s moral judgments can influence their judgments in a number of domains that might seem to involve straightforward matters of fact, including judgments about freedom, causation, the doing/allowing distinction, and intentional action. The present studies explore whether the effect of morality in these four domains can be explained by changes in the relevance of alternative possibilities. More precisely, we propose that moral judgment influences the degree to which people regard certain alternative possibilities as relevant, which (...) in turn impacts intuitions about freedom, causation, doing/allowing, and intentional action. Employing the stimuli used in previous research, Studies 1a, 2a, 3a, and 4a show that the relevance of alternatives is influenced by moral judgments and mediates the impact of morality on non-moral judgments. Studies 1b, 2b, 3b, and 4b then provide direct empirical evidence for the link between the relevance of alternatives and judgments in these four domains by manipulating (rather than measuring) the relevance of alternative possibilities. Lastly, Study 5 demonstrates that the critical mechanism is not whether alternative possibilities are considered, but whether they are regarded as relevant. These studies support a unified framework for understanding the impact of morality across these very different kinds of judgments. (shrink)

The Forrest-Armstrong argument, as reconfigured by David Lewis, is a reductio against an unrestricted principle of recombination. There is a gap in the argument which Lewis thought could be bridged by an appeal to recombination. After presenting the argument, I show that no plausible principle of recombination can bridge the gap. But other plausible principles of plenitude can bridge the gap, both principles of plenitude for world contents and principles of plenitude for world structures. I conclude that the Forrest-Armstrong argument, (...) when fortified in one of these ways, demands that unrestricted recombination be rejected. The appropriate restriction comes from a consideration of what world structures are possible. I argue that, although there are too many worlds to form a set, for any world, the individuals at that world do form a set. To defend it I invoke a principle of Limitation of Size together with an iterative conception of structure. (shrink)

Research on the capacity to understand others' minds has tended to focus on representations ofbeliefs,which are widely taken to be among the most central and basic theory of mind representations. Representations ofknowledge, by contrast, have received comparatively little attention and have often been understood as depending on prior representations of belief. After all, how could one represent someone as knowing something if one does not even represent them as believing it? Drawing on a wide range of methods across cognitive science, (...) we ask whether belief or knowledge is the more basic kind of representation. The evidence indicates that nonhuman primates attribute knowledge but not belief, that knowledge representations arise earlier in human development than belief representations, that the capacity to represent knowledge may remain intact in patient populations even when belief representation is disrupted, that knowledge (but not belief) attributions are likely automatic, and that explicit knowledge attributions are made more quickly than equivalent belief attributions. Critically, the theory of mind representations uncovered by these various methods exhibits a set of signature features clearly indicative of knowledge: they are not modality-specific, they are factive, they are not just true belief, and they allow for representations of egocentric ignorance. We argue that these signature features elucidate the primary function of knowledge representation: facilitating learning from others about the external world. This suggests a new way of understanding theory of mind – one that is focused on understanding others' minds in relation to the actual world, rather than independent from it. (shrink)

The goal of this paper is to show that the information carried by a structural representation can be decomposed into the information carried by its component parts. In particular, the relations between the components of a structural representation carry quantifiable information about the relations between components of their signifieds. It follows that the information carried by cognitive structural representations, including cognitive maps, can in principle be quantified and decomposed. This is perhaps surprising given that the formal tools of communication theory (...) have typically only been applied to simpler representation-like states without significant structure, such as detectors or indicators. In the final section I consider using computational complexity theory to capture the processing advantages afforded by structural representation. (shrink)

This article discusses whether a sense of humor is a political virtue. It argues that a sense of humor is conducive to the central political virtues. We must first, however, delineate different types of humor (benevolent or malicious) and the different political virtues (sociability, prudence, and justice) to which they correspond. Generally speaking, a sense of humor is politically virtuous when it encourages good will toward fellow citizens, an awareness of the limits of power, and a tendency not to take (...) oneself too seriously or when it condemns moral or intellectual vice. An analysis of President Donald Trumps deeply flawed sense of humor is used to ground this account. (shrink)

The Language of Thought Hypothesis is often taken to have the fatal flaw that it generates an explanatory regress. The language of thought is invoked to explain certain features of natural language (e.g., that it is learned, understood, and is meaningful), but, according to the regress argument, the language of thought itself has these same features and hence no explanatory progress has been made. We argue that such arguments rely on the tacit assumption that the entire motivation for the language (...) of thought consists in explaining the explanandum that allegedly generates the regress. But this tacit assumption is simply false. The Language of Thought Hypothesis is a cogent view and one with considerable explanatory advantages. (shrink)

In this paper I consider the merits and motivations for eliminativist error theories of absence causation, such as those offered by Beebee, Varzi, and Mumford. According to such views, there is no causation by absence. Here I argue that, despite of- fering an alternative picture of the practice of citing absences as causes, these views are inadequately motivated. I consider and reject a range of arguments for error-theoretic approaches, including appeals to ontological economy, physicalism and the causal clo- sure of (...) the physical, as well as Mumford’s recent appeal to soft Parmenideanism. I also argue that the arguments in the literature which aim to show that causation by absence is conceptually problematic are less forceful than they might initially appear. The result is that there is no compelling reason yet why we should reject absence causation. (shrink)

Modern thought typically opposes the authority of tradition in the name of universal reason. Postmodernism begins with the insight that the sociohistorical context of tradition and its authority is inevitable, even in modernity. Modernity can no longer take itself for granted when it recognizes itself as a tradition that is opposed to traditions. The left-wing postmodernist response to this insight is to conclude that because tradition is inevitable, irrationality is inevitable. The right-wing postmodernist response is to see traditions as the (...) home of diverse forms of rationality. This requires an understanding of the Socratic, self-critical aspect of intellectual traditions, which include both modern sciences and the great world religions. (shrink)

The paper offers a running commentary on ps-Archytas’ On Intellect and Sense Perception (composed ca. 80 BCE), with the aim to provide a clear description of Hellenistic/post-Hellenistic Pythagorean epistemology. Through an analysis of the process of knowledge and of the faculties that this involves, ps-Archytas presents an original epistemological theory which, although grounded in Aristotelian and Platonic theories, results in a peculiar Pythagorean criteriology that accounts for the acquisition and production of knowledge, as well as for the specific competences of (...) each cognitive faculty.

At the beginning of Republic 2 (358e–359b), Plato has Glaucon ascribe a social contract theory to Thrasymachus and ‘countless others’. This paper takes Glaucon’s description to refer both within the text to Thrasymachus’ views, and outside the text to a series of works, most of which have been lost, On Justice or On Law. It examines what is likely to be the earliest surviving work that presents a philosophical defence of law and justice against those who would prefer their opposites, (...) On Excellence by an anonymous author usually referred to as ‘Anonymus Iamblichi’; the views on these topics among the Socratics, including Crito, Simon the Cobbler, Aristippus of Cyrene, and Antisthenes; and Socrates’ debate with Hippias ‘On Justice’ in Xenophon’s Memorabilia (4.4.5–25). Its main contention is that the ‘countless others’ referred to by Glaucon points chiefly, but not solely, to the members of the circle of Socrates, who themselves espoused a range of views on justice and law, and their relations.

This paper critically examines the use of the name 'Pseudo-Archytas' to refer to two aspects of the reception of Archytas of Tarentum in antiquity: the 'author-inflection' and the 'authority-inflection'. In order to make progress on our understanding of authority and authorship within the Pythagorean tradition, it attempts to reconstruct Porphyry's views on the importance of Archytas as guarantor of Pythagorean authenticity in the former's lost work On the History of the Philosophers by considering a fragment preserved in Arabic by Ibn (...) Abī Uṣaybi‘a. The article finally argues that a range of problems attend our use of the term 'pseudo-Archytas', which is not fit for purpose when considering the evidence regarding authorship and authority in the Pythagorean tradition. It recommends a more critical approach to the notion of authenticity within the Pythagorean tradition and suggests a new term, 'Archytism', as a more useful point of reference. (shrink)

There has been a long history of arguments over whether happiness is anything more than a particular set of psychological states. On one side, some philosophers have argued that there is not, endorsing a descriptive view of happiness. Affective scientists have also embraced this view and are reaching a near consensus on a definition of happiness as some combination of affect and life-satisfaction. On the other side, some philosophers have maintained an evaluative view of happiness, on which being happy involves (...) living a life that is normatively good. Within the context of this debate we consider how people ordinarily understand happiness, and provide evidence that the ordinary understanding of happiness reflects aspects of both evaluative and descriptive views. Similar to evaluative views, normative judgments have a substantive role in the ordinary understanding of happiness. Yet, similar to descriptive views, the ordinary understanding is focused on the person’s psychological states and not the overall life they actually lived. Combining these two aspects, we argue that the ordinary understanding of happiness suggests a novel view on which happiness consists in experiencing positive psychological states when one ought to. This view, if right, has implications for both philosophical and psychological research on happiness. (shrink)

In 1889, the German philologist Friedrich Blass isolated a section of Chapter 20 from Iamblichus’ Exhortation to Philosophy (mid- or late 3rd Century CE) as an extract from a lost sophistic or philosophical treatise from the late 5th Century BCE. In this article, I introduce the text, which is now known as 'Anonymus Iamblichi' (or 'the anonymous work preserved in Iamblichus') by appeal to its two main contexts (source preservation and original historical composition), translate and discuss all eight surviving fragments (...) in their entirety, and provide some closing remarks about its importance to this history of democratic thought. The text itself presents a series of very carefully interwoven arguments concerning the three “parts” of excellence (ἀρετή) – wisdom, courage, and eloquence – and their successful application in society. In the course of presenting this case, Anonymus Iamblichi comments on the conditions under which one should learn to be excellent (Fragments 1-2) and the ends to which one should direct one’s excellence (Fragments 3-4); he provides an anthropological discussion of the weaknesses of human psychology and its effects on the good man (Fragments 5-6) and an hypothetical thought experiment concerning the “Superman” (which naturally solicits comparison with Nietzsche’s übermensch) and his inability to overcome the multitude in a lawless state (Fragments 6 and 8); and a positive defense of law and justice, reflecting a pro-democratic philosophical perspective (Fragments 7-8) – a rara avis indeed in ancient philosophy.

I argue that we can visually perceive others as seeing agents. I start by characterizing perceptual processes as those that are causally controlled by proximal stimuli. I then distinguish between various forms of visual perspective-taking, before presenting evidence that most of them come in perceptual varieties. In doing so, I clarify and defend the view that some forms of visual perspective-taking are “automatic”—a view that has been marshalled in support of dual-process accounts of mindreading.

A compositional semantics for anankastic conditionals (‘If you want p, you must φ’) has been elusive. Condoravdi and Lauer (2016) decisively object to all semantics that precede their own. CL's view rests on a response to *the problem of conflicting goals*; CL use an interpretation of 'want' on which an agent's desires don't conflict with her beliefs. But a proper response requires lack of conflict with the facts. CL's view fails. Anankastic conditionals are still a mystery.

THE MORAL INDEFENSIBILITY OF STANDING YOUR GROUND (Abstract) This paper examines the moral status of the central provision of Stand Your Ground laws: that people lawfully occupying public spaces are legally permitted to inflict self-defensive harm on aggressors even if the defenders can easily and safely retreat. The relation of this provision to existing theories of self-defense is examined, and critiques are offered of two attempts at defending it. Then reasons are presented for concluding that the provision is morally indefensible.

When did kosmos come to mean *the* kosmos, in the sense of ‘world-order’? I venture a new answer by examining later evidence often underutilised or dismissed by scholars. Two late doxographical accounts in which Pythagoras is said to be first to call the heavens kosmos (in the anonymous Life of Pythagoras and the fragments of Favorinus) exhibit heurematographical tendencies that place their claims in a dialectic with the early Peripatetics about the first discoverers of the mathematical structure of the universe. (...) Likewise, Xenophon and Plato refer to ‘wise men’ who nominate kosmos as the object of scientific inquiry into nature as a whole and the cosmic ‘communion’ (koinônia) between all living beings, respectively. Again, later testimonies help in identifying the anonymous ‘wise men’ by associating them with the Pythagoreans and, especially, Empedocles. As Horky argues, not only is Empedocles the earliest surviving source to use kosmos to refer to a harmonic ‘world-order’ and to illustrate cosmic ‘communities’ between oppositional pairs, but also his cosmology realises the mutual correspondence of these aspects in the cycle of love and strife. Thus, if later figures posited Pythagoras as the first to refer to the universal ‘world-order’ as the kosmos, they did so because they believed Empedocles to have been a Pythagorean natural scientist, whose combined focus on cosmology and ethics exemplified a distinctively Pythagorean approach to philosophy.

Decision theory and folk psychology both purport to represent the same phenomena: our belief-like and desire- and preference-like states. They also purport to do the same work with these representations: explain and predict our actions. But they do so with different sets of concepts. There's much at stake in whether one of these two sets of concepts can be accounted for with the other. Without such an account, we'd have two competing representations and systems of prediction and explanation, a dubious (...) dualism. Folk psychology structures our daily lives and has proven fruitful in the study of mind and ethics, while decision theory is pervasive in various disciplines, including the quantitative social sciences, especially economics, and philosophy. My interest is in accounting for folk psychology with decision theory -- in particular, for believe and wanting, which decision theory omits. Many have attempted this task for belief. (The Lockean Thesis says that there is such an account.) I take up the parallel task for wanting, which has received far less attention. I propose necessary and sufficient conditions, stated in terms of decision theory, for when you're truly said to want; I give an analogue of the Lockean Thesis for wanting. My account is an alternative to orthodox accounts that link wanting to preference (e.g. Stalnaker (1984), Lewis (1986)), which I argue are false. I argue further that want ascriptions are context-sensitive. My account explains this context-sensitivity, makes sense of conflicting desires, and accommodates phenomena that motivate traditional theses on which 'want' has multiple senses (e.g. all-things-considered vs. pro tanto).

Despite accepting Robert Talisse's pluralist critique of models of democratic legitimacy that rely on substantive images of the common good, there is insufficient reason to dismiss Dewey's thought from future attempts at a pragmatist philosophy of democracy. First, Dewey's use of substantive arguments does not prevent him from also making epistemic arguments that proceed from the general conditions of inquiry. Second, Dewey's account of the mean-ends transaction shows that ends-in-view are developed from within the process of democratic inquiry, not imposed (...) from without. Third, Talisse's model does not satisfy another general norm of inquiry - that of charity. (shrink)

Contemporary comedy audiences are accused by some comedians of being too morally sensitive to appreciate humor. To get closer to an idea of what this means, I will first briefly present the argument over audience sensitivity as found in the non-philosophical literature. Second, I then turn to the philosophical literature and begin from the idea that “funny” is a response-dependent property. I present a criticism of this response-dependence account of “funny” based in the claim that funniness is not de- termined (...) by what normal audiences actually laugh at, but by what merits laughter. Third, I argue that excessive or deficient moral sensitivity distorts audience receptivity to humor. Fourth, I turn to candidates for ideally sensitive audiences. I conclude by returning to the particular cases of supposed oversensitivity or undersensitivity to jokes to see how we might judge them. (shrink)

Bill Cosby’s immorality has raised intriguing aesthetic and ethical issues. Do the crimes that he has been convicted of lessen the aesthetic value of his stand-up and, even if we can enjoy it, should we? This article first discusses the intimate relationship between the comedian and audience. The art form itself is structurally intimate, and at the same time the comedian claims to express an authentic self on stage. After drawing an analogy between the question of the moral character of (...) comedians and the aesthetic value of their stand-up and the debate over the ethical criticism of art, this article argues that it is reasonable to find a comedian’s performance less funny, because stand-up’s artistic success relies on this intimacy. It contrasts the comedy of Bill Cosby with that of Louis C.K. C.K.’s moral flaws are much more present in his comedy, and it is therefore more difficult to find him funny. Last, it is ethically permissible to enjoy their comedy, if no harm to others results, both because it does not corrupt the audience’s character and because amusement is valuable. (shrink)

The present studies investigate how the intentions of third parties influence judgments of moral responsibility for other agents who commit immoral acts. Using cases in which an agent acts under some situational constraint brought about by a third party, we ask whether the agent is blamed less for the immoral act when the third party intended for that act to occur. Study 1 demonstrates that third-party intentions do influence judgments of blame. Study 2 finds that third-party intentions only influence moral (...) judgments when the agent's actions precisely match the third party's intention. Study 3 shows that this effect arises from changes in participants' causal perception that the third party was controlling the agent. Studies 4 and 5, respectively, show that the effect cannot be explained by changes in the distribution of blame or perceived differences in situational constraint faced by the agent. (shrink)

Reeder’s article offers a new and intriguing approach to the study of people’s ordinary understanding of freedom and constraint. On this approach, people use information about freedom and constraint as part of a quasi-scientific effort to make accurate inferences about an agent’s motives. Their beliefs about the agent’s motives then affect a wide variety of further psychological processes, including the process whereby they arrive at moral judgments. In illustrating this new approach, Reeder cites an elegant study he conducted a number (...) of years ago (Reeder & Spores, 1983). All subjects were given a vignette about a man who goes with his date to a pizza parlor and happens to come across a box that has been designated for charitable donations. In one condition, the man’s date then requests that he make a donation; in the other, she requests that he steal the money that is already in the box. In both conditions, the man chooses to comply with this request. The key question is how subjects will use his behavior to make inferences about whether he is a morally good or morally bad person. The results revealed a marked difference between conditions. When the man donated to charity, subjects were generally disinclined to conclude that he must have been a morally good person. It is as though they were thinking: ‘He didn’t just do this out of the goodness of his heart. (shrink)

In this paper, we argue for a particular informative and unified analysis of normative reasons. According to this analysis, a fact F is a reason to act in a certain way just in case it is evidence that one ought to act in that way. Similarly, F is a reason to believe a certain proposition just in case it is evidence for the truth of this proposition. Putting the relatively uncontroversial claim about reasons for belief to one side, we present (...) several arguments in favor of our analysis of reasons for action. We then turn to consider a series of objections to the analysis. We conclude that there are good reasons to accept the analysis and that the objections do not succeed. (shrink)

This paper focuses on the fact that AI is predominantly portrayed as white—in colour, ethnicity, or both. We first illustrate the prevalent Whiteness of real and imagined intelligent machines in four categories: humanoid robots, chatbots and virtual assistants, stock images of AI, and portrayals of AI in film and television. We then offer three interpretations of the Whiteness of AI, drawing on critical race theory, particularly the idea of the White racial frame. First, we examine the extent to which this (...) Whiteness might simply reflect the predominantly White milieus from which these artefacts arise. Second, we argue that to imagine machines that are intelligent, professional, or powerful is to imagine White machines because the White racial frame ascribes these attributes predominantly to White people. Third, we argue that AI racialised as White allows for a full erasure of people of colour from the White utopian imaginary. Finally, we examine potential consequences of the racialisation of AI, arguing it could exacerbate bias and misdirect concern. (shrink)

Moral assertions express attitudes, but it is unclear how. This paper examines proposals by David Copp, Stephen Barker, and myself that moral attitudes are expressed as implicature (Grice), and Copp's and Barker's claim that this supports expressivism about moral speech acts. I reject this claim on the ground that implicatures of attitude are more plausibly conversational than conventional. I argue that Copp's and my own relational theory of moral assertions is superior to the indexical theory offered by Barker and (...) Jamie Dreier, and that since the relational theory supports conversational implicatures of attitude, expressive conventions would be redundant. Furthermore, moral expressions of attitude behave like conversational and not conventional implicatures, and there are reasons for doubting that conventions of the suggested kind could exist.

ABSTRACTIn the late 1970s the big bang model of cosmology was widely accepted and interpreted as implying the universe had a beginning. At the end of that decade William Lane Craig revived an argument for God known as the Kalam Cosmological Argument based on this scientific consensus. Furthermore, he linked the big bang to the supposed biblical concept of creation ex nihilo found in Genesis. I shall critique Craig's position as expressed in a more recent update and argue that contemporary (...) cosmology no longer understands the big bang as the ultimate beginning, seriously undermining the KCA. I will further contend that book of Genesis should not be understood as describing creation ex nihilo anyway. (shrink)

Sufferers of eating disorders often hold false beliefs about their own body size. Such beliefs appear to violate norms of rationality, being neither grounded by nor responsive to appropriate forms of evidence. I defend the rationality of these beliefs. I argue that they are in fact supported by appropriate evidence, emanating from proprioceptive misperception of bodily boundaries. This argument has far‐reaching implications for the explanation and treatment of eating disorders, as well as debates over the relationship between rationality and human (...) psychology. (shrink)

You want to see the concert, but don’t want to take a long drive (even though the concert is far away). Such *strongly conflicting desire ascriptions* are, I show, wrongly predicted incompatible by standard semantics. I then object to possible solutions, and give my own, based on *some-things-considered desire*. Considering the fun of the concert, but ignoring the drive, you want to see the concert; considering the boredom of the drive, but ignoring the concert, you don’t want to take the (...) drive.

In November 2022, OpenAI released ChatGPT, an incredibly sophisticated chatbot. Its capability is astonishing: as well as conversing with human interlocutors, it can answer questions about history, explain almost anything you might think to ask it, and write poetry. This level of achievement has provoked interest in questions about whether a chatbot might have something similar to human intelligence or even consciousness. Given that the function of a chatbot is to process linguistic input and produce linguistic output, we consider the (...) question whether a sophisticated chatbot might have inner speech. That is: Might it talk to itself, internally? We explored this via a conversation with ‘Playground’, a chatbot which is very similar to ChatGPT but more flexible in certain respects. We asked it questions which, plausibly, can only be answered if one first produces some inner speech. Here, we present our findings and discuss their philosophical significance. (shrink)

Over the last fifteen years, an ambitious explanatory framework has been proposed to unify explanations across biology and cognitive science. Active inference, whose most famous tenet is the free energy principle, has inspired excitement and confusion in equal measure. Here, we lay the ground for proper critical analysis of active inference, in three ways. First, we give simplified versions of its core mathematical models. Second, we outline the historical development of active inference and its relationship to other theoretical approaches. Third, (...) we describe three different kinds of claim -- labelled mathematical, empirical and general -- routinely made by proponents of the framework, and suggest dialectical links between them. Overall, we aim to increase philosophical understanding of active inference so that it may be more readily evaluated. -/- This the final submitted version of the Introduction to the Topical Collection "The Free Energy Principle: From Biology to Cognition", forthcoming in Biology & Philosophy.

A mythopoetic paradigm or perspective sees the world primarily as a dramatic story of competing personal intentions, rather than a system of objective impersonal laws. Asma argued that our contemporary imaginative cognition is evolutionarily conserved-it has structural and functional similarities to premodern Homo sapiens’s cognition. This article will outline the essential features of mythopoetic cognition or adaptive imagination, delineate the adaptive sociocultural advantages of mythopoetic cognition, explain the phylogenetic and ontogenetic mechanisms that give rise to human mythopoetic mind, show how (...) mythopoetic cognition challeng­es contemporary trends in cognitive science and philosophy, and recognize and outline empirical approaches for a new cognitive science of the imagination.

Three of the chief questions this essay addresses are: 1. What justifies considering Hegel and Maimonides together in a probe of the philosophical psychology of prophetic intelligence? 2. What bearing does intellectual intuition as Hegel and Maimonides understand it have on prophecy approached from this standpoint? 3. How does the relation between intelligence and intuition and prophecy, when explored in light of the answer to the first two questions, deepen our contemporary understanding of prophecy in ways that are both philosophically (...) and religiously significant?

This chapter pursues an understanding of what Cicero thought 'Italic' philosophy to be, and proceeds to develop a broader account of how Cicero's version compares with the surviving textual evidence and testimonia from the Hellenistic period of the philosophy of the 'Italic' philosophers, including the Lucanians 'Ocellus', 'Eccelus', and 'Aresas/Aesara', and the Rudian Ennius. Special focus is placed on their theories of cosmology, psychology, and law. Collocation of 'Italic' with 'Pythagorean' philosophy of this era aids in building a more comprehensive (...) view of what Hellenistic Pythagoreanism may have looked like.

Levy (2021 Levy, N. (2021). Bad beliefs: Why they happen to good people. Oxford University Press.[Crossref], [Google Scholar]) argues that bad beliefs predominately stem from automatic (albeit rational) updating in response to testimonial evidence. To counteract such beliefs, then, we should focus on ridding our epistemic environments of misleading testimony. This paper responds as follows. First, I argue that the suite of automatic processes related to bad beliefs extends well beyond the deference-based processes that Levy identifies. Second, I push back (...) against Levy’s claim that bad beliefs stem from wholly rational processes, suggesting that, in many cases, such processes are better characterized as arational. Finally, I note that Levy is too quick to dismiss the role that individuals can play in cleaning up their own epistemic environments, and I suggest one route through which this is possible. (shrink)

Guided by neuroscience, animal behavior, evolution, philosophy, and psychology, Asma burrows deep into the human psyche to look right at the enigmatic but powerful engine that is our improvisational creativity—the source, he argues, of our remarkable imaginational capacity. How is it, he asks, that a story can evoke a whole world inside of us? How are we able to rehearse a skill, a speech, or even an entire scenario simply by thinking about it? How does creativity go beyond experience and (...) help us make something completely new? And how does our moral imagination help us sculpt a better society? As he shows, we live in a world that is only partly happening in reality. Huge swaths of our cognitive experiences are made up by “what-ifs,” “almosts,” and “maybes,” an imagined terrain that churns out one of the most overlooked but necessary resources for our flourishing: possibilities. Considering everything from how imagination works in our physical bodies to the ways we make images, from the mechanics of language and our ability to tell stories to the creative composition of self-consciousness, Asma expands our personal and day-to-day forms of imagination into a grand scale: as one of the decisive evolutionary forces that has guided human development from the Paleolithic era to today. The result is an inspiring look at the rich relationships among improvisation, imagination, and culture, and a privileged glimpse into the unique nature of our evolved minds. (shrink)
