This paper seeks to clarify and defend the proposition that moral realism is best elaborated as a moral doctrine. I begin by upholding Ronald Dworkin’s anti-Archimedean critique of the error theory against some strictures by Michael Smith, and I then briefly suggest how a proponent of moral realism as a moral doctrine would respond to Smith’s defense of the Archimedeanism of expressivism. Thereafter, this paper moves to its chief endeavor. By differentiating clearly between expressivism and quasi-realism, the paper highlights both (...) their distinctness and their compatibility. In so doing, it underscores the affinities between Blackburnian quasi-realism and moral realism as a moral doctrine. Finally, this paper contends—in line with my earlier work on these matters—that moral realism as a moral doctrine points to the need for some reorienting of meta-ethical enquiries rather than for the abandoning of them.

In Legality Scott Shapiro seeks to provide the motivation for the development of his own elaborate account of law by undertaking a critique of H.L.A. Hart's jurisprudential theory. Hart maintained that every legal system is underlain by a rule of recognition through which officials of the system identify the norms that belong to the system as laws. Shapiro argues that Hart's remarks on the rule of recognition are confused and that his model of lawis consequently untenable. Shapiro contends that a (...) new approach is vital for progress in the philosophy of law and, with his lengthy presentation of his own Planning Theory of Law, he aspires to pioneer just such an approach. Except for a very terse observation in the final main section, this article does not directly assess the strengths and shortcomings of Shapiro's piquant planning theory. Instead, I defend Hart against Shapiro's charges and thereby undermine the motivation for the development of the planning theory. (shrink)

In this paper we show that being blameworthy for not blaming and being blameworthy for victim blaming are structurally similar. Each involve the two traditional contours of moral responsibility: a knowledge condition and a control condition. But interestingly, in these cases knowledge and control are importantly interrelated. Being in a relationship with another person affords us varying degrees of knowledge about them. This knowledge in turn affords agents in relationships varying degrees of influence over one another. Cases where an agent (...) is especially blameworthy for failing to blame a friend, a close colleague, or a spouse highlight this. The interdependence of these two conditions in interpersonal relationships sheds (partial) light on why victim blaming is morally wrong. We argue that victim blamers suffer from a kind of moral myopia by only focusing on what the victim could do, in virtue of their being in a relationship of some sort with their abuser, to avoid abuse. We focus specifically on cases where such moral myopia is fueled by misogynistic and hierarchical gender schema and scripts. (shrink)

According to the probabilistic relevance account of confirmation, E confirms H relative to background knowledge K just in case P(H/K&E) > P(H/K). This requires an inequality between the rational degree of belief in H determined relative to two bodies of total knowledge which are such that one (K&E) includes the other (K) as a proper part. In this paper, I argue that it is quite plausible that there are no two possible bodies of total knowledge for ideally rational agents meeting (...) this requirement. Hence, the positive relevance account may have to be rejected. (shrink)

H. L. A. Hart’s (1907-1992) influence on contemporary philosophy is not restricted to the philosophy of law. As the book’s sub-title suggests and the table of contents confirm, he wrote widely on matters social, political and moral, not just legal. Probably best known for The Concept of Law (1961), Hart also authored a collection of essays on Jeremy Bentham (Essays on Bentham,1982), two books on the morality of criminal law based on his exchange with Lord Patrick Devlin (Law, Liberty and (...) Morality, 1963) and The Morality of the Criminal Law, 1965), one on punishment (Punishment and Responsibility, 1968), a treatise as well as a collection of essays on jurisprudential theory (Definition and Theory in Jurisprudence, 1953, and Essays in Jurisprudence and Philosophy, 1983), and finally a volume on legal causation, co-authored with Tony Honoré (Causation in the Law, 1959). The book under review here, on Hart’s legacy, is divided into six sections: the first is devoted to Hart’s general jurisprudential theory; the second to his writings on criminal law; the third to legal causation; the fourth to concerns of justice; the fifth to legal, political and moral rights; and the sixth and final section to matters of toleration and liberalism.

The Hoffmann reflex (H-wave) is produced by alpha-motoneuron activation in the spinal cord. A feature of this electromyography response is that it exhibits fluctuations in amplitude even during repetitive stimulation with the same intensity of current. We herein explore the hypothesis that physical training induces plastic changes in the motor system. Such changes are evaluated with the fractal dimension (FD) analysis of the H-wave amplitude-fluctuations (H-wave FD) and the cross-covariance (CCV) between the bilateral H-wave amplitudes. The aim of this study (...) was to compare the H-wave FD as well as the CCV before and after track training in sedentary individuals and athletes. The training modality in all subjects consisted of running three times per week (for 13 weeks) in a concrete road of 5 km. Given the different physical condition of sedentary vs. athletes, the running time between sedentary and athletes was different. After training, the FD was significantly increased in sedentary individuals but significantly reduced in athletes, although there were no changes in spinal excitability in either group of subjects. Moreover, the CCV between bilateral H-waves exhibited a significant increase in athletes but not in sedentary individuals. These differential changes in the FD and CCV indicate that the plastic changes in the complexity of the H-wave amplitude fluctuations as well as the synaptic inputs to the Ia-motoneuron systems of both legs were correlated to the previous fitness history of the subjects. Furthermore, these findings demonstrate that the FD and CCV can be employed as indexes to study plastic changes in the human motor system. (shrink)

The thesis that follows proffers a solution to the mind-matter problem, the problem as to how mind and matter relate. The proposed solution herein is a variant of panpsychism – the theory that all (pan) has minds (psyche) – that we name pansentient monism. By defining the suffix 'psyche' of panpsychism, i.e. by analysing what 'mind' is (Chapter 1), we thereby initiate the effacement of the distinction between mind and matter, and thus advance a monism. We thereafter critically examine the (...) prevalent view, antithetical to a pansentient monism, that mind is not identical to matter but emergent therefrom (Chapter 2). This anti-emergentist critique acts also as a fortification of the Genetic Argument for panpsychism: if mind is not emergent (nor distinct) from matter, mind must always have existed with matter. But what is 'matter'? Chapter 3 investigates what we understand by 'matter', or 'the physical', and exposes it as a highly deficient concept and percept that in concreto points to its identity with that denoted by 'mind'. This also acts as a fortification of the Abstraction Argument for panpsychism, employing a new taxonomy of physicalism and a new taxonomy of the varieties of abstraction. Thus do we reach a monism that is a parsimonious psycho-physical identity theory. But here we face what can be called The Identity Problem for Panpsychism: if our panpsychism is a psycho-physical identity theory, how can it respond to the powerful objections that beset the identity theory of the twentieth century? In Chapter 4 it will be argued that, like emergentism, this psycho-neural identity theory presupposed a deficient concept of 'matter', down to which mind was reduced away, let alone identified. But to identify down phenomena to what is actually an abstraction is to commit failure of explanation. When the theory is amended accordingly, we move from a psycho-neural identity theory to a genuine psycho-physical identity theory that as such can overcome the aforementioned identity problem. Furthermore, as Chapter 5 clarifies, our pansentient monism has, in addition to parsimony, the explanatory power to resolve the problem of mental causation that afflicts both the reductive physicalism of psycho-neural identity theory and the non-reductive physicalism of emergentism, by genuinely identifying physical and mental causation. Jaegwon Kim considers the place of consciousness in a physical world and the nature of mental causation to be the two key components of the mind-matter problem. Through the critical analysis of our prosaic understanding of mind and matter in this thesis, which incorporates the thought of both classical and contemporary thinkers through a novel fusion, it is hoped that both components are addressed and redressed. That is to say that I present this pansentient monism as a plausible, parsimonious, explanatory, and thus, I think, powerful position towards this ever-perplexing mind-matter mystery. -/- [This thesis was passed in January 2019 with viva examination from Galen Strawson and Joel Krueger.

Some time ago, Joel Katzav and Brian Ellis debated the compatibility of dispositional essentialism with the principle of least action. Surprisingly, very little has been said on the matter since, even by the most naturalistically inclined metaphysicians. Here, we revisit the Katzav–Ellis arguments of 2004–05. We outline the two problems for the dispositionalist identified Katzav in his 2004 , and claim they are not as problematic for the dispositional essentialist at it first seems – but not for the reasons (...) espoused by Ellis.

This paper offers a brief account of Finnis' Natural Law Legal Theory (NLLT), primarily as it is presented in Natural Law and Natural Rights, and then defends Finnis' NLLT against the recent legal positivist criticism made by Matthew H. Kramer.

OBJETIVO -/- O estudante de Zootecnia e de Veterinária, quando se depara com a produção animal, um dos pilares importantes é a reprodução, uma vez que é a perpetuação da espécie, seja para gerar filhas de uma vaca campeã em produção leiteira e de um touro com rusticidade e com aptidão produtiva de corte, ou mesmo para reposição de um plantel, o mesmo deve estar consciente de que esse ramo é de extrema responsabilidade, já que estará intimamente lidando com a (...) vida e com um investimento que pode gerar lucros em demasia para a propriedade ou, se mal feito o manejo da reprodução, trazer sérios transtornos para a mesma. -/- Nesse trabalho, o estudante revisará os sucessos da puberdade e estacionalidade reprodutiva relacionando-os com os processos endócrinos e os fatores que afetam sua manifestação como os nutricionais, para compreender a maneira ao qual podem ser manipuladas. -/- -/- • _____INTRODUÇÃO -/- A puberdade marca o início da vida reprodutiva do animal, permitindo integrar o indivíduo ao seu ciclo produtivo. A estacionalidade é uma característica de adaptação que algumas espécies desenvolveram para fazer garantir a eficiência da reprodução e a sobrevivência dos filhotes. -/- -/- • _____PUBERDADE -/- A puberdade é atingida quando o animal é capaz de produzir e liberar gametas viáveis e funcionais (férteis). Na fêmea esse fato ocorre na primeira ovulação, que geralmente coincide com a manifestação do comportamento do cio; e nos machos durante a primeira ejaculação com espermatozoides viáveis. -/- Do ponto de vista da produção animal, puberdade prematura ou precoce, é importante para poder permitir a incorporação dos animais ao ciclo produtivo o mais rapidamente possível. No caso de touros holandeses, por exemplo, é desejável que produzam sêmen precocemente para incorporá-los a prova de progênie; nas fêmeas, entretanto, deve-se considerar que nem sempre é conveniente usar o primeiro ciclo ou cio para reprodução. É o caso das marrãs (porcas primíparas), onde é benéfico esperar até o segundo ou terceiro estro para aumentar o tamanho da ninhada. Também pode ser vantajoso esperar que o indivíduo alcance sua maturidade sexual, que ocorre quando a fêmea consegue se reproduzir sem sofrer efeitos adversos. A ovelha nascida na primavera, por exemplo, pode engravidar no outono seguinte e dar à luz no primeiro ano de vida, mas seu crescimento pode ser afetado; o mesmo ocorre com a novilha, em que o acasalamento precoce pode promover distorcia por falta de desenvolvimento pélvico. -/- A puberdade é um processo gradual e está intimamente relacionada à taxa de crescimento e ao metabolismo energético. O recém-nascido usa energia para funções vitais, principalmente termorregulação; esse feito se deve ao fato de os jovens possuírem uma superfície corporal muito elevada em relação ao seu volume. Durante o desenvolvi-mento subsequente dos tecidos também há prioridade no uso de nutrientes, que inicialmente favorecem o desenvolvimento do tecido ósseo e muscular, e uma vez que estes atingem determinado tamanho de acordo com as condições genéticas do indivíduo, inicia-se o desenvolvimento do tecido adiposo, que é indicativa de um reservatório de energia. É importante ressaltar que existe uma interação entre a genética e o meio ambiente, de forma que o potencial genético só será expresso se o meio ambiente for favorável. -/- Para que a ovulação ocorra, é necessário considerar o funcionamento do eixo hipotálamo-hipófise-gonodal. O aumento da frequência pulsátil do GnRH hipotalâmico e em consequência do LH hipofisário provoca a maturação do folículo em nível gonodal, o que aumenta a produção de estrógenos. O aumento dos estrogênios causa, por feedback positivo no hipotálamo, a liberação do pico pré-ovulatório de LH e, consequentemente, a ovulação. Na fase pré-púbere, a frequência dos pulsos de GnRH e LH é muito baixa e insuficiente para provocar a maturação folicular, pois o hipotálamo é inibido e, portanto, não ocorre ovulação. -/- A geração pulsátil de GnRH no momento reprodutivo adequado para desencadear o início da puberdade depende de uma rede neural complexa que, além dos neurônios GnRH, inclui outros neurônios e células da glia; ele também integra vários sinais internos e externos para o corpo. A morfologia dos neurônios GnRH também é única, uma vez que seus dendritos também podem funcionar como axônios, dando-lhes uma função distinta. A geração de pulsos também indica a necessidade de sincronização entre subpopulações de neurônios GnRH, que, acima de tudo, parece ser extrínseca a esses neurônios e envolve múltiplos hormônios e neurotransmissores -/- Se dois níveis de conexões aferentes são considerados, estima-se que cada neurônio de GnRH pode ser conectado a cerca de cinco milhões de outros neurônios; milhares de genes, então, podem estar envolvidos no processo da puberdade. A importância funcional e hierárquica de cada um desses genes no controle dos neurônios GnRH, juntamente com outros fatores neuronais e gliais, pode diferir entre as espécies. Existem, no entanto, componentes fundamentais que parecem ser comuns a todos os mamíferos e que se situam nos níveis hierárquicos mais elevados, ajudando a compreender a progressão do processo puberal. Assim, todas as espécies de mamíferos estudadas, por exemplo, têm aglomerados de neurônios kisspeptinérgicos (que secretam kisspeptina), envolvidos na regulação da secreção tônica e secreção cíclica de GnRH, que também se classifica como o elemento mais alto na hierarquia desse complexo neuronal após considerar os neurônios GnRH. -/- Sabe-se que o eixo hipotálamo-hipofisário-gonodal está ativo desde as primeiras fases da vida do indivíduo, mesmo antes do nascimento em certas espécies. A secreção de GnRH, no entanto, é suprimida mais tarde no desenvolvimento e permanece dessa forma até o período pré-púbere, quando será reativada gradualmente. -/- Por várias décadas, a supressão e reinicialização dos pulsos de GnRH foi atribuída a uma hipótese conhecida como teoria gonadostat que afirma que o centro tônico do hipotálamo é inibido devido à sua sensibilidade ao mecanismo de feedback negativo dos esteroides gonodais, é aumentado; portanto, o GnRH e a consequente secreção de gonadotrofinas (FSH e LH) são insuficientes para a ocorrência da maturação folicular e espermatogênese. Essa sensibilidade diminui progressivamente à medida que a puberdade se aproxima. -/- Sabe-se agora que existem fatores não gonodais que agem em paralelo com os esteroides para mediar mudanças no feedback negativo que também são específicos da espécie. -/- Na fêmea, o centro gerador de pulso cíclico também deve ser considerado, o qual é responsável por iniciar a primeira ovulação. O centro cíclico é composto por uma segunda subpopulação de neurônios GnRH que é reativada por meio de uma complexa interação entre vários sistemas neuronais inibitórios (que devem reduzir progressiva-mente sua influência) e outros sistemas excitatórios, que, por sua vez, operam por meio de diferentes neurotransmissores, como o ácido γ-amino-butírico (GABA) e seus receptores, glutamato, óxido nítrico e neuropeptídio Y (NPY). Esses fatores, juntamente com as alterações morfológicas observadas nos neurônios do GnRH à medida que a puberdade se aproxima, e com as interações e sinais aferentes das células gliais, levam a um padrão de progressão linear que culminará na reativação do centro cíclico. Esse processo era conhecido anteriormente como teoria da maturação central e faz parte das mudanças que configuram o processo para chegar à puberdade. A elevação nas concen-trações de estradiol subsequente à reativação gradual do centro gerador de pulso tônico GnRH provavelmente permitirá a maturação final do centro cíclico. -/- A forma como cada organismo estabelece o momento certo para iniciar as mudanças que levam à puberdade é conhecido; a existência de algum mecanismo neurobiológico que constitui um relógio interno pode ser considerada. No entanto, esse mecanismo afetaria principalmente o desenvolvimento neuronal no nível central; também seria difícil compará-lo com a maneira pela qual fatores externos ao indivíduo afetam o início da puberdade. Nessa perspectiva, um sistema que permita receber informações completas sobre o crescimento e desenvolvimento do indivíduo poderia ser mais prático. Os mediadores desse sistema incluem o hormônio do crescimento, IGF-I, leptina e outros substratos metabólicos. A leptina em particular, que sinaliza as reservas de tecido adiposo, é um dos elementos mais importantes e, embora não determine quando começa a puberdade, se atua como fator permissivo para que o processo progrida, uma vez que excede um nível limite. A consideração do estágio de desenvolvimento do animal para o início da puberdade era anteriormente conhecida como o peso corporal crítico ou teoria do lipostato. É importante considerar que as três teorias mencionadas não são exclusivas. -/- O mecanismo da puberdade nos machos é semelhante ao já descrito; entretanto, deve-se lembrar que no macho o centro cíclico não está ativo. À medida que a puberdade se aproxima, o crescimento testicular é desencadeado e, em ruminantes e suínos, o pênis que estava preso à mucosa prepucial é gradualmente liberado. -/- -/- • _____FATORES QUE INFLUENCIAM A PUBERDADE -/- Os animais podem manifestar a puberdade de três formas diferentes. Pode ser tardia e o animal demorar para estar apto a reprodução; precoce e o animal entrar na vida reprodutiva antes do esperado ou pode ser normal e o animal estar com boa conformação e idade. Para tanto, alguns fatores podem interferir à manifestação da puberdade pelos animais como a genética, idade e peso, nutrição, fotoperíodo e o próprio manejo adotado. -/- -/- Genética -/- O genótipo afeta a idade da puberdade, pois algumas raças são anteriores a outras. Nos bovinos, as raças europeias atingem a puberdade antes dos zebuínos, isto é, uma novilha ou novilho da raça holandesa atinge a puberdade primeiro que os animais da mesma idade e do mesmo peso da raça nelore, por exemplo. -/- Da mesma forma, as porcas da raça chinesa Meishan atingem a puberdade por volta dos 115 dias de idade, metade da idade das raças brancas. As ovelhas de raças de corte, da mesma forma, são mais precoces que os produtores de lã. As raças pequenas, da mesma forma, são geralmente mais precoces, pelo menos em bovinos (jersey x guzerá) e em caninos. Os híbridos, por outro lado, apresentam puberdade mais precoce que os puros, devido ao efeito da heterose. Por este motivo, em certas espécies são utilizadas linhas híbridas. -/- -/- Idade e peso -/- A tabela 1 mostra a idade média de início da puberdade em espécies domésticas. O peso vivo (PV) adulto é mais relevante para a idade na puberdade nos ruminantes, enquanto em suínos é menos decisivo. A tabela também apresenta a porcentagem de peso corporal necessária para a puberdade ocorrer de forma natural. -/- -/- Tabela 1: Idade e peso a puberdade das espécies domésticas -/- Espécie -/- Fêmea (meses) -/- Macho (meses) -/- PV adulto (%) -/- Gado holandês -/- 11 (8-15) -/- 11 (7-18) -/- 30-40 -/- Gado brahman -/- 19 -/- 17 -/- 45-60 -/- Caprinos e ovinos -/- 7 (4-14) -/- 7 (6-9) -/- 40-60 -/- Suínos -/- 6 (5-7) -/- 7 (5-8) -/- 75 -/- Equinos -/- 18 (12-19) -/- 14 (10-24) -/- - -/- Caninos -/- 12 (6-24) -/- 9 (5-12) -/- - -/- Felinos -/- 8 (4-12) -/- 9 (8-10) -/- - -/- Fonte: VALENCIA, 2018. -/- Nutrição -/- Como a puberdade está relacionada à taxa de crescimento, os animais que recebem uma nutrição adequada e balanceada apresentarão puberdade em uma idade mais jovem, ou seja, mais precocemente; ao contrário, a puberdade será tardia nos animais que sofreram restrição alimentar, que estão desnutridos ou que tiveram seu crescimento afetado por doenças infecciosas ou parasitárias. A superalimentação também não é recomendada, pois pode alterar tanto os sinais que são recebidos pelo hipotálamo quanto sua resposta a eles. -/- Logo, o manejo alimentar adotado deve estar de acordo com as normas estabeleci-das pelos especialistas na área, principalmente no tocante as exigências nutricionais que devem servir de regra na propriedade. Sendo assim, os animais entrarão em puberdade com as taxas de alta qualidade o que afetará positivamente na prole futura e dará retorno lucrativo ao proprietário. -/- -/- Época do ano (Fotoperíodo) -/- Em fêmeas de espécies sazonais, como ovelhas e cabras, existem certos requisitos de fotoperíodo que devem ser atendidos para que a puberdade ocorra. Nessas espécies, um período de exposição a dias longos é necessário, seguido por outro de exposição a dias curtos. Na verdade, os cordeiros e cabritos nascidos fora da estação, mesmo que tenham atingido o peso necessário, terão que esperar até o outono seguinte (a estação reprodutiva) para atingir a puberdade. Os machos, por outro lado, não estão sujeitos a essas limitações nos requisitos fotoperiódicos para apresentar a puberdade. -/- Em novilhas nascidas no outono, por outro lado, a puberdade ocorre antes de um ano de idade, no verão seguinte ou no início do outono, mais cedo do que nas nascidas na primavera, devido à exposição a longos dias durante os primeiros seis meses do ano após seu nascimento aceleram seu crescimento. Em gatos, o aumento do fotoperíodo também acelera o início da puberdade. -/- Em ovelhas e novilhas, a primeira ovulação que ocorre ao entrar na puberdade é silenciosa; ou seja, não é acompanhada de sinais comportamentais de cio como a micção frequente, inchamento da vulva, uma montando a outra e deixando-se montar etc., pois para que esse comportamento se manifeste, o sistema nervoso necessita de uma pré-sensibilização com progesterona que não estará presente até o próximo ciclo, após o desenvolvimento do corpo lúteo vindo desta primeira ovulação. -/- -/- Sociossexual -/- A interação de indivíduos da mesma espécie ou a presença ou ausência de sinais de bioestimulação, como feromônios, pode afetar o período de puberdade. A puberdade, por exemplo, é atrasada em porcas criadas individualmente em comparação com porcas criadas em grupo. Além disso, na porca, ovelha e cabra, a exposição ao macho estimula as fêmeas e a puberdade aparece mais precocemente. -/- -/- Manejo -/- Certas práticas de manejo podem acelerar a puberdade, especialmente no período pré-púbere. Em porcas próximas à puberdade, por exemplo, o estresse causado por procedimentos, como o transporte de um local para outro ou a exposição ao macho, faz com que apareça o estro em torno de sete dias após a realização do manejo mencionado. -/- -/- • _____ESTACIONALIDADE REPRODUTIVA -/- A estacionalidade ou sazonalidade reprodutiva é uma estratégia evolutiva que se desenvolveu em algumas espécies; tende a tornar a reprodução mais eficiente. Nos países de latitudes distantes do equador, o objetivo é que as crias nasçam na primavera, época do ano mais favorável, graças à abundância de alimentos e às amenas condições climáticas. No caso da ovelha, cuja gestação dura cinco meses, para que os partos ocorram na primavera, ela deve engravidar no outono (figura 1), quando os dias são curtos; enquanto a égua, tendo uma gestação de aproximadamente 11 meses, deve conceber na primavera, quando os dias são longos; assim, o parto ocorrerá na primavera do ano seguinte (figura 2). -/- -/- Figura 1: Esquema ilustrativo da estacionalidade reprodutiva na espécie ovina. Fonte: PIRES et al., 2011. -/- -/- Esta característica evolutiva desenvolvida pela seleção natural na maioria das espécies silvestres e ainda é conservado por algumas espécies domésticas, como ovelhas, cabras, cavalos e gatos. Em bovinos e suínos, ao contrário, a domesticação levou à perda quase total da estacionalidade reprodutiva. -/- A estacionalidade reprodutiva é codificada nos genes; significa então que a seleção natural favoreceu a propagação de genes que permitiam acoplar a hora do nascimento com a melhor época do ano, por isso passou a ser considerada um método anticoncepcional natural. -/- -/- Figura 2: ciclo reprodutivo anual em espécies estacionais; onde são apresentados os períodos de gestação e a forma como se agrupam os nascimentos, independentemente da época reprodutiva da espécie, em vermelho as fêmeas estão apresentando estro ou cio. Fonte: VALENCIA, 2018. -/- -/- Fotoperíodo -/- Para sincronizar o período fértil com a época mais favorável do ano, a maioria das espécies sazonais usa o fotoperíodo (quantidade de luz diária ao longo do ano). -/- Este sinal ambiental é seguro, confiável e se repete a cada ano. Ovinos e caprinos se reproduzem na época do ano em que os dias são curtos e os equinos quando são longos. O grau de sazonalidade depende da origem da raça. As raças nativas de países localizados em latitudes elevadas (> 50°,ovelhas: soay, blackface, suffolk; cabras: saanen, alpino francês, toggenburg; equinos: puro-sangue, hanoveriano) terão uma estacionalidade mais acentuada do que as latitudes menores ou mediterrâneas (ovelhas: merino; cabras: murciana granadina; equinos: quarto de milha). Também existem raças de latitudes próximas ao Equador cuja estacionalidade é baixa ou nula (ovelhas: raças de pelo, crioulas; cabras: raças africanas e asiáticas) (tabela 2). -/- Para a maioria das raças de ovinos e caprinos, a estação reprodutiva começa no final do verão e início do outono; caracteriza-se pela apresentação de ciclos estrais sucessivos, e termina no final do inverno, quando se inicia o anestro, que se caracteriza pela ausência de ovulação. Nos equinos, ocorre o contrário, uma vez que a estação reprodutiva ocorre na primavera e no verão. -/- -/- Tabela 2: Relação entre a origem da raça e o grau de estacionalidade ou sazonalidade -/- Espécie -/- Alta -/- Média -/- Baixa -/- Ovinos -/- Suffolk, raças britânicas de lã e corte -/- Merino -/- Pelibuey, crioulas -/- Caprinos -/- Saanen, alpino, toggenburg -/- Murciana granadina -/- Crioula -/- Equinos -/- Puro-sangue, hanoveriano, quarto de milha -/- - -/- Crioula, burros -/- Fonte: VALENCIA, 2018. -/- -/- Mecanismo neuroendócrino da estacionalidade -/- Durante o período de anestro, o fotoperíodo exerce efeito inibitório sobre o centro tônico do GnRH no hipotálamo, diminuindo a frequência de pulso. Consequentemente, a pulsatilidade do LH também diminui, que agora é incapaz de induzir a maturação folicular, o aumento dos estrogênios, o pico pré-ovulatório de LH e, portanto, a ovulação. -/- Isso ocorre porque durante o anestro a sensibilidade do hipotálamo ao mecanismo de feedback negativo dos estrogênios e de outros fatores de origem não gonodal é aumentada. Ao aproximar-se da estação reprodutiva, a sensibilidade hipotalâmica diminui e o aumento da pulsatilidade do GnRH causa as mudanças que culminam na ovulação. Portanto, o mecanismo endócrino do anestro estacional é semelhante ao do anestro pré-púbere e de alguns outros tipos de anestro. -/- A estacionalidade é um bom exemplo da interação entre o meio ambiente e o sistema neuroendócrino, pois o organismo é capaz de traduzir um sinal externo ambiental, como o fotoperíodo, em um sinal hormonal interno, que neste caso é a melatonina. -/- A glândula pineal secreta melatonina durante as horas de escuridão. Os animais sazonais apresentam um ritmo reprodutivo endógeno, que é regulado por janelas de fotossensibilidade, determinadas por mudanças na duração do dia. O sinal luminoso é captado pela retina e conduzido, via nervo, pelo trato retino-hipotalâmico até o núcleo supraquiasmático, que funciona como o relógio biológico do corpo. Daí o sinal viaja para o núcleo para-ventricular, depois para o gânglio cervical e, finalmente, para a glândula pineal, que responde secretando melatonina (figura 3). -/- Nas ovelhas, a estação reprodutiva começa quando a duração do dia diminui e, naturalmente, a noite aumenta; na égua, ocorre quando os dias se alongam. -/- A primavera não é necessariamente a melhor época do ano em todas as regiões do globo. Nas latitudes tropicais, a primavera coincide com a seca e não com a abundância de forragem, aspecto a ser levado em consideração ao programar a reprodução. -/- Outro ponto importante a considerar é que as raças europeias sazonais mantêm sua estacionalidade no Brasil. -/- -/- Figura 3: Mecanismo do fotoperíodo em ovinos e a melatonina. Fonte: HAFEZ, 2004. -/- -/- Estacionalidade no macho -/- O macho é menos afetado que a fêmea pelas mudanças típicas de cada época do ano, já que sua função reprodutiva não é necessariamente interrompida durante o anestro ou repouso sexual, embora a produção de hormônios reprodutivos, tamanho e tônus testicular, a libido, as características qualitativas e quantitativas do ejaculado e a fertilidade do esperma podem ser diminuídas. O nível de afetação depende do grau de sazonalidade da raça e da latitude. Por fim, os efeitos do fotoperíodo devem ser separados dos nutricionais, que também variam com a época do ano. -/- -/- REFERÊNCIAS BIBLIOGRÁFICAS -/- -/- BEARDEN, Henry Joe et al.

Niels Jørgen Cappelørn, Alastair Hannay, Bruce H Kirmmse, David D Possen, Joel D S Rasmussen, and Vanessa Rumble working with the Princeton University Press and the Søren Kierkegaard Research Center at the University of Copenhagen have produced this huge work with facsimiles etc. The review comments on Kierkegaard's shrewd observations which are applicable today in the New Media World of information skews in a COVID 19 world. Further; Kierkegaard's attack against mediocrity is commented on. This review finds Kierkegaard on (...) St Augustine of Hippo as immature. It is another thing that Kierkegaard's observations and this reviewer's extrapolations from them are not yet part of the New Media Studies's mostly platitude-filled webinars. How long will we go on about Marshall McLuhan? At least let us now learn from that most sharp of ironists: that the Press will be the Press and its mostly about optics. One wonders still how, Kierkegaard misread so much Augustine? Well, no man is an island and Kierkegaard tried to be an anonymous Christian. An impossibility. (shrink)

Self-disorders in depression and schizophrenia have been the focus of much recent work in phenomenological psychopathology. But little has been said about the role the material environment plays in shaping the affective character of these disorders. In this paper, we argue that enjoying reliable (i.e., trustworthy) access to the things and spaces around us — the constituents of our material environment — is crucial for our ability to stabilize and regulate our affective life on a day-today basis. These things and (...) spaces often play an ineliminable role in shaping what we feel and how we feel it; when we interact with them, they contribute ongoing feedback that " scaffolds " the character and temporal development of our affective experiences. However, in some psychopathological conditions, the ability to access to these things and spaces becomes disturbed. Individuals not only lose certain forms of access to the practical significance of the built environment but also to its ​ regulative​ significance, too — and the stability and organization of their affective life is compromised. In developing this view, we discuss core concepts like " affordance spaces " , " scaffolding " , and " incorporation ". We apply these concepts to two case studies, severe depression and schizophrenia, and we show why these cases support our main claim. We conclude by briefly considering implications of this view for developing intervention and treatment strategies. (shrink)

I consider the developmental origins of the socially extended mind. First, I argue that, from birth, the physical interventions caregivers use to regulate infant attention and emotion (gestures, facial expressions, direction of gaze, body orientation, patterns of touch and vocalization, etc.) are part of the infant’s socially extended mind; they are external mechanisms that enable the infant to do things she could not otherwise do, cognitively speaking. Second, I argue that these physical interventions encode the norms, values, and patterned practices (...) distinctive of their specific sociocultural milieu. Accordingly, not only do they enhance and extend the infant’s cognitive competence. They also entrain the infant to think and act in culturally appropriate ways. These physical interventions are thus arguably the earliest examples of social practices that scaffold the infant’s cognitive development and shape the development of their cultural education.

Although enactive approaches to cognition vary in terms of their character and scope, all endorse several core claims. The first is that cognition is tied to action. The second is that cognition is composed of more than just in-the-head processes; cognitive activities are externalized via features of our embodiment and in our ecological dealings with the people and things around us. I appeal to these two enactive claims to consider a view called “direct social perception” : the idea that we (...) can sometimes perceive features of other minds directly in the character of their embodiment and environmental interactions. I argue that if DSP is true, we can probably also perceive certain features of mental disorders as well. I draw upon the developmental psychologist Daniel Stern’s notion of “forms of vitality”—largely overlooked in these debates—to develop this idea, and I use autism as a case study. I argue further that an enactive approach to DSP can clarify some ways we play a regulative role in shaping the temporal and phenomenal character of the disorder in question, and it may therefore have practical significance for both the clinical and therapeutic encounter.

Philosophical work exploring the relation between cognition and the Internet is now an active area of research. Some adopt an externalist framework, arguing that the Internet should be seen as environmental scaffolding that drives and shapes cognition. However, despite growing interest in this topic, little attention has been paid to how the Internet influences our affective life — our moods, emotions, and our ability to regulate these and other feeling states. We argue that the Internet scaffolds not only cognition but (...) also affect. Using various case studies, we consider some ways that we are increasingly dependent on our Internet-enabled “techno-social niches” to regulate the contours of our own affective life and participate in the affective lives of others. We argue further that, unlike many of the other environmental resources we use to regulate affect, the Internet has distinct properties that introduce new dimensions of complexity to these regulative processes. First, it is radically social in a way many of these other resources are not. Second, it is a radically distributed and decentralized resource; no one individual or agent is responsible for the Internet’s content or its affective impact on users. Accordingly, while the Internet can profoundly augment and enrich our affective life and deepen our connection with others, there is also a distinctive kind of affective precarity built into our online endeavors as well.

Grief is, and has always been, technologically supported. From memorials and shrines to photos and saved voicemail messages, we engage with the dead through the technologies available to us. As our technologies evolve, so does how we grieve. In this paper, we consider the role chatbots might play in our grieving practices. Influenced by recent phenomenological work, we begin by thinking about the character of grief. Next, we consider work on developing “continuing bonds” with the dead. We argue that for (...) some, chatbots may play an important role in establishing these continuing bonds by helping us develop what we term “habits of intimacy”. We then turn to the “ick factor” some may feel about this prospect, focusing especially on ethical concerns raised by Patrick Stokes and Adam Buben about the risk of replacing our dead with chatbots. We argue that replacement worries are not as pressing as Stokes and Buben suggest. We resist these replacement worries by appealing to the “thin reciprocity”, as we refer to it, that such bots offer, as well as the fictionalist stance that we think users of the bots adopt when engaging with them. We conclude by briefly raising some additional concerns and highlighting future research questions. (shrink)

A family of recent externalist approaches in philosophy of mind argues that our psychological capacities are synchronically and diachronically “scaffolded” by external resources. I consider how these “scaffolded” approaches might inform debates in phenomenological psychopathology. I first introduce the idea of “affective scaffolding” and make some taxonomic distinctions. Next, I use schizophrenia as a case study to argue—along with others in phenomenological psychopathology—that schizophrenia is fundamentally a self-disturbance. However, I offer a subtle reconfiguration of these approaches. I argue that schizophrenia (...) is not simply a disruption of ipseity or minimal self-consciousness but rather a disruption of the scaffolded self, established and regulated via its ongoing engagement with the world and others. I conclude by considering how this scaffolded framework indicates the need to consider new forms of intervention and treatment. (shrink)

This paper introduces the philosophy of Grace Andrus de Laguna in order to renew interest in it. I show that, in the 1910s and 1920s, she develops ideas and arguments that are also found playing key roles in the development of analytic philosophy decades later. Further, I describe her sympathetic, but acute, criticism of pragmatism and Heideggerian ontology, and situate her work in the tradition of American, speculative philosophy. Before 1920, we will see, de Laguna appeals to multiple realizability to (...) undermine reductionism in science, to support perspectival, scientific realism and, with help from a private language argument, to favour the view that mental states are classified by behavioural, teleological roles over what came to be called ‘type physicalism’. Her view of speech, mostly developed in the 1920s, tells us that its primary role is coordinating group behaviour rather than expressing thoughts. Belief is understood in terms of its causal role, including its causal relations to other kinds of mental states, when coordinating group behaviour. Thought is similarly understood. In developing her theory of mind, de Laguna rejects the pragmatist claims that belief can be reduced to dispositions to behaviour and that thought’s function is to address specific, rather than general, problems. She also favours meaning holism and rejects the analytic–synthetic distinction. In later work, de Laguna argues that individuals’ activity of self-maintenance brings universals, conceived of as irreducible potentialities, into being and makes them increasingly determinate. Further, she identifies the existence of all individuals with forms of self-maintenance and takes the existence of people to include maintenance of the cultural world. Such a unified treatment of existence, she holds, permits making its evolution intelligible. Heidegger’s view of being is rejected for not permitting this. All de Laguna’s work, we will see, fits a vision of philosophy as the systematic, imaginative and naturalistic examination of being as well as a source of criticism of science. (shrink)

In “The Child’s Relations with Others,” Merleau-Ponty argues that certain early experiences are jointly owned in that they are numerically single experiences that are nevertheless given to more than one subject (e.g., the infant and caregiver). Call this the “joint ownership thesis” (JT). Drawing upon both Merleau-Ponty’s phenomenological analysis, as well as studies of exogenous attention and mutual affect regulation in developmental psychology, I motivate the plausibility of JT. I argue that the phenomenological structure of some early infant–caregiver dyadic exchanges (...) is best described as involving joint subjects. From birth, some experiences are constitutively social in that certain phenomenal states, such as the positive emotions that arise within these early exchanges, are jointly owned. Along the way, I consider a possible objection. I conclude by considering the explanatory significance of adopting JT. (shrink)

I use critical phenomenological resources in Tetsurō Watsuji and Sarah Ahmed to explore the spatial origin of some social impairments in Autistic Spectrum Disorder (ASD). I argue that a critical phenomenological perspective puts pressure on the idea that social impairments in ASD are exclusively (or even primarily) neurocognitive deficits that can be addressed by focusing on cognitive factors internal to the autistic person — for example, training them to adopt a more neurotypical approach to social cognition. Instead, I argue that (...) the structure and character of some neurotypical spaces may play a regulative role in shaping aspects of at least some of the social impairments autistic people exhibit when they inhabit these spaces. I also briefly consider some possible therapeutic applications of this critical phenomenological approach. (shrink)

Until recently, philosophers and psychologists conceived of emotions as brain- and body-bound affairs. But researchers have started to challenge this internalist and individualist orthodoxy. A rapidly growing body of work suggests that some emotions incorporate external resources and thus extend beyond the neurophysiological confines of organisms; some even argue that emotions can be socially extended and shared by multiple agents. Call this the extended emotions thesis. In this article, we consider different ways of understanding ExE in philosophy, psychology, and the (...) cognitive sciences. First, we outline the background of the debate and discuss different argumentative strategies for ExE. In particular, we distinguish ExE from cognate but more moderate claims about the embodied and situated nature of cognition and emotion. We then dwell upon two dimensions of ExE: emotions extended by material culture and by the social factors. We conclude by defending ExE against some objections and point to desiderata for future research. (shrink)

We argue that the notion of "mental institutions"-discussed in recent debates about extended cognition-can help better understand the origin and character of social impairments in autism, and also help illuminate the extent to which some mechanisms of autistic dysfunction extend across both internal and external factors (i.e., they do not just reside within an individual's head). After providing some conceptual background, we discuss the connection between mental institutions and embodied habits of mind. We then discuss the significance of our view (...) for understanding autistic habits of mind and consider why these embodied habits are sometimes a poor fit with neurotypical mental institutions. We conclude by considering how these insights highlight the two-way, extended nature of social impairments in autism, and how this extended picture might assist in constructing more inclusive mental institutions and intervention strategies.

There is growing philosophical interest in “affective injustice”: injustice faced by individuals specifically in their capacity as affective beings. Current debates tend to focus on affective injustice at the psychological level. In this paper, I argue that the built environment can be a vehicle for affective injustice — specifically, what Wildman et al. (2022) term “affective powerlessness”. I use resources from ecological psychology to develop this claim. I consider two cases where certain kinds of bodies are, either intentionally or unintentionally, (...) deprived of access to goods affording the development and maintenance of their subjective well-being: hostile architecture and masking practices in autism. This deprivation, I argue further, leads to a significant weakening and diminishment of their spatial agency, hinders their well-being, and in so doing gives rise to a pervasive experience of affective powerlessness. By drawing attention to these themes, I show that an ecological approach helpfully supplements existing approaches. It highlights how affective injustice can emerge via the way bodies are positioned in space, and the central role that built environments play in determining this positioning. (shrink)

Much recent work on empathy in philosophy of mind and cognitive science has been guided by the assumption that minds are composed of intracranial phenomena, perceptually inaccessible and thus unobservable to everyone but their owners. I challenge this claim. I defend the view that at least some mental states and processes—or at least some parts of some mental states and processes—are at times visible, capable of being directly perceived by others. I further argue that, despite its initial implausibility, this view (...) receives robust support from several strands of empirical research. (shrink)

Loneliness is a near-universal experience. It is particularly common for individuals with (so-called) psychopathological conditions or disorders. In this paper, we explore the experiential character of loneliness, with a specific emphasis on how social goods are experienced as absent in ways that involve a diminished sense of agency and recognition. We explore the role and experience of loneliness in three case studies: depression, anorexia nervosa, and autism. We demonstrate that even though experiences of loneliness might be common to many psychopathologies, (...) these experiences nevertheless have distinctive profiles. Specifically, we suggest that: (i) loneliness is often a core characteristic of depressive experience; (ii) loneliness can drive, and even cement, disordered eating practices and anorectic identity in anorexia nervosa; iii) loneliness is neither a core characteristic of autism nor a driver but is rather commonly experienced as stemming from social worlds, environments, and norms that fail to accommodate autistic bodies and their distinctive forms of life. We aim to do justice to the pervasiveness of loneliness in many — if not all — psychopathologies, while also highlighting the need to attend to psychopathology-specific experiences of loneliness, agency, and (non-)recognition.

Affordances are action-possibilities, ways of relating to and acting on things in our world. They help us understand how these things mean what they do and how we have bodily access to our world more generally. But what happens when this access is ruptured or impeded? I consider this question in the context of psychopathology and reports that describe this experience. I argue that thinking about the bodily consequences of losing access to everyday affordances can help us better understand these (...) reports. An affordance-based approach to psychopathology can illuminate some of the causes, as well as the experiential character and consequences, of affective disorders and diminished spatial agency in self-world disturbances. It also highlights some under-explored ethical and political dimensions of these issues that need further attention. (shrink)

Grace A. de Laguna was an American philosopher of exceptional originality. Many of the arguments and positions she developed during the early decades of the twentieth century later came to be central to analytic philosophy. These arguments and positions included, even before 1930, a critique of the analytic-synthetic distinction, a private language argument, a critique of type physicalism, a functionalist theory of mind, a critique of scientific reductionism, a methodology of research programs in science and more. Nevertheless, de Laguna identified (...) herself as a defender of the speculative vision of philosophy, a vision which, in her words, “analytic philosophy condemns.” I outline her speculative vision of philosophy as well as what is, in effect, an argument she offers against analytic philosophy. This is an argument against the view that key parts of established opinion, e.g., our best theoretical physics or most certain common sense, should be assumed to be true in order to answer philosophical questions. I go on to bring out the implications of her argument for the approaches to philosophy of Bertrand Russell, Willard V. Quine and David Lewis, and I also compare the argument to recent, related arguments against analytic philosophy. I will suggest that de Laguna offers a viable critique of analytic philosophy and an alternative approach to philosophy that meets this critique. (shrink)

The problem of other minds has a distinguished philosophical history stretching back more than two hundred years. Taken at face value, it is an epistemological question: it concerns how we can have knowledge of, or at least justified belief in, the existence of minds other than our own. In recent decades, philosophers, psychologists, neuroscientists, anthropologists and primatologists have debated a related question: how we actually go about attributing mental states to others (regardless of whether we ever achieve knowledge or rational (...) justification in this domain). Until the mid-nineties, the latter debate – which sometimes goes under the name of the “mindreading” debate – was characterized by a fairly clear-cut opposition between two theoretical outlooks: “theory-theory” (TT) and “simulation theory” (ST). Theory-theorists typically argued that we attribute mental states to others on the basis of a “theory of mind” that is either constructed in early infancy and subsequently revised and modified (Gopnik 1996), or else is the result of maturation of innate mindreading “modules” (Baron-Cohen 1995).

This paper contributes to explaining the rise of logical empiricism in mid-twentieth century (North) America and to a better understanding of American philosophy of science before the dominance of logical empiricism. We show that, contrary to a number of existing histories, philosophy of science was already a distinct subfield of philosophy, one with its own approaches and issues, even before logical empiricists arrived in America. It was a form of speculative philosophy with a concern for speculative metaphysics, normative issues relating (...) to science and society and issues which later were associated with logical empiricist philosophy of science, issues such as confirmation, scientific explanation, reductionism and laws of nature. Further, philosophy of science was not primarily pragmatist in orientation. We also show, with the help of our historical characterization, that a recent account of the emergence of analytic philosophy applies to the rise of logical empiricism. It has been argued that the emergence of American analytic philosophy is partly explained by analytic philosophers’ use of key institutions, including of journals, to marginalize speculative philosophy and promote analytic philosophy. We argue that this use of institutions included the marginalization of speculative and value-laden philosophy of science and the promotion of logical empiricism. (shrink)

Insofar as many older adults fit some definition of disability, disability studies and gerontology would seem to have common interests and goals. However, there has been little discussion between these fields. The aim of this paper is to open up the insights of disability studies as well as philosophy of disability to discussions in gerontology. In doing so, I hope to contribute to thinking about the good life in late life by more critically reflecting upon the meaning of the body, (...) ability, and the variability of each. My central argument is that we should conceptualize age‐associated bodily variations and abilities not in terms of individual capacity, but in terms of what I call “the extended body.” It is in light of the meaning of embodiment and ability in general that we must think differently and more capaciously about the meaning of late life in particular.

Dutch Book Arguments (DBAs) have been invoked to support various requirements of rationality. Some are plausible: probabilism and conditionalization. Others are less so: credal transparency and reflection. Anna Mahtani has argued for a new understanding of DBAs which, she claims, allow us to keep the DBAs for probabilism (and perhaps conditionalization) and reject the DBAs for credal transparency and reflection. I argue that Mahtani’s new account fails as (a) it does not support highly plausible requirements of rational coherence and (b) (...) it does not, even setting aside the first objection, succeed in undermining the DBAs for credal transparency or reflection.

For 4E cognitive science, minds are embodied, embedded, enacted, and extended. Proponents observe that we regularly ‘offload’ our thinking onto body and world: we use gestures and calculators to augment mathematical reasoning, and smartphones and search engines as memory aids. I argue that music is a beyond-the-head resource that affords offloading. Via this offloading, music scaffolds access to new forms of thought, experience, and behaviour. I focus on music’s capacity to scaffold emotional consciousness, including the self-regulative processes constitutive of emotional (...) consciousness. In developing this idea, I consider the ‘material’ and ‘worldmaking’ character music, and I apply these considerations to two case studies: music as a tool for religious worship, and music as a weapon for torture.

Katzav and Vaesen have argued that control by analytic philosophers of key journals, philosophy departments and at least one funding body plays a substantial role in explaining the emergence of analytic philosophy into dominance in the Anglophone world and the corresponding decline of speculative philosophy. They also argued that this use of control suggests a characterisation of analytic philosophy as, at the institutional level, a sectarian form of critical philosophy. I test these hypotheses against data about philosophy job hires at (...) key philosophy departments in the USA during the period 1930-1979, and against data about PhD completions during the period 1956-1965. I argue, further, that Katzav and Vaesen’s hypotheses can fully explain the data and are more fully able to do so than are some other key accounts of the emergence of analytic philosophy in the USA.

The extended mind thesis (EM) asserts that some cognitive processes are (partially) composed of actions consisting of the manipulation and exploitation of environmental structures. Might some processes at the root of social cognition have a similarly extended structure? In this paper, I argue that social cognition is fundamentally an interactive form of space management—the negotiation and management of ‘‘we-space”—and that some of the expressive actions involved in the negotiation and management of we-space (gesture, touch, facial and whole-body expressions) drive basic (...) processes of interpersonal understanding and thus do genuine social-cognitive work. Social interaction is a kind of extended social cognition, driven and at least partially constituted by environmental (non-neural) scaffolding. Challenging the Theory of Mind paradigm, I draw upon research from gesture studies, developmental psychology, and work on Moebius Syndrome to support this thesis. (shrink)

As technology improves, artificial systems are increasingly able to behave in human-like ways: holding a conversation; providing information, advice, and support; or taking on the role of therapist, teacher, or counsellor. This enhanced behavioural complexity, we argue, encourages deeper forms of affective engagement on the part of the human user, with the artificial agent helping to stabilise, subdue, prolong, or intensify a person's emotional condition. Here, we defend a fictionalist account of human/AI interaction, according to which these encounters involve an (...) elaborate practise of imaginative pretence: a make-believe in which the artificial agent is attributed a life of its own. We attend, specifically, to the temporal characteristics of these fictions, and to what we imagine artificial agents are doing when we are not looking at them. (shrink)

I defend a model of the musically extended mind. I consider how acts of “musicking” grant access to novel emotional experiences otherwise inaccessible. First, I discuss the idea of “musical affordances” and specify both what musical affordances are and how they invite different forms of entrainment. Next, I argue that musical affordances – via soliciting different forms of entrainment – enhance the functionality of various endogenous, emotiongranting regulative processes, drawing novel experiences out of us with an expanded complexity and phenomenal (...) character. I argue that music therefore ought to be thought of as part of the vehicle needed to realize these emotional experiences. I appeal to different sources of empirical work to develop this idea.

I outline the theoretical framework of, and three research programs within American speculative philosophy of science during the period 1900-1931. One program applies verificationism to research in psychology, one investigates the methodology of research programs, and one analyses scientific explanation and other scientific concepts. The primary sources for my outline are works by Morris Raphael Cohen, Grace Andrus de Laguna, Theodore de Laguna, Edgar Arthur Singer Jr., Harold Robert Smart, and Marie Collins Swabey. I also use my outline to provide (...) a partial comparison of American speculative philosophy of science and 1930s logical positivism. My comparison suggests that logical positivism was a proposal for substantially narrowing down and winding back American philosophy of science and was based on positions that were already problematized in the American context. -/- .

Willard V. Quine’s 1951 article, “Two Dogmas of Empiricism” (Two Dogmas) was taken to be revolutionary because it rejects the analytic-synthetic distinction and the thesis that empirical statements are confirmed individually rather than holistically. The present chapter, however, argues that the overcoming of modern philosophy already included the overcoming of these theses by Hegelians, pragmatists and two critics of Hegelianism and pragmatism, Grace and Theodore de Laguna. From this perspective, Two Dogmas offers a Hegelian epistemology that was already superseded in (...) 1910. The perspective is largely based on the de Lagunas’ 1910 book Dogmatism and Evolution: Studies in Modern Philosophy. The de Lagunas’ book also helps to make clear that the real revolution Two Dogmas participated in was the marginalisation of their work and that of other speculative philosophers. Grace de Laguna surely recognised much of this when she stood opposite Quine as he first presented Two Dogmas. (shrink)

Despite increasing interest in the work of Tetsuro Watsuji, his discussion of intentionality remains underexplored. I here develop an interpretation and application of his view. First, I unpack Watsuji’s arguments for the inherently social character of intentionality, consider how they connect with his more general discussion of embodiment and betweenness, and then situate his view alongside phenomenologists like Husserl, Heidegger, and Merleau-Ponty. Next, I argue that Watsuji’s characterization of the social character of intentionality is relevant to current discussions in phenomenological (...) psychopathology. I consider how it can help illuminate the character and structure of some anomalous experiences in schizophrenia. I argue further that this application can enrich existing attempts to connect Watsuji and psychopathology, such as those found in the work of the psychiatrist Bin Kimura. (shrink)

While there is a steadily growing literature on epistemic injustice in healthcare, there are few discussions of the role that biomedical technologies play in harming patients in their capacity as knowers. Through an analysis of newborn and pediatric genetic and genomic sequencing technologies (GSTs), I argue that biomedical technologies can lead to epistemic injustice through two primary pathways: epistemic capture and value partitioning. I close by discussing the larger ethical and political context of critical analyses of GSTs and their broader (...) implications for just and equitable healthcare delivery. (shrink)

When do probability distribution functions (PDFs) about future climate misrepresent uncertainty? How can we recognise when such misrepresentation occurs and thus avoid it in reasoning about or communicating our uncertainty? And when we should not use a PDF, what should we do instead? In this paper we address these three questions. We start by providing a classification of types of uncertainty and using this classification to illustrate when PDFs misrepresent our uncertainty in a way that may adversely affect decisions. We (...) then discuss when it is reasonable and appropriate to use a PDF to reason about or communicate uncertainty about climate. We consider two perspectives on this issue. On one, which we argue is preferable, available theory and evidence in climate science basically excludes using PDFs to represent our uncertainty. On the other, PDFs can legitimately be provided when resting on appropriate expert judgement and recognition of associated risks. Once we have specified the border between appropriate and inappropriate uses of PDFs, we explore alternatives to their use. We briefly describe two formal alternatives, namely imprecise probabilities and possibilistic distribution functions, as well as informal possibilistic alternatives. We suggest that the possibilistic alternatives are preferable. -/- . (shrink)

I defend a perceptual account of face-to-face mindreading. I begin by proposing a phenomenological constraint on our visual awareness of others' emotional expressions. I argue that to meet this constraint we require a distinction between the basic and non-basic ways people, and other things, look. I offer and defend just such an account.

Recently a number of scientists have proposed substantial changes to the practice of climate modeling, though they disagree over what those changes should be. We provide an overview and critical examination of three leading proposals: the unified approach, the hierarchy approach and the pluralist approach. The unified approach calls for an accelerated development of high-resolution models within a seamless prediction framework. The hierarchy approach calls for more attention to the development and systematic study of hierarchies of related models, with the (...) aim of advancing understanding. The pluralist approach calls for greater diversity in modeling efforts, including, on some of its variants, more attention to empirical modeling. After identifying some of the scientific and institutional challenges faced by these proposals, we consider their expected gains and costs, relative to a business-as-usual modeling scenario.We find the proposals to be complementary, having valuable synergies. But since resource limitations make it unlikely that all three will be pursued, we offer some reflections on more limited changes in climate modeling that seem well within reach and that can be expected to yield substantial benefits.

In this article, we describe a hitherto undocumented fallacy-in the sense of a mistake in reasoning-constituted by a negativity bias in the way that people attribute motives to others. We call this the "worst-motive fallacy," and we conducted two experiments to investigate it. In Experiment 1, participants expected protagonists in a variety of fictional vignettes to pursue courses of action that satisfy the protagonists' worst motive, and furthermore, participants significantly expected the protagonist to pursue a worse course of action than (...) they would prefer themselves. Experiment 2 was a preregistered attempted replication of Experiment 1, including a bigger range of vignettes; the first effect was not replicated for the new vignettes tested but was for the original set. Also, we once again found that participants expected protagonists to be more likely than they were themselves to pursue courses of action that they considered morally bad. We discuss the worst-motive fallacy's relation to other well-known biases as well as its possible evolutionary origins and its ethical consequences. (shrink)

This chapter provides the background to the American women philosophers’ works that are introduced and collected in Knowledge, Mind and Reality: An Introduction by Early Twentieth-Century American Women Philosophers. We describe the institutional context which made these works possible and their methodological and theoretical background. We also provide biographies for their authors.

I respond to the commentaries on 'Grace de Laguna's Analytic and Speculative Philosophy' offered by Peter Olen [2023], Trevor Pearce, Anthony Fisher, Marguerite La Caze and Frederique Janssen-Lauret. In doing so, I bring out some of the value of de Laguna’s perspectivism and of her treatment of modality. I also further clarify how she departs from pragmatism and from analytic philosophy, and how she relates to continental philosophy.
