Heidegger, Art, and Postmodernity offers a radical new interpretation of Heidegger's later philosophy, developing his argument that art can help lead humanity beyond the nihilistic ontotheology of the modern age. Providing pathbreaking readings of Heidegger's 'The Origin of the Work of Art' and his notoriously difficult Contributions to Philosophy, this book explains precisely what postmodernity meant for Heidegger, the greatest philosophical critic of modernity, and what it could still mean for us today. Exploring these issues, Iain D. Thomson (...) examines several postmodern works of art, including music, literature, painting and even comic books, from a post-Heideggerian perspective. Clearly written and accessible, this book will help readers gain a deeper understanding of Heidegger and his relation to postmodern theory, popular culture and art. (shrink)

In lieu of an abstract, here is a brief excerpt of the content:Reviewed by:Heidegger, Art, and Postmodernity by Iain D. ThomsonIrene McMullinIain D. Thomson. Heidegger, Art, and Postmodernity. Cambridge-New York: Cambridge University Press, 2011. Pp. xix + 245. Paper, $27.99.Iain Thomson’s Heidegger, Art, and Postmodernity is an exceptional piece of Heidegger scholarship, providing detailed, informative analysis while remaining highly readable.Thomson begins by reprising the argument from his earlier Heidegger on Ontotheology: Technology and the Politics of (...) Education (Cambridge, 2005), namely, that the concept of ontotheology is key to understanding Heidegger’s thought. Ontotheologies comprehend “the intelligible order in terms of both its innermost core [ontology] and its outermost form or ultimate expression [theology]” (10). Thomson examines Heidegger’s claim that these understandings of reality change over time, a history of being comprised of distinct metaphysical “epochs” of intelligibility. Thomson recounts Heidegger’s project as an attempt to overcome ontotheology, particularly its modern and late-modern forms, in which entities appear solely as objects for control or resources for optimization.Doing so requires cultivating a plural realism whereby entities are recognized as richer in intrinsic meaning than we can capture. Thomson shows that Heidegger’s analysis of [End Page 324] art—particularly Van Gogh’s “A Pair of Shoes”—is aimed at demonstrating how art over-flows conceptual boundaries and thereby reveals this plural givenness of meaning. With startling originality, Thomson both explains the use of the three artworks in “Origin of the Work of Art” in terms of Heidegger’s history of being and refutes Shapiro’s famous criticism, arguing that Heidegger is not suggesting that the painting simply represents a peasant woman’s shoes. Rather, it represents both the shoes and a plurality of other possible meaning gestalts suggested by the umbra of “nothingness” that surrounds the shoes—the unformed textures and colors of the background—one of which is the figure of a woman.The work prompts a gestalt shift from shoes to woman, encouraging us to recognize possibilities of meaning in the inchoate forms surrounding the shoes, and thus (Heidegger hopes) realize the inexhaustibility of meaning and the structure of intelligibility itself: namely, the ontological tension between earth and world, revealing and concealing. Any representation is only one of the many conceptual possibilities present, and art helps us accomplish a postmodern “active receptivity” that responds adequately to the inexhaustibility of being as such.The latter half of Thomson’s book engages in “applied Heidegger”: the examination of particular works to demonstrate the fruitfulness of understanding Heidegger in this way. By analyzing U2’s Achtung Baby, Moore’s Watchmen comic series, and (in a particularly informative chapter) Heidegger’s Contributions to Philosophy qua philosophical fugue, Thomson is able to pursue the implications of what “postmodernity” means for Heidegger and why it should be considered appealing.Thomson’s thought-provoking and informative book should prompt a great deal of discussion. In particular, one can ask whether such a “postmodern” condition represents what Thomson and Heidegger hope it does. Thomson suggests throughout that escaping late-modern optimization and control narratives will encourage us “to approach all things with care, humility, patience, gratitude, and perhaps... awe, reverence, and love” (212). But why should we suppose that recognizing meaning’s excessiveness and multiplicity should produce such positive responses? Is it not equally plausible that it would prompt a kind of desiccated ennui, an inability to care or commit that is rooted in the sense that there is no right answer, no right way to be? One wonders if living with such recognition is even possible, considering the view espoused throughout that intelligibility depends on tension between revealing and concealing. What is the proper place for the view that no framework of intelligibility is right or adequate, but merely captures one facet of possible meaning? Is this compatible with existentialism’s characterization of humanity in terms of the need to commit to projects that delimit a normative horizon through which the world can show up as intelligible?Further, though it seems clear that cultivating a poetic responsivity to the given plurality of meaning will help overcome Western nihilism—i.e. the view that there is no inherent meaning—it is not clear that it will move us beyond...

The debate concerning abortion abounds in miraculous narratives. Judith Jarvis Thomson has contrived the most celebrated set among related ones, to wit the “violinist analogy,” the “Good Samaritan” narrative, and the “Henry Fonda” allegory, by virtue of which, she intends, on the one hand, to argue that women’s right to autonomy outweighs the alleged fetus’s right to life, and on the other, to prove that no positive moral duties can be derived towards other persons alone from the fact that (...) a moral agent is ascribed certain rights. What this short paper endeavors to prove is that Thomson’s argumentation by analogy is a weak one, since neither the number nor the relevance of similarities invoked is adequate or satisfactory, while crucial parameters concerning the morality of abortion are being totally overlooked.

"Heidegger on Being a Sexed or Gendered Human Being" is my contribution to a Symposium dedicated to the topic "Heidegger's idea of the human being." Editor Scott Campbell requested that participants (myself, Kevin Aho, Jesús Adrián Escudero, Tricia Glazebrook, Róisín Lally, and Iain Thomson) write a 1000 word statement addressing this question. Participants read each others contributions and submitted a 500 word response. This is my original statement.

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.

Même si ce livre ne compte pas plus d’une centaine de pages, l’analyse qu’il offre de Heidegger et de sa relation à l’environnement s’avère plutôt exhaustive. Si Casey Rentmeester le fait débuter par une brève histoire du développement de la philosophie environnementale, précisant comment cette discipline a largement affaire à l’éthique appliquée et l’éthique normative, il y explique bientôt comment des philosophes tels que Naess, Thomson et Toadvine emploient aujourd’hui des méthodes non-traditionnelles — ecofeminism, ecophenomenology, deep ecology — pour (...) explorer des aspects négligés par le courant philosophique qui y domine. Avant de s’appuyer sur l’œuvre heideggérienne pour répondre aux questions peu examinées par cette tradition de pensée, l’A. décrit brièvement la manière dont certains des représentants de celle-ci — Siedel, Zimmerman et Foltz notamment — se servent de celle-là pour mieux saisir la position de l’homme dans la nature. À l’en croire, son but est double : utiliser d’abord la critique phénoménologique de la métaphysique établie par Heidegger pour montrer comment, au sein de cette dernière, notre compréhension de l’être a mené à une destruction de l’environnement, puis penser avec Heidegger pour chercher à ce problème une réponse post-métaphysique qu’il s’agirait d’esquisser si tant est qu’il y en ait une. Or, tel est le cas pour Casey Rentmeester, qui se tourne en définitive vers le taoïsme pour lui emprunter son image d’un environnement durable. (shrink)

In this article I address some questions concerning the emerging conjunction of musical research on improvisation and work in the ‘posthumanities’, in particular the theoretical results of the ‘ontological turn’ in the humanities. Engaging with the work of the composer John Cage, and George E. Lewis’s framing of Cage’s performative indeterminacy as a ‘Eurological’ practice that excludes ‘Afrological’ jazz improvisation, I examine how critical discourse on Cage and his conception of sound is relevant to the improvisation-posthumanities conjunction. After discussing some (...) criticisms of ontological and materialist approaches to sound, I consider the Actor-Network Theory (ANT) of Bruno Latour, posed as offering an alternative to these approaches. Following an examination of some limitations to ANT based around the themes of critique and abstraction, I draw from the work of Gilles Deleuze and Georgina Born to suggest that work on improvisation and the posthumanities may be fruitful, but must be part of a pluralistic mode of inquiry that does not reject critique and abstraction, as some work in the posthumanities has done. (shrink)

In this essay we will take the American experimental composer John Cage’s understanding of sound as the starting point for an evaluation of that term in the field of sound studies. Drawing together two of the most influential figures in the field, Cage’s thought and work will serve as a lens through which to engage with recent debate concerning the uptake in sound studies of the philosophy of Gilles Deleuze. In so doing we will attempt to develop a path between (...) conflicting sides of sound studies, putting forward an understanding of sound that presents it not as an uninterrogated ontological essence, nor as only a term in a discursive web, but as a problem which must be repeatedly posed anew. We will consider points where this may yet be pushed towards a reified, essentialized understanding of the nature of sound, but move to offset this by emphasizing the production of a practical process of learning and experimentation. (shrink)

When beginning to think about the relation between experimental music and the thought of Gilles Deleuze, this quotation seems to be a natural starting point. In Deleuze and Guattari’s affirmation of this phrase from John Cage they suggest a resonance between music and philosophy: in both fields the experimental approach entails a dismantling of predetermining codes and hierarchies, and with this arises the opportunity for an open-endedness that accommodates singular events and encounters. This understanding of experimentation, however, is not as (...) transparent as it seems. In the context of the uptake and critique of Deleuzian ideas in the theorisation of music and sound, as well as recent re-evaluations of the milieu of “experimental music,” critics have argued that a range of normative demands, ideological assumptions, and metaphysical reductions undermine the purported freedoms of both Cagean and Deleuzian experimentalism. -/- Here I can only deal with a small aspect of the wide historical and theoretical problem this involves; but in short my aim is to begin to construct a means through which Deleuze and Guattari’s thought can be used to help us examine some strategies that composers and performers in post-Cagean musical experimentalism developed to navigate around the demands, assumptions, and reductions of Cage’s thought. (shrink)

In what follows I offer some reflections on an ethics of listening, or perhaps more generally a philosophy of listening, that can be discerned in different forms in the experimental music that, since the 1950s, has challenged and radicalised how music is understood. I situate these reflections around three of my own concert experiences as an audience member.

Where does agency lie in musical performance? How is it expressed? Recent music scholarship has highlighted an increasingly prominent tendency to conceive of agency as not confined to any one individual or type of individual, instead being distributed across diverse individuals that can be found occupying performance situations. . This article uses two ‘percussion’ works from the 1970s by the composer John Cage, Child of Tree (1975) and its multi-performer elaboration Branches (1976), as a foil for engaging with these practical (...) and theoretical musical concerns, and for suggesting some heretofore underappreciated distinctions within the ongoing work on multi-agential performance. (shrink)

This paper is concerned with the aesthetic and discursive gap between music and contemporary art, and the recent attempts to remedy this in the field of New Music through a notion of “New Conceptualism.” It examines why, despite musical sources being central to the emergence of conceptual artistic strategies in the 1950s and ’60s, the worlds of an increasingly transmedial “generic art” and music have remained largely distinct. While it takes New Music’s New Conceptualism as its focus, it argues that (...) the perspective on New Music it takes has wider implications in music and art. It begins by defining what exactly “New Music” refers to, and outlines some of the conditions for the recent rise of conceptualism in New Music. It then takes the work of the composer Johannes Kreidler as a key example of some artistic tendencies and theoretical presuppositions in New Conceptualism. Following this it draws on work in the field of sound studies in order to critically examine the theoretical attempt to connect New Music with contemporary art that is found in the notion of “Music in the Expanded Field.” To conclude it offers some reflections on how a more robust conversation between contemporary art and New Music can begin to be conceived.

Efforts to bridge emotion theory with neurobiology can be facilitated by dynamic systems (DS) modeling. DS principles stipulate higher-order wholes emerging from lower-order constituents through bidirectional causal processes cognition relations. I then present a psychological model based on this reconceptualization, identifying trigger, self-amplification, and self-stabilization phases of emotion-appraisal states, leading to consolidating traits. The article goes on to describe neural structures and functions involved in appraisal and emotion, as well as DS mechanisms of integration by which they interact. These mechanisms (...) include nested feedback interactions, global effects of neuromodulation, vertical integration, action-monitoring, and synaptic plasticity, and they are modeled in terms of both functional integration and temporal synchronization. I end by elaborating the psychological model of emotion–appraisal states with reference to neural processes. (shrink)

This article is concerned with the status and stakes of Gilles Deleuze’s “break” with structuralism. With a particular focus on a transitional text of Deleuze, the 1967/1972 article “How Do We Recognize Structuralism?,” it asks how Deleuze understood structuralism and why, after his encounter with Félix Guattari and Guattari’s own transitional text, 1969’s “Machine and Structure,” Deleuze felt the need to break with structuralism. It argues that reading these two texts together allows us to see that Deleuze already perceived tensions (...) within the structuralist project, and argues that Guattari’s non-structural account of the machine allowed Deleuze to clarify this perception, and see it as necessitating a departure from structuralism. To close, however, it turns to recent work by philosophers such as Étienne Balibar and Patrice Maniglier that re-examines the structuralist moment and identifies an ongoing legacy that the “poststructuralism” of Deleuze and Guattari may be part of. By considering Deleuze and Guattari’s break with structuralism in light of this work, this article considers how the polemical rejection of structuralism by Deleuze and Guattari may not fully account for the ongoing legacy of the structuralist program and the persistence of a structuralist problematic in their thought.

Antiquated Classical pictures of the universe have been formative in shaping the modern idea that, to the extent change is caused, it is fixed in advance. This idea has played a role in making it seem to many that what we are discovering through science supports the exclusion of free will from models for the relevant neural and bodily changes. I argue that giving up this unwarranted notion about causation opens us to the likelihood that how a person expresses free (...) will offers unique explanatory value. I then briefly discuss some further issues with either including or excluding expressions of free will from our explanations, as well as some implications for AI and everyday life. (shrink)

The reasoning view of rational normativity claims that structural rationality is normative for reasoning. Specifically, it claims that structural rationality gives us reasons to structure deliberation in ways that respect the requirements of rationality. This paper critically assesses the reasoning view. It argues that while the reasoning view might succeed in responding to arguments against the normativity of rationality, it is in tension with the motivations for thinking that rationality is normative in the first place. Moreover, proponents of the view (...) do not offer any independent reason for thinking that the view is true. As such, we have no reason to accept the reasoning view. (shrink)

Despite overlooking religious topics, Wittgenstein’s Philosophical Investigations (PI) has had a large impact in philosophy of religion. This article surveys that influence and the reasons for it. In what follows, I first describe the reception of certain key concepts from the PI in philosophy of religion. Second, I examine a few scattered remarks on religious topics in the PI. Third, I consider the relevance of the PI for contemporary philosophy of religion. I argue that the dialogical nature of the PI, (...) allowing different generations of readers to engage it with their particular philosophical problems, is key to its longterm influence. (shrink)

What kind of technology is the piano? It was once a distinctly everyday technology. In the bourgeois home of the nineteenth century it became an emblematic figure of gendered social life, its role shifting between visually pleasing piece of furniture, source of light entertainment, and expression of cultured upbringing. It performed this role unobtrusively, acting as a transparent mediator of social relations. To the composer of concert music it was, and sometimes still is, says Samuel Wilson, like the philosopher’s table: (...) “an assumed background on which one writes.” Like other instruments standard to Western art music, the piano was designed to facilitate the production of a consistent and refined timbre. More than most other such instruments, the piano also facilitated a kind of sonic neutrality. With its wide pitch range and smoothing of the percussive attack of its predecessor instruments, the piano presented composers with a technological means of approaching composition from a seemingly objective vantage point. It exemplified, in Heideggerian terms, the instrumentality of the instrument, serving as a mediator between idea and expression that apparently adds no character of its own. -/- This notion of the invisibility, or transparency, of the mediations that musical technologies such as the piano enact is one of my areas of concern here. So too is its inverse: when these mediations become visible or opaque. Transparency has been a topic of significant recent theoretical attention. Stefanos Geroulanos, for example, has detailed how the supposed transparency of intersubjective, epistemological, and social relations was a major point of critique in postwar French thought, where the supposition of transparency was taken to suppress how the world was “complex, layered, structured, filled with heterogeneity” – and, as I will stress here, contingency. The thinkers Geroulanos considers, from Jean-Paul Sartre through to Jean-François Lyotard, can be said to be united in their refusal to invisibilise mediatedness. From a starting point of conceiving of the piano as a technological artifact, and in particular from John Cage’s ‘prepared piano,’ I will explore how a similar concern has appeared in musical contexts, albeit not without the risk of reversion back into a logic of transparency.

This article evaluates the theoretical and practical grounds of recent debates around Christoph Cox’s realist project of a ‘sonic materialism’ by returning to Gilles Deleuze, a key theoretical resource for Cox. It argues that a close engagement with Deleuze’s work in fact challenges many of the precepts of Cox’s sonic materialism, and suggests a rethinking of materialism in the context of music. Turning to some aspects of Deleuze’s work neglected by Cox, the ‘realist’ ontological inquiry Cox affirms is challenged through (...) the ‘onto-ethology’ that Deleuze and Félix Guattari develop in their A Thousand Plateaus, with this diversely constructive theory of relations explicated through musical examples from John Cage and Pauline Oliveros. To conclude, this article suggests that Deleuze can indeed be understood as subscribing to a materialism, but a materialism that is practical rather than doctrinal. (shrink)

This paper considers the role of myth and phenomenology in Pierre Schaeffer’s research into music and sound, and argues that engagement with these themes allows us to rethink the legacy and contemporary value of Schaeffer’s thought in sound studies. In light of critique of Schaeffer’s project, in particular that developed by Brian Kane and Schaeffer’s own apparent self-disavowal, this paper returns to Schaeffer’s early remarks on the “myth of the seashell” in order to examine the conditions of this critique. While (...) Kane argues that Schaeffer’s recourse to myth, coupled with his adoption of Husserlian phenomenology, leads to a closure of his inquiry and a failure to accommodate the contingency of his position, this paper argues that Schaeffer’s myth of the seashell brings into focus an open-ended, motivating phenomenological problem concerning subjectivity and objectivity that runs through his thought. Drawing on the philosophical work of Gaston Bachelard and Gilles Deleuze, this paper considers the epistemological significance of this moment in Schaeffer’s thought, suggesting a “problematic” account of the myth of the seashell that puts Schaeffer into conversation with contemporary work in epistemology.

In response to historical challenges, advocates of a sophisticated variant of scientific realism emphasize that theoretical systems can be divided into numerous constituents. Setting aside any epistemic commitment to the systems themselves, they maintain that we can justifiably believe those specific constituents that are deployed in key successful predictions. Stathis Psillos articulates an explicit criterion for discerning exactly which theoretical constituents qualify. I critique Psillos's criterion in detail. I then test the more general deployment realist intuition against a set of (...) well-known historical cases, whose significance has, I contend, been overlooked. I conclude that this sophisticated form of realism remains threatened by the historical argument that prompted it. A criterion for scientific realism Assessing the criterion A return to the crucial insight: responsibility A few case studies Assessing deployment realism. (shrink)

Here I will put forward a claim about rhythm – that rhythm is relation. To develop this I will explore the entanglement of and antagonism between two notions of the musical avant-garde and its theorization. The first of these is derived from the European classical tradition, the second concerns Afrodiasporic musical practices. This essay comes in two parts. The first will consider some music-theoretical and philosophical ideas about rhythm in the post-classical avant-garde. Here I will explore how these ideas have (...) been used to, on one hand, stage a critique of Afrodiasporic musics, and specifically jazz, and, on the other hand, diminish and obscure the relation between the post-classical and Afrodiasporic avant-gardes. In the second part I will develop another lineage of rhythm, orthogonal to that of the post-classical avant-garde. Drawing from philosophy and Afrocentric, Afromodernist and, finally, Afrofuturist theory, I will map a theoretical move from rhythm understood, in its post-classical guise, as an exclusive and strictly musical category, to rhythm understood as an inclusive and plural category. This likewise charts a passage from an aesthetically autonomous understanding of objects of art to social and collective forms of artistic practice. (shrink)

This article reconstructs Gilles Deleuze’s engagement with phenomenology, and with the phenomenological problematic of sensation, in his Francis Bacon: The Logic of Sensation. Considering Deleuze’s adoption, from the phenomenology of art, of notions of sensation and rhythm, it examines how Deleuze complexifies these phenomenological notions by aligning them with his profoundly non-phenomenological notion of the body without organs, as well as with the concepts of modulation and the diagram. In mapping Deleuze’s complexification of rhythm and his development of a logic (...) of rhythmic modulation, this article shows how Deleuze immanently refines an approach to working beyond phenomenology, through phenomenology.

Lawrence Kohlberg's Approach to Moral Education presents what the late Lawrence Kohlberg regarded as the definitive statement of his educational theory. Addressing the sociology and social psychology of schooling, the authors propose that school culture become the center of moral education and research. They discuss how schools can develop as just and cohesive communities by involving students in democracy, and they focus on the moral decisions teachers and students face as they democratically resolve problems. As the authors put it: "...we (...) propose an educational renewal of our democratic society.... We have attempted to establish schools that do more than just teach about democratic citizenship, that are themselves democratic societies.". (shrink)

In this chapter I look at some questions around the notion of experimentation in philosophy, science, and the arts, through the thought of Gaston Bachelard and Gilles Deleuze. My argument is articulated around three areas of enquiry – Bachelard’s work on the experimental sciences, Deleuze’s notion of philosophy as an experimental practice, and recent musicological debate around the practical and political stakes of the term ‘experimental music’. By drawing together these three senses of experimentation, I test the possibilities of understanding (...) experimentation as a transdisciplinary concept and/or method. I develop a notion of experimentation as open, fluid, and non-hierarchical, but also consider points where such an idea is short-circuited by the reassertion of disciplinary closure and more top-down forms of method. My frame for discussing this question is a commonly posited distinction between the experiment and the experimental. Here the experiment is something like a controlled and closed environment in which a privileged observer tests predefined hypotheses, while the experimental concerns attempts to relinquish such control and to produce contexts in which the unknown and the unexpected can arise. By turning to Bachelard’s studies of the practice of science, I will question the common conception of a disciplinary split between the experiments of science and experimental art, showing both how such a distinction cannot be so neat and how these terms are often not easily separable. Putting this notion into conjunction with recent critical discourse on experimentation in music, namely regarding the kinds of exclusions and closures that the term ‘experimental music’ has produced, and with Deleuze’s criticisms of scientific method as well as the apparent disciplinary closure of his transdisciplinary project that is present and his and Félix Guattari’s final work, What is Philosophy?, I argue that refining our understanding of experimentation as a pluralistic and fragile concept will help us engage with the difficulties raised in these fields. More generally I point towards a project of mapping out the diverse and divergent relations that a transdisciplinary understanding of experimentation may draw between philosophy, science, and art.

There is considerable disagreement about the epistemic value of novel predictive success, i.e. when a scientist predicts an unexpected phenomenon, experiments are conducted, and the prediction proves to be accurate. We survey the field on this question, noting both fully articulated views such as weak and strong predictivism, and more nascent views, such as pluralist reasons for the instrumental value of prediction. By examining the various reasons offered for the value of prediction across a range of inferential contexts , we (...) can see that neither weak nor strong predictivism captures all of the reasons for valuing prediction available. A third path is presented, Pluralist Instrumental Predictivism; PIP for short. (shrink)

Rhythm is generally taken to refer to a temporal pattern of events. Yet in recent years, across diverse fields in the arts, humanities, and social sciences, it has come to serve as the conceptual marker for a wide range of new approaches to understanding relations and relationality, following most explicitly from the late work of Henri Lefebvre. This article explores the temporal aspect of such relational thinking, in particular asking how time is implicated in relations, and how it can be (...) meaningful in those relations. The sense of time is surveyed from the perspectives of both cognition and metaphysics as well as with reference to music scholarship and social theory, and key threads are drawn, from the writings of Gaston Bachelard and Charles Sanders Peirce in particular, in order to suggest that time can be a sign, and that the signifying properties of rhythm have critical social consequences. (shrink)

I propose in this text a rhythmic theory of signs drawn from the thought of Gilles Deleuze and Félix Guattari. I name this theory a semiorhythmology. I suggest that the theory of rhythm developed in A Thousand Plateaus (1980) can be understood, in part, as the culmination of the diverse set of inquiries into signs that both Deleuze and Guattari undertook, individually and together, beginning in the 1960s. I first outline Deleuze’s theory of signs as a theory of encounter as (...) developed in Proust and Signs (1964) and Difference and Repetition (1968), following which I sketch Guattari’s engagements with signs and semiotics throughout the 1960s and 1970s, particularly through his notion of “a-signifying semiotics” and the concept of the “diagram” he adapts from the semiotics of Charles Sanders Peirce. I close by showing how these heterogeneous theories of the sign are drawn together in A Thousand Plateaus through the Spinozist reading of the ethology of Jakob von Uexküll and the theorisation of rhythm in the form of the refrain.

An interview by Alex Thomson of UKColumn on Landgrebe and Smith's book: Why Machines Will Never Rule the World. The subtitle of the book is Artificial Intelligence Without Fear, and the interview begins with the question of the supposedly imminent takeover of one profession or the other by artificial intelligence. Is there truly reason to be afraid that you will lose your job? The interview itself is titled 'Where this is no will there is no way', drawing on one (...) thesis of the book to the effect that there will never be anything like the human will on the part of a machine. This is for mathematical reasons. AI is always and in every case a matter of algorithms; thus of applied mathematics. And algorithms are not the sorts of things that can want or desire or intend to do something. It is the human will of those who work at OpenAI or google or microsoft which have given rise to the new shiny objects of AI (ChatGPT and other Large Language Models). And it is the human will of the users of these shiny objects which gives them the resources and power to work their apparent miracles. (shrink)

A review of the patterns of brain activation observed in implicit and explicit memory tasks indicates that during conscious retrieval studied items are first retrieved nonconsciously and are retained in a buffer at the extrastriate cortex. It also indicates that the awareness of the retrieved item is made possible by the activation of a reentrant signaling loop between the extrastriate and left prefrontal cortices.

Shaun Nichols has recently argued that while the folk notion of free will is associated with error, a question still remains whether the concept of free will should be eliminated or preserved. He maintains that like other eliminativist arguments in philosophy, arguments that free will is an illusion seem to depend on substantive assumptions about reference. According to free will eliminativists, people have deeply mistaken beliefs about free will and this entails that free will does not exist. However, an alternative (...) reaction is that free will does exist, we just have some deeply mistaken beliefs about it. According to Nichols, all such debates boil down to whether or not the erroneous folk term in question successfully refers or not. Since Nichols adopts the view that reference is systematically ambiguous, he maintains that in some contexts it’s appropriate to take a restrictivist view about whether a term embedded in a false theory refers, while in other contexts it’s appropriate to take a liberal view about whether a token of the very same term refers. This, according to Nichols, affords the possibility of saying that the sentence “free will exists” is false in some contexts and true in others. In this paper I argue that even if we grant Nichols his pluralistic approach to reference, there is still good reason to prefer eliminativism to preservationism with regard to free will. My argument focuses on one important difference between the concept of “free will” and other theoretical terms embedded in false theories—i.e., the role that the phenomenology of free agency plays in reference fixing.

If two theory formulations are merely different expressions of the same theory, then any problem of choosing between them cannot be due to the underdetermination of theories by data. So one might suspect that we need to be able to tell distinct theories from mere alternate formulations before we can say anything substantive about underdetermination, that we need to solve the problem of identical rivals before addressing the problem of underdetermination. Here I consider two possible solutions: Quine proposes that we (...) call two theories identical if they are equivalent under a reconstrual of predicates, but this would mishandle important cases. Another proposal is to defer to the particular judgements of actual scientists. Consideration of an historical episodethe alleged equivalence of wave and matrix mechanicsshows that this second proposal also fails. Nevertheless, I suggest, the original suspicion is wrong; there are ways to enquire into underdetermination without having solved the problem of identical rivals. (shrink)

If there is to be any progress in the debate about what sort of positive moral status Kant can give the emotions, we need a taxonomy of the terms Kant uses for these concepts. It used to be thought that Kant had little room for emotions in his ethics. In the past three decades, Marcia Baron, Paul Guyer, Barbara Herman, Nancy Sherman, Allen Wood and others have argued otherwise. Contrary to what a cursory reading of the Groundwork may indicate, Kant (...) thinks the emotions play an important role in the moral life. I want to extend the work of Baron, Guyer, Herman, Sherman and Wood in three ways. First, I will set out in a diagram Kant's taxonomy of feelings and emotions. Agreement on such a taxonomy should make it easier to evaluate debates about Kant and the emotions. Second, I will focus on a certain subclass of emotions – reason-caused affects – that have previously received little attention, even from these Kant scholars. Third, these scholars base much of their defence of Kant on his later works – especially the Metaphysics of Morals and the Anthropology – but Kant's fairly rich taxonomy of the emotions, including reason-caused affects, is clearly in place at least as early as the Critique of Judgment . I believe that the Critique of Judgment is an importantly ignored resource for understanding the moral role of the emotions for Kant. The third Critique makes positive, philosophically interesting claims about the emotions and morality. Kant emphasizes certain roles for emotions in this work that he develops to the same extent nowhere else. Nevertheless, the Critique of Judgment goes all but unmentioned by many who write on these issues. In what follows, I will defend as many of my claims as possible using the third Critique. (shrink)

It is sometimes argued that the non-therapeutic, non-consensual alteration of children‘s genitals should be discussed in two separate ethical discourses: one for girls (in which such alterations should be termed 'female genital mutilation' or FGM), and one for boys (in which such alterations should be termed 'male circumcision‘). In this article, I call into question the moral and empirical basis for such a distinction, and argue that all children - whether female, male, or indeed intersex - should be free from (...) having parts of their genitals removed unless there is a pressing medical indication.

Monists, pluralists, and particularists disagree about the structure of the best explanation of the rightness (wrongness) of actions. In this paper I argue that the availability of good moral advice gives us reason to prefer particularist theories and pluralist theories to monist theories. First, I identify two distinct roles of moral theorizing—explaining the rightness (wrongness) of actions, and providing moral advice—and I explain how these two roles are related. Next, I explain what monists, pluralists, and particularists disagree about. Finally, I (...) argue that particularists and pluralists are better situated than monists to explain why it is a good idea to think before we act, and that this gives us reason to favor particularism and pluralism over monism.

In this open peer commentary, we concur with the three target articles’ analysis and positions on abortion in the special issue on Roe v. Wade as the exercise of reproductive liberty essential for the bioethical commitment to patient autonomy and self-determination. Our proposed OPC augments that analysis by explicating more fully the concept crucial to Roe of fetal personhood. We explain that the development and use of predictive reproductive technologies over the fifty years since Roe has changed the literal image, (...) and thereby the epistemological landscape, through which a prospective parent comes to know the fetus. The logic of Roe required a legal and ethical denial of fetal personhood to prioritize maternal autonomy over claims to fetal moral personhood. Our claim is that such a denial may be more complicated today. The fetal person genetic testing and reproductive imaging now presents to prospective parents has become an increasingly individualized, distinct medicalized picture of a developing person with which a parent can either identify or differentiate. In contrast, the fetal person of Roe was an abstract and vague figure stripped of most human particulars, a pregnancy rather than the specific individualized human entity reproductive technology now presents as a person to prospective parents. We discuss the implications of this shift and call for a more capacious analysis of reproductive ethics that works towards both reproductive and disability justice. (shrink)

ABSTRACT This essay defends a qualified version of Quine's thesis of universal revisability against Chalmers's recent conditionalization-based criticisms of it. It is argued that an embodied view of cognitive processing undermines Chalmers's account of nonrevisable a priori justification, which presupposes that concepts prefigure the confirmation-relations into which they enter, so as to make such relations rationally accessible to anyone who possesses those concepts. On the view developed here, bodily interaction with the world and the accompanying subconscious processing can change subjects' (...) dispositions to apply their concepts, in ways that are not rationally accessible to them, even given a complete description of that interaction, and do not constitute a change in the content of the concepts involved. Thus a subject who treats a proposition as indefeasibly justified a priori might nevertheless significantly lower her credence in that proposition, in ways that are not accessible to the subject on the basis of her grasp of the content of the relevant concepts. This discussion has further implications concerning the role of the a priori in the philosophical enterprise. (shrink)

It seems obvious that a community of one thousand scientists working together to make discoveries and solve puzzles should arrange itself differently than would one thousand scientist-hermits working independently. Because of limited time, resources, and attention, an independent scientist can explore only some of the possible approaches to a problem. Working alone, each hermit would explore the most promising approaches. They would needlessly duplicate the work of others and would be unlikely to develop approaches which look unpromising but really have (...) tremendous potential. Contrariwise, a large community can more rigorously explore the space of possible approaches. Most scientists should work on the most promising approaches, but a smaller number can be committed to approaches that initially look less promising. Exploratory work can reveal if one of those initially unpromising approaches has unrealized potential, and more scientists can adopt it once its potential becomes more apparent. (shrink)

There are two ways that we might respond to the underdetermination of theory by data. One response, which we can call the agnostic response, is to suspend judgment: "Where scientific standards cannot guide us, we should believe nothing". Another response, which we can call the fideist response, is to believe whatever we would like to believe: "If science cannot speak to the question, then we may believe anything without science ever contradicting us". C.S. Peirce recognized these options and suggested evading (...) the dilemma. It is a Logical Maxim, he suggests, that there could be no genuine underdetermination. This is no longer a viable option in the wake of developments in modern physics, so we must face the dilemma head on. The agnostic and fideist responses to underdetermination represent fundamentally different epistemic viewpoints. Nevertheless, the choice between them is not an unresolvable struggle between incommensurable worldviews. There are legitimate considerations tugging in each direction. Given the balance of these considerations, there should be a modest presumption of agnosticism. This may conflict with Peirce's Logical Maxim, but it preserves all that we can preserve of the Peircean motivation. (shrink)

Analysis of Heidegger on Plato's Doctrine of Truth, the Cave Allegory.

In recent years noise seems to have become an interdisciplinary concept par excellence, apt to capturing important dynamics at work whether in technological, scientific, social, or aesthetic domains. But when economists, biologists, psychologists, and musicians speak of noise, are they really all referring to the same thing? In An Epistemology of Noise Cecile Malaspina takes this dispersion of the notion of noise as a starting point, and moreover accepts that, when removed from its mathematical formulation in information theory and spread (...) into diverse disciplines, noise takes on a metaphorical ambiguity. Yet rather than aiming to eliminate this ambiguity, Malaspina sets out to account for it. The key problem in An Epistemology of Noise is not to identify the legitimate usage of the concept of noise, but rather to examine what happens when noise moves between disciplines, and what the ‘noisiness’ of this movement tells us about the conditions for interdisciplinary knowledge. Noise here is both an object (or many objects) of inquiry and a condition for that inquiry, and presents us with the problem of how knowledge can find its ground in these ‘shifting sands’ (9).

During the last two decades the role of quantitative genetics in evolutionary theory has expanded considerably. Quantitative genetic-based models addressing long term phenotypic evolution, evolution in multiple environments (phenotypic plasticity) and evolution of ontogenies (developmental trajectories) have been proposed. Yet, the mathematical foundations of quantitative genetics were laid with a very different set of problems in mind (mostly the prediction of short term responses to artificial selection), and at a time in which any details of the genetic machinery were virtually (...) unknown. In this paper we discuss what a model is in population biology, and what kind of model we need in order to address the complexities of phenotypic evolution. We review the assumptions of quantitative genetics and its most recent accomplishments, together with the limitations that such assumptions impose on the modelling of some aspects of phenotypic evolution. We also discuss three alternative appr oaches to the theoretical description of evolutionary trajectories (nonlinear dynamics, complexity theory and optimization theory), and their respective advantages and limitations. We conclude by calling for a new theoretical synthesis, including quantitative genetics and not necessarily limited to the other approaches here discussed. (shrink)

Spinoza's use of the phrase “sui iuris” in the Tractatus Politicus gives rise to the following paradox. On the one hand, one is said to be sui iuris to the extent that one is rational; and to the extent that one is rational, one will steadfastly obey the laws of the state. However, Spinoza also states that to the extent that one adheres to the laws of the state, one is not sui iuris, but rather stands under the power [sub (...) potestate] of the state (TP 3/5). It seems, then, that to the extent that one is sui iuris, one will not, in fact, be sui iuris. In this paper, I offer an interpretation of Spinoza's notion of being sui iuris that enables us to overcome this paradox and sheds light on Spinoza's relationship to the republican tradition. I work towards this goal by distinguishing between two ways in which Spinoza uses the locution, which correspond to two different conceptions of power: potentia and potestas. This distinction not only allows us to save Spinoza from internal inconsistency, it also enables us to see one important way in which Spinoza stands outside of the republican tradition, since he conceives of liberty not as constituted by independence, or citizenship in a res publica, but as being sui iuris in the first sense described above: being powerful.

Dombrowski and Murdoch offer versions of the ontological argument which aim to avoid two types of objection – those concerned with the nature of the divine, and those concerned with the move from an abstract concept to a mind-independent reality. For both, the nature of the concept of God/Good entails its instantiation, and both supply a supporting argument from experience. It is only Murdoch who successfully negotiates the transition from an abstract concept to the instantiation of that concept, however, and (...) this is achieved by means of an ontological argument from moral experience which, in a reversal of the Kantian doctrine, depends ultimately on a form of the cosmological argument.

This paper sets mathematics among the sciences, despite not being empirical, because it studies relations of various sorts, like the sciences. Each empirical science studies the relations among objects, which relations determining which science. The mathematical science studies relations as such, regardless of what those relations may be or be among, how relations themselves are related. This places it at the extreme among the sciences with no objects of its own (A Subject with no Object, by J.P. Burgess and G. (...) Rosen). Examples are discussed. The historical development of written mathematics from algorithms on clay tablets to theorems with proofs is said to show that application of algorithms to specific problems and theorems to scientific objects is like allegorical interpretation. Mathematics fits into the modern scientific context because the sciences, beginning with Galileo, have been constructed in imitation of mathematics. Viewing mathematics this way does not solve any ontological problems, but it does show how mathematics avoids them. Epistemological problems, insuperable for object realism, are simplified. For example, we have access to relations among any objects that we can consider objectively, first physical objects and then mathematical objects of greater and greater abstraction. (shrink)

This paper argues against the common, often implicit view that theories are some specific kind of thing. Instead, I argue for theory concept pluralism: There are multiple distinct theory concepts which we legitimately use in different domains and for different purposes, and we should not expect this to change. The argument goes by analogy with species concept pluralism, a familiar position in philosophy of biology. I conclude by considering some consequences for philosophy of science if theory concept pluralism is correct.

One approach to science treats science as a cognitive accomplishment of individuals and defines a scientific community as an aggregate of individual inquirers. Another treats science as a fundamentally collective endeavor and defines a scientist as a member of a scientific community. Distributed cognition has been offered as a framework that could be used to reconcile these two approaches. Adam Toon has recently asked if the cognitive and the social can be friends at last. He answers that they probably cannot, (...) posing objections to the would-be rapprochement. We clarify both the animosity and the tonic proposed to resolve it, ultimately arguing that worries raised by Toon and others are uncompelling. (shrink)
