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...

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.

In this paper we analyse the ideas implicit in the style of exhibition favoured by contemporary galleries and museums, and argue that unless the audience is empowered to ascribe meaning and significance to artwork through critical dialogue, the power not only of the audience is undermined but also of art. We argue that galleries and museums preside over an experience economy devoid of art, unless (i) indeterminacy is understood, (ii) the critical rather than coercive nature of art is facilitated, and (...) (iii) the conditions for inter-subjectivity are met. (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 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.

One of the most frequently voiced criticisms of free will skepticism is that it is unable to adequately deal with criminal behavior and that the responses it would permit as justified are insufficient for acceptable social policy. This concern is fueled by two factors. The first is that one of the most prominent justifications for punishing criminals, retributivism, is incompatible with free will skepticism. The second concern is that alternative justifications that are not ruled out by the skeptical view per (...) se face significant independent moral objections (Pereboom 2014: 153). Despite these concerns, I maintain that free will skepticism leaves intact other ways to respond to criminal behavior—in particular incapacitation, rehabilitation, and alteration of relevant social conditions—and that these methods are both morally justifiable and sufficient for good social policy. The position I defend is similar to Derk Pereboom’s (2001, 2013, 2014), taking as its starting point his quarantine analogy, but it sets out to develop the quarantine model within a broader justificatory framework drawn from public health ethics. The resulting model—which I call the public health-quarantine model (Caruso 2016, 2017a)—provides a framework for justifying quarantine and criminal sanctions that is more humane than retributivism and preferable to other non-retributive alternatives. It also provides a broader approach to criminal behavior than Pereboom’s quarantine analogy does on its own since it prioritizes prevention and social justice. -/- In Section 1, I begin by (very) briefly summarizing my arguments against free will and basic desert moral responsibility. In Section 2, I then introduce and defend my public health-quarantine model, which is a non-retributive alternative to criminal punishment that prioritizes prevention and social justice. In Sections 3 and 4, I take up and respond to two general objections to the public health-quarantine model. Since objections by Michael Corrado (2016), John Lemos (2016), Saul Smilanksy (2011, 2017), and Victor Tadros (2017) have been addressed in detail elsewhere (see Pereboom 2017a; Pereboom and Caruso 2018), I will here focus on objections that have not yet been addressed. In particular, I will respond to concerns about proportionality, human dignity, and victims’ rights. I will argue that each of these concerns can be met and that in the end the public health-quarantine model offers a superior alternative to retributive punishment and other non-retributive accounts.

This research investigates 3- and 5-year-olds' relative fairness in distributing small collections of even or odd numbers of more or less desirable candies, either with an adult experimenter or between two dolls. The authors compare more than 200 children from around the world, growing up in seven highly contrasted cultural and economic contexts, from rich and poor urban areas, to small-scale traditional and rural communities. Across cultures, young children tend to optimize their own gain, not showing many signs of self-sacrifice (...) or generosity. Already by 3 years of age, self-optimizing in distributive justice is based on perspective taking and rudiments of mind reading. By 5 years, overall, children tend to show more fairness in sharing. What varies across cultures is the magnitude of young children's self-interest. More fairness (less self-interest) in distributive justice is evident by children growing up in small-scale urban and traditional societies thought to promote more collective values. (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.

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)

In terms of validity in Kripke frames, a modal formula expresses a universal monadic second-order condition. Those modal formulae which are equivalent to first-order conditions are called elementary. Modal formulae which have a certain persistence property which implies their validity in all canonical frames of modal logics axiomatized with them, and therefore their completeness, are called canonical. This is a survey of a recent and ongoing study of the class of elementary and canonical modal formulae. We summarize main ideas and (...) results, and outline further research perspectives. (shrink)

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)

Despite the growth in research in philosophy of religion over the past several decades, recent years have seen a number of critical studies of this subfield in an effort to redirect the methods and topics of inquiry. This article argues that in addition to problems of religious parochialism described by critics such as Wesley Wildman, the subfield is facing a problem of relevance. In responding to this problem, it suggests that philosophers of religion should do three things: first, be critically (...) self-aware about their aims of inquiry; second, investigate concepts used by other philosophers, scientists, and religious studies scholars to identify and dispel confusion about religions; and third, following the model of applied ethics, work to clarify concepts and advance arguments of contemporary practical urgency.

Building upon the role values take in Walton’s theory of practical reasoning, this paper will frame the question of how values should be evaluated into the broader question of what reasonable practical argumentation is. The thesis argued for is that if a positive evaluation of practical reasoning argumentation requires that the argument avoid a morally negative conclusion, then the role of values should be given a central, rather than supportive, position in practical argument evaluation.

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.

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)

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.

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.

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. (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.

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. (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.

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.

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.

What is cruelty? How and why does it matter? What do the legal rejection of cruelty and the requirements of mercy entail? This essay asks these questions of Lucius Seneca, who first articulated an agent-based conception of cruelty in the context of punishment. The hypothesis is submitted that the answers to these questions offered in Seneca's De clementia constitute one of the turning points in the evolution of practical reason in law. I conclude, however, by arguing that even the mainstream (...) punitive practices of contemporary western societies fail to meet the modest imperatives of the rejection of cruelty and the unconditionality of mercy propounded by Seneca.

We have previously argued that historical cases must be rendered canonical before they can plausibly serve as evidence for philosophical claims, where canonicity is established through a process of negotiation among historians and philosophers of science (Bolinska and Martin, 2020). Here, we extend this proposal by exploring how that negotiation might take place in practice. The working stock of historical examples that philosophers tend to employ has long been established informally, and, as a result, somewhat haphazardly. The composition of the (...) historical canon of philosophy of science is therefore path dependent, and cases often become stock examples for reasons tangential to their appropriateness for the purposes at hand. We show how the lack of rigor around the canonization of case studies has muddied the waters in selected philosophical debates. This, in turn, lays the groundwork for proposing ways in which they can be improved. (shrink)

In this paper we compare the propositional logic of Frege’s Grundgesetze der Arithmetik to modern propositional systems, and show that Frege does not have a separable propositional logic, definable in terms of primitives of Grundgesetze, that corresponds to modern formulations of the logic of “not”, “and”, “or”, and “if…then…”. Along the way we prove a number of novel results about the system of propositional logic found in Grundgesetze, and the broader system obtained by including identity. In particular, we show that (...) the propositional connectives that are definable in terms of Frege’s horizontal, negation, and conditional are exactly the connectives that fuse with the horizontal, and we show that the logical operators that are definable in terms of the horizontal, negation, the conditional, and identity are exactly the operators that are invariant with respect to permutations on the domain that leave the truth-values fixed. We conclude with some general observations regarding how Frege understood his logic, and how this understanding differs from modern views. (shrink)

Abstract: In this paper we argue that Robert Kane’s theory of free will cannot accommodate the possibility of a sinless individual who faces morally significant choices because a sinless agent cannot voluntarily accord value to an immoral desire, and we argue that Kane’s theory requires this. Since the Jesus of the historic Christian tradition is held to be sinless, we think Christians should reject Kane’s theory because it seems irreconcilable with historic Christian Christology. We consider two objections to our argument (...) and argue that both fail. (shrink)

Arguments concerning central issues of contemporary Medical Ethics often not only bear similarities, but also derive their sheer essence from notions which belong to the celebrated history of Ethics. Thus, argumentation pro euthanasia and assisted suicide which focus on the detainment of dignity and the ensuring of posthumous reputation on behalf of the moral agent is shown to echo stoic views on arête and the subordination of life to the primary human goal, namely the achievement of virtue. The progress made (...) in palliative care when seen alongside the — steadily increasing — requests for suicide, is indicative of the fact that, though pain now days can be effectively controlled, moral agents often consider the preservation of their life detrimental to the detainment of virtue or posthumous reputation. The stoic view is considered to justify elective death as a personal choice, but is deemed inadequate as well as inconsistent in the broader context of a coherent value theory. (shrink)

Recent literature contains influential arguments for variabilism, the view that we should understand proper names as analogues not of constants but of variables. In particular, proper names are said to sometimes take semantic values that are not referential but purely general. I present a counter-example to this view.

The European ideals – as well as the idea of Europe per se – are faced with a serious challenge due to recent migration crisis: it is not just the reflexes, the effectiveness and the policies, but also the consistency, the principles and the justification of the notion of the European Union that is in stake. Kant’s concept of universal hospitality could probably provide a good way out of this conundrum: while hospitality has largely been viewed as a solidarity-related imperfect (...) duty towards others, that is, a less compelling duty that allows moral agents for certain latitude concerning the occasions and the degree of its implementation, Kant’s views allow for a totally different perspective, and, in my view, a much more philosophically nuanced one: hospitality might also be considered as an autonomy-based duty owed to others, and in this respect could count as a perfect, morally compelling duty. To the extent that the concept of Europe consists in humanitarian ideals that are based upon a strong philosophical humanistic tradition, I consider my claim to be in perfect harmony with the true spirit of Europe.

Both the genetic endowment we have been equipped with, and the environment we had to be born and raised in, were not – and never are – for us to choose; both are pure luck, a random ticket in this enormously inventive cosmic lottery of existence. If it is luck that has makes us the persons we are, and since our decisions and choices depend largely on the kind of persons we are, it seems that everything we do or fail (...) to do may only be attributed to luck. This paper focuses on criminal behavior, with special emphasis on Tarde’s and Lombroso’s views, to discuss free will and agency, and their interplay with moral luck, that is, the fixed boundaries set by our nature and the circumstances that surround us.

The publication of this volume allows us to entertain feelings of contentment and confidence that this objective of the project has been accomplished. (shrink)

In this paper, we discuss the ethical concerns that may arise from the synthesis of human DNA. To date, only small stretches of DNA have been constructed, but the prospect of generating human genomes is becoming feasible. At the same time, the significance of genes for identity, health and reproduction is coming under increased scrutiny. We examine the implications of DNA synthesis and its impact on debates over the relationship with our DNA and the ownership of our genes, its potential (...) to disrupt common understandings of reproduction and privacy, and the way in which synthetic DNA challenges traditional associations between genes and identity. We explore the degree to which synthetic DNA may further undermine overgeneticised accounts of identity, health, reproduction, parenthood and privacy that are prevalent in the public domain and in some areas of policy-making. While avoiding making normative claims of our own, we conclude that there is a need for reflection on the ethical implications of these developing technologies before they are on us. (shrink)

Over decades of teaching systematic theology at Union Theological Seminary (New York), Christopher Morse has set out to salvage “dogmatics” as a postmodern theological discipline that nevertheless retains a (more or less literal) construal of the apocalyptic gospel message. This article attempts to clarify this project in conversation with William James’ best-known work on religious belief.

However there is a vexing philosophical tension in Wink’s work, one that is even reflected in the fading of mainline Protestantism as a social force. This short piece was an early (...) effort to call attention to this challenge. (shrink)

Machine learning algorithms may radically improve our ability to diagnose and treat disease. For moral, legal, and scientific reasons, it is essential that doctors and patients be able to understand and explain the predictions of these models.

In A Theory of Justice, Rawls attempts to ground intergenerational justice by "virtual representation" through a thickening of the veil of ignorance. Contractors don't know to what generation they belong. This approach is flawed and will not result in the just savings principle Rawls hopes to justify. The project of grounding intergenerational duties on a social contractarian foundation is misconceived. Non-overlapping generations do not stand in relation to one another that is central to the contractarian approach.

The focus of this paper is showing that meditation is becoming aware of awareness itself...and this awareness is a field phenomena.

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).

Abstract: Don Ross’ Economic Theory and Cognitive Science (2005) provides an elaborate philosophical defense of neoclassical economics. He argues that the central features of neoclassical theory are associated with what he calls the Robbins-Samuelson argument pattern and that it can be reconciled with recent developments in experimental and behavioral economics, as well as contemporary cognitive science. This paper argues that Ross’ Robbins-Samuelson argument pattern is not in the work of either Robbins or Samuelson and in many ways is in conflict (...) with their own versions, and defenses, of neoclassical theory.

Ethical decision-making frameworks assist in identifying the issues at stake in a particular setting and thinking through, in a methodical manner, the ethical issues that require consideration as well as the values that need to be considered and promoted. Decisions made about the use, sharing, and re-use of big data are complex and laden with values. This paper sets out an Ethics Framework for Big Data in Health and Research developed by a working group convened by the Science, Health and (...) Policy-relevant Ethics in Singapore Initiative. It presents the aim and rationale for this framework supported by the underlying ethical concerns that relate to all health and research contexts. It also describes a set of substantive and procedural values that can be weighed up in addressing these concerns, and a step-by-step process for identifying, considering, and resolving the ethical issues arising from big data uses in health and research. This Framework is subsequently applied in the papers published in this Special Issue. These papers each address one of six domains where big data is currently employed: openness in big data and data repositories, precision medicine and big data, real-world data to generate evidence about healthcare interventions, AI-assisted decision-making in healthcare, public-private partnerships in healthcare and research, and cross-sectoral big data.

The paper charts both the interpersonal connections between historical anarchist figures and the beat poets as well as the philosophical similarities between them. Almost all the beat poets were anarchists, though their politics was secondary to their attempts to transform consciousness. Among the anarchists, the romantic socialist Gustav Landauer, who was especially popular in post-war American anarchist circles, came closest to the political perspective of the beat poets. Like the beats, Landauer was a poet, a pacifist, an anarchist, a communitarian, (...) a romantic, and a mystic. In northern California, the circle of anarchists surrounding Kenneth Rexroth provided support and inspiration to the early beat movement. In New York, the beats had an affinity with anarchists such as David Thoreau Wieck and the publication "Why?" (later "Resistance"), as well as Dwight Macdonald's "politics" and Holley Cantine's "Retort". (shrink)

This analytical study explores the nature of scientific progress connected to current philosophical definitions and the role of institutional governance in promoting this progress. This paper examines how public and private initiatives intersect to create a wartime level of scientific progress during peacetime, as promoted in detail by Vannevar Bush, Director of the Office of Scientific Research and Development (OSRD) from 1941-47. This study suggests that the public benefit from the war footing approach to scientific progress should outweigh the losses (...) to the public good that accumulate due to wartime restrictions on scientific discourse during times of peace. The interaction and dependence of scientific progress on military development, public health and public needs in general, the tax code and the patent system form the foundation of Bush’s program for sustaining wartime levels of scientific progress during peacetime. This study references the COVID-19 period and the solutions that were applied to emergent public needs through scientific programs. Justice of the United States (U.S.) Supreme Court Neil Gorsuch noted in May 2023 that “…we may have experienced the greatest intrusions on civil liberties in the peacetime history of this country.” This study proposes that the dilution of scientific truth in public policy is the result of a collective institutional mindset among scientists. This mindset endorses public programs that provide society with a wartime risk response in peacetime. In this study, from an epistemological standpoint and considering the work of other researchers in this field, these developments in scientific progress will be analyzed. (shrink)

Mathematicians often describe the importance of well-developed intuition to productive research and successful learning. But neither education researchers nor philosophers interested in epistemic dimensions of mathematical practice have yet given the topic the sustained attention it deserves. The trouble is partly that intuition in the relevant sense lacks a usefully clear characterization, so we begin by offering one: mature intuition, we say, is the capacity for fast, fluent, reliable and insightful inference with respect to some subject matter. We illustrate the (...) role of mature intuition in mathematical practice with an assortment of examples, including data from a sequence of clinical interviews in which a student improves upon initially misleading covariational intuitions. Finally, we show how the study of intuition can yield insights for philosophers and education theorists. First, it contributes to a longstanding debate in epistemology by undermining epistemicism, the view that an agent’s degree of objectual understanding is determined exclusively by their knowledge, beliefs and credences. We argue on the contrary that intuition can contribute directly and independently to understanding. Second, we identify potential pedagogical avenues towards the development of mature intuition, highlighting strategies including adding imagery, developing associations, establishing confidence and generalizing concepts.

This article, which appeared in the Library of Living Philosophers series, is a thought experiment that imagines Danto’s analytical framework reaching well beyond what he had called the “drab” state of philosophy in the early 2000s. It describes, in minimalist terms, what he saw as the fundamental project of all philosophy -- regardless of the specific theoretical content any particular philosopher might put forth. It discusses his central (and still underdeveloped) notion of representation, and his quasi-Hegelian view of how art (...) theory has been altered by its own recently emerging self-consciousness. It draws out the implications of his Argument from Intelligibility, which informs Danto’s interest in human self-consciousness, in autonomy, and (somewhat speculatively) in “spirit.”. (shrink)

Majority cycling and related social choice paradoxes are often thought to threaten the meaningfulness of democracy. But deliberation can prevent majority cycles – not by inducing unanimity, which is unrealistic, but by bringing preferences closer to single-peakedness. We present the first empirical test of this hypothesis, using data from Deliberative Polls. Comparing preferences before and after deliberation, we find increases in proximity to single-peakedness. The increases are greater for lower versus higher salience issues and for individuals who seem to have (...) deliberated more versus less effectively. They are not merely a byproduct of increased substantive agreement. Our results both refine and support the idea that deliberation, by increasing proximity to single-peakedness, provides an escape from the problem of majority cycling. (shrink)
