Gender, race, and sexuality are not just identities; they are also systems of social organization – i.e., systems of privilege and oppression. This article addresses two main ways privilege and oppression (e.g., racism, misogyny, heteronormativity) are relevant topics in and for philosophical aesthetics: (i) the role of the aesthetic in privilege and oppression, and (ii) the role of philosophical aesthetics, as a discipline and a body of texts, in constructing and naturalizing relations of privilege and oppression (i.e., white heteropatriarchy). The (...) first part addresses how systems of privilege and oppression use the aesthetic. I will discuss various ways race, gender, and sexuality, as both embodied identities and broader social institutions, work with and through “the aesthetic”. The second part addresses racism and (hetero) sexism in the discipline of aesthetics. Both in its history and its present practice aesthetics’apparent neutrality on questions of privilege and oppression is actually evidence of its investment in systems of privilege and oppression.

“Political epistemology” has recently emerged as an area of analytic epistemology. While it may not be an entirely new area, and its precise boundaries are up for negotiation, recent political events in the UK (e.g. Brexit) and the US (e.g. the election of Donald Trump) played a key role in its rise to prominence within contemporary analytic epistemology. Further, political epistemology is an inter-disciplinary field, drawing on relevant work in political science, political psychology, and science communication that is often equally (...) focused on the UK and US. Political epistemology is therefore parochial, though it is the kind of parochialism that is not always conscious of itself as parochial. In this talk I adopt a critical stance towards parochialism in political epistemology. But my aim is not just to point out the mistakes that can result from a parochial concern with political events in one’s own country. I suggest that we can view political epistemology as interested in certain fundamental problems and tensions, which political epistemologists may then seek to identify and address within the political context in which they are working.

Feminist, critical race, and postcolonial theories have established that social identities such as race and gender are mutually constitutive—i.e., that they “intersect.” I argue that “cultural appropriation” is never merely the appropriation of culture, but also of gender, sexuality, class, etc. For example, “white hipness” is the appropriation of stereotypical black masculinity by white males. Looking at recent videos from black male hip-hop artists, I develop an account of “postmillennial black hipness.” The inverse of white hipness, this practice involves the (...) appropriation, by black men, of stereotypical white gay masculinity and/or non-American, non-white femininity. I also argue that Shephard Fairey’s recent images of (mainly militant) non-Western women of color can be read as a new form of white hipness that revises the traditional logic in two ways: (1) by appropriating non-white femininity rather than masculinity, and (2) by adopting the practice of postmillennial black hipness itself.

Pronouns often convey information about a person’s social identity (e.g., gender). Consequently, pronouns have become a focal point in academic and public debates about whether pronouns should be changed to be more inclusive, such as for people whose identities do not fit current pronoun conventions (e.g., gender non-binary individuals). Here, we make an empirical contribution to these debates by investigating which social identities lay speakers think that pronouns should encode and why. Across four studies, participants were asked to evaluate different (...) types of real and hypothetical pronouns, including binary gender pronouns, race pronouns, and identity-neutral pronouns. We sampled participants from two languages with different pronoun systems: English (N = 1,120) and Turkish (N = 260). English pronouns commonly denote binary gender (e.g., he for men), whereas Turkish pronouns are identity-neutral (e.g., o for anyone). Participants’ reasoning about pronouns reflected both a familiarity preference (i.e., participants preferred the pronoun type used in their language) and—critically—participants’ social ideologies. In both language contexts, participants’ ideological beliefs that social groups are inherently distinct (essentialism) and should be hierarchal (social dominance orientation) predicted relatively greater endorsement of binary gender pronouns and race pronouns. A preregistered experimental study with an English-speaking sample showed that the relationship between ideology and pronoun endorsement is causal: Ideologies shape attitudes toward pronouns. Together, the present research contributes to linguistic and psychological theories concerning how people reason about language and informs policy-relevant questions about whether and how to implement language changes for social purposes.

Working beyond the inclination to inaugurate alternative theoretical traditions alongside canonical sociology, this article demonstrates the value of recovering latent gender theory from within classic concepts—in this case, Weber’s “charisma.” Close readings of Weber reveal, (a) tools for theorizing extraordinary, non-masculinist agency, and, (b) clues that account for the conventional wisdom (popular and scholastic) that charisma is “not for women.” While contemporary movements may be tempted to eschew charismatic leadership per se because of legacies of dominance by men, there is (...) value in Weber’s formulation, which anticipated the performative turn in social theory that would destabilize biologistic gender ontologies. Value in this exchange also flows back to Weber: by confronting his intermittent tendency to describe charisma in terms that we now recognize as “customs of manly power,” we reveal heretofore unseen imperfections (i.e., traditionalist modes of legitimation) in his ideal-type. This engagement thus demonstrates an empowering mutuality between contemporary gender theory and “the classics.” The article ends by theorising the nexus of gender and charisma in the case of Trump, pointing to possibilities for vitiating Donald Trump’s charisma, as well as for anti-Trumpian charisma.

In this article, I examine the moral dimensions of gender affirmation. I argue that the moral value of gender affirmation is rooted in what Iris Murdoch called loving attention. Loving attention is central to the moral value of gender affirmation because such affirmation is otherwise too fragile or insincere to have such value. Moral reasons to engage in acts that gender affirm derive from the commitment to give and express loving attention to trans people as a way of challenging their (...) marginalization. In the latter part of the paper, I will discuss how my arguments bear on recent arguments by Robin Dembroff and Daniel Wodak (2018) on the use of gender-neutral language. They argue that we have a duty not to use gender-specific pronouns for anyone. Their conclusion turns, in part, on a rejection of gender affirmation as a moral duty. The value of gender affirmation, rooted in our moral perception of trans people, should make us skeptical of this conclusion, in favor of a more nuanced and pluralistic approach to the ethics of gendering.

I. EXECUTIVE SUMMARY The MRCT Center Post-trial Responsibilities: Continued Access to an Investigational Medicine Framework outlines a case-based, principled, stakeholder approach to evaluate and guide ethical responsibilities to provide continued access to an investigational medicine at the conclusion of a patient’s participation in a clinical trial. The Post-trial Responsibilities (PTR) Framework includes this Guidance Document as well as the accompanying Toolkit. A 41-member international multi-stakeholder Workgroup convened by the Multi-Regional Clinical Trials Center of Brigham and Women’s Hospital and Harvard University (...) (MRCT Center) developed this Guidance and Toolkit. Project Motivation A number of international organizations have discussed the responsibilities stakeholders have to provide continued access to investigational medicines. The World Medical Association, for example, addressed post-trial access to medicines in Paragraph 34 of the Declaration of Helsinki (WMA, 2013): “In advance of a clinical trial, sponsors, researchers and host country governments should make provisions for post-trial access for all participants who still need an intervention identified as beneficial in the trial. This information must also be disclosed to participants during the informed consent process.” This paragraph and other international guidance documents converge on several consensus points: • Post-trial access (hereafter referred to as “continued access” in this Framework [for terminology clarification – see definitions]) is the responsibility of sponsors, researchers, and host country governments; • The plan for continued access should be determined before the trial begins, and before any individual gives their informed consent; • The protocol should delineate continued access plans; and • The plan should be transparent to potential participants and explained during the informed consent process. -/- However, there is no guidance on how to fulfill these responsibilities (i.e., linking specific responsibilities with specific stakeholders, conditions, and duration). To fill this gap, the MRCT Center convened a working group in September of 2014 to develop a framework to guide stakeholders with identified responsibilities. This resultant Framework sets forth applicable principles, approaches, recommendations and ethical rationales for PTR regarding continued access to investigational medicines for research participants.

Un viaggio nell'opera filosofica, narratologica e poetologica di Ingeborg Bachmann che include i radiodrammi e i saggi radiofonici.

The present piece, first presented on 19 November 2016 at the Centre Léon Robin (CNRS-Univ. Paris-Sorbonne-ENS Ulm) as part of the“Présocratiques” Seminar, is an investigation of the relationship between Empedocles and Freud. The analysis is divided into three parts: the first section examines the nature of Freud’s engagement with Empedocles; next, consideration is given to the similarities between their doctrines, based on the extant fragments of the Empedoclean corpus; finally, I offer a series of observations about Empedocles’ poetic style, (...) which shares strong affinities with the spoken word in a manner typical of the oral tradition and is freighted with corporeal and emotional significance. It is here that we see the emergence of one of the key concepts of psychoanalysis: the relationship between logos and alogon, between that which can be rationally analysed and that which can be intuited but which eludes the domain of logos.

DESENVOLVIMENTO EMBRIONÁRIO E DIFERENCIAÇÃO SEXUAL -/- E. I. C. da Silva Departamento de Agropecuária – IFPE Campus Belo Jardim Departamento de Zootecnia – UFRPE sede -/- 1.1 INTRODUÇÃO O sexo foi definido como a soma das diferenças morfológicas, fisiológicas e psicológicas que distinguem o macho da fêmea permitindo a reprodução sexual e assegurando a continuidade das espécies. Os processos de diferenciação sexual são realizados durante o desenvolvimento embrionário, onde ocorre a proliferação, diferenciação e maturação das células germinativas e primordiais, precursoras (...) de ovócitos e espermatozoides em fêmeas e machos, respectivamente. Assim, os embriões machos e fêmeas iniciam o seu desenvolvimento de forma semelhante, de modo que em ambos os sexos se estabelecem em estruturas idênticas a partir das quais se formarão os órgãos reprodutores correspondentes a cada sexo. O conhecimento da origem e do desenvolvimento do aparelho genital é indispensável para entender sua função e as alterações que produzem infertilidade ou esterilidade. 1.2 DETERMINAÇÃO DO SEXO CROMOSSÔMICO Nos mamíferos, o sexo cromossômico é determinado no momento da fertilização, quando um óvulo, que contém um cromossomo X, é fecundado por um espermatozoide portador de um cromossomo X ou um cromossomo Y. No primeiro caso, o complemento cromossômico seria XX, o que originaria uma fêmea (sexo homogamético), e no segundo daria como resultado um macho com a fórmula cromossômica XY (sexo heterogâmico). 1.3 A GÔNADA INDIFERENCIADA A primeira manifestação das gônadas se aprecia no embrião em forma de um par de eminências longitudinais chamadas cristas ou dobras gonodais, situadas em ambos os lados da linha média entre os mesonefros (rins em desenvolvimento) e do mesentério dorsal. Nos embriões dos mamíferos, as células germinativas primordiais (CGP) manifestam-se em estágios precoces do desenvolvimento, podendo ser detectadas pela primeira vez na metade da gastrulação. As CGP são células grandes, de citoplasma claro e núcleo grande e redondo, localizadas na parede do saco vitelino, perto do alantoide. Essas células possuem grande capacidade de proliferação e vão migrar desde o endoderma do intestino e o epitélio do saco vitelino, através do mesentério, até as cristas gonodais. Isso ocorre por volta do 26° dia da gestação no bovino. Sua migração realiza-se graças aos movimentos de translocação passiva e deslocamento ameboide ativo. Desconhece-se o mecanismo pelo qual estas células são dirigidas para as cristas gonodais, porém foram estudadas algumas moléculas que se expressam durante sua migração e que poderiam desempenhar um papel importante na diferenciação deste tipo celular. A fosfatase alcalina é uma enzima que tem sido usada como marcador de CGP para determinar a sua origem e migração. Num estudo recente, foi inserido um marcador fluorescente que se exprime unicamente nas células germinativas primordiais de embriões transgênicos, e utilizando este marcador e a fosfatase alcalina determinou-se a origem e o padrão de migração destas células. O primeiro sinal de diferenciação das células germinativas primordiais é a expressão de fosfatase alcalina, e esta apareceu pela primeira vez na parte mais posterior da linha primitiva. No sétimo dia de desenvolvimento no embrião do camundongo, o endoderma visceral (AF+) é substituído pelo endoderma definitivo (AF-) originado na parte anterior da linha primitiva. O fator de transcrição Oct-4 é expresso nas CGP de ambos os sexos, pelo que acredita-se estar envolvido na mantença a totipotêncialidade das células. O receptor tirosina quinase, cujo ligante é o fator de Steel, é outra das moléculas que expressam as CGP. Tem sido demonstrado que este receptor possui um papel muito importante na sobrevivência deste tipo celular. Existem outros fatores que promovem a sobrevivência e/ou proliferação de CGP in vitro. Em experiências realizadas com o fator de transformação beta I (TGFβ-I), observou-se que este tem um efeito negativo sobre a proliferação das CGP. Outra atividade que tem sido postulada a este fator é o de um agente quimioatraente que possivelmente possa direcionar a migração destas células para a gônada. a) Um formado pelas células germinativas primordiais (precursoras dos gametas masculinos ou femininos), rodeadas de células somáticas das quais posteriormente se derivarão as células de Sertoli no macho e as células da granulosa na fêmea. b) O tecido que formará o estroma da gônada: tecido conjuntivo, vasos sanguíneos e as células intersticiais com atividade esteroidogênica (células de Leydig no testículo e a teca interna do ovário). As células somáticas do primórdio gonodal originam-se do mesoderma. Inicialmente são de três tipos: mesenquimáticas, mesoteliais e endoteliais. As células mesenquimáticas e mesoteliais iniciam grande atividade proliferativa ao chegar as CGP. Observa-se então uma condensação de células de origem mesotelial e mesenquimatoso que forma um agregado compacto denominado "blastema gonodal". A partir deste primórdio embrionário, diferenciam-se dois tecidos gonodais: os cordões sexuais e o estroma. Os cordões sexuais são arranjos epiteliais que se encontram delimitados por uma folha basal, e dentro deles encontramos as CGP. Por sua vez, no estroma encontram-se células do tipo mesenquimático e vasos sanguíneos. Neste momento, as gônadas são indiferenciadas e bipotencialmente sexuais, sendo impossível diferenciar, morfologicamente, uma gônada masculina de uma feminina, mas no caso dos machos genéticos já existe uma diferenciação da gônada a nível molecular. Nesta fase já se encontram presentes as estruturas das quais se desenvolvem os dutos mesonéfricos ou de Wolff precursores do aparelho genital masculino e os dutos paramesonéfricos ou de Müller que darão origem ao aparelho reprodutor feminino. Há uma série de fatores envolvidos no desenvolvimento precoce da gônada, entre os quais o fator esteroidogênico I (SFI: Steroidogenic fator l), que é um membro da subfamília de receptores nucleares, receptores órfãos. Este fator de transcrição tem um local de ligação ao DNA composto por dois dedos-de-Zinc. O SFI foi identificado como um ativador de genes envolvidos na biossíntese de esteroides em diferentes células. O SFI está presente durante o desenvolvimento embrionário em regiões associadas com funções endócrinas como gônadas, adrenais, pituitárias e hipotálamos. Os animais homozigotos para o gene SFI defeituoso, necessitam de gônadas e adrenais e têm a função gonadotrófica alterada. Os ratos sem SFI carecem de gonadotrofos e têm um desenvolvimento anormal do núcleo ventro-medial do hipotálamo; em particular as gônadas deixam de se desenvolver entre os dias 11 a 15 e degeneram-se por apoptose. No entanto, a crista genital forma-se e é colonizada pelas células germinativas, o que indica que estas continuam a receber o sinal adequado para a sua migração. Portanto, o SFI não está envolvido no desenvolvimento precoce da gônada e do sistema urogenital, mas parece estar envolvido na manutenção do crescimento das células somáticas presentes na gônada indiferenciada. O gene associado ao tumor de Wilms (WTI: Wilm's tumor Associated) está envolvido no desenvolvimento da gônada e do rim. Durante o desenvolvimento embrionário, WTI se expressa em todo o mesoderma intermediário e posteriormente na gônada indiferenciada, bem como no rim em formação. WTI regula o sinal indutivo do mesênquima para o epitélio celômico dos mesonefros. Se este for o caso, então WTI é responsável pelo crescimento da crista genital ao dirigir a entrada do epitélio celômico. Dado que estas células darão origem às células de Sertoli, a carência de WTI pode causar o desenvolvimento de embriões XY como fêmeas simplesmente porque não se formam as células de Sertoli. Em geral, todos os genes importantes na diferenciação do mesoderma intermediário e do sistema urogenital intervêm no desenvolvimento da gônada precoce. 1.4 DIFERENCIAÇÃO GONODAL O desenvolvimento das gônadas e ductos genitais descritos até o momento, é o mesmo para ambos os sexos. Igualmente, os genes descritos, que estão envolvidos no desenvolvimento das gônadas, ductos genitais e migração das células germinativas, afetam igualmente os embriões com genótipo XX ou XY. A gônada primitiva consiste anatomicamente de uma medula (interna) e uma crosta (externa), e de acordo com o local onde ocorre a colonização das células germinativas, diferenciara em testículo ou um ovário, respectivamente. Nos mamíferos, a primeira manifestação estrutural de diferenciação sexual é detectada na gônada dos machos, onde as células germinativas estão localizadas na medula. A diferenciação do testículo inicia-se quando os cordões sexuais se separam do epitélio celômico como consequência dos arranjos produzidos por uma invasão do mesênquima e vasos sanguíneos que provoca a compactação dos cordões, agora denominados cordões testiculares. As células que rodeiam os cordões se achatam e formam as células mioides, que são responsáveis pela formação das membranas basais. As células do epitélio interno, ou seja, as células de Sertoli, têm duas funções principais: o suporte das CGP e a síntese da hormona antimulleriana, responsável pela regressão dos ductos de Müller e secretada durante o período de diferenciação sexual. As células do estroma que rodeiam os cordões testiculares diferenciam-se para formar vários tipos de células: células mioides, fibroblastos, endotélio e células de Leydig, que são as mais importantes pela sua atividade endócrina. Posteriormente, os cordões testiculares dão origem aos túbulos seminíferos, que contêm o epitélio que produzirá os espermatozoides ao chegar à puberdade. Na fêmea, durante os estágios iniciais de diferenciação gonodal, não se observam mudanças em relação à gônada indiferenciada, só pode-se observar um certo crescimento devido à proliferação de células somáticas e germinativas. As células germinativas iniciam um período de proliferação, que termina com o início da meiose. Iniciada a meiose, dá-se o processo de foliculogênese; neste momento os cordões epiteliais se fragmentam, de tal maneira que cada ovócito fica rodeado de células epiteliais cobertas por uma folha basal fina (figura 1). Para que a gônada primitiva se desenvolva em testículo é indispensável a presença do cromossoma Y, independentemente do número de cromossomas X que contenha o genoma de um indivíduo. O gene determinante do testículo encontra-se localizado no cromossoma Y, denominado sry em ratos e SRY em humanos. O gene sry se expressa durante o desenvolvimento embrionário na crista genital de embriões de camundongos. A expressão é detectável no dia 10,5, pouco depois do aparecimento das cristas genitais, atinge o seu máximo durante o dia 11,5 e mantém-se até pouco depois de ocorrerem os primeiros sinais morfológicos de diferenciação testicular no dia 12,5. Este padrão de expressão é compatível com a teoria de que sry atua induzindo a ativação dos genes (figura 2) que conduzem ao desenvolvimento testicular, sem que exista a necessidade da expressão contínua de sry para manter a diferenciação do testículo após o dia 12,5. Como mencionado anteriormente, a gônada primitiva é composta por vários tipos de células. No entanto, as células germinativas primordiais não são o local de expressão do sry, já que os embriões que necessitam de células germinativas mantêm a expressão de sry e desenvolvem o sexo gonodal normalmente. As células somáticas na gônada em desenvolvimento incluem também as células de suporte. Sabe-se que é nestas células que o sry é expresso para que se diferenciem em células de Sertoli, e a expressão transitória de sry indica que deve ativar a outros genes para a manutenção das células de Sertoli. Uma vez diferenciadas as células de Sertoli, elas se encarregarão da diferenciação do resto das células na gônada. -/- Figura 1: Representação da diferenciação dos órgãos genitais internos. Adaptado de BRONSON, 1989. Figura 2: Cascada de genes envolvidos na diferenciação sexual, adaptado de KOOPMAN, 1999. O fator sry é necessário para a diferenciação do testículo. Embora não se conheçam os genes que provavelmente regulam esse gene, estudos realizados em camundongos demonstram que este gene parece coordenar-se com certos genes autossômicos. Entre estes genes autossômicos, o sox9, que é produzido pelas células de Sertoli uma vez que são estimuladas por sry, de modo que sox9 é um dos genes relacionados estruturalmente com sry. O Sox9 funciona como um fator de transcrição, mas não se sabe se a proteína tem qualquer outra função estrutural; este gene exprime-se abundantemente nos condrócitos e está relacionado com defeitos do aparelho ósseo chamados displasia campomélica. Curiosamente, os pacientes XY com esta condição sofrem frequentemente de reversão do sexo. O Sox9 é um dos poucos genes, além do SRY, do qual as mutações demonstraram interferir com a determinação sexual masculina. No entanto, apenas 75% dos pacientes com anomalias esqueléticas de tipo displasia campomélica têm reversão sexual e não foram encontrados casos de reversão sexual devido a um defeito de Sox9 que não seja acompanhado de defeitos esqueléticos. Isso indica que o Sox9 é apenas um membro da rede de genes que são ativados para determinar a diferenciação sexual, enquanto a rota que rege a condrogênese é mais sensível a perturbações deste. O momento em que se detecta a expressão do gene Sox9 (11dpc em ratos) coincide com a máxima expressão de sry, o que poderia indicar a possibilidade de que sry regule positivamente a Sox9. De fato, na região do promotor de Sox9 há um local de união ao que potencialmente se pode unir o sry. A expressão de Sox9 durante a diferenciação sexual sugere um papel abaixo de sry na diferenciação das células de Sertoli. O cromossoma X também é importante na diferenciação gonodal. O gene DAX-I foi isolado do lócus DSS (Dosage sensitive sex reversal) do cromossoma X. DAX-I é parte da cascata de determinação sexual, mas não é necessário para a formação do testículo. DAX-I é um membro dos receptores nucleares conhecidos como receptores órfãos. Este gene demonstrou ser um poderoso repressor da transcrição de SFI e de vários genes. Os padrões de expressão de DAX-I são complementares daqueles de SFI, ambos expressos nas cristas genitais. Em resumo, dada a evidência exposta, desenvolveu-se a hipótese de que DAX-I é um antagonista de sry; esse antagonismo é dependente dos níveis relativos de DAX-I e sry e de um limiar que varia de espécie para espécie. A DAX-I foi classificada como o gene antitestículo. Na fêmea (cariótipo XX) é importante que ocorra a inativação de um dos cromossomas sexuais X para que se mantenha o equilíbrio genético ao igualar o conteúdo de DNA dos cromossomas. Esse cromossoma inativado constitui o chamado corpúsculo de Barr. No entanto, para que a meiose se realize, é necessário dos dois cromossomas X ativos nos ovócitos para assegurar a diferenciação ovárica e a fertilidade. 1.5 DIFERENCIAÇÃO DOS DUCTOS SEXUAIS O embrião possui, além das gônadas indiferenciadas, dois sistemas de ductos: os de potencialidade masculina denominam-se ductos de Wolff ou mesonéfricos, e os de potencialidade feminina se chamam ductos de Müller ou paramesonéfricos (figura 1). Se a diferenciação gonodal levou à formação de um testículo, a partir do ducto mesonéfrico ou de Wolff se desenvolverão os ductos eferentes, o epidídimo, os ductos deferentes e as vesículas seminais. As hormonas importantes no desenvolvimento do aparelho genital masculino são a testosterona, produzida pelas células de Leydig, e sua forma 5α reduzida, a 5α di-hidrotestosterona. Acredita-se que a testosterona é responsável pela virilização dos ductos de Wolff, e a di-hidrotestosterona dos órgãos genitais externos. No macho, os canais de Müller atrofiam-se devido à ação de uma hormona fetal de origem testicular denominada hormona inibidora das estruturas de Müller (HIM) ou hormona antimulleriana. Este processo começa assim que os cordões espermáticos se formam e se diferenciam as células de Sertoli. A existência de HIM foi proposta baseada em estudos realizados em bezerras freemartin, devido à existência de uma hormona responsável pela atresia dos ductos de Müller que na fêmea dá origem ao útero e aos ovidutos. Essa hormona provoca a involução do aparelho genital do bovino nas gestações gemelares nas quais os produtos de diferente sexo têm comunicação sanguínea por ter ocorrido a anastomose dos vasos de ambas as placentas (figura 3). A HIM é uma glicoproteína pertencente à subfamília de TGFβ, é expressa pelas células que darão origem às células de Sertoli e é um dos primeiros marcadores de diferenciação nestas células. A HIM é secretada na vida adulta pelas células de Sertoli no testículo e por células da granulosa no ovário. No rato a HIM é expressa-se no 12° dia em um teste padrão que segue muito de perto o aumento na expressão de sry. No macho, esta secreção de HIM continua durante a vida fetal e adulta, contudo os níveis de HIM declinam na puberdade devido a um aumento na secreção de testosterona. Vários fatores intervêm na regulação do gene de HIM, incluindo os acima descritos SFI e Sox9. O gene HIM contém segmentos de DNA que são conservados em várias espécies de vertebrados. Existe um nexo de ligação para SFI, que ativa a transcrição de HIM. A mutação no local de ligação de SFI resulta em reversão do sexo em indivíduos XY incluindo genitais femininos normais, presença de um útero formado enfatizando a importância de SFI na determinação sexual e na expressão de HIM. Embora SFI seja um bom candidato como regulador de HIM, é expresso em outras células, como as de Leydig e adrenais, que não expressam HIM. Em contrapartida, Sox9 é expresso unicamente nas células de Sertoli que são as produtoras de HIM. O gene HIM também tem um nexo de ligação para Sox9. Além disso, Sox9 pode atuar sinergicamente com SFI para promover a secreção de HIM. Ao contrário destes dois fatores de transcrição, DAX-I antagoniza a ação de Sox9 e provavelmente SFI sobre o promotor de HIM. Assim, para que as células de Sertoli secretem HIM, a transcrição de DAX-I deve diminuir. Figura 3: Representação da diferenciação dos órgãos genitais externos. Adaptado de BRONSON, 1989. Os ductos de Wolff tornam-se o sistema de ejaculação do macho. A porção mais próxima dos testículos dá origem ao epidídimo, a parte central ao ducto deferente e a porção mais distal às vesículas seminais. A próstata e a parte membranosa da uretra do macho desenvolvem-se a partir da porção pélvica do seio urogenital. A virilização e diferenciação dos ductos de Wolff dependem da produção de testosterona pelo testículo. Quanto aos órgãos genitais externos do macho, o tubérculo genital é ampliado e as dobras uretrais se fundem para formar a uretra peniana. A fusão das dobras uretrais aproxima os tubérculos genitais para formar o escroto (figura 4). Figura 4: Diferenciação do aparelho genital da fêmea e do macho. Adaptado de KOOPMAN, 1989. A diferenciação dos órgãos genitais da fêmea ocorre de forma passiva, já que a ausência de testículos e por isso da hormona inibidora dos ductos de Müller (HIM), assim como dos andrógenos virilizantes, favorece o desenvolvimento dos ductos de Müller, enquanto os de Wolff sofrem atrofia. A porção cefálica dos ductos de Müller dá origem aos ovidutos, que na sua terminação caudal se fundem com o útero. O contato dos ductos de Müller com o seio urogenital induz uma intensa proliferação celular que resulta na formação da área uterovaginal localizado entre o seio urogenital e os ductos de Müller. As células do prato uterovaginal proliferam e aumentam a distância entre as duas estruturas criando o espaço que formará a vagina quando o prato é canalizado e forma um lúmen. Em contraste com o que ocorre no macho, na fêmea a maior parte do seio urogenital se mantém exposta na superfície da abertura onde desembocam a vagina e a uretra. O tubérculo urogenital da fêmea tem um crescimento limitado e forma o clitóris. A sequência de passos da diferenciação sexual do aparelho genital é resumida na tabela 1.

Assim, da mesma maneira que a gônada e os ductos sexuais se desenvolvem para o tipo feminino ou masculino, propôs-se que o cérebro pode ser "masculinizado" ou permanecer "Feminizado". A diferenciação do hipotálamo vai depender do ambiente esteroidal do neonato e ocorre na fase perinatal. Estes eventos serão de grande transcendência na vida reprodutiva do indivíduo. Tanto a fêmea como o macho nascem com a capacidade de secreção de gonadotropinas de acordo com um padrão cíclico; contudo, no macho, a exposição do hipotálamo à ação dos andrógenos testiculares durante os primeiros dias da vida extrauterina provoca a masculinização, com o qual o hipotálamo do macho é programado para que a secreção de gonadotropinas se realize a um ritmo relativamente constante por parte da hipófise (secreção tônica). Na fêmea, tanto a secreção tônica como a cíclica se conservam. No entanto, observou-se que a injeção de testosterona ou o transplante de testículo na rata fêmea durante os primeiros dias de vida, suprime a sua futura atividade estral (secreção cíclica). Por outro lado, se os ovários forem transplantados para o rato macho normal castrado na idade adulta, o animal não desenvolve qualquer atividade cíclica, mas se os machos transplantados forem castrados ao nascer, o ovário é capaz de efetuar mudanças cíclicas e ovulações. Isto foi demonstrado em roedores, mas não em animais domésticos ou na espécie humana. Portanto, o padrão de secreção de gonadotropinas, seja cíclico ou tônico, não depende da hipófise, mas do hipotálamo e sua correta diferenciação. 1.7 CONCLUSÕES A maioria dos conhecimentos no campo da biologia do desenvolvimento e, muito especificamente, dos processos de diferenciação sexual têm sido originados de estudos relacionados com desordens congênitas, que na sua maioria devem-se a defeitos de genes específicos. A análise detalhada destas desordens permitiu entender alguns mecanismos endócrinos, moleculares e genéticos envolvidos na diferenciação sexual. A identificação do gene sry como determinante do testículo foi uma contribuição crucial e abriu as portas à compreensão dos mecanismos moleculares e celulares relacionados com o desenvolvimento do testículo. Se este gene não estiver presente, é criado um programa genético alternativo para levar a cabo a diferenciação gonodal para o ovário. Finalmente, devemos ter presente que é necessária uma correlação entre mudanças morfológicas e expressão de genes durante o desenvolvimento para entender os mecanismos relacionados com a diferenciação. -/- Apoio -/- Realização -/- REFERÊNCIAS BIBLIOGRÁFICAS ANDERSON, Robert et al.

Nei dintorni di Paul Celan e Ingeborg Bachmann.

Poesia come cammino verso la casa che non c'è, perché è sempre con noi.

Robin McKenna’s excellent Non-Ideal Epistemology is, among other things, a testament to restraint. McKenna does not want to unnecessarily inflame tensions between ideal and non-ideal theorists in epistemology. Often ideal and non-ideal projects are aimed at different target domains and not in tension with one another (though not always; e.g. McKenna 2023, ch. 6, especially pp. 112-21). In this commentary, I will have much less tact. I sketch a route by which the non-ideal epistemologist might become more belligerent towards (...) their ideal counterparts. I do this by focusing on an area that McKenna mostly sets aside: non-ideal individual epistemology. (shrink)

Abstract - Evolutionary, ecological and ethical studies are, at the same time, specific scientific disciplines and, from an historical point of view, structurally linked domains of research. In a context of environmental crisis, the need is increasingly emerging for a connecting epistemological framework able to express a common or convergent tendency of thought and practice aimed at building, among other things, an environmental policy management respectful of the planet’s biodiversity and its evolutionary potential. -/- Evolutionary biology, ecology and ethics: at (...) first glance, three different objects of research, three different worldviews and three different scientific communities. In reality, there are both structural and historical links between these disciplines. First, some topics are obviously common across the board. Second, the emerging need for environmental policy management has gradually but radically changed the relationship between these disciplines. Over the last decades in particular, there has emerged a need for an interconnecting meta-paradigm that integrates more strictly evolutionary studies, biodiversity studies and the ethical frameworks that are most appropriate for allowing a lasting co-evolution between natural and social systems. Today such a need is more than a mere luxury, it is an epistemological and practical necessity. -/- In short, the authors of this volume address some of the foundational themes that interconnect evolutionary studies, ecology and ethics. Here they have chosen to analyze a topic using one of these specific disciplines as a kind of epistemological platform with specific links to topics from one or both of the remaining disciplines. Michael Ruse’s chapter, for instance, elucidates some of the structural links between Darwinismand ethics. Ruse analyzes the Evolutionism vs. Creationism debate, emphasizing the risks run by scientists when they ideologize the scientific content of their studies. In the case of the contributions of Jean Gayon and Jean-Marc Drouin, which respectively deal with the disciplines of evolutionary biology and ecology, some central connections have been developed between these two disciplines, while reserving the option to consider in detail their topic in order to discover essential features ormeanings. Gayon analyzes the multilayered meanings of “chance” in evolutionary studies and the methodological implications that accompany such disparatemeanings. Froma similar analytical perspective, Drouin’s contribution focuses on the identification and critical evaluation of the different conceptions of time in ecology. Chance and time, factors of evolution in species and ecological systems, play a very important function in both disciplines, and these chapters help to capture their polysemous structure and development. Bryan Norton’s chapter, on adaptive environmental management, is set within an epistemological context where the Darwinian paradigm, ecological knowledge and ethical frameworks meet to give rise to practical, conservationist policies. In his contribution, Patrick Blandin pleads for the necessity of an eco-evolutionary ethics capable of fully encompassing humanity’s responsibility in the future determination of the biosphere’s evolutionary paths. Our value systems must recognize the predominant place that humanity has taken in the evolutionary history of the planet, and integrate the ethical ramifications of scientific advances in evolutionary and ecological studies. The chapter by J. Baird Callicott introduces us to a metaphorical ecological reversion with direct consequences for our moral conduct. If ecology showed that ecosystems are not organisms, recognizing organisms as a kind of ecosystem could be the basis for a new post-modern ecological ethics that lays the foundation for a better moral integration of humans with the environment. The contributions of Robin Attfield and Tom Regan delve into some of the classical issues in environmental ethics, situating them within a broader ecological and evolutionary context. Attfield’s chapter tackles the confrontation between individualistic and ecologically holistic perspectives, their different approaches to the issue of intrinsic value, and their tangled relation to monism and pluralism. Regan’s contribution ponders the criteria that allow individual beings, human and non-human, to own moral rights, the role of the struggle for existence in the relationship between species, and the logical difficulties involved in attributing intrinsic value to collective entities (species, ecosystems). Catherine Larrère’s chapter discusses the opposition between two environmental and ethical worldviews with very different philosophical centers of gravity: nature and technology. These opposing perspectives have direct consequences not only for the perception of the problems at hand and for what entities are deemed morally significant, but also for the proposed solutions. -/- To set out some foundational events in the history of evolutionary biology, ecology and environmental ethics is a first necessary step towards a clarification of their major epistemological orientations. On the basis of this inevitably nonexhaustive history, it will be possible to better position the work of the different contributors, and to build a meta-paradigm, i.e. a connecting epistemological framework resulting from one common or convergent tendency of thought and practice shared by different disciplines.

In May 2010, philosophers, family and friends gathered at the University of Notre Dame to celebrate the career and retirement of Alvin Plantinga, widely recognized as one of the world's leading figures in metaphysics, epistemology, and the philosophy of religion. Plantinga has earned particular respect within the community of Christian philosophers for the pivotal role that he played in the recent renewal and development of philosophy of religion and philosophical theology. Each of the essays in this volume engages with some (...) particular aspect of Plantinga's views on metaphysics, epistemology, or philosophy of religion. Contributors include Michael Bergman, Ernest Sosa, Trenton Merricks, Richard Otte, Peter VanInwagen, Thomas P. Flint, Eleonore Stump, Dean Zimmerman and Nicholas Wolterstorff. The volume also includes responses to each essay by Bas van Fraassen, Stephen Wykstra, David VanderLaan, Robin Collins, Raymond VanArragon, E. J. Coffman, Thomas Crisp, and Donald Smith. (shrink)

When we were on the subway back from his lecture, I said to Robin: “I’m not sure there actually are any religious fictionalists.” We keep talking about them in papers and lectures, acting as if fictionalism in religion is a real possibility, but to be honest, I haven’t been able to spot one in the wild so far. The only potential candidate who comes to mind is Don Cupitt, who wrote things like: “I still pray and love God, even (...) though I fully acknowledge that no God actually exists.”[1] Perhaps this is as fictionalist as it gets. But then again, Cupitt never explicitly declared himself a fictionalist. Moreover, on other occasions he sounds more like an expressivist than a fictionalist, e.g. when he says: “The Christian doctrine of God just is Christian spirituality in coded form.”[2] So, if there are any actual fictionalists out there, please step forward.[1] Don Cupitt, After God: The Future of Religion, 85.[2] Don Cupitt, Taking leave of God, 14.

This article aims to provide an explication of a new conceptualisation of God's defeat of horrors (i.e., horror-defeat), and a successful solution to the Problem of Horrors—which we can term the ‘Reconciliation Account’. This specific conceptualisation will be formulated in light of the work of Marilyn McCord Adams, with an original extension of her work being made by utilising the work of Richard Swinburne and Robin Collins (amongst others), which, in combination, will provide us with a more robust solution (...) to the issue raised by horrors.

Our gender identity is our sense of ourselves as a woman, a man, as genderqueer, or as another gender. Our gender is the property we have of being a woman, being a man, being non-binary, or being another gender. What is the relationship between our gender identity and our gender? Recently, much work has been done on ameliorative accounts of the gender concepts that we should accept and on the metaphysics of gender properties. From this work 4 views of the (...) relationship between having gender identity G (e.g. having a female gender identity) and being a gender G (e.g. being a woman) have emerged. A first, the no connection view, says that gender identity and gender are entirely distinct; Sally Haslanger’s ameliorative account of gender, as well as Theodore Bach’s account of gender properties, are instances of this view. A second, the gender-identity-first view, says that all there is to our gender is our gender identity; this view is at least similar to views that Talia Bettcher and R.A. Briggs and B.R. George have argued for. A third, contextualist view, says that in some contexts and relative to certain standards, our gender identity determines our gender, and that in others it does not; Ásta and Robin Dembroff have proposed and defended views along these lines. A fourth view, the two gender properties view, says that there are two properties that can make it the case that one is gender G (in any context), one’s having gender identity G and one’s being socially classed as a G; Katharine Jenkins and Elizabeth Barnes have proposed views along these lines. This article explains these 4 different views and spells out their prospects, and the problems they face, as both ameliorative and as metaphysical views. (shrink)

Aristotle says that ὑπαρχειν has as many senses as ‘to be true’ (PrA. , A, 36, 48b2-9) and as many ways as there are different categories. (PrA., A, 37, 49a6-9) This may mean that for every ‘is’ there is a ὑπαρχειν. Τhe reason is that Aristotle uses ὑπαρχειν in converse direction of ‘is’. The equal statement of ‘A is B’ with ὑπαρχειν is ‘B ὑπαρχει to A.’ Allen Bāck points to the difference between the use of the verb with dative (...) case and its use with a subject alone in Greek language. When it is used with the dative, it retains its basic meaning, that is, ‘be already present’ or ‘exist really.’ ‘So to say that P belongs to S is to say that P exists in S, or, if you like, that P has its being in S.’ He believes that Aristotle uses this construction to insist that primary substances alone are the fundamental being and all other things only are ‘in’ substances. Thus, when the verb is used with the dative, it expresses dependent substance relation. But when it is used with a subject alone, e.g. in ‘S ὑπάρχει,’ it expresses that the subject really exists. (OI., 17a24 and 17b2) Thus, while it is the subject which is said to be the predicate, it is the predicate which ὑπάρχει to the subject. The formula of ‘τὸ Α ὑπάρχει τῷ Β’ is equivalent to ‘τὸ Β ἐστι Α.’ He uses the word for the predication of a category on substance (e.g. Met., α, 993b24-25; Met., Z, 1029a15-16; Cat., 5, 3b24-25), the predication of secondary substance on primary substance (e.g. Met., Z, 1038b21-23; Cat., 5, 2a14-19), the predication of primary substance on nothing else but itself (e.g. Met., Z, 1040b23-24), the belonging of a verb to the subject, the belonging of axioms to a single science (Met., 1005a22-23) , the belonging of PNC to all things that are (Met., IV, 3) , in the sense of really existing (Cael. 297b22, Met., 1041b4. Cf. B503, 125-126) or merely in the sense of the predication of a predicate on a subject (e.g. OI., I, 5, 17a22-24) and especially and much more repeatedly than anywhere else in his discussion of syllogism. (e.g. PrA., A, 36, 48a40-b2; PrA., B, 22, 67b28-30; PrA., A, 24a26-28) It is also used in some related senses like mere belonging (e.g. Met., A, 989a10-14; K, 1060a9-10) or to be there. (So., B, 5, 417b23-26) Some of its derived forms are also used by Aristotle. For example, ἐνυπαρχον in the sense of the thing that is ‘in’ something; (e.g. Met., A, 991a13-16; Met., Z, 1038b29-33 and 1039a3-5) ὑπερέχον in the sense of that which contains and ὑπερεχόμενον in the sense of that which is contained in something else. (e.g. Met., Δ, 1020b26-28) In a sense, the extent of the application of ὑπαρχειν is wider than ‘is’ since it is not restricted to the nominative form in which ‘is’ is used but is applicable to other cases as well: ‘For ‘That does not belong to this’ does not always mean that ‘This is not that’ but sometimes that ‘this is not of that’ or ‘for that.’ (PsA., A, 36, 48b28-33) Allen Bāck (B503, 124) points that in the Prior Analytics Aristotle uses ‘ὑπάρχει τῷ’ and ‘κατηγορεῖσθαι κατά’ interchangeably. (e.g. at 25b37-26a4) Referring to its converse construction in respect of μετέχει (if A belongs to B, then B participates in A) as a probable reason that it may have Platonist foundations. But the question is: why does Aristotle uses this construction (B belongs to A) instead of simply saying A is B? Alexander of Aphrodisias (Apr 54.21-29) wonders why Aristotle had to adhere to such artificial language, entirely unnatural for ordinary speakers of Greek. As Jonathan Barnes points out, all the three formulas of ‘τὸ Α ὑπάρχει τῷ Β,’ ‘τὸ Α κατηγορεῖται κατὰ τοῦ Β’ and ‘τὸ Α λέγεται κατὰ τοῦ Β’ are artificial in the sense that no Greek who wanted to say that pleasure was good would normally have expressed himself by way of any of them.’ Bāck thinks Aristotle may have used it ‘to stress the primacy of primary substances as the ultimate subjects.’ He also mentions the probability that it may be to emphasize that the terms are being coupled in predication without any existence condition, a suggestion he is not himself inclined with. Robin Smith notes for Aristotle that ‘belonging to’ construction is wider than ‘predicated of’ construction because it can be used for cases that cannot easily be treated as categorical sentences. While predication is restricted to cases in which the subject term is in the nominative case, belonging can indicate, as he quotes Mignucci (480-481), ‘any possible grammatical construction for a predicative relation’ .

In a recent essay, Donald Dripps advanced what he calls a “commodification theory” of rape, offered as an alternative to understanding rape in terms of lack of consent. Under the “commodification theory,” rape is understood as the expropriation of sexual services, i.e., obtaining sex through “illegitimate” means. One aim of Dripps's effort was to show the inadequacy of consent approaches to understanding rape. Robin West, while accepting Dripps's critique of consent theories, criticizes Dripps's commodification approach. In its place, West (...) suggests a more phenomenological approach. The author argues that neither Dripps nor West offers convincing critiques of consent-based theories; the alternatives they offer presuppose the vitality of a consent-based approach to understanding rape; and that both Dripps and West consistently conflate more general moral and political issues with that of the nature of rape.

We present a theoretical view of the cellular foundations for network-level processes involved in producing our conscious experience. Inputs to apical synapses in layer 1 of a large subset of neocortical cells are summed at an integration zone near the top of their apical trunk. These inputs come from diverse sources and provide a context within which the transmission of information abstracted from sensory input to their basal and perisomatic synapses can be amplified when relevant. We argue that apical amplification (...) enables conscious perceptual experience and makes it more flexible, and thus more adaptive, by being sensitive to context. Apical amplification provides a possible mechanism for recurrent processing theory that avoids strong loops. It makes the broadcasting hypothesized by global neuronal workspace theories feasible while preserving the distinct contributions of the individual cells receiving the broadcast. It also provides mechanisms that contribute to the holistic aspects of integrated information theory. As apical amplification is highly dependent on cholinergic, aminergic, and other neuromodulators, it relates the specific contents of conscious experience to global mental states and to fluctuations in arousal when awake. We conclude that apical dendrites provide a cellular mechanism for the context-sensitive selective amplification that is a cardinal prerequisite of conscious perception. (shrink)

In this paper, we defend two main claims. The first is a moderate claim: we have a negative duty to not use binary gender-specific pronouns he or she to refer to genderqueer individuals. We defend this with an argument by analogy. It was gravely wrong for Mark Latham to refer to Catherine McGregor, a transgender woman, using the pronoun he; we argue that such cases of misgendering are morally analogous to referring to Angel Haze, who identifies as genderqueer, as he (...) or she. The second is a radical claim: we have a negative duty to not use any gender-specific pronouns to refer to anyone, regardless of their gender identity. We offer three arguments in favor of this claim (which appeal to concerns about inegalitarianism and risk, invasions of privacy, and reinforcing essentialist ideologies). We also show why the radical claim is compatible with the moderate claim. Before concluding, we examine common concerns about incorporating either they or a neologism such as ze as a third-person singular gender-neutral pronoun. These concerns, we argue, do not provide sufficient reason to reject either the moderate or radical claim. (shrink)

Gender classifications often are controversial. These controversies typically focus on whether gender classifications align with facts about gender kind membership: Could someone really be nonbinary? Is Chris Mosier really a man? I think this is a bad approach. Consider the possibility of ontological oppression, which arises when social kinds operating in a context unjustly constrain the behaviors, concepts, or affect of certain groups. Gender kinds operating in dominant contexts, I argue, oppress trans and nonbinary persons in this way: they marginalize (...) trans men and women, and exclude nonbinary persons. As a result, facts about membership in dominant gender kinds should not settle gender classification practices. (shrink)

We want to know what gender is. But metaphysical approaches to this question solely have focused on the binary gender kinds men and women. By overlooking those who identify outside of the binary–the group I call ‘genderqueer’–we are left without tools for understanding these new and quickly growing gender identifications. This metaphysical gap in turn creates a conceptual lacuna that contributes to systematic misunderstanding of genderqueer persons. In this paper, I argue that to better understand genderqueer identities, we must recognize (...) a new type of gender kind: critical gender kinds, or kinds whose members collectively destabilize one or more pieces of dominant gender ideology. After developing a model of critical gender kinds, I suggest that genderqueer is best modeled as a critical gender kind that destabilizes the ‘binary axis’, or the piece of dominant gender ideology that says that the only possible genders are the binary, discrete, exclusive, and exhaustive kinds men and women.

Ordinary discourse is filled with discussions about ‘sexual orientation’. This discourse might suggest a common understanding of what sexual orientation is. But even a cursory search turns up vastly differing, conflicting, and sometimes ethically troubling characterizations of sexual orientation. The conceptual jumble surrounding sexual orientation suggests that the topic is overripe for philosophical exploration. This paper lays the groundwork for such an exploration. In it, I offer an account of sexual orientation – called ‘Bidimensional Dispositionalism’ – according to which sexual (...) orientation concerns what sex[es] and gender[s] of persons one is disposed to sexually engage, and makes no reference to one’s own sex and gender.

Alex Byrne’s article, “Are Women Adult Human Females?”, asks a question that Byrne treats as nearly rhetorical. Byrne’s answer is, ‘clearly, yes’. Moreover, Byrne claims, 'woman' is a biological category that does not admit of any interpretation as (also) a social category. It is important to respond to Byrne’s argument, but mostly because it is paradigmatic of a wider phenomenon. The slogan “women are adult human females” is a political slogan championed by anti-trans activists, appearing on billboards, pamphlets, and anti-trans (...) online forums. In this paper, I respond to Byrne’s argument, revealing significant problems with its background assumptions, content, and methodology. (shrink)

There has been extensive discussion of testimonial epistemic injustice, the phenomenon whereby a speaker’s testimony is rejected due to prejudice regarding who they are. But people also have their testimony rejected or preempted due to prejudice regarding what they communicate. Here, the injustice is content focused.

What’s important about ‘coming out’? Why do we wear business suits or Star Trek pins? Part of the answer, we think, has to do with what we call agential identity. Social metaphysics has given us tools for understanding what it is to be socially positioned as a member of a particular group and what it means to self-identify with a group. But there is little exploration of the general relationship between self-identity and social position. We take up this exploration, developing (...) an account of agential identity—the self-identities we make available to others. Agential identities are the bridge between what we take ourselves to be and what others take us to be. Understanding agential identity not only fills an important gap in the literature, but also helps us explain politically important phenomena concerning discrimination, malicious identities, passing, and code-switching. These phenomena, we argue, cannot be understood solely in terms of self-identity or social position. (shrink)

We live in a world saturated in both racial and gendered divisions. Our focus is on one place where attitudes about these divisions diverge: language. We suspect most everyone would be horrified at the idea of adding race-specific pronouns, honorifics, generic terms, and so on to English. And yet gender-specific terms of the same sort are widely accepted and endorsed. We think this asymmetry cannot withstand scrutiny. We provide three considerations against incorporating additional race-specific terms into English, and argue that (...) these considerations also support eliminating the analogous gender-specific terms. With respect to these parts of speech, English should be no more gender-specific than it already is race-specific. (shrink)

In this article, Dembroff argues that the category nonbinary should not be understood in terms of presentation or psychological states, but instead in terms of how its members are politically situated with respect to the binary expectations of Western gender ideology.

When one takes an intersectional perspective on patterns of oppression and domination, it becomes clear that familiar forms of systemic injustice, such as misogyny and anti-Black racism, are inseparable. Some feminist theorists conclude, from this, that the systems behind these injustices cannot be individuated—for example, that there isn’t patriarchy and white supremacy, but instead only white supremacist patriarchy. This chapter offers a different perspective. Philosophers have long observed that a statue and a lump of clay can be individuated although inseparable, (...) and that statues and lumps of clay do different explanatory and predictive work for the same causal outcomes. This chapter suggests that the same is true of systems such as patriarchy and white supremacy. These systems, like the injustices they produce, are inseparable. But they can be individuated, and when they are individuated, they do different explanatory and predictive work. (shrink)

In her provocative discussion of the challenge posed to the traditional impartialist, justice-focused conception of morality by the new-wave care perspective in ethics, Annette Baier calls for ‘a “marriage” of the old male and newly articulated female... moral wisdom,’ to produce a new ‘cooperative’ moral theory that ‘harmonize[s] justice and care.’ I want in this paper to play matchmaker, proposing one possible conjugal bonding: a union of two apparently dissimilar modes of what Nel Noddings calls ‘meeting the other morally,’ a (...) wedding of respect and care.

The target of this paper is the ‘simple’ knowledge account of assertion, according to which assertion is constituted by a single epistemic rule of the form ‘One must: assert p only if one knows p’. My aim is to argue that those who are attracted to a knowledge account of assertion should prefer what I call the ‘complex’ knowledge account, according to which assertion is constituted by a system of rules all of which are, taken together, constitutive of assertion. One (...) of those rules—which, following John Searle, I call the ‘preparatory condition’—is of the form ‘One must: assert p only if one knows p.’ All else being equal, simple accounts are preferable to complex accounts. I argue in this paper that all else isn't equal. While the simple knowledge account provides an elegant explanation of certain data, it is hard to see how to integrate the simple knowledge account into a more general theory of illocutionary acts. Because the complex knowledge account avoids this objection whil.. (shrink)

Analytic philosophy has transgender trouble. In this paper, I explore potential explanations for this trouble, focusing on the notion of 'cisgender commonsense' and its place in philosophical methodology.

In this peer commentary on Maura Priest's "Transgender Children and the Right to Transition: Medical Ethics When Parents Mean Well but Cause Harm", I argue against the "mismatch" model of trans identity. On this model, which is prevalent in institutional and medical contexts, to be trans is to have one's gender identity "mismatch" with one's sexed body.

Many of us hold false beliefs about matters that are relevant to public policy such as climate change and the safety of vaccines. What can be done to rectify this situation? This question can be read in two ways. According to the descriptive reading, it concerns which methods will be effective in persuading people that their beliefs are false. According to the normative reading, it concerns which methods we are permitted to use in the service of persuading people. Some effective (...) methods—a programme of brainwashing, say—would not be permissible. In this paper I compare “methods of rational persuasion” with what you might call “marketing methods” such as how one frames the problem of climate change. My aim is to show that “marketing methods” are preferable to “methods of rational persuasion”. My argument has two parts. First, I argue that the evidence suggests that “marketing methods” are more effective in persuading people to change their minds. Second, I argue that “marketing methods” are an acceptable response to the normative question. (shrink)

One of the moral questions concerning autonomous vehicles (henceforth AVs) is the choice between types that differ in their built-in algorithms for dealing with rare situations of unavoidable lethal collision. It does not appear to be possible to avoid questions about how these algorithms should be designed. We present the results of our study of moral preferences (N = 2769) with respect to three types of AVs: (1) selfish, which protects the lives of passenger(s) over any number of bystanders; (2) (...) altruistic, which minimizes the number of casualties, even if this leads to death of passenger(s); and (3) conservative, which abstains from interfering in such situations. We differentiate between scenarios in which participants are to make their decisions privately or publicly, and for themselves or for their offspring. We aim to answer two research questions: (1) whether the public visibility of the choice of an AV type choice make this choice more altruistic and (2) which type of situation makes it more difficult to choose altruistically: when choosing for society as a whole, when choosing only for oneself, or when choosing only for one’s offspring. Our results show that respondents exhibit a preference for an altruistic strategy for AVs and that it is reinforced when signaled to others. The altruistic preference is strongest when applies to everybody else, weaker when it reflects a solely personal choice, and weakest when choosing for one’s own child. We conclude that a public choice is considerably more likely to pressure consumers into accepting a more socially beneficial solution. (shrink)

Epistemic contextualists think that the truth-conditions of ‘knowledge’ ascriptions depend in part on the context in which they are uttered. But what features of context play a role in determining truth-conditions? The idea that the making salient of error possibilities is a central part of the story has often been attributed to contextualists, and a number of contextualists seem to endorse it (see Cohen (Philos Perspect, 13:57–89, 1999) and Hawthorne, (Knowledge and lotteries, Oxford University Press, Oxford, 2004)). In this paper (...) I argue that the focus on salience relations is a mistake. On the view I defend, the relevant features of context are facts about what error-possibilities and alternatives those in the context have a reason to consider, not facts about what error-possibilities and alternatives those in the context actually consider. As I will argue, this view has certain advantages over the standard view. (shrink)

The idea that the concept ‘knowledge’ has a distinctive function or social role is increasingly influential within contemporary epistemology. Perhaps the best-known account of the function of ‘knowledge’ is that developed in Edward Craig’s Knowledge and the state of nature (1990, OUP), on which (roughly) ‘knowledge’ has the function of identifying good informants. Craig’s account of the function of ‘knowledge’ has been appealed to in support of a variety of views, and in this paper I’m concerned with the claim that (...) it supports a sort of epistemic contextualism, which is (roughly) the view that the semantic contents and truth-conditions of ‘knowledge’ ascriptions - instances of ‘S knows that p’- depend on and vary with the context of ascription (see, for instance, John Greco’s ‘What’s wrong with contextualism’, Philosophical Quarterly [2008]). Prima facie, this claim should strike us as surprising. A number of concepts and linguistic items (words, sentences) serve functions that have little or nothing to do with semantics. However, I argue that, on the best interpretation of talk of the function of a concept such as ‘knowledge’, the function of ‘knowledge’ is relevant to semantics. Along the way I also suggest how to improve on what I call the ‘usual argument’ that Craig’s account of the function of ‘knowledge’ supports epistemic contextualism. (shrink)

In a recent article in this journal, Mona Simion argues that Sally Haslanger’s “engineering” approach to gender concepts such as ‘woman’ faces an epistemic objection. The primary function of all concepts—gender concepts included—is to represent the world, but Haslanger’s engineering account of ‘woman’ fails to adequately represent the world because, by her own admission, it doesn’t include all women in the extension of the concept ‘woman.’ I argue that this objection fails because the primary function of gender concepts—and social kind (...) concepts in general—is not (merely) to represent the world, but rather to shape it. I finish by considering the consequences for “conceptual engineering” in philosophy more generally. While Haslanger’s account may escape Simion’s objection, other appeals to conceptual engineering might not fair so well. (shrink)

Recent work in psychology on ‘cultural cognition’ suggests that our cultural background drives our attitudes towards a range of politically contentious issues in science such as global warming. This work is part of a more general attempt to investigate the ways in which our wants, wishes and desires impact on our assessments of information, events and theories. Put crudely, the idea is that we conform our assessments of the evidence for and against scientific theories with clear political relevance to our (...) pre-existing political beliefs and convictions. In this paper I explore the epistemological consequences of cultural cognition. What does it mean for the rationality of our beliefs about issues such as global warming? I argue for an unsettling conclusion. Not only are those on the ‘political right’ who reject the scientific consensus on issues like global warming unjustified in doing so, some of those on the ‘political left’ who accept the consensus are also unjustified in doing so. I finish by addressing the practical implications of my conclusions. (shrink)

Many have rejected contextualism about ?knows? because the view runs into trouble with intra- and inter-contextual disagreement reports. My aim in this paper is to show that this is a mistake. First, I outline four desiderata for a contextualist solution to the problem. Second, I argue that two extant solutions to the problem fail to satisfy the desiderata. Third, I develop an alternative solution which satisfies the four desiderata. The basic idea, put roughly, is that ?knowledge? ascriptions serve the function (...) of recommending good informants, and disagreement over ?knowledge? ascriptions is a matter of conflicting recommendations. The upshot is that intra- and inter-contextual disagreement reports provide little?if any?reason to reject contextualism. (shrink)

Epistemic contextualists think that the extension of the expression ‘knows’ depends on and varies with the context of utterance. In the last 15 years or so this view has faced intense criticism. This paper focuses on two sorts of objections. The first are what I call the ‘linguistic objections’, which purport to show that the best available linguistic evidence suggests that ‘knows’ is not context-sensitive. The second is what I call the ‘disagreement problem’, which concerns the behaviour of ‘knows’ in (...) disagreement reports. These may not be the only objections to epistemic contextualism, but they are probably the most influential. I argue that the best current epistemic contextualist response to the linguistic objection is incomplete, and I show how it can be supplemented to deal with the full range of linguistic objections. I also develop a new solution to the disagreement problem. The upshot is that neither sort of objection gives us any reason to reject epistemic contextualism. This conclusion is, in a sense, negative—no new arguments for epistemic contextualism are advanced—but it’s a vital step towards rehabilitating the view. (shrink)

It is commonly observed that we live in an increasingly polarised world. Strikingly, we are polarised not only about political issues, but also about scientific issues that have political implications, such as climate change. This raises two questions. First, why are we so polarised over these issues? Second, does this mean our views about these issues are all equally ir/rational? In this chapter I explore both questions. Specifically, I draw on the literature on ideologically motivated reasoning to develop an answer (...) to the first question. Put briefly, we exhibit “directional biases” in our information processing: we try to assimilate new information into our existing webs of beliefs. This means that those who are predisposed to accept the case for climate change end up accepting it, whereas those who are predisposed to reject it end up rejecting it. Based on this answer, I then address the second question. I look at some reasons for thinking that, because we all exhibit such biases in our thinking, we are all equally rational (or, as the case may be, irrational). I also suggest some ways you might try reject these reasons. (shrink)
