Autonomous and automatic weapons would be fire and forget: you activate them, and they decide who, when and how to kill; or they kill at a later time a target you’ve selected earlier. Some argue that this sort of killing is always wrong. If killing is to be done, it should be done only under direct human control. (E.g., Mary Ellen O’Connell, Peter Asaro, Christof Heyns.) I argue that there are surprisingly many kinds of situation where this is false and (...) where the use of Automated Weapons Systems would in fact be morally required. These include cases where a) once one has activated a weapon expected then to behave lethally, it would be appropriate to let it continue because this is part of a plan whose goodness one was best positioned to evaluate before activating the weapon; b) one expects better long-term consequences from allowing it to continue; c) allowing it to continue would express a decision you made to be resolute, a decision that could not have advantaged you had it not been true that you would carry through with it; d) the weapon is mechanically not recallable, so that, to not allow it to carry through, you would have had to refrain from activating it in the first place, something you expected would have disastrous consequences; e) you must deputize necessary killings to autonomous machines in order to protect yourself from guilt you shouldn’t have to bear; f) it would be morally better for the burden of responsibility for the killing to be shared among several agents, and the agents deputizing killing to machines can do this, especially where it’s not predictable which machine will be successful; g) a killing would be morally better done with elements of randomness and lack of deliberation, and a (relatively stupid) machine could do this where a person could not; h) the machine would be acting as a Doomsday Device, so that it could not have had its hoped for deterrent effect had you not ensured that you would be unable to recall it if enemy action activated it; i) letting it carry through is a necessary part of its own learning process, and you expect that this learning will have salutary effects later on; j) human intervention in the machine’s operation would disastrously impair its precision, or its speed and efficiency; k) using non-automated methods would require human resources you just don’t have in a task that nevertheless must be done (e.g., using land-mines to protect remote installations); l) the weapon has such horrible and indiscriminate power that it is doubtful whether it could be actually used in ways compatible with International Humanitarian Law and the Laws of War, which require that weapons be used only in ways respecting distinctness, necessity and proportionality, but its threat of use could respect these principles in affording deterrence provided human error cannot lead to their accidental deployment, this requiring that they be controlled by carefully designed autonomous and automatic systems. I then consider objections based on conceptions of human dignity and find that very often dignity too is best served by autonomous machine killing. Examples include saving your village by activating a robot to kill invading enemies who would inflict great indignity on your village, using a suicide robot to save yourself from a less dignified death at enemy hands, using a robotic drone to kill someone otherwise not accessible in order to restore dignity to someone this person killed and to his family, and using a robot to kill someone who needs killing, but the killing of whom by a human executioner would soil the executioner’s dignity. I conclude that what matters in rightful killing isn’t necessarily that it be under the direct control of a human, but that it be under the control of morality; and that could sometimes require use of an autonomous or automated device.

An Address delivered to the Seattle G. K. Chesterton Society at the University of Washington Newman Center, May 2, 2013.

This chapter both explains the origins of emotivism in C. K. Ogden and I. A. Richards, R. B. Braithwaite, Austin Duncan-Jones, A. J. Ayer and Charles Stevenson (along with the endorsement by Frank P. Ramsey, and the summary of C. D. Broad), and looks at MacIntyre's criticisms of emotivism as the inevitable result of Moore's attack on naturalistic ethics and his ushering in the fact/value, which was a historical product of the Enlightenment.

REPRODUÇÃO ANIMAL: TRANSFERÊNCIA DE EMBRIÕES EM ANIMAIS, E A INDÚSTRIA DE EMBRIÕES NO BRASIL -/- ANIMAL BREEDING: EMBRYO TRANSFER IN ANIMALS, AND THE EMBRYO INDUSTRY IN BRAZIL Apoio: Emanuel Isaque Cordeiro da Silva Departamento de Zootecnia da UFRPE E-mail: [email protected] WhatsApp: (82)98143-8399 -/- 1. INTRODUÇÃO A técnica da inseminação artificial tornou possível aumentar o impacto na descendência de touros geneticamente superiores em termos de produção láctea das filhas. Com a transferência de embriões é possível aumentar o impacto da fêmea sobre (...) a população das filhas. A transferência de embriões data de 1890, ano em que Heape obteve o nascimento de coelhos transferindo ovócitos fecundados de uma fêmea para outra. A partir de 1930, é repetida uma série de experiências para desenvolver a técnica e aplicá-la em ovinos, caprinos (1934) e bovinos (1951) como espécies mais idôneas para a reprodução. A Inglaterra e os Estados Unidos estabeleceram as bases para o comércio de embriões durante os anos sessenta e setenta. De forma resumida, a transferência de embriões implica na estimulação da produção de ovócitos mediante a aplicação de hormônios: cerca de 6-8 dias após a cobrição dessas fêmeas ou da sua inseminação artificial, os óvulos fertilizados são extraídos dos órgãos genitais da fêmea doadora por perfusão ou lavagem com soluções biológicas controladas e testadas, originando-se uma deposição dos gametas fecundados nas fêmeas receptoras que serão encarregadas de levar adiante a gestação e o parto sem influência sobre as produções do novo indivíduo. 2. MANEJO DAS FÊMEAS DOADORAS É relativamente fácil obter um embrião, uma vez que pode origina-se a partir do cio natural das vacas cíclicas. No entanto, a fim de otimizar a técnica, o normal é «superovular» a fêmea doadora e obter um número superior de gametas fecundadas após cada lavagem ou perfusão das genitais. A maioria das fêmeas doadoras são tratadas com gonadotrofinas (PMSG) ou com hormônios estimuladores da foliculogênese (FSH). Estes hormônios invertem a atresia normal de folículos permitindo uma maturação, que em condições normais não se realizaria. O mecanismo exato do funcionamento destas hormonas não é totalmente claro. A superovulação multiplica por um fator de 10 o número de ovócitos recuperados no caso das vacas, ovelhas e cabras, mas apenas por um fator 2 ou 3 no caso das porcas. Existe um acordo geral sobre a utilização das gonadotrofinas; a PMSG deve ser aplicada durante a transição da fase luteica para a folicular, ou seja, no 16º dia do ciclo. As doses de gonadotrofinas variam entre 1500 e 3000 UI em bovinos, aumentando a resposta e a variabilidade individual com o aumento da dose. A resposta ao tratamento varia de acordo em função de diversos fatores. Neste contexto, merecem especial atenção a espécie, a raça, a época e a conformação corporal do animal, bem como o lote de fabricação da preparação hormonal (quadro 7.1). Estudos demonstram que, nos bovinos, as raças de corte respondem melhor ao tratamento do que as raças leiteiras. Tabela 1: Doses de gonadotrofinas em UI -/- Espécie Dia do ciclo Crescimento folicular_ ___ PMSG FSH Ovulação _____ PMSG FSH Bovinos 8 – 10 1500 – 3000 20 – 50 1500 – 2000 75 – 200 Caprinos 16 – 17 1000 – 1500 12 – 20 1000 – 1500 50 – 75 Ovinos 12 – 14 1000 – 2000 12 – 20 1000 – 1500 50 – 75 Suínos 15 – 17 750 – 1500 10 – 20 500 – 1000 25 – 50 Coelhos — 25 – 75 2 – 3 25 – 75 2 – 3 Fonte: HAFEZ, 2004. O FSH também é utilizado para superovulação em várias espécies. Nos ovinos, injetam-se 2 mg desta hormona 12 horas antes da retirada das esponjas, aplicando-se mais três injeções, com um intervalo de 12 horas, até 24 horas após a retirada das esponjas, o que corresponde a um total de 8 mg de FSH injetados por tratamento e animal. Às vezes, e dependendo do país, existem dificuldades para a obtenção desse hormônio em condições de pureza adequada para que o tratamento proporcione o resultado esperado. Nas vacas dadoras devem ter passado mais de 50 dias após o último parto: também ser animais cíclicos, encontrar-se num nível nutricional elevado e em aumento, sem deficiências especificas alimentares. Existe uma indicação de suplementação das fêmeas doadoras com minerais essenciais antes do tratamento. 3. OBTENÇÃO DE EMBRIÕES Uma vez as fêmeas doadoras inseminadas, entre o sexto e o oitavo dia, procede-se a coleta dos embriões. Para isso, atualmente se utilizam cateteres de obtenção transcervical (tipo Foley, Rusch. etc.) munidos de uma bola insuflável na sua extremidade que permite criar um compartimento estanque na parte distal do córneo uterino e proceder ao arrasto dos embriões ali localizados. Para obter esta «lavagem» utiliza-se uma solução aquosa tamponada: o meio mais frequentemente utilizado é o tampão fosfato salino (PBS: pH = 7; PO = 280 - 290 mOsm/kg) suplementado com antibióticos e proteínas. Depois de recuperado o meio de lavagem, os embriões devem ser isolados do volume total, avaliados segundo critérios do Manual da Sociedade Internacional de Transferência de Embriões de acordo com seu estado de desenvolvimento. Código numérico para determinar o grau de desenvolvimento embrionário: N° 1: ovócito não fertilizado ou embrião de uma célula (1 dia). N° 2: Identifica embriões com 2 a 16 células (2-4 dias). N° 3: Identifica mórulas adiantadas (5-6 dias). N° 4: Identifica mórulas compactas de 6 dias de idade. N° 5: blastocisto adiantado (7 dias). N° 6: blastocisto (7-8 dias). N° 7: blastocisto expandido (8-9 dias). N° 8: blastocisto eclodido (9 dias) a partir do nono ou décimo dia o blastocisto já está fora da zona pelúcida. Além da classificação por estado de desenvolvimento, a referida Sociedade Internacional estabeleceu uma categorização dos embriões com base na qualidade dos mesmos. Assim os denomina: 1: excelente; 2: bom; 3: regular; 4: degenerado. Segundo as investigações de diversos autores especialistas no tema não devem ser transferidos embriões que não tenham sido classificados como excelentes ou bons. A obtenção dos embriões pode ser realizada em uma clínica, em unidades móveis especializadas, ou na própria fazenda. Em todo o caso, a doadora não deve apresentar quaisquer sintomas clínicos de doença, sendo esta responsabilidade direta do veterinário. O rebanho de onde provém a doadora deve estar livre de medidas cautelares sanitárias. Os técnicos devem estar adequadamente limpos e preparados para esta atuação, em um lugar tranquilo e que permita a colocação de equipamentos e material em condições limpas e seguras. 4. TÉCNICAS DE TRANSFERÊNCIA DE EMBRIÕES Recomenda-se que os embriões sejam transferidos o mais rápido possível depois da recuperação. A fêmea receptora deve apresentar um ambiente uterino o mais semelhante possível ao da fêmea doadora. Isto quer dizer que a receptora também será mantida num sistema de sincronização para que coincida o mais possível o estágio de desenvolvimento embrionário com seu correspondente estado uterino. A margem de assincronia para evitar efeitos indesejáveis é de ± 24 horas. Os métodos hormonais de sincronização são análogos aos das doadoras. As técnicas para a deposição dos embriões no seu novo habitat podem ser igualmente cirúrgicas e não cirúrgicas, mas devido aos problemas do uso de anestésicos em técnicas cirúrgicas, as transferências foram direcionadas para modelos não-cirúrgicos ou transcervicais. Este método é baseado na utilização do colo uterino de forma análoga como é realizada na inseminação artificial. Devido às relações entre o embrião e o ovário, as porcentagens de fertilidade são aumentadas ao serem depositadas no corno ipsilateral no ovário que se encontra ativo. A utilização desta técnica implica na obtenção de mais fêmeas gestantes. O uso de novilhas como fêmeas receptoras aumenta também a taxa de gestações a partir de uma maior facilidade de manejo, uniformidade na resposta hormonal e um custo mais baixo. O fator humano ou habilidade do técnico que realiza esta técnica também constitui um fator que influencia decisivamente no êxito da transferência, encontrando-se variações de 20 a 60% devidas a este fator. 5. CONTROLES SANITÁRIOS Com a utilização da inseminação artificial, verificou-se que, embora as tecnologias reprodutivas colaborativas fossem mais avançadas em termos de técnicas destinadas a aumentar a produtividade individual, da mesma forma, podem constituir um perigo de contaminação e de dispersão de doenças estrangeiras para o grupo ou rebanho para onde são transferidos os novos genes. Neste contexto, a transferência embrionária (TE) deve realizar-se tendo em conta os riscos que pode implicar uma manipulação inadequada. Uma vez mais, a Sociedade Internacional (IETS) na Reunião Regional da OIE (Oficina Internacional de Epizootias) estabeleceu as normas em 1985 para que a TE pudesse ser utilizada como meio para controle de doenças na pecuária. Para que a utilização da TE se realize sem risco para a saúde, é necessário ter em conta um certo número de regras e condições específicas que evitem os riscos de contaminação. O embrião está separado do meio externo por três barreiras de proteção: o corpo da mãe, o útero por si só e a terceira, e mais importante, pela zona pelúcida, a qual nos animais domésticos tem demonstrado ser totalmente impermeável a qualquer elemento patogênico, desde que fique intacta. Portanto, o risco de contaminação dos embriões pode vir por duas vias diferentes: a) Fatores extrínsecos - por invasão dos agentes patogênicos na cavidade uterina principalmente. Isto está relacionado com o estado sanitário médio do país, região ou rebanho de origem. b) Fatores intrínsecos - Segundo Thibier podemos considerar diferentes fontes potenciais de contaminação, que segundo o risco sanitário se classificam nas seguintes ordens: 1° Zigoto. 2° Penetração. 3° Absorção. 4° Armazenamento. 5° Exame. 6° Transferência. Os esforços para que os embriões se tornem livres de contaminação devem ser semelhantes aos que são efetuados com os animais vivos e com as doses seminais. O momento mais perigoso encontra-se entre a coleta das células fecundadas e a sua deposição, após seu exame, no trato reprodutivo da receptora. As condições em que o referido processo deve ser realizado encontram-se detalhadas no manual da Sociedade Internacional de Transferência de Embriões (IETS). 6. REGRAS DA IETS A transferência de embriões é a via mais segura para a troca de genes. No entanto, os técnicos devem esforçar-se por manter todas as regras e normas sanitárias para que a coleta e a manipulação dos embriões se realizem sob condições de absoluta garantia higiênica e sanitária. A transferência embrionária implica, pela primeira vez na história da medicina veterinária, que a vigilância sanitária não se aplica estritamente ao animal, uma vez que, na sua fase "in vitro", está inteiramente sob o controle do técnico. Por conseguinte, não haverá futuro para este tipo de biotecnologia se, paralelamente, não houver um elevado nível de garantia de que não «servirá» para não disseminar ou difundir doenças. As conclusões da Sociedade Internacional de Transferência de Embriões (IETS) na sua reunião anual de 14 de Janeiro de 1992 estabelecem, tendo em conta a revisão efetuada em 1991 pela Subdireção de Investigação e pelo Comitê de Importação e Exportação, uma classificação das doenças. Esta classificação corresponde às seguintes categorias: Categoria 1 - Doenças ou agentes de doenças para as quais foram recolhidas provas suficientes para afirmar que o risco de transmissão é negligenciável, desde que os embriões sejam corretamente manipulados entre a coleta e a transferência: a) Leucose bovina enzoótica. b) Febre aftosa (bovinos). c) Língua azul (bovinos). d) Brucelose bovina. e) Rintraqueíte infecciosa bovina. f) Doença de Aujeszky. Categoria 2 - Doenças para as quais foram recolhidas provas substanciais que indicam que o risco de transmissão é insignificante, desde que os embriões sejam corretamente manipulados entre a coleta e a transferência, mas para as quais é necessário verificar os dados existentes através de novas transferências: a) Peste suína clássica. Categoria 3 - Doenças ou agentes de doenças para as quais os resultados preliminares indicam que o risco de transmissão é insignificante, desde que os embriões sejam corretamente manipulados, entre a coleta e a transferência, mas para os quais essas verificações preliminares devem ser corroboradas por dados experimentais complementares "in vitro" e "in vivo": a) Peste bovina. b) Diarreia viral bovina. c) Língua azul (ovinos). d) Febre aftosa (suínos, ovelhas e cabras). e) Campylobacter fetus (ovinos). f) Doença vesicular do porco. g) Peste suína africana. h) Prurido lombar (ovinos). i) Haemophilus somnus. Categoria 4 - Doenças ou agentes de doenças que foram ou são objeto de trabalhos preliminares: a) Vírus Akabane (bovino). b) Estomatite vesicular (bovinos e suínos). c) Chlamydia psittaci (bovinos e suínos). d) Ureaplasma/micoplasmose (bovinos e caprinos). e) Maedi-visna (ovino). f) Adenomatosa pulmonar (ovino). g) Prurido lombar (caprinos). h) Língua azul (caprinos). i) Artrite e encefalite caprina. j) Parvovírus (suíno). k) Enterovírus (bovinos e suínos). I) Leptospirose (suíno). m) Herpesvírus 4 dos bovinos. n) Mycobacterium paratuberculose (bovinos). o) brucelose ovina. p) Doença de Border (ovinos). q) Vírus parainfluenza 3 (bovinos). r) Agente da encefalopatia espongiforme bovina. É interessante salientar que apenas seis doenças estão incluídas na categoria 1 (a mais segura). Isso não significa que as outras doenças tenham um risco maior, apenas indica que o risco de transmissão das doenças da categoria 1 é irrelevante, estatisticamente falando. É importante assinalar que as doenças mais importantes dos bovinos se situam na categoria 1. Isto significa que a incidência do embrião patogênico nos bovinos parece ser perfeitamente controlável, desde que sejam adotadas metodologias adequadas. Isto serve também como linha de defesa adicional para que o técnico centre sua atenção e cuidados entre a fase de obtenção e a de transferência. 7. SITUAÇÃO ATUAL DA TRANSFERÊNCIA DE EMBRIÕES ANIMAIS NO BRASIL O Brasil é um dos grandes responsáveis mundiais pela implantação da tecnologia na reprodução animal, sendo assim, o país conseguiu inserir-se no mercado internacional como um dos maiores produtores de embriões in vivo e in vitro. Nas últimas duas décadas, especialmente entre os anos de 1997 e 2017 o país passou por importantes transformações nesse segmento, dentre essas transformações vale destacar a posição relativa do Brasil no contexto mundial. O Brasil passou de referência regional, nos anos 1990, para se tornar o maior produtor mundial de embriões entre os anos 2012 e 2013, sendo líder no uso e na produção de embriões in vitro. Os primeiros registros da TE produzidos in vivo no Brasil datam da década de 1980, e uma década depois o país já tornara-se referência e detinha um mercado consolidado de produção e TE na espécie bovina. Não obstante, no ano de 1997 o país ainda era referência apenas no contexto regional, detendo 68,3% dos embriões transferidos na América Latina, esse percentual corresponde a 24.085 embriões de um total de 35.254 produzidos na América Latina. Esse percentual regional representa apenas 6,6% de toda a produção mundial de embriões in vivo, que produziu, em 1997, 360.656 embriões in vivo. Nos últimos anos, o mercado de embriões, principalmente o bovino, teve retração moderada de -2,5% ao ano entre 2003 e 2018, porém essa retração contrasta com o ligeiro crescimento observado a partir dos anos 2000 conforme figura 1: Figura 1: Produção de embriões bovinos no Brasil no período 1996-2018, total e por tecnologia adotada (in vivo[IVD] ou in vitro [IVP]). Em 2018, o mercado de embriões bovinos manteve-se inalterado se compararmos com os três anos anteriores, houve reduções nós segmentos de corte, leite e no total comparado ao ano de 2017. Em 2014, a produção de embriões para melhoramento do gado leiteiro teve seu ápice, porém de lá para cá esse mercado manteve-se estagnado como demonstra a tabela 2. Tabela 2: Produção de embriões bovinos no Brasil em 2018, estratificada por segmento e por tecnologia adotada (in vivo ou in vitro). 7.1 Crise, economia e mercado de embriões A indústria de embriões reflete, em maior ou menor grau, o momento da economia brasileira. Apesar do segmento agropecuário ser um setor em constante crescimento no país, ao qual, sem dúvidas, em meio a inúmeras crises mantém-se em constante crescimento. Porém vale ressaltar que esse mercado é emergente e está refletido em paralelo com os bens produzidos pelo país, como demonstra a figura 2. Figura 2: Produção de embriões bovinos e variação no produto interno bruto (PIB) no Brasil, no período 1996-2018. Cada vez mais o setor agropecuário do Brasil investe em novas tecnologias que maximizem o mercado e que melhore a produção dos animais seja no segmento corte ou leite. Segundo a OCDE, 1997, essa indústria da produção de embriões é um conjunto de novas técnicas e processos, frutos do desenvolvimento técnico-científico, que chega ao mercado e - o mais importante - o transforma. Logo, todas essas técnicas e biotecnologias visam, além da alta produção e do lucro, o melhoramento e a suplementação alimentícia da população mundial que está em crescente avanço. A evolução da tecnologia embrionária no país, seja para o melhoramento dos equinos para os esportes como as vaquejadas, hipismo, corridas, etc., onde são investidos tempo, dedicação e dinheiro para formar um novo animal que apresente força, conformação, conversão alimentar e que custa milhões, em muitos casos, não só dos equinos, mas também dos caprinos, ovinos, suínos e até mesmo os bovinos onde o mercado da TE é mais presente e aquecida, venceu os estigmas do “modismo” e o chamado “elitismo”, porém deve enfrentar novos desafios, em especial num contexto de forte concentração do mercado de genética e de concorrência globalizada. Mesmo com todos esses avanços e retrocessos, essa relativização dos números demonstra que um percentual bastante reduzido das fêmeas bovinas que estão em idade reprodutiva é utilizado para a técnica da transferência de embriões, e que o mercado brasileiro ainda tem um grande potencial de crescimento no setor de produção in vivo e in vitro. 8. RESUMO E PRIMEIRAS CONCLUSÕES Ao longo deste trabalho pretendi realizar uma revisão sumária sobre um tema de grande importância presente, e sobretudo futura; referir-me à transferência embrionária. Atualmente, esta técnica atingiu um grau notável de penetração, a nível prático, no gado leiteiro. No entanto, num futuro mais ou menos longínquo, não temos dúvidas quanto a esta técnica, pelas vantagens indubitáveis que apresenta a nível de avanço genético, que será aplicada em outras espécies úteis ao homem. Na minha exposição, tentei dar especial ênfase a dois aspectos: as técnicas de transferência, incluindo as normas IETS e os controles sanitários a serem efetuados. Por fim, a indústria brasileira de embriões mostrou-se em retrocessos e avanços, porém o mercado ainda têm grandes desafios a serem enfrentados ao longo dos anos, mas que serão sanados mediante as técnicas desenvolvidas pelos inúmeros centros de pesquisa embrionárias e seus especialistas. -/- Realização -/- Emanuel Isaque Cordeiro da Silva – Departamento de Zootecnia da UFRPE.

Investments in mitigating climate change have their greatest environmental impact over the long term. As a consequence the incentives to invest in cutting greenhouse gas emissions today appear to be weak. In response to this challenge, there has been increasing attention given to the idea that current generations can be motivated to start financing mitigation at much higher levels today by shifting these costs to the future through national debt. Shifting costs to the future in this way benefits future generations (...) by break- ing existing patterns of delaying large-scale investment in low-carbon energy and efficiency. As we will see in this chapter, it does appear to be technically feasible to transfer the costs of investments made today to the future in such a way that people alive today do not incur any net cost. the aim of this chapter is to take seriously the possibility that climate change has produced an extremely intractable political problem and that we must now consider strong measures that can break existing patterns of delaying mitigation. I defend the claim that if climate change involves a stark conflict of interests between current and future generations, then borrowing from the future would be both strategically and normatively much better than the status quo. Nevertheless, I challenge the borrowing from the future proposal on the grounds that it is not in fact the powerful tool for motivating existing agents that its proponents imagine it to be. The purpose of developing this critical argument is not, however, simply to throw doubt onto the idea of borrowing from the future. If we really do find ourselves in a political context where the prospects for effective action are very poor then strategic forms of buck-passing may make an important positive contribution to avoiding dangerous global cli- mate change. Consequently, if debt financing is not as powerful of a motivational tool as imagined we still have strong reasons, I will argue, to identify other strategies that will change agents’ incentive structures. To this end, I propose an alternative form of passing on the costs of mitigation to the future that warrants consideration. (shrink)

A powerful argument against the counterfactual comparative account of harm is that it cannot distinguish harming from failing to benefit. In reply to this problem, I suggest a new account of harm. The account is a counterfactual comparative one, but it counts as harms only those events that make a person occupy his level of well-being at the world at which the event occurs. This account distinguishes harming from failing to benefit in a way that accommodates our intuitions about the (...) standard problem cases. In laying the groundwork for this account, I also demonstrate that rival accounts of harm are able to distinguish harming from failing to benefit only if, and because, they also appeal to the distinction between making upshots happen and allowing upshots to happen. One important implication of my discussion is that preserving the moral asymmetry between harming and failing to benefit requires a commitment to the existence of a metaphysical and moral distinction between making and allowing.

Recent studies have shown that recidivism scoring algorithms like COMPAS have significant racial bias: Black defendants are roughly twice as likely as white defendants to be mistakenly classified as medium- or high-risk. This has led some to call for abolishing COMPAS. But many others have argued that algorithms should instead be given access to a defendant's race, which, perhaps counterintuitively, is likely to improve outcomes. This approach can involve either establishing race-sensitive risk thresholds, or distinct racial ‘tracks’. Is there a (...) moral difference between these two approaches? We first consider Deborah Hellman's view that the use of distinct racial tracks (but not distinct thresholds) does not constitute disparate treatment since the effects on individuals are indirect and does not rely on a racial generalization. We argue that this is mistaken: the use of different racial tracks seems both to have direct effects on and to rely on a racial generalization. We then offer an alternative understanding of the distinction between these two approaches—namely, that the use of different cut points is to the counterfactual comparative disadvantage, ex ante, of all white defendants, while the use of different racial tracks can in principle be to the advantage of all groups, though some defendants in both groups will fare worse. Does this mean that the use of cut points is impermissible? Ultimately, we argue, while there are reasons to be skeptical of the use of distinct cut points, it is an open question whether these reasons suffice to make a difference to their moral permissibility.

A common criticism of the use of algorithms in criminal justice is that algorithms and their determinations are in some sense ‘opaque’—that is, difficult or impossible to understand, whether because of their complexity or because of intellectual property protections. Scholars have noted some key problems with opacity, including that opacity can mask unfair treatment and threaten public accountability. In this paper, we explore a different but related concern with algorithmic opacity, which centers on the role of public trust in grounding (...) the legitimacy of criminal justice institutions. We argue that algorithmic opacity threatens the trustworthiness of criminal justice institutions, which in turn threatens their legitimacy. We first offer an account of institutional trustworthiness before showing how opacity threatens to undermine an institution’s trustworthiness. We then explore how threats to trustworthiness affect institutional legitimacy. Finally, we offer some policy recommendations to mitigate the threat to trustworthiness posed by the opacity problem.

This is an introduction to my edited book, the Research Handbook on Liberalism (2024). Some chapters tackle broad, meta-level questions about the coherence and justificatory limits and possibilities of liberalism; others tackle conceptual issues; still others, specific institutional, cultural, historical, and political questions. This introductory chapter is intended to provide a general orientation to these discussions, but also highlight some recurring themes and challenges facing liberalism in an era of rampant inequality, illiberalism, rising autocracies, populism, and massive technological change. I (...) provide a taxonomy of five different kinds of liberalism in play in the field, along with three overarching challenges discussed in the book - the apparent insufficiency, complacency, and self-undermining nature of liberalism. Can contemporary liberalism survive? It can, but not without clearly grasping some of the fundamental challenges it faces today. (shrink)

It is argued that standard accounts of the epistemology of religious commitmentfail to be properly sensitive to certain important features of the nature of religious conviction. Once one takes these features of religious conviction seriously, then it becomes clear that we are not to conceive of the epistemology of religious conviction along completely rational lines.But the moral to extract from this is not fideism, or even a more moderate proposal that casts the epistemic standing of basic religious beliefs along nonrational (...) lines. Rather, one needs to recognise that in an important sense religious convictions are not beliefs at all, but that this is compatible with the idea that many other religious commitments are beliefs. This picture of the nature of religious commitment is shown to fit snugly with the Wittgensteinian account of hinge commitments, such that all rational belief essentially presupposes certain basic arational hinge commitments, along lines originally suggested by John Henry Newman. We are thus able to marshal a parity-style argument in defence of religious commitment. Although religious belief presupposes basic arational religious convictions, it is not on this score epistemically amiss since all belief presupposes basic arational convictions, or hinge commitments. The resulting view of the epistemology of religious commitment is a position I call quasi-fideism. (shrink)

Grey zone attacks tend to paralyze response for two reasons. First, they present us with choice scenarios of inherently dilemmatic structure, e.g., Prisoners’ Dilemmas and games of chicken, complicated by difficult conditions of choice, such as choice under risk or amid vagueness. Second, they exploit our uncertainty about how much we do or should care about the things under attack¬—each attack is small in effect, but their effects accumulate: how should we decide whether to treat a given attack as something (...) meriting a serious response rather than a mere irritation to be ignored? This chapter brings standard decision theoretic tools to bear on the issues, tools such as the maximization of expected utility principle, and the precautionary principle. But it also develops three innovations. It shows that seeing it as possible to make choices not just of actions given our values, but also choices of values themselves, can extricate us from certain kinds of decision paralysis. It shows how we can rationally regard ourselves as having bright decision lines even when nothing in the circumstance of choice has these lines in its structure. And it shows how certain conflict escalation risks from the former two strategies can be managed by both parties seeing that cooperation can yield a sharable surplus of goods, and that cooperation can be rational upon a rationally defensible change in their values so that each comes to derive utility from the success of both parties. This yields cooperative solutions to what amount to Prisoners’ Dilemmas. The Cold War was prosecuted on the logic of strategic rationality and that part of game theory that is deterrence theory. We need a new logic from decision theorists for the games that constitute grey zone conflict. (shrink)

My interest is the kind of philosophical vertigo that is a theme of Cavell’s work on scepticism. This describes the anxiety that is elicited via philosophical engagement with certain kinds of sceptical questions. There is a standing puzzle about this notion of vertigo, however, forcefully pressed, for example, by McDowell. Why should a resolution of the sceptical problem, one that putatively completely undercuts the motivation for scepticism in that domain, nonetheless generate vertigo in this sense? I aim to resolve the (...) puzzle, in a way that I believe underwrites this Cavellian notion, via consideration of Wittgenstein’s remarks on the structure of rational evaluation in his final notebooks, published as On Certainty.

For the tradition, an action is rational if maximizing; for Gauthier, if expressive of a disposition it maximized to adopt; for me, if maximizing on rational preferences, ones whose possession maximizes given one's prior preferences. Decision and Game Theory and their recommendations for choice need revamping to reflect this new standard for the rationality of preferences and choices. It would not be rational when facing a Prisoner's Dilemma to adopt or co-operate from Amartya Sen's "Assurance Game" or "Other Regarding" preferences. (...) But there are preferences which it maximizes to adopt and co-operate from. (shrink)

This paper defends Flatland—the view that there exist neither determination nor dependence relations, and that everything is therefore fundamental—from the objection from explanatory inefficacy. According to that objection, Flatland is unattractive because it is unable to explain either the appearance as of there being determination relations, or the appearance as of there being dependence relations. We show how the Flatlander can meet the first challenge by offering four strategies—reducing, eliminating, untangling and omnizing—which, jointly, explain the appearance as of there being (...) determination relations where no such relations obtain. Since, plausibly, dependence relations just are asymmetric determination relations, we argue that once we come mistakenly to believe that there exist determination relations, the existence of other asymmetries (conceptual and temporal) explains why it appears that there are dependence relations.

This chapter conceptually analyzes the post-traumatic stress injuries called moral injury, moral fatigue or exhaustion, and broken spirit. It then identifies two puzzles. First, soldiers sometimes sustain moral injury even from doing right actions. Second, they experience moral exhaustion from making decisions even where the morally right choice is so obvious that it shouldn’t be stressful to make it; and even where rightness of decision is so murky that no decision could be morally faulted. The injuries result of mistaken moral (...) self-evaluation. Methods of preventing and treating these injuries are defended, including training in self-forgiveness, moral off-loading of actions and decisions to persons and devices less likely to feel inappropriate guilt, and the use of drugs to prevent such guilt. The foregoing has been about moral injury erroneously resulting from the non-violation of a correct moral code. But the chapter then introduces the concept of moral pseudo-injury—felt moral injury that has in reality resulted from violation of a false moral code, so that no one has really been morally injured. This can be used as a method in warfighting. And since the injuries it produces are illusory, this would be morally superior to physical violence. For it causes less injury to its victims, and should cause less guilt in those who must inflict it. Historical precedents are considered. Finally, our enemies often use moral pseudo-injury against us, in the form of terrorist violence against civilians. Terrorism causes comparatively few harms, yet we mistakenly see it as more morally horrific than conventional combat that causes much worse loss of life among armed forces members. Here we need the nuancing and clarifying power of philosophy to restore a sense of proportion, thence to prevent or therapize the moral pseudo-injury we may experience from these sorts of attacks. (This is a pre-penultimate version of the published version, available from OUP at the external link, which contains minor variances. The paper was earlier known as "PTSD Weaponized: A Theory of Moral Injury"; that now superseded version is archived under "past conferences" on the Center for Ethics and the Rule of Law website.).

How may nations protect their interests in space if its fragility makes military operations there self-defeating? This essay claims nations are in Prisoners Dilemmas on the matter, and applies David Gauthier’s theories about how it is rational to behave morally—cooperatively—in such dilemmas. Currently space-faring nations should i) enter into co-operative space sharing arrangements with other rational nations, ii) exclude—militarily, but with only terrestrial force—nations irrational or existentially opposed to other nations being in space, and iii) incentivize all nations into co-operation (...) by redistributing some space-generated wealth to nations that might otherwise ruin space. Further, since all nations are rationally incentivized to ever greater dependence on space, and since each, by threatening space, can hold hostage its benefits to all, each can demand resolution of terrestrial discontents with other nations. So each has a rational interest in treating others morally both in space and on terrestrial issues. (shrink)

In this paper, I argue that neuroscience not only is not complemented, but rather is positively undermined, by the substantive commitments of materialist philosophers of mind. Thus, we can have neuroscience or "neurophilosophy" but not both. Since neuroscience is a real science, to the extent that it is in tension with materialistic neurophilosophy, the latter should be abandoned and the former retained.

Does the Australian state exercise legitimate power over the indigenous peoples within its borders? To say that the state’s political decisions are legitimate is to say that it has the right to impose those decisions on indigenous peoples and that they have a (at least a prima facie) duty to obey. In this paper, I consider the general normative frameworks within which these questions are often grasped in contemporary political theory. Two dominant modes of dealing with political legitimacy are through (...) the politics of ‘recognition’ and ‘justification’. I argue that in order to address the fundamental challenges posed by indigenous peoples to liberal settler states today we need to pluralise our conceptions of political legitimacy. (shrink)

The language of rights pervades modern social and political discourse and yet there is deep disagreement amongst citizens, politicians and philosophers about just what they mean. Who has them? Who should have them? Who can claim them? What are the grounds upon which they can be claimed? How are they related to other important moral and political values such as community, virtue, autonomy, democracy and social justice? In this book, Duncan Ivison offers a unique and accessible integration of, and (...) introduction to, the history and philosophy of rights. He focuses especially on the politics of rights: the fact that rights have always been, and will remain, deeply contested. He discusses not only the historical contexts in which some of the leading philosophers of rights formed their arguments, but also the moral and logical issues they raise for thinking about the nature of rights more generally. At each step, Ivison also considers various deep criticisms of rights, including those made by communitarian, feminist, Marxist and postmodern critics. The book is aimed at students and readers coming to these issues for the first time, but also at more knowledgeable readers looking for a distinctive integration of history and theory as applied to questions about the nature of rights today.

What would it mean to have a suitably ‘realistic’ account of political liberty? On the one hand, I don’t think we can properly understand liberty without an underlying account of personhood or agency.2 In making sense of liberty, we need to ask: What kind of agency does it presuppose or promote? What kind of independence do we care most about? What does it mean to exercise control, or to be self-guiding, in the kind of world we live in today? At (...) the same time, a conception of moral and political personhood needs to be appropriately ‘realistic’: It shouldn’t be over-idealized (or over-simplified), nor demand more than can be reasonably expected, given the kind of creatures we are.

What does the 'colonialist' reading of Locke's political theory suggest about the relationship between liberalism and colonialism in general, as well as the pre-history of liberalism in particular?

There have been two distinctive aspects to James Tully’s approach to the study of imperialism over the years, and both are put to work in these remarkable volumes. The first is his belief in two seemingly contradictory claims: (i) that imperialism is much more pervasive than usually thought (conceptually, historically and practically); and yet (ii) that there are many more forms of resistance to it than usually appreciated. (Part of a symposium in Political Theory on James Tully's 'Public Philosophy in (...) a New Key'). (shrink)

Trust is a crucial condition for the legitimacy and effectiveness of democratic institutions in conditions of deep diversity and enduring injustices. Liberal democratic societies require forms of engagement and deliberation that require trustful relations between citizens: trust is a necessary condition for securing and sustaining just institutions and practices. Establishing trust is hard when there is a lingering suspicion that the institutions citizens are subject to are illegitimate or undermine their ability to participate and deliberate on equal terms. The promise (...) of participation, the appeal to deliberation and inclusion, in other words, is experienced as a form of bad faith. In this paper, I offer four conditions required for democratic trust and discuss them in relation to a series of examples of both democratic mistrust and attempts at rebuilding trust. (shrink)

This chapter discusses the fundamental question of the defense industry’s role and legitimacy for societies. It begins with a parable of a psychopath doing something self-serving that has beneficial moral consequences. Analogously, it is argued, the defense industry profiting by selling weapons that can kill people makes it useful in solving moral problems not solvable by people with ordinary moral scruples. Next, the chapter argues that while the defense industry is a business, it is also implicated in the security of (...) its home nations. In addition, its products can be used for good or evil. Thus, it must navigate conflicting values, with the result that the rules often thought to rightly regulate the industry—codes of business ethics, engineering ethics, procurement ethics, plus laws of the land, and dicta of conscience—need supplementing by general moral reflection. This chapter argues for a principle that tells how to decide when to violate the rules, for a theory of rational choice on which choosing by this principle is rational, and for teaching that theory to defense industry employees to ensure their ethical behavior.

Postcolonial Liberalism presents a compelling account of the challenges to liberal political theory by claims to cultural and political autonomy and land rights made by indigenous peoples today. It also confronts the sensitive issue of how liberalism has been used to justify and legitimate colonialism. Ivison argues that there is a pressing need to re-shape liberal thought to become more receptive to indigenous aspirations and modes of being. What is distinctive about the book is the middle way it charts between (...) separatism, on the one hand, and assimilation, on the other. These two options present a false dichotomy as to what might constitute a genuinely postcolonial liberal society. In defending this ideal, the book addresses important recent debates over the nature of public reason, justice in multicultural and multinational societies, collective responsibility for the past, and clashes between individual and group rights.

In this paper I explore the implications of the notion of hyperspace for scientific realism and the sort of theoretical activity represented by the attempt to arrive at a literal characterization of the noumenal realities that natural science, especially physics, investigates. I conclude that whether or not this enterprise is possible, its being so depends on factors outside of our control for which no internal means of correction is possible. Only a very attenuated form of scientific realism, then, can reasonably (...) be endorsed by sober philosophy. (shrink)

To be acquainted with something (in the philosophical sense of “acquainted” discussed here) is to be directly aware of it. The idea that we are acquainted with certain things we experience has been discussed throughout the history of Western Philosophy, but in the early 20th century it gained especially focused attention among analytic philosophers who drew their inspiration from Bertrand Russell's work on acquaintance. Since then, many philosophers—particularly those working on self‐knowledge or perception—have used the notion of acquaintance to explain (...) various facts about human experience and knowledge. In this paper, I offer an overview of this work, with particular focus on the resurgent literature on acquaintance in contemporary analytic philosophy. After more fully explaining what acquaintance is (or is supposed to be), I describe some reasons for thinking that we are indeed acquainted with certain things we experience, and then I survey some of the facts about experience and knowledge that acquaintance may help explain.

If one can get the targets of one's current wants only by acquiring new wants (as in the Prisoner's Dilemma), is it rational to do so? Arguably not. For this could justify adopting unsatisfiable wants, violating the rational duty to maximize one's utility. Further, why cause a want's target if one will not then want it? And people "are" their wants. So if these change, people will not survive to enjoy their wants' targets. I reply that one rationally need not (...) advance one's future wants, only current ones. Furthermore, rational choice seeks not utility (the co-obtaining of a want and its target), but satisfaction (the eventual obtaining of what is now wanted) -- otherwise, it would be irrational to care now about what happens after one dies. Finally, persons survive "rational" changes of values. Thus reflection on the rational revision of values illuminates the conditions on personal identity and the bases and aims of rational choice.

My aim in this chapter is to take the complexity of our histories of rights as seriously as the nature of rights themselves. Let me say immediately that the point is not to satisfy our sense of moral superiority by smugly pointing out the prejudices found in arguments made over three hundred years ago. We have more than our own share of problems and prejudices to deal with. Rather, in coming to grips with this history, and especially how early-modern political (...) theorists struggled with the extension and application of natural rights to the ‘New World’, we may learn something about our own struggles to extend human rights beyond the boundaries of the state system of which Grotius, Hobbes, Locke and Vattel were among the key intellectual architects. For Richard Tuck, the autonomous rights-bearing agent at the heart of liberal individualism is a product of seventeenth-century theorizing about the nature of the autonomous state acting in the international sphere. The sovereign individual is the ‘traditional cousin of the sovereign state’, argues Tuck, and especially the aggressive, violent, and minimally constrained relative described by Hugo Grotius, Thomas Hobbes, John Locke and Emer de Vattel. Thus the connection between liberalism and imperialism, on this reading, is not merely chronological or historical but metaphysical. The analogy between the sovereign state and the sovereign individual acting on the basis of their natural rights, constrained by the recognition of the basic rights of others (but not much more than that) represents an influential vision of liberal freedom. This minimalist account of freedom represents only one vision, however, and Tuck’s account of the pre-history of liberal rights has to be balanced against other conceptions, including more emancipatory ones.

How does empire become transposed onto justice? There are two kinds of question here, one historical the other conceptual, though they are often entwined. First, we may ask whether there are particular arguments about justice that were subsequently used in the justification of empire or colonialism. Or, we may seek to trace the conceptual structure of argu- ments justifying imperialism to their roots in particular philosophical views, debunking their supposed universalism.3 Second, we may ask about the very nature of the (...) concept of global justice and the values it expresses in relation to other important values. Is the very notion of global justice imperialistic, just because it claims there are universal values applicable to everyone everywhere, whatever their particular ways of life or worldviews?

The original – and often continuing – sin of countries with a settler colonial past is their brutal treatment of indigenous peoples. This challenging legacy continues to confront modern liberal democracies ranging from the USA and Canada to Australia, New Zealand and beyond. Duncan Ivison’s book considers how these states can justly accommodate indigenous populations today. He shows how indigenous movements have gained prominence in the past decade, driving both domestic and international campaigns for change. He examines how the (...) claims made by these movements challenge liberal conceptions of the state, rights, political community, identity and legitimacy. Interweaving a lucid introduction to the debates with his own original argument, he contends that we need to move beyond complaints about the ‘politics of identity’ and towards a more historically and theoretically nuanced liberalism better suited to our times. This book will be a key resource for students and scholars interested in political theory, historic injustice, Indigenous studies and the history of political thought. (shrink)

The central task of this book is to map a subtle but significant addition to the political discourse on liberty since the early modern period; a gradual shift of focus form the individual secure in spheres of non-interference, or acting in accordance with authentic desires and beliefs, to the actions of a self at liberty. Being free stands opposed, classically, to being in someone else’s power, being subject to the will of another – in particular, to being constrained by the (...) intentional actions of others. “Constrained” usually means having choices or opportunities taken away or limited by the designs of others. But what if we press the connection between intentions and constraints a bit further, focusing less on negative constraints and more on enabling ones? Constrained or unfree, that is, not simply through a limitation of choices or options, but where free choices and intentions themselves become the object of theoretical and practical attention. What does it mean to be free or unfree in relation to these kinds of “constraints”? (shrink)

As I walk into a restaurant to meet up with a friend, I look around and see all sorts of things in my immediate environment—tables, chairs, people, colors, shapes, etc. As a result, I know of these things. But what is the nature of this knowledge? Nowadays, the standard practice among philosophers is to treat all knowledge, aside maybe from “know-how”, as propositional. But in this paper I will argue that this is a mistake. I’ll argue that some knowledge is (...) constituted, not by beliefs toward propositions, but by awareness of properties and objects. Seeing isn’t believing, but it is knowing. After further characterizing this type of knowledge, I will make the case for it. Then I will consider a variety of objections. Finally, I will indicate how our recognition of this knowledge may answer other questions, and solve other problems, in philosophy. (shrink)

In this paper, I discuss the Categorical Imperative as a basis for an Ethics of Belief and its application to Kant's own project in his theoretical philosophy.

The two most common accounts of the category of relation are the "toothpick" account of relations and the inherent attribute view of relations. In this essay, I present and defend another traditional account of relations, according to which they are neither real things in their own right nor inherent attributes of things. Instead, they are creatures of reason grounded in objective, non-relational attributes of things. I illustrate this view by reference to the major classes of relations that have some claim (...) to be real or objective - grounded in being. In an appendix, I use this account to discuss what it means to say that the persons of the Trinity are "substantial relations.". (shrink)

In this paper I defend the thesis that, considered simply as certain sorts of bodily sensations, pleasure is not the good nor is pain intrinsically evil. In fact, the opposite is largely the case: pursuit of pleasure is generally productive of ontic evil, and pain, when heeded, directs us toward the ontic good.

This paper works out the scheme of “institutional competences” that underlies the famous Hart and Sacks Legal Process Materials first distributed in final mimeographed form in1958. The Materials were not published during the life times of their authors but were nonetheless a major influence on American legal thought from their first distribution as course materials at Harvard Law School until their abrupt fall from prominence in the early 1970s. The Materials offer the scheme as a solution to the apparent anomaly (...) in a democracy of the law making power in both public and private law of unelected judges serving long terms. The paper critiques the Hart and Sacks solution, called law making through “reasoned elaboration,” which they claimed was sharply distinct from legislative law making or administrative fiat. The paper argues that in both public and private law the materials the judge is to elaborate are characterized by contradictory internal logics. The judge has to choose between them without a meta-criterion. In cases with high stakes, extra-juristic normative orientations, whether moral theories or political ideologies, will come into play, regardless of the judge’s commitment to excluding them. The second part of the paper places Hart and Sacks in a larger historical and comparative context of efforts to solve the problem of social order by way of legal rationality. These two parts were preceded in the original paper by a long discussion, now lost but never very satisfying to me, of the Hart and Sacks theory of “private ordering” in relation to state regulatory power. I wrote the paper for extra credit in the spring of 1970 as a third year student at the Yale Law School. I’ve corrected a few typos but haven’t changed it in any other way. I never published it but it was circulated to a limited extent among Legal Process devotees. Eskridge and Frickey, editors of the Materials as published finally in 1994, credit it, along with another unpublished student paper by Roberto Unger, with hastening the demise of the Materials as a master text. The first part of this version of the paper was recently published in Droit et Philosophie, no. 13, p. 97-117 (2021). (shrink)

Fumerton’s distinctive brand of metaepistemological scepticism is compared and contrasted with the related position outlined by Stroud. It is argued that there are at least three interesting points of contact between Fumerton and Stroud’s metaepistemology. The first point of contact is that both Fumerton and Stroud think that (1) externalist theories of justification permit a kind of non-inferential, perceptual justification for our beliefs about non-psychological reality, but it’s not sufficient for philosophical assurance. However, Fumerton claims, while Stroud denies, that (2) (...) direct acquaintance with facts is sufficient for philosophical assurance. And this is important because Stroud thinks that (3) we have direct perceptual access or acquaintance with facts about the external world, while Fumerton denies this. (shrink)

I argue that Gauthier's constrained-maximizer rationality is problematic. But standard Maximizing Rationality means one's preferences are only rational if it would not maximize on them to adopt new ones. In the Prisoner's Dilemma, it maximizes to adopt conditionally cooperative preferences. (These are detailed, with a view to avoiding problems of circularity of definition.) Morality then maximizes. I distinguish the roles played in rational choices and their bases by preferences, dispositions, moral and rational principles, the aim of rational action, and rational (...) decision rules. I argue that Maximizing Rationality necessarily structures conclusive reasons for action. Thus conations of any sort can base rational choices only if the conations are structured like a coherent preference function; rational actions maximize on such functions. Maximization-constraining dispositions cannot integrate into a coherent preference function. (shrink)

It examines the moral consequences of historical injustice for the descendants of both the perpetrators and the victims and outlines the six questions that any plausible defence of the idea of making reparations for past injustices must deal with.

The debate over the constitutional recognition of Indigenous peoples is a deeply political one. That might appear to be a controversial claim. After all, there has been much talk about minimising the scope for disagreement between ‘constitutional conservatives’ and supporters of more expansive constitutional recognition.

However, my argument shall be that any form of constitutional recognition of Australia’s First Peoples needs to be (...) seen as part of an ongoing transformation in the relations between Indigenous peoples and the Australian state.

An overview of the import of disjunctivism to the problem of radical scepticism is offered. In particular, the disjunctivist account of perceptual experience is set out, along with the manner in which it intersects with related positions such as naïve realism and intentionalism, and it is shown how this account can be used to a motivate an anti-sceptical proposal. In addition, a variety of disjunctivism known as epistemological disjunctivism is described, and it is explained how this proposal offers a further (...) way of responding to radical scepticism.

I can be aware of myself, and thereby come to know things about myself, in a variety of different ways. But is there some special way in which I—and only I—can learn about myself?

They deny that the self shows up in experience. However, in this paper I appeal to research on schizophrenia—on thought insertion, (...) in particular—to argue that Hume and his follows are wrong: The self does, in fact, show up in experience.

This paper reviews six attempts to give cooperative solutions to Prisoners Dilemmas: symmetry (agents are in identical situations, so should choose the same way, so should both choose cooperation because that’s better for each), mechanism (each agent should delegate the decision to a machine which will choose cooperation for them provided the other does likewise), inducement (the agents should make a side bet which pays off only upon both cooperating), resolution (each agent should resolve to cooperate, then act on the (...) resolution), alternative principle (rationality requires not dominance reasoning and so defecting, but constrained maximization or resolution compliance or “sophisticated” choosing, and so cooperation), and preference revision (each agent should acquire conditional preferences to cooperate, then cooperate provided the other agent has acquired similar preferences). It distinguishes one-stage from two-stage games, as well as endogenously available solutions (ones available to agents in the circumstances of the game merely due to the nature of rationality) from solutions requiring exogenous devices. It contrasts Edward McClennen’s endogenous solution, which is some combination of resolution and alternative principle solution, with David Gauthier’s endogenous alternative principle solution. It argues that all have problems, ones best solved by the endogenous preference revision solution defended by Duncan MacIntosh. (shrink)

“We are animals.” That’s what animalists say—that’s their slogan. But what animalists mean by their slogan varies. Many animalists are adamant that what they mean—and, indeed, what the true animalist thesis is—is that we are identical to animals (human animals, to be precise). But others say that’s not enough. They say that the animalist thesis has to be something more—perhaps that we are essentially or most fundamentally human animals. This paper argues that, depending on how we understand it, animalism is (...) either false or uninteresting. If animalism is just the claim that we are identical to animals, then it is uninteresting. For it doesn’t provide an answer to the question it’s meant to address. On the other hand, if animalism entails a stronger claim, such as that we are essentially animals, then animalism is false. Either way, we should set animalism aside. (shrink)

The Ashgate Research Companion to Multiculturalism brings together a collection of new essays by leading and emerging scholars in the humanities and social sciences on some of the key issues facing multiculturalism today. It provides a comprehensive and cutting-edge treatment of this important and hotly contested field, offering scholars and students a clear account of the leading theories and critiques of multiculturalism that have developed over the past twenty-five years, as well as a sense of the challenges facing multiculturalism in (...) the future. Key leading scholars, including James Bohman, Barbara Arneil, Avigail Eisenberg, Ghassan Hage, and Paul Patton, discuss multiculturalism in different cultural and national contexts and across a range of disciplinary approaches. In addition to contributions, Duncan Ivison also provides a comprehensive Introduction which surveys the field and offers an extensive guide to further reading. (shrink)

In a world no longer centered on the West, what should political theory become? Although Western intellectual traditions continue to dominate academic journals and course syllabi in political theory, up-and-coming contributions of “comparative political theory” are rapidly transforming the field. Deparochializing Political Theory creates a space for conversation among leading scholars who differ widely in their approaches to political theory. These scholars converge on the belief that we bear a collective responsibility to engage and support the transformation of political theory. (...) In these exchanges, “deparochializing” political theory emerges as an intellectual, educational, and political practice that cuts across methodological approaches. Because it is also an intergenerational project, this book presses us to reimagine our teaching and curriculum design. Bearing the marks of its beginnings in East Asia, Deparochializing Political Theory seeks to decenter Western thought and explore the evolving tasks of political theory in an age of global modernity.
