This volume collects a set of papers that were presented at a conference on “Big Questions in Free Will,” held at the University of Saint Thomas in October of 2014. It is dedicated to its editor, who passed away shortly after completing the manuscript. I will briefly summarize each of the 11 chapters and then offer a few critical comments.

Much of the debate about the mathematical refutation of Zeno’s paradoxes surrounds the logical possibility of completing supertasks—tasks made up of an infinite number of subtasks. Max Black and J.F. Thomson attempt to show that supertasks entail logical contradictions, but their arguments come up short. In this paper, I take a different approach to the mathematical refutations. I argue that even if supertasks are possible, we do not have a non-question-begging reason to think that Achilles’ supertask is possible. The justification (...) for the possibility of Achilles’ supertask lies in the possibility of him completing other supertasks of the same kind, and the justification for the possibility of him completing these other supertasks lies in the possibility of him completing yet more supertasks ad infinitum.

In this book review I argue that, broadly speaking, there are three rival accounts of the relationship between having a normative reason to act and being motivated to act. Neo-Humeans argue that an agent has a normative reason to act if and only if so doing would satisfy some desire of the agent; consequently, their task is to show that there is an internal relation between an agent’s having a normative reason to act and an agent’s having a desire to (...) act. Kantians argue that any agent who has a normative reason to act, and who is practically rational (i.e., not suffering from some debilitating form of practical irrationality, such as weakness of will or depression), will act; consequently, their task is to show that normative reasons always have overriding authority and that it is always irrational not to act upon them. Neo-Aristotelians argue that normative reasons for action are derived from facts about human well-being, and that an agent will be motivated to act provided that she has been habituated into having desires, guided by reason, to act for her own well-being; consequently, their task is to show how normative reasons can be derived from facts about human well-being and whether it is always in an agent’s best interest to act morally.

Interpreters have found it exceedingly difficult to understand how Hume could be right in claiming that his two definitions of ‘cause’ are essentially the same. As J. A. Robinson points out, the definitions do not even seem to be extensionally equivalent. Don Garrett offers an influential solution to this interpretative problem, one that attributes to Hume the reliance on an ideal observer. I argue that the theoretical need for an ideal observer stems from an idealized concept of definition, which (...) many interpreters, including Garrett, attribute to Hume. I argue that this idealized concept of definition indeed demands an unlimited or infinite ideal observer. But there is substantial textual evidence indicating that Hume disallows the employment of idealizations in general in the sciences. Thus Hume would reject the idealized concept of definition and its corresponding ideal observer. I then put forward an expert-relative reading of Hume’s definitions of ‘cause’, which also renders both definitions extensionally equivalent. On the expert-relative reading, the meaning of ‘cause’ changes with better observations and experiments, but it also allows Humean definitions to play important roles within our normative practices. Finally, I consider and reject Henry Allison’s argument that idealized definitions and their corresponding infinite minds are necessary for expert reflection on the limitations of current science.

Public arguments can be good or bad not only as a matter of logic, but also in the sense that speakers can _do_ good or bad things with arguments. For example, hate speakers use public arguments to contribute to the subordination of their targets. But how can ordinary speakers acquire the authority to perform subordinating speech acts? This is the ‘Authority Problem’. This paper defends a solution inspired by McGowan’s (Australas J Philos 87:389–407, 2009) analysis of oppressive speech, including (...) against concerns raised by McGowan (Just words: On speech and hidden harm, Oxford University Press, Oxford, 2019) herself. A _deflated_ kind of authority can be gained from the hate speaker’s standing in a norm-governed ‘activity of oppression’. We should be wary about engaging with such speakers in public argument. Even if we counter their arguments, we may still elevate their standing within that activity and so enable them to perform more pernicious speech acts than was previously possible. (shrink)

REPRODUÇÃO EM NOVILHAS LEITEIRAS -/- INTRODUÇÃO -/- O principal objetivo da criação de substitutos em gado leiteiro é produzir uma novilha que tenha seu parto aos dois anos de idade (23 a 25 meses) e com um peso de 550 a 580 kg. O manejo reprodutivo das novilhas começa quando estas atingem 14 ou 15 meses de idade e um peso de 350 a 370 kg. A produção de novilhas deve ser suficiente para substituir as vacas descartadas anualmente (25 a (...) 35%), e para contribuir com o crescimento do rebanho. Espera-se que em um gado leiteiro deva haver uma população de animais de reposição, desde um dia de vida até à fase de novilha ao parto, correspondendo pelo menos a 70 % do total das vacas (figura 1). -/- Figura 1: A meta do programa de produção de substitutos ou fêmeas de reposição consiste em uma novilha que chegue ao seu primeiro parto aos 24 ou 25 meses de idade, entre um peso de 550 a 580 kg. Elaborado pelo autor. -/- A produção de novilhas depende basicamente de três fatores: da fertilidade das vacas, ou seja, do número de bezerras nascidas anualmente; da mortalidade durante a criação e desenvolvimento; e da eficiência reprodutiva das novilhas. O manejo reprodutivo moderno das novilhas é orientado para a utilização da inseminação artificial, seja em um estro natural ou sincronizado. As novilhas representam a população animal geneticamente mais avançada no rebanho, portanto, o mérito genético de suas crias obtidas por inseminação é maior do que o das crias das vacas adultas. Além disso, as crias das novilhas obtidas mediante a inseminação aceleram o avanço genético, uma vez que contribuem com uma proporção maior de substituições do rebanho em comparação com as crias das vacas de outras faixas etárias. Além disso, as novilhas são as fêmeas mais férteis do rebanho (porcentagem de concepção: 60 a 70% vs 30 a 40% em vacas), pelo que o custo do sêmen por gestação é menor em comparação com as vacas adultas, o que permite investir em melhores touros e em sêmen sexado. -/- 1. PUBERDADE -/- A puberdade é definida como a fase de desenvolvimento em que a fêmea apresenta o seu primeiro estro fértil. Regularmente as novilhas leiteiras, sob condições ótimas de manejo, chegam à puberdade entre 11 e 12 meses de idade, ou seja, antes de alavancar o peso recomendado para receber o primeiro serviço. Vale salientar que as novilhas podem ficar gestantes após a puberdade; no entanto, isto não é conveniente porque ainda não completou-se o seu desenvolvimento. Se ficarem gestantes nos primeiros ciclos estrais, as novilhas poderiam chegar ao parto com pouco desenvolvimento físico, o que provocaria distocias e baixa produção de leite (figura 2). A ativação do sistema neuroendócrino para que a bezerra atinja a puberdade é regulada principalmente pelo estado nutricional (condição corporal). A transição do anestro pré-puberal à ciclicidade puberal coincide com um aumento da condição corporal e das concentrações de insulina, IGF-I e leptina. Estes hormônios agem como sinais metabólicos no hipotálamo e hipófise que modificam a frequência de secreção das gonadotropinas, resultando na maturação folicular e ovulação. O atraso em relação à puberdade está diretamente relacionado com deficiências na alimentação; esta condição verifica-se em criações pouco tecnificadas, principalmente de pequenos e médios produtores. As novilhas que já atingiram o peso para receber o primeiro serviço e não apresentaram estro, devem ser examinadas por via retal para excluir possíveis anormalidades do desenvolvimento, tais como freemartinismo ou hipoplasia genital. -/- Figura 2: O fator mais importante que determina a puberdade é a nutrição. Bezerras bem alimentadas apresentam ciclos estrais aos 11 meses de idade e devem ser inseminadas aos 14 ou 15 meses de idade, com um peso de 350 a 370 kg. Acervo pessoal do autor. -/- 2. DETECÇÃO DE ESTRO E INSEMINAÇÃO ARTIFICIAL -/- A baixa eficiência na detecção de estros é o problema que mais afeta a eficiência reprodutiva das novilhas. De acordo com a duração do estro (8 a 18 horas), a observação das novilhas em períodos de 30 minutos durante a manhã e à tarde, permite detectar em estro até 70% das fêmeas, enquanto a observação contínua (24 horas) aumenta a eficiência na detecção até 95% (figuras 3 e 4). No manejo tradicional dos rebanhos leiteiros, as novilhas recebem pouca atenção por parte dos trabalhadores, o que resulta em baixa eficiência na detecção de estros (50 a 60%). Em diferença das vacas adultas em lactação, as novilhas estão menos expostas a fatores que diminuem a expressão do estro, portanto, com uma rotina de observação, de pelo menos duas horas na manhã (6h a 8h da manhã) e duas horas pela tarde até a noite (17h da tarde a 19h da noite), pode-se detectar até 90% das fêmeas no estro (figura 5). -/- Figura 3: O fator que mais influencia a idade ao primeiro parto é a baixa eficiência na detecção de estros, pelo que é recomendável a observação de estros com pessoal qualificado, em períodos de pelo menos duas horas pela manhã e duas à tarde. Acervo pessoal do autor. -/- Figura 4: Com a observação contínua é possível alcançar de 90 a 95% de eficiência na detecção de estros. Acervo pessoal do autor. -/- Figura 5: A inseminação deve ser realizada durante o período de receptividade sexual. Com boa eficiência na detecção de estros, a inseminação pode ser praticada no programa AM-PM e PM-AM, ou em apenas um turno de inseminação pela manhã (10:00), com bons resultados. -/- 3. TAXA DE PRENHEZ -/- O melhor indicador de eficiência reprodutiva é a taxa de prenhez. Este indicador refere-se à proporção de animais gestantes do total elegível para inseminação, num período equivalente a um ciclo estral. Como já se descreveu no trabalho Fisiologia do Estro e do Serviço na Reprodução Bovina, este indicador considera a eficiência na detecção de estros e a porcentagem de concepção, e reflete com maior objetividade a eficácia do manejo reprodutivo. Este parâmetro pode ser melhorado através de um aumento da proporção de novilhas detectadas em estro, o que se obtém aumentando o tempo de observação e aplicando técnicas de sincronização do estro (figura 6). -/- 4. INSEMINAÇÃO DE NOVILHAS COM SÊMEN SEXADO -/- A utilização de sêmen sexado é uma boa opção para a produção de novilhas de reposição. Com a nova tecnologia disponível para a separação de espermatozoides com o cromossomo x, é possível alcançar até 90% de crias fêmeas; no entanto, o processo de separação de espermatozoides tem baixa eficiência, o que limita o número de espermatozoides por palheta. As palhetas de inseminação com sêmen sexado contém de dois a três milhões de espermatozoides (doses de sêmen não sexado têm de 20 a 30 milhões). De acordo com os dados de fertilidade de gados comerciais, as novilhas inseminadas com sêmen sexado mostram de 10 a 20% menor concepção que novilhas inseminadas com sêmen não sexado, o que desencoraja o seu uso. Causas de baixa fertilidade não são conhecidas, no entanto, estão associadas com a menor concentração espermática e com alguns danos nos espermatozoides provocados pelo processo de separação. No entanto, o uso de sêmen sexado é uma opção viável para aumentar a produção de novilhas no rebanho, e com o melhoramento dos processos de separação espermática em pouco tempo se converterá em uma prática de rotina nos estábulos (figura 7). -/- Figura 6: Uma técnica que aumenta a eficiência na detecção dos estros consiste em pintar a região da grupa. Quando esta pintura desaparece ou se nota que as novilhas estão "talhadas", devem ser apalpadas via retal para determinar se existem sinais genitais de estro. Acervo pessoal do autor. -/- Figura 7: As novilhas são as fêmeas mais férteis do rebanho, por isso o custo do sêmen por gestação é menor em comparação com as vacas adultas, o que permite investir em melhores touros e em sêmen sexado. Acervo pessoal do autor. 5. MONTA DIRIGIDA -/- A monta dirigida ou direta é uma opção prática e eficaz para emprenhar as novilhas. Neste sistema se introduz um touro com um grupo de novilhas, para que ele se encarregue de encontrar as fêmeas em estro e proceder a monta. Em rebanhos comerciais, o ideal é a utilização de um touro para 25 fêmeas. No entanto, com este manejo perde-se a oportunidade de utilizar a inseminação artificial e, com isso, a possibilidade de melhoria genética. -/- 6. PROGRAMAS DE SINCRONIZAÇÃO DE ESTROS -/- Os tratamentos para sincronizar o estro das novilhas possuem os mesmos fundamentos que os utilizados nas vacas. -/- 6.1 Prostaglandina F2a -/- A PGF2α é utilizada para a sincronização de estros em grupos de novilhas, e também é utilizada para a indução do estro individualmente, nas fêmeas que são examinadas por via retal e têm um corpo lúteo. A resposta dos animais tratados é variável; em novilhas pode-se alcançar até 95% de animais em estro. O tempo de manifestação do estro após a injeção é de 48 a 120 horas. -/- 6.1.1 Dupla injeção de PGF2a -/- Além da sincronização dos animais selecionados pela presença de um corpo lúteo diagnosticado por palpação retal, existem dois programas que não incluem a palpação retal. Por exemplo, na segunda-feira, ou no dia preferido, injeta-se PGF2α em todas as novilhas que se deseja inseminar. Cerca de 50% das novilhas manifestarão estro nas próximas 48 a 120 horas. As fêmeas que não mostrarem estro receberão uma segunda injeção na segunda-feira seguinte (intervalo de sete dias). As que apresentaram estro com a primeira injeção teriam um corpo lúteo nesse momento, enquanto as que não o manifestaram estavam em estro ou em metaestro; assim, ao repetir o tratamento sete dias depois, estas últimas novilhas teriam um corpo lúteo e responderiam à PGF2α (figura 8). No outro programa, é administrada duas doses de PGF2α com 11 dias de separação/intervalo. As novilhas podem ser inseminadas no estro observado, após qualquer uma das duas injeções. Este programa oferece uma boa sincroniza- ção após a segunda injeção e é o programa de escolha na sincronização das novilhas receptoras de embriões (figura 9). -/- Figura 8: Sincronização do estro com dupla injeção de PGF2a com 7 dias de diferença/intervalo. Elaborado pelo autor. -/- Figura 9: Sincronização do estro com dupla injeção de PGF2a com 11 dias de diferença/intervalo. Elaborado pelo autor. -/- 6.2 Progestágenos -/- Existe um tratamento que consiste na inserção, na parte externa da orelha, de um implante que contém norgestomet, que permanece na região auricular por nove dias. Além disso, o tratamento é complementado com a injeção intramuscular de valerato de estradiol e norgestomet, no momento da colocação do implante. O tempo de apresentação do estro a partir da remoção do implante é de 48 a 72 horas e a proporção de animais em estro muitas vezes se torna maior do que 80%. Outro tratamento é baseado na inserção intravaginal de dispositivos de liberação de progesterona. O dispositivo pode ser utilizado durante 12 dias ou o período de exposição pode ser encurtado, desde que seja acompanhado da injeção de uma dose luteolítica de PGF2α, um dia antes ou no momento da remoção do dispositivo. A fertilidade global conseguida após o serviço no estro sincronizado é similar à obtida no estro natural; porém, algumas novilhas são menos férteis, o que está associado com alterações no desenvolvimento folicular e alterações na relação temporal entre o estro e a ovulação. Observou-se que o tratamento com implantes de norgestomet combinados com a injeção de valerato de estradiol pode induzir comportamento estral em animais que não estão ciclando normalmente. Isso ocorre porque os níveis de estradiol, administrados no primeiro dia, persistem até o momento da remoção do implante. Assim, ao remover a fonte do progestágeno e ao haver concentrações altas de estradiol se desencadeia o estro, o qual em novilhas anéstricas não é acompanhado de ovulação, enquanto que em novilhas ciclando se altera a relação temporal entre o estro, pico pré-ovulatório de LH e ovulação. Bons resultados são alcançados quando o valerato de estradiol não é administrado e é substituído por uma injeção de PGF2α no momento da remoção do implante. Outro fator que tem sido associado com baixa fertilidade é o dia do ciclo em que o tratamento começa. Observou-se que quando coincide com a presença de um corpo lúteo (diestro), a porcentagem de concepção é maior do que quando não há um corpo lúteo (proestro). Isto ocorre porque a concentração sérica do progestágeno, por si só, não é capaz de suprimir a secreção pulsátil de LH, o que faz com que o folículo dominante presente no momento de iniciar o tratamento não sofra atresia e persista até o dia da retirada do progestágeno, convertendo-se no folículo ovulatório. Com isso, o folículo já envelheceu e o ovócito já sofreu alterações que reduzem o seu potencial para desenvolver um embrião viável. Quando o tratamento coincide com a presença de um corpo lúteo, a secreção de LH é efetivamente suprimida devido ao efeito aditivo da progesterona secretada pelo corpo lúteo e do progestágeno exógeno, inserido na vaca, o que provoca a reposição folicular. Em condições de campo, a seleção das vacas pela presença de um corpo lúteo antes de iniciar o tratamento com progestágenos é impraticável, uma vez que não é possível visualizá-lo, além disso essa prática/seleção não faria sentido, já que seria mais fácil tratar estes animais com dose ou doses de PGF2α. Atualmente existem tratamentos para eliminar folículos dominantes e promover uma nova onda folicular. -/- 6.3 Progestágenos orais -/- O acetato de melengestrol (MGA) é um progestágeno administrado por via oral. Em fêmeas bovinas é utilizado para melhorar a eficiência alimentar nos currais de engorda, o que se consegue através da inibição da apresentação do estro. Como todos os progestágenos, o MGA inibe a secreção de LH, eliminando assim a maturação do folículo e a ovulação. Após a remoção do MGA, o folículo dominante termina o seu desenvolvimento e as fêmeas apresentam estro em forma sincronizada. A dose de MGA por novilha é de 0,5 a 1 mg por dia, em tratamentos que variam de 9 a 14 dias. A apresentação comercial de MGA contém 0,22 mg do hormônio por 1 g do produto. O MGA pode ser facilmente misturado com qualquer concentrado ou grão moído. Após o último dia de tratamento, o estro se apresenta de dois a seis dias. O intervalo de remoção do MGA ao estro é mais longo quando comparado com outros progestágenos. Isto deve-se ao tempo de remoção do MGA, uma vez que enquanto um implante ou dispositivo intravaginal é removido abruptamente, o MGA pode continuar a ser absorvido enquanto é removido do trato gastrointestinal. Com tratamentos de 14 dias podem-se obter porcentagens de concepção menores em comparação com o estro natural, o que se deve em grande parte à ovulação de folículos persistentes. Um tratamento eficaz, que também melhora a fertilidade, consiste na administração de MGA durante 14 dias, seguido de uma injeção de PGF2α 15 ou 17 dias após a remoção do progestágeno. Com este programa, uma alta proporção de fêmeas teriam um corpo lúteo no momento da injeção da PGF2α e apresentariam estro com boa sincronização. Outro tratamento eficaz consiste na administração do MGA durante nove dias, mais uma dose de PGF2α ao nono dia; com este programa também se obtêm bons resultados em sincronização do estro e fertilidade. Este tratamento foi avaliado com novilhas holandesas e a porcentagem de fêmeas sincronizadas é elevada (95%). A porcentagem de concepção é semelhante à obtida no estro natural. Estes resultados são comparáveis aos obtidos com outros programas, como implantes de norgestomet ou dispositivos intravaginais de liberação de progesterona, mas com um custo significativamente menor (figura 10). -/- 6.4 Sincronização da ovulação e inseminação em tempo fixo -/- Em contraste com o observado em vacas em lactação, a resposta das novilhas aos programas de sincronização da ovulação e inseminação a tempo fixo é deficiente, o que se reflete em porcentagens de concepção de 20 a 35% menores que as novilhas inseminadas no estro natural. A causa desta resposta está relacionada com diferenças no desenvolvimento folicular; assim, nas novilhas o tempo de desenvolvimento do folículo dominante é mais rápido e o tempo de domínio é mais curto do que nas vacas em lactação. Desta forma, o folículo da onda folicular sincronizada com a injeção de GnRH sofre atresia antes da injeção de PGF2α, de tal forma que quando se induz a ovulação com a segunda injeção de GnRH, as novilhas têm folículos em diferentes estádios de desenvolvimento, o que provoca assincronia entre a ovulação e a inseminação artificial. -/- Figura 10: Programa de sincronização do estro com Acetato de Melengestrol (MGA). Elaborado pelo autor. -/- 7. MANEJO DO ANESTRO -/- Uma vez que as novilhas atingem a puberdade, apresentam ciclos estrais em intervalos de 21 dias que só são interrompidos pela gestação ou por alguma patologia. O anestro patológico é raro em novilhas; no entanto, surgem casos de piometra e cistos luteinizados, que são tratados com uma dose de PGF2α. Também se observam anormalidades de desenvolvimen- to, tais como freemartinismo e hipoplasia genital, patologias que não têm tratamento; somente 8% das novilhas freemartin são férteis. O anestro funcional (as novilhas manifestam estro, mas não são detectadas) é frequen- te e está diretamente relacionado com a eficiência na detecção de estros. As novilhas com idade e peso para se integrarem no programa reprodutivo e não apresentarem sinais de estro devem ser examinadas retalmente para diagnosticar a causa do anestro. Se, durante a palpação retal, as novilhas tiverem um corpo lúteo são tratadas nesse momento com PGF2α, os animais sem corpo lúteo podem receber uma injeção de PGF2α, sete dias depois. Este programa sincroniza o estro e aumenta a probabilidade de o detectar (figura 11). -/- Figura 11: As novilhas com idade e peso para se integrarem no programa reprodutivo e não mostrarem sinais de estro devem ser verificadas via retal para diagnosticar a causa do anestro. Arquivo pessoal do autor. -/- 8. MANEJO DA NOVILHA INFÉRTIL -/- A fertilidade das vacas leiteiras diminuiu nos últimos 30 anos, enquanto a fertilidade das novilhas não se alterou; após a primeira inseminação, entre 60 e 70% das novilhas emprenham. O objetivo do programa reprodutivo é conseguir que 90% das novilhas gestem nos primeiros três serviços. Desta forma, esta proporção de animais daria à luz antes dos 25 meses de idade. É comum que 10% das novilhas se transformem em animais repetidores, ou seja, novilhas com mais de três serviços inférteis. A causa da falha na concepção de novilhas deve-se principalmente à morte embrionária precoce. Uma causa importante da falha na concepção das novilhas repetidoras são as patologias adquiridas no aparelho reprodutivo; é comum encontrar aderências ovarianas e salpingite. Provavelmente, esses problemas são consequência de alguma infecção adquirida durante a criação. Diversos tratamentos hormonais têm sido testados para resolver o problema de infertilidade em novilhas repetidoras e os resultados obtidos ainda são deficientes. Como estes tratamentos não apresentam resultados consistentes, a melhor forma de mitigar o problema de infertilidade nas novilhas é melhorando as práticas de inseminação, ou seja, o momento da inseminação, o manejo do sêmen e a técnica de inseminação empregada. Além disso, a melhor técnica para aumentar a proporção de novilhas prenhes no rebanho é aumentar a eficiência da detecção de estros. -/- 9. RESUMO -/- As novilhas devem parir aos dois anos de idade (23 a 25 meses). O peso ao parto deve ser de 550 a 580 kg. O manejo reprodutivo começa aos 14 ou 15 meses de idade, com um peso de 350 a 370 kg. As palhetas de sêmen sexado contêm de 2 a 3 milhões de espermatozoides. As doses de sêmen não sexado contêm de 20 a 30 milhões de espermatozoides. A porcentagem de concepção das novilhas inseminadas com sêmen sexado é 10 a 20% menor do que com sêmen não sexado. Com sêmen sexado se obtém entre 90 e 95% de fêmeas. A porcentagem de concepção com programas de IATF é de 20 a 35% menor que nas novilhas inseminadas no estro natural. Cerca de 90% das novilhas devem ficar prenhes nos primeiros três serviços. Devem ser produzidas novilhas para substituir as vacas que são descartadas anualmen- te (25 a 35%). Espera-se que um gado leiteiro tenha ao dispor uma população de animais de reposição, desde um dia de vida até a etapa de novilha ao parto, correspondente a, pelo menos, 70 % do total das vacas. -/- REFERÊNCIAS BIBLIOGRÁFICAS -/- AUAD, Alexander Machado et al.

Husserl introduces a phenomenological concept called “motivation” early in the First Investigation of his magnum opus, the Logical Investigations. The importance of this concept has been overlooked since Husserl passes over it rather quickly on his way to an analysis of the meaningful nature of expression. I argue, however, that motivation is essential to Husserl’s overall project, even if it is not essen- tial for defining expression in the First Investigation. For Husserl, motivation is a relation between mental acts whereby (...) the content of one act make some fur- ther meaningful content probable. I explicate the nature of this relation in terms of “evidentiary weight” and differentiate it from Husserl’s notion of Evidenz, often translated as “self-evidence”. I elucidate the importance of motivation in Husserl’s overall phenomenological project by focusing on his analyses of thing-perception and empathy. Through these examples, we can better understand the continuity between the Logical Investigations and Husserl’s later work. (shrink)

This paper aims to assess knowledge management maturity at HEI to determine the most effecting variables on knowledge management that enhance the total performance of the organization. This study was applied on Al-Azhar University in Gaza strip, Palestine. This paper depends on Asian productivity organization model that used to assess KM maturity. Second dimension assess high performance was developed by the authors. The controlled sample was (364). Several statistical tools were used for data analysis and hypotheses testing, including reliability Correlation (...) using Cronbach’s alpha, “ANOVA”, Simple Linear Regression and Step Wise Regression. The overall findings of the current study suggest that KMM is suitable for measuring and lead to enhance high performance. KMM assessment shows that the university maturity level is in level three. Findings also support the main hypothesis and it is subhypotheses. The most important factors effecting high performance are: Processes, KM leadership, People, KM Outcomes, Knowledge Process. Furthermore the current study is unique by the virtue of its nature, scope and way of implied investigation, as it is the first study at HEI in Palestine explores the status of KMM using the Asian productivity model.

The current study tries to verify the effectiveness of a training program in increasing Crowdfunding awareness. The sample was (50) students in CIS, who were purposively selected and distributed equally into a treatment and control group. The researchers designed the study tools (a training program to increase Crowdfunding awareness). The study findings revealed the existence of statistically significant differences between the treatment and control groups in favor of the former. Furthermore, there were statistically significant differences between the pre and the (...) post measures of the treatment group in favor of the post measures. Furthermore the current study is unique by the virtue of its nature, scope and way of implied investigation, as it is the first study for Crowdfunding training program in Arabic world. (shrink)

Weak particularism about reasons is the view that the normative valency of some descriptive considerations varies, while others have an invariant normative valency. A defence of this view needs to respond to arguments that a consideration cannot count in favour of any action unless it counts in favour of every action. But it cannot resort to a global holism about reasons, if it claims that there are some examples of invariant valency. This paper argues for weak particularism, and presents a (...) framework for understanding the relationships between practical reasons. A central part of this framework is the idea that there is an important kind of reason-a 'presumptive reason'-which need not be conclusive, but which is neither pro tanto nor prima facie. /// [Richard Holton] Should particularists about ethics claim that moral principles are never true? Or should they rather claim that any finite set of principles will not be sufficient to capture ethics? This paper explores and defends the possibility of embracing the second of these claims whilst rejecting the first, a position termed 'principled particularism'. The main argument that particularists present for their position-the argument that holds that any moral conclusion can be superseded by further considerations-is quite compatible with principled particularism; indeed, it is compatible with the idea that every true moral conclusion can be shown to follow deductively from a finite set of premises. Whilst it is true that these premises must contain implicit ceteris paribus clauses, this does not render the arguments trivial. On the contrary, they can do important work in justifying moral conclusions. Finally the approach is briefly applied to the related field of jurisprudence. (shrink)

Temporal discounting is a technical operation in climate change economics. When discount rates are positive, economic evaluation treats future benefits as less important than equivalent present benefits. This chapter explains and critically evaluates four different reasons economists have given for tying discount rates to the interest rates we observe in real-world markets. I suggest that while philosophers have correctly criticized three of these reasons, their criticisms of the fourth miss the mark. This is because philosophers have not taken heed of (...) the distinct analytical framework in which the fourth reason arises. (shrink)

Local miracle compatibilists claim that we are sometimes able to do otherwise than we actually do, even if causal determinism obtains. When we can do otherwise, it will often be true that if we were to do otherwise, then an actual law of nature would not have been a law of nature. Nevertheless, it is a compatibilist principle that we cannot do anything that would be or cause an event that violates the laws of nature. Carl Ginet challenges this nomological (...) principle, arguing that it is not always capable of explaining our inability to do otherwise. In response to this challenge, I point out that this principle is part of a defense against the charge that local miracle compatibilists are committed to outlandish claims. Thus it is not surprising that the principle, by itself, will often fail to explain our inability to do otherwise. I then suggest that in many situations in which we are unable to do otherwise, this can be explained by the compatibilist’s analysis of ability, or his criteria for the truth of ability claims. Thus, the failure of his nomological principle to explain the falsity of certain ability claims is no strike against local miracle compatibilism. (shrink)

There are kinds of dialogue that support social justice and others that do the reverse. The kinds of dialogue that support social justice require that anger be bracketed and that hiding in safe spaces be eschewed. All illegitimate ad hominem/ad feminem attacks are ruled out from the get-go. No dialogical contribution can be down-graded on account of the communicator’s gender, race, or religion. As well, this communicative approach unapologetically privileges reason in full view of theories and strategies that might seek (...) to undermine reasoning as just another illegitimate form of power. On the more positive side, it is argued in this paper that social justice dialogue will be enhanced by a kind of “communicative upgrading,” which amplifies “person perception,” foregrounds the impersonal forces within our common social spaces rather than the “baddies” within, and orients the dialogical trajectory toward the future rather than the past. Finally, it is argued in this paper that educators have a pressing responsibility to guide their students through social justice dialogue so that their speech contributes to the amelioration of injustice, rather than rendering the terrain more treacherous.

Michael J. Almeida presents a bold new defence of the existence of God. He argues that entrenched principles in philosophical theology which have served as basic assumptions in apriori, atheological arguments are in fact philosophical dogmas. Almeida argues that not only are such principles false - they are necessarily false.

We take ourselves to have an inner life of thought, and we take ourselves to be capable of linguistically expressing our thoughts to others. But what is the nature of this “inner life” of thought? Is conscious thought necessarily carried out in language? This paper takes up these questions by examining Merleau-Ponty’s theory of expression. For Merleau-Ponty, language expresses thought. Thus it would seem that thought must be independent of, and in some sense prior to, the speech that expresses it. (...) He also claims, however, that thinking just is linguistic expression, and thus that language constitutes thought. The primary aim of this paper is to make sense of this constitutive claim while maintaining that, for Merleau-Ponty, there is an inner life of thought that exists independently of linguistic expression, and that this inner life rightly deserves the label “thought”. The upshot of this account is twofold. First, it explains why the mainstream view of Merleau-Ponty’s theory of expression seems plausible, but is ultimately inadequate. Second, it functions as a corrective to contemporary debates about the nature and scope of phenomenal consciousness and the sense in which conscious experience has content. (shrink)

Ever since the hard problem of consciousness (Chalmers, 1996, 1995) first entered the scene in the debate over consciousness many have taken it to show the limitations of a scientific or naturalist explanation of consciousness. The hard problem is the problem of explaining why there is any experience associated with certain physical processes, that is, why there is anything it is like associated with such physical processes? The character of one’s experience doesn’t seem to be entailed by physical processes and (...) so an explanation which can overcome such a worry must (1) explain how physical processes give rise to experience (explain the entailment), (2) give an explanation which doesn’t rely on such physical processes, or (3) show why the hard problem is misguided in some sense. Recently, a rather ambitious and novel theory of consciousness has entered the scene – Integrated Information Theory (IIT) of Consciousness (Oizumi et al., 2014; Tononi, 2008; Tononi et al., 2016) – and proposes that consciousness is the result of a specific type of information processing, what those developing the theory call integrated information. The central aim of this dissertation is to philosophically investigate IIT and see whether it has the ability to overcome the hard problem and related worries. I then aim to use this philosophical investigation to answer a set of related questions which guide this dissertation, which are the following: Is it possible to give an information-theoretic explanation of consciousness? What would the nature of such an explanation be and would it result in a novel metaphysics of consciousness? In this dissertation, I begin in chapter one by first setting up the hard problem and related arguments against the backdrop of IIT (Mindt, 2017). I show that given a certain understanding of structural and dynamical properties IIT fails to overcome the hard problem of consciousness. I go on in chapter two to argue that a deflationary account of causation is the best view for IIT to overcome the causal exclusion problem (Baxendale and Mindt, 2018). In chapter three, I explain IIT’s account of how the qualitative character of our experience arises (qualia) and what view of intentionality (the directedness of our mental states) IIT advocates. I then move on in chapter four to show why the hard problem mischaracterizes structural and dynamical properties and misses important nuances that may shed light on giving a naturalized explanation of consciousness. In the last and fifth chapter, I outline a sketch of a novel metaphysics of consciousness that takes the conjunction of Neutral Monism and Information-Theoretic Structural Realism to give what I call Information-Theoretic Neutral-Structuralism.

This paper draws attention to a fundamental problem for a version of the tracing strategy defended by a number of theorists in the current literature (Rosen 2004, Fischer and Tognazzini 2009). I argue that versions of the tracing strategy that require reasonable foreseeability are in tension with the view that blameless ignorance excuses. A stronger version of the tracing strategy is consistent with the view that blameless ignorance excuses and is therefore preferable for those tracing theorists who wish to continue (...) maintaining that it does.

Aristotle claims that in some extenuating circumstances, the correct response to the wrongdoer is sungnōmē rather than blame. Sungnōmē has a wide spectrum of meanings that include aspects of sympathy, pity, fellow-feeling, pardon, and excuse, but the dominant interpretation among scholars takes Aristotle’s meaning to correspond most closely to forgiveness. Thus, it is commonly held that the virtuous Aristotelian agent ought to forgive wrongdoers in specific extenuating circumstances. Against the more popular forgiveness interpretation, I begin by defending a positive account (...) of sungnōmē as the correct judgment that a wrongdoer deserves excuse since she was not blameworthy. I then argue that since sungnōmē is merited on the grounds of fairness, this shows that both the forgiveness interpretation and a third, alternative interpretation of sungnōmē as sympathy mischaracterize both the justification for sungnōmē and its nature. Moreover, I argue that Aristotle not only lacks an account of forgiveness but in fact, that his account of blame is incompatible with forgiveness altogether. (shrink)

Traditional views about God and about deliberation seem to imply that we need a deliberation restriction on the concept of divine omniscience. I will argue, however, that this deliberation restriction is both irrelevant and unnecessary. It is irrelevant because there is no time at which God needs to deliberate; and it is unnecessary because even if God does deliberate, it’s possible for him to do so while knowing what the results of that deliberation will be. And because this possibility of (...) deliberating despite knowing the results holds for deliberation in general, my argument provides useful (and perhaps surprising) results not only for discussions of the divine attributes, but also for broader discussions of deliberation itself.

In 'The Reference Book' (2012), Hawthorne and Manley observe the following contrast between (1) and (2): -/- (1) In every race John won. (2) In every race, the colt won. -/- The name 'John' in (1) must intuitively refer to the same single individual for each race. However, the description 'the colt' in (2) has a co-varying reading, i.e. a reading where for each race it refers to a different colt. This observation is a prima facie problem for proponents of (...) so-called The-Predicativism which is the view that the name in (1) is really a covert definite description, viz. 'the John'. If the The-Predicativism is correct, (1) and (2) are therefore syntactically equivalent, but this makes it mysterious why only (2) would have a co-varying reading. In a recent paper, Fara (2015) argues that there is a simple and elegant way for proponents of The-Predicativism to explain this contrast. This explanation relies on discerning some subtle syntactic differences between (1) and (2) which in turn are based on assumptions about nominal restrictions a la Stanley and Szabó (2000). In this short paper, I demonstrate that Fara's proposed explanation has a variety of serious shortcomings and hence that the contrast between (1) and (2) remains a significant problem for Predicativism.

The Ockhamist claims that our ability to do otherwise is not endangered by God’s foreknowledge because facts about God’s past beliefs regarding future contingents are soft facts about the past—i.e., temporally relational facts that depend in some sense on what happens in the future. But if our freedom, given God’s foreknowledge, requires altering some fact about the past that is clearly a hard fact, then Ockhamism fails even if facts about God’s past beliefs are soft. Recent opponents of Ockhamism, including (...) David Widerker and Peter van Inwagen, have argued along precisely these lines. Their arguments, if successful, would undermine Ockhamism while avoiding the controversy over the alleged softness of facts about God’s past beliefs. But these arguments do not succeed. The past facts they rely on must be clear and uncontroversial examples of hard facts about the past, and these facts must be such that an ability to refrain from the relevant future action implies an ability to alter the relevant hard fact. We demonstrate the flaw in these arguments by showing how they rely on past facts that do not satisfy these criteria. The Ockhamist may have troubles, but this type of argument is not one of them.

The social cost of carbon (SCC) is a central concept in climate change economics. This chapter explains the SCC and investigates it philosophically. As is widely acknowledged, any SCC calculation requires the analyst to make choices about the infamous topic of discount rates. But to understand the nature and role of discounting, one must understand how that concept—and indeed the SCC concept itself—is yoked to the concept of a value function, whose job is to take ways the world could be (...) across indefinite timespans and to rank them from better to worse. A great deal, therefore, turns on the details of the value function and on just what is meant by “better” and “worse.” This chapter seeks to explicate these and related issues, and then to situate them within the evolving landscape of federal climate policy in the United States.

In August 2017, Google executives found themselves in a difficult position. An internal memo written by a disgruntled software engineer, James Damore, had just gone viral. In this memo, Damore claimed that the relatively small number of women in the tech industry was partly due to biological factors, and that many of Google’s diversity efforts were therefore counterproductive. The contents of this memo were offensive to many (and thus were having a negative impact on the overall workplace environment), but the (...) executives were aware that the wrong reaction to it would at least partially vindicate Damore’s claims about the lack of open discussion at Google. In the end, after two days of controversy, Google leadership decided to fire Damore on the grounds that he had violated the company’s code of conduct. This case gives students an opportunity to explore the numerous issues raised by Damore’s memo and the controversy surrounding it. Did Google handle this case properly? Was firing Damore the right thing to do? How could the situation have been handled more effectively? (shrink)

According to group-agent realism, treating groups as agents with their own intentional states, irreducible to those of the group members, helps us explain and predict the groups’ behavior. This paper challenges this view. When groups judge logically interconnected propositions, group members often have incentives to misrepresent their beliefs of propositions they care less about in order to increase the probability of their groups adopting their view of propositions they consider more important. Aggregating such untruthful judgments may lead to the group (...) forming false beliefs. Treating groups as agents will then not help us explain or predict their behavior. (shrink)

Prior research has demonstrated that antisocial behavior, substance-use disorders, and personality dimensions of aggression and impulsivity are indicators of a highly heritable underlying dimension of risk, labeled externalizing. Other work has shown that individual trait constructs within this psychopathology spectrum are associated with reduced self-monitoring, as reflected by amplitude of the error-related negativity (ERN) brain response. In this study of undergraduate subjects, reduced ERN amplitude was associated with higher scores on a self-report measure of the broad externalizing construct that links (...) these various indicators. In addition, the ERN was associated with a response-locked increase in anterior theta (4–7 Hz) oscillation; like the ERN, this theta response to errors was reduced among high-externalizing individuals. These findings suggest that neurobiologically based deficits in endogenous action monitoring may underlie generalized risk for an array of impulse-control problems. (shrink)

This paper explores religious belief in connection with epistemological disjunctivism. It applies recent advances in epistemological disjunctivism to the religious case for displaying an attractive model of specifically Christian religious belief. What results is a heretofore unoccupied position in religious epistemology—a view I call ‘religious epistemological disjunctivism’. My general argument is that RED furnishes superior explanations for the sort of ‘grasp of the truth’ which should undergird ‘matured Christian conviction’ of religious propositions. To this end I first display the more (...) familiar perceptual epistemological disjunctivism, contrasting it with both externalist and classically internalist views. This prepares the way for introducing RED with its own distinctive factive mental state operator—pneuming that p. In this second section I present the RED model, not failing to address a potential problem concerning religious disagreement. I also clarify RED’s distinctive internalist aspect, describing how it comports with contemporary internalist thinking in epistemology. I then move in section three to criticize externalist and classical internalist views, showing where they fail to make proper sense of the sort of knowing which should ground mature Christian conviction. Specifically, I highlight three intuitions which I think any theory of religious belief should capture: what I call the case-closed intuition, the good believer intuition, and the Plantingian platitude. This is all to set up for the final section where I argue that RED is superior for understanding proper religious believing—capturing the aforementioned intuitions. (shrink)

Examining Seneca’s account of friendship produces an interpretative puzzle: if the good of the Stoic sage is already both complete and self-sufficient, how can friendship be a good? I reject the solution that friendship is simply a preferred indifferent instead of a good and argue that though Seneca’s account can consistently explain both why friendship’s nature as a good does not threaten the completeness or the self-sufficiency of the sage, Stoic friends must choose between intimate friendships that leave them vulnerable (...) or impersonal friendships that lack intimacy but do not undermine their happiness. The consistent Stoic must choose the latter, but I argue that this conflict shows why we ought to reject the Stoic model of friendship. (shrink)

This case examines the rise and fall of WeWork—a company that experienced one of the most dramatic changes of fortune in technology company history. For several years, WeWork was a Silicon Valley darling, growing at breakneck speed with visionary Adam Neumann at the helm. By some estimates, Neumann’s company was worth $47 billion in January of 2019. But when the company filed paperwork in preparation for going public later that year, investors balked at the details revealed in the documents: billions (...) of dollars in losses and lots of questionable behavior on the part of Neumann (including numerous conflicts of interest involving his personal business dealings). The IPO was postponed and later withdrawn; Neumann was forced to step down as CEO; and by May of 2020 the company’s valuation had dropped to $3 billion. Exploring this recent history will provide an opportunity to ask what lessons can be drawn from the rise and fall of WeWork, and from the economic and social context that enabled its growth.

Edwards’s views on the nature of the human will demonstrate his unique ability to unite philosophical rigor and theological fervor. Edwards was a staunch defender of the Reformed doctrines of absolute divine sovereignty and meticulous providence, but he was also a proponent of the intellectual tools and methods of early modern philosophy (and of John Locke in particular). His ultimate statement of his doctrinal position, Freedom of the Will, is the masterful result of these dual commitments.

In her article, "Thinking and Moral Considerations," Hannah Arendt provides a provocative approach to the question of evil by suggesting that banal evil-the most common kind-may arise directly from thoughtlessness. If that is so, thinking may provide an antidote to evil. Learning to think would then offer the individual and society protection against the dangers of thoughtless evil. She further suggests that thinking may clear the way for a form of judging that "when the chips are down" may turn people (...) toward right rather than wrong, beauty rather than ugliness. In this essay I address her claim by noting an example of apparently thoughtless evil, the murder of Duncan by Macbeth, and by showing how this event clarifies Arendt's thesis, including both its weaknesses and its strengths. The use of Macbeth will amount to a sketch of certain features of the play particularly relevant to this ethical issue, followed by an analysis of ways Arendt's thesis connects with the murder of Duncan.

This paper aims to determine knowledge management (KM) factors which have strong impact on high performance. Also, the study aims to compare KMM between intermediate colleges. This study was applied on three intermediate colleges in Gaza strip, Palestine. Asian productivity organization model was applied to measure KMM. Second dimension which assess high performance was developed by the authors. The controlled sample was 190. Several statistical tools were used for data analysis and hypotheses testing, including reliability correlation using Cronbach’s alpha, “ANOVA”, (...) simple linear regression and step wise regression and LSD test. The overall findings of the current study show that maturity level is in the second level. Findings also support the main hypothesis and its sub- hypotheses. The most important factors effecting high performance are the processes, KM leadership, people and KM outcomes. In addition, there are differences in high performance for college (PTC). Furthermore, the current study is unique by the virtue of its nature, scope and way of implied investigation, as it is the first comparative study between intermediate colleges in Palestine that explores the status of KMM using the Asian productivity model. Research limitations was that the survey findings were based on intermediate colleges in Gaza Strip. (shrink)

According to the argument from gratuitous evil, if God were to exist, then gratuitous evil wouldn’t; but gratuitous evil does exist, so God doesn’t. We can evaluate different views of divine providence with respect to the resources they are able to bring to bear when encountering this argument. By these lights, theological determinism is often seen as especially problematic: the determinist is seen as having an impoverished set of resources to draw from in her attempts to respond to the argument (...) from gratuitous evil. In particular, there is an important resource – an appeal to free will – that many have claimed is unavailable to the determinist. I argue that the determinist does not in fact suffer from this particular resource deficit. I do so by examining some recent work on determinist responses to the problem of evil, analyzing some of the ways in which they fall short, and proposing a new response that is informed by those shortcomings. This new response is built on an appeal to the reactive attitudes. (shrink)

Game theory involves deliberating about what to do in light of what other people are likely to do. One of the central frameworks of game theory is the prisoner’s dilemma, in which participants who make rational choices end up in suboptimal outcomes. Using the prisoner’s dilemma to model competition between firms sets the stage for a new and promising approach to business ethics: the market failures approach.

Standard ways of conceptualizing moral development and measuring pedagogical interventions in ethics classes privilege the growth of moral judgment over moral sensitivity, moral motivation, and moral habits by too often conflating improvement in moral judgment with holistic moral development. I argue here that if we care about students’ construction and cultivation of their ethical selves, our assessment design principles ought to take seriously the transformative possibilities of philosophy as a way of life and be based on a more robust and (...) holistic account of moral development. I illustrate these principles of assessment design through an examination of the Character Project, which I created to help students engage in their own deliberate ethical transformation through self-directed, individualized, and concentrated practice. Finally, I conclude with a discussion about how to appropriately and fairly assess this kind of deeply personal learning. (shrink)

Should we kill animals to save animals? This question lies at the heart of this case study. Sovereign nations have an interest in protecting and conserving their natural resources, and in particular their distinctive flora and fauna. As they seek to promote these interests, they inevitably face the economic question of how they are going to finance their conservation efforts. One way of answering this question is to engage in the practice of selling big game hunting licenses and using the (...) revenues to fund conservation programs. This strategy is counterintuitive (and to some, morally repellent); but it has a partial track record of success in places such as Namibia, South Africa, and the United States. Despite its successes, there are some who believe that the moral objections to such a strategy outweigh any potential benefits. This case study provides the student with an opportunity to explore the tension between the desire to save endangered animals and the possibility that the best way to do that involves killing some of them.

For Aristotle, some wrongdoers do not deserve blame, and the virtuous judge should extend sungnōmē, a correct judgment about what is equitable, under the appropriate excusing circumstances. Aristotle’s virtuous judge, however, does not forgive; the wrongdoer is excused from blame in the first place, rather than being forgiven precisely because she is blameworthy. Additionally, the judge does not fail to blame because she wishes to be merciful or from natural feeling, but instead, because that is the equitable action to take (...) under the circumstances. Moreover, while Aristotle does claim in his discussions of the virtues of megalopsychia and praotēs that the virtuous person will sometimes fail to become angry at blameworthy wrongdoers, Aristotle’s reasons for repudiating anger or forestalling blame have little to do with the sorts of reasons that one would or could be forgiving for. Although an Aristotelian virtuous agent does let go of anger for her own reasons, she does not forgive. As a result, I argue that since Aristotle’s account of equity entails that forgiveness is positively vicious, forgivingness is not merely a virtue left out of Aristotle’s account, but is in fact incompatible with his account.

The failure to understand the needs, beliefs, and values of others is widely blamed on a lack of empathy, which has been touted in recent years as the necessary ingredient for bringing us together and ultimately for tackling issues of social justice and harmony. In this essay, I explore whether empathy really can serve the role it has been tasked with. To answer this question, I will first identify what empathy is and why its champions believe it plays such an (...) essential role in social life. With this in mind, I contend that promoting empathy on its own may make solidarity among diverse populations more difficult to achieve and undermine social reconciliation. Instead, I argue for a different approach that begins with acknowledging our self-oriented perspective and how it shapes what we see, appreciate, and interpret, before turning to others with a kind of loving attention. Unlike empathy, loving attention allows us to see others as they really are, not as we imagine we would be in their shoes, and is that kind of perception that is necessary for bridging divides and building solidarity in our contemporary world.

In the one-for-one business model, a purchaser of, for example, a pair of shoes simultaneously purchases a pair of shoes for a child in need. This model, popularized by TOMS shoe company in 2006, has been remarkably successful. The driving force behind the success is most likely the emotional appeal of the one-for-one idea. The TOMS model has been criticized, however—not just for being less effective than advertised, but for arguably doing more harm than good. Whether or not this latter (...) charge is true, the TOMS story serves as an illustrative starting point for an exploration of the ways in which commonsense thinking about charity and philanthropy is often wrong. Examining these criticisms will set the stage for an examination of the influential “effective altruism” movement and invite the reader to think more deeply about different ways of doing good in the world.

This case (...) invites students to explore this possibility by introducing them to the facts surrounding the lawsuits and highlighting some of the most salient moral considerations. Students will also be asked to reflect on the public policy implications, if any, of their findings. (shrink)

Since Uber’s founding in 2009, individuals associated with Uber have engaged in (or been accused of engaging in) numerous categories of corporate malfeasance: failure to protect data privacy, theft of trade secrets, sexual misconduct (including sexual assault and sexual harassment), lack of worker safety, lack of consumer safety, and racial discrimination. Thus, Uber is a good test case for the question of whether corporate behavior can provide moral justification for a boycott. More specifically, an examination of the 2017 #deleteUber controversy (...) will invite the reader to consider questions such as the following: When is a personal boycott morally justified, and when (if ever) is a personal boycott morally obligatory? How are personal boycotts related to larger-scale organized boycotts? What are the factors that make an organized boycott morally justified (or unjustified)? Is there a sound argument for the conclusion that we should #deleteUber? (shrink)

Are the wishes of the dead more important than the needs of the living? This question is prompted by consideration of the Hershey Trust Company, a perpetual charitable trust that not only owns and operates the Milton Hershey School in Pennsylvania, but also owns a controlling interest in various Hershey-related for-profit entities. This unusual arrangement, and the conditions under which it was formed, have produced a situation in which a small, private boarding school for low-income students has an endowment of (...) $12 billion (in addition to its other corporate and real estate interests). The trust has been operating according to its founder’s wishes for decades, but some have wondered whether its resources could be put to better use for more urgent needs. This case will invite students to consider the question of how we should weigh the needs of the living against the wishes of the dead. (shrink)

This article challenges the view most recently expounded by Emily Jackson that ‘decisional privacy’ ought to be respected in the realm of artificial reproduction (AR). On this view, it is considered an unjust infringement of individual liberty for the state to interfere with individual or group freedom artificially to produce a child. It is our contention that a proper evaluation of AR and of the relevance of welfare will be sensitive not only to the rights of ‘commissioning parties’ to AR (...) but also to public policy considerations. We argue that AR has implications for the common good, by involving matters of human reproduction, kinship, race, parenthood and identity. In this paper we challenge presuppositions concerning decisional privacy. We examine the essential commodification of human life implicit in AR and the systematicity that makes this possible. We address the objection that it is an ethically neutral way of having children and consider the problem of ‘existential debt’. After examining objections to the thesis that AR is illegitimate for reasons of public policy and the common good, we return to the issue of decisional privacy in the light of considerations concerning the legitimate role of the state in matters affecting human reproduction.

What is involved in weighing normative reasons against each other? One attractive answer offers us the following Simple Picture: a fact is a reason for action when it bears to an action the normative relation of counting in its favour; this relation comes in different strengths or weights; the weights of the reasons for and against an action can be summed; the reasons for performing the action are sufficient when no other action is more strongly supported, overall; the reasons are (...) decisive when it is most strongly supported; one ought to perform the action there is most reason to perform; rational deliberation is weighing reasons correctly; and acting rationally is doing what one has sufficient reasons to do. This chapter investigates various ways in which, on examination, this Simple Picture appears to require modification and refinement. It examines some of the ways in which talk of the weight of a reason may need improvement, looks more closely at the relationship between reasons and rationality, and asks whether there are ways in which a reason can be defeated which are not kinds of outweighing. The conclusion is that while in some respects the Simple Picture does need to be corrected, in others the jury is out. (shrink)

Open Access: This essay argues that Claudia Card numbers among important contributors to nonideal ethical theory, and it advocates for the worth of NET. Following philosophers including Lisa Tessman and Charles Mills, the essay contends that it is important for ethical theory, and for feminist purposes, to carry forward the interrelationship that Mills identifies between nonideal theory and feminist ethics. Card's ethical theorizing assists in understanding that interrelationship. Card's philosophical work includes basic elements of NET indicated by Tessman, Mills, and (...) others, and further offers two important and neglected elements to other nonideal ethical theorists: her rejection of the “administrative point of view,” and her focus on “intolerable harms” as forms of “extreme moral stress” and obstacles to excellent ethical lives. The essay concludes that Card's insights are helpful to philosophers in developing nonideal ethical theory as a distinctive contribution to, and as a subset of, nonideal theory. (shrink)

Causalists about explanation claim that to explain an event is to provide information about the causal history of that event. Some causalists also endorse a proportionality claim, namely that one explanation is better than another insofar as it provides a greater amount of causal information. In this chapter I consider various challenges to these causalist claims. There is a common and influential formulation of the causalist requirement – the ‘Causal Process Requirement’ – that does appear vulnerable to these anti-causalist challenges, (...) but I argue that they do not give us reason to reject causalism entirely. Instead, these challenges lead us to articulate the causalist requirement in an alternative way. This alternative articulation incorporates some of the important anti-causalist insights without abandoning the explanatory necessity of causal information. For example, proponents of the ‘equilibrium challenge’ argue that the best available explanations of the behaviour of certain dynamical systems do not appear to provide any causal information. I respond that, contrary to appearances, these equilibrium explanations are fundamentally causal, and I provide a formulation of the causalist thesis that is immune to the equilibrium challenge. I then show how this formulation is also immune to the ‘epistemic challenge’ – thus vindicating (a properly formulated version of) the causalist thesis. (shrink)

Open Access: Trudy Govier (FR) argues for “conditional unforgivability,” yet avers that we should never give up on a human being. She not only says it is justifiable to take a “hopeful and respectful attitude” toward one’s wrongdoers, she indicates that it is wrong not to; she says it is objectionable to adopt an attitude that any individual is “finally irredeemable” or “could never change,” because such an attitude “anticipates and communicates the worst” (137). Govier’s recommendation to hold a hopeful (...) attitude seems to follow from one’s knowing that an appropriate object of unforgivability is also an agent capable of moral transformation. I appeal to Blake Myers-Schultz’s and Eric Schwitzgebels’ account of knowledge without belief, and Schwitzgebels’ account of attitudes, to argue that a victim’s knowledge that a wrongdoer has the capacities of a moral agent does not entail belief in the possibility that a wrongdoer will exercise those moral capacities, nor does knowledge of a wrongdoer’s moral capacities entail hopeful attitudes toward the prospects of an individual wrongdoer’s moral transformation. I conclude that what victims can hope for should not be that which victims are held to as a moral minimum. (shrink)
