La complejidad del mundo actual demanda de nuevas formas de pensar, diferentes a las convencionales. La educación exige cambios acelerados en la formación de los seres humanos. Cambios impredecibles que toman por sorpresa, quizá se está frente a una transformación en contextos geográficos, comunicación, convivencia con los ‘otros’; todo ello afectado por las transformaciones constantes. A la par de estas transformaciones, las grandes problemáticas sociales, ambientales, políticas, económicas continúan creciendo, no se logra alcanzar una sostenibilidad en el estilo de vida (...) de las sociedades. Es cierto que estamos en un mundo globalizado gracias a la Internet y a las Tecnologías de la Información y la Comunicación (TIC), por consecuente la información está al alcance de la mayoría de los seres humanos. Si el planeta está al frente de una globalización tecnológica, la educación también debe globalizarse, sin perder la identidad local. De ahí nace el desafío de reinventar los procesos de formación, direccionarlos hacia la transformación social, y al desarrollo de competencias profesionales básicas como el ‘aprender a vivir juntos’ bajo los cánones éticos que como civilización históricamente se practica.

La formación docente es indispensable para responder a los requerimientos de la compleja sociedad actual. De su conocimiento, iniciativa, praxis y creatividad depende el éxito o el fracaso del sujeto que aprende. Al modificar el rol del docente se transforma la actitud de los estudiantes. ¿Cómo entender la formación filosófica transdisciplinar? Este texto responde a este y otros cuestionamientos: ¿cuáles son los planteamientos pedagógicos afines a la era digital? ¿en qué medida las TIC se encuentran al servicio de una filosofía (...) educativa transdisciplinar?, ¿cómo se explica ese enfoque en la formación del docente?, ¿cuál es la función de la formación en la innovación educativa?, ¿cómo formar para la ciudadanía mundial?, ¿cuáles son las contribuciones de las nuevas ciencias para la formación educativa? El crecimiento exponencial de la ciencia y de la tecnología nos obliga a pensar en procesos formativos innovadores. En tal sentido, resulta imprescindible el estudio de estas problemáticas. (shrink)

La familia desde una relectura de la política de Aristóteles, elaborado por Pablo Andrés Heredia y Catya Ximena Torres Cordero, en el que se presenta un análisis de la obra de Aristóteles con la finalidad de establecer las diferencias existentes entre las percepciones clásica y moderna sobre la familia; a su vez, los autores se proponen reconocer la relevancia de la familia en la construcción de la sociedad y del Estado a partir del análisis dedos obras de la filosofía política (...) contemporánea: La condición humana de Hannah Arendt (1993) y Homo Saccer de Giorgio Agamben (1998); obras que a decir de los autores retoman, extienden el pensamiento aristotélico y establecen una serie de directrices para comprender el lugar de la familia en el ámbito público.

La investigación incorpora las experiencias de un grupo de personas artesanas de las provincias de Azuayy Cañar, en Ecuador. Tiene como objetivo reflexionar, desde un enfoque pedagógico centrado en la educaciónsocial y popular, sobre las prácticas profesionales de los colectivos artesanales y su relación con los procesosescolarizados de enseñanza y aprendizaje. El estudio aplica la metodología cualitativa con enfoque etnográfico.Los resultados no solo visibilizan que los espacios que ocupa el artesanado en el imaginario social están marcadospor bloqueos y restricciones en (...) el ejercicio profesional, también dan cuenta que los saberes que portan estáncondicionados por dimensiones étnicas y socioculturales, y que pese a contar con experiencias y conocimientosque no distan de los contenidos curriculares con los que se forma en el sistema educativo, son excluidos yconsiderados de menor valía. La investigación concluye que los métodos y procedimientos artesanales puedenser utilizados como elementos formativos potentes para fortalecer la identidad, la participación democrática,el diálogo de saberes, la justicia social y una verdadera educación intercultural. En consecuencia, la educaciónsocial y popular puede ayudar a promover la participación activa de artesanos y otros colectivos, y de esa maneracontribuir con la transformación y cambio de las estructuras desiguales desde una filosofía socioeducativa.

A inicio de los años 90 la sociedad cubana se enfrentaba a un proceso de profundas transformaciones internas como consecuencia de los cambios en la esfera de las relaciones internacionales, el recrudecimiento del bloqueo de Estados Unidos y la necesidad de insertarse en la nueva dinámica de las relaciones económicas mundiales después de desaparecida la URSS y el socialismo este-europeo. Todo ello tuvo un importante impacto en los valores de la sociedad cubana, especialmente en los jóvenes. En razón de ello, (...) la Asamblea nacional del Poder Popular convocó a una audiencia pública sobre la formación de valores en las nuevas generaciones, llevada a cabo los días 24 y 25 de abril de 1995. Este libro recoge las más importantes intervenciones presentadas desde diversos planos de análisis: filosófico (José Ramón Fabelo Corzo), histórico (Cintio Vitier), sociológico (María Isabel Domínguez), psicológico (Fernando González) y pedagógico (Gilberto García Batista).

Mimesis can refer to imitation, emulation, representation, or reenactment - and it is a concept that links together many aspects of ancient Greek Culture. The Western Greek bell-krater on the cover, for example, is painted with a scene from a phlyax play with performers imitating mythical characters drawn from poetry, which also represent collective cultural beliefs and practices. One figure is shown playing a flute, the music from which might imitate nature, or represent deeper truths of the cosmos based upon (...) Pythagorean views (which were widespread in Western Greece at the time). The idea that mimesis should be restricted to ideals was made famous by Plato (whose connections to Pythagoreanism and Siracusa are well-known), and famously challenged by his student Aristotle (not to mention by the mimetic character of Plato’s own poetry). This volume gathers essays not only on the philosophical debate about mimesis, but also on its use in architecture, drama, poetry, history, music, ritual, and visual art. The emphasis is on examples from Hellenic cities in Southern Italy and Sicily, but the insights apply far beyond – even to modern times. Contributors include: Thomas Noble Howe, Francisco J. Gonzalez, Gene Fendt, Guilherme Domingues da Motta, Jeremy DeLong, Carolina Araújo, Marie-Élise Zovko, Lidia Palumbo, Sean Driscoll, Konstantinos Gkaleas, Anna Motta, Jure Zovko, Alexander H.

Tomando como referencia la novela periodística Noticia de un secuestro (1996) del Premio Nobel de Literatura de Colombia, Gabriel García Márquez, indago sobre el concepto de víctima, articulado por Olga Islas de González, con la intención de plantear la necesidad que requiere el texto sobre la búsqueda de un Estado nación, justificado en la práctica de la democracia, la libertad de expresión, el cumplimiento de las leyes y la Constitución: en oposición a lo expuesto en el período macrocriminal de los (...) últimos dos decenios del siglo XX en Colombia. Todo ello se muestra con el propósito de identificar el rol de los organismos encargados de contrarrestar las deficiencias de la sociedad colombiana, a través de la Policía (como el hecho de resguardar la seguridad ciudadana, que sería posible con una mayor investigación de su parte y una mejoría en el ámbito de la Criminalística). Asimismo, es de utilidad la extrapolación de las leyes (Decretos 2047/1990, 3030/1990 y 303/1991) que se establecen para aminorar el narcoterrorismo en ese país, sobre todo, para solicitar la extradición de los miembros del Cartel de Medellín a Estados Unidos, donde las sanciones para estos delitos relacionados era la pena de muerte.

Sheep production is the most representative livestock activities in Brazil and in the world. However, the reproductive performance of these animals is determined by factors genetic, physical environment, management and, especially, nutritional. Thirty half-breed lambs from Dorper × Santa Inês were used, with initial weight and age of 31.87 ± 0.5 kg and 157 days, respectively. These animals were prepared on a diet with three food levels (ad libitum, 30% and 70%). Morphometric measurements were measured at intervals of 16 to (...) 20 days in 56 experimental days. The measurements performed were scrotal circumference (CE), chest circumference (CT), body condition score (ECC), withers height (AC) and scrotal bag thickness (EBE), body weight (CP) and semen collection. Interaction occurrence for biometric measurements between food levels and age (p <0.05). The TC and ECC values were higher in animals fed ad libitum (p <0.001). EBE had higher values in animals ad libitum and at 211 days of age (p <0.001). The CP was increasing for the animals ad libitum and (p <0.05) throughout the experiment, while the T30 was only in the initial period. T70 animals did not grow during the whole experiment. CE was influenced by diet (p <0.001) and age (p <0.001) independently. So that animals under food restriction had less development and was higher in older animals. The AC values were influenced only by age (p <0.001), demonstrating the effect of age growth. We conclude that it is not advantageous to submit lambs, it corrects food reproduction. Although it was not possible to assess whether initial malnutrition would bring future problems for the animal's seminal quality, it proved to be immensely negative for the onset of puberty and the development of reproductive structures. -/- REFERÊNCIAS BIBLIOGRÁFICAS AKUMBUGU, F.

RELAÇÃO E EFEITOS BIOQUÍMICO-NUTRICIONAIS SOBRE AS ALTERAÇÕES DO CORPO LÚTEO EM VACAS -/- Emanuel Isaque Cordeiro da Silva Departamento de Agropecuária – IFPE Campus Belo Jardim [email protected] ou [email protected] WhatsApp: (82)98143-8399 -/- •__7. ALTERAÇÕES DO CORPO LÚTEO -/- A estrutura funcional desenvolve-se a partir da cavidade folicular após a ovulação. O corpo lúteo é constituído pelas células da teca interna (pequenas e ativas na primeira fase do seu desenvolvimento) e células da granulosa (grandes e ativas na segunda metade do seu (...) desenvolvimento). As principais características de cada tipo de célula podem resumir-se da seguinte forma: As células pequenas são mais sensíveis à ação da LH porque possui uma quantidade maior de receptores biologicamente ativos para esta hormona e a resposta é mediada pelo sistema AMPc-adelinato ciclase. As grandes células lúteas têm menos receptores para a LH (a maior quantidade são para a PGF2α e a PGE2), e são as responsáveis pela produção da oxitocina luteal (BAH, et al. 2006; CAMPO, 2003). Contrariamente às pequenas células lúteas, a produção de progesterona (P4) é parcialmente controlada pelo sistema Ca+2 - Fosfatil inositol-quinase C (CAMPO, 2003). A regulação da função do corpo lúteo é um mecanismo complexo. Nela intervêm fatores tróficos e líticos que estão presentes em forma simultânea durante todo o ciclo estral, e portanto a estimulação ou inibição da síntese e secreção de P4 depende do balanço entre estes fatores. (CAMPO, 2003). Dentro dos fatores tróficos, os nutrientes desempenham um papel relevante sobre a luteólise e as funções luteotrópicas, entre estas pode-se citar a ação das seguintes: -/- 7.1 Vitaminas Deficiência em betacarotenos. Vitamina A é um termo genérico que designa qualquer composto com atividade de retinol, o trans-retinol, é o composto base, sua forma aldeído e ácido são chamados de retinol e ácido retinóico, respectivamente. Por outro lado, a forma ativa da Vitamina A participa no mecanismo da visão, como 11-cis-retinal. Adicionalmente, o betacaroteno, considerado uma provitamina A é a única forma em que esta encontra nas plantas. Em sentido nutricional, a família da Vitamina A compreende todos os compostos que possuem atividade de retinol, incluindo cerca de cinquenta carotenoides que possuem atividade de provitamina A, aceitando-se que o mais ativo é o trans-betacaroteno (TORRES, et al. 2002). As vitaminas que são necessárias para o crescimento e a produção, também são essenciais para a reprodução. As recomendações atuais de vitamina A são de 75.000 UI/dia durante a lactação e 80.000 UI/dia (nota: 1 mg de Vitamina A = 400 UI) durante o período seco nas vacas leiteiras. A suplementação com vitamina A tem pouco risco de toxicidade, enquanto a sua deficiência pode retardar o aparecimento do primeiro cio/estro, induzir cios/estros silenciosos, aumentar o número de quistos ováricos, reduzir os índices de concepção, causar abortos, mortes embrionárias e ocasionar o nascimento de bezerros debilitados e fracos, uma vez que não irão nascer com os índices e requerimentos ideais de nutrientes passados da mãe para o feto pela placenta, e que, já que a mãe possui deficiência nutricional, o colostro não terá o efeito completo para passar a imunidade essencial ao neonato. Embora os mecanismos de ação não sejam claros, foram notificadas maiores secreções de esteroides ováricos quando as concentrações de β-carotenos no fluido folicular foram elevadas; logo, foram observadas maiores concentrações elevadas de β- estradiol e vitamina A nos folículos que terminaram em ovulação do que naqueles que terminaram em atresia. Para evitar as perdas reprodutivas por deficiência de vitamina A, pode-se optar pela administração oral ou injetável desta ao animal, mediante dois métodos: o primeiro consiste em adicionar 1 a 2,5 kg de premix vitamínico em 1 tonelada de grãos o que supre de 4 a 6.000 UI o que é desejável; o segundo é a administração via injetável em quantidades vide bula do fármaco. 7.2 Minerais O excesso de fósforo é absorvido principalmente no intestino delgado dos mamíferos através de um mecanismo de transporte ativo dependente do sódio, que é estimulado pela pró-hormona 1,25- hidroxivitamina D3. Os ruminantes são capazes de absorver o fósforo dietético em proporção direta às quantidades presentes na ração. Estima-se que aproximadamente 1% do corpo animal é composto de fósforo, do qual 85% está presente nos dentes e no tecido ósseo. Os tecidos moles são capazes de conter entre 0,15-0,20% de fósforo sob a forma de fosfoproteínas, nucleoproteínas, fosfolipídios, fosfato creatinina, adenosintrifosfato, glicose-6-fosfato, etc. Ao nível do plasma sanguíneo, o fósforo apresenta valores de 12,09 mg/dl. Os valores plasmáticos de fósforo são regulados principalmente pelo rim, sendo observado um aumento na excreção urinária do elemento inorgânico quando este excede a capacidade de transporte (REBOLLAR & MATEOS, 1999). O fósforo faz parte dos fosfolipídios, que são importantes no transporte de lipídios e seu metabolismo, como componente das membranas celulares. O fosfato faz parte do RNA e do DNA, componentes celulares vitais, e são essenciais para a síntese proteica. O fosfato faz parte de sistemas enzimáticos como a cocarboxilase e NAD, portanto está envolvido em todos os processos de síntese e regulação energética, dado que o corpo lúteo requer altas quantidades de energia para a síntese celular e hormonal, um excesso de fósforo pode bloquear a capacidade renal da sua regulação gerando um desequilíbrio catiônico que descompensa a relação Na:K, já que deverão ser excretados íons fosfato para regular o equilíbrio ácido-básico, desta forma, os processos celulares em tecidos de alta sensibilidade como o ovário serão afetados em sua função. A situação para prevenção de problemas relacionados ao fósforo (P) já foi tratada em assuntos anteriores, porém, sempre vale frisar para o leitor fiel que me lê que as exigências de P presentes na matéria seca (MS) variam entre 0,17 e 0,59% de P por kg/MS para bovinos de corte e em 0,32 a 0,44% por kg/MS para o gado leiteiro. Dessa forma, dados obtidos por pesquisas, ditam que para a mantença de uma vaca ou quaisquer outra categoria bovina o ideal é o consumo de 1.43 g/100 kg de peso vivo (PV), garantindo assim a prevenção de possíveis afecções reprodutivas como as alterações do corpo lúteo. Gramíneas, forragens, leguminosas e os concentrados fornecem muito bem os requerimentos de fósforo para os animais, todavia deve-se estar atento as relações e dependências do P com outros elementos como o Ca e a relação Na:K (10-15:1 idealmente). 7.3 Compostos estrogênicos Os fitoestrogênios afetam repetidamente a estabilidade do corpo lúteo. Os compostos estrogênicos encontrados principalmente em leguminosas pertencem principalmente a três grupos: isoflavanos, isoflavonas, presentes no gênero Trifolium e praticamente restritos às leguminosas, e cumestanos, que foram estudados na alfafa (Medicago sativa) e na Melilotus alba. Todas as isoflavonas sofrem algum grau de transformação no rúmen, sendo o Isoflavonoide formononetina, na realidade um pró-estrógeno, o único que se ativa no ecossistema ruminal ao ser convertido em equol, enquanto que as demais são degradadas a produtos inativos (RAMOS, et al. 1998). Por fim, a alta concentração no sangue do equol retarda a retroalimentação sobre a hipófise mediante a qual se reduzem os níveis de FSH para dar lugar à onda ovulatória de LH, se esta não ocorrer, o corpo lúteo obviamente não se formará. O conhecimento acerca dos estrogênios na alimentação animal é defasado nos livros sobre o tema, no entanto, o criador pode ficar tranquilo no que tange o tema na prática da sua fazenda e dos seus animais, uma vez que tal elemento é muito bem fornecido naturalmente por meio dos alimentos volumosos presentes no seu pasto. -/- Apoio -/- Realização -/- REFERÊNCIAS BIBLIOGRÁFICAS BAH, Mamadou M. et al.

In Brazil, the social demand for veterinary expertise is growing. However, there is still a shortage of professionals trained in this area to apply specific knowledge to each case. Studies and research into forensic veterinary medicine are necessary for veterinary experts to assist in investigations and legal proceedings. Veterinary medicine has subjects on its curriculum that cover the knowledge needed to apply in the fields of animal health, public health and the environment. The interaction between human and veterinary medicine, as (...) well as other areas of health, is of great importance in the prevention and control of various diseases, both in animals and humans. Some cases of infectious bovine abortion have a major impact not only on cattle farming and animal health, but also on public and environmental health. The concept of "One Health" integrates human medicine and health professionals. In this context, knowledge of infectious abortive diseases that affect animal, human and environmental health is fundamental. Cattle are affected by specific infectious abortive diseases, caused by pathogens with different forms of presentation and transmission mechanisms. These include brucellosis, leptospirosis and listeriosis, which are potentially zoonotic diseases. Controlling these diseases can contribute to effective public health actions and reduce global health risks. In order to establish the diagnosis of these diseases, it is essential to properly collect specimens from live or dead animals under biosafety and biosecurity conditions, following the chain of custody for each case. These procedures allow for greater success in diagnosing the suspected agent and facilitate the investigation of other causes. Animal health standards for the prophylaxis and control of these diseases are established by specific legislation, including those of the Ministry of Agriculture, Livestock and Supply (MALS). This literature review was based on current knowledge on the Pubmed platform, Google Scholar, articles and textbooks. The aim of this article is to identify, understand and discuss the main infectious abortive diseases of cattle in the legal and forensic context, which have an impact on cattle farming, animal health, food safety, public and environmental health. -/- Referências bibliográficas Abdullah, N.

The term ‘coherence’ (and its antonym ‘incoherence’) is used in a bewildering variety of ways in epistemology (and in philosophy more broadly). This entry attempts to bring some discipline to uses of the term by offering a taxonomy of notions of coherence (and incoherence), and then surveying which of the resulting notions is (or should be) at work in the various different contexts in which it is deployed.

Seen from the point of view of evaluation conditions, a usual way to obtain a connexive logic is to take a well-known negation, for example, Boolean negation or de Morgan negation, and then assign special properties to the conditional to validate Aristotle’s and Boethius’ Theses. Nonetheless, another theoretical possibility is to have the extensional or the material conditional and then assign special properties to the negation to validate the theses. In this paper we examine that possibility, not sufficiently explored in (...) the connexive literature yet.We offer a characterization of connexive negation disentangled from the cancellation account of negation, a previous attempt to define connexivity on top of a distinctive negation. We also discuss an ancient view on connexive logics, according to which a valid implication is one where the negation of the consequent is incompatible with the antecedent, and discuss the role of our idea of connexive negation for this kind of view.

Interdisciplinary work on the nature of borders and society has enriched and complicated our understanding of democracy, community, distributive justice, and migration. It reveals the cognitive bias of methodological nationalism, which has distorted normative political thought on these topics, uncritically and often unconsciously adapting and reifying state‐centered conceptions of territory, space, and community. Under methodological nationalism, state territories demarcate the boundaries of the political; society is conceived as composed of immobile, culturally homogenous citizens, each belonging to one and only one (...) state; and the distribution of goods is analyzed according to a stark opposition between the domestic and the international. This article describes how methodological nationalism has shaped central debates in political philosophy and introduces recent work that helps dispel this bias. (shrink)

Higher‐order evidence can make an agent doubt the reliability of her reasoning. When this happens, it seems rational for the agent to adopt a cautious attitude towards her original conclusion, even in cases where the higher‐order evidence is misleading and the agent's original reasons were actually perfectly good. One may think that recoiling to a cautious attitude in the face of misleading self‐doubt involves a failure to properly respond to one's reasons. My aim is to show that this is not (...) so. My proposal is that (misleading) higher‐order evidence can undermine the agent's possession of her first‐order reasons, constituting what I call a dispossessing defeater. After acquiring the higher‐order evidence, the agent is no longer in a position to rely competently on the relevant first‐order considerations as reasons for her original conclusion, so that such reasons stop being available to her (even if they remain as strong as in the absence of the higher‐order evidence). In this way, an agent with misleading higher‐order evidence can adopt a cautious stance towards her original conclusion, while properly responding to the set of reasons that she possesses–a set that is reduced due to the acquisition of higher‐order dispossessing defeaters.

This paper provides new examples of vagueness phenomena with comparatives. I show that comparatives of the form ‘x is ADJ-er than y’ can be vague due to a fuzziness in how much of some property makes for a difference in ADJ-ness. The sorites examples I provide cannot be assimilated to cases of indiscriminability or fuzziness in relevant dimensions, standards, or measurement procedures. A revised degree-based semantics with semiorders, a well studied threshold structure, is developed. The treatment of equatives captures the (...) truth of the claim that adjacent items in the sorites series are not relevantly distinguishable in ADJ-ness; and it avoids validating transitivities that would yield paradoxical conclusions.

Are grounding claims fully general in character? If an object a is F in virtue of being G, does it follow that anything that’s G is F for that reason? According to the thesis of Weak Formality, the answer here is ‘yes’. In this paper, however, I argue that there is philosophical utility in rejecting this thesis. More exactly, I argue that two currently unresolved problems in contemporary metaphysics can be dealt with if we hold that there can be cases (...) of ‘kind-dependent grounding’, the key thought being that once we allow for such cases, we must also accept that Weak Formality is false.

Social psychologists often describe “implicit” racial biases as entirely unconscious, and as mere associations between groups and traits, which lack intentional content, e.g., we associate “black” and “athletic” in much the same way we associate “salt” and “pepper.” However, recent empirical evidence consistently suggests that individuals are aware of their implicit biases, albeit in partial, inarticulate, or even distorted ways. Moreover, evidence suggests that implicit biases are not “dumb” semantic associations, but instead reflect our skillful, norm-sensitive, and embodied engagement with (...) social reality. This essay draws on phenomenological and hermeneutic methods and concepts to better understand what social-psychological research has begun to reveal about the conscious access individuals have to their own racial attitudes, as well as the intentional contents of the attitudes themselves. -/- First, I argue that implicit racial biases form part of the “background” of social experience. That is, while they exert a pervasive influence on our perceptions, judgments, and actions, they are frequently felt but not noticed, or noticed but misinterpreted. Second, I argue that our unreflective racial attitudes are neither mere associations nor fully articulated, propositionally structured beliefs or emotions. Their intentional contents are fundamentally indeterminate. For example, when a white person experiences a “gut feeling” of discomfort during an interaction with a black person, there is a question about the meaning or nature of that discomfort. Is it a fear of black people? Is it anxiety about appearing racist? There is, I argue, no general, determinate answer to such questions. The contents of our unreflective racial attitudes are fundamentally vague and open-ended, although I explain how they nevertheless take on particular shapes and implications—that is, their content can become determinate—depending on context, social meaning, and structural power relations. (If, for example, a perceived authority figure, such as a politician, parent, or scientist, encourages you to believe that your uncomfortable gut feeling is a justified fear of other social groups, then that is what your gut feeling is likely to become.).

In this paper, I defend the view that it is wrong for us to consume only, or overwhelmingly, media that broadly aligns with our own political viewpoints: that is, it is wrong to be politically “partisan” in our decisions about what media to consume. We are obligated to consume media that aligns with political viewpoints other than our own – to “diversify our sources”. This is so even if our own views are, as a matter of fact, substantively correct.

The republican case for workplace democracy is presented and defended from two alternative means of ensuring freedom from arbitrary interference in the firm—namely, the right to freely exit the firm and workplace regulation. This paper shows, respectively, that costless exit is neither possible nor desirable in either perfect or imperfect labor markets, and that managerial discretion is both desirable and inevitable due to the incompleteness of employment contracts and labor legislation. The paper then shows that WD is necessary, from a (...) republican standpoint, if workers’ interests are to be adequately tracked in the exercise of managerial authority. Three important objections are finally addressed— that WD is redundant, that it is unnecessary provided that litigation and unionism can produce similar outcomes, and that it falls short of ensuring republican freedom compared to self-employment.

In a companion paper (Byrne and Green 2023) we disentangled the main characterizations of naïve realism and argued that illusions provide the best proving ground for naïve realism and its main rival, representationalism. According to naïve realism, illusions never involve perceptual error. We assessed two leading attempts to explain apparent perceptual error away, from William Fish and Bill Brewer, and concluded that they fail. This paper considers another prominent attempt, from Craig French and Ian Phillips, and also sketches the case (...) for representationalism. (shrink)

According to orthodoxy, perceptual beliefs are caused by perceptual experiences. The paper argues that this view makes it impossible to explain how experiences can be epistemically significant. A rival account, on which experiences in the “good case” are ways of knowing, is set out and defended.

To understand what non-propositional content is and whether there are any such contents, we first need to know what propositional content is. That issue will be the focus of the first section of this essay. In the second section, with an understanding of propositional content in hand, we will consider representations that fail to have propositional content. In contrast to recent literature, it will be argued that metaphysical considerations concerning what's represented, rather than linguistic considerations, are a more promising way (...) of establishing non-propositional contents. To keep the discussion containable, focus will be on representational mental states, though many of the considerations can be extended to other forms of representation. (shrink)

El Realismo Especulativo, Nuevo Realismo o Realismo Postcontinental es una corriente ecléctica que viene a superar las aporías e insuficiencias de la filosofía continental desde una perspectiva a la que se le podrían achacar los mismos problemas que la perspectiva idealista y constructivista de los filósofos continentales. Para el desarrollo de la filosofía es importante entablar conversación los autores de este movimiento. En el presente artículo se presenta una aproximación a los aciertos e insuficiencias de las ontologías de dos autores (...) de la corriente como son Markus Gabriel y Graham Harman. Se presentan los aciertos e insuficiencias del realismo neutro de Markus Gabriel y de la Ontología Orientada a los Objetos, en este orden. En el último epígrafe, a modo de conclusiones, se señalan los puntos en común de las ontologías y se aporta la idea de acontecimiento como línea de investigación que supere las aporías que emergen de la contraposición entre el idealismo y realismo.

Semanticists face substitution challenges even outside of contexts commonly recognized as opaque. Jennifer M. Saul has drawn attention to pairs of simple sentences - her term for sentences lacking a that-clause operator - of which the following are typical: -/- (1) Clark Kent went into the phone booth, and Superman came out. (1*) Clark Kent went into the phone booth, and Clark Kent came out. -/- (2) Superman is more successful with women than Clark Kent. (2*) Superman is more successful (...) with women than Superman. -/- She challenges us to explain why the upper and lower sentences in each pair differ, or at least appear to differ, in their truth-values and hence truth-conditions. This appearance of substitution failure is inherently puzzling. Moreover, it is taken by Saul to generate a dilemma for anyone hostile to direct reference accounts of that-clause constructions. Direct reference theorists regard the appearance of substitution failure in that-clause contexts as mere appearance, to be dealt with pragmatically rather than semantically. -/- Critics of such accounts need to say something about simple-sentence cases. If they choose to allow that intuitions of substitution failure can be over-ridden and explained away pragmatically in simple-sentence cases but not in that-clause cases, they lay themselves open to the charge of operating a double standard. But if they do not choose this option, they must offer a semantic explanation of apparent substitution failure in simple-sentence cases - no easy task, it turns out. Other respondents to Saul's challenge have sought to provide elaborate semantic treatments. In contrast, this paper proposes a far simpler pragmatic explanation of intuitions of substitution failure in simple sentences, an explanation that deploys no more resources than are to be found in Grice's 'Logic and Conversation'. Ironically, this proposal turns out to be incompatible with a direct reference perspective. So if it is, as I maintain, the most plausible treatment of simple-sentence cases available, Saul's initial thought gets turned around 180 degrees: the phenomenon she has drawn attention to ends up representing a challenge to supporters of direct reference theories.

In discussions of the emotions, it is commonplace to wheel out examples of people who know that rollercoasters aren’t dangerous but who fear them anyway. Such cases are well known to have been troubling for cognitivists who hold the emotions are judgments or beliefs. But more recently, it has been argued that the very theories that emerged from the failure of cognitivism face trouble as well. One gets the sense that the theory that can accomplish this will win a crucial (...) point over its competitors. In the present paper I offer a new approach to making sense of the normative tension to which recalcitrant emotions give rise. Interestingly, the approach is one that can be adopted by anyone willing to grant that emotions are themselves governed by norms. (shrink)

I argue, contrary to the consensus of most contemporary work in ethics, that there are no (fundamentally, distinctively) prudential reasons for action. That is to say: there is no class of reasons for action that is distinctively and fundamentally about the promotion of the agent’s own well-being. Considerations to do with the agent’s well-being can supply the agent with reasons only in virtue of her well-being mattering morally or in virtue of her caring about her own well-being. In both of (...) these cases, the way that such prudential considerations supply reasons for action is a way that the well-being of others can supply reasons for action too. (shrink)

I want to make sense of the view that singular causation involves a metaphysical necessary connection. By this I understand, where A and B are particulars, that ifA causes B then in every possible world in which A (or an A-indiscernible) or B (or a B-indiscernible) occurs, A (or an Aindiscernible) and B (or a B-indiscernible) occur. In the singularist approach that I will favour causal facts do not supervene on laws, causal relata are best understood as tropes, causation is (...) founded on the nature of its terms, and the necessity thus involved does not entail essentialism, determinism, and other usual problems.

This paper demarcates a theoretically interesting class of "evaluational adjectives." This class includes predicates expressing various kinds of normative and epistemic evaluation, such as predicates of personal taste, aesthetic adjectives, moral adjectives, and epistemic adjectives, among others. Evaluational adjectives are distinguished, empirically, in exhibiting phenomena such as discourse-oriented use, felicitous embedding under the attitude verb `find', and sorites-susceptibility in the comparative form. A unified degree-based semantics is developed: What distinguishes evaluational adjectives, semantically, is that they denote context-dependent measure functions ("evaluational (...) perspectives")—context-dependent mappings to degrees of taste, beauty, probability, etc., depending on the adjective. This perspective-sensitivity characterizing the class of evaluational adjectives cannot be assimilated to vagueness, sensitivity to an experiencer argument, or multidimensionality; and it cannot be demarcated in terms of pretheoretic notions of subjectivity, common in the literature. I propose that certain diagnostics for "subjective" expressions be analyzed instead in terms of a precisely specified kind of discourse-oriented use of context-sensitive language. I close by applying the account to `find x PRED' ascriptions. (shrink)

Relationalists about episodic memory must endorse a disjunctivist theory of memory-experience according to which cases of genuine memory and cases of total confabulation involve distinct kinds of mental event with different natures. This paper is concerned with a pair of arguments against this view, which are analogues of the ‘causal argument’ and the ‘screening off argument’ that have been pressed in recent literature against relationalist (and hence disjunctivist) theories of perception. The central claim to be advanced is that to deal (...) with these two arguments, memory disjunctivists both can and should draw on resources that are standardly appealed to by rival common factor theories of episodic memory, and, in particular, to the idea that genuine memories and merely apparent ones are to be distinguished, at least in part, in terms of the distinctive ways in which they are caused. On the proposed view, there are substantive causal constraints associated both with cases of genuine memory and with cases of mere confabulation. The resulting theory thus tells us something important about the nature both of genuine memories and of mere confabulations, namely, that such experiences must be caused in certain distinctive ways and cannot occur except as the result of a distinctive sort of causal process. In addition, the theory enables the disjunctivist to offer a unified response to an important pair of arguments against her view. (shrink)

I present a novel position vis-à-vis the views in the Latin American philosophy literature regarding whether subjects more aptly use "Hispanic" or "Latinx" to refer to Hispanic- or-Latinx people. To this end, I will argue (C) the term "Afro-Latinx" is more apt than "Hispanic" or "Latinx" in a significant number of cases. This conclusion is based on three premises. The first premise (P1) is that use of "Afro-Latinx" provides subjects with understanding of how certain events depend on anti-Black racism, US (...) society's racially unjust structure and US colonial policy. The second premise (P2) is that that neither the term "Hispanic" nor the term "Latinx" provide subjects with this understanding of how certain events depend on anti-Black racism, US society's racially unjust structure and US colonial policy. The third premise (P3) is that the term "Afro-Latinx" provides subjects with more understanding of these events than the terms, "Hispanic" and "Latinx.” I present three cases which feature the experiences of Afro-Dominican people. The 1992 murder of Dominican man Kiko García by New York Police officer O’Keefe is first case. The second case is the Washington Heights Uprising that ensued Kiko García’ murder. An instance where a nightclub bouncer in the Dominican Republic denies a Dominican women entry because of her hair texture composes the third case. (shrink)

This paper presents a novel challenge for the panpsychist solution to the problem of consciousness. It advances three main claims. First, that the problem of consciousness is really an instance of a more general problem: that of grounding the qualitative. Second, that we should want a general solution to this problem. Third, that panpsychism cannot provide it. I also suggest two further things: (1) that alternative kinds of Russellian monism may avoid the problem in ways panpsychists cannot, and (2) that (...) a kind of neo-Aristotelian or ground-theoretical physicalism fares just as well here if not better.

According to the classical account, propositions are sui generis, abstract, intrinsically-representational entities and our cognitive attitudes, and the token states within us that realize those attitudes, represent as they do in virtue of their propositional objects. In light of a desire to explain how it could be that propositions represent, much of the recent literature on propositions has pressured various aspects of this account. In place of the classical account, revisionists have aimed to understand propositions in terms of more familiar (...) entities such as facts, types of mental or linguistic acts, and even properties. But we think that the metaphysical story about propositions is much simpler than either the classical theorist or the revisionist would have you believe. In what follows, we argue that a proper understanding of the nature of our cognitive relations to propositions shows that the question of whether propositions themselves represent is, at best, a distraction. We will argue that once this distraction is removed, the possibility of a very pleasing, minimalist story of propositions emerges; a story that appeals only to assumptions that are shared by all theorists in the relevant debate.

This paper offers a positive account of an important but under-explored class of mental states, non-propositional attitudes such as loving one’s department, liking lattice structures, fearing Freddy Krueger, and hating Sherlock Holmes. In broadest terms, the view reached is a representationalist account guided by two puzzles. The proposal allows one to say in an elegant way what differentiates a propositional attitude from an attitude merely about a proposition. The proposal also allows one to offer a unified account of the non-propositional (...) attitudes that captures both empty and non-empty cases by properly locating the posited representations in the metaphysical structure of the attitudes.

Political theorists have recently sought to replace the liberal, contractual theory of the firm with a political view that models the authority relation of employee to firm, and its appropriate regulation, on that of subject to state. This view is liable to serious difficulties, however, given existing discontinuities between corporate and civil authority as to their coerciveness, entry and exit conditions, scope, legal standing, and efficiency constraints. I here inspect these, and argue that, albeit in some cases significant, such discontinuities (...) fail to undermine the firm/state analogy, either because they are not significant enough to do so or because the particular trait on which they hinge is not decisive for how authority, in the state and in the firm, should be regulated to be legitimate. A pro tanto requirement exists, I thus argue, that corporate authority be held to regulatory norms comparable to those legitimate states abide by, including civil liberties, rule-of-law constraints, and accountability to subjects.

Should we understand implicit attitudes on the model of belief? I argue that implicit attitudes are (probably) members of a different psychological kind altogether, because they seem to be insensitive to the logical form of an agent’s thoughts and perceptions. A state is sensitive to logical form only if it is sensitive to the logical constituents of the content of other states (e.g., operators like negation and conditional). I explain sensitivity to logical form and argue that it is a necessary (...) condition for belief. I appeal to two areas of research that seem to show that implicit attitudes fail spectacularly to satisfy this condition—although persistent gaps in the empirical literature leave matters inconclusive. I sketch an alternative account, according to which implicit attitudes are sensitive merely to spatiotemporal relations in thought and perception, i.e., the spatial and temporal orders in which people think, see, or hear things.

Kant’s metaphilosophy has three main parts: (1) an essentialist project (“What is philosophy?”); (2) a methodological project (“How do we do philosophy?”); and (3) a taxonomic project (“What are the different parts of philosophy, and how are they related?”). This paper focuses on the third project. In particular, it explores one of the most intriguing yet puzzling aspects of Kant’s philosophy, viz. the relationship between what Kant calls ‘pure’ philosophy vs. ‘applied’, ‘empirical’ or what we can broadly refer to as (...) ‘impure’ philosophy. (As we shall see, in order to be able to address this third project, we shall also need to examine the other two projects in detail.) My plan is as follows. First, I discuss four main areas of pure vs. impure philosophy: (i) ‘pure logic’ vs. ‘applied logic’; (ii) ‘rational psychology’ vs. ‘empirical psychology’; (iii) ‘pure metaphysics of nature’ vs. ‘physics’ and (iv) ‘pure morality’ or a ‘metaphysics of morals’ vs. ‘moral anthropology’, ‘practical anthropology’ or ‘applied moral philosophy’. Based on this, I identify four key differences between pure and impure philosophy. Second, I critically examine four different readings of Kant’s views about the status of ‘impure’ philosophy: (a) that it is not genuine philosophy; (b) that it is bad or inferior philosophy; (c) that it is instrumentally valuable; and (d) that it constitutes an indispensable part of Kant’s philosophy, both in a theoretical and practical sense. I argue that Kant is best interpreted as endorsing readings (c) and (d). Third, I offer some concluding remarks. (shrink)

At the heart of John Broome’s research program in the philosophy of normativity is a distinction between reasons, on one hand, and requirements of rationality, on the other. I am a friend of Broome’s view that this distinction is deep and important, and that neither notion can be analyzed in terms of the other. However, I also think there are major challenges that this view is yet to meet. In the first part of the paper, I’ll raise four such challenges, (...) and programmatically indicate how I think such challenges might be headed off. In the second part of the paper, I’ll discuss a third normative notion that Broome is interested in: that of (rules of) correct reasoning. On Broome’s view, correct reasoning is closely tied to requirements of rationality. More particularly, every rule of correct reasoning corresponds to a “basing permission”, which states that it’s rationally permissible to base one attitude on one or more other attitudes. I’ll argue that this proposal can’t be made to work. If I’m right, this suggests that the same kind of pulling-apart that Broome has effected so persuasively with respect to reasons and requirements of rationality needs to be effected again to separate rules of correct reasoning from both of those other categories.

In times of climate change and public debt, a concern for intergenerational justice should lead us to have a closer look at theories of intergenerational justice. It should also press us to provide institutional design proposals to change the decision-making world that surrounds us. This book provides an exhaustive overview of the most important institutional proposals as well as a systematic and theoretical discussion of their respective features and advantages. It focuses on institutional proposals aimed at taking the interests of (...) future generations more seriously, and does so from the perspective of applied political philosophy, being explicit about the underlying normative choices and the latest developments in the social sciences. It provides citizens, activists, firms, charities, public authorities, policy-analysts, students, and academics with the body of knowledge necessary to understand what our institutional options are and what they entail if we are concerned about today's excessive short-termism.

Many believe that we ought to save a large number from being permanently bedridden rather than save one from death. Many also believe that we ought to save one from death rather than a multitude from a very minor harm, no matter how large this multitude. I argue that a principle I call “Aggregate Relevant Claims” satisfactorily explains these judgments. I offer a rationale for this principle and defend it against objections.

Singular terms used in fictions for fictional characters raise well-known philosophical issues, explored in depth in the literature. But philosophers typically assume that names already in use to refer to “moderatesized specimens of dry goods” cause no special problem when occurring in fictions, behaving there as they ordinarily do in straightforward assertions. In this paper I continue a debate with Stacie Friend, arguing against this for the exceptionalist view that names of real entities in fictional discourse don’t work there as (...) they do in simple-sentence assertions, but rather as fictional names do.

This paper tries to do three things. First, it tries to make it plausible that correct rules of reasoning do not always preserve justification: in other words, if you begin with a justified attitude, and reason correctly from that premise, it can nevertheless happen that you’ll nevertheless arrive at an unjustified attitude. Attempts to show that such cases in fact involve following an incorrect rule of reasoning cannot be vindicated. Second, it also argues that correct rules of reasoning do not (...) even correspond to permissions of “structural rationality”: it is not always structurally permissible to base an attitude on other attitudes from which it follows by correct reasoning. Third, from these observations it tries to build a somewhat positive account of the correctness of rules of reasoning as a more sui generis notion irreducible to either justification or structural rationality. This account vindicates an important unity of theoretical and practical reasoning as well as a qualified version of the thesis that deductive logic supplies correct rules of reasoning. (shrink)

In the present essay, I trace the way in which Derrida engages the theme of the destruction of philosophy in his reading of Heidegger’s work in the 1964-65 seminar, Heidegger: The Question of Being and History. Specifically, I focus on a close reading of the first three sessions in order to show the way in which the theme of the destruction of philosophy appears in relation to the posing of three questions, namely, the questions of being, history, and metaphor. In (...) all three sessions, I will show that the questions of being, history, and metaphor allow Heidegger, according to Derrida, to brush against the very limits of philosophy. However, Derrida’s own interpretation reveals an interesting emphasis on the destruction of philosophy that, while definitely inspired by Heidegger, slightly begins to go beyond him. For this reason, I will turn to his more critical appraisal of Heidegger’s trajectory in the final two sessions. In so doing, I claim that Derrida’s positions in these final sessions will show a critical distance vis-à-vis Heidegger that will foreshadow the very question that will remain decisive throughout his nearly 40 year engagement with Heidegger’s work, namely, the question of difference.

Recent work on rationality has been increasingly attentive to “coherence requirements”, with heated debates about both the content of such requirements and their normative status (e.g., whether there is necessarily reason to comply with them). Yet there is little to no work on the metanormative status of coherence requirements. Metaphysically: what is it for two or more mental states to be jointly incoherent, such that they are banned by a coherence requirement? In virtue of what are some putative requirements genuine (...) and others not? Epistemologically: how are we to know which of the requirements are genuine and which aren’t? This paper tries to offer an account that answers these questions. On my account, the incoherence of a set of attitudinal mental states is a matter of its being (partially) constitutive of the mental states in question that, for any agent that holds these attitudes jointly, the agent is disposed, when conditions of full transparency are met, to give up at least one of the attitudes.

Our goal in this paper is to articulate a precise concept of at least a certain kind of disease-mongering, showing how pharmaceutical marketing can commercially exploit certain diseases when their best definition is given through the success of a treatment in a clinical trial. We distinguish two types of disease-mongering according to the way they exploit the definition of the trial population for marketing purposes. We argue that behind these two forms of disease-mongering there are two well-known problems in the (...) statistical methodology of clinical trials (the reference class problem and the distinction between statistical and clinical significance). Overcoming them is far from simple. (shrink)

This paper delves into the character concept as applied to reproduction. Our argument is that the prevailing functional-adaptationist perspective falls short in explaining the evolution of reproductive traits, and we propose an alternative organismal-relational approach that incorporates the developmental and interactive aspects of reproduction. To begin, we define the functional individuation of reproductive traits as evolutionary strategies aimed at enhancing fitness, and we demonstrate how this perspective influences the classification of reproductive characters and modes, the comprehension of shared traits as (...) resulting from conflicts of evolutionary interest between individuals, and the explanation of reproductive diversity. After outlining the shortcomings of this framework, we introduce an organismal-relational approach grounded in evolutionary developmental studies of reproduction. This view provides a revised classification for reproductive characters and modes and offers a new understanding of interorganismal traits that takes into account their inherently relational nature. Lastly, we present the research agenda that emerges from this approach, which addresses the core explanatory gaps left by the adaptationist perspective, including the explanation of reproductive homologies and homoplasies, the developmental constraints associated with the evolution of reproductive modes, and the evolvability of reproductive characters.

Are women (simply) adult human females? Dictionaries suggest that they are. However, philosophers who have explicitly considered the question invariably answer no. This paper argues that they are wrong. The orthodox view is that the category *woman* is a social category, like the categories *widow* and *police officer*, although exactly what this social category consists in is a matter of considerable disagreement. In any event, orthodoxy has it that *woman* is definitely not a biological category, like the categories *amphibian* or (...) *adult human female*. -/- In the first part, a number of arguments are given for the view that women are adult human females; the second part turns to rebutting the main objections. Finally, a couple of morals are briefly noted: one for activist sloganeering, and one for ameliorative projects that seek to change the meaning of ‘woman’. (shrink)

In this paper, I defend a new theory of normative reasons called reasons as good bases, according to which a normative reason to φ is something that is a good basis for φing. The idea is that the grounds on which we do things—bases—can be better or worse as things of their kind, and a normative reason—a good reason—is something that is just a good instance of such a ground. After introducing RGB, I clarify what it is to be a (...) good basis, and argue that RGB has various attractive features: it has intuitive implications, makes good sense of the weights of reasons, and attractively explains the relationship between normative reasons and motivating reasons. I then briefly defend the view from objections and compare it to rivals. Finally, I sketch two possible implications of RGB: some kind of constitutivism, according to which the norms that govern us are explained by the nature of agency, and second, the claim that agents who do things for reasons generally do them for good reasons.
