The present article is devoted to two issues. The first is the identification of lead and tin in medieval Arabic alchemy. The second is the investigation of whether Arabic alchemists differentiate between these problematic substances or not. These two issues are investigated in the light of a comparison which is made between the facts that are stated about the two problematic substances in the original Arabic alchemical works and those stated in modern chemical literature. It is proved that Arabic alchemists (...) made a sharp distinction between lead and tin. Also, it becomes clear that these two metals were used in a satisfactory purity in the era of medieval Arabic alchemy. As a consequence of the present study, some conclusions are drawn about the existence of some categories of ‘derivatives’ of fusible bodies in Arabic alchemy which are degenerate to modern categories of oxides, carbonates, etc. (shrink)

Resumen: Esta nota crítica analiza la perspectiva que Martha Nussbaum presenta sobre la emoción de la ira en su último libro Anger and Forgiveness. Resentment, Generosity, Justice. Para ello sitúo esta obra en el contexto del proyecto filosófico de la autora y señalo algunos cambios y continuidades en su análisis de la ira; después reviso a la luz de este nuevo libro algunas de las críticas que, centradas en la reivindicación de la ira, ha recibido su propuesta de una cultura (...) política centrada en las emociones “humanizadoras”.: This critical note examines Martha Nussbaum’s perspective on anger presented in her last book Anger and Forgiveness. Resentment, Generosity, Justice. I place this book in the context of Nussbaum’s philosophical project in order to trace changes and continuities in her views on anger, and then I examine some criticisms that have been held against her proposal of a political culture based on humanizing emotions based on the vindication of anger.

Science has always been tightly associated with environmental ethics in a way traditional ethics has not. However, despite this proximity, science has had a merely informational role, where it must inform ethics but not intervene in ethical judgment. Science is seen as an amoral enterprise, requiring an ethics rather than recommending one. In this paper I try to go against this common view. First, I give a critique of the naturalistic fallacy following the lines of Frankena. Then I go on (...) to describe the two possible roles science can have in ethical though, and in environmental ethics in particular. As it turns out, science does not only inform ethics, but can actually have moral import and intervene in moral judgment. Finally, from an ecocentric point of view, I try to illustrate this last point by construing the ecological notion of resilience as a moral boundary—a scientifically determined boundary between right and wrong.

Resumen: En su libro Mujeres y discursos gerenciales. Hacia la autogestión feminista, María Medina-Vicent aborda desde una perspectiva crítica feminista los discursos gerenciales dirigidos a las mujeres, desvelando el androcentrismo y la presencia —y perpetuación— de tradicionales roles y estereotipos de género en los modelos de gestión. Mi propuesta pretende incidir en dos aspectos del análisis realizado por Medina-Vicent, por un lado, remarcar los peligros de la despolitización de los discursos gerenciales dirigidos a mujeres —sobre todo en tanto que la (...) literatura gerencial acaba por informarnos a todas—. Por otro, profundizar en la crítica que la autora realiza de la cooptación del feminismo por parte de estos discursos.: In her book Mujeres y discursos gerenciales. Hacia la autogestión feminista, Medina-Vicent approaches management discourses aimed at women from a critical feminist perspective, revealing the androcentrism and the presence and perpetuation of traditional gender roles and stereotypes in management models. My proposal aims to highlight two aspects of Medina-Vicent’s analysis: on the one hand, to highlight the dangers of depoliticizing management discourses aimed at women - especially insofar as management literature ends up informing us all. On the other hand, the author’s critique of the co-optation of feminism by these discourses will be explored in greater depth. Palabras clave: discursos gerenciales, teoría feminista, antifeminismo, despolitización. Keywords: managerial discourses, feminist theory, antifeminism, depoliticization. (shrink)

This chapter discusses the nature and value of political disagreement, with reference to contemporary work in political philosophy. I will attempt to answer the following questions: Why do we disagree? Is political disagreement a good thing? Do we have a duty to disagree? Should we expect consensus or mere compromise in politics? When is civil disobedience a justified way to express disagreement with the law? Is consensus a threat to democracy?

Una profesora de secundaria narra en tres momentos distintos los sucesos que han marcado su devenir como mujer, madre y enseñante durante la pandemia por COVID-19. En un recorrido que transcurre entre la sorpresa, la incertidumbre y el desencanto, emerge la reflexión de que la escuela ya no es ni será la misma, no solo por la diferencia entre la educación presencial y a distancia, sino porque las vidas de todos y todas se han transformado, porque muchos escolares han dejado (...) la escuela, más de cinco millones de niños, niñas y jóvenes. Afirma con contundencia ¡Este bicho tiene aporofobia! en alusión a la desigualdad social y la afectación a las personas en situación de pobreza. Reflexiona en torno a las distintas respuestas del profesorado y del sistema educativo, haciendo una fuerte crítica a la viabilidad y resultados del modelo “aprende en casa”. De ninguna manera es ajena a los efectos de la pandemia en los planos económico, laboral y educativo, pero se muestra renuente a dar credibilidad y adoptar soluciones que ubican la problemática solo en el plano de la voluntad y esfuerzo personal, sin reconocer que se trata de una crisis sistémica, que abarca a las instituciones sociales en conjunto. La expresión de emociones, vivencias y aprendizajes no esperados ante la ruptura de lo cotidiano, así como la experiencia del confinamiento por más de año y medio, permiten avizorar una nueva subjetividad en los actores de la educación, que deberá ser tomada en cuenta en el eventual regreso a los planteles escolares.

En el último tercio del siglo XIX y comienzos del XX, la prensa se constituyó en el medio más eficaz de difusión y conocimiento de la moda. Las revistas dirigidas a la mujer se encargaron de divulgar la moda con el fin de orientar su participación en el consumo de la misma. Un buen ejemplo de ello nos lo ofrece la revista La mujer donde coexisten discursos paralelos y contradictorios sobre los efectos que la moda ocasiona en la mujer y (...) en la sociedad. La prensa destacó la importancia que la moda ejercía en la belleza de la mujer y al mismo tiempo se encargó de tranquilizar al patriarcado justificando que la belleza de la mujer debía ser exclusivamente para agradar al marido. Los recursos publicitarios; grabados, anuncios, figurines, láminas, etc., que utiliza la prensa de esta época, sirven para la construcción de un nuevo modelo de feminidad más acorde con determinados aspectos de la modernización. La publicidad sirve como aliciente para que la mujer burguesa adquiera mayor protagonismo en la concepción de lo moderno y dentro del contexto urbano que es donde se desarrolla el consumo de la moda.

Abstract:Representations of the space of the village, the wilderness, and the overlapping edge of the forest between them often play a critical role in intercultural collisions between the “developing” world's spaces and pressures from the ‘developed’ world's activities within them. These collisions include land grabs and resource extraction, conversion of forest or wilderness to mechanized agriculture, uneven legal disputes over what constitutes ownership and use, and conservation efforts to reduce climate change or restore genetic biodiversity in forests. This study illuminates (...) how the physical and perceptual spaces of village, wilderness, and forest change, resist change, and are forced to change in three key domains: health (traditional medicine), food security (hunting, farming, and resource extraction in general), and use-ownership (as indigenous knowledge, occupancy, and access to land-use generally). Findings from the study disclose a need to include time (as the pace of change) whenever changed perceptions of space are proposed or occur. Recommendations include applying the criterion to strive always for the least disruptive (short-term) procedures for addressing a problem such that those outcomes achieve the most sustainable impacts over the long-term.

Objective: To assess the knowledge of four groups of individuals regarding who is legally authorised to consent to health care or research involving older patients.Design: A provincewide postal survey.Setting: Province of Quebec, Canada.Participants: Three hundred older adults, 434 informal caregivers of cognitively impaired individuals, 98 researchers in aging and 136 members of research ethics boards .Measurements: Knowledge was assessed through a pretested postal questionnaire comprising five vignettes that describe hypothetical situations involving an older adult who requires medical care or is (...) solicited for research. The respondent had to identify the person who is legally authorised to provide consent.Results: Nearly 80% of all respondents provided the correct answer when the hypothetical scenario depicted a person who was competent to consent or incompetent but legally represented. Knowledge was worse for the scenario describing a research situation that involved an incompetent adult without a legal guardian.Conclusion: The observed lack of knowledge raises doubts about the ability of current legislation to truly protect the rights of older adults with diminished decision making capacity. It points to the need for educational programmes aimed at increasing public awareness of the legislation put in place for those requiring special protection. (shrink)

This paper aims to map the different theoretical options related to the Precautionary Principle (PP). Great part of the literature on it can be systematized by answering to three different questions: is there a basic structure in the PP? If so, in which interpretation of the PP does this structure express itself? Finally, are its damage or knowledge conditions fixed or adjustable? The first question separates realist from non-realist approaches. The second question allows us to discriminate monist, dualist, or pluralist (...) positions in relation to the three interpretations of the PP: decision rule, procedural requirement, or epistemic rule. Finally, the third question distinguishes rigid from non-rigid formulations of the principle. Based on this mapping, one can not only navigate through the different formulations of the PP present both in official documents and in specialized literature, but also deflect some of its common objections, and understand Hans Jonas’ eventual connection with PP. Notwithstanding, this mapping does not capture other important themes attached to PP, which motivates a final distinction between narrow and broader forms of PP. (shrink)

O objetivo deste artigo é analisar as relações entre agnotologia (construção social da ignorância) e o princípio da precaução (PP) sob dois aspectos. O primeiro diz respeito à crítica de que parcela dos defensores do PP teria utilizado estratégias de construção de ignorância. A partir do trabalho do filósofo Daniel Steel, mostro como elas enfraquecem um critério interno ao próprio princípio: a proporcionalidade. Sob o segundo aspecto, comento documentos tornados públicos que evidenciam estratégias de agnotologia por setores da indústria tanto (...) sobre o PP como sobre resultados científicos para que ele não fosse aplicado. Semelhante exposição ainda não foi realizada na literatura especializada no PP. A partir dessa análise, busco contribuir para identificar estratégias de agnotologia em debates sobre o PP. (shrink)

Primeiramente, oferecemos uma apresentação teórica da representação do pensamento prático, começando pela distinção entre silogismo dialético e silogismo demonstrativo. Fazemos referência à crítica de Toulmin contra o dedutivismo dominante de seu tempo. Em seguida, fornecemos argumentos para apoiar a relevância heurística do modelo de Toulmin para entender a discussão sobre a inclusão da lógica padrão na representação do pensamento comum. Afirmamos que o projeto analítico toulmaniano permite entender, com clareza metódica, a derrotabilidade dos argumentos do senso comum por meio da (...) investigação da noção modal de probabilidade na linguagem comum. First, we offer theoretical resemblance of the representation of practical reasoning, beginning with the distinction between demonstrative and dialectical syllogism. We make reference to the Toulmin’s critique against to the dominant deductivism in his time. Then we give arguments to sustain the heuristic relevance of Toulmin’s model to understand the discussion about the inclusion of default logics in the representation of ordinary reasoning. We assert that the Toulminian analytic design allows to understand, with methodical clarity, the defeasibility of common sense arguments by means of the investigation of the modal notion of probability in ordinary language.

Taking a Blue Marble evaluation perspective means viewing the world holistically. It begins with watching for, making sense of, and interpreting the implications of things that are interconnected in the global system. Blue Marble thinkers see the interconnections between the global and local, the macro and the micro, and the relationships between worldwide patterns and area-specific challenges. Part 1 of this book presents and explains four overarching Blue Marble principles. Part 2 examines and elaborates the implications of the overarching principles (...) with 12 operating principles. The Blue Marble perspective is both an approach to evaluation and a way of thinking about all aspects of systems change initiatives and interventions, at all levels at which they occur from local to global.

RESUMEN La poesía de William Wordsworth pasaba por ser, entre muchos de sus comentaristas contemporáneos, una poesía pensante. Ya sea que se hablase de un sentido edificante de su poesía, de una perspectiva refrescante acerca de las cosas cotidianas o bien de un pensamiento filosófico, la poesía de Wordsworth siempre fue considerada como un notable esfuerzo por elevar el poema a una categoría ontológica. Dentro de este contexto, la imaginación cobra una gran importancia. Se analiza en qué sentido la imaginación (...) es el centro ontológico de la poesía de Wordsworth. ABSTRACT William Wordsworth's poetry was a thinking poetry, according to many of his contemporaries. Whether it was due to the edifying nature of his poetry, his refreshing approach to everyday things, or his philosophical thought, Wordsworth's poetry was always considered as a notable effort to elevate the poem to ontological category. In this context, imagination acquires great importance. The article analyzes the sense in which imagination is the ontological center of Wordsworth's poetry. RESUMO A poesia de William Wordsworth passava por ser, entre muitos de seus comentaristas contemporâneos, uma poesia pensante.

Background: Family members are often required to act as substitute decision-makers when health care or research participation decisions must be made for an incapacitated relative. Yet most families are unable to accurately predict older adult preferences regarding future health care and willingness to engage in research studies. Discussion and documentation of preferences could improve proxies' abilities to decide for their loved ones. This trial assesses the efficacy of an advance planning intervention in improving the accuracy of substitute decision-making and increasing (...) the frequency of documented preferences for health care and research. It also investigates the financial impact on the healthcare system of improving substitute decision-making.Methods/DesignDyads (n = 240) comprising an older adult and his/her self-selected proxy are randomly allocated to the experimental or control group, after stratification for type of designated proxy and self-report of prior documentation of healthcare preferences. At baseline, clinical and research vignettes are used to elicit older adult preferences and assess the ability of their proxy to predict those preferences. Responses are elicited under four health states, ranging from the subject's current health state to severe dementia. For each state, we estimated the public costs of the healthcare services that would typically be provided to a patient under these scenarios. Experimental dyads are visited at home, twice, by a specially trained facilitator who communicates the dyad-specific results of the concordance assessment, helps older adults convey their wishes to their proxies, and offers assistance in completing a guide entitled My Preferences that we designed specifically for that purpose. In between these meetings, experimental dyads attend a group information session about My Preferences. Control dyads attend three monthly workshops aimed at promoting healthy behaviors. Concordance assessments are repeated at the end of the intervention and 6 months later to assess improvement in predictive accuracy and cost savings, if any. Copies of completed guides are made at the time of these assessments.DiscussionThis study will determine whether the tested intervention guides proxies in making decisions that concur with those of older adults, motivates the latter to record their wishes in writing, and yields savings for the healthcare system.Trial RegistrationISRCTN89993391.

Resumen En el siguiente artículo se ofrece un análisis del denominado “diario de Gilleleje” del filósofo danés Soren Kierkegaard. Se intenta argumentar que en este escrito temprano de 1835 y de un carácter eminentemente literario es posible encontrar las reflexiones filosóficas incipientes de un joven Kierkegaard acerca de la cuestión existencial del descubrimiento del propio Yo y la construcción de la personalidad, uno de los temas fundamentales en la obra del escritor danés. El desarrollo del texto culmina con la exposición (...) de uno de los conceptos claves del pensamiento kierkegaardiano: la verdad subjetiva.In the following article I offer an analysis of the so-called “journal of Gilleleje” by Danish philosopher Soren Kierkegaard. I would like to argue that in this early writing of 1836, a piece with a distinct literary tone, it ispossible to observe young Kierkegaard’sfirstphilosophi- cal insights on the existential question about the discovery of the self and the development of personhood, one of the key topics in the Dane's writings. The journal concludes with the exposition of a central concept in Kierkegaard’s thought: subjective truth. (shrink)
