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.

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.

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.

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)

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.

We argue that philosophers are competent to facilitate public discussion concerning restrictions on human migration across political borders. We also argue that presenting public audiences with a prima facie case for open borders offers a unique opportunity to elucidate important aspects of philosophical reasoning. Finally, we share resources and a lesson plan for those keen to examine the case for open borders with students, or to facilitate public discussion on these issues.

Este ensayo describe una particular experiencia estética, basada en la obra gráfica La confianza, de Goya, perteneciente a la serie de los Caprichos e invenciones, que son paisajes de pesadilla que ilustran la crisis social de la época de las Luces. Desde aquí, desarrollaré una hermenéutica personal que avanza por tres escenarios teóricos sobre lo que implicaría la confianza de una mujer en otra, a partir del soporte de imagen. Las diversas tesis teóricas se sitúan en la órbita del pensamiento (...) feminista de actualidad y en donde se representarán a tres autoras: Muraro, Despentes y Braidotti. Finalmente, este dispositivo de interpretación permitirá relevar el arte de Goya a propósito de una posible revisión de crítica social sobre la virtud de la confianza. (shrink)

The aim of this work is to end the debate about the widespread acceptance among specialists, that the 6th century Byzantium treatise by Cassianus reached Muslim scholars by means of two routes: a translation from Greek into Arabic and the other translation by means of a Persian translation. Thanks to a comparison of the texts, one can prove beyond all doubt that there was only a secondary translation route into Arabic from the Persian version. Additionally, this work highlights the significant (...) influence of the Fila[hdotu]arumiyya on the Andalusian agronomy. The most influenced subjects are pointed out and those agronomic sources derived from this treatise and the 10th century Greek Geoponica are studied. This study allows us to conclude that the later work was never translated into Arabic, therefore, the Andalusian agronomists only had access to the Arabic versions of Anatolius and Cassianus to which the Pseudo-Qus[tdotu]us' work was later added.

En su exposición Marcelo Boeri aborda el problema de la “utopía” política de Platón a partir de una reconstrucción argumentativa según la cual el significado del “ser posible” de la “ciudad ideal” descrita en la República puede ser comprendido a partir del recurso a la relación entre el paradigma y su copia. Sin embargo, la siguiente consideración, no se centrará en una evaluación de esta estrategia hermenéutica, sino, más bien, en ciertas suposiciones y afirmaciones que resultan difícilmente aceptables o, al (...) menos, muy discutibles. Esto es importante, puesto que, en cierto modo, el enfoque total del problema pierde claridad. (shrink)

RESUMEN Este artículo pretende comprender la filosofía de Platón como un ejercicio esencialmente político. Esto implica, sin embargo, distinguir cómo se ejerce esta filosofía política, su sentido y alcance. Muchos estudiosos han atribuido a Platón el proyecto político que Sócrates desarrolla en la República. Sin embargo, el símil de la caverna da cuenta de la imposibilidad o, al menos, de la interna problematicidad de tal proyecto, por lo cual se sugiere que no es en el diálogo República donde se encontraría (...) la auténtica filosofía política de Platón, sino en los denominados diálogos aporéticos. En estos diálogos no se habla sobre una posible ciudad, sino que se ejercita de manera viva una política desarrollada por la dialéctica terapéutica de Sócrates, cuya tarea es desvelar la virtud mediante el desenmascaramiento de los rostros de la ciudad. ABSTRACT The following paper contends that Plato's philosophy is essentially a political activity. This imply, however, to distinguish how this political philosophy carries out, its meaning and scope. Many scholars have attributed to Plato the political project, which Socrates develops in the dialogue Republic. Nevertheless, the simile of the cave reveals the impossibility of such a project or, at least, the serious problems that lie behind it. So, I suggest, that is not in the dialogue Republic where it finds Plato's authentic political philosophy, but in the so-called aporetic dialogues. In these dialogues it does not discuss about a possible city, but it exercises in a lively way a politics builted by Socrates' dialectic therapy, whose task is unveiling the virtue through the unmasking the faces of the city.

Dentro del contexto histórico de la sociedad tecnológica parece urgente considerar los alcances insólitos y los problemas éticos que suscita la provocación técnica actual, los cuales mueven a poner en cuestión la provocación productiva que el hombre ejerce respecto de la naturaleza. Sin embargo antes de tal cuestionamiento es necesario encontrar una vía de acceso a la esencia originaria de la técnica. Este artículo propone un camino de comprensión de la técnica a partir del sentido de la ποíησις según el (...) pensamiento de Platón, en cuyo “Banquete” puede extraerse cómo la τέχνη, en vez de ejercer una producción provocante, depende ella misma de la provocación de la naturaleza. According to the historical context of technological society, it seems urgent to consider the unusual scope and the ethical issues raised by the present technological provocation, which lead to questioning the productive provocation which man exerts over nature. Nevertheless before such questioning takes place, it is necessary to access the primary essence of technique. This paper sets a path for the comprehension of technique starting from the meaning of ποíησις based on Plato’s ideas. In his work "Symposium", technique emerges as τέχνη, which instead of exerting a provocative production, depends on the provocation of nature. (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.

Resumen: El presente trabajo intenta analizar los elementos críticos a la base de aquella suerte de prescripción que Edward Said formulara a los intelectuales bajo la célebre consigna de “decir las verdades al poder”, esto es, de interpelar públicamente al poder -político, económico, religioso, militar- frente a toda evidencia de injusticia, inconsistencia o turbia manipulación en su operar. En tanto tal, y a partir de nuestra lectura de Said, delimitamos cinco dilemas que el intelectual ha de resolver, en tanto requisitos (...) para decir las verdades al poder: orientación intramundana versus extramundana, rol profético versus sacerdotal, libertad universalista versus organicidad, racionalidad sustantiva versus instrumental y arrojo versus temor. Se comentan las implicaciones de estos dilemas a la luz de los desafíos y oportunidades que las sociedades contemporáneas -en particular, las latinoamericanas- presentan para el rol del intelectual.: This work analyzes the critical foundations of that quasi-rule posed by Edward Said to intellectuals through the famous motto “speaking truth to power”, that is, of publicly interpellating to power -political, economic, religious, military- whenever its exercise may involve injustice, inconsistency or underhanded manipulation. So, according to our interpretation of Said’s work, we identify five dilemmas the intellectual should resolve in order to be able to speak truth to power: a worldliness orientation versus an otherworldliness one, a prophetic role versus a priestly one, universalist freedom versus organic compromise, a substantive rationality versus an instrumental one, and courage versus fear. Involvements of these dilemmas are discussed according to the challenges and opportunities posed by current societies -in particular, the Latin American ones- to the intellectual’s role. (shrink)

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.

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)

The aim of this study was to explore the note-taking experiences of university students using paper-based and paperless resources. By means of a hermeneutic phenomenological approach, the note-taking experiences of 18 students from an international program at a university in Belgium were examined throughout a semester. In order to document these students’ practices with paper-based and paperless resources, four data collection methods were used: in-depth interviews observations focus group discussions and document analysis of students’ lecture notes. The results showed that (...) students experience note-taking as a complex phenomenon in which lived body, lived human relations, lived space and lived time come into play, and in which they try to find a balance between multiple engagements, between autonomy and authority, between attention and distraction, and between being original and mirroring others. This struggle for balance occurs irrespective of which medium they choose to use. These results provide an in-depth view of the phenomenon, and also highlight the complexity of the note-taking experience. (shrink)

ObjectivesTo investigate which of two sources of information about an older adult’s wishes—choices made in an advance directive or proxy’s opinion—provides better insight into the older adult’s preferences measured in hypothetical clinical situations involving decisional incapacity.MethodsSecondary analyses of data collected from 157 community-dwelling, decisionally competent adults aged 70 years and over who attended a group information session on advance directives with their proxy. Older adults were invited to complete a directive introduced during the session, designed to express healthcare preferences. An (...) average of 3 months later, older adults were asked during an interview whether they would want to receive each of four medical interventions and what their goals of care would be should they develop one of three sudden health events, assuming that they had severe dementia. Proxies were asked to guess the older adult’s answers in each of the seven scenarios.ResultsEighty per cent of the older adults completed the directive. Choices they made in the directive were more in line with the preferences they stated during the interview than were their proxies’ guesses at their answers. However, concordance was relatively low, with percentages of agreement ranging from 43% to 83% across scenarios.ConclusionsFindings suggest that a directive might provide better insight into a person’s wishes than the person’s proxy, although neither source is perfect. A multifaceted decision-making model that includes both sources of information might better serve the interests of older adults who have lost the capacity to make decisions on their own.Trial registration numberISRCTN89993391; Post-results.

In this paper, I present an interpretation of Kant’s view that reason’s hypostasis of the idea of a sum-total of reality is dogmatic and illegitimate. In the section on the ‘Transcendental Ideal’, the second section of the Ideal of Pure Reason chapter in the Critique of Pure Reason, Kant starts by describing reason’s procedure from the affirmation of the principle of thoroughgoing determination to the hypostasis in question. According to the interpretation I defend, the argument for hypostasis deployed in this (...) section constitutes an improvement upon an argument defended by the pre-critical Kant himself in his 1673 essay “The Only Possible Argument in Support of a Demonstration of the Existence of God”. By making reference to the concept of omnitudo realitatis, the argument in the ‘Transcendental Ideal’ section presents a much more radical and convincing interpretation of the thesis that ‘possibility presupposes actuality’. Second, I present transcendental idealism and its related distinction between objects of sense and objects in general as the main dissuasive argument of the critical philosopher against hypostasis. Finally, I consider an argument against hypostasis that is independent of transcendental idealism: the threat of set-theoretical paradoxes if we hypostatize the relevant idea, intended as the concept of an absolutely comprehensive totality.

La presencia de Platón y del pensamiento platónico se ha mantenido de manera incesante a lo largo de la historia de la cultura. En esta historia, el siglo XX refleja el rechazo y la aceptación, la recepción, en suma, de un modo inusitado tal vez porque, durante este siglo, la humanidad se vio cara a cara con los infiernos que supo crear: un mundo en ruinas hacía imposible intuir la perfecta quietud de las Formas. La recepción de Platón en el (...) siglo XX bucea en la recepción de Platón en aquel mundo contradictorio: ¿cómo se integra su pensamiento fundacionalmente metafísico con la deconstrucción de la metafísica? ¿Cuáles son los alcances de la crítica que la teoría política hace, desde la época de los totalitarismos, al autor de la República? ¿Qué valor cognoscitivo y pedagógico puede tener en mito platónico para filósofos cristianos que se ocupan del pensamiento platónico? ¿Cómo recibe la poesía hispanoamericana su voz de demiurgo? Estas preguntas, de las que se ofrecen diversas respuestas en este libro, son tratadas con rigor académico y confrontadas doblemente con las fuentes: en primer término, con Platón y luego con quienes son estudiados en el presente volumen, aunque desde ángulos muy diversos: M. Heidegger, H. G. Gadamer, K. Popper, E. Cassirer, L. Marechal. La seguridad del tratamiento metodológico y lingüístico que se refleja en esta obra hace que sea altamente recomendable para alumnos de grado y de posgrado en Filosofía, Teoría Política, Literatura y Humanidades en general.

This paper explores the connection between Kant’s first antinomy and the set-theoretical paradox of the largest cardinal. The lesson to be drawn is that we should refrain from reifying the collections that generate the antinomies: the collection of all spatio-temporal objects in the case of Kant’s first antinomy, the collection of all objects whatsoever in the case of the Cantorian paradox. This conclusion is not only one that we are entitled to draw but also one that does not generate new (...) philosophical problems of its own. In this respect it is more attractive than other contemporary reactions to the paradoxes of set theory. (shrink)
