The paper presents color as a case study for the analysis of phenomena that pertain to several levels of reality and are typically framed by different sciences and disciplines. Color, in fact, is studied by physics, biology, phenomenology, and esthetics, among others. Our thesis is that color is a different entity for each level of reality, and that for this reason color generates different observables in the epistemologies of the different sciences. By analyzing color as a paradigmatic case of an (...) entity naturally spreading over different levels of reality, the paper raises the question as to whether making explicit the usually implicit ontological assumptions embedded within the different observables exploited by the different sciences may eventually clarify some of the difficulties of developing a comprehensive theory of color.

A recent report from the UN makes the case for “global data literacy” in order to realise the opportunities afforded by the “data revolution”. Here and in many other contexts, data literacy is characterised in terms of a combination of numerical, statistical and technical capacities. In this article, we argue for an expansion of the concept to include not just competencies in reading and working with datasets but also the ability to account for, intervene around and participate in the wider (...) socio-technical infrastructures through which data is created, stored and analysed – which we call “data infrastructure literacy”. We illustrate this notion with examples of “inventive data practice” from previous and ongoing research on open data, online platforms, data journalism and data activism. Drawing on these perspectives, we argue that data literacy initiatives might cultivate sensibilities not only for data science but also for data sociology, data politics as well as wider public engagement with digital data infrastructures. The proposed notion of data infrastructure literacy is intended to make space for collective inquiry, experimentation, imagination and intervention around data in educational programmes and beyond, including how data infrastructures can be challenged, contested, reshaped and repurposed to align with interests and publics other than those originally intended.

By executive order—later passed into law—President Obama closed legal loopholes used to justify torture by his predecessor. Less often discussed, his administration also instituted scientific research into the most effective interrogation techniques. This dual-track approach already demands the use of two different methods to properly discuss the policy, and in this article, a third is put forward for a fuller interdisciplinary view. That is to say, although there are notable shortcomings, scientific and legal developments will be explored to illuminate how (...) he also clarified a moral stance for the nation. Put all together, this article will show that Obama indeed achieved laudable steps towards preventing the reintroduction of torture. (shrink)

Octavio Paz fue un lúcido intérprete de su siglo. Este trabajo explora aspectos decisivos de su propia definición como poeta y ensayista, así como de su trayectoria creativa y crítica, altamente representativa de las transformaciones del artista y el escritor contemporáneos. Los ecos de sus experiencias, prácticas de sociabilidad y lecturas, unidos a su sensibilidad y lucidez, hicieron que ya desde sus primeros textos en prosa Octavio Paz contribuyera a la reconfiguración del ensayo como género. Proponemos leer algunos textos del (...) escritor mexicano en diálogo con las reflexiones de varios de los grandes refundadores del ensayo y la crítica en el siglo XX. Su búsqueda de una comunicación profunda entre poesía e historia, su esfuerzo por repensar críticamente la tradición, su exigencia de autenticidad y libertad en el quehacer del escritor, son algunos de los elementos que dieron lugar en sus ensayos a una nueva poética del pensar y a una nueva relación entre conciencia y transparencia.

The Author argues for a non-semantic theory of intentionality, i.e. a theory of intentional reference rooted in the perceptive world. Specifically, the paper concerns two aspects of the original theory of intentionality: the structure of intentional objects as appearance (an unfolding spatio-temporal structure endowed with a direction), and the cognitive processes involved in a psychic act at the primary level of cognition. Examples are given from the experimental psychology of vision, with a particular emphasis on the relation between phenomenal space (...) and colour appearances. (shrink)

Cyclin‐dependent kinases are Ser/Thr protein kinases best known for their cell cycle roles, where CDK1 triggers mitotic onset in all eukaryotes. CDKs are also involved in various other cellular processes, some of which, such as transcription and centrosome duplication, are coupled to cell cycle progression. A new study suggests that the mitotic CDK network is active at low levels in non‐dividing, differentiating precursors of multiciliated cells, and that it drives ciliogenesis. Manipulating the activity of CDK1 or PLK1 altered transitions between (...) the amplification, growth, and disengagement phases, in a manner analogous to the control of passage through different phases of mitosis. How the dynamics of the mitotic kinase network are controlled in these post‐mitotic cells, and whether other cell cycle regulators are also involved, remains unknown. In the present mini‐review we suggest that the redeployment of cell cycle regulators to control steps of differentiation in non‐dividing cells might be a more general, hitherto under‐recognized, feature of cell regulation.

_El espejo enterrado_ (1992) ocupa un lugar clave en la producción ensayística del escritor mexicano Carlos Fuentes y lo confirma como uno de los más notables intelectuales de nuestro tiempo. La obra y la serie documental a ella vinculada se reprodujeron ampliamente para contribuir a la reflexión en torno al significado de los quinientos años del primer viaje de Colón a través del Océano Atlántico, así como también para pensar la posibilidad de una comunidad iberoamericana apoyada en una historia, una (...) lengua, una tradición cultural y un imaginario compartidos. Este ensayo de interpretación de la vida de América y España se piensa a su vez como una biografía de nuestra cultura y una autobiografía intelectual del propio autor. Fuentes encontró en un año tan significativo como 1992 una oportunidad dorada para escribir la biografía de una cultura que consideró unida por el que llamó “Territorio de la Mancha”, repensar la relación entre España y América y emprender una nueva valoración de su perfil, su destino y su aporte al concierto de las naciones en una nueva etapa del orden mundial.

Involutive Stone algebras were introduced by R. Cignoli and M. Sagastume in connection to the theory of $n$-valued Łukasiewicz–Moisil algebras. In this work we focus on the logic that preserves degrees of truth associated to S-algebras named Six. This follows a very general pattern that can be considered for any class of truth structure endowed with an ordering relation, and which intends to exploit many-valuedness focusing on the notion of inference that results from preserving lower bounds of truth values, and (...) hence not only preserving the value $1$. Among other things, we prove that Six is a many-valued logic that can be determined by a finite number of matrices. Besides, we show that Six is a paraconsistent logic. Moreover, we prove that it is a genuine Logic of Formal Inconsistency with a consistency operator that can be defined in terms of the original set of connectives. Finally, we study the proof theory of Six providing a Gentzen calculus for it, which is sound and complete with respect to the logic. (shrink)

The paper examines the contours, features and developments of two faces of pluralism, as well as their interactions. First of all, based on the analysis of the pluralist theories, it underlines that pluralism is not perceived now only as a particular American school of thought, but mostly as a generic concept with meanings and connotations that vary from one epoch to another. Second of all, it scrutinizes the political pluralism in the United States, more exactly the relationship between constitutional pluralism (...) and party pluralism, as well as the pluralism of interest groups. The religious pluralism is seen both as denominational pluralism and as diversity of religious organizations. The paper shows that, in spite of the common ground in the constitutional provisions and much interference in their development, each of the two faces of pluralism has followed its own dynamics. Next, it focuses on the new religious pluralism, which has nourished controversies regarding its effects on democracy in America. Although prestigious scholars have warned that these new challenges face real perils, the author of this paper sides with those who see them less of a threat than an opportunity for democracy to develop new interactions and participative tools, without abandoning its principles and values.

This article aims at a reflection on the Marxist concept of Ideology as an attempt to understand the transposition from the conscience level to the physical corporality level accomplished by Michel Foucault, as a form of instituting disciplinary power over the individual and also as a means of domination which is more effective than conscience itself.Este artigo objetiva uma reflexão sobre o conceito marxista de ideologia, ao mesmo tempo em que busca entender a transposição do nível da consciência para o (...) nível da corporalidade física, feita por Michel Foucault, como forma de instituição do poder disciplinar sobre os indivíduos, como meio de dominação muito mais eficaz do que a própria consciência.

Entender la dimensión moral de la dietética en la antigüedad exige investigar los avances de las investigaciones médicas gracias a las cuales se establecen las bases de la psicología moral. Por esta razón en este artículo se exploran algunos pasajes de Sobre las opiniones de Hipócrates y Platón, escrito por el médico alejandrino Galeno de Pérgamo (I-II d. C). Según los hallazgos de su investigación sobre la naturaleza del alma, aun cuando ésta tuviera una sustancia propia, ajena a las mezclas (...) humorales del cuerpo, es preciso admitir que sus facultades, incluida la racional, pueden ser ayudadas o impedidas por el equilibrio o por el desequilibrio de los humores del cuerpo. Esta es la tesis que defenderá en su escrito de madurez titulado Las facultades del alma siguen los temperamentos del cuerpo. Para Galeno, como antes para Platón y Aristóteles, la forma de vida, que incluye la nutrición, incide en la salud y en la enfermedad del alma. En la tradición que le antecede ya se aceptaba la dimensión moral de la dietética, pero nuestra tesis es que en las investigaciones de Galeno sobre la fisiología de las facultades del cuerpo, encontramos el fundamento empírico para la afirmación según la cual el cuidado del cuerpo influye en la salud del alma.

The Neoplatonic commentaries on Aristotle’s works have always been considered somehow suspicious. That is partly related to the doctrinal commitments of the commentators, partly with the hermeneutical strategies to which they seem to recur. Both of these reasons have also give place to the accusation of distortion and misunderstanding of Aristotle’s philosophy. In the following paper I want to perform an exercise of disclosing the hermeneutical procedure that one of this commentators applies to one of the passages of the first (...) book of the De Anima. The commentator is Philoponus, the passage is the refutation of the soul-harmony theory. My aim is to show that, despite the doctrinal commitments that the commentator may have, his methodology follows Aristotelian guidelines. I hope that this could open perspectives on the value that the commentators must have as philosophers, rather than merely interpreters or paraphrasers. (shrink)

En medio de una sociedad que nos invita constantemente a la extroversión, cabe preguntarnos si el encuentro con nosotros mismos a través de una actitud “interior” y reflexiva no puede representar un factor clave para detener, en alguna medida, el proceso de deshumanización que descompone a Occidente.

Se busca rastrear la imagen que Platón tiene de Heráclito y articularla con la estructura argumentativa del Cratilo, para comprender las necesidades textuales a las que responde la doctrina del flujo perpetuo, es decir, la discusión sobre la corrección (ὀρθότης) del nombre.

Maurice Chappaz’s work, a monumental one under many aspects, offers the scholar a rich field for reading the landscape. For Chappaz, the Valais - his birthplace represents everything: landscape and spirituality, affectivity, source of life and of writing, engagement, recognition of the sense of the divine in the human being, in space and in the future, the first and supreme sense of becoming, source of life and of writing, ‘the vine and the bread of any existence’. Sedentary or homo viator, (...) the individual remains essentially linked to a place, to space. A relationship of mutual nourishing, of determination, even of transubstantiation is being created between the human being and space. The space is the man, it comes to life within the man who can only live in relationship with his native land, the matrix-space, equally ‘kingdom of God’ and work accomplished by men. (shrink)
