A través de una reconstrucción de la evolución de su pensamiento, en este artículo se estudia la utilización de infinitesimales por parte de Newton. Se distingue entre dos concepciones sucesivas de lo que denominó momento. A la primera de estas entidades la caracterizó como un infinitesimal, pero a la segunda (un indivisible generador de magnitudes finitas, que interviene en su método de las primeras y últimas razones) no la consideró corno tal. Se entiende así su manifestación de rechazo a los (...) infinitesimales, formulada en una segunda etapa, y se ve que las dudas arrojadas por algunos investigadores sobre la veracidad de tal manifestación se deben a una determinada interpretación de esta última concepción de momento.

This paper argues that the normative character of our unreflective situated behaviour is not factual. We highlight a problematic assumption shared by the two most influential trends in contemporary philosophy of cognitive science, reductionism and enactivism. Our intentional, normative explanations are referential, descriptive or factual. Underneath this assumption lies the idea that only facts can make true or false our attributions of cognitive, mental and agential abilities. We will argue against this view by describing the main features and problems of (...) reductionism and enactivism and then we will offer two arguments against this shared factualist assumption: (1) normative vocabulary is ineliminable if we want a complete explanation of our situated practices; and (2) the factualist assumption is a species of the is-ought fallacy. Finally, we will claim that a folk psychological explanation of our normative practices is fully compatible with ontological naturalism when such descriptivist or factualist assumption is rejected.

In this paper, we analyze the origin of the links between global bioethics (which we differentiate from biomedical bioethics) and human rights. We understand that we are in a global civilizational crisis, whose roots extend to 1492 today, in which the modern-capitalist model used the discourse of human rights to justify its predatory technocracy. There are three theoretical assumptions that support our analysis: 1) The current conditions in which the technique shows its destructive power over nature (Anthropocene) indicate that none (...) of the ethical antecedents are applicable to such circumstances. In this new context, the kantian categorical imperative has been reconverted into a moral and political duty to not instrumentalize either human beings or nature. We call this new ethical consideration bioethics. 2) The current geopolitical composition of the world must be thought in terms of the global North and the global South, as two regions that are forged in the midst of important processes of globalization of the world-system, and whose main consequence lies in the absence of equity in the distribution of wealth and well-being between the two. 3) The current environmental crisis or climate change, the product of an economic model based on extractive technology, has become one of the most serious threats against human rights.

ABSTRACTPrior research has found a relationship between perceived facial attractiveness and perceived personal trustworthiness. We examined the time course of attractiveness relative to trustworthiness evaluation of emotional and neutral faces. This served to explore whether attractiveness might be used as an easily accessible cue and a quick shortcut for judging trustworthiness. Detection thresholds and judgment latencies as a function of expressive intensity were measured. Significant correlations between attractiveness and trustworthiness consistently held for six emotional expressions at four intensities, and neutral (...) faces. Importantly, perceived attractiveness preceded perceived trustworthiness, with lower detection thresholds and shorter decision latencies. This reveals a time course advantage for attractiveness, and suggests that earlier attractiveness impressions could bias trustworthiness inferences. A heuristic cognitive mechanism is hypothesised to ease processing demands by relying on simple a... (shrink)

I defend a Deferred Ostension view of quotation, on which quotation-marks are the linguistic bearers of reference, functioning like a demonstrative; the quoted material merely plays the role of a demonstratum. On this view, the quoted material works like Nunberg’s indexes in his account of deferred ostensión in general. The referent is obtained through some contextually suggested relation; in the default case the relation will be … instantiates the linguistic type __, but there are other possibilities. In this way, the (...) deferred ostension view deals with a problem I pointed out for the identity proposal in my earlier work, that we do not merely refer with quotations to expression-types, but also to other entities related in some way to the relevant token we use: features exhibited by the token distinct from those constituting its linguistic type, features exhibited by other tokens of the same type but not by the one actually used (as when, by using a graphic token, we refer to its phonetic type), or even other related tokens (see the examples on p. 261 of García-Carpintero 1994).

Alternative splicing (AS) is a widespread mechanism with an important role in increasing transcriptome and proteome diversity by generating multiple different products from the same gene. Evolutionary studies of AS have focused primarily on the conservation of alternatively spliced sequences or of the AS pattern of those sequences itself. Less is known about the evolution of the regulation of AS, but several studies, working from different perspectives, have recently made significant progress. Here, we categorize the different levels of AS evolution, (...) and summarize the studies on evolution of AS regulation, which point to a high level of evolutionary conservation of the regulation of AS events conserved between related species. This suggests that the quantitative regulation of AS is an intrinsic part of AS function. We discuss the potential role of changes in developmental regulation of AS as an additional layer in complex gene regulatory networks and in the emergence of genetic novelties. (shrink)

The distinction between personal level explanations and subpersonal ones has been subject to much debate in philosophy. We understand it as one between explanations that focus on an agent’s interaction with its environment, and explanations that focus on the physical or computational enabling conditions of such an interaction. The distinction, understood this way, is necessary for a complete account of any agent, rational or not, biological or artificial. In particular, we review some recent research in Artificial Life that pretends to (...) do completely without the distinction, while using agent-centred concepts all the way. It is argued that the rejection of agent level explanations in favour of mechanistic ones is due to an unmotivated need to choose among representationalism and eliminativism. The dilemma is a false one if the possibility of a radical form of externalism is considered. (shrink)

There seems to be a distinction between primary and secondary properties; some philosophers defend the view that properties like colours and values are secondary, while others criticize it. The distinction is usually introduced in terms of essence; roughly, secondary properties essentially involve mental states, while primary properties do not. In part because this does not seem very illuminating, philosophers have produced different reductive analyses in modal terms, metaphysic or epistemic. Here I will argue, firstly, that some well-known examples fail, and (...) also that there are deep reasons why such approaches should do so. Secondly, I will argue that it is acceptable to remain satisfied with the non-reductive account in terms of essence. To that end, I will indicate how such an explication could be put to use to support the claim that properties like colours and values are secondary. In a series of recent writings, Kit Fine has argued that essence cannot be reductively analysed in modal terms. Fine offers some examples to motivate his claim. I suggest that the primary/secondary distinction constitutes a philosophically interesting illustration. (shrink)

Citizen science is growing quickly, given its potential to enhance knowledge coproduction by diverse participants, generating large and global data sets. However, uneven participation in CS is still an important concern. This work aims to understand participation dynamics in CS and how they are shaped by participation barriers and drivers. We do so by examining participation in CONECT-e, a CS project that uses a wiki-like platform to document traditional ecological knowledge. More precisely, we analyze quantitative data on participants’ profile and (...) activity patterns and qualitative data on barriers and drivers of participation. Our findings suggest that overcoming the education, age, and residence participation barriers is challenging even in cocreated CS projects. This is potentially due to issues of perceived self-illegitimacy and low access to information and communication technologies. Our results also point out that participants’ alliance with the project’s objectives and trust relationships with the project team are important drivers of participation in CS projects. Finally, we also highlight the need to think beyond participation as single actions and rather consider participation diversity in CS as functional diversity in ecosystems, with participants performing a diverse set of interconnected tasks or functions.

At the beginning, the poetry was considered as the genesis of the arabic art, and after then the prose of adab, both of them appeared with the idea of the "beauty science". This idea would be projected on the music. On the other hand, the greek heritage of the classic arabic philosophy legacy was reflected during the first manuscripts of the arabic philosophers and musical theoreticians as al-Kindf and al-Farabf, as a result appeared a new conception of the "beauty" and (...) "aesthetic". By this way, taking as a point of reference the greek classical world, the new parameters would appear as an result of this own reality and idiosyncrasy. Their poetry and musical legacy, joined to the philosopher and religious mind would complete the work of the "aesthetic musical art". The study of the arabic middle music prove that the harmony in the poetry, lingüistic and rhitmycal contents, go in parallel with the melodic content until it reached a harmonic relation and in definitive cosmic, and as a result an "aesthetic ideal". This ideal was based on "beauty" and the "aesthetic emotion" produced by the art and all that as reflet to the harmonic until the corp and the spirit and oriented to the spherical work and to the divinity.

This paper offers a rejoinder to an argument by Schiffer against semantic accounts of vagueness (typically relying on supervaluationist techniques) based on indirect discourse. The argument, as far as I know original with Schiffer, occurs in “Two Issues of Vagueness” (Schiffer 1998). It is not addressed at supervaluationism as such, but at the philosophical account of vagueness which typically relies on it. Supervaluationism is not by itself a theory, but a logical technique with several applications. In one such application, supervaluationism (...) serves to alleviate a tension between, on the one hand, the rejection of bivalence for some utterances which characterizes what I take to be the correct view on vagueness (vagueness as semantic indecision – ‘VSI’ henceforth –, to put it in the terms of a well-known defender of the view, David Lewis), and, on the other, well-established facts about the semantics of logical expressions. I will address Schiffer’s argument by putting forward some considerations on the concept of de re thoughts which I take to undermine it. These considerations are not ad hoc, but highly germane to VSI; or so I will try to show. (shrink)

José Luis Moreno argumenta contra lo que considera una variedad de formas de fetichismo político. Lo que tienen en común es depositar una confianza excesiva o monolítica en algún mecanismo democrático en particular. Compartimos su motivación y en esta nota crítica intentamos llevar sus argumentos más lejos preguntándonos si diferentes tipos de conocimiento políticamente relevante pueden distinguirse, si en algunos contextos es necesario dejar las decisiones en manos de expertos y si la propuesta de Moreno cae en un nuevo tipo (...) de fetichismo con respecto al sorteo como mecanismo capaz de eliminar injusticias sociales profundas.

An important part of Aristotelianism has revolved around the different interpretations given to the famous fifth chapter of Aristotle’s De Anima lll. The brevity with which he spoke about an intellectual agent principle described as divine and everlasting has led to a lengthy debate between those who argue that this principle is part of the individual soul and those who think that it must be placed outside the individual intellectual powers. Among the latter, the interpretation of the Renaissance Aristotelian Giacomo (...) Zabarella, a great expert on classical Greek and Aristotle’s works, is still one of the most influential. (shrink)

El presente artículo reconoce que las dos grandes metodologías de Foucault (la arqueología y la genealogía) surgieron en dos momentos diferentes de su enfoque metodológico, y argumenta que a partir de la década del setenta se desarrolla el concepto de dispositivo en el filósofo debido a una discontinuidad en su investigación. Se sostiene que este problema surgió a raíz de una serie de situaciones: el descubrimiento de un nuevo problema de investigación y su relación con la ocurrencia de una coyuntura (...) sociopolítica especifica (fracaso de las movilizaciones sociales del mayo francés en 1968). Lo anterior llevó a Foucault a plantear la pregunta por ¿cómo se ejerce el poder y cuál es su relación con el saber?, en lugar del antiguo interrogante sobre ¿qué es el poder? Esta transformación de la pregunta resultó fundamental en Foucault, ya que le permite concluir que todo dispositivo presupone la existencia de un poder y que todo poder se ejerce mediante la utilización de un saber. El artículo se cierra con una referencia a Jurgen Habermas, autor que precisa la crisis que generó en Foucault el fracaso de las movilizaciones sociales ocurridas durante el denominado mayo francés. El presente trabajo se elaboró a partir de un método de investigación cualitativa y una técnica de rastreo bibliográfico. (shrink)

This paper argues for a conditional claim concerning a famous argument—developed by Church in elucidation of some remarks by Frege to the effect that the bedeutung of a sentence is the sentence’s truth-value—the Frege–Gödel–Church argument, or FGC for short. The point we make is this :if, and just to the extent that, Arthur Smullyan’s argument against Quine's use of FGC is sound, then essentially the same rejoinder disposes also of Davidson's use of FGC against ‘correspondence’ theories of truth. We thus (...) dispute a contention by Professor Davidson that it is coherent to accept that Smullyan’s rejoinder takes away the force of Quine’s version of FGC, while still consistently using FGC to establish that if true sentences (or utterances) correspond to anything, they all correspond to the same thing. We show that the differences between the cases discussed by Smullyan and Davidson’s version of FGC on which Davidson relies for his contention are irrelevant to the point under dispute. (shrink)

It is common to criticize the idea of objectivity by claiming that we cannot make sense of any cognitive contact with the world that is not constituted by the very materials of our thinking, and to conclude that the idea must be abandoned and that the world is ‘well lost’. We resist this conclusion and argue for a notion of objectivity that places its source within the domain of thoughts by proposing a conception of facts, akin to McDowell’s, as thinkable (...) while independent of any act of thinking. However, we do so without any empiricist commitment. (shrink)
