Priest's theory of motion is based on Leibniz's Continuity Condition (LCC), which states that any state that exists at each instant in a continuous set of moments also exists at its temporal limit. If we accept the CCL, a free-falling pen would have to be simultaneously in motion and at rest at the instant of change: the critical moment when it hits the ground, thus passing from the state of motion to that of rest. This seems to be a contradictory (...) state of affairs, which is precisely what Priest claims to be the case. In this article, I discuss the logical possibility of empirically testing whether such a contradictory state of affairs occurs. (shrink)

In this historical article, Newton da Costa discusses Francisco Miró Quesada’s philosophical ideas about logic. He discusses the topics of reason, logic, and action in Miró Quesada’s work, and in the final section he offers his critical view. In particular, he disagrees with Miró Quesada’s stance on the historicity of reason, for whom “reason is essentially absolute”, whereas for da Costa it “is being constructed in the course of history”. Da Costa concludes by emphasizing the importance of Miró Quesada’s theory (...) of logic and reason, despite it still being incomplete. -/- Historical article by Newton da Costa, annotated and translated by J.

Popper restricted his definition of falsifiability to consistent theories through what we may call his requirement of consistency. His main argument was that an inconsistent theory does not distinguish the sentences that corroborate it from those that contradict it, for all sentences follow from it. I propose to replace this requirement by the more basic requirement that the classes of potential corroborators and falsifiers of a theory do not overlap. This results not only in an unrestricted definition of falsifiability but (...) also in some inconsistent theories being falsifiable whenever that inconsistency is not located among its observational statements. Although this assumes a restriction of the principle of explosion or ex contradictione sequitur quodlibet (ECQ), it does not depend on any particular system or approach of paraconsistent logic. Finally, I propose to define the class of potential refuters of a theory, which is obtained by subtracting the class of potential corroborators from the class of potential falsifiers. Given that, by definition, the classes of potential refuters and corroborators of a theory do not overlap, it immediately follows that some observationally inconsistent theories are refutable in this sense. This establishes the bases for a new and more general formal theory of falsifiability of scientific factual/empirical theories. (shrink)

Célebre pintor do século XVIII, Joshua Reynolds apresentou ao longo dos anos 1769-1790 discursos para Royal Academy of Arts. Neles, expõe uma concepção de pintura que privilegia os quadros históricos. No entanto, o próprio Reynolds pratica a pintura de retratos. Analisar em que medida a feitura de retratos não entra em contradição com o argumento segundo o qual os quadros históricos são aqueles que melhor representam o gênero pictórico é o que se busca problematizar neste texto.

L'A. de cette étude analyse des textes inédits d'Hilaire de Poitiers où ce dernier parle de la réciprocité des relations trinitaires et de la mutuelle «interdépendance» du Père et du Fils. Il montre que l'insistance sur les relations originaires et sur les processions divines ne signifient pas nécessairement l'infériorité du Fils, et que si celui-ci n'existe qu'en totale référence au Père, de même ce dernier se réfère au Fils et ne peut exister sans lui.

The trinitarian theology of Karl Rahner has been the object of much discussion that has concentrated above all on two points: the «fundamental axiom» of the trinitarian theology and the problems surrounding the concept ofthe divine person. The fundamental axiom has helped to reclaim the central place of the mystery of the Trinity in the Christian faith and the need to set out from the economy of salvation as the only way to search more deeply into the mystery of God. (...) If the first part of the axiom, «the economic Trinity is the immanent Trinity», has been commonly accepted, the second, «and vice versa», has been the object of criticism. It must be emphasized in each case that the economy of salvation does not constitute or perfect the triune God and that He acts in it with full freedom. With these provisos, the second part of the axiom becomes not only legitimate but necessary to guarantee the universal mediation of Christ in whom God has reconciled the world to Himself. The concrete development of the trinitarian theology of Karl Rahner is not without its problems. It has been accused of tending toward modalism, in that the «personal» character of the divine hypostases in the immanent Trinity is much diminished. The article reviews the criticisms of various types that have been made and tries to offer a balanced interpretation of the thought of the German theologian that bears in mind its various aspects.

In the following pages, the main proposal is to indicate how Max Weber has dialogued directly with some prerogatives from Kant’s Critic of practical Reason, following the reception of Wilhelm Windelband’s concept of “responsibility” (Verantwortlichkeit) and his theory of values. In sight of these influences, in this paper will be argued how Weber adherence to the neo-Kantian value concept has made possible a review on the categorical imperatives, which has turned his reading from Kantian philosophy to the proposal of an (...) antinomy between the ethic of conviction and the ethic of responsibility inside the Kantian moral maxims. -/- Nessa abordagem será proposto que a recepção de Max Weber do conceito de “responsabilidade” (Verantwortlichkeit) de Wilhelm Windelband, bem como sua revisão de certos elementos da filosofia dos valores neokantiana do sudoeste da Alemanha, permitiram que Weber estabelecesse um diálogo mais direto com os pressupostos de Kant em sua Crítica da razão prática. Em vista dessas influências, o presente artigo argumentará que a maneira como Weber revisa os imperativos categóricos direcionou sua compreensão da filosofia kantiana pelo conceito de “valores”, o permitindo ainda, propor a existência de uma antinomia entre a ética da convicção e da responsabilidade no interior das máximas morais kantianas.

Voltaire has presented in his Letters on the English different themes, from religious ethics, literacy, politics, to dramas and science. The letters present us a comparison between England and France. In this parallel we shall present how Voltaire was concerned in evaluate a high standard of taste and refinements. This paper will review some of the last letters of those, which testify about this criterion of taste as a modern point of view. We shall present in Voltaire the eminence of (...) modernity in taste, refinements and on liberty of enjoying the ecstasies of a cosmopolitan life fulfilled with entertainments and luxury. We shall present how Voltaire fought against barbarism in benefit of civilization and some how against religiosity in benefit of an ethic hedonism. (shrink)

The tragic death in Tolstoy's writings has helped both Max Weber and György Lukács in characterizing the modern pathos as a tragic contemplation of the emptiness of life. Through Tolstoy's readings, Weber and Lukács found an interesting source of denying arts and modern sciences autonomy, considering, from the aesthetics sphere, the meaningless of this new immanent reality. Both has assumed Tolstoy main theme from the same perspective, contrasting ancient and modern worldviews. Max Weber presented this theme in his disenchantment of (...) world theory and Lukács, in a very similar way, following the paradox of religious needing as a mainline. -/- O tema da morte trágica, presente nos escritos de Liev Tolstói, auxiliou tanto a Max Weber como a György Lukács a caracterizarem o pathos moderno de pressentimento da morte como uma contemplação do vazio. Weber e Lukács encontraram, através das leituras de Tolstói, uma interessante maneira de questionar a autonomia da arte e da ciência moderna, considerando pela esfera estética, como se mostra sem sentido a recente realidade imanente. Ambos assumiram o tema central das obras de Tolstói segundo uma mesma imagem, derivada do contraste entre o mundo antigo e o moderno. Max Weber adequou esse tema a sua teoria do desencantamento do mundo e Lukács, de modo muito semelhante, seguindo seu conceito do paradoxo da necessidade religiosa. (shrink)

The body of information on the Internet is becoming increasingly geographical. This is both due to the expansion of established categories of geographic information and to the simultaneous enrichment of other types of information through geographic identifiers. As this repository of geographic information expands, it is also a key site for multiple processes of commodification transforming informational resources into market goods. Understanding the dynamics driving the integration of geographic information into the digital economy requires a comprehensive political economic analysis. A (...) key component of this analysis is to explain the logics of creation and allocation of economic value from geographic information on the Internet. Addressing this need, in the present article I deploy the property regimes schema developed by Schlager and Ostrom and expand it to elucidate the differentiated commodification processes of geographic information on the Internet. Property regimes are arrangements that define rules, distribute rights, and delineate roles with respect to particular goods. These arrangements are enabled by elements such as legal frameworks, jurisdictions, type of information, and technologies of access. In this article, I explore how the legal frameworks regulating traditional categories of geographic information have been destabilized in the process of technological innovation, leading to the creation of new informational goods along with their respective property regimes, and rearticulating legal, economic, and sociotechnical relations. To illustrate this, I analyze the case of Google Street View images through their property regimes in various jurisdictions. (shrink)

A growing number of people are relying on technologies like Google Maps not only to navigate and locate themselves in cartographic space but also to search, discover and evaluate urban places. While the spatial data that underlies such technology frequently appears as a combination of Google-created maps and locational information passively collected from mobile (GPS-enabled) devices, in this article we argue that for such systems to function as both useful tools for exploration for users and sources of revenue, users must (...) actively produce massive quantities of granular spatial data that would otherwise be significantly more difficult and expensive to collect. The production of this qualitative information about places constitutes significant unremunerated affective labour. In this article, we build on the tradition of feminist geographies, especially feminist and critical Geographic Information Systems (GIS), to examine how the labour done by gendered, raced and often classed members of a local community is alienated by Google (i.e. Alphabet, Inc.) to produce commodified spatial data/media in the Local Guides platform. We analyse how Google’s presentation of the platform hails women as care labourers—sharing their thoughts, feelings and knowledge of place for free in the name of supporting and caring for a community, however vaguely it may be constituted. At the same time, we argue that digital labour that produces the Local Guides platform draws from and reproduces specific gendering of spaces. We draw on a case study of a commercial corridor in the US city of Worcester, Massachusetts to show how the dialectic between affective digital labour and urban space has material effects on the production of raced, classed and gendered spaces and places. The article concludes with a call to maintain critical, feminist engagements with these types of platforms in order to further develop forms of digital praxis towards more just cities. (shrink)

We examine the extent to which host country income inequality influences multinational enterprises’ (MNE) expansion strategy for foreign production investment, depending on their specific strategic objectives. Applying a transaction cost framework, we predict that national income inequality has an inverted U-shaped relationship with foreign production investment. As inequality increases, MNEs accrue lower transaction costs arising from interactions with various local actors, leading to higher probability of investment. As income inequality increases further, its effect on location attractiveness will become negative, as (...) its attraction effect is increasingly offset by additional monitoring, bargaining, and security costs owing to the more fractious nature of high inequality societies. In addition, we suggest that the impact of income inequality is contingent on investment objectives: The inverted U-shaped relationship is stronger for efficiency-seeking investment but weaker for market-seeking and competence-enhancing investments. We find substantial support for our hypotheses through an analysis of 27 years (1986-2012) of data on Japanese MNEs’ overseas production entries. (shrink)

This work aims to rescue, transcribe and create new artistic and cultural expressions through the use of native peoples’ historical visual recordings, integrating intelligent technologies. For this purpose, a Chilean native peoples’ digital repository is collected, in order to apply a Digital Humanities-based methodology. From the chosen material, portraits are selected, recoloured through a AI-based model; the facial mesh is constructed using a facial landmark detector; the points of the mesh are reconstructed by a Delaunay triangulation; to finally apply an (...) additive manufacturing process. Thus, these physical pieces allow to compare the native people’s own physiognomies, creating new cultural expressions. (shrink)

This article analyzes the relation of the epistemological beliefs of students and teachers and the actions deployed in the classroom. The framework is the study of personal epistemology, which was developed, among other researchers, by Hofer, Pintrich and Schommer. The research method was, within the qualitative paradigm, through case studies, given the interest in describing the phenomenon in a specific scenario. The results show the epistemological beliefs of teachers and students, the events that make them evident and its relationship with (...) the behaviors shown in the classroom. The role of pedagogical beliefs as mediation between personal epistemology of educational actors and their practice are described and, finally, the relation between beliefs and educational practice is illustrated by analyzing specific class events and the justification expressed by teachers and students about their actions in the classroom.

We consider the concept of poverty from the asset-accumulation approach and propose an integrated framework, building upon existing theories, to describe how the interconnected factors of trust (or lack thereof) and social distance can reinforce poverty traps. Social distance is influenced by choice, while trust is the symptom that defines the strength of social ties on a group. We look at how an absence of trust influences how households make decisions about the use and accumulation of assets in ways that (...) could perpetuate poverty. Weak trust also affects how groups interact with each other in a society, creating “trust clusters” within homogeneous groups and antagonism across groups, which in turn affects aspirations and leads to an erosion of the basis of a social contract. For more effective and sustainable poverty reduction, we need to understand these linkages and address them systematically. (shrink)

In cybersecurity, there is a call for adaptive, accurate and efficient procedures to identifying performance shortcomings and security breaches. The increasing complexity of both Internet services and traffic determines a scenario that in many cases impedes the proper deployment of intrusion detection and prevention systems. Although it is a common practice to monitor network and applications activity, there is not a general methodology to codify and interpret the recorded events. Moreover, this lack of methodology somehow erodes the possibility of diagnosing (...) whether event detection and recording is adequately performed. As a result, there is an urge to construct general codification and classification procedures to be applied on any type of security event in any activity log. This work is focused on defining such a method using the so-called normalized compression distance (NCD). NCD is parameter-free and can be applied to determine the distance between events expressed using strings. As a first step in the concretion of a methodology for the integral interpretation of security events, this work is devoted to the characterization of web logs. On the grounds of the NCD, we propose an anomaly-based procedure for identifying web attacks from web logs. Given a web query as stored in a security log, a NCD-based feature vector is created and classified using a support vector machine. The method is tested using the CSIC-2010 data set, and the results are analyzed with respect to similar proposals. (shrink)

Sin embargo, Freud se limita a descubrir en la naturaleza humana un importante obstáculo del que el proyecto ilustrado no se podrá ya desentender. Este obstáculo, que afecta de un modo decisivo al modo como entender el paso a la mayoría de edad, remite a la existencia de un determinado reino de la heteronomía cuyo rasgo más (...) característico es su capacidad para suplantar la voz de la autonomía moral: al igual que la ley moral en Kant, el superyóuna vez ha interiorizado en la infancia y asumido como propios determinados contenidos de cultura.

En el planteamiento de Kant, el estado civil de derecho debe regirse exclusivamente por los mandatos de una legislación jurídica. La facultad de coaccionar (indisociable del derecho) no puede estar mezclada con nada ético. Sin embargo, en el presente artículo se trata de defender que, desde el propio planteamiento de Kant, la política en general (y, por lo tanto, también el desarrollo legislativo ordinario de cualquier sistema de derecho) resultan imposibles si no se supone cierta virtud cívica.

It is usual to read Freud as a critic of Enlightenment, specialy of the kantian way of thinking moral autonomy. However, all Freud did was discover in human nature a great difficulty that enlightenes philosophy just cannot ignore. This difficulty, which directly affects conceptions about the age of majority, refers to certain heteronomy mechanisms which main characteristic is the skill to supplant the voice of moral autonomy: exactly the same as moral law in Kant, super-ego -once internalized during childhood and (...) once culture imperatives have been assumed as one's own - orders without promising anythig or threatening anything . So, the political project of enthroning reason as the top authorithy depends on the existence of a republican organization that guarantees a pedagogical program for which "age of majoriry" does not mean any more naming "ego" to ancient customs internalized but the capacity of being ruled by one's own reason .Es frecuente buscar en Freud a un crítico de la Ilustración y, en particular, del modo de pensar la moral heredero del planteamiento kantiano.

The “transformation problem” in Marx’s Capital (how to make compatible the labour theory of value from the first book with “prices of production” from the third book) has been one of the main reasons to refute the marxist theory and, at the same time, a privileged matter in order to analyze the method question. In this paper, we try to analyze the sense and foundation of the labobour theory of value discussing with any attempt of reading Marx Capital as the (...) development of a supposed “dialectic method”. Analyzing the manuscripts and drafts that Marx did not finish, we try to defend that, contrary to what Engels thought (because it had been anounced by Marx himself), it is not possible to find in the third book a trace of the so expected “dialectic solution” to the “transformation problem”. That demands, of course, a different interpretation to explain the sense of the “transformation” of value into “production prices”. (shrink)

The goal of this article is to discuss several critical positions published recently in academic journals on the book The order of ‘Capital’, which aim is to lay the foundations for a republican reading of Marx’s major work. The core of the argument focuses against any attempt to derive normative proposals from scientific discoveries. From here, clarifying some key concepts and positions of the republican tradition is a necessary condition in order to show the close solidarity between Marx and Kant (...) about the formal and institutional conditions of any possible theory of justice.
