Large protein assemblies are usually the effectors of major cellular processes. The intricate cell homeostasis network is divided into numerous interconnected pathways, each controlled by a set of protein machines. One of these master regulators is the CCR4‐NOT complex, which ultimately controls protein expression levels. This multisubunit complex assembles around a scaffold platform, which enables a wide variety of well‐studied functions from mRNA synthesis to transcript decay, as well as other tasks still being identified. Solving the structure of the entire (...) CCR4‐NOT complex will help to define the distribution of its functions. The recently published three‐dimensional reconstruction of the complex, in combination with the known crystal structures of some of the components, has begun to address this. Methodological improvements in structural biology, especially in cryoelectron microscopy, encourage further structural and protein‐protein interaction studies, which will advance our comprehension of the gene expression machinery.

In this chapter, we discuss a selection of current views of the neural correlates of consciousness (NCC). We focus on the different predictions they make, in particular with respect to the role of prefrontal cortex (PFC) during visual experiences, which is an area of critical interest and some source of contention. Our discussion of these views focuses on the level of functional anatomy, rather than at the neuronal circuitry level. We take this approach because we currently understand more about experimental (...) evidence at this coarse level and because these results are appropriate for arbitrating between current theoretical frameworks. We discuss the Two-Visual-Systems Hypothesis (Milner & Goodale 1995; 2006), Local Recurrency (Lamme 2010; Lamme 2006), Higher Order (Lau 2008; Lau & Rosenthal 2011) and Global Workspace theories (Baars 1997; Baars 2005; Dehaene & Naccache 2001; Dehaene 2014). Despite the apparent stark differences between conscious and unconscious perceptual processing, available evidence suggests that their neural substrates must be largely shared. This indicates that the difference in neural activity between conscious and unconscious perceptual processing is likely to be subtle and highly specialized. We argue that current experimental evidence about the involvement of specific activity in prefrontal cortex supports the higher order neural theory of consciousness. In consequence, imaging techniques that focus only on marked differences between conscious and unconscious level of activity are likely to be insensitive to the relevant neural activity patterns that underlie conscious experiences. Finally, it follows from the evidence we discuss that the functional advantages of conscious over unconscious perceptual processing may be more limited than commonly thought. (shrink)

En el presente escrito, se da a conocer una interpretación _“personal”_, no por ello arbitraria, del texto _Sobre el concepto de historia _o _Tesis de filosofía de la historia_, _Über den Begriff der Geschichte_ de Walter Benjamín, leído de manera situada, una lectura cuya óptica pretende ser _desde_ América Latina. Se insistirá en la excepcionalidad crítica de la obra de Benjamín, sugiriendo que su propuesta alcanza una re-definición y transvaloración del concepto de historia, aquel que de manera habitual nos determina, (...) y que impide todo actuar, toda praxis revolucionaria, que para un tiempo como el nuestro, y que es ahora, se requiere más que nunca.

Introspection is a fundamental part of our mental lives. Nevertheless, its reliability and its underlying cognitive architecture have been widely disputed. Here, I propose a principled way to model introspection. By using time-tested principles from signal detection theory (SDT) and extrapolating them from perception to introspection, I offer a new framework for an introspective signal detection theory (iSDT). In SDT, the reliability of perceptual judgments is a function of the strength of an internal perceptual response (signal- to-noise ratio) which is, (...) to a large extent, driven by the intensity of the stimulus. In parallel to perception, iSDT models the reliability of introspective judgments as a function of the strength of an internal introspective response (signal-to-noise ratio) which is, to a large extent, driven by the intensity of conscious experiences. Thus, by modelling introspection after perception, iSDT can calibrate introspection’s reliability across a whole range of contexts. iSDT offers a novel, illuminating way of thinking about introspection and the cognitive processes that support it.

According to some evolutionary theorists human prosocial dispositions emerged in a context of inter-group competition and violence that made our psychology parochially prosocial, ie. cooperative towards in-groups and competitive towards strangers. This evolutionary hypothesis is sometimes employed in bioethical debates to argue that human nature and contemporary environments, and especially large-scale societies, are mismatched. In this article we caution against the use of mismatch theories in moral philosophy in general and discuss empirical evidence that puts into question mismatch theories based (...) on parochial prosociality. Evolutionary mismatch theories play at best a rhetorical role in these moral debates and may misrepresent the status of relevant evolutionary research. We finally recommend that moral philosophers interested in the evolutionary literature also engage with dispositions such as xenophilia and social tolerance to counterbalance the focus on psychological mismatches adopted so far.

Los grandes flujos migratorios globales que tuvieron lugar entre mediados del siglo XIX e inicios del XX vieron a cientos de millones de personas en todo el mundo cruzar la frontera de su país para ir a otro. En ese escenario, y a diferencia de otros países suramericanos, Colombia no fue un gran receptor de inmigrantes. Sin embargo, algunos de quienes llegaron, entre ellos judíos de distintos orígenes, enfrentaron restricciones para su ingreso al país, que fueron incrementándose particularmente en la (...) década de los años treinta, todo ello bajo gobiernos, en principio, de distintas vertientes ideológicas. Este artículo tiene el propósito de caracterizar los discursos, políticas y percepciones alrededor de la inmigración judía en Colombia durante las primeras cuatro décadas del siglo pasado, en el marco de una serie concepciones sobre cuestiones como la_ raza_ y la _nación_ y sus supuestas vinculaciones con las posibilidades de _progreso_.

Se propone la pertinencia de entender una parte sustancial de la historia humana desde una perspectiva (...) más amplia y diversa que intenta superar las habituales visiones eurocéntricas, como resultado de los contactos e intercambios producidos entre las personas y los grupos que conectan a distintas partes del mundo.

A recent turn in the cognitive sciences has deepened the attention on embodied and situated dynamics for explaining different cognitive processes such as perception, emotion, and social cognition. This has fostered an extensive interest in the social and ‘intersubjective’ nature of moral behavior, especially from the perspective of enactivism. In this paper, I argue that embodied and situated perspectives, enactivism in particular, nonetheless require further improvements with regards to their analysis of the social nature of human morality. In brief, enactivist (...) proposals still do not define what features of the social-relational context, or which kind of processes within social interactions, make an evaluation or action morally relevant or distinctive from other types of social normativity. As an alternative to this proclivity, and seeking to complement the enactive perspective, I present a definition of the process of moral sense-making and offer an empirically-based ethical distinction between different domains of social knowledge in moral development. For doing so, I take insights from the constructivist tradition in moral psychology. My objective is not to radically oppose embodied and enactive alternatives but to expand the horizon of their conceptual and empirical contributions to morality research. (shrink)

The study of social, ethical, and political issues from a naturalistic perspective has been pervasive in social sciences and the humanities in the last decades. This articulation of empirical research with philosophical and normative reflection is increasingly getting attention in academic circles and the public spheres, given the prevalence of urgent needs and challenges that society is facing on a global scale. The contemporary world is full of challenges or what some philosophers have called ‘existential risks’ to humanity. Nuclear wars, (...) natural and/or engineered pandemics, climate change, global totalitarianism, and emergent technologies, are some of the challenges mentioned by many authors devoted to the study of long-term potential risks for the survival of the human species. However, while there are many reasons to be a pessimist about the future of humanity, there is also a lot of ink wasted in showing that the world today is far better than we had in the past and also that there have been many instances of social and moral progress in the last centuries. Some authors have even claimed that “we have made more progress over the last 100 years than in the first 100,000”. According to ‘our world in data’, some of the most relevant advances of humanity in the last centuries have to do with the reduction of poverty and/or inequality, better health and security, the decline of violence and war, and the development of democracy and institutional mechanisms to guarantee individual freedom and rights. Yet, there is a more concrete concern that our world faces nowadays, and requires a particularly detailed analysis. In a few words, the advance in information and communication technologies, the huge volume of people migration because of prevalent instances of global inequality, and the reality of an interconnected world that just mirrors an extensive history of massive human intergroup relations open the question about the feasibility of social and moral progress in the contexts of diverse, multicultural, and unequal societies. This makes it crucial to reflect not only on whether human societies may keep advancing on a path of social progress, but how this can be achieved by addressing the challenges of inequality and potential intergroup conflict. This concern closely relates to the further consolidation of democratic values and the achievement of a more generalized consideration of the equal moral value of human individuals far from group, ethnic, or collective distinctions. This vision of progress follows the moral convictions that have been considered right and worthy to be pursued by most ethical theories explored by philosophers and social scientists so far. This work aims to contribute to the study of the mechanisms and feasibility of social and moral progress grounded on the precept of human equality and is guided by the idea that social and moral progress in a plural world requires the accomplishment of a more democratic and tolerant society. These forms of progress have already been defined by philosophers Allen Buchanan and Russel Powell as inclusivist forms of moral progress. According to these authors, inclusivist moral progress is featured by the transformation of moral judgments, motivations, and norms guided by the rejection of “group-based restrictions on moral standing and moral status” (2018). The work of Buchanan and Powell is fundamental for the argumentation developed in this work since they have pioneered a more complex debate in the field of evolutionary social sciences and philosophical anthropology. In brief, these authors have inquired how human nature, conceptualized by the advances in evolutionary thinking and the empirical sciences, is related to our moral convictions and the possibilities that we have to establish certain forms of social and moral progress. The work of Buchanan and Powell contributes to the debate on moral progress by incorporating empirically-informed concepts and arguments. With this objective in mind, they develop their discussion around a generalized tension between exclusivist and inclusivist forms of moral progress. This tension revolves around the question of whether and to what extent human moral concerns, motivations, and norms, are limited or bounded by social identities, group thinking, or collective values. This question is at the center of this work. In other words, I aim to answer whether and to what extent the nature of our social and moral cognition hinders or enables the development of inclusivist forms of morality and moral progress. As I mentioned so far, the distinction between exclusivist and inclusivist forms of morality has a practical implication and facilitates the reflection on the mechanisms and feasibility of concrete forms of progress based on the precept of human equality, which is the road to progress that we should follow according to most ethical theories. The distinction between exclusivist and inclusivist morality is not used here as a form of summarizing highly divergent descriptive approaches to morality, but as a way to address the practical implications of morality research, particularly around the question of the feasibility of social forms of progress based on the precept of equality and tolerance. My objective then has less to do with offering a conceptualization of human morality or with the proposition of a new ethical perspective. Instead, I aim to identify, from an empirically informed perspective, what enables the achievement of egalitarian forms of social progress, to subsequently offer a normative reflection about what we should do if we want to accomplish such inclusivist forms of progress. This task is of great relevance, having in mind that some theoretical proposals on the matter have claimed that human prosocial behavior and morality are constrained by exclusivist fixed tendencies as a product of our evolutionary history. According to these views, human morality is a group-centered cognitive and behavioral expression that has severe limits in its scope and extent, which hinders in the end the emergence of inclusivist forms of moral concerns and behaviors. These claims align with the philosophical intuition about the ‘dissociation of empathy’, or the fact that human individuals tend to express empathy and sympathy preferably for members of their group whereas their empathic and moral concern and recognition for outgroup individuals tend to be reduced or eliminated in real-life social interactions. Multiple theorists have expressed, however, that these assumptions are wrong for empirical and philosophical reasons, which results in a serious challenge to the conception of human morality as exclusivist by nature. Furthermore, simple intuition and practical experience constantly show us that human individuals can develop and endorse a broad spectrum of moral considerations and adopt an arguably inclusivist stance concerning the kind of persons or agents that deserve moral concern. Moreover, and adopting a historical perspective, the expansion of cultural and commercial exchanges, the consolidation of democracy, the development of welfare states, or the emergence of institutions based on the concept of universal human rights, have partially driven human progress based on the impartial concern for the well-being of persons. These historical instances of cultural evolution and institutional design have shown that it is feasible to promote behaviors and attitudes grounded in impersonal prosocial and inclusivist principles. This optimistic perspective, however, still begs the question of the exact relationship between social, cultural, and historical contexts, and the emergence of certain behavioral expressions of inclusivist morality. This is crucial since a great number of human individuals around the world still do not make part of these instances of social progress, and some authors have suggested that such instances of social and moral progress are particularly favored by the contexts of the WEIRD world, that is the world of Western, Educated, Industrialized, Rich, and Democratic societies. Some of these approaches consider moral inclusivity a ‘luxury good’ and follow the ‘dependency thesis’ according to which the expression of moral inclusivity depends on the presence of very concrete material conditions that trigger inclusivist and impersonal prosocial tendencies that human beings are not able to express in threatening contexts without physical security. This thesis is problematic for various reasons and has led to incomplete explanations about the enabling and causal factors of inclusivist moral progress, as well as unsatisfactory suggestions about what we should do to foster the accomplishment of more generalized instances of progress based on inclusivist concerns. In an attempt to contribute to this debate, the main objective of this thesis is to offer an alternative proposal about the nature of human morality and a more detailed reflection on what we should do if we want to further accomplish such instances of progress. More precisely, this work adopts a particular developmental and constructivist vision of human morality to answer the question of how feasible it is to reach generalized forms of social progress based on the precepts of moral inclusivity. Furthermore, it offers some ideas about what are the most adequate and favorable conditions to foster such progress both at the individual and the collective level. At this point, a preliminary clarification of some starting points is necessary. In the first place, and contrary to what other authors have proposed when debating moral progress from an empirically-based approach, my perspective adopts a radical developmental and constructivist perspective, following particularly the conceptual and empirical ideas of the social-domain theory in moral psychology. From this perspective, morality is a domain of normative and social knowledge that develops and emerges in human interactions. Moral concerns, judgments, and norms are not only the result of the expression of innate adaptive intuitions, nor the product of social conformity and a simple process of mirroring the normativity that communities have established to organize their social life. Human individuals, instead, construct moral concerns and judgments during their situated interactions. More specifically, the constructivist tradition claims that we need to research how moral concerns, judgments, and reasons emerge in social interactions and how human beings construct the content of their moral knowledge in the first place. Based on these ideas, morality is defined here as the result of a constructive process through which human individuals, by the means of constant interactions on a background of mutual respect and recognition, develop evaluative concerns about how we ought to treat others, and how to ‘care’ and ‘respect’ others’ well-being, needs, and vulnerabilities. This developmental-constructivist theory of human psychology contributes to an alternative understanding of the origins of moral variability and informs a very particular normative stance about the most desirable contexts needed for the urgent accomplishment of inclusivist forms of morality in contemporary societies. This is so given that the very same definition of morality adopted presupposes the feature of inclusivity. The main objective of this work is then to argue, based on a developmental perspective, what are the most favorable conditions to foster the development of moral inclusivity and what we should do to accomplish concrete instances of moral progress that truly help us to overcome our most urgent moral challenges. The whole thesis is organized as follows. In part I, I show how received visions about human social evolution have informed conceptions of morality as an adaptive function evolved to solve the challenges of cooperative life. Based on these assumptions, some theories argue that human morality is limited by the boundaries of group thinking, and always obeys the mandates of collective interests and the will of the majority. However, this conception has problematic implications from a normative and ethical perspective. The aim of Chapter 1 is to present this introductory debate in detail. In chapter 2, I consider a relevant amount of scientific evidence that helps to consolidate a more optimistic and inclusivist perspective about the starting conditions of human prosocial behavior. Later, I will summarize some ideas offered to explain the possible evolutionary mechanisms that led to the consolidation of these inclusivist capacities. However, I will also show how evolutionary theories that share the same adaptationist foundations but initially seem relevant to explain the feasibility of moral inclusivity, result incomplete when considering the complexity of moral behavior and its ethical implications. Part II is devoted to presenting a developmental alternative to the adaptationist versions around the starting conditions of morality. In this section, I first summarize the epistemological, conceptual, and empirical basis of a constructivist perspective already proposed by several authors in the last decades. This is the goal of chapter 3. More precisely, I adopt the conceptualization of morality established by the social-domain theory school and clarify its conception of the situated development of moral concerns, motivations, and norms. All these ideas are essential for my argumentation on the feasibility of inclusivist moral progress offered later. Chapter 4 provides a more detailed idea of constructivist thinking about moral development, by analyzing one particular dimension: the development of moral concerns for fairness and the sense of justice in distributive dilemmas. In Part III, I assume a constructivist perspective on morality to contribute to the philosophy of moral progress. In particular, I discuss the implications of such a perspective for the conceptualization of human moral nature and discuss what are the most favorable conditions for moral inclusivity to emerge. Answering that question is of enormous relevance since favoring the transition of human societies towards more inclusivist forms of moral concern and behavior supposes a more generalized accomplishment of our most urgent moral convictions. Previous developmental or culturally-sensible attempts to explore this issue are already on the market. As mentioned before, most authors have approached the topic by situating the cultural evolution and development of (inclusivist) moral progress in the WEIRD world. For instance, some of these authors claim that very concrete material conditions (mostly present in the Western World) have been necessary for triggering inclusivist and impersonal prosocial tendencies that human beings are not able to express in threatening contexts without physical security. Despite their interest in explaining inclusivist morality and the feasibility of inclusivist forms of progress following a naturalistic and culturally situated approach, these theories are problematic for two main reasons. In the first place, most of the authors that explain moral progress tend to focus exclusively on the consolidation of liberal values in the Western world and the underlying adoption of laws, social-epistemic practices, and public narratives about tolerance and inclusivity, as unequivocal signs of inclusivist morality. Nevertheless, there is an enormous distance between the institutional and public support of inclusivist moral values or the construction of public images of tolerance and inclusivity, and the real materialization of impersonal moralities in situated social interactions. Secondly, the variability of human moral behavior is far bigger than most of the theories in moral psychology and moral progress tend to assume. Accordingly, inclusivist and exclusivist forms of morality may develop simultaneously in similar or divergent geographical and socio-ecological environments, including those with harsh conditions such as competition for scarce resources, potential intergroup conflict, and risks of disease transmission. In addition, harsh environmental conditions are usually present in almost all societies around the globe, and the presence of socio-ecological conditions such as physical security and prosperity, predominant in highly resourced populations, do not prevent the existence of exclusivist moral tendencies. My model explores a different perspective on the relationships between cultural, institutional, and historical factors, and the situated development of human morality. This supposes a clear distinction from previous approaches to the matter since it offers a different view on what we should do to pursue further instances of inclusivist social progress. In the fifth chapter, I first analyze the proposals of some defenders of the ‘dependency’ theory. The attention is focused on the ‘Evolutionary Developmental Model’ proposed by Buchanan and Powell (2018). Based on a critique of this approach, I will argue that to explain the evolution and development of human morality in its multiple manifestations, it is essential to put focus on social interactions. This also involves a different perspective on human-environment relations that in line with a constructivist worldview makes an innovative contribution to the philosophy of moral behavior and moral progress. Later, in the sixth chapter, I will define my alternative relational view of inclusivist morality and I will offer my view on how to establish favorable conditions that make inclusivist morality possible. Complementing the constructivist approach, my conception is based on the essential role of equality and individuality and on how moral inclusivity is favored if moral concerns do not develop driven by the accomplishment of group-centered, binding, and communitarian concerns and values. In brief, my relational model suggests that the accomplishment of moral inclusivity not only depends on the overall achievement of certain levels of physical security or economic prosperity. Instead, its development is favored by transforming the interactional contexts in which moral concerns towards autonomy and individuality emerge. In arguing so, I will need to start with a critique of contemporary situated and embodied approaches in ethics. Then, I will show how societies guided by the accomplishment of group-centered values of power, dominance, and relational inequality tend to express exclusivist moral behaviors, while individualistic societies tend to be more inclusivist. Starting from this diagnosis, my final attempt is then to reflect on which are the best conditions for the moral valuation of individuality to emerge and what we should do to promote the accomplishment of moral inclusivity at the societal level.

El filósofo mexicano Emilio Uranga (1921-1988) es recordado por su Análisis del ser del mexicano (1952) y por su labor como periodista político y asesor de López Mateos, Díaz Ordaz, Echeverría y López Portillo. Es posible tender un puente entre los dos aspectos, gracias a su concepción ontologizante de la Revolución Mexicana, leitmotiv de su producción teórica.

El presente artículo recuerda momentos cruciales de una historia del sujeto que va de Jacques Lacan a Alain Badiou. Tras la división y la subversión lacaniana del sujeto, se revisan reacciones que intentan revertirla en varios autores. Estas reacciones se contrastan con la idea badiouana de la escisión del sujeto entre el esplacio y el fuera-de-lugar. La absolutización estructuralista del esplacio estructural se ilustra con la acción de la estructura de Jacques-Alain Miller, se aproxima al argumento de las estructuras que (...) descienden a la calle con el que Lacan defendió la posición estructuralista contra Lucien Goldmann y se explica por la forclusión del sujeto en el estructuralismo, en el sistema capitalista y en la ciencia en general. Con respecto al campo científico, se muestra cómo fue definido primero por la forclusión y luego por la suturación del sujeto en Miller, simultáneamente por la forclusión y la suturación en Lacan, y sólo por la forclusión en Badiou, quien empezará negando y terminará aceptando la existencia de un sujeto de la ciencia, pero diferente del de Lacan y Miller.

Substantial advances in our understanding of the neural bases of emotional processing have been made over the past decades. Overall, studies in humans and other animals highlight the key role of the amygdala in the detection and evaluation of stimuli with affective value. Nonetheless, contradictory findings have been reported, especially in terms of the exact role of this structure in the processing of different emotions, giving rise to different neural models of emotion. For instance, although the amygdala has traditionally been (...) considered as exclusively involved in fear (and possibly anger), more recent work suggests that it may be important for processing other types of emotions, and even nonemotional information. A review of the main findings in this field is presented here, together with some of the hypotheses that have been put forward to interpret this literature and explain its inconsistencies. (shrink)

The issue of time appears in the analysis that the Bishop of Hippo makes of the account of creation in Genesis, and offers better understanding the nature of created things and with them, created time. The way Augustine understands reality allows us to understand his interpretation of Genesis, which enriches the treatise’s view of time in Book XI of Confessiones, since in De Genesi ad litteram and De civitate Dei Augustine addresses time, not as experiences the soul, but as a (...) creature made with other creatures, and linked to change and movement. (shrink)

The issue of time within Augustine’s work requires a new look, as the problem has been seen in an almost generalized way from the perspective of Book XI of Confessions, and sufficient prominence has not been given to his reflection before this great work. The central text on time has received excessive interpretation, leaving in the background previous approaches, such as in De Musica, Book VI, where the saint addresses the issue of time in the middle of his analysis of (...) temporal and eternal rhythms.

In the Augustinian reflection on time, the analysis derives from its condition as a creature; for this reason, the time turns out to be as it is, that is, turns out to have this ontological precariousness that shares with all creation. When we asked about the time, we discover that this reality is not something that our understanding can address as when a man takes an unknown object, but this notion is revealed to us as a dimension of our being. (...) In this article, I propose an interpretation key of the Book XI of Confessions in which I show the importance of presenting the sense of temporal existence facing the eternal Creator and also I propose an interpretation of the dual dimension, positive and negative, of distentio animi.

Moving into the space of tension and contradiction between philosophy and psychoanalysis, I reflect on the spectral way in which Marx and his legacy appear in the Lacanian Left. I explain this spectrality through the impossible mourning of Marxism. I bring in three authors who prescribe mourning here and ignore its impossibility: Özselçuk, Stavrakakis and Alemán. I resort to Benjamin, Lacan, Allouch and Traverso to problematise the Freudian distinction between mourning and melancholy in its application to Marxism. Instead of mourning (...) with its post-Marxist bet, I defend an openly melancholic position based on the militant historical commitment to the dead and what Lacan has represented as the insurmountable directions indicated by Marx. I distinguish three great idealist attempts by the Lacanian Left to overcome the materially insurmountable directions: Laclau’s anti-essentialist discursive postmodernism, Žižek’s pessimistic Lacanian Hegelianism and Badiou’s Jacobin political Platonism. I contrast the Laclauian democratic populist concessions with the Badiouan-Žižekian fidelity to Marxism and communism. (shrink)

Research on Augmented Reality in education has demonstrated that AR applications designed with diverse components boost student motivation in educational settings. However, most of the research conducted to date, does not define exactly what those components are and how these components positively affect student motivation. This study, therefore, attempts to identify some of the components that positively affect student motivation in mobile AR learning experiences to contribute to the design and development of motivational AR learning experiences for the Vocational Education (...) and Training level of education. To identify these components, a research model constructed from the literature was empirically validated with data obtained from two sources: 35 students from four VET institutes interacting with an AR application for learning for a period of 20 days, and a self-report measure obtained from the Instructional Materials Motivation Survey. We found that the following variables: use of scaffolding, real-time feedback, degree of success, time on-task and learning outcomes are positively correlated with the four dimensions of the ARCS model of motivation: Attention, Relevance, Confidence, and Satisfaction. Implications of these results are also described. (shrink)

Todo ahora es diferente, la vida ha cambiado de manera inminente y casi sin que nos demos cuenta de ello. Se ha dejado de lado la importancia de tantas cosas, al parecer vivimos en una clase de “modo automático”, ya no surgen preguntas filosóficas, ya no hay interés en el porqué de las cosas, no hay curiosidad dentro de nosotros; ¿Qué está pasándole a la sociedad?, acaso es que hemos perdido una parte de ser humano que jamás volverá, la sensibilidad, (...) el deseo de vivir, la felicidad, la importancia del cuerpo, del arte, la cultura, el amor, el conocimiento, la vocación, ¿todo esto ya ha sido reemplazado? creemos que sí.Avanzamos a zancadas enormes, la vida está corriendo muy aprisa, la ciencia y la tecnología parecen encerrarnos en una burbuja invisible, de la cual es imposible escapar, todos y cada uno de nosotros estamos dentro de ella.Las nuevas tecnologías nos han transformado en lo que Guy Deboard llama ‘La sociedad del espectáculo’ y que más adelante Mario Vargas Llosa vuelve a retomar en ‘la civilización del espectáculo’; las redes sociales han generado en nosotros actitudes de desinterés, pérdida de identidad, nos hemos convertido, claramente, en una sociedad en la que se premia a los mejores civiles en base al éxito que tienen en sus redes, la influencia que tienen ante los demás; hemos perdido la importancia de la intelectualidad, los saberes contenidos en nosotros, ya no almacenamos nada, todo se ha vuelto desechable, y tal parece que vivimos en una sociedad desechable también, que no se preocupa por valorar, cuidar, recompensar las buena acciones; se premia a un futbolista de la misma manera que se premia a un intelectual del premio nobel, y esto claramente es indignante. En el presente trabajo pretendemos dar a conocer, ampliar y relacionar la ‘civilización’ del espectáculo y la ‘sociedad’ del espectáculo en las redes sociales, y cómo esto, sin duda, genera en nosotros conflictos, tanto individuales como colectivos.

Contemporary philosophy, having grown inside the cultural background of modem times, also cherishes in a clearer, although less attractive way, the germine metaphysical enterprise which proceeds from the philosophia prima. This sort of philosophy deserves to be called not only post-modern, but supra-modern, classical.

This Article considers the conditions under which administrative agencies - particularly those with public health-related missions - may obtain partial autonomy from external interests or politicians. In the process, it critiques the proposition that administrative agencies in advanced industrialized countries such as the United States are routinely “captured” by external economic interests. Through case studies and the application of relevant theory from law and the study of political organization, the Article describes how agencies can produce a measure of autonomy by (...) forging coalitions of stakeholders both internal and external to the agency, and considers how partial autonomy may be modeled as a strategic process involving decisions under uncertainty. The Article then investigates how American publichealth agencies such as the Food and Drug Administration, the Food Safety Inspection Service, and the Centers for Disease Control have been able to use their partial autonomy to develop significant health policy innovations. Although agencies are by no means guaranteed even a partial degree of autonomy, they are nonetheless capable of affecting their political and legal environment, with consequences not only for public-health policy but also for the legitimacy of the nation-state.

El presente artículo se ocupa de la orientación marxista del filósofo esloveno Slavoj Žižek. Se intenta elucidar su lectura de Marx, su relación con él y su particular versión del marxismo. Primero se indaga cómo Žižek adopta ciertas concepciones marxianas de la universalidad, la retroactividad, la contingencia, el materialismo, la libertad y la economía. Luego se examina la forma en que, por un lado, Žižek aplica ciertas ideas de Marx a la explicación del mundo actual y, por otro lado, reinterpreta (...) el pensamiento marxiano desde una perspectiva lacaniana u original, propiamente žižekiana. Por último, después de haberse detectado algunos puntos en los que Žižek adhiere a Marx, se abordan críticamente otros puntos en los que discrepa de él. (shrink)

Resumen A diferencia de trabajos anteriores sobre el universalismo y el colonialismo en el pensamiento filosófico y político de Žižek, el presente artículo se basa en profundas coincidencias con este pensamiento, así como en irreductibles discrepancias con respecto a muchos de sus detractores. Todo esto no impide que se disienta con respecto a dos puntos fundamentales del filósofo esloveno: su posición universalista abiertamente eurocéntrica y su concepción positiva del colonialismo. La doble divergencia es resumida y justificada en las siguientes doce (...) tesis y en las objeciones que plantean a lo que se juzga inaceptable en el pensamiento žižekiano: 1) la conciencia y la crítica del horror colonial no son legados europeos; 2) el colonialismo es él mismo opresión; 3) hay otros orígenes fuera de Europa; 4) nunca se pierden todas las raíces; 5) lo aparente puede ser lo universal; 6) el capitalismo nunca supera su particularidad; 7) el capitalismo sigue comportando la colonialidad; 8) la modernidad capitalista incluye una otredad que no es ni anterior ni posterior; 9) la otredad sabe cómo explotar lo europeo que la explota; 10) un sujeto puede encontrarse en más de un universo; 11) no todo es comparable al ello fuera de Europa y Estados Unidos; y 12) es Europa la que se distorsiona al reflejarse en Estados Unidos.Unlike earlier work on universalism and colonialism in Žižek’s philosophical and political thought, this article draws on deep coincidences with this thought, as well as irreducible disagreements with many of its detractors. All this does not prevent that there are also divergences with respect to the two fundamental points of the Slovenian philosopher: his universalist openly Eurocentric position and his positive conception of colonialism. The double divergence is summarized and justified in the following twelve theses and in the objections they raise to what is deemed unacceptable in Žižekian thought: 1) the consciousness and critique of colonial horror are not European legacies; 2) colonialism is itself oppression; 3) there are other origins outside of Europe; 4) all roots are never lost; 5) the apparent can be the universal; 6) capitalism never overcomes its particularity; 7) capitalism continues to involve coloniality; 8) capitalist modernity includes an otherness that is neither anterior nor posterior; 9) otherness knows how to exploit the European that exploits it; 10) a subject can be found in more than one universe; 11) not everything is comparable to the id outside of Europe and the United States; and 12) it is Europe that is distorted when reflected in the United States.

When a circular coin is rotated in depth, is there any sense in which it comes to resemble an ellipse? While this question is at the center of a rich and divided philosophical tradition (with some scholars answering affirmatively and some negatively), Morales et al. (2020, 2021) took an empirical approach, reporting 10 experiments whose results favor such perspectival similarity. Recently, Burge and Burge (2022) offered a vigorous critique of this work, objecting to its approach and conclusions on both philosophical (...) and empirical grounds. Here, we answer these objections on both fronts. We show that Burge and Burge’s critique rests on misunderstandings of Morales et al.’s claims; of the relation between the data and conclusions; and of the philosophical context in which the work appears. Specifically, Burge and Burge attribute to us a much stronger (and stranger) view than we hold, involving the introduction of “a new entity” located “in some intermediate position(s) between the distal shape and the retinal image.” We do not hold this view. Indeed, once properly understood, most of Burge and Burge’s objections favor Morales et al.’s claims rather than oppose them. Finally, we discuss several questions that remain unanswered, and reflect on a productive path forward on these issues of foundational scientific and philosophical interest. (shrink)

Whether the prefrontal cortex is part of the neural substrates of consciousness is currently debated. Against prefrontal theories of consciousness, many have argued that neural activity in the prefrontal cortex does not correlate with consciousness but with subjective reports. We defend prefrontal theories of consciousness against this argument. We surmise that the requirement for reports is not a satisfying explanation of the difference in neural activity between conscious and unconscious trials, and that prefrontal theories of consciousness come out of this (...) debate unscathed.

Este artículo analiza una fotografía de Fidel Castro que es muy lejana a la etapa épica del guerrillero, pero que forma parte de la iconografía en torno a este personaje. Se trata de un retrato de Fidel a los tres años, tomado en Birán, en 1929, estudiado con el objeto de comprender los intereses y las inten ciones alrededor de su producción, así como los usos actuales de esa misma imagen. Partiendo de la consideración de la fotografía como una práctica (...) social y cultural que integra significados, ella debe ser incorporada en el estudio de la historia como un documento que permite aportar información de sus contextos de producción y reproducción. A partir de estas consideraciones, se pudo observar el significado de la representación iconográfica de Fidel a los tres años, quien fue fotografiado utilizando convenciones que resaltaban las favorables condiciones económicas de las que gozaba la familia Castro Ruz, sin embargo, la investigación revela que se le han añadido significados en sus posteriores usos, producto de intereses políticos en torno a la trayectoria guerrillera de Fidel.

América Latina es un concepto, una construcción intelectual que intenta dar cuenta de un grupo de estados nacionales, variable en su composición pero con un núcleo estable, las ex colonias españolas y portuguesas del continente americano. Hoy no hay en América Latina un programa de desarrollo nacional alternativo a la integración al mundo capitalista global. Las experiencias nacionales que la izquierda dirige no constituyen una imagen como la que representó Cuba en los años sesenta, ni desde el punto de vista (...) de los programas ni desde el liderazgo. Lo que se construyó en las décadas de los cincuentas y sesentas fue una conciencia de la relevancia de un proyecto continental que merecía ser respaldado por una teorización del conjunto, la construcción de un objeto de conocimiento al mismo tiempo que un actor político colectivo. Como quiera que sea, esta conciencia se desarrolló alrededor de las instituciones internacionales y nacionales residentes en Santiago de Chile y comenzó a desvanecerse junto con el proyecto de Allende y la Unidad Popular.

Las primeras imágenes cinematográficas rodadas por los estadounidenses en Cuba se remontan a la Guerra Hispano cubana norteamericana, anterior al surgimiento de Hollywood y su consolidación como industria del espectáculo. Los filmes producidos en esta etapa constituyen el preámbulo del denominado cine de propaganda política que, según el historiador Román Gubern, ha llegado hasta la actualidad y, sobre todo, develan el carácter manipulador que desde sus inicios ha tenido el lenguaje cinematográfico. Entre las décadas del `30 y `40 los filmes (...) realizados por Hollywood en la isla han proyectado una imagen exótica y estereotipada sobre la identidad cubana. No solo se ha desvirtuado nuestra memoria histórica, sino también nuestros valores identitarios, imagen que se ha extendido hasta el contexto actual.En la extensa historia del cine hollywoodense no son pocas las cintas que han abordado aspectos de nuestra historia. Independientemente de la calidad de la gran mayoría de estos filmes, no se puede minimizar su importancia en el obsesivo intento por construir una imagen creíble y veraz sobre Cuba. Aunque la gran mayoría de las cintas realizadas por cineastas estadounidenses sobre la isla se encuentran limitadas por el hecho de haberse rodado en espacios y locaciones de otras naciones con semejanzas geográficas y culturales con Cuba, dicha limitación no es sinónimo de pobreza artística. El objetivo fundamental de este ensayo radica en el análisis de la representación de la imagen e identidad de Cuba en la industria de Hollywood, a partir del estallido de la Guerra Hispano-cubana-norteamericana el 15 de febrero de 1898 hasta la administración del presidente Barack Obama, período histórico conocido como el Deshielo, porque ambas naciones decidieron restablecer relaciones diplomáticas interrumpidas en plena Guerra Fría, específicamente en 1961.

Metaphysics as the foundation of science, philosophy as an exact method to discover this foundation: These are central themes in the Kant-Friesian philosophy which, at the beginning of the 20th century, Leonard Nelson, using the methods of mathematical axiomatics, further developed into interdisciplinary research programmes. Nelson carried out this research programme in his ethics but his untimely death prevented a systematic presentation of his natural philosophy and his doctrine of method. The present volume contains four transcripts of his seminars on (...) natural philosophy which he held over a period of 15 years. The transcripts, which may be taken as a comparatively complete presentation of Nelson's natural philosophy, supplement the writings published during his lifetime and convey a representative picture of his natural philosophy. // Metaphysik als Fundament der Wissenschaften, Philosophie, eine exakte Disziplin, die dieses Fundament offenlegt: Leitmotive des Kant-Fries’schen Denkgebäudes, die Leonard Nelson zu Beginn des 20. Jahrhunderts in interdisziplinäre Forschungsprogramme umsetzt. Die dabei angewandten – an der mathematischen Axiomatik ausgerichteten – Methoden haben nichts an Aktualität eingebüßt. Kann Nelson dieses Vorhaben bezüglich seiner Ethik verwirklichen, so verhindert sein früher Tod eine systematische Darstellung seiner Naturphilosophie und Methodenlehre. Der vorliegende Band enthält vier Mitschriften von Lehrveranstaltungen Nelsons. Diese Schriften, die die zu seinen Lebzeiten veröffentlichten Arbeiten zur Naturphilosophie ergänzen und erweitern sollen, decken einen Zeitraum von ca. 15 Jahren ab und geben somit einen repräsentativen Einblick in Nelsons naturphilosophisches Schaffen. Die vorliegende Zusammenstellung naturphilosophischer Nachlassschriften darf als verhältnismäßig vollständig gelten. (shrink)
