La erosión de la confianza en las capacidades epistémicas de la ciudadanía tiene en su raíz la radical separación entre hechos y valores que el pragmatismo ha considerado como clave de nuestra cultura. Hoy es posible superar el dualismo sobre la base de un conjunto de virtudes y disposiciones individuales que son tanto éticas como epistémicas. Este entrelazamiento entre lo ético y lo epistémico pone de manifiesto la imbricación entre una concepción deliberativa de la democracia con su exigencia de una (...) ética cívica y los requerimientos de una ética de la investigación científica en el marco de una sociedad democrática.

Partiendo de los análisis de los epistemólogos de la virtud que sitúan la mentalidad abierta como virtud epistémica central el artículo muestra el indisoluble entrelazamiento entre sus dimensiones éticas y epistémicas. Se entiende la mentalidad abierta como virtud de acuerdo con una concepción falibilista de la experiencia y el conocimiento humano en el que se acentúa la capacidad de intervención del agente a través de sus disposiciones y hábitos. Finalmente, la argumentación conduce a una defensa ética del liberalismo político.

Este trabajo interpreta el auge de los códigos éticos y de la ética profesional desde el punto de vista de su contribución a la formación de una ciudadanía democrática. Se analizan diversos aspectos de la ética profesional desde la perspectiva de una ética del agente para la que bienes, normas y virtudes resultan factores complementarios para el cultivo de la inteligencia y el juicio individual. A través de una concepción de la democracia que la vincula con los hábitos y modos (...) de vida, la ética profesional adquiere una renovada significación como elemento central para la autorrealización personal y la emancipación social. En definitiva, bajo el rótulo del profesionalismo democrático, y de la mano de la filosofía moral y política de Dewey, se muestra que la ética profesional es más que un campo de aplicación, un elemento constituyente de una ética cívica en el marco de una sociedad democrática.

The paper understands the rise of ethical codes and professional ethics from the point of view of their contribution to the formation of a democratic citizenship. Various aspects of professional ethics are analyzed from the perspective of an agent-based ethics for which goods, norms and virtues are complementary factors for intelligence and individual judgment development. Through a conception of democracy understood as a way of life, professional ethics acquire a renewed meaning as a central element for individual self-realization and social (...) emancipation. In short, under the label of democratic professionalism, and following Dewey’s moral and political philosophy, it is shown that professional ethics are more than a field of application, a constituent element of a civic ethic within the framework of a democratic society.

Moral Perfectionism: Ethical Theory from a Pragmatic Approach This article tries to rescue the perfectionist approach to moral theory from the pragmatic tradition and inspiration. Based on the philosophy of Dewey and taking into account authors like H. Putnam or S. Cavell, it tries to defend the idea that pragmatism allows us to understand moral perfectionism in a new way. In that way, perfectionism is bound to a certain interpretation of practical rationality, and a new understanding of moral objectivity and (...) human subjectivity. Finally, moral perfectionism is not a theory that aims to solve all moral dilemmas but provides an understanding of how to face up to the problems of ordinary moral life. (shrink)

RESUMEN El artículo responde algunas críticas planteadas por Ignacio Ávila a mi interpretación de la epistemología davidsoniana. Presento argumentos en contra de: a) que sea necesario distinguir entre representaciones epistemológicamente “peligrosas”e “inofensivas”; b) que el empirismo mínimo sea un tipo de realismo directo; c) que mi uso de la expresión “evidencia distal” y el interés por la teoría de la correspondencia sean asuntos ajenos a Davidson. Finalmente, sostengo que la triangulación es un elemento fundamental de la epistemología davidsoniana, pues permite (...) sortear la ansiedad realista manteniéndose en una postura no representacionalista. ABSTRACT In this article, I respond to some of Ignacio Ávila's criticisms of my interpretation of Davidson’s epistemology. I argue against: a) the need to distinguish between epistemologically “dangerous” and “harmless” representations; b) the idea that minimal empiricism is a kind of direct realism; and c) the claim that my usage of the expression “distal evidence” and interest in the theory of correspondence are issues that do not pertain to Davidson. Finally, I claim that triangulation is a key element in Davidsonian epistemology since it allows us to deal with the realist anxiety while maintaining a non-representationalist viewpoint. (shrink)

The literature addressing bias and fairness in AI models (fair-AI) is growing at a fast pace, making it difficult for novel researchers and practitioners to have a bird’s-eye view picture of the field. In particular, many policy initiatives, standards, and best practices in fair-AI have been proposed for setting principles, procedures, and knowledge bases to guide and operationalize the management of bias and fairness. The first objective of this paper is to concisely survey the state-of-the-art of fair-AI methods and resources, (...) and the main policies on bias in AI, with the aim of providing such a bird’s-eye guidance for both researchers and practitioners. The second objective of the paper is to contribute to the policy advice and best practices state-of-the-art by leveraging from the results of the NoBIAS research project. We present and discuss a few relevant topics organized around the NoBIAS architecture, which is made up of a Legal Layer, focusing on the European Union context, and a Bias Management Layer, focusing on understanding, mitigating, and accounting for bias.

Investigates the resolution of contradictions and ambiguous derogations in a code, by means of the imposition of partial orderings.

This article reports the findings of a survey examining if there are gender and career stage differences between male and female practitioners regarding ethical judgment. The results show that, on average, females adopted a more strict ethical stance than their male counterparts on 7 out of 19 vignettes. Males on the other hand, demonstrated a more ethical stance than their female counterparts on 2 out of 19 vignettes. The results furthermore indicate there is a significant difference in ethical judgment across (...) career stages. Overall, it appears that practitioners in later career stages display higher ethical judgment than practitoners in lower career stages. Implications are provided for both practitioners and academicians. (shrink)

This paper explores aspects of GPT-3 that have been discussed as harbingers of artificial general intelligence and, in particular, linguistic intelligence. After introducing key features of GPT-3 and assessing its performance in the light of the conversational standards set by Alan Turing in his seminal paper from 1950, the paper elucidates the difference between clever automation and genuine linguistic intelligence. A central theme of this discussion on genuine conversational intelligence is that members of a linguistic community never merely respond “algorithmically” (...) to queries through a selective kind of pattern recognition, because they must also jointly attend and act with other speakers in order to count as genuinely intelligent and trustworthy. This presents a challenge for systems like GPT-3, because representing the world in a way that makes conversational common ground salient is an essentially collective task that we can only achieve jointly with other speakers. Thus, the main difficulty for any artificially intelligent model of conversation is to account for the communicational intentions and motivations of a speaker through joint attention. These joint motivations and intentions seem to be completely absent from the standard way in which systems like GPT-3 and other artificial intelligent systems work. This is not merely a theoretical issue. Since GPT-3 and future iterations of similar systems will likely be available for commercial use through application programming interfaces, caution is needed regarding the risks created by these systems, which pass for “intelligent” but have no genuine communicational intentions, and can thereby produce fake and unreliable linguistic exchanges.

What are the limits of the use of artificial intelligence (AI) in the relational aspects of medical and nursing care? There has been a lot of recent work and applications showing the promise and efficiency of AI in clinical medicine, both at the research and treatment levels. Many of the obstacles discussed in the literature are technical in character, regarding how to improve and optimize current practices in clinical medicine and also how to develop better data bases for optimal parameter (...) adjustments and predictive algorithms. This paper argues that there are also in principle obstacles to the application of AI in clinical medicine and care where empathy is important, and that these problems cannot be solved with any of the technical and theoretical approaches that shape the current application of AI in specific areas of clinical medicine in which care for patients is fundamental. This is important, because it generates specific risks that may be overlooked otherwise, and it justifies the necessity of human monitoring and emotional intervention in clinical medicine. Consequently, difficult issues concerning moral and legal responsibility may ensue if these in principle problems are ignored. (shrink)

Recent work in the philosophy of biology has attempted to clarify and defend the use of the biodiversity concept in conservation science. I argue against these views, and give reasons to think that the biodiversity concept is a poor fit for the role we want it to play in conservation biology on both empirical and conceptual grounds. Against pluralists, who hold that biodiversity consists of distinct but correlated properties of natural systems, I argue that the supposed correlations between these properties (...) are not tight enough to warrant treating and measuring them as a bundle. I additionally argue that deflationary theories of biodiversity don’t go far enough, since a large proportion of what we value in the environment falls outside bounds of what could reasonably be called “diversity”. I suggest that in current scientific practice biodiversity is generally an unnecessary placeholder for biological value of all sorts, and that we are better off eliminating it from conservation biology, or at least drastically reducing its role.

The Polish logician Roman Suszko has extensively pleaded in the 1970s for a restatement of the notion of many-valuedness. According to him, as he would often repeat, “there are but two logical values, true and false.” As a matter of fact, a result by W´ojcicki-Lindenbaum shows that any tarskian logic has a many-valued semantics, and results by Suszko-da Costa-Scott show that any many-valued semantics can be reduced to a two-valued one. So, why should one even consider using logics with more (...) than two values? Because, we argue, one has to decide how to deal with bivalence and settle down the tradeoff between logical 2-valuedness and truth-functionality, from a pragmatical standpoint. -/- This paper will illustrate the ups and downs of a two-valued reduction of logic. Suszko’s reductive result is quite non-constructive.We will exhibit here a way of effectively constructing the two-valued semantics of any logic that has a truth-functional finite-valued semantics and a sufficiently expressive language. From there, as we will indicate, one can easily go on to provide those logics with adequate canonical systems of sequents or tableaux. The algorithmic methods developed here can be generalized so as to apply to many non-finitely valued logics as well —or at least to those that admit of computable quasi tabular two-valued semantics, the so-called dyadic semantics.

This article presents what I call the Central Normative Proposal of Luis Villoro. This proposal is based on an interpretation of the principle of non-exclusion in ethics and epistemology. The core argument of the paper is based on a linguistic analogy that demonstrates the importance of reasonable communication for non-exclusion in epistemology, which is assumed in various theses of Villoro. A consequence of this analogy for non-exclusion in ethics is that Villoro defends basing what is reasonable on the concrete possibilities (...) of mutual understanding, starting with asymmetries and injustices that are obfuscated or eliminated in a contractualist analysis, or one that begins with strictly egalitarian principles. This criticism is compatible with egalitarian views, but it assumes a radically different point of departure. Although various theses by Villoro are compatible with egalitarian notions, given this point of departure based on asymmetries of power his proposal should be understood based on our cognitive capacities to understand and appreciate such asymmetries. For this reason, the paper concludes with an analysis of the notion of reasonableness, which under my interpretation Villoro defines in terms of our capacities for attention, that are not reducible to beliefs or systems of beliefs. In this way, the Central Normative Proposal of Villoro depends on the convergence between truth and the dignity of the members of communities in which as matter-of-fact asymmetries exist and must be eliminated through concrete communicative efforts.

The present text surveys and reevaluates the meaning and scope of Ortega y Gasset’s philosophy. The chapters reveal the most important aspects of his history such as the Neokantian training he went thru in Germany as well as his discovery of Husserl’s phenomenology around 1912. The work also covers his original contributions to philosophy namely vital and historical reason - and the cultural and educational mission he proposed to achieve. The Spanish – and to a certain extent the European – (...) circumstance was the milieu from which his work emerged but this does not limit Ortega’s scope. Rather, he believed that universal truths can only emerge from the particulars in which they are embedded. The publication in 2010 of a critical edition of his Complete Works opened worldwide access for many unpublished manuscripts, and some of his lectures. There is renewed interest among students and researchers in Ortega and this book uniquely delivers scholarship on his content in English. (shrink)

Freire is one of the most powerful voices challenging the hegemony of bureaucratic and banking educational systems. His voice was particularly influential impacting revolutionary processes and progressive social movements while at the same time learning from their practices. However, some silences in his oeuvres requires further examination. In this article, we focus on the silences of Freire regarding education and its relationship with work and labor, gender issues, and citizenship building.

This commentary focuses on the importance of attention skills in the development of universal associative learning, and it explains why the centrality of attention in UAL presents a considerable difficulty for the UAL approach. Attentional abilities are not just developmentally related to UAL but are in fact explanatory of UAL. The main problem is that all the types of attention involved in UAL can be dissociated from consciousness. This means that while attention skills for UAL might be necessary for consciousness, (...) they are not sufficient because they can all occur unconsciously. Thus, the possibility that UAL capacities might not be sufficient for consciousness cannot be eliminated, thereby challenging the key claim of the UAL approach. (shrink)

Mineral species are, at first glance, an excellent candidate for an ideal set of natural kinds somewhere beyond the periodic table. Mineralogists have a detailed set of rules and formal procedure for ratifying new species, and minerals are a less messy subject matter than biological species, psychological disorders, or even chemicals more broadly—all areas of taxonomy where the status of species as natural kinds has been disputed. After explaining how philosophers have tended to get mineralogy wrong in discussions of natural (...) kinds, I show how minerals species don’t behave like natural kinds. They are defined on the basis of human intentionality, not merely natural distinctions. They aren’t ideal grounds for inductive inference. And they don’t form a system that divides nature along a set of equivalent joints. While this is a regrettable outcome to those of us who like the idea of science relying on natural kinds, I contend that mineralogy is doing just fine without a natural kind-based taxonomy, and may in fact be better off without one.

The objective of the present review on the evolution of Green Chemistry, since its emergence until 2016, aimed an integrated vision of its progress along the three phases of its development: emergence, divulgation and consolidation. The methodology involved the analysis of a selection of bibliography on the evolution of GC collected from issues of the ACS symposia series; editorials in specialized GC journals; and commemorative birthday papers/editorials of these journals and of the GC itself. The analysis allowed to identify and (...) discuss the characteristics and conceptions of GC agents about fundamental concepts and procedures, in order to visualize and better understand the state of knowledge and the subject areas that make up the field. The main alterations identified in the evolution of GC were: it acquired a better defined identity, with more participation of academy and increased scope; was progressively framed in sustainability; has been aspiring to a holistic frame and to a change on the nature of the innovation for its implementation, from incremental to transformative. The analysis suggests that for supporting expansion and consolidation of GC the following aspects deserve attention: full validation of chemical greenness by metrics; better characterization of the frontiers of GC research areas/themes; increased integration between academy and industry; and penetration in chemistry curricula. Its basic philosophy being the practice of a chemistry more focused on the environment preservation, GC means a new stage in nature and in the history of Chemistry. (shrink)

Supposedly, stubbornness on the part of scientists—an unwillingness to change one’s position on a scientific issue even in the face of countervailing evidence—helps efficiently divide scientific labor. Maintaining disagreement is important because it keeps scientists pursuing a diversity of leads rather than all working on the most promising, and stubbornness helps preserve this disagreement. Planck’s observation that “Science progresses one funeral at a time” might therefore be an insight into epistemically beneficial stubbornness on the part of researchers. In conversation with (...) extant formal models, recent empirical research, and a novel agent-based model of my own I explore whether the epistemic goods which stubbornness can secure—disagreement and diversity—are attainable through less-costly methods. I make the case that they are, at least in part, and also use my modeling results to show that if stubbornness is scientifically valuable, it still involves a willingness to change one’s mind.

¿Qué tipo de agencia es necesaria para la personalidad jurídica? ¿Cuáles son los requisitos cognitivos y racionales que los sistemas legales asumen acerca de los sujetos de la ley? ¿Cómo es que los seres humanos cumplen con estos requisitos? En trabajo previo (Cáceres y Montemayor, 2016), hemos argumentado que estas preguntas requieren un nuevo acercamiento a la teoría del derecho, basado en hallazgos recientes en ciencia cognitiva, que van más allá de tratamientos teóricos neuro-legales contemporáneos. Aquí construimos sobre esta propuesta, (...) ahora enfocándonos en cuestiones de agencia y normatividad, incluyendo tipos de agencia que son relevantes para la epistemología social. La conclusión principal del artículo es que los muy estrictos requisitos cognitivos que se asumen sobre las capacidades explícitas de racionalidad de los agentes cognitivos, presupuestos por la ley, no sólo son incompatibles con los hallazgos en psicología, sino que un análisis sistemático de la agencia moral y epistémica también es necesario para poder entender la normatividad legal. El argumento principal es que tipos de agencia colectiva, moral y epistémica, difieren de la agencia individual, la cual también debe distinguirse como moral y epistémica. Fundamentalmente, la agencia colectiva difiere de la individual no sólo con base en diferencias con respecto a la racionalidad, sino también con base en los criterios de integración informativa. Varias consecuencias de este análisis son evaluadas, incluyendo aspectos concernientes a integración informativa para juicios y decisiones, comunicación fiable para la agencia epistémica, y la integración de consideraciones morales en el razonamiento jurídico. Una revisión comprensiva de la noción de “autonomía” es justificada por esta propuesta, en parte porque los requisitos comunes para la personalidad y autonomía jurídica son muy demandantes e inadecuados en muchos casos, y en parte porque la agencia colectiva debe tomarse en consideración como un tipo fundamental de agencia legal responsable para procesos de integración informativa. Basándonos en la distinción entre formas epistémicas y morales de razonamiento, explicamos cómo los sistemas legales necesitan de altos niveles de integración cognitiva para la responsabilidad legal a nivel colectivo.

Like non-verbal communication, paralinguistic communication is rooted in anatomical and physiological factors. Paralinguistic form-meaning relations arise from the way these affect speech production, with some fine-tuning by the cultural and linguistic context. The effects have been classified as “biological codes,” following the terminological lead of John Ohala's Frequency Code. Intonational morphemes, though arguably non-arbitrary in principle, are in fact heavily biased toward these paralinguistic meanings. Paralinguistic and linguistic meanings for four biological codes are illustrated. In addition to the Frequency Code, (...) the Effort Code, and the Respiratory Code, the Sirenic Code is introduced here, which is based on the use of whispery phonation, widely seen as being responsible for the signaling and perception of feminine attractiveness and sometimes used to express interrogativity in language. In the context of the evolution of language, the relations between physiological conditions and the resulting paralinguistic and linguistic meanings will need to be clarified. (shrink)

Después de enseñar la asignatura de Ética, y de la aplicar unas normas familiares escolares tradicionales, los estudiantes no se apropian de elementos éticos por varias causas: no les ven utilidad, no comprenden el contexto, o simplemente no les afecta, anulando cualquier interés al respecto. Esto impide que su obrar en la cotidianidad no sea tolerante en su ambiente escolar, generando dificultades en el docente para mediar comportamientos opuestos a una cultura de paz. Ante esto, se propone la Filosofía para (...) Niños (FpN) como apuesta ético-política que permita robustecer el pensamiento crítico, creativo y cuidadoso para mirar hacia una cultura de paz. Diego Pineda, el fundador de FpN en Colombia, sostiene que es necesario desarrollar en los estudiantes habilidades de pensamiento que, adicionales a conocimientos éticos-ciudadanos, los lleve a tomar decisiones acertadas en el abordaje pacífico del conflicto. El desarrollo paulatino del pensamiento, la cercanía a las comunidades de indagación, la incursión en habilidades cognitivas y éticas producto de las herramientas pedagógicas propias del programa de FpN, constituyen una preparación para asumir posiciones argumentadas frente a dilemas que acontecen dentro de los conflictos escolares, ello facilitará al estudiante estructurarse y lograr tomar decisiones iluminadas por la razón.

Abordagens pós-cognitivistas mais recentes têm lançado duras críticas à noção de representação mental, procurando ao invés disso pensar a mente e a cognição em termos de ações corporificadas do organismo em seu meio. Embora concordemos com essa concepção, não está claro que ela implique necessariamente a rejeição de qualquer tipo de vocabulário representacional. O objetivo deste artigo é argumentar que representações podem nos comprar uma dimensão explicativa adicional não disponível por outros meios e sugerir que, ao menos em alguns casos, (...) elas podem participar da explicação de performances ou capacidades cognitivas. A noção de representação apresentada, como deixaremos claro ao longo do artigo, não viola os preceitos metodológicos mais caros à cognição 4E em geral e ao enativismo em particular, podendo, portanto, ser utilizada como uma ferramenta teórica útil em investigações sobre a natureza corporificada e situada da mente.

A recent article by Burch-Brown and Archer provides compelling arguments that biodiversity is either a natural kind or a pragmatically-valid scientific entity. I call into question three of these arguments. The first argument contends that biodiversity is a Homeostatic Property Cluster. I respond that there is no plausible homeostatic mechanism that would make biodiversity an HPC natural kind. The second argument proposes that biodiversity is a multiply-realizable functional kind. I respond that there is no shared function to ground this account. (...) The final, and strongest, argument, is that biodiversity is an ineliminable explanans and explanandum in various subdisciplines of biology. I argue that once we look at the details of the relevant research, not only does biodiversity in a broad sense not function in explanatory roles, but we must eliminate biodiversity in favor of more specific concepts in order to make sense of the leading explanations in contemporary ecology and conservation science.

This book traces the origins and evolution of cybersemiotics, beginning with the integration of semiotics into the theoretical framework of cybernetics and information theory. The book opens with chapters that situate the roots of cybersemiotics in Peircean semiotics, describe the advent of the Information Age and cybernetics, and lay out the proposition that notions of system, communication, self-reference, information, meaning, form, autopoiesis, and self-control are of equal topical interest to semiotics and systems theory. Subsequent chapters introduce a cybersemiotic viewpoint on (...) the capacity of arts and other practices for knowing. This suggests pathways for developing Practice as Research and practice-led research, and prompts the reader to view this new configuration in cybersemiotic terms. Other contributors discuss cultural and perceptual shifts that lead to interaction with hybrid environments such as Alexa. The relationship of storytelling and cybersemiotics is covered at chapter length, and another chapter describes an individual-collectivity dialectics, in which the latter constrains the former, but the former fuels the latter. The concluding chapter begins with the observation that digital technologies have infiltrated every corner of the metropolis - homes, workplaces, and places of leisure - to the extent that cities and bodies have transformed into interconnected interfaces. The book challenges the reader to participate in a broader discussion of the potential, limitations, alternatives, and criticisms of cybersemiotics. (shrink)

Statistical Default Logic (SDL) is an expansion of classical (i.e., Reiter) default logic that allows us to model common inference patterns found in standard inferential statistics, e.g., hypothesis testing and the estimation of a population‘s mean, variance and proportions. This paper presents an embedding of an important subset of SDL theories, called literal statistical default theories, into stable model semantics. The embedding is designed to compute the signature set of literals that uniquely distinguishes each extension on a statistical default theory (...) at a pre-assigned error-bound probability.
