This chapter explores the possibility of integrating the enactive and the Free Energy Principle’s (FEP) approaches to life and mind. Both frameworks have been linked to the life-mind continuity thesis, but recent debates challenge their potential integration. Critics argue that the enactive approach, rooted in autopoiesis theory, has an internalist view of life and a contentful view of cognition, making it challenging to account for adaptive behavior and minimal cognition. Similarly, some find the FEP’s stationary view of life biologically implausible. (...) Here, I address recent challenges in integrating the FEP and enactivism, thereby focusing on the life-mind continuity thesis. I suggest that the FEP, without explicitly defining life and mind, can be used to model the autopoietic dynamics of organisms. Additionally, I argue that the enactive conception of cognition as sense-making overcomes issues associated with contentful views of cognition. Furthermore, I refute the misinterpretation of the FEP’s assertion of stationary organisms, allowing for the modeling of enactive adaptive behavior through free energy minimization. Ultimately, I offer a constructive and interactionist approach to life and mind, transcending internalist and externalist perspectives. (shrink)

We propose a new interpretation of the equation E=mc² in special relativity by generalizing ideas of ontological emergence to fundamental physics. This allows us to propose that mass, as a property, can be considered to emerge from energy, using a well-known definition of weak ontological emergence. Einstein’s famous equation gains in this way a clearer philosophical interpretation, one that avoids the problems of previous attempts, and is fully consistent with the kinematic properties of special relativity, while yielding fresh insights concerning (...) the nature of mass.

The relationship between “Towards a Critique of Violence” (1921) and the work of Franz Kafka has been well established by several critical studies devoted to Walter Benjamin. However, it is striking that Benjamin himself, already well acquainted with the work of the Czech writer in 1921, never made any comment to Kafka’s work in this essay, and, more broadly, in any of the related texts that make up the project on the ‘Critique of Violence’. In this article, we analyze a (...) set of notions (Entstellung, Entsühnung, Zurechstellen) that allow us to establish a mediated relationship between this essay and the articles and letters that Benjamin devoted to Kafka in the 1930s. This relationship takes us back to the only piece in which Benjamin carries out an autonomous treatment of the “category of justice” (1916) in which he identifies -as it will happen eighteen years later, in the essay on Kafka (1934)- the locus of justice in the “non-violence”, thus untying the knot that binds in a perhaps indiscernible way in the Jewish tradition the notions of “messianism” and “violence”.

ABSTRACT:Business ethics research has long been interested in understanding the conditions under which ethical consumption is consistent versus context-dependent. Extant research suggests that many consumers fail to make consistent ethical consumption decisions and tend to engage in ethical decisions associated with ingroup identity cues. To fill this gap, four experiments examine how construal levels moderate the influence of ingroup versus outgroup identity cues in ethical consumption. The studies support the contention that when consumers use concrete construal to process information, they (...) will focus on ingroup cues and make ethical consumption decisions that are aligned with ingroup biases. However, when consumers use abstract construal, they will act more consistently with their inner goals rather than focusing on ingroup and outgroup cues. Social goodwill, which indicates desires to give back to society, is identified as mediating the effects. The findings have important implications for ethical consumption and social influence literature. (shrink)

One of Heidegger’s most important descriptions of bodily existence can be found in his Nietzsche lectures. This paper aims to elucidate this “metaphysics of the body” both in relation to Heidegger’s Leibniz-interpretation in the later Marburg lectures as well as in the context of his later thought. Leibniz and Nietzsche are Heidegger’s points of departure in the attempt to think the difference between θεωρία and πραξις beyond Being and Time: It is only by understanding their relationship, through a radical re-thinking (...) of the problem of corporeality, no longer as a noun (der Leib) but as a verb (leiben), that one can possibly move beyond every traditional dualism, between theory and praxis but also and most notably between being and becoming.

Scientific concepts are defined by metaphors. These metaphors determine what atten- tion is and what count as adequate explanations of the phenomenon. The authors analyze these metaphors within 3 types of attention theories: (a) --cause-- theories, in which attention is presumed to modulate information processing (e.g., attention as a spotlight; attention as a limited resource); (b) --effect-- theories, in which attention is considered to be a by-product of information processing (e.g., the competition meta- phor); and (c) hybrid theories that combine (...) cause and effect aspects (e.g., biased- competition models). The present analysis reveals the crucial role of metaphors in cognitive psychology, neuroscience, and the efforts of scientists to find a resolution to the classic problem of cause versus effect interpretations.

Morphological EvoDevo is a field of biological inquiry in which explicit relations between evolutionary patterns and growth or morphogenetic processes are made. Historically, morphological EvoDevo results from the coming together of several traditions, notably Naturphilosophie, embryology, the study of heterochrony, and developmental constraints. A special feature binding different approaches to morphological EvoDevo is the use of formalisms and mathematical models. Here we will introduce anatomical network analysis, a new approach centered on connectivity patterns formed by anatomical parts, with its own (...) concepts and tools specifically designed for the study of morphological EvoDevo questions. Riedl’s concept of burden is tightly related to the use of anatomical networks, providing a nexus between the evolutionary patterns and the structural constraints that shape them. (shrink)

Microbes can influence host physiology and behavior in many ways. Here we review evidence suggesting that some microbes can contribute to host stress (and other microbes can contribute to increased resilience to stress). We explain how certain microbes, which we call “stress microbes,” can potentially benefit evolutionarily from inducing stress in a host, gaining access to host resources that can help fuel rapid microbial replication by increasing glucose levels in the blood, increasing intestinal permeability, and suppressing the immune system. Other (...) microbes, which we term “resilience microbes,” can potentially benefit from making hosts more resilient to stress. We hypothesize that “stress microbes” use a fast life history strategy involving greater host exploitation while “resilience microbes” use a slow life history strategy characterized by more aligned evolutionary interests with the host. In this paper, we review the evidence that microbes affect host stress and explain the evolutionary pressures that could lead microbes to manipulate host stress, discuss the physiological mechanisms that are known to be involved in both stress and microbial activity, and provide some testable predictions that follow from this hypothesis.

In a recent paper Samir Okasha has suggested an application of Arrow’s impossibility theorem to theory choice. When epistemic virtues are interpreted as ‘voters’ in charge of ranking competing theories, and there are more than two theories at stake, the final ordering is bound to coincide with the one proposed by one of the voters, provided a number of seemingly reasonable conditions are in place. In a similar spirit, Jacob Stegenga has shown that Arrow’s theorem applies to the amalgamation of (...) evidence; the ‘voters’ here are the different sources of evidence. As with Okasha’s proposal, it is not clear how to avoid Arrow’s pessimistic conclusion.In this paper we develop a novel argument that purports to show that, in typical examples, Arrow’s result does not obtain when dealing with evidence amalgamation. The reason is that we cannot escape the well-known Duhem problem: the evidence actually confirms complex conjunctions that include various auxiliary hypotheses. We argue that confirmational holism induces us to restrict the domain of a reasonable amalgamation function, thus violating one of Arrow’s conditions. The upshot is that we are now able to see the Duhem problem under a different, positive light – namely, as a phenomenon that makes the aggregation of the evidence possible in the first place, when there are at least three options on the table.

BackgroundThe outbreak of novel coronavirus disease 2019 has caused a global panic and public concern due to its mortality ratio and lack of treatments/vaccines. Reduced levels of physical activity have been reported during the outbreak, affecting the normal daily pattern.ObjectiveTo investigate the relationship of physical activity level with sleep quality and the effects of reduction physical activity levels on sleep quality.MethodsA Google form was used to address personal information, COVID-19 personal care, physical activity, and mental health of 1,907 adult volunteers. (...) Binary logistic regression was used to verify the association of physical activity parameters and sleep quality.ResultsInsufficient physical activity levels were a risk factor to have disturbed sleep pattern [OR: 1.28, 95% CI ]; however, when the BMI was added to the analysis, there was no more statistical difference [OR: 1.23, 95% CI ]. On the other hand, we found that the reduction of physical activity levels was associated with negative changes in sleep quality [OR: 1.73, 95% CI ], regardless all the confounders [OR: 1.30, 95% CI ], unless when feeling of depression was added in Model 6 [OR: 1.28, 95% CI ].ConclusionDisruption in daily physical activity routine, rather than physical activity level, negatively influences sleep quality during the COVID-19 quarantine.

Several recent findings support the notion that changes in the environment can be implicitly represented by the visual system. S. R. Mitroff, D. J. Simons, and S. L. Franconeri (2002) challenged this view and proposed alternative interpretations based on explicit strategies. Across 4 experiments, the current study finds no empirical support for such alternative proposals. Experiment 1 shows that subjects do not rely on unchanged items when locating an unaware change. Experiments 2 and 3 show that unaware changes affect performance (...) even when they occur at an unpredictable location. Experiment 4 shows that the unaware congruency effect does not depend simply on the pattern of the final display. The authors point to converging evidence from other methodologies and highlight several weaknesses in Mitroff et al.’s theoretical arguments. It is concluded here that implicit representation of change provides the most parsimonious explanation for both past and present findings. (shrink)

As it is well known, mobile phones have become a basic gadget for any individual that usually stores sensitive information. This mainly motivates the increase in the number of attacks aimed at jeopardizing smartphones, being an extreme concern above all on Android OS, which is the most popular platform in the market. Consequently, a strong effort has been devoted for mitigating mentioned incidents in recent years, even though few researchers have addressed the application of visualization techniques for the analysis of (...) malware. Within this field, the present work proposes the extension of a new technique called Hybrid Unsupervised Exploratory Plots to visualize Android malware datasets. More precisely, the novel Beta-Hebbian Learning (BHL) method is applied for the first time and validated under the frame of Hybrid Unsupervised Exploratory Plots, in conjunction with clustering methods. The informative visualization achieved provides a picture of the structure of the malware families, allowing subsequent analysis of their organization. To validate the Hybrid Unsupervised Exploratory Plot extension and its tuning, the popular Android Malware Genome dataset has been used in the experimental setting. Promising results have been obtained, suggesting that BHL applied in combination with clustering techniques in Hybrid Unsupervised Exploratory Plots are a viable resource for the visualization of malware families.

We study the possible values of the cofinality invariant for various Borel ideals on the natural numbers. We introduce the notions of a fragmented and gradually fragmented ideal and prove a dichotomy for fragmented ideals. We show that every gradually fragmented ideal has cofinality consistently strictly smaller than the cardinal invariant and produce a model where there are uncountably many pairwise distinct cofinalities of gradually fragmented ideals.

En el presente texto se evalúan las posibilidades conceptuales de una interpretación fisicalista de la conciencia. Con dicho fin se toman en cuenta posiciones representativas en el ámbito de la filosofía, así como investigaciones neurocientíficas recientes. Ambas líneas de investigación suponen el cuestionamiento de los acercamientos de sentido común al tema de la conciencia. No obstante, no suponen una completa eliminación de lo que dicho acercamiento puede representar. En este sentido, se propone una interpretación epistemológica de la perspectiva intuitiva de (...) primera persona en relación con la perspectiva científica de tercera persona. (shrink)

En el presente artículo analizaremos las condiciones históricas de los procesos de subjetividad en Neiva durante su fundación en el siglo XVII a partir de discursos coloniales en cuyos juegos de verdad estos se fueron constituyendo. El objetivo es examinar de qué manera se conformaron esos juegos de verdad a través de cuales los sujetos se relacionaron con el saber, qué reglas controlaron dicho juego y de qué manera funcionan en él. Esto implica que entender la modernidad atravesada por la (...) colonialidad exige analizar críticamente los diferentes regímenes que históricamente han operado en ella. Es decir, pensar un conjunto de normas o reglas que, imbricadas con discursos y prácticas de subjetivación, han funcionado en la historia de maneras diferentes en procura de unificar bajo un mismo paradigma las diferencias de los sujetos.

Resumen La argumentación es una forma de discurso en la que un hablante defiende una postura en una discusión. El presente trabajo se enfoca en la complejidad argumentativa y los recursos evaluativos y evidenciales que caracterizan las disputas de niños de diverso nivel socioeconómico. Se analizaron 94 disputas entre niños de 4 años y otros niños (5 a 10 años) en situaciones de juego espontáneo registradas en hogares de sectores socioeconómicos medio y bajo. El análisis identificó diferencias marginales en la (...) complejidad argumentativa entre los grupos. Por su parte se hallaron diferencias significativas en recursos de evaluativos de emocionalidad y en los evidenciales deónticos y exclamativos a favor de los sectores de nivel socioeconómico bajo. Los sectores medios registraron un mayor empleo de expresiones de causalidad y conectores. Los resultados se discuten a la luz de los hallazgos de investigaciones previas. Abstract Argumentation is a type of discourse in which a speaker defends a claim in a discussion. The present work focuses on the argumentative complexity and the evaluative and evidential resources that characterize the disputes of children of different socioeconomic levels. We analyzed 94 disputes between 4-year-old children and other children (5 to 10 years old) in situations of spontaneous play registered in homes of middle and low socioeconomic status (SES). The analysis identified marginal differences in argumentative complexity between the groups. On the other hand, significant differences were found in evaluative expressions of emotion and in deontic and exclamatory evidential markers, more frequently used by the low SES group. The mid SES group tends to use a higher number of expressions of causality and connectors. The results are discussed with reference to the findings of previous research. (shrink)

Por “tensiones temáticas” entiendo una variedad de presiones de fondo que moldean el desarrollo de ciertas controversias.

Corporate power in the constitutional educational debate in Chile Abstract: Economic elites have historically intervened in the Chilean education system, and in recent times they have consolidated their position in the framework of extreme privatization promoted by the neoliberal reform. Corporate power in education appears today as a parastatal power that affects the organization and meaning taken by educational systems, in the current context of capitalist globalization. In Chile, the constitutional principle of freedom of education has made it possible to organize an educational market, which ultimately reproduces the power of the elite over the system itself. In the context of presenting proposals for a new constitution, corporate power shows its own. What are the main elements you defend at this juncture? How is it possible to set limits on them? Key Words: Public Education; Constitutional Debate; Corporate Power; Neoliberal Education Reform.

This paper presents philosophical perspectives related to the concept of boredom from the point of view of its forms and structural modes as developed by Martin Heidegger in his lectures at the University of Freiburg during the winter semesters of 1929 and 1930. We highlight a philosophical stance often overlooked in comparison to more traditional positions in Western philosophical thought—through the proposed hermeneutic-phenomenological processes, this will allow us to interweave their philosophical images with cinematographic narratives that enrich the factual understanding (...) of modernity. For this reason, we assume boredom and its essence, “tediousness”, as the fundamental mood of our era, thus permitting other mobilities of thought that warrant a study of phenomena relating to cultural entertainment as a symptom of the modern disease that distances Dasein from meeting, questioning, and self-care.

An algebraically expandable (AE) class is a class of algebraic structures axiomatizable by sentences of the form $\forall \exists! \mathop{\boldsymbol {\bigwedge }}\limits p = q$. For a logic L algebraized by a quasivariety $\mathcal {Q}$ we show that the AE-subclasses of $\mathcal {Q}$ correspond to certain natural expansions of L, which we call algebraic expansions. These turn out to be a special case of the expansions by implicit connectives studied by X. Caicedo. We proceed to characterize all the AE-subclasses of (...) abelian $\ell $ -groups and perfect MV-algebras, thus fully describing the algebraic expansions of their associated logics. (shrink)

This thought-provoking study explores the philosophical resources provided by Hegel and Heidegger to grasp the nature of the "I" and combines those resources in a theoretical analysis of "I-hood" in its connection with nature and history, experience and myth. The "I" has a fleeting, almost elusive character in the philosophies of Hegel and Heidegger. Yet, both philosophers strive to make sense of what it means to be an "I". Their respective theories, though seemingly divergent, offer remarkable insights into the nature (...) of the "I" and its relationship to the world. Through meticulous examination, this book explores the parallel journeys of Hegel and Heidegger, tracing their respective paths towards a comprehensive conception of identity beyond the subject/object dichotomy. Moreover, this study goes beyond being an exploration of Hegel's and Heidegger's conceptions of the self, by actively employing their insights to chart a path toward a novel understanding of "I-hood". Hegel, Heidegger and the Quest for the "I" will be of interest to scholars and advanced students working on Hegel, Heidegger, history of European philosophy, and contemporary theories of subjectivity and personal identity. Offering a fresh perspective on the work of these two seminal thinkers, the book contributes to the ongoing dialogue on the nature of the self and its place in the world. (shrink)

The interdisciplinary French-American thinker René Girard (1923-2015) has been one of the towering figures of the humanities in the last half-century. The title of René Girard's first book offered his own thesis in summary form: romantic lie and novelistic truth [mensonge romantique et vérité romanesque]. And yet, for a thinker whose career began by an engagement with literature, it came as a shock to some that, in La Conversion de l'art, Girard asserted that the novel may be an “outmoded” form (...) for revealing humans to themselves. However, Girard never specified what, if anything, might take the place of the novel. This collection of essays is one attempt at answering this question, by offering a series of analyses of films that aims to test mimetic theory in an area in which relatively little has so far been offered. Does it make any sense to talk of vérité filmique? In addition, Mimetic Theory and Film is a response to the widespread objection that there is no viable “Girardian aesthetics.” One of the main questions that this collection considers is: can we develop a genre-specific mimetic analysis (of film), and are we able to develop anything approaching a “Girardian aesthetic”? Each of the contributors addresses these questions through the analysis of a film. (shrink)

The publication of the revised edition of Jeff Malpas’s Place and Experience in 2018 gives the opportunity to reconsider this book (originally published in 1999) and the debates that it originally sparked. In this article, I focus on Malpas’s characterization of space as subjective, allocentric, and objective and I approach them in conjunction with other notions and considerations that, I suggest, are useful to expand and complement Malpas’s central theses. I approach the concept of subjective space in conjunction with the (...) notion of coenaesthesis and with Heidegger’s notion of mineness (Jemeinigkeit); the concept of allocentric space by addressing Malpas’s critique of Nagel’s notion of detachment; and the concept of objective space through a discussion of the issue of perspective in light of Merleau-Ponty’s critique of Leibniz’s notion of ‘géométral’ (geometrized projection). These analyses pave the way for a discussion of some possible normative implications of the conception of place and subjectivity that emerges from Malpas’s Place and Experience against the background of Heidegger’s thought, and particularly in relation to Heidegger’s notion of dwelling (Wohnen).

After a period of neglect, the idealist and romantic philosophies that emerged in the wake of Kant's revolutionary writings have once more become important foci of philosophical interest, especially in relation to the question of the role of religion in human life. By developing and reinterpreting basic Kantian ideas, an array of thinkers including Schelling, Hegel, Friedrich Schlegel, Hölderlin and Novalis transformed the conceptual framework within which the nature of religion could be considered. Furthermore, in doing so they significantly shaped (...) the philosophical perspectives from within which later thinkers such as Feuerbach, Kierkegaard, Wagner and Nietzsche could re-pose the question of religion. This volume explores the spaces opened during this extended period of post-Kantian thinking for a reconsideration of the place of religion within the project of human self-fashioning. (shrink)

The Relationship of Philosophy to Religion Today is a collection of texts authored by philosophers with an interest in contemporary philosophy of religion, its merits and its limitations. The collection has been stimulated by such questions as: "What ought philosophy of religion be?" and "How ought philosophy relate to religion today?" In pursuing such questions, the editors have asked the contributors to offer their insights and reflections on issues that they see as important to contemporary philosophy of religion, with the (...) goal of producing a collection of texts offering the reader a variety of perspectives without privileging any particular philosophical, religious or irreligious orientation. The book covers such themes as the relationship between religion and modernity, faith in keeping with reason, contemplation, the merits and limitations of the atheism, and the relationship between philosophy, religion and politics.

A function is algebraic on an algebra if it can be implicitly defined by a system of equations on. In this note we give a semantic characterization for algebraic functions on quasiprimal algebras. This characterization is applied to obtain necessary and sufficient conditions for a quasiprimal algebra to have every one of its algebraic functions be a term function. We also apply our results to particular algebras such as finite fields and monadic algebras.

Le point de départ de cet article est la thèse développée en 1991 par Isabelle Combès et Thierry Saignes sur la naissance de l’ethnie et l’identité chiriguano, « essentiellement » métisses. Le rapport au métissage des Chiriguano et Chané semble paradoxal. Bien qu’ils soient considérés comme un exemple paradigmatique de métissage amérindien, certains points de vue contemporains condamnent l’ethnie à la disparition en raison, précisément, du métissage avec les Blancs. Les Chiriguano et Chané, quant à eux, rejettent aujourd’hui toute idée (...) de mélange, se proclamant seulement « Guaraní ». À partir d’une double étude de cas (l’Isoso bolivien et le nord-ouest argentin), on relativise d’abord le postulat de la complète absorption des Chané dans l’ensemble chiriguano ; on analyse ensuite les différents types de métissage existants, et leur relation dans un schéma asymétrique que crée une véritable échelle de valeurs entre différentes ethnies. On suggère finalement que l’ambivalence idéologique qui entoure le métissage découle précisément du fait qu’il s’agit d’une construction elle-même métisse, produit de la fusion entre les idéologies chané et guaraní.
