Este artículo analiza el fenómeno de los populismos y su relación con la participación ciudadana desde un punto de vista crítico. Se destaca que con el uso del lenguaje se generan afinidades entre conceptos, como el de populismo y una mayor participación por parte de los ciudadanos, cuando, paradójicamente, suele producirse el fenómeno contrario, a saber, una o varias personas, en muchos casos autoproclamadas como la voz del pueblo, son las que determinan el porvenir de los ciudadanos, amparándose, precisamente, en (...) una suerte de legitimación popular que es, cuando menos, discutible. Por ello se da una contradicción no aparente entre populismo y participación ciudadana ya que se excluye de las decisiones políticas a los ciudadanos en aras de una aparente mayor capacidad de decisión del pueblo.

En este artículo describiremos la vitalidad del sistema fonológico del mapudungun hablado por escolares pewenches de la Provincia del Biobío, VIII Región. Específicamente, nos hemos propuesto: a) Determinar los fonos/fonemas, y su fonotaxis, que se relevan como indicadores de vitalidad, b) Identificar las transferencias fonético-fonológicas presentes en la fonología del pewenche hablado por estos escolares y c) Interpretar las transferencias encontradas en términos del grado de vitalidad de la fonología de la lengua. La muestra está conformada por un grupo de (...) 20 escolares bilingües de entre 12 y 15 años de edad, que se encuentran cursando 7° y 8° año básico en escuelas rurales pertenecientes a dos comunidades pewenches del valle del Queuco, en la comuna de Alto Biobío. Para la recolección del material fonológico, se aplicó a los participantes una lista léxica de 65 ítems, material que se complementó con la narración oral en mapudungun de un cuento. Según nuestros datos, hemos podido constatar la existencia de una serie de rasgos fónicos en el mapudungun hablado por los escolares pewenches que obedece a la influencia de las estructuras fonológicas del castellano. Sin embargo, el grado y la difusión de los fenómenos de transferencia se desarrollan de manera heterogénea en ambas comunidades en estudio, debido, entre otros factores, a la intensidad del contacto. In this article we will describe the vitality of the phonological system Mapudungun spoken by Pewenche schoolchildren from the Biobío province, VIII Region. We intend: a) To determine the phones/phonemes, and their phonotactics, which are revealed as vitality markers. b) To identify the phonetic-phonological transferences which are present in the Pewenche spoken by these schoolchildren, and, c) To interpret the transferences found in terms of the degree of the language phonological vitality. The sample is composed of 20 bilingual schoolchildren from 12 to 15 years old, who are in 7th and 8th grade in rural primary schools belonging to two Pehuenche comunities from Valle del Queuco, in the city of Alto Biobío. To collect the phonological material, we applied a 64-item lexical list, which was complemented with the oral narration of a tale in Mapudungun. According to our data, we have been able to verify the existence of a series of phonic features in the Mapudungun spoken by Pewenche schoolchildren, which originate because of the influence of the Spanish phonological structure. However, the degree and spread of the transference phenomena develop in a heterogeneous way in both of the studied communities. due to the contact intensity, among other possible factors. (shrink)

This article provides a comprehensive review of the rather intricate relationship between contemporary environmental ethics, understood as a philosophical branch, and ancient philosophy. While its primary focus is on Western philosophy, it also includes some brief yet crucial considerations about the influence of Eastern traditions of thought on environmental ethics. Aside from the introduction in the first section, the discussion is organised into three main sections. In the Reception: Ancient philosophy in environmental ethics section, I review the initial reception of (...) ancient philosophy in contemporary environmental ethics. Next, in the Reaction: Environmental ethics in ancient philosophy scholarship section, I examine how the scholarship in AP responded to this early reception. I conclude, in the final section, with some constructive suggestions for future research. (shrink)

Abstractabstract:The present article reassesses Aristotle's views on the relationship between ethical character and the natural environment. The standard reading, to the effect that Aristotle endorsed environmental determinism, is rejected. The discussion invites a more careful examination of Aristotelian texts commonly adduced to support the orthodox reading, while also providing a clear account of what environmental determinism is. I argue that the textual evidence presented by defenders of the standard reading does not match that account. All in all, I conclude, we (...) are not authorized to invoke Aristotle's views on the relationship between natural environment and human beings in order to discredit his ethical and political project.

Jonathan Schaffer has provided three putative counterexamples to the transitivity of grounding, and has argued that a contrastive treatment of grounding is able to provide a resolution to them, which in turn provides some motivation for accepting such a treatment. In this article, I argue that one of these cases can easily be turned into a putative counterexample to a principle which Schaffer calls differential transitivity. Since Schaffer's proposed resolution rests on this principle, this presents a dilemma for the contrastivist: (...) either he dismisses the third case, which weakens the motivation for accepting his treatment of grounding, or else he accepts it, in which case he is faced with a counterexample to a principle that his proposed resolution to the original cases depends on. In the remainder of the article, I argue that the prima facie most promising strategy the contrastivist could take, which is to place some restriction on which contrastive facts are admissible so as to rule out the purported counterexample to differential transitivity, faces some important difficulties. Although these difficulties are not insurmountable, they do pose a substantial challenge for the contrastivist. (shrink)

According to the cohabitation account, all the persons that result from a fission event cohabit the same body prior to fission. This article concerns a problem for this account. Suppose Manuel and Jimena are suffering from an equally painful migraine. Unlike Jimena, however, Manuel will undergo fission. Assuming you have a spare painkiller, whom should you give it to? Intuitively, you have no more reason to give it to one or the other. The problem is that the cohabitation account suggests (...) otherwise. According to the account, there are two persons cohabiting Manuel’s body, in which case you should arguably give them the pill, since doing so alleviates the pain of more beings. One response argues that the two persons cohabiting Manuel’s body share one pain. Thus, giving them the pill alleviates no more pain than giving it to Jimena, and therefore you have no more reason to do one or the other. The goal of this article is to show that this response fails. (shrink)

Kris McDaniel has recently defended a criterion for being an ontological pluralist that classifies the quantifier variantist as one. In this paper, I argue that this is a mistake. There is an important difference between the two views, which is sometimes obscured by a common view in the metaphysics of fundamentality. According to the simple analysis, a language is ideal—it allows for a maximally metaphysically perspicuous description of reality—just in case all its primitives are perfectly natural. I argue that this (...) analysis struggles to distinguish quantifier variance from ontological pluralism, and then I discuss various accounts that can do better. I then propose a criterion for being an ontological pluralist that does not misclassify the quantifier variantist. Finally, I discuss some additional advantages of my proposal. (shrink)

Are we Human Beings Unable of God? José Cobo maintains that the worldview of contemporary man does not allow him to believe in the sense that the first Christians believed.

On the other hand, we rectify certain intellectual resources with which (...) we intend to get out of this situation. (shrink)

El presente artículo es un estudio comparativo donde se argumenta la relación disonante entre las obras de Schmitt y Benjamin sobre la estética barroca. Se defiende que la diferencia entre ambos consiste en su concepción de lo político. Para Benjamin, son dos los aspectos fundamentales del Trauerspiel alemán: 1) la diferencia entre drama barroco y tragedia clásica y 2) el recurso a la alegoría como técnica de expresión. Schmitt, por su parte, encuentra lo singular del drama barroco en la irrupción (...) del tiempo histórico-político dentro de la forma estética. Para el crítico berlinés, lo alegórico debe estudiarse desde la filosofía de la historia, mientras que para Schmitt lo decisivo es lo político, ejecutado a través de la soberanía y la decisión. Tal es la línea argumental del presente estudio. This paper is a comparative study about the Works of Benjamin and Schmitt on the baroque art. It argues that the specific difference between them most be found in their concept of the political. For Benjamin there is a difference between tragedy and drama, the german Trauerspiel it is an allegorical approach to thingsand history. Schmitt argues that the singularity of baroque drama is the irruption of time in the plastic form. These are the points that the paper proposes. (shrink)

Alternative food networks are exemplified by organic, fair trade and local foods, and promote forms of food provisioning that are ‘corrective’ to conventional agriculture and food systems. Despite enthusiasm for AFNs, scholars have increasingly interrogated whether inequalities are perpetuated by AFNs. Reproduction of gender inequality in AFNs, particularly at the level of consumption, has often been left empirically unexamined, however. This is problematic given that women continue to be predominantly responsible for food provisioning in the US, and that this responsibility (...) can lead to negative physical, psychological and social outcomes. Using quantitative methods and data from the 2012 Ohio Survey of Food, Agriculture, and Environmental Issues, this paper examines the extent to which gender inequality in the division of labor is reproduced in AFNs by focusing on the potential persistence of gender inequality in food provisioning among AFN participants. Findings suggest that among AFN participants, particularly those utilizing local food systems, women, compared to men, remain predominantly responsible for food provisioning, spend more time in food provisioning, and engage in more food provisioning from scratch. This research confirms that food provisioning remains a gendered act amongst AFN participants, calling attention to the persistence of gender inequality in AFNs. The paper concludes by suggesting that AFNs are positioned as a place to create change, albeit small scale, in the gendered division of household labor in the US, and provides some practical suggestions for how this might occur.

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)

Our pains can be more or less intense, our mental imagery can be more or less vivid, our perceptual experiences can be more or less striking. These degrees of intensity of conscious experiences are all manifestations of a phenomenal property I call mental strength. In this article, I argue that mental strength is a domain-general phenomenal magnitude; in other words, it is a phenomenal quantity shared by all conscious experiences that explains their degree of felt intensity. Mental strength has been (...) largely overlooked in favor of mental states’ type, representational contents, domain-specific phenomenology, or processes such as attention. Considering mental strength in our reflections about the mind illuminates debates about the relation of representational contents and phenomenal character, and it also helps address questions about the structure and functions of consciousness. Mental strength provides a unifying construct to model what is shared in the phenomenology of different types of conscious experiences. (shrink)

It will interest global scholars in utopian studies and also Latin Americanists, especially those in the field of Colonial studies. The close reading of five utopian works...

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)

Arguably the most foundational principle in perception research is that our experience of the world goes beyond the retinal image; we perceive the distal environment itself, not the proximal stimulation it causes. Shape may be the paradigm case of such “unconscious inference”: When a coin is rotated in depth, we infer the circular object it truly is, discarding the perspectival ellipse projected on our eyes. But is this really the fate of such perspectival shapes? Or does a tilted coin retain (...) an elliptical appearance even when we know it’s circular? This question has generated heated debate from Locke and Hume to the present; but whereas extant arguments rely primarily on introspection, this problem is also open to empirical test. If tilted coins bear a representational similarity to elliptical objects, then a circular coin should, when rotated, impair search for a distal ellipse. Here, nine experiments demonstrate that this is so, suggesting that perspectival shapes persist in the mind far longer than traditionally assumed. Subjects saw search arrays of three-dimensional “coins,” and simply had to locate a distally elliptical coin. Surprisingly, rotated circular coins slowed search for elliptical targets, even when subjects clearly knew the rotated coins were circular. This pattern arose with static and dynamic cues, couldn’t be explained by strategic responding or unfamiliarity, generalized across shape classes, and occurred even with sustained viewing. Finally, these effects extended beyond artificial displays to real-world objects viewed in naturalistic, full-cue conditions. We conclude that objects have a remarkably persistent dual character: their objective shape “out there,” and their perspectival shape “from here.”. (shrink)

To make the case for non-conceptualism, Heck draws on an apparent dichotomy between linguistic and iconic representations. According to Heck, whereas linguistic representations have conceptual content, the content of iconic representations is non-conceptual. Based on the case of cartographic systems, the authors criticize Heck’s dichotomous distinction. They argue that maps are composed of semantically arbitrary elements that play different syntactic roles. Based on this, they claim that maps have a predicative structure and convey conceptual content. Finally, the authors argue that, (...) despite their differences, maps and sentences can logically interact with each other through heterogeneous inferences. These considerations not only challenge the view that conceptual content and inferential processes necessarily involve linguistic representations; furthermore, they provide a new perspective for thinking about maps, their semantics and syntax, and their interaction with linguistic systems.

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.

Implementing corporate social responsibility (CSR) in supply chains is not a trivial task. In fact, many firms in recent years have publicly proclaimed that in order to keep their CSR commitments, they had to reduce reliance on external suppliers by vertically integrating their operations. Our aim in this article is to examine whether there is truly a relationship between a firm’s CSR performance and its level of vertical integration. Drawing on a multi-industry sample of 2,715 firm-year observations, and after addressing (...) endogeneity concerns, we demonstrate that firms with higher CSR performance tend to vertically integrate more (or, outsource less). We also demonstrate that this tendency is weaker for firms that have higher degrees of asset specificity or international diversification. Our core conclusion is that CSR performance and outsourcing are at odds, but firms can reconcile this tension by deepening their collaborations with suppliers. (shrink)

Metacognition is the capacity to evaluate the success of one's own cognitive processes in various domains; for example, memory and perception. It remains controversial whether metacognition relies on a domain-general resource that is applied to different tasks or if self-evaluative processes are domain specific. Here, we investigated this issue directly by examining the neural substrates engaged when metacognitive judgments were made by human participants of both sexes during perceptual and memory tasks matched for stimulus and performance characteristics. By comparing patterns (...) of fMRI activity while subjects evaluated their performance, we revealed both domain-specific and domain-general metacognitive representations. Multivoxel activity patterns in anterior prefrontal cortex predicted levels of confidence in a domain-specific fashion, whereas domain-general signals predicting confidence and accuracy were found in a widespread network in the frontal and posterior midline. The demonstration of domain-specific metacognitive representations suggests the presence of a content-rich mechanism available to introspection and cognitive control. (shrink)

Studying the neural correlates of conscious awareness depends on a reliable comparison between activations associated with awareness and unawareness. One particularly difficult confound to remove is task performance capacity, i.e. the difference in performance between the conditions of interest. While ideally task performance capacity should be matched across different conditions, this is difficult to achieve experimentally. However, differences in performance could theoretically be corrected for mathematically. One such proposal is found in a recent paper by Lamy, Salti and Bar-Haim [Lamy (...) D, Salti M, Bar-Haim Y. Neural correlates of subjective awareness and unconscious processing: an ERP study. J Cognitive Neurosci 2009,21:1435-46], who put forward a corrective method for an electroencephalography experiment. We argue that their analysis is essentially grounded in a version of High Threshold Theory, which has been shown to be inferior in general to Signal Detection Theory. We show through a series of computer simulations that their correction method only partially removes the influence of perfor- mance capacity, which can yield misleading results. We present a mathematical correction method based on Signal Detection Theory that is theoretically capable of removing performance capacity confounds. We discuss the limitations of mathemati- cally correcting for performance capacity confounds in imaging studies and its impact for theories about consciousness. (shrink)

This is the first book-length study of Descartes's metaphysics to place it in its immediate historical context, the Late Scholastic philosophy of thinkers such as Suárez against which Descartes reacted. Jorge Secada views Cartesian philosophy as an 'essentialist' reply to the 'existentialism' of the School, and his discussion includes careful analyses and original interpretations of such central Cartesian themes as the role of scepticism, intentionality and the doctrine of the material falsity of ideas, universals and the relation between sense (...) and understanding, causation and the proofs of the existence of God, the theory of substance, and the dualism of mind and matter. His study offers a picture of Descartes's metaphysics that is both novel and philosophically illuminating. (shrink)

Structural changes in the agriculture and food system have resulted in larger but fewer farms, while increasing populations in urban areas have pushed development into rural areas. Despite these changes, little research has examined the concern of individuals with regards to loss of farmland and how this may vary based on geography. Building on Bell’s argument that the rural–urban continuum still exists and remains an important part of rural residents’ identity, in this article we examine residents’ concern over loss of (...) farmland as a result of urban growth. We pay particularly close attention to urban–rural differences over concern with loss of farmland. Utilizing survey data collected from over 400 households in the Treasure Valley, a region of the western United States, our results indicate that rural residents show greater levels of concern with farmland loss when compared to their urban counterparts.

The article presents some of the results of the research project Lúdica y juego en la educación infantil: construcción conceptual–Play and Games in Early Childhood Education: A Conceptual Construct–financed by the Vicerrectoría de Investigaciones of the Universidad Pedagógica y Tecnológica de Colombia, Tunja, Boyacá, Colombia. The aim was to identify and explore the conceptions of what the Campamento Filosófico (Philosophy Camp) represents for its participants within the framework of the project Filosofía e infancia (Philosophy and Childhood). This study takes a (...) qualitative approach, for which semi-structured interviews were used as an instrument for data collection. Also, Atlas.ti 8® software was used for data analysis. An open, axial and selective coding was carried out, in which the emerging categories of the analysis were “experience,” “encounter,” “learning,” “self-care” and “body”. As a result of this conceptualization, it was found that philosophy camps are scenarios that make possible a relationship between university learning environments and primary, elementary and middle school educational contexts. They also enable an experience of the dialogic encounter between different perspectives on the same philosophical topic. Through the Philosophy Camp, philosophy is brought to the school, and the encounter with childhood - as a state, attitude and possibility - fosters spaces for thought, friendship and interaction.

Abstract“Sign stimuli” elicit specific patterns of behavior when an organism's motivation is appropriate. In the toad, visually released prey-catching involves orienting toward the prey, approaching, fixating, and snapping. For these action patterns to be selected and released, the prey must be recognized and localized in space. Toads discriminate prey from nonprey by certain spatiotemporal stimulus features. The stimulus-response relations are mediated by innate releasing mechanisms (RMs) with recognition properties partly modifiable by experience. Striato-pretecto-tectal connectivity determines the RM's recognition and localization (...) properties, whereas medialpallio-thalamo-tectal circuitry makes the system sensitive to changes in internal state and to prior history of exposure to stimuli. RMs encode the diverse stimulus conditions referring to the same prey object through different combinations of “specialized” tectal neurons, involving cells selectively tuned to prey features. The prey-selective neurons express the outcome of information processing in functional units consisting of interconnected cells. Excitatory and inhibitory interactions among feature-sensitive tectal and pretectal neurons specify the perceptual operations involved in distinguishing the prey from its background, selecting its features, and discriminating it from predators. Other connections indicate stimulus location. The results of these analyses are transmitted by specialized neurons projecting from the tectum to bulbar/spinal motor systems, providing a sensorimotor interface. Specific combinations of such projective neurons – mediating feature- and space-related messages – form “command releasing systems” that activate corresponding motor pattern generators for appropriate prey-catching action patterns.
