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)

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)

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.

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)

Consciousness and confidence seem intimately related. Accordingly, some researchers use confidence ratings as a measure of, or proxy for, consciousness. Rosenthal discusses the potential connections between the two, and rejects confidence as a valid measure of consciousness. He argues that there are better alternatives to get at conscious experiences such as direct subjective reports of awareness (i.e. subjects’ reports of perceiving something or of the degree of visibility of a stimulus). In this chapter, we offer a different perspective. Confidence ratings (...) in general, and metacognitive measures in particular, may offer important advantages over subjective ratings. The arguments we offer here are supported by empirical, practical and socio-strategic considerations. However, we do not suggest consciousness and confidence are interchangeable. We recognize the limitations of confidence ratings in some experimental designs and for some research questions. Nevertheless, we also address a potential conceptual link between consciousness and confidence that stems from Rosenthal’s very own work on mental quality space theory. (shrink)

To find the neural substrates of consciousness, researchers compare subjects’ neural activity when they are aware of stimuli against neural activity when they are not aware. Ideally, to guarantee that the neural substrates of consciousness—and nothing but the neural substrates of consciousness—are isolated, the only difference between these two contrast conditions should be conscious awareness. Nevertheless, in practice, it is quite challenging to eliminate confounds and irrelevant differences between conscious and unconscious conditions. In particular, there is an often-neglected confound that (...) is crucial to eliminate from neuroimaging studies: task performance. Unless subjects’ task performance is matched (and hence perceptual signal processing is matched), researchers risk finding the neural correlates of perception, rather than conscious perception. Here, we discuss the theoretical motivations for the performance matching framework and review empirical demonstrations of, and theoretical inferences derived from, obtaining differences in consciousness while controlling for task performance. We summarize signal detection theoretic modeling frameworks that explain how it is that we can derive performance-matched differences in consciousness without the effect being trivially driven by differences in criterion setting, and also provide principles for designing experimental paradigms that yield performance-matched differences in awareness. Finally, we address potential technical and theoretical issues that stem from matching performance across conditions of awareness, and we introduce the notion of “triangulation” for designing comprehensive experimental sets that can better reveal the neural substrates of consciousness.

When visual attention is directed away from a stimulus, neural processing is weak and strength and precision of sensory data decreases. From a computational perspective, in such situations observers should give more weight to prior expectations in order to behave optimally during a discrimination task. Here we test a signal detection theoretic model that counter-intuitively predicts subjects will do just the opposite in a discrimination task with two stimuli, one attended and one unattended: when subjects are probed to discriminate the (...) unattended stimulus, they rely less on prior information about the probed stimulus’ identity. The model is in part inspired by recent findings that attention reduces trial-by-trial variability of the neuronal population response and that they use a common criterion for attended and unattended trials. In five different visual discrimination experiments, when attention was directed away from the target stimulus, subjects did not adjust their response bias in reaction to a change in stimulus presentation frequency despite being fully informed and despite the presence of performance feedback and monetary and social incentives. This indicates that subjects did not rely more on the priors under conditions of inattention as would be predicted by a Bayes-optimal observer model. These results inform and constrain future models of Bayesian inference in the human brain. (shrink)

We draw from upper echelons theory to investigate whether the presence of a chief sustainability officer (CSO) is associated with better corporate environmental performance in highly polluting industries. Such firms are under strong pressure to remediate environmental damage, to comply with regulations, and to even exceed environmental standards. CSOs in these firms are likely to be hired as legitimate agents to lead and successfully implement environmental strategy aimed at reducing pollution levels. Interestingly and contrary to our expectations, we found that (...) the presence of a CSO is associated with higher levels of pollution emissions. Nonetheless, we found that the CSO has a positive influence on a firm’s environmental performance if faced with strict environmental regulations. We argue that the enforcement of environmental regulations enhances monitoring and accountability of pollution emissions. The sample for this study comprised all the S&P 500 firms required by the Environmental Protection Agency to annually report their toxic emissions to the Toxic Release Inventory. Data were collected for a 6-year period from 2006 to 2011. We used a panel data regression and employed propensity score matching to correct for potential endogeneity problems. (shrink)

Dynamic Theodicy (DT) is a broad concept we bring up to designate some modern Philosophical Theology attempts to reconcile the necessary and perfect existence of God with the contingent characteristics of human life. In this paper we analyze such approaches and discuss how they have become incomprehensible because the metaphysical assumptions implicit in these explanations have lost their intrinsic relation to the natural human desire for salvation. In the first part we show Charles Hartshorne's DT-model, arising from the modal logic (...) of perfection, and the modern rational problems of this position in making infinite-necessary Being (God) and finite-contingent being (human) compatible. We note that at the heart of the contradictions in this DT account is a dialectical mode of thinking that makes it difficult to find a correct solution to this dichotomy, and to assume a human desire that could be considered related to lifelong goals. In the second part, supported by the proposal of Hans Urs von Balthasar's DT, we develop the concepts of bodily vulnerability, corporeal intentionality, and natural desire for salvation, which come from an Aristotelian-Thomistic thought. This theory is established in order to build an argument, following Alasdair MacIntyre’s ethical framework, on how to make possible the recovery of a metaphysical and anthropological desire that transcends natural aging and goes beyond death. We conclude that both human dependence and the virtues that arise naturally when human beings decide to seek the good of their transcendent condition, make it possible to recover the natural desire for salvation through divine and human love.

A nonuniform superconducting loop poses a challenge to statistical mechanics: assuming thermal equilibrium and applying the accepted rules, we obtain that the heat flow does not vanish.

A recent fMRI study by Webb et al. (Cortical networks involved in visual awareness independent of visual attention, Proc Natl Acad Sci U S A 2016;113:13923–28) proposes a new method for finding the neural correlates of awareness by matching atten- tion across awareness conditions. The experimental design, however, seems at odds with known features of attention. We highlight logical and methodological points that are critical when trying to disentangle attention and awareness.

Los fenómenos urbanos son modos concretos de reproducción social y, como toda reproducción, tienen un carácter histórico. En este artículo se defenderá que es posible identificar tres grandes paradigmas históricos en el desarrollo urbano del Occidente moderno —la ciudad, la metrópolis y la postmetrópolis— y que su forma de gobernanza coincide con los tres tipos de poder identificados por Foucault: el soberano, el disciplinar y el biopolítico. Además, se analizará cómo cada una de estas tres dobles configuraciones de la reproducción (...) social genera unos puntos neurálgicos, cuya manipulación produce un impacto sobre el sistema mucho mayor que cualquier otra posible acción, tanto si está orientada al dominio institucional del poder constituido como a la resistencia frente al mismo. El presente trabajo aborda la lógica de funcionamiento de estos tres modelos urbanos, identificando sus respectivos centros neurálgicos como punto de partida desde el que es viable constituir el sujeto político antagónico más efectivo posible en cada uno de ellos.

Social entrepreneurship is usually understood as an economic activity which focuses at social values, goals, and investments that generates surpluses for social entrepreneurs as individuals, groups, and startups who are working for the benefit of communities, instead of strictly focusing mainly at the financial profit, economic values, and the benefit generated for shareholders or owners. Social entrepreneurship combines the production of goods, services, and knowledge in order to achieve both social and economic goals and allow for solidarity building. From a (...) broader perspective, entities that are focused on social entrepreneurship are identified as parts of the social and solidarity economy. These are, for example, social enterprises, cooperatives, mutual organizations, self-help groups, charities, unions, fair trade companies, community enterprises, and time banks. Social innovation is a key element of social entrepreneurship. Social innovation is usually understood as new strategies, concepts, products, services, and organizational forms that allow for the satisfaction of needs. Such innovations are created in particular in the contact areas of various sectors of the social system. For example, these are spaces between the public sector, the private sector, and civil society. These innovations not only allow the solving of problems but also extend possibilities for public action. (shrink)

RESUMEN Este trabajo pretende relacionar dos debates emparentados sobre cómo la lógica y el lenguaje influyen sobre el pensamiento. Existe un eje de discusión en relación a si hay una pluralidad de lógicas o un único sistema lógico como criterio de evaluación para cualquier contexto de razonamiento. En lingüística, el debate surgido a partir de las interpretaciones fuertes y débiles de la hipótesis Sapir-Whorf ha centralizado la discusión en torno al grado de influencia o determinación del lenguaje sobre el pensamiento. (...) Desde perspectivas y marcos teórico-conceptuales diferentes, lógica y lingüística delimitan y problematizan un campo de indagación y reflexión. El artículo, desde una mirada transdisciplinar, pretende dar cuenta y postular vasos comunicantes entre estos debates atendiendo a los matices de cada enfoque, así como proponer una hipótesis propia sobre la problemática planteada. ABSTRACT This paper aims to relate two debates about how logic and language influence thought. There is an axis of discussion about whether there exists a plurality of logic or a single logical system as an evaluation criterion for any reasoning context. In linguistics, the debate arising from the strong and weak interpretations of the Sapir-Whorf hypothesis has centralized the discussion around the degree of influence or determination of language on thought. From different perspectives and theoretical-conceptual frameworks, logic, and linguistics delimit and problematize a field of inquiry and reflection. The article, from a transdisciplinary perspective, intends to account for and postulate communicating vessels between these debates, considering the nuances of each approach. It also seeks to propose its own hypothesis on the problem raised. (shrink)

In this paper, I reject that animal reasoning, negation in particular, necessarily involves the representation of absences, as suggested by Bermúdez (2003, 2006, 2007), since this would still work as a logical negation (unavailable for non-linguistic creatures). False belief, pretense, and communication experiments show that non-human animals (at least some primates) have difficulties representing absent entities or properties. I offer an alternative account resorting to the sub-symbolic similarity judgments proposed by Vigo & Allen (2009) and expectations: animal proto-negation takes place (...) through the incompatibility between an expected and the actual representation. Finally, I propose that the expectation paradigm be extrapolated to other experi-ments in cognitive psychology (both with pre-linguistic children and animals) in order to design fair experiments that test other minds considering their true abilities.

En la obra de Nicol existe una concepción original de biopolítica que difiere de las teorías más conocidas. Parte de una concepción de la humanidad caracterizada por la tensión entre «comunidad histórica» y «especie natural»; y plantea una diferencia sustancial entre el mundo de la cultura-técnica-libertad vs. naturaleza biológica y necesidad. Nicol sostiene que en nuestra era la libertad humana decae, ya que la humanidad se está reduciendo a comportarse como una especie natural en lucha por su supervivencia ante la (...) posibilidad de un colapso civilizatorio. Por ello, formula una concepción de biopolítica que no solo consiste en un mecanismo para imponer control biológico sobre poblaciones humanas, pues descubre una nueva dimensión biopolítica surgida del predominio de la «razón de fuerza mayor», razón sistemática de extrema necesidad, que surge como consecuencia del posible colapso civilizatorio que se extiende globalmente, y que ha sido desencadenada por la expansión del poder tecnológico y la destrucción ecológica. El desenlace de este colapso sería un impensable retroceso de la humanidad al nivel de una especie biológica en lucha por su supervivencia colectiva, con la consecuente pérdida de fines históricos y decisiones libremente elegidas. Se analizan estas tesis críticamente y se evalúa su validez y sus consecuencias teóricas. (shrink)

State sovereignty is often thought to be absolute, unlimited. This paper argues that there is no such a thing as absolute State sovereignty. Indeed, absolute sovereignty is impossible because all sovereignty is necessarily underpinned by its conditions of possibility—i.e. limited sovereignty is the norm, though the nature of the limitations varies. The article consists of two main sections: the concept of sovereignty: this section is focused on some of the limitations the concept of sovereignty itself presents; and a historical account (...) of the notion of sovereignty as it was used in the Ancient Times. The particular focus on early notions of a modern concept such as sovereignty has to do with the fact that this early notion has been anthropomorphised with societal evolution. Therein, the current concept of State sovereignty embraces the same limitations it had in its ancient form as a non-fully developed conceptual idea. The implications of understanding State sovereignty as limited rather than absolute are several, both directly and indirectly. A main immediate consequence is that sovereign States can cooperate together, limit their sovereignty and still be considered sovereign. (shrink)

Clearly in contrast to the sociosymbolic approaches that underlie the positions of Butler or Derrida, this article delves into a materialist and machinic reading of the ontology of Deleuze and Guattari. This ontology is the basis of a posthumanist conception that allows to join political philosophy, technology and biology understood as complex rhizomatic systems. From this point of view, we propose to construct an antagonistic posthumanist politics that is an alternative to the pluriversal ethics defended by Braidotti. We believe that (...) the latter maintains an excessively liberal position that prioritizes inclusion as a new form of consensus in the face of conflict. (shrink)

This paper presents a reading of Metaphysics Z.10–11 according to which both chapters outline two main definienda: forms and material substances or compounds, each of which is governed by its own peculiar constraints. Forms include formal parts alone; furthermore, they are the main definable items and enjoy the strictest possible unity. However, this does not preclude Aristotle from upgrading material compounds to the status of definable items in their own right. Z.10 explains this contention by making the compound’s sensible functional (...) matter dependent on its form. This dependence affords the resulting compound an unusually tight form-matter relationship, strong enough to ensure its definability, despite falling short of the highest kind of unity that only forms display.

Este artículo cuestiona filosóficamente, a partir de las tesis de Günther Anders, el uso masivo de las redes sociales y la forma en que configuran la subjetividad y la intersubjetividad, particularmente en cuanto a los efectos cognitivos sobre la verdad, las creencias y la objetividad.
