Courtesy of its free energy formulation, the hierarchical predictive processing theory of the brain (PTB) is often claimed to be a grand unifying theory. To test this claim, we examine a central case: activity of mesocorticolimbic dopaminergic (DA) systems. After reviewing the three most prominent hypotheses of DA activity—the anhedonia, incentive salience, and reward prediction error hypotheses—we conclude that the evidence currently vindicates explanatory pluralism. This vindication implies that the grand unifying claims of advocates of PTB are unwarranted. More generally, (...) we suggest that the form of scientific progress in the cognitive sciences is unlikely to be a single overarching grand unifying theory. (shrink)

The free-energy principle states that all systems that minimize their free energy resist a tendency to physical disintegration. Originally proposed to account for perception, learning, and action, the free-energy principle has been applied to the evolution, development, morphology, anatomy and function of the brain, and has been called a postulate, an unfalsifiable principle, a natural law, and an imperative. While it might afford a theoretical foundation for understanding the relationship between environment, life, and mind, its epistemic status is unclear. Also (...) unclear is how the free-energy principle relates to prominent theoretical approaches to life science phenomena, such as organicism and mechanism. This paper clarifies both issues, and identifies limits and prospects for the free-energy principle as a first principle in the life sciences. (shrink)

The role of prefrontal cortex (PFC) in influencing creative thinking has been investigated by many researchers who, while succeeding in proving an effective involvement of PFC, reported suggestive but sometimes conflicting results. In order to better understand the relationships between creative thinking and brain activation in a more specific area of the PFC, we explored the role of dorsolateral PFC (DLPFC). We devised an experimental protocol using transcranial direct-current stimulation (tDCS). The study was based on a 3 (kind of stimulation: (...) anodal vs. cathodal vs. sham) × 2 (priming: divergent vs. convergent) design. Forty-five healthy adults were randomly assigned to one stimulation condition. Participants’ creativity skills were assessed using the Product Improvement subtest from the Torrance Tests of Creative Thinking (TTCT). After 20 min of tDCS stimulation, participants were presented with visual images of common objects. Half of the participants were instructed to visualize themselves using the object in an unusual way (divergent priming), whereas the other half were asked to visualize themselves while using the object in a common way (convergent priming). Priming was aimed at inducing participants to adopt different attitudes toward the creative task. Afterwards, participants were asked to describe all of the possible uses of the objects that were presented. Participants’ physiological activation was recorded using a biofeedback equipment. Results showed a significant effect of anodal stimulation that enhanced creative performance, but only after divergent priming. Participants showed lower skin temperature values after cathodal stimulation, a finding which is coherent with studies reporting that, when a task is not creative or creative thinking is not prompted, people show lower levels of arousal. Differences in individual levels of creativity as assessed by the Product Improvement test were not influential. The involvement of DLPFC in creativity has been supported, presumably in association to shift of attention modulated by priming. (shrink)

Some naturalistic philosophers of mind subscribing to the predictive processing theory of mind have adopted a realist attitude towards the results of Bayesian cognitive science. In this paper, we argue that this realist attitude is unwarranted. The Bayesian research program in cognitive science does not possess special epistemic virtues over alternative approaches for explaining mental phenomena involving uncertainty. In particular, the Bayesian approach is not simpler, more unifying, or more rational than alternatives. It is also contentious that the Bayesian approach (...) is overall better supported by the empirical evidence. So, to develop philosophical theories of mind on the basis of a realist interpretation of results from Bayesian cognitive science is unwarranted. Naturalistic philosophers of mind should instead adopt an anti-realist attitude towards these results and remain agnostic as to whether Bayesian models are true. For continuing on with an exclusive focus and praise of Bayes within debates about the predictive processing theory will impede progress in philosophical understanding of scientific practice in computational cognitive science as well as of the architecture of the mind.

According to the free energy principle, life is an “inevitable and emergent property of any random dynamical system at non-equilibrium steady state that possesses a Markov blanket” :20130475, 2013). Formulating a principle for the life sciences in terms of concepts from statistical physics, such as random dynamical system, non-equilibrium steady state and ergodicity, places substantial constraints on the theoretical and empirical study of biological systems. Thus far, however, the physics foundations of the free energy principle have received hardly any attention. (...) Here, we start to fill this gap and analyse some of the challenges raised by applications of statistical physics for modelling biological targets. Based on our analysis, we conclude that model-building grounded in the free energy principle exacerbates a trade-off between generality and realism, because of a fundamental mismatch between its physics assumptions and the properties of actual biological targets.

This article deals mainly with problems of cultural/transcultural translation between the Quechua and Spanish cultures, analysing these on the basis of some ideas by Juri Lotman and Peeter Torop. The process of translation implies considering the Quechua semiosphere’s internal borders as well as the external borders related to the cultures that existed at the time of Tahuantin Suyo, and all changes that have come from the Spanish conquest of Latin America. In the case of the Quechua culture, the problems are (...) numerous and conflicting in several dimensions. First of all, Quechua is an agglutinating language that creates problems for translation into a flexional language such as Spanish. Secondly, and more importantly, there exists a mythopoetical model of the world that has been built in this culture, which does not use concepts of rational logic, but poetic images integrated into mythical thinking: it represents a different cognitive pattern. Thirdly, the presence of the logic of the concrete in Quechua culture, articulated with the mythopoetical model, makes translation from Western abstract formal logic difficult. Reflections on these issues provide new analytical possibilities. (shrink)

Summary The anniversary of the death of Pietro Tacchini (1838?1905), one of the pioneers of solar physics in Italy, is commemorared by this account of his major creation, the Società degli Spettroscopisti Italiani (1871). Established to promote cooperation among solar spectroscopists engaged in the study of the solar chromosphere, it was the first scientific Society devoted to spectroscopy and its astronomical applications. Its journal, the Memorie, collected most of the important works on solar physics by Angelo Secchi SJ (1818?1878), Tacchini (...) himself, and many other protagonists of the newly born astrophysics. A brief history of the Society and its development draws on many previously unexploited archival sources, in order to show its role in raising astrophysics to the status of a scientific discipline, in the context of the astronomical research of that time in Italy and abroad, especially in the USA.

This paper builds on John Dewey’s views on interactions to suggest pathways for enriching the study of philosophy. Along with the notions of body-mind and organism-environment transactions, interactions are part of a philosophical project with transformative implications for education as well. The first part of the paper will contextualize Dewey’s discussion of interactions with regard to his philosophy of experience and democratic theory. The second one will propose two criteria with regard to enriching philosophical training in ways that engage the (...) mind and the body - increasing sociocultural awareness and generating integrative learning experiences – and will add a few examples of how the study of philosophy could benefit from applying an interactionist perspective.

El artículo propone un análisis del tratamiento kantiano de la �Tercera antinomia de la razón pura� (en la que se examina la posibilidad de conciliar la libertad trascendental con el determinismo natural), a fin de mostrar el carácter infundado de aquella interpretación que sostiene que la resolución crítica de dicha antinomia supone un desplazamiento respecto de los términos cosmológicos en los que el conflicto es planteado originariamente. A través de un análisis pormenorizado de las fuentes, procuraremos establecer que el conflicto (...) analizado en la �Tercera antinomia� no es de carácter exclusivamente cosmológico, sino que constituye asimismo �y en igual medida� un conflicto práctico y, en segundo lugar, que la solución crítica no es desarrollada en términos exclusivamente prácticos, sino que involucra asimismo aspectos directamente vinculados con la cuestión cosmológica inicialmente formulada.

Background: The Self-Regulation of Eating Behavior Questionnaire is an economical way of assessing an individual's self-regulatory abilities regarding eating behavior. Such scales are needed in the German population; therefore, the purpose of the present study was the translation and validation of a German version of the SREBQ.Method: First, we conducted a pilot study after the translation procedure. Second, we assessed the final scale in a representative sample of the German population and its underlying factor structure. Further, we tested for measurement (...) invariance and evaluated the SREBQ's associations with related scales to explore convergent and discriminant validity. Finally, we considered differences in SREBQ based on sociodemographic variables and provided derived reference scores.Results: Factor analysis revealed deficiencies in the original model. Thus, we shortened the scale based on statistical considerations and the adapted version showed improved fit in Confirmatory Factor Analysis and reliability. We also found evidence for partial strict invariance, which means the measure is equivalent for the tested groups of age and gender. Item and scale psychometric properties of the shortened version were satisfactory. In terms of diagnostic validity, it was shown that individuals with higher body mass index have worse self-regulation of eating behavior than those with lower.Conclusion: In sum, the SREBQ evidenced good validity and reliability and is suitable for application in medical, psychological, and nutritional research.

In our daily life we develop habits that, being constantly practiced, become part of who we are. Two areas in which we develop habits are the evaluation of sources of food, and the evaluation of sources of happiness. It is my contention that the habits developed in those areas could affect one another. Thus, acquiring good habits in one area is of utmost importance to develop the other one. Conversely, if we develop the bad habit of picky eating this will (...) have as one of its outcomes the development of a bad habit that restricts our openness to rmding avenues for happiness. In order to show how the two habits affect one another, I will use Aristotle's theory of habit as developed in his Nicomachean Ethics. (shrink)

A popular view in philosophy of science contends that scientific reasoning is objective to the extent that the appraisal of scientific hypotheses is not influenced by moral, political, economic, or social values, but only by the available evidence. A large body of results in the psychology of motivated-reasoning has put pressure on the empirical adequacy of this view. The present study extends this body of results by providing direct evidence that the moral offensiveness of a scientific hypothesis biases explanatory judgment (...) along several dimensions, even when prior credence in the hypothesis is controlled for. Furthermore, it is shown that this bias is insensitive to an economic incentive to be accurate in the evaluation of the evidence. These results contribute to call into question the attainability of the ideal of a value-free science. (shrink)

A widely shared view in the cognitive sciences is that discovering and assessing explanations of cognitive phenomena whose production involves uncertainty should be done in a Bayesian framework. One assumption supporting this modelling choice is that Bayes provides the best approach for representing uncertainty. However, it is unclear that Bayes possesses special epistemic virtues over alternative modelling frameworks, since a systematic comparison has yet to be attempted. Currently, it is then premature to assert that cognitive phenomena involving uncertainty are best (...) explained within the Bayesian framework. As a forewarning, progress in cognitive science may be hindered if too many scientists continue to focus their efforts on Bayesian modelling, which risks to monopolize scientific resources that may be better allocated to alternative approaches.

Resumen: Este trabajo examina la posición que adopta Kant en la polémica del spinozismo, la cual involucró a importantes figuras de la Ilustración alemana en un debate acerca de los alcances y límites de la razón. Con la publicación del texto Was heisst: Sich im Denken orientiren?, Kant rechaza tanto la posición de Jacobi -quien declara que la razón es incapaz de arribar a una demostración de la existencia de Dios y proclama la necesidad de un "salto a la fe"- (...) como la posición de Mendelssohn, quien confía en las posibilidades de la razón para alcanzar tal demostración. A través de una concepción de la razón como facultad crítica y autónoma, Kant toma una posición mediadora en el debate, y establece los alcances y límites de la razón, fundamentalmente en lo que atañe a la representación de Dios como ser originario. El concepto de razón esbozado en el escrito de 1786 deja entrever la insoslayable dimensión política ínsita en la noción kantiana de publicidad. El modo en que Kant concibe allí la conexión entre razón, crítica, publicidad y política trasciende los márgenes de dicha polémica e introduce cuestiones fundamentales sobre las condiciones político-jurídicas que se requieren para el ejercicio autónomo del pensamiento. Sin embargo, y pese a la radicalidad de los planteamientos kantianos, la naturalización racionalista de la creencia religiosa supone un límite de la filosofía crítica que exige revisarse a la luz de criterios actuales.: This paper analyzes the position taken by Kant in the controversy of Spinozism, which engaged many important thinkers of the German Enlightenment in a debate on the scope and limits of reason. With the publication of Was heisst: Sich im Denken orientiren?, Kant takes part in the debate and rejects both the position adopted by Jacobi -who regards reason as incapable of reaching a demonstration of God's existence and thus proclaims the necessity of a "leap of faith"-, and Mendelssohn's position, who trusts in the possibilities of reason to reach such a demonstration. By means of a conception of reason as a critical and autonomous faculty, Kant attempts to go beyond both positions, and sets the scope and limits of reason in regard to the representation of God as the originating being. The concept of reason developed within the framework of the critical project exhibits its unavoidable political dimension in the text of 1786. Kant establishes there a connection between reason, critique, publicity, and politics that goes beyond the margins of the controversy and addresses fundamental issues regarding the political and juridical conditions required for an autonomous exercise of reason. However, despite the radical character of Kant's proposals, the rationalistic naturalization of religious belief represents a limit to his critical philosophy, and should be revised by the lights of current criteria.

How should the information that a proposition p is a mystery impact your credence in p? To answer this question, we first provide a taxonomy of mysteries; then, we develop a test to distinguish two types of mysteries. When faced with mysteries of the first type, rational epistemic agents should lower their credence in p upon learning that p is a mystery. The same information should not impact agents’ credence in p, when they face mysteries of the second type. Our (...) account of mystery complements existing explications of abduction. We illustrate its significance by examining the mystery of consciousness. (shrink)

RESUMENEn este escrito proponemos examinar en qué sentido la interpretación epistémica de la distinción crítica fenómeno/cosa en sí resulta compatible con la interpretación de la cosa en sí como entidad real. Atendiendo a este objetivo, se intentará mostrar que dicha interpretación epistémica, lejos de reducir la cosa en sí a un mero concepto heurístico, conduce a una consideración de la misma como entidad efectivamente existente (más allá de las dificultades que obviamente supone la aplicación de las categorías de realidad y (...) existencia a aquello que, por definición, jamás puede ser dado como objeto de experiencia).PALABRAS CLAVEFENÓMENO, COSA EN SÍ, PERSPECTIVA, REALIDADABSTRACTIn this paper I shall analyze in what sense the Epistemic Interpretation of the critical distinction between appearances and things in themselves is compatible with an interpretation of the thing in itself as a real entity. I will try to show that the epistemic interpretation, far from reducing the thing in itself to a mere heuristic concept, leads to a consideration of the thing in itself as an existing entity (notwithstanding the difficulties which are obviously involved in the application of the categories of reality and existence to what can never be given as an object of experience).KEYWORDSAPPEARANCE, THING IN ITSELF, PERSPECTIVE, REALITY.

The ethnographic description of story-telling and narrative transmission of cultural facts is an aspect of Locke & Bogin's (L&B's) article that should be amplified. Innate shared gene patrimony is biased by the kinship structure of particular societies and interacts with the transmission of narratives. Trance experiences are another interesting aspect of verbal and agonistic “performances.”.

Durante os séculos XVI e XVII a filosofia, a ciência e a arte começam a se separar, principalmente por conta da consolidação da ciência e de sua produção de conhecimento racional, baseada em princípios lógicos e matemáticos, buscando compreender e dominar a natureza de modo objetivo, enquanto a arte irá se ocupar da sensibilidade, utilizando de discursos e meios subjetivos de levantar questionamentos, tendo como base as faculdades do juízo e, por fim, a filosofia irá promover uma reflexão mais profunda (...) e uma análise mais precisa das produções de conhecimento das duas áreas, não se separando, mas partindo delas. Assim sendo, o presente trabalho buscou oferecer uma proposa didática e interdisciplinar para o ensino médio normal ou integrado, a fim de abarcar os conhecimentos produzidos pela ciência, arte e filosofia, tendo como aporte teórico as discussões desenvolvidas pela Teoria Crítica. Para tanto, apresentou uma discussão teórica a respeito das inter-relações existentes entre as grandes áreas; e para o desenvolvimento da proposta didática trabalhou com diferentes materiais didáticos como a filosofia da Escola de Frankfurt, as obras do artista Ai Weiwei, entre outros. Como resultados, pretende-se ilustrar as possibilidades de trabalhar com diferentes saberes de forma interdisciplinar e integradora. (shrink)

Las observaciones que Kant formula en sus obras críticas acerca de la existencia de la cosa en sí han dado lugar a importantes objeciones y agudas discusiones entre los intérpretes.

What is the relationship between the concepts of the predictive processing theory of brain functioning and the everyday concepts with which people conduct and explain their mental lives? To answer this question, we focus on predictive processing explanations of mental disorder that appeal to false inference. After distinguishing two concepts of false inference, we survey four ways of understanding the relationship between explanations of mental phenomena at the personal and sub-personal level. We then argue that if predictive processing accurately accounts (...) for psychological and socio-cultural dynamics, then personal and sub-personal concepts must display a looping relationship that can impact the nature of at least some mental phenomena. In particular, explaining the phenomenon of delusion in terms of the sub-personal concept of false inference should change the nature of delusional experiences themselves. (shrink)

There continues to be significant confusion about the goals, scope, and nature of modelling practice in neuroeconomics. This article aims to dispel some such confusion by using one of the most recent critiques of neuroeconomic modelling as a foil. The article argues for two claims. First, currently, for at least some economic model of choice behaviour, the benefits derivable from neurally informing an economic model do not involve special tractability costs. Second, modelling in neuroeconomics is best understood within Marr’s three-level (...) of analysis framework and in light of a co-evolutionary research ideology. The first claim is established by elucidating the relationship between the tractability of a model, its descriptive accuracy, and its number of variables. The second claim relies on an explanation of what it can take to neurally inform an economic model of choice behaviour. 1 Introduction2 Neurally Informed Models of Choice: A Case Study2.1 A case study on risk-sensitive choice2.1.1 Target and modelling framework2.1.2 Research question and hypotheses2.1.3 Competitive models of risk-sensitive behaviour2.1.4 Model-based fMRI: from economics to brains and back2.2 Neurally informed modelling3 Tractability: When Does Size Matter?4 Neural Integration and the Co-evolutionary Research Ideology5 Conclusion.

Letheby’s "Philosophy of Psychedelics" relies on Predictive Processing to try and find unifying explanations relevant to understanding how serotonergic psychedelics work in psychiatric therapy, what subjective experiences are associated with their use and whether such experiences are epistemically defective. But if Predictive Processing lacks genuinely explanatory unifying power, Letheby’s account of psychedelic therapy risks being unwarranted. In this commentary, I motivate this worry and sketch an alternative interpretation of psychedelic therapy within the Reinforcement Learning framework.

In lieu of an abstract, here is a brief excerpt of the content:Feminist Studies 47, no. 1. © 2021 by Feminist Studies, Inc. 201 Ileana Nachescu Censoring Anglogynophobia: Reconsidering the Disappearance of the National Alliance of Black Feminists Black women’s activism in the 1970s has often been located in the fissures between the civil rights movement, women’s liberation movement, and Black nationalism—a form of “interstitial feminism,” in the words of Kimberly Springer.1 Providing crucial interventions to disrupt male supremacy and (...) sexism within Black organizations as well as racism and homophobia within feminist organizations, Black feminist politics modeled a “vanguard center” whose liberation signaled the liberation of all.2 The Combahee River Collective’s “Black Feminist Statement” (1977), which has become a classic in women’s, gender, and sexuality studies curricula, encapsulates the power of this transformative image. The Combahee River Collective was not the only Black feminist group active in the second half of the 1970s, of course. The Third World Women’s Alliance (TWWA), founded in 1969, had a vibrant presence on both the East Coast and the West Coast throughout this decade. The National Black Feminist Organization (NBFO), active between 1973 and 1975, mobilized Black women around the country and gave the impetus for the formation of several local chapters. After NBFO ended, the 1. Kimberly Springer, “The Interstitial Politics of Black Feminist Organizations,” Meridians 1, no. 2 (Spring 2001): 156. 2.

In October 1977, NABF’s national conference, “A Meeting of the Minds,” attracted more than two hundred African American women to Chicago for two days in order to discuss their experiences, listen to speakers, and develop an agenda to address the most pressing issues of the day. To this day, the long list of resolutions passed at this conference constitutes the most comprehensive set of political, economic, and cultural demands collectively devised by African American women. Yet, more than four decades later, NABF has disappeared from public consciousness, remembered only by a small group of feminist historians. The erasure of NABF from women’s history and Black history is a puzzle—in part because the organization excelled at the kinds of activities that leave visible traces. In an interview with Kimberly Springer, Combahee River Collective founder Barbara Smith noted that “People who write get far more visibility than those who don’t.”3 But NABF Executive Director Brenda Eichelberger published many essays in regional and national periodicals documenting diverse initiatives by Black feminists in the 1970s. Furthermore, unlike many feminist organizations that did not record their operations or whose records have been lost, NABF intentionally gathered and preserved rich archival materials.4 Using materials from the National Alliance of Black Feminists archives, I suggest that NABF defies many received views about Black feminist activism, and this defiance makes attention to NABF all the more vital to the history of US feminism. By examining NABF’s original theorization of “Anglogynophobia,” Black women’s distrust of and animosity toward white women, I advance a much darker explanation for the 3.

This paper brings together results from the philosophy and the psychology of explanation to argue that there are multiple concepts of explanation in human psychology. Specifically, it is shown that pluralism about explanation coheres with the multiplicity of models of explanation available in the philosophy of science, and it is supported by evidence from the psychology of explanatory judgment. Focusing on the case of a norm of explanatory power, the paper concludes by responding to the worry that if there is (...) a plurality of concepts of explanation, one will not be able to normatively evaluate what counts as good explanation.

Despite the impressive amount of financial resources invested in carrying out large-scale brain simulations, it is controversial what the payoffs are of pursuing this project. The present paper argues that in some cases, from designing, building, and running a large-scale neural simulation, scientists acquire useful knowledge about the computational performance of the simulating system, rather than about the neurobiological system represented in the simulation. What this means, why it is not a trivial lesson, and how it advances the literature on (...) the epistemology of computer simulation are the three preoccupations addressed by the paper. (shrink)
