In this paper we present the results of a simulation study of credence developments in groups of communicating Bayesian agents, as they update their beliefs about a given proposition p. Based on the empirical literature, one would assume that these groups of rational agents would converge on a view over time, or at least that they would not polarize. This paper presents and discusses surprising evidence that this is not true. Our simulation study shows that these groups of Bayesian agents (...) show group polarization behavior under a broad range of circumstances. This is, we think, an unexpected result, that raises deeper questions about whether the kind of polarization in question is irrational. If one accepts Bayesian agency as the hallmark of epistemic rationality, then one should infer that the polarization we find is also rational. On the other hand, if we are inclined to think that there is something epistemically irrational about group polarization, then something must be off in the model employed in our simulation study. We discuss several possible interfering factors, including how epistemic trust is defined in the model. Ultimately, we propose that the notion of Bayesian agency is missing something in general, namely the ability to respond to higher-order evidence. (shrink)

According to Vera Moser, the first professorship of healing pedagogy, Heilpädagogik at the University of Zürich in 1931, established pedagogy of the disabled as an academic discipline. Through the definition of the smallest common denominator for all disabilities, which Heinrich Hanselmann called “weakness of the soul,” a connecting element of “imbecility, deaf-mutism, blindness, neglect and idiocy” was established. Under Nazi rule, school pedagogy advanced to völkisch, nationalist special pedagogy, shifting from the category of “innate imbecility” to a broader concept of (...) disability. As an outcome of these programs and policies, 300,000 people with disabilities were killed as a part of the “T4 Aktion.” Within just a few decades after World War II, special pedagogy expanded its sphere of influence through professionalization and institutionalization in West and East Germany and across Europe. This paper explores how special pedagogy aligned itself with the Nazi regime’s discourse and policy on eugenics and race hygiene, leading to the murder and mass sterilization of “disabled” children and adults. It probes questions regarding the extent to which the professionalization of special pedagogy has drawn from the Nazi-era terminology of the deficient and foreign to legitimate the contemporary migrant bias in German and Austrian special pedagogical care.

What is the relationship between the philosophical concept of the “autonomy of art” and the cultural policy-notion of “artistic freedom”? This article seeks to answer this question by taking the Swedish governmental report This Is How Free Art Is (Så fri är konsten 2021) and its reception in the Swedish main stream media as an emblematic example and by reading it symptomatically. Firstly, it traces the critical history of “artistic freedom” and the interrelated term “arm’s length distance”, primarily in the (...) context of Great Britain. Secondly, it critically reconstructs the concept of the “autonomy of art” in the history of Western philosophy by making a critique of a fetishized notion of art’s autonomy in the name of l’art pour l’art. The main argument is that the idea about art’s autonomy, on which the Swedish report leans, resembles such philosophical and art historical idea of art’s autonomy. The claim is also that such an understanding of art does not tie up, either philosophically or historically, with the arm’s length principle, since they ultimately rely on different conceptions of art’s freedom.

Over the last century, there have been considerable variations in the frequency of use and types of diagrams used in mathematical publications. In order to track these changes, we developed a method enabling large-scale quantitative analysis of mathematical publications to investigate the number and types of diagrams published in three leading mathematical journals in the period from 1885 to 2015. The results show that diagrams were relatively common at the beginning of the period under investigation. However, beginning in 1910, they (...) were almost completely unused for about four decades before reappearing in the 1950s. The diagrams from the 1950s, however, were of a different type than those used earlier in the century. We see this change in publication practice as a clear indication that the formalist ideology has influenced mathematicians’ choice of representations. Although this could be seen as a minor stylistic aspect of mathematics, we argue that mathematicians’ representational practice is deeply connected to their cognitive practice and to the contentual development of the discipline. These changes in publication style therefore indicate more fundamental changes in the period under consideration. (shrink)

Against common misconceptions of Kant as a philosopher who neglects the emotional aspects of moral life, I show that he actually considers our emotional dispositions to be valuable tools for perfecting ourselves morally. ;I show not only that it is incumbent on us to cultivate morally beneficial emotions, but also how we can do it. Building on Kant's vague hints about what the process involves, I argue that cultivating a given feeling requires, above all, sharpening one's judgment about it, one's (...) sensitivity to its nature and to the shape it takes in one's own character in order to make responsible decisions about whether to act on the feeling and when one does choose to act on it, to express it in a way which harmonizes with one's sense of moral integrity. ;I begin with an argument showing that on Kant's mature moral theory, it is our duty to cultivate feelings which help us form a virtuous disposition. I then discuss particular feelings which are especially important in this regard. I begin with the feeling of respect for the moral law and show that it constitutes the motive of duty. Kant's "pure" moral motive--the motive of duty--is thus actually a feeling which is grounded in a rational grasp of the moral law. I then consider feelings associated with our duties toward ourselves and with our duties toward others and raise the question of how cultivated feelings figure in the virtuous character and also in relation to good willing and to morally worthy action. I show that certain "moral" feelings can become part of the motive of duty itself and so can serve as motives to morally worthy action. (shrink)

Nietzsche wrote The Gay Science, which he later described as 'perhaps my most personal book', when he was at the height of his intellectual powers, and the reader will find in it an extensive and sophisticated treatment of the philosophical themes and views which were most central to Nietzsche's own thought and which have been most influential on later thinkers. These include the death of God, the problem of nihilism, the role of truth, falsity and the will-to-truth in human life, (...) the doctrine of the eternal recurrence, and the question of the proper attitude to adopt toward human suffering and toward human achievement. This volume presents the work in a new translation by Josefine Nauckhoff, with an introduction by Bernard Williams that elucidates the work's main themes and discusses their continuing philosophical importance.

Postural instability marks a prevalent symptom of Parkinson’s disease. It often manifests in increased body sway, which is commonly assessed by tracking the Center of Pressure. Yet, in terms of postural control, the body’s Center of Mass, and not CoP is what is regulated in a gravitational field. The aim of this study was to explore the effect of early- to mid-stage PD on these measures of postural control in response to unpredictable visual perturbations. We investigated three cohorts: 18 patients (...) with early to mid-stage PD [Hoehn & Yahr stage ; 1.94 ± 0.70]; a group of 15 age-matched controls ; and a group of 12 young healthy adults. Participants stood on a force plate to track their CoP, while the movement of their entire body was recorded with a video-based motion tracking system to monitor their CoM. A moving room paradigm was applied through a head-mounted virtual reality headset. The stimulus consisted of a virtual tunnel that stretched in the anterior-posterior direction which either remained static or moved back and forth in an unpredictable fashion.We found differences in mean sway amplitude and mean velocities of CoP and CoM between the groups under both conditions, with higher MSA of CoP and CoM for PD and higher mean velocities of both variables for PD and ECT when compared with YCT. Visual perturbation increased mean CoP velocity in all groups but did not have effects on mean CoM velocity or MSA. While being significantly lower for the young adults, the net effect of visual perturbation on mean CoP velocity was similar between patients with PD and age-matched controls. There was no effect of the visual perturbation on mean CoM velocity for any of the groups.Our simultaneous assessment of CoP and CoM revealed that postural control is reflected differently in CoM and CoP. As the motion of CoM remained mostly unaffected, all groups successfully counteracted the perturbation and maintained their balance. Higher CoP velocity for PD and ECT revealed increased corrective motion needed to achieve this, which however was similar in both groups. Thus, our results suggest increased effort, expressed in CoP velocity, to be an effect of age rather than disease in earlier stages of PD. (shrink)

The review gives an introductory description of the successive development of data patterns based on comparisons between hearing-impaired and normal hearing participants’ speech understanding skills, later prompting the formulation of the Ease of Language Understanding model. The model builds on the interaction between an input buffer and three memory systems: working memory, semantic long-term memory, and episodic long-term memory. RAMBPHO input may either match or mismatch multimodal SLTM representations. Given a match, lexical access is accomplished rapidly and implicitly within approximately (...) 100–400 ms. Given a mismatch, the prediction is that WM is engaged explicitly to repair the meaning of the input – in interaction with SLTM and ELTM – taking seconds rather than milliseconds. The multimodal and multilevel nature of representations held in WM and LTM are at the center of the review, being integral parts of the prediction and postdiction components of language understanding. Finally, some hypotheses based on a selective use-disuse of memory systems mechanism are described in relation to mild cognitive impairment and dementia. Alternative speech perception and WM models are evaluated, and recent developments and generalisations, ELU model tests, and boundaries are discussed. (shrink)

Mammalian mitochondrial DNA (mtDNA) replication and repair have been studied intensively for the last 50 years. Although recently advances in elucidating the molecular mechanisms of mtDNA maintenance and the proteins involved in these have been made, there are disturbing gaps between the existing theoretical models and experimental observations. Conflicting data and hypotheses exist about the role of RNA and ribonucleotides in mtDNA replication, but also about the priming of replication and the formation of pathological rearrangements. In the presented review, we (...) have attempted to match these loose ends and draft consensus where it can be found, while identifying outstanding issues for future research. (shrink)
