Why does symbolic communication in humans develop primarily in an oral medium, and how do theories of language origin explain this? Non-human primates, despite their ability to learn and use symbolic signs, do not develop symbols as in oral language. This partly owes to the lack of a direct cortico-motoneuron control of vocalizations in these species compared to humans. Yet such modality-related factors that can impinge on the rise of symbolic language are interpreted differently in two types of evolutionary storylines. (...) 1) Some theories posit that symbolic language originated in a gestural modality, as in “sign languages”. However, this overlooks work on emerging sign and spoken language showing that gestures and speech shape signs differently. 2) In modality-dependent theories, some emphasize the role of iconic sounds, though these lack the efficiency of arbitrary symbols. Other theorists suggest that ontogenesis serves to identify human-specific mechanisms underlying an evolutionary shift from pitch varying to orally-modulated vocalizations (babble). This shift creates numerous oral features that can support efficient symbolic associations. We illustrate this principle using a sound-picture association task with 40 learners who hear words in an unfamiliar language (Mandarin) with and without a filtering of oral features. Symbolic associations arise more rapidly and accurately for sounds containing oral features compared to sounds bearing only pitch features, an effect also reported in experiments with infants. The results imply that, beyond a competence to learn and use symbols, the rise of symbolic language rests on the types of signs that a modality of expression affords. (shrink)

A positive answer to a question of M. van Lambalgen and D. Zambella whether there exist nonrecursive sets that are low for the class of random sets is obtained. Here a set A is low for the class RAND of random sets if RAND = RAND A.

In recent years the study of well-being has attracted considerable attention, fostering hope that the scientific community will ultimately succeed in discovering its very nature, thereby emulating successful scientific projects in other disciplines. However, there have been recurring worries about how to measure and define well-being. In this context, Hersch (Br J Philos Sci 73:1045–1065, 2022) has recently argued that we could progressively alleviate these worries through an iterative dialogue between theory and measurement, by seeing them as stemming from a (...) coordination problem. In this article, I argue that the concept of well-being fails to meet the prerequisites for Hersch’s approach. If the latter is the best defense of the capacity of science to uncover the nature of well-being, it follows that the science of well-being should probably relinquish this ambition. (shrink)

L'hédonisme axiologique a une longue histoire en philosophie. Pourtant, il garde une mauvaise réputation qui lui vaut d’être parfois écarté sans ménagement de la discussion philosophique. Cet article se propose de défendre l'hédonisme axiologique en exposant les principaux arguments en sa faveur et en répondant aux principales critiques et confusions dont il fait l'objet. Une attention particulière sera portée aux arguments établissant la spécificité du plaisir et du déplaisir par rapport à toutes les autres choses — amitié, savoir, justice, etc. (...) — dont on pourrait argumenter la valeur finale.While axiological hedonism has a long history in philosophy, it also has a bad reputation, which has led to it being discarded without proper examination of its plausibility. In this article, I defend axiological hedonism by presenting the main arguments in its favour as well as the criticisms and confusions to which it has been subjected. I pay special attention to the arguments that hint at the specificity of pleasure and displeasure in comparison with other things — friendship, knowledge, justice, etc. — that might be argued to have final value.

This competitively awarded opportunity is open to persons fluent in English, from graduate students to senior scholars, with or without academic appointment, whose scholarship advances knowledge about the ethical, legal, and social implications of health and biotechnologies.3 When we found ourselves on the shores of Lake Leman with the gift of time, we began opening up to each other in unexpected, compelling ways. Whatever our vantage point in the hierarchy of the university system, we discovered that there was remarkable overlap in our experiences as women in academia. When we began writing, our authoring team was composed of two graduate students, four faculty members at the assistant professor rank, and one full professor, residing in Canada, the Netherlands, Romania, the United Kingdom, and the United States. Our plural subject position led us to underexplored and imaginative responses to broader social issues, which we share in this article as the “Brocher Foundation Feminist Collective.” We analyze our experiences from our standpoint as women health researchers laboring in the academy. Our similarities and differences were exciting entry points for discussion and analysis: we are all of eastern or western European descent. We have different countries of birth, mother tongues, ages, disciplinary training and career trajectories, relationships to chronic illness and disability, marital status, and experiences with parenthood. We bring the troubles and contradictions we experience as academics into conversation with each other. We seek to productively illustrate and emphasize that the tensions we see around us, and also feel within us, arise as a result of how the academic system is organized, produced, and sustained across time, place, and space.

Immigration medicine and the work carried out by Panel Physicians within the Canadian immigration system give rise to ethically troublesome practices and consequences. In this analysis in three parts, we explore the context of the immigration medical examination, characterize the observed and potential burdens and harms for immigrant and refugee applicants with HIV, and critically assess the possibilities for transforming immigration medical practices and policy to reduce inequities. We use the Code of Ethics of the Canadian Medical Association and the (...) Medical Ethics Manual of the World Medical Association to analyse six practices that fail to meet ethical expectations. This analysis opens up new lines of inquiry into the medico-administrative practices regulating immigration to Canada. It also extends knowledge about the functioning of immigration medical policy and the collection and uses of HIV-related health information. We argue that to reduce burdens and harms to prospective immigrants and refugees to Canada with HIV, changes must occur in how Citizenship and Immigration Canada asks Panel Physicians to work with these applicants. This argument is empirically informed by institutional ethnographic research results of the Canadian immigration system and its treatment of applicants with HIV. (shrink)

La fonction utopique que l'œuvre de Theodor W. Adorno attribue à la littérature dessine l'horizon d’une « langue sans terre », au-delà de la « dialectique de la raison » et de l’autodestruction de la Raison.

We show that there is a low T-upper bound for the class of K-trivial sets, namely those which are weak from the point of view of algorithmic randomness. This result is a special case of a more general characterization of ideals in $\Delta _2^0 $ T-degrees for which there is a low T-upper bound.

The paper describes the context and the origin of a particular debate that concerns the evolution of phenotypic plasticity. In 1965, British biologist A. D. Bradshaw proposed a widely cited model intended to explain the evolution of norms of reaction, based on his studies of plant populations. Bradshaw’s model went beyond the notion of the “adaptive norm of reaction” discussed before him by Dobzhansky and Schmalhausen by suggesting that “plasticity” the ability of a phenotype to be modified by the environment (...) should be genetically determined. To prove Bradshaw’s hypothesis, it became necessary for some authors to identify the pressures exerted by natural selection on phenotypic plasticity in particular traits, and thus to model its evolution. In this paper, I contrast two different views, based on quantitative genetic models, proposed in the mid-1980s: Russell Lande and Sara Via’s conception of phenotypic plasticity, which assumes that the evolution of plasticity is linked to the evolution of the plastic trait itself, and Samuel Scheiner and Richard Lyman’s view, which assumes that the evolution of plasticity is independent from the evolution of the trait. I show how the origin of this specific debate, and different assumptions about the evolution of phenotypic plasticity, depended on Bradshaw’s definition of plasticity and the context of quantitative genetics.

In 1956, in his Principles of Embryology, Conrad Hal Waddington explained that the word “epigenetics” should be used to translate and update Wilhelm Roux’ German notion of “Entwicklungsmechanik” to qualify the studies focusing on the mechanisms of development. When Waddington mentioned it in 1956, the notion of epigenetics was not yet popular, as it would become from the 1980s. However, Waddington referred first to the notion in the late 1930s. While his late allusion clearly reveals that Waddington readily associated the (...) notion of epigenetics with the developmental process, in the contemporary uses of the notion this developmental connotation seems to have disappeared. The advent and success of molecular biology have probably contributed to focusing biologists’ attention on the “genetic” or the “non-genetic” over the “developmental”. In the present paper, I first examine the links that exist, in Waddington’s work, between the classical notion of epigenesis in embryology and those of epigenetics that Waddington proposed to connect, and even synthesize, data both from embryology and genetics. Second, I show that Waddington’s own view of epigenetics has changed over time and I analyze how these changes appear through his many representations of the relationships between genetic signals and developmental processes.

This is an introduction to a collection of articles on the conceptual history of epigenesis, from Aristotle to Harvey, Cavendish, Kant and Erasmus Darwin, moving into nineteenth-century biology with Wolff, Blumenbach and His, and onto the twentieth century and current issues, with Waddington and epigenetics. The purpose of the topical collection is to emphasize how epigenesis marks the point of intersection of a theory of biological development and a theory of active matter. We also wish to show that the concept (...) of epigenesis existed prior to biological theorization and that it continues to permeate thinking about development in recent biological debates. (shrink)

Demuth tests generalize Martin-Löf tests in that one can exchange the m-th component a computably bounded number of times. A set fails a Demuth test if Z is in infinitely many final versions of the Gm. If we only allow Demuth tests such that GmGm+1 for each m, we have weak Demuth randomness.We show that a weakly Demuth random set can be high and , yet not superhigh. Next, any c.e. set Turing below a Demuth random set is strongly jump-traceable.We (...) also prove a basis theorem for non-empty classes P. It extends the Jockusch–Soare basis theorem that some member of P is computably dominated. We use the result to show that some weakly 2-random set does not compute a 2-fixed point free function.

Kuera, A., On relative randomness, Annals of Pure and Applied Logic 63 61–67. It is the aim of the paper to answer a question raised by M. van Lambalgen and D. Zambella whether there can be a nonrecursive set A having the property that there is a set B such that B is 1-random relative to A and simultaneously A is recursive in B. We give apositive answer to this question as well as further information about relative randomness.

Algorithmic decision making is used in an increasing number of fields. Letting automated processes take decisions raises the question of their accountability. In the field of computational journalism, the algorithmic accountability framework proposed by Diakopoulos formalizes this challenge by considering algorithms as objects of human creation, with the goal of revealing the intent embedded into their implementation. A consequence of this definition is that ensuring accountability essentially boils down to a transparency question: given the appropriate reverse-engineering tools, it should be (...) feasible to extract design criteria and to identify intentional biases. General limitations of this transparency ideal have been discussed by Ananny and Crawford :973–989, 2018). We further focus on its technical limitations. We show that even if reverse-engineering concludes that the criteria embedded into an algorithm correspond to its publicized intent, it may be that adversarial behaviors make the algorithm deviate from its expected operation. We illustrate this issue with an automated news recommendation system, and show how the classification algorithms used in such systems can be fooled with hard-to-notice modifications of the articles to classify. We therefore suggest that robustness against adversarial behaviors should be taken into account in the definition of algorithmic accountability, to better capture the risks inherent to algorithmic decision making. We finally discuss the various challenges that this new technical limitation raises for journalism practice. (shrink)

One of the main objections against effective altruism is the so-called institutional critique, according to which the EA movement neglects interventions that affect large-scale institutions. Alexander Dietz has recently put forward an interesting version of this critique, based on a theoretical problem affecting act-utilitarianism, which he deems as potentially conclusive against effective altruism. In this article I argue that his critique is not as promising as it seems. I then go on to propose another version of the institutional critique. In (...) contrast to Dietz's version, it targets not the core principles of effective altruism but rather some important methodological assumptions made in EA research, namely diminishing marginal returns and low-hanging fruits. One key conclusion is that it may be time for critics of effective altruism to shift their attention from the theoretical core principles of effective altruism towards the methodological tools actually employed in practice by the EA movement.

Our world suffers. Some people suffer more than others. Since the first part of 2020, ours is justly described as a time of uncertainty, threat, and upheaval. In this article, we offer reflections threaded narratively, told from the specificity of our societal contexts in Iran, Canada, and Australia. What might we learn in the present and anticipated future from people living chronically within conditions of uncertainty and immobility and also those experiencing uncertainty and immobility for the first time? We argue (...) that reflexive comparative analysis bridging social and visual analysis, anchored in embodied conditions of such people, offers a way to learn from responses to COVID-19 while also being an exercise in ethical research practice. This reflection builds on and extends from our scholarly collaborations that have been ongoing since 2015. Our title recognizes this specific virus as stealthy. Importantly, our choice of words identifies resident Iranians—whose experiences were the original impetuses for this paper, and whose lives provide its empirical basis —as equally steely. (shrink)

The heterogeneity problem, which stems from the alleged difficulty of finding out what all pleasant experiences have in common, is largely considered as a substantial issue in the philosophy of pleasure, one that is usually taken as the starting point for theorizing about the essence of pleasure. The goal of this paper is to move the focus away from the heterogeneity problem and toward an alternative approach to pleasure. To do this, I first show that, although the approach stemming from (...) the heterogeneity problem has led to an interesting discussion about the essence of pleasure, it has usually endorsed an introspectionist methodology and other problematic assumptions that have led to doubtful results. I thus propose a natural-kind approach to pleasure, which seeks to determine what, if any, the natural kind of pleasure would consist in. This approach broadens the investigation of pleasure by enabling the use of a larger range of methodological tools, thus opening new promising directions for research. (shrink)

Revelation, or the view that the essence of phenomenal properties is presented to us, is as intuitively attractive as it is controversial. It is notably at the core of defences of anti-physicalism. I propose in this paper a new argument against Revelation. It is usually accepted that low-level sensory phenomenal properties, like phenomenal red, loudness or brightness, stand in relation of similarity and quantity. Furthermore, these similarity and quantitative relations are taken to be internal, that is, to be fixed by (...) what their relata are. I argue that, under some plausible additional premises, no account of what grounds these relations in the essence of their relata is consistent with Revelation, at least if we take common phenomenological descriptions for granted. As a result, the plausibility of Revelation is undermined. One might however resist this conclusion by weakening the epistemic relation postulated between subjects and their phenomenal properties.

The concept of plasticity has always been present in the history of developmental biology, both within the theory of epigenesis and within morphogenesis studies. However this tradition relies also upon a genetic conception of plasticity. Founded upon the concepts of ‘‘phenotypic plasticity’’ and ‘‘reaction norm,’’ this genetic conception focuses on the array of possible phenotypic change in relation to diversified environments. Another concept of plasticity can be found in recent publications by some developmental biologists (Gilbert, West-Eberhard). I argue that these (...) authors adopt a ‘‘broad conception of plasticity’’ that is closely related to a notion of development as something that is ongoing throughout an organism’s lifecycle, and has no clear-cut boundaries. However, I suggest that given a narrow conception of plasticity, one can define temporal boundaries for development that are linked to specific features of the morphological process, which are different from behavioral and physiological processes.

Antonin Artaud was a poet, theorist, philosopher, essayist, playwright, actor and director, and one of the 20th century’s most important theoreticians of drama. His theory of the ‘Theatre of Cruelty’ has influenced playwrights as diverse as Beckett, Genet, Albee and Gelber. Magic was always a central concept for Artaud, and in nearly all his writing it is given the most positive force, as something capable of healing the rift between words and things, culture and life. But during his nine (...) years of incarceration in mental asylums, magic seemed to lose its illuminating transformative power and to become demonic and persecutory. Artaud entered the realm of spectres and vampires which he believed were sucking the vitality from his mind and body. Artaud later filled twelve little exercise books with an account of his struggles to escape this physical, psychological and artistic hell. The first eleven books are filled with fragments of writing and extraordinary sketches of totemic figures, pierced bodies and enigmatic machines. Two months before his death, he took a twelfth exercise book and wrote a remarkable, incantatory text, 50 Drawings to Murder Magic. It was the last thing he wrote. (shrink)

Osvald Demuth studied constructive analysis from the viewpoint of the Russian school of constructive mathematics. In the course of his work he introduced various notions of effective null set which, when phrased in classical language, yield a number of major algorithmic randomness notions. In addition, he proved several results connecting constructive analysis and randomness that were rediscovered only much later.In this paper, we trace the path that took Demuth from his constructivist roots to his deep and innovative work on the (...) interactions between constructive analysis, algorithmic randomness, and computability theory. We will focus specifically on Demuth’s work on the differentiability of Markov computable functions and his study of constructive versions of the Denjoy alternative, Demuth’s independent discovery of the main notions of algorithmic randomness, as well as the development of Demuth randomness, and the interactions of truth-table reducibility, algorithmic randomness, and semigenericity in Demuth’s work.

ABSTRACT Polemical terms constitute a special category of polysemous terms. Like all polysemous terms, their use evidences a plurality of conventionalised senses that are felt to be related to one another and, possibly, to a highly abstract core meaning. However, in contrast with ordinary polysemous terms such as rubbish or mouth, polemical terms have something ‘polemical’ about what counts as their primary sense, i.e. the one which is the most faithful to the ‘concept’ they express and to the ‘topic’ they (...) pick out. This poses a challenge for theories that take speakers’ monosemic intuitions seriously and endorse the externalist thesis that it is speakers’ external environment that anchors word meaning in a univocal way. I consider Schroeter and Schroeter’s ‘connectedness model’, which offers an externalist dissociation between ‘concepts’ and the possibly diverging criteria used by speakers. I argue that the model can be adapted to tackle the problem of polemical terms, but only insofar as the assumption of alignment between externalistic concepts and lexical meanings is dropped. I submit that polemical terms do have an abstract core meaning, but of a more impressionistic than conceptual nature. (shrink)

The context of economic globalization has contributed to the emergence of a new form of social action which has spread into the economic sphere in the form of the new social economic movements. The emblematic figure of this new generation of social movements is fair trade, which influences the economy towards political or social ends. Having emerged from multiple alternative trade practices, fair trade has gradually become institutionalized since the professionalization of World Shops, the arrival of fair trade products in (...) the food industry, and the establishment of an official "fair trade" label. With the strength that this institutionalization has generated, fair trade can now be considered a real trade system that questions, as much as it renews, the traditional economic system. In parallel, this transformation has exacerbated the tensions within the movement, which can be characterized as a clash between a "radical, militant" pole and a "softer, more commercial" one. However, it is not the actual institutionalization of fair trade which is being debated among fair trade actors on either side of the fence, but rather the challenges inherent in finding an economic institutionalization acceptable to social economic movements. Therefore the institutionalization process of fair trade should not be seen as mere degradation of social action, but rather as typical of the institutionalization process of new social economic movements. If we need to worry about the highjacking and alteration of the fair trade movement by the dominant economic system, the opposite is no less likely, as new social economic movements contribute to an ethical restructuring of markets.
