In 1672, inspired by the wave theory of Ignace Gaston Pardies, Christiaan Huygens made his first attempt to explain the sine law of refraction, but in 1673 he abandoned his plans owing to difficulties concerning double refraction. Huygens was able to explain double refraction on 6 August 1677 after his discoveries of the axis of symmetry of the crystal and of ‘Huygens's principle’. On 6 August 1679, he wrote: ‘I have found the confirmation of my theory of light (...) and of refraction’, and then described an ‘experimentum crucis’ to decide between his theory and a rival hypothesis. A study of caustics may have led Huygens to the discovery of ‘Huygens's principle’. (shrink)

Although Auguste Comte is conventionally acknowledged as one of the founders of sociology and as a key representative of positivism, few new editions of his writings have been published in the English language in this century. He has become virtually dissociated from the history of modern positivism and the most recent debates about it. Gertrud Lenzer maintains that the work of Comte is, for better or for worse, essential to an understanding of the modern period of positivism. This collection provides (...) new access to the work of Comte and gives practitioners of various disciplines the possibility of reassessing concepts that were first introduced in Comte's writings. Today much of the ordinary business of academic disciplines is conducted under the assumption that the realm of science is essentially separate from the realms of politics and science. A close reading of Comte will reveal how deeply such current ideas and theories were originally embedded in a particular political context. One of his central methodological principles was that the theory of society had to be removed from the arena of political practice precisely in order to control that practice by means of these same sciences. It is in Comte's work that the reader will be able to observe how the forces of social and political reaction began to be powerfully organized to combat the critical forces in its own and later eras. Auguste Comte and Positivism will be of importance to the work of philosophers, sociologists, political theorists, and historians. (shrink)

Temps et sujet : Sujet du temps? Temps du sujet? De quel temps peut-on parler? Où sont les temps? Comment les sciences sociales et plus particulièrement la psychologie peuvent-elles s'emparer des temps subjectifs? Peut-on parler d'une construction psychique de la perception du temps? L'Institut de Psychologie et Sciences Sociales d'Angers (IPSA) a constitué un groupe de recherche sur le thème du temps du sujet, de sa perception du temps et de son appréhension de la durée. Approches psychanalytique, anthropologique, philosophique se (...) mélangent, se coupent et se recoupent. Suite à des discussions contradictoires sur plus d'une année, ce sont neuf contributions qui tentent de définir ce que pour elles peut être le temps. Par ailleurs vous trouverez un index des différentes figures du temps et de ses signifiants dans l'œuvre de Lacan. (shrink)

Orthodoxy holds that the difference between weakness of will and compulsion is a matter of the resistibility of an agent's effective motivation, which makes control-based views of agency especially well equipped to distinguish blameworthy weak-willed acts from non-blameworthy compulsive acts. I defend an alternative view that the difference between weakness and compulsion instead lies in the fact that agents would upon reflection give some conative weight to acting on their weak-willed desires for some aim other than to extinguish them, but (...) not to their compulsive desires. This view allows identificationist theorists of moral responsibility to explain why weak-willed actions, but not compulsive actions, are attributable to agents such that they can, in theory, be praised or blamed for them. After motivating and presenting the view in detail, I show how it has unique resources for explaining the ethics of managing one's compulsions. (shrink)

O cuidado espiritual é um componente essencial para a qualidade dos serviços em cuidados paliativos (CP). Este artigo apresenta a revisão da literatura empírica sobre cuidadores(as) espirituais que atuam nos Cuidados Paliativos. O método utilizado foi a revisão integrativa, com levantamento nas bases Periódicos CAPES, PsycARTICLES e PubMed. Após exame das 643 publicações encontradas, 54 estudos foram selecionados para análise, categorizados em quatro grandes temas: “identidade dos(as) cuidadores(as) espirituais”, “capacitação dos(as) cuidadores(as) espirituais”, “atuação dos(as) cuidadores(as) espirituais” e “impactos da atuação (...) dos(as) cuidadores(as) espirituais”. O suporte espiritual é fator vital para o bem-estar e a qualidade de vida no fim da vida, sendo que o cuidado paliativo transdisciplinar é fundamental para prover atendimento às necessidades espirituais e psicossociais, o que será facilitado pela adoção de métodos padronizados. Currículos de treinamento e ferramentas de avaliação específicos permitem a avaliação sistemática nos resultados dos pacientes, familiares e clínicos. Considerando a importância da religiosidade no contexto cultural brasileiro, o aprofundamento do tema do cuidado espiritual é de grande relevância para profissionais que trabalham em CP. A Bioética e a Teologia são chamadas a contribuir com estudos nessa área a fim de que o cuidado espiritual possa ser efetivamente integrado nas equipes de CP. (shrink)

Network concepts are omnipresent in contemporary diagnoses, management practices, social science methods and theories. Instigating a critical analysis of network concepts, this article explores the sources and relevance of networks in Foucault’s social theory. I argue that via Foucault we can trace network concepts back to cybernetics, a research programme that initiated a shift from ‘being’ to ‘doing’ and developed a new theory of regulation based on connectivity and codes, communication and circulation. This insight contributes to two debates: Firstly, it (...) highlights a neglected influence on Foucault’s theory that travelled from cybernetics via structuralism and Canguilhem into his concept of power. Secondly, it suggests that network society and governance are neither a product of neoliberalism nor of technological artefacts, such as the Internet. They rather resulted from a distinct tradition of cybernetically inspired theories and practices. (shrink)

This article investigates the causal efficacy of social properties, which faces the following puzzle. First, for both intuitive and scientific reasons, it seems social properties have causal import. But, second, social properties are also characteristically extrinsic: to have some social property depends, in typical cases, on what one’s society is like around them. And, third, there is good reason to doubt that extrinsic properties make a genuine causal contribution. After elaborating on these three claims, I defend the following resolution to (...) the puzzle: social causation occurs at the level at which social properties are intrinsic. (shrink)

As COVID-19 spread, clinicians warned of mental illness epidemics within the coronavirus pandemic. Funding for digital mental health is surging and researchers are calling for widespread adoption to address the mental health sequalae of COVID-19. -/- We consider whether these technologies improve mental health outcomes and whether they exacerbate existing health inequalities laid bare by the pandemic. We argue the evidence for efficacy is weak and the likelihood of increasing inequalities is high. -/- First, we review recent trends in digital (...) mental health. Next, we turn to the clinical literature to show that many technologies proposed as a response to COVID-19 are unlikely to improve outcomes. Then, we argue that even evidence-based technologies run the risk of increasing health disparities. We conclude by suggesting that policymakers should not allocate limited resources to the development of many digital mental health tools and should focus instead on evidence-based solutions to address mental health inequalities.

In this chapter I argue that choosing to live forever comes with the threat of an especially pernicious kind of boredom. However, it may be theoretically possible to circumvent it by finding ways to pursue an infinite number of projects consistent with one’s personality, taking on endlessly pursuable endlessly interesting projects, or by rekindling old projects once you’ve forgotten about them. However, each of these possibilities is contingent upon having certain traits that you are likely not currently in a good (...) position to assess. I therefore argue that no one is in a good position to be confident about her prospects for living forever. (shrink)

Western democracies experience profound conflicts that induce concerns about polarization and social cohesion. Yet although conflicts are a core feature of democracies, the forms, functions, and dynamics of democratic conflicts have rarely been subject of political theory. This paper aims at furthering our understanding of democratic conflicts. It analyzes the theory of conflict in Mouffe's agonistic pluralism, confronts it with sociological conflict theory, and presents concrete points of departure for a more comprehensive theory of democratic conflicts. The paper, thus, contributes (...) to two lines of research: (1) Regarding agonistic theories, the paper shows that agonistic pluralism fails to provide a convincing theory of conflict since it underestimates the mechanisms and effects of conflict dynamics (e.g. intergroup cohesion, intragroup conflict, domination, and escalation) and fails to account for the variety of conflict interactions. Proponents of agonistic pluralism should therefore invest more into clarifying their core concept. (2) For a general account of democratic conflicts, the paper proposes to pursue interdisciplinary research on the cognitive concepts shaping conflict interactions, the linked practices of conflict regulation, and the processual dynamics of conflicts.

How do groups of people persist through time? Groups can change their members, locations, and structure. In this paper, I present puzzles of persistence applied to social groups. I first argue that four-dimensional theories better explain the context sensitivity of how groups persist. I then exploit two unique features of the social to argue for the stage theory of group persistence in particular. First, fusion and fission cases actually happen to social groups, and so cannot be marginalized as “pathological.” Second, (...) it is implausible that groups spatially coincide pre-fission. This means that theories that depend on pre-fission spatial coincidence, such as some endurance theories and the worm theory, cannot explain fission cases. All things considered, the stage theory offers the best explanation of how groups persist. (shrink)

This paper advances a new agentially undemanding account of the conditions of attributability, the Minimal Approval account, and argues that it has a number of advantages over traditional Deep Self theories, including the way in which it handles agents with conditions like addiction, Tourette syndrome, and misophonia. It is argued that in order for an agent to be attributionally responsible, the mental process that leads to her action must dispose her to be such that she would, upon reflec-tion, approve to (...) some minimal degree of being moved to action by the motive on which she in fact acts.

Preview: /Review: Andrea J. Pitts and Mark William Westmoreland, eds. Beyond Bergson: Examining Race and Colonialism Through the Writings of Henri Bergson, 255 pages./ Among Bergson’s contributions to philosophical and empirical investigations; such as those centered on freedom, memory, and evolution; exists in the form of his last book, The Two Sources of Morality and Religion. It is interesting because, as many readers of Bergson have remarked, it does not seem to fit well, primarily in method, with his other endeavors (...) in the pursuit of philosophical exploration and elaboration. Having been mentored by a philosopher who holds this position, I have long shied away from the text that represents Bergson’s last concerted philosophical effort of inquiry. Meanwhile, having been intrigued by the possibility of a more just world and compelled by a desire to serve such an end, I was interested in envisioning what a Bergsonian philosophy of social justice, revolution, or morality would contain. Early on in my readings of Bergson, I felt the seeming applicability of Bergson’s method of intuition to moral and social questions. Over the years, I have devoted significant time to thinking through durational investigations of intensity to problems of social justice. While I have made some inroads to accomplishing this goal, I feel the journey has just begun for me. It was in this context that I was excited at the prospect of this book, and it is this book that has helped me to appreciate some of the ways that Bergson’s philosophy could be adapted to thinking through moral and social questions. To be clear, much work has been done in the way of expounding political or moral philosophies in which Bergson’s thought might be interpreted as a prelude. My reluctance to embrace Two Sources has been a self-imposed hindrance to my engaging in those extra-Bergsonian works for fear of running against the current of Bergson’s earlier texts. My reticence is intended to be taken as neither a slight of Bergson’s Two Sources nor a discounting of those who find inspiration in that work. (shrink)

This paper brings together two erstwhile distinct strands of philosophical inquiry: the extended mind hypothesis and the situationist challenge to virtue theory. According to proponents of the extended mind hypothesis, the vehicles of at least some mental states (beliefs, desires, emotions) are not located solely within the confines of the nervous system (central or peripheral) or even the skin of the agent whose states they are. When external props, tools, and other systems are suitably integrated into the functional apparatus of (...) the agent, they are partial bearers of her cognitions, motivations, memories, and so on. According to proponents of the situationist challenge to virtue theory, dispositions located solely within the confines of the nervous system (central or peripheral) or even the skin of the agent to whom they are attributed typically do not meet the normative standards associated with either virtue or vice (moral, epistemic, or otherwise) because they are too susceptible to moderating external variables, such as mood modulators, ambient sensibilia, and social expectation signaling. We here draw on both of these literatures to formulate two novel views – the embedded and extended character hypotheses – according to which the vehicles of not just mental states but longer-lasting, wider-ranging, and normatively-evaluable agentic dispositions are sometimes located partially beyond the confines of the agent’s skin.

We argue that the interaction of biased media coverage and widespread employment of the recognition heuristic can produce epistemic injustices. First, we explain the recognition heuristic as studied by Gerd Gigerenzer and colleagues, highlighting how some of its components are largely external to, and outside the control of, the cognitive agent. We then connect the recognition heuristic with recent work on the hypotheses of embedded, extended, and scaffolded cognition, arguing that the recognition heuristic is best understood as an instance of (...) scaffolded cognition. In section three, we consider the double-edged sword of cognitive scaffolding. On the one hand, scaffolds can reduce the internal processing demands on cognitive agents while increasing their access to information. On the other hand, the use of scaffolding leaves cognitive agents increasingly vulnerable to forming false beliefs or failing to form beliefs at all about particular topics. With respect to the recognition heuristic, agents rely on third parties (such as the media) to report not just what’s true but also what’s important or valuable. This makes cognitive agents relying on these third parties vulnerable to two erroneous influences: 1) because they don’t recognize something, it isn’t important or valuable, and 2) because they do recognize something, it is important or valuable. Call the latter the Kardashian Inference and the former the Darfur Inference. In section four, we use Fricker’s (2007) concept of epistemic injustice to characterize the nature and harm of these false inferences, with special emphasis on the Darfur Inference. In section five, we use data-mining and an empirical study to show how Gigerenzer’s population estimation task is liable to produce Darfur Inferences. We conclude with some speculative remarks on more important Darfur Inferences, and how to avoid them by scaffolding better. One primary way to accomplish this it to shift the burden of embodying the virtue of epistemic justice from the hearer or consumer of media to the media themselves. (shrink)
