Turing's programme, the idea that intelligence can be modelled computationally, is set in the context of a parallel between certain elements from metamathematics and Popper's schema for the evolution of knowledge. The parallel is developed at both the formal level, where it hinges on the recursive structuring of Popper's schema, and at the contentual level, where a few key issues common to both epistemology and metamathematics are briefly discussed. In light of this connection Popper's principle of transference, akin to Turing's (...) belief in the relevance of the theory of computation for modelling psychological functions, is widened into the extended principle of transference. Thus Turing's programme gains a solid epistemological footing. *I am grateful to Claude Lamontagne and Jean-Pierre Delage for their comments on this paper. (shrink)

With the normative demand to attend to social difference and an absence of universal evaluative terms with which to do so, recent theory has increasingly turned to the study of the affective rather than epistemological conditions of ethical encounter. This I call a “dispositional ethics” that construes responsibility as responsiveness. Recent articulations of such an ethics, notably in the most current work of Judith Butler, James Tully, Jade Larissa Schiff, and Ella Myers, highlight its connection to situated practices of concrete (...) bodies-in-relation, but often stop short of developing an account of what such embodied practices might be. Based on interviews with thirteen experts who take the body as their primary vocational and intellectual field and characterize their practice as an art of listening, I distinguish three dimensions of a dispositional ethics in practice and some of the specific strategies available to cultivate the conditions for responsiveness in political life.

Listening appears as elusive as it is crucial to democratic life, particularly in conditions of structural injustice. Dominant groups benefit from histories and habits of inattention and, when enlisted, common responses of denial, defensiveness, and resentment. What lies behind this pervasive and persistent failure to listen to claims of structural injustice by more advantaged groups, and what does this mean for democratic engagement? This paper addresses this question via three interventions: first, it develops a novel account of listening that reveals (...) why listening to claims of structural injustice often proves difficult. Second, it examines how inhabiting positions of relative advantage shapes whether and how people listen to such claims. Finally, it explores the implications these challenges have for the design of democratic processes that seek to engage advantaged groups regarding structural injustice. To develop this account, I draw together current scholarship regarding listening and structural injustice with original fieldwork of recent and current efforts to engage more advantaged communities regarding a specific form of structural injustice: specifically, interviews and observation of the ten organizations across Aotearoa New Zealand most active in efforts to engage communities regarding socio-economic inequality in the country.

Decolonization requires critical attention to settler logics that reinforce settler-colonialism, yet settler communities, as a rule, operate without a collective sense of identity and history. This article, provoked by Māori protocols of encounter, explores the necessity of developing a sense of collective identity as precursor to meeting in settler-Indigenous politics. It argues that the ability, desire, and experience of being unmarked as a social group—apparent in paradigmatic approaches to engaging social difference in settler communities—is at the heart of the particularity (...) of settler group identity and also stands at the heart of countless failures to meet in settler-Indigenous politics. This essay thus seeks to mark the particular ground of this unmarkedness of settler identity in Western philosophies that set being unmarked as both ontology and ideal; the dominance of settler communities in places of settlement; and the willful forgetting of the colonial histories brought about by such dominance.

Long histories and entrenched habits of inattention among advantaged groups mean that even minor challenge and concession can provoke subjective perceptions of victimization. How, in such conditions, might claims of structural injustice break through? Drawing on field work with practitioners across conflict mediation, therapy, education, and performance – four sectors that facilitate listening in fraught contexts yet are undertheorized in politics – this article makes the case that among the most overlooked and powerful resources for cultivating receptivity and responsiveness among (...) advantaged groups are the arts of listening. Practices of engagement across these sectors establish listening as potent rather than passive, given the extent to which it constitutes the field of encounter and shapes what emerges within it, both in terms of expression and, more significantly in this context, receptivity of those to whom one listens. Yet this also means that how one listens is a pivotal consideration – particularly when listening might serve to reinforce and normalize unjustly dominant positions. In contrast to progressive politics’ emphasis on finding more forceful forms of voice and conventional reliance on direct communicative practices, this article explores how specific comedic, theatrical, and embodied tactics can generate ‘oblique forms of listening’ potentially useful to social justice struggles.

With so much attention on the issue of voice in democratic theory, the inverse question of how people come to listen remains a marginal one. Recent scholarship in affect and neuroscience reveals that cognitive and verbal strategies, while privileged in democratic politics, are often insufficient to cultivate the receptivity that constitutes the most basic premise of democratic encounters. This article draws on this scholarship and a recent case of forum theatre to examine the conditions of receptivity and responsiveness, and identify (...) specific strategies that foster such conditions. It argues that the forms of encounter most effective in cultivating receptivity are those that move us via affective intensity within pointedly mediated contexts. It is this constellation of strategies—this strange marriage of immersion and mediation—that enabled this performance to surface latent memory, affect and bias, unsettle entrenched patterns of thought and behaviour, and provide the conditions for revisability. This case makes clear that to lie beyond the domain of cognitive and verbal processes is not to lie beyond potential intervention, and offers insight to how such receptivity might be achieved in political processes more broadly.

Kant prit pour pivot de la révolution copernicienne l'immutabilité d'une table qui portait toute l'autorité du classicisme et révélait les opérations secrètes d'un sensus communis logicus. La logique n'avait pas d'histoire. Après la rupture introduite par la logique mathématique et pour la conjurer, on s'est intéressé à son histoire comme présentant autant de variétés d'une même forme. Mais la forme, terme homonyme entre l'eidos platonicien et la syntaxe moderne, gardait l'écorce sans le fruit, oubliant que l'héritage grec avait fructifié ailleurs, (...) dans les arts et dans les sciences et vivait précisément de ses métamorphoses. Le projet de Platon, accompli par le stoïcisme, donne la mesure de l'héritage athénien. L'épisode ouvert par Frege laissait un tout autre avenir que de choisir entre la formalisation ou le silence. Car la logique mathématique, liée à l'histoire de l'algèbre et de la calculabilité, ménageait la place pour une activité philosophique délivrée à son tour des opérations obscures du sens commun et consciente de ses symbolismes. Ce qui redonne sens aux réformes de l'entendement, opération philosophique essentielle et constante, contre les méthodes supposées régir toutes les manières de la connaissance. Cette autre histoire se trame de Port-Royal, à d'Alembert, Wittgenstein, Cavaillès et Merleau-Ponty. La connaissance s'y trouve servie par la diversité de ses supports, y compris styles et syntaxes, tous inscrits sur le palimpseste des opérations inconscientes qui précèdent toute épistémologie.

In this paper, we will review research done by the Large-Scale Integrated Photonics group at HP Laboratories, and in particular we will discuss applications of optical resonances in dielectric microstructures and nanostructures to future classical and quantum information technologies. Our goal is to scale photonic technologies over the next decade in much the same way as electronics over the past five, thereby establishing a Moore’s Law for optics.

Je resitue tout d'abord la notion d'égalité dans le contexte historique de la société industrielle moderne, afin d'en retracer la genèse. Cette approche vise à introduire le lecteur au problème de la saisie conceptuelle de la notion d'égalité et de la détermination de son contenu. C'est l'occasion de discuter si cette notion peut répondre à une fonction heuristique ou bien si elle n'a qu'un rôle éristique. L'hypothèse développée est qu'une telle notion constitue plutôt une représentation schématique de celle de justice. (...) La vacuité principielle du schème d'égalité a, par ailleurs, toujours pour effet de nous reconduire en définitive à l'examen de sa fonctionnalité opérationnelle.I set up at first the notion of equality within the historical context of modern industrial society, so that its genesis is recalled to mind. This way of approach aims at placing the reader in front of the problem which consists in apprehending conceptually the notion of equality and in determining its content. That gives the opportunity to inquire thereinto, if the considered notion may have an heuristic value or else only an eristic character. The unfolded hypothesis is that such a notion provides rather a schematic depiction for the one of justice. The vacuity in itself of the schema of equality compels moreover to ponder after all its operational functionality everywhere it is applied. (shrink)

In lieu of an abstract, here is a brief excerpt of the content:Reviewed by:The Historiography of Philosophy by Michael FredeClaude PanaccioMichael Frede. The Historiography of Philosophy. Edited by Katerina Ierodiakonou, with a postface by Jonathan Barnes. Oxford: Oxford University Press, 2022. Pp. 256. Hardback, $80.00.From the 1970s until his tragic death in 2007, Michael Frede was one of the most prominent scholars in ancient Greek philosophy, with landmark contributions to the study of Aristotle and of Hellenistic thought in particular. This (...) volume contains his theoretical reflections on the work of historians of philosophy. The main part of the book reproduces with minor corrections the previously unpublished text of the Nellie Wallace Lectures that Frede gave in 1989–90 in Oxford (1–135). Then come three papers that he published on pretty much the same topic between 1987 and 1992 (137–88). Jonathan Barnes's postface, finally, launches an exciting discussion of Frede's proposals by raising a number of questions and critical remarks about them (189–230).Frede's main claim throughout the book is that there is, and should be, a distinctively historical approach to the history of philosophy that has not yet been sufficiently recognized as such in the academic world. This is not to say that he considers more philosophical approaches to be illegitimate. His point is that we have to be clear about the distinction and what it involves in terms of requirements and methods. What Frede calls the "historical history of philosophy" is thus contrasted by him with two varieties of philosophical approaches. One of them he identifies as the "philosophical history of philosophy." It consists in retrospectively studying the past of philosophy as a kind of maturation toward some more recent doctrinal stage, as Aristotle or Hegel saliently did with their respective predecessors. Frede takes this to be "a perfectly intelligible and legitimate, though perhaps not particularly interesting or fruitful, enterprise" (41). Most of the time, he thinks, it would be led by its own philosophical presuppositions to be too selective and to provide a badly distorted picture of past philosophy.Frede is much more sympathetic to the other philosophical approach to the history of philosophy he acknowledges, the one he calls "doxography." This is the study of past philosophers with the aim of finding something of interest in them for ongoing philosophical discussions—a familiar practice, indeed, in the philosophical discipline as we know it. There is an inevitable amount of anachronism in such endeavors, according to Frede, insofar as the commentators will have to reformulate the old views in contemporary terms to a certain extent and to look at them in connection with the questions that are currently debated in the field. But Frede deems this kind of anachronism acceptable as long as sufficient care is taken to correctly identify the views of the past we are interested in and to report them in the best available way. He strongly insists, however, that there are inherent risks of distortion in this approach. This might not be a problem if we are prepared to deal, as philosophers, with views that were not exactly those of the past; but we then run the risk of leaving out something of great philosophical interest, even to us, since "as a rule the philosopher subjected to doxographical treatment was a much better philosopher than the doxographer" (34). If we turn to the past for philosophical inspiration, we should also do it seriously, and this presupposes a historical study of past authors that is pursued for its own sake. [End Page 317]The latter is what Frede is really interested in, and he wants this historical approach to be "as independent as possible from philosophy and not just an ancilla to philosophy" (60). Its practitioners must have a strong philosophical training, of course, in order to understand the views they study and the arguments that were adduced in support of them, but Frede insists that they nevertheless are historians first and foremost: they strive to provide a correct account of "the actual, historical evolution of these views and positions" (14) and of how new doctrines actually grew out of previous ones given the historical context. Insofar as this is what they are doing, historians of... (shrink)

Claude Romano seeks to change all that, to describe precisely what sort of phenomenon an event is and to establish how it can be grasped via a phenomenology.

ArgumentAfter having measured the velocity of the nervous impulse in the 1850s, Helmholtz began doing research on the temporal dimensions of visual perception. Experiments dealing with the velocity of propagation in nerves were carried out occasionally for some fifteen years until their final publication in 1871. Although the temporal dimension of perception seems to have interested Helmholtz less than problems of geometry and space, his experiments on the time of perception were technically rather subtle and seminal, especially compared with experiments (...) performed by his contemporaries, such as Sigmund Exner, William James, Rudolf Hermann Lotze, Ernst Mach, Wilhelm Volkmann, and Wilhelm Wundt. Helmholtz’s conception of the temporal aspects of perception reflects the continuity that holds between psychophysiological research and the Kantian philosophical background. (shrink)

In the latest years of the 6th/12th century, two chains of affiliation of a distinctive kind make their appearance in the Muslim world, in the East on one hand, and in the West on the other: the first is referred to in the sources as silsilat al-muṣāfaḥa, the second as silsilat al-mushābaka. These ‘chains’, mentioned mostly in works pertaining to the genre of prosopographic literature in the largest sense, experienced a broad and rapid expansion throughout the dār al-islām. They are (...) linked to a specific ritual aimed at perpetuating, across generations, a physical contact with the Prophet. Widespread among the ʿulamāʾ, they become conflated with the musalsalāt ḥadīths, or ‘chained traditions’, during the Ottoman era. (shrink)

Novel forms of matter, such as states made of gluons (glueballs), multiquark mesons or baryons and hybrid mesons are predicted by low energy QCD, for which several candidates have recently been identified. Searching for such exotic states of matter and studying their production and decay properties in detail has become a flourishing field at the experimental facilities now available or being built - e.g. BESIII in Beijing, BELLE II at SuperKEKB, GlueX at Jefferson Lab, PANDA at FAIR, J-PARC and in (...) the upgraded LHC experiments, in particular LHCb. A modern primer in the field is required so as to both revive and update the teaching of a new generation of researchers in the field of QCD. These lectures on hadron spectroscopy are intended for Master and PhD students and have been originally developed for a course delivered at the Stefan Meyer Institute of the Austrian Academy of Sciences. They are phenomenologically oriented and intended as complementary material for basic courses in particle and nuclear physics. The book describes the spectra of light and heavy mesons and baryons, and introduces the fundamental properties based on symmetries. Further, it derives multiplet structures, mixing angle, decay coupling constants, magnetic moments of baryons, and predictions for multiquark states and compares these with suitable experimental data. Basic methods of calculating decay angular distributions and determining masses and widths of resonances are also presented. The appendices provide students and newcomers to the field with the necessary background information, and include a set of problems and solutions. (shrink)
