This article advertises a new account of computational implementation. According to the resemblance account, implementation is a matter of resembling a computational architecture. The resemblance account departs from previous theories by denying that computational architectures are exhausted by their formal, mathematical features. Instead, they are taken to be permeated with causality, spatiotemporality, and other nonmathematical features. I argue that this approach comports well with computer scientific practice and offers a novel response to so-called triviality arguments.

The received view of computation is methodologically bifurcated: it offers different accounts of computation in the mathematical and physical cases. But little in the way of argument has been given for this approach. This article rectifies the situation by arguing that the alternative, a unified account, is untenable. Furthermore, once these issues are brought into sharper relief we can see that work remains to be done to illuminate the relationship between physical and mathematical computation.

A skeptical worry known as ‘the indeterminacy of computation’ animates much recent philosophical reflection on the computational identity of physical systems. On the one hand, computational explanation seems to require that physical computing systems fall under a single, unique computational description at a time. On the other, if a physical system falls under any computational description, it seems to fall under many simultaneously. Absent some principled reason to take just one of these descriptions in particular as relevant for computational explanation, (...) widespread failure of computational explanation would appear to follow. This paper advances a new solution to the indeterminacy of computation. Very roughly, I argue that the computational identity of a physical system is determinate relative to a contextually specified way of regarding that system computationally—known as a labelling scheme. When a system simultaneously implements multiple computations, it does so relative to different labelling schemes. But relative to a fixed labelling scheme, a physical system has a unique computational identity. I argue that this relativistic conception of computational identity vindicates computational explanation in the face of simultaneous implementation. (shrink)

What is computational explanation? Many accounts treat it as a kind of causal explanation. I argue against two more specific versions of this view, corresponding to two popular treatments of causal explanation. The first holds that computational explanation is mechanistic, while the second holds that it is interventionist. However, both overlook an important class of computational explanations, which I call limitative explanations. Limitative explanations explain why certain problems cannot be solved computationally, either in principle or in practice. I argue that (...) limitative explanations are not plausibly understood in either mechanistic or interventionist terms. One upshot of this argument is that there are causal and non-causal kinds of computational explanation. I close the paper by suggesting that both are grounded in the notion of computational implementation. (shrink)

This paper examines the question of why consumers engage in ethical consumption. The authors draw on self-affirmation theory to propose that the choice of an ethical product serves a self-restorative function. Four experiments provide support for this assertion: a self-threat increases consumers’ choice of an ethical option, even when the alternative choice is objectively superior in quantity (Study 1) and product quality (Study 2). Further, restoring self-esteem through positive feedback eliminates this increase in ethical choice (Studies 2 and 3). As (...) an additional test of the robustness of our results, a final study examined the effect of self-threat on choice in a field setting (Study 4). The findings indicate that ethical purchases are not just altruistic. They hold purposeful individual value and can help in the self-restorative process. Implications for managers making decisions regarding investment in ethical product features are discussed. (shrink)

Can scientific evidence outstretch what scientists have mentally entertained, or could ever entertain? This article focuses on the plausibility and consequences of an affirmative answer in a special case. Specifically, it discusses how we may treat automated scientific data-gathering systems—especially AI systems used to make predictions or to generate novel theories—from the point of view of confirmation theory. It uses AlphaFold2 as a case study.

Résumé Cet article se propose d’envisager le signe iconique à l’aune du modèle néosaussurien du signe et de la sémiosis qui se dégage des Écrits de linguistique générale. Après avoir exposé ce modèle à partir des propositions que François Rastier tire des textes autographes de Saussure, cette contribution transpose le cadre à la description du signe iconique, en réinterrogeant certains éléments de la conceptualisation que donne le Groupe µ de ce type d’énoncé visuel. Une brève analyse de la toile Le (...) retour à la nature de Magritte permet d’illustrer et de valider la transposition théorique du modèle néosaussurien du signe et de la sémiosis. Cette démarche ouvre la possibilité de procéder à l’interprétation des images selon la théorie morphosémiotique développée par la sémantique de Rastier. (shrink)

The author wonders how his investigation — based on a lack — could find a place in the changeful concept of literature. He has recourse to the notion of experience of nothingness whose import for Michaux he studies with the help of a few examples. One of these — Michaux writing on Rimbaud — leads him to observe that a poetics of motion sustains this experience in its quest for an elsewhere. The issues inherent in Michaux’s work are those of (...) a literature built on its own impossibility, called upon to articulate ineffable silence. Are such considerations and the proper theological stance compatible? (shrink)

After a generous introduction to the subject, essays follow on transcendence and spirituality from a multidisciplinary and multifaith perspective: a focus on Abrahamic, Oriental, and African religions, a study of transcendence in Nazism, etc.

This note discusses the account of physical computation offered in Part II of Primiero’s On the Foundations of Computing. Although there is much to find attractive about the account, I argue that the account is obscure at certain crucial junctures and that it does not supply a wholly satisfactory account of miscomputation. I close by considering whether the engineering foundation of computing requires a theory of physical computation in the first place, suggesting tentatively that it does not.

On the heels of colonization, missionization, capitalistic development and globalization, contemporary members of the Navajo Nation are daily inundated with a variety of tensions associated with the `politics of identity'. Based on recent consultations with Navajo of all walks of life about how they accommodate biomedical technologies within their religiously and medically pluralistic world, this article demonstrates how Navajo people anchor relatedness within their sacred space through the use of language, detached bodily substances or parts, and ritualized practices. These speech (...) acts and practices, which are routinely done in the simultaneous process of person-and-place building, are also done to intentionally reinforce fragile social relations or perhaps more importantly to re-embed disrupted social relations through the process of emplacement. Using ethnographic information about Navajo views on the bioeconomy of excorporated bodily substances, this article considers how Navajo people specifically use decisions regarding blood donation or transfusion to strengthen individual and collective identity.

Nombreux sont les romans québécois qui, depuis une quinzaine d’années, construisent la figure du personnage à partir d’éléments empruntés à la vie de Jésus. Les romanciers ne cherchent pas à renouveler une quelconque vision de la vie du Christ, mais ils prennent prétexte de l’intertexte christique pour traiter de questions qui les préoccupent. Dans ce contexte, cet article fait voir plus précisément comment Pierre Samson, dans Le Messie de Belém, et Sylvain Trudel, dans Du mercure sous la langue, développent (...) la question du rapport de l’homme à l’amour. Tandis que le rapport amoureux est fondateur d’un nouvel espoir messianique chez Pierre Samson, il apparaît radicalement voué à l’inexistence chez Sylvain Trudel. There are many Quebec novels that, for 40 some years, have been constructing characters based on elements drawn from the life of Jesus. The novelists are not seeking to renew some ordinary vision of Christ, but use the Christ-like intertext in order to deal with questions that concern them. In this context, this article shows exactly how Pierre Samson, in Le Messie de Belém, and Sylvain Trudel, in Du mercure sous la langue, develop the question of the relation between the human being and love. While the love-relationship founds a new messianic home for Pierre Samson, it appears doomed to nonexistence for Sylvain Trudel. (shrink)
