There is currently no consensus regarding what measures are most valid to demonstrate perceptual processing without awareness. Likewise, whether conscious perception and unconscious processing rely on independent mechanisms or lie on a continuum remains a matter of debate. Here, we addressed these issues by comparing the time courses of subjective reports, objective discrimination performance and response priming during meta-contrast masking, under similar attentional demands. We found these to be strikingly similar, suggesting that conscious perception and unconscious processing cannot be dissociated (...) by their time course. Our results also demonstrate that unconscious processing, indexed by response priming, occurs, and that objective discrimination performance indexes the same conscious processes as subjective visibility reports. Finally, our results underscore the role of attention by showing that how much attention the stimulus receives relative to the mask, rather than whether processing is measured by conscious discrimination or by priming, determines the time course of meta-contrast masking.

Since its 1980s coining by Richard Falk, the ‘Grotian Moment’ concept has garnered popularity in international law discourse, denoting a rapid, paradigm-shifting development in international law. This concept builds upon a prevalent recollection of two past events as such paradigm-shifts. The first is, obviously, the ‘original’ Grotian Moment, anointing Grotius as the Father of International Law, mainly for publishing, in 1625, his ground-breaking treatise, De Jure Belli ac Pacis, which is said to had brought about a momentous paradigm-shift that gave (...) rise to modern (statist and secular), or even the first-ever-effective, international law. The second event is the post-ww2 Nuremberg international trial. Presumably, from its mid-seventeenth-century birth to Nuremberg, international law was starkly statist, and so individuals had generally not been its subjects. This, among other things, meant that international criminal law (icl) was not acceptable. Nuremberg is, therefore, celebrated as the first-ever international criminal tribunal, as icl’s birthplace and even more generally as the turning-point in international law’s attitude towards the individual. Simply put, Nuremberg is considered the prototype of a modern Grotian Moment. However, this paper shows that neither 1625 nor 1945 were truly Grotian Moments (their significance notwithstanding) and present’s likely causes for those myths. The paper further reveals that these myths, as well as the current embrace of the ‘Grotian Moment’ concept, are all manifestations of a larger, understudied phenomenon: that internationalists, evermore obsessed with perceiving themselves as cutting-edge, too often satisfy that fix by erasing the past.

The paper defends the thesis that institutional virtue is properly modeled as a ‘‘consensual’’ property, along the lines of the Lehrer–Wagner model of consensus (LWC). In a first step, I argue that institutional virtue is not exhausted by duty-fulfilling, since institutions, contrary to natural individuals, are designed to fulfill duties. To avoid the charge of vacuity, virtue, if attributed to institutions, must be able to motivate supererogatory action. In a second step, I argue against dis- continuity of institutional virtue with (...) individual virtue. Two main arguments for discontinuity of collective properties display serious shortcomings when applied to virtues of institutions. Given that motivation for supererogatory action is neither inferred from statutory duties nor accommodates a right of reprobation, modeling institutional virtue on collective rationality or explaining it in terms of joint com-mitment both prove problematic. In a third step, I argue that LWC has the explanatory potential to account for institutional virtue. Due to its main features,iteration and evaluation, it provides a non-trivial analysis of continuity and thereby satisfies basic constraints on the notion of genuine institutional virtue. (shrink)

With a few yet increasing number of exceptions, the cognitive sciences enthusiastically endorsed the idea that there are basic facial expressions of emotions that are created by specific configurations of facial muscles. We review evidence that suggests an inherent role for context in emotion perception. Context does not merely change emotion perception at the edges; it leads to radical categorical changes. The reviewed findings suggest that configurations of facial muscles are inherently ambiguous, and they call for a different approach towards (...) the understanding of facial expressions of emotions. Prices of sticking with the modal view, and advantages of an expanded view, are succinctly reviewed. (shrink)

The contributions gathered in this volume present the state of the art in key areas of current social ontology. They focus on the role of collective intentional states in creating social facts, and on the nature of intentional properties of groups that allow characterizing them as responsible agents, or perhaps even as persons. Many of the essays are inspired by contemporary action theory, emotion theory, and theories of collective intentionality. Another group of essays revisits early phenomenological approaches to social ontology (...) and accounts of sociality that draw on the Hegelian idea of recognition. This volume is organized into three parts. First, the volume discusses themes highlighted in John Searle's work and addresses questions concerning the relation between intentions and the deontic powers of institutions, the role of disagreement, and the nature of collective intentionality. Next, the book focuses on joint and collective emotions and mutual recognition, and then goes on to explore the scope and limits of group agency, or group personhood, especially the capacity for responsible agency. The variety of philosophical traditions mirrored in this collection provides readers with a rich and multifaceted survey of present research in social ontology. It will help readers deepen their understanding of three interrelated and core topics in social ontology: the constitution and structure of institutions, the role of shared evaluative attitudes, and the nature and role of group agents.

The present article focuses on the case of the 2012 hunger-strike of Palestinian prisoners in Israeli jails. We analyze the ethical dilemma involved in the way the Israeli medical community reacted to these hunger-strikes and the question of force feeding within the context of the fundamental dual-loyalty structure inherent in the Israeli Prison Services—system. We argue that the liberal perspective that focuses the discussion on the dilemma between the principle of individual autonomy and the sanctity of life tends to be (...) oblivious to the asymmetrical relation of power that characterizes the prison system and to the socio-political context in which hunger-strikes take place. Emphasizing hunger-strikes as political acts implies that health practitioners’ conducts cannot be analyzed only through the prism of clinical medical ethics. It requires a public health ethics’ approach, an approach that understands health in the context of the complex relationship between society, state, organizations, communities and individuals. The authors are both academics and volunteers in Physicians for Human Rights—Israel thus our analysis is based both on sociological and public health ethics principles and on the continuous work and advocacy for the right to health of prisoners.

An amplitude controllable hyperjerk system is constructed for chaos producing by introducing a nonlinear factor of memristor. In this case, the amplitude control is realized from a single coefficient in the memristor. The hyperjerk system has a line of equilibria and also shows extreme multistability indicated by the initial value-associated bifurcation diagram. FPGA-based circuit realization is also given for physical verification. Finally, the proposed memristive hyperjerk system is successfully predicted with artificial neural networks for AI based engineering applications.

Die Studie untersucht die systematischen Beziehungen der zentralen Begriffe in Bernard Bolzanos Erkenntnistheorie, die einen logisch-semantischen Realismus mit einer kausalistischen Metaphysik des Geistes verknüpft. Bolzano situiert grundlegende epistemische Aktivitäten wie Vorstellen, Urteilen und Ableiten im Spannungsfeld von logischen Relationen und dem Kausalnexus mentaler Episoden. Die Studie erläutert die Bedeutung der prominenten Begriffe 'Kraft' und 'Wahrscheinlichkeit' im Hinblick auf die erkenntnistheoretischen Belange von Wissen und Rechtfertigung. Der Begriff der Kraft begründet eine kausalistische Metaphysik von Geist und Welt und damit die Bedingungen (...) faktischer Erkenntnisverläufe. Der Begriff der Wahrscheinlichkeit bezeichnet Begründungsrelationen zwischen objektiven Propositionen, die für die rationale Berechtigung von Überzeugungen bestimmend sind. Zusammen konstituieren Faktivität und Normativität von Erkenntnisansprüchen die epistemische Wahrscheinlichkeit der "Zuversicht", die Urteilen einerseits assertive Kraft und andererseits die Berechtigung verleiht, sie als Erkenntnis anzunehmen.

We show that in a simple theory T in which the τf-topologies are closed under projections every type analyzable in a supersimple τf-open set has ordinal SU-rank. In particular, if in addition T is unidimensional, the existence of a supersimple unbounded τf-open set implies T is supersimple. We also introduce the notion of a standard τ-metric and show that for simple theories its completeness is equivalent to the compactness of the τ-topology.

I argue that, contrary to some critics, the notion of conscious experience is a good candidate for denoting a distinct and scientifically interesting phenomenon in the brain. I base this claim mainly on an analysis of neuropsychological data concerning deficits resulting from various types of brain damage as well as some additional supporting empirical evidence. These data strongly point to the hypothesis that conscious experience expresses information that is available for global, integrated, and flexible behavior.

The binding group theorem for stable theories is partially extended to the simple context. Some results concerning internality are proved. We also introduce a ‘small’ normal subgroup G0+ of the automorphism group and show that if p is Q-internal then it has a finite exponent and G/G0+ is interpretable.

The aim of the present paper is to evaluate the notion of collective guilt feeling both in the light of research in affectivity and in collective intentionality. The paper is divided into an introduction and three main sections. Section 1) highlights relevant features of guilt‐family emotions such as the relation between feeling guilt and objective guilt, the relation between feeling guilt and its content, and the relation between feeling guilt and the ‘self’. Moreover, the distinction between feeling guilt and feeling (...) regret is given due attention. Section 2) examines Margaret Gilbert's arguments in favor of a collectivist view of collective guilt feeling , according to which groups do genuinely feel guilt. Against the collectivist position I argue for an individualist ‘membership account’ of collective guilt feeling in terms of individual members' we‐feeling of guilt. The membership account of collective guilt feeling is vindicated on grounds of a naturalist and non‐judgmentalist understanding of emotions, as well as on the logic of personal pronouns. It combines individualism regarding the subject of the feeling with collectivism regarding the irreducibility of we‐feelings and provides, as I further argue, the required moral force attributed to collective guilt feeling. The concern of section 3) is the question of the appropriate emotional response to collective wrongdoing. I argue against the view that group members are categorically ‘committed to feel guilt as a body’ for wrongdoings committed by the group. Given that individual members often do not participate in their groups' wrongdoings, it seems unjust to impose a requirement for feeling guilt upon them. I suggest that in a general account of the appropriate assessment of collective wrongdoing, feeling regret is the better candidate than feeling guilt for the role of the minimally required emotional response.For us collectively to feel guilt over our action A is for us to be jointly committed to feeling guilt as a body over our action A. [. . .] The parties [. . .] constitute, as far as possible, a single subject of guilt feelings .[A] collective cannot respond affectively [. . .], only its constitutive members can. The lack of an affective counter‐response is troubling, because the efficacy of responses of accountability partially depends upon affect. The response of shame, guilt, and regret help to register the significance of the harm. (shrink)

The recent emergence of machine-manipulated media raises an important societal question: How can we know whether a video that we watch is real or fake? In two online studies with 15,016 participants, we present authentic videos and deepfakes and ask participants to identify which is which. We compare the performance of ordinary human observers with the leading computer vision deepfake detection model and find them similarly accurate, while making different kinds of mistakes. Together, participants with access to the model’s prediction (...) are more accurate than either alone, but inaccurate model predictions often decrease participants’ accuracy. To probe the relative strengths and weaknesses of humans and machines as detectors of deepfakes, we examine human and machine performance across video-level features, and we evaluate the impact of preregistered randomized interventions on deepfake detection. We find that manipulations designed to disrupt visual processing of faces hinder human participants’ performance while mostly not affecting the model’s performance, suggesting a role for specialized cognitive capacities in explaining human deepfake detection performance. -/- .

The modern ethical framework demands informed consent for research participation that includes disclosure of material information, as well as alternatives. The severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) pandemic (COVID-19) results in illness that often involves rapid deterioration. Despite the urgent need to find therapy, obtaining informed consent for COVID-19 research is needed. The current pandemic presents three types of challenges for investigators faced with obtaining informed consent for research participation: (1) uncertainty over key information to informed consent, (2) time (...) and pressure constraints, and (3) obligations regarding disclosure of new alternative therapies and re-consent. To mitigate consenting challenges, primary investigators need to work together to jointly promote urgent care and research into COVID-19. Actions they can take include (1) prior plan addressing ways to incorporate clinical research into clinical practice in emergency, (2) consider patients vulnerable with early deliberation on the consent process, (3) seek Legally Authorized Representatives (LARs), (4) create a collaborative research teams, (5) aim to consent once, despite evolving information during the pandemic, and (6) aim to match patients to a trial that will most benefit them. The COVID-19 pandemic both exacerbates existing challenges and raises unique obstacles for consent that require forethought and mindfulness to overcome. While research teams and clinician-investigators will need to be sensitive to their own contexts and adapt solutions accordingly, they can meet the challenge of obtaining genuinely informed consent during the current pandemic.

The paper discusses Bernard Bolzano’s epistemological approach to believing and knowing with regard to the epistemic requirements of an axiomatic model of science. It relates Bolzano’s notions of believing, knowing and evaluation to notions of infallibility, immediacy and foundational truth. If axiomatic systems require their foundational truths to be infallibly known, this knowledge involves both evaluation of the infallibility of the asserted truth and evaluation of its being foundational. The twofold attempt to examine one’s assertions and to do so by (...) searching for the objective grounds of the truths asserted lies at the heart of Bolzano’s notion of knowledge. However, the explanatory task of searching for grounds requires methods that cannot warrant infallibility. Hence, its constitutive role in a conception of knowledge seems to imply the fallibility of such knowledge. I argue that the explanatory task contained in Bolzanian knowing involves a high degree of epistemic virtues, and that it is only through some salient virtue that the credit of infallibility can distinguish Bolzanian knowing from a high degree of Bolzanian believing.

We extend the dichotomy between 1-basedness and supersimplicity proved in Shami :309–332, 2011). The generalization we get is to arbitrary language, with no restrictions on the topology [we do not demand type-definabilty of the open set in the definition of essential 1-basedness from Shami :309–332, 2011)]. We conclude that every hypersimple unidimensional theory that is not s-essentially 1-based by means of the forking topology is supersimple. We also obtain a strong version of the above dichotomy in the case where the (...) language is countable. (shrink)

Let T be simple, work in Ceq over a boundedly closed set. Let p ∈ S(θ) be internal in a quasi-stably-embedded type-definable set Q (e.g., Q is definable or stably-embedded) and suppose (p, Q) is ACL-embedded in Q (see definitions below). Then Aut(p/Q) with its action on pC is type-definable in Ceq over θ. In particular, if p ∈ S(θ) is internal in a stably-embedded type-definable set Q, and pC υ Q is stably-embedded, then Aut(p/Q) is type-definable with its action (...) on pC. (shrink)

The non‐forking‐instances topology (NFI topology) is a topology on the Stone space of a theory T that depends on a reduct of T. This topology has been used in [6] to describe the set of universal transducers for (invariants sets that translate forking‐open sets in to forking‐open sets in T). In this paper we show that in contrast to the stable case, the NFI topology need not be invariant over parameters in but a weak version of this holds for any (...) simple T. We also note that for the lovely pair expansions, of theories with the weak non‐finite cover property (wnfcp), the topology is invariant over in. (shrink)

We show that if p is a real type which is almost internal in a formula φ in a simple theory, then there is a type p' interalgebraic with a finite tuple of realizations of p, which is generated over φ. Moreover, the group of elementary permutations of p' over all realizations of φ is type-definable.

I study a market model in which profit-maximizing firms compete in multidimensional pricing strategies over a consumer, who is limited in his ability to grasp such complicated objects and therefore uses a sampling procedure to evaluate them. Firms respond to increased competition with an increased effort to obfuscate, rather than with more competitive pricing. As a result, consumer welfare is not enhanced and may even deteriorate. Specifically, when firms control both the price and the quality of each dimension, and there (...) are diminishing returns to quality, increased competition implies an efficiency loss which is entirely borne by consumers.

This paper presents an extended version of the Quantified Argument Calculus (Quarc). Quarc is a logic comparable to the first-order predicate calculus. It employs several nonstandard syntactic and semantic devices, which bring it closer to natural language in several respects. Most notably, quantifiers in this logic are attached to one-place predicates; the resulting quantified constructions are then allowed to occupy the argument places of predicates. The version presented here is capable of straightforwardly translating natural-language sentences involving defining clauses. A three-valued, (...) model-theoretic semantics for Quarc is presented. Interpretations in this semantics are not equipped with domains of quantification: they are just interpretation functions. This reflects the analysis of natural-language quantification on which Quarc is based. A proof system is presented, and a completeness result is obtained. The logic presented here is capable of straightforward translation of the classical first-order predicate calculus, the translation preserving truth values as well as entailment. The first-order predicate calculus and its devices of quantification can be seen as resulting from Quarc on certain semantic and syntactic restrictions, akin to simplifying assumptions. An analogous, straightforward translation of Quarc into the first-order predicate calculus is impossible. (shrink)
