Sensation elicited by a skin stimulus was subjectively reported to feel stronger when followed by a stimulus to somatosensory cerebral cortex , even when C was delayed by up to 400 ms or more. This expands the potentiality for retroactive effects beyond that previously known as backward masking. It also demonstrates that the content of a sensory experience can be altered by another cerebral input introduced after the sensory signal arrives at the cortex. The long effective S-C intervals (...) support the thesis that a duration of cortical activity of up to 0.5 s is required before awareness of a sensory stimulus is developed. (shrink)

Zusammenfassung Der vorliegende Beitrag analysiert die Bedeutung der Idee der umma in der „Muslimischen Jugend in Deutschland e. V.“ und der sie umgebenden pop-islamischen Szene entlang der Frage sozialer Grenzziehungsprozesse. Es soll gezeigt werden, dass soziale Grenzen nicht nur durch Zuschreibungs- und Exklusionsprozesse von außen konstruiert, sondern auch entlang von gemeinschaftsbildenden Identifikationsprozessen junger Musliminnen und Muslime hergestellt werden. Indem individuelle und kollektive Bedeutungen der Umma im Kontext des Untersuchungsfeldes erfasst werden, werden Prozesse der Vergemeinschaftung ebenso in den Blick genommen wie (...) damit verbundene soziale Distinktionen, Exklusionen und Abwertungen. Dabei zeigt sich, dass soziale Grenzziehungsprozesse der pop-islamischen Szene sowohl gegenüber der deutschen Mehrheitsgesellschaft als auch gegenüber verschiedenen islamischen Strömungen je situations- und kontextabhängig ausgehandelt werden und sich als gleichzeitige Suche nach Partizipation und Abgrenzung bzw. Inklusion und Exklusion beschreiben lassen. (shrink)

The article is devoted to certain fundamental and discussed threads defined as dilemmas of political anthropology. Starting from specific rudimentary descriptions of human nature, the natural state or natural man, initiated by thinkers described by Barnard as “precursors of anthropology,” as well as referring to the problems of contemporary political philosophy, the papers aims to bring closer the issues concerning the fall of human and his “regeneration,” the “mask regime,” tensions between a human being and society, conflict and cooperation; dialogue (...) and antagonism. The proposed interpretations of the thoughts of Hobbes, Machiavelli, or Rousseau have the character of “retroactive reading.” It means that the references made to historical-philosophical examples activate the contexts of contemporary thought, or even give them new meanings, and at the same time trigger a thought that leans towards the future.

The paper offers a reconstruction of the logics of jazz improvisation that is drawing on Žižek’s Work on Hegel. A basic concept of Žižek’s reading of Hegel consists in the concept of Retroactivity as the temporality that is characteristic of what Hegel understands as the development of history. The logic of retroactivity cannot be understood in terms of a classical teleological account but rather draws upon the idea of incommensurable events: Each historical situation is presupposing its own preconditions in a (...) way that the contingent is transformed into necessity. The paper discusses the structure of the temporality of jazz in such a way that it can be informed by Žižek’s thoughts on the temporal logic of history. (shrink)

This article affords particular attention to the relationship between memory, the narrativization of news and its linear construction, conceived as journalism’s ‘memory- work’. In elaborating upon this ‘work’, it is proposed that the Hegelian notion of retroactive causation (as used by Slavoj Žižek) can examine how analyses of news journalists ‘retroactively’ employ the past in the temporal construction of news. In fact, such retroactive (re)ordering directs attention to the ways in which journalists contingently select ‘a past’ to confer (...) meaning on the present. With regard to current literature, it is noted that a retroactive analysis can highlight two important dialectics within the practice of news journalism: 1) the relation between contingency and necessity; and, 2) the relation between content and form. Indeed, it is argued that this theoretical account offers a novel approach to examining the significance of memory in news journalism as well as the inconsistencies which underscore journalism’s memory-work. It is in accordance with such inconsistency that broader reflections on time, temporality and our relations to the past can be made. (shrink)

During emerging public health crises, both policymakers and members of the public are looking to scientific experts to provide guidance. Even in cases where there are significant uncertainties, there is pressure for experts to “speak with one voice” to avoid confusion, allow officials to make evidence-based decisions rapidly, and encourage public support for such decisions. This can lead experts to engage in masking of information about the state of the science or regarding assumptions involved in policy recommendations. Although experts (...) might have good reasons for masking disagreements, uncertainties, or assumptions when offering policy advice, we argue that this strategy can result in epistemic harms. Using the case of the COVID-19 pandemic, we show that public health authorities masked two types of information necessary for laypersons to evaluate public health recommendations: (1) experts’ disagreements about the scientific evidence and (2) the role of values in making inferences from the science to policy positions. We contend that this resulted in epistemic harms against laypeople that provide a pro tanto case against masking information. We further argue that when the science is in flux and policies need to be implemented despite significant uncertainties, there is an all-things-considered case against masking the types of information discussed.

John Fischer has recently argued that the value of acting freely is the value of self-expression. Drawing on David Velleman’s earlier work, Fischer holds that the value of a life is a narrative value and free will is valuable insofar as it allows us to shape the narrative structure of our lives. This account rests on Fischer’s distinction between regulative control and guidance control. While we lack the former kind of control, on Fischer’s view, the latter is all that is (...) needed for self-expression. I first develop Fischer’s narrative account, focusing on his reliance on temporal loops as giving us control over the value of our lives. Second, I argue that the narrative account grants us greater power over the past than Fischer would allow: since narrative allows not only for changes in how we feel about episodes in our past but what those episodes in fact were, it allows for a kind of retroactive self-constitution. Finally, I suggest that this modification of the narrative view opens the possibility of a conception of freedom far stronger than guidance control. It does not give us the libertarian control over whether to choose A or B in the present, but it does provide a measure of control over the sort of person an agent has been, and thus whether she is the sort of person who will choose A or B in the future.

Our visual system can process information at both conscious and unconscious levels. Understanding the factors that control whether a stimulus reaches our awareness, and the fate of those stimuli that remain at an unconscious level, are the major challenges of brain science in the new millennium. Since its publication in 1984, Visual Masking has established itself as a classic text in the field of cognitive psychology. In the years since, there have been considerable advances in the cognitive neurosciences, and (...) a growth of interest in the topic of consciousness, and the time is ripe for a new edition of this text. Where most current approaches to the study of visual consciousness adopt a 'steady-state' view, the approach presented in this book explores its dynamic properties. This new edition uses the technique of visual masking to explore temporal aspects of conscious and unconscious processes down to a resolution in the millisecond range. The 'time slices' through conscious and unconscious vision revealed by the visual masking technique can shed light on both normal and abnormal operations in the brain. The main focus of this book is on the microgenesis of visual form and pattern perception - microgenesis referring to the processes occurring in the visual system from the time of stimulus presentation on the retinae to the time, a few hundred milliseconds later, of its registration at conscious or unconscious perceptual and behavioural levels. The book takes a highly integrative approach by presenting microgenesis within a broad context encompassing visuo-temporal phenomena, attention, and consciousness. (shrink)

There are many reasons why scientific experts may mask disagreement and endorse a position publicly as “jointly accepted.” In this paper I consider the inner workings of a group of scientists charged with deciding not only a technically difficult issue, but also a matter of social and political importance: the maximum acceptable dose of radiation. I focus on how, in this real world situation, concerns with credibility, authority, and expertise shaped the process by which this group negotiated the competing virtues (...) of reaching consensus versus reporting accurately the nature and degree of disagreement among them.

In this paper I expose Caligaris and Starostas argument on the logical character of the initial moments in Hegels and Marxs dialectics; I argue that the categories of Marxs theory of labor-value must be read in such a way that value, or substance of value, is taken non-substantially, arising only with the emergence of exchange value, or the value-form; Finally, I attempt to justify this reading from the standpoint of the idea of self-posited presuppositions, as developed by Slavoj Zizek.

Masks, interferers, finks, reverse finks, and mimickers are troublesome for powers metaphysics insofar as the latter concedes that there are powers with essential stimuli/activation conditions. In this article, I aim at offering a novel approach for solving this problem. In Section 1, I shall present the problem; and in Section 2, I shall briefly show how it also arises within non‐reductive views of powers. Subsequently, in Section 3, I shall examine the failure of the ceteris paribus solution. The pars construens (...) will begin in Section 4, where I shall distinguish between the activation conditions, the background conditions, and the possession conditions of a power. Within each category, I shall draw further distinctions. In Section 5, I shall demonstrate how such distinctions may ground a solution to our problem. Finally, in Section 6, I shall anticipate and reply to four objections. (shrink)

Despite its plausibility, I mean to resist this argument. I will reject premise 1 on the grounds that dying may be atemporally bad for us. I will also reject premise 3. Some postmortem events are bad for some of us while we are alive. But I am not going to report some new exotic particle that makes backwards causation possible. As far as I know, 6 is true. If an event is responsible for a harm that we incur before the (...) event itself occurs, it might be said to harm us retroactively ; if when or after it occurs, it might be said to harm us proactively . My view is that some postmortem events harm us retroactively, but without backwards causation (Pitcher 1984). (shrink)

An object's disposition to A in circumstances C is masked if circumstances C obtain without the object Aing. This paper explores an analogous sense in which abilities can be masked, and it uses the results of this exploration to motivate an analysis of agents' abilities in terms of dispositions. This analysis is then shown to provide the resources to defend a version of the Principle of Alternate Possibilities against Frankfurt-style counterexamples. Although this principle is often taken to be congenial to (...) incompatibilism concerning free action and determinism, the paper concludes by using the dispositional analysis of abilities to argue for compatibilism, and to show why the 'master argument' for incompatibilism is unsound.

To date, COVID-19 has spread across the world, changing our way of life and forcing us to wear face masks. This report demonstrates that face masks influence the human ability to infer emotions by observing facial configurations. Specifically, a mask obstructing a face limits the ability of people of all ages to infer emotions expressed by facial features, but the difficulties associated with the mask’s use are significantly pronounced in children aged between 3 and 5 years old. These findings are (...) of essential importance, as they suggest that we live in a time that may potentially affect the development of social and emotion reasoning, and young children’s future social abilities should be monitored to assess the true impact of the use of masks.

We consider several thought and practical experiments, and variations thereof, from which the existence can be inferred of retroactive effects on the assumptions of conservation of linear and angular momentum and of realism defined in a wide sense. Such conclusion is made less counterintuitive by research into the proper physical background of the relativistic length contraction of a moving arrow, viz. the fact that the universe is four-dimensional indeed. In one of the experiments considered, the evidence of retroactivity is (...) more striking and can more easily be actually demonstrated than was the case in earlier proofs. (shrink)

Reluctance to adopt mask-wearing as a preventive measure is widely observed in many Western societies since the beginning of the COVID-19 pandemics. This reluctance toward mask adoption, like any other complex social phenomena, will have multiple causes. Plausible explanations have been identified, including political polarization, skepticism about media reports and the authority of public health agencies, and concerns over liberty, amongst others. In this paper, we propose potential explanations hitherto unnoticed, based on the framework of epistemic injustice. We show how (...) testimonial injustice and hermeneutical injustice may be at work to shape the reluctant mask adoption at both the societal and individual levels. We end by suggesting how overcoming these epistemic injustices can benefit the global community in this challenging situation and in the future. (shrink)

The necessity of wearing masks in response to the spread of the Covid-19 took Europe and the USA by surprise. Legislation needed to be enacted to enforce the obligation on citizens not used to such practices. The authors investigate the semiotic function of masks, legislations enacted to enforce their usage in public places, and the mask-related discourse with a view to seeing how societies reacted to this imposition. A broad semiotic perspective is provided to analyze different attitudes and types of (...) MRD that have emerged in Poland, France, and the USA. (shrink)

This chapter discusses the retroactivity problem and how it arises when the idea that events occurring after a person’s life can harm that person is pursued. The common objection to this dilemma is the “no subject” type of response. The retroactivity problem is the result of making several assumptions jointly, many of which are initially plausible but none of which are actually defended. The first of these assumptions is referred to as Worse-Off, which states that an event harms a person (...) only if it makes him worse off than he would have been if the event had not occurred. The second assumption, implied by the first, is referred to as Welfare, which states that an event harms a person only if it makes it the case that his welfare is lower than it would have been if the event had not occurred.
