This book provides a general survey of the main concepts, questions and results that have been developed in the recent interactions between quantum information, quantum computation and logic. Divided into 10 chapters, the books starts with an introduction of the main concepts of the quantum-theoretic formalism used in quantum information. It then gives a synthetic presentation of the main “mathematical characters” of the quantum computational game: qubits, quregisters, mixtures of quregisters, quantum logical gates. Next, the book investigates the puzzling entanglement-phenomena (...) and logically analyses the Einstein–Podolsky–Rosen paradox and introduces the reader to quantum computational logics, and new forms of quantum logic. The middle chapters investigate the possibility of a quantum computational semantics for a language that can express sentences like “Alice knows that everybody knows that she is pretty”, explore the mathematical concept of quantum Turing machine, and illustrate some characteristic examples that arise in the framework of musical languages. The book concludes with an analysis of recent discussions, and contains a Mathematical Appendix which is a survey of the definitions of all main mathematical concepts used in the book. (shrink)

The similarities in the philosophies of Parmenides and Śaṅkara1 need to be better understood than they have been so far. I will argue that the goal they share can be characterized as that of leading their audiences to nondual reality, which is the only trustworthy knowledge or experience one can have. They refer to this nondual reality respectively as being and Brahman. Even if the phrase ‘nondual reality’ or ‘nondual experience’ strikes many readers as controversial if applied to Parmenides’ being, (...) it agrees with the ‘fashionable’ Parmenides interpretations that insist that Parmenides’ laws of thought, such as the impossibility of knowing not-being,2 will enable us to understand what being is; and it makes..

Some Presentists—according to whom everything is present—identify instants of time with propositions of a certain kind. However, the view that times are propositions seems to be at odds with Presentism: if there are times then there are past times, and therefore things that are past; but how could there be things that are past if everything is present? In this paper, we describe the Presentist view that times are propositions ; we set out the argument that Presentism is incompatible with (...) the view that times are propositions ; and then we describe three possible responses to that argument on behalf of Presentists who identify times with propositions. We argue that each of these responses comes with significant costs. Finally, we describe a fourth possible response—according to which times are irreducibly higher-order entities—which appears to avoid the costs of the other three. We also describe and respond to two objections to the higher-order strategy. (shrink)

The current situation around COVID-19 portrays a threat to us in several ways: It imposes uncertainty, a lack of control and reminds us of our own mortality. People around the world have reacted to these threats in seemingly unrelated ways: From stockpiling yeast and toilet paper to favoring nationalist ideas or endorsing conspiratorial beliefs. According to the General Process Model of Threat and Defense the confrontation with a threat - a discrepant experience - makes humans react with both proximal and (...) distal threat responses. While the proximal response manifests in behavioral inhibition that leads to heightened anxious arousal and vigilance, distal responses seek to lower behavioral inhibition and the associated state of anxiety and vigilance through engaging in distal defenses. In the present research, we propose that the reactions to COVID-19 may represent distal defense strategies to the pandemic (in the form of environmental or group related worldview defenses) and therefore can be explained and forecasted by the model. Thus we hypothesized increased perceived COVID-19 threat perception to lead to a proximal threat response in the form of heightened behavioral inhibition. This, in return, should enhance the use of distal defenses (i.e.: several ingroup biases, system justification and conspiratorial beliefs) overlapping with the reactions observed as a response to COVID-19. This hypothesized mediated effect of increased perceived COVID-19 threat on distal defenses was tested in two pre-registered studies: In Study 1 (N = 358) results showed perceived COVID-19 threat to be related to behavioral inhibition and in turn to be associated with increased distal defenses (i.e., higher entitativity, control restoration motivation, passive party support). In Study 2 (N = 348) we manipulated COVID-19 threat salience and found results suggesting the distal defenses of system justification and conspiratorial beliefs to be mediated by the proximal threat response. The results of the present research hint towards a common mechanism through which the seemingly unrelated reactions to COVID-19 can be explained. The results might help to predict future behavior during the COVID-19 pandemic and design measures to counteract detrimental effects of the pandemic. (shrink)

The purpose of this paper is to explore the connection between change and the B-theory of time, sometimes also called the Scientific view of time, according to which reality is a four-dimensional spacetime manifold, where past, present and future things equally exist, and the present time and non-present times are metaphysically the same. I argue in favour of a novel response to the much-vexed question of whether there is change on the B-theory or not. In fact, B-theorists are often said (...) to hold a ‘static’ view of time. But this far from being innocent label: if the B-theory of time presents a model of temporal reality that is static, then there is no change on the B-theory. From this, one can reasonably think as follows: of course, there is change, so the B-theory must be false. What I plan to do in this paper is to argue that in some sense there is change on the B-theory, but in some other sense, there is no change on the B-theory. To do so, I present three instances of change: Existential Change, namely the view that things change with respect to their existence over time; Qualitative Change, the view that things change with respect to how they are over time; Propositional Change, namely the view that things (i.e. propositions) change with respect to truth value over time. I argue that while there is a reading of these three instances of change that is true on the B-theory, and so there is change on the B-theory in this sense, there is a B-theoretical reading of each of them that is not true on the B-theory, and therefore there is no change on the B-theory in this other sense.

Drawing on philosophy, law and political science, and on a wealth of practical experience delivering emergency medical services in conflict-ridden settings, Lepora and Goodin untangle the complexities surrounding compromise and complicity.

Compromise arises in contexts where irreconcilable claims must nonetheless somehow be resolved. Ordinary people in everyday life, politicians and artists, doctors engaging in research, humanitarian workers providing aid in the midst of war – all of them will have faced situations where compromise appeared to be the only reasonable option, and yet will have felt that there was nevertheless something deeply wrong with it. The aim of this paper is to help make sense of that sentiment. The focus of this (...) paper will be on some aspects of the morality of compromise. Its lynchpin will be to construe compromise as a joint action, in particular, a joint wrongdoing – taking part in, and sharing responsibility for, the doing of things that are wrong from the point of view of those who are the parties to the compromise. The question of ‘what is wrong with compromise?’ is thus recast as a question of ‘what is my part in the wrongs being done as part of the compromise?’ It is tempting to suppose that a compromise serves to dilute personal responsibility, parsing it out among parties to the compromise. Viewing a compromise as a joint action, in contrast, will help us to see how a compromise actually increases responsibility among parties to it. They are now jointly collaborating in some action that each of them sees as wrong, at least in part (albeit in differing parts). Discussions of compromise traditionally prioritize the inter-personal aspect – compromise, in the transitive form of ‘compromising with’ someone. But I argue that the intransitive form – ‘compromise of’ – deserves pride of place. The reason for prioritizing the intransitive ‘compromise of’ is simple: that is what is involved in the intra-personal calculation that must, of necessity, go on inside one's own head in the process of deciding whether or not to agree to a 'compromise with' someone else. In this paper I shall concentrate specifically on compromises of principles, or (more precisely) on ‘matters of principled concern to the compromising parties’. Not only is that the most troubling and morally problematic sort of compromise, it is also logically the most central case. I demonstrate that that is so by shifting the focus from inter-personal compromise to the more fundamental intra-personal process underlying it – the compromise we are involved in when adjudicating among our own conflicting values, to decide whether or not to agree to a compromise of the inter-personal sort. This is the subject of the first section of the paper below. Compromise involves resolving conflicts of principles through mutual concessions that are accepted and undertaken by all parties. Doing so may be on-balance desirable, not only from some larger perspective (of social peace, or whatever) but also from each party's own perspective. Nevertheless, from each party's perspective, compromise necessarily involves interacting with, and sometimes contributing to, wrongdoing. Morally, something is lost, even if more is gained on balance. (shrink)

To our knowledge, this is one of the first studies to test different theoretical models of working memory in childhood based on a computerized assessment. We tested this across several countries: Argentina, Brazil, Canada, Italy, and UK. The present study addressed the wider macro-cultural context and how this impacts working memory. We used two economic indices to characterize the participating countries and ranked the countries based on the Global Index of Cognitive Skills and Educational Attainment. Children between 5 and 10 (...) years completed the same set of short-term and working memory tests. There were two main findings. First, there was a similar pattern in verbal working memory across countries, which suggests that this skill may be relatively consistent across different cultural groups. In contrast, the pattern for visuo-spatial working memory was different across countries, which may explained by cultural differences and educational rankings of the countries. The second main finding was that both a domain-general model and a domain-specific model provided a reasonably good fit with the data, there was the high relationship between the verbal and visuo-spatial working memory constructs across the countries in the latter model. Thus, it may be a more parsimonious choice to rely on a three-factor model. The data also suggest culture-similar patterns in a computerized assessment of working memory. (shrink)

After initially emerging in China, the coronavirus (COVID-19) outbreak has advanced rapidly. The World Health Organization (WHO) has recently declared it a pandemic, with Europe becoming its new epicentre. Italy has so far been the most severely hit European country and demand for critical care in the northern region currently exceeds its supply. This raises significant ethical concerns, among which is the allocation of scarce resources. Professionals are considering the prioritisation of patients most likely to survive over those with remote (...) chances, and this news has triggered an intense debate about the right of every individual to access healthcare. The proposed analysis suggests that the national emergency framework in which prioritisation criteria are currently enforced should not lead us to perceive scarce resources allocation as something new. From an ethical perspective, the novelty of the current emergency is not grounded in the devastating effects of scarce resources allocation, which is rife in recent and present clinical practice. Rather, it has to do with the extraordinarily high number of people who find themselves personally affected by the implications of scarce resources allocation and who suddenly realise that the principle of ‘equals should be treated equally’ may no longer be applicable. Along with the need to allocate appropriate additional financial resources to support the healthcare system, and thus to mitigate the scarcity of resources, the analysis insists on the relevance of a medical ethics perspective that does not place the burden of care and choice solely on physicians.

Torture is unethical and usually counterproductive. It is prohibited by international and national laws. Yet it persists: according to Amnesty International, torture is widespread in more than a third of countries. Physicians and other medical professionals are frequently asked to assist with torture. -/- Medical complicity in torture, like other forms of involvement, is prohibited both by international law and by codes of professional ethics. However, when the victims of torture are also patients in need of treatment, doctors can find (...) themselves torn. To accede to the requests of the torturers may entail assisting or condoning terrible acts. But to refuse care to someone in medical need may seem like abandoning a patient and thereby fail to exhibit the beneficence expected of physicians. -/- In this paper, we argue that this dilemma is real and that sometimes the right thing for a doctor to do, overall, is to be complicit in torture. Though complicity in a wrongful act is itself prima facie wrongful, this judgment may be outweighed by other factors. We propose three criteria for analyzing how those factors apply to particular cases of medical complicity in torture. (shrink)

Here I present the first version of the transcription of the Commentarius in Metaphysicam by Konrad Graf from Cod. Pp 183 4°, Teil 2, Zentral- und Hochschulbibliothek Luzern [ZHB], Sondersammlung (ff. 1r-56v), which collects Graf's lectures in metaphysics, held at the Lucerne Gymnasium in 1635-36. The transcription of the text was carried out at the Lucerne Faculty of Theology within the SNSF project "Zwischen monastischer und reformierter Metaphysik. Die schweizerische 'Wiege' der Ontologie im Zeitalter der Reformation" (SNSF project 100012_192559 - (...) applicant: Prof. Dr. Giovanni Ventimiglia (TF- University of Lucerne), Employees: Marco Lamanna, Chiara Paladini. The project aimed to redefine the "cartography" of the Reformation in Switzerland on the traces of metaphysics teaching (Reportationes) in Swiss educational institutions and monastic poles, and thereby to gain a precise place for Swiss studies in the panorama of research on metaphysics and ontology in the early modern period. The project was based on a preliminary investigation that made it possible to recover new texts transmitting lessons on metaphysics held in Lucerne and Engelberg. The method was 1. to produce a systematic and comprehensive documentation based on an index of manuscripts and printed texts, most of them already identified, which testify to the existence of a cultural flourishing in Switzerland that has so far remained unexplored. 2. this documentation should be placed on a solid textual basis by transcribing and eventually critically editing those texts judged to be of interest in terms of their content and influence, in order to make them accessible to the scholarly community and to readers. 3. finally, we will examine the specific aspects of the teachings transmitted in these manuscripts.
