We present an experimental test of the validity of the Pauli Exclusion Principle for electrons based on the concept put forward a few years ago by Ramberg and Snow. In this experiment we perform a very accurate search of X-rays from the Pauli-forbidden atomic transitions of electrons in the already filled 1S shells of copper atoms. Although the experiment has a simple structure, it poses deep conceptual and interpretational problems. Here we describe the experimental method and recent experimental results, which (...) we interpret as an upper limit for the probability to violate the Pauli Exclusion Principle. We present also future plans to upgrade the experimental apparatus using Silicon Drift Detectors. (shrink)

In this paper we describe an experimental test of the validity of the Pauli Exclusion Principle (for electrons) which is based on a straightforward idea put forward a few years ago by Ramberg and Snow (Phys. Lett. B 238:438, 1990). We perform a very accurate search of X-rays from the Pauli-forbidden atomic transitions of electrons in the already filled 1S shells of copper atoms. Although the experiment has a very simple structure, it poses deep conceptual and interpretational problems. Here we (...) describe the experimental method and recent experimental results, which we interpret in the framework of quon theory. We also present future plans to upgrade the experimental apparatus using Silicon Drift Detectors. (shrink)

We present the idea of searching for X-rays as a signature of the mechanism inducing the spontaneous collapse of the wave function. Such a signal is predicted by the continuous spontaneous localization theories, which are solving the “measurement problem” by modifying the Schrödinger equation. We will show some encouraging preliminary results and discuss future plans and strategy.

This book closely examines our commonly held beliefs about human suffering, and offers unique insights into God's role in why we suffer. Dr. Perri critically examines what it means to be human from a Judeo-Christian perspective, and extrapolates from the work of Carl Gustav Jung showing a deeply complex development of human transcendence in human suffering. On an interpersonal level, Dr. Perri elaborates on the work of Martin Buber and Emanuel Levinas and shows how our suffering can be shared and (...) lessened by our unconditionality and presence for the other. Scriptural passages are quoted from both the Hebrew and New Testament texts, and are used to depict the suffering of humankind as seen in the face of Job. It was this face, according to Perri, that Jesus saw in the faces of those He came to redeem, and that ultimately brought Him to the crucifix of redemption. Dr. Perri challenges Sartre's position that our existence precedes our essence, and draws on the work of Abraham Joshua Heschel and Christian theology in this regard. He further elaborates a neurodevelopmental paradigm that creates essence as the basis of our freedom to choose. This book can be read and studied by both professionals in the helping and healing professions, and lay persons seeking to better understand our suffering, and how to better help those who suffer. Dr. Perri offers specific ways in how to be present for those who suffer, how to read and receive the hidden language of human suffering, and how to use silence as a communication skill. (shrink)

Moral philosophers agree that welfare matters. But they disagree about what it is, or how much it matters. In this vital new work, Wayne Sumner presents an original theory of welfare, investigating its nature and discussing its importance. He considers and rejects all notable theories of welfare, both objective and subjective, including hedonism and theories founded on desire or preference. His own theory connects welfare closely with happiness or life satisfaction. Reacting against the value pluralism that currently dominates moral philosophy, (...) he advances welfare as the only basic ethical value. He concludes by discussing the implications of this thesis for ethical and political theory. Written in clear, non-technical language, and including a definitive survey of other work in this area, Sumner's book is essential reading for moral philosophers, political theorists, and welfare economists.

The draft Code of Conduct for Research is an important initiative towards assisting the scientific community in complying with the provisions of the Protection of Personal Information Act 4 of 2013 (POPIA). However, its approach towards cross-border data sharing should be reconsidered to clarify the ambiguities inherent in the legal requirements for the cross-border sharing of health data in the POPIA. These ambiguities include the concept of ‘transfer of information’, the application of adequacy as a legal mechanism for transfer, the (...) nature of consent for cross-border sharing and the scope of the recipient third party. We suggest that the draft Code of Conduct for Research can be improved by: Explaining or defining the concept of ‘transfer of information’ and when it applies to cross-border sharing in research Clarifying the application of adequacy as a legal mechanism for transfer vis-à-vis the other alternatives Expanding on the interpretation and application of consent as a legal mechanism for cross-border transfers Expanding the category of persons who may be recipients of personal information in a third country.

Language, like other human traits, could only have evolved during one or more stages of development. We enlist the theoretical framework of human life history to account for certain aspects of linguistic evolution, with special reference to initial phases in the process. It is hypothesized that selection operated at several developmental stages, the earlier ones producing new behaviors that were reinforced by additional, and possibly more powerful, forms of selection during later stages, especially adolescence and early adulthood. Peer commentaries have (...) provided opportunities to explain human life history more comprehensively, and to add details to our account of spoken language. We made no attempt to explain syntax in the target article, but we propose here that selection for “vocal plumage” may have increased our species’ capacity for utterance complexity, a development that would have benefited all levels of language.

Due to the pandemic and the suspension of in-person school classes, there was an interruption in the meals served to approximately 40 million students who benefited from the Brazilian National School Feeding Program (PNAE). This article describes two case studies, comparing the strategies adopted by two municipalities for maintaining school feeding during the Covid-19 pandemic in the northern region of the state of Rio de Janeiro, Brazil, and discuss possible impacts of these strategies on food and nutrition security. These municipalities (...) together cover about 81% of the population in the region. In July 2020, we conducted interviews with PNAE municipal managers, following a qualitative approach. We discuss the results in relation to existing Brazilian guidance on food and nutrition security. The municipalities have developed distinct strategies to overcome operational obstacles and maintain PNAE goals, such as distributing food kits and making cash transfers to students’ families. The main determinants of these strategies are financial availability, the relationship between municipal teams and school communities, and the pre-pandemic PNAE logistics and management. Depending on the strategy and duration of the pandemic, the impacts on food and nutrition security can be wide-ranging, affecting food quality and local farmers who sell products to PNAE. It is necessary to acknowledge that this is not a short-term pandemic and find ways to perform school feeding in accordance with PNAE criteria. (shrink)

Rationality requires us to respond to apparent normative reasons. Given the independence of appearance and reality, why think that apparent normative reasons necessarily provide real normative reasons? And if they do not, why think that mistakes of rationality are necessarily real mistakes? This paper gives a novel answer to these questions. I argue first that in the moral domain, there are objective duties of respect that we violate whenever we do what appears to violate our first-order duties. The existence of (...) these duties of respect, I argue, ensures that apparent moral reasons are exceptions to the independence of appearance and reality. I then extend these arguments to the domain of overall reason. Just as there are objective duties of respect for moral reasons that explain moral blameworthiness, so there are objective duties of respect for reasons that explain blameworthiness in the court of overall reason. The existence of these duties ensures that apparent reasons are exceptions to the independence of appearance and reality. (shrink)

Bundle theory takes objects to be bundles of properties. Some bundle theorists take objects to be bundles of instantiated universals, and some take objects to be bundles of tropes. Tropes are instances of properties: some take instantiated universals to be tropes, while others deny the existence of universals and take tropes to be ontologically fundamental. Historically, the bundling relation has been taken to be a primitive relation, not analyzable in terms of or ontologically reducible to some other relation, and has (...) been variously characterized as, e.g., “compresence,” “concurrence,” or “consubstantiation.” Bertrand Russell (1940) defends compresence of universals, and Hector-Neri Castañeda (1974) defends consubstantiation of universals. John Bacon (1995) defends concurrent tropes and Keith Campbell (1990) defends compresent tropes. Jonathan Schaffer (2001) bucks this trend, endorsing compresence understood as co-location in spacetime, but this brings with it undesireable consequences such as the impossibility of distinguishing between objects (such as electrons or other microentities) with the same location. Mereological bundle theory improves upon traditional bundle theory by taking the primitive relation of bundling to be the more familiar relation of fusing or composing, such that objects are fusions of properties or fusions of property instances. Hence, mereological bundle theorists endorse a property mereology: a mereology where properties or property instances can be parts of objects. An advantage of the approach derives from the fact that standard mereologies take composition to be primitive or define it using a different primitive mereological notion (such as primitive parthood). Thus, taking the basic primitive of bundle theory to be composition can reduce the need for.. (shrink)

Adequate epistemic justification is best conceived as the appearance, over time, of knowledge to the subject. ‘Appearance’ is intended literally, not as a synonym for belief. It is argued through consideration of examples that this account gets the extension of ‘adequately justified belief’ at least roughly correct. A more theoretical reason is then offered to regard justification as the appearance of knowledge: If we have a knowledge norm for assertion, we do our best to comply with this norm when we (...) express as assertions only beliefs that appear to us to be knowledge. If we are doing our best, there is little point in further sanctions. So a norm of knowledge for assertion would lead to a secondary norm of justified belief as the appearance of knowledge, marking a point at which our assertions may be corrected but should not be blamed.

This book is a major work in the history of ethics, and provides the first study of early modern British philosophy in several decades. Professor Darwall discerns two distinct traditions feeding into the moral philosophy of the seventeenth and eighteenth centuries. On the one hand, there is the empirical, naturalist tradition, comprising Hobbes, Locke, Cumberland, Hutcheson, and Hume, which argues that obligation is the practical force that empirical discoveries acquire in the process of deliberation. On the other hand, there is (...) a group including Cudworth, Shaftesbury, Butler, and in some moments Locke, which views obligation as inconceivable without autonomy and which seeks to develop a theory of the will as self-determining.

A substantial portion of Adam Smith's discussion of Stoicism in TMS VII is dedicated to the Stoic “principle of suicide,” according to which suicide is sometimes morally required. While scholars agree that Stoicism exercised considerable influence over Smith, no recent work has explored his views on suicide, despite the central role it plays in his treatment of Stoicism. I argue that Smith opposes the principle of suicide on both epistemic and moral grounds, providing an important critique of Stoicism. I also (...) show how Smith departs from other early modern accounts of suicide by offering a notably humane analysis of this tragic act. I conclude by considering what Smith's discussion of Stoicism and suicide tells us about his moral theory, and I forward a reading of Smith as a skeptic. (shrink)

The object of this paper is to show why recent research in the psychology of deductive and probabilistic reasoning does not have.

It is widely agreed among broadly Anselmian theists that God is in some sense the 'delimiter of possibilities.' In other words, the scope of possibility is explained by the manner in which the universe emanates from God. However, existing accounts of God's role here—in terms of freedom, choice, or power—face serious difficulties. The present paper provides a new account of God's role as the delimiter of possibilities in terms of the different manner in which the non-actuality of non-actual states of (...) affairs is explained. Intuitively and metaphorically, we can think of the menu of states of affairs being 'whittled down' in successive stages of a process of divine decision-making, with the different species of impossibility corresponding to when and how the states of affairs are ruled out. I argue that this approach provides genuine contingency while also preserving the Principle of Sufficient Reason. (shrink)

In lieu of an abstract, here is a brief excerpt of the content:Philosophy, Psychiatry, & Psychology 8.4 (2001) 317-322 [Access article in PDF] On Wolfgang Blankenburg, Common Sense, and Schizophrenia Aaron L. Mishara Introduction In its increasing openness to neuroscience (Cowan, Harter, and Kandel 2000) and other of its neighboring disciplines, mainstream biological psychiatry has allowed psychopathology, philosophy, and philosophical approaches to psychopathology to play an increased role in current research interests. Given this new openness, and the acknowledgment of the (...) severity of one of psychiatry's most debilitating, costly, and intractable disorders, 1 the translation of W. Blankenburg's 1969 article concerning the psychopathology of common sense does not merely serve historical interest. It is an exceptional example of a not well-known trend in German- and French-speaking psychiatry to apply philosophical phenomenology and existentialism to psychopathological research. This trend, which reached a peak in the late 1950s and was strong well into the 1970s, has dwindling, but nevertheless, current representatives in Heidelberg and Zurich and is scattered in a few other places in Europe, Japan, the United States, and South America. The view of the Zeitgeist—which may sound astonishing, even antiquated to contemporary readers—was highly ambitious: Conceptual approaches, such as philosophical ("transcendental") phenomenology, were expected to supply knowledge about the structure of consciousness and its disturbance in various mental disorders.Following the lead of Binswanger and Szilasi, who viewed schizophrenia as an "experiment of nature" that enables us to view underlying processes otherwise hidden to "natural, everyday consciousness," Blankenburg believed that it may be possible to map the formal properties of the psychopathology of schizophrenia—precisely in the loss of common sense—as a disturbance to the basic organization of conscious experience. Any attempt to summarize this rather abstract and complex approach in a brief commentary would be ill advised. In passing, rather, I will remark that such efforts could have profound relevance to the current research of schizophrenia and its underlying neurobiology. This research has gradually acknowledged the importance of taking the patient's subjective experience of the disorder into account (Mishara, Parnas, and Naudin 1998). In this commentary, I will first give an account of the biographical and clinical reasons that led Blankenburg to turn to the problem of common sense and its relevance for schizophrenia. I will then explore what implications [End Page 317] his work may have for more recent findings concerning schizophrenia. Blankenburg's Intellectual Development Born in 1928, W. Blankenburg, the son of a Lufthansa pilot who pioneered transatlantic commercial flights, began his studies in Freiburg im Breisgau in 1947. While at Freiburg, Blankenburg heard lectures in philosophy given by E. Fink (the former assistant to Husserl) and Max Mueller, and in psychology, by R. Heiss and others. After three years, Blankenburg turned to the study of medicine, producing a dissertation in 1956 on an application of Daseinsanalysis (Heidegger and Binswanger) to a case of paranoid schizophrenia. Binswanger wrote the forward to the publication. Between 1956 and 1958, Blankenburg studied internal medicine in Heidelberg with the accomplished phenomenologist of bodily experience (Leibphaenomenologer) and student of V. von Weizsaecker Herbert Pluegge. He spent one semester in Goettingen where he attended lectures by the ontological philosopher Nicolai Hartmann, who provided for Blankenburg a more useful approach to the problem of nature and natural science than Heidegger's primary emphasis on the question of Being. During his Freiburg years, Blankenburg attended small seminars led by Heidegger in the Schwarzwald forest. (Heidegger had been forbidden to teach after the end of World War II.) Blankenburg recalls that the participants would sit on logs in an open field as if to invoke Heidegger's concept of the clearing (Lichtung) of Being. While not entirely sympathetic with Heidegger's philosophy, Blankenburg learned to carefully "listen"—as Heidegger would repeatedly emphasize—to language, not merely poetic or philosophical language, but the language of the patients he would meet in clinical practice.During this time, Blankenburg heard lectures by W. Szilasi, the philosopher-scientist who held Husserl's and Heidegger's chair in the department of philosophy. Szilasi collaborated with the phenomenological psychiatrist, L. Binswanger. Their effort to apply concepts from Husserl's... (shrink)
