Defenders of the phenomenal concept strategy have to explain how both physical and phenomenal concepts provide a substantive grasp on the nature of their referents, whilst referring to the very same experience. This is the ‘new challenge’ to physicalism. In this paper, I argue that if the physicalist adopts the powerful qualities ontology of properties then a new and powerful version of the phenomenal concept strategy can be developed, which answers the new challenge.

I. Three Basic rights. This book is about the moral minimum--about the lower limits on tolerable human conduct, individual and institutional.

One of the most influential of the Victorian philosophers, Henry Sidgwick also made important contributions to fields such as economics, political theory, and classics. An active promoter of higher education for women, he founded Cambridge's Newnham College in 1871. He attended Rugby School and then Trinity College, Cambridge, where he remained his whole career. In 1859 he took up a lectureship in classics, and held this post for ten years. In 1869, he moved to a lectureship in moral philosophy, (...) the subject where he left arguably his greatest mark when he produced this work, regarded as his masterpiece. Published in 1874, the book argues the utilitarian approach to ethics, and a systematic and historically sensitive approach to ethical research that influenced utilitarian philosophers well into the twentieth century. It remains a valuable introduction to the philosophy, practice and history of ethics. This reissue includes the 1877 supplement. (shrink)

Background:Moral distress occurs when constraints prevent healthcare providers from acting in accordance with their core moral values to provide good patient care. The experience of moral distress in nurses might be magnified during the current Covid-19 pandemic.Objective:To explore causes of moral distress in nurses caring for Covid-19 patients and identify strategies to enhance their moral resiliency.Research design:A qualitative study using a qualitative content analysis of focus group discussions and in-depth interviews. We purposively sampled 31 nurses caring for Covid-19 patients in (...) the acute care units within large academic medical systems in Maryland and New York City during April to June 2020.Ethical considerations:We obtained approval from the Institutional Review Board at the University of Maryland, Baltimore.Results:We identified themes and sub-themes representative of major causes of moral distress in nurses caring Covid-19 patients. These included (a) lack of knowledge and uncertainty regarding how to treat a new illness; (b) being overwhelmed by the depth and breadth of the Covid-19 illness; (c) fear of exposure to the virus leading to suboptimal care; (d) adopting a team model of nursing care that caused intra-professional tensions and miscommunications; (e) policies to reduce viral transmission (visitation policy and PPE policy) that prevented nurses to assume their caring role; (f) practicing within crisis standards of care; and (g) dealing with medical resource scarcity. Participants discussed their coping mechanisms and suggested future strategies.Discussion/Conclusion:Our study affirms new causes of moral distress related to the Covid-19 pandemic. Institutions need to develop a supportive ethical climate that can restore nurses’ moral resiliency. Such a climate should include non-hierarchical interdisciplinary spaces where all providers can meet together as moral peers to discuss their experiences. (shrink)

In lieu of an abstract, here is a brief excerpt of the content:Learning to BreatheFive Fragments Against RacismB. Venkat Mani (bio)For Dr. JLW, for all Black academics and students1. Air HungerI know you, Derek Chauvin. You may think that we first met on May 25, 2020, in Minneapolis. I was called George Perry Floyd. For you, I was just another Black man, a potential criminal. For me, you were not a police officer, but the knee that stands for racism. (...) You kneeled on my windpipe for 9 minutes and 29 seconds. Those were neither my first nor my last memories.You may choose not to recognize me, as you always have. But I do. I recognize every bone, muscle, tendon, pointy curve of the cap, every contour of your strong, heavy, determined, calculating, conniving knee that presses on my windpipe with a false sense of racist superiority. 9 minutes and 29 seconds. As often as you can.We have a history. You have never missed the opportunity of kneeling on my windpipe. You hauled me into your slave ships from various African ports along the Atlantic, then you kneeled on my windpipe all over your cotton and tobacco plantations in the Americas. We met again on schooners from Indian shores journeying across the Indian and Pacific oceans. With slavery banned in the British empire, you turned me into an indentured laborer. You made me put my thumb imprint on a document you created, in a script I could not read, of a language I could not speak. Then you threw me thousands of miles away in Mauritius, Fiji, and numerous Caribbean islands, pressing on my windpipe on sugarcane plantations. My wife, children, sisters, mothers, aunts, brothers, uncles, nephews, nieces, grandparents, great grandparents, we all have lived through those fatal 9 minutes and 29 seconds: on water and land. Repeatedly. Consistently. Incessantly.You want specific dates? April 8, 1857, Barrackpore, Northern India. My name was Mangal Pandey, you called me a Sepoy. You hanged me for standing up against my subjugation by your British East India Company. Against your rule over my land and my people. With your many titles [End Page 41] and names: Major-General Sir Henry Havelock, Lieutenant-General Sir Colin Campbell, Brigadier-General Charles Windham, you rampaged through the streets of Delhi, Meerut, Lucknow, killing anyone in your way so I could be a jewel in Victoria's crown. January 29, 1863, Bear River, Idaho. I was one among the Shoshone of Bia Ogoi, you were Colonel Patrick Connor. You came to us on a frigid morning and killed us by the hundreds. November 15, 1884, the Congo Conference, Berlin. You were called Chancellor Otto von Bismarck and were acting at the behest of sharecropping interests of King Leopold the Second. Your name for me was a "savage." You set up a society to civilize me while you plundered my bounty. You started drawing lines through land, rivers, mountains, deserts. For you, it was the Scramble for Africa. For me, bloody murder. You knelt on my windpipe, smoking a pipe with tobacco my people had grown. April 13, 1919, Jallianwala Bagh, Amritsar. You were called Brigadier General Reginald Edward Harry Dyer. For you, I was just a troublemaking native disrupting the civilized business of the Empire. You surrounded our peaceful gathering in Amritsar and opened fire. Your Nobel Laureate Rudyard Kipling claimed that "you did your duty as you saw fit." By killing us in thousands until the bullets ran out. Rikki Tikki Tavi. May 31, 1921, Tulsa, Oklahoma. Inspired by Jim Crow, your knees came running to us in mobs to massacre us. October 19, 1926, Imperial Conference, London. Your name was Field Marshall the Right Honorable Jan Christian Smuts. For you, I was one among the many "colored" subjects from the Cape Colony. You spoke vehemently against mixing my people with your people. Eloquently, I was told, in favor of apartheid.You know very well, Chauvin, that our acquaintance neither begins in 1857 nor ends in 1926. I could take you on a grand tour of the world and give you all the dates when you appeared in different forms. Your self-induced conviction of racial supremacy over me remained the same... (shrink)

Since 1992, Border Crossings has show cased Henry A. Giroux's extraordinary range as a thinker by bringing together a series of essays that refigure the relationship between post-modernism, feminism, cultural studies and critical pedagogy. With discussions of topics including the struggle over academic canon, the role of popular culture in the curriculum and the cultural war the New Right has waged on schools, Giroux identified the most pressing issues facing critical educators at the turn of the century. In this (...) revised edition, Giroux reflects on the limits and possibilities of border crossings in the 21st century. "Borders" in our post 9/11 world have not been collapsing, he argues, but vigorously rebuilt. In order to have a truly critically engaged citizenry the challenges of these new "borders"- such as the increased militarization of public spaces, the rise of neo-liberalism, and the war in Iraq- must play a vital role in any debate on school and pedagogy.

A close look at the Jesuit and Catholic recusant network that existed in the English midlands yields a pathway to the Chandos portrait of Shakespeare. The portrait is traced from the 3rd Duke of Chandos to Grafton Manor, seat of the Shrewsbury earls and a principal Jesuit center in the Jesuit district comprising Worcestershire and Warwickshire created in 1623. The article finds that during Shakespeare’s lifetime, Grafton Manor was owned by a Catholic recusant member of the Talbot family with ownership (...) ties to Welbeck Abbey located in the small township of Holbeck, Nottinghamshire; the parish of Holbeck included Welbeck Abbey and the adjacent Holbeck Hall, which was owned by the family that sheltered Edmund Campion and which served later as home to a major Jesuit library and as a shelter for Jesuits themselves. Keeping in mind Shakespeare’s indebtedness to North family writings as source material for the plays, the article finds that the provenance of an unpublished manuscript by George North which influenced Shakespeare, the manuscript’s content, and George North’s circle of acquaintances lead directly to Edmund Campion and the Pierrepont family that sheltered him before his execution by the crown in 1581. The article shows ties of the George North manuscript to Welbeck Abbey, ties of the North family to the nearby Wroxton Abbey, and possible ties of the alleged painter of the Chandos portrait to the North family at Wroxton Abbey. The article is written in response to the recently published book by Dennis McCarthy and June Schlueter on the discovery of an unpublished manuscript written by George North that they believe inspired Shakespeare. Further shown through parallel language and thought that George North in writing A Brief Discourse likely drew material from Campion’s Histories of Ireland, including material that eventually led to the episodes on Jack Cade in 2 Henry VI and the Merlin prophecy in King Lear—all before Campion’s Histories was absorbed by Holinshed’s Chronicles and ultimately absorbed by Shakespeare. The article, utilizing research by an eminent Jesuit historian showing a personally advantageous relationship between George North’s patron, the Queen’s favored Sir Christopher Hatton, and the Jesuit William Crichton, traces the Shakespeare First Folio discovered on the Isle of Bute in 2016 back through time to the North family and ultimately to the Jesuit Crichton. In consideration of a probable biographical relationship between Shakespeare and Hatton, another connection between Shakespeare and the Jesuits is revealed. Lastly, the article details textual support for the author’s previous research showing a relationship between the writings of the Jesuit John Floyd and the Shakespearean canon—hinting that Shakespeare assisted the Jesuits.

Henry Richardson argues that we can determine our ends rationally. He constructs a rich and original theory of how we can reason about our final goals. Richardson defuses the counter-arguments for the limits of rational deliberation, and develops interesting ideas about how his model might be extended to interpersonal deliberation of ends, taking him to the borders of political theory. Along the way Richardson offers illuminating discussions of, inter alia, Aristotle, Aquinas, Sidgwick, and Dewey, as well as the work (...) of several contemporary philosophers. (shrink)

Henry S. Richardson is Professor of Philosophy at Georgetown University. From 2008-18, he was the editor of Ethics. His previous books include Practical Reasoning about Final Ends, Democratic Autonomy, and Moral Entanglements. He has held fellowships sponsored by the Alexander von Humboldt Foundation, the National Endowment for the Humanities, and the University Center for Human Values at Princeton University.

This book explains, in simple but accurate terms, how orthodox quantum mechanics works. The author, a distinguished theoretical physicist, shows how this theory, realistically interpreted, assigns an important role to our conscious free choices. Stapp claims that mainstream biology and neuroscience, despite nearly a century of quantum physics, still stick essentially to failed classical precepts in which mental intentions have no effect upon our bodily actions. He shows how quantum mechanics provides a rational basis for a better understanding of this (...) connection, even allowing an explanation of certain phenomena currently held to be "paranormal". These ideas have major implications for our understanding of ourselves and our mental processes, and thus also for the meaningfulness of our lives. (shrink)

Most people will grant that we bear special moral obligations toward at least some nonhuman animals that we do not bear toward inanimate objects like stones, mountains, or works of art. These moral obligations are plausibly grounded in the fact that many if not all nonhuman animals share important psychological states and capacities with us, such as consciousness, suffering, and goal-directed behavior. But which of these states and capacities are really critical for a creature’s possessing moral status, and how can (...) we determine which animals do in fact have them? In this paper, I examine three main approaches to answering these questions. First are what I term consciousness-based approaches that tackles these questions by first asking which animals are conscious. Second are affective-state approaches that focus on identifying behavioural and physiological signatures of states like pain, fear, and stress. Finally, I consider what I call preference-based approaches whose focus is on the question of which organisms have robust motivational states. I examine the prospects and challenges—both theoretical and empirical—faced by these seemingly contrasting methodologies. I go on to suggest that there are reasons why, despite challenges, we should be robustly committed to the project of identifying psychological grounds of moral status. I conclude by suggesting we should also take seriously the idea of pluralism about moral status, according to which each of these approaches might be capable of providing independent grounds for moral consideration.

BackgroundBiobanks have recently been established in several low- and middle-income countries in the Arab region of the Middle East. We aimed to explore the views of biobank managers regarding the challenges, ethical issues, and governance arrangements of their biobanks.MethodsIn-depth semi-structured qualitative interviews were conducted with a purposive sample of eight biobank managers from Egypt, Jordan, and Sudan. Interviews were performed either face-to-face, by phone, or via Zoom and lasted approximately 45–75 min. After verbal consent, interviews were recorded and then transcribed. (...) The authors performed a thematic analysis of the transcripts independently and then integrated the themes via a consensus process.ResultsBiobank managers discussed the main challenges in establishing their biobanks. These included the staff’s lack of experience and training, limited funds, deficit awareness of biobanks, obtaining funding from different sources. Only four reported they were active in distributing biospecimens and health data to researchers. Six biobanks used a broad consent model, one used tiered consent, and another allowed participants to opt-out of being recontacted. Five managers avoided partnerships with pharmaceutical companies due to concerns with unfavorable reactions from the community. Five managers did not have clear policies for returning research results to the donors. Five expressed challenges with sample and data sharing with international collaborators; all five used material transfer agreements. The biobank managers revealed variable governance arrangements and activities with community involving awareness and educational efforts rather than active engagement. Several expressed the importance of transparency with the operations of their biobanks and gaining the trust of their stakeholders.ConclusionManagers of biobanks in LMICs in the Arab Middle East encounter financial, operational, and social challenges toward their sustainability efforts. Discussions with key stakeholders are warranted to manage ethical issues involving informed consent, privacy, data sharing, and the return of results. We recommend that biobank managers in the Arab Middle East form collaborative networks within the region and internationally, develop trusting governance relationships with their stakeholders, and pursue engagement activities with their communities to enhance trust.

René Descartes proposed an interactive dualism that posits an interaction between the mind of a human being and some of the matter located in his or her brain. Isaac Newton subsequently formulated a physical theory based exclusively on the material/physical part of Descartes’ ontology. Newton’s theory enforced the principle of the causal closure of the physical, and the classical physics that grew out of it enforces this same principle. This classical theory purports to give, in principle, a complete deterministic account (...) of the physically described properties of nature, expressed exclusively in terms of these physically described properties themselves. Orthodox contemporary physical theory violates this principle in two separate ways. First, it injects random elements into the dynamics. Second, it allows, and also requires, abrupt probing actions that disrupt the mechanistically described evolution of the physically described systems. These probing actions are called Process 1 interventions by von Neumann. They are psycho-physical events. Neither the content nor the timing of these events is determined either by any known law, or by the afore-mentioned random elements. Orthodox quantum mechanics considers these events to be instigated by choices made by conscious agents. In von Neumann’s formulation of quantum theory each such intervention acts upon the state of the brain of some conscious agent.

I offer a new response to the regress argument against pure powers ontologies. This involves rejecting an overlooked premiss, which is that a power’s manifestation is exhaustively accounted for by the powers involved in it. Rejection of this premiss not only answers the regress argument, but also brings with it wider metaphysical consequences, including a shift away from one-category ontologies.

In our day-to-day lives, we form responsibility judgements about one another – but we are imperfect beings, and our judgments can be mistaken. This paper suggests that we get things wrong not merely by chance, but predictably and systematically. In particular, these miscues are common when we are dealing with large gaps in social status and power. That is, when we form judgements about those who are much more or less socially powerful than ourselves, it is increasingly likely that “epistemic (...) distorters” will reliably disrupt our reasoning. In response to this situation, I argue for the introduction of a new norm concerning blame and social status: “Powerful Restraint.” This norm suggests that the socially powerful ought to blame the socially dispossessed less frequently, and that social pressure be applied to achieve that compliance. I argue that such a norm is justified given the pernicious down-stream moral effects of the up-stream epistemic distortion I describe. I defend it against objections that it suggests a normative solution to an epistemic problem, that it is paternalistic, and that it involves a kind of disrespect to the less socially powerful.

Population-based genomics studies have proven successful in identifying genetic variants associated with diseases. High-quality biospecimens linked with informative health data from diverse segments of the population have made such research possible. However, the success of biobank research depends on the willingness of the public to participate in this type of research. We aimed to explore the factors associated with the willingness of the public to participate in biobank research from four low- and middle-income countries in the Arab region (Egypt, Jordan, (...) Morocco, and Sudan). We used a previously validated questionnaire to assess several constructs that included the public’s perceptions, attitudes, and willingness to participate in biobank research. We recruited 967 participants. More than half did not have prior awareness of biobanks. Participants’ willingness to donate biospecimens and health data was less than 10%. Our results also showed that participants harbored concerns with trust, privacy, and with data-sharing involving international researchers. Predictors of willingness to participate in biobank research included no previous involvement in research and positive attitudes toward biobanks. Finally, our study showed several differences between the four countries regarding several of the investigated constructs. We conclude there should be additional efforts to raise public awareness and enhance perceptions of the public in biobanking research to enhance trust. We further recommend qualitative research to explore the underlying factors that contribute to the public’s concerns with international data sharing that would enhance global health. (shrink)

A new research programme conceives of consciousness as a natural kind. One proposed virtue of this approach is that it can help resolve the methodological puzzle of consciousness, which involves distinguishing consciousness from cognitive access.

I argue that conceiving of consciousness as a natural kind cannot distinguish consciousness from (...) cognitive access. (shrink)

Despite there being little consensus on what intelligence is or how to measure it, the media and the public have become increasingly preoccupied with the concept owing to recent accomplishments in machine learning and research on artificial intelligence (AI). Governments and corporations are investing billions of dollars to fund researchers who are keen to produce an ever‐expanding range of artificial intelligent systems. More than 30 countries have announced such research initiatives over the past 3 years 1. For example, the EU (...) Commission pledged to increase the investment in AI research to €1.5 billion by 2020 (from €500 million in 2017), while China has committed $2.1 billion towards an AI technology park in Beijing alone 1. This global investment in AI is astonishing and prompts several questions: What are the true possibilities and limitations of AI? What do AI researchers and developers mean by “intelligence”? How does this compare to the everyday concept of intelligence and how the term is other branches of cognitive science? And can machine learning produce anything that is truly “intelligent”? (shrink)

This study considers the contribution of Francesco Patrizi da Cherso to the development of the concepts of void space and an infinite universe. Patrizi plays a greater role in the development of these concepts than any other single figure in the sixteenth century, and yet his work has been almost totally overlooked. I have outlined his views on space in terms of two major aspects of his philosophical attitude: on the one hand, he was a devoted Platonist and sought always (...) to establish Platonism, albeit his own version of it, as the only currect philosophy; and on the other hand, he was more determinedly anti-Aristotelian than any other philosopher at that time. Patrizi's concept of space has its beginnings in Platonic notions, but is extended and refined in the light of a vigorous critique of Aristotle's position. Finally, I consider the influence of Patrizi's ideas in the seventeenth century, when various thinkers are seeking to overthrow the Aristotelian concept of place and the equivalence of dimensionality with corporeality. Pierre Gassendi , for example, needed a coherent concept of void space in which his atoms could move, while Henry More sought to demonstrate the reality of incorporeal entities by reference to an incorporeal space. Both men could find the arguments they needed in Patrizi's comprehensive treatment of the subject. (shrink)

Quantum mechanical theories of consciousness are contrasted to classical ones. A key difference is that the quantum laws are fundamentally psychophysical and provide an explanation of the causal effect of conscious effort on neural processes, while the laws of classical physics, being purely physical, cannot. The quantum approach provides causal explanations, deduced from the laws of physics, of correlations found in psychology and in neuropsychology.

Experimental observations are often taken in order to assist in making a choice between relevant hypotheses ∼ H and H. The power of observations in this decision is here metrically defined by information-theoretic concepts and Bayes' theorem. The exact (or maximum power) of a new observation to increase or decrease Pr(H) the prior probability that H is true; the power of that observation to modify the total amount of uncertainty involved in the choice between ∼ H and H: the power (...) of a new observation to reduce uncertainty toward the ideal amount, zero; all these powers are systematically shown to be exact metrical functions of Pr(H) and Pr(o/H)/Pr(o)-1 where the numerator is the likelihood of the new observation given H, and the denominator is the "expectedness" of the observation.
