We give an account of some relationships between the principles of Constant and Atom Exchangeability and various generalizations of the Principle of Instantial Relevance within the framework of Inductive Logic. In particular we demonstrate some surprising and somewhat counterintuitive dependencies of these relationships on ostensibly unimportant parameters, such as the number of predicates in the overlying language.

The opinion of Mr. Justice Francis of the English High Court which denied the parents of Charlie Gard, who had been born with an extremely rare mutation of a genetic disease, the right to take their child to the United States for a proposed experimental treatment occasioned world wide attention including that of the Pope, President Trump, and the US Congress. The case raise anew a debate as old as the foundation of Western medicine on who should decide and on (...) what standard when there is a conflict between a family and the treating physicians over a possible treatment. This paper will explore the different approaches of the British and American courts on the issue and the various proposals from that of John Rawls in his A Theory of Justice to a processed-based approach for resolving such disputes. As carefully crafted as the opinion of Mr Justice Nicholas Francis in the Gard case proved to be, it left commentators unsatisfied. A widespread criticism, captured in an article by Michael Dougherty in The National Review was for the state to ‘get out of the way of the parents trying to act in the best interests of the child’.1 Although he conceded the parents could be adding to the suffering of the child by taking Charlie to America for an experimental therapy and agreed that such a choice ‘may be the wrong decision,’ in Dougherty’s view, it should still be ‘their decision’. Dougherty’s stand was the popular response to the question of ‘Who should decide?’ It fails, however, to propose any rationale for the decision. It provided no norms, no standards and no guidelines for the parents. Their motive could equally well be indifference to the suffering of the child as concern for his well-being. Furthermore, even good, loving parents may make …. (shrink)

IΣ n andBΣ n are well known fragments of first-order arithmetic with induction and collection forΣ n formulas respectively;IΣ n 0 andBΣ n 0 are their second-order counterparts. RCA0 is the well known fragment of second-order arithmetic with recursive comprehension;WKL 0 isRCA 0 plus weak König's lemma. We first strengthen Harrington's conservation result by showing thatWKL 0 +BΣ n 0 is Π 1 1 -conservative overRCA 0 +BΣ n 0 . Then we develop some model theory inWKL 0 and illustrate (...) the use of formalized model theory by giving a relatively simple proof of the fact thatIΣ 1 provesBΣ n+1 to be Π n+2-conservative overIΣ n . Finally, we present a proof-theoretic proof of the stronger fact that theΠ n+2 conservation result is provable already inIΔ 0 + superexp. ThusIΣ n+1 proves 1-Con (BΣ n+1) andIΔ 0 +superexp proves Con (IΣ n )↔Con(BΣ n+1). (shrink)

When there is a conflict between parents and the physician over appropriate care due to an infant whose decision prevails? What standard, if any, should guide such decisions?This article traces the varying standards articulated over the past three decades from the proposal in Duff and Campbell’s 1973 essay that these decisions are best left to the parents to the Baby Doe Regs of the 1980s which required every life that could be salvaged be continued. We conclude with support for the (...) policy articulated in the 2007 guidelines of the American Academy of Pediatrics on non-intervention or withdrawal of intensive care for high-risk newborns.

This volume investigates the role of the arts in character education. Bringing together insights from esteemed philosophers and educationalists, it looks to the arts for insight into human character and explores the arts' relationship to human flourishing and the development of the virtues. Focusing on the moral value of art and considering questions of whether there can be educational value in imaginative and non-narrative art, the nine chapters herein critically examine whether poetry, music, literature, films, television series, videogames, and even (...) gardening may improve our understanding of human character, sharpen our moral judgement, inculcate or refine certain skills required for virtue, or perhaps cultivate certain virtues themselves. Bringing together research on aesthetics, ethics, moral and character education, this book will appeal to students, researchers and academics of philosophy, arts, and education as well as philosophers of education, morality, aesthetics, and teachers of the arts.

With the purpose of introducing a useful tool for researches concerning foundations of quantum mechanics and applications to quantum technologies, here we address three quantumness quantifiers for bipartite optical systems: one is based on sub-shot-noise correlations, one is related to antibunching and one springs from entanglement determination. The specific cases of parametric downconversion seeded by thermal, coherent and squeezed states are discussed in detail.

During the first years of the post-war era, many French scientists travelled in the United States. As they looked for a reference to be used in rebuilding their own scientific landscape, their diaries say as much about the rise of the American biomedical complex as they do about their perception of research in the country. In order to illustrate how the French biologists adopted, competed with, or challenged the American model and how transatlantic exchanges played a critical role in the (...) molecularization of the life sciences, this paper presents three trajectories of laboratories. These include the services respectively led by P. Lepine and J. Monod at the Pasteur Institute, and G. Schapira's biochemical research unit at the Hopital des Enfants Malades. The three studies document the massive transatlantic circulation of materials, techniques, instruments, and people during the scientific reconstruction. The reconstruction however produced highly differentiated characters each operating in his own niche: the biotechnological inventor, the neo-clinician, and the fundamental biologist. The comparison situates the rise of molecular biology within the context of a rapidly expanding biomedical research system. It will help in understanding how, in contrast to the American situation, a logic of ''demedicalization'' became in France a means for developing biology at the molecular level. (shrink)
