Rare copy number variants have a prominent role in the aetiology of schizophrenia and other neuropsychiatric disorders. Substantial risk for schizophrenia is conferred by large CNVs at several loci, including microdeletions at 1q21.1, 3q29, 15q13.3 and 22q11.2 and microduplication at 16p11.2. However, these CNVs collectively account for a small fraction of cases, and the relevant genes and neurobiological mechanisms are not well understood. Here we performed a large two-stage genome-wide scan of rare CNVs and report the significant association of copy (...) number gains at chromosome 7q36.3 with schizophrenia. Microduplications with variable breakpoints occurred within a 362-kilobase region and were detected in 29 of 8,290 patients versus 2 of 7,431 controls in the combined sample. All duplications overlapped or were located within 89 kilobases upstream of the vasoactive intestinal peptide receptor gene VIPR2. VIPR2 transcription and cyclic-AMP signalling were significantly increased in cultured lymphocytes from patients with microduplications of 7q36.3. These findings implicate altered vasoactive intestinal peptide signalling in the pathogenesis of schizophrenia and indicate the VPAC2 receptor as a potential target for the development of new antipsychotic drugs. © 2011 Macmillan Publishers Limited.

The June 1975 issue of the Hastings Center Report published the Deliberations and Recommendations of the National Commission for the Protection of Human Subjects concerning the regulation of fetal experimentation. The Commission's most controversial conclusions were as follows: First, it voted to allow non‐therapeutic research on the human fetus, provided important biomedical knowledge could not be gained in any other way, proper consent had been obtained, and the research imposed “minimal or no risk to the well‐being of the fetus” (Recommendation (...) 4). Because interpretations of the last phrase varied in the case of fetuses scheduled for abortion, the Commission recommended that a national ethical review body be able to rule on disputed cases (Recommendation 5). In the case of research during abortion and research on the non‐viable fetus ex utero, the Commission's interpretation of permissible “harm” was restricted to the proviso that “no intrusion into the fetus [may be] made which alters the duration of life” (Recommendation 6). The Commission also recommended further research on abortion techniques (Recommendation 12). The Secretary of Health, Education and Welfare accepted the Commission's Recommendations almost without change—the major modification was to request paternal consent rather than to rely on the fact that “the father has not objected.” The DHEW regulations were published in the Federal Register on Friday, August 8, 1975, and written comments on them were invited. Already, however, a number of commentators including several members of the Commission had offered either dissenting or qualifying remarks. Some are printed here. (shrink)

Psychologists and philosophers often work hand in hand to investigate many aspects of moral cognition. In this paper, we want to highlight one aspect that to date has been relatively neglected: the stability of moral judgment over time. After explaining why philosophers and psychologists should consider stability and then surveying previous research, we will present the results of an original three-wave longitudinal study. We asked participants to make judgments about the same acts in a series of sacrificial dilemmas three times, (...) 6–8 days apart. In addition to investigating the stability of our participants’ ratings over time, we also explored some potential explanations for instability. To end, we will discuss these and other potential psychological sources of moral stability (or instability) and highlight possible philosophical implications of our findings. (shrink)

Recently, psychologists have explored moral concepts including obligation, blame, and ability. While little empirical work has studied the relationships among these concepts, philosophers have widely assumed such a relationship in the principle that “ought” implies “can,” which states that if someone ought to do something, then they must be able to do it. The cognitive underpinnings of these concepts are tested in the three experiments reported here. In Experiment 1, most participants judge that an agent ought to keep a promise (...) that he is unable to keep, but only when he is to blame for the inability. Experiment 2 shows that such “ought” judgments correlate with judgments of blame, rather than with judgments of the agent’s ability. Experiment 3 replicates these findings for moral “ought” judgments and finds that they do not hold for nonmoral “ought” judgments, such as what someone ought to do to fulfill their desires. These results together show that folk moral judgments do not conform to a widely assumed philosophical principle that “ought” implies “can.” Instead, judgments of blame play a modulatory role in some judgments of obligation.

We are happy to present the proceedings of the international symposium on Rationality and Religious Trust which were held at the University of Antwerp in this volume of Bijdragen. Rationality and religious trust is of course a topic that falls within the scope of the epistemology of religion. Contemporary epistemology of religion has been the scene of a vigorous debate about the nature of religious belief, or more precisely about the role of rationality and rational argument with respect to religious (...) belief. What is at stake in the debate, is the very way the concept of belief applies to the religious life. More specifically, the issue is about the place to be reserved for belief within the religious life at large, and again, about the role played especially by rational arguments in holding or not holding those beliefs.

The mechanical view on the human body may be considered as the context in which the highly technological medicine of these days originated. Organ transplantation is certainly one of the most impressive possibilities of this new evolution in medical technology. It exists by the grace of the paradigm of the body as a “Körper” : this paradigm leads to a self-evident acceptance of transplantation medicine in its most brilliant applications. Refinement of surgical techniques, better preservation of organs, the development of (...) more effective immunosuppressives, better procedures for the establishment of brain death criteria and better criteria for the selection and matching of donors and receptors are immanent goals of this type of medicine. Meanwhile the lives of many thousands of patients are saved and these patients even receive the chance for a new life, with much more quality. The ethical reflection on organ transplantation has followed rather rapidly this technical discourse and sounds as a kind of “moral engineering”. This is certainly connected with the upcoming success of “Principlism” , whereby medical decision making is oriented by applying four major principles to medical cases . It is also connected with the ethical approach of utilitarianism, which fits almost perfectly in this technological atmosphere. The authors question this approach and suggest that a more relational understanding of the human body as “Leib” would be a better paradigm for the promotion of solidarity in the context of organ donation and transplantation. Human beings do not only ‘have’ a body, but ‘are’ also their body. The body of the deceased refers to the life of a loved one. Technical procedures surrounding organ removals sometimes hinder the possibility for the family to bereave adequately around their loved one. The authors are convinced that the urging problem of organ shortage is not only caused by lack of solidarity or laziness, but also by the reductionist discourse of transplantation medicine itself. They suggest that we have to find – eventually with the help of poets and writers – an adequate new language to replace the alienating discourse of current transplantation medicine. They see also in communitarianism and personalist care ethics a better ethical approach for touching the peculiar sensitivities of eventual donors and receptors. (shrink)

People maintain a positive identity in at least two ways: They evaluate themselves more favorably than other people, and they judge themselves to be better now than they were in the past. Both strategies rely on autobiographical memories. The authors investigate the role of autobiographical memories of lying and emotional harm in maintaining a positive identity. For memories of lying to or emotionally harming others, participants judge their own actions as less morally wrong and less negative than those in which (...) other people lied to or emotionally harmed them. Furthermore, people judge those actions that happened further in the past to be more morally wrong than those that happened more recently. Finally, for periods of the past when they believed that they were very different people than they are now, participants judge their actions to be more morally wrong and more negative than those actions from periods of their pasts when they believed that they were very similar to who they are now. The authors discuss these findings in relation to theories about the function of autobiographical memory and moral cognition in constructing and perceiving the self over time. (shrink)

Albert Einstein’s bold assertion of the form invariance of the equation of a spherical light wave with respect to inertial frames of reference became, in the space of 6 years, the preferred foundation of his theory of relativity. Early on, however, Einstein’s universal light-sphere invariance was challenged on epistemological grounds by Henri Poincaré, who promoted an alternative demonstration of the foundations of relativity theory based on the notion of a light ellipsoid. A third figure of light, Hermann Minkowski’s lightcone also (...) provided a new means of envisioning the foundations of relativity. Drawing in part on archival sources, this paper shows how an informal, international group of physicists, mathematicians, and engineers, including Einstein, Paul Langevin, Poincaré, Hermann Minkowski, Ebenezer Cunningham, Harry Bateman, Otto Berg, Max Planck, Max von Laue, A. A. Robb, and Ludwig Silberstein, employed figures of light during the formative years of relativity theory in their discovery of the salient features of the relativistic worldview. (shrink)

: Originally presented during Ethic Rounds at the Dana-Farber Cancer Institute, this commentary on the case of a patient treated for life-threatening cancer explores the responsibilities of health care providers when addressing the patient's desire to adopt a child.

Is Goodness Without God Good Enough contains a lively debate between William Lane Craig and Paul Kurtz on the relationship between God and ethics, followed by seven new essays that both comment on the debate and advance the broader discussion of this important issue. Written in an accessible style by eminent scholars, this book will appeal to students and academics alike.

In the early days of organ transplantation from deceased donors, the surgical team would bring the donor into the operating room with the recipient, the respirator would be stopped, and the team would wait for the donor’s heart to cease beating. This type of organ donation has been defined as donation after cardiac death, also referred to as non-heart-beating donation. These donors were not declared dead using neurological criteria, but rather using conventional cardiorespiratory criteria. In 1959, Mollaret and Goulon coined (...) the term “coma dépassé” for the patients with an irreversible state of coma and apnea. Jean Morelle and Guy Alexandre of the Catholic University of Louvain, Belgium, were the first to introduce a set of brain death criteria based on the description of coma dépassé, and carried out, in 1963, the first transplants from a brain dead donor in their country and in the world.

Presumed consent alone will not solve the organ shortage, but it will create an ethical and legal context that supports organ donation, respects individuals who object to organ donation, relieves families from the burden of decision making, and can save lives.

The shortage of available organs for transplantation, organ tourism and illegal kidney transplantations put the question of paid organ donation and commercialism high on the agenda. Ethicists as J. Radcliffe-Richards and R.Veatch have reopened the debate. Therefore it is necessary and useful to check the main arguments pro and con. The advocates of paid organ donation refer to autonomy and pragmatic considerations. Why not regulate an ineradicable practice? The opponents rely on the dignity and integrity of the human body and (...) on justice. They are afraid of exploitation of the poor. A thorough analysis of the debate reveals that the arguments pro and con are incompatible and that the ethical debate leads nowhere. Furthermore, paid organ donation will stimulate the instrumentalisation and commodification of the human body. It brings about a further medicalisation of society where the wishes of the patient and the ‘cure’ prevails over the ‘care’, prevention of organ failure and scientific research . On the basis of the ethical impasse and especially on the basis of these implicit sociological considerations we make a plea against paid organ donation. Altruistic donation and solidarity must remain the basis of organ transplantation. Solidarity is fed by charity and fraternity , the two great sources of western culture and morality. These also must remain the basic inspiration of medicine in general and of organ transplantation in particular. (shrink)

Abstract:Vulnerability is an important criterion to assess the ethical justification of the inclusion of participants in research trials. Currently, vulnerability is often understood as an attribute inherent to a participant by nature of a diagnosed condition. Accordingly, a common ethical concern relates to the participant’s decisionmaking capacity and ability to provide free and informed consent. We propose an expanded view of vulnerability that moves beyond a focus on consent and the intrinsic attributes of participants. We offer specific suggestions for how (...) relational aspects and the dynamic features of vulnerability could be more fully captured in current discussions and research practices. (shrink)

For decades Darwinian processes were framed in the form of the Lewontin conditions: reproduction, variation and differential reproductive success were taken to be sufficient and necessary. Since Buss and the work of Maynard Smith and Szathmary biologists were eager to explain the major transitions from individuals to groups forming new individuals subject to Darwinian mechanisms themselves. Explanations that seek to explain the emergence of a new level of selection, however, cannot employ properties that would already have to exist on that (...) level for selection to take place. Recently, Hammerschmidt et al. provided a ‘bottom-up’ experiment corroborating much of the theoretical work Paul Rainey has done since 2003 on how cheats can play an important role in the emergence of new Darwinian individuals on a multicellular level. The aims of this paper are twofold. First, I argue for a conceptual shift in perspective from seeing cheats as a ‘problem’ that needs to be solved for multi-cellularity to evolve to the very ‘key’ for the evolution of multicellularity. Secondly, I illustrate the consequences of this shift for both theoretical and experimental work, arguing for a more prominent role of ecology and the multi-level selection framework within the debate then they currently occupy.

Darwin provided us with a powerful theoretical framework to explain the evolution of living systems. Natural selection alone, however, has sometimes been seen as insufficient to explain the emergence of new levels of selection. The problem is one of “circularity” for evolutionary explanations: how to explain the origins of Darwinian properties without already invoking their presence at the level they emerge. That is, how does evolution by natural selection commence in the first place? Recent results in experimental evolution suggest a (...) way forward: Paul Rainey and his collaborators have shown that Darwinian properties could be exogenously imposed via what they call “ecological scaffolding.” This could solve the “black box” dilemma faced by Darwinian explanations of new levels of organization. Yet, despite “scaffolding” recently becoming a popular term in the study of cognition, culture, and evolution, the concept has suffered from vagueness and ambiguity. This article aims to show that scaffolding can be turned into a proper scientific concept able to do explanatory work within the context of the major evolutionary transitions. Doing so will allow us to once again extend the scope of the Darwinian model of evolution by natural selection. (shrink)

This paper explores the relationship borne by the traditional paradoxes of set theory and semantics to formal incompleteness phenomena. A central tool is the application of the Arithmetized Completeness Theorem to systems of second-order arithmetic and set theory in which various “paradoxical notions” for first-order languages can be formalized. I will first discuss the setting in which this result was originally presented by Hilbert & Bernays (1939) and also how it was later adapted by Kreisel (1950) and Wang (1955) in (...) order to obtain formal undecidability results. A generalization of this method will then be presented whereby Russell’s paradox, a variant of Mirimanoff’s paradox, the Liar, and the Grelling–Nelson paradox may be uniformly transformed into incompleteness theorems. Some additional observations are then framed relating these results to the unification of the set theoretic and semantic paradoxes, the intensionality of arithmetization (in the sense of Feferman, 1960), and axiomatic theories of truth.

This is the first complete English translation of _On the Purity of the Art of Logic, _a handbook of logic written in Latin by English philosopher Walter Burley. The work circulated in the Middle Ages in two versions, a shorter and a longer one, both translated here by Paul Vincent Spade. The translations are based on the only complete edition of Burley’s treatises, corrected by Spade on the basis of one of the surviving manuscripts. The book also includes an (...) extensive introduction, explanatory notes, a table of corresponding passages between the two versions, a select annotated bibliography, and three indexes. A contemporary of John Duns Scotus and William of Ockham, Burley was active at the universities of both Paris and Oxford. He became one of the most important figures in the transformation of medieval logic and semantics that took place in the early fourteenth century. Burley used new tools and techniques of logical and semantical analysis, yet in many cases he used them in defense of traditional views, such as a realist metaphysical theory of “universals_._”_ On the Purity of the Art of Logic_ shows_ _both these sides of Burley—the innovator and the conservative—as well as some of the ways in which his views corresponded or clashed with those of William of Ockham.

Pretendo igualmente refletir sobre o papel da tradição cristã nas leis e na política a partir da perspectiva da justiça.

This thought-provoking book initiates a dialogue among scholars in rhetoric and hermeneutics in many areas of the humanities. Twenty leading thinkers explore the ways these two powerful disciplines inform each other and influence a wide variety of intellectual fields. Walter Jost and Michael J. Hyde organize pivotal topics in rhetoric and hermeneutics with originality and coherence, dividing their book into four sections: Locating the Disciplines; Inventions and Applications; Arguments and Narratives; and Civic Discourse and Critical Theory. Contributors to this volume (...) include Hans-Georg Gadamer, Paul Ricoeur, Gerald L. Bruns, Charles Altieri, Richard E. Palmer, Calvin O. Schrag,.Victoria Kahn, Eugene Garver, Michael Leff, Nancy S. Streuver, Wendy Olmsted, David Tracy, Donald G. Marshall, Allen Scult, Rita Copeland, William Rehg, and Steven Mailloux. For readers across the humanities, the book demonstrates the usefulness of rhetorical and hermeneutic approaches in literary, philosophical, legal, religious, and political thinking. With its stimulating new perspectives on the revival and interrelation of both rhetoric and hermeneutics, this collection is sure to serve as a benchmark for years to come. (shrink)

Reagan mixes the genres of biographical essay, memoir, philosophical essay, and interview to provide the reader with a fascinating and highly readable account. The biographical essay narrates Ricoeur’s early life, his experience as a POW during the Second World War, professorships at the Sorbonne, Nanterre, and Chicago, and his “rediscovery” in and return to France after the publication of Time and Narrative. Reagan’s analysis betrays Ricoeur’s comment that “no one is interested in my life... [since] my life is my work... (...) my books and my articles.” Ricoeur’s captivity as a prisoner of war, the problems he encountered at Nanterre University as doyen of the Faculty of Letters during the 1960s, and the pain and love he and Simone felt for Olivier, their fourth child who committed suicide, are some of the intriguing and touching elements of the narrative. After Olivier’s tragic death in 1986, Ricoeur added “suffering” to the phrase “human action” whenever he wrote about the problem of human action and suffering. (shrink)

In 1969, the field of human genetics was in its infancy. Amniocentesis was a new technique for prenatal diagnosis, and a newborn genetic screening program had been established in one state. There were also concerns about the potential hazards of genetic engineering. A research group at the Hastings Center and Paul Ramsey pioneered in the discussion of genetics and bioethics. Two principal techniques have emerged as being of enduring importance: human gene transfer research and genetic testing and screening. This (...) essay tracks the development and use of these techniques and considers the ethical issues that they raise. (shrink)

Two arguments Paul Snowdon has brought against the causal theory of perception are examined. One involves the claim that, based on the phenomenology of perceptual situations, it cannot be the case that perception is an essentially causal concept. The other is a reductio , according to which causal theorists’ arguments imply that a proposition Snowdon takes to be obviously non-causal ( A is married to B ) can be analyzed into some sort of indefinite ‘spousal connection’ plus a causal (...) ingredient . I conclude that neither argument is sound. The reason that Snowdon’s critiques fail is that, since causal theories need not be about ‘effect ends’ that are internally manifest to perceivers, no such ostensibly separable, non-causal property as it being to S as if he were perceiving O need be an essential element in a causal theory of perception.

Dr. Ron Paul, leader of the libertarian movement and former Congressman, favors the elimination of the death penalty. He argues from both a moral and economic, or pragmatic, perspective against executions. The present article takes issue with his stance and defends the killing of convicted murderers, with some caveats.

This paper argues that Burley's theory of simple supposition is not as it has usually been presented. The prevailing view is that Burley and other authors agreed that simple supposition was in every case supposition for a universal, and that the disagreement over simple supposition between, say, Ockham and Burley was merely a disagreement over what a universal was (a piece of the ontology? a concept?), combined with a separate disagreement over what terms signify (the speaker's thoughts? the objects the (...) thoughts are about?).In fact, however, Burley explicitly allows that some instances of simple supposition are for an individual, and that in certain cases personal supposition and simple supposition coincide. The present paper explores Burley's theory on this topic, and proposes a way of thinking about the metaphysics and the semantics that makes sense of what he says. (shrink)

The history of the mediaeval obligationes-literature has only recently begun to be studied. Two important treatises in this literature, one by Walter Burley and the other attributed to William of Sherwood, have been edited by Romuald Green in a forthcoming book.

The correct attribution and dating of this treatise is crucial for our understanding of the history of this literature. In this paper, we argue that the (...) treatise is not as early as William of Sherwood, that on the contrary it dates no earlier than the very end of the thirteenth century, and that, although there is some contrary evidence, the treatise may be an early work by Walter Burley himself.
