By mass-energy equivalence, the gravitational field has a relativistic mass density proportional to its energy density. I seek to better understand this mass of the gravitational field by asking whether it plays three traditional roles of mass: the role in conservation of mass, the inertial role, and the role as source for gravitation. The difficult case of general relativity is compared to the more straightforward cases of Newtonian gravity and electromagnetism by way of gravitoelectromagnetism, an intermediate theory of gravity that (...) resembles electromagnetism.

"As a distinctive philosophy, religious humanism emphasizes man's place in an unfathomed universe, reason as an instrument for discovering the truth, free inquiry as a condition for discerning meaning and purpose, and happiness as a fundamental value. "Man's uniqueness emerges partly from homo sapiens' capacity to employ symbols effectively. For this reason, Willard's provocative book is not a celebration of controversy but a sophisticated study exploring the grounds of man's knowledge. Drawing upon phenomenologists such as Alfred Schultz, psychologists such as (...) George Kelley, and argumentation philosophers such as Stephen Toulmin, Willard makes a genuine contribution to intellectual inquiry by extending essential consideration about human knowledge. The [author] demonstrates how 'secular sources' provide a fundamental resource in developing religious understanding from argumentative interactions. "Highly insightful and intellectually refreshing... _Argumentation and the Social Grounds of Knowledge_ provides thought-provoking reading for humanists concerned with rational inquiry, communication theory, religious philosophy, and liberal education." _--Religious Humanism_.

Are they needed? To be sure. The Darwinian industry, industrious though it is, has failed to provide texts of more than a handful of Darwin's books. If you want to know what Darwin said about barnacles (still an essential reference to cirripedists, apart from any historical importance) you are forced to search shelves, or wait while someone does it for you; some have been in print for a century; various reprints have appeared and since vanished." -Eric Korn,Times Literary Supplement (...) class='Hi'>Charles Robert Darwin (1880-1882) has been widely recognized since his own time as one of the most influential writers in the history of Western thought. His books were widely read by specialists and the general public, and his influence had been extended by almost continuous public debate over the last 130 years. New York University Press' edition makes it possible for the first time to review Darwin's public literary output as a whole, plus his scientific journal articles, his private notebooks, and his correspondence. This is the first complete edition containing all of Darwin's published books, featuring definitive texts recording original paginations with Darwin's indexes retained. All illustrations and plates are presented, inclucing 82 color plates of birds and mammals and several folding maps and plates. The set also features a general introduction and index, and textural introductions in each volume. (shrink)

Yang returns to the problem of referential ambiguity, addressed in the opening paper by Gleitman and Trueswell. Using a computational approach, he argues that “big data” approaches to resolving referential ambiguity are destined to fail, because of the inevitable computational explosion needed to keep track of contextual associations present when a word is uttered. Yang tests several computational models, two of which depend on one‐trial learning, as described in Gleitman and Trueswell’s paper. He concludes that such models outperform cross‐situational learning (...) models, thereby formalizing, reinforcing, and advancing the conclusions offered by Gleitman and Trueswell. (shrink)

Should engineering ethics be taught? Despite the obvious truism that we all want our students to be moral engineers who practice virtuous professional behavior, I argue, in this article that the question itself obscures several ambiguities that prompt preliminary resolution. Upon clarification of these ambiguities, and an attempt to delineate key issues that make the question a philosophically interesting one, I conclude that engineering ethics not only should not, but cannot, be taught if we understand “teaching engineering ethics” to mean (...) training engineers to be moral individuals (as some advocates seem to have proposed). However, I also conclude that there is a justification to teaching engineering ethics, insofar as we are able to clearly identify the most desirable and efficacious pedagogical approach to the subject area, which I propose to be a case study-based format that utilizes the principle of human cognitive pattern recognition.

Interaction between Peter Singer and Christian ethics, to the extent that it has happened at all, has been unproductive and often antagonistic. Singer sees himself as leading a 'Copernican Revolution' against a sanctity of life ethic, while many Christians associate his work with a 'culture of death'. Charles Camosy shows that this polarized understanding of the two positions is a mistake. While their conclusions about abortion and euthanasia may differ, there is surprising overlap in Christian and Singerite arguments, and (...) disagreements are interesting and fruitful. Furthermore, it turns out that Christians and Singerites can even make common cause, for instance in matters such as global poverty and the dignity of non-human animals. Peter Singer and Christian ethics are far closer than almost anyone has imagined, and this book is valuable to those who are interested in fresh thinking about the relationship between religious and secular ethics.

English translation, with Chinese source text, of a seminal Chinese classic.

John Dewey once said of philosophical problems that they are quite different from old soldiers. Not only do they never die, but they do not even fade away. Something similar might be said about the unfavourable Divine attributes of the 1950s and 60s, timelessness or eternity, necessary existence, foreknowledge of creaturely free choices, and immutability. All have contemporary defenders. Even the puzzling, traditional tenet that God is metaphysically simple now has formidable apologists. Perhaps the least popular of the traditional theistic (...) canon, the most likely to fade away, is the tenet that God is impassible. The recent appearance of Richard Creel's Divine Impassibility has shown that even this least popular of attributes can be powerfully articulated and defended. Roughly, the impassibility thesis is the claim that God does not undergo sensory experience including suffering and pain, nor is God subject to corruption, substantial essential change or to external agency. Creel's defence of Divine impassibilism is certainly the most balanced and sophisticated in the current literature. Any argument for passibilism must take Creel's work seriously. I intend to do just that in the course of defending the thesis that the God of Christian theism is passible in an important respect. There are substantive moral and religious reasons to believe God suffers. (shrink)

In lieu of an abstract, here is a brief excerpt of the content:"The Crowd Is Untruth": A Comparison of Kierkegaard and Girard Charles K. Bellinger University of Virginia The purpose ofthis essay is to provide an introductory comparison of the writings of Soren Kierkegaard and René Girard. To my knowledge, a substantial secondary article or book has not been written on this subject.1 Girard's writings themselves contain only a handful of references to Kierkegaard.2 This deficiency is unfortunate, since, as (...) I hope to show in the following pages, these two authors do share common insights into the psychology ofviolence. Girard's writings usually take the form of a scientific analysis of historical data. He is attempting to frame a theory of culture which takes into account all of the data which he has encountered. It would seem that Kierkegaard's mode of thought is very different, since he is primarily concerned with the meaning of personal existence before God. But 1 Eugene Webb's Philosophers of Consciousness and The Self Between contain discussions ofKierkegaard and Girard, but they are basically parallel sections which do not include a focused comparison of the two authors. David McCracken's The Scandal ofthe Gospels makes reference to Girard and contains a chapter on Kierkegaard, but it also lacks an extended comparison. 2 See Girard 1984, 58; 1986, 173; 1988, 26-7. In his Foreword to Robert HamertonKelly (xi), Girard says, "Mimetic theory is too realistic and commonsensical to be confused with one more nihilistic stepchild ofGerman idealism. And yet, unlike the positivistic social sciences, it is not blind to paradox; it can articulate the intricacies of human relations just as effectively as a Kierkegaard or a Dostoievsky." 104Charles K Bellinger Kierkegaard was in his own way and in his own time a kind of social scientist. He engaged in an extended "anthropological contemplation" (1967-1978, 1:37), in which he attempted to map out the territory of the human spirit. Girard's thought, for its part, occasionally steps outside ofthe methodological atheism of the scientific guild to speak in theological terms. Thus in both realms, the scientific and the theological, there is the possibility of fruitful dialogue between these two authors. I am assuming that the readers ofthis essay are more familiar with the writings of Girard than with the writings of Kierkegaard. My procedure will therefore involve listing certain key concepts in Girard's thought, such as mimetic desire, envy, the social crisis, etc., followed by a search for parallel ideas in Kierkegaard. IfGirard were claiming complete originality for his interpretation of culture, my findings would show that he was in many respects foreshadowed by Kierkegaard. But, of course, he is not claiming this. He claims only to be restating and organizing insights which have already been achieved by great novelists and the Bible. I would argue that Kierkegaard is rightly seen as one of the great "novelists" who sees human culture clearly and penetratingly. It is not a coincidence that Kierkegaard's thought, like Girard's, is rooted in an interpretation ofthe Bible. After this initial survey ofsimilarities between Kierkegaard and Girard, I will outline a few possible differences between their approaches. This will lead to comments on the way in which Kierkegaard's thought can be used as a basis for understanding the motives which underlie political violence. Consequently Kierkegaard's thought can be coordinated with Girard's in such a way that the thought ofeach author is strengthened by the contribution of the other. Mimetic desire Mimetic desire is the main starting point for Girard's theory of personality and culture. Human beings have a basic feeling ofexistential lack that leads them to look to a model who seems to possess a greater fullness of being. The desires of the model are imitated in the hope of acquiring a similar fullness ofbeing. In Girard's words: When modem theorists envisage man as a being who knows what he wants, or who at least possesses an "unconscious" that knows for him, they may simply have failed to perceive the domain in which human uncertainty is most extreme. Once his Kierkegaard and Girard105 basic needs are satisfied (indeed, sometimes even before), man is subject to intense desires, though he may not... (shrink)

"In Getting Even, Charles Barton contends that revenge can be a form of justice that is constructive and healing for our society. Our current judiciary system, he explains, denies both victims and the accused an active role in the legal proceedings and resolution of their cases, reducing them to bystanders in what is essentially their own conflict. Barton does not argue for an individual's right to take the law into his own hands, but does show that the courts should (...) recognize the revenge motive as legitimate and rational within the rules of justice."--pub. desc.

This volume sets Berkeley's philosophy in its historical context by providing selections from: firstly, works that deeply influenced Berkeley as he formed his main doctrines; secondly, works that illuminate the philosophical climate in which those doctrines were formed; and thirdly, works that display Berkeley's subsequent philosophical influence. The first category is represented by selections from Descartes, Malebranche, Bayle, and Locke; the second category includes extracts from such thinkers as Regius, Lanion, Arnauld, Lee, and Norris; while reactions to Berkeley, both positive (...) and negative, are drawn from a wide range of thinkers - Leibniz, Baxter, Hume, Diderot, Voltaire, Reid, Kant, Herder, and Mill.

The observed complexity of nature is often attributed to an intrinsic propensity of matter to self-organize under certain (e.g., dissipative) conditions. In order better to understand and test this vague thesis, we define complexity as “logical depth,” a notion based on algorithmic information and computational time complexity. Informally, logical depth is the number of steps in the deductive or causal path connecting a thing with its plausible origin. We then assess the effects of dissipation, noise, and spatial and other symmetries (...) of the initial conditions and equations of motion on the asymptotic complexity-generating abilities of statistical-mechanical model systems. We concentrate on discrete, spatially-homogeneous, locally-interacting systems such as kinetic Ising models and cellular automata. (shrink)

Most contemporary philosophers who defend the compatibility of hell with the divine goodness do so by arguing that the damned freely choose hell. Thomas Talbott denies that such a choice is possible, on the grounds that God in his goodness would remove any 'ignorance, deception, or bondage to desire' which would motivate a person to choose eternal misery. My strategy is to turn the tables on Talbott and ask why God would not remove the motives we have for any sin (...) whatsoever. I argue that two plausible answers to this question also show why God would not remove our motives for choosing hell. (shrink)

The Mississippi River flows through American history and culture as a mythic waterway brimming with tragedy and hope, and awash in passionate ambitions and harsh realities. In 1953, a young Charles Dee Sharp traveled twice down the Mississippi to make a documentary film of it, taking black-and-white photographs of the river, its communities, and its people. While Sharp’s documentary never came to fruition, the striking images he captured survived as moving and evocative historical testaments to a lost era, now (...) collected in his new book The Mississippi in 1953. These images create a vivid portrait of America’s heartland a half century ago, and they are enriched with excerpts from Sharp’s original trip journal, intriguing anecdotes from the people he encountered along his journey, and an engaging environmental history of the river by historian John O. Anfinson. The Mississippi in 1953 offers an original and poignant look at the living artery of the American landscape and how it molded the United States into the nation it is today. (shrink)

Plato's striking figure of the ‘child in us’ at Phaedo 77e5 takes on an added lustre when viewed in the light of the theory of explanation Socrates develops between lOObl and 105c7.Socrates' theory aims to explain why certain objects have certain properties: why something is beautiful or tall, or when a body will be sick or alive. Explanation is called for, Socrates thinks, when an object has a property its title to which is insecure, in the sense that the object's (...) having the property is not guaranteed by its being what it is. Thus Socrates wants an explanation, for example, of a person's being tall or – the case of especial interest in the Phaedo – of a body's being alive. (shrink)

The COVID-19 pandemic touched off an unprecedented search for vaccines and treatments. Without question, the development of vaccines to prevent COVID-19 was an enormous scientific accomplishment. Further, the RECOVERY and Solidarity trials identified effective treatments for COVID-19. But all was not success. The urgent need for COVID-19 prevention and treatment fueled an embrace of risks—to research participants and to the reliability of the science itself—as allegedly necessary costs to speed scientific progress. Scientists and (even) ethicists supported overturning longstanding norms protecting (...) healthy volunteers in human challenge trials to speed vaccine development, but these trials led to no vaccines. Physicians, with the approval of research ethics committees, designed hundreds of unblinded, single-center clinical trials at high risk of bias to speed the identification of new treatments. But these clinical trials led to no treatments. The lesson for future pandemics is that the acceptance of greater risks to participants or science does not reliably lead to progress. We are better served by science that upholds the highest ethical and methodological standards. (shrink)

In this issue ofJME, Watsonet alcall for research evaluation of government health programmes and identify ethical guidance, including the Ottawa Statement on the ethical design and conduct of cluster randomised trials, as a hindrance. While cluster randomised trials of health programmes as a whole should be evaluated by research ethics committees (RECs), Watsonet alargue that the health programme per se is not within the researcher’s control or responsibility and, thus, is out of scope for ethics review. We argue that this (...) view is wrong. The scope of research ethics review is not defined by researcher control or responsibility, but rather by the protection of research participants. And the randomised evaluation of health programmes impacts the liberty and welfare interests of participants insofar as they may be exposed to a harmful programme or denied access to a beneficial one. Further, Watsonet al’s claim that ‘study programmes … would occur whether or not there were any … research activities’ is incorrect in the case of cluster randomised designs. In a cluster randomised trial, the government does not implement a programme as usual. Rather, researchers collaborate with the government to randomise clusters to intervention or control conditions in order to rigorously evaluate the programme. As a result, equipoise issues are triggered that must be addressed by the REC. (shrink)

The three claims put forward by Dr. Roger Poisson to rationalize his enrollment of ineligible subjects in clinical trials do not justify research fraud. None the less, certain lessons for the conduct of clinical research can be learned from the affair: experimental therapies should be made available to technically ineligible subjects when no effective therapy exists for their disease; further research must investigate the possible benefits of clinical-trial participation; broadly based, pragmatic trials must be regarded as the ideal model; and (...) each eligibility criterion in a clinical-trial protocol should be justified.
