In lieu of an abstract, here is a brief excerpt of the content:News from the President’s Council on BioethicsF. Daniel Davis (bio) and Diane M. Gianelli (bio)As most readers of this column already know, the President's Council on Bioethics went through a major transition during the past year when Leon Kass—in October 2005—handed the chairman's gavel over to Georgetown University's Edmund Pellegrino. Dr. Kass has remained on the Council as a member.1When the gavel change took place, the Council's phone (...) started ringing. Everyone wanted to know the same thing: What topics would the Council take up this term? Dr. Pellegrino's answer was always the same: The Council's agenda would be established through a consultative process with the members themselves and with an eye to those problems and controversies in bioethics to which we, as a body, can make a contribution.Taking its cue from the list of potential topics suggested by members, the Council—over the course of the next several meetings—listened to experts on such topics as children and bioethics (with a focus on children in clinical research), organ transplantation, and that oft-cited-but-hard-to-define concept, "human dignity."The latter topic entered the arena of discussion because it is a concept that is cited frequently in the bioethics literature, and it is also one that has figured prominently in Council discussions and documents. Although the concept is widely invoked, there is no universal understanding of what it means, and it is not easy to encapsulate into a one-size-fits-all definition. Indeed, some critics maintain that appeals to human dignity are fig leaves used to camouflage unconvincing arguments. So between December 2005 and April 2006, the Council devoted several sessions to various perspectives on "human dignity: its meaning, its foundations, and its relevance to bioethics." After hearing from James Childress, Patricia Churchland, Daniel Sulmasy, and Paul Weithman2 on the topic, the Council decided to issue a volume of approximately 20 essays, some by Council members and others by scholars from a variety of relevant disciplines.3 The volume is expected to encompass a broad array of opinion on the topic of human dignity and is scheduled to be published next spring."Children" were also the focus of several sessions during the past year. The Council's last report addressed care giving for the elderly.4 After it was issued, several members suggested it was time to focus on the youngest members of [End Page 375] society. The challenge, of course, was to find a topic that was both timely and relevant—and one about which the Council was uniquely qualified to make a contribution. A number of experts in a variety of related fields testified before the Council about possible issues it could explore: newborn screening for genetic disorders; decision-making standards for those who lack capacity; ethical issues in neonatal and pediatric intensive care; pharmacology and psychiatric disorders in children; and children and clinical research. In addition, a number of groups and individuals involved in related topics met with staff to discuss their interests and concerns.This exploratory engagement with facets of the broad topic of children and bioethics led the Council to focus, more narrowly, on a cluster of issues concerning newborn screening for genetic disorders—a topic on which it is likely that the Council will issue a white paper, possibly by next summer. The stimulus for this particular focus has been the American College of Medical Genetics's recommendation that all newborns in the U.S. be screened for a panel of 29 disorders.5 Currently, each state decides for its residents which conditions are subject to mandated screening, so it is possible to get early diagnoses of treatable disorders in one geographical area but not in another. Proponents of screening find the federal approach to mandated screening more equitable. Potential ethical problems, however, exist with the proposal. Some want to ensure that newborns are screened only for treatable conditions on grounds that it would be too burdensome to discover one is carrying the gene for a late-onset disease that cannot be prevented. Others want to make sure that insurance coverage for individuals and their families is... (shrink)

This study investigates the acquisition of integrated object manipulation and categorization abilities through a series of experiments in which human adults and artificial agents were asked to learn to manipulate two-dimensional objects that varied in shape, color, weight, and color intensity. The analysis of the obtained results and the comparison of the behavior displayed by human and artificial agents allowed us to identify the key role played by features affecting the agent/environment interaction, the relation between category and action development, and (...) the role of cognitive biases originating from previous knowledge.

The development of physical theory is one of our greatest intellectual achievements. Its products--the currently prevailing theories of physics, astronomy, and cosmology--have proved themselves to possess intrinsic beauty and to have enormous explanatory and predictive power. This anthology of primary readings chronicles the birth and maturation of five such theories (the heliocentric theory, the electromagnetic field theory, special and general relativity, quantum theory, and the big bang theory) in the words of the scientists who brought them to life. It is (...) the first historical account that captures the rich substance of these theories, each of which represents a fascinating story of the interplay of evidence and insight--and of dialogue among great minds. Readers sit in with Copernicus, Kepler, and Galileo as they overturn the geocentric universe; observe the genius of Faraday and Maxwell as they "discover" the electromagnetic field; look over Einstein's shoulder as he works out the details of relativity; listen in as Einstein and Bohr argue for the soul of quantum mechanics in the Completeness Debate; and watch as Hubble and others reveal the history of the universe. The editors' approach highlights the moments of discovery that rise from scientific creativity, and the presentation humanizes the scientific process, revealing the extent to which great scientists were the first to consider the philosophical implications of their work. But, most significantly, the editors offer this as their central thesis: although each was ushered in by a revolution, and each contains counterintuitive elements that delayed its acceptance, these five theories exhibit a continuous rational development that has led them to a permanent place in the worldview of science. Accessible to the general reader yet sufficiently substantive that working scientists will find value in it, The Tests of Time offers an intimate look into how physical theory has been developed, by the brilliant people who have developed it.

Since it was first published, Quantum Field Theory in a Nutshell has quickly established itself as the most accessible and comprehensive introduction to this profound and deeply fascinating area of theoretical physics. Now in this fully revised and expanded edition, A. Zee covers the latest advances while providing a solid conceptual foundation for students to build on, making this the most up-to-date and modern textbook on quantum field theory available. -/- This expanded edition features several additional chapters, as well as (...) an entirely new section describing recent developments in quantum field theory such as gravitational waves, the helicity spinor formalism, on-shell gluon scattering, recursion relations for amplitudes with complex momenta, and the hidden connection between Yang-Mills theory and Einstein gravity. Zee also provides added exercises, explanations, and examples, as well as detailed appendices, solutions to selected exercises, and suggestions for further reading. (shrink)

Concept of ethics in Ādi-Granth, Sikh canon.

At least for those who uphold the rationality of morality, ethics and practical reason are not two distinct topics: an ethically sound agent is one whose practical reason functions as it should. Take, for instance, the greatest historical figures. Aristotle claimed that no virtue of character can exist without practical wisdom—the excellence of practical, deliberative reason. And Kant thought that the categorical imperative, the ultimate moral principle that governs a good will, was at the same time the fundamental principlof practical (...) reasoning because the will simply ispractical reason. Even before any philosophical theory of the connection between acting well and the exercise of a rational power is in view, our moral practices strongly suggest that there is one. For we take it for granted that, in an important range of cases, when an agent fails to act as she should, something has gone awry with the agent and not just with her acts, and, furthermore, that the agent herself may be held responsible for this. In calling an agent who acts unethically "irrational," we are saying these two things. (shrink)

Upshot: We focus on the following issues: our intentions behind establishing the new Research Through Design conference series; epistemological concerns around “research through design”; and how we might find a balance between openness and specificity for the conference series going forward.

Estudio sistemático sobre la imagen y sus complejas relaciones con el lenguaje verbal, partiendo de una crítica al logocentrismo en su vertiente racionalista -que reduce el conocimiento y el pensamiento al discurso lingüístico- para desembocar en una teoría de la representación. El autor sostiene que la imagen va más allá de la representación al tornarse presencia, basándose en el examen de pensadores clásicos y teóricos actuales que han abordado cuestiones afines. Propone una teoría de la imagen que no se ciñe (...) sólo a lo visual, sino que reconoce las dimensiones no visuales de lo imaginal: "el principal objetivo de este libro es contribuir a la construcción de una filosofía de la imagen. Hoy en día es ya una necesidad urgente contar con un aparato conceptual que nos permita afrontar las distintas modalidades de lo imaginal, que aparecen en ámbitos tan diversos como la intimidad psicológica, la ciencia, la filosofía, la comunicación masiva, la religión, la educación, la propaganda o el arte".

I suppose the most obvious difference in fact between dreams and waking life is the chaotic nature of the former. But this somehow seems to be a mere contingency. Some of our dreams are more contingent than others, and it seems hard to impose any upper limit of coherence on them. Also it is usually after we wake up that they seem incoherent. Similarly many dreams are largely matters of sensation and emotion, mood and atmosphere, with little or no reasoning (...) in them; but this again is contingent, and dreams vary; Professor Broad, 56-57) relates a quite detailed scientific experiment which he carried out in a dream.
