Garrison's recent article provides another analysis of the need for the inclusion of a relativistic theoretical structure for doing psychological work that adopts some notion related to compementarity for integrating distinct relativistic positions. Problems in his historical account of the introduction of this approach are addressed. Issues concerned with interpretation by psychologists, including Garrison, of modern physical theory are also discussed and point toward the unique contribution that psychologists can bring to understanding modern physical theory. The central significance of psychologists' (...) exploration of modern physical theory is addressed through discussing evidence in this theory of an unavoidable link between the observing, thinking person and the physical world.

A straightforward explanation of fundamental tenets concerning the quantum mechanical wave function results in the thesis that the quantum mechanical wave function is a link between human cognition and the physical world. The way in which physicists have not accepted this explanation is discussed, and some of the roots of the problem are explored. The basis for an empirical test as to whether the wave function is a link between human cognition and the physical world is provided through developing an (...) experiment incorporating methodology from psychology and physics. Research in psychology and physics that relied on this methodology indicates that it is likely that Einstein, Podolsky, and Rosen's theoretical result that mutually exclusive wave functions can simultaneously apply to the same concrete physical circumstances can be implemented on an empirical level.

In their recent article, Kirsch and Hyland questioned the relation between psychological and associated neurophysiological phenomena in the introduction of complementarity into psychology. Mishkin's work on the neurophysiological basis of memory and perception provides an example of the extension of complementarity that I have proposed and that can serve as the basis for empirical testing of this extension. Mishkin's thesis that memory storage occurs at sensory stations in the cortex allows for the resolution of a fundamental problem in cognitive psychology, (...) namely the reciprocal dependence of perception and memory. Also, Mishkin's thesis allows that psychological phenomena do not depend on an objective world for their existence. (shrink)

Elitzur maintains that in quantum mechanical measurement consciousness does not have a significant impact on the physical world. His thesis is refuted through an elaboration of Schrödinger's gedankenexperiment called the cat paradox. The generally conservative tone of Elitzur's article as regards the involvement of consciousness in the physical world is discussed. Through discussing the conservation of energy and the second law of thermodynamics much differently than did Elitzur, it is shown how the involvement of human cognition in the functioning of (...) the physical world can be found in the structure of physical theory itself. Elitzur's major argument concerning a demonstration of a non-material basis for consciousness is shown to be inadequate. (shrink)

: This paper investigates the influence of Galileo's natural philosophy on the philosophical and methodological doctrines of Thomas Hobbes. In particular, I argue that what Hobbes took away from his encounter with Galileo was the fundamental idea that the world is a mechanical system in which everything can be understood in terms of mathematically-specifiable laws of motion. After tracing the history of Hobbes's encounters with Galilean science (through the "Welbeck group" connected with William Cavendish, earl of Newcastle and the "Mersenne (...) circle" in Paris), I argue that Hobbes's 1655 treatise De Corpore is deeply indebted to Galileo. More specifically, I show that Hobbes's mechanistic theory of mind owes a significant debt to Galileo while his treatment of the geometry of parabolic figures in chapter 16 of De Corpore was taken almost straight out of the account of accelerated motion Two New Sciences.

This paper deals with the very different attitudes that Descartes and Pascal had to the cycloid—the curve traced by the motion of a point on the periphery of a circle as the circle rolls across a right line. Descartes insisted that such a curve was merely mechanical and not truly geometric, and so was of no real mathematical interest. He nevertheless responded to enquiries from Mersenne, who posed the problems of determining its area and constructing its tangent. Pascal, in contrast, (...) saw the cycloid as a paradigm of geometric intelligibility, and he made it the focus of a series of challenge problems he posed to the mathematical world in 1658. After dealing with some of the history of the cycloid , I trace this difference in attitude to an underlying difference in the mathematical epistemologies of Descartes and Pascal. For Descartes, the truly geometric is that which can be expressed in terms of finite ratios between right lines, which in turn are expressible as closed polynomial equations. As Descartes pointed out, this means that ratios between straight and curved lines are not geometrically admissible, and curves that require them must be banished from geometry. Pascal, in contrast, thought that the scope of geometry included curves such as the cycloid, which are to be studied by employing infinitesimal methods and ratios between curved and straight lines.

Berkeley's philosophy has been much studied and discussed over the years, and a growing number of scholars have come to the realization that scientific and mathematical writings are an essential part of his philosophical enterprise. The aim of this volume is to present Berkeley's two most important scientific texts in a form which meets contemporary standards of scholarship while rendering them accessible to the modern reader. Although editions of both are contained in the fourth volume of the Works, these lack (...) adequate introductions and do not provide com plete and corrected texts. The present edition contains a complete and critically established text of both De Motu and The Analyst, in addi tion to a new translation of De Motu. The introductions and notes are designed to provide the background necessary for a full understanding of Berkeley's account of science and mathematics. Although these two texts are very different, they are united by a shared a concern with the work of Newton and Leibniz. Berkeley's De Motu deals extensively with Newton's Principia and Leibniz's Specimen Dynamicum, while The Analyst critiques both Leibnizian and Newto nian mathematics. Berkeley is commonly thought of as a successor to Locke or Malebranche, but as these works show he is also a successor to Newton and Leibniz. (shrink)

This is a dictionary of Descartes and Cartesian philosophy, primarily covering philosophy in the 17th century, with a chronology and biography of Descartes's life and times and a bibliography of primary and secondary works related to Descartes and to Cartesians.

Clinical ethics training programs are responsible for preparing their trainees to be competent ethics consultants worthy of the trust of patients, families, surrogates, and healthcare professionals. While the American Society for Bioethics and Humanities (ASBH) offers a certification examination for healthcare ethics consultants, no tools exist for the formal evaluation of ethics trainees to assess their progress toward competency. Medical specialties accredited by the Accreditation Council for Graduate Medical Education (ACGME) use milestones to report trainees’ progress along a continuum of (...) professional development as a means of “operationalizing and implementing” medical competencies. Utilizing the Core Competencies for Healthcare Ethics Consultation and the ACGME and American Board of Pediatrics’ (ABP) Pediatric Milestones Project, we developed milestones for 17 subcompetencies in clinical ethics consultation and academic bioethics. As the field of clinical ethics becomes more standardized, such tools will be needed to promote the development of robust training programs and to certify that their graduates are competent practitioners.

In the mid 1980s it was apparent that the need for organ donors exceeded those willing to donate. Some University of Pittsburgh Medical Center (UPMC) physicians initiated discussion of possible new organ donor categories including individuals pronounced dead by traditional cardiac criteria. However, they reached no conclusion and dropped the discussion. In the late 1980s and the early 1990s, four cases arose in which dying patients or their families requested organ donation following the elective removal of mechanical ventilation. Controversy surrounding (...) these cases precipitated open discussion of the use of organ donors pronounced dead on the basis of cardiac criteria. Prolonged deliberations by many committees in the absence of precedent ultimately resulted in what is, to our knowledge, the country's first policy for organ donation following elective removal of life support. The policy is intricate and conservative. Care was taken to include as many interested parties as possible in an effort to achieve representative and broad based support. This paper describes the development of the UPMC policy on non-heart-beating organ donation. (shrink)

When successful solid organ transplantation was initiated almost 40 years ago, its current success rate was not anticipated. But continuous efforts were undertaken to overcome the two major obstacles to success: injury caused by interrupting nutrient supply to the organ and rejection of the implanted organ by normal host defense mechanisms. Solutions have resulted from technologic medical advances, but also from using organs from different sources. Each potential solution has raised ethical concerns and has variably resulted in societal acclaim, censure, (...) and apathy. Transplant surgery is now well accepted, and the list of transplant candidates has grown far quicker than the availability of organs. More than 30,000 patients were awaiting organs for transplantation at the end of March 1993. While most organs came from donors declared dead by brain criteria, the increasing shortage of donated organs has prompted a reexamination of prior restrictions of donor groups. Recently, organ procurement from donors with cardiac death has been reintroduced in the United States. This practice had been mostly abandoned by the U.S. and some, though not all, other countries. Transplantation has been more successful using organs procured from heart-beating, "brain dead" cadavers than organs from non-heart-beating cadavers. However, recent advances have led to success rates with organs from non-heart-beating donors that may portend large increases in organ donation and procurement from this source. (shrink)

We introduce an innovative technique that quantifies human expertise development in such a way that humans and artificial systems can be directly compared. Using this technique we are able to highlight certain fundamental difficulties associated with the learning of a complex task that humans are still exceptionally better at than their computer counterparts. We demonstrate that expertise goes through significant developmental transitions that have previously been predicted but never explicated. The first signals the onset of a steady increase in global (...) awareness that begins surprisingly late in expertise acquisition. The second transition, reached by only a very few experts in the world, shows a major reorganisation of global contextual knowledge resulting in a relatively minor gain in skill. We are able to show that these empirical findings have consequences for our understanding of the way in which expertise acquisition may be modelled by learning in artificial intelligence systems. This point is emphasised with a novel theoretical result showing explicitly how our findings imply a non-trivial hurdle for learning for suitably complex tasks. (shrink)

Organ transplantation is an accepted therapy for major organ failure, but it depends on the availability of viable organs. Most organs transplanted in the U.S. come from either "brain-dead" or living related donors. Recently organ procurement from patients pronounced dead using cardiopulmonary criteria, so-called "non-heart-beating cadaver donors" (NHBCDs), has been reconsidered. In May 1992, the University of Pittsburgh Medical Center (UPMC) enacted a new, complicated policy for procuring organs from NHBCDs after the elective removal of life support. Seventeen months later (...) only one patient has become a NHBCD. This article describes her case and the results of interviews with the health care team and the patient's family. The case and interviews are discussed in relation to several of the ethical concerns previously raised about the policy, including potential conflicts of interest, the definition of cardiopulmonary death, and a possible net decrease in organ donation. The conclusion is reached that organ procurement from non-heart-beating cadavers is feasible and may be desirable both for the patient's family and the health care providers. (shrink)

We provide the first demonstration of an artificial neural network encoding the perceptual templates that form an important component of the high level strategic understanding developed by experts. Experts have a highly refined sense of knowing where to look, what information is important and what information to ignore. The conclusions these experts reach are of a higher quality and typically made in a shorter amount of time than those of non-experts. Understanding the manifestation of such abilities in terms of both (...) the psychology of expert performance and the underlying neural mechanisms constitutes one of the most challenging problems in the cognitive sciences. Using perceptual templates we show how the amount of contextual information can change significantly even within a given task, the relationship between local and non-local contexts and finally why there is very little correlation between measures of intelligence and level of expertise in many of the most complex tasks performed by humans.

In the preceding commentary, Campbell and Weber raise two valid and important issues concerning non-heart-beating organ donation (NHBOD). First, because the procedure links withdrawal of life support and the potential for subsequent organ donation, the desire for organs may create a situation in which care of the dying individual has relatively less importance and the dying may receive suboptimal care. Second, even if concerns about care of the dying were dealt with adequately, there will not be enough non-heart-beating donors to (...) significantly decrease the organ shortage that exists, making the procedure not worth the risk. We agree that attention to the important details of caring for the dying are, and must be, the primary concern of all health care workers caring for those individuals. Ensuring the patients' comfort, dignity, and autonomy, and providing for family and social support are the mainstays of this care. All policies for NHBOD should clearly support and mandate these concepts. Regarding the second concern, we agree that NHBOD is currently rare; however, evidence is increasing that this type of donation has great potential. Continued growth of the practice in this country will depend largely on public acceptance, which we believe will be directly influenced by whether the public perceives that care of the dying is not compromised by this procedure.

In 1991, the University of Pittsburgh Medical Center implemented a policy that permitted the recovery of organs from cadavers pronounced dead using standardized cardiac criteria. This policy allowed families that had made a decision to forgo life sustaining treatment to then request organ donation. This entailed taking the patient to the operating room, discontinuing therapy, and after the patient is pronounced dead, procuring organs.

The Edinburgh History of Distributed Cognition (Series Editor(s): Miranda Anderson, Douglas Cairns) -/- Questions the barriers between the humanities and the cognitive sciences. -/- Cognitive science is finding increasing evidence that cognition is distributed across brain, body and world. This series calls for a reappraisal of historical concepts of cognition in light of these findings. It engages with recent debates about the various strong or weak models of distributed cognition and brings them into discourse with research in the humanities. (...) Together, the books in this series give a wide-ranging examination of the parallels (and divergences) from these models in cultural, philosophical and scientific works, from antiquity to the mid-20th century. -/- Key Features: * Opens up our reading of Western European works in the fields of history of ideas, history of science, material culture and literary studies by bringing recent insights in cognitive science to bear on the distributed nature of cognition * Explores how sociocultural and environmental contexts lead to the manifestation of particular forms of cognitive paradigms or to their suppression * Traces the interconnections between and particular divergences across Western European history among the various concepts of distributed cognition -/- .

It distinguishes the many different types and methods of de-extinction. Finally, it examines the aims of wildlife conservation with a view to whether they are compatible with de-extinction, or not. -/- CHAPTER 2 examines three prime candidates for de-extinction—namely, the aurochs, the (...) woolly mammoth, and the passenger pigeon. It is about what these animals were like, why people want to resurrect them, and the methods by which their resurrections could be accomplished. -/- CHAPTER 3 is about the authenticity of de-extinct animals. Critics of de-extinction have offered many reasons for thinking that the products of de-extinction will be inauthentic. The bulk of the chapter is taken up with surveying their arguments. We attempt to show that none are convincing, and end the chapter by offering and defending two arguments in favour of the view that authentic de-extinctions are possible. -/- CHAPTER 4 surveys and critically evaluates all the main arguments both for and against de-extinction. It presents a qualified defence of the claim that conservationists should embrace de-extinction. It ends with a list of do’s and don’ts for conservationist de-extinction projects. (shrink)

This distinctive collection by scholars from around the world focuses upon the cultural, educational, and political significance of Richard Rorty's thought. The nine essays which comprise the collection examine a variety of related themes: Rorty's neopragmatism, his view of philosophy, his philosophy of education and culture, Rorty's comparison between Dewey and Foucault, his relation to postmodern theory, and, also his form of political liberalism.

Ethical consumption is on the rise, however little is known about the degree and the implications of the sometime conflicting sets of values held by the broad category of consumers who report consuming ethically. This paper explores convergence and divergence of ethical consumption values through a study of organic, fair trade, and local food consumers in Colorado. Using survey and focus group results, we first examine demographic and attitudinal correlates of ethical consumption. We then report evidence that while many organic, (...) fair trade, and local food consumers converge around similar values, some Colorado consumers support only local food, while opposing the consumption of organic and fair trade products. Next, we investigate how ethical consumers who converge and diverge frame their commitment to consuming ethically. The discussion and conclusion suggest that community development planners of projects that focus on ethical consumption will need to successfully traverse issues stemming from convergence and divergence to enjoy long-term sustained success.

Preprinted in God and the Problem of Evil (Blackwell 2001), ed. William Rowe. In this article, we reply to Bill Rowe's "Evil is Evidence Against Theistic Belief" in Contemporary Debates in Philosophy of Religion (Blackwell 2003).

Preprinted in God and the Problem of Evil(Blackwell 2001), ed. William Rowe. Many people deny that evil makes belief in atheism more reasonable for us than belief in theism. After all, they say, the grounds for belief in God are much better than the evidence for atheism, including the evidence provided by evil. We will not join their ranks on this occasion. Rather, we wish to consider the proposition that, setting aside grounds for belief in God and relying only on (...) the background knowledge shared in common by nontheists and theists, evil makes belief in atheism more reasonable for us than belief in theism. Our aim is to argue against this proposition. We recognize that in doing so, we face a formidable challenge. It’s one thing to say that evil presents a reason for atheism that is, ultimately, overridden by arguments for theism. It’s another to say that it doesn’t so much as provide us with a reason for atheism in the first place. In order to make this latter claim seem initially more plausible, consider the apparent design of the mammalian eye or the apparent fine-tuning of the universe to support life. These are often proposed as reasons to believe in theism. Critics commonly argue not merely that these supposed reasons for theism are overridden by arguments for atheism but rather that they aren’t good reasons for theism in the first place. Our parallel proposal with respect to evil and atheism is, initially at least, no less plausible than this proposal with respect to apparent design and theism. (shrink)
