Connectionist models provide a promising alternative to the traditional computational approach that has for several decades dominated cognitive science and artificial intelligence, although the nature of connectionist models and their relation to symbol processing remains controversial. Connectionist models can be characterized by three general computational features: distinct layers of interconnected units, recursive rules for updating the strengths of the connections during learning, and “simple” homogeneous computing elements. Using just these three features one can construct surprisingly elegant and powerful models of (...) memory, perception, motor control, categorization, and reasoning. What makes the connectionist approach unique is not its variety of representational possibilities or its departure from explicit rule-based models, or even its preoccupation with the brain metaphor. Rather, it is that connectionist models can be used to explore systematically the complex interaction between learning and representation, as we try to demonstrate through the analysis of several large networks.

The field of neuroimaging has reached a watershed. Brain imaging research has been the source of many advances in cognitive neuroscience and cognitive science over the last decade, but recent critiques and emerging trends are raising foundational issues of methodology, measurement, and theory. Indeed, concerns over interpretation of brain maps have created serious controversies in social neuroscience, and, more important, point to a larger set of issues that lie at the heart of the entire brain mapping enterprise. In this volume, (...) leading scholars -- neuroimagers and philosophers of mind -- reexamine these central issues and explore current controversies that have arisen in cognitive science, cognitive neuroscience, computer science, and signal processing. The contributors address both statistical and dynamical analysis and modeling of neuroimaging data and interpretation, discussing localization, modularity, and neuroimagers' tacit assumptions about how these two phenomena are related; controversies over correlation of fMRI data and social attributions ; and the standard inferential design approach in neuroimaging. Finally, the contributors take a more philosophical perspective, considering the nature of measurement in brain imaging, and offer a framework for novel neuroimaging data structures.

The claims that learning systems must build causal models and provide explanations of their inferences are not new, and advocate a cognitive functionalism for artificial intelligence. This view conflates the relationships between implicit and explicit knowledge representation. We present recent evidence that neural networks do engage in model building, which is implicit, and cannot be dissociated from the learning process.

This article argues that teaching medical and nursing students health care ethics in an interdisciplinary setting is beneficial for them. Doing so produces an education that is theoretically more consistent with the goals of health care ethics, can help to reduce moral stress and burnout, and can improve patient care. Based on a literature review, theoretical arguments and individual observation, this article will show that the benefits of interdisciplinary education, specifically in ethics, outweigh the difficulties many schools may have in (...) developing such courses.

: In Engelhardt's secular bioethics, moral obligations derive from contracts and agreements between rational persons, and no infants or children and few adolescents meet Engelhardt's requirements for being a rational person. This is a problem, as one cannot have any direct secular moral obligations toward nonpersons such as infants and adolescents. The Engelhardtian concepts of ownership, indenture, and social personhood, which are meant to allow the theory to accommodate children and adolescents adequately, fail to give an Engelhardtian any actual means (...) of determining the right action to take in difficult cases, even on his or her own terms. Thus, the theory is incapable of determining the morally correct action to take in cases involving children and therefore is unhelpful in dealing with moral questions involving children. (shrink)

ABSTRACTTeam physicians have a complicated job that involves potentially conflicting obligations to multiple entities. Though responsible for the medical care of the athletes as individuals, they also have obligations to the team that employs them which can include returning athletes to play who are at heightened risk of re-injury. The fact that the athletes and owners have some overlapping interests only complicates this issue. Further, there are strong financial incentives to do what is necessary to obtain and keep a position (...) as a team physician. This article examines dual loyalty and conflict of interest in sports medicine, and argues that there is not now a widely accepted or adequate solution to either. Moving toward a solution will require fairly serious changes in the role of the team physician.Abbreviations: FIMS International Federation of Sports Medicine; NFL National Football League; MVP Most Valuable Player; RGIII Robert Griffin, III.

It is commonly assumed that persons who hold abortions to be generally impermissible must, for the same reasons, be opposed to embryonic stem cell research [ESR]. Yet a settled position against abortion does not necessarily direct one to reject that research. The difference in potentiality between the embryos used in ESR and embryos discussed in the abortion debate can make ESR acceptable even if one holds that abortion is impermissible. With regard to their potentiality, in vitro embryos are here argued (...) to be more morally similar to clonable somatic cells than they are to in vivo embryos. This creates an important moral distinction between embryos in vivo and in vitro. Attempts to refute this moral distinction, raised in the recent debate in this journal between Alfonso Gómez-Lobo and Mary Mahowald, are also addressed. (shrink)

The development of a code of ethics for a profession can be an indicator of the coherence and stability of a discipline as a unique and singular entity. Since “bioethics”, as a discipline, is not one profession but many, practiced by persons with not one but many varying responsibilities and training, it has been argued that no code of ethics is possible for the discipline(s) of bioethics. I argue that a code of ethics is possible for bioethics by looking at (...) the nature of the various disciplines and noting necessary overlap between them, and deriving the ethics from the nature of the discipline(s) themselves. I show how this can be done by arguing that strict rules about funding and conflict of interest are necessary for bioethicists. (shrink)

Makins’s analysis of the philosophical justification of decision-making understates and so misinterprets the importance of patient values to ‘the deference principle.’ (Makins N,1, p1) He assesses autonomy and beneficence as two separate arguments in support of deferring to patient preferences, but they only work well considered together. Further, neither the constitutive nor the evidential view of beneficence fully recognises the importance of patient values to understanding the patient’s worldview, which in turn determines what risks and benefits matter most. Revising these (...) arguments enables a much fuller understanding of the importance of patient values to the practice of medicine, which will in turn improve the refinement of the deference principle. Autonomy requires beneficence, and vice versa, for either of them to be sufficient arguments for deferring to patient choices. Focusing on autonomy alone to justify deference overstates the value of choice in and of itself, as good medicine does not pursue just any choices. It seeks informed consent, which means that the choices we truly value are those made while understanding what is importantly relevant to the choice. A well-informed decision includes data about expected side effects and likelihood of beneficial effects; but it also includes knowing the patient’s values and goals. One must know what is actually valuable …. (shrink)

An anxious resident paged ethics at 2:00 a.m. His patient, Mr. M, a twenty‐nine‐year‐old man with a history of multiple substance abuse, was in the hospital after cardiac arrest and lack of cerebral perfusion. Sadly, the young man probably met the criteria for brain death, but the final apnea test to confirm the diagnosis could not be done for another forty‐eight to seventy‐two hours because the Klonopin in his system might confound the results. The resident's concern, however, addressed a request (...) made by the patient's mother for a sperm harvest. The patient's mother maintained that her son had said he wanted to give her grandchildren. She wished to harvest sperm from him for a future use with an as‐yet‐to‐be‐determined surrogate mother. (shrink)

Jotkowitz, Glick, and Gesundheit (2008) rightly critique Manninen (2006) for an errant analysis of the Groningen protocol. However, they draw conclusions about the protocol itself that are not justified. Because of the nature of the care of infants, the Groningen protocol doesn't break new ethical ground. We already have to treat infants without direct access to their autonomous preferences or values; therefore, we are already making the decisions that Jotkowitz, Glick, and Gesundheit argue we are beginning to take once active (...) euthanasia of infants is allowed.

The study of perception and the role of the senses have recently risen to prominence in philosophy and are now a major area of study and research. However, the philosophical history of the senses remains a relatively neglected subject. Moving beyond the current philosophical canon, this outstanding collection offers a wide-ranging and diverse philosophical exploration of the senses, from the classical period to the present day. Written by a team of international contributors, it is divided into six parts: -/- Perception (...) from Non-Western Perspectives Perception in the Ancient Period Perception in the Medieval Latin/Arabic Period Perception in the Early Modern Period Perception in the Post-Kantian Period Perception in the Contemporary Period. The volume challenges conventional philosophical study of perception by covering a wide range of significant, as well as hitherto overlooked, topics, such as perceptual judgment, temporal and motion illusions, mirror and picture perception, animal senses and cross-modal integration. By investigating the history of the senses in thinkers such as Plotinus, Auriol, Berkeley and Cavendish; and considering the history of the senses in diverse philosophical traditions, including Chinese, Indian, Byzantine, Greek and Latin it brings a fresh approach to studying the history of philosophy itself. -/- Including a thorough introduction as well as introductions to each section by the editors, The Senses and the History of Philosophy is essential reading for students and researchers in the history of philosophy, perception, philosophy of mind, philosophical psychology, aesthetics and eastern and non-western philosophy. It will also be extremely useful for those in related disciplines such as psychology, religion, sociology, intellectual history and cognitive sciences. (shrink)

After people learn to sort objects into categories they see them differently. Members of the same category look more alike and members of different categories look more different. This phenomenon of within-category compression and between-category separation in similarity space is called categorical perception (CP). It is exhibited by human subjects, animals and neural net models. In backpropagation nets trained first to auto-associate 12 stimuli varying along a onedimensional continuum and then to sort them into 3 categories, CP arises as a (...) natural side-effect because of four factors: (1) Maximal interstimulus separation in hidden-unit space during autoassociation learning, (2) movement toward linear separability during categorization learning, (3) inverse-distance repulsive force exerted by the between-category boundary, and (4) the modulating effects of input iconicity, especially in interpolating CP to untrained regions of the continuum. Once similarity space has been "warped" in this way, the compressed and separated "chunks" have symbolic labels which could then be combined into symbol strings that constitute propositions about objects. The meanings of such symbolic representations would be "grounded" in the system's capacity to pick out from their sensory projections the object categories that the propositions were about. (shrink)

Sebbah’s noteworthy book is perhaps the first sustained inquiry into the relationship between three thinkers in the French phenomenological tradition, two of whom are well known in the Anglophone world (Levinas, Derrida) and one of whom (Henry) is gradually better understood by English-speaking audiences. That all three are arrayed together in this study makes it a pioneering enterprise and one that allows the English reader to apprise the worthiness of Henry’s association with his better-known compatriots.The strongest and most extensive portions (...) of the text focus on the three named figures in its subtitle, and in Part I Sebbah justifies his focus on these three in terms of a “family resemblance” (6–7) that they bear: Each in his own way practices phenomenology in the mode of excess, an excess that not only emerges in the style of each man’s writing but more fundamentally betrays a testing “of the limit, the limit through whose transgression alone excess can be what it is” (4).

In Patterns of Discovery, [1], and Concept of the Positron, [2], the late N. R. Hanson put forward an intersting and, I believe, essentially sound argument to the effect that, necessarily, micro-entities are "unpicturable." Hanson's claim is centrally a claim about microreduction, but his use of the term 'unpicturable' may be misleading, generating critiques which overplay its implications and its importance. A. M. Paul, in a recent article, [4], has taken Hanson to task in this regard, claiming (...) that the notion of picturability is so cloudy as to render Hanson's whole enterprise unconvincing. In what follows I shall critically discuss Hanson's argument and Paul's analysis and attempt to state a version of it capable of meeting Paul's objections. I will claim that Hanson's use of the term 'unpicturable' may be, at worst, infelicitous, and that his thesis concerning micro- or property-reduction remains unaffected by questions concerning what we can or cannot picture.

While in the movies or reading a novel, how can we feel terrified by monsters, ghosts, and fictional serial killers? And how can we feel sad or outraged by depictions of cruelty? After all, we know that the imagined threats that we fear do not exist and, therefore, pose no real threat to us; and we know that the instances of cruelty that bring tears to our eyes have not happened. And yet, the fear, the sadness, or the outrage experienced (...) in our imaginations feels very real. This is the so-called paradox of "fictional emotions." This and related paradoxes have become recalcitrant problems for a purely representational approach to the imagination that tries to accommodate the imagination in a belief-desire psychology, explaining our imaginings as mental states that are similar to beliefs or desires in some ways but not others—as "quasi-beliefs" or "quasi-desires." This representational approach can be seen, for example, in Kendall Walton's influential account of the imagination as "make-believe," or in Shaun Nichols and Stephen Stich's boxological account of the imagination as a "pretend box," which is in close interaction with the suspiciously similar "belief box".

In lieu of an abstract, here is a brief excerpt of the content:Reviewed by:A Pragmatist Philosophy of History by Marnie BinderPiers H. G. StephensA Pragmatist Philosophy of History Marnie Binder. Lexington Books, 2023.Looking at current scholarship and opinion in American philosophy, one can easily conclude that there has been much more work done on studying the history of pragmatist philosophy than there has been on what pragmatist philosophy can give to the study of history. Ever since the resurrection of interest (...) in pragmatism in the late twentieth century, we have seen a range of publications offering new interpretations for the ideas of the classical pragmatists, as well as important new applications for philosophical pragmatism and the moving to center stage of historically sidelined individuals and groups. What we have seen relatively little of, however, aside from a 2016 symposium in the European Journal of Pragmatism and American Philosophy, is sustained engagement with the question of what a classically pragmatist approach to historical inquiry might contribute, entail, or imply. It is this important niche in the ecosystem of American philosophy that Marnie Binder's A Pragmatist Philosophy of History seeks to partially fill in.Binder, who is perhaps best known for her past writings on José Ortega y Gasset, is at pains from the start to indicate both the humility and the utility of her project. As befits the tradition, there are no grandiose philosophical pretensions here, with the "goal in presenting a pragmatist philosophy of [End Page 112] history" merely being "to add another apparatus to the toolkits of the philosopher and the historian," an extra perspective that is "meant to complement other methodologies" (xi; emphasis in original), as she explains in her introduction. At the same time, pragmatism can offer something distinctive, firstly through asking the pragmatic question of what difference is meant by the accepting of particular presumed facts as being true, and secondly, being able to better understand why certain historical details have relevance, value, and meaning for us as a result of answering the first question. A pragmatist philosophy of history is helpful then, Binder maintains, as it "is in a unique position to bridge the speculative analytic divide" (xiii), and her approach to doing this is to draw upon the resources found in the works of a succession of the familiar classical pragmatists, building toward a synthesis and a cashing out of insights in her concluding reflections.Structurally the work consists of an explanatory introduction followed by six chapters, each dedicated to a particular pragmatist and their insights, leading finally to an extended concluding section drawing the component parts together and answering possible objections to the project. Pragmatism, as Binder recognizes, is seldom thought of as a historically orientated philosophy, but she argues that for each of these thinkers—William James, John Dewey, F. C. S. Schiller, Charles Sanders Peirce, George Herbert Mead, and Jane Addams—there is at least the germ of a philosophy of history that can be unearthed and developed, eventually helping to inform understanding of what is needed to bring a pragmatist ethics into practical reality, the last of which is manifested primarily by Addams. Thus, the treatment of William James in chapter 1 homes in on James's psychological insights into the way that experienced reality forms a temporal continuum; our consciousness necessarily selects from the experiences of the past, ascribing interpretations and assuming levels of facticity and relevance, since no individual can know all the facts or select among them with perfect impartiality. The continuum will be one that speaks to the inquirer's concerns with accuracy, practicality, meaningfulness, and coherence, as all knowledge comes about through temporal processes, and since past events are continuously added to and can be continuously reinterpreted, it can have no real or ultimate beginning or end. Accordingly, for a Jamesian pragmatist account, the "continuum of history is the way in which we construct a meaning for history of the connected past experiences with the present and in view of the future—this is what we call 'history'" (7; emphasis in original), and Binder draws upon José Medina's recent work to further illuminate how such history can and will be continuously critically reconstructed. In addition, she observes, such reconstruction [End Page... (shrink)

In a recent paper, T. R. Girill claims to have found some difficulties with an earlier paper of mine in which I argued, against A. M. Paul, that in principle, micro-entities are unpicturable. Paul had argued that N. R. Hanson's view, frequently repeated in Patterns of Discovery, to the effect that … atomic particles must lack certain properties; electrons could not be other than unpicturable. The impossibility of visualizing ultimate matter is an essential feature of atomic explanation.
