In this interview, James L. McClelland responds to questions regarding connectionist models of cognition, a theory inspired by information processing in the brain. McClelland explains the distinction between symbolic and non-symbolic processing for a better understanding of mental processes. He argues that connectionist models can perform the computations which we know the brain can perform. In addition, he responds to several general questions on the perspectives of computational models of cognition.

Abstract:Disturbing cases continue to be published of patients declared brain dead who later were found to have a few intact brain functions. We address the reasons for the mismatch between the whole-brain criterion and brain death tests, and suggest solutions. Many of the cases result from diagnostic errors in brain death determination. Others probably result from a tiny amount of residual blood flow to the brain despite intracranial circulatory arrest. Strategies to lessen the mismatch include improving brain death determination training (...) for physicians, mandating a test showing complete intracranial circulatory arrest, or revising the whole-brain criterion.

The publicity surrounding the recent McMath and Muñoz cases has rekindled public interest in brain death: the familiar term for human death determination by showing the irreversible cessation of clinical brain functions. The concept of brain death was developed decades ago to permit withdrawal of therapy in hopeless cases and to permit organ donation. It has become widely established medical practice, and laws permit it in all U.S. jurisdictions. Brain death has a biophilosophical justification as a standard for determining human (...) death but remains poorly understood by the public and by health professionals. The current controversies over brain death are largely restricted to the academy, but some practitioners express ambivalence over whether brain death is equivalent to human death. Brain death remains an accepted and sound concept, but more work is necessary to establish its biophilosophical justification and to educate health professionals and the public. (shrink)

Organ donation after the circulatory determination of death requires the permanent cessation of circulation while organ donation after the brain determination of death requires the irreversible cessation of brain functions. The unified brain-based determination of death connects the brain and circulatory death criteria for circulatory death determination in organ donation as follows: permanent cessation of systemic circulation causes permanent cessation of brain circulation which causes permanent cessation of brain perfusion which causes permanent cessation of brain function. The relevant circulation that (...) must cease in circulatory death determination is that to the brain. Eliminating brain circulation from the donor ECMO organ perfusion circuit in thoracoabdominal NRP protocols satisfies the unified brain-based determination of death but only if the complete cessation of brain circulation can be proved. Despite its medical and physiologic rationale, the unified brain-based determination of death remains inconsistent with the Uniform Determination of Death Act. (shrink)

Anthropology is a complex, wide-ranging, and ever changing field. Yet, despite its diversity, certain major themes do occur in the understandings of the world that anthropologists have offered. In this clear, coherent, and well-crafted book, James L. Peacock spells out the central concepts, distinctive methodologies, and philosophical as well as practical issues of cultural anthropology. Designed to supplement standard textbooks and monographs, the book focuses on the premises that underlie the facts that the former kinds of works generally present. (...) Free from unnecessarily abstract theoretical language and based on compelling concrete anecdote and engaging illustration, it is written in terms understandable to the anthropological novice, as well as being of value to the professional. The book's three main concerns are the substance, method, and significance of anthropology. In his discussion of substance, method, and significance of anthropology, such as the concept of culture, as well as holism. In writing about method, he explores the distinctive character of ethnographic fieldwork and raises questions of interpretation and comparison. Finally, he considers the relevance of anthropology with respect to both its practical application and what it contributes to understanding of human affairs. Using the photographic metaphors of 'harsh light' and 'soft focus', Peacock characterizes the anthropological worldview as consisting of two elements: on the one hand, a concern with the basic reality of the human condition, free of cultural influence; on the other, a broadly based holism that attempts to grasp all aspects of that condition, including its relation to the anthropologist. His book will appeal widely to readers interested in anthropology, at all levels. (shrink)

Thomas Hurka has recently proposed a utilitarian theory which would effect a compromise between Average and Total utilitarianism, the better to deal with issues in population ethics. This Compromise theory would incorporate the principle that the value which an extra happy person contributes to a possible world is a decreasing function of the total population of that world: that happy people are of diminishing marginal value. In spite of its initial plausibility I argue against this principle. I show that the (...) Compromise theory is actually no improvement over the two original versions of utilitarianism; in particular, it is subject to almost all the objections which are fatal to Average utilitarianism, and more besides. And I attempt to dispell the appearance that intuition supports the Compromise theory as against Total utilitarianism, by arguing that the latter's Repugnant Conclusion, when properly understood, is not intuitively unacceptable. Total utilitarianism remains a plausible ethical theory, while both the Average and the Compromise theories should be definitely rejected. (shrink)

The overall purpose of this paper is to clarify the physical meaning and epistemological status of the term 'measurement' as used in quantum theory. After a review of the essential logical structure of quantum physics, Part I presents interpretive discussions contrasting the quantal concepts observable and ensemble with their classical ancestors along the lines of Margenau's latency theory. Against this background various popular ideas concerning the nature of quantum measurement are critically surveyed. The analysis reveals that, in addition to internal (...) mathematical difficulties, all the so-called quantum theories of measurement are grounded in unjustifiable, classical presuppositions.

Over the past quarter century, organ donation after the circulatory determination of death (DCD) has grown in acceptance and prevalence throughout the world (Domínguez-Gil et al. 2021). Notwithstan...

Despite the popularity, success, and growth of programs of organ donation after the circulatory determination of death (DCDD), a long‐standing controversy persists over whether the organ donor is truly dead at the moment physicians declare death, usually following five minutes of circulatory and respiratory arrest. Advocates of the prevailing death determination standard claim that the donor is dead when declared because of permanent cessation of respiration and circulation. Critics of this standard argue that while the cessation of respiration and circulation (...) may be permanent, it may not be irreversible at the moment death is declared because, if cardiopulmonary resuscitation were performed, it might succeed. And because irreversibility of cessation of respiration and circulation is required by both the statute and the biological concept of death, the donor must be alive. Who is correct?Making two related distinctions clarifies the cause of the disagreement over whether the DCDD donor is dead and points to a possible resolution. First, in a determination of death, there is an important distinction between the permanent and the irreversible cessation of circulation and respiration—two associated phenomena that are often confounded. Second, there is an important distinction between the medical practice standard for death determination, in which physicians certify the permanent cessation of vital functions as sufficient for death declaration, and the underlying biological concept of death that requires the irreversible cessation of vital functions because death, by definition, is an irreversible event.

Among the old and new controversies over brain death, none is more fundamental than whether brain death is equivalent to the biological phenomenon of human death. Here, I defend this equivalency by offering a brief conceptual justification for this view of brain death, a subject that Andrew Huang and I recently analyzed elsewhere in greater detail. My defense of the concept of brain death has evolved since Bernard Gert, Charles Culver, and I first addressed it in 1981, a development that (...) paralleled advances in intensive care unit treatment. The century‐old concept of the organism as a whole provides the fundamental justification for the equivalency of brain death and human death. In our technological age, in which increasing numbers of components and systems of an organism can be kept alive, and for longer intervals, the permanent cessation of functioning of the organism as a whole is the phenomenon that best corresponds to its death.

Expressivists about normative thought and discourse traditionally deny that there are nondeflationary normative propositions. However, it has recently been suggested that expressivists might avoid a number of problems by providing a theory of normative propositions compatible with expressivism. This paper explores the prospects for developing an expressivist theory of propositions within the framework of cognitive act theories of propositions. First, I argue that the only extant expressivist theory of cognitive propositions—Michael Ridge's ‘ecumenical expressivist’ theory—fails to explain identity conditions for normative (...) propositions. Second, I argue that this failure motivates a general constraint—the ‘unity requirement’—that any expressivist theory of propositions must provide a unified nonrepresentational explanation of that in virtue of which propositional attitudes have the content that they have. Third, I argue that conceptual role accounts of content provide a promising framework in which to develop an expressivist theory of cognitive propositions. (shrink)

The “greatness” of the Mahābhārata, its mahat/mahā quality, refers primarily to its intended dynamism as a powerful engine generating the spread of Brahminic teaching throughout the world, casting “heathen” (nāstika) teachings and their patrons into shadow for all time. The Brahmin authors worked to accomplish this end in two main ways. First, they devised a tremendously engaging tale that depicted the decisive victory of a king (Yudhiṣṭhira Pāṇḍava) who accepted Brahmin claims to deserve monopoly-control over teaching the norms of society. (...) Second, they made this tale an extensive magisterium of Brahmin ideology and philosophy, affording to all in society, women and śūdras as well as Aryan men, encouragement to seek the forgiveness of past wrongs at tīrthas and access to the teachings of mokṣa without Vedic initiation.

This portion of the essay concludes a two-part paper, Part I of which appeared in an earlier issue of this Journal. Part II begins with a careful study of the quantum description of real experiments in order to motivate a proposal that two distinct quantum theoretical measurement constructs should be recognized, both of which must be distinguished from the concept of preparation. The different epistemological roles of these concepts are compared and explained. It is then concluded that the only possible (...) type of "quantum measurement theory" is one of little metaphysical interest and that quantum measurement seems problematical only when viewed from an overly narrow classical perspective.

In lieu of an abstract, here is a brief excerpt of the content:Philosophy and Rhetoric 35.2 (2002) 138-152 [Access article in PDF] Respecting the Rupture: Not Solving the Problem of Unity in Plato's Phaedrus James L. Kastely Plato's Phaedrus is a particularly instructive example of the double nature and status of rhetoric, for it embodies a tension at the heart of rhetoric. The first half of the dialogue presents three examples of rhetorical practice, while the second develops a theoretical (...) justification of rhetoric as an art. Thus, the dialogue would seem to offer a productive negotiation of the practice/theory tension. What makes the dialogue interesting, however, is the fact that this negotiation does not occur. The dialogue does not bring theory and practice into a harmonious relation, for there is a troubling discontinuity between its two halves, and rhetorical practice feels fractured. The exploration of eros that had occupied the first half of the dialogue is abandoned before the beginning of the second half, and then, following a logic that is at best associational, Socrates and Phaedrus explore the standards that should govern the practice of rhetoric. The infelicity of this transition raises a question: why did Plato structure the Phaedrus in such a way that it emphasized the dissonance between the two halves of the dialogue? To pose the question this way, however, is to go in a direction different from many of the best contemporary interpretations of the dialogue, which either argue that the dialogue is unified (Griswold 164) or suggest that the dissonance between its two halves reflects a shift in Plato's approach to philosophy (Kahn 373; Nehamas 352). In contrast, I will argue that the rupture in the dialogue is thematically purposive, for it points to an inescapable schism within rhetoric that makes rhetoric philosophically interesting.Socrates' second speech, his palinode to Eros, is a rhetorical tour de force that closes the first half of the dialogue. The importance of the palinode, however, is not limited to its role as an exemplary rhetorical performance, [End Page 138] for it also plays a crucial role in resolving the problem of erotic madness that organizes the intellectual drama of the first half. It would seem reasonable to expect that such an important and powerful moment in the dialogue would, at the very least, play a significant role in the philosophical discussion that composes the dialogue's second half. But that doesn't happen. While Socrates does refer to the palinode in his theoretical discussion of rhetoric, he makes little use of it, and, more important, he is silent on the subject of eros. Both the dramatic organization of the second half of the dialogue and its theoretical discussion cooperate to turn the rhetorical triumph of the palinode into a problem. Why has eros been abandoned as a philosophic topic, and what does this abandoning imply about the erotically grounded rhetoric that Socrates practiced and defended?To make matters worse, Socrates himself dismisses the palinode as a serious effort. He characterizes the speech as little more than a pleasant game, one that is not without value only because "these two certain forms (of gathering and dividing) were stated by chance" (265c). Far from viewing the palinode as possessing philosophical significance, Socrates appears to value it principally for its being a so-so example of a work of rhetoric that has been shaped by dialectic. While it is hard not to take Socrates' dismissal of the seriousness of the speech as partially disingenuous (just prior to his dismissal, he refers to the palinode as serious and reverent [265b]), he also does seem to mean what he says. Whether he is being straightforward or ironic does not finally matter because in either case the problem that occupies him and Phaedrus in the first half has disappeared from the dialogue. And that creates a problem: for if the philosophic issues of the first half of the dialogue drop out, then the dialogue is not coherent.This incoherence is especially troubling given Socrates' explicit endorsement of coherence as an important rhetorical value. In fact, when he begins his... (shrink)

The study of human intelligence was once dominated by symbolic approaches, but over the last 30 years an alternative approach has arisen. Symbols and processes that operate on them are often seen today as approximate characterizations of the emergent consequences of sub- or nonsymbolic processes, and a wide range of constructs in cognitive science can be understood as emergents. These include representational constructs (units, structures, rules), architectural constructs (central executive, declarative memory), and developmental processes and outcomes (stages, sensitive periods, neurocognitive (...) modules, developmental disorders). The greatest achievements of human cognition may be largely emergent phenomena. It remains a challenge for the future to learn more about how these greatest achievements arise and to emulate them in artificial systems. (shrink)

The question whether epistemological concepts are closed under deduction is an important one since many skeptical arguments depend on closure. Such skepticism can be avoided if closure is not true of knowledge (or justification). This response to skepticism is rejected by Peter Klein and others. Klein argues that closure is true, and that far from providing the skeptic with a powerful weapon for undermining our knowledge, it provides a tool for attacking the skeptic directly. This paper examines various arguments in (...) favor of closure and Klein's attempted use of closure to refute skepticism. Such a refutation of skepticism is mistaken. But the closure principle is in any case false, so the skepticism that depends on it is undermined. The appeal of the closure principle derives from a failure to recognize an important feature of our epistemological concepts, namely, their context relativity. (shrink)

This paper compares the preface of Columella’s Res rustica with that of the earliest fully extant Chinese agricultural treatise, the Qimin yaoshu (‘Essential Techniques for the Common People’) of Jia Sixie. I argue that both prefaces have a similar function: to present to the reader the social world in which the author wishes his agricultural work to be understood. By drawing on authoritative literary and historical traditions, each author projects an idealized vision of farming in which the discipline acquires a (...) deep moral significance. Granting these striking similarities, the authors’ views also diverge in certain illuminating respects: these include the moral agency of agriculture, the social location of expertise, and the historical development of agriculture in relation to society.

Scepticism about ought simpliciter is the view that there is no such thing as what one ought simpliciter to do. Instead, practical deliberation is governed by a plurality of normative standpoints, each authoritative from their own perspective but none authoritative simpliciter. This paper aims to resist such scepticism. After setting out the challenge in general terms, I argue that scepticism can be resisted by rejecting a key assumption in the sceptic’s argument. This is the assumption that standpoint-relative ought judgments bring (...) with them a commitment to act in accordance with those judgments. Instead, I propose an alternative account of our normative concepts according to which only ought simpliciter judgments commit one to acting in accordance with those judgments. In addition to answering the sceptical challenge, the proposal offers an independently motivated account of what makes a concept normatively authoritative. (shrink)

The reasoning view of rational normativity claims that structural rationality is normative for reasoning. Specifically, it claims that structural rationality gives us reasons to structure deliberation in ways that respect the requirements of rationality. This paper critically assesses the reasoning view. It argues that while the reasoning view might succeed in responding to arguments against the normativity of rationality, it is in tension with the motivations for thinking that rationality is normative in the first place. Moreover, proponents of the view (...) do not offer any independent reason for thinking that the view is true. As such, we have no reason to accept the reasoning view. (shrink)

One response to the chronic shortage of organs for transplant in the United States has been the passage of laws establishing first-person authorization for donation of organs, providing legal grounds for the retrieval of organs and tissues from registered donors, even over the objections of their next of kin. The ethical justification for first-person authorization is that it is a matter of respecting the donor’s wishes. The objection of some next of kin may be that the donor would not have (...) wished for his or her loved ones to have their preferences overridden, had they considered that possibility. This article examines the basis of the conflict and suggests a remedy grounded in the provision of donor-intent options that have the ability to clarify the donor’s wishes. (shrink)

This book supports the emerging field of vascularized composite allotransplantation for face and upper-limb transplants by providing a revised, ethically appropriate consent model which takes into account what is actually required of facial and upper extremity transplant recipients. In place of consent as permission-giving, waiver, or autonomous authorization, this book imagines consent as an ongoing mutual commitment, i.e. as covenant consent. The covenant consent model highlights the need for a durable personal relationship between the patient/subject and the care provider/researcher. Such (...) a relationship is crucial given the recovery period of 5 years or more for VCA recipients. The case for covenant consent is made by first examining the field of vascularized composite allotransplantation, the history and present understandings of consent in health care, and the history and use of the covenant concept from its origins through its applications to health care ethics today. This book explains how standard approaches to consent are inadequate in light of the particular features of facial and upper limb transplantation. In contrast, use of the covenant concept creates a consent model that is more appropriate ethically for these very complex surgeries and long-term recoveries. (shrink)

The introduction by Merold Westphal sets the scene: "Two books, two visions of philosophy, two friends and sometimes colleagues...". Modernity and Its Discontents is a debate between Caputo and Marsh in which each upheld their opposing philosphical positions by critical modernism and post-modernism. The book opens with a critique of each debater of the other's previous work. With its passionate point-counterpoint form, the book recalls the philosphical dialogues of classical times, but the writing style remains lucid and uncluttered. Taking the (...) failure of Englightenment ideals as their common ground, the debaters challenge each other's ideas on the nature of post-foundationalist critique. At the core of the argument lies the timely question of the role that each person can play in creating a truly humane society. (shrink)
