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)

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.

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)

I consider the role of cognitive modeling in cognitive science. Modeling, and the computers that enable it, are central to the field, but the role of modeling is often misunderstood. Models are not intended to capture fully the processes they attempt to elucidate. Rather, they are explorations of ideas about the nature of cognitive processes. In these explorations, simplification is essential—through simplification, the implications of the central ideas become more transparent. This is not to say that simplification has no downsides; (...) it does, and these are discussed. I then consider several contemporary frameworks for cognitive modeling, stressing the idea that each framework is useful in its own particular ways. Increases in computer power (by a factor of about 4 million) since 1958 have enabled new modeling paradigms to emerge, but these also depend on new ways of thinking. Will new paradigms emerge again with the next 1,000‐fold increase? (shrink)

'The interpretours of Plato,' wrote Sir Thomas Elyot in The Governour, 'do think that the wonderful and incomprehensible order of the celestial bodies, I mean sterres and planettes, and their motions harmonicall, gave to them that intensifly and by the deepe serche of raison beholde their coursis, in the sondrye diversities of number and tyme, a forme of imitation of a semblable motion, which they called daunsigne or sltation.' The image of the planets and stars engaged in an ordered and (...) measured dance is an ancient one. Plato articulated it in a passage in the Timaeus, where he likened the apparent motions of the planets and stars to 'choreiai'. Through the centuries the analogy has challenged Plator's interpreters to define and elaborate the image. Miller has examined a range of poetic and philosophical texts influenced by Plato cosmology, and has discovered frequent comparisons of the cosmic order to 'daunsigne.' He suggests that the vision of the cosmic dance did not develop at random in Western intellectual history but originated in a specific philosophical context and passed through stages of evolution that reflect Gnostic, Christian, Stoic, and Neoplatonic responses to Plato. He argues that the historical variations of the image were often closely related to adaption or criticisms of Plato's theories of visual perception and intellectual vision. The dance, in conjunction with images such as the Great chain of Being and the Lyre of the Heavens, became the dominant image of a peculiarly Late Antique world-view which Miller has called the 'poetic universe'; a world where metaphors, metonymies, and personifications could exist in fact as well as in word. The result of Miller's analysis is vast in scope. The nine chapters of the book each present a thesis on a particular author, but all function together like links in a chain. Miller has been described as 'an historian of visions'; the book has been likened to Auerbach's Mimesis. It is a remarkable contribution to an understanding of the complex interaction of ideas and images in time. (shrink)

This paper contends that, even though Husserl demonstrated that consciousness intends objects in the world rather than mental representations, he ultimately failed to provide a convincing account of how the ego constitutes itself and other egos. By reconfiguring consciousness as an operation rather than as a container, Husserl opened consciousness to the world and thereby overcame previous solipsistic frameworks. But despite his attention to the “things themselves,” his fidelity to another maxim—that all sense-bestowing activity be traced back to the operations (...) of the ego—prohibited him from fulfilling his goal of describing otherness accurately. This paper examines the tension between Husserl’s desire to describe phenomena and his mandate to constitute phenomena, to show that both cannot be accomplished simultaneously. If phenomenology is to come to terms with the challenge of otherness and describe self and other adequately, the demand that self and other be constituted within the ego must be relinquished.

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.

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 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)

Metaethical expressivism is typically characterised as the view that normative statements express desire-like attitudes instead of beliefs. However, in this paper I argue that expressivists should claim that normative statements express beliefs in normative propositions, and not merely in some deflationary sense but in a theoretically robust sense explicated by a theory of propositional attitudes. I first argue that this can be achieved by combining an interpretationist understanding of belief with a nonfactualist view of normative belief content. This results in (...) a view I call ‘interpretative expressivism’. I then argue that traditional arguments employed by expressivists that normative statements express noncognitive attitudes can just as well support the claim that normative statements express nonfactual or nonrepresentational beliefs. Finally, I argue that this view has a number of advantages to versions of expressivism that deny that normative statements express non-deflationary normative beliefs. (shrink)

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)

Notwithstanding these wise pronouncements, my project here is to characterize the biological phenomenon of death of the higher animal species, such as vertebrates. My claim is that the formulation of “whole- brain death ” provides the most congruent map for our correct understanding of the concept of death. This essay builds upon the foundation my colleagues and I have laid since 1981 to characterize the concept of death and refine when this event occurs. Although our society's well-accepted program of multiple (...) organ procurement for transplantation requires the organ donor first to be dead, the concept of brain death is not merely a social contrivance to permit us to obtain the benefits of organ procurement. Rather, the concept of whole- brain death stands independently as the most accurate biological representation of the demise of the human organism. (shrink)

The word buddhi is an important term of Indian philosophical discourse, but some aspects of its use have caused confusion and continue to occasion difficulties. This paper undertakes a survey of the usage of the word buddhi in general Sanskrit literature from its earliest late Vedic occurrences up to the middle of the first millennium CE. Signifying fundamentally “awareness,” the word “buddhi” is shown to refer often to a being’s persisting capacity or faculty of awareness and also, often, to the (...) content of a being’s awareness. There are also instances where it is hard to determine which of these two kinds of reference are intended in our written sources, and there are other instances where both senses seem present simultaneously. Various examples attest to the use of the word to refer to an affective and volitional capacity in a being—and to affective and volitional content—as well as to a cognitive faculty and cognitive content. One feature that occurs frequently in the word’s use is that this faculty and, or, its content, regularly describe alterations of a subject’s knowledge of the surrounding situation, the transformation of surrounding complexity or multiplicity into a simpler and more manageable mental construct—an understanding, an interpretation, a decision, a plan, etc. As the word buddhi is related to the primary Sanskrit word-family used to describe the concrete experience of awakening—moving from no awareness to clear awareness—it is not surprising that its more abstract usage would often incorporate a similar dynamic, a transition from less clear to more clear knowledge, a rendering of early knowledge to better and more useful knowledge, in short, a faculty of “intellect” that produces refined decisions, resolutions, and determinations. It is suggested that this element of its semantic profile contributed to the word’s eventually becoming the preferred word for the most important of the mental functions of beings in one of the most widespread philosophical psychologies of ancient India, that which ultimately became formally enshrined in the philosophical system “Sāṃkhya.”.

Patrick Olivelle’s two volumes presenting first the four oldest dharmasūtras, in updated and refurbished editions and new translations, and next his critical edition and translation of the Mānavadharmaśāstra are both meticulous works of fundamental scholarship that will stand as the normative forms of these five texts for decades to come. Olivelle’s contributions as an editor in each volume are very different, and these contributions are examined and discussed in some detail, particularly in the case of the critical edition of the (...) Manu, which presents a number of important issues of lower and higher textual criticism. In the case of the sūtra volume, the discussion turns to a general comparison of Olivelle’s translations of the sūtras to Bühler’s and then to a closer examination of Olivelle’s translational policies for the word dharma and two words in particular used by the sūtras to describe the good of doing dharma, kṣema and niḥśreyasa. In the discussion of the edition of Manu, particular attention is given to his assembly, analysis, and presentation of the fifty-three witnesses used for the new edition of the Manu. Following that, there is a discussion of the nature of the tradition that gave rise to the text and used it, a discussion that calls into question some of Olivelle’s basic conclusions about the formation and development of the text of the Manu śāstra.

“Whether Heidegger is labeled an existential atheist, a “pagan,” or whether his philosophy is used as a basis for contemporary theology, he is inalterably involved in the question of god. Such labels arise from a natural tendency to study Heidegger’s work individually rather than to see them as a developing whole, a “way” or “path,” as he himself calls it, on which there are obstacles, turns and a turning back. Dr. Perotti documents pertinent references to god and the divine throughout (...) the major works of Martin Heidegger, and collects and interprets those references into an evolving whole. Heidegger’s various views on the divine are seen as consistent and supportive of one another. Heidegger on the Divine shows that Heidegger’s “way” on the question of the divine is a significant and timely statement in its own right and is a particularly relevant critique of both theology and atheism”- Publisher.

The lesson is familiar. Kripke’s arguments in favor of a posteriori necessary truths annul the idea that conceivability is a guide to metaphysical possibility because determining that which is a priori is a separate issue from determining that which is necessary. Modal rationalists do not completely agree with this conclusion. Following recent work on two-dimensional semantics, David Chalmers suggests that two distinct semantic values can be assigned to a statement, depending on whether we consider possible worlds as counterfactual or counteractual. (...) The idea is that counterfactual possibilities yield familiar Kripkean intuitions, but that counteractuals fulfill the desired link between a priori conceivability and metaphysical possibility. In this paper, I discuss a problem for modalrationalism that arises through the use of material conditionals, or conditionals in the indicative mood. I then turn to Chalmers’ response, and suggest reasons why it is inadequate. I turn to another response from Chalmers, and suggest that, whilst it solves the fi rst issue, it is incapable of grounding modal rationalism. In conclusion I will suggest a way in which a tempered version of modal rationalism can be salvaged. (shrink)
