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.

Conspicuous consumption associated with status reinforcement behavior can be explained in terms of costly signaling, or strategic handicap theory, first articulated by Zahavi and later formalized by Grafen. A theory is introduced which suggests that the evolutionary raison d’être of status reinforcement behavior lies not only in its effects on lifetime reproductive success, but in its positive effects on the probability of survival through infrequent, unpredictable demographic bottlenecks. Under some circumstances, such “wasteful” displays may take the form of displays of (...) altruistic behavior and generosity on the part of high status individuals, in that is signals the ability to bear the short-term costs of being generous or “cooperative,” while at the same time reinforcing the long-term benefits of higher status.

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.

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 identification of a set of mutually exclusive and exhaustive propositions concerning the states of quantum systems is a corner stone of the information-theoretic foundations of quantum statistics; but the set which is conventionally adopted is in fact incomplete, and is customarily deduced from numerous misconceptions of basic quantum mechanical principles. This paper exposes and corrects these common misstatements. It then identifies a new set of quantum state propositions which is truly exhaustive and mutually exclusive, and which is compatible with (...) the foundations of quantum theory. (shrink)

In a seminal 1977 article, Rumelhart argued that perception required the simultaneous use of multiple sources of information, allowing perceivers to optimally interpret sensory information at many levels of representation in real time as information arrives. Building on Rumelhart's arguments, we present the Interactive Activation hypothesis—the idea that the mechanism used in perception and comprehension to achieve these feats exploits an interactive activation process implemented through the bidirectional propagation of activation among simple processing units. We then examine the interactive activation (...) model of letter and word perception and the TRACE model of speech perception, as early attempts to explore this hypothesis, and review the experimental evidence relevant to their assumptions and predictions. We consider how well these models address the computational challenge posed by the problem of perception, and we consider how consistent they are with evidence from behavioral experiments. We examine empirical and theoretical controversies surrounding the idea of interactive processing, including a controversy that swirls around the relationship between interactive computation and optimal Bayesian inference. Some of the implementation details of early versions of interactive activation models caused deviation from optimality and from aspects of human performance data. More recent versions of these models, however, overcome these deficiencies. Among these is a model called the multinomial interactive activation model, which explicitly links interactive activation and Bayesian computations. We also review evidence from neurophysiological and neuroimaging studies supporting the view that interactive processing is a characteristic of the perceptual processing machinery in the brain. In sum, we argue that a computational analysis, as well as behavioral and neuroscience evidence, all support the Interactive Activation hypothesis. The evidence suggests that contemporary versions of models based on the idea of interactive activation continue to provide a basis for efforts to achieve a fuller understanding of the process of perception.

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)

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)

In lieu of an abstract, here is a brief excerpt of the content:LettersJames L. Walsh, Moira M. McQueen, Kevin O'Rourke, and Jean deBloisEarly Delivery of the Anencephalic InfantMadam:In the March 1994 issue of the Kennedy Institute of Ethics Journal, Kevin O'Rourke and Jean deBlois have replied to an article of ours (KIEJ, December 1993) on the early induction of the anencephalic fetus. They agree with our conclusion that such early delivery may be morally acceptable, but argue that our justification is (...) flawed. Exchanges on the subject probably could continue ad nauseam; here we simply state some of the elements of their article that leave us perplexed.1. The phrase "prolonging the life of" (p. 49) has one meaning in the case of artificial life supports, which may be unwarranted interventions, but it has a different meaning when it refers to not interfering with a person's enjoyment of necessary natural means of preserving his or her life. Inducing labor prior to viability, which denies the natural means of life support without a possible substitute, has more in common with smothering a dying patient than the nonemployment of or withdrawing of artificial means of life support. To refer to the death of the fetus here as an effect is rather like saying that I suffocated you and the effect of the suffocation is your death. This is quite different from induction after viability where the induction can have different effects.2. If the authors were correct that "the prohibition on inducing delivery before viability is predicated upon the assumption that the fetus in utero is a human being with the potential for further development" (p. 49) and the anencephalic has none, why is there need to employ the principle of double effect? They say that there is no moral obligation to prolong the life of the anencephalic fetus. Just as there is no need for the principle in cases of withdrawing unwarranted artificial life support, so there would be no need for it here. Because the authors seem to perceive a complete disjunction between direct and indirect killing (allowing to die being in the category of indirect killing), it seems that they are unable to let their argument rest here, but have to justify the death that occurs.3. The example concerning smothering and the nonemployment of aggressive interventions (p. 49) explains well the difference between killing and allowing to die. But allowing to die is not indirectly killing since it occurs as a result of the disease and not from the causality of the agent.4. How can we cause something and not intend it? There are instances in which we simply "permit" evil events, but where we are not the cause. For example, evil events may be attributable to the bad will of others. Legislators make just laws knowing that some people of bad will will break them for their own advantage. Here the legislators really do permit evil. Neither are we the cause of death when we allow a person to die by not imposing unwarranted means of life support; we permit his or her death. But can we so readily designate by "permit" [End Page 184] what we knowingly choose to bring about? O'Rourke and deBlois use interchangeably "indirectly intended" and "unintended" for what is caused by our actions; "indirectly intended" is a better designation than "unintended." The whole package, including all foreseen effects, is intended. Evil "happening" (p. 51) as a result of an action that I place can refer either to evil as caused by my action or to evil as arising from a cause apart from my action. Only in this latter sense do I permit evil and not intend it, either directly or indirectly.5. The fourth condition of the principle of double effect is given as follows: "There must be a proportionately grave reason for placing the act. The greater the evil, the more cogent the reason must be for performing the act" (p. 50). How the authors can abstract from balancing goods and evils here is beyond us.6. We cannot follow the authors' use of the term "morally good" with respect to the induced delivery (p. 50). The problem is concerned with the morally right... (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.

Hirsch’s revision results from his attempt to think through the difficult question that underlies the whole essay: How does the movement of time and circumstance affect the stability of meaning? The first part of his answer is that the relation between original meaning and subsequent understanding or applications of that meaning is analogous to the relation between a concept and its extension. For example, if he reads Shakespeare’s sonnet 55 and applies it to his beloved, and one of us reads (...) it and applies it to his beloved, “that does not make the meaning of the sonnet different for us, assuming that we both understand that the text’s meaning is not limited to any particular exemplification but rather embraces many, many exemplifications” . That is, the sonnet has a status analogous to that of the concept “bicycle,” and the two applications have a status analogous to that of a three-speed and a ten-speed bicycle. Whereas Hirsch formerly considered such exemplifications part of a text’s significance, he now considers them part of its meaning. This revision indicates that for Hirsch meaning is not the product of a consciousness producing an intrinsic genre but of a consciousness communicating something broader and more general than an intrinsic genre—an intention-concept that can have numerous extensions or exemplifications, including many that the originating consciousness could not have anticipated. Formerly, Hirsch used intrinsic genre to describe that sense of the whole which governed the horizon of developing meaning and which, when the work was completed—when all the blanks were filled in—gave the work its specific determinate meaning. That is, determinacy of meaning was in large part a function of narrowing the class of implications; when the work was completed, the class of implications was restricted to those synonymous with expressed meaning. In short, in the old theory, meaning-intention is a “narrow,” not a broad “concept.” James L. Battersby, professor of English at Ohio State University, is the author of Rational Praise and Natural Lamentation: Johnson, Lycidas, and Principles of Criticism and Elder Olson: An Annotated Bibliography. He is currently at work on a study of the relationship between “thought” and structure in various genres. James Phelan is associate professor English at Ohio State University and the author of Worlds from Words: A Theory of language in Fiction. His work in progress concerns character and narrative progression. (shrink)

In lieu of an abstract, here is a brief excerpt of the content:Buddhist-Christian Studies 22.1 (2002) 251-254 [Access article in PDF] James Fredericks Interview The 2002 winner of the Frederick J.Streng Book Award is James Fredericks, professor ofTheological Studies at Loyola Marymount University in Los Angeles, California. Professor Fredericks received the award for his book, Faith Among Faiths: Christian Theology and the Non-Christian Religions, published by Paulist Press (New York) in 2001. Buddhist-Christian Studies asked James about his (...) writing of the volume.Buddhist-Christian Studies: Why did you write Faith Among Faiths?James Fredericks: I wanted to help Christians think about the problems that the "pluralist" view of religious diversity poses for inter-religious dialogue.How does the book do that?By making a sustained criticism of the claim that religions are differing interpretations of the same transcendent "Reality." This notion is a problem for a religion of revelation, like Christianity, but also for a religion like Buddhism that has a sophisticated critique of metaphysics. Pluralist thinkers impose a meta-religious grand narrative on all the religions and demand that the religions conform to this grand narrative in the name of "tolerance."This kind of thinking has roots in the European Enlightenment and has affinities with some strands of Hindu thought, especially the "neo-Hindu" thinkers. I do not think that this approach fosters dialogue in depth. If Buddhism and Christianity are varying interpretations of the same ultimate "Reality," then what does Buddhism have to teach Christians that is of genuine theological importance? The obvious differences that distinguish Buddhism from Christianity are of little theological interest to Christians because they are of no soteriological consequence. The pluralist approach is a dead end for dialogue.And the way forward?What I call "comparative theology." I think of this as an alternative to what Christians call the "theology of religions."What's the difference?Theologies of religion interpret the meaning of other religious traditions from within the perspective of Christian tradition. Karl Rahner's theology of the anonymous Christian and Karl Barth's rejection of all religions as "unbelief" are both examples of a theology of religion. John Hick's pluralist model of religions is also a kind of theology of religions. This entire project has reached an impasse within Christianity. As an alternative, I propose that Christians recognize that Buddhism and Christianity [End Page 251] are linked by some significant similarities and distinguished from each other by significant differences.How does that break the impasse?Christians have something of genuine value to learn by entering humbly into dialogue with Buddhists. By taking differences seriously, dialogue becomes a way for Christians to do their own theology collaboratively with Buddhists. In the medieval period, Christians did theology in dialogue with Aristotle and Plato. Today, I want Christians to do theology in dialogue with Nagarjuna and Dogen. Therefore doing theology comparatively is to step beyond the notion of a theology of religions. Comparative theology does not begin with the assumption that Buddhism is a relatively obscured form of the same truth Christians affirm (Rahner) or that Buddhism and Christianity are relatively equal expressions of a truth that transcends them both (Hick). The purpose of dialogue is not to show how we are all really trying to say the same thing. ForChristians, at least, dialogue with Buddhists is a genuinely demanding way of doing theology.Any other reasons for the book?Yes. To promote friendships among Buddhists and Christians. These "inter-religious friendships" are a good way for Christians to practice their faith. My own friendships with Buddhists, both here in the USA and in Asia, are central to my spirituality and my work as a theologian. In a sense, I have never been in dialogue with "Buddhism." All my dialogues have been with actual Buddhists, with all their personal strengths and weaknesses, successes and failures. I am happy to say that, over the years, I have had some skillful teachers who have taught me not only the Dharma, but also taught me new ways to think about Christianity.Was it a difficult book to write?My book was written after years of dialogue with Buddhists and much research and...

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)

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.

I show that Frege's statement (In the Epilogue to his Grundgesetze der Arithmetic v. II) of a way to avoid Russell's paradox is defective, in that he presents two different methods as if they were one. One of these "ways out" is notably more plausible than the other, and is almost surely what Frege really intended. The well-known arguments of Lesniewski, Geach, and Quine that Frege's revision of his system is inadequate to avoid paradox are not affected by the ambiguity (...) of Frede's statement. But a rectnt argument by Linsky and Schumm (Analysis 82 (1971-72), 5-7), intended as a very simple derivation of a contradiction within Frege's revised system, is valid only for the less plausible of the two versions of Frege's way out, and thus is not an effective attack on the revision that Frege intended to make.

If the ordinary quantal Liouville equation ℒρ= $\dot \rho $ is generalized by discarding the customary stricture that ℒ be of the standard Hamiltonian commutator form, the new quantum dynamics that emerges has sufficient theoretical fertility to permit description even of a thermodynamically irreversible process in an isolated system, i.e., a motion ρ(t) in which entropy increases but energy is conserved. For a two-level quantum system, the complete family of time-independent linear superoperators ℒ that generate such motions is derived; and (...) a physically interesting example is presented in detail.
