To students and practitioners of anamorphic art, the name of Jean-François Niceron is more than preeminent; it has become iconic. La Perspective Curieuse was first published in 1638. An augmented version was then translated into Latin by Mersenne in 1646. A newly amended and augmented version was retranslated into French by Roberval in 1652. This book is an English translation of the 1652 text, with reference to the 1638 and 1646 versions. Considering the continued high reputation of the book, the (...) mathematics have been checked for correctness and consistency, and the authors have provided a full commentary, pointing out the most difficult turns of the 17th-century French, the respective contributions of Niceron, Mersenne and Roberval, and explaining Niceron's greatest insights and weaknesses.

After his father passed away, James Nolan's mother gave him a box of materials that his dad had kept private. To Nolan's complete surprise, the contents revealed the role his grandfather had played as a doctor in the Manhattan Project. Dr. Nolan, it turned out, had been a significant figure. A talented radiologist, he cared for the scientists on the Project, helped organize the safety and evacuation plans for the Trinity Test at Alamogordo, escorted the "Little Boy" bomb from (...) Los Alamos to Japan, and was one of the first Americans to enter the irradiated ruins of Hiroshima and Nagasaki. The documents set Nolan on a hunt for more information about his grandfather and more generally about the conflicted role that medical personnel played in the early years of atomic testing. The result is a compelling history of the dawn of the atomic age as seen through the eyes of men and women torn between their duty and desire to win the war and their oath to protect life. Nolan follows his grandfather and medical colleagues as they seek to maximize safety while serving leaders determined to minimize delays, and as they consider the ethics of ending the deadliest of all wars with the most lethal of all weapons. The result, Nolan shows, was a very human pattern of caution, co-optation, and complicity. A vital and vivid account of a largely unknown chapter in atomic history, Delivering Little Boy is also a profound meditation on the professional and moral dilemmas that ordinary people face in extraordinary times.

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.

Humanitarian health care practitioners working outside familiar settings, and without familiar supports, encounter ethical challenges both familiar and distinct. The ethical guidance they rely upon ought to reflect this. Using data from empirical studies, we explore the strengths and weaknesses of two ethical models that could serve as resources for understanding ethical challenges in humanitarian health care: clinical ethics and public health ethics. The qualitative interviews demonstrate the degree to which traditional teaching and values of clinical health ethics seem insufficient (...) for addressing all the realities of health care practice during humanitarian missions. They equally suggest that greater good orientations of public health ethics can thwart the best intentions of health care professionals wanting to attend to the interests of individual patients. Even though neither is complete on its own for helping guide health professionals on field missions, taken together these models have much to offer. At the same time, the narratives of the humanitarian health care workers illustrate how some of the crucial differences between public health ethics and clinical ethics generate tensions in humanitarian health practice. We offer an analysis of some of the complexities this creates for humanitarian health care ethics, and consider ways of adjudicating between the two models. (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.

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.

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...

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.

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.

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)

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 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)

This paper explores the place of evil in Plato’s thought through the lens of the Philebus. I show that the concept of evil in this dialogue is in broad agreement with the classic Christian position which accents metaphysically its privative and derivative character and morally its rebellious and self-oriented character. The entryway into the issue is 29d9–e1, where a “power of dissolution” is proposed in addition and opposition to the power of generation and mixture, and then quickly rejected. Such a (...) power would be both metaphysically and ethically subversive, or in short, evil. Plato appears to suppress the possibility of evil, but in fact, he relocates the power of dissolution within the unlimited genos in order to show its necessary subordination to and dependence on the limiting and causal principles within generated beings. Evil, on a metaphysical level, is subject to good. On an ethical level, however, the possibility of subversion remains and is exemplified in the dialogue in the radical hedonism of Philebus. After showing how hedonism manifests the power of dissolution in human life, I conclude by remarking the ultimate practical proof towards which this dialogue, and others, points in defense of its claims.

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.

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)

A combination of emerging life support technologies and entrenched organ donation practices are complicating the physician's task of determining death. On the one hand, technologies that support or replace ventilation and circulation may render the diagnosis of death ambiguous. On the other, transplantation of vital organs requires timely and accurate declaration of death of the donor to keep the organs as healthy as possible. These two factors have led to disagreements among physicians and scholars on the precise moment of death. (...) In this article, I suggest that the debate about exactly when a person dies can benefit from distinguishing the strict biological concept of death from the medical standards for determining human death, and I show how an appreciation of the difference between the permanent and irreversible cessation of circulation is helpful in understanding the reasons for the two approaches to determining when death should be declared.

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)
