It has been argued by Hull and others that a remnant of essentialism impeded taxonomic progress until systematists abandoned attempting to define taxa on the basis of characters necessary and sufficient for group membership. The advent of cladistics suggests instead that it is an essentialistic view of characters, not of taxa, that should be abandoned, and that only a transformational view of characters allows evolutionary novelties to be identified, much less explained. Conventional Darwinian explanations are not tautologous but are difficult (...) to test and scarcely explain evolutionary novelties, probably because of their emphasis on genetic rather than epigenetic (developmental) processes.

All biologists use classifications to one degree or another, and those of us who work on classifications use the results of all other biologists to one degree or another, so you might reasonably expect that biologists in general would share some common conception of how classifications should be constructed and how they can be used. Certainly one might expect that all taxonomists, at least, would share such a perspective. But this is not the case; in fact, the theory of taxonomy (...) is at present a very controversial subject, with much of the controversy revolving around the question of how to go about constructing an ideal classification.Surprisingly, there is relatively little controversy about what properties an ideal classification would have. Admittedly, different terms are used to describe these properties, various workers arguing that classifications should be maximally stable, or maximally useful, or maximally informative, or maximally testable, or maximally refutable, or maximally predictive, and so on.

This article reports results from a program that produces high‐quality animation of facial expressions and head movements as automatically as possible in conjunction with meaning‐based speech synthesis, including spoken intonation. The goal of the research is as much to test and define our theories of the formal semantics for such gestures, as to produce convincing animation. Towards this end, we have produced a high‐level programming language for three‐dimensional (3‐D) animation of facial expressions. We have been concerned primarily with expressions conveying (...) information correlated with the intonation of the voice: This includes the differences of timing, pitch, and emphasis that are related to such semantic distinctions of discourse as “focus,”“topic,” and “comment,”“theme” and “rheme,” or “given” and “new” information. We are also interested in the relation of affect or emotion to facial expression. Until now, systems have not embodied such rule‐governed translation from spoken utterance meaning to facial expressions. Our system embodies rules that describe and coordinate these relations: intonation/information, intonation/affect, and facial expressions/affect. A meaning representation includes discourse information: What is contrastive/background information in the given context, and what is the “topic” or “theme” of the discourse? The system maps the meaning representation into how accents and their placement are chosen, how they are conveyed over facial expression, and how speech and facial expressions are coordinated. This determines a sequence of functional groups: lip shapes, conversational signals, punctuators, regulators, and manipulators. Our algorithms then impose synchrony, create coarticulation effects, and determine affectual signals, eye and head movements. The lowest level representation is the Facial Action Coding System (FACS), which makes the generation system portable to other facial models. (shrink)

This research explored the feasibility of using multidimensional scaling (MDS) analysis in novel combination with other techniques to study comprehension of epistemic adverbs expressing doubt and certainty (e.g., evidently, obviously, probably ) as they relate to health communication in clinical settings. In Study 1, Australian English speakers performed a dissimilarity-rating task with sentence pairs containing the target stimuli, presented as “doctors' opinions.” Ratings were analyzed using a combination of cultural consensus analysis (factor analysis across participants), weighted-data classical-MDS, and cluster analysis. (...) Analyses revealed strong within-community consistency for a 3-dimensional semantic space solution that took into account individual differences, strong statistical acceptability of the MDS results in terms of stress and explained variance, and semantic configurations that were interpretable in terms of linguistic analyses of the target adverbs. The results confirmed the feasibility of using MDS in this context. Study 2 replicated the results with Canadian English speakers on the same task. Semantic analyses and stress decomposition analysis were performed on the Australian and Canadian data sets, revealing similarities and differences between the two groups. Overall, the results support using MDS to study comprehension of words critical for health communication, including in future studies, for example, second language speaking patients and/or practitioners. More broadly, the results indicate that the techniques described should be promising for comprehension studies in many communicative domains, in both clinical settings and beyond, and including those targeting other aspects of language and focusing on comparisons across different speech communities.

Dr. Norman L. Geisler has been called the "father of evangelical Christian philosophy." He has written more than one hundred books and taught at universities and top seminaries for some fifty-six years. He was the first president of the Evangelical Philosophical Society and the founder and first president of the International Society of Christian Apologetics. He has spoken or debated in more than two dozen countries and held pastoral/pulpit ministries in four states. Many view him as a cross between (...) Thomas Aquinas and Billy Graham. No one has done more to communicate the modern challenges of the Faith to the "average" Christian, to the church, and to the academy. This volume offers creative and constructive essays from twenty-three contributors, all notable in their own right, who preserve and propagate Dr. Geisler's ideas and express appreciation for his influence. Those who know him best say he is "true, faithful, and blessed by God!" -- from book cover. (shrink)

When Did I Begin? investigates the theoretical, moral, and biological issues surrounding the debate over the beginning of human life. With the continuing controversy over the use of in vitro fertilization techniques and experimentation with human embryos, these issues have been forced into the arena of public debate. Following a detailed analysis of the history of the question, Reverend Ford argues that a human individual could not begin before definitive individuation occurs with the appearance of the primitive streak about two (...) weeks after fertilization. This, he argues, is when it becomes finally known whether one or more human individuals are to form from a single egg. Thus, he questions the idea that the fertilized egg itself could be regarded as the beginning of the development of the human individual. The author also differs sharply, however, from those who would delay the beginning of the human person until the brain is formed, or until birth or the onset of conscious states. (shrink)

Not all of the responses to fascism in the English speaking world were hostile. With the aim of providing a representative sample, Routledge here re-issues Norman Hillson’s _I Speak of Germany_. First published in 1937, this is an account of the author’s travels in Germany, and is largely sympathetic to the changes wrought by the regime. Like others adopting a similar position, the author believes that the terms of the Versailles treatment put Germany in an impossible position, and that (...) the Nazis had inspired a recovery. Racial politics, whilst not ignored, are not seen as being at the heart of the programme – ‘obsession of race purity maybe a little absurd and quite impractical of realization’. (shrink)

The rapidly increasing numbers of elderly people in our society have raised some important moral questions: How should we distribute social resources among different age groups? What does justice require from both the young and the old? In this book, Norman Daniels offers the first systematic philosophical discussion of these urgent questions, advocating what he calls a "lifespan" approach to the problem: Since, as they age, people pass through a variety of institutions, the challenge of caring for the elderly (...) becomes the prudent allocation of public resources among the various stages of people's lives. Using this philosophical approach, Daniels addresses specific public policy issues such as the allocation of medical funds, the adequacy of long-term care, current Medicare cost-containment measures, and the equitable distribution of income support over the lifespan and between generations.

The Metaphysics of Theism presents an explanation and evaluation of Aquinas's natural theology, the paradigm of which is the first book of the Summa contra gentiles. Natural theology provides the traditional and still central means of integrating philosophy with (some of) theology. What makes this enterprise natural theology is its forgoing of appeals to revelation as evidence for the truth of propositions. What makes it natural theology is its agenda to investigate, by means of analysis and argument, not only the (...) existence and nature of God but also the relation of everything else—especially human nature and behaviour—to God, considered as reality's first principle. Natural theology still offers the best route by which philosophers can, as philosophers, approach theological propositions. The one presented in this book undertakes to show that there must be a necessary being that constitutes the ultimate explanation of the universe. (shrink)

Film theorists talk enthusiastically these days in terms of semiotics, sutures, and systems of meaning. I think we can usefully frame these theories by some evidence as to how some actual readers make actual theories from an actual film. To that end, I would like to explore here what three people, Agnes, Norm, and Ted, said about The Story of O. It seems to me that if any film should demonstrate the fixity of semiotic and other codes, surely a pornographic (...) film should.You might call this essay, then, the story of this I storying three other I’s storying The Story of O.1 “Storying” is Audrey Grant’s verb, and by it she intends the representing of an event in your own mind and telling somebody about it.2In this essay, then, I propose to tell you how I represent in my mind how these three individuals represented in their minds The Story of O.Sometimes we felt or thought about the film more or less alike, and sometimes we squarely contradicted one another. I want to ask two questions of these responses. First, how can we relate their variety to the singleness of the film? Second, how can we relate their variety to the generality of any codes that govern the seeing of films? Norman N. Holland is Milbauer Eminent Scholar at the University of Florida.

The Metaphysics of Theism is the definitive study of the natural theology of Thomas Aquinas, the greatest of medieval philosophers, written by one of the world's most eminent scholars of medieval thought. Natural theology is the investigation by analysis and rational argument of fundamental questions about reality, considered in relation to God. Professor Kretzmann shows the continuing value of Aquinas's doctrines to the philosophical enterprise today; he argues that natural theology offers the only route by which philosophers can, as philosophers, (...) approach theological propositions, and that the one presented in this book is the best available natural theology.

This paper addresses three questions raised by recent literature on the concept of ‘autonomy’. (I) Should the value of autonomy more properly be seen as a moral constraint or as a goal of action? (2) Is autonomy either possible or desirable, given the ways in which human beings are located within a situation and a community? (3) If autonomy is a desirable goal, is it a universal value or merely one appropriate to modern liberal-democratic societies? Use is made of the (...) distinction between ‘weak’ and ‘strong’ versions of the concept of ‘autonomy’, which helps to provide an answer to the first question. It is also important, however, to recognise the continuity between the weak and strong versions, and this recognition helps to supply answers to the second and third questions. (shrink)

A powerful work of moral and political philosophy.The idea which I shall present here came to me more or less out of the blue. I was on a train some five years ago, on my way to spend a day at Headingley and I was reading a book about the death camp at Sobibor... The particular, not very appropriate, conjunction involved for me in this train journey... had the effect of fixing my thoughts on one of the more dreadful features (...) of human coexistence, when in the shape of a simple five-word phrase the idea occurred to me. In The Contract of Mutual Indifference, Norman Geras discusses a central aspect of the experience of the Holocaust with a view to exploring its most important contemporary implications. In a bold and powerful synthesis of memorial, literary record, historical reflection and political theory, he focuses on the figure of the bystander -- the bystander to the destruction of the Jews of Europe and the bystander to more recent atrocities -- to consider the moral consequences of looking on without active response at persecution and great suffering. Geras argues that the tragedy of European Jewry, so widely pondered by historians, social scientists, psychologists, theologians and others, has not yet found its proper reflection within political philosophy. Attempting to fill the gap, he adapts an old idea from within that tradition of enquiry, the idea of the social contract, to the task of thinking about the triangular relation between perpetrators, victims and bystanders, and draws a somber conclusion from it. Geras goes on to ask how far this conclusion may be offset by the hypothesis of a universal duty to bring aid. The Contract of Mutual Indifference is an original and challenging work, aimed at the complacent abstraction of much contemporary theory. It is supplemented by three shorter essays on the implications of the Jewish catastrophe for conceptions of human nature and progress and for certain types of Marxist explanation. (shrink)

In lieu of an abstract, here is a brief excerpt of the content:Journal of the History of Ideas 63.3 (2002) 501-519 [Access article in PDF] Nietzsche and Early Romanticism Judith Norman Nietzsche was in many ways a quintessentially romantic figure, a lonely genius with a tragic love-life, wandering endlessly (through Italy, no less) before going dramatically mad, taken by his gods into the protection of madness (to quote Heidegger's epithet on Hölderlin, one of Nietzsche's childhood favorites). 1 But this (...) is to be a romantic in an uncapitalized manner, and has nothing to do with the literary movement of Romanticism, a movement from which, as is well-known, Nietzsche distanced himself loudly and vigorously. Nietzsche famously follows Goethe in his verdict that Romanticism is a form of sickness and classicism a form of strength, and commentators, for the most part, have accepted this self-description. 2 That is, they do not blithely identify Nietzsche with that nineteenth-century artistic movement, whose proponents include Victor Hugo, Eugene Delacroix, and Richard Wagner. 3But Romanticism is a plural phenomenon. When Goethe made his famously dismissive remark, he was clearly not talking about Hugo and Wagner; he meant Romanticism in an earlier incarnation. Commentators have been less reticent about finding all sorts of affinities between Nietzsche and some of these earlier movements. In particular Nietzsche is frequently and positively compared to Jena Romanticism (also known as early Romanticism), a movement whose principal figures included August and Friedrich Schlegel, Novalis, Tieck, Schleiermacher, and Schelling, and the writings they published in the 1790s, principally in the journal, Athenaeum. It is this romantic movement that will be the focus of my paper. Jena romantics, while Grecophile, had nothing to do with Rousseauean primitivism (they were well aware that their image of the [End Page 501] Greeks reflected contemporary fantasies more than historical reality), they had no cult of the genius, and they did not valorize emotion above reason. 4 What was central to their movement was profound skepticism about the viability of traditional attitudes towards truth, an intellectually rigorous theory of art that gave particular weight to playfulness, fragmented writing, the notion of literary irony, a sense that the philosopher ought to be or become more of an artist (though not a genius)—and, correlatively, that philosophy is or ought to become more artistic. All of which sounds decidedly Nietzschean. Romanticizing Nietzsche While Nietzsche himself never makes the connection, he never explicitly distances himself from the authors of Jena romanticism in the way he does from later romantic figures. 5 Indeed, he barely mentions the Jena romantics by name and probably never read Friedrich Schlegel, the figure most closely associated with this romantic movement. 6 As such, there is certainly space for commentators to argue for a close if tacit intellectual connection between Nietzsche and Jena romanticism; indeed, one commentator speaks of a fundamental affinity, 7 another calls Nietzsche the last romanticist, and yet another claims that "[Nietzsche's] story makes sense only when read in the larger context of his Romantic predecessors' history." 8It is undeniable that Nietzsche came out of a philological tradition inaugurated by the Schlegels (and developed by Schelling) which juxtaposed the Dionysian and the Apollinian in Greek tragedy. According to Lacoue-Labarthe, "an entire tradition of academic philosophy (which, on his own initiative, Nietzsche had joined) revolved around precisely this opposition." 9 At least in [End Page 502] his earlier works Nietzsche's view of the Greeks was influenced by (if not predicated on) the scholarly research and interpretative theories of figures associated with Jena romanticism. How profound and enduring this influence might have been is an interesting question, but not one I will explore at present. I will not discuss the influence of the Jena romantics in their scholarly capacity as classical philologists, but rather focus on any impact they may have had as philosophically minded literary critics during the 1790s. Similarly, I will not look at The Birth of Tragedy but rather focus on claims made concerning the romantic tendencies of Nietzsche's later work. A body of scholarship has been building which claims that the critical theories of Jena... (shrink)

The definitive study of the natural theology of Thomas Aquinas, the greatest medieval philosopher, written by one of the world's most eminent scholars of medieval thought.

In lieu of an abstract, here is a brief excerpt of the content:Objective Reality of Ideas in Descartes, Caterus, and Su irez NORMAN j. WELLS IT HAS LONG BEEN ACKNOWLEDGEDthat Francisco Sufirez's distinction between a formal and an objective concept exercised some influence upon Descartes's teaching on 'idea'.' It would appear, however, that not enough attention has been given to that distinction of Sufirez (and especially to another to be mentioned shordy) to aid in dispelling what I take to (...) be a widespread confusion and misunderstanding with regard to 'idea' in Descartes, especially with respect to 'idea' taken 'objectively'. Much, if not all, of the confusion in question has to do with Descartes's admittedly equivocal use of the term 'idea'. For he had allowed that 'idea' could be taken 'materially' (materialiter), on the one hand, for the knowing activity of the intellect. On the other hand, it could be taken 'objectively' (objective) for the thing (res) represented by that knowing activity.' At this point, the contemporary reader can only be brought up short, See E.

It is clear that two realities are to be causally accounted for. The [33] 34 JOURNAL OF THE HISTORY OF PHILOSOPHY 28"1 JANUARY 1990 conditioned as we are by an appreciation of 'objectivity' altogether extramental! It makes for a considerable wrench of perspective to do justice to Descartes's acknowledged doctrine of intramental objectivity and an intramental 'thing represented' (resrepraesentata). 'Idea', then, in traditional Cartesian fashion, designates the act of representing as well as the 'thing represented '. S Yet, for all this, and despite repeated expressions of the same doctrine, there is a persistent tendency in the history of Cartesianism and its scholarship to interpret 'idea' taken 'objectively' as in some way representative. Contrary to what I take to be Descartes's constant position, such a rendering unwittingly transfers that function which is proper to the cognitive activity, mind is the efficient cause of its cognitive activity. With respect to ideas taken 'objectively', such as the ideas of God and the triangle on the levels of metaphysical and mathematical intelligibility, an efficient cause, extrinsic to the mind, is certainly at issue. For here we are in the presence of what is independent of the mind, however intramental it may be. On the triangle, see Medit. 5; 7: 64. ]4s7 : "...est tamen profecto determinata quaedam ejus natura, sire essentia, sive forma, immutabUis et aeterna, quae a me non efficta est, nec a mente mea dependet."

There is a hoary tradition in moral philosophy that assumes we cannot determine which moral theory is acceptable or correct unless we have available a correct theory of human nature, or, in its more modern form, of the person. With such a theory of the person, however, we could at least narrow down the choice among competing ethical theories. A more recent tradition, at least in one of its standard interpretations, agrees it would be necessary to have a correct theory (...) of the person before we could determine an acceptable moral theory, but it denies there is a determinate nature of the person to be captured in such a theory. The plasticity of the person, according to this strand of Marxist theory, rules out the possibility of there being universal moral theory at all. In this paper, I would like to explore a view that treads an intermediate path. It agrees with the Marxist denial that there is a determinate nature of the person, a deep fact of the matter, that can be abstracted from the social matrix and made the subject of a theory of the person. And, it agrees with both traditions that moral theory depends on and embodies a theory of the person. But, by making the problem of arriving at an acceptable view of the person itself something that depends on overall theoretical considerations, including moral ones, the intermediary, view may be able to avoid the type of moral relativism associated with the Marxist view.

Some people will confront Alzheimer's with a measure of resignation, a determination to struggle against the progressive debilitation and to extract whatever comforts and benefits they can from their remaining existence. They are entitled to pursue that resolute path. For other people, like myself, protracted maintenance during progressive cognitive dysfunction and helplessness is an intolerably degrading prospect. The critical question for those of us seeking to avoid protracted dementia is how best to accomplish that objective.One strategy is to engineer one's (...) own death while still mentally competent to do so (even in the stage of mild dementia). If I were to use a preemptive strategy in the face of a dementia diagnosis, I would probably choose to stop eating and drinking, a process known as voluntarily stopping eating and drinking. An alternative tactic for avoiding prolonged dementia would be to allow oneself to decline into moderate dementia—thus losing capacity to perform self‐deliverance or even to make serious medical decisions—but before getting to that point to provide advance instructions rejecting prospective life‐sustaining medical interventions. These advance instructions would authorize palliative but not curative measures. My current personal instructions define the point of intolerable cognitive decline triggering medical nonintervention as “mental deterioration to a point when I can no longer read and understand written material such as a newspaper or financial records such as a checkbook.” These instructions dictate allowing my demise at a point of moderate dementia when I may not be perceptibly suffering, when I may still be getting some rudimentary satisfaction from my debilitated life, and when I no longer recall the preoccupation with personally intolerable indignity that motivated my instructions. Can I expect that my advance instructions will be implemented in those circumstances? Is it lawful, and is it moral for a surrogate decision‐maker and associated caregivers to allow an uncomprehending, ostensibly content but demented individual to die? My analysis herein contends that it is not only lawful and moral but also legally required to implement clear, considered advance instructions even at a stage of moderate dementia. (shrink)

Most economists are committed to some version of egoism. After distinguishing among the various sorts of egoistic claims, l cite the empirical literature against psychological egoism and show that attempts to account for this data make these economists' previous empirical claims tautological. Moreover, the assumption of egoism has undesirable consequences, especially for students; if people believe that others behave egoistically, they are more likely to behave egoistically themselves. As an alternative to egoism I recommend the commitment model of Robert Frank. (...) The equivalent of egoism at the organizational level is that business firms seek (should seek) to maximize profits. I present arguments to show that a conscious attempt by managers to maximize profits is likely to fail. A committed altruism is more likely to raise profits. I suggest that a firm should take as its primary purpose providing meaningful work for employees. (shrink)
