We examine the problem of generating definite noun phrases that are appropriate referring expressions; that is, noun phrases that (a) successfully identify the intended referent to the hearer whilst (b) not conveying to him or her any false conversational implicatures (Grice, 1975). We review several possible computational interpretations of the conversational implicature maxims, with different computational costs, and argue that the simplest may be the best, because it seems to be closest to what human speakers do. We describe our recommended (...) algorithm in detail, along with a specification of the resources a host system must provide in order to make use of the algorithm, and an implementation used in the natural language generation component of the IDAS system.

The emergence of controlled, Maastricht Category III, non-heart-beating organ donation programs has the potential to greatly increase the supply of donor solid organs by increasing the number of potential donors. Category III donation involves unconscious and dying intensive care patients whose organs become available for transplant after life-sustaining treatments are withdrawn, usually on grounds of futility. The shortfall in organs from heart-beating organ donation following brain death has prompted a surge of interest in NHBD. In a recent editorial, the British (...) Medical Journal described NHBD as representing “a challenge which the medical profession has to take up.”. (shrink)

Quine argued that any context allowing substitution of logical equivalents and coextensive terms is truth functional. We argue that Quine's proof for this claim is flawed.

Consequentialism is the family of theories that holds that acts are morally right, wrong, or indifferent in virtue of their consequences. Less formally and more intuitively, right acts are those that produce good consequences. A consequentialist theory includes at least the following three elements: an account of the properties or states in virtue of which consequences make actions right, wrong, or indifferent; a deontic principle which specifies how or to what extent the properties or states must obtain in order for (...) an action to be right, wrong, or indifferent; and finally, a specification of what is in the domain of the deontic principle. For example, mental state and desire theories provide different accounts of the first element; maximizing and satisficing are distinct deontic principles; and Act and Rule Consequentialism specify different domains over which a deontic principle ranges. A wide range of alternative theories can be generated by modifying these three elements. For example, Hedonistic Act Utilitarianism which requires that each act maximize pleasure, and Perfectionist Lifetime Minimalism which requires that each life satisfy some minimal standard of perfection are both varieties of Consequentialsm. The conceptual space Consequentialism describes is vast, versions of Consequentialism vary radically in their plausibility, and few objections count against all versions of Consequentialism.

Telling tales and reading have been a part of human activity for a very long time. We review in brief the anthropological evidence, then the emergence of the 'modern novel'. This explores in narratives the psychological reflections of the characters concerned with life circumstances including loss, abandonment, despair, illness, dying, and death. We report findings that the response of crying to a novel occurs as often as to music, not reported before: both 'move us'. We note what several critics and (...) authors imply about the imagined world of 'novel space' which emphasizes the active not passive nature of reading dramatic action, the latter being embedded and embodied within us. This touches on the mind–brain problem. We provide a brief introduction to neuroscientific work with brain imaging revealing how cerebral networks to do with theory of mind and brain structures that are the basis of our movements are involved with the very act of reading words and narratives. Emotional tearing is an exclusive attribute of Homo sapiens, and crying can have positive benefits for mental health. We argue that bibliotherapy needs greater attention than has been the case at present. We also suggest that telling tales and the 'modern novel' are closely allied to the development of the consciousness of Homo sapiens. (shrink)

The articles published in this issue of Ethical Perspectives all relate to the social and political consequences of phenomena such as uncertainty and anxiety. The biennial Multatuli Lecture, held in Leuven on May 12th, 2001, addressed this very theme. In her paper, “Anxiety and Uncertainty in Modern Society”, Mary Douglas, one of the keynote speakers at the conference, puts forward the view that certainty is only possible when uncertainty is held in check by some kind of institution. Citing examples from (...) her vast experience of various cultural systems, she argues that the loss of certainty in contemporary society, lamented by many, should hardly come as a surprise. Modern demography, technology and forms of labour have contributed to the decline of many traditional institutions, and increased the flexibility and open-endedness of our experience. Douglas realizes that a return to traditional forms of community, and hence greater certainty, is a chimera. She argues that we should rather examine our desire for greater certainty, and prepare ourselves to live with uncertainty, without regrets.In “Habit and History”, Robert Bellah recalls the distinction between elaborated and restricted speech codes — described by Mary Douglas in her book Natural Symbols — and employs it to interpret the contemporary tension between individual autonomy and social solidarity. For Bellah, the history of modernity is an account of the ever increasing dominance of personal freedom, elaborated speech codes and a critical spirit at the expense of ritual practices, loyalty to social institutions and the sense of community. He suggests that we will only succeed in building livable futures once we have given up the illusion of autonomy as something absolute. Instead of viewing elaborated code and restricted code as mutually exclusive, Bellah wishes to explore the possible complementarities between the two, while acknowledging that only the restricted code gives meaning to our lives.Any wish to eradicate the causes of anxiety takes it for granted that a society released from the throes of anxiety would be a desirable one. In his article, “Whistling in the Dark”, Rudi Visker questions this assumption, drawing on a tradition of thought that seeks to emphasize anxiety's revelatory function: anxiety, as Mary Douglas also pointed out, can teach us a valuable lesson about our situation, about the limitations human lives are subject to. Rather than a condition that is produced by identifiable causes, anxiety should be considered as something that is there from the start, and society's task would then be to give this ineradicable anxiety an acceptable outlet or structure.Many critics of modernity posit a close relationship between the decline of traditional meaning systems and the increasing discontent among certain groups within society. Recently, more empirical research is being carried out in order to ascertain whether such a relationship indeed exists. In their paper, “The Malaise of Limitlessness”, Mark Elchardus and Jessy Siongers present the results of an investigation into the influence of de-traditionalization on various indicators of social discontent and social well-being, among young people of secondary-school age in Belgium. Although the concept of a tradition, thus also `de-traditionalization', is notoriously difficult to pin down, Elchardus and Siongers find evidence to support the view that the modernization process, with its increased individual choice and greater self-reflection, has led to the loss of meaningful reference points, and that this, in turn, is associated with uncertainty and malaise. Interestingly, there is also evidence of a correlation between social malaise and various attitudes such as intolerance, authoritarianism and anti-democratic feelings.While the previous contributions hint at what might be called an ethical form of sublimation, where anxiety is contained and directed towards acceptable objectives, Duston Moore's article, “Revolutionary Eros”, raises the prospect of an explicitly political form of sublimation. In this wide-ranging commentary on Marcuse's masterwork, Eros and Civilization, Moore works out the far-reaching political and economic consequences of what at first sight would seem to be a matter for private individuals: desire and its repression by nature and culture . For Marcuse, the performance principle is only one among an entire field of alternate possibilities for directing surplus-repression. The full critical force of Marcuse's argument lies in the suggestion that there may be other ways, that surplus-repression might be transformed, thus leading to new kinds of social relations and new, as yet unimagined forms of labour.

Robert Grosseteste was one of the principal links between the thought of the twelfth century and the period of scholasticism. Born in or slightly before 1168 and educated at the cathedral school at Lincoln, whose bishop he later became, he was undoubtedly educated according to the curriculum which had been established during the earlier part of the twelfth century. His works show an intimate knowledge of the Timaeus and Calcidius's commentary, of Priscian, and of Martianus Capella's De nuptiis, writings (...) which, although they were sometimes cited, declined drastically in popularity in the thirteenth century. He also shows a better knowledge of the classical authors than one usually encounters in a scholastic theologian, and he knows and uses Eriugena's Periphyseon, although he does not cite it by name.

The 65th year of a scholar who has devoted 40 years to editing and elucidating Robert Grosseteste provides us with a collection of essays. Not surprisingly, they emanate from colleagues and former students of Richard Dales and reflect his interest, among other concerns, in Grosseteste's aspectus et affectus - range of vision and disposition of mind - those twin peaks with which the 13th century thinker helped to get Christian thought through Aristotle without mutual destruction.

This paper provides a new rationale for equating brain death with the death of the human organism, in light of well-known criticisms made by Alan D Shewmon, Franklin Miller and Robert Truog and a number of other writers. We claim that these criticisms can be answered, but only if we accept that we have slightly redefined the concept of death when equating brain death with death simpliciter. Accordingly, much of the paper defends the legitimacy of redefining death against objections, (...) before turning to the specific task of defending a new rationale for equating brain death with death as slightly redefined.
