Others must have shared my surprise at reading the two articles on this subject in the Classical Quarterly , one by Mr. P. H. Ling, writing ‘in the light of our present knowledge,’ and one by Professor H. J. Rose. Among the Hibeh Papyri is a fragment of an anthology which hereabouts contains quotations from Tragedy and Epicharmus. It gives four verses, the last of which was rightly identified by the editors Grenfell and Hunt. Of the lemma only a spot (...) of ink on a loose fibre remains. (shrink)

Open peer commentary on the target article “Who Conceives of Society?” by Ernst von Glasersfeld. Excerpt: The question I am most interested in is the question raised by von Glasersfeld as to whether Luhmann’s talk of “eigen-values” of society actually is, or is not, just a loose metaphor as von Glaserfeld maintains by emphasizing that in the society of human beings “the recursion of operations of observation or description is not governed by fixed rules, unlike the recursion of functions (...) that produce mathematical eigenwerte” . Indeed, how are we to conceive of the possible eigen-values of society? And who are we to possibly be able to conceive of possible eigen-values? (shrink)

In Word and Object Professor Quine formulated his Principle of Indeterminacy of Translation as follows:Manuals for translating one language into another can be set up in divergent ways, all compatible with the totality of speech dispositions, yet incompatible with one another. In countless places they will diverge in giving, as their respective translations of a sentence of the one language, sentences of the other language which stand to each other in no plausible sort of equivalence however loose. The firmer (...) the direct links of a sentence with non-verbal stimulation, of course, the less drastically its translations can diverge from one another from manual to manual. (shrink)

The Lunyu 論語 (Analects of Confucius), Daodejing 道德經 (Classic of the Way and Virtuosity) or Laozi 老子 (Book of Master Lao), and the Zhuangzi 莊子 (Book of Master Zhuang) have been broadly classified as representative of Confucianism (Lunyu) and Daoism (Laozi and Zhuangzi). This loose grouping, and the similarities and differences associated with these “schools” include some of the most telling and simultaneously misleading generalizations about Chinese philosophy or thought in general. These articles seek to provide an overview of (...) the relationship between Confucianism and Daoism. The first article begins before with a generalized topics based comparison of the Lunyu, Laozi and Zhuangzi. The latter two texts include their own significant differences, but I will, wherever possible, look for generalities that fit both. The major themes considered in this first part are (1) the perspectives on names (ming 名) and actualities (shi 實), (2) cultivation, learning, and what is considered natural (ziran 自然), and finally (3) conceptions of the person.

The Church of England By Law Established, in incidental payment for secular privilege, has submitted to the bonds of established clichá, in particular to the reproach that its rulers seem more concerned with the external or practical working of Anglican faith and ritual than with their intellectual definition and justification. This intellectual looseness remained unimportant in practice as long as a forceful anti–Roman spirit blew all waves of opinion in one practical direction. In time, however, that wind gradually lost force (...) and positive cross–currents of Anglican belief came to the public surface. The legislators of the sixteenth century had formulated the positive rules of the Thirty–Nine Articles and the Prayer Book in tolerantly broad language. They left no decisive teaching authority to explain their texts and to meet the challenge of shifting ritual and speculative doubt. Time has subjected both instruments to an everwidening range of individual interpretation especially since the early nineteenth century, when the Anglican monopoly of political, social and educational institutions was disputed by fresh tides of Protestant dissenters, renascent Catholics and nascent agnostics. To–day, as Mr. Cockshut wryly comments: “to throw doubt on the Anglican formularies is itself part of the Anglican tradition”. (shrink)

I deny that the world is fundamentally causal, deriving the skepticism on non-Humean grounds from our enduring failures to find a contingent, universal principle of causality that holds true of our science. I explain the prevalence and fertility of causal notions in science by arguing that a causal character for many sciences can be recovered, when they are restricted to appropriately hospitable domains. There they conform to a loose collection of causal notions that form a folk science of causation. (...) This recovery of causation exploits the same generative power of reduction relations that allows us to recover gravity as a force from Einstein's general relativity and heat as a conserved fluid, the caloric, from modern thermal physics, when each theory is restricted to appropriate domains. Causes are real in science to the same degree as caloric and gravitational forces. (shrink)

This paper, in introducing this Special Issue, proposes a place for exploring notions of wellbeing at the start of the 21st Century that are in contrast to the increasing cultural dominance of Cognitive Behavioural Therapy . An attempt is made to offer a space where we might still be able to think about how alienated we are through valuing existential notions such as experience and meaning whilst questioning other aspects such as existentialism’s inferred narcissism and the place it has come (...) to take up with regards to such aspects as psychoanalysis and the political. The postexistential would also include the post-phenomenological, where, for example, Merleau-Ponty’s notion of being open to what emerges in the between would be given primacy over Husserlian notions of intentionality. As a result, questions such as those of mystery, an unknown and an unconscious and the non-intentional can be re-examined. A third element to be explored will be the extent to which we might consider more recent ideas—for example, Saussure, Levinas, Derrida, Foucault, Lacan and Wittgenstein—without becoming too caught up in them. It is hoped by having a possible space to explore, what some would now call, our ‘wellbeing’, theoretically through post-existentialism and methodologically through post-phenomenology, that this can provide a loose base, with concerns of any further generalisation, for a greater possibility of accepting, rather than escaping, who we are.

Evolutionary Biology has two principal explananda, fit and diversity (Lewontin 1978). Natural selection theory stakes its claim to being the central unifying concept in biology on the grounds that it demonstrates both phenomena to be the consequence of a single process. By now the standard story hardly needs reiterating: Natural selection is a force that operates over a population, preserving the better fit, culling the less fit, and along the way promoting novel solutions to adaptive problems. Amundson’s historical survey of (...) the concept of adaptation captures the idea succinctly: The phenomenon of adaptation is at the core of modern evolutionary biology. Natural selection, the mechanism universally regarded as the primary causal influence on phenotypic evolutionary change, is first and foremost an explanation of adaptation. (1996: 11) At the same time, it appears that the capacity of natural selection to cause adaptations cannot account for every feature of the nature and distribution of biological form. Reason to believe this devolves from the simple fact that the bearers of biological form are organisms and a salient fact about organisms is that each faces the tribunal of the environment as a corporate entity, not as a loose aggregate of independent traits. One consequence of this fact is that at each stage of its development from egg to adult an organism must be an integrated, functioning whole. Another is that for any form to arise in an organism at a time, it must develop from the materials and processes at the organism’s disposal. The requirement of integration and the processes of development that produce it leave their distinctive marks on form. It seems reasonable, then, to suppose that one might appeal to the processes of development and the principles by which they operate in explaining the nature and distribution of biological form. (See here Gould 1977; Rose and Lauder 1996). (shrink)

We suggest that in the particular context of medical education, ethics can be considered in a similar way to other kinds of knowledge that are categorised and shaped by academics in the context of wider society. Moreover, the study of medical ethics education is translational in a manner loosely analogous to the study of medical education as adjunct to translational medicine. Some have suggested there is merit in the idea that much as translational research attempts to connect the laboratory scientist's (...) work to its implications for patient care, translational ethics focuses on bringing ethics scholarship into the sphere of personal and public action. We distinguish the term ‘translational ethics’ (the study of ethics being translated between academy, classroom and clinic) from other prominent definitions in the bioethics literature. To do this, we build off a notion of knowledge translation that focuses on the nonlinear movement of information that comes to professionals through multiple competing sources. We suggest that this knowledge, and particularly knowledge about ethics, becomes embodied by the individual. It is through a reflective practice that internally embedded ethics knowledge might be modified, and this work might be best carried out with a moral community that maintains a sense of practical wisdom. Applying this translational approach to the study of medical ethics education can be both academically relevant and practically useful. This view of translation can help bridge the evident, multidirectional relationships between research, education and performance. It might also create further opportunities to develop medical ethics education theory. (shrink)

Landauer’s principle is the loosely formulated notion that the erasure of n bits of information must always incur a cost of k ln n in thermodynamic entropy. It can be formulated as a precise result in statistical mechanics, but for a restricted class of erasure processes that use a thermodynamically irreversible phase space expansion, which is the real origin of the law’s entropy cost and whose necessity has not been demonstrated. General arguments that purport to establish the unconditional validity of (...) the law fail. They turn out to depend on the illicit formation of a canonical ensemble from memory devices holding random data. To exorcise Maxwell’s demon one must show that all candidate devices—the ordinary and the extraordinary—must fail to reverse the second law of thermodynamics. The theorizing surrounding Landauer’s principle is too fragile and too tied to a few specific examples to support such general exorcism. Charles Bennett’s recent extension of Landauer’s principle to the merging of computational paths fails for the same reasons as trouble the original principle. (shrink)

A critical note on Christopher Bartel and Jack M. C. Kwong, ‘Pluralism, Eliminativism, and the Definition of Art’, Estetika 58 (2021): 100–113. Art pluralism is the view that there is no single, correct account of what art is. Instead, art is understood through a plurality of art concepts and with considerations that are different for particular arts. Although avowed pluralists have retained the word ‘art’ in their discussions, it is natural to ask whether the considerations that motivate pluralism should lead (...) us to abandon art talk altogether; that is, should pluralism lead to eliminativism? This paper addresses arguments both for and against this move. We ultimately argue that pluralism allows one to retain the word ‘art’, if one wants it, but only in a loose, conversational sense. The upshot of pluralism is that talk of art in general cannot be asked to do theoretical and philosophical work. (shrink)

Adventure, boredom and seriousness are three perspectives on time which require each other for their definitions. Jankélévitch makes rich use of the literature of many languages and ages. These reflections and analyses have the allure of virtuosity-they dance, they surprise, they threaten to break loose from the bonds of sobriety and caution; all of which may or may not be a virtue in philosophical thinking, but it undeniably makes for lively reading.--C.

In lieu of an abstract, here is a brief excerpt of the content:Journal of the History of Philosophy 40.1 (2002) 118-119 [Access article in PDF] Book Review The Cambridge Companion to Augustine Eleonore Stump and Norman Kretzmann, editors. The Cambridge Companion to Augustine. Cambridge: Cambridge University Press, 2001. Pp. xv + 307. Cloth, $59.95. Paper, $21.95. Given the immeasurable influence of Augustine upon the Western tradition, a volume devoted to him in the Cambridge Companion Series has been long overdue. Fortunately, (...) the lacuna has been filled by a work that exhibits the quality of scholarship and clarity of presentation that has become a hallmark of this series. Ably edited by Eleonore Stump and Norman Kretzmann, it will serve admirably as a guide for students and professionals alike, with much that is of interest to seasoned Augustine scholars.As Stump tells us in her introduction, the eighteen essays of the volume are loosely grouped according to eight topics. These are philosophy of religion, metaphysics and theology, philosophy of mind, theory of knowledge, philosophy of language, ethics, political philosophy, and Augustine's influence. As is apparent from this list, the essays cut a vast swath through Augustine's corpus, though they focus on what is of greatest interest to philosophers. In addition, since Augustine did not recognize a clean division between philosophy and theology, much that we now classify as theology gets attention as well.In keeping with the aim of the series, the character of the essays is, for the most part, expository. Each author takes pains to explain the outlines of Augustine's position on the particular topic under consideration, and most do so with considerable attention to the evolution of his thought and the context in which he wrote. Christopher Kirwan's essay, for example, not only traces the development of Augustine's philosophy of language from his early De magistro and De dialectica through his mature De doctrina Christiana, but highlights those areas in which the influence of Stoic dialectic can be detected. Similarly, John Rist's essay on faith and reason includes a discussion of the relation of Augustine's views on credibilia to the Platonic tradition, and Paul Weithman's essay on political theory examines Augustine's critique of Ciceronian ideals of political society. Thus, while systematic in their exposition, the essays give due recognition to the fact that Augustine's views evolved through continual reassessment of the antique heritage in light of changing concerns and circumstances, particularly an increasing concern to articulate the foundations of a new, scripturally inspired, vision of God, humanity, and society. [End Page 118]In addition to exposition and historical analysis, many of the authors use their essays as occasions for constructive philosophical engagement. Perhaps the best of these is Stump's essay. Noting the pervasive disagreement among interpreters over Augustine's doctrine of free will, she distinguishes three positions available to defenders of free will--compatiblism, common libertarianism, and modified libertarianism--in order to bring greater conceptual clarity to the interpretive task. She then shows that in his early work, De libero arbitrio, Augustine develops an essentially libertarian position (though which form he is committed to remains ambiguous), but that this account comes into tension with his views concerning the action of grace on the will as they were later developed in opposition to the Pelagians. In itself this is not a startling claim, but Stump's analytical skills enable her to identify precisely where the tension lies, and she suggests a way that Augustine could have resolved this tension without compromising his basic commitments.If there is any quibble to be had with the volume, it is that several of the essays are too compressed. Roland Teske's essay on the soul and William Mann's essay on evil, for example, run a mere seven and nine pages each. Though informative, given the centrality of these topics to Augustine's thought, they would have been more useful had they been expanded. Because of this, the most satisfying essays are those in which the authors stretch out. Scott MacDonald's piece on the divine nature is particularly good in this regard. In... (shrink)

Cover versions form a loose but identifiable category of tracks and performances. We distinguish four kinds of covers and argue that they mark important differences in the modes of evaluation that are possible or appropriate for each: mimic covers, which aim merely to echo the canonical track; rendition covers, which change the sound of the canonical track; transformative covers, which diverge so much as to instantiate a distinct, albeit derivative song; and referential covers, which not only instantiate a distinct (...) song, but for which the new song is in part about the original song. In order to allow for the very possibility of transformative and referential covers, we argue that a cover is characterized by relation to a canonical track rather than merely by being a new instance of a song that had been recorded previously.

A three-valued propositional logic is presented, within which the three values are read as ?true?, ?false? and ?nonsense?. A three-valued extended functional calculus, unrestricted by the theory of types, is then developed. Within the latter system, Bochvar analyzes the Russell paradox and the Grelling-Weyl paradox, formally demonstrating the meaninglessness of both.

Practitioners and advocates of community food security (CFS) envision food systems that are decentralized, environmentally-sound over a long time-frame, supportive of collective rather than only individual needs, effective in assuring equitable food access, and created by democratic decision-making. These themes are loosely connected in literature about CFS, with no logical linkages among them. Clear articulation in a theoretical framework is needed for CFS to be effective as a guide for policy and action. CFS theory should delimit the level of analysis (...) (i.e., what are the boundaries of “community”); show how CFS relates to individual, household, and national food security and explain emergent properties, which are important at the community level of analysis; point to the best indicators of CFS or its lack; clarify the determinants of CFS; and clarify the stages of movement toward CFS. This theoretical base would allow researchers to develop valid and reliable measures, and allow practitioners to weigh alternative options to create strategic plans. A theoretical base also would help establish common ground with potential partners by making the connections to anti-hunger work, sustainable agriculture, and community development clear. (shrink)

Near the end of his speech, Timaeus outlines a theory of bodily health and disease which has seemed to many commentators loosely unified or even inconsistent . But this section is better unified than it has appeared, and gives us at least one important insight into the workings of physical causality in the Timaeus. I argue first that the apparent disorder in Timaeus’s theory of disease is likely a deliberate effect planned by the author. Second, the taxonomy of disease in (...) the passage consists of one genus subsuming two species. Third, in Timaeus’s theory, health lies between perfect stability and a chaos of all possible motions; this indicates a conception of health as the activation of the body's powers in the right way. A power is a property directed towards bringing about some change. Fourth, the activation of these powers can change depending on the location of their possessors. This last point shows that causation among the physical items in the Timaeus involves structures as well as pushes. (shrink)

In lieu of an abstract, here is a brief excerpt of the content:The Origins and Evolution of Bioethics: Some Personal ReflectionsEdmund D. Pellegrino (bio)AbstractBioethics was officially baptized in 1972, but its birth took place a decade or so before that date. Since its birth, what is known today as bioethics has undergone a complex conceptual metamorphosis. This essay loosely divides that metamorphosis into three stages: an educational, an ethical, and a global stage. In the educational era, bioethics focused on a (...) perceived “dehumanization” of medicine by the rising power of science and technology. Remedies were sought by introducing humanities, ethics, and human “values” into the medical curriculum. Ethics was one among the humanistic disciplines, but not the dominant one. In the second era, ethics assumed a dominant role as ever more complex dilemmas emerged from the rapid pace of biological research. As such dilemmas were applied to medical practice, the need for a more rigorous and more formal analysis of their moral status was clear. Philosophically-trained ethicists had an obvious role. They began to teach, write, and profoundly influence medical education and practice. In the third—and present—period, the breadth of problems has become so broad that ethicists must, themselves, draw on disciplines well beyond their expertise—e.g., law, religion, anthropology, economics, political science, psychology, and the like. The era of bioethics as a global enterprise is upon us. The original hope for humanizing medicine has not been overtly successful; however, much has been accomplished of value to patients, the profession, and society. Medical morality has been transformed into a formal, systematic study of a whole range of issues of the greatest significance to humanity. Now the major challenge is one of identity, or inter-relationships and connections between the theoretical and the practical. Bioethics has outgrown its beginnings.I have been invited to give a “personal recollection” of the early development of bioethics. Such invitations are notoriously hard to resist, but also problematic when they are the recollections of a participant [End Page 73] in the events to be described. We need only be reminded of the vagaries common to the plethora of memoirs on the book stands today. Few have escaped the perils of selective memory, self-promotion, or the settling of old scores. Yet their perils notwithstanding, memoirs may serve some useful purpose. They are the raw material—verbal kitchen middens so to speak—out of which historians can later sift fact from fancy. They enable “tribal elders” to give witness to the past from which the present can fashion some sense of continuity.I will organize my reflections around three very arbitrary time periods that represent my own way of thinking about the evolution of bioethics: (1) an era of “proto-bioethics” (1960–1972), (2) an era of philosophical bioethics (1972–1985), and (3) an era of global bioethics (1985-present). Each era, of course, overlaps with the others, and the dominant strand of each runs through the others as well.In the proto-bioethics period, the language of human values predominated; in the era of bioethics philosophically construed, it was the language of philosophical ethics; and in the era of bioethics globally construed, the social and behavioral sciences have gained greater prominence. In each period, interest in the traditional humanities other than philosophy waxed and waned. In the earlier years, religion and theology predominated. Beginning in the 1970s, philosophy took a dominant role. In the last two decades, other disciplines, like law, literature, and the social sciences, have exerted more and more influence (McNeur 1963; Pellegrino 1997; Barker 1987).I make no pretense here of writing any part of the formal “history” of bioethics. Works of this nature are beginning to appear (Rothman 1991; Jonsen 1998 ; Dell’Oro and Viafora 1996). Thomas McElhinney and I are preparing our own account of the work and influence of the Institute on Human Values in Medicine, one of the influential programs of the Society for Health and Human Values (Pellegrino and McElhinney, n.d.). Space limitations as well as prudence preclude any attempt to do justice to all the events, institutions, and people who have made the field of bioethics what it is today. I apologize for these omissions, for any unintentional lapses of... (shrink)

Bainbridge’s well known “Ironies of Automation” Analysis, design and evaluation of man–machine systems. Elsevier, Amsterdam, pp 129–135, 1983. https://doi.org/10.1016/B978-0-08-029348-6.50026-9) laid out a set of fundamental criticisms surrounding the promises of automation that, even 30 years later, remain both relevant and, in many cases, intractable. Similarly, a set of ironies in technologies for sensor driven self-quantification is laid out here, spanning from instrumental problems in human factors design to much broader social problems. As with automation, these ironies stand in the way (...) of many of the promised benefits of these wearable technologies. It is argued here that without addressing these ironies now, the promises of wearables may not come to fruition, and instead users may experience outcomes that are opposite to those which the designers seek to afford, or, at the very least, those which consumers believe they are being offered. This paper describes four key ironies of sensor driven self-quantification: know more, know better versus no more, no better; greater self-control versus greater social control; well-being versus never being well enough; more choice versus erosion of choice.

The author of this study aims to provide a synthetic survey of Diderot’s philosophy, as distinguished from the numerous analytic studies that have been made of particular aspects of the Frenchman’s thought. The central thread uniting Diderot’s various works, Crocker contends, is a view of the universe as comprising simultaneously both order and disorder in an ineluctable tension. In the initial chapter, Crocker outlines this rather loose theme by examining Diderot’s "dynamic" conception of the physical universe and man’s ambiguous (...) relation to it. The theme is elucidated in succeeding chapters devoted, respectively, to Diderot’s aesthetic theories, his view of morality, and his political thought. Crocker stresses the evolution of Diderot’s thought on these subjects as a consequence of the very intractability of the central problem that concerned him. Although Diderot often contradicted himself, the author concludes, his self-contradictions were a reflection of the contradictory nature of reality as perceived by both Diderot and the author.

Lexical Semantics is about the meaning of words. Although obviously a central concern of linguistics, the semantic behaviour of words has been unduly neglected in the current literature, which has tended to emphasize sentential semantics and its relation to formal systems of logic. In this textbook D. A. Cruse establishes in a principled and disciplined way the descriptive and generalizable facts about lexical relations that any formal theory of semantics will have to encompass. Among the topics covered in depth are (...) idiomaticity, lexical ambiguity, synonymy, hierarchical relations such as hyponymy and meronymy, and various types of oppositeness. Syntagmatic relations are also treated in some detail. The discussions are richly illustrated by examples drawn almost entirely from English. Although a familiarity with traditional grammar is assumed, readers with no technical linguistic background will find the exposition always accessible. All readers with an interest in semantics will find in this original text not only essential background but a stimulating new perspective on the field. (shrink)

As humans, we frequently engage in mental time travel, reliving past experiences and imagining possible future events. This study examined whether similar factors affect the subjective experience associated with remembering the past and imagining the future. Participants mentally “re-experienced” or “pre-experienced” positive and negative events that differed in their temporal distance from the present , and then rated the phenomenal characteristics associated with their representations. For both past and future, representations of positive events were associated with a greater feeling of (...) re-experiencing than representations of negative events. In addition, representations of temporally close events contained more sensorial and contextual details, and generated a stronger feeling of re-experiencing than representations of temporally distant events. It is suggested that the way we both remember our past and imagine our future is constrained by our current goals. (shrink)

A comprehensive introduction to the ways in which meaning is conveyed in language. Alan Cruse covers semantic matters, but also deals with topics that are usually considered to fall under pragmatics. A major aim is to highlight the richness and subtlety of meaning phenomena, rather than to expound any particular theory. Rich in examples and exercises, Meaning in Language provides an invaluable descriptive approach to this area of linguistics for undergraduates and postgraduates alike.

Live donor kidney transplantation is the best treatment option for most patients with late-stage chronic kidney disease; however, the rate of living kidney donation has declined in the United States. A consensus conference was held June 5-6, 2014 to identify best practices and knowledge gaps pertaining to live donor kidney transplantation and living kidney donation. Transplant professionals, patients, and other key stakeholders discussed processes for educating transplant candidates and potential living donors about living kidney donation; efficiencies in the living donor (...) evaluation process; disparities in living donation; and financial and systemic barriers to living donation. We summarize the consensus recommendations for best practices in these educational and clinical domains, future research priorities, and possible public policy initiatives to remove barriers to living kidney donation.

Although Kierkegaard's writings have not exerted an essential influence on canonical trends in literary criticism and theory, his work has supplied subtle and important inspiration for numerous eminent literary critics and theorists. Kierkegaard's influence transcends many polemics in literary theory—a claim justified by the fact that literary critics who draw significant examples and authority from Kierkegaard support varied and sometimes greatly conflicting philosophical and moral positions. This chapter argues that literary‐critical topics invested in Kierkegaard's texts and ideas can be grouped (...) loosely under three thematic banners: irony, repetition, and silence. These themes are often pursued with reference to Kierkegaard's On the Concept of Irony, Repetition, and Fear and Trembling, respectively. The chapter discusses key examples from each of the three common themes, and indicates some of the important exceptions to this typology. (shrink)

The words χρxs22EF and δεxs1FD6 with their inflectional and dialectic variations, are less definite and stable in their semantic range than the other Greek expressions for the general ideas of necessity, obligation, or propriety. Their semantic boundaries varied with the dialect, province of literature, and period–which cannot, indeed, be entirely separated. From Homer to Aristotle there is a steady trend, so plain that the slight notice taken of it is rather surprising. Everyone sees that the two are sometimes differentiated; yet (...) it seems to be loosely taken for granted that they are substantially equivalent, and that either may, almost anywhere, be taken as an equivalent of the verbal in -τxs22EFος. The statements in Liddell and Scott under χρxs22EF present an admirable confusion of all periods and styles, and J. H. H. Schmidt, with no mention of dates, makes a distinction that resembles a reversal of the true relation. (shrink)

Natural selection is commonly seen not just as an explanation for adaptive evolution, but as the inevitable consequence of “heritable variation in fitness among individuals”. Although it remains embedded in biological concepts, such a formalisation makes it tempting to explore whether this precondition may be met not only in life as we know it, but also in other physical systems. This would imply that these systems are subject to natural selection and may perhaps be investigated in a biological framework, where (...) properties are typically examined in light of their putative functions. Here we relate the major questions that were debated during a three-day workshop devoted to discussing whether natural selection may take place in non-living physical systems. We start this report with a brief overview of research fields dealing with “life-like” or “proto-biotic” systems, where mimicking evolution by natural selection in test tubes stands as a major objective. We contend the challenge may be as much conceptual as technical. Taking the problem from a physical angle, we then discuss the framework of dissipative structures. Although life is viewed in this context as a particular case within a larger ensemble of physical phenomena, this approach does not provide general principles from which natural selection can be derived. Turning back to evolutionary biology, we ask to what extent the most general formulations of the necessary conditions or signatures of natural selection may be applicable beyond biology. In our view, such a cross-disciplinary jump is impeded by reliance on individuality as a central yet implicit and loosely defined concept. Overall, these discussions thus lead us to conjecture that understanding, in physico-chemical terms, how individuality emerges and how it can be recognised, will be essential in the search for instances of evolution by natural selection outside of living systems.

Objectives: To discover the current state of opinion and practice among doctors in Victoria, Australia, regarding end-of-life decisions and the legalisation of voluntary euthanasia. Longitudinal comparison with similar 1987 and 1993 studies.Design and participants: Cross-sectional postal survey of doctors in Victoria.Results: 53% of doctors in Victoria support the legalisation of voluntary euthanasia. Of doctors who have experienced requests from patients to hasten death, 35% have administered drugs with the intention of hastening death. There is substantial disagreement among doctors concerning the (...) definition of euthanasia.Conclusions: Disagreement among doctors concerning the meaning of the term euthanasia may contribute to misunderstanding in the debate over voluntary euthanasia. Among doctors in Victoria, support for the legalisation of voluntary euthanasia appears to have weakened slightly over the past 17 years. Opinion on this issue is sharply polarised. (shrink)

Britain has the highest rate of pregnancies in Europe among young women aged 15–19 years. In girls under 16, the rates of pregnancy are rising: in 2006, there were 7.8 conceptions per 1000 girls; in 2007, there were 8.3 conceptions per 1000 girls. Where babies are born with conditions requiring treatment, the clinician may be faced with the task of obtaining consent from a parent who is also a minor. These situations present potential pitfalls. Guidance from legislative acts and case (...) law is sparse. For example, the Children Act 1989 does not specify age limits for the assumption of parental responsibility. Legal precedents for assessing competence and capacity may not apply to minors. The Gillick principle for assessing competence does not extend to the competence of minors to take decisions as responsible parents. The Mental Capacity Act 2005 prescribes the limits of capacity but only in those aged over 16 years. Lastly, although a minor's parents will bear responsibility for the minor, this responsibility does not extend to the minor's child. This article explores these controversies through four case scenarios. These scenarios are loosely based on the authors' prior experiences as paediatric surgeons. In light of current statutory guidance, and the paucity of legal precedent, there are few answers to be offered. However, exploring the issues, enabling them to be thoughtfully considered by health professionals, is in itself valuable. (shrink)

Primordial emotions are the subjective element of the instincts which are the genetically programmed behaviour patterns which contrive homeostasis. They include thirst, hunger for air, hunger for food, pain and hunger for specific minerals etc.There are two constituents of a primordial emotion—the specific sensation which when severe may be imperious, and the compelling intention for gratification by a consummatory act. They may dominate the stream of consciousness, and can have plenipotentiary power over behaviour.It is hypothesized that early in animal evolution (...) complex reflex mechanisms in the basal brain subserving homeostatic responses, in concert with elements of the reticular activating system subserving arousal, melded functionally with regions embodied in the progressive rostral development of the telencephalon. This included the emergent limbic and paralimbic areas, and the insula. This phylogenetically ancient organization subserved the origin of consciousness as the primordial emotion, which signalled that the organisms existence was immediately threatened. Neuroimaging confirms major activations in regions of the basal brain during primordial emotions in humans. The behaviour of decorticate humans and animals is discussed in relation to the possible existence of primitive awareness.Neuroimaging of the primordial emotions reveals that rapid gratification of intention by a consummatory act such as ingestion causes precipitate decline of both the initiating sensation and the intention. There is contemporaneous rapid disappearance of particular regions of brain activation which suggests they may be part of the jointly sufficient and severally necessary activations and deactivations which correlate with consciousness [Crick, F. & Koch, C. .
