Despite many attempts to achieve an adequate definition of living systems by means of a set of necessary and sufficient conditions, the opinion that such an enterprise is inexorably destined to fail is increasingly gaining support. However, we believe options do not just come down to either having faith in a future success or endorsing skepticism. In this paper, we aim to redirect the discussion of the problem by shifting the focus of attention from strict definitions towards a philosophical framework (...) that allows conceiving of living systems as a natural kind, but whereby natural kinds are not to be defined by fixed necessary and sufficient conditions. We argue for a property-cluster kind approach according to which living systems constitute a natural kind with vague boundaries, capable of changing, and whose members do not need to instantiate every property. We draw from Boyd’s homeostatic property-cluster theory and introduce two modifications, one regarding homeostatic mechanisms and another related to the scientific role of kinds. Thus, our view overcomes some difficulties of Boyd’s theory and we are able to account for the natural kindhood of living things. We also emphasize the most appealing features of our approach for specific research fields and address three objections to this sort of approach. (shrink)

This paper contemplates Organicism and its relation with molecular and evolutionary biology. We explore whether twentieth-first century biology is returning to positions held at the beginning of the twentieth century and then abandoned. The guiding line is a history of theoretical biology in which we distinguish three periods: 1. The 20s-30s, and the Theoretical Biology Club (Needham, Woodger, and Waddington, among others); 2. An intermediate period in the 60s-70s, in which, in spite of the eclosion of the molecular and evolutionary (...) biologies, there is some recovery of organicist positions, and 3. The present post-genomic situation, which is demanding a systemic approach. (shrink)

Michael J. Zimmerman explores whether and how our ignorance about ourselves and our circumstances affects what our moral obligations and moral rights are. He rejects objective and subjective views of the nature of moral obligation, and presents a new case for a 'prospective' view.

Much has been published about the ethical issues encountered by clinicians in genetics/genomics, but those experienced by clinical laboratory scientists are less well described. Clinical laboratory scientists now frequently face navigating ethical problems in their work, but how they should be best supported to do this is underexplored. This lack of attention is also reflected in the ethics tools available to clinical laboratory scientists such as guidance and deliberative ethics forums, developed primarily to manage issues arising within the clinic.We explore (...) what ethical issues are being experienced by clinical scientists, how they think such issues could be best analysed and managed, and whether their practice might be enhanced by more situated approaches to ethics deliberation and practice such as ethical preparedness. From thematic analysis of cases presented by clinical scientists at a specially convened meeting of the UK Genethics Forum, we derived three main ethical themes: (1) the redistribution of labour and responsibilities resulting from the practice of genomic medicine; (2) the interpretation and certainty of results and (3) the proposal that better standardisation and consistency of ethical approaches (for example, more guidelines and policy) could resolve some of the challenges arising.We argue that although standardisation is important for promoting shared understandings of good (including ethical) practice, supplementary approaches to enhance and sustain ethical preparedness will be important to help clinical scientists and others in the recently expanded genetic/genomic medicine environment foster quality ethical thinking.

This essay is written on the following premises and argues for them. “Enlightenment” is a word or signifier, and not a single or unifiable phenomenon which it consistently signifies. There is no single or unifiable phenomenon describable as “the Enlightenment,” but it is the definite article rather than the noun which is to be avoided. In studying the intellectual history of the late seventeenth century and the eighteenth, we encounter a variety of statements made, and assumptions proposed, to which the (...) term “Enlightenment” may usefully be applied, but the meanings of the term shift as we apply it. The things are connected, but not continuous; they cannot be reduced to a single narrative; and we find ourselves using the word “Enlightenment” in a family of ways and talking about a family of phenomena, resembling and related to one another in a variety of ways that permit of various generalizations about them. We are not, however, committed to a single root meaning of the word “Enlightenment,” and we do not need to reduce the phenomena of which we treat to a single process or entity to be termed “the” Enlightenment. It is a reification that we wish to avoid, but the structure of our language is such that this is difficult, and we will find ourselves talking of “the French” or “the Scottish,” “the Newtonian” or the “the Arminian” Enlightenments, and hoping that by employing qualifying adjectives we may constantly remind ourselves that the keyword “Enlightenment” is ours to use and should not master us.

Herein, we report an unusual case of a 58-year-old woman who experienced acute rejection at 30 months after OLT, only one case in which HNKHC resulted in MP (...) pulse therapy for acute rejection in all 913 recipients in our center. The general morbidity of HNKHC was 1.09‰ in this study. HNKHC is characterized by rapid onset, rapid progression, and a lack of specific clinical manifestations. High-dose MP management was a clear risk factor. The principle of treatment included rapid rehydration, low-dose insulin infusion, and correcting disorders of electrolytes and acidosis. In conclusion, clinicians considering MP pulse therapy after OLT should be alert to the occurrence of HNKHC. Keywords: liver transplantation, complications, hyperosmolar nonketotic hyperglycemic coma, methylprednisolone pulse therapy, principle of treatment. (shrink)

This manuscript reports on a landmark symposium on the ethical, legal and technical challenges of xenotransplantation in the UK. King’s College London, with endorsement from the British Transplantation Society (BTS), and the European Society of Organ Transplantation (ESOT), brought together a group of experts in xenotransplantation science, ethics and law to discuss the ethical, regulatory and technical challenges surrounding translating xenotransplantation into the clinical setting. The symposium was the first of its kind in the UK for 20 years. This paper (...) summarises the content of the expert lectures showcasing the progress which has been made in xenotransplantation including—the history of xenotransplantation, advances in gene edited animals and progress towards clinical xenotransplantation. We then set out the ethical and legal issues still to be resolved. Finally, we report the themes of the roundtable discussion highlighting areas of consensus and controversy. While the detail of the legal discussion was directed towards the UK, the principles and summary reported here are intended to be applicable to any jurisdiction seeking to implement clinical xenotransplantation.

J.N. Findlay was a South African philosopher who published from the late 1940s into the 1980s. He had a prestigious international academic career, holding many academic posts around the world. This article uses a textual comparative approach and focuses on Findlay’s Gifford Lecture at St Andrews University between 1965 and 1970. The objective of the article is to highlight the extent to which Findlay’s philosophical writings were influenced by Mahāyāna Buddhism. Although predominantly a Platonist, Findlay drew influence from Asian philosophy (...) and religion, particularly Mahāyāna Buddhism. In these lectures, he applies the metaphor of the Platonic Cave to investigate Hegelian and Husserlian approaches to knowledge. Though he was a leading Hegel and Husserl scholar, his reading of these two philosophers is strongly influenced by Mahāyāna Buddhism, resulting in a unique mystical interpretation of these two philosophers. Revisiting Findlay’s writings is significant for two reasons; firstly, he investigated Buddhism prior to the Asian religions being included in Religious Studies departments’ purview in South African universities, and secondly, his interpretation of two prominent Western philosophers along Buddhist lines provides an early attempt at decolonising the predominance of Western philosophical views of knowledge.Contribution: This contribution forms part of a larger collection of essays investigating philosophical works that have had a significant impact on the study of religion. This contribution investigates the Buddhist influence on J.N. Findlay’s philosophical readings of Husserl and Hegel. (shrink)

On its first appearance in 1960, J.O. Urmson's Concise encyclopedia of Western philosophy and philosophers established itself as a classic. Its contributors included many of the leading philosophers of the English-speaking world: Ryle, Hare, Strawson, Ayer, Dummett, Williams and many others. They wrote with an authority and individuality which made the Encyclopedia into a lively and engaging introduction to philosophy as well as a convenient reference work. For this edition, supervised by Jonathan Rée, the original articles have been revised and (...) updated, and eighty articles by thirty one new authors have been added. The additions take account of recent developments in philosophy, of literary, historical and political issues in philosophy, and of developments in continental thought, including in Marxism, psychoanalysis, phenomenology, existentialism, structuralism, post-structuralism and deconstruction. There is a clear, integral cross-referencing system which allows the reader to identify points of overlap between philosophical traditions and their personalities at a glance. (shrink)

Despite its uniform appearance, the cerebellar cortex is highly heterogeneous in terms of structure, genetics and physiology. Purkinje cells (PCs), the principal and sole output neurons of the cerebellar cortex, can be categorized into multiple populations that differentially express molecular markers and display distinctive physiological features. Such features include action potential rate, but also their propensity for synaptic and intrinsic plasticity. However, the precise molecular and genetic factors that correlate with the differential physiological properties of PCs remain elusive. In this (...) article, we provide a detailed overview of the cellular mechanisms that regulate PC activity and plasticity. We further perform a pathway analysis to highlight how molecular characteristics of specific PC populations may influence their physiology and plasticity mechanisms. (shrink)

In recent years the issue of whether mysticism can be induced by drugs has been pursued by both scholars of mystical literature and psychological researchers. R. C. Zaehner is perhaps the best known among the scholars of religious literature who have addressed the issues of drug-induced mysticism. While on the side of empirical psychology investigators such as Walter N. Pahnke, R. E. L. Masters, and Jean Houston have pursued some of the same issues using the techniques of laboratory experimentation. Zaehner, (...) who was familiar with both Eastern and Western mysticism, argued that drug-induced experiences are not the same as religious mystical experiences of the theistic variety. It was farcical, he argued, for Aldous Huxley to posit a connection between his preternatural feeling of oneness with his chair and the Beatific Vision. The issue between Zaehner and Huxley was not over the veridicality of Huxley's mystical experience. It was over the significance of Huxley's experience: Was it or was it not a drug-induced mystical experience of the sort attained by mystics after heroic struggles of self-discipline? This was the issue again when Zaehner came to address himself to the claims of Timothy Leary, a chief proponent of ‘the LSD experience’, and, in general terms, this has been the central issue pursued by the psychological researchers.
