Among the abilities people fear they will lose as they age, the most frequently reported is "staying sharp". The fear of being afflicted with Alzheimer's disease and other dementing disorders, which will clinically impact 10 to 12% of the population between the age of 65 and death, is the major concern. Despite the fear of losing their minds, most persons will not develop Alzheimer's disease. So why does the fear of losing mental acuity top the AARP list?One reason is that (...) older adults in general cannot distinguish the usual changes with aging from neurocognitive disorders such as Alzheimer's disease. We also live in a society that has been labeled, among other things... (shrink)

One of Hume's most well-known works and a masterpiece of philosophy, A Treatise of Human Nature is indubitably worth taking the time to read.

This study investigates the performance of psychopathic individuals on tasks believed to be sensitive to dorsolateral prefrontal and orbitofrontal cortex (OFC) functioning. Psychopathic and non-psychopathic individuals, as defined by the Hare psychopathy checklist revised (PCL-R) [Hare, The Hare psychopathy checklist revised, Toronto, Ontario: Multi-Health Systems, 1991] completed a gambling task [Cognition 50 (1994) 7] and the intradimensional/extradimensional (ID/ED) shift task [Nature 380 (1996) 69]. On the gambling task, psychopathic participants showed a global tendency to choose disadvantageously. Specifically, they showed an (...) impaired ability to show learning over the course of the task. On the ID/ED task, the performance of psychopathic individuals was not significantly different from incarcerated controls on attentional set-shifting, but significant impairments were found on response reversal. These results are interpreted with reference to an OFC and amygdala dysfunction explanation of psychopathy. (shrink)

In mill the principle of utility does not ascribe rightness or wrongness to anything. It governs not just morality but the whole art of life. It says that happiness is the only thing desirable as an end. But the meaning of this formulation is problematic, Since mill's theory of practical reason conceives this desirability as an end as generating reasons for action for all agents in a way implying impartiality between self and others, Whereas in the ordinary sense it does (...) not. This interpretation is supported by detailed textual analysis. (shrink)

The concept of brain birth has assumed a position of some significance in discussions on the status of the human embryo and on the point in embryonic development prior to which experimental procedures may be undertaken on human embryos. This paper reviews previous discussions of this concept, which have placed brain birth at various points between 12 days' and 20 weeks' gestation and which have emphasised the symmetry of brain birth and brain death. Major developmental features of brain development are (...) outlined, including the gradualness with which new features generally appear, and also the electroencephalogram (EEG) characteristics of premature infants. From this it is concluded that, if the concept of brain birth is a valid one, it should be placed at 24-28 weeks' gestation. More importantly, it is concluded that the differences between brain development and brain death throw doubt on the concept itself. (shrink)

Human dignity has long been used as a foundational principle in policy documents and ethical guidelines intended to govern various forms of biomedical research. Despite the vast amount of literature concerning human dignity and embryonic tissues, the majority of biomedical research uses non-embryonic human tissue. Therefore, this contribution addresses a notable lacuna in the literature: the relationship, if any, between human dignity and human tissue. This paper first elaborates a multidimensional understanding of human dignity that overcomes many of the shortcomings (...) associated with the use of human dignity in other ethical debates. Second, it discusses the relationship between such an understanding of human dignity and ‘non-embryonic’ human tissue. Finally, it considers the implications of this relationship for biomedical research and practice involving human tissue. The contribution demonstrates that while human tissue cannot be said to have human dignity, human dignity is nevertheless implicated by human tissue, making what is done with human tissue and how it is done worthy of moral consideration.

Physicalists motivate their position by posing a problem for the opposition: given the causal completeness of physics and the impact of the mental (or, more broadly, the seemingly nonphysical) on the physical, antiphysicalism implies that causal overdetermination is rampant. This argument is, however, equivocal in its use of 'physical'. As Scott Sturgeon has recently argued, if 'physical' means that which is the object of physical theory, completeness is plausible, but the further claim that the mental has a causal impact on (...) the physical is no longer so evident. In this paper I assess the damage due to the ambiguity of 'physical' and provide a repair to the overdetermination strategy. (shrink)

The furore over the retention of organs at postmortem examination, without adequate consent, has led to a reassessment of the justification for, and circumstances surrounding, the retention of any human material after postmortem examinations and operations. This brings into focus the large amount of human material stored in various archives and museums, much of which is not identifiable and was accumulated many years ago, under unknown circumstances. Such anonymous archival material could be disposed of, used for teaching, used for research, (...) or remain in storage. We argue that there are no ethical grounds for disposing of the material, or for storing it in the absence of a teaching or research rationale. Nevertheless, with stringent safeguards, it can be used even in the absence of consent in research and teaching. Regulations are required to control the storage of all such human material, along the lines of regulations governing anatomy body bequests. (shrink)

Susan Schneider argues that the entities to be identified as part of the 'physical base' for physicalism must be in part abstract and that this fact either falsifies physicalism or renders it so problematic as to be 'no physicalism worth having'. I accept the abstractness of the entities but argue both that physicalism is consistent with such and that none of the alleged problems for Platonistic physicalism are serious.

Christopher Miles Coope offers a letter, drafted by Helen Taylor but certified by Mill, in which Mill asserts the duty to vote, as evidence that he could not have regarded harmfulness to others as a necessary condition of moral wrongness. But it is clear that Mill regarded the duty to vote as one of imperfect obligation, and the wrongness of not fulfilling it as a matter roughly of not doing enough, in this case not doing one's fair share. He has (...) room for the common-sense harmlessness of staying at home. At the same time he grounds political duties in the harmfulness of neglecting the power of legislation and in the possibility, consistently maintained, that one can harm by inaction. Mill's view, central to his relation between morality and liberty, remains at work here, while also suggesting reflections on the peculiarity of his conception of harm. (shrink)

The latter half of the eighteenth century saw radical changes in the way nature - both external and human nature - was perceived. It is these new perceptions, these new images of the 'the natural' that this book examines: new appreciations of the 'sublime' wildness of landscape; new revelations by the life sciences of natural creative fecundity; new assertions of the innocence of 'natural man', as illustrated by the noble savage, the contented peasant, the happy family; a new sense of (...) harmony between man and nature, reflected in changing moral, psychological, economic, and religious attitudes. Professor Charlton concentrates on French examples, for in France the contrast between old and new views was particularly vivid; but there are also numerous comparisons with England and other European countries, making this a major study in the cultural history of Europe at an especially crucial time for the formation of many of our modem assumptions about man and nature.

J. Angelo Corlett’s response to Leigh Turner defends the current practice of anonymous refereeing in scholarly journals. In reply to him: a slightly refined proposal for signed referees’ reports, with temporarily blind refereeing, would restore to the process of publication, in philosophy at least, the sense of responsibility for rational debate, cooperation, mutual criticism, and simple courtesy which is expected among colleagues in public academic relations, and would also allow more credit for the difficult task for refereeing. Personal observation of (...) the quality of referees’ reports suggests that a gathering of anecdotal evidence would show the need for reform. (shrink)

Revisionist interpretation of Mill needs to be extended to deal with a residue of puzzles about his moral theory and its connection with his theory of liberty. The upshot shows his reinterpretation of his Benthamite tradition as a form of ‘philosophical utilitarianism’; his definition of the art of morality as collective self-defence; his ignoring of maximization in favour of ad hoc dealing in utilities; the central role of his account of the justice of punishment; the marginal role of the internal (...) sanction in his criterion of moral wrong; his deep respect for common-sense morality; and his restriction of the scope of morality so as to claim for the utilitarian tradition the whole realm of the aesthetics of conduct as part of a general theory of practical reason.

Several recent papers which purport to substantiate or negate arguments in favor of certain theories of absolute space have been based on fallacious principles. In this paper we discuss three related instances, indicating where misconceptions have arisen. We establish, contrary to popular belief, that the classical Lorentz ether theory accounts for all the experimental evidence which supports the special theory of relativity. We demonstrate that the ether theory predicts the null results obtained from pulsar timing and Mössbauer experiments. We conclude (...) that a measurement of the one-way velocity of light has physical meaning within the context of the Lorentz theory, and argue that an adequately designed experiment to measure the one-way velocity of light should be attempted.

The possible symmetry between the concepts of brain death and brain birth (life) is explored. Since the symmetry argument has tended to overlook the most appropriate definition of brain death, the fundamental concepts of whole brain death and higher brain death are assessed. In this way, a context is provided for a discussion of brain birth. Different writers have placed brain birth at numerous points: 25-40 days, eight weeks, 22-24 weeks, and 32-36 weeks gestation. For others, the concept itself is (...) open to question. Apart from this, it needs to be asked whether a unitary concept is an oversimplification. The merits of defining two stages of brain birth, to parallel the two definitions of brain death, are discussed. An attempt is then made to map these various stages of brain birth and brain death onto a developmental continuum. Although the results hold biological interest, their ethical significance is less evident. Development and degeneration are not interchangeable, and definitions of death apply specifically to those who are dying, not those who are developing. I conclude that while a dual concept of brain death has proved helpful, a dual concept of brain birth still has problems, and the underlying concept of brain birth itself continues to be elusive.
