One of the theses defended by Aristotle in Nicomachean Ethics books VII and X is that pleasure is good or is one of the good things : and Aristotle thinks that it follows from this that the best thing is a pleasure, or is pleasure in a certain way. Among his arguments for the latter we find the following:The fact that all things, both brutes and men, pursue pleasure is an indication that the best thing is in a certain way (...) that. (shrink)

Computer users are often the last line of defense in computer security. However, with repeated exposures to system messages and computer security warnings, neural and behavioral responses show evidence of habituation. Habituation has been demonstrated at a neural level as repetition suppression where responses are attenuated with subsequent repetitions. In the brain, repetition suppression to visual stimuli has been demonstrated in multiple cortical areas, including the occipital lobe and medial temporal lobe. Prior research into the repetition suppression effect has generally (...) focused on a single repetition and has not examined the pattern of signal suppression with repeated exposures. We used complex, everyday stimuli, in the form of images of computer programs or security warning messages, to examine the repetition suppression effect across repeated exposures. The use of computer warnings as stimuli also allowed us to examine the activation of learned fearful stimuli. We observed widespread linear decreases in activation with repeated exposures, suggesting that repetition suppression continues after the first repetition. Further, we found greater activation for warning messages compared to neutral images in the anterior insula, pre-supplemental motor area, and inferior frontal gyrus, suggesting differential processing of security warning messages. However, the repetition suppression effect was similar in these regions for both warning messages and neutral images. Additionally, we observed an increase of activation in the default mode network with repeated exposures, suggestive of increased mind wandering with continuing habituation. (shrink)

: The purpose of this paper and its sister paper I (Farrell and Hooker, a) is to present, evaluate and elaborate a proposed new model for the process of scientific development: self-directed anticipative learning. The vehicle for its evaluation is a new analysis of a well-known historical episode: the development of ape language research. Paper I examined the basic features of SDAL in relation to the early history of ape-language research. In this second paper we examine the reconceptualization of ape-language (...) research following what many conceived to be Terrace's refutation of ape-language. We show that the apparent 'revolution' in our understanding of ape linguistic capacities was not based upon 'revolutionary' research different in kind from 'normal' research. The same processes of self-directed interactive exploration of possibility space, that enables a homing-in upon both error and success, is present in all phases of productive science. Moreover, conceiving science as an SDAL process explains how scientists learn how to learn about their research domain. (shrink)

This article presents the first results of a study of the decisions made by health professionals in South Australia concerning the management of death, dying, and euthanasia, and focuses on the findings concerning the attitudes and practices of medical practitioners. Mail-back, self-administered questionnaires were posted in August 1991 to a ten per cent sample of 494 medical practitioners in South Australia randomly selected from the list published by the Medical Board of South Australia. A total response rate of 68 per (...) cent was obtained, 60 per cent of which (298) were usable returns. It was found that forty-seven per cent had received requests from patients to hasten their deaths. Nineteen per cent had taken active steps which had brought about the death of a patient. Sixty-eight per cent thought that guidelines for withholding and withdrawal of treatment should be established. Forty-five per cent were in favour of legalisation of active euthanasia under certain circumstances. (shrink)

Health care professionals’ and trainees’ conceptions of their responsibilities to patients can change over time for a number of reasons: evolving career goals, desires to serve different patient populations, and changing family obligations, for example. Some changes in conceptions of responsibility are healthy, but others express moral damage. Clinicians’ changes in their conceptions of what they are responsible for express moral damage when their responses to others express a meager, rather than robust, sense of what they owe others. At least (...) two important expressions of moral damage in the context of health care are these: callousness and divestiture. Callousness describes the poor condition of a clinician's capacity for moral perception; when her capacity to accurately appreciate features of moral relevance that configure others’ needs, vulnerabilities, and desert of care diminishes, such that she fails to respond with care to those for whom she has duties to care, she is callous. Callousness has been explored in detail elsewhere,1 and so the focus of this paper is divestiture. A clinician divests when the value of responding with care to others becomes less centrally and importantly constitutive of his personal and professional identity. Divestiture has important consequences for patients and health professions education, which I will explore here. (shrink)

The sporadic nature of Alzheimer's disease argues for an environmental link that may drive AD pathogenesis; however, the triggering factors and the period of their action are unknown. Recent studies in rodents have shown that exposure to lead during brain development predetermined the expression and regulation of the amyloid precursor protein and its amyloidogenic beta-amyloid product in old age. Here, we report that the expression of AD-related genes [APP, BACE1 ] as well as their transcriptional regulator were elevated in aged (...) monkeys exposed to Pb as infants. Furthermore, developmental exposure to Pb altered the levels, characteristics, and intracellular distribution of Abeta staining and amyloid plaques in the frontal association cortex. These latent effects were accompanied by a decrease in DNA methyltransferase activity and higher levels of oxidative damage to DNA, indicating that epigenetic imprinting in early life influenced the expression of AD-related genes and promoted DNA damage and pathogenesis. These data suggest that AD pathogenesis is influenced by early life exposures and argue for both an environmental trigger and a developmental origin of AD. (shrink)

The basis of Muslim philosophy and science is the instruction embedded in the Quran. At an early date this tradition was enlarged and strengthened by the infiltration into Muslim culture of Greek philosophy and science through the translation of Greek classics by Muslims. The Indian tradition of thought also made its contribution. This book traces the development and interaction of these strands in Muslim thinking. The author is concerned to show both how philosophy and science are related to specifically religious (...) thought, and how they have made distinctive contributions to method and discovery.

If we consult the Anthologia Lyrica of E. Diehl and the Geschichte der griechischen Literatur of Schmid-Stählin, we find that they consider as genuine the three epigrams on Hermae which the Palatine Anthology attributes to Anacreon. The question of the authenticity of these epigrams has been for long a matter of dispute, but we may shed further light on it if we take into account the spread of the cult of Hermes in Attica and Anacreon's visit, or possibly visits, to (...) Athens. (shrink)

The relationship of the identity of indiscernibles principle to other major metaphysical principles (e.g., relational doctrine of space and time, elimination of singular terms) is discussed, the aim being to outline the necessary requirements of a systematic metaphysics incorporating the former principle. the conclusion is that no adequate systematic metaphysics of this sort is defensible. throughout special attention is paid to modern logical formulation of the principle and to its role in quine's philosophy.

Peter Geach supports his case that the religion of Thomas Hobbes was both genuine and a version of Socinianism principally by comparing the theological and scriptural sections of Leviathan with the main doctrines of Socinianism and its latter-day developments in Unitarianism and Christadelphianism. He pays particular attention to comparisons with the Racovian Catechism, the theological writings of Joseph Priestley and the Christadelphian document Christendom Astray by Robert Roberts.

The thesis of this paper is that scientific method is to be thought of as a complex many-leveled regulatory hierarchy of principles, interacting with theory also viewed as a complex many-leveled hierarchy. This conception of method is illustrated in particular through one episode in the contemporary development of plasma physics, and related to others. It provides for method-theory interaction and for the development of method itself as science develops.

In Cornford's opinion, the theory of Forms as put forward in theParmenides is identical with the theory as stated in the Pbaedo—both of them expressing thethat concrete things are the bearers, simultaneously, of contrary characters. Christopher Kirwan has recently denied this identity, in a paper which, if hisis accepted, will upset many traditions and greatly alter our understandingLthe middle dialogues.

A SLOW revolution in cognitive science is banishing this century's technological conception of mind as disembodied pure thought, namely a material symbol manipulation, and replacing it with next century's conception: mind as the organisation of bodily interaction, intelligent robotics. Here is Clark: Intelligence and understanding are rooted not in the presence and manipulation of explicit, language-like data structures, but in something more earthy: the tuning of basic responses to a real world that enables an embodied organism to sense, act and (...) survive . . . it is now increasingly clear that the alternative to the ``disembodied explicit data manipulation'' vision of AI is not to retreat from hard science; it is to pursue some even harder science. It is to put intelligence where it belongs: in the coupling of organisms and the world that is at the root of daily, fluent action. (p. 4) # AAHPSSS, 1998.
