We must, therefore, make a study of mechanism; but some introduction is advisable, for cybernetics treats the subject from a new, and therefore unusual, ...

2015 Reprint of 1956 Printing. Full facsimile of the original edition. Not reproduced with Optical Recognition Software. Cybernetics is here defined as "the science of control and communication, in the animal and the machine"-in a word, as the art of steersmanship; and this book will interest all who are interested in cybernetics, communication theory and methods for regulation and control. W. Ross Ashby (1903-1972) was an English psychiatrist and a pioneer in cybernetics, the study of complex systems. His two books, (...) "Design for a Brain" and "An Introduction to Cybernetics," were landmark works. They introduced exact and logical thinking into the nascent discipline and were highly influential. Contents include: What is new -- Change -- The Determinate Machine -- The Machine with Input -- Stability -- The Black Box -- Quantity of Variety -- Transmission of Variety -- Incessant Transmission -- Regulation in Biological Systems -- Requisite Variety -- The Error-controlled Regulator -- Regulating the Very Large System -- Amplifying Regulation.

This article analyses domestic and foreign reactions to a 2008 report in the British Medical Journal on the complementary and, as argued, synergistic relationship between palliative care and euthanasia in Belgium. The earliest initiators of palliative care in Belgium in the late 1970s held the view that access to proper palliative care was a precondition for euthanasia to be acceptable and that euthanasia and palliative care could, and should, develop together. Advocates of euthanasia including author Jan Bernheim, independent from but (...) together with British expatriates, were among the founders of what was probably the first palliative care service in Europe outside of the United Kingdom. In what has become known as the Belgian model of integral end-of-life care, euthanasia is an available option, also at the end of a palliative care pathway. This approach became the majority view among the wider Belgian public, palliative care workers, other health professionals, and legislators. The legal regulation of euthanasia in 2002 was preceded and followed by a considerable expansion of palliative care services. It is argued that this synergistic development was made possible by public confidence in the health care system and widespread progressive social attitudes that gave rise to a high level of community support for both palliative care and euthanasia. The Belgian model of so-called integral end-of-life care is continuing to evolve, with constant scrutiny of practice and improvements to procedures. It still exhibits several imperfections, for which some solutions are being developed. This article analyses this model by way of answers to a series of questions posed by Journal of Bioethical Inquiry consulting editor Michael Ashby to the Belgian authors. (shrink)

Though there are good arguments against physician participation in executions, physicians should be allowed to make their own decisions about whether they will participate, and professional medical organizations should not flatly destroy the careers of those who do.

I argue that physicalists have been too conciliatory in granting that certain classic thought experiments about consciousness like Mary the colour scientist, colour spectrum inversion, and zombies provide strong prima facie support for epiphenomenal anti-physicalism. While these thought experiments may suggest that we are intuitive epiphenomenal anti-physicalists when taken individually, when they are appropriately combined, they suggest that epiphenomenal anti-physicalism leads to a version of phenomenal scepticism according to which (i) we cannot know how our states of phenomenal consciousness compare (...) and contrast and (ii) we cannot know how our first-order beliefs about our states of consciousness compare and contrast. Insofar as comparative phenomenal scepticism is a deeply counter-intuitive view, our intuitions about consciousness are far more equivocal than they are widely thought to be. There simply may be no one metaphysical view that should qualify as their obvious champion. (shrink)

Liberals about perceptual contents claim that perceptual experiences can represent kinds and specific, familiar individuals as such; they also claim that the representation of an individual or kind as such by a perceptual experience will be reflected in the phenomenal character of that experience. Conservatives always deny the latter and sometimes also the former claim. I argue that neither liberals nor conservatives have adequately appreciated how the content internalism/externalism debate bears on their views. I show that perceptual content internalism entails (...) conservativism when conjoined with one other, extremely plausible premise. Hence, liberals are committed to perceptual contents externalism, yet they have failed to fully address the consequences that this has for their view. Moreover, the argument is easily adapted to perceptual experiences of Twin Earthable properties, like colour and shape. I use this last result to show why existing conservative arguments that appeal to Twin Earth plausibly overgeneralize. (shrink)

Dr Gillian Craig (1) has argued that palliative medicine services have tended to adopt a policy of sedation without hydration, which under certain circumstances may be medically inappropriate, causative of death and distressing to family and friends. We welcome this opportunity to defend, with an important modification, the approach we proposed without substantive background argument in our original article (2). We maintain that slowing and eventual cessation of oral intake is a normal part of a natural dying process, that artificial (...) hydration and alimentation (AHA) are not justified unless thirst or hunger are present and cannot be relieved by other means, but food and fluids for (natural) oral consumption should never be 'withdrawn'. The intention of this practice is not to alter the timing of an inevitable death, and sedation is not used, as has been alleged, to mask the effects of dehydration or starvation. The artificial provision of hydration and alimentation is now widely accepted as medical treatment. We believe that arguments that it is not have led to confusion as to whether or not non-provision or withdrawal of AHA constitutes a cause of death in law. Arguments that it is such a cause appear to be tenuously based on an extraordinary/ordinary categorisation of treatments by Kelly (3) which has subsequently been interpreted as prescriptive in a way quite inconsistent with the Catholic moral theological tradition from which the distinction is derived. The focus of ethical discourse on decisions at the end of life should be shifted to an analysis of care, needs, proportionality of medical interventions, and processes of communication. (shrink)
