There is no subject at the interface of law, psychiatry and medical ethics which is more controversial than psychosurgery. The divergent views of the treatment begin with its definition. The World Health Organisation1 and others2 define psychosurgery as the selective surgical removal or destruction of nerve pathways or normal brain tissue with a view to influencing behaviour. However, proponents of psychosurgery demur on the basis that the `modern' treatment is concerned predominantly with emotional illness, without any specific effect upon behaviour. (...) The alternative definition offered is `the surgical treatment of certain psychiatric illnesses by means of localised lesions placed in specific cerebral sites.3It is difficult entirely to accept this definition because, as examined below, scientific psychiatry is not yet in a position to directly treat psychiatric illness solely through surgical intervention. There is no reliable theoretical relationship between particular cerebral sites (which are normal and healthy) and an identifiable psychiatric illness or symptomatology. Given this state of psychiatric understanding, it is misleading to suggest fine distinctions between generalised alteration of behaviour or mood and treatment of an illness. Highly divergent practices and theories (relating to the multiplicity of conditions treated, surgical methods adopted and areas of the brain operated upon) further undermine exaggerated claims that psychosurgery can scientifically `treat' specific illness through precise surgical intervention. Nonetheless, contemporary psychosurgery does not contain quite the same `broadbrush' approach of its ancestors and it can lay some legitimate claim as an effective empirical treatment in narrowly limited circumstances. Major ethical problems still, however, arise and these will be discussed in this article. (shrink)

[opening paragraph] -- Clark: The `astonishing hypothesis' which you put forward in your book, and which you obviously feel is very controversial, is that `You, your joys and sorrows, your memories and ambitions, your sense of personal identity and free will are, in fact, no more than the behaviour of a vast assembly of nerve cells. As Lewis Carroll's Alice might have phrased it: `You're nothing but a pack of neurons'.' But it seems to me that this is not so (...) astonishing a statement for a scientist to make. Isn't this what reductionist science has always believed? (shrink)

ics. Each of these can be pursued independently to a large extent, but perhaps most intriguing is to contem- plate how progress in each will affect the other.

'Most of us are still groping for answers about what makes life worth living, or what confers meaning on individual lives', writes Charles Taylor in Sources of the Self. 'This is an essentially modern predicament.' Charles Taylor's latest book sets out to define the modern identity by tracing its genesis, analysing the writings of such thinkers as Augustine, Descartes, Montaigne, Luther, and many others. This then serves as a starting point for a renewed understanding of modernity. Taylor argues that modern (...) subjectivity has its roots in ideas of human good, and is in fact the result of our long efforts to define and attain the good. The modern turn inwards is far from being a disastrous rejection of rationality, as its critics contend, but has at its heart what Taylor calls the affirmation of ordinary life. He concludes that the modern identity, and its attendant rejection of an objective order of reason, is far richer in moral sources that its detractors allow. Sources of the Self provides a decisive defence of the modern order and a sharp rebuff to its critics. (shrink)

Exploring the origins, doctrines and conceptions of the self.

Representations of the active brain have served to establish a particular domain of competence for brain mappers and to distinguish brain mapping’s particular contributions to mind/brain research. At the heart of the claims about the emerging contributions of functional brain mapping is a paradox: functional imagers seem to reject representations while also using them at multiple points in their work. This article therefore considers a love-hate relationship between scientists and their object: the case of the iconoclastic imager. This paradoxical stance (...) is the result of the formation of an interdisciplinary approach that brings together a number of scientific traditions and their particular standards of what constitutes scientific evidence. By examining the various ways in which images are deployed and rejected, the origins of these conflicting tendencies can be traced to the technological, methodological, and institutional elements in the work of functional imagers. This approach provides insight into the current demarcation of imaging and reflects on features of visual knowledge. (shrink)

One of the greatest thinkers of the nineteenth century, Søren Kierkegaard often expressed himself through pseudonyms and disguises. Taken from his personal writings, these private reflections reveal the development of his own thought and personality, from his time as a young student to the deep later internal conflict that formed the basis for his masterpiece of duality Either/Or and beyond. Expressing his beliefs with a freedom not seen in works he published during his lifetime, Kierkegaard here rejects for the first (...) time his father's conventional Christianity and forges the revolutionary idea of the "leap of faith" required for true religious belief. A combination of theoretical argument, vivid natural description and sharply honed wit, the Papers and Journals reveal to the full the passionate integrity of his lifelong efforts "to find a truth which is truth for me."
