Context The attitudes of medical professionals towards physician assisted dying have been widely discussed. Less explored is the level of agreement among physicians on the possibility of ‘rational suicide’—a considered suicide act made by a sound mind and a precondition of assisted dying legislation. Objective To assess attitudes towards rational suicide in a representative sample of senior doctors in England and Wales. Methods A postal survey was conducted of 1000 consultants and general practitioners randomly selected from a commercially available database. (...) The main outcome of interest was level of agreement with a statement about rational suicide. Results The corrected participation rate was 50%; 363 questionnaires were analysed. Overall 72% of doctors agreed with the possibility of rational suicide, 17% disagreed, and 11% were neutral. Doctors who identified themselves as being more religious were more likely to disagree. Some doctors who disagreed with legalisation of physician assisted suicide nevertheless agreed with the concept of rational suicide. Conclusions Most senior doctors in England and Wales feel that rational suicide is possible. There was no association with specialty. Strong religious belief was associated with disagreement, although levels of agreement were still high in people reporting the strongest religious belief. Most doctors who were opposed to physician assisted suicide believed that rational suicide was possible, suggesting that some medical opposition is best explained by other factors such as concerns of assessment and protection of vulnerable patients.

In face of the multiple controversies surrounding the DSM process in general and the development of DSM-5 in particular, we have organized a discussion around what we consider six essential questions in further work on the DSM. The six questions involve: 1) the nature of a mental disorder; 2) the definition of mental disorder; 3) the issue of whether, in the current state of psychiatric science, DSM-5 should assume a cautious, conservative posture or an assertive, transformative posture; 4) the role (...) of pragmatic considerations in the construction of DSM-5; 5) the issue of utility of the DSM – whether DSM-III and IV have been designed more for clinicians or researchers, and how this conflict should be dealt with in the new manual; and 6) the possibility and advisability, given all the problems with DSM-III and IV, of designing a different diagnostic system. Part 1 of this article took up the first two questions. Part 2 took up the second two questions. Part 3 now deals with Questions 5 & 6. Question 5 confronts the issue of utility, whether the manual design of DSM-III and IV favors clinicians or researchers, and what that means for DSM-5. Our final question, Question 6, takes up a concluding issue, whether the acknowledged problems with the earlier DSMs warrants a significant overhaul of DSM-5 and future manuals. As in Parts 1 & 2 of this article, the general introduction, as well as the introductions and conclusions for the specific questions, are written by James Phillips, and the responses to commentaries are written by Allen Frances.

Todd Moody’s Zombie Earth thought experiment is an attempt to show that ‘conscious inessentialism’ is false or in need of qualification. We defend conscious inessentialism against his criticisms, and argue that zombie thought experiments highlight the need to explain why consciousness evolved and what function(s) it serves. This is the hardest problem in consciousness studies.

Recovering Reason: Essays in Honor of Thomas L. Pangle is a collection of essays composed by students and friends of Thomas L. Pangle to honor his seminal work and outstanding guidance in the study of political philosophy. These essays examine both Socrates' and modern political philosophers' attempts to answer the question of the right life for human beings, as those attempts are introduced and elaborated in the work of thinkers from Homer and Thucydides to Nietzsche and Charles Taylor.

In the conclusion to this multi-part article I first review the discussions carried out around the six essential questions in psychiatric diagnosis – the position taken by Allen Frances on each question, the commentaries on the respective question along with Frances’ responses to the commentaries, and my own view of the multiple discussions. In this review I emphasize that the core question is the first – what is the nature of psychiatric illness – and that in some manner all further (...) questions follow from the first. Following this review I attempt to move the discussion forward, addressing the first question from the perspectives of natural kind analysis and complexity analysis. This reflection leads toward a view of psychiatric disorders – and future nosologies – as far more complex and uncertain than we have imagined. (shrink)

In lieu of an abstract, here is a brief excerpt of the content:76 AN UNNOTICED ERROR IN HUME'S TREATISE "...the conformity between love and hatred in the agreeableness of their sensation makes them always be excited by the same objects..." Treatise, Book II, Part II, Sec. X. This passage from Hume's A Treatise of Human Nature is taken from the first edition of 1739. It can also be found in the Everyman Edition, the editions of Selby-Bigge Mossner, and Green and (...) Grosse, without editorial comment of any kind. Yet it contains a glaring and obvious error. The most superficial reading of Book II will convince one that it is love and pride that conform in the agreeableness of their sensation they are both indirect passions that aire pleasant in feeling. On the other hand, humility and hatred share in being disagree able or unpleasant impressions. This might have been a printer's error, or Hume's own mistake, and the reason for it is not hard to find. This part of Book II was called "Of love and hatred" ; the expression "love and hatred" recurs several times throughout the whole. In ei»ther the writing of the manuscript or the type setting of the text, a habit was established. Habit, which Hume himself used to explain so much else, must here be cited as the explanation of this slip. What is more interesting is the reason why such an obvious error has gone so long unnoticed. Here an ambiguity in Hume's use of the word "object" should be noticed. It is sometimes used simply as a synonym for "thing" and this is the usage in "excited by the same objects". Hume is merely saying that love and pride have the same sorts of cause. When this cause is found in oneself it leads to pride and when in another it leads to love. This of course is connected with the fact that both these passions are aggreeable or pleasant in sensation. 77 "Object" also has a special technical use in Book II when it refers to the person towards whom the passion is directed, as in "the object of the passion". Now love and hatred do have a similar sort of object, i.e. another person, whereas the object of pride and humility is, according to Hume, always oneself. In this usage, the object of a passion is carefully distinguished by Hume from its cause. It is possible that a careless and superficial reading of this passage might lead one to think that Hume meant to say that love and hatred agree in having the same sort of object, i.e. another person. Such inattention is to be deplored, but after all, until very recently, such inattention was typical of the attitude of philosophers towards Book II 2 as a whole. D. W. D. Owen University of Stirling 1.See for instance the previous paragraph; "I have suppos'd all along, that the passions of love and pride, and those of humility and hatred are similar in their sensations, and that the two former are always agreeable, and the two latter painful." 2.Thanks are due to Mr. Roland Hall for checking the first edition on my behalf....

Single-sided deafness (SSD) or profound unilateral hearing loss obligates the only serviceable ear to capture all acoustic information. This loss of binaural function taxes cognitive resources for accurate listening performance, especially under adverse environments or challenging tasks. We hypothesized that adults with SSD would manifest both functional and structural brain plasticity compared to controls with normal binaural hearing. We evaluated functional alterations using magnetoencephalographic imaging (MEGI) of brain activation during performance of a moderately difficult auditory syllable sequence reproduction task and (...) assessed structural integrity using diffusion tensor magnetic resonance imaging (DTI). MEGI showed the SSD cohort to have increased induced oscillations in the theta band over the left superior temporal cortex and decreased induced gamma band oscillations over the frontal and parietal cortices between 175-475 ms following stimulus onset. DTI showed the SSD cohort to have extensive fractional anisotropy reduction in both auditory and non-auditory tracts and regions. Overlaying functional and structural changes revealed by the two imaging techniques demonstrated close registration of cortical areas and white matter tracts that expressed brain plasticity. Hence, complete loss of input from one ear in adulthood triggers both functional and structural alterations to dorsal temporal and frontal-parietal areas. (shrink)

In face of the multiple controversies surrounding the DSM process in general and the development of DSM-5 in particular, we have organized a discussion around what we consider six essential questions in further work on the DSM. The six questions involve: 1) the nature of a mental disorder; 2) the definition of mental disorder; 3) the issue of whether, in the current state of psychiatric science, DSM-5 should assume a cautious, conservative posture or an assertive, transformative posture; 4) the role (...) of pragmatic considerations in the construction of DSM-5; 5) the issue of utility of the DSM - whether DSM-III and IV have been designed more for clinicians or researchers, and how this conflict should be dealt with in the new manual; and 6) the possibility and advisability, given all the problems with DSM-III and IV, of designing a different diagnostic system. Part I of this article will take up the first two questions. With the first question, invited commentators express a range of opinion regarding the nature of psychiatric disorders, loosely divided into a realist position that the diagnostic categories represent real diseases that we can accurately name and know with our perceptual abilities, a middle, nominalist position that psychiatric disorders do exist in the real world but that our diagnostic categories are constructs that may or may not accurately represent the disorders out there, and finally a purely constructivist position that the diagnostic categories are simply constructs with no evidence of psychiatric disorders in the real world. The second question again offers a range of opinion as to how we should define a mental or psychiatric disorder, including the possibility that we should not try to formulate a definition. The general introduction, as well as the introductions and conclusions for the specific questions, are written by James Phillips, and the responses to commentaries are written by Allen Frances.

Part I of this article took up the first two questions. Part II will take up the second two questions. Question 3 deals with the question as to whether DSM-V should assume a conservative or assertive posture in making changes from DSM-IV. That question in turn breaks down into discussion of diagnoses that depend on, and aim toward, empirical, scientific validation, and diagnoses that are more value-laden and less amenable to scientific validation. Question 4 takes up the role of pragmatic consideration in a psychiatric nosology, whether the purely empirical considerations need to be tempered by considerations of practical consequence. As in Part 1 of this article, the general introduction, as well as the introductions and conclusions for the specific questions, are written by James Phillips, and the responses to commentaries are written by Allen Frances.

The 1990’s, we’ve been told, were the decade of the brain. But without anyone announcing or declaring, much less deciding that it should be so, the 90’s were also a breakthrough decade for the study of consciousness. (Of course we think the two are related, but that is another matter altogether.) William G. Lycan leads the charge with his 1987 book Consciousness (MIT Press), and he has weighed-in again with Consciousness and Experience (1996, MIT Press). Together these two books put (...) forth Lycan’s formidable view of consciousness, extending the theory of mind that he calls ‘homuncular functionalism.’ Roughly, Lycan’s view is that conscious beings are hierarchically composed intentional systems, whose representational powers are to be understood in terms of their biological function. In this review we will call the view ‘teleological functionalism’ or ‘teleofunctionalism’ – the homuncular part, for which Lycan and Daniel Dennett argued convincingly, is now so widely accepted that it fails to distinguish Lycan’s view from other versions of functionalism. This, by itself, is a testament to the importance of Lycan’s work. (shrink)

ABSTRACTIn this paper, I consider Adorno's claim that art is at, or is coming to, an ‘end’. I consider Adorno's account in relation to the work of Arthur Danto and G. W. F. Hegel. I employ Danto's account, together with two distinct interpretive glosses of Hegel's account, as heuristic devices in order to clarify both Adorno's own arguments, and the context within which they are being advanced. I argue that while Danto and Hegel see art as coming to an end (...) autonomously, owing to art's successful realization of its governing principle, Adorno by contrast sees art as coming to an end heteronomously. Art's narrative is forcibly broken off, rather than completed. Adorno's account, indebted to Hegel, of art's commitment both to autonomy and the realization of ‘spiritual needs’ is explored in order to clarify how, on Adorno's view, this has happened to art; and why, precisely, he believes art is coming to an end.

A classic result in the foundations of Yang-Mills theory, due to J. W. Barrett ["Holonomy and Path Structures in General Relativity and Yang-Mills Theory." Int. J. Th. Phys. 30, ], establishes that given a "generalized" holonomy map from the space of piece-wise smooth, closed curves based at some point of a manifold to a Lie group, there exists a principal bundle with that group as structure group and a principal connection on that bundle such that the holonomy map corresponds to (...) the holonomies of that connection. Barrett also provided one sense in which this "recovery theorem" yields a unique bundle, up to isomorphism. Here we show that something stronger is true: with an appropriate definition of isomorphism between generalized holonomy maps, there is an equivalence of categories between the category whose objects are generalized holonomy maps on a smooth, connected manifold and whose arrows are holonomy isomorphisms, and the category whose objects are principal connections on principal bundles over a smooth, connected manifold. This result clarifies, and somewhat improves upon, the sense of "unique recovery" in Barrett's theorems; it also makes precise a sense in which there is no loss of structure involved in moving from a principal bundle formulation of Yang-Mills theory to a holonomy, or "loop", formulation.

Kant and Education brings together sixteen essays by an international group of scholars. The range of topics covered in the anthology is impressive. Kant's contribution to contemporary theories of education is central, as well as Kant's intellectual debt to Rousseau, the role of education in Kant's normative theories, and the impact of Kant's ideas on subsequent generations. Add to this the relative shortness of each essay (ten to fifteen pages), and one is left with an accessible introduction to a fascinating, (...) but often neglected, topic of Kant's ethical theory. The editors, Klas Roth and Chris W. Surprenant, have done an admirable job. (shrink)

This is the first book to offer the best essays, articles, and speeches on ethics and intelligence that demonstrate the complex moral dilemmas in intelligence collection, analysis, and operations. Some are recently declassified and never before published, and all are written by authors whose backgrounds are as varied as their insights, including Robert M. Gates, former Director of the Central Intelligence Agency; John P. Langan, the Joseph Cardinal Bernardin Professor of Catholic Social Thought at the Kennedy Institute of Ethics, Georgetown (...) University; and Loch K. Johnson, Regents Professor of Political Science at the University of Georgia and recipient of the Owens Award for contributions to the understanding of U.S. intelligence activities. Creating the foundation for the study of ethics and intelligence by filling in the gap between warfare and philosophy, this is a valuable collection of literature for building an ethical code that is not dependent on any specific agency, department, or country.

During the decades following the publication of Darwin's Origin of species in 1859, religious belief in England and in particular the Church of England experienced some of the most intense criticism in its history. The early 1860s saw the appearance of Lyell's Evidence of the antiquity of man , Tylor's research on the early history of mankind , Renan's Vie de Jésus , Pius IX's encyclical, Quanta cura, and the accompanying Syllabus errarum, John Henry Newman's Apologia , and Swinburne's notorious (...) Atalanta in Calydon ; it was in this period also that Arthur Stanley was appointed Dean of Westminster, and that Bills were introduced in Parliament to amend or repeal the ‘Test Acts’ as they affected universities. They were the years that witnessed Lyell present the case for geology at the British Association at Bath , the first meeting of the X-Club , and the award of the Royal Society's Copley Medal to Charles Darwin. These were the years in which, as Owen Chadwick has put it, ‘the controversy between “science” and “religion” took fire’. (shrink)

There have in recent years been at least two important attempts to get to grips with Aristotle's conception of dialectic. I have in mind those by Martha C. Nussbaum in ‘Saving Aristotle's appearances’, which is chapter 8 of her The Fragility of Goodness, and by Terence H. Irwin in his important, though in my opinion somewhat misguided, book Aristotle's First Principles. There is a sense in which both of these writers are reacting to the work of G. E. L. Owen (...) on cognate matters, particularly his well-known paper ‘Tithenai ta phainomena’. Owen himself was in part reacting to what I suppose is the traditional view of how Aristotle regarded dialectic, as revealed in Topics I. 1. On that view dialectic is for Aristotle a lesser way of proceeding than is demonstration, the method of science. For demonstration proceeds from premises which are accepted as true in themselves and moves from them to conclusions which follow necessarily from those premises; and the middle term of such a demonstrative syllogism then provides the ‘reason why’ for the truth of the conclusion. Dialectic proceeds from premises which are accepted on a lesser basis ‘by everyone or by the majority or by the wise, i.e. by all, or by the majority, or by the most notable and reputable of them’, and proceeds deductively from them to further conclusions.

We report on an interview-based study of decision-making capacity in two classes of patients suffering from depression. Developing a method of second-person hermeneutic phenomenology, we articulate the distinctive combination of temporal agility and temporal inability characteristic of the experience of severely depressed patients. We argue that a cluster of decision-specific temporal abilities is a critical element of decision-making capacity, and we show that loss of these abilities is a risk factor distinguishing severely depressed patients from mildly/moderately depressed patients. We explore (...) the legal and clinical consequences of this result. (shrink)

There are many reasons to rejoice at this revision of Owens' masterful work, although one might question the term "revision." There are no substantive revisions in the text. There is a very important addition, the Foreword to the Second Edition, in which Owens defends his views against critics and goes on to point out some conclusions about the nature of the Metaphysics which were not explicitly stated in the previous edition, notably that Aristotle's metaphysics was necessarily not a system and (...) was necessarily incomplete. New bibliographical information has been included in footnotes throughout and the Bibliography has been up-dated. The major improvement in the book is that it has now been printed with regular set type. An almost equal boon to the reader is the inclusion of the footnotes at the bottom of the appropriate pages, rather than as a separate section at the back of the book. That extensive revisions of a substantive nature were not necessary is only one more tribute to the excellence of Owens' original work.--W. G. E. (shrink)

With the waves of reform occurring in mental health legislation in England and other jurisdictions, mental capacity is set to become a key medico-legal concept. The concept is central to the law of informed consent and is closely aligned to the philosophical concept of autonomy. It is also closely related to mental disorder. This paper explores the interdisciplinary terrain where mental capacity is located. Our aim is to identify core dilemmas and to suggest pathways for future interdisciplinary research. The terrain (...) can be separated into three types of discussion: philosophical, legal and psychiatric. Each discussion approaches mental capacity and judgmental autonomy from a different perspective yet each discussion struggles over two key dilemmas: whether mental capacity and autonomy is/should be a moral or a psychological notion and whether rationality is the key constitutive factor. We suggest that further theoretical work will have to be interdisciplinary and that this work offers an opportunity for the law to enrich its interpretation of mental capacity, for psychiatry to clarify the normative elements latent in its concepts and for philosophy to advance understanding of autonomy through the study of decisional dysfunction. The new pressures on medical and legal practice to be more explicit about mental capacity make this work a priority. (shrink)

This volume is a collection of papers from the Third Consultation on Hermeneutics at Drew University. The goal of this conference was, in Hopper's words, to "question what kind of language, or thinking, is appropriate to a fundamental ontology, to a language that does not commit objectification, or reification, upon its subject matter in the very mode of its utterance." The first essay in the volume was not read at the conference, but is reprinted from a 1961 Harper's magazine, namely, (...) Norman O. Brown's "Apocalypse: the Place of Mystery in the Life of the Mind." It is unfortunate that Brown is given the place of honor in this collection, since his essay is somewhat offensive and irresponsible. Consider, for example: "Truth is what any fool can see. This is what is meant by so-called scientific method. So-called science is that attempt to democratize knowledge—the attempt to substitute method for insight, mediocrity for genius, by getting a standard operating procedure," or "Vacancy is not the worst condition of mind." Of the remaining papers in this book, the high-points are Kenneth Burke's "Theory of Terminology," a reader's key to his many fine writings on figurative language, Beda Allemann's "Metaphor and Antimetaphor," an interesting analysis of Kafka's prose style, and Owen Barfield's "Imagination and Inspiration," an essay on the difficulties of talking about spiritual experiences in understandable language. In fact, Barfield levels the most relevant criticism at this symposium when he cautions that "very different considerations apply to the exercise of the imagination on the one hand, and, on the other, any attempt to investigate its nature."—E.

At their first meeting Polynices and Tydeus come to blows. They are reconciled by Adrastus, who expresses the hope that their quarrel will lead to loyal friendship between them, as it did. Esse pro fuisse dixit, says Lactantius, more ingenuously than Klotz, who tries to make the same thing more palatable by saying esse est pro imperfecti quodammodo infinitiuo. Some have taken the accusative and infinitive to be a general statement, but Heuvel is clearly right in saying that it is (...) Tydeus and Polynices whom the poet has in mind. The most favoured solution has been Grater's conjecture isse, but that produces an unnatural expression ; Mozley renders it by ‘grew’, thereby translating not what stands in his text but what ought perhaps to stand there, namely esse, a conjecture of Gil, which has been almost entirely overlooked. This contracted form is found in extant literature only at Lucretius 3.683 and Ovid, Met. 7.416 . The first letters of a line are particularly liable to omission; despite Hill, I do not find it at all surprising that at 1.544 perseus lost its first letter and the remnant became aureus. (shrink)

Before daybreak on 23 November 57 B.C., about 11 weeks after his return from exile, Cicero wrote to Atticus and recorded for him, in diary form, events at Rome between 3 November and the date of writing. Clodius and his gangs were still causing trouble on the streets, interfering with the rebuilding of Cicero's house on the Palatine, and even molesting Cicero himself. Clodius was a candidate for the curule aedileship; if he were elected, he would succeed in evading the (...) accusation for vis which had been brought against him by Milo; he therefore made full use of his gangs to intimidate Rome and thus accelerate the elections. He was supported in this manœuvre by the consul Q.

Seneca is dealing with rainbows. Hine shares (...) Axelson's suspicion of ictus, but is unhappy both with Axelson's situs and with my tractus, ‘direction’ ; very tentatively he suggests angulus. Much more credible palaeographically and still yielding good sense and a good clausula would be i etus, a noun which is very common in this work of Seneca's.
