Little is known about distance processing in patients with posterior brain damage. Although many investigators have claimed that distance estimates are normal or abnormal in some of these patients, many of these observations were made informally and the examiners often asked for relative, and not absolute, distance estimates. The present investigation served two purposes. First, we wanted to contrast the use of distance information in peripersonal space for perceptual report as opposed to visuomotor control in our visual form agnosic patient, (...) DF. Second, we wanted to see to what extent her abilities to process distance cues were dependent on binocular vision, in light of Milner et al.'s (1991) observations of preserved stereopsis in DF, and Dijkerman et al.'s (1996) and Marotta et al.'s (1997) observations that her visual guidance of grasping may be particularly dependent on binocular vision of the target. We hypothesized that DF's visuomotor responses would show normal sensitivity to target distance, while her perceptual estimates would not. In the first experiment, we required DF and two age- and sex-matched control subjects to reach out and grasp black cubes placed at varying distances, or to estimate the distance of the cubes from the hand starting position without making a reaching movement. In the second experiment, we required DF and two age-matched control subjects to point as rapidly and accurately as possible to small LED targets which differed in spatial location, under binocular and monocular conditions. The results showed that, relative to the control subjects, DF's grasping movements produced normal peak velocity-distance scaling-when she reached for blocks which varied in depth or pointed to LED targets which were presented at different distances in depth. In contrast, in the cube experiment, her verbal estimates of object distance were poorly scaled, although they improved slightly under the binocular conditions. The results are discussed in terms of current theories of processing streams in extrastriate visual cortex and the distinction between categorical and coordinate spatial processing. (shrink)

Disjunctivism is the focus of a lively debate spanning the philosophy of perception, epistemology, and the philosophy of action. Adrian Haddock and Fiona Macpherson present 17 specially written essays, which examine the different forms of disjunctivism and explore the connections between them.

The paper examines a single, apparently simple argument for the existence of incompatibilities between the virtues as traits of character. This argument appeals not to empirical truths about human psychology or human nature but to the possibility of conflict between the exercise of different virtues in action. There are, for example, situations in which we can exercise the virtue of truthfulness only at the expense of not exercising the virtue of tact, as when we are asked a question to which (...) the straightforward answer will pain our questioner. The person who in these situations would give a straightforward answer possesses the virtue of truthfulness to a higher degree than the person who would respond more evasively, whereas the latter person possesses the virtue of tact to a higher degree than the former. But since the two responses are mutually exclusive, it follows that the degree to which we possess the virtue of truthfulness must, at least in some measure, correlate inversely with the degree to which we possess the virtue of tact. And similarly for many other pairs of virtues. My paper focusses on the two cardinal assumptions of this argument, viz., (i) that sometimes the exercise of one virtue can conflict with the exercise of another, and (ii) that the degree to which a person possesses a virtue correlates directly with the extent of its exercise, and defends both assumptions against a variety of objections which allege that, in different ways, they are insensitive to the complexity of the virtues.

In this paper I want to examine a view of the Darwinian theory of evolution which was put forward fairly recently by A. R. Manser. His approach is of interest not only in itself, but also because it may be expanded to raise some fundamental questions about the nature of the science of biology in general. I shall not consider these further implications here, but shall concentrate on an examination of his thesis in the context in which it is raised. (...) My paper falls into two sections. In the first I shall state Manser's thesis and some of the arguments with which he supports it, and shall try to show how a series of objections raised by A. G. N. Flew and K. Connolly may be answered. In the second I shall offer on my own account a positive argument to provide a possible basis for his point of view, with the aim of indicating why the theory should be of the kind he suggests, and what form the study of evolution must take.

At the risk of proving myself such a caviller, I want to ask a question which I have seldom heard raised, and which I have never seen discussed in anything that I have read about Berkeley. If I am right, it poses a problem for his immaterialism, not only different, but coming from a different direction, from those objections that are commonly levelled against him. If I am wrong, it will show how right Berkeley was to stress the difficulty of (...) using for one purpose our language which has become fashioned for another. At least, I hope that I shall not fail to be the ‘fair and ingenuous reader’for whom he asked. (shrink)

The author has recently shown that a mathematical question regarding the fundamental constituents of hardrons cannot be resolved unless the classical axioms of nonfinite mathematics are revised in such a way as to produce a new theory of particle motion in continuous space-time. Under this new theory, the instantaneous position of a moving object has a magnitude that is increasing as the object's velocity. The purpose of this paper is to show that, quite apart from the question of Cantorian axiomatics, (...) the new theory of motion is more consistent with what physicists really believe than the traditional theory of motion.

In lieu of an abstract, here is a brief excerpt of the content:Humanism, Female Education, and Myth:Erasmus, Vives, and More's To CandidusA. D. CousinsWhen considering pleasure and chance as aspects of human experience, Thomas More sometimes gendered them female; that is to say, at times he represented them by drawing from the mythographies of Venus and of Fortune. But what did he suggest that actual women, as distinct from goddesses, were or should be or might become: what were his notions (...) of being a woman, of femaleness? Further, what did he suggest that women might contribute to the common weal? A useful way to start answering that question is to look at what More seems to have thought about educating women: in particular, women who were entering adult life—entering into what was agreed to be the major female role—by marrying for the first time and therefore newly taking upon themselves the management of a household. In one of his most ambitious Latin poems, as nowhere else, More wrote elaborately, concisely and problematically on the education of women who were in just those circumstances. My discussion attempts a repositioning of that poem, To Candidus: How to Choose A Wife A Poem in Iambic Dimeter Brachycatalectic (Versvs Iambici Dimetri Brachycatalectici ad Candidvm, Qvalis Vxor Deligenda). To make the attempt involves examining More's other Latin poems on women, as would be anticipated; however, I am mainly concerned here with affinities between To Candidus—then, to a lesser extent, some of More's associated Latin poems—and notions about female education that were or were to become part of the already long, and mostly male, debate about the nature of femaleness.1 To be [End Page 213] specific, I am chiefly concerned with affinities between More's poem and writings by Erasmus and by Vives on the education of prospective or of recent brides.Because the primary concern in my discussion is to clarify the relations between More's To Candidus and humanist notions on female education, especially notions put forward by two of More's humanist friends about young brides, I want initially to revisit the early modern debate on educating women, of course an important element of the wider debate about femaleness itself. One medieval and thence early modern idea on female education was that, in addition to what their mothers taught them, most women needed merely to receive religious and ethical instruction from their husbands, who would likewise instruct them in how to govern a household.2 After all, it was often pointed out, the household was women's natural domain: since, therefore, they would not normally engage with the world at large as would men—since, for example, they would not normally be educators, or writers, or politicians—women did not usually need the broad education appropriate to men.3 Assertion to the contrary was variously argued—and differences between or among those contrary assertions did not always depend on whether an author was male or female. In The Book of the City of Ladies (1405), a response to Boccaccio's De Mulieribus Claris and, perhaps unknowingly, also to Plutarch's The Virtues of Women, Christine de Pizan attempted to construct at once a refuge and a resource for [End Page 214] women, whom she recognized as having been misrepresented to themselves no less than to men throughout generations of misogynistic male fictions, ranging from satire to epic, from fable to history.4 Her City, in so far as it is a revisionist history of women, forms a textual space which does indeed offer a refuge as well as a resource, for Christine advocates that women, fulfilling their capabilities as women, aim at "cultivat[ing] virtue" and thereby gaining inclusion in the true, illustrious record of female achievement: membership of a textual community within which they will see themselves reflected and which is at one with the City of God.5 Inseparable from their seeking to do so, she emphasizes, will be their receiving education.6 Despite that emphasis—and despite her emphasizing that women are men's intellectual equals or, not infrequently, superiors—Christine nevertheless defends the concept that the domestic sphere and not the public is in general that "appropriate" to women.7...

The rules of formal logic favor the bootstrap over the fundamentalist interpretation of hadronic constituents.

The claims that Dr. F. H. George makes on behalf of his machines are obscurely stated. Does he claim that a machine has been made and has actually produced a kind of response which is incalculable, given the specification to which it has been built and also the prescribed conditions, what is put in for the particular performance in question? “Incalculable” does not mean that nobody has bothered to calculate, but that somebody has bothered, that the calculations show that the (...) response in question is not among the calculated ones, that it is not chance or mechanical breakdown, but a specific response to something specific among the given conditions. If he could substantiate this claim, then I would reluctantly agree that some machines are cleverer and more thoughtful than I thought possible, and some men sillier and less thoughtful, for they deliberately design machines to do they know not what.

I read Dr Cherniack’s article regarding do not resuscitate orders with interest.1 One of the problems with DNR orders is the patients’ assumption that if there is no DNR order they will survive resuscitative efforts. This of course is far from the truth. In my hospital these orders have been modified to “do not attempt to resuscitate” orders. One cannot be truly autonomous without being informed. Long term survival, as measured only by being alive, following inhouse cardiac arrest, is about (...) 15% over all age groups.2 In sick elderly patients over 70 years of age who survive a cardiac arrest, the subsequent hospital mortality approaches 100%.
