Idiopathic Parkinson’s disease impairs working memory, but the exact nature of this deficit in terms of the underlying cognitive mechanisms is not well understood. In this study patients with mild clinical symptoms of PD were compared with matched healthy control subjects on a computerized battery of tests designed to assess spatial working memory and verbal working memory. In the spatial working memory task, subjects were required to recall a sequence of four locations. The verbal working memory task was methodologically identical (...) except for the modality of the stimuli used, requiring subjects to orally recall a sequence of six digits. In either case, half of the sequences were structured in a way that allowed ‘chunking’, while others were unstructured. This manipulation was designed to dissociate the strategic component of task performance from the memory-load component. Mild medicated patients with PD were impaired only on the structured versions of the verbal working memory tasks. The analogous deficit in the spatial working memory was less pronounced. These findings are in agreement with the hypothesis that working memory deficits in PD reflect mainly the executive component of the tasks and that the deficits may be at least partly modality-independent.

Rogers suggests that human spirituality comprises the interplay of three foundational human dynamics: suffering, interconnecting, and valuing. The spiritual orientations that result from these clusters of dynamics are primarily integrating or disintegrating. The dominant spiritual orientation in this country has been disintegrating; and this orientation has characterized the attitude of the majority population toward African Americans since the beginning of slavery, fostering radical separation, displacing the suffering of the majority onto a minority, and defining the experience and perspectives of (...) the majority as normative without regard for the minority. Rogers explores the effects of this disintegrating spiritual orientation in terms of the dynamics of oppression using the ideas of 'being' and 'non-being'. The key to ameliorating oppression is to recognize the liberating capacity of suffering as potentially subversive within ever-enlarging contexts addicted to increasing material consumption and sensual gratification. ;Chapter 1 is a general introduction to the dissertation. ;Chapter 2 provides an overview of the primary methodology for research in 'formation theory' as developed by Adrian van Kaam. Using issues from the philosophy of science, the chapter also discusses the basis for divergence from the standard methodology based in the anomalous character of the researcher's 'formative event' and perspective relative to concerns that have been researched using formation theory. ;Chapter 3 considers a conceptualization of spirit as questing for meaningfulness, which provides the experiential ground for relating spirituality and liberation: Since oppression precipitates meaninglessness through disintegration, the reaffirmation of an integrative spirituality provides the ground for meaningfulness, which in turn grounds liberation, or transcendence. ;Chapter 4 presents the construct of human spirituality using the three foundational foci of spiritual formation: suffering, relating, and valuing. ;Chapter 5 concludes the dissertation using the two principle laws of thermodynamics to develop an analogous understanding for the necessity of suffering in maintaining an integrative and liberating spirituality. It also considers implications of the dissertation for liberation of oppressed peoples, the development of science and social policy, and formation theory. (shrink)

Committee: Maria Bittner (chairperson), Hans Kamp (external member), Roger Schwarzschild and Matthew Stone.

Dr Adrian Rogers delivers a three-pronged assault on the concepts of 'situational ethics'; the eleemosynary principles underlying the National Health Service, and the permissiveness of modern society. I hold strong, and largely opposite, views on each of these matters, which are outlined in this paper.

Anthony Rudd presents a striking new account of the self as an ethical, evaluative being.

This book is a discussion of some of Kierkegaard's central ideas, showing their relevance to contemporary debates in epistemology, ethics, and the philosophy of religion. Anthony Rudd's aim is not simply to expound Kierkegaard's ideas but to draw on them creatively in order to illuminate questions about the foundations of morality and the nature of personal identity, as discussed by analytical philosophers such as MacIntyre, Parfit, Williams, and Foot. Rudd seeks a way forward from the sterile conflict between (...) the view that morality and religion are based on objective reasoning and the view that they are merely expressions of subjective emotions. He argues that morality and religion must be understood in terms of the individual's search for a sense of meaning in his or her own life, but emphasizes that this does not imply that values are arbitrary or merely subjective.

This thoughtful book argues that skepticism -- the view that reliable knowledge is beyond our grasp -- is unavoidable unless knowledge is thought of not as merely an intellectual matter but as crucial to practical activity and emotional life. Author Anthony Rudd ties this idea to the work of Wittgenstein and Heidegger, exploring important similarities between the former's reminders of the "expressive" character of human experience and the latter's account of ways to experience the physical world "expressively.".

Over the last few decades, a number of influential philosophers, psychologists and others have invoked the notion of narrative as having a central role to play in our thinking about ethics and personal identity. More recently, a backlash against these narrative theories has developed, exemplified in work by, for instance, Galen Strawson, Peter Lamarque and John Christman. This paper defends an approach to personal identity and ethics, influenced mainly by Alasdair MacIntyre and Charles Taylor, in which narrative plays a central (...) (though not a foundational) role. In sec I, I elucidate the concept of narrative that MacIntyre introduced in After Virtue and show why this is central to thinking about the identity of persons across time. In sec II, I consider and reject various objections to this narrative account of personal identity. I hope to show that some of the prominent criticisms of narrative theory simply don’t apply to this conception, properly understood. However, I don’t want to claim that the dispute over narrative is based purely on misunderstanding, One centrally important aspect of the dispute is a first-order ethical one about the extent to which we should seek for a unity based on narrative coherence in our lives, and in secs III and IV, I will offer a defence of Taylor’s claim that an ethical life must aspire to, and to some extent achieve, narrative unity.

In a recent article in this journal, John Lippitt mounts a forceful argument against narrativist approaches to issues in personal identity and practical deliberation, with specific reference to the application of such approaches in the interpretation of Kierkegaard's writings. The present critical discussion piece addresses two points in Lippitt's argument. First, it seeks to meet Lippitt's challenge to clarify the notion of "a whole life" as this figures in narrativist positions. Second, it clarifies the sense in which narrative unity, and (...) even selfhood, may be a matter of degree. It then uses this latter insight to sketch a defense of the claim that narrativity may indeed play a crucial role in Kierkegaard's distinction between ethical and aesthetic ways of life. (shrink)

This paper starts from the debate between proponents of a neo-Lockean psychological continuity view of personal identity, and defenders of the idea that we are simple mental substances. Each party has valid criticisms of the other; the impasse in the debate is traced to the Lockean assumption that substance is only externally related to its attributes. This suggests the possibility that we could develop a better account of mental substance if we thought of it as having an internal relation to (...) its states. I suggest that we may be able to do this by relying on the notion of expression. In developing this idea I draw heavily on aspects of Wittgenstein's philosophical psychology, while also developing and criticizing Strawson's account of persons and recent work by Lynne Baker. I conclude by arguing that mental substance, understood in this way, can only be grasped in narrative terms; substantialist and narrative accounts of personal identity, far from being opposed, are mutually supporting and require one another to be coherent.

It is often argued that the existence of qualia -- private mental objects -- shows that physicalism is false. In this paper, I argue that to think in terms of qualia is a misleading way to develop what is in itself a valid intuition about the inability of physicalism to do justice to our conscious experience. I consider arguments by Dennett and Wittgenstein which indicate what is wrong with the notion of qualia, but which by so doing, help us to (...) locate the real problem for physicalism. This is not that there may be mental as well as physical objects of which we are aware, but that the very notion of awareness is itself resistant to physicalist treatment. In the concluding sections, I draw on Wittgenstein's positive account of sensations, to suggest a way in which the apparent chasm separating objective and subjective viewpoints might be bridged in a non-reductive fashion.

This paper examines Kierkegaard 's discussion of patience in some of his Upbuilding Discourses, and its connection with his understanding of the nature of selfhood as it appears both in the Discourses and in The Sickness unto Death. That understanding stresses that selfhood is not simply given, but is a task to be achieved—although a task that can only be achieved by the self that is formed in the process of undertaking it. For Kierkegaard, an account of the self that (...) recognizes its essential temporality must give a crucial role to patience as a virtue necessary for the formation and maintenance of personal identity. However, although the self is essentially temporal for Kierkegaard, it is also essentially such as to participate in eternity, and this complexity and tension in his concept of the self gives his understanding of patience a particular character—one that presents an important challenge to some of the dominant assumptions of recent and contemporary philosophy in both the analytic and the continental traditions.

Internationally, governments, health and exercise practitioners are struggling with the threat posed by physical inactivity leading to worsening outcomes in health and life expectancy and the associated high economic costs. To meet this challenge it is important to enhance the quality, and quantity, of participation in sports and physical activity throughout the life course to sustain healthy and active lifestyles. This paper supports the need to develop a physically literate population, who meaningfully engage in play and physical activity through the (...) development of functional movement skills in enriched environments. This is a shift away from reductionist approaches to physical activity engagement and maintenance to an ecological dynamics approach that focuses on enrichment to support functional movement skill learning and development. This is an embedded approach to physical literacy that allows learners the space and time to “explore–discover” within environments that will lead to a concomitant self-organization of highly intricate network of co-dependent sub-systems resulting in functional movement solutions for the performance task and enduring positive adaptations to subsystems supporting the physical literacy journey across the life course. “Explore-discover adapt” is at the heart of two contemporary learner-centered pedagogies: Non-linear Pedagogy and the Athletic Skills Model. Both emphasize the importance of enrichment experiences from an early age, and throughout life course, and both appreciate the inherent complexity involved in the learning process and the importance of designing a rich and varied range of athletic, participatory experiences that will support the embedded development of physical literacy leading to ongoing physical activity for all. The final part of this paper will demonstrate the potential of an ecological dynamics approach for supporting the concept of physical literacy by providing a roadmap for a reliable and valid measurement of physical literacy when considered from both an ecological dynamics perspective and the phenomenology understanding of physical literacy.

This paper defends and develops an argument against epiphenomenalism, broadly construed. I argue first for a definition of epiphenomenalism which includes ‘non-reductive’ materialism as well as classical dualistic epiphenomenalism. I then present an argument that if epiphenomenalism were true it would be impossible to know about or even refer to our conscious states -- and therefore impossible even to formulate epiphenomenalism. David Chalmers has defended epiphenomenalism against such arguments; I consider this defence and attempt to show that it fails. I (...) conclude that an adequate account of mental causation requires us to abandon the principle of the causal closure of the physical, and attempt to rebut charges that it would be ‘unscientific’ to do so.

It is widely thought that sceptical arguments, if correct, would show that everyday empirical knowledge‐claims are false. Against this, I argue that the very generality of traditional sceptical arguments means that there is no direct incompatibility between everyday empirical claims and sceptical scenarios. Scepticism calls into doubt, not ordinary empirical beliefs, but philosophical attempts to give a deep ontological explanation of such beliefs. G. E. Moore's attempt to refute scepticism (and idealism) was unsuccessful, because it failed to recognise that philosophical (...) scepticism operates on a different level from that on which we make – or doubt – particular empirical claims. And, as I argue with specific reference to work by Nozick and Fogelin, Moore’s basic confusion is still widely shared in contemporary discussions of scepticism. (shrink)

A contrast is drawn between two types of externalism, one based on ideas of Wittgenstein, the other on arguments from Putnam. Gregory McCulloch’s attempt to combine the two types is then examined and criticized. Putnamian externalism is ambiguous. It can be interpreted either as the empirical claim that we give priority to scientific as opposed to other forms of discourse, or as a metaphysical claim that our language attempts to conform to the structure of the world ‘in itself’. But the (...) first claim is simply false, and the second involves a form of metaphysical realism that a Wittgensteinian must reject as unintelligible. McCulloch’s attempted synthesis of the two types is therefore either incoherent, or else simply adds an empirical falsehood to Wittgenstein’s conceptual point. It is also noted that Putnam himself has progressively retreated from his original claims, and now appears to be a Wittgensteinian, but not a ‘Putnamian’, externalist. (shrink)

I critically discuss two claims which Hannah Ginsborg makes on behalf of her account of meaning in terms of ‘primitive normativity’: first, that it avoids the sceptical regress articulated by Kripke's Wittgenstein; second, that it makes sense of the thought—central to Kripke's Wittgenstein—that ‘meaning is normative’, in a way which shows this thought not only to be immune from recent criticisms but also to undermine reductively naturalistic theories of content. In the course of the discussion, I consider and attempt to (...) shed light on a number of issues: the structure of the sceptical regress; the content of the thought that ‘meaning is normative’, and its force against reductive theories; the connection between meaning and justification; and the notion of ‘primitive normativity’.

The question of the value of painting—why paintings should matter to us—has been addressed by a number of Phenomenological philosophers. In this paper, I critically review recent discussions of this topic by Simon Crowell and Paul Crowther—while also looking back to work by Merleau-Ponty and Michel Henry. All the views I discuss claim that painting is important because it can make manifest certain philosophically important truths. While sympathetic to this approach, I discuss various problems with it. Firstly, are these truths (...) verbally explicable, or only communicable through the artwork itself? Secondly, if its truthfulness is the reason why we value painting, can this criterion track our intuitive judgements about relative artistic merit? Thirdly, can the truthfulness of painting be a reason for valuing it if that truth is divorced from its traditional association with Beauty and Goodness? I suggest ways in which the first and second problems could in principle be solved, but argue in response to the third that truth must indeed be seen in the context of other values if it is to explain why painting matters.

Summary The twofold objective of this study is (1) to identify and give a brief review of the historical development of the various designs of early (pre-1850) telescope eyepieces, and (2) to determine by measurements and calculations the axial and lateral chromatic aberrations of a number of extant eyepieces from that period in order to provide basic data on which to judge the relative quality of different eyepiece forms. Eight distinct types of eyepieces containing one to five lens elements are (...) discussed and illustrated. The second objective was addressed by measuring the focal lengths of the individual lens elements and the lens spacings in each eyepiece. The data were processed by a ray-tracing program that yields the chromatic aberration (CA) and focal length of each of the eyepieces. Twenty-one telescopes from that period were studied in this way. Similar calculations were also made using data available in the literature on several additional historic telescopes. The conclusions drawn from the data are: (1) Telescopes with Galilean eyepieces have a smaller CA than those with Keplerian or Huygens eyepieces. (2) The two-lens Keplerian terrestrial eyepieces are demonstrated to have larger axial and lateral CA than any of the other eyepiece types. (3) Calculations from examples of telescopes by Divini and Campani for which data were available indicate that while the axial CAs of the two were the same, Campani's instrument had a much smaller lateral CA. (4) Five element eyepieces were found to be better corrected for CA than the early four-lens systems that replaced them. (5) This study tends to confirm the speculation that the reason makers of early achromatic telescopes overcorrected the objective lenses was to compensate for the CA of the eyepieces. (shrink)

This paper responds to Dan Hutto’s paper, ‘Narrative Self-Shaping: a Modest Proposal’. Hutto there attacks the “strong” narrativism defended in my recent book, ‘Self, Value and Narrative’ and in recent work by Marya Schechtman. I rebut Hutto’s argument that non-narrative forms of evaluative self-shaping can plausibly be conceived, and defend the notion of implicit narrative against his criticisms. I conclude by briefly indicating some difficulties that arise for the “modest” form of narrativism that Hutto defends.

In this essay I argue that the traditional mind-body problem, which seems intractable in its own terms, could be helpfully reconfigured by drawing on insights from the Phenomenological tradition concerning the “body-subject” or “lived body.” Rather than attempting to explain how consciousness relates to the body as understood by the natural sciences, the Phenomenologists concentrate on elucidating the first-person sense that we have of our own bodies in ordinary, prescientific existence. After surveying the traditional mind-body problem in section 1, I (...) introduce the Phenomenological account of embodied subjectivity in section 2. In the remainder of the essay I discuss two important issues raised by this account. First, in section 3, I consider how we can relate our everyday sense of ourselves as embodied subjects to the scientific understanding of the human body—what we might call the “body-body problem.” I argue that, in any case, the latter understanding cannot coherently be supposed to undermine or debunk the former. Secondly, in section 4, I consider whether the Phenomenological stress on the bodily nature of subjectivity allows any room for the notion of disembodied existence. (shrink)

This chapter examines Soren Kierkegaard's relation with Ludwig Wittgenstein and the Wittgenstein philosophical tradition, explaining that Wittgenstein had read a good deal of Kierkegaard's works, admired them, and even called his predecessor the most profound thinker of the nineteenth century. It also mentions that Wittgenstein made explicit references to Kierkegaard in his notebooks, diaries, and letters. The chapter furthermore discusses the influence of Kierkegaard's The Concept of Anxiety, Philosophical Fragments, and The Sickness Unto Death on the works of Wittgenstein.

Many philosophers now argue that the doubts of the philosophical sceptic are unnatural ones, in that they are not forced on us by considerations that any reasonable person would have to accept as compelling but only arise if one has already accepted certain controversial theoretical commitments. In this article I defend the naturalness of philosophical scepticism against such criticisms. After defining "global ontological scepticism," I examine the work of a number of anti-sceptical philosophers—Michael Huemer, Michael Williams, and John McDowell. Although (...) McDowell does move the debate to a deeper level by interpreting scepticism as a challenge to the very possibility of the mind's apprehending reality by being in a rational rather than a merely causal relation to it, none of them succeeds in showing that global ontological scepticism is, in the relevant sense, unnatural. This is not to say that the sceptic is correct; simply that it has not been shown that we can reasonably dismiss the sceptical questions and thereby evade the need to engage seriously with the sceptical arguments.
