This article investigated the paradox between church response to apartheid and resulting action at the local level in the South African churches of European origin from the perspective of the Presbyterian Church of South(ern) Africa (PCSA). It indicated that this discrepancy arose between the reflections (cerebral faith) at the highest levels of church councils, which operated in an intermittent manner and at a distance, compared with the responses (praxis as faith in action) of local church members who lived at (...) the coalface of the struggle and sought to witness in a society dominated by racism, where the tension between faith and politics was most evident. The primary focus was on two inter-racial congregations, one of the PCSA, the other a united congregation in which the PCSA participated. This study used primary and secondary sources. The theoretical framework of the article was Thomas Groome’s approach of shared praxis.Contribution: This article contributed to the history of the apartheid era in ecclesiastical contexts. It demonstrated the anomalies that arose within different constituencies within churches of European origin by investigating the situation in one particular denomination. This was a discussion of the relationship of faith and politics in the private and public domains, which takes account of developments within a shared praxis approach. (shrink)

In the late 19th century, physiologists such as David Ferrier, Eduard Hitzig, and Hermann Munk argued that cerebral brain functions are localized in discrete structures. By the early 20th century, this became the dominant position. However, another prominent physiologist, Friedrich Goltz, rejected theories of cerebral localization and argued against these physiologists until his death in 1902. I argue in this paper that previous historical accounts have failed to comprehend why Goltz rejected cerebral localization. I show that Goltz (...) adhered to a falsificationist methodology, and I reconstruct how he designed his experiments and weighted different kinds of evidence. I then draw on the exploratory experimentation literature from recent philosophy of science to trace one root of the debate to differences in how the German localizers designed their experiments and reasoned about evidence. While Goltz designed his experiments to test hypotheses about the functions of predetermined cerebral structures, the localizers explored new functions and structures in the process of constructing new theories. I argue that the localizers relied on untested background conjectures to justify their inferences about functional organization. These background conjectures collapsed a distinction between phenomena they produced direct evidence for (localized symptoms) and what they reached conclusions about (localized functions). (shrink)

Individuals with cerebral palsy (CP) have deficits in processing of somatosensory and proprioceptive information. To compensate for these deficits, they tend to rely on vision over proprioception in single plane upper and lower limb movements and in standing. It is not known whether this also applies to walking, an activity where the threat to balance is higher. Through this study, we used visual perturbations to understand how individuals with and without CP integrate visual input for walking balance control. Additionally, (...) we probed the balance mechanisms driving the responses to the visual perturbations. More specifically, we investigated differences in the use of ankle roll response i.e., the use of ankle inversion, and the foot placement response, i.e., stepping in the direction of perceived fall. Thirty-four participants (17 CP, 17 age-and sex-matched typically developing controls or TD) were recruited. Participants walked on a self-paced treadmill in a virtual reality environment. Intermittently, the virtual scene was rotated in the frontal plane to induce the sensation of a sideways fall. Our results showed that compared to their TD peers, the overall body sway in response to the visual perturbations was magnified and delayed in CP group, implying that they were more affected by changes in visual cues and relied more so on visual information for walking balance control. Also, the CP group showed a lack of ankle response, through a significantly reduced ankle inversion on the affected side compared to the TD group. The CP group showed a higher foot placement response compared to the TD group immediately following the visual perturbations. Thus, individuals with CP showed a dominant proximal foot placement strategy and diminished ankle roll response, suggestive of a reliance on proximal over distal control of walking balance in individuals with CP.

To assess the ability of the disconnected cerebral hemispheres to recognize images of the self, a split-brain patient was tested using morphed self-face images presented to one visual hemifield at a time while making “self/other” judgments. The performance of the right and left hemispheres of this patient as assessed by a signal detection method was not significantly different, though a measure of bias did reveal hemispheric differences. The right and left hemispheres of this patient independently and equally possessed the (...) ability to self-recognize, but only the right hemisphere could successfully recognize familiar others. This supports a modular concept of self-recognition and other-recognition, separately present in each cerebral hemisphere. (shrink)

I dispute that consciousness is generated by core circuitry in the forebrain, with predominance of motor areas, as Cotterillproposes in Enchanted Looms and other theorists do also. Ipropose instead that conscious contents are the momentary modeof action of the integrated cortical field, expressed as a point vector ( dominant focus ), to which, in varying degree, allsectors of the network contribute. Consciousness is the brain''saccess to its own activity space, and is identical with the moment''sdominant mode of activity. The dominant (...) focus is generally weightedtoward enactively encoded percepts. Anticipation and preparation,perception and action, inextricably interdigitate. I also dispute the view of Cotterill and others that consciousnesshas unique agency, which bestowed adaptive advantage when the brain evolved. Being identical with the activity of the network,consciousness can have no additional agency, and it can offerno adaptive advantages beyond those that characterize the network. (shrink)

ObjectiveThe correlation between the performance of coordination movement and brain activity is still not fully understood. The current study aimed to identify activated brain regions and brain network connectivity changes for several coordinated finger movements with different difficulty levels and to correlate the brain hemodynamics and connectivity with kinematic performance.MethodsTwenty-one right-dominant-handed subjects were recruited and asked to complete circular motions of single and bilateral fingers in the same direction and in opposite directions on a plane. Kinematic data including radius and (...) angular velocity at each task and synchronized blood oxygen concentration data using functional near-infrared spectroscopy were recorded covering six brain regions including the prefrontal cortex, motor cortex, and occipital lobes. A general linear model was used to locate activated brain regions, and changes compared with baseline in blood oxygen concentration were used to evaluate the degree of brain region activation. Small-world properties, clustering coefficients, and efficiency were used to measure information interaction in brain activity during the movement.ResultIt was found that the radius error of the dominant hand was significantly lower than that of the non-dominant hand in both clockwise and counterclockwise movements. The fNIRS results confirmed that the contralateral brain region was activated during single finger movement and the dominant motor area was activated in IP movement, while both motor areas were activated simultaneously in AP movement. The Δhbo were weakly correlated with radius errors. Brain information interaction in IP movement was significantly larger than that from AP movement in the brain network in the right prefrontal cortex. Brain activity in the right motor cortex reduces motor performance, while the right prefrontal cortex region promotes it.ConclusionOur results suggest there was a significant correlation between motion performance and brain activation level, as well as between motion deviation and brain functional connectivity. The findings may provide a basis for further exploration of the operation of complex brain networks. (shrink)

The strong predominance of right-handedness appears to be a uniquely human characteristic, whereas the left-cerebral dominance for vocalization occurs in many species, including frogs, birds, and mammals. Right-handedness may have arisen because of an association between manual gestures and vocalization in the evolution of language. I argue that language evolved from manual gestures, gradually incorporating vocal elements. The transition may be traced through changes in the function of Broca's area. Its homologue in monkeys has nothing to do with (...) vocal control, but contains the so-called “mirror neurons,” the code for both the production of manual reaching movements and the perception of the same movements performed by others. This system is bilateral in monkeys, but predominantly left-hemispheric in humans, and in humans is involved with vocalization as well as manual actions. There is evidence that Broca's area is enlarged on the left side in Homo habilis, suggesting that a link between gesture and vocalization may go back at least two million years, although other evidence suggests that speech may not have become fully autonomous until Homo sapiens appeared some 170,000 years ago, or perhaps even later. The removal of manual gesture as a necessary component of language may explain the rapid advance of technology, allowing late migrations of Homo sapiens from Africa to replace all other hominids in other parts of the world, including the Neanderthals in Europe and Homo erectus in Asia. Nevertheless, the long association of vocalization with manual gesture left us a legacy of right-handedness. Key Words: cerebral dominance; gestures; handedness; hominids; language evolution; primates; speech; vocalization. (shrink)

Although gestures have surface similarities with language, there are significant organisational and neurolinguistic differences that argue against the evolutionary connection proposed by Corballis. Dominance for language and handedness may be related to a basic specialisation of the left cerebral hemisphere for target-directed behaviour and sequential processing, with the right side specialised for holistic-environmental monitoring and spatial processing.

In _ Psychiatry in the Scientific Image, _Dominic Murphy looks at psychiatry from the viewpoint of analytic philosophy of science, considering three issues: how we should conceive of, classify, and explain mental illness. If someone is said to have a mental illness, what about it is mental? What makes it an illness? How might we explain and classify it? A system of psychiatric classification settles these questions by distinguishing the mental illnesses and showing how they stand in relation to one (...) another. This book explores the philosophical issues raised by the project of explaining and classifying mental illness. Murphy argues that the current literature on mental illness -- exemplified by the Diagnostic and Statistical Manual of Mental Disorders -- is an impediment to research; it lacks a coherent concept of the mental and a satisfactory account of disorder, and yields too much authority to commonsense thought about the mind. He argues that the explanation of mental illness should meet the standards of good explanatory practice in the cognitive neurosciences, and that the classification of mental disorders should group symptoms into conditions based on the causal structure of the normal mind.

For centuries, philosophers have identified beauty with what brings pleasure. Dominic McIver Lopes challenges this interpretation by offering an entirely new theory of beauty - that beauty engages us in action, in concert with others, in the context of social networks - and sheds light on why aesthetic engagement is crucial for quality of life.

There is not one but many ways to picture the world--Australian "x-ray" pictures, cubish collages, Amerindian split-style figures, and pictures in two-point perspective each draw attention to different features of what they represent. Understanding Pictures argues that this diversity is the central fact with which a theory of figurative pictures must reckon. Lopes advances the theory that identifying pictures' subjects is akin to recognizing objects whose appearances have changed over time. He develops a schema for categorizing the different ways pictures (...) represent--the different kinds of meaning they have--and argues that that depiction's epistemic value lies in its representational diversity. He also offers a novel account of the phenomenology of pictorial experience, comparing pictures to visual prostheses like mirrors and binoculars. (shrink)

Images have power - for good or ill. They may challenge us to see things anew and, in widening our experience, profoundly change who we are. The change can be ugly, as with propaganda, or enriching, as with many works of art. Sight and Sensibility explores the impact of images on what we know, how we see, and the moral assessments we make. Dominic Lopes shows how these are part of, not separate from, the aesthetic appeal of images. His book (...) will be essential reading for anyone working in aesthetics and art theory, and for all those intrigued by the power of images to affect our lives. '...tightly focused and carefully argued... an exceptionally interesting contribution to the philosophy of art: it contains subtle, concise, and convincing discussions of a number of difficult concepts and contentious doctrines... lucid and meticulous'.

Given its brevity, Plato's Meno covers an astonishingly wide array of topics: politics, education, virtue, definition, philosophical method, mathematics, the nature and acquisition of knowledge and immortality. Its treatment of these, though profound, is tantalisingly short, leaving the reader with many unresolved questions. This book confronts the dialogue's many enigmas and attempts to solve them in a way that is both lucid and sympathetic to Plato's philosophy. Reading the dialogue as a whole, it explains how different arguments are related to (...) one another and how the interplay between characters is connected to the philosophical content of the work. In a new departure, this book's exploration focuses primarily on the content and coherence of the dialogue in its own right and not merely in the context of other dialogues, making it required reading for all students of Plato, be they from the world of classics or philosophy.

One of the few points of agreement to be found in mainstream responses to the logical and semantic problems generated by vagueness is the view that if any modification of classical logic and semantics is required at all then it will only be such as to admit underdetermined reference and truth-value gaps. Logics of vagueness including many valued logics, fuzzy logics, and supervaluation logics all provide responses in accord with this view. The thought that an adequate response might require the (...) recognition of cases of overdetermination and truth value gluts has few supporters. This imbalance lacks justification. As it happens, Jaskowski's paraconsistent discussive logic-a logic which admits truth value gluts-can be defended by reflecting on similarities between it and the popular supervaluationist analysis of vagueness already in the philosophical literature. A simple dualisation of supervaluation semantics results in a paraconsistent logic of vagueness based on what has been termed subvaluational semantics. (shrink)

Is it ethical for doctors or courts to prevent patients from making choices that will cause significant harm to themselves in the future? According to an important liberal principle the only justification for infringing the liberty of an individual is to prevent harm to others; harm to the self does not suffice.In this paper, I explore Derek Parfit’s arguments that blur the sharp line between harm to self and others. I analyse cases of treatment refusal by capacitous patients and describe (...) different forms of paternalism arising from a reductionist view of personal identity. I outline an Identity Relative Paternalistic Intervention Principle for determining when we should disallow refusal of treatment where the harm will be accrued by a future self, and consider objections including vagueness and non-identity.Identity relative paternalism does not always justify intervention to prevent harm to future selves. However, there is a stronger ethical case for doing so than is often recognised. (shrink)

This paper is a critical analysis of the concept of mental disorder recently advanced by Jerome Wakefield. Wakefield suggests that mental disorders are most aptly conceived as "harmful dysfunctions" involving two distinct and separable components: the failure of the mechanism in the person to perform a natural function for which the mechanism was designed by natural selection, and a value judgment that the dysfunction is undesirable.

We often ascribe possibility to the scenes that are displayed by mental or nonmental sensory images. The paper presents a novel argument for thinking that we are prima facie justified in ascribing metaphysical possibility to what is displayed by suitable visual images, and it argues that many of our imagery‐based ascriptions of metaphysical possibility are therefore prima facie justified. Some potential objections to the arguments are discussed, and some potential extensions of them, to cover nonvisual forms of imagery and nonmetaphysical (...) forms of possibility, are endorsed.

This book offers a bold new approach to the philosophy of art. General theories of art don't work: they can't deal with problem cases. Instead of trying to define art, we should accept that a work of art is nothing but a work in one of the arts. Lopes's buck passing theory works well for the avant garde, illuminating its radical provocations.

The paper examines the relationships between the contents of imaginative episodes and the mental images that often play a central role within them. It considers, for example, whether the presence of mental imagery is required for a mental episode to count as an imagining.

We observed that despite international declarations on child-rights, outsourced domestic girl-child labour still persists. Raising the question whether outsourced domestic girl-child labour constitutes hermeneutical injustice, we respond affirmatively. Relying on two indigenous victimology-narratives that are newspaper reports, we expose some of the horrors that the victims of outsourced domestic girl-child labour suffer. Comparing these reports with other victimology-narratives of hermeneutical injustice as reported by Miranda Fricker and Hilkje Hänel, we argue that the victims of outsourced domestic girl-child labour suffer a (...) hermeneutical gap and hermeneutical interference; and that the perpetuators of this practice, help to foster what we call ‘hermeneutical obstruction’. We recommend different counteracting measures such as: a radical feminization of educational curricula, which will allow for the introduction of the relevant hermeneutical resources that female children need in making sense of their experiences, into the classrooms and other places of learning; establishing feminist liberation agencies in all schools, religious institutions and hospitals, as ways of increasing the level of awareness about the rights of the girl-child in children and adults; feminizing legislation and legislative processes, to allow for the enactment of laws to protect the rights of the girl-child; and campaigning for a more rigorous enforcement of child-rights laws.

In this paper, I will argue that the NIMH’s new Research Domain of Criteria is a useful test of the philosophical hypothesis of eliminative materialism and demonstrates the superiority of a moderate eliminativism over integrationism, which is a rival philosophical framework for the cognitive sciences. I begin by going over the motivation for RDOC, which rests on the problems with the existing Diagnostic and Statistical Manual of Mental Disorders framework in psychiatry. Then, I introduce the main tenets of RDoC before (...) discussing eliminativism and trying to show what a moderate eliminativism looks like through the example of addiction. I then contrast that approach with intregrationism to the latter’s detriment. I end by wondering whether the broadly political consequences of eliminativism give us non-scientific reasons for resisting it, as it threatens to rob ordinary people of important means of self-description.

This chapter begins by sketching an account of morally responsible agency and the general conditions under which it may fail. We discuss how far individuals with psychiatric diagnoses may be exempt from morally responsible agency in the way that infants are, with examples drawn from a sample of diagnoses intended to make dierent issues salient. We further discuss a recent proposal that clinicians may hold patients responsible without blaming them for their acts. We also consider cognitively impaired subjects in the (...) light of related issues in moral and political theory, asking whether they have been unjustly excluded from liberal conceptions of political community due to their presumed lack of agency.

[David Charles] Aristotle, it appears, sometimes identifies well-being with one activity, sometimes with several, including ethical virtue. I argue that this appearance is misleading. In the Nicomachean Ethics, intellectual contemplation is the central case of human well-being, but is not identical with it. Ethically virtuous activity is included in human well-being because it is an analogue of intellectual contemplation. This structure allows Aristotle to hold that while ethically virtuous activity is valuable in its own right, the best life available for (...) humans is centred around, but not wholly constituted by, intellectual contemplation. /// [Dominic Scott] In Nicomachean Ethics X 7-8, Aristotle distinguishes two kinds of eudaimonia, primary and secondary. The first corresponds to contemplation, the second to activity in accordance with moral virtue and practical reason. My task in this paper is to elucidate this distinction. Like Charles, I interpret it as one between paradigm and derivative cases; unlike him, I explain it in terms of similarity, not analogy. Furthermore, once the underlying nature of the distinction is understood, we can reconcile the claim that paradigm eudaimonia consists just in contemplation with a passage in the first book requiring eudaimonia to involve all intrinsic goods.

Jennifer Radden argues that delusions play an important role in modernist epistemology, which is preoccupied with the justification and evaluation of beliefs. Another theme running through the book is the importance of culture for attribution of delusion. Beliefs that look delusional will not be treated as pathological if they are expressions of religious views or other culturally acceptable forms of life. It is hard to see why cultural acceptability should play a role in the modernist project of justification. I suggest (...) that we think less about a philosophical project of justification and turn our attention instead to commonsense judgements of the circumstances in which we see a belief as evidence of underlying pathology. I discuss cases in which unjustified beliefs are nonetheless treated as phenomena that are consistent with our views of how healthy human beings act, and suggest that alongside folk psychology we should acknowledge a folk epistemology that embraces such instances. I suggest that delusions are beliefs that folk epistemology treats as inexplicable, and that this approach solves some of the puzzles that Radden identifies as growing out of the modernist epistemic project.
