I address the question: ‘Are acts of the ritual slaughter of animals, of the kind recently engaged in by the Yengeni family, morally justifiable?’ Using the Yengeni incident as a springboard for my discussion, I focus on the moral question of the relative weight of two competing ethical claims. I weigh the claim that we have an obligation not to cause animals pain without good reason against the claim by cultures that traditional practices, such as the one under discussion, are (...) morally justifiable on the basis of the moral goods obtained through cultural identification and participation. I attempt to show that claims justifying practices on the basis of culture are not strong enough to outweigh the prima facie wrong of causing non-human animals unnecessary pain. (shrink)

There is general acknowledgement that both the anterior cingulate and orbitofrontal cortex are implicated in reinforcement-guided decision making, and emotion and social behaviour. Despite the interest that these areas generate in both the cognitive neuroscience laboratory and the psychiatric clinic, ideas about the distinctive contributions made by each have only recently begun to emerge. This reflects an increasing understanding of the component processes that underlie reinforcement- guided decision making, such as the representation of reinforcement expectations, the exploration, updating and representation (...) of action values, and the appreciation that choices are guided not just by the prospect of reward but also by the costs that action entails. Evidence is emerging to suggest that the anterior cingulate and orbitofrontal cortex make distinct contributions to each of these aspects of decision making. (shrink)

One of the goals of computerized tutoring systems is to optimize the learning of facts. Over a hundred years of declarative memory research have identified two robust effects that can improve such systems: the spacing and the testing effect. By making optimal use of both and adjusting the system to the individual learner using cognitive models based on declarative memory theories, such systems consistently outperform traditional methods. This adjustment process is driven by a continuously updated estimate of the rate of (...) forgetting for each item and learner on the basis of the learner's accuracy and response time. In this study, we investigated to what extent these estimates of individual rates of forgetting are stable over time and across different materials. We demonstrate that they are stable over time but not across materials. Even though most theories of human declarative memory assume a single underlying rate of forgetting, we show that, in practice, it makes sense to assume different materials are forgotten at different rates. If a computerized, adaptive fact-learning system allowed different rates of forgetting for different materials, it could adapt to individual learners more readily. (shrink)

This article suggests evidence for and reasons why prior acquisition may either facilitate or inhibit acquisition of a new construction. It investigates acquisition of the German passive and future constructions which contain a lexical verb with either the auxiliary sein “to be” or werden “to become”, and are related through these to potential supporting constructions. We predicted that a supported construction should be acquired earlier, faster, and unusually rapidly. An inhibited construction should show an extended depressed usage. We analyzed a (...) dense corpus of a German boy between 2;0 and 5;0. He acquired the sein- before the werden-passive. The former was supported by his prior acquisition of the sein copula, whereas the werden-passive itself supported one werden copula construction. He acquired the werden-future extremely slowly due to the hindrance of a semantically identical construction. These results fit with an emergentist approach in which apparently “sudden” acquisition is still due to gradual learning mechanisms. (shrink)

Even though most theories of human declarative memory assume a single underlying rate of forgetting, we show that, in practice, it makes sense to assume different materials are forgotten at different rates. If a computerized, adaptive fact‐learning system allowed different rates of forgetting for different materials, it could adapt to individual learners more readily. (shrink)

Putative counterexamples to the Principle of Identity of Indiscernibles (PII) are notoriously inconclusive. I establish ground rules for debate in this area, offer a new response to such counterexamples for friends of the PII, but then argue that no response is entirely satisfactory. Finally, I undermine some positive arguments for PII.

A historical investigation of the exclusion of Africa and Asia from modern histories of philosophy.

Mental health research and care in the twenty first century faces a series of conceptual and ethical challenges arising from unprecedented advances in the neurosciences, combined with radical cultural and organisational change. The Oxford Textbook of Philosophy of Psychiatry is aimed at all those responding to these challenges, from professionals in health and social care, managers, lawyers and policy makers; service users, informal carers and others in the voluntary sector; through to philosophers, neuroscientists and clinical researchers. Organised around a series (...) of case studies in five key topic areas - concepts of disorder, the philosophical history of psychopathology, philosophy of science, ethics and philosophical value theory, and philosophy of mind - the book provides a detailed introduction to the field and a framework for study and skill development. Each case study is supported by selected readings from both philosophy and mental health, thinking skills exercises, self-test questions, key learning points and detailed guides to further reading. There is an introduction for philosophers to classification and descriptive psychopathology, and for practitioners to philosophical methods (including logic). The philosophical topics covered include philosophical methods (analytic and Continental); phenomenology, hermeneutics and existentialism, logical empiricism and its successors; idealism and realism; reasons and causes; and modern theories of mind and brain, free will and personal identity. Topics from mental health include psychiatry and 'anti-psychiatry'; Jaspers' psychopathology and the new neurosciences; the future of psychiatric classifications; strengths-based approaches, recovery practice, social inclusion and diversity; and key topics in psychopathology, such as delusion, autism, disorders of volition, thought insertion and other experiences in schizophrenia. The Oxford Textbook of Philosophy of Psychiatry aims to secure the skills-base of the discipline by bringing philosophers closer to the realities of practice in mental health, and mental health practitioners closer to the resources of philosophy as a partner to the sciences in responding to the challenges of twenty-first century mental health and social care.

This book is a defense of modal realism; the thesis that our world is but one of a plurality of worlds, and that the individuals that inhabit our world are only a few out of all the inhabitants of all the worlds. Lewis argues that the philosophical utility of modal realism is a good reason for believing that it is true.

With biobank research on the increase and the history of exploitation in Africa, it has become necessary to manage the transfer of human tissues across national boundaries. There are many accepted templates of Material Transfer Agreements that currently exist internationally. However, these templates do not address the specific concerns of South Africa and even of Africa as a continent. This article will examine three significantly important ethico-legal concepts that were deliberated and carefully adapted by a South African Institution to suit (...) the transfer of Human Biological Materials and associated data for biobank research, namely: informed consent; benefit sharing arrangements; and ownership together with intellectual property rights in human tissues. The discussion includes an analysis of current practice; the ethico-legal challenges in the South African/African context; the decisions made with regard to how the related ethico-legal challenges were addressed in the MTA; and justifications for implementing these decisions. The processes considered could be of benefit to other developing world countries who consider it necessary to manage the transfer of HBMs across national boundaries. (shrink)

I give an account how the principle of ‘respect for autonomy’ dominates the field of bioethics, and how it came to triumph over its competitors, ‘respect for persons’ and ‘respect for free power of choice’. I argue that ‘respect for autonomy’ is unsatisfactory as a basic principle of bioethics because it is grounded in too individualistic a worldview, citing concerns of African theorists and other communitarians who claim that the principle fails to acknowledge the fundamental importance of understanding persons within (...) the nexus of their communal relationships. I defend the claim that ‘respect for persons’ is a more appropriate principle, as it is able to acknowledge both individual decision making and the essential relationality of persons. I acknowledge that my preference for ‘respect for persons’ is problematic because of the important debate around the definition of ‘personhood’ in bioethics discourse. Relying on Thaddeus Metz's conception of moral status, I propose a relational definition of personhood that distinguishes between persons with agency and persons without agency, arguing that we have different moral obligations to these distinct categories of persons. I claim that this conception of personhood is better able to accommodate our moral intuitions than conventional approaches, and that it is able to do so without being speciesist or question-begging.

There is a pervasive presumption that African thought is inherently anthropocentric and has little to contribute to environmental ethics. Against this view, a promising African environmentalism can be be found in a belief in a fundamental interrelatedness between natural objects. What establishes moral considerability on this African view is that entities are part of the interconnected web of life. This position accords moral standing to all living things, groups of living things, as well as inanimate natural entities. This view is (...) not only plausible, but also theoretically appealing.

Philosophy has much to offer psychiatry, not least regarding ethical issues, but also issues regarding the mind, identity, values, and volition. This has become only more important as we have witnessed the growth and power of the pharmaceutical industry, accompanied by developments in the neurosciences. However, too few practising psychiatrists are familiar with the literature in this area. -/- The Oxford Handbook of Philosophy and Psychiatry offers the most comprehensive reference resource for this area ever published. It assembles challenging and (...) insightful contributions from key philosophers and others to the interactive fields of philosophy and psychiatry. Each contributions is original, stimulating, thorough, and clearly and engagingly written - with no potentially significant philosophical stone left unturned. Broad in scope, the book includes coverage of several areas of philosophy, including philosophy of mind, science, and ethics. For philosophers and psychiatrists, The Oxford Handbook of Philosophy and Psychiatry is a landmark publication in the field - one that will be of value to both students and researchers in this rapidly growing area.

Objective: The establishment of patient-centered measures capable of empirically determining meaningful cognitive change after surgery can significantly improve the medical care of epilepsy patients. Thus, this study aimed to develop reliable change indices (RCIs) and standardized regression-based (SRB) change norms for a comprehensive neuropsychological test battery in the German language. Methods: Forty-seven consecutive patients with temporal lobe epilepsy underwent neuropsychological assessments, both before and 12 months after surgery. Practice-effect-adjusted RCIs and SRB change norms for each test score were computed. To (...) assess their usefulness, the presented methods were applied to a clinical sample, and binary logistic regression analyses were conducted to model the odds of achieving improvement in quality of life (QOL) after surgery. Results: The determined RCIs at 90% confidence intervals, and the SRB equations for each test score included in the test battery are provided. Cohen’s kappa analyses revealed a moderate mean agreement between the two measures, varying from slight to almost perfect agreement across test scores. Using these measures, a negative association between improvement in QOL and decline in verbal memory functions after surgery was detected. Significance: To the best of our knowledge, this study is the first to provide RCIs and SRB change norms necessary for the objective determination of neuropsychological change in a comprehensive test battery in the German language, facilitating the individual monitoring of improvement and decline in each patients’ cognitive functioning and psychosocial situations after epilepsy surgery. The application of the described measures revealed a strong negative association between improvement in QOL and decline in verbal memory functions after surgery. (shrink)

Contrary to a pervasive presumption of anthropocentricism in African thought, I identify an emphasis on the interrelatedness or interconnectedness of everything in nature, and argue that this is best construed as a rejection of anthropocentrism, and as something similar in conception to, and yet distinct from, holist perspectives. I propose that this strand of African thought, suitably reconstructed, should be construed as providing the basis for a promising non-anthropocentric African environmentalism. I name this position 'African Relational Environmentalism', and suggest that (...) it is what distinguishes this position from holism that can most enrich environmental ethics. -/- . (shrink)

Are mystical experiences primarily formed by the mystic's cultural background and concepts, as modern day "constructivists" maintain, or do mystics in some way transcend language, belief, and culturally conditioned expectations? Do mystical experiences differ in the different religious traditions, as "pluralists" contend, or are they identical across cultures? Twelve contributors here attempt to answer these questions through close examination of a particular form of mystical experience, "Pure Consciousness"--the experience of being awake but devoid of intentional content for consciousness. The contributors (...) analyze pure consciousness and other mystical experiences from historical Hindu, Buddhist, Christian, and Jewish sources, as well as from modern mystics. They demonstrate that pure consciousness poses serious conceptual problems for a contructivist understanding of mysticism. Revealing the inconsistencies and inadequacies of current models, they make significant strides towards developing new models for the phenomenon of mysticism, breaking new ground for our understanding of mysticism and of human experience in general.

It is advisable to treat some sorts of discourse about fiction with the aid of an intensional operator "in such-And-Such fiction...." the operator may appear either explicitly or tacitly. It may be analyzed in terms of similarity of worlds, As follows: "in the fiction f, A" means that a is true in those of the worlds where f is told as known fact rather than fiction that differ least from our world, Or from the belief worlds of the community in (...) which the fiction originated.
