The author recounts major personal and moral tensions that arose during an 11-month period living in Ghana and shares how she has since learned to reconcile those tensions.

A systematic study of rational or justified belief, which throws fresh light on current debates about foundations and coherence theories of knowledge, the validation of induction and moral scepticism. Dr Nathan focuses attention on the largely unsatisfiable desires for active and self-conscious assurance of truth liable to be engendered by philosophical reflection about total belief-systems and the sources of knowledge. He extracts a kernel of truth from the doctrine that a regress of justification is both necessary and impossible, contrasts the (...) resultant scepticism with more familiar complaints about the inapplicability of supposedly essential cognitive concepts and explores the feasibility of non-Humean modes of consolation. This is an original and carefully constructed book, which will interest professional philosophers and advanced students of epistemology. (shrink)

Ravelingien et al1 argue that, given the restrictions that must be imposed on recipients of xenotransplanted organs, we should conduct clinical trials of xenotransplantation only on patients in a persistent vegetative state. I argue that there is no ethical barrier to using terminally ill patients instead. Such patients can choose to waive their rights to the liberties that xenotransplantation would probably restrict; it is surely rational to prefer to waive your rights rather than to die, and permissible to allow patients (...) to make this choice.Perhaps the single most important advance in the history of moral thought occurred when it came to be generally recognised that all people are protected by rights that are inviolable, at least without their consent. The precise nature and content of these rights is controversial, but there is a consensus among reasonable people over their core. We all have a right to life, to liberty, to security of person and to equality before the law. Other rights—so-called positive rights, such as the right to economic security, or cultural rights, for instance—may be controversial, but we all agree at least on these.Ravelingien et al1 therefore seem to be on solid ground when they conclude that it would not be permissible to use living persons as subjects in clinical trials of xenotransplantation, as such trials, potentially or actually, result in the violation of the core human rights of the subjects. Their argument is as follows:" Xenotransplantation carries with it a currently unquantifiable risk of the transmission of viruses, from the animal that is the source of the organ transplanted, to the human recipient. Such viruses could have potentially catastrophic consequences, up to and including triggering a global and devastating pandemic. Therefore, it would be necessary to monitor the health status of recipients of … ". (shrink)

The article considers modern transformations of the ideas concerning subject’s cognitive abilities towards object because of the emergence and development of artificial intelligence (AI) technologies. The developments of scientists and engineers from National Research University of Electronic Technology (Moscow, Russia) in the field of artificial intelligence have been taken as a foundation and material of this research. Their analysis allows making a conclusion that the humanity is rather far from the realization of ‘strong artificial intelligence’. We need a qualitative breakthrough (...) in AI material and technological basis for it. Applying ‘model-dependent realism’ by S. Hawking in the course of the speculations in the article, the author concludes that the purpose of cognition in modern science is not to describe an objective reality, but to organize its subjective perception by some definite way. So, the purpose of cognition is the perfection of cognition models permitting a subject ‘to capture’ the reality. This idea is completely confirmed by Maturana and Varela’s autopoiesis theory and von Foerster’s ‘second-order cybernetics’. The article drafts some prospects of moving away from post-nonclassical scientific thinking in its current understanding, because the development of AI technologies results in ‘blurring’ borders of subjectivity in the cognition process. The author concludes that the modern world is moving in another epistemological paradigm where a new scientific revolution is inevitable. (shrink)

Stiff Person Syndrome is a rare autoimmune disorder associated with antibodies against glutamic acid decarboxylase, the key enzyme in γ -aminobutyric acid synthesis. In order to investigate the role of cerebral benzodiazepinereceptor binding in SPS, we performed [ 11 C]flumazenil positron emission tomography in a female patient with SPS compared to nine healthy controls. FMZ is a radioligand to the postsynaptic central benzodiazepine receptor which is co-localized with the GABA-A receptor. In the SPS patient, we found a global reduction of (...) cortical FMZ binding. In addition, distinct local clusters of reduced radiotracer binding were observed. These data provide first in vivo evidence for a reduced postsynaptic GABA-A receptor availability which may reflect the loss of GABAergic neuronal inhibition in SPS. (shrink)

This paper describes the topological aspect of a logic-based, artificial intelligence approach to formalising the qualitative description of spatial properties and relations, and reasoning about those properties and relations. This approach, known as RCC theory, has been under development for several years at the University of Leeds. The main rationale for this project is that qualitative descriptions of spatial properties and relationships, and qualitative spatial reasoning, are of fundamental importance in human thinking about the world: even where quantitative spatial data (...) are most important, they must be attached to the components of a perceived spatial structure if we are to make use of them. RCC theory covers other qualitative aspects of spatial description and reasoning, but the topological properties and relations of spatially extended entities are fundamental to our work. The topological formalisms used by mathematicians are, in general, not well suited to the task of formalising the kinds of ‘common-sense’ or ‘everyday’ qualitative spatial description and reasoning which are our primary interest. Nevertheless, we must come to grips with the concepts of topology as practised by mathematicians if we are not to risk constantly ‘reinventing wheels’. (shrink)
