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)

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.

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)

Die Herrschaft des Behaviorismus in der Psychologie ist gebrochen! Das ist die Ausgangsthese dieses Buches, die im Rahmen des Modells revolutionärer Wissenschaftsentwicklung (Kuhn) als Behauptung eines Paradigmawechsels präzisiert wird. Die Argumentation beschränkt sich nicht nur auf den Nachweis des Niedergangs des Behaviorismus, sondern gibt auch konstruktiv das mögliche neue Paradigma an: als Psychologie des reflexiven Subjekts, das wie der Wissenschaftler (subjektive) Theorien aufstellt, überprüft, bewertet. Der Aufriss einer solchen Psychologie des epistemischen Subjekts unter allgemein-, sozial-, pädagogisch- und klinisch-psychologischem Aspekt thematisiert (...) vor allem: die Rationalität der Reflexionen, Normenkritik und -begründung im Austausch von wissenschaftlichen und naiven Theorien sowie die Berücksichtigung von Reflexivität in der therapeutischen Praxis. Die Rückwendung dieser pychologisch-metatheoretischen Perspektiven auf die Wissenschaftstheorie führt auch zu einer neu. (shrink)

Open peer commentary on the target article “Who Conceives of Society?” by Ernst von Glasersfeld. Excerpt: In the face of modern neuroscience we should give up on constructivism, even more so on radical constructivism, and stick to the physical and psychological reality given in science and daily life, even if it is the brain’s illusion from associative networks. The illusion of constructivism may hurt!

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)
