There is growing evidence that dopamine replacement therapy (DRT) used to treat Parkinson’s Disease can cause compulsive behaviours and impulse control disorders (ICDs), such as pathological gambling, compulsive buying and hypersexuality. Like more familiar drug-based forms of addiction, these iatrogenic disorders can cause significant harm and distress for sufferers and their families. In some cases, people treated with DRT have lost their homes and businesses, or have been prosecuted for criminal sexual behaviours. In this article we first examine the evidence (...) that these disorders are caused by DRT. If it is accepted that DRT cause compulsive or addictive behaviours in a significant minority of individuals, then the following ethical and clinical questions arise: Under what circumstances is it ethical to prescribe a medication that may induce harmful compulsive behaviours? Are individuals treated with DRT morally responsible and hence culpable for harmful or criminal behaviour related to their medication? We conclude with some observations of the relevance of DRT-induced ICDs for our understanding of addiction and identify some promising directions for future research and ethical analysis. (shrink)
The logic of fiction has been a stand-alone research programme only since the early 1970s.1 It is a fair question as to why in the first place fictional discourse would have drawn the interest of professional logicians. It is a question admitting of different answers. One is that, since fictional names are “empty”, fiction is a primary datum for any logician seeking a suitably comprehensive logic of denotation. Another answer arises from the so-called incompleteness problem, exemplified by the fact (or (...) apparent fact) that some fictional sentences – think of “Sherlock Holmes’ mother was nick-named ‘Polly’” − are neither true nor false. These are sentences to command the attention of logicians who work on non-bivalent logics. A further spur to logical engagement is the supposed fictionality of certain kinds of ideal models in science and certain classes of mathematical objects. No doubt, there are other features of fictional discourse that provide the logician with a natural entré, but perhaps it would also be correct to say that the fiction’s biggest draw for logicians is that our quite common beliefs about the fictional constitute what Nicholas Rescher calls “aporetic clusters”, so named after the Latinized Greek aporos for “impassable”.2 An aporetic cluster is a set of claims such that..

The majority of commentators agree that the time to focus on embodiment has arrived and that the disembodied approach that was taken from the birth of artificial intelligence is unlikely to provide a satisfactory account of the special features of human intelligence. In our Response, we begin by addressing the general comments and criticisms directed at the emerging enterprise of deictic and embodied cognition. In subsequent sections we examine the topics that constitute the core of the commentaries: embodiment mechanisms, dorsal (...) and ventral visual processing, eye movements, and learning. (shrink)
'Poverty itself is a violation of numerous basic human rights.' (Mary Robinson, former UN High Commissioner on Human Rights) -/- The idea that freedom from poverty is a basic human right that gives rise to moral and legal obligations of governments and other actors has received increased international attention in recent years. Mary Robinson, the former UN High Commissioner for Human Rights, has pushed the international agenda on poverty and human rights forward by characterizing extreme poverty as one of the (...) key human rights problems that the world faces. The recognition of poverty as a human rights issue is also increasingly reflected in the work of international organizations such as the United Nations Development Programme (UNDP) and the United Nations Children's Fund (UNICEF), and of campaigning organizations such as Oxfam, Human Rights Watch, and Amnesty International. -/- In Poverty and Human Rights Vizard analyses the importance of the work of the Nobel Laureate Amartya Sen for contemporary debates about poverty and human rights. Bringing together perspectives from ethics, economics, and international law, Vizard provides a detailed and concise analysis of Sen's contributions and examines the ways in which his work has promoted cross-fertilization and integration across traditional disciplinary divides. She demonstrates that Sen has made a major contribution to the development of an 'interdisciplinary bridge' between human rights and theoretical and empirical economics, and to the establishment of poverty as a human rights issue. -/- Vizard demonstrates that Sen's work has deepened and expanded human rights discourse in important and influential ways. In ethics, Sen is shown to have challenged the exclusion of poverty, hunger, and starvation from the characterization of fundamental freedoms and human rights, and to have contributed to the development of a framework in which authoritatively recognized international standards in this field can be meaningfully conceptualized and coherently understood. In economics, Sen is shown to have set out a far-reaching critique of standard frameworks that fail to take account of fundamental freedoms and human rights, and to have moved the economics and human rights agenda forward by pioneering the development of new paradigms and approaches which focus on these concerns.
