The decision to undertake this volume was made in 1971 at Lake Como during the Varenna summer school ofthe Italian Physical Society, where Professor Leon Rosenfeld was lecturing on the history of quantum theory. We had long been struck by the unique blend of epistemological, histori cal and social concerns in his work on the foundations and development of physics, and decided to approach him there with the idea of publishing a collection of his papers. He responded enthusiastically, and agreed (...) to help us select the papers; furthermore, he also agreed to write a lengthy introduction and to comment separately on those papers that he felt needed critical re-evaluation in the light of his current views. For he was still vigorously engaged in both theoretical investigations of, and critical not reflections on the foundations of theoretical physics. We certainly did conceive of the volume as a memorial to a 'living saint', but rather more practically, as a useful tool to place in the hands of fellow workers and students engaged in wrestling with these difficult problems. All too sadly, fate has added a memorial aspect to our labors. We agreed that in order to make this book most useful for the con temporary community of physicists and philosophers, we should trans late all non-English items into English. (shrink)

The aging of the population presents modern Western society with a variety of different challenges, especially in the areas of health and medicine. On the one hand, there is the demand of the elderly patients to receive medical treatments that are supposed to improve or preserve the existing quality of life and to prevent the extension of a life without quality, with suffering and pain. On the other hand, aging is accompanied by the appearance and exacerbation of chronic illnesses, reduces (...) the treatment benefits of medical activities and increases the risks of irreversible physical dependence. Furthermore, the lack of consensus among the physicians regarding the willingness of treatment and the proper timing of the treatment of the elderly – pose questions about the quality of the treatment for the elderly. Thus, in the opinion of different care-providers and in comparison to other age groups in modern Western society, the elderly do not enjoy the treatment advantages of medical activities proven in the treatment of other age groups in society.
