A laboratory-testable, solid-state Maxwell demon is proposed that utilizes the electric field energy of an open-gap p-n junction. Numerical results from a commercial semiconductor device simulator (Silvaco International–Atlas) verify primary results from a 1-D analytic model. Present day fabrication techniques appear adequate for laboratory tests of principle.

"There are no paradoxes in mathematics," says Kurt Gödel. Moreover, Gödel seems to be right on this count. That is, there are no paradoxes, in the strict sense of the word, internal to the known and available body of mathematical knowledge. But while there are no paradoxes in mathematics, there certainly is an embarrassing bag of difficulties when we come to the application of mathematical concepts to the physical world. Of these, perhaps the most unruly offenders of all are the (...) problems proposed about 2500 years ago by Zeno and which, in modern idiom, have to do with the proper mathematical treatment of phenomena involving change and motion, and the physical meaning—if any—which may be assigned to convergent infinite series. At each stage in the growth of mathematical knowledge since their formulation Zeno's paradoxes have been the subject of some alleged resolution. Now Grünbaum contributes to this tradition, and it must be said that he makes a strong case. The weapons in the intellectual arsenal which Grünbaum brings to bear upon Zeno include such sophisticated devices as measure theory, but the weak link in the argument is in the first chapter where the author presents his somewhat psychologistic theory of temporal becoming. Grünbaum has a great many interesting things to say in later chapters about infinite processes, quantum mechanics, and Hilary Putnam. This is a first-rate contribution to the philosophy of physics.—H. P. K. (shrink)

The twentieth century has witnessed an unprecedented 'crisis in the foundations of mathematics', featuring a world-famous paradox (Russell's Paradox), a challenge to 'classical' mathematics from a world-famous mathematician (the 'mathematical intuitionism' of Brouwer), a new foundational school (Hilbert's Formalism), and the profound incompleteness results of Kurt Gödel. In the same period, the cross-fertilization of mathematics and philosophy resulted in a new sort of 'mathematical philosophy', associated most notably (but in different ways) with Bertrand Russell, W. V. Quine, and Gödel himself, (...) and which remains at the focus of Anglo-Saxon philosophical discussion. The present collection brings together in a convenient form the seminal articles in the philosophy of mathematics by these and other major thinkers. It is a substantially revised version of the edition first published in 1964 and includes a revised bibliography. The volume will be welcomed as a major work of reference at this level in the field.

Peter Abelard (1079–1142 ce) was the most wide‐ranging philosopher of the twelfth century. He quickly established himself as a leading teacher of logic in and near Paris shortly after 1100. After his affair with Heloise, and his subsequent castration, Abelard became a monk, but he returned to teaching in the Paris schools until 1140, when his work was condemned by a Church Council at Sens. His logical writings were based around discussion of the “Old Logic”: Porphyry's Isagoge, aristotle'S Categories and (...) On Interpretation and boethius'S textbook on topical inference. They comprise a freestanding Dialectica (“Logic”; probably c.1116), a set of commentaries (known as the Logica [Ingredientibus], c. 1119) and a later (c. 1125) commentary on the Isagoge (Logica Nostrorum Petititoni Sociorum or Glossulae). In a work Abelard called his Theologia, issued in three main versions (between 1120 and c.1134), he attempted a logical analysis of trinitarian relations and explored the philosophical problems surrounding God's claims to omnipotence and omniscience. The Collationes (“Debates,” also known as “Dialogue between a Christian, a Philosopher and a Jew”; probably c.1130) present a rational investigation into the nature of the highest good, in which the Christian and the Philosopher (who seems to be modeled on a philosopher of pagan antiquity) are remarkably in agreement. The unfinished Scito teipsum (“Know thyself,” also known as the “Ethics”; c.1138) analyses moral action. (shrink)

Hilary Putnam first published the consistency objection against Ludwig Wittgenstein’s account of mathematics in 1979. In 1983, Putnam and Benacerraf raised this objection against all conventionalist accounts of mathematics. I discuss the 1979 version and the scenario argument, which supports the key premise of the objection. The wide applicability of this objection is not apparent; I thus raise it against an imaginary axiomatic theory T similar to Peano arithmetic in all relevant aspects. I argue that a conventionalist (...) can explain the consistency of T and suggest that an analogous explanation can be provided for the consistency of Peano arithmetic. (shrink)

OBJECTIVES: To study the resuscitation preferences, choice of decision-maker, views on the seeking of patients' wishes and determinants of these of elderly hospital in-patients. DESIGN: Questionnaire administered on admission and prior to discharge. SETTING: Two acute geriatric medicine units (Southampton and Poole). PARTICIPANTS: Two hundred and fourteen consecutive consenting mentally competent patients admitted to hospital as emergencies. RESULTS: Resuscitation was wanted by 60%, particularly married and functionally independent patients and those who had not already considered it. Not wanted resuscitation was (...) associated with lack of social contacts. Sixty-seven per cent welcomed enquiry about their preferences and 78% wanted participation in decision, 43% as sole decision-maker. Wishing to choose oneself was associated with not wanting resuscitation, prior knowledge of it, and lack of a spouse. Patients' opinions remained stable during their admission. CONCLUSIONS: Discussion of resuscitation is practical on hospital admission without causing distress and the views expressed endure through the period of hospitalisation. Elderly patients' attitudes depend partly on personal health and social circumstances. This may assist doctors when patients are unable to participate themselves. (shrink)

Context: This conceptual paper tries to tackle the advantages and the limitations that might arise from including second-order science into global climate change sciences, a research area that traditionally focuses on first-order approaches and that is currently attracting a lot of media and public attention. Problem: The high profile of climate change research seems to provoke a certain dilemma for scientists: despite the slowly increasing realization within the sciences that our knowledge is temporary, tentative, uncertain, and far from stable, the (...) public expectations towards science and scientific knowledge are still the opposite: that scientific results should prove to be objective, reliable, and authoritative. As a way to handle the uncertainty, scientists tend to produce “varieties of scenarios” instead of clear statements, as well as reports that articulate different scientific opinions about the causes and dynamics of change for this specific field of research.

Doctors are regularly confronted with requests for sterilisation of mentally handicapped people who cannot give consent for themselves. They ought to act in a medical vacuum because there doesn't exist a consensus about a model for decision making on this matter. In this article a model for decision making is proposed, based on a review of the literature and our own research data. We have attempted to select and classify certain factors which could enable us to arrive at an ethically (...) justifiable method of making a medical decision. In doing so we distinguish two major criteria: heredity and parenting competence, and six minor criteria: conception risk, IQ, age, personality, medical aspects and prognosis and finally support and guidance for the mentally handicapped person. The major criteria give rise to a "situation of necessity". In this situation the physician is confronted with a conflict of values and interests. The minor criteria are of an entirely different ethical order. They can only be considered once the major criteria have created a "situation of necessity". Ultimately it comes down to deciding whether the benefits of sterilisation outweigh the drawbacks and whether the means are appropriate to the end, where efficient contraception is the end and irreversible sterilisation is the means. (shrink)

Upshot: For communicating second-order science, von Foerster’s ethical imperative provides a viable starting point. Proceeding from this, we plead in favour of emphasising the common grounds of diverging scientific opinions and of various approaches in second-order science instead of focussing on the differences. This will provide a basis for communication and stimulate scientific self-reflection.

One approach to the analysis of ethical dilemmas in medical practice uses the “four principles plus scope” approach. These principles are: respect for autonomy, beneficence, non-maleficence and justice, along with concern for their scope of application. However, conflicts between the different principles are commonplace in psychiatric practice, especially in forensic psychiatry, where duties to patients often conflict with duties to third parties such as the public. This article seeks to highlight some of the specific ethical dilemmas encountered in forensic psychiatry: (...) the excessive use of segregation for the protection of others, the ethics of using mechanical restraint when clinically beneficial and the use of physical treatment without consent. We argue that justice, as a principle, should be paramount in forensic psychiatry, and that there is a need for a more specific code of ethics to cover specialised areas of medicine like forensic psychiatry. This code should specify that in cases of conflict between different principles, justice should gain precedence over the other principles. (shrink)

The Reverend Hozen Seki, President of the American Buddhist Academy, says in his two-page preface that this book is the result of the transcription of five lectures given by Suzuki in the New York Buddhist Church in 1958. It is a detailing of Suzuki's own personal view of what Shin Buddhism is. This is the system that stems from the Japanese saint Shinran of the thirteenth century who was a follower of Honen, the founder of the Pure Land doctrine in (...) Japan. The aim of the book is not to trace down the background of the Pure Land teaching in India, nor is it to present Shinran's teaching as is. Rather, it is an expression of Suzuki's own insights into the Pure Land teaching.--P. J. H. (shrink)

This is a very good translation of the Bhagavad Gïtä, Song of the Lord, a highly revered text for Hindus upon which the great teachers of Vedanta, Shankara, Ramanuja, and Madhva, have written commentaries. Thus, it is a source text which in this well-arranged paperback edition is a good buy. Eleven terms are left in the Sanskrit and are defined in the introduction, which includes other introductory notes. At the end are thirty-four pages of essays on the Nature of Karma (...) Yoga, the Meta-Theological Structure, the Value of Ceremonial Religion, and Freedom and Determinism. The essays are not overly technical and thus are readable by all, making this an excellent edition for the classroom and for those who want an introduction to Hindu religion, or Indian culture.--P.

This is a well-written analysis of the interpreters and interpretations of the Buddhist nirvana from the West. The first chapter treats the West's encounters with Buddhism before 1800, Marco Polo, etc. The remainder of the book deals with the interpretations of nirvana by Eugène Burnouf, Friedrich Max Müller, James D'Alwis, Robert Caesar Childres, Schopenhauer, Wagner, Nietzsche, Hermann Oldenberg, the Rhys Davidses, La Vallée Poussin, and Stcherbatsky. The author's own opinion is given in a few pages at the end of the (...) book; however, his opinion is not so much an exposition of nirvana but a short essay on the methodology of a study of nirvana. He quotes Richard Robinson to bring home his point that this long array of scholars could not forsake their cultural bias and that one needs therefore to approach non-Western ideas from the inside of a non-Western culture. Welbon's intention is to present an outline of the history of Western discussions on the meaning of the Buddhist nirvana. His research is thorough; his presentation is clear; this is a chronicle of heroic but club-footed attempts to learn about a non-Western idea. The book should be read by all aspiring Buddhologists, for it will convince them of the absolute necessity of learning the language of a Buddhist culture and of searching out qualified native informants. Its value for non-Buddhologists is not to learn more about nirvana but to learn the history of this burgeoning study. Welbon has admirably succeeded in his aim; he has concisely presented Western opinion on nirvana up to World War II.--P. J. H. (shrink)

This book is an explication of a Westerner's understanding of Buddhism. Though the section headings, "Basic Buddhism," "Deeper Truths of Buddhism," and "Zen Buddhism" might suggest that the author is seeking to explain Buddhism on its own grounds, the author has not intended such. He is seeking to make Buddhism available to Westerners through explaining his own acceptance of the Buddhist way. Thus his book explains no particular school within Buddhism and is not very helpful as a key to Buddhism (...) as it is and was in Asia. Rather it is the culmination of a life's study of the subject and a personal confession of the author's own beliefs. The book is interspersed with ten poems written by the author called "Suffering," "Deck Chair, Brighton," "When I am Dead," "Youth in Age," "We Live in Boxes," "In Search of Nothing," "Rootless Thought," "Beyond," "Jijimuge," and "The Void is Full." The book is best suited for those whose interest in Buddhism is very light and who would prefer to read about a westerner's Buddhism.--P. J. H. (shrink)

This is an explanation of the New Nyäya system of Indian logic. The first two chapters are an introduction to the main topics of Navya-nyäya logic, relations, absence, definition, inference, quantifiers and limitors, accident, and the theory of pervasion. Following are the text, transliteration, translation, and commentary of Anumitinirüpana and Vyäptiväda by Gangeäopädhyäya. Its audience is strictly limited to those who are profoundly interested in and acquainted with logical theory. The style is lucid and will provide interesting insights for the (...) professional: however, knowledge of Sanskrit is not required. For those who are familiar with the symbols of mathematical logic, symbolic interpretations are given from time to time.--P. J. H. (shrink)

This study, under the title of an explanation of the New Nyäya views on negation, deals with the Navya-nyäya as a whole. The peculiarity of their theory of negation is that one can see the absence of an object in a given place. It includes the Sanskrit texts and translations of the Abhäva-väda of Gangesa and the Nañ-väda of Raghunätha. Though written for both Sanskritists and philosophers, the frequent use of Sanskrit terms almost requires that the reader be a Sanskritist--though (...) by keeping in mind the translations, previously given, it could be valuable. This is not an exposition of logic for beginners, but an exposition for scholars of a particular system. Renditions into modern logic are given throughout. Chapter headings include: On Cognition; The Content of Cognition and the Meaning Problem; On Relation; The Counterpositive of an Absence; The Ontological Status of Content-ness; The Relational Adjuncts; The Limitors and Quantificational Logic; Circularity; On Negation.--P.

These are the first two of a series of three volumes on Buddhism in modern China; the first deals with the system and institutions of modern Chinese Buddhism, the second with its history. The third volume which is yet to be published will deal with Buddhism in China under the communists. The books are amazingly well written; they show excellent research, much of which was in interviewing monks who had escaped from China. The presentation is well ordered, and the author's (...) style makes even what one would think was uninteresting fascinating. His own divisions best explain what the volumes contain. The first is divided into two parts, Monastic Institutions and the Individual Buddhist. The first part contains chapters on the people of the monastery, the meditation hall, the Buddha recitation hall, observance of the rules, hereditary and branch temples, the abbot, rites for the dead, and the economy of monasteries. The second part on the Individual Buddhist contains chapters on entering the sangha, the monastic career, the lay Buddhist, and the nature of the system. His account shows, contrary to the usual view, that Chinese Buddhism up to the time of communist take-over was still a vibrantly practiced religion. The second volume takes up the problem of the so-called revival of Buddhism in China beginning around the turn of the century. The chapter headings are: the beginnings of the revival, the struggle for national leadership, T'ai-hsü, the lay Buddhist movement, building and publishing, Buddhist education, social action by the sangha, sangha and state, foreign contacts, sects and dissension, Christian stereotypes and Buddhist realities, the meaning of the revival, and a postscript. The "revival" is shown to be mainly a lay movement and a reaction to political pressures which probably would have brought about the diminishment of Buddhism in China even if the communists had not taken over. As with the first volume there is here very little explanation of Buddhist doctrine which the author considered to be beyond the scope of the book. Both volumes warrant repeating that the author researched his topic thoroughly and then wrote his story in excellent prose. Highly recommended.--P. J. H. (shrink)
