It may be seen, then, that if one was prepared to accept the existence of insulating sheaths on the nerves, all the arguments raised against the proposed identification of the nervous and electrical fluids, except one, could be answered satisfactorily. The single exception involved the question of how an electrical disturbance in the brain could be confined to a single nerve, and, as was indicated earlier, it was scarcely fair to hold this sort of objection against the electrical theory alone. (...) In that case, there remained no convincing argument to show why one should not accept the identification of the two fluids. On the other hand, of course, it remained an open question as to whether there was any convincing argument to show why one should accept the identification either. Galvani thought that his experiments provided just such an argument. (shrink)

We tend to think that a person who is both reasonable and moral can have a good life. What constitutes a life that is not only good but superlative, or even “marvellous” or “holy”? Those who have such lives are called sages, heroes or saints, and their lives can display great integrity as well as integration with a transformative “Spiritual Presence.” Does it follow that saints are perfect people? Is there a common vision that impels them to seek holiness? In (...) a controversial interpretation of mysticism Horne suggests that there is no single formula for the meaning of life and no one story that displays it to us. Mysticism, rather than being just a visionary perception, then becomes a problem-solving process that brings about a creative transformation of the personality at a critical stage in life. He suggests also that saints may be imperfect morally and describes true saints as double-minded: they are serious in a playful way. Mysticism and Vocation illuminates our understanding of saintly lives by explicating their mystical characteristics and extending discussions of mysticism to explain its role in active lives. In discussing important decisions that go beyond conventional morality, it adds to recent philosophical arguments by Charles Taylor, Alasdair MacIntyre, Iris Murdoch, Bernard Williams and others to the effect that morality should be defined more broadly to deal with the human condition. This book will be of interest to students of philosophy and religious studies, in both graduate and undergraduate programs. (shrink)

p166 In February 1965, the United States escalated the war against South Vietnam radically, and also, on the side, began regular bombing of the North at a much lower level. That was a big public issue in the United States: Should we bomb North Vietnam? The bombing of the South was ignored. The same shows up in the internal planning, for which we now have an extremely rich record, not only from the Pentagon Papers, but from tons of declassified documents (...) that have been released in the last couple of years. It turns out again, one of the very few interesting revelations of the Pentagon Papers that there was no planning for the escalated bombing of the South. There was very meticulous planning about the bombing of the North carefully calibrated, when should we do it, and a lot of agonizing about it. The bombing of the South at triple the scale of the North is barely discussed. There are a few casual decisions here and there. The same shows up in McNamara's recent memoirs. He discusses at great length the bombing of the North. The bombing of the South he literally doesn't mention. He mentions what he did on January 21, 1965, a really important day: there was a big discussion about whether to bomb North Vietnam. He doesn't mention what we know from other documents, that on that same day, he authorized for the first time the use of jet planes to escalate the bombing of South Vietnam over and above the massive bombing that had been going on for years that's not even mentioned.

Mysticism is condemned as often as it is praised. Much of the condemnation comes from mysticism’s apparent disregard of morality and ethics. For mystics, the experience of “union” transcends all moral concern. In this careful examination of the works of such practitioners or examiners of mysticism as Paul Tillich, Thomas Merton, Evelyn Underhill, and Martin Buber, the author posits a spectrum of uneasy relationships between mysticism and morality. Horne explores the polarities of apophatic (imageless) and imaginative mysticism, the contemplative and (...) the active life, and morality and amorality. He stresses the importance of the distinction between “proper-name” (entirely personal) morality and “social” morality, for the history of Christian mysticism is a mix of minimal moral concern, proper-name morality, and social morality. The volume will be of interest to students of religious experience, ethics, and the recent history of mysticism. Carefully reasoned and documented, the argument is couched in clear prose, easily accessible to lay readers as well as to scholars. (shrink)

We argue that the inference of CP violation in experiments involving the K0-K0 system in weak interactions of particle physics is facilitated by the assumption of particle trajectories for the decaying particles and the decay products. A consistent explanation in terms of such trajectories is naturally incorporated within the Bohmian interpretation of quantum mechanics.

Discussions on the nature of reality between Albert Einstein and Rabindranath Tagore, Bengali poet, philosopher and Nobel laureate, have provoked interest among both physicists and philosophers since their first publication in 1930/31. This article points out their relevance to past and present debates about the meaning of quantum mechanics.

This volume offers a comprehensive survey of the main periods, schools, and individual proponents of scepticism in the ancient Greek and Roman world. The contributors examine the major developments chronologically and historically, ranging from the early antecedents of scepticism to the Pyrrhonist tradition. They address the central philosophical and interpretive problems surrounding the sceptics' ideas on subjects including belief, action, and ethics. Finally, they explore the effects which these forms of scepticism had beyond the ancient period, and the ways in (...) which ancient scepticism differs from scepticism as it has been understood since Descartes. The volume will serve as an accessible and wide-ranging introduction to the subject for non-specialists, while also offering considerable depth and detail for more advanced readers. (shrink)

Henry Home (1696-1782) has been called "perhaps the most complete 'Enlightenment man' among the eighteenth-century Scottish thinkers." Kinsman and friend of David Hume, mentor and patron of Adam Smith, John Millar, and Thomas Reid, he was a key figure in that circle of luminaries. He read law, was called to the bar in 1723, was raised to the Bench of the Court of Session in 1752, with the title Lord Kames (the name of his family estate), and joined the (...) High Court of the Justiciary in 1763. Publishing broadly in law, history, philosophy, and criticism, Kames made significant contributions to the Enlightenment's science of human nature. The Essays is commonly considered Kames's most important philosophical work. In the first part, he sets forth the principles and foundations of morality and justice, attacking Hume's moral skepticism and addressing the controversial issue of the freedom of human will. In the second part, Kames focuses on questions of metaphysics and epistemology to offer a natural theology in which the authority of the external senses is an important basis for belief in the Deity. The text of this volume is based on the third edition of 1779, while the appendix presents substantial variant readings in the first and second editions. (shrink)

SummaryLeonhard Euler was the leading eighteenth-century critic of Isaac Newton's projectile theory of light. Euler's main criticisms of Newton's views are surveyed, and also his alternative account according to which light is a wave motion propagated through the aether. Important changes are identified as having occurred between 1744 and 1746 in Euler's thinking about the way in which a wave such as he supposed light to be is propagated through a medium. Paradoxically, in view of Euler's overtly anti-Newtonian stand, these (...) amount to Euler abandoning his early, Malebranchian notions about the physical basis of wave propagation, in favour of the ideas set out by Newton in Book II of his Principia.

We argue that the Aharonov-Anandan-Vaidman model, by using the notion of so-called “protective measurements,” cannot claim to have dispensed with the ldcollapse of the wave function,” because it does not succeed in avoiding the quantum measurement problem. Its claim to be able to distinguish between two nonorthogonal states is also critically examined.

In 1914, the physics discipline had reached a very similar stage of development in Australia and Japan. A generation later the paths of development had considerably diverged. A systematic comparison of the evolution of physics in the two countries during these years identifies factors—political, economic and cultural—that led to this divergence, but it also uncovers a number of underlying parallels.

Many of us have a prereflective sense--or at least, a hope--that there are reasons to be moral which apply to an agent regardless of what his or her existing motivations may be. The view that there are no such reasons may, then, be regarded as a form of moral scepticism. The philosophical position which seems most fit to refute this form of moral scepticism, and hence to support our prereflective sense, is a Kantian view of morality, according to which we (...) are required to be moral solely in virtue of being rational. I examine a number of recent arguments for this position; I conclude that all of them fail, and for similar reasons. Nor, I argue, is there any non-Kantian view which could succeed at the same task. It is thus very tempting to infer that this form of moral scepticism is immune to any simple refutation. However, perhaps the best way to combat scepticism is not to argue for its negation--as do the positions examined so far--but to show that there is something problematic in the sceptic's whole approach to the issue. At this point I turn for enlightenment to an analogy with epistemological scepticism. Here, too, if we try to argue for the negation of scepticism, we seem bound to fail; but here the more subtle strategy of attacking the sceptic's whole approach has actually been attempted. I sketch a number of versions of this more subtle strategy; I then sketch some analogous responses to moral scepticism, and consider whether any of them are successful. I argue that the attempt fails--that even if epistemological scepticism is indeed amenable to this kind of treatment , moral scepticism is not. This conclusion is only strengthened when I argue that another, related strategy, which employs an analogy between morality and mathematics, also falls short at the same point. Moral scepticism therefore survives intact. The appropriate reaction, I suggest, is neither complete despair nor complete equanimity. (shrink)

We review the present status of wave-particle duality of single-photon states in the context of some recent experiments. In particular, Bohr's complementarity principle is critically reexamined. It is explained in detail how this principle is confronted in these experiments and how a contradiction with the notion of “mutual exclusiveness” of classical wave and particle pictures emerges.

Physics first became established in Australia and Japan at the same period, during the final quarter of the nineteenth and the first years of the twentieth century. A comparison of the processes by which this happened in these two developing countries on the Pacific rim shows that, despite the great cultural differences that existed, and that might have been expected to have been a source of major differences in national receptiveness to the new science, there were in fact many parallels (...) between the patterns of development in the two cases. Identifying these enables us to draw attention to a number of significant features of the physics discipline more generally at this period. Such differences as emerge in the early history of physics in the two countries seem to have arisen more from the different political situations that prevailed than from anything else; in particular they reflect the fact that Australia was a part of the British Empire while Japan was an independent political power.

In this article we attempt to bring out some significant general aspects of what we call collapse-induced quantum nonlocal effects resulting from the use of the hypothesis of wave function collapse.

Richard Bett presents a ground-breaking study of Pyrrho of Elis, who lived in the late fourth and early third centuries BC and is the supposed originator of Greek scepticism. In the absence of surviving works by Pyrrho, scholars have tended to treat his thought as essentially the same as the long subsequent sceptical tradition which styled itself 'Pyrrhonism'. Bett argues, on the contrary, that Pyrrho's philosophy was significantly different from this later tradition, and offers the first detailed account of that (...) philosophy in this light. Bett considers why Pyrrho was adopted as the figurehead for that tradition: his answer suggests that we should distinguish two phases within Pyrrhonism, of which the initial phase is much closer to Pyrrho's own thought than is the better-known later phase. Bett also investigates the origins and antecedents of Pyrrho's ideas; in particular, Plato is singled out as an important inspiration. The result is the first comprehensive picture of this key figure in the development of philosophy. The new claims that Bett puts forward have major implications for the history and interpretation of ancient Greek thought. (shrink)

A number of papers on wave-particle duality has appeared since the two-prism experiment was performed by Mizobuchi and Ohtake, based on a suggestion by Ghose, Home, and Agarwal. Against this backdrop, the present paper provides further clarification of the key issues involved in the analysis of the two-prism experiment. In the process, we present an overview of wave-particle duality vis-a vis Bohr's complementarity principle.

In markets where vegetables are commonly cultivated with heavy use of synthetic pesticides, it is particularly important for consumers to be able to identify genuine organic produce. Organic Participatory Guarantee Systems (PGS) certification offers smallholder farmers an affordable way to build trust among consumers and secure premium prices for their organic produce. In Vietnam, the demand for vegetables with no, or low, pesticide residues is growing. The attractiveness of PGS certification should increase accordingly, but the number of organic PGS certified (...) farmers in Vietnam are stagnating or even decreasing. The aim of this study is to explain this paradox by investigating the factors that influence the adoption of organic PGS certification among Vietnamese vegetable farmers. We follow a mixed methods approach, combining a qualitative analysis of farmer interviews (_n_ = 62) and a quantitative analysis of a farm survey data (_n_ = 434) using a sample selection model that estimates adoption contingent on farmers’ awareness of PGS certification. Drawing on the Unified Theory of Acceptance and Use of Technology, we found that social relationships and positive attitudes towards farming and the environment drive the adoption of organic PGS. Barriers include insufficient knowledge of organic farming techniques, labour shortages, and ageing farmers. At the systemic level, support by (non-)governmental institutions facilitates adoption, but challenges such as lower yields and limited access to premium markets remain. To promote organic PGS among Vietnamese vegetable farmers, efforts should focus on disseminating organic farming techniques that boost yields, alleviate labour demands, and ensure secure markets for premium-priced organic vegetables.
