Here Roland Omnès offers a clear, up-to-date guide to the conceptual framework of quantum mechanics. In an area that has provoked much philosophical debate, Omnès has achieved high recognition for his Interpretation of Quantum Mechanics (Princeton 1994), a book for specialists. Now the author has transformed his own theory into a short and readable text that enables beginning students and experienced physicists, mathematicians, and philosophers to form a comprehensive picture of the field while learning about the most recent advances. This (...) new book presents a more streamlined version of the Copenhagen interpretation, showing its logical consistency and completeness. The problem of measurement is a major area of inquiry, with the author surveying its history from Planck to Heisenberg before describing the consistent-histories interpretation. He draws upon the most recent research on the decoherence effect (related to the modern resolution of the famous Schrödinger's cat problem) and an exact formulation of the correspondence between quantum and particle physics (implying a derivation of classical determinism from quantum probabilism). Interpretation is organized with the help of a universal and sound language using so-called consistent histories. As a language and a method, it can now be shown to be free of ambiguity and it makes interpretation much clearer and closer to common sense. (shrink)

For nearly two thousand years Buddhism has mystified and captivated both lay people and scholars alike. Seen alternately as a path to spiritual enlightenment, an system of ethical and moral rubrics, a cultural tradition, or simply a graceful philosophy of life, Buddhism has produced impassioned followers the world over. The Buddhist saint Nagarjuna, who lived in South India in approximately the first century CE, is undoubtedly the most important, influential, and widely studied Mahayana Buddhist philosopher. His many works include texts (...) addressed to lay audiences, letters of advice to kings, and a set of penetrating metaphysical and epistemological treatises. His greatest philosophical work, the Mulamadhyamikakarika--read and studied by philosophers in all major Buddhist schools of Tibet, China, Japan, and Korea--is one of the most influential works in the history of Indian philosophy. Now, in The Foundations of the Philosophy of the Middle Way, Jay L. Garfield provides a clear and and eminently readable translation of Nagarjuna's seminal work, offering those with little of no prior knowledge of Buddhist philosophy a view into the profound logic of the Mulamadhyamikakarika. Translated from the Tibetan, the tradition through which Nagarjuna's philosophical influence has largely been transmitted, Garfield presents a superb translation of Mulamadhyamikakarika in its entirety. Illuminating the systematic character of Nagarjuna's reasoning, as well as the works profundity, Garfield shows how Nagarjuna develops his doctrine that all phenomena are empty of inherent existence and essenceless. But, he argues, phenomena nonetheless exist conventionaly, and that indeed conventional existence and ultimate emptiness are in fact the same thing. This represents the radical understanding of the Buddhist doctrine of the two truths, or two levels of reality. Nagarjuna reinterprets all of Buddhist metaphysics and epistemology through this analytical framework--"a systematic and beautifully elegant philosophical dissection of reality." In turn, Garfield goes on to offer the only verse-by-verse commentary based upon the Indo-Tibetan Prasangika-Madhyamika reading of Nagarjuna, the school most influential in the development of Mahayana philosophy in Tibet, China, Korea, and Japan. Written specifically for the Western reader, the commentary explains Nagarjuna's positions and arguments in the language of Western metaphysics and epistemology, and connects Nagarjuna's concerns tho those of Western philosophers such as Sextus, Hume, and Wittgenstein. A fascinating and accessible translation of the foundational text for all Mahayana Buddhism text, The Fundamental Wisdom of the Middle Way will enlighten all those in search of the essence of reality.

In recent years, a ''change in attitude'' in particle physics has led to our understanding current quantum field theories as effective field theories (EFTs). The present paper is concerned with the significance of this EFT approach, especially from the viewpoint of the debate on reductionism in science. In particular, I shall show how EFTs provide a new and interesting case study in current philosophical discussion on reduction, emergence, and inter-level relationships in general.

In a recent article Humphreys has developed an intriguing proposal for making sense of emergence. The crucial notion for this purpose is what he calls "fusion" and his paradigm for it is quantum nonseparability. In what follows, we will develop this position in more detail, and then discuss its ramifications and limitations. Its ramifications are quite radical; its limitations are substantial. An alternative approach to emergence that involves quantum physics is then proposed.

EMERGENT EVOLUTION- THE GIFFORD LECTURES DELIVERED IN THE UNIVERSITY OF ST.

* This paper was to have been written jointly with Don Campbell. His tragic death on May 6, 1996, occurred before we had been able to do much planning for the paper. As a result, this is undoubtedly a very different paper than if Don and I had written it together, and, undoubtedly, not as good a paper. Nevertheless, I believe it maintains at least the spirit of what we had discussed. Clearly, all errors are mine alone.

We survey and clarify some recent appearances of the term ‘emergence’. We distinguish epistemological emergence, which is merely a limitation of descriptive apparatus, from ontological emergence, which should involve causal features of a whole system not reducible to the properties of its parts, thus implying the failure of part/whole reductionism and of mereological supervenience for that system. Are there actually any plausible cases of the latter among the numerous and various mentions of ‘emergence’ in the recent literature? Quantum mechanics seems (...) to offer one, in the Bell properties of entangled particles, but other apparently promising candidates, such as non‐linear dynamical systems investigated by complexity studies and chaos theory, seem on careful analysis to display only epistemological emergence. We examine the consequences for physicalism of admitting ontological emergence in the micro‐physical. (shrink)

How does the conscious mind relate to the physical body? Two common views from the past offered the stark choice between dualism which said mind and body were quite separate and physicalism which said that the mind was in fact 'nothing but' the physical brain. Both these views are now widely rejected. 'Emergence' theory offers a compromise: the mind ‘emerges’ from the physical body but the whole person, mind and body, is more than the sum of the physical parts. In (...) _The Emergence of Consciousness_ philosopher Robert Van Gulick gives a clear and masterly overview and comparison of the current ‘emergent’ and ‘reductive’ approaches. Other contributors discuss more detailed aspects of the subject. The editor's own chapter argues for the radical proposal that even God is an ‘emergent property’. (shrink)

A framework for representing a specific kind of emergent property instance is given. A solution to a generalized version of the exclusion argument is then provided and it is shown that upwards and downwards causation is unproblematical for that kind of emergence. One real example of this kind of emergence is briefly described and the suggestion made that emergence may be more common than current opinions allow.

In recent years, a change in attitude in particle physics has led to our understanding current quantum field theories as effective field theories. The present paper is concerned with the significance of this EFT approach, especially from the viewpoint of the debate on reductionism in science. In particular, it is a purpose of this paper to clarify how EFTs may provide an interesting case-study in current philosophical discussion on reduction, emergence and inter-level relationships in general.

This book is the final outcome of two projects. My first project was to publish a set of texts written by Schrodinger at the beginning of the 1950's for his seminars and lectures at the Dublin Institute for Advanced Studies. These almost completely forgotten texts contained important insights into the interpretation of quantum mechanics, and they provided several ideas which were missing or elusively expressed in SchrOdinger's published papers and books of the same period. However, they were likely to be (...) misinterpreted out of their context. The problem was that current scholarship could not help very much the reader of these writings to figure out their significance. The few available studies about SchrOdinger's interpretation of quantum mechanics are generally excellent, but almost entirely restricted to the initial period 1925-1927. Very little work has been done on Schrodinger's late views on the theory he contributed to create and develop. The generally accepted view is that he never really recovered from his interpretative failure of 1926-1927, and that his late reflections are little more than an expression of his rising nostalgia for the lost ideal of picturing the world, not to say for some favourite traditional picture. But the content and style of Schrodinger's texts of the 1950's do not agree at all with this melancholic appraisal; they rather set the stage for a thorough renewal of accepted representations. In order to elucidate this paradox, I adopted several strategies. (shrink)

When he formulated the program of neurophenomenology, Francisco Varela suggested a balanced methodological dissolution of the hard problem of consciousness. I show that his dissolution is a paradigm which imposes itself onto seemingly opposite views, including materialist approaches. I also point out that Varela's revolutionary epistemological ideas are gaining wider acceptance as a side effect of a recent controversy between hermeneutists and eliminativists. Finally, I emphasize a structural parallel between the science of consciousness and the distinctive features of quantum mechanics. (...) This parallel, together with the former convergences, point towards the common origin of the main puzzles of both quantum mechanics and the philosophy of mind: neglect of the constitutive blindspot of objective knowledge.
