We bring out the fact that the essential new quality implied by the quantum theory is nonlocality; i.e., that a system cannot be analyzed into parts whose basic properties do not depend on the state of the whole system. This is done in terms of the causal interpretation of the quantum theory, proposed by one of us (D.B.) in 2952, involving the introduction of the “quantum potential.” We show that this approach implies a new universal type of description, in which (...) the standard or canonical form is always supersystem-system-subsystem; and this leads to the radically new notion of unbroken wholeness of the entire universe. Finally, we discuss some of the implications of extending these notions to the relativity domain, and in so doing, we indicate a novel concept of time, in terms of which relativity and quantum theory may eventually be brought together.

We briefly review the history of de Broglie's notion of the “double solution” and of the ideas which developed from this. We then go on to an extension of these ideas to the many-body system, and bring out the nonlocality implied in such an extension. Finally, we summarize further developments that have stemmed from de Broglie's suggestions.

An appropriate kind of curved Hilbert space is developed in such a manner that it admits operators of $\mathcal{C}$ - and $\mathfrak{D}$ -differentiation, which are the analogues of the familiar covariant and D-differentiation available in a manifold. These tools are then employed to shed light on the space-time structure of Quantum Mechanics, from the points of view of the Feynman ‘path integral’ and of canonical quantisation. (The latter contains, as a special case, quantisation in arbitrary curvilinear coordinates when space is (...) flat.) The influence of curvature is emphasised throughout, with an illustration provided by the Aharonov-Bohm effect. (shrink)

We discuss Einstein's ideas on the need for a theory that is both objective and local and also his suggestion for realizing such a theory through nonlinear field equations. We go on to analyze the nonlocality implied by the quantum theory, especially in terms of the experiment of Einstein, Podolsky, and Rosen. We then suggest an objective local field model along Einstein's lines, which might explain quantum nonlocality as a coordination of the properties of pulse-like solutions of the nonlinear equations (...) that would represent particles. Finally, we discuss the implications of our model for Bell's inequality. (shrink)

We approach the relationship between classical and quantum theories in a new way, which allows both to be expressed in the same mathematical language, in terms of a matrix algebra in a phase space. This makes clear not only the similarities of the two theories, but also certain essential differences, and lays a foundation for understanding their relationship. We use the Wigner-Moyal transformation as a change of representation in phase space, and we avoid the problem of “negative probabilities” by regarding (...) the solutions of our equations as constants of the motion, rather than as statistical weight factors. We show a close relationship of our work to that of Prigogine and his group. We bring in a new nonnegative probability function, and we propose extensions of the theory to cover thermodynamic processes involving entropy changes, as well as the usual reversible processes.

We discuss the question of the relativistic invariance of a quantum theory based on beables, and we suggest the general outlines of one possible form of such a theory.

To complete our ontological interpretation of quantum theory we have to conclude a treatment of quantum statistical mechanics. The basic concepts in the ontological approach are the particle and the wave function. The density matrix cannot play a fundamental role here. Therefore quantum statistical mechanics will require a further statistical distribution over wave functions in addition to the distribution of particles that have a specified wave function. Ultimately the wave function of the universe will he required, but we show that (...) if the universe in not in thermodynamic equilibrium then it can he treated in terms of weakly interacting large scale constituents that are very nearly independent of each other. In this way we obtain the same results as those of the usual approach within the framework of the ontological interpretation. (shrink)

b /b b i Quantum Implications /i /b is dedicated to David Bohm, his work, and the issues raised by his ideas.

David Bohm, Emeritus Professor of Theoretical Physics at Birkbeck College of the University of London and Fellow of the Royal Society, died of a heart attack on October 29, 1992 at the age of 74. Professor Bohm had been one of the world’s leading authorities on quantum theory and its interpretation for more than four decades. His contributions have been critical to all aspects of the field. He also made seminal contributions to plasma physics. His name appears prominently (...) in the modern physics literature, through the Aharonov- Bohm effect , the Bohm-EPR experiment , the Bohm-Pines collective description of particle interactions (random phase approximation), Bohm diffusion and the Bohm causal interpretation of quantum mechanics, also sometimes called the de Broglie-Bohm pilot wave theory. David Bohm was born in Wilkes-Barre, Pennsylvania on December 20, 1917. A student of J. Robert Oppenheimer, Bohm received his Ph.D. from the University of California at Berkeley in 1943. In 1950 he completed the first of his six books, Quantum Theory, which became the definitive exposition of the orthodox (Copenhagen) interpretation of quantum mechanics. Here Bohm presented his reformulation of the paradox of Einstein, Podolsky, and Rosen. It is this Bohm version of EPR which has provided the basis for the enormous expansion of research on the foundations of quantum theory, focusing on nonlocality and the possible incompleteness of the quantum description (the question of “hidden variables”), which has occurred during the past several decades.

The author beginns with a brief commentary on three philosophically remarcable concepts: F. A. Hayek's concept of endogenous and exogenous orders, D. Bohm's concept of implicative and explicative orders and K. R. Popper's concept of the three worlds. On Hayek he appreciates particularly his emphasizing the endogenous order, on Bohm on the other hand his distinguishing between the explicative and implcative orders. He, however criticises Bohm´s conception for its not offe_ring a possibility of definig the ontic opposition (...) of culture against nature. Popper´s conception of the three worlds he criticises for its mostly gnoseological nature: according to Popper it is the world II, which makes the effect of the world III on the world I possible. Partially following D. Bohm the author sees two orders - an explicative and an implicative ones - in nature as well as in culure. The order embodies not only the intrinsic constitutive processes and the rules of the natural and cutural construology, i. e. the explicative order, but also the external outcome of the ontic creative process with its phenotypic forms, i. e. the explicative order. Additionally to this dualism of orders he argues, that there are two different kinds of evolution - the natural and the cultural ones. His suggestion to recognize two world orders aims at a more proper pihlosophical understanding of the ontic opposition of culture against nature including the determination of the presuppositions of their long-term possible coevolution and compatibility.

We present a general derivation of the Duffin-Kemmer-Petiau (D.K.P) equation on the relativistic phase space proposed by Bohm and Hiley. We consider geometric algebras and the idea of algebraic spinors due to Riesz and Cartan. The generators βμ (p) of the D.K.P algebras are constructed in the standard fashion used to construct Clifford algebras out of bilinear forms. Free D.K.P particles and D.K.P particles in a prescribed external electromagnetic field are analized and general Liouville type equations for these cases (...) are obtained. Choosing particular values for the label p we classify the different types of the D.K.P Liouville operators. (shrink)

The Limits of Thought is a series of penetrating dialogues between the great spiritual leader, J. Krishnamurti and the renowned physicist, David Bohm. The starting point of their engaging exchange is the question: If truth is something different than reality, then what place has action in daily life in relation to truth and reality? We see Bohm and Krishnamurti explore the nature of consciousness and the condition of humanity. These enlightening dialogues address issues of truth, desire awareness, tradition, (...) and love. Limits of Thought is an important book by two very respected and important thinkers. Anyone interested to see how Krishnamurti and Bohm probe some of the most essential questions of our very existence will be drawn to this great work. (shrink)

Alarmed by Three Mile Island, Love Canal, and other disastrous deployments of new technologies, the public is demanding more voice in the decision-making on technology. To make this possible, it is proposed that metatechnology be evolved that will provide a practical technology for the safe, effective, and economical use of technology. A case history of a specific metatechnology is presented. Here the metatechnology enabled a realistic balancing of the benefits of mass screening of women by mammography against the hazards from (...) the X-rays. By showing that the screening of women under 50 was counterproductive, this metatechnology helped to ban such screening in a program involving a quarter of a million women. The strategic mistake in setting up this and other technological programs was that the decisions were made by the technologists. They benefited the technologists but were not beneficial to the women. One of the potentials of metatechnology is that in its fully computerized versions it could be used directly by the public for decision-making on the deployment of technologies. (shrink)

In the present state of philosophy in the English-speaking world, to choose to talk about sense data may seem perverse. What could be more boring for one's audience than to attempt variations on so threadbare a theme? And worse, what could be more unfashionable in the aftermath of Wittgenstein and Austin? My reasons for selecting this unpromising topic are twofold. First, the general theme of this series of lectures is empiricism. And whatever meanings we put upon that ambiguous word, it (...) is clear that as a matter of history the problems of perception have been important problems for nearly all those philosophers who would consider themselves to be empiricists. And however unsatisfactory sense datum theories of perception may now be held to be, such theories have been central to the empiricist tradition. Secondly, it is important not to be too much impressed by the fact that a particular philosophical opinion is fashionable or unfashionable. The former certainly does not guarantee its truth nor the latter its falsity. It has often been remarked that philosophical opinions are very rarely refuted. Instead they fall out of vogue only to return some years later in another guise. It is perhaps time to take another look at the notion of sense data. The most ingenious and persistent attacks on analyses of perception in terms of sense data have been at best indecisive, as Professor Ayer showed in his reply to Austin's Sense and Sensibilia.

Pleidooi voor een metafysische visie op hedendaagse sociale en economische problemen.

We assume that a statute permitting physician assisted death has been passed. We note that the rationale for the passage of such a statute would be respect for individual autonomy, the avoidance of suffering and the possibility of death with dignity. We deal with two moral issues that will arise once such a law is passed. First, we argue that the rationale for passing an assistance in dying law in the first place provides a justification for assisting patients to die (...) who are motivated by altruistic reasons as well as patients who are motivated by reasons of self-interest. Second, we argue that the reasons for passing a physician assisted death law in the first place justify extending the law to cover some nonterminal patients as well as terminal patients. (shrink)
