David Bohm's interpretation of quantum mechanics yields a quantum potential, Q. In his early work, the effects of Q are understood in causal terms as acting through a real (quantum) field which pushes particles around. In his later work (with Basil Hiley), the causal understanding of Q appears to have been abandoned. The purpose of this paper is to understand how the use of certain metaphors leads Bohm away from a causal treatment of Q, and to evaluate the use of (...) those metaphors. (shrink)

Formalised knowledge systems, including universities and research institutes, are important for contemporary societies. They are, however, also arguably failing humanity when their impact is measured against the level of progress being made in stimulating the societal changes needed to address challenges like climate change. In this research we used a novel futures-oriented and participatory approach that asked what future envisioned knowledge systems might need to look like and how we might get there. Findings suggest that envisioned future systems will need (...) to be much more collaborative, open, diverse, egalitarian, and able to work with values and systemic issues. They will also need to go beyond producing knowledge about our world to generating wisdom about how to act within it. To get to envisioned systems we will need to rapidly scale methodological innovations, connect innovators, and creatively accelerate learning about working with intractable challenges. We will also need to create new funding schemes, a global knowledge commons, and challenge deeply held assumptions. To genuinely be a creative force in supporting longevity of human and non-human life on our planet, the shift in knowledge systems will probably need to be at the scale of the enlightenment and speed of the scientific and technological revolution accompanying the second World War. This will require bold and strategic action from governments, scientists, civic society and sustained transformational intent. (shrink)

The present paper investigates the philosophical relationship between John von Neumann’s Nohidden-variable theorem and Bell’s inequalities. Bell erroneously takes the axiomatic method as implying a finality claim and thus ignores von Neumann’s strongly pragmatist stance towards mathematical physics. If one considers, however, Hilbert’s axiomatic method as a critical enterprise, Bell’s theorem improves von Neumann’s by defining a more appropriate notion of ‘ hidden variable’ that permits one to include Bohm’s interpretation which recovers the predictive content of quantum mechanics. Contrary to (...) Bell’s belief, accepting this model does not require adopting the metaphysically realist Böhm picture. If one takes the latter as a physical research programme one sees that it only partly disputes a common domain of facts with the mathematically oriented research programme of von Neumann. (shrink)

As far as classical physics is concerned, it is possible to trace causal relations between physical objects back to intrinsic properties of these objects. On this view, causal relations turn out to be internal instead of external relations, supervening on intrinsic properties of the relata. However, one can raise doubts about this view already in Newtonian mechanics. The decisive blow to this view comes from quantum physics, with Bell’s theorem proving that no dynamics based on local, intrinsic properties of quantum (...) objects can yield the empirical predictions of quantum mechanics. Nonetheless, quantum entanglement by no means implies that we have to abandon an ontology of objects in favour of an ontology of structures. Any of the known proposals for a quantum ontology of matter in space-time is committed to objects. However, on any of these proposals, what determines the dynamics of these objects are not local, intrinsic properties, but a global or holistic property instantiated by all the objects together – that is, a structure that takes all the objects in the universe as its relata. The view set out in this paper thus amounts to combining ontic structural realism with an ontology of objects that can be conceived as substances. This suggestion is illustrated by drawing on the ontology of quantum physics worked out by Bohm and Bell. (shrink)

Papers advocating a hidden-variable interpretation of quantum mechanics typically begin by emphasizing that John von Neumann’s no-go theorem does not apply to them. If authors are ontologically minded, their criticism also takes aim at his theory of measurement as expressed in his seminal 1932 book Mathematical Foundations of Quantum Mechanics Additionally, David Bohm and Basil Hiley have recently argued that “in so far as von Neumann effectively gave the quantum state a certain ontological significance, the net result was to produce (...) a confused and unsatisfactory ontology. This ontology is such that the collapse of the wave function must also have an ontological significance.”. (shrink)

In recent literature, it has become clear that quantum physics does not refute Humeanism: Lewis’s thesis of Humean supervenience can be literally true even in the light of quantum entanglement. This point has so far been made with respect to Bohm’s quantum theory. Against this background, this paper seeks to achieve the following four results: to generalize the option of quantum Humeanism from Bohmian mechanics to primitive ontology theories in general; to show that this option applies also to classical mechanics; (...) to establish that it requires a commitment to matter as primitive stuff, but no commitment to natural properties ; to point out that by removing the commitment to properties, the stock metaphysical objections against Humeanism from quidditism and humility no longer apply. In that way, quantum physics strengthens Humeanism instead of refuting it. (shrink)

Eighty years after de Broglie’s, and a little more than half a century after Bohm’s seminal papers, the de Broglie–Bohm theory (a.k.a. Bohmian mechanics), which is presumably the simplest theory which explains the orthodox quantum mechanics formalism, has reached an exemplary state of conceptual clarity and mathematical integrity. No other theory of quantum mechanics comes even close. Yet anyone curious enough to walk this road to quantum mechanics is soon being confused by many misleading signposts that have been put up, (...) and not just by its detractors, but unfortunately enough also by some of its proponents. This paper outlines a road map to help navigate ones way. (shrink)

In lieu of an abstract, here is a brief excerpt of the content:Journal of the History of Philosophy 39.2 (2001) 307-308 [Access article in PDF] Mayer, Paola. Jena Romanticism and Its Appropriation of Jakob Böhme: Theosophy, Hagiography, Literature. McGill-Queen's Studies in the History of Ideas, no. 25. Montreal and Kingston: McGill-Queen's University Press, 1999. Pp. x + 242. Cloth, $65.00. Paolo Mayer sets out to revise the accepted image of the influence of Jakob Böhme, the sixteenth-century mystic and theosophist, on (...) the romantic poets and philosophers who congregated at Jena in the years 1798-1803. She convincingly argues that, except for the philosophers and critics Friedrich Schlegel and F. W. J. Schelling, Böhme's direct influence was negligible, more a matter of the self-proclaimed new religion of romanticism making ideological use of a controversial, in some sense subversive, forerunner in German literary history. In the hands of Ludwig Tieck, for instance, or Novalis, Böhme becomes a symbol of the new religion of Poesie and the hostile reception afforded by the orthodox evangelical pastors of his time becomes an allegory for the hostility that the new, "let it all hang out" aesthetic of romanticism encountered in the more classical and form-loving members of the literary culture. In Mayer's terms, Böhme's reception among the poets was hagiographic; he was the romantics' poster child.Böhme lived from 1575 to 1624. The son of peasants, but by no means unlettered, the "mystic shoemaker of Görlitz" claimed the source of his teachings was direct divine revelation. He claimed to have visions in 1600 and 1610, whose content he translated into his unusually graphic writings, interspersed with Pietist attacks on reason and on outward religious observances. This unusual 'theology' blended themes that F. Schlegel and Schelling, at least, found attractive: (a) the idea of a self-generating or developmental God, (b) an approach to the problem of evil that logically seems to place responsibility on God, and (c) a large systematic role for desire and will, rather than reason, in the origin of the world and in human salvation. Notable also is the physicalism of Böhme's theology, and the assignment of a wrathful nature to God the Father. Böhme's reception in the seventeenth and eighteenth centuries, determined largely by a first biography written in 1652 by a disciple named von Furstenburg, was generally warm in pietist circles, cool in rationalist quarters, e.g., in that of Lessing and Leibniz.The established story is that all the major romantic writers, poets as well as philosophers, were influenced through a direct study of Böhme's texts. Mayer takes issue with that, especially in the case of the poets Tieck and Novalis and the scientists J. W. Ritter. Though each of them writes glowingly of Böhme as a poet—in fact a persecuted poet, a near-martyr for the religion of Poesie—Mayer finds no sound evidence for a direct transmission, either of ideas or of terminology, from Böhme to these figures. What other literary critics have advanced as evidence is, she argues, a body of ideas and vocabulary common to the Neoplatonic, mystic tradition and to Christian thinking in general. If a stricter standard of proving "reception" than mere similarity of language is adopted, it seems that Tieck, Novalis, and Ritter had a slim acquaintance with Böhme's writings, but nonetheless advanced a hagiographic view of the "folk poet." Others among the Jena circle—Schleiermacher, A. W. Schlegel, Dorothea and Caroline Schlegel—took a skeptical view of this propagandistic ploy. Only the more philosophical minds, F. Schlegel and Schelling, read Böhme in any depth or ventured elaborate appropriations. Mayer argues that both these figures went [End Page 307] through an initial phase of enthusiasm for Böhme, to be later followed by personal reservations about him and, eventually, by public criticism from a philosophical or orthodox theological stance. Mayer obviously relishes the irony, in this case, of an initial idolization of Böhme as a representative of the 'new religion... (shrink)

It is commonly believed that the epistemology of mathematics must be different from the epistemology of science because their objects are different in kind, i.e. metaphysically different. In this chapter, I want to suggest that some careful work must be done before we can take the distinction between physical and mathematical objects for granted. This distinction has traditionally been drawn by making reference to location, causal powers, detectability in principle, and change in properties. By analysing the ontology of theoretical physics, (...) I wish to show that some physical objects, like quantum particles as they are described by D. Bohm, are as much mathematical as physical, for they do not seem to be located in space and time, and they are as incomplete as mathematical objects. The upshot of this discussion is to address those who are realists about physical objects and anti‐realists about mathematical objects, and, more importantly, to suggest that mathematical realists should not assume that a realist epistemology should be radically different from ordinary scientific epistemology.

On Two Types of Realism in Quantum Theory. Current realist approaches to the foundations of quantum theory emphasize the dichotomy between (Copenhagen) positivism and ‘beable’-realism. Recently it was even attempted to turn this picture into two (equally possible) histories in order to legitimate Bohmian Mechanics as a viable alternative. This paper argues that this dichotomy is philosophically inadequate and historically questionable by embedding it into the philosophical discussion on positivism and realism that has taken place since the 1920s. Logical Empiricists (...) back then advocated empirical realism and contrasted it to absolutistic metaphysical realism. From this viewpoint David Bohm's ‘beable’-realism combines elements of Mach's sensualism with a pre-Kantian metaphysics. As Wesley Salmon's position shows, empirical realism can become quite pronounced without relapsing into Bohmian philosophy. Instead it arrives close to the GRWP-interpretation. Hence, when Bernard d'Espagnat binds both together as ‘ontological interpretations’, he blurs the borderline between empirical and metaphysical realism that his Veiled Reality has set out to draw, quite in concordance with Logical Empiricism.

A generic non-conservative force, applied to an interferometer particle for a period in the past and then turned off, leaves stationary phase and fringe shifts in the now force-free interferometer. Both Aharonov-Bohm and Aharonov-Casher topological phase and fringe shifts can be created in this way. The specific sources of the non-conservative forces behind Aharonov-Bohm and Aharonov-Casher stationary fringe shifts are, respectively, Faraday induction fields and Maxwell displacement currents, now off.

The discussion of the recently derived quantum Hamilton equations for a spinning particle is extended to spin measurement in a Stern–Gerlach experiment. We show that this theory predicts a continuously changing orientation of the particles magnetic moment over the course of its motion across the Stern–Gerlach apparatus. The final measurement results agree with experiment and with predictions of the Pauli equation. Furthermore, the Einstein–Podolsky–Rosen–Bohm thought experiment is investigated, and the violation of Bells’s inequalities is reproduced within this stochastic mechanics approach. (...) The origin of the violation of Bell’s inequalities is traced to the the non-local nature of the velocity fields for an entangled state in the stochastic formalism, which is a result of a non-separable probability distribution of the considered particles.

The conceptual structure of orthodox quantum mechanics has not provided a fully satisfactory and coherent description of natural phenomena. With particular attention to the measurement problem, we review and investigate two unorthodox formulations. First, there is the model advanced by GRWP, a stochastic modification of the standard Schrödinger dynamics admitting statevector reduction as a real physical process. Second, there is the ontological interpretation of Bohm, a causal reformulation of the usual theory admitting no collapse of the statevector. Within these two (...) seemingly quite different approaches, we discuss in a comparative manner, several points: The meaning of the state vector, the status of quantum probability, the legitimacy of attributing macro objective properties to physical systems, and the possibility of retrieving the classical limit. Finally, we consider aspects of non-locality and relevant difficulties with formulating a relativistic generalization of the two approaches. (shrink)

Models of the EPR-Bohm experiment usually consider just two times, an initial time, and the time of measurement. Within such analyses, it has been argued that locality is equivalent to determinism, given the strict correlations of quantum mechanics. However, an analysis based on such models is only a preliminary to an analysis based on a complete dynamical model. The latter analysis is carried out, and it is shown that, given certain definitions of locality and determinism for completely dynamical models, locality (...) implies, but is not implied by, determinism. Further, it is suggested that a local deterministic model has not been ruled out by Bell's theorem. It is suggested that such a model could naturally deny the independence of initial complete states from the settings of the apparatuses (a crucial assumption in the derivation of Bell's inequality).

David Bohm was one of the foremost scientific thinkers and philosophers of our time. Although deeply influenced by Einstein, he was also, more unusually for a scientist, inspired by mysticism. Indeed, in the 1970s and 1980s he made contact with both J. Krishnamurti and the Dalai Lama whose teachings helped shape his work. In both science and philosophy, Bohm's main concern was with understanding the nature of reality in general and of consciousness in particular. In this classic work he develops (...) a theory of quantum physics which treats the totality of existence as an unbroken whole. Writing clearly and without technical jargon, he makes complex ideas accessible to anyone interested in the nature of reality. (shrink)

In his classic work, _Wholeness and the Implicate Order_, David Bohm develops a theory of quantum physics which treats the totality of existence, including matter and consciousness, as an unbroken whole. David Bohm presents a rational and scientific theory which explains cosmology and the nature of reality; written clearly, and without the use of technical jargon, it is essential reading for those interested in physics, philosophy, psychology and the connection between consciousness and matter. David Bohm was one of the foremost (...) scientific thinkers and distinguished theoretical physicists of his generation. His best-known works include: _Quantum Theory_,_Causality and Chance in Modern Physics_ and _The Undivided Universe_. (shrink)

In the _The Undivided Universe_, David Bohn and Basil Hiley present a radically different approach to quantum theory. They develop an interpretation of quantum mechanics which gives a clear, intuitive understanding of its meaning and in which there is a coherent notion of the reality of the universe without assuming a fundamental role for the human observer. With the aid of new concepts such as active information together with non-locality, they provide a comprehensive account of all the basic features of (...) quantum mechanics, including the relativistic domain and quantum field theory. It is shown that, with the new approach, paradoxical or unsatisfactory features associated with the standard approaches, such as the wave-particle duality and the collapse of the wave function, do not arise. Finally, the authors make new suggestions and indicate some areas in which one may expect quantum theory to break down in a way that will allow for a test. _The Undivided Universe_ is an important book especially because it provides a different overall world view which is neither mechanistic nor reductionist. This view will ultimately have radical implications not only in physics but also in our general approach to all areas of life. (shrink)

David Bohm argues that our fragmented, mechanistic notion of order permeates not only modern science and technology today, but also has profound implications ...

According to the received account of guilt in the philosophical literature, one cannot feel guilt unless one takes oneself to have done something morally wrong. But ordinary people feel guilt in many cases in which they do not take themselves to have done anything morally wrong. In this paper, I focus on one kind of guilt without perceived wrongdoing, guilt about being merely causally responsible for a bad state-of-affairs. I go on to present a novel account of guilt that explains (...) guilt about mere causal responsibility, according to which guilt represents part of the self as bound up with what is bad. (shrink)

The fact that Gilbert Ryle and J.L. Austin seem to disagree about the ordinary use of words such as ‘voluntary’, ‘involuntary’, ‘voluntarily’, and ‘involuntarily’ has been taken to cast doubt on the methods of ordinary language philosophy. As Benson Mates puts the worry, ‘if agreement about usage cannot be reached within so restricted a sample as the class of Oxford Professors of Philosophy, what are the prospects when the sample is enlarged?’ (Mates, Inquiry 1:161–171, 1958, p. 165). In this chapter, (...) we evaluate Mates’s criticism alongside Ryle’s and Austin’s specific claims about the ordinary use of these words, assessing these claims against actual examples of ordinary use drawn from the British National Corpus (BNC). Our evaluation consists in applying a combination of methods: first aggregating judgments about a large set of samples drawn from the corpus, and then using a clustering algorithm to uncover connections between different types of use. In applying these methods, we show where and to what extent Ryle’s and Austin’s accounts of the use of the target terms are accurate as well as where they miss important aspects of ordinary use, and we demonstrate the usefulness of this new combination of methods. At the heart of our approach is a commitment to the idea that systematically looking at actual uses of expressions is an essential component of any approach to ordinary language philosophy. (shrink)

Our aim in this paper is to present the distinct ways in which Wolff, Baumgarten, and Kant understand the relationship between necessitation, constraint, and reluctant action in an effort to illustrate the subtle ways in which their conceptions of obligation differ from each another. Whereas Wolff conceives of natural or moral obligation as incompatible with constraint, Baumgarten holds that constraint and reluctant action are, in some instances, compatible with natural obligation. Kant departs from Baumgarten by conceiving of obligation as necessarily (...) involving constraint: as Kant’s reply to Schiller’s famous objection reveals, obligation must take on the character of constraint to reluctant action on account of the fact that human beings possess inclinations that always threaten to impel them in directions that oppose morality.

What is the relation between small-scale collaborative plans and the execution of those plans within interactive contexts? I argue here that joint attention has a key role in explaining how shared plans and shared intentions are executed in interactive contexts. Within singular action, attention plays the functional role of enabling intentional action to be guided by a prior intention. Within interactive joint action, it is joint attention, I argue, that plays a similar functional role of enabling the agents to act (...) in a collaborative way such that their actions are rationally guided by a prior shared intention. This understanding of joint attention – as having a key functional role of enabling the rational guidance of joint intentional action by a prior shared intention – allows for an alternative understanding of the kind of minimal cooperation that infants can engage in. On this understanding, infants’ capacity to engage in joint actions is already an incipient capacity to engage in rational and intentional joint actions, albeit a capacity that is necessarily scaffolded by an adult rational co-partner.

An Essay on Human Action seeks to provide a comprehensive, detailed, enlightening, and (in its detail) original account of human action. This account presupposes a theory of events as abstract, proposition-like entities, a theory which is given in the first chapter of the book. The core-issues of action-theory are then treated: what acting in general is (a version of the traditional volitional theory is proposed and defended); how actions are to be individuated; how long actions last; what acting intentionally is; (...) what doing one thing by doing another is; what basic action is; and what omitting to do something is. Attention is also given to the concepts of causation, intention, volition, deciding, choosing, and trying. Finally, a libertarian account of free action is tentatively proposed and defended.
