David Bohm's Hidden Variables Interpretation of Quantum Mechanics

Abstract Nowadays, David Bohm’s hidden variables interpretation of quantum mechanics is one among other possible interpretations of quantum mechanics. In 1952 when he published this interpretation, he could not foresee the complex denouement it would have. I argue that the initial poor reception of Bohm’s proposal, as well as his discouragement in the late 1950s, was related to the prejudices among physicists concerning the hidden variables issues, and its later revival, in the mid-1970s, without any new evidence corroborating it, was related to a new intellectual ambiance concerning interpretational issues. However, even today, there is a persistent misunderstanding about what interpretations may be compatible with quantum mechanics. Lessons from this history for the practice of science are related to the role played by prejudices even in advanced fields of scientific research and the need to overcome them.

One of the most important interpretative problems of quantum mechanics concerns the so called hidden variables. Sometimes it is said that the Bell's theorem falsifies theories of such variables, but in fact, it falsifies only local ones. This paper deals with David Bohm's interpretation of quantum mechanics, which is a kind of nonlocal hidden variable theory. This theory delivers a full deterministic and realistic description of quantum phenomena and predicts the same results as standard quantum mechanics. It is argued that this interpretation is still worth being investigated, because it remains in the full agreement with the mathematical formalism of this theory and it surpasses the standard interpretation as far as simplicity and lack of arbitrary assumptions are concerned.

David Bohm is famous for inventing a ‘hidden variables’ interpretation of quantum mechanics, in which particles possess definite positions and momenta, but nonetheless preserve distinctively quantum phenomena perfectly in line with orthodox quantum mechanics. Bohm achieved this by interpreting the quantum wave function as a kind of universal ‘guidance wave’. But his particulate model does not represent the lesson which Bohm thought quantum mechanics was trying to teach us. Bohm had a much more radical metaphysical vision in which the world was, in some difficult to understand sense, an undivided whole. In this paper, I explore a compelling confluence of thought between William James and David Bohm. Arriving from very different starting points and proceeding in very different ways, they share a vision of a unitary world, undivided and ‘beyond’ all the categories of thought and perception. This vision is intrinsically interesting, not least because of the light it shines on the problem of consciousness. It both addresses and presents an entirely novel solution to the famous ‘hard problem of consciousness’.
