Bohm's Alternative to Quantum Mechanics. Scientific American, May 1994. A relatively non-technical presentation, understandable to the layman. Theories of matter are at the center of a theory of mind. An understanding of these two phenomena may require as radical a shift in our conceptual framework for both matter and mind as the theory of relativity and quantum mechanics did for physics.
Classical physics is based on the proposition that the answer to the question is yes.
Orthodox quantum mechanics is a theory based on the proposition that the answer is no, and that we can only make precise quantitative statements about probabilities, the limitation due to an essential interaction between the observer and that which is being measured. This has consequences for a theory of mind, since in this view the act of conscious observation has a direct effect on the measurement made. The view has been criticized by David Bohm for not providing a coherent ontology of either matter or mind. Referring to the classical Bohr-Einstein debate, Goldstein says the debate has already been resolved in favor of Einstein. Bohmian mechanics is by far the simplest and clearest version of quantum theory.
