Was David Bohm a Wave Function Realist?

One of the more radical ideas to have emerged in recent metaphysics of quantum theory is wave function realism, according to which the fundamental spatial framework of the world is one of very many dimensions. At first sight this idea sounds similar to the notion of a multidimensional implicate order the physicist David Bohm proposed on the basis of quantum theory in the 1980s. This paper briefly considers Bohm’s various attempts to provide a realist interpretation of the wave function in order to clarify whether or not Bohm was anticipating and even endorsing wave function realism with his implicate order theory. The underlying question is what quantum theory — and non-locality in particular — is trying to tell us about the more fundamental nature of the physical world.
