This article arises from the remarkably multi-faceted book Brain and Being edited by Gordon Globus and others, hereafter referred to as B&B. It raises questions (though not unusually, few answers) about several related areas: the way in which quantum theory might endow the physical matter of the brain with surprising, though still essentially classical, properties; the possibility that quantum field theory might shed a wholly new light on aspects of consciousness, in both the subjective and neurological approaches; and, at the most speculative, the suggestion that the nature of being, as disclosed subjectively, can be understood in the light of one or other of the interpretations of quantum theory. I will consider these in turn.

The purpose of this review article is to attempt to come to grips with the elusive vision of Gordon Globus, especially as revealed in this, his latest book. However, one can only grip that which is tangible and solid and Globus’s marriage of Heideggerian anti-concepts and “quantum neurophilosophy” seems purposefully to evade solidity or grasp. This slippery anti-metaphysics is sometimes a curse for the reader seeking imagistic or conceptual clarity, but, on the other hand, it is also the blessing that allows Globus to go far beyond (or deep within) the usual narrative explanations at the frontiers of physics, even that of the quantum variety.

When I look at the scale of the apparatus I know what it reads. Those absurdly delicate, hopelessly inaccessible, global correlations obviously vanish when they connect up with me. Whether this is because consciousness is beyond the range of phenomena that quantum mechanics is capable of dealing with, or because it has infinitely many degrees of freedom or special super selection rules of its own, I would not presume to guess. But this is a puzzle about consciousness that should not get mixed up with efforts to understand quantum mechanics as a theory of subsystem correlations in the nonconscious world. ( David Mermin 1998).

We show that consciousness may violate the basic quantum principle, according to which the nonorthogonal quantum states can't be distinguished. This implies that the physical world is not causally closed without consciousness, and consciousness is a fundamental property of matter, thus provides a possible quantum basis for panpsychism.

There have been suggestions that the unity of consciousness may be related to the kind of holism depicted only in quantum physics. This argument will be clarified and strengthened. It requires the brain to contain a quantum system with the right properties — a Bose-Einstein condensate. It probably does contain one such system, as both theory and experiment have indicated. In fact, we cannot pay full attention to a quantum whole and its parts simultaneously, though we may oscillate between the two. In a quantum theory of consciousness, emergent meanings arise as an inevitable consequence of Heisenberg''s Uncertainty Principle.

Quantum approaches to consciousness are sometimes said to be motivated simply by the idea that quantum theory is a mystery and consciousness is a mystery, so perhaps the two are related. That opinion betrays a profound misunderstanding of the nature of quantum mechanics, which consists fundamentally of a pragmatic scientific solution to the problem of the connection between mind and matter.

We show that consciousness may violate the basic quantum principle, according to which the nonorthogonal quantum states can't be distinguished. This implies that the physical world is not causally closed without consciousness, and consciousness is a fundamental property of matter.

It has been widely thought that consciousness has no causal efficacy in the physical world. However, this may be not the case. In this paper, we show that a conscious being can distinguish definite perceptions and their quantum superpositions, while a physical measuring system without consciousness cannot distinguish such nonorthogonal quantum states. The possible existence of this distinct quantum physical effect of consciousness may have interesting implications for the science of consciousness. In particular, it suggests that consciousness is not emergent but a fundamental feature of the universe. This may provide a possible quantum basis for panpsychism.
