Quantum Approaches to Consciousness
1. Introduction The problem of how mind and matter are related to each other has many facets, and it can be approached from many different starting points. Of course, the historically leading disciplines in this respect are philosophy and psychology, which were later joined by behavioral science, cognitive science and neuroscience. As regards the issue of complexity, this is quite evident: the brain is one of the most complex systems we know. The original motivation in the early 20th century for relating quantum theory to consciousness was essentially philosophical. Quantum theory introduced an element of randomness standing out against the previous deterministic worldview, in which randomness, if it occurred at all, simply indicated our ignorance of a more detailed description (as in statistical physics). Other features of quantum theory, which were found attractive in discussing issues of consciousness, were the concepts of complementarity and entanglement. 2. [ma] [me] 3. 4. 5.
