“I believe that the problem of quantum measurement should be faced and solved well before we can expect to make any real headway with the issue of consciousness in terms of physical action-and that the measurement problem must be solved in entirely physical terms. Once we are in possession of a satisfactory solution, then we may be in a better position to move towards some kind of answer to the question of consciousness. It is my view that solving the quantum measurement problem is a prerequisite for an understanding of mind and not at all that they are the same problem. The problem of mind is a much more difficult problem than the measurement problem!”
