Classical logic means determinism, and if you believe in determinism, you have to believe it all the way.  What we end up with is a remarkable view, where problems such as the "measurement problem", the "collapse of the wave function", and the mystery of "Schroedinger's cat" are completely resolved, but not yet many investigators are prepared to pay the price...
