There are metaphysical problems, which cannot be disposed of by declaring them meaningless. For, as I have repeatedly said, they are “beyond physics” indeed and demand an act of faith. We have to accept this fact to be honest. There are two objectionable types of believers: those who believe the incredible and those who believe that “belief” must be discarded and replaced by “the scientific method.”
