Highly technical philosophical arguments of the sort many philosophers favor are absent here. That is because I have a prior problem to deal with. I have learned that arguments, no matter how watertight, often fall on deaf ears. I am myself the author of arguments that I consider rigorous and unanswerable but that are often not such much rebutted or even dismissed as simply ignored.
