Thanks for your comments. Mission accomplished. The objective was to write something that was "fun to read" Some responses.
1. I understand Metaphysics to be the study of existence / existents. I recognise two basic forms of existence: the abstract / mental / platoist; and the physical / materialistic / experiential. We study the first form of Metaphysics rationally; the second form of Metaphysics we encounter reasonably - vide my essay. Naively I regard any thing that we can experience as really existing and part of the second form of Metaphysics. I call it Naive Realism. It is the reasonable part of Metaphysics.
It seems to me that your type of Metaphysics is inchoate (and has been for 2500 years), and leads to much of the confusion I encounter in philosophic works. Philosphers, like physicists and mathematicians, need to do better. However, this is not necessarily a philosophic problem; more a linguistic one - syntactical not semantic.
2. I am not sure what you regard as my premise. My implicit reasonable premise in the context of this competition is that any advocacy of "Naive Realism" is inviting rejection from professional physicists, mathematicians, and most philosophers. Other scientists deal with it daily so may be more receptive. It also invites rejection from crazy amateurs with their latest greatest theory that without any empirical support solves all the problems of phsyics, even all of science. Some individuals manage to be both professional and crazy. The worst of these are essays containing lots of fashionable words and phrases but are devoid of other than mystical content. One essay of 9 pages has 3 pages of wordy "Conclusions" but no conclusion.
The anticipated emotional rejection shows up in the evaluations of my essay - which in the context of this competition is unquestionably a first class essay. Half (more than expected) of my ratings are very high and i get corresponding complimentary comments. Half are extremely low - but NO comments. Not one refutation of any of my 10 points. Very interesting but predictable from a psychological and sociological perspective.
There was no expectation that the FQXI community of professional physicists would welcome Naive Realism at all. Why should they ? It is largely irrelevant for them. Hence no such premise. I think you are mistaking some stylistic flourishes of the essay for premises. The only explicit rational premise was that everyone I know, except me, normally confuses the Rational & the Reasonable - even, as i noted, the OED ! Hence the title, which is were the premise always should be.
