I notice that Leslie has received zero support for his assertions thus far. So, if you don't mind Leslie, I'll weigh in on your side. (Warning: many people later regret having me on their side.)
I have a number of notions. I hesitate to call them hypotheses and they are certainly not theories. I have a sound education, rank high in IQ tests (which at least demonstrates an aptitude for IQ tests.) and have several decades of engineering and business experience. I am recognised by my peers as being very logical, objective and a sound critical thinker.
I mention these points not to blow my own trumpet, but as relevant background information. If we accept that this description is accurate would it be reasonable for me to present these notions to experts for their review? My belief is that it would be inappropriate. Although these notions fall within or immediately adjacent to the fields in which I graduated with an honours degree I do not feel, given their radical nature, that it would be appropriate to waste the time of a professional by asking them to review the notions.
It appears as if Carrier, with little if any more grounding than I, is willing to place this imposition on the professionals. Despite his protestations that he expects to be proven wrong it seems to me presumptuous to, nevertheless, trouble the professionals to explain in what way his thinking is mistaken. My own approach is to continue to expand my knowledge and to test my notions against current theory and observation. This seems to me a more sensible and respectful approach.
Leslie, does this broadly reflect your reservations about Carrier's approach, or am I in some remote no-man's land twixt the two "sides"?
