Elsie--if it is any consolation, I also feel pretty strongly about it all. In some other threads I refer to my attempts at writing up my theroies of how to approach all this without having to chisel definitions in stone. Perhaps together we can find a way to say it that will appeal to a larger audience. I will post ideas in here as I think them out. I appreciate a number of thoughts I have read in here. This forum may be the start of somethink really useful!
