Sorry, I guess I'm still mired in the recent syrup. Besides, you do it better. Thanks for the terser improvement. Now I'll go and see if I still have a copy of Voltaire's Bastards which also exposes some of the above attitude for what it is better than I could and helps me sleep well.
(Another great book I remember is "How Does a Poem Mean?" written by a poor poet but a better student of poems than I am of relations. Like poems, math is something we apply to order our thinking, not someting our thinking is ordered by. I suppose some misguided CS professor in need of a summer grant will someday coin the title "how does a string mean?" but will probably not notice the infinity of relations inherent in the good ones. Like the ones recently mentioned here who thought it important to state the limits of stupidity. All I can say in my defence is that I will probably not download or buy it.)
