----------------- HES POSTING ----------------- Mathew: I know very little about your subject, but I am interested in it. Could you send me some quotes on "instrumental analysis", as you said you could? As far as I know, the Greek "heuristics" is a system of solving problems. It is somehow connected to the ancient sense of the term "dialectics", Socrates building arguments and counter-arguments to plead his innocence. If this is the case, it has also something to do with rhetorics.
