Let's not fall victim to the "Argument Against the Man" (er, Person, nowadays).

In this instance the information that Herc appears to be clinically insane is salient. Recall the nature of lwalker's valiant quest. He wants to vindicate people who get called (mathematical) cranks by other people by finding theories in which their unorthodox claims are provable. This sort of vindication obviously can work only if these theories have some actual connection to the thinking of the getting-called-a-crank sort of person in question. And as lwalke admits, it's possible these people are, in fact, just wrong about standard stuff, sometimes they simply don't like the mathematical facts, sometimes they are utter nutters, and so on, in which case the search for an appropriate vindicating theory is futile or irrelevant. -- Aatu Koskensilta (aatu.koskensilta(a)uta.fi) "Wovon man nicht sprechan kann, dar�ber muss man schweigen" - Ludwig Wittgenstein, Tractatus Logico-Philosophicus

I suppose that even a total and actual nutter could be accidentally right once in a long, long while. Though, of course, one would be foolish to count on it.
