I dont know any clinical information, but some (many, in fact) people assume mental illness when someone behaves in such a way that they believe their world view and mental model is absolute and fight to the last tooth and nail against any opposing view points (to the detriment of their own well being and others).
Well then, the founding fathers of the United States were all mentally ill. All of the greatest scientific minds that made breakthroughs in their field are mentally ill.
if one has a scientific mind, they will accept evidence which may be contrary to their personal views. If you dont, you cannot be said to have a scientific mind, let alone greatest.

that may in fact, be the case, but chances are someone today of similar disposition would not be able to do the same.

Sane people adapt themselves to the world. The insane ones persist in trying to adapt the world to themselves. Therefore all progress depends on the mentally abnormal.
(Parody of a famous quote about "unreasonable man".)
"The reasonable man adapts himself to the world: the unreasonable one persists in trying to adapt the world to himself. Therefore all progress depends on the unreasonable man."
