Typical German in what respect? I mean he spoke German, so I guess that's pretty typical for a German. In other respects, obviously he was not so typical!! (btw, in case you wondered, I also don't regard Plato as a typical-in-all-respects Greek -- as if there were such a thing!)

I take it you think I have implied that Germans have higher than average IQ and that that is false? I don't know if they do, but I didn't mean to imply that, although I do think it's possible. Do you have concrete information to address the question (which is in any case beside the point)?
