I'd agree with that, though what I've read about him suggests he ticks the right boxes on the Hare Pschopathy checklist:
"Two years later, von Däniken was convicted for "repeated and sustained" embezzlement, fraud and forgery, with the court ruling that the writer had been living a "playboy" lifestyle. Von Däniken entered a plea for nullity on the grounds that his intentions were not malicious and the credit institutions were at fault for failing to adequately research his references, but a court-appointed psychiatrist considered the defendant to be fully accountable for his actions, and described him as a criminal psychopath."
Whether the psychiatrist is right or not, it's true that von Daniken has been one of a number of writers to push the idea that our history might not necessarily be as cut-and-dried as academics think. And for that, he should be applauded.
I'd certainly like to ask him a few questions...
