Crazy: But... he didn't! Well, okay, he did, and for that he should be lauded. But the experiments that he did, which would have established, almost incontrovertibly, viruses/viral transmission... failed! This is really the issue.

Look: I literally remember exactly where I was when I heard about the 'no virus' hypothesis. I thought it was crazy. And then... it just turns out that no experiments ever have demonstrated viral transmission of disease.

I don't think of Ivanovsky (the tobacco-virus guy) as intellectually bankrupt. It's the people ((())) who ran with his work without verifying basic details who are... well, enemies of humanity.
