Immanuel Velikovsky’s name is, for many, synonymous with paleobabble. I can think of a few other candidates I’d move ahead of him for such an honor, but Velikovsky indeed belongs to the “modern classical period” of wacky stuff related to study of the ancient world. You can read his Wikipedia page if you’re unfamiliar with him.
I recently came across this link: “Top Ten Reasons Why Velikovsky is Wrong About Worlds in Collision.” The essay at the link is long, dense, and technical. It’s also got terrible formatting (as in no formatting) so it’s hard on the eyes. I link to it because of the pedigree of its author, Leroy Ellenberger, who describes himself as follows:
This Top Ten list is based on 30 years exposure to Velikovsky’s ideas which includes 8 years as an insider at the Velikovsky journal Kronos (1978 – 1986), confidant to Velikovsky (4/78 – 11/79), invited “Devil’s Advocate” at Aeon (’88 – ’91), and 13 years as a turncoat/critic interacting with Velikovsky’s defenders and/or successors at conferences, in private, and in Usenet (’94 -’96) & list-serve forums.
In other words, he knows Velikovsky’s material really, really well. So all the haters can just email him to defend Velikovsky. And good luck with that.
There’s also a new book on Velikovsky’s ideas (with others): The Pseudoscience Wars: Immanuel Velikovsky and the Birth of the Modern Fringe. I just bought it so I’ll be reading it at some point this year.
