Over at Cryptomundo, Loren Coleman has an excellent new post on the whole controversy surrounding whether some crypto-creatures may be Tulpas/thought-forms. Loren is right when he says that much of my inspiration on this matter did indeed come from his earlier writings on this matter; such as that contained within Creatures of the Outer Edge (co-written with Jerome Clark).
I was (I think) about 13 when I first read Edge, and it was a book that both fascinated and intrigued me in equal measures and made me look at much of cryptozoology in a whole new light.
And although many of Loren's views on the Tulpa angle have changed and been discarded over the years, it says much about the man that the two of us can hang-out at conferences, agree to differ on some things (but agree on quite a lot too!), but at the end of the day still remain friends.
