Sure it's right here on the page before this one, second paragraph and the start of the third:
Banned From The UFO Collective Google Group
I'll post a more detailed look at his theory on the latest episode of The Paracast regarding the experience anomaly - what happened in our head and can't be proven, and the event anomaly - what left evidence behind and is verifiable as an actual event. One lives only in witness testimony and living memory while the latter can be recorded historically as a provable event.
The definitive source is always the horse's mouth. Here's Clark in part 1/4 easily traceable on YouTube where he outlines his theory quite completely. It's a reasonable discussion. His previous Paracast episodes where it's just him as guest also provide good insight into his own philosophy. As a core difference between him and Keel, Clark would say, yes these people appear to have had an incredible experience whereas Keel would then go on to explain exactly what it was and where it came from, even though there's no proof for that position.
Yes I suppose we could continue to bat around the idea that Keel was right, but I don't know how you go about proving that at all. Are you able to prove mothman's existence, other dimensions, or that what's really behind UFO's are demonic entities from those realms? That's actually more in line with Ray Palmer than with trying to develop some form of inquiry into a subject in a way that can be practically built upon. Even Tonnies identifies his own cryptoterrestrial work is a thought experiment and not facts.
Keel celebrates the possibility of the fantastic and I appreciate that much.
I find his calling card to be ironically about self-deprecation which ultimately culminates in a sad, lonely death, shunning himself from a society, a recluse living in an impoverished manner. I think it's a curious thing to explore which of the paranormal cabal end up in poverty, isolated and often wanting nothing to do with the paranormal ever again, as if they did their best to scratch a false reality into existence but it ultimately did not wash. Perhaps creativity and risk taking only gets us so far in some fields of endeavour?
Of course Keel would say to me, as you do, Poppycock, can't you come up with anything more inventive than that to say?! And while I enjoy my imaginative brain blasts as much as the next Keelian, I'm also critical about professing wry invention as proof of anything more than having a good imagination.
"Intellectual cowardice is only one of the problems of the scientific community. Fort rubbed their noses in the swill generated by their gibberish and illiteracy. It was no secret then and now that academic publications are designed to protect the inept and to conceal ignorance. People with nothing to say, who even lack the ability to say nothing, can hide behind the academic method for a lifetime."
