I favour the ETH as the most likely of the paranormal theories - but, unlike Stan and many of his colleagues, I understand that it is just a theory, and I don't assert it as a fact. As a result, I keep an open mind about the other theories on offer - because no matter how much someone like Jerry Clark might try to dismiss Jacques Vallee, or J. Allen Hynek, I don't, because, unlike Clark, imprisoned as he is in his need to be accepted by "science", they understood that the UFO phenomenon was a mystery - perhaps even one that our science could not solve.
And that's what really bothers them - they are unable to face the prospect that there is something "out there" that is far beyond our comprehension, that might resemble "religion", at least in terms of our relationship to it, because they are avowed secularists, and any hint of something "divine", whatever the manifestation, is beyond their self-imposed intellectual walls. To them, it simply has to be nuts and bolts craft from another world that behave pretty much exactly like we do, because that's what they need it to be.
As a result, they are unable to say, without equivocation, that "we just don't know", which runs against everything my dad taught me about the nature of true wisdom.
In their failure to grasp this, to admit it, they forget that the science they claim to adhere to is a method, not an end in and of itself.
Of course, cryptos, or extradimensional beings, or whatever, hardly fit the traditional concept of God, although they might fit the ancient concept of "the gods" (you know, like Thor, Loki, Odin, Zeus, Appollo and Aphrodite). But that doesn't matter, and it isn't the point, because I'm not saying that UFOs are a manifestation of the divine (that's Barry Downing's beat, not mine). The point is that anything which calls into question the ETH as ETFact threatens a certain "ufological orthodoxy", in the same way that the protestant Reformation threatened the Catholic othodoxy hundreds of years ago, or Henry Alline threatened the Calvinist orthodoxy in Atlantic Canada in the late 18th century, to the point where his enemies referred to him as "the ravager of churches".
Today, where the UFO phenomenon is concerned, the "Church" is the dogmatic acceptance of the ETH - and the ravagers are guys like Mac Tonnies, and Nick Redfern, and Greg Bishop. Does that mean they're right? No - but then, unlike the die-hard ETHers, they don't claim to be right, or to have all the answers. They don't dismiss guys like Mack, or Vallee, or Hynek, as "New Agey" types, or "apologist ufologists", because they understand that we're still at the stage of asking the questions.
The journey of discovery isn't over - it hasn't even really begun.
