Well, just read the Rawlingson article again.
And have to agree with Dundee. It is a collection of name droppings. He drags every pseudo scientific phrase he can fit in onto the page. Included is the 'if I can't see the Moon, does it exist' argument. also used in a Fleetwood Mac song in the form 'When I hang up the phone do you cease to exist'.
Basically he is saying that ufo only exist if someone is there to see them. So if one passed by and no one picked it up visually or on Radar then it can't have exixsted because no one brought it into reality.
All in all, rather badly assembled new-age twaddle.
At the beginning he mentions the human nervous system. He fails to mention that the nervous system id just a conduit for signals to be sent to and from the brain, which does all the processing.
He seems to miss out the fact that UFO refers to objects. And the objects are, as far as we can tell, physical. The actual phenomena nay indeed contain some non physical aspects. But not in the way Rawlingson suggests.
