Perception and reality, truth and falsehood, black and white; nowadays the salivating chattering classes don’t know their arse from a hole in the ground, as they used to say in Brooklyn before the yuppies moved in. Take, for example, the latest kerfuffle about the moon landing 49 years ago. I remember it well because it was summer, I had just acquired my first sailing boat —thanks to good old dad, naturally — and the Americans, under the great president Richard Nixon, were going to land and walk on the moon.
