When I read this Letters at 3 a.m. column by Michael Ventura, my reaction was, roughly, “YES! YES! YES! He gets it!”
Not that the fact that he gets it is a surprise, but the way he uses his mind as a precision tool is always such a delight.
Science is based in metaphysics. There is nothing else for it to be based in! But members of what John Anthony West calls The Church of Progress refuse to see it. Too bad. It’s true regardless.

LETTERS AT 3AM –
GREATER AND LESSER UNCONFORMITIES
Austin Chronicle – May 23, 2008
Ever hear of the Great Unconformity? It has much to teach, but it teaches by absence – or by the absence it signifies. There are only two places in North America where the Great Unconformity is visible: Frenchman’s Mountain, overlooking Las Vegas, and the Grand Canyon. At Frenchman’s Mountain, it’s just a seam on a rock face. Hold your thumb sideways and place it on that seam and you touch something that represents 1.2 billion years of unrecorded time. According to Wikipedia, “the rock jumps from 500 million years old to 1.7 billion years old… missing… about 25% of the earth’s history.” The Lunar and Planetary Institute (www.lpi.usra.edu) notes that the Great Unconformity is found “nearly everywhere across the globe”; “it divides rocks with familiar fossils from those with no fossils or only fossil bacteria” – that is, there is little or no fossil record of the early development and evolution of complex organisms. The record stops 1.7 billion years ago and resumes 500 million years ago, by which time life on earth had gotten pretty complex, with all sorts of flora and critters.
