Rosenblum, who himself is a graduate of Yale Law School and the University of Chicago, gave a lucid explanation of how Neo-Darwinism survives:
First step: Exclude all non-natural causes as a priori inadmissible. Second step: If Darwinian Evolution were true, it would explain observed taxonomic similarities between different living things. Third step: Since no alternative explanation exists to explain those phenomena, Darwinism must be true. … Fourth step: Since Darwinism is true, all explanations based on non-natural causes are vanquished. Note how that which was a priori excluded at the outset is now deemed to have been somehow disproved.
(Jonathan Rosenblum, “The Myth of Scientific Objectivity," Jewish Observer (May, 2006).)
Progress in the battle between Darwinism and ID is judged, by both sides, by who has the most Nobel prize winners and National Academy of Science members (they do!), but for me the whole issue has always been extremely simple. It’s not too complicated for the layman to understand, it’s too simple for the scientist.
