In John Grahm-Cumming's post title Double-checking Dawkins, John double-checked one sentence written by Richard Dawkins in The Blind Watchmaker. After some research, John found out that in 1986 when Richard was busy writing the book on an Apple ][, Richard has actually spent time to poke around inside his computer's ROM.
This is a respect well-deserved. If Richard has been so careful to make sure a minor fact in his book is correct, I have faith that the rest of the facts would have been more than double-checked. My salute to Richard Dawkins!
