William A. Dembski. Cambridge University Press, Cambridge, UK, 1998. Here we go again. To be sure, William A. Dembski's book explicitly talks about evolution in only one section spanning a mere seven pages, and quoting only one evolutionist, Richard Dawkins. Let me briefly explain both claims.
Regularity describes such phenomena as the rising and setting of the sun.
Chance is most simply exemplified by the outcomes of tossing a fair coin. If it is not the former, it must be the latter. This kind of reasoning is, of course, quite trivial, and it was worked out in probability theory well before the appearance of this book. As Dembski himself acknowledges, the statistician Andrei Kolmogorov had all the pieces of the puzzle in place by 1965. But never mind that.
