In a very real sense, therefore, advocacy of the doctrine of continuity [i.e evolutionism] has always necessitated on retreat from pure empiricism [i.e., logic an observation], and contrary to what is widely assumed by evolutionary biologists today, it has always been the anti-evolutionists [i.e creationist], not the evolutionists, in the scientific community who have struck rigidly to the facts and adhered to a more strictly empirical approach... It was Darwin the evolutionist who was retreating from the facts.
