At his blog recently, Cornelius Hunter called attention to this statement of Charles Darwin’s from the Origin of Species:
If it could be demonstrated that any complex organ existed, which could not possibly have been formed by numerous, successive, slight modifications, my theory would absolutely break down. But I can find out no such case.
Cornelius Hunter flags Charles Darwin’s use of the phrase could not possibly to make the following observation about his rhetoric:
Darwin was requiring that the skeptic prove that such structures “could not possibly” have evolved. . . . Darwin was not looking for examples that show evolution to be unlikely. He did not say “did not likely” evolve. He said “could not possibly” evolve. Darwin was erecting high walls around his idea.
