I was reading Dorothy Sayers' book, "The Lost Tools of Learning" this evening and came across this:
Well, we may all talk nonsense in a moment of inattention. It is more alarming when we find a well-known biologist writing in a weekly paper to the effect that: “It is an argument against the existence of a Creator that the same kind of variations which are produced by natural selection can be produced at will by stock-breeders.” One might feel tempted to say that it is rather an argument for the existence of a Creator. Actually, of course, it is neither: all it proves is that the same material causes (re-combination of the chromosomes by cross-breeding and so forth) are sufficient to account for all observed variations—just as the various combinations of the same 13 semitones are materially sufficient to account for Beethoven’s Moonlight Sonata and the noise the cat makes by walking on the keys. But the cat’s performance neither proves nor disproves the existence of Beethoven; and all that is proved by the biologist’s argument is that he was unable to distinguish between a material and a final cause.
