If you were a scientist trying to discover the structure of DNA when Watson and Crick published their article on the double helix, there was nothing you could do but pick up your marbles and go home. The structure had been discovered; nothing more need be said; and scientists moved on from there.But if you are a music scholar preparing a monograph on Bach and a book on the composer comes out, you are of course interested, but you do not burn your manuscript. You know that no one (including yourself) will ever be able to say the last word about Bach and his music” Garfield.
