“In the right circumstances, a man can help himself by writing a book about his point, or a pamphlet, or at least a letter to the editor, thereby putting his protest on the historical record, which is marvelously comforting even if nobody reads it. Usually, however, it can be counted on to attract the attention of a few readers who assure the author that he is a new Copernicus, whereupon they introduce themselves as unrecognized Newtons. This custom of picking points out of each other's fur is widespread and a great comfort, but it is without lasting effect because the participants soon fall to quarreling and find themselves isolated again.”
