“ It is hard for a writer to call an editor great, because it is natural for him to think of the editor as a writer manqué. It is like asking a thief to approve a fence, or a fighter to speak highly of a manager. “Fighters are sincere,” a fellow with the old pug’s syndrome said to me at a bar once as head wobbled and the hand that held his shot glass shook. “Managers are pimps, they sell our blood.” In the newspaper trade, confirmed reporters think confirmed editors are mediocrities who took the easy way out. These attitudes mark an excess of vanity coupled with a lack of imagination; it never occurs to a writer that anybody could have wanted to be anything else. ”
