Every first-rate editor I have ever heard of reads, edits and rewrites every word that goes into his publication.... Good editors are not 'permissive'; they do not let their colleagues do 'their thing'; they make sure that everybody does the 'paper's thing.' A good, let alone a great editor is an obsessive autocrat with a whim of iron, who rewrites and rewrites, cuts and slashes, until every piece is exactly the way he thinks it should have been done.
