"If a man be, in all the known and tangible relations of life, an honourable and good man, he is entitled to respectful mention; nor does the fact of his being a member of an erring church, or the defender of an erring faith, deprive him of his claim to be treated with decency and courtesy in a book, any more than in private social intercourse. To assail a man's positions with strong arguments is quite a different thing from assailing himself with strong invectives."
