Call up any Wikipedia article about literature—a book or an author or a poem or whatever. Now search on that page for the word “bad.”
Dr. Boli predicts, based on a number of experiments, that you will not find it, unless it is in a quotation from the subject of the article, or in a title (like The Bad Child’s Book of Beasts, the only appearance of “bad” in the article on Hilaire Belloc). The word will not appear in the text of the article or in any quotations from modern critical assessments of the subject.
From this observation, when you need a hobby, you may spin a whole diatribe on the extinction of moral and critical clarity.
