“A book is simply the container of an idea—like a bottle; what is inside the book is what matters.”
Expletives Deleted: Selected Writings (1992).
Language Education in a Knowledge Context (1980)
Context: Of writing that is filled with mechanical and grammatical error, as compared with writing that conforms to the rules of standard edited English. Surely, we do not want to say that there is a necessary correlation between mechanical and editorial accuracy and intellectual substance. There are many books that are mechanically faultless but which contain untrue, unclear, or even nonsensical ideas. Carefully edited writing tells us, not that the writer speaks truly, but that he or she grasps... the manner in which knowledge is usually expressed. The most devastating argument against a paper that is marred by grammatical and rhetorical error is that the writer does not understand the subject.
