Thanks to the CBC, here is a clip of Robertson Davies, on critics:
I like this for two reasons. First, Davies' mischief peeps through for a moment there. You can see him thinking, "I'm on Telly, and do I really want to deliver the smackdown?" and then the answer: "Yes." Also,he's not wrong. Even the good critics can mess up a writer by luring the writer to aim for that critic. (John Mortimer has a great take on this in Rumpole and the Show Folk, where Rumpole's dramatic techniques are pointed out to him by a pro, and he then overdoes them). As for the bad critics. . . well, the less said the better.
Second, I remember attending a reading Davies gave, shortly before his death, and his seeing him younger was interesting--he had great presence, and the High Manner.
