There are interesting facts about him here, but I wonder how true this is:
A colleague who has worked with him for more than a decade claims to have seen him laugh just once. An acquaintance has attended several dinner parties where Coetzee has uttered not a single word.Perhaps they were dinner parties like this. And it's not hard to imagine someone who doesn't drink getting pretty quiet if everyone else is a bit drunk. The Wikipedia article gives reason to believe that the moral and political views expressed in his books are his own. I imagine he presents them as possible points of view, and possibilities worth reading about, because he believes them but recognizes that he might be wrong, or might be seeing things from just one of multiple possible and reasonable points of view. But you can never be sure when things are fictionalized. In Diary of a Bad Year he says that at the end of Kurosawa's The Seven Samurai the samurai offer to protect the village for a price but leave when asked to do so by the villagers. But as I remember the film, the samurai simply leave. There are different versions of the film, but accounts of the plot that I've read all agree with my memory of the ending, and to the extent that the film has a plot it would be quite changed if the samurai seriously considered taking the bandits' place. So I'm not sure what to make of this.
I was going to try to say something about Coetzee on teaching and on the self, but that will have to wait for other posts.
