TMoP Coetzee's thematic reverberations, maybe?

[Mark Kohut]

I want to state it baldly. 

One major theme of TMoP is that Coetzee
wants to show how a great work of fictional art, The Demons, illuminating the real evil of an historic movement of the time is created by a writer--D.--himself 
full of contradiction (and therefore some bad shit which he has to 'know' to get into his fiction) which could only be put down
in the illuminating fiction of The Master of Petersburg by a writer
full of contradiction--some bad shit including the internal horror of his son's mysterius death--- himself. 

Coetzee wants to 'say' D.'s "The Demons" may be 'wrong' because D. is so flawed, yet it is right because D. FEELS the evil in himself that he sees
in the characters of "The Demons".....

As Coetzee feels in 'understanding' Dosteovsky as D.

???

Both--all---are "true' as only fiction allows.......
