His focus is on style and structure above all else. Pretty compelling, there are a bunch of works I need to reread now.
Halfway through Kaddish (started in August), need to get that finished this month so I can start on my next "remembrance reading": George Bernard Shaw's Man and Superman and Three Other Plays. Will explain why when I start it.
I've also started to read Axel's Castle: A Study of the Imaginative Literature of 1870-1930, by Edmund Wilson. Edmund Wilson was a correspondent of Nabokov's, and actually persuaded Nabokov to teach Mansfield Park in his lectures on great authors.
