Bernhard is fantastic. Woodcutters might be a gentler introduction to his style. It's shorter, funnier, and less oppressive than Correction, which is his magnum opus. Apparently he was at least somewhat as unhinged in real life as in his writing. He was notorious for insulting the Austrian intelligentsia and either refusing literary awards or showing up at the ceremony just to rant and insult the audience, which he wrote about in a memoir titled My Prizes. He was a big influence on W.G. Sebald, another great German language writer (my personal favorite) who makes an appearance in McCarthy's library.
McCarthy made his famous dismissal of Proust and Henry James in the NYT in 1992 and in the Oprah interview, on the grounds those writers didn't deal with deep issues of life and death. But from all that has been revealed about his personal library, including this Bernhard book, one wonders if that was a put-on.
I like Bernhard. I also recommend The Lime Works and wittgenstein’s nephew if you like correction. I found Bernhard through Thomas Ligotti. For Ligotti I recommend teatro grottesco and if you want to dive off the deep end the conspiracy against the human race.
