What a life.
One of the last sentences in the link is interesting for debate. Will Mailer be remembered? Will he influence other writers like Hemingway? I'm not sure. I don't know if his work, on the whole, was strong enough to be put in the main canon, nor am I sure that his writing is stout enough to overcome his personal problems. A debate about Faulkner, for instance, will always end up at the work; a debate about Mailer will alway end up at a stabbing.
Still, I felt like when I read The Executioner's Song that I had never read anything like it. There might still not be anything out there like that book, all these years later. The closest thing is maybe In Cold Blood, but Mailer is so much more honest than Capote was as a writer.
