Have you ever heard of a little thing called the internet? If so, you won't want to miss Joshua Cohen's discussion of his latest book, Four New Messages. We broach such subjects as materialism, privacy, identity, and art, all framed around this practically impossible-to-answer question: Just what the hell is this internet thing, and what does it mean to us? Joshua is the author of five books, including A Heaven of Others and the critically acclaimed Witz. Four New Messages, published by Graywolf Press, will be coming out in August.
