I'm pretty much in agreement with this assessment. To be honest, I couldn't slog my way through that symposium. First, reviewing and criticism are not the same thing. A review is a literary consumer's report. You read the book, give the prospective reader of it some idea of what it's about, and offer reasons why you think the book works or doesn't. I really don't think people read book reviews in order to arrive at an understanding of society. They read them in order to find out if the book being reviewed is worth their time and money.
