This book is valuable both for lit folk and poets. Although I'm not a big reader of George Herbert, there were still some useful and interesting bits in that chapter. Whitman I love, and Ashbery I struggle with, so those chapters were more captivating. I don't buy every argument, especially when it comes to Ashbery, but much was illuminated about each poet and specific poems, and lyric poetry in general. I also appreciate the lucidity of Vendler's prose.
