like titles says... 1st section is useful. Essays themselves are outdated and not really written well. Author says himself that he was not under pressure of time and had time to think it thru, in the end all his essays contain some sort of reference to work of Shakespier or some statistics. How sitting on GRE test I will come up with all these sources? So do not waste your time on 2 nd 3 rd part of this book, but do read thru the 1st one!
