although dover thrift editions are good for those of us who have very little money, i want to warn others, like me, who are not willing to scrape the bottom of the barrel. i made the mistake of ordering this and the symposium thrift editions and do regret it... i should have known that holding this book in my hands would be frustrating due to its awkward size and pagination. the words are crammed together and difficult to look at. (these cheapies make one aware that there is something to the art of publishing.) if you are sure that there is no other way you will read these important works, then, by all means, go ahead... but if you have to give up that cup of coffee tomorrow morning instead of going the cheapest route: please do so! i don't think you will regret it!
