Overall this is a very good book, but with some significant flaws. The first 100 pages are unbelievably good; as I began reading this book I really felt like I had hit the jackpot, and I quickly concluded I would attempt to read all of Maslow's works. As I got further into the book I was singing quite a different tune. I believe anyone with any interest in psychology whatsoever should buy this book and read the first 100 pages. This section alone is easily worth the price of the book - don't let me scare you away from exploring the ideas of this great man. However, the dropoff in quality after this first section is rather precipitous, and while pages 100-200 were OK, the final 100 pages are an absolute chore to get through and I had to force myself along to finish the book.
Keep in mind that Abraham Maslow died before he was able to make a final edit of this book, and it shows. The second half of the book is almost a verbatim repetition of the earlier sections, and Maslow tends to harp on the same concepts endlessly. Some of it comes across as a very generic self help book designed to be consumed by the masses. In other sections, he seems to start over right from square one, as if some of the essays were meant to stand alone and were not meant to follow other essays that were extremely similar. I would say nearly half of this book should have been relegated to an expanded appendix - but I guess it would be strange to have a book where full half of it consisted of an appendix. I'm sure that Maslow would have fixed these problems had he lived long enough, but we will just have to accept this book for what it is and try as best we can to extrapolate something useful from it.
To conclude, I must still vehemently stress the importance of at least the first half of this book. If you grow bored with it, just stop reading. The editors of this book obviously elected to take a throw-it-all-against-the-wall-and-see-what-sticks approach, and I suppose there is no harm in that. Just remember that the original author was not around to oversee the final editing, and the result is a large dose of disjecta and detritus towards the end of the book. Nevertheless, do not let this minor disclaimer prevent you from exploring the wonderful ideas of this brilliant man.
