Firstly, I'll deal with the printing quality of this book. This edition is clearly a copy of an earlier book, whose copyright has expired, but there is no mention of the original edition, either the publisher or year of publication. It looks like the pages were scanned and automatically converted to text. This hasn't been an entirely successful process; there are some sections of text that have not been converted from photocopy/scan into proper type. Also, the images are black and white copies of the original images and lack clarity and contrast. If you can find a good quality copy of the original book, get that instead of this book.
As for the contents of the book, it's a long diatribe, poorly argued, by an arrogant, self-absorbed elitist with no understanding of economics or the human condition. Le Corbusier states opinions as though they were facts, uses these opinions to make absolute statements of truth and admits no possibility that other opinions could have any validity.
Sadly, this approach has not lasted well through the decades. The text reads as a muddled collection of hyperbole and iconoclasm and most of the 'evident truths' stated in the book will be seen as quaint naivete from a 21st Century perspective.
There are some interesting opinions from a leading architect of the 20th Century, and some of his drawings are excellent examples of his work - if only they were reproduced at a higher quality.
If you can get a better quality of production of this text than afforded by this edition, then do so. If this edition is the only version you can find or afford, then be prepared to be disappointed.
