Query: Worth the time spent reading!

Mumford has got to be one of the most over-looked (by main-stream) social critics of our time. He covers and unravels our confusing society so well, even though this book was written some time ago. Mumford's points ring quite true even in the 21st century.Lengthy read but, for those who are serious about making sense of "why" things are they way they are here in the "civilized" world, Mumford is worth it.
