I found myself continually wondering why the book had nothing to say about the current social justice movement; it was so spot on about everything, I figured it had to have been written recently. If you consider 60 years ago to be "recent", I guess that's true.
This book doesn't have a lot of good things to say about human nature, nor is it very happy, but I found myself completely enthralled. By far the best book I've read in the last few years.
