Despite what people are saying, this book is a classic. People made it a classic because it was that good. We cannot accuse an old book of being boring simply because we've been force fed the same message over and over again. This book was in many ways the beginning of this philosophy. So what I'm saying is, this book laid the ground work for a lot of other theories. While it seems like "duh!" so did gravity, but because someone "realized it" they got credit for it, and so should Mr. Gray.
