Its well researched, Ill give Paddle that much. However, he is really preachy. I think he is trying to disprove everyone else, but is going about it all wrong. In my opinion, he comes across as being an ass. Just really turns me off that I spent $20 to read him argue and I find it hard to tolerate. Personally, I prefer the books by Dr. Eric Guiler or David Owen. Can get the well researched information without the rest. ( )
