Just remembered the book title I was trying to think of. The copyright of the book is up so here is a link to an online copy.

I thought it was an interesting read although I'm sure some will sit there and scoff at the ideas contained within. It does contain some hokey bits as it looks like the author was a believer in a God, but none the less I think there's some interesting psychological principles that he also examines.
