Shaving off the false

In Dr. Lane's "Believer-Skeptic" he attempts to give the reader the right tools to find the truth - whatever the truth maybe. He believes the greatest tool or quality we can have is our ability to doubt. Which, of course, goes against every fiber in our being. When I would ask a spiritual question growing up the response was "Don't doubt - believe, have faith." Or don't be a "Doubting Thomas. He was humiliated in front of Christ." Doubt was akin to a character flaw.
I was surprised to find out that Faqir Chand was a believer in Edgar Cayce. I have read all of Cayce's books and found his altered states fascinating. But I never really knew what to make of it. I just thought that we humans are so desperate to believe in spirituality and life after death it's easy to believe in what we can't explain away.
