Daniel Everett - Don't sleep, there are snakes

Daniel Everett, author of Don't Sleep, There Are Snakes, ex missionary, tells of how he lost his faith due to his interaction with the Pirahãs tribe in the Amazon.

"The Pirahãs have shown me that there is dignity and deep satisfaction in facing life and death without the comforts of heaven or the fear of hell, and of sailing towards the great abyss with a smile.

And they have shown me that for years I held many of my beliefs without warrant. I have learned these things from the Pirahãs, and I will be grateful to them for as long as I live."
