"Religion must be incomprehensible to be successful, says Dennett."
Not sure what he means by this since it isn't in the text of the article, but under a photo of the Vatican.(I think it's the Vatican)
I think he means there must be an element of mysticism to religion to make it successful. The human mind is perfectly capable of attaching complicated meanings to what should be kept simple. Evolution, so to speak, rips that veil away from the world and makes everything clear again. No wonder religions feel hostile towards it for it makes their role superfluous. If you can explain the processes of life in terms of empirical data, what do you need the supernatural for? That's where Darwin undermined the traditional explanations for how life adapts on the planet and religion hasn't managed to recover that former authority it once commanded.
