slimboyfat: "What if God used the stroke to switch on the dormant part of Dawkins' brain that puts him in touch with God?"
This is not too far from reality. While I don't believe God does it, I have seen people change .for two reasons. First, some become very emotional. They change from being a "thinker" to a "thinker feeler". They now see their life and the world quite differently. Or second, they realize how precious life is, and how they need to be grateful to the one who gave it. They see the brain as greater than the sum of it's parts.
