I don't really understand the self-perpetuating cycle of pulling out quotes from this sceptic or that believer to vilifiy or justify faith.
It shoud always be down to an individual's personal experience. I am a person of faith, but I didn't reach that place due to reading what so-called experts have to say on the matter. But then, maybe that requires faith in the first place...
I was talking to a physicist on Friday evening about the idea of faith. He said that, as a scientist, faith is essential to him; his work in the lab is more often than not faith-based. Think it through.
The question in the OP is "Is Faith Dangerous?" The answer, IMO, is "of course not". If it is, then it should be applied across the board which means that scientists around the world better get the hell out of the lab.
Faith within scientists has led to them changing the world.
Faith within Christians has led to them changing the world.
