"There are things in the universe that are greater than ourselves, and to think that we have a perfect answer for everything is incorrect and very arrogant indeed."
Who is saying that? Richard Dawkins would never, ever say that. As a scientist he would say (and I've heard him say it) that science is continuing to advance human knowledge and we don't know everything yet. I don't see him as arrogant, just very intelligent and a superb debater.
