Richard Dawkins at his own website:
You have surely heard something like the following two statements, often uttered with a measure of truculence:-
1. “There are 1.6 billion Muslims, nearly a quarter of the world’s population, and we are growing fast.” There is even, sometimes, a hint of menace added. In the words of Houari Boumediene, President of Algeria, “Le ventre de nos femmes nous donnera la victoire” (the belly of our women will give us the victory).
2. “Islamic science deserves enormous respect.” There are two versions of this second claim, ranging from the pathetic desperation of “the Qu’ran anticipated modern science” (the embryo develops from a blob, mountains have roots that hold the earth in place, salt and fresh water don’t mix) to what is arguably quite a good historical point: “Muslim scholars kept the flame of Greek learning alight while Christendom wallowed in the Dark Ages.”
Putting these two claims together, you almost can’t help wondering something like this: “If you are so numerous, and if your science is so great, shouldn’t you be able to point to some pretty spectacular achievements emanating from among those vast numbers? If you can’t today but once could, what has gone wrong for the past 500 years? Whatever it is, is there something to be done about it?”
