Quote from Ricter:
At the very least, time spent on the bible is time away from textbooks (just like TV). So the argument is not "easily refutable". Now, is there time enough in a day for both science and religion study? Depends, what's your competition doing?
I think it also depends on your perspective.
The U.S. had 50 percent of the world GDP when the bible was still being taught in schools. Since the 1950s when the courts started taking the bible out of schools our share of world GDP dropped to 25% and we have become a debtor/consumer/half a family country. Our institutions are now driven by marketing and spin. Walls Street went from long term greedy to blow up the world economic system greedy.
Is there a correlation?
