In theater or movies you see either 'I'm religious' or 'I'm an atheist.' I've never seen too much discussion of 'I believe there's a higher power but I'm hesitant to reach out to him because I don't know if I'm worthy of his attention.'
Ignorance more frequently begets confidence than does knowledge: it is those who know little, not those who know much, who so positively assert that this or that problem will never be solved by science.
