It’s certain that I will always be doubtful and it’s doubtful that I will ever be certain.
People who are certain about almost anything scare the hell out of me! Those are the people who cause wars or kill the wrong person. Probably worse than that, they teach their children to be certain and this is where religious fanatics come from.
The real problem is not so much religion versus science - it’s certainty versus doubt. Religions don’t allow doubt and science doesn’t allow certainty and therein lies the rub!
