“I think that we are both agnostic at heart. I just have no knowledge about the god you have a deep religious non-belief in. When you understand why you have a non-belief in something you cannot justify, you will understand why I have no knowledge of your non-beliefs.”
There is no absolute knowledge. And those who claim it, whether they are scientists or dogmatists, open the door to tragedy. All information is imperfect. We have to treat it with humility.
