So a person that thought the world is round when everyone was saying flat was a fool?
I want you to take another look at what you quoted from me. Here it is:
It's really quite simple dude: Only fools believe something is true when they don't KNOW it's true. End of story.
Notice the bolded, italicized, underlined text.
In the past, before the shape of the earth were verifiable, both were fools, because no one KNEW what shape the earth was. I'm not getting how the point I made seems to be so difficult for you to grasp. It is, as I said, very simple. Children grasp this concept. Belief is justified by KNOWLEDGE. Without KNOWLEDGE, a belief is not justified. Without KNOWLEDGE, a belief is classified as delusion. How many more ways do I need to say it before you grasp it?
