Contagious Beliefs

If your beliefs are entangled with reality, they should be contagious among honest folk. And that is why I personally don't trust religious because they have access to special revelation and the rest of us just have to believe them. But then like, I don't know. They know that you're. Infected. That's there's a word for contagious and it's not contagious. What on earth would culture have to do with it? The author says he doesn't expect people in a different culture than him to necessarily be contagious by my ideas.
