The arrogant skeptic is condescending. I remember a young man who grew up in a Christian church but was going through a period of doubts. He berated his mild-mannered girl friend regarding her faith by saying, “You don’t believe that for yourself. You’re just repeating what somebody else told you.”
You can believe what someone else told you if it’s true. Enough people have told me about kidney stones that I never want to check out that condition personally.
