Doesn't belief just mean what one holds to be true?
If what you believe (hold to be true) is based on evidence and reason, and is what is actually so, that is knowledge.
If what you believe (hold to be true) is based on anything other than evidence and reason, such as inspiration, revelation, mystic insight, intuition or mysticism and has no basis in fact it is faith (or superstition).
When someone says, "this is what I believe," it only means what their view of truth is, not how they arrived at that view.
That's the way I've always understood it. Belief does not mean faith, faith is just mistaken belief.
Not arguing the point. Really curious about what others think about it.
