> Beliefs are the same, and a relation to "facts" or "truth" is not a requrement for their utility.

Let's apply a little recursion here, shall we? I gather that you believe what I quoted. But you admit that your belief does not need to have any relation to facts or truth. You believe what you said, because that belief has some utility to you. But why should I believe you?

That is, your view, applied to itself, destroys itself.
