We either base our 'confidence' on reason (evident probabilities, past experience, competence, etc) or﻿ we base our beliefs on faith, which is blind by definition. Faith is the most dishonest position it is possible to have, because it is an assertion of stoic conviction that is assumed without reason and defended against all reason. If you have to believe it on faith, you have no reason to believe it at all.
