People tend to create their own conclusion boxes. The assumptions that make up the box are not carefully evaluated. The author doesn't ask that the evidence be examined or that the Truth be sought. Similar statements have also been made by Mormon leaders. Truth does not begin with an answer on behalf of which all questions must constantly rearrange themselves.
Truth begins with fearless questions.
To me, this paradox is the most puzzling aspect of human behavior. People require evidence and use scientific methodologies in certain situations but see no contradiction when they rely completely on faith in other situations. We all too frequently base our observations and decisions on opinions and personal projections rather than actual facts and evidence. Our own background, prejudices, and hopes cloud our view. I don't pretend to have a quick and easy solution to these questions.
