I think the author's point is that an unfound and irrefutable truth is not interesting. If a person holds a belief and is unwilling to accept evidence to the contrary, then that person is not interested in truth. If a person holds a belief and has made no attempt to verify it with evidence, then that person is human ... but I, for one, am suspicious of their motives proportionally to their conviction.
