Honesty is not the same as truth. That is the obstacle of the notion of relative truths. I would like to put my trust in the lunatic. He is the one least concerned of what I think of him, the mark of an honest man. I can always depend on him to be completely honest in what he thinks and feels, about anything, no matter the consequences laid before him, however with no course of rationale, I cannot necessarily take his word for even the well-being of him in his own reality.
