"And you shall know the truth, and the truth shall make you free".
Isn't the "truth" of why we are here illrelevant? Only the truth that we `are', is of import to us, and what we choose to do while we are here. Checking to see if the door is lock, after we've left the House, and then rechecking again and again seems like a waste of time and lacks any rationale basis. We are out, now, what are you going to do?
