"The right to search for truth implies also a duty; one must not conceal any part of what one has recognized to be true."--Albert Einstein
"...that truth is great and will prevail if left to herself, that she is the proper and sufficient antagonist to error, and has nothing to fear from the conflict, unless by human interposition disarmed of her natural weapons, free argument and debate, errors ceasing to be dangerous when it is permitted freely to contradict them. "
--Thomas Jefferson
