None of us like uncertainty. That's why we cling so closely to our suppositions. Beliefs, like opinions, give us a sense of comforting reassurance. People who try to prove us wrong become the 'enemy'. People who share our view are our 'friends.' They will support us in developing a view that takes away doubt and confusion and gives us, instead, a sense of understanding and clarity. But what if that's false? Better to allow ourselves to be doubtful than to fall for a tempting but dangerous delusion.
