There are no absolute certainties in this universe. A man must try to whip order into a yelping pack of probabilities, and uniform success is impossible.
He changes his opinions as he does his friends, and much on the same account. He has no comfort in fixed principles; as soon as anything is settled in his own mind, he quarrels with it. He has no satisfaction but the chase after truth, runs a question down, worries and kills it, then quits it like a vermin, and starts some new game, to lead him a new dance, and give him a fresh breathing through bog and brake, with the rabble yelping at his heels and the leaders perpetually at fault.william hazlitt
