Certitude leads to violence. This is a proposition that has an easy application and a difficult one. The easy application is to ideoologues, dogmatists, and bullies--people who think that their rigtness justifies them in imposing on anyone who does not happen to suscribe to their particular ideology, dogma or notion of turf.
