“I've said that anyone who doesn't contradict himself is a dogmatist, and every dogmatist is a reactionary.”

“There are two kinds of people in the world, the conscious dogmatists and the unconscious dogmatists. I have always found myself that the unconscious dogmatists were by far the most dogmatic.”

“There is no absolute knowledge. And those who claim it, whether they are scientists or dogmatists, open the door to tragedy.”

“The dogmatist within is always worse than the enemy without.”

“Many orthodox people speak as though it were the business of sceptics to disprove received dogmas rather than of dogmatists to prove them.”

“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. If the conviction of rightness is powerful enough, resistance to it will be met, sooner or later by force. There are people like this in every sphere of life, and it is natural to feel that the world would be a better place without them!”
