“It should not be a crime to discuss any idea, however outrageous ”

“Intelligent people discuss ideas. Fools discuss how people should behave.”

“All ideas in a truly free society should always be open for discussion.”

“It was the shame we knew so well, the shame that drowned us after the selections, and every time we had to watch, or submit to, some outrage: the shame that the Germans did not know, that the just man experiences at another man's crime; the feeling of guilt that such a crime should exist, that it should have been introduced irrevocably into the world of things that exist, and that his will for good should have proved too weak or null, and should not have availed in defense.”

“Great minds discuss ideas. Average minds discuss events. Small minds discuss people.”

“Strong minds discuss ideas, average minds discuss events, weak minds discuss people.”
