Huxley, Brave New World Revisited:

The demagogic propagandist must therefore be consistently dogmatic. All his statements are made without qualification. There are no grays in his picture of the world; everything is either diabolically black or celestially white. In Hitler’s words, the propagandist should adopt “a systematically one-sided attitude towards every problem that has to be dealt with.” He must never admit that he might be wrong or that people with a different point of view might be even partially right. Opponents should not be argued with; they should be attacked, shouted down, or, if they become too much of a nuisance, liquidated. The morally squeamish intellectual may be shocked by this kind of thing. But the masses are always convinced that “right is on the side of the active aggressor.

“After we came out of the church, we stood talking for some time together of Bishop Berkeley’s ingenious sophistry to prove the non-existence of matter, and that every thing in the universe is merely ideal. I observed, that though we are satisfied his doctrine is not true, it is impossible to refute it. I never shall forget the alacrity with which Johnson answered, striking his foot with mighty force against a large stone, till he rebounded from it, ‘I refute it thus.'”(Boswell’s Life of Samuel Johnson, quoted from Wikipedia.)
