Robert Anton Wilson said this quote
“ Belief in the traditional sense, or certitude, or dogma, amounts to the grandiose delusion, My current model -- or grid, or map, or reality-tunnel -- contains the whole universe and will never need to be revised. In terms of the history of science and knowledge in general, this appears absurd and arrogant to me, and I am perpetually astonished that so many people still manage to live with such a medieval attitude. ”
