Fundamental assumptions in general and scientific assumptions in particular are so hard to overturn because they are based on belief. Beliefs are so hard to overcome because they are irrational and therefore do not yield to logical argument.

Thomas CampbellBritannia needs no bulwarks, No towers along the steep; Her march is o'er the mountain waves, Her home is on the deep.
