A person who has a cat by the tail knows a whole lot more about cats than someone who has just read about them.
Mark TwainNevertheless we have this curious spectacle: daily the trained parrot in the pulpit gravely delivers himself of these ironies, which he has acquired at second-hand and adopted without examination, to a trained congregation which accepts them without examination, and neither the speaker nor the hearer laughs at himself. It does seem as if we ought to be humble when we are at a bench-show, and not put on airs of intellectual superiority there.
Mark Twain
