George Eliot

 

 

             It is astonishing what a different result one gets by changing the metaphor! Once call the brain an intellectual stomach, and one’s ingenious conception of the classics and geometry as ploughs and harrows seems to settle nothing. But then, it is open to someone else to follow great authorities and call the mind a sheet of white paper or a mirror, in which case one’s knowledge of the digestive process becomes quite irrelevant. It was doubtless an ingenious idea to call the camel the ship of the desert, but it would hardly lead one far in training that useful beast. O Aristotle! if you had the advantage of being ‘the freshest modern’ instead of the greatest ancient, would you not have mingled your praise of metaphorical speech as a sign of high intelligence, with a lamentation that intelligence so rarely shows itself in speech without metaphor,—that we can so seldom declare what a thing is, except by saying it is something else?
