  DOWN ZHONGNAN MOUNTAIN
  TO THE KIND PILLOW AND BOWL OF HUSI
  Down the blue mountain in the evening,
  Moonlight was my homeward escort.
  Looking back, I saw my path
  Lie in levels of deep shadow....
  I was passing the farm-house of a friend,
  When his children called from a gate of thorn
  And led me twining through jade bamboos
  Where green vines caught and held my clothes.
  And I was glad of a chance to rest
  And glad of a chance to drink with my friend....
  We sang to the tune of the wind in the pines;
  And we finished our songs as the stars went down,
  When, I being drunk and my friend more than happy,
  Between us we forgot the world.

  «Se os seus factos estão errados, mas a sua lógica é perfeita, então as suas conclusões são obviamente falsas. Assim, ao errar na sua lógica, tem pelo menos uma hipótese académica de chegar a uma conclusão correcta.»
