  HENRY GRADY WEAVER 
  \'~Ulpl-e.. 
  FOR SIX THOUSAND YEARS ~DIED OF HUNGER. 
  WHY DON'T WE? 
  This is the basic question dealt with in MAINSPRING. 
  But the attempt to find the answer leads into a wide range 
  of subjects, such as: 
  • What is the greatest of all our modern inventions? 
  • Who invented ¥¥~¢ (0) and why? 
  • Just what is the difference between a ~~public and 
  a pemocracy? 
  • What simple invention contributed most to our 
  national wealth?...
