"All our knowledge is the offspring of our perceptions."

Previous Quote

The responsibility which rests upon man is proportional to the ability which he possesses and the opportunity which he faces. Perhaps that responsibility is no greater for him than was that of Notharctus or Eohippus or a trilobite, each in his own day, but because of man's unique abilities it is the greatest responsibility that has ever rested upon any of the earth's offspring.
