"For the first time in our tradition there was a complete separation between killing and curing. Throughout the primitive world the doctor and the sorcerer tended to be the same person. He with power to kill had power to cure, including specially the undoing of his own killing activities...This is a priceless possession which we cannot afford to tarnish, but society always is attempting to make the physician into a killer— to kill the defective child at birth, to leave the sleeping pills beside the bed of the cancer patient. It is the duty of society to protect the physician from such requests."
