"In ancient times, people weren't just male or female, but one of three types: male/male, male/female, female/female. In other words, each person was made out of the components of two people. Everyone was happy with this arrangement and never really gave it much a thought. But then God took a knife and cut everybody in half, right down the middle. So after that the world was divided just into male and female, the upshot being that people spend their time running around trying to locate their missing other half."

How ignorant we are! How ignorant everyone is! We can cut across only a small area of the appallingly expanding fields of knowledge. No human being can know more than a tiny fraction of the whole. It must have been satisfactory in ancient times when one's own land seemed to be the universe; when research studies, pamphlets, books did not issue in endless flow; when laboratories and scientists were not so rapidly pushing back frontiers of knowledge that the process of unlearning the old left you gasping for breath.
