A Student of Christian Science was a passenger on a transcontinental plane. He was resting, half asleep, when he was awakened by the voice of the pilot, announcing over the loud-speaker that if the passengers would look down to their left, they would see Memphis, Tennessee, on the banks of the Mississippi River. With great expectancy the student looked down to his left, but was disappointed to see nothing but miles of patchwork fields—no river and no city.
He began to reason, "The pilot would never have announced such a spectacle unless it was there. I am sure that I was not fully asleep and just dreaming that I heard the pilot's invitation."
Suddenly, as he reasoned, the answer came to him: "My point of view is wrong. I am sitting with my back to the pilot, and therefore I am in a reverse position from most of the passengers. I must look to my right in order to see what the others are seeing." He crossed the forward compartment, looked down to his right and saw the winding river and the city.
