"Look at this spoon," Bill Sprague said, taking it off the table and holding it up. "Inside it are pulsing hundreds of minute electrical currents, set up by all the radio broadcasting stations in the world. That can be proven by attaching a powerful radio to it and using it as an antenna. Currents so minute and subtle that they can't be measured, but they're there. Today we have all sorts of scientific devices for measuring and detecting subtle forces. And why can't they detect the soul?"
