Sted in this kind as in the other. He never learned to mind only his own business, but was always childishly inquisitive, so he never was so sure of things as was Frank's father. Still, it takes all sorts of people to make up a world, and if a person cannot be like Frank's father, it is not so bad to be like Faraday. Frank's father would have been shocked at Faraday's first introduction to the problems of metaphysical speculation. "I remember," he says, "being a great questioner when young." And one of his first questions was in regard to the seat of the soul. The question was suggested in this way.

He got his head through, but he could not get it back. Then the physical difficulty suggested the great metaphysical question, "On which side of the fence am I?"
