One night after dinner a group of us were talking about the supernatural, and one of our dinner guests said that when the electric light was invented, people began to lose the dimension of the supernatural. In the days before we could touch a switch and flood every section of the room with light, there were always shadows in the corner, shadows which moved with candlelight, with firelight; and these shadows were an outward and visible sign that things are not always what they seem; there are things which are not visible to the mortal human being; there are things beyond our ken.
