"Many people used to believe that angels moved the stars. It now appears that they do not. As a result of this and like revelations, many people do not now believe in angels. Many people used to believe that the 'seat' of the soul was somewhere in the brain. Since brains began to be opened up frequently, no one has seen 'the soul'. As a result of this and like revelations, many people do not now believe in the soul. Who could suppose that angels move the stars, or be so superstitious as to suppose that because one cannot see one's soul at the end of a microscope it does not exist?"
