446. I have spoken to spirits about the opinion held by people living at the present time, namely that they do not believe in the existence of the spirit because they neither see it with their eyes nor comprehend it through natural science. Consequently they not only deny that the spirit is dimensional, but also that it is a substance, for they disagree over what substance is. And because they deny that the spirit is dimensional and disagree about what substance is, they also deny that the spirit exists within anything spatial, and so deny its existence within the human body. Yet even a very simple person is able to know that his soul or spirit resides within his body. When I commented on this, spirits of a more simple type were amazed that men nowadays could be so stupid; and when they heard about the technical terms which men argue about such as parts outside parts, and the like, they called such things absurd, ludicrous, and farcical, which ought never to be in people's minds at all since they block the road to real understanding.
