I said further that the erudite fully believe the soul that lives on after death—the spirit—is abstract thought. Obviously, then, they refuse to accept any term that involves dimension or anything implied by dimension. Thought has no extension apart from the person thinking, but the person thinking and the objects of thought do have extension. Moreover, if the objects of thought are not dimensional, people objectify them and make them three-dimensional in order to understand them.
From this it is abundantly clear that intellectuals take the soul or spirit to be nothing but pure thought. The consequence is an unalterable belief that the soul will vanish when they die.
I spoke with some spirits about the attitude of people alive on earth today who reject belief in the spirit because they cannot see it with their eyes or grasp it scientifically. They deny not only that a spirit has dimension but also that it has substance, because they argue about what substance even is. And since they deny its dimensionality and argue about its substantiality, they also deny that it exists in a place or, consequently, in a human body. The most simple-thinking people, however, can understand that their soul or spirit has its own body.
When I said these things to the spirits, who happened to be among the more simple-thinking, they expressed their amazement that people today could be so stupid. When they heard the terminology that was being argued over (parts outside of parts, and so on), they called it jarring, absurd, and pretentious. They said that such things should never take up mental space because they block the path to true understanding.
