3608. THAT THE IDEAS OF SPIRITS ARE BOUND TO PLACE AND THE THINGS OF PLACE. Upon my conveying myself into an adjoining chamber, from whence I was to pass back into the former, it immediately seemed to me as if a solitude had been created, and the spirits had withdrawn from me, when yet they were present in the adjacent room, where were my books and other things, which they had seen. Hence it may be inferred that such things are in the ideas of spirits; in those of some, the things pertaining to books, in those of others, the things pertaining to utensils, in those of others the things of light, fire, and other matters connected with these, so that when they were left, and were not seen in the other chamber, they seemed themselves to have disappeared; for they are present according to their ideas, to which, if such objects are wanting, they seem themselves to withdraw.
