Let just one case serve as an example. Spirits partly in error, and partly wicked, had assumed as a proposition to be proved, the falsity that a spirit can enter the body of a person on earth, and thus live in the body. They tried to prove it at once by the fact that a spirit with a person supposes that he is the person. But when I said this was not the case, they did not want to pay attention to reasons, because they had assumed the falsity as a premise, and therefore wanted to corroborate it. The fact of the matter is, however, that because the spirit at such a time thinks, understands, and wills the same as the person he is with, and this is followed by action, therefore he imagines that he is the person. But this does not last long; only during those states of mind in which there is agreement.
