I spoke with spirits and noticed that because I demonstrated a point and was convinced, they became convinced regarding matters of which they could have no knowledge. So it happened many times and on a variety of subjects, even scientific ones with which they were not familiar, as also in the case of numerous personal ones. Therefore I came to the conclusion, as I also told the spirits, that they judge and affirm things on the basis of my own conviction, so that even if I should prove something wrongly, they would still be convinced. For when it comes to personal matters, they are unable to judge for themselves, although they think that the knowledge that is in my memory is theirs. Thus they possess people, even to the point of indignation when I told them that they do not know that point, but have it from me.
