Publisher's Synopsis
There is a very large class of persons alive to-day who believe that not only is communication with the dead possible, but that they themselves have had actual experience of it. Many of these are eminent in scientific research, and on any other subject the world in general would accept their evidence. There is possibly a larger class of persons who hold that all such communications, if genuine, come not from the dead but from the devil. This is the taught opinion of the Roman Catholic Church.
