Posthumous Letters
Many investigators of psychic science, members of the Society for Psychic Research and others, have left sealed letters, whose contents are known only to the writer. On the death of the writer, and before the letter shall have been opened, an attempt is made by a medium to reveal the contents. By this means it is hoped to prove the actuality or otherwise of spirit communication, for, since only the writer knows what the letter contains, it is presumed that on his death this knowledge can only be communicated through his discarnate spirit. This hypothesis certainly overlooks the fact that the information might be telepathically acquired during the writer's lifetime by a still living person, and so conveyed to the medium. As yet, however, hypotheses are premature, for no attempt of the kind has met with striking success.
