“Psychologists declare that the telepathic explanation is as valid in the latter class of cases as it obviously is in the former. Thus, telepathy being a power of the subjective mind, messages may be conveyed from one to another at any time, neither of the parties being objectively conscious of the fact. It follows that a telepathist at any following seance with the recipient can reach the content of that message. “If this argument is valid—and its validity is self-evident—it is impossible to imagine a case that may not be thus explained on psychological principles.” Professor Hudson’s argument will appeal to the ordinary reader as good. It may be simplified, however, thus: We may suppose that Mrs. Piper voluntarily hypnotizes herself. Perhaps she simply puts her conscious reason to sleep. In that condition the rest of her mind is in an exalted state, and capable of telepathy and mind-reading, either of those near at hand or at a distance. Her reason being asleep, she simply dreams, and the questions of her sitter are made to fit into her dream. If we regard mediums as persons who have the power of hypnotizing themselves and then of doing what we know persons who have been hypnotized by others sometimes do, we have an explanation that covers the whole case perfectly. At the same time, as Professor James warns us, we must believe that the mind is far more complex than we are accustomed to think it.
