But supposing it to be solved, the problem still remains almost intact. If the knowledge of a positive fact, certainly unknown to the medium, appears in his automatic communications, we must not thereupon conclude that this knowledge is due to the intervention of a disincarnated spirit. Telepathy may be able to explain it. Telepathy is, as we know, the transmission of an idea, an impression, a psychical condition of some kind or other from one person to another. We are altogether ignorant of its laws, and nothing warrants the assertion, that if telepathy is a fact—as appears most probable—it is therefore necessary that any particular motive condition should exist in the agent. We may suppose with just as much reason, that the existence of a souvenir in one mind can be discovered and recognised by another, under conditions solely depending on the mental state of the percipient. This is, properly speaking, telesthesia. Now it is very difficult to prove that the fact, of which automatism marks the knowledge, is unknown to everybody. It is even impossible to prove it. But supposing this were done, there would always remain the possibility of attributing the communication to some being other than human: by admitting even the existence of spiritual or immaterial beings distinct from ourselves, nothing warrants us to affirm that such beings are our deceased relatives or friends and not some facetious Kobolds. Prediction and precognition, of which I have had proof, raise just as complicated questions as the preceding ones. I confine myself to recording without trying to explain these facts.
