Fifth Theory.—The actions of evil spirits or devils, personifying who or what they please, in order to undermine Christianity and ruin men's souls.

Sixth Theory.—The actions of a separate order of beings, living on this earth, but invisible and immaterial to us. Able, however, occasionally to manifest their presence; known in almost all countries and ages as demons not necessarily bad, gnomes, fairies, kobolds, elves, goblins, Puck, &c.

Seventh Theory.—The actions of departed human beings—the spiritual theory par excellence.

Eighth Theory.—(The Psychic Force Theory).—This is a necessary adjunct to the 4th, 5th, 6th, and 7th theories, rather than a theory by itself.

According to this theory the "medium," or the circle of people associated together as a whole, is supposed to possess a force, power, influence, virtue, or gift, by means of which intelligent beings are enabled to produce the phenomena observed. What these intelligent beings are is a subject for other theories.

It is obvious that a "medium" possesses a something which is not possessed by an ordinary being. Give this something a name. Call it "x" if you like. Mr. Serjeant Cox calls it Psychic Force. There has been so much misunderstanding on this subject that I think it best to give the following explanation in Mr. Serjeant Cox's own words:—

"The Theory of Psychic Force is in itself merely the recognition of the now almost undisputed fact that under certain conditions, as yet but imperfectly ascertained, and within a limited, but as yet undefined, distance from the bodies of certain persons having a special nerve organization, a Force operates by which, without muscular contact or connexion, action at a distance is caused, and visible motions and audible sounds are produced in solid substances. As the presence of such an organization is necessary to the phenomenon, it is reasonably concluded that the Force does, in some manner as yet unknown, proceed from that organization. As the organism is itself moved and directed within its structure by a Force which either is, or is controlled by, the Soul, Spirit, or Mind (call it what we may) which constitutes the individual being we term 'the Man,' it is an equally reasonable conclusion that the Force which causes the motions beyond the limits of the body is the same Force that produces motion within the limits of the body. And, inasmuch as the external force is seen to be often directed by Intelligence, it is an equally reasonable conclusion that the directing Intelligence of the external force is the same Intelligence that directs the Force internally. This is the force to which the name of Psychic Force has been given by me as properly designating a force which I thus contend to be traced back to the Soul or Mind of the Man as its source. But I, and all who adopt this theory of Psychic Force, as being the agent through which the phenomena are produced, do not thereby intend to assert that this Psychic Force may not be sometimes seized and directed by some other Intelligence than the Mind of the Psychic. The most ardent spiritualists practically admit the existence of Psychic Force under the very inappropriate name of Magnetism (to which it has no affinity whatever), for they assert that the Spirits of the Dead can only do the acts attributed to them by using the Magnetism (that is, the Psychic Force) of the Medium. The difference between the advocates of Psychic Force and the spiritualists consists in this—that we contend that there is as yet insufficient proof of any other directing agent than the Intelligence of the Medium, and no proof whatever of the agency of Spirits of the Dead; while the spiritualists hold it as a faith, not demanding further proof, that Spirits of the Dead are the sole agents in the production of all the phenomena. Thus the controversy resolves itself into a pure question of fact, only to be determined by a laborious and long continued series of experiments and an extensive collection of psychological facts, which should be the first duty of the Psychological Society, the formation of which is now in progress."

It has frequently struck me, especially in connexion with certain investigations that I have been making during the last few years, that Spiritualism is going through much the same phases as Positivism. It seemed at first impossible that the Positive Philosophy of Auguste Comte could culminate in a highly ornate Religion of Humanity, with its fall ritual, its ninefold sacramental system. It is even curious to notice that it was the death of Clotilde which brought about the change, by revealing to him the gap which Philosophy always does leave between the present and the future. So too Spiritualism is beginning to "organize" and exhibits some symptoms of formulating a Creed and Articles of Belief. The British National Association of Spiritualists, which has honoured me by placing my name on its Council, thus states its principles, under the mottoes:—

"He that answereth a matter before he heareth it, it is folly and shame unto him."—Proverbs xviii. 13.

"In Scripture we are perpetually reminded that the Laws of the Spiritual World are, in the highest sense, Laws of Nature."—Argyll.
