Another large class of psychological phenomena, which has been productive of more conflicting theories than any other, and which from time immemorial has puzzled and appalled mankind, is by a large class of persons referred to the direct agency of the spirits of the dead. It would require a volume to catalogue the various theories which have been advanced to account for this class of phenomena, and when done it would serve no useful purpose. It is safe to say, however, that no two individuals, whether believers or unbelievers in the generic doctrine of spiritism, exactly agree as to the ultimate cause of the phenomena. The obvious reason is that no two persons have had exactly the same experience, or have observed exactly the same phenomena. In the absence of a working hypothesis applicable to all the infinite variety of facts observed, it follows that each investigator must draw his own conclusions from the limited field of his own experience. And when we take into consideration the important rôle which passion and prejudice ever play in the minds of men when the solution of an undemonstrable problem is attempted, it is easy to see that a bewildering hodge-podge of heterogeneous opinions is inevitable.
Another class of phenomena, about which an infinite variety of opinions prevails, may be mentioned under the general head of mental therapeutics. Under this generic title may be grouped the invocations of the gods by the Egyptian priests; the magic formulas of the disciples of Esculapius; the sympathetic powder of Paracelsus; the king's touch for the cure of goitre; the wonderful cures at the tomb of Deacon Paris and at Lourdes; the miraculous power supposed to reside in the relics of the saints; the equally miraculous cures of such men as Greatrakes, of Gassner, and of the Abbot Prince of Hohenlohe; and the no less wonderful healing power displayed by the modern systems known as mind cure, faith cure, Christian science, animal magnetism, and suggestive therapeutics.
One fact, pregnant with importance, pertains to all these systems; and that is that marvellous cures are constantly effected through their agencies. To the casual observer it would seem to be almost self-evident that, underlying all, there must be some one principle which, once understood, would show them to be identical as to cause and mode of operation. Yet we find as many conflicting theories as there are systems, and as many private opinions as there are individuals who accept the facts. Some of the hypotheses gravely put forth in books are so bizarre as to excite only the pity or the ridicule of the judicious. One notable example is found in that system, the basic theory of which is that matter has no existence, that nothing is real but mind, and that, consequently, disease and pain, suffering and death, are mere hallucinations of morbid intellects. Other theories there are, which, if not equally absurd, are probably equally remote from the truth; and each treats the persons as well as the opinions of the others with that virulent contumely which is the ever-present resort of him who would force upon his neighbor the acceptance of his own undemonstrable article of faith. Nevertheless, as before remarked, the fact remains that each of these systems effects some most wonderful results in the way of curing certain diseases.
What is true of the phenomena embraced under the general head of mental therapeutics is also true of the whole range of psychological phenomena; namely, the want of a working hypothesis which shall apply to all the facts that have been observed and authenticated.
No successful attempt has heretofore been made to supply this want; nor has success been possible until within a very recent period, for the simple reason that previous to the discovery of certain facts in psychological science, the scientific world was without the necessary data from which a correct hypothesis could be formulated. The researches of Professor Liébault in the domain of hypnotism, seconded by those of his pupil, Professor Bernheim, have resulted in discoveries which throw a flood of light upon the whole field of psychological investigation. Their field of observation being confined to hypnotism, and chiefly to its employment as a therapeutic agent, it is not probable that either of those eminent scientists realized the transcendent importance of their principal discovery, or perceived that it is applicable to psychological phenomena outside the domain of their special studies. The discovery is this: that hypnotic subjects are constantly amenable to the power of suggestion; that suggestion is the all-potent factor in the production of all hypnotic phenomena. This proposition has been demonstrated to be true beyond the possibility of a reasonable doubt. In subsequent chapters of this book it will be shown that this fact supplies the missing link in the chain of propositions necessary for a complete working hypothesis for the subject under consideration.
The general propositions applicable to all phases of psychological phenomena are here only briefly stated, leaving the minor, or subsidiary, propositions necessary for the elucidation of particular classes and sub-classes of phenomena to be stated under their appropriate heads.
The first proposition relates to the dual character of man's mental organization. That is to say, man has, or appears to have, two minds, each endowed with separate and distinct attributes and powers; each capable, under certain conditions, of independent action. It should be clearly understood at the outset that for the purpose of arriving at a correct conclusion it is a matter of indifference whether we consider that man is endowed with two distinct minds, or that his one mind possesses certain attributes and powers under some conditions, and certain other attributes and powers under other conditions. It is sufficient to know that everything happens just as though he were endowed with a dual mental organization.
Under the rules of correct reasoning, therefore, I have a right to assume that MAN HAS TWO MINDS; and the assumption is so stated, in its broadest terms, as the first proposition of my hypothesis. For convenience I shall designate the one as the objective mind, and the other as the subjective mind. These terms will be more fully explained at the proper time.
The second proposition is, that THE SUBJECTIVE MIND IS CONSTANTLY AMENABLE TO CONTROL BY SUGGESTION.
The third, or subsidiary, proposition is, that THE SUBJECTIVE MIND IS INCAPABLE OF INDUCTIVE REASONING.
CHAPTER II.
DUALITY AND SUGGESTION.
The Doctrine of the Trinity of Man.—The Greek Philosophy.—The Early Christian Fathers.—Hermetic Philosophy.—Swedenborg.—Duality in Modern Philosophy.—"Objective" and "Subjective" Minds.—Their Distinctive Differences and Modes of Operation.—The Subjective Mind a Distinct Entity.—Illustrations from Hypnotism.—Suggestion.—Auto-Suggestion.—Universality of the Law of Suggestion.
The broad idea that man is endowed with a dual mental organization is far from being new. The essential truth of the proposition has been recognized by philosophers of all ages and nations of the civilized world. That man is a trinity, made up of "body, soul, and spirit," was a cardinal tenet in the faith of many ancient Greek philosophers, who thus clearly recognized the dual character of man's mental or spiritual organization. Plato's idea of terrestrial man was that he is a "trinity of soul, soul-body, and earth-body." The mystic jargon of the Hermetic philosophers discloses the same general idea. The "salt, sulphur, and mercury" of the ancient alchemists doubtless refers to man as being composed of a trinity of elements. The early Christian Fathers confidently proclaimed the same doctrine, as is shown in the writings of Clement, Origen, Tatian, and other early exponents of Christian doctrine.
Indeed, it may be safely assumed that the conception of this fundamental truth was more or less clearly defined in the minds of all ancient philosophers, both Christian and pagan. It is the basis of their conception of God as a Trinity in his personality, modes of existence, and manifestations—a conception of which Schelling says: "The philosophy of mythology proves that a trinity of divine potentialities is the root from which have grown the religious ideas of all nations of any importance that are known to us."
In later times, Swedenborg, believing himself to be divinely inspired, declared that "There appertain to every man an internal man, a rational man, and an external man, which is properly called the natural man." Again, he tells us that there are three natures, or degrees of life, in man—"the natural, the spiritual, and the celestial."
