It has been shown that races have existed, and exist still, at so low a level that their scanty stock of words has to be supplemented by gestures, rendering converse in the dark next to impossible. Such people are bewildered by any effort to count beyond their fingers; they have no idea of the relation of things, or of their differences; they have no power of generalisation by which to merge the accidental in the essential. They believe that their names and likenesses are integral parts of themselves, and that they can be bewitched or harmed through them at the hands of any one who knows the one or has obtained the other. As an important result of their confusion between the objective and the subjective, we find a vivid and remarkable belief in the reality of their dreams. The events which make up these are explained only on the theory that if the body did not move from its sleeping place, something related to it did, and that the people, both living and dead, who appeared in dream and vision, did in very presence come. The puzzle is solved by the theory of a second self which can leave the body and return to it. For the savage knows nothing of mind. The belief in this other self is strengthened (possibly more or less created) by its appearance in shadow or reflection, in mocking echo, in various diseases, especially fits, when the sufferer is torn by an indwelling foe, and writhes as if in his merciless grasp. The belief in such a ghost-soul, as to the form and ethereal nature of which all kinds of theories are started, is extended to animals and lifeless things, since like evidence of its existence is supplied by them. The fire that destroys his hut, the wind that blows it down, the lightning that darts from the clouds and strikes his fellow-man dead beside him, the rain-storm that floods his fields, the swollen river that sweeps away his store of food—these and every other force manifest in nature add their weight to the inferences which rude man has drawn. The phenomena which have accounted for the vigour of life and the prostration of disease account for the motion of things in heaven above and the earth beneath, and the barbaric mind thus enlarges its belief in a twofold existence in man to a far-reaching doctrine of spirits everywhere. Step by step, from ghost-soul flitting round the wigwam to the great spirits indwelling in the powers of nature, the belief in supernatural beings with physical qualities arises, until the moral element comes in, and they appear as good and evil gods contending for the mastery of the universe. Passing by details as to the whereabouts of the other self and its doings and destiny in the other world which the dream involves, and following the order of ideas on scientific lines, two queries arise:—

1. Does the evidence before us suffice to warrant the conclusions drawn from it as to the serious and permanent part which dreams have played in the origin and growth of primitive belief in spirits; in short, of belief in supernatural agencies from past to present times? In this place the answer is brief. Of course the antecedent conditions of man’s developed emotional nature, and of the universe of great and small, which is the field of its exercise, are taken for granted.

The general animistic interpretation which man gives to phenomena at the outset expressed itself in the particular conceptions of souls everywhere, of which dreams and such-like things supplied the raw material. If they did not, what did? Denying this, we must fall back on a theory of intuition or on revelation. As to the former, it begs the whole question; as to the latter, can that which is itself the subject of periodical revision be an infallible authority on anything?

If dreams, apparitions, shadows, and the like, are sufficing causes, then, in obedience to the Law of Parsimony (as it is termed in logic), we need not invoke the play of higher causes when lower ones are found competent to account for the effects. If it seems to some that the base is too narrow, the foundation too weak for the superstructure, and that our metaphysics and our beliefs regarding the invisible rest upon something wider and stronger than the illusions of a remote savage ancestry, the facts of man’s history may be adduced as witness to his continuous passage into truth through illusions; to the vast revolutions and readjustments made in his correction of the first impressions of the senses. There is not a belief of the past, from the notions of savages about their dreams and ghost-world to those of more advanced races about their spirit-realms and its occupants, to which this does not apply. In the more delicate observations of the astronomer he must, when estimating the position of any celestial body, take into account its apparent displacement through the refractive properties of the atmosphere, and must also allow for defects of perception in himself due to what is called “personal equation.” And in ascertaining our place in the scale of being, as well as in seeking for the grounds of belief concerning our own nature, we have to take into account the refracting media of dense ignorance and prejudice through which these beliefs have come, and to allow for the confirming error due to personal equation—fond desire. The result will be the vanishing of illusions involving momentous changes in psychology, ethics, and theology. Instead of groping among mental phenomena for explanations of themselves, they will be analysed by the methods already indicated. Instead of resting the authority for moral injunctions on innate ideas of right and wrong, and on inspired statutes and standards, it will rest on the accredited, because verifiable, experience of man. Instead of finding incentives to, or restraints on, conduct by operating on men’s hope of future reward, or fear of hell as “hangman’s whip to keep the wretch in order,” they will be supplied by an ever-widening sense of duty, quickened by love and loyalty to a supreme order, in obedience to which the ultimate happiness of humanity in the life that is will be secured.

In this, and not in theories of an hereafter whose origin and persistence are explained, will man find his satisfaction, and the springs of motive to whatever is ennobling, lovely, and of good report. With the poet, who, laying bare the sources of the unrest of his time, has led us to the secret of its peace, he will ask—

“Is it so small a thing
To have enjoyed the sun,
To have lived light in the spring,
To have loved, to have thought, to have done,
To have advanced true friends, and beat down baffling foes—
That we should feign a bliss
Of doubtful future date,
And while we dream on this,
Lose all our present state,
And relegate to worlds yet distant our repose?”[94]

2. Does the theory of evolution in its application to the development of the spiritual nature of man, and to the origin and growth of ideas, find any breach of continuity? In its inclusion of him as a part of nature, in accounting for his derivation from pre-human ancestry by a process of natural selection, and in its proofs of his unbroken development from the embryo to adult life, it embraces the growth and development of mind and all that mind connotes. In the words of Professor Huxley, “As there is an anatomy of the body, so there is an anatomy of the mind; the psychologist dissects mental phenomena into elementary states of consciousness, as the anatomist resolves limbs into tissues, and tissues into cells. The one traces the development of complex organs from simple rudiments; the other follows the building up of complex conceptions out of simpler constituents of thought. As the physiologist inquires into the way in which the so-called ‘functions’ of the body are performed, so the psychologist studies the so-called ‘faculties’ of the mind. Even a cursory attention to the ways and works of the lower animals suggests a comparative anatomy and physiology of the mind; and the doctrine of evolution presses for application as much in the one field as in the other.”[95]

Any coherent explanation of the operations of nature was impossible while man had no conception or knowledge of the interplay of its several parts. Now, by the doctrine of continuity, not only are present changes referred to unvarying causes, but the past is interpreted by the processes going on under our eyes. We can as easily calculate eclipses backward as forward; we can learn in present formations of the earth’s crust the history of the deposition of the most ancient strata; we read in a rounded granite pebble the story of epochs, the fire that fused its organic or inorganic particles, the water that rubbed and rolled it; we reconstruct from a few bones the ancestry of obscure forms, and find in the fragments the missing links that connect species now so varied. And the like method is applied to man in his tout ensemble. His development is not arbitrary; what he is is the expansion of germs of what he was.

Till these latter days he has, on the warrant of legends now of worth only as witnesses to his crude ideas, presumed on an isolated place in creation, and excepted his race from an inquiry made concerning every creature beneath him. The pride of birth has hindered his admission of lineal connection between the beliefs of cultured races and the beliefs of savages, and pseudo-scientific writers still confuse issues by assuming distinctions between races to whom spiritual truths have been revealed and races from whom these truths have been withheld. But the only tenable distinction to be drawn nowadays is between the scientific and pre-scientific age in the history of any given race.

In these times, when many run to and fro, and knowledge is increased, we forget how recent are the tremendous changes wrought by the science that—
