TWO main schools of religious thinking exist in our midst at the present day: the school of humanists and the school of animists. This work is to some extent an attempt to reconcile them. It contains, I believe, the first extended effort that has yet been made to trace the genesis of the belief in a God from its earliest origin in the mind of primitive man up to its fullest development in advanced and etherealised Christian theology. My method is therefore constructive, not destructive. Instead of setting out to argue away or demolish a deep-seated and ancestral element in our complex nature, this book merely posits for itself the psychological question, “By what successive steps did men come to frame for themselves the conception of a deity?”—or, if the reader so prefers it, “How did we arrive at our knowledge of God?” It seeks provisionally to answer these profound and important questions by reference to the earliest beliefs of savages, past or present, and to the testimony of historical documents and ancient monuments. It does not concern itself at all with the validity or invalidity of the ideas in themselves; it does but endeavour to show how inevitable they were, and how man’s relation with the external universe was certain a priori to beget them as of necessity.

In so vast a synthesis, it would be absurd to pretend at the present day that one approached one’s subject entirely de novo. Every enquirer must needs depend much upon the various researches of his predecessors in various parts of his field of enquiry. The problem before us divides itself into three main portions: first, how did men come to believe in many gods—the origin of polytheism; second, how, by elimination of most of these gods, did certain races of men come to believe in one single supreme and omnipotent God—the origin of monotheism; third how, having arrived at that concept, did the most advanced races and civilisations come to conceive of that God as Triune, and to identify one of his Persons with a particular divine and human incarnation—the origin of Christianity. In considering each of these three main problems I have been greatly guided and assisted by three previous enquirers or sets of enquirers.

As to the origin of polytheism, I have adopted in the main Mr. Herbert Spencer’s remarkable ghost theory, though with certain important modifications and additions. In this part of my work I have also been largely aided by materials derived from Mr. Duff Macdonald, the able author of Africana, from Mr. Turner, the well-known Samoan missionary, and from several other writers, supplemented as they are by my own researches among the works of explorers and ethnologists in general. On the whole, I have here accepted the theory which traces the origin of the belief in gods to primeval ancestor-worship, or rather corpse-worship, as against the rival theory which traces its origin to a supposed primitive animism.

As to the rise of monotheism, I have been influenced in no small degree by Kuenen and the Teutonic school of Old Testament criticism, whose ideas have been supplemented by later concepts derived from Professor Robertson Smith’s admirable work, The Religion of the Semites. But here, on the whole, the central explanation I have to offer is, I venture to think, new and original: the theory, good or bad, of the circumstances which led to the elevation of the ethnical Hebrew God, Jahweh, above all his rivals, and his final recognition as the only true and living god, is my own and no one else’s.

As to the origin of Christianity, and its relations to the preceding cults of corn and wine gods, I have been guided to a great extent by Mr. J. G. Frazer and Mannhardt, though I do not suppose that either the living or the dead anthropologist would wholly acquiesce in the use I have made of their splendid materials. Mr. Frazer, the author of that learned work, The Golden Bough, has profoundly influenced the opinions of all serious workers at anthropology and the science of religion, and I cannot too often acknowledge the deep obligations under which I lie to his profound and able treatises. At the same time, I have so transformed the material derived from him and from Dr. Robertson Smith as to have made it in many ways practically my own; and I have supplemented it by several new examples and ideas, suggested in the course of my own tolerably wide reading.

Throughout the book as a whole, I also owe a considerable debt to Dr. E. B. Tylor, from whom I have borrowed much valuable matter; to Mr. Sidney Hartland’s Legend of Perseus; to Mr. Lawrence Gomme, who has come nearer at times than anyone else to the special views and theories here promulgated; and to Mr. William Simpson of the Illustrated London News, an unobtrusive scholar whose excellent monographs on The Worship of Death and kindred subjects have never yet received the attention They deserve, at the hands of unprejudiced students of religion. My other obligations, to Dr. Mommsen, to my friends Mr. Edward Clodd, Professor John Rhys, and Professor York Powell, as well as to numerous travellers, missionaries, historians, and classicists, are too frequent to specify.

Looking at the subject broadly, I would presume to say once more that my general conclusions may be regarded as representing to some extent a reconciliation between the conflicting schools of humanists and animists, headed respectively by Mr. Spencer and Mr. Frazer, though with a leaning rather to the former than the latter.

At the same time it would be a great mistake to look upon my book as in any sense a mere eirenicon or compromise. On the contrary, it is in every part a new and personal work, containing, whatever its value, a fresh and original synthesis of the subject. I would venture to point out as especially novel the two following points: the complete demarcation of religion from mythology, as practice from mere explanatory gloss or guesswork; and the important share assigned in the genesis of most existing religious systems to the deliberate manufacture of gods by killing. This doctrine of the manufactured god, to which nearly half my book is devoted, seems to me to be a notion of cardinal value. Among other new ideas of secondary rank, I would be bold enough to enumerate the following: the establishment of three successive stages in the conception of the Life of the Dead, which might be summed up as Corpse-worship, Ghost-worship, and Shade-worship, and which answer to the three stages of preservation or mummification, burial, and cremation; the recognition of the high place to be assigned to the safe-keeping of the oracular head in the growth of idol-worship; the importance attached to the sacred stone, the sacred stake, and the sacred tree, and the provisional proof of their close connection with the graves of the dead; the entirely new conception of the development of monotheism among the Jews from the exclusive cult of the jealous god; the hypothesis of the origin of cultivation from tumulus-offerings, and its connection with the growth of gods of cultivation; the wide expansion given to the ancient notion of the divine-human victim; the recognition of the world-wide prevalence of the five-day festival of the corn or wine god, and of the close similarity which marks its rites throughout all the continents, including America; the suggested evolution of the god-eating sacraments of lower religions from the cannibal practice of honorifically eating one’s dead relations; * and the evidence of the wide survival of primitive corpse-worship down to our own times in civilised Europe. I could largely increase this rapid list of what I believe to be the new contributions here made to the philosophy of religious evolution; but I purposely refrain. I think it will be allowed that if even a few of these ideas turn out on examination to be both new and true, my book will have succeeded in justifying its existence.

I put forth this work with the utmost diffidence. The harvest is vast and the labourers are few. I have been engaged upon collecting and comparing materials for more than twenty years. I have been engaged in writing my book for more than ten. As I explain in the last chapter, the present first sketch of the conclusions at which I have at last arrived is little more than provisional. I desire in my present essay merely to lay down the lines of the general theory which after so many years of study I incline to accept. If my attempt succeeds in attracting public attention, I hope to follow it up by several other volumes in which the main opinions or suggestions here set forth may be reinforced and expanded by copious collections of evidence and illustrations. If it fails to arouse public attention, however, I must perforce be satisfied with this very inadequate preliminary statement. I should also like to add here, what I point out at greater length in the body of the work, that I do not hold dogmatically to all or to a single one of the ideas I have now expressed. They are merely conceptions forced upon my mind by the present state of the evidence; and I recognise the fact that in so vast and varied a province, where almost encyclopaedic knowledge would be necessary in order to enable one to reach a decided conclusion, every single one or all together of these conceptions are liable to be upset by further research. I merely say, “This is how the matter figures itself to me at present, on the strength of the facts now and here known to us.”

A few chapters of the book were separately published in various reviews at the time they were first written. They were composed, however, from the outset, as parts of this book, which does not therefore consist of disconnected essays thrown into line in an artificial unity. Each occupies the precise place in the argument for which it was first intended. The chapters in question are those on “Religion and Mythology,” and “The Life of the Dead,” contributed under the titles of “Practical Religion” and “Immortality and Resurrection” to the Fortnightly Re-view; that on “Sacred Stones,” contributed under the same name to the same periodical; and that on “The Gods of Egypt,” which originally appeared in the Universal Review. I have to thank the proprietors and editors of those magazines for permission to print them in their proper place here. They have all been altered and brought up as far as I could bring them to the existing state of our knowledge with regard to the subjects of which they treat.

In dealing with so large a variety of materials, drawn from all times and places, races and languages, it would be well-nigh impossible to avoid errors. Such as my own care could discover I have of course corrected: for the rest, I must ask on this ground the indulgence of those who may happen to note them.

I have endeavoured to write without favour or prejudice, animated by a single desire to discover the truth. Whether I have succeeded in that attempt or not, I trust my book may be received in the same spirit in which it has been written,—a spirit of earnest anxiety to learn all that can be learnt by enquiry and investigation of man’s connection with his God, in the past and the present. In this hope I commit it to the kindly consideration of that small section of the reading public which takes a living interest in religious questions.
