That the science of religion at the end leaves untouched those differences between religions which it recognised at the beginning, is a point on which I insisted, as against those who unwarrantably proclaim the science to have demonstrated that all religions alike are barbarisms or survivals of barbarism. It is well, therefore, to bear that fact in mind when attempts are made to explain the existence of the differences by postulating a period when they were non-existent. That postulate may take form in the supposition that originally the true religion alone existed, and that the differences arose later. That is a supposition which has been made by more than one people, and in more ages than one. It carries with it the consequence that the history—it would be difficult to call it the evolution and impossible to call it the progress—of religion has been one of degradation generally. Owing, however, to the far-reaching and deep-penetrating influence of the theory of evolution, it has of late grown customary to assume that the movement, the course of religious history, has been in the opposite direction; and that it has moved upwards from the lowest forms of religion known to us, or from some form analogous to the lowest known forms, through the higher to the highest. This second theory, however different in its arrangement of the facts from the Golden Age theory first alluded to, is still fundamentally in agreement with it, inasmuch as it also assumes that the differences exhibited later in the history of religion at first were non-existent. Both theories assume the existence of the originally homogeneous, but they disagree as to the nature of the differences which supervened, and also as to the nature of the originally homogeneous.

I wish therefore to call attention to the simple truth that the facts at the disposal of the science of religion neither enable nor warrant us to decide between these two views. If we were to come to a decision on the point, we should have to travel far beyond the confines of the science of religion, or the widest bounds of the theory of evolution, and enquire why there should be error as well as truth—or, to put the matter very differently, why there should be truth at all. But if we started travelling on that enquiry, we should not get back in time for this course of lectures. Fortunately it is not necessary to take a ticket for that journey—perhaps not possible to secure a return ticket. We have only to recognise that the science of religion confines itself to constating and tracing the differences, and does not attempt to explain why they should exist; while the applied science of religion is concerned with the practical business of bringing home the difference between Christianity and other forms of religion to the hearts of those whose salvation may turn on whether the missionary has been properly equipped for his task.

If, now, I announce that for the student of the applied science it is advisable that he should turn his attention in the first place to the lowest forms of religion, the announcement need not be taken to mean that a man cannot become a student of the science of religion, whether pure or applied, unless he assumes that the lowest is the most primitive form. The science of religion, as it pushes its enquiries, may possibly come across—may even already have come across—the lowest form to which it is possible for man to descend. But whether that form is the most primitive as well as the lowest,—still more, whether it is the most primitive because it is the lowest,—will be questions which will not admit of being settled offhand. And in the meantime we are not called upon to answer them in the affirmative as a sine qua non of being admitted students of the science.

The reason for beginning with the lowest forms is—as is proper in a practical science—a practical one. As I have already said, if the missionary is to succeed in his work, he must know and teach the difference and the value of the difference between Christianity and other religions. But difference implies similarity: we cannot specify the points of difference between two things without presupposing some similarity between them,—at any rate sufficient similarity to make a comparison of them profitable. Now, the similarity between the higher forms of religion is such that there is no need to demonstrate it, in order to justify our proceeding to dwell upon the differences. But the similarity between the higher and the lower forms is far from being thus obvious. Indeed, in some cases, for example in the case of some Australian tribes, there is alleged, by some students of the science of religion, to be such a total absence of similarity that we are entitled or compelled to recognise that however liberally, or loosely, we relax our definition of religion, we must pronounce those tribes to be without religion. The allegation thus made, the question thus raised, evidently is of practical importance for the practical purposes of the missionary. Where some resemblances exist between the higher and the lower forms of religion, those resemblances may be made, and should be made, the ground from which the missionary should proceed to point out by contrast the differences, and so to set forth the higher value of Christianity. But if no such resemblances should exist, they cannot be made a basis for the missionary's work. Without proceeding in this introductory lecture to discuss the question whether there are any tribes whatever that are without religion, I may point out that religion, in all its forms, is, in one of its aspects, a yearning and aspiration after God, a search after Him, peradventure we may find Him. And if it be alleged that in some cases there is no search after Him,—that amongst civilised men, amongst our own acquaintances, there is in some cases no search and no aspiration, and that therefore among the more backward peoples of the earth there may also be tribes to whom the very idea of such a search is unknown,—then we must bear in mind that a search, after any object whatever, may be dropped, may even be totally abandoned; and yet the heart may yearn after that which it is persuaded—or, it may be, is deluded into thinking—it can never find. Perhaps, however, that way of putting it may be objected to, on the ground that it is a petitio principii and assumes the very fact it is necessary to prove, viz. that the lowest tribes that are or can be known to us have made the search and given it up, whereas the contention is that they have never made the search. That contention, I will remark in passing, is one which never can be proved. But to those who consider that it is probable in itself, and that it is a necessary stage in the evolution of belief, I would point out that every search is made in hope—or, it may be, in fear—that search presupposes hope and fear. Vague, of course, the hope may be; scarce conscious, if conscious at all, of what is hoped. But without hope, until there are some dim stirrings, however vague, search is unconceivable, and it is in and by the process of search that the hope becomes stronger and the object sought more definite to view. Now, inasmuch as it is doubtful whether any tribe of people is without religion, it may reasonably be held that the vast majority, at any rate, of the peoples of the earth have proceeded from hope to aspiration and to search; and if there should be found a tribe which had not yet entered consciously on the search, the reasonable conclusion would be not that it is exempted from the laws which we see exemplified in all other peoples, but that it is tending to obey the same laws and is starting from the same point as they,—that hope which is the desire of all nations and has been made manifest in the Son of Man.

Whatever be the earliest history of that hope, whatever was its nature and course in prehistoric times, it has been worked out in history in many directions, under the influence of many errors, into many forms of religion. But in them all we feel that there is the same striving, the same yearning; and we see it with the same pity and distress as we may observe the distorted motions of the man who, though partially paralysed, yet strives to walk, and move to the place where he would be. It is with these attempts to walk, in the hope of giving help to them who need it, that we who are here to-day are concerned. We must study them, if we are to understand them and to remedy them. And there is no understanding them, unless we recognise that in them all there is the striving and yearning after God, which may be cruelly distorted, but is always there.

It so happens that there has been great readiness on the part of students of the science of religion to recognise that belief in the continued existence of the soul after the death of the body has comparative universality amongst the lower races of mankind. Their yearning after continued existence developes into hope of a future life; and the hope, or fear, takes many forms: the continued existence may or may not be on this earth; it may or may not take the shape of a belief in the transmigration of souls; it sometimes does, and sometimes does not, lead to belief in the judgment of the dead and future punishments and rewards; it may or may not postulate the immortality of the soul; it may shrink to comparative, if not absolute, unimportance; or it may be dreaded and denounced by philosophy and even by religion. But whether dreaded or delighted in, whether developed by religion or denounced, the tendency to the belief is there—universal among mankind and ineradicable.

The parallel, then, between this belief and the belief or tendency to believe in God is close and instructive; and I shall devote my next lecture therefore to the belief in a future life among the primitive races of mankind. That belief manifests itself, as I shall hope to show, from the beginning, in a yearning hope for the continued existence of the beloved ones who have been taken from us by death, as well as in dread of the ghosts of those who during their life were feared. But in either case what it postulates and points to is man living in community with man. It implies society; and there again is parallel to religion. It is with the hopes and fears of the community as such that religion has to do: and it is from that point of view that I shall start when I come to deal with the subject of magic, and its resemblance to and difference from religion. Its resemblance is not accidental and the difference is not arbitrary: the difference is that between social and anti-social purposes. That difference, if borne in mind, may give us the clue to the real nature of fetichism,—a subject which will require a lecture to itself. I shall then proceed to a topic which has been ignored to a surprising extent by the science of religion; that is, the subject of prayer: and the light which is to be derived thence will, I trust, give fresh illumination to the meaning of sacrifice. The relation of religion to morality will then fall to be considered; and my final lecture will deal with the place of Christianity in the evolution of religion.
