Now the business of science is to collect facts—all

facts—classify them, and frame generalisations that will explain their groupings and modes of operation. It talks of the facts of the physical world, the facts of the biological world, the facts of the psychological world, and so forth. This last group comprises all sorts of feelings and ideas, beliefs and experiences. Some of these facts it calls false, others it calls true—that is, they are true when they hold good of all men and women normally constituted, they are not true when they hold good of isolated individuals only, and can be seen to be the product of misinterpreted experience, or arise from a derangement—permanent or temporary—of the nervous system. But true or false they remain facts of the mental life. They must be collected, grouped, and explained exactly as other facts are collected, grouped, and explained. They fall within the scope of science, to be dealt with by scientific methods.

There is really no escape from the position that so far as religious 'facts' are parts of mental life, religion becomes logically a department of psychology. The substantial identity of all mental facts is quite unaffected by their being directed to this or that special object. As mental facts they are part of the material that it is the work of science to reduce to order. And as mental facts religious phenomena are seen to follow the same 'laws' that govern mental phenomena in general. It is perfectly true that we cannot test and measure the material of psychology with the same definiteness and accuracy that the chemist applies to the subject-matter of his department; but that may be due to want of knowledge, or to the extreme complexity and variability of the matter with which we are dealing. And

if it were true that the same tests could not be applied in psychology that are applied elsewhere, this would be no cause for scientific despair. It would only mean that fresh tests would have to be devised for a new group of facts, as every other science has already, as a matter of fact, created its own special standard of value.

The second of the two lines of defence consists in the bold assertion that the religious interpretation of subjective phenomena is itself in the nature of a true scientific induction. The methods of science are not repudiated, but welcomed. But it is argued that the non-religious explanation of religious phenomena breaks down hopelessly, while the religious explanation fully covers and explains the facts. If this were true, nothing more remains to be said, and we must accept this dualistic scheme, however repugnant it may be to orthodox scientific ideas. But is it true? Is it a fact that the non-religious explanation breaks down so completely? Hitherto the course of events has been in the contrary direction. It is the religious explanation that has, over and over again, been shown to be unreliable, the non-religious explanation that has been finally established. Insanity and epilepsy, once universally ascribed to a supernatural order of being, have been reduced to the level of nervous disorders. All the phenomena of 'possession' are still with us, it is only our understanding of them that has altered. And before it is admitted that the phenomena described as religious can never be affiliated to the phenomena described as non-religious, it must be shown—beyond all possibility of doubt—that their explanation in terms of known forces is impossible. As I have said in the body of this work, the question at issue is essentially one of

interpretation. The 'facts' of the religious life are admitted. Science no more questions the reality of the visions of the medieval mystic than it questions the visions of the non-mystic admittedly suffering from neural derangement. The crucial question is whether we have any good reason for separating the two, and while we dismiss the one as hallucination accept the other as introducing us to another order of being? I do not think there is the slightest ground for any such differentiation, and I have given in the following pages what I conceive to be good reasons for so thinking. And I hope that the fact of the explanations there offered running counter to the traditional one will not prevent readers weighing with the utmost care the proofs that are offered.

RELIGION AND SEX
CHAPTER ONE
SCIENCE AND THE SUPERNATURAL

Accepting Professor Tylor's famous minimum definition of religion as "the belief in Spiritual Beings," it is safe to say that religious belief constitutes one of the largest facts in human history. No other single subject has occupied so large a share of man's conscious life, no other subject has absorbed so much of his energy. In very early stages of culture religious belief is universal in the fullest sense of the word. It shapes all primitive institutions; it dominates life from the cradle to the grave, and creates a shadow-land beyond the grave from which the dead continue to influence the actions of the living. At a later stage of culture we see a distinction being drawn between the natural and the supernatural, the secular and the spiritual, and the beginning of an antagonism that is still with us. Of all antagonisms conceived by the brain of man this is the deepest and the most irreconcilable. Each feels that the growth of the other threatens its own supremacy, with the result that advance from either side has been contested with the greatest obstinacy and determination. And although it is true that at present the supernatural is very largely "suspect," it is still powerful. Nor is its influence confined to the lower strata of European society. It has very many representatives among the higher culture, disguised it may be under various pseudo-philosophic forms. Altogether we may say that the supernatural has never been without its "cloud of witnesses." At all times there have been individuals,

or groups of individuals, who have believed themselves, and have been believed by others, to be in touch with another order of existence than that with which people are normally in contact. And apart from these specially favoured persons, the wide vogue of the belief in good and evil portents, in lucky and unlucky days, the attraction of the "occult" in fiction and in fact, all serve as evidence that belief in the supernatural is still a force with which one has to reckon.
