The continuity of the phenomena is, indeed, of profound significance, and is too often ignored. It is often asserted that we have to explain the lower by the higher, and we can only understand the significance of religion in its lower forms by bearing in mind the higher manifestations. This is sheer fallacy. In nature the higher develops out of the lower, of which it is compounded. In biology, for example, it is now generally conceded that the secret of animal life lies in the cell. This may be modified in all kinds of directions, the resulting organic structure may be of the utmost complexity, but the basis remains unchanged. So, too, with a great deal of so-called religious phenomena. The story is not only continuous, but the same elements remain unchanged with only those modifications initiated by a changed environment. And just as we are driven back to the cell to explain organic structure, so for an understanding of the phenomena under consideration we must study their primitive elements. Analysis must precede synthesis here as elsewhere. A survey of the subject is not at all exhausted by a study of abnormal conditions, so far as these have entered into the life of religion. There still remains the study of perfectly normal frames of mind that are misinterpreted and diverted into religious channels. The importance of this will be seen more clearly when we come to deal with the subject of conversion. That "conversion" is a phenomenon of adolescence is now settled beyond all reasonable doubt. Statistics are conclusive on this point. But the advocate of revivalism quite misses the true significance of the fact. Current religious literature is full of quite meaningless chatter concerning the change of view, the larger and more unselfish activities, that arise as a consequence of conversion. There is really no evidence that the changes indicated have any connection with conversion. All that does happen can be more simply and more adequately explained as resulting from physiological and psychological changes in terms of racial and social evolution. The whole significance of adolescence lies in the bursting into activity of feelings hitherto dormant, and the quickening of a desire for communion with a larger social life. The individual becomes less self-centred, more alive to, and more responsive to the claims of others; he displays tendencies towards what the world calls self-sacrifice, but which mean, in the truest sense, self-realisation. That these changes are often expressed in terms of religion is undeniable. This, however, may be no more than an environmental accident, quite as much so as was the case when epilepsy was explained in terms of possession.
