We entirely agree; but the question is whether this does not represent a later stage in the religion of prehistoric humanity. Must there not have been a prior stage in which a less concrete idea of supernatural powers obtained? What induced the supposition that the god performed “measured movements”? And what would have been thought to be the form of these movements? Mr Marett, in the first essay of the volume already referred to, brings forward incontrovertible arguments, as it seems to us, for believing that there was a stage in the mental and religious development of man in which he was not yet capable of other than a vague sense of the supernatural; in which he had not yet associated definite spirits or ghosts with what he conceived to be supernatural phenomena; but in which the sense of mystery and consequently of awe in face of these supernatural phenomena filled his heart. This is also dealt with in the fourth essay: “The Conception of Mana.” It is in this stage that we would locate the origin of the sacred dance, performed in imitation of what were the movements of supernatural powers, but powers of the vaguest kind; merely a something, unknown, mysterious, and therefore to be feared; but associate yourself with it, and already you are in an indefinable way in communion with it; you have in some sense made friends with it, which makes things safer. “Given the supernatural in any form there are always two things to note about it: firstly, that you are to be heedful in regard to it; secondly, that it has power[22].” So that what Réville says is true, but it must be referred to a later stage of religious development.
