This view, if pushed back far enough, is no doubt inconsistent with the way in which evolution is generally conceived. For it denies that all human faculties must have been evoked by terrene experience. It assumes a subliminal self, with unknown faculties, originated in some unknown way, and not merely by contact with the needs which the terrene organism has had to meet. It thus seems at first sight to be introducing a new mystery, and to be introducing it in a gratuitous way. To this I reply in the first place that so far as the origin of man's known powers is concerned, no fresh mystery is in fact introduced. All human powers, to put the thing broadly, have somehow or other to be got into protoplasm and then got out again. You have to explain first how they became implicit in the earliest and lowest living thing, and then how they have become thus far explicit in the latest and highest. All the faculties of that highest being, I repeat, existed _virtually_ in the lowest, and in so far as the admitted faculties are concerned, the difference between my view and the ordinary view may be said to be little more than a difference as to the sense which that word _virtually_ is here to assume. The real difference between the two views appears when the faculties which I have called unknown come to be considered. If they are held to be real, my view is certainly the better able to embrace them. I hold that telepathy and telæsthesia do in fact exist--telepathy, a communication between incarnate mind and incarnate mind, and perhaps between incarnate minds and minds unembodied; telæsthesia, a knowledge of things terrene which overpasses the limits of ordinary perception, and which perhaps also achieves an insight into some other than terrene world. And these faculties, I say, cannot have been acquired by natural selection, for the preservation of the race, during the process of terrene evolution; they were (as we may phrase it) the products of extra-terrene evolution. And if they were so, man's other powers may well have been so also. The specialised forms of terrene perception were not real novelties in the universe, but imperfect adaptations of protoplasm to the manifestation of the indwelling general perceptive power. The mathematical faculty, for instance (we may, perhaps, say with Plato), pre-existed. When Dase solved all those sums in his head, his power of solving them was not a fresh development in his ancestral stock, but depended on the accidental adaptation of his organism to the manifestation of the indwelling computative power. I do not indeed venture to follow Plato in his ontogenetic argument--his claim that the individual computator has had already an individual training in computation. I do not say that Dase himself learnt or divined the multiplication-table in some ideal world. I only say that Dase and all the rest of us are the spawn or output of some unseen world in which the multiplication-table is, so to speak, in the air.
