It may be urged by those who still cling to the old-fashioned fetish of a distinction between Spirit and Matter, that this explanation of predictions, oracles, and insight, is simply materialistic and utterly destructive of all the poetry, grandeur, and beauty which is associated with mysterious divination. But for those who believe with Maudsley, et sui generis, that all such distinctions are not seriously worth considering, and to him who can rise to the great philosophy now dawning on the world, there is perceptible in it something far more wonderful and poetical, beautiful and even awful, than ever was known to any occultist of old--for it is scientific and true. It is also true that man can now talk across the world and hear all sounds conveyed to him through the depths of ocean. He can catch these sounds and keep them for centuries. How long will it be before sights, scents, and tastes will be thus transferred, and the man sitting in London will see all things passing in Asia, or wherever it pleases him or an agent to turn a mirror on a view? It will be. [19] Or how long before the discovery of cheap and perfect aerial navigation will change all society and annihilate national distinctions? That, too, will be. These and a thousand stranger discoveries will during the ensuing century burst upon the world, changing it utterly. We go on as of old in our little petty narrow grooves, declaring that this will be, and that will never come to pass, and that this or that kind of hop-scotch lines, and tip-cat and marbles rules, are the eternal laws of humanity, and lo! all the while in his study some man whom you regard as a dreamer or dolt is preparing that which will be felt forever. One of these great discoveries, and that not the least, will be the development and mastery of memory and perception, attention, interest, and will in children, with the constructive faculty which stimulates the whole by means of easy gradual series of instructions. When this system shall be perfected, we shall advance to understanding, controlling, and disciplining the subtler and stranger powers of the brain, which now puzzle us as dreams, intuitions, poetic inspiration, and prophecy. But this prophecy comes not from it, nor from any vague guessing or hoping. It is based on facts and on years of careful study of a thousand children's minds, and from a conviction derived from calm observation, that the powers of the human mind are infinite and capable of being developed by science. And they will be!
