We may admit that certain of their theories are rather ingenious; and what they say of the part played by the “shells,” for instance, or the “elementals,” in the spiritualistic phenomena, is worth about as much as our clumsy explanations of fluidic and supersensible bodies. Perhaps, or even no doubt, they are right when they insist that everything around us is full of living, sentient forms, of diverse and innumerous types, “as different from one another as a blade of grass and a tiger, or a tiger and a man,” which are incessantly brushing against us and through which we pass unawares. If all the religions have overpopulated the world with invisible beings, we have perhaps depopulated it too completely; and it is extremely possible that we shall find one day that the mistake was not on the side which one imagines. As Sir William Crookes so well puts it, in a remarkable passage:
“It is not improbable that other sentient beings have organs of sense which do not respond to some or any of the rays to which our eyes are sensitive, but are able to appreciate other vibrations to which we are blind. Such beings would practically be living in a different world to our own. Imagine, for instance, what idea we should form of surrounding objects were we endowed with eyes not sensitive to the ordinary rays of light but sensitive to the vibrations concerned in electric and magnetic phenomena. Glass and crystal would be among the most opaque of bodies. Metals would be more or less transparent, and a telegraph wire through the air would look like a long narrow hole drilled through an impervious solid body. A dynamo in active work would resemble a conflagration, whilst a permanent magnet would realise the dream of mediaeval mystics and become an everlasting lamp with no expenditure of energy or consumption of fuel.”
All this, with so many other things which they assert, would be, if not admissible, at least worthy of attention, if those suppositions were offered for what they are, that is to say, very ancient hypotheses that go back to the early ages of human theology and metaphysics; but, when they are transformed into categorical and dogmatic assertions, they at once become untenable. Their exponents promise us, on the other hand, that, by exercising our minds, by refining our senses, by etherealizing our bodies, we shall be able to live with those whom we call dead and with the higher beings that surround us. It all seems to lead to nothing very much and rests on very frail bases, on very vague proofs derived from hypnotic sleep, presentiments, mediumism, phantasms and so forth. It is rather surprising that those who call themselves “clairvoyants,” who pretend to be in communication with this world of discarnate spirits and with other worlds still nearer to the divine, bring us no evidential proofs. We want something more than arbitrary theories about the “immortal triad,” the “three worlds,” the “astral body,” the “permanent atom,” or the “Karma-Loka.” As their sensibility is keener, their perception subtler, their spiritual intuition more penetrating than ours, why do they not choose as a field for investigation the phenomena of prenatal memory, for instance, to take one subject at random from a multitude of others, phenomena which, although sporadic and open to question, are still admissible? We are only too eager to allow ourselves to be convinced, for all that adds anything to man’s importance, range or duration must needs be gladly welcomed.[[3]]
