If we suppose Intelligence, with an organism answering in its characteristics merely to the properties of the ether, we have a being conforming very nearly, if not quite, to the notion the mystics had of the indwellers of the supersensual world. With bodies more dense than steel, though unamenable to earthly sight or touch, these creatures would see the fleshly forms as a shadowy garment, and a matter at large but as a film thinner than air which offered no bar to their passage. And, exempt from the laws of gravitation which hold prison bound the frame of clay, they might levitate at will, and with the swiftness of light transport themselves from planet to planet. From the sun’s flame they could take no harm and even the chill of absolute zero would leave their bodies unscathed.
