IV. Body, Soul and Spirit

The mineral forces are perceived by man by means of his bodily senses; and he can only perceive that for which he has such senses. Without the eye there is no perception of light, without the ear no perception of sound. The lowest organisms have only one of the senses belonging to man: a kind of sense of touch. Nothing can be perceived by such organisms, in the way a human being perceives, except those mineral forces which make themselves known through the sense of touch. In proportion as the other senses are developed in the higher animals does their surrounding world, which man also perceives, become richer and more varied. It depends, therefore, on the organs of a being whether that which exists in the outer world exists also for the being itself, as perception, as sensation. What is present in the air as a certain motion becomes in man the sensation of hearing. Man does not perceive the manifestations of the life-force through the ordinary senses. He sees the colours of the plants; he smells their perfume; the life-force remains hidden from this form of observation. But the ordinary senses have just as little right to deny that there is a life-force as has the man born blind to deny that colours exist. Colours are there for the person born blind as soon as he has been operated upon; in the same way, the objects, the various species of plants and animals created by the life-force (not merely the individual plants and animals) are present to man as objects of perception as soon as the necessary organ unfolds within him. An entirely new world opens out to man through the unfolding of this organ. He now perceives, not merely the colours, the odours, etc., of the living beings, but the life itself of these beings. In each plant, in each animal, he perceives, besides the physical form, the life-filled spirit-form. In order to have a name for this spirit-form let it be called the ether-body, or life-body.[^1]
