II. Introductory Explanations Concerning the Nature of Man

Spiritual science therefore says: A living being would decay into the component parts of its substances if it were left to itself, if within it there did not exist something which prevents this decay. That which every moment prevents this living being from decaying, the preventing factor of such a decay, is what we call the etheric or the vital body. This is of an entirely different nature from the substances which constitute the physical body in every living being, and it has the capacity to produce the most complicated physical substances, to maintain them and to prevent their decay. What a living organism thus reveals in a purely external form, is what we call LIFE. This etheric or vital body, or this body of formative forces, cannot be perceived by physical eyes, but it can be perceived through the first degree of clairvoyant vision, and it is the task of a clairvoyant to develop himself so as to be able to perceive this etheric body. Modern natural science does indeed try to discover the etheric body, but it tries to form a conception of it in a purely speculative way, by speaking, for instance of vital force, or vital energy.
