In order to recognize the peculiar function of the I in man, we must first be clear as to how he differs from the other kingdoms of nature, and how they differ from one another with respect to the mode of action of the physical, etheric and astral forces.

c21p5

The beings of all the kingdoms of nature are endowed with an aggregate of physical forces in the form of a material body subject to gravity. The same cannot be said of the etheric forces. Only where life is present as an inherent principle – that is, in plant, animal and man – is ether at work in the form of an individual etheric organization, while the mineral is formed by the universal ether from outside. Where life prevails, we are met by the phenomena of birth and death. When a living organism comes to birth, an individual ether-body is formed out of the general etheric substance of the universe.1 The death of such an organism consists in the separation of the etheric from the physical body and the dissolution of both in their respective mother-realms. So long as an organism is alive, its form is maintained by the ether-body present in it.

Our studies have shown that the plant is not devoid of the operation of astral forces. In the plant’s life-cycle this comes to clearest expression in its florescence. But it is a working of the astral forces from outside, very much as the ether works on the mineral. As a symptom of this fact we may recall the dependence of the plant on the various outer astronomical rhythms.

It will be our task to analyse the Kepler-Newton case on the very lines of our treatment of the two parallelogram theorems. This analysis will give us insight into a truth which we have to regard as one of the basic maxims of the new science. It says that whether a given formula, derived mathematically from one that was first read from nature, still expresses some fact of nature, cannot be decided by pure mathematical logic, but only by testing it against truly observable phenomena.

It is only in animal and man that we find the astral forces working in the form of separate astral bodies. This accounts for their capacity for sensation and volition. Besides the alternation of birth and death, they experience the rhythm of sleeping and waking. Sleep occurs when the astral body leaves the physical and etheric bodies in order to expand into its planetary mother-sphere, whence it gathers new energy. During this time its action on the physical-etheric aggregate remaining upon earth is similar to that of the astral cosmos upon the plant.
