For the same reason Goethe knew it would be historically unjustified to expect that Kepler could have conceived an aspect of the universe implicit in his own conception of nature. Hence it did not disturb him in his admiration for Kepler, that through him the Copernican aspect of the universe had become finally established in the modern mind – that is, an aspect which, as we have seen, is invalid as a means of forming a truly dynamic conception of the world.

To see this, let us choose the periods of two definite planets – say, Earth and Jupiter. For these the equation assumes the following form (‘J’ and ‘E’ indicating ‘Jupiter’ and ‘Earth’ respectively):
rJ3 / rE3 = (tJ / tE) / (tE / tJ)
Let us now see what meaning we can attach to the two expressions
tJ / tE and tE / tJ.

What we have now brought to our awareness by studying man, holds good in some sense also for the animal. The animal, too, is polarized into motion and sensation. (What makes the animal differ from man need not concern us here, for it belongs to a dynamic realm other than the one we are now studying. This other realm will come under consideration in the next chapter.) Quite a different picture arises when we turn to the plant. The plant, too, is characterized by a threefold structure, root, stem with leaves, and florescence, which in their way represent the three alchemical functions. Consequently, there is also motion in the plant, although this is confined to internal movements leading to growth and formation. And at the opposite pole there is sensation, though again very different from the sensation experienced by higher living beings. What we mean here by ‘sensation’ can be best expressed by quoting the following passage from Ruskin’s The Queen of the Air, in which the dual activity of the dynamic which we seek to understand is brought out particularly clearly.

What strikes us first in this respect is the plant’s dependence on the succession of the seasons. These in turn are an outcome of the changing mutual positions of earth and sun. That which forms part of the individual organism in higher living beings is located in the cosmic surroundings of the plant. In fact, it is our planetary system which provides the forces that stir the etheric and physical forces of the earth to their various interactions, thus bringing about all the manifold secondary polarities.

Closer inspection reveals a repetition of this threefold order within each of the two polar regions. In Chapter XII we learnt to distinguish the material happenings at the two poles of the secondary polarity by observing their appearance in the plant as ‘sublimation’, on the one hand, and ‘assimilation’ on the other. Of the former process, by which matter is carried from its gravity-bound to its gravity-free condition, we know that it takes place in three stages, of which the first implies the lifting of matter from the solid to the liquid condition, the second from the liquid to the aeriform condition, and the third to the condition of pure heat. There are three corresponding stages by which ether becomes susceptible to gravity. It is in their nature that they are not in the same degree manifest as are their polar opposites. Still, properly guided observation is able to detect them and enables us to describe them as follows. At the first stage, ether, which in itself has a purely peripheral orientation, becomes linked to some all-relating point; at the second stage, the various ether-activities, already point-related, are brought into some characteristic interrelationship so as to become the cause of a particular formative action in the material realm; at the third stage, the etheric aggregate thus organized receives the impulse to link itself with some particular portion of ponderable matter.

In consequence, the science of acoustics became for the scientific mind of man a model of the required division between the ‘subjective’ (that is, for scientific considerations non-existent) and the ‘objective’ (that is, the purely kinematic) part of observation. The field of aural perception seemed to justify the procedure of collecting a mass of phenomena, stripped of all that is experienced by man’s soul in meeting them, and of assembling them under a purely abstract concept, ‘sound’.

In order to understand how the muscles respond to the outer astral impulses which reach us through our ear, we must first understand what happens in the muscles when our will makes use of them for bodily motion. In this case, too, the muscular system is the organ through which certain astral impulses, this time arising out of the body’s own astral member, come to expression. Moreover, the movement of the muscles, though not outwardly perceptible, is quite similar to acoustic movements outside the body. For whenever a muscle is caused to alter its length, it will perform some kind of vibration – a vibration characterized even by a definite pitch, which differs in different people. Since throughout life our body is never entirely without movement, we are thus in a constant state of inward sounding. The muscular system is capable of this vibration because during the body’s initial period of growth the bones increase in length to a much greater extent than do the sinews and muscles. Hence the latter arrive at a condition of elastic tension not unlike that of the strings of a musical instrument.10

In forming his picture of the universe, it is true, Copernicus was concerned with nothing but the spatial movements of the luminous entities discernible in the sky, without any regard to their actual nature and dynamic interrelationships. Hence his world-picture – as befits the spectator-form of human consciousness which was coming to birth in his own time – is a purely kinematic one. As such it has validity for a certain sphere of human observation.

During one rotation of Jupiter round the sun the earth circles 12 times round it. This we are wont to express by saying that Jupiter needs 12 earth-years for one rotation; in symbols:
tJ / tE = 12 / 1
To find the analogous expression for the reciprocal ratio:
tE / tJ = 1 / 12
we must obviously form the concept ‘Jupiter-year’, which covers one rotation of Jupiter, just as the concept ‘earth-year’ covers one rotation of the earth (always round the sun). Measured in this time-scale, the earth needs for one of her rotations 1 / 12 of a Jupiter-year.

In describing the forming of blossom in the plant as the climax of the ‘spirit’ active in it, Ruskin says: ‘Its (the plant’s) form becomes invested with aspects that are chiefly delightful to our own human passions; namely, first, with the loveliest outlines of shape and, secondly, with the most brilliant phases of the primary colours, blue, yellow, red or white, the unison of all; and to make it more strange, this time of peculiar and perfect glory is associated with relations of the plants or blossoms to each other, correspondent to the joy of love in human creatures and having the same object in the continuance of the race.’2
