Firstly, by the way we have spoken of the varying relations of the sun and moon to the earth, seeing in them the effects of certain astral activities, we have treated them as if they were of like nature, namely, resulting from a movement of the relevant heavenly body round the earth. According to the Copernican conception, however, only the moon rotates round the earth, whereas the apparent yearly progression of the sun is actually caused by the earth’s motion round the sun. This raises the question of how far the Copernican, heliocentric aspect is valid in a science which strives to embrace the astral realm of the universe in its inquiries.

Thirdly, if it is true that the essential solar and lunar effects – and presumably the effects of the other planets – on the earth do not spring from physical influence exerted by the visible bodies of the planets concerned, but from certain astral force-fields of which these bodies themselves form part, what is the significance of such a body within the planet’s dynamic whole?

Starting with the answer to the first question, we shall quote the following passage from a lecture on theoretical physics given by Professor Planck in 1909 at the Columbia University, New York:

‘Only the hypothesis of the general value of the principle of Relativity in mechanics could admit the Copernican system into physics, since this principle guarantees the independence of all processes on the earth from the progressive motion of the earth. For, if we had to make allowance for this motion, then I should, for instance, have to reckon with the fact that the piece of chalk in my hand possesses the enormous kinetic energy corresponding to a velocity of about 30 km/sec.’

In a science which knows how to deal with movement as an event of absolute dynamic reality, the Copernican aspect loses its significance as the only valid aspect of our cosmic system. For its application as a means of describing the dynamic happenings within this system presupposes the acceptance of Einstein’s relativistic conception of motion. Indeed, for the building up of a picture of the dynamic structure of our system, the Copernican view-point is inadequate.

This statement must not be taken to deny all justification to the heliocentric view-point. There is, after all, the fact that the orbits which the heavenly bodies appear to follow when viewed in this way, assume a particular geometrical character which cannot be accidental. And more than that, when the heliocentric aspect is seen in its true setting, it forms (as will be shown later) an extremely revealing part of the script which tells us of the nature of the astral forces. All that is required is that the heliocentric picture be taken for what it is, namely, a purely kinematic aspect of the true dynamic ordering of our cosmic system, which in itself calls for quite other means of conceptual representation.

From the point of view of the astral order of the universe, the earth appears in the centre of a number of force-fields which penetrate each other and in their peripheral region extend beyond one another in accordance with the respective orbits of the various planetary bodies. How many force-fields there are, and what is the respective character of each, will become clear from the following consideration, which will also provide the answer to the second of our three questions.

As the originator of the secondary polarities in earthly nature the astral realm must undoubtedly itself be structured polarically, one part of it forming the cause of all the happenings by which levity is brought into interaction with gravity, the other of all the happenings by which gravity is brought into interaction with levity. There must be a further part which is responsible for the establishment of the ‘mercurial’ mean between the two poles of the secondary polarity. This leads us to a threefold aspect of the astral realm.

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.
