a. REST, CENTRE.
209. Through light duplicity originates in the æther, by virtue of which the æther divides into central and peripheric æther. The peripheric necessarily rotates around the central. Every part of the æther is a sphere; the æther therefore is separated by the light into infinitely numerous central and peripheric spheres. Creation is an endless position of centres. The primary centre is inventive.
210. There cannot be therefore only a single central mass; otherwise the universe would be a finite.
211. The central spheres are characterized by absoluteness, the peripheric, however, by finiteness, division; the former are something in themselves, but the latter are so only by opposition; yet the two could not be without each other.
212. Every central body must be surrounded by several peripheric bodies. The peripheric spheres rotate around the central, the images of the primary centre. A Whole, consisting of a central body and several peripheric bodies, is called solar system.
213. Chaos is not conceivable, without being at the same time solar system. The solar systems are nothing specially created, but have been given with chaos or with light, are indeed only the æther separated by light. The primary matter appearing as light must appear at the same time as sun and planet. Primary act, sun and planet are of one kind, and differ only in this, that the former is posited individually in the latter, while in itself it is non-posited.
214. There is no general central body, no central sun, about which all suns and planets gravitate. The essence of the æther consists in its complete dissipation. There exists only an infinity of solar systems, which taken together form the central body. All solar systems pursue a course to and fro through each other, like the blood-globules in the vessels. The general central body is only inventive. That the general central body may be dark (that it must be, if present, from its being invisible) is an assertion which betrays an ignorance of the essence of light. A dark central body is an absurdity.
b. MOTION, LINE.
215. Sun and planet, as individual spheres, have also their own individual gravity. The æther therefore must exist otherwise than in the universal sphere. The next change of the æther is condensation, more intense gravity, because it becomes more individual, centre and periphery approximate more closely to each other. The heavenly bodies must contain more matter, more æther in an equal space than the terrestrial globe.
216. The heavenly bodies have obtained their matter nowhere else than out of the primary matter, the æther; they are condensed æther. The heavenly bodies of a solar system have derived their mass out of the æther, which is found within the confines of this solar system. The matter of the heavenly bodies was thus previous to its coagulation strewn in the space of the solar system, and has been by so much the rarer, as the space of the solar system is larger than the volume of all the planets together with the sun. It admits therefore of being calculated how much rarer the æther is than e. g. water.
