50 ONTOLOGY. 



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 aether consists in its complete dissipation. There 

 exists only an infinity of solar systems, which taken toge- 

 ther 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 invi- 

 sible) is an assertion which betrays an ignorance of the 

 essence of light. A darker central body is an absurdity.

215. Sun arid planet, as individual spheres, have also 

 their own individual gravity. The aether therefore must 

 exist otherwise than in the universal sphere. The next 

 change of the aether 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 aether 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 aether ; 

 they are condensed aether. The heavenly bodies of a 

 solar system have derived their mass out of the aether, 

 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 cal- 

 culated how much rarer the aether is than e. g. water. 



217. The aether is therefore not absolutely impon- 

 derable, but only so in relation to the heavenly bodies. 

 Light and heat are therefore ponderose substances, though 

 they are not ponderable.
