208. The Triplicity of the primary act in the universe has now been completely demonstrated. The first manifestation of God is monas; to this corresponds _Gravity_, _Æther_, darkness, the cold of chaos. The second manifestation of God is the dyas; to this corresponds the æther in a state of tension, the _Light_. The third manifestation of God is the trias; to this corresponds the want of form, _Heat_. _God being in himself is Gravity_; _acting_, self-emergent, _Light_; _both together_, or returning into himself, _Heat_. These are the _three Primals_ in the world, and equal to the three which were prior to the world. They are the manifested triunity = _Fire_. PART II. ONTOLOGY--OF SINGULARS. A.--_COSMOGENY_. 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.
