159. Points, which strive towards the centre, are compressed, because they would all occupy one and the same spot. These points, however, are forces, which take up space and therefore exclude other points. A space that excludes another is Matter. Everything which has been said of gravity holds good in respect to matter; for matter is only another word for gravity. A heavy thing is a material thing.
160. To the totality of a thing belongs not merely its figure nor its tension or motion simply, but also its gravity. This is, however, a whole sphere. Matter is, consequently, a total position of the primary act, a trinity of ideas.
161. Matter has been imparted with space and time. All space is material; ay, matter is itself the space and the time, the form and the motion; for space is nothing special, but only extended or formed force. It is here also shown that the nothing does not exist. There is as little nothing in the universe as there is an 0 in mathematics. So soon as the nothing is, there is something. The whole universe is material, is nothing but matter; for there is the primary act eternally repeating itself in the centre. The universe is a rotating globe of matter.
162. But the universe is an acting gravity, a matter, in which the centroperipheric antagonism is active; it is therefore everywhere matter only, which acts. There is no activity without matter, but also no matter without activity, both being one; for gravity is itself the activity, and itself the matter. Matter is only limited activity. A matter which does not move is not; it can only subsist through continuous origination, through life. There is no dead matter; it is alive through its being, through the eternal that is in it. Matter has no existence in itself, but it is the Eternal only that exists in it. Everything is God, that is there, and without God there is absolutely nothing.
163. It is an illusion to believe that matter were an actual something subsisting in itself. It is even so with numbers, upon which a reality also is bestowed, when they are still demonstrable nothings. A number is nothing truly than an affirmation several times repeated, a reiterated deposition of what is nothing, what is no number. This deposition happens likewise in the universe, where it is the primary act, that is deposited. Where, however, this is, no other station can occur. This exclusive property is usually called the Impenetrable, the Material. It cannot be said in what spot matter arises, so secretly and suddenly does it start into existence. It is matter properly at the first manifestation of being, of time and of space; for at the same instant also the line, surface, density and gravity have been given. The line does not exist if it does not act; the sphere does not exist if it be not inert, i. e. if its forces do not strive towards the centre, and consequently to connexion. Nothing exists if it is not material. Matter is accordingly coexistent with the presence of God.
164. The Immaterial does not exist; for even the Material which is not, is the Immaterial. Everything that is, is material. Now, however, there is nothing that is not; consequently, there is everywhere nothing immaterial. Immateriality is only a postulate principle, by which to get at matter, like the 0 in mathematics, which is nothing in itself, does not even exist, but that still must be posited, in order that numbers may bear a reference to it.
165. God only is immaterial; he is the only permanent immaterial invention, and the axiom being the Formless, Polarless, Timeless. A spirit with form is a contradiction. But the matter also does not exist, because matter is nothing, because it is only a sphere of central actions, which is gravity.
166. The material universe is called nature. There can be only one nature, as well according to time as to space and to divine animation. There is only one God, whose operations expressed, or materially posited, are nature. Nature has originated out of nothing like time and space; or with these has nature also been. God has made heaven and earth out of nothing.
167. God has not found matter co-eternal with himself, and, like an architect, arranged this to his fancy; but he has, out of his own eternal omnipotence, by his will simply, evoked the world out of nothing unto existence. He has thought and spoken, and it was.
168. The doctrine of matter is the Philosophy of Nature. It is therefore the science also of all Singulars, like geometry and arithmetic; thus at bottom is only the third part of mathematics, and is even as certain and demonstrable as this.
