These three ideas of the Eternal are all equivalent to each other, are the same primary act, each of them being whole and undivided, but each otherwise posited. The positing primary act is the whole Eternal; the posited is likewise the whole Eternal, and that which is subtractive, retrogressive, combining the two first, is also the whole Eternal. Although all three ideas are equivalent to each other, still the positing idea ranks first, the posited second, and the combining third; not as if they had first arisen successively (this is impossible, for they are coexistent, namely, before all time), nor as if they occupied different positions (for they are everywhere); but only according to their order and value. How one may be three and three one, is thus rendered comprehensible only by mathematics. 68. The first idea is the original, that therefore which is thoroughly independent, which having arisen from and being based upon itself, has consequently emerged from nothing else; in short, it is the eternal idea, like the mathematical 0 = _Monas aoristos_. Everything is possible with it; it can propose and solve all problems, knows therefore everything and creates everything. It is the generative, creative and paternal idea. 69. The two other ideas have emerged out of the first, although apparently equivalent to it; yea, they have themselves issued out of themselves. The second idea is, therefore, _Dyas aoristos_, and corresponds to the mathematical +; the third idea is the _Trias aoristos_, and corresponds to the mathematical-, so that by the three the primary trinity 0 +-is completed. The first idea labours or, what is more, rejoices from all eternity to convert itself into the two others. The action or the life of God consists in eternally manifesting itself, eternally contemplating itself in unity and duality, eternally dividing itself and still remaining one. The second idea has issued next from the first, and is therefore related to it as Son is to Father, when the ideas are viewed as personified. The third idea has emerged conjointly from the second and first, and forms therefore the spiritual union, the mutual love between both. It may be therefore simply called Ghost or Spirit, if it is thought of as personified.
