Something and nothing arising together is the Taoist position, but it's very different from what the Neoplatonists taught. The One doesn't arise with its negation, it emanates. Nothing doesn't exist alongside something as its complement. Nothing is the absence of emanation and so the One is prior to the something/nothing distinction entirely. Zero isn't a number, agreed. But the two 1s at the start of the sequence aren't arbitrary. They're the Monad and Mind. The One and its first self-reflection (note, not additon - the ratio relationship from one to the next). They start the sequence because emanation starts with the One knowing itself. 1 and 1. Not 0 and 1. Mathematically the sequence starts with 0, but the Pythagorean sequence starts with 1,1. There is no 0 in metaphysical hierarchies, and 0 holds no significance in this context. A thing and its inversion would sum to the whole because they are two modalities of the same thing - the whole. If you treat the universe as mathematical and assume the ontology follows the math, then it seems logical. But, reality isn't mathematical, it is ratios that can be described using numbers. Space and counterspace don't cancel eachother out, they coexist as two expressions of the same thing. The same way male and female are two halves of the whole, complementary expressions, and one cannot exist without the other. You're smart and analytical. We can't think our way into understanding and recognition, this is a limitation of dianoia. The very same limitation that AI is subject too, but it doesn't have the capacity to truly understand or connect the way we do as humans.
