And then in turn, the only way to have the existence of both (some)thing and its context is for the pair to form a mutual or complementary dichotomy.If you accept that something exists and can also accept the absence of that something, then you have a context for saying nothing exists.
Each has to become the other's context, so that each can exist.
So the idea of nothing - an absence of things - demands a context of thingness to be an acceptable possibility. And when you look at it from the other angle, you have to say that an absence of nothing is equally much a part of this deal. So in turn, this yields the counter-idea of everythingness, or infinity.
There is the absence of thingness, and the absence of absence. Together, they are the boundary limits on what is in fact possible. Reality lies within the two extremes.
