Philosophical Investigations Note 8

Things are the intersection of systems, defined in terms of the ways they relate to each other.

So is meaning, a second-order relation of things (embodying the relation of systems of thought).

Descartes 1

Descartes was misguided. The world is simulation. Then why something not nothing? Existence is relative. So must the self exist? Only in relation to that which it exists in relation to. The self and the world only exist in relation to each other.
