The three worlds: the causal world, the intellectual world and the numerical world. The reality of the “material” world (taking this adjective in the broadest sense) depends on number. As a result, in this world we are, each being, mere numbers. But numbers have a logic, a reason. They don’t presuppose anything else. (They don’t even presuppose their being thought). But numbers have an order. Because of this, above the numbers is the reason for the numbers. This reason is intrinsic to all numbers. We only understand it through this phenomenon taking place between the numbers, which is called the Law. But this reason must have an origin, a cause. Therefore above the rational world is the causal world. The numerical world is ruled by the gods. That is, in relation to the world we’re used to, polytheism is the Truth. In the rational world there are no longer any gods, or rather, that world is above the gods. That world is not real; that is to say, there is nothing in us that can affirm its existence. Nor can it be said that it exists, because being and reality are categories of Number. Therefore, this rational world cannot be reached either by the senses that teach the idea of Reality, or by reason, which teaches the idea of Law, or by Consciousness, which teaches the idea of Being. No faculty of ours, no mode of perception imaginable, can take us to the rational world: all we can do is see its reflection amongst numbers. Because there are (1) numbers, (2) relationships between numbers (the reflection of Reason), (3) (abstract) existence of numbers and relationships between them, because what is common between numbers and their relationships is to be “things” that exist.
