Being

What truly is, is what is unchanging: the Forms, not the shifting world of sense.

Being is said in many ways, and the primary way is substance: the individual thing that exists in its own right.

Beyond Being is the One: ineffable source from which all reality flows.

God alone truly is ('I AM WHO AM'), and all other beings exist by participating in his being.

God is the sheer act of being, *ipsum esse subsistens*, and every creature is a composition of essence and existence.

I think, therefore I am: the first certainty is the being of the thinking self.

There is only one substance (God or Nature), and everything else is a mode of it.

Reality is composed of simple substances, monads, each mirroring the whole universe from its own point of view.

Being is not a real predicate, and the thing-in-itself lies forever beyond our knowledge.

Pure being and pure nothing are the same; becoming is their truth, and the whole is the result.
