plus a subject, or self, is the only universe which can be known (Props. I. and II.) The only universe which can be thought of is the universe which can be known (Prop. XI.) Therefore, objects plus a subject, or self, is the only universe which can be thought of. Consequently, whenever any mind or ego thinks of the universe as independent of itself, it must still think of it as made up of objects plus a subject. Therefore, the only independent universe which any mind or ego can think of is the universe in synthesis with some other mind or ego.
