If we ponder the things which are not real or which we say are not real. They fall into a set number of spaces.
A Metaphysical Space
An After Life
A Before Life
It would seem peculiar to say that things which don’t exist differ from one another, but we can’t rightly call them the same either.
But they differ in the spaces they occupy in perception, so that even if we tried it’s not entirely clear we could invent new ones.
So that if we tried to identify some new form of not reality, there would literally be no space to put it in perception.
So that of the things which we say are not real, there are still only a limited set of possibilities by which we can delineate them so that they fall into only a set number of perceptual spaces, for us to conceive upon.
We can call these spaces pseudo because we cannot say where are how they would exist.
