In our minds, we have memories of our world, and together they constitute a mapping: a table of tokens equivilated to objects, experiences and topographies in real life.
We live in this mapping, more than we live in the world, as we only know the world from memory except in the tiniest portion that we're looking at right now (for you: the page onscreen, one direction's glance of the room the computer is in, what's on your desk, and portions of your body except your face, unless you have a mirror present, at which point you're looking at yourself backward).
Is this real?
We know the world through metaphor, only.
