You can not see what I see because you see what you see. You can not know what I know because you know what you know. What I see and what I know can not be added to what you see and what you know because they are not of the same kind. Neither can it replace what you see and what you know, because that would be to replace yourself. Anything you see or hear or experience in any way at all is specific to you. You create a universe by perceiving it, so everything in the universe you perceive is specific to you.

-Douglas Adams
