Cognoscenti Dave “Skunkmeat” Lofranco brings this to our attention of an example of the difference between the Objective Reality we all share and the Perceptual Reality in which each of us lives in a private world, alone. Communication happens in that limited space where your Perceptual Reality overlaps with mine.  Conversely, there are things in your perceptual universe that don’t exist in mine. And vice-versa. The Cognoscenti will remember this as Concept 234 in The Magical Worlds Communications Workshop.
