Abstract

All people edit. We don't call it editing, of course. We call it thinking. Frogs think too. When a frog thinks'food', it looks for a moving dot; in a cage of dead flies, a frog starves to death. When something doesnot fit the category, it is not seen. Humans likewise. "Do you see nothing there?" Hamlet asks; "Nothingat all; yet all that is I see", Gertrude replies, exemplifying our difficulty with seeingthings not valued.[1] The reason for such editing is mental economy; given physiological computationallimits, operating with a limited set of categories and properties avoids cognitive paralysis
