A stick figure is speaking (though we cannot read what the actual words are) while walking across a chart of labelled, concentric circles. The figure began at "area of expertise" then moved through "realm of general understanding", "province of vague knowledge", "field of nebulous awareness" and "domain of dubious speculation". The figure is now about to step from "region of pure imagination" into "zone of utter ignorance".ALT
