An object called an "apple" left in a jar for months becomes a putrid liquid because of its underlying, dynamic, sub-microscopic structure , but the label "apple" does not change. The word "steak", at a lower verbal order, may imply "something to eat" at a higher verbal order, but in the sub-microscopic domain, a particular steak may be contaminated with poisons created by harmful bacteria that we could see only on microscopic levels. Thus the differential sets up a hierarchy of order, with the submicroscopic domain of dynamic change coming first, the relatively stable universe conveyed non-verbally by our senses coming next, and then the verbal levels.
