===6.21. Building Bridges Between Representations===

On the way to integrating dynamic and symbolic approaches to systems there is one important watershed that has to be crossed and recrossed, time and time again.  This is a form of continental divide that decides between two alternative and exclusive ''modes of description'' (MODs) or ''categories of representation'' (CORs), and marks a writer's moment to moment selection of ''extensional representation'' (ER), on the one side, or ''intensional representation'' (IR), on the other.  To apply the theme, in this section I address the task of building conceptual bridges between two different ways of describing or representing sign relations:  (1) the ER that describes a sign relation in terms of its instances, and (2) the IR that describes a sign relation in terms of its properties.

It is best to begin the work of bridge building on informal grounds, using concrete examples of ERs and IRs and taking advantage of basic ideas about their relationship that are readily available to every reader.  After the overall scheme of construction is roughed out in this fashion, I plan to revisit the concept of representation in a more formal style, examining the balance of its in  and ex  "tensions" with a sharper eye to the relevant details and a greater chance of compassing the depths of form that arise between the two points of view.
