But, for me, the meanings can also be well separated when describing particular sinsigns. In the mathematically relevant case, the concept of a diagram, deeper insight can be gained by recognizing that diagrams are not only written / drawn, they are purposeful expressions of the author’s beliefs and intent. Often, this implies a purpose for drawing the diagram as a design or plan for an object to be constructed. This construction can include a vast array of facts that are synthesized together to create a whole from its parts. Such constructions of diagrams (“blueprints”) can stretch across multiple disciplines, as you are well aware. It may be future oriented. Thus, the intent of an diagram can be remote from the simpler concept of an index, a mere listing. A listing presupposes some categorical rule for ordering the contents of the list. An index can be used in propositions to indicate “truth”. Often, an index is an indicator of the past. In modern discourse, we often speak of symbol systems for particular sinsigns, such as the experience of electricity (in all it’s manifestations - physical as well a psychic.) Such symbol systems require an internal coherency in order to give consistent meaning within the community of knowledgable users of the symbol system. One reason for communicating these highly abstract notions it that CSP appears to have been cursed by not acknowledging the special assets enclosed within the symbols of chemical table of elements. In the chemical sciences, the chemical symbols can serve as index of the past, a diagram for design of future objects or both! Cheers Jerry .
