Jon et al., The basic point of my post was that the interpreter of a sign can keep its dynamic object “in view” only by means of the indexical function of the sign, which connects it to actual experience. Diagrammatic signs are not so good at that.
The relevance to John's original post, as i see it, is this: if theorematic reasoning is only a mathematical procedure, it leaves out the experiential element of Peirce's methodology and his pragmatism. Mathematics is not a positive science, meaning that it involves no actual experience (other than the experience of doing mathematics, in which the universe of discourse is entirely imaginary). All positive sciences (including phaneroscopy, logic and semiotic) deal with what Peirce calls real relations as opposed to relations of reason (CP 1.365, for instance). A proposition in a positive science thus must employ a genuine Index <http://gnusystems.ca/TS/snm.htm#gndx> , as opposed to a degenerate index such as ‘the letters attached to a geometrical or other diagram’ (EP2:172).

Dear Gary, All ... I was obviously having a lot more fun with words in those days ... sigh, good times ... the point of it all being I always see the whole complex of meanings associated with the Greek root "pragma, pragmata" through the more threadbare veil of the Latin "object". That complex contains all the senses of aims, concerns, ends, goals, intentional objects, and purposes we tend to express more obliquely through the use of "object" to mean "objective". Still, the latter use does have some currency in cybernetics, operations research, and systems theory, so it's a handy sense to keep in mind.
