| − | Tables 14 and 15 summarize therelations that serve to connect theformal language of sentences with the logical language of propositions.  Between these two realms of expression there is a family of graphical data structures that arise in parsing the sentences and that serve tofacilitate the performance of computations on the indicator functions.  The graphical language supplies an intermediate form of representation between the formal sentences and theindicator functions, and the form of mediation that it provides is very useful in rendering the possible connections between the other two languages conceivable in fact, not to mention in carrying out the necessary translations on a practical basis.  These Tables include this intermediate domain in their Central Columns.  Between their First and Middle Columns they illustrate the mechanics of parsingthe abstract sentences of the cactus language intothe graphical data structuresof thecorresponding species.  Between their Middle and Final Columns they summarize the semantics of interpretingthe graphical forms of representation for the purposes of reasoning with propositions.

| − | Aside from their common topic, the two Tables present slightly different ways of conceptualizing theoperations that go toestablish their maps.  Table 14 records the functional associationsthat connect each domain with the next, taking thetriplings of a sentence <math>s_j,</math> a cactus <math>C_j,</math> and a proposition <math>q_j</math> as basic data, and fixing the rest by recursion onthese.  Table 15 recordsthese associations in the form of equations, treating sentences and graphs as alternativekinds of signs, and generalizing the denotation bracketoperator to indicate the propositionthat eitherdenotes.  It should be clear at this point that either scheme of translation puts the sentences,the graphs, andthe propositionsthat it associates with each other roughly in the roles ofthe signs,the interpretants, andthe objects, respectively,whose triples define an appropriate sign relation.  Indeed, the"roughly" can bemade "exactly" as soon as the domains of a suitable sign relation are specified precisely. | + | Aside from their common topic, the two Tables present slightly different ways of drawing the maps which go to make up the full semantic transformation. |
