CONCEPT
Symbol System
A structured means of reference—organized according to syntactic and semantic rules—through which versions of reality are constructed rather than copied.
In
Goodman's philosophy, a symbol system is not a transparent window onto a pre-existing reality but a constructive apparatus through which different versions of reality are made. A painting, a scientific equation, a musical score, and a literary text are all symbol systems—each organizing experience through structured
symbolic reference according to the conventions of its medium. The symbols (colors, mathematical notation, notes, words) refer to their subjects not by copying them but through modes of reference Goodman identified with technical precision:
denotation (direct reference),
exemplification (possessing and highlighting properties), and
expression (metaphorical exemplification). What distinguishes symbol systems from mere marks is their systematic character—the organized relationships among symbols and
between symbols and their referents that allow the system to function cognitively, yielding understanding rather than merely triggering responses. The cognitive value of a symbol system depends not on its fidelity to a source but on its
rightness of rendering—its coherence, fit with other accepted versions, and productivity of insight.
