"Evidently, the proper semantic theory for a highway map, or any other geographic map, is robustly holistic. Semantic significance accrues to such map elements not one by one, and independently of the semantic significance of the of neighboring map elements. Rather, they gain their semantic and referential significance collectively, and the unique significance of each distinct element is an irreducible function of all of the within-map relations it bears to every other map element. For maps, at least, no other semantic theory is even worth talking about."
