A new view of the role of art and science in cartography is clearly needed. It is probably a mistake to view maps as objects that contain varied amounts of scientific or artistic content for which we must determine an appropriate balance (as both Keates, 1984, and Robinson, 1952, seem to, with Keates arguing for more art and Robinson for more science). Instead, it makes more sense to consider complementary artistic and scientific approaches to studying and improving maps, both of which can be applied to any given cartographic problem. The artistic approach is intuitive and holistic, achieving improvements through experience supplemented by critical examination (where critical examination implies expert appraisal of the results of our cartographic decision-making efforts). It draws on science in using perspective, understanding of human vision, color theory, and so on.

Two developments of the past four decades played crucial roles in establishing a research agenda for the study of map symbolization and design. The first was Arthur H. Robinson's dissertation (published as The Look of Maps in 1952), with its call for objective research, and the second was the adoption in the 1970s of a paradigm of cartography as communication science.

Without categorization, maps would not be possible.
