It has always struck me that iconic figures in non-scientific academic fields spend a great deal of time discussing whether their particular fields are art or science.
Broadly speaking, science is the implementation of methodological
activity and, as John Lewis Gaddis points out in The Landscape of History , even within disciplines irrefutably
classified as scientific--geology, paleontology, chemistry, physics,
astronomy, for example--the criteria or definitions of methodological approaches
vary.
I'm going to offer an equally broad definition of historical
study, paraphrasing Eric Hobsbawn: the process of bringing coherence to
the past. Coherence requires structure, logic, order, consistency, achievable through a variety of approaches, perspectives, and processes. Like science, historical research is a
little inductive, a little deductive, a little empirical, but methodological nonetheless. The inter-disciplinary Venn diagram includes huge areas of overlap.
History, however, is essentially democratic; science, less so. Every man a
historian. Not so, every man a physicist. The internet has increased accessibility and the sense of public ownership of
history and its tools, the raw materials of the historic record, and, it seems to me, commensurately
increased the responsibility of professional practitioners to define
and expose how they do what they do. In part, this is professional protectionism. In part, it ensures that coherent narratives define fractals of the past and inform the present. Gaddis is right, I think. Transparency lifts the burden of a constructed past if we know how and why a narration represents history as it does.
But what does this book have to do with cartography? It's all in the metaphors (and even Gaddis couldn't restrain from throwing in one sports metaphor--rules of the game intersecting with Machiavelli, no less). Cartography is science and art, and as Gaddis makes clear, both the science and the art of map production are representational, and historical maps are necessarily objects that must be interpreted.
It gets tricky. On the one hand, we can interpret many maps as the tools of power and empire; some as models of the control of man over nature; others as communication devices. They are created by individuals, groups, printing presses, computers. A list is endless, but I'm limiting it here to geographical reconstructions, not concept, imaginary, or abstract mapping. The trick with these maps,too, is that they are usually intended to replicate physical reality on a usable scale. The more accurate a map, the better. But is a satellite view of the earth subject to the same interpretive categories as the first maps of new continents? Do comparisons exist between the decontextualized cartography of the DC or London subway systems and detailed urban reconstructions? The categories of analysis also seem endless and tied to variables.
The Landscape of History applies to cartography on one level, simply because Gaddis advises historians (and perhaps scientists) to apply a contextualized, methodological approach to framing and answering the questions that evidence presents through flexible views of time, space and structure, and the willingness to perform a few mental gymnastics.
