It is not that the historian can avoid emphasis of some facts and
not of others. This is as natural to him as to the mapmaker, who, in
order to produce a usable drawing for practical purposes, must first
flatten and distort the shape of the earth, then choose out of the bewilder-
ing mass of geographic information those things needed for the purpose
of this or that particular map.
My argument cannot be against selection, simplification, emphasis,
which are inevitable for both cartographers and historians. But the
mapmaker’s distortion is a technical necessity for a common purpose
shared by all people who need maps. The historian’s distortion is more
than technical, it is ideological; it is released into a world of contending
interests, where any chosen emphasis supports (whether the historian
means to or not) some kind of interest, whether economic or political
or racial or national or sexual.
Furthermore, this ideological interest is not openly expressed in
the way a mapmaker’s technical interest is obvious (“This is a Mercator
projection for long-range navigation-for short-range, you’d better use
a different projection”). No, it is presented as if all readers of history
had a common interest which historians serve to the best of their ability.
This is not intentional deception; the historian has been trained in a
society in which education and knowledge are put forward as technical
problems of excellence and not as tools for contending social, classes,
races, nations.
Howard Zinn (via zouave)
There’s been a lot of work by geographers about how selection in cartography also reflect ideological biases and are not merely technical. Zinn actually oversimplifies the role of the cartographer in society (which is pretty ironic, considering what he’s talking about)- mapping human society has been and always will be a political act. Maps can objective in one important sense, however: the information they convey is accessible to anyone who can read and interpret them. However, the choices of what get put on maps that represent people and human activity are never objective in the sense of being politically neutral, as they will always, by their very nature, show some things and hide others. Many historians of geography have explored the hidden and overt biases that shape the process of map-making. So the considerations Zinn so rightly points out here are just as important for cartographers as historians.
