The spatial dimension of democracy Since the time of the Greeks, democracy has been understood to have a spatial dimension and so, by extension, an element of scale. Plato measured the polis, the unit of democratic citizenship, at five hundred citizens, an extremely tractable size for a community that seeks to express itself through direct engagement.

What kind of world it's going to be The wonderful thing about living in a world of our own creation is that we get to choose what kind of world it's going to be—at least in principle. But the promise is meaningful only if a broad enough "we" can be engaged in the process. At present, mechanisms and democratic institutions for making collective decisions about the deployment of technology are hopelessly cumbersome. How can anyone make a sensible choice without being able to weigh one alternative against another? Brian Hayes, Infrastructure: A Guide to the Industrial Landscape democracypoliticsclimatechoice
Paths, edges, districts, nodes, landmarks The contents of the city's images which are referable to physical forms can conveniently be classified into five types of elements: paths, edges, districts, nodes, and landmarks. Paths are the channels along which the observer customarily, occasionally, or potentially moved. Edges are the linear elements not used or considered as paths by the observer. They are the boundaries. Districts are the medium-to-large sections of the city, conceived of as having two-dimensional extent. Nodes are points, the strategic spots in a city into which an observer can enter, and which are the intensive foci to and from which they are traveling. Landmarks are another type of point-reference, but in this case the observer does not enter within them, they are external. They are usually a rather simply defined physical object: building, sign, store, or mountain. Kevin Lynch, The Image of the City City districtsAs a kind of gateway cities
