Why Can the Image of the City be Formed?
  The aim of this short paper is to summarize my recent preprint (arXiv:1209.1112), in which I proposed a novel and probably controversial view about cognitive mapping; that is, the image of the city out of the underlying scaling of city artifacts or locations. The scaling refers to a recurring structure of far more small things than large ones. In this paper, I attempt to further clarify the central argument, and identify some possible areas of misunderstanding for readers.
