Derrida said: “there is nothing outside the text”. In human landscapes, there is nothing outside the boundaries.
Human Territories are areas delineated by boundaries with the aim of limiting the rational space: exterior/interior, inside/outside. These limits could be man-made or nature-made. One example of artificial boundary is a section of the Mexico-USA border (see image below) where a fence on the Sonoran Desert separates two national territories. On the same landscape there is an inside and there is an outside. Natural boundaries also confines settlements, this is the case of the Pacific Ocean when it marks the limit of the Mexican seaport of Mazatlan (see image above). In order to clarify this point I propose a third example with a picture of the Rio Hondo (see last image). This river establishes the division of two national states; on the right side México, on the left side Belize. Natural or man made, a given geography is not only a passive surface but also a symbolic landscape. It could be said that a symbolic landscape is the rationalization of a territory.
