Space of Difference: The Dichotomy of Heterotopia and Heterotopy on Foucault and Lefebvre

In the city, it is increasingly encountered the spaces that are pushed out of the free use of the citizens. This push out procedure – the force to abandon the free use of urban space- also indicates that everyday life occupied by spaces or spatial facilities controlled by state apparatuses. This situation can considered as an attempt of power to create homogeneous, boring and sterile spaces in the city. Power tends to create a sequence of spaces (not system) or an urban environment (not pattern) where not only the physical control is possible by the digital control mechanisms, but also isolated from diversity, and the decreased depth of social interactions. In the place where the follow-up mechanisms cannot operate, power tends to inhibit physical accessibility. It is obvious that "heterotopic" spaces are in an extinguishing process by power. In this context, could the concepts of "Heterotopia" of Foucault and "Heterotopy" of Lefebvre taken into the consideration to be able to revaluate/reread liberated and public spaces of the city? Although these two concepts seem to describe the “space of difference”, it is designated there are clear distinctions between them. This article is an attempt to unfold the differentiation of the “space of difference” within a holistic approach. This text is written to re-read the spaces of difference and to recount the disappearing liberated side of urban life
