We intend articulate the subject's dimension with the place, task accomplished in two poles: an analyze of relation subject/place in the everyday practice through of the body and, beyond, we'll explore the formative relations of being in its broader dimension (because make a reference for what it is) about the complicity of being between subject and place. To approach these questions, we have been bring to Geography a ontological perspective, starting to the Phenomenology of own body insofar as the subject is open to the world, as being-in-world. And, as being-in-world, is all the time immersed in their everyday occupations. In a similar way, to understand the mutual institution subject/place at identity level, the argumentation too pass through the Phenomenology: we look what is the sense of inhabit this or that place for the man which there make their experience of life - what is the implication, for the being-subject, precisely, inhabit this or that place? The answer we intend to construct: a mutual constitution, formative, of the being and of the place in its trajectivitys ( a la Berque [2012]) always operating.
