In this text is carried out a study of the Derrida’s concept «cap» in comparison with the way in which Heidegger sets out the «polis» in his texts developed throughout 1935 and 1943. In this way, through the word «khôra», shared this by Heidegger and Derrida, the topology of human dwelling is tackled as dimension necessarily opened towards the other. Thus, it is realized, through the «hospitality» showed by Heidegger and Derrida, the difference between the two regarding the possibility or (...) impossibility of this aporetic place for human dwelling.
