Undoubtedly, there are only discomforts in culture, in inculture, in identity; embarrassments of identity, enigma of national identity, murderous identities, etc., because there is first of all some intercultural discomfort. This is what seems not to have always been sufficiently explained. But what is there between cultures, what happens there? To ask the question in this way, is it not to say the "between" from some place? Perhaps it is necessary to persist in calling this "in-between" border, which makes one neither completely outside nor completely inside, and which makes one both inside and outside. A kind of non-place that is no less inhabited. But who "we"? And inhabited by whom? A philosophy instructed by the field will attempt to visit these non-places inhabited by people-borders, and to elaborate the metaphorological and cosmo-political consequences of a fact: their number will increase as climate change proceeds.
