The very idea of ​​democracy is always unfinished, always to be conquered. There is in the idea of ​​globalization, and among those who claim it, an idea of ​​the completion of the world and the end of time which denotes a lack of imagination and a swallow in the present which are deeply contrary to the scientific spirit and political morality. We must today rethink the frontier, this reality constantly denied and constantly reaffirmed. We must rethink the notion of boundaries to try to understand the contradictions that affect contemporary history. A border is not a dam, it's a passage. Borders never fade, they redraw. The border always has a temporal dimension: it is the form of the future and, perhaps, of hope. This should not be forgotten by the ideologues of the contemporary world, who are suffering from too much optimism or pessimism, too much arrogance in every case.
