This book investigates several dimensions of the concept of cosmopolitanism since Kant. The
first of these dimensions is a world vision that considers the construction of a »cosmopolitan
self« as a question of justice. The second is the idea that a local political-legal order is
fully democratic only if it respects the environment and the human rights of all people of the
world regardless of their citizenship. The third dimension concerns the practice of
crossborder associations between individuals institutionalized or not (cosmopolitics as
Balibar called it). The fourth considers individuals as subjects of international law as in
the case of individual petitions concerning human rights through the European Court of Human
Rights and individual responsibility in international criminal law. Finally the fifth
dimension is a form of ecological consciousness based on the relationship between the self and
the cosmos which would imply a profound revision of modern anthropocentric concepts.
