In modern times, the passport has become a symbol of national sovereignty and control by each nation-state. That control works both for citizens within a nation and all others outside. All nations thus collude in the system of control of travel rather than its freedom. If freedom of travel is one of the essential marks of the liberated human being, as stated in the Universal Declaration of Human Rights, then the very acceptance of a national passport is the mark of the slave, serf or subject. The World Passport is therefore a meaningful symbol and sometimes powerful tool for the implementation of the fundamental human right of freedom of travel. By its very existence it challenges the exclusive assumption of sovereignty of the nation-state system. It is designed however to conform to nation-state requirements for travel documents. It does not, however, indicate the nationality of its bearer, only his/her birthplace. It is therefore a neutral, apolitical document of identity and potential travel document.
