Abstract
This essay is a survey upon Kant’s Sweet Dream of Perpetual Peace. According to Kant, a permanent peace could be achieved under the condition of the creation of a Federation of States. This Federation of States will be rest upon three fundamental requirements—i.e., democracy, reason, universal hospitality. Kant’s idea of global Federation of States should not be confused with existing nowadays Unions of States, such as European Union, which depend heavily upon a central authority and a complicated bureaucracy.
