Cosmopolitanism and Kant (Yay!)
Cosmopolitanism is the philosophical ideology that all human beings belong to a single community based on shared morality. Someone who adheres to the idea of cosmopolitanism may be called a cosmopolitan or cosmopolite. In his 1795 essay Perpetual Peace: A Philosophical Sketch, Immanuel Kant states that ius cosmopoliticum (cosmopolitan law/right) is a guiding principle to protect people from war, and enforced this right by the principle of universal hospitality. Kant writes that the "use of the right to the earth's surface which belongs to the human race in common...would finally bring the human race ever closer to a cosmopolitan constitution."
