Most other political cosmopolitans did not go as far as Cloots. Immanuel Kant, most famously, advocated a much weaker form of international legal order, namely, that of a ‘league of nations.’ In Toward Perpetual Peace (1795) Kant argues that true and world-wide peace is possible only when states organize themselves internally according to ‘republican’ principles, when they organize themselves externally in a voluntary league for the sake of keeping peace, and when they respect the human rights not only of their citizens but also of foreigners. He argues that the league of states should not have coercive military powers because that would violate the internal sovereignty of states.
