Written in 1795, this thought-provoking essay presents Immanuel Kants vision for enduring peace among nations and peoples. Kant outlines essential means to achieve this peace, advocating for a federation of nations that preserves their sovereignty. Notably referred to as a league of nations in one translation, the essay is enriched by compelling supplements and appendices. The supplements delve into natures use of war and its ultimate push towards peace. Meanwhile, the appendices explore whether Kants theory can be practically applied, distinguishing between the moral politician and the political moralist, and revealing how practical concerns can mask behaviors that foster discord and conflict. This essay remains strikingly relevant today, serving as a poignant reminder of our obligation to seek perpetual peace. Kant warns that without such efforts, we may only find perpetual peace in the grave, buried alongside the violence of humanitys past. - Summary by D.E. Wittkower
