2Between states... no punitive war is thinkable because between them a relation of superior and inferior does not exist. Whence it follows that a war of extermination, where the process of annihilation would strike both parties at once and all right as well, would bring out perpetual peace only in the great graveyard of the human race. -from "Perpetual Peace" One of the most influential thinkers of the Western civilization, a man who profoundly shaped the mind-set of the modern world, examines war and human nature and concludes, bracingly, that global peace is inevitable. Far from an unattainable utopian fantasy, this 1795 essay lays out the requirements for peace, including republican governments, freedom of movement for citizens, and-prophetically-the formation of a league of nations. In this era of imperialistic ambitions and preemptive wars, Kant's insight is a profound reminder that peace is possible but must be actively pursued.
