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. German metaphysician IMMANUEL KANT (1724-1804) served as a librarian of the Royal Library, a prestigious government position, and as a professor at Königsberg University. His other works include Observations on the Feeling of the Beautiful and Sublime (1764), Critique of Pure Reason (1781), and Groundwork of the Metaphysics of Morals (1785).
