Despite the centrality of the topic of peace to international studies and the proliferation of volumes by such groundbreaking thinkers as Rousseau, Bentham, and Kant, there is no single text available that caters to this aspect of eighteenth-century political theory. Addressing this gap by providing a contemporary compilation of the eighteenth-century “perpetual peace” proposals together with a cogent introduction to the topic’s contemporary links to global governance and cosmopolitan democracy, this volume features full-text proposals by Rousseau, Bentham, and Kant, as well as selected extracts from the lesser-known Saint Pierre, accompanied by individual introductions and reader-accessible commentary.
