Representatives of the former, included Jean-Jacques Rousseau, in Extrait du Projet de Paix Perpetuelle de Monsieur l'Abbe Saint-Pierre (1756),[3] Immanuel Kant, in his Thoughts on Perpetual Peace.[4] and Jeremy Bentham who proposed the formation of a peace association in 1789. Representative of the latter, was William Wilberforce who thought that strict limits should be imposed on British involvement in the French Revolutionary War based on Christian ideals of peace and brotherhood.
