"Any man must, inasmuch as he can, cultivate and maintain toward others a peaceable sociality that is consistent with the native character and end of humankind in general." -Samuel von Pufendorf, The Two Books on the Duty of Man and Citizen According to the Natural Law (1927) De Officio Hominis Et Civis Juxta Legem Naturalem Libri Duo, Volume I (1927), originally published in 1673, is a replica of the 1927 edition with the original Latin text. Also available from Cosimo Classics are Volume II, which contains the English translation by Frank Gardner Moore, and a comprehensive two-volume edition in Latin and English. This book combines the theories of Grotius and Hobbes into the author's own idea that the natural state of man is at peace not war. This and other foundational concepts of international law are presented in this classic for legal scholars and those intrigued by the history of law.
