This is, I think, the only complete translation into English of Kant's essay, including all the notes as well as the text, and the translator has added a full historical Introduction, along with numerous notes of her own, so as "to meet the needs of the student of Political Science who wishes to understand the relation of Kant's theories to those of Grotius, Hobbes, Locke, Rousseau etc., and of the general reader who wishes to understand the significance of Kant's proposals in connection with the ideals of Peace Congresses, and with the development of International Law from the end of the Middle Ages to the Hague Conference."
