The three lectures collected in this volume were prepared without any intention of publication. They were delivered for the purpose of drawing attention to the links which connect the proposal for a League of Nations with the past, to the difficulties which stand in the way of the realisation of the proposal, and to some schemes by which these difficulties might be overcome. When it was suggested that the lectures should be brought before the public at large by being issued in book form I hesitated, because I was doubtful whether the academic method natural to a University lecture would be suitable to a wider public. After consideration, however, I came to the conclusion that their publication might be useful, because the lectures attempt to show how the development initiated by the two Hague Peace Conferences could be continued by turning the movement for a League of Nations into the road of progress that these Conferences opened.
Professional International lawyers do not share the belief that the outbreak of the World War and its, in many ways, lawless and atrocious conduct have proved the futility of the work of the Hague Conferences. Throughout these anxious years we have upheld the opinion that the progress initiated at the Hague has by no means been swept away by the attitude of lawlessness deliberately—'because necessity knows no law'—taken up by Germany, provided only that she should be utterly defeated, and should be compelled to atone and make ample reparation for the many cruel wrongs which cry to Heaven. While I am writing these lines, there is happily no longer any doubt that this condition will be fulfilled. We therefore believe that, after the map of Europe has been redrawn by the coming Peace Congress, the third Conference ought to assemble at the Hague for the purpose of establishing the demanded League of Nations and supplying it with the rudiments of an organisation.
