Dr. Lord's volume on "American Statesmen" was written some years after the issue of his volume on "Warriors and Statesmen," which was Volume IV of his original series of five volumes. The wide popular acceptance of the five volumes encouraged him to extend the series by including, and rewriting for the purpose, others of his great range of lectures. The volume called "Warriors and Statesmen" (now otherwise distributed) included a number of lectures which in this new edition have been arranged in more natural grouping. Among them were the lectures on Hamilton and Webster. It has been deemed wise to bring these into closer relation with their contemporaries, and thus Hamilton is now placed in this volume, among the other "American Founders," and Webster in the volume on "American Leaders."
Of the "Founders" there is one of whom Dr. Lord did not treat, yet whose services--especially in the popular confirmation of the Constitution by the various States, and notably in its fundamental interpretation by the United States Supreme Court--rank as vitally important. John Marshall, as Chief Justice of that Court, raised it to a lofty height in the judicial world, and by his various decisions established the Constitution in its unique position as applicable to all manner of political and commercial questions--the world's marvel of combined firmness and elasticity. To quote Winthrop, as cited by Dr. Lord, it is "like one of those rocking-stones reared by the Druids, which the finger of a child may vibrate to its centre, yet which the might of an army cannot move from its place."
So important was Marshall's work, and so potent is the influence of the United States Supreme Court, that no apology is needed for introducing into this volume on our "Founders" a chapter dealing with that great theme by Professor John Bassett Moore, recently Assistant Secretary of State; later, Counsel for the Peace Commission at Paris; and now occupying the chair of International Law and Diplomacy in the School of Political Science, Columbia University, New York City.
