In opening this meeting of the American Society of International Law, which I hope will be the first of many meetings in unbroken succession to continue long after we personally have ceased to take part in affairs, let me welcome you to the beginning of your labors for a more thorough understanding of this important and fascinating subject. It is impossible that the human mind should be addressed to questions better worth its noblest efforts, offering a greater opportunity for usefulness in the exercise of its powers, or more full of historical and contemporary interest, than in the field of international rights and duties. The change in the theory and practice of government which has marked the century since the establishment of the American Union has shifted the determination of great questions of domestic national policy from a few rulers in each country to the great body of the people, who render the ultimate decision under all modern constitutional governments. Coincident with that change the practice of diplomacy has ceased to be a mystery confined to a few learned men who strive to give effect to the wishes of personal rulers, and has become a representative function answering to the opinions and the will of the multitude of citizens, who themselves create the relations between states and determine the issues of friendship and estrangement, of peace and war. Under the new system there are many dangers from which the old system was free. The rules and customs which the experience of centuries had shown to be essential to the maintenance of peace and good understanding between nations have little weight with the new popular masters of diplomacy; the precedents and agreements of opinion which have carried so great a part of the rights and duties of nations toward each other beyond the pale of discussion are but little understood. The education of public opinion, which should lead the sovereign people in each country to understand the definite limitations upon national rights and the full scope and responsibility of national duties, has only just begun. Information, understanding, leadership of opinion in these matters, so vital to wise judgment and right action in international affairs, are much needed. This society may serve as a collegium, in the true sense of the word, in which all who choose to seek a broader knowledge of the law that governs the affairs of nations may give each to the other the incitement of earnest and faithful study and may give to the great body of our countrymen a clearer view of their international rights and responsibilities.
