Goldwin Smith, in his Lecture on History, says there can be no philosophy of history until we realize the unity of the human race and that history must be studied as a whole. Twenty years ago, at the Johns Hopkins University, I began to teach Local History, as representative of Universal History. I began with New England Village Communities, with Plymouth Plantations, Salem and the Massachusetts Bay Towns, those little republics which seemed to me the very protoplasm of State life. The survival, continuity or revival of old Germanic forms of village settlement, with common fields and town commons, impressed my imagination and interested my students. They carried this kind of study into this State of Maryland and original papers by Maryland boys were published upon such subjects as Parishes, Manors, and other local institutions. These lines of inquiry were extended down the Atlantic seaboard to Virginia and the Carolinas. Gradually the field of interest has been widened from towns, plantations, parishes, and counties until now the constitutional, economic and educational history of entire States is in review or contemplation. While I still believe in Local History and in limited subjects of student research, I now recognize more fully than I used to do, the importance of General History, especially for college students and college graduates in the early part of their course. After all, the great fact in History, as well as in Geography, is that the world is round. You must recognize all human experience on this globe as parts of one great whole, just as you recognize that the continents and outlying islands are but related parts of one vast geographical system. In every properly arranged course of school and college instruction in the domain of History, this doctrine of unity ought to be taken for granted. It is like the doctrine of divine unity in theology or in nature, like the sun in our heavens. It gives light and rationality to any and every course of study.
