38 DE # 40 A PREFACE In this volume I have gathered certain addresses I made before the American Historical Association, the University of Oxford, the University of Berlin, and the Sorbonne at Paris, together with six essays I wrote for The Outlook, and one that I wrote for The Century. In these addresses and essays I have discussed not merely literary but also historical and scientific subjects, for my thesis is that the domain of literature must be ever more widely extended over the domains of history and science. nothing which in this preface I can say to elaboThere is rate or emphasize what I have said on this subject in the essays themselves.
