When the analysis of the folkways has been concluded it is necessary that it should be justified by a series of illustrations, or by a setting forth of cases in which the operation of the mores is shown to be what is affirmed in the analysis. Any such exposition of the mores in cases, in order to be successful, must go into details. It is in details that all the graphic force and argumentative value of the cases are to be found. It has not been easy to do justice to the details and to observe the necessary limits of space. The ethnographical facts which I present are not subsequent justification of generalizations otherwise obtained. They are selections from a great array of facts from which the generalizations were deduced. A number of other very important cases which I included in my plan of proofs and illustrations I have been obliged to leave out for lack of space. Such are: Demonism, Primitive Religion, and Witchcraft; The Status of Women; War; Evolution and the Mores; Usury; Gambling; Societal Organization and Classes; Mortuary Usages; Oaths; Taboos; Ethics; AEsthetics; and Democracy. The first four of these are written. I may be able to publish them soon, separately. My next task is to finish the sociology. W. G. SUMNER YALE UNIVERSITY With the reprinting of _Folkways_ it seems in place to inform the admirers of this book and of its author concerning the progress of Professor Sumner's work between 1907 and his death, in his seventieth year, in April, 1910. Several articles bearing on the mores, and realizing in part the programme outlined in the last paragraph of the foregoing Preface, have been published: "The Family and Social Change," in the _American Journal of Sociology_ for March, 1909 (14: 577-591); "Witchcraft," in the _Forum_ for May, 1909 (41: 410-423); "The Status of Women in Chaldea, Egypt, India, Judea, and Greece to the time of Christ," in the _Forum_ for August, 1909 (42: 113-136); "Mores of the Present and the Future," in the _Yale Review_ for November, 1909 (18: 233-245); and "Religion and the Mores," in the _American Journal of Sociology_ for March, 1910 (15: 577-591). Of these the first and last were presidential addresses before the American Sociological Society. All are included in Volume I (War and Other Essays) of a four-volume set of Sumner's writings, published since his death by the Yale University Press.
