It may save misunderstanding if a word or so be said here of the aim and scope of this book. It is written in relation to a previous work, Anticipations, Footnote: Published by Harper Bros.] and together with that and a small pamphlet, "The Discovery of the Future," Footnote: Nature, vol. lxv. (1901-2), and reprinted in the Smithsonian Report for 1902] presents a general theory of social development and of social and political conduct. It is an attempt to deal with social and political questions in a new way and from a new starting-point, viewing the whole social and political world as aspects of one universal evolving scheme, and placing all social and political activities in a defined relation to that; and to this general method and trend it is that the attention of the reader is especially directed. The two books and the pamphlet together are to be regarded as an essay in presentation. It is a work that the writer admits he has undertaken primarily for his own mental comfort. He is remarkably not qualified to assume an authoritative tone in these matters, and he is acutely aware of the many defects in detailed knowledge, in temper, and in training these papers collectively display. He is aware that at such points, for example, as the reference to authorities in the chapter on the biological problem, and to books in the educational chapter, the lacunar quality of his reading and knowledge is only too evident; to fill in and complete his design-notably in the fourth paper-he has had quite frankly to jerry-build here and there. Nevertheless, he ventures to publish this book.
