This _Outline of History_ is an attempt to tell, truly and clearly, in one continuous narrative, the whole story of life and mankind so far as it is known to-day. It is written plainly for the general reader, but its aim goes beyond its use as merely interesting reading matter. There is a feeling abroad that the teaching of history considered as a part of general education is in an unsatisfactory condition, and particularly that the ordinary treatment of this “subject” by the class and teacher and examiner is too partial and narrow. But the desire to extend the general range of historical ideas is confronted by the argument that the available time for instruction is already consumed by that partial and narrow treatment, and that therefore, however desirable this extension of range may be, it is in practice impossible. If an Englishman, for example, has found the history of England quite enough for his powers of assimilation, then it seems hopeless to expect his sons and daughters to master universal history, if that is to consist of the history of England, plus the history of France, plus the history of Germany, plus the history of Russia, and so on. To which the only possible answer is that universal history is at once something more and something less than the aggregate of the national histories to which we are accustomed, that it must be approached in a different spirit and dealt with in a different manner. This book seeks to justify that answer. It has been written primarily to show that _history as one whole_ is amenable to a more broad and comprehensive handling than is the history of special nations and periods, a broader handling that will bring it within the normal limitations of time and energy set to the reading and education of an ordinary citizen. This outline deals with ages and races and nations, where the ordinary history deals with reigns and pedigrees and campaigns; but it will not be found to be more crowded with names and dates, nor more difficult to follow and understand. History is no exception amongst the sciences; as the gaps fill in, the outline simplifies; as the outlook broadens, the clustering multitude of details dissolves into general laws. And many topics of quite primary interest to mankind, the first appearance and the growth of scientific knowledge for example, and its effects upon human life, the elaboration of the ideas of money and credit, or the story of the origins and spread and influence of Christianity, which must be treated fragmentarily or by elaborate digressions in any partial history, arise and flow completely and naturally in one general record of the world in which we live.
