A glance at the Oncken series will convince any one how very difficult it is to attain even approximately to a true perspective of world history under the symposial plan. Thus one finds in this series, to cite but a single illustration of disproportionate treatment, that various relatively insignificant periods of modern German history are allowed to fill bulky volumes where a true perspective would have relegated them to mere chapters. It is only from a very prejudiced modern standpoint that the history of Frederick II can be thought worth greater space than the entire history of the Greek world. Where such inconsistencies are permitted there is a danger that the alleged world history will become rather the history of a single nation in its relations to other nations, past and present, than an impartial presentation of the history of nations as a whole. In the present work an attempt has been made to avoid the pitfalls of one-man treatment on the one hand, and of ill-adjusted specialist treatment on the other. We have made sure of presenting special knowledge by drawing upon the specialists of every field, and letting them present their information in their own words; but, at the same time, we have attempted to avoid the prejudiced view from which the specialist is least of all men free, by presenting the counter views of various students wherever there is failure of agreement among those best competent to judge. The authorities on whom historial compositions are necessarily based, and who in other works are merely cited by name, or at most by volume and page reference, are here quoted in detail in their own words wherever practicable, always with full credit to the author, and with exact reference to the work from which the excerpt is taken. Such authorities are quoted, not merely from histories in English, but from the entire range of historical writings of all ages. It is hoped that few important names are overlooked. The aggregate number of different works thus quoted (not merely cited) will be about one thousand. These quotations vary in length from illuminative paragraphs to excerpts of many pages, averaging perhaps about two thousand words each. Some fifteen hundred of such extensive quotations are made from foreign languages, and by far the greater number of these have been translated from the originals expressly for the present work, thus representing matter never before accessible to the reader of English. The languages represented in this list of important historical works of foreign origin include practically all the tongues of civilised nations, ancient and modern,--Egyptian, Babylonian, Assyrian, Arabic, Syriac, Persian, Chinese, Japanese, and the entire range of European languages from Greek, Latin, and Russian to Italian, Spanish, Portuguese, French, Dutch, German, and Scandinavian. From all of these the original words of the various authors have been translated into the most literal English consistent with our idiom.
