In common with all children of my age, I was brought up on American History and given no other history but American, year in and year out, year after year for eight or more years.

So far as I knew 1492 was the beginning of the world. Any events or characters before that time, reference to which I encountered by any chance, were put down in my mind in the same category with fairy-tales. Christ and His times, of which I heard only in Sunday-school, were to me mere fiction without reality. They were not mentioned in any history that I knew and therefore, so I thought, must belong not to a realm in time and space, but to a spiritual realm.

To give an American child only American History is as provincial as to teach a Texas child only Texas History. Patriotism is usually given as the reason for such history teaching. It only promotes a narrow-mindedness and an absurd conceit, based on utter ignorance of any other peoples and any other times—an intolerant egotism without foundation in fact. Since the World War it has become increasingly more and more important that American children should have a knowledge of other countries and other peoples in order that their attitude may be intelligent and unprejudiced.

As young as nine years of age, a child is eagerly inquisitive as to what has taken place in the ages past and readily grasps a concept of World History. Therefore, for many years Calvert School nine-year-old pupils have been taught World History in spite of academic and parental skepticism and antagonism. But I have watched the gradual drift toward adoption of this plan of history teaching, and with it an ever-increasing demand for a text-book of general history for young children. I have found, however, that all existing text-books have to be largely abridged and also supplemented by a running explanation and comment, to make them intelligible to the young child.

The recent momentous studies into the native intelligence of children show us what the average child at different ages can understand and what he cannot understand—what dates, figures of speech, vocabulary, generalities, and abstractions he can comprehend and what he cannot comprehend—and in the future all text-books will have to be written with constant regard for these intelligence norms. Otherwise, such texts are very likely to be “over the child’s head.” They will be trying to teach him some things at least that, in the nature of the case, are beyond him.

In spite of the fact that the writer has been in constant contact with the child mind for a great many years, he has found that whatever was written in his study had to be revised and rewritten each time after the lesson had been tried out in the class-room. Even though the first writing was in what he considered the simplest language, he has found that each and every word and expression has had to be subjected again and again to this class-room test to determine what meaning is conveyed. The slightest inverted phraseology or possibility of double meaning has oftentimes been misconstrued or found confusing. For instance, the statement that “Rome was on the Tiber River” has quite commonly been taken to mean that the city was literally built on top of the river, and the child has had some sort of fantastic vision of houses built on piles in the river. A child of nine is still very young—he may still believe in Santa Claus—younger in ideas, in vocabulary and in understanding than most adults appreciate—even though they be parents or teachers—and new information can hardly be put too simply.

So the topics selected have not always been the most important—but the most important that can be understood and appreciated by a child. Most political, sociological, economic, or religious generalities are beyond a child’s comprehension, no matter how simply told. After all, this History is only a preliminary story.

Excellent biographies and stories from general history have been written. But biographies from history do not give an historic outline. They do not give any outline at all for future filling in; and, indeed, unless they themselves are fitted into such a general historical scheme, they are nothing more than so many disconnected tales floating about in the child’s mind with no associations of time or space.

The treatment of the subject in this book is, therefore, chronological—telling the story of what has happened century by century and epoch by epoch, not by nations. The story of one nation is interrupted to take up that of another as different plots in a novel are brought forward simultaneously. This is in line with the purpose, which is to give the pupil a continuous view or panorama of the ages, rather than Greek History from start to finish, then, retracing the steps of time, Roman History, and so on. The object is to sketch the whole picture in outline, leaving the details to be gradually filled in by later study, as the artist sketches the general scheme of his picture before filling in the details. Such a scheme is as necessary to orderly classification of historical knowledge as is a filing system in any office that can function properly or even at all.

The Staircase of Time is to give a visual idea of the extent of time and the progressive steps in the History of the World. Each “flight” represents a thousand years, and each “step” a hundred—a century. If you have a spare wall, either in the play-room, attic, or barn such a Staircase of Time on a large scale may be drawn upon it from floor to reaching height and made a feature if elaborated with pictures or drawings of people and events. If the wall faces the child’s bed so much the better, for when lying awake in the morning or at any other time, instead of imagining fantastic designs on the wall-paper, he may picture the crowded events on the Staircase of Time. At any rate, the child should constantly refer either to such a Staircase of Time or to the Time Table as each event is studied, until he has a mental image of the Ages past.
