demands a detailed knowledge of all these dates because otherwise we could not fix the great lines of development. That task belongs to the professional historians. But the average man is not a professor of history. For him history has only one mission and that is to provide him with such an amount of historical knowledge as is necessary in order to enable him to form an independent opinion on the political affairs of his own country. The man who wants to become a professor of history can devote himself to all the details later on. Naturally he will have to occupy himself even with the smallest details. Of course our present teaching of history is not adequate to all this. Its scope is too vast for the average student and too limited for the student who wishes to be an historical expert.
