In judging these good people, however, it is wise to remember the terrible disadvantages under which they lived. They were really barbarians who posed as civilised people. Charlemagne and Otto the Great were called “Roman Emperors,” but they had as little resemblance to a real Roman Emperor (say Augustus or Marcus Aurelius) as “King” Wumba Wumba of the Upper Congo has to the highly educated rulers of Sweden or Denmark. They were savages who lived amidst glorious ruins but who did not share the benefits of the civilisation which their fathers and grandfathers had destroyed. They knew nothing. They were ignorant of almost every fact which a boy of twelve knows to-day. They were obliged to go to one single book for all their information. That was the Bible. But those parts of the Bible which have influenced the history of the human race for the better are those chapters of the New Testament which teach us the great moral lessons of love, charity and forgiveness. As a handbook of astronomy, zoölogy, botany, geometry and all the other sciences, the venerable book is not entirely reliable. In the twelfth century, a second book was added to the mediæval library, the great encyclopædia of useful knowledge, compiled by Aristotle, the Greek philosopher of the fourth century before Christ. Why the Christian church should have been willing to accord such high honors to the teacher of Alexander the Great, whereas they condemned all other Greek philosophers on account of their heathenish doctrines, I really do not know. But next to the Bible, Aristotle was recognized as the only reliable teacher whose works could be safely placed into the hands of true Christians. His works had reached Europe in a somewhat roundabout way. They had gone from Greece to Alexandria. They had then been translated from the Greek into the Arabic language by the Mohammedans who conquered Egypt in the seventh century. They had followed the Moslem armies into Spain and the philosophy of the great Stagirite (Aristotle was a native of Stagira in Macedonia) was taught in the Moorish universities of Cordova. The Arabic text was then translated into Latin by the Christian students who had crossed the Pyrenees to get a liberal education and this much travelled version of the famous books was at last taught at the different schools of northwestern Europe. It was not very clear, but that made it all the more interesting.
