First of all, remember that the people of the Middle Ages never thought of themselves as free-born citizens, who could come and go at will and shape their fate according to their ability or energy or luck. On the contrary, they all considered themselves part of the general scheme of things, which included emperors and serfs, popes and heretics, heroes and swashbucklers, rich men, poor men, beggar men and thieves. They accepted this divine ordinance and asked no questions. In this, of course, they differed radically from modern people who accept nothing and who are forever trying to improve their own financial and political situation.

To the man and woman of the thirteenth century, the world hereafter—a Heaven of wonderful delights and a Hell of brimstone and suffering—meant something more than empty words or vague theological phrases. It was an actual fact and the mediæval burghers and knights spent the greater part of their time preparing for it. We modern people regard a noble death after a well-spent life with the quiet calm of the ancient Greeks and Romans. After three score years of work and effort, we go to sleep with the feeling that all will be well.

But during the Middle Ages, the King of Terrors with his grinning skull and his rattling bones was man’s steady companion. He woke his victims up with terrible tunes on his scratchy fiddle—he sat down with them at dinner—he smiled at them from behind trees and shrubs when they took a girl out for a walk. If you had heard nothing but hair-raising yarns about cemeteries and coffins and fearful diseases when you were very young, instead of listening to the fairy stories of Andersen and Grimm, you, too, would have lived all your days in a dread of the final hour and the gruesome day of Judgment. That is exactly what happened to the children of the Middle Ages. They moved in a world of devils and spooks and only a few occasional angels. Sometimes, their fear of the future filled their souls with humility and piety, but often it influenced them the other way and made them cruel and sentimental. They would first of all murder all the women and children of a captured city and then they would devoutly march to a holy spot and with their hands gory with the blood of innocent victims, they would pray that a merciful heaven forgive them their sins. Yea, they would do more than pray, they would weep bitter tears and would confess themselves the most wicked of sinners. But the next day, they would once more butcher a camp of Saracen enemies without a spark of mercy in their hearts.

Of course, the Crusaders were Knights and obeyed a somewhat different code of manners from the common men. But in such respects the common man was just the same as his master. He, too, resembled a shy horse, easily frightened by a shadow or a silly piece of paper, capable of excellent and faithful service but liable to run away and do terrible damage when his feverish imagination saw a ghost.

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.

With the help of the Bible and Aristotle, the most brilliant men of the Middle Ages now set to work to explain all things between Heaven and Earth in their relation to the expressed will of God. These brilliant men, the so-called Scholiasts or Schoolmen, were really very intelligent, but they had obtained their information exclusively from books, and never from actual observation. If they wanted to lecture on the sturgeon or on caterpillars, they read the Old and New Testaments and Aristotle, and told their students everything these good books had to say upon the subject of caterpillars and sturgeons. They did not go out to the nearest river to catch a sturgeon. They did not leave their libraries and repair to the backyard to catch a few caterpillars and look at these animals and study them in their native haunts. Even such famous scholars as Albertus Magnus and Thomas Aquinas did not inquire whether the sturgeons in the land of Palestine and the caterpillars of Macedonia might not have been different from the sturgeons and the caterpillars of western Europe.

When occasionally an exceptionally curious person like Roger Bacon appeared in the council of the learned and began to experiment with magnifying glasses and funny little telescopes and actually dragged the sturgeon and the caterpillar into the lecturing room and proved that they were different from the creatures described by the Old Testament and by Aristotle, the Schoolmen shook their dignified heads. Bacon was going too far. When he dared to suggest that an hour of actual observation was worth more than ten years with Aristotle and that the works of that famous Greek might as well have remained untranslated for all the good they had ever done, the scholiasts went to the police and said, “This man is a danger to the safety of the state. He wants us to study Greek that we may read Aristotle in the original. Why should he not be contented with our Latin-Arabic translation which has satisfied our faithful people for so many hundred years? Why is he so curious about the insides of fishes and the insides of insects? He is probably a wicked magician trying to upset the established order of things by his Black Magic.” And so well did they plead their cause that the frightened guardians of the peace forbade Bacon to write a single word for more than ten years. When he resumed his studies he had learned a lesson. He wrote his books in a queer cipher which made it impossible for his contemporaries to read them, a trick which became common as the Church became more desperate in its attempts to prevent people from asking questions which would lead to doubts and infidelity.
