The Middle Ages were "internationally minded." That sounds difficult, but wait until I explain it to you. We modern people are "nationally minded." We are Americans or Englishmen or Frenchmen or Italians and speak English or French or Italian and go to English and French and Italian universities, unless we want to specialise in some particular branch of learning which is only taught elsewhere, and then we learn another language and go to Munich or Madrid or Moscow. But the people of the thirteenth or fourteenth century rarely talked of themselves as Englishmen or Frenchmen or Italians. They said, "I am a citizen of Sheffield or Bordeaux or Genoa." Because they all belonged to one and the same church they felt a certain bond of brotherhood. And as all educated men could speak Latin, they possessed an international language which removed the stupid language barriers which have grown up in modern Europe and which place the small nations at such an enormous disadvantage. Just as an example, take the case of Erasmus, the great preacher of tolerance and laughter, who wrote his books in the sixteenth century. He was the native of a small Dutch village. He wrote in Latin and all the world was his audience. If he were alive to-day, he would write in Dutch. Then only five or six million people would be able to read him. To be understood by the rest of Europe and America, his publishers would be obliged to translate his books into twenty different languages. That would cost a lot of money and most likely the publishers would never take the trouble or the risk. Six hundred years ago that could not happen. The greater part of the people were still very ignorant and could not read or write at all. But those who had mastered the difficult art of handling the goose-quill belonged to an international republic of letters which spread across the entire continent and which knew of no boundaries and respected no limitations of language or nationality. The universities were the strongholds of this republic. Unlike modern fortifications, they did not follow the frontier. They were to be found wherever a teacher and a few pupils happened to find themselves together. There again the Middle Ages and the Renaissance differed from our own time. Nowadays, when a new university is built, the process (almost invariably) is as follows: Some rich man wants to do something for the community in which he lives or a particular religious sect wants to build a school to keep its faithful children under decent supervision, or a state needs doc-tors and lawyers and teachers. The university begins as a large sum of money which is deposited in a bank. This money is then used to construct buildings and laboratories and dormitories. Finally professional teachers are hired, entrance examinations are held and the university is on the way.
