A Short History of England by G.K. Chesterton

It is a point of prestige with what is called the Higher Criticism in all branches to proclaim that certain popular texts and authorities are "late," and therefore apparently worthless. Two similar events are always the same event, and the later alone is even credible. This fanaticism is often in mere fact mistaken; it ignores the most common coincidences of human life: and some future critic will probably say that the tale of the Tower of Babel cannot be older than the Eiffel Tower, because there was certainly a confusion of tongues at the Paris Exhibition. Most of the mediaeval remains familiar to the modern reader are necessarily "late," such as Chaucer or the Robin Hood ballads; but they are none the less, to a wiser criticism, worthy of attention and even trust. That which lingers after an epoch is generally that which lived most luxuriantly in it. It is an excellent habit to read history backwards.

It is far wiser for a modern man to read the Middle Ages backwards from Shakespeare, whom he can judge for himself, and who yet is crammed with the Middle Ages, than to attempt to read them forwards from Caedmon, of whom he can know nothing, and of whom even the authorities he must trust know very little. If this be true of Shakespeare, it is even truer, of course, of Chaucer. If we really want to know what was strongest in the twelfth century, it is no bad way to ask what remained of it in the fourteenth. When the average reader turns to the "Canterbury Tales," which are still as amusing as Dickens yet as mediaeval as Durham Cathedral, what is the very first question to be asked? Why, for instance, are they called Canterbury Tales; and what were the pilgrims doing on the road to Canterbury? They were, of course, taking part in a popular festival like a modern public holiday, though much more genial and leisurely.
