176 world does not change." But I hope that you will not pay much attention to such talk. You see, it took our ancestors almost a million years to learn how to walk on their hind legs. Other centuries had to go by before their animal-like grunts developed into an understandable language. Writing — the art of preserving our ideas for the benefit of future generations, without which no progress is possible — was invented only four thousand years ago. The idea of turning the forces of nature into the obedient servants of man was quite new in the days of your own grandfather. It seems to me, therefore, that we are making progress at an unheard-of rate of speed. Perhaps we have paid a little too much attention to the mere physical comforts of life. That will change in due course of time and we shall then attack the problems which are not related to health and to wages and plumbing and machinery in general.

But please do not be too sentimental about the "good old days." Many people who only see the beautiful churches and the great works of art which the Middle Ages have left behind grow quite eloquent when they compare our own ugly civilisation with its hurry and its noise and the evil smells of back-firing motor trucks with the cities of a thousand years ago. But these mediæval churches were invariably surrounded by miserable hovels compared to which a modern tenement house stands forth as a luxurious palace. It is true that the noble Lancelot and the equally noble Parsifal, the pure young hero who went in search of the Holy Grail, were not bothered by the odor of gasoline. But there were other smells of the barn-yard variety — odors of decaying refuse which had been thrown into the street — of pig-sties surrounding the Bishop's palace — of unwashed people who had inherited their coats and hats from their grandfathers and who had never learned the blessing of soap. I do not want to paint too unpleasant a picture. But when you read in the ancient chronicles that the King of France, looking out of the windows of his palace, fainted at the stench caused by the pigs rooting in the streets of Paris, when an ancient manuscript recounts a few details of an epidemic of the plague or of small-pox, then you begin to
