The more we know of the Middle Ages the more do we realize how much they accomplished in every department of intellectual effort. Their development of the arts and crafts has never been equalled in the modern time. They made very great literature, marvellous architecture, sculpture that rivals the Greeks', painting that is still the model for our artists, surpassing illuminations; everything that they touched became so beautiful as to be a model for all the after time. They accomplished as much in education as they did in all the other arts, their universities had more students than any that have existed down to our own time, and they were enthusiastic students and their professors were ardent teachers, writers, observers, investigators. While we have been accustomed to think of them as neglecting science, their minds were occupied entirely with science. They succeeded in anticipating much more of our modern thought, and even scientific progress, than we have had any idea until comparatively recent years. The work of the later Middle Ages in mathematics is particularly strong, and was the incentive for many succeeding generations. Roger Bacon insisted that, without mathematics, there was no possibility of real advance in physical science. They had the right ideas in every way. While they were occupied more with the philosophical and ethical sciences than we are, these were never pursued to the neglect of the physical sciences in the strictest sense of that term. Is it not time that we should drop the foolish notions that are very commonly held because we know nothing about the Middle Ages--and, therefore, the more easily assume great knowledge--and get back to appreciate the really marvellous details of educational and scientific development which are so interesting and of so much significance at this time?
