I have dwelt on the medical side of these universities mainly, of course, because this is more familiar to me as a historian of medicine than their work in other scientific departments, but also to a great extent because the medical schools gathered unto themselves nearly all the scientific knowledge of the time. Botany, mineralogy, climatology, meteorology were all studied for the sake of what could be learned from them for the benefit of medicine. Even astronomy which was then the old astrology, was cultivated seriously, because of the supposed effect of the stars on human constitutions. For this we surely cannot blame these mediaeval students of science since four centuries later Galileo and even Kepler were still making horoscopes for their patrons and laying down laws from astronomy that were supposed to be applicable to medicine. Even Copernicus studied astronomy and medicine side by side and this combination of studies was not at all infrequent. The medical schools, then, are the real index of {142} the serious interest of the mediaeval universities in science. Our scientific departments in modern universities have developed other interests, because of various applications that these have to life and its concerns. Always in scientific universities applied science is sure to encroach upon the domain of pure science, and no one knows that better than we do, for we have been bewailing the presence of machine shops and boiler factories on the university grounds. The old universities did not teach applied mechanics or engineering, but that does not mean that these subjects were not taught. There were special technical schools conducted by the gilds by means of apprenticeship and the journeyman training, which enabled them to teach those who cared to have it all the knowledge necessary for construction work of various kinds. The wonderful architectural engineering exhibited in the cathedrals, university buildings, town halls and castles of this time, and the magnificent bridges, some of which are still in existence, show us that the technical subjects were by no means neglected. [Footnote 9] Our mediaeval forefathers in education had the wisdom not to let the technical subjects interfere with pure science too much, as they inevitably do whenever the two are brought too closely together. Culture is always overshadowed by the practical, but not to the ultimate benefit of the race. [Footnote 9: See Address on "Ideal Education of the Masses."]
