      The Popes and Science / The History of the Papal Relations to Science During the Middle Ages and Down to Our Own Time

      PREFACE

      A new edition of this volume being called for, I take the occasion to place it under the aegis of the University of Notre Dame as a slight token of gratitude for the formal recognition of the work by the faculty of that institution, and bind this Notre Dame edition in the University colors, blue and gold.

      There is much more readiness at the present time to accept the conclusions with regard to the relations of the Popes and science here suggested than there was when the book was first published. Knowledge of the general history of science has grown very materially in the last ten years. Every increase in historical knowledge has shown more and more clearly how utterly without foundation were many ideas which had been very commonly accepted, particularly in English-speaking countries, on the subjects here discussed. The supposed opposition to the development of science on the part of the Popes and the Church is now readily seen to have had no existence in reality, and popular notions on the subject were due entirely to ignorance of the history of science. There was supposed to be no scientific development and no nature study until quite recent times. The generations immediately preceding ours knew of none, and therefore concluded there must have been none. They went even farther, and felt that since there had been none, there must be some special reason for this lacuna in human progress. The Church and the Popes were the favorite scapegoats for human failings, so they were blamed. Now we know that there was a magnificent development of science, not only in the Renaissance period under the fostering care of the Popes and ecclesiastics, but also during the old university times. What has come above all to be recognized is that the medieval universities were scientific universities. They paid more attention to the ethical and philosophical sciences than we do, but they devoted a great deal of time to mathematics and the physical sciences. Mr. Huxley, in his inaugural address as Rector of the University of Aberdeen, declared thirty years ago that the curriculum of these old universities was better calculated to develop the many-sided mind of man than the curriculum of any modern university. Above all, in surgery and in medicine they did magnificent work. Anaesthesia, antisepsis, and the natural methods of cure were all anticipated in the medieval time. At the International Congress of Medicine last summer, a section on the history of medicine was organized because it has come to be recognized that very much that is even of practical value can be learned from medical history.

      The fact of the matter is that during the eighteenth and early nineteenth centuries there was a great decadence of interest in scholarship and true education. There is a distinct descent in human culture at this time. Education was at its lowest ebb, hospitals {iv} were the worst ever built, art and architecture were neglected, and human liberty was so shackled that the French Revolution was needed to lift the fetters from men's minds as well as bodies. They, in their ignorance, spoke slightingly of old-time scholars. During the past century we have come to a better knowledge of the Middle Ages, and he is indeed a backward student of history who now thinks of them as "dark." Our millionaires have gathered, at immense expense, magnificent examples of the arts and crafts and beautiful books of the medieval and Renaissance periods. Our binders imitate their books, our artists study their works, we have revived their architecture and literature, are imitating their social ideas until, instead of "the dark ages," we have come to think of them as "the bright ages." What is not generally realized is that they are just as bright in science as they were in art, architecture, literature, and the arts and crafts.

      Literally, the Popes were as much the patrons of science as they were of the arts. Professor White's book, "The Warfare of Science with Theology," like Professor Draper's "History of the Conflict Between Religion and Science," are now seen to represent simply an interesting evidence of the lack of real knowledge of the history of science and, above all, complete ignorance of details as to the genuine accomplishment of the olden time on the part of the generation by which they were taken seriously. Being quite sure that there was no science to speak of in the older times, these writers gathered every possible reference, found anywhere in secondary authorities, for they almost never went to the original documents, as evidence for their preconceived conviction that the Church must have suppressed science whenever that was possible. The real history of science was ignored. As soon as that is known there is no further question of Church opposition, but, on the contrary, of the extent of ecclesiastical patronage and encouragement of science.

      Some of this very different story is told only too incompletely in this volume. It would take many volumes to give all the details of it. Readers will find here at least such references to the actual documentary history as will form a good basis for definite knowledge of the genuine relations of the Popes to science. The series of new appendices in this edition, especially those on Papal Physicians, Science in America, and the original Papal documents so often quoted, but seldom seen entire, is meant to supply material for the correction of many false notions that are unfortunately prevalent. They present historical matter that has not been readily available hitherto in English-speaking countries and that has nowhere been easy of access in the form here given.

      Appendix VII by Rev. Father Leahy on The Fathers of The Church and Science presents a controverted point of history to persuasion. Appendix IX shows how amusing and amazing was Professor Draper's lack of knowledge of the history of science and above all of medicine and surgery when he wrote his "histories" that were so widely read and accepted because we in America knew no better for the moment.

      PREFACE

      For years, as a student and physician, I listened to remarks from teachers and professional friends as to the opposition of the Popes to science, until finally, much against my will, I came to believe that there had been many Papal documents issued, which intentionally or otherwise hampered the progress of science. Interest in the history of medicine led me to investigate the subject for myself. To my surprise, I found that the supposed Papal opposition to science was practically all founded on an exaggeration of the significance of the Galileo incident. As a matter of history, the Popes were as liberal patrons of science as of art. In the Renaissance period, when their patronage of Raphael and Michel Angelo and other great artists did so much for art, similar relations to Columbus, Eustachius, and Caesalpinus, and later to Steno and Malpighi, our greatest medical discoverers, had like results for science. The Papal Medical School was for centuries the greatest medical school in Europe, and its professors were the most distinguished medical scientists of the time. This is a perfectly simple bit of history that anyone may find for himself in any reliable history of medicine. The medical schools were the scientific departments of the universities practically down to the nineteenth century. In them were studied botany, zoology and the biological sciences generally, chemistry, physics, mineralogy and even astronomy, because of the belief that the stars influenced human constitutions. The Popes in fostering medical schools (there were four of them in the Papal dominions, and two of them, Bologna and Rome, were the greatest medical schools for several centuries) were acting as wise and beneficent patrons of science. Many of the greatest scientists of the Middle Ages were clergymen. Some of the greatest of them were canonized as saints. Albertus Magnus and Thomas Aquinas are typical examples. At least one Pope had been a distinguished scientist before being elected to the Papacy. For seven centuries the Popes selected as their physicians the greatest medical scientists of the {vi} time, and the list of Papal physicians is the worthiest series of names connected by any bond in the history of medicine, far surpassing in scientific import even the roll of the faculty of any medical school.

      In a word, I failed to find any trace of Papal opposition to true science in any form. On the contrary, I found abundant evidence of their having been just as liberal and judicious patrons of science as they were of art and education in all forms. I found also that those who write most emphatically about Papal opposition to science, know nothing at all of the history of science, and above all of medicine and of surgery, during three very precious centuries. Because they know nothing about it they think there was none, and go out of their way to find a reason for its absence, while all the time there is a wondrous series of chapters of science for those who care to look for them. This is the story that I have tried to tell in this book.

      This material is, I think, gathered into compact form for the first time. No one knows better than I do how many
