History of the Conflict Between Religion and Science

by John William Draper

But it was not only in Italy, in Germany, in England, in France, that this great movement in mathematics was witnessed; Scotland had added a new gem to the intellectual diadem with which her brow is encircled, by the grand invention of Logarithms, by Napier of Merchiston. It is impossible to give any adequate conception of the scientific importance of this incomparable invention. The modern physicist and astronomer will most cordially agree with Briggs, the Professor of Mathematics in Gresham College, in his exclamation: "I never saw a book that pleased me better, and that made I me more wonder!" Not without reason did the immortal Kepler regard Napier "to be the greatest man of his age, in the department to which he had applied his abilities." Napier died in 1617. It is no exaggeration to say that this invention, by shortening the labors, doubled the life of the astronomer.

But here I must check myself. I must remember that my present purpose is not to give the history of mathematics, but to consider what science has done for the advancement of human civilization. And now, at once, recurs the question, How is it that the Church produced no geometer in her autocratic reign of twelve hundred years?

With respect to pure mathematics this remark may be made: Its cultivation does not demand appliances that are beyond the reach of most individuals. Astronomy must have its observatory, chemistry its laboratory; but mathematics asks only personal disposition and a few books. No great expenditures are called for, nor the services of assistants. One would think that nothing could be more congenial, nothing more delightful, even in the retirement of monastic life.

Shall we answer with Eusebius, "It is through contempt of such useless labor that we think so little of these matters; we turn our souls to the exercise of better things?" Better things! What can be better than absolute truth? Are mysteries, miracles, lying impostures, better? It was these that stood in the way!

The ecclesiastical authorities had recognized, from the outset of this scientific invasion, that the principles it was disseminating were absolutely irreconcilable with the current theology. Directly and indirectly, they struggled against it. So great was their detestation of experimental science, that they thought they had gained a great advantage when the Accademia del Cimento was suppressed. Nor was the sentiment restricted to Catholicism. When the Royal Society of London was founded, theological odium was directed against it with so much rancor that, doubtless, it would have been extinguished, had not King Charles II. given it his open and avowed support. It was accused of an intention of "destroying the established religion, of injuring the universities, and of upsetting ancient and solid learning."

THE ROYAL SOCIETY OF LONDON. We have only to turn over the pages of its Transactions to discern how much this society has done for the progress of humanity. It was incorporated in 1662, and has interested itself in all the great scientific movements and discoveries that have since been made. It published Newton's "Principia;" it promoted Halley's voyage, the first scientific expedition undertaken by any government; it made experiments on the transfusion of blood, and accepted Harvey's discovery of the circulation. The encouragement it gave to inoculation led Queen Caroline to beg six condemned criminals for experiment, and then to submit her own children to that operation. Through its encouragement Bradley accomplished his great discovery, the aberration of the fixed stars, and that of the nutation of the earth's axis; to these two discoveries, Delambre says, we owe the exactness of modern astronomy. It promoted the improvement of the thermometer, the measure of temperature, and in Harrison's watch, the chronometer, the measure of time. Through it the Gregorian Calendar was introduced into England, in 1752, against a violent religious opposition. Some of its Fellows were pursued through the streets by an ignorant and infuriated mob, who believed it had robbed them of eleven days of their lives; it was found necessary to conceal the name of Father Walmesley, a learned Jesuit, who had taken deep interest in the matter; and, Bradley happening to die during the commotion, it was declared that he had suffered a judgment from Heaven for his crime!

THE ROYAL SOCIETY OF LONDON. If I were to attempt to do justice to the merits of this great society, I should have to devote many pages, to such subjects as the achromatic telescope of Dollond; the dividing engine of Ramsden, which first gave precision to astronomical observations, the measurement of a degree on the earth's surface by Mason and Dixon; the expeditions of Cook in connection with the transit of Venus; his circumnavigation of the earth; his proof that scurvy, the curse of long sea-voyages, may be avoided by the use of vegetable substances; the polar expeditions; the determination of the density of the earth by Maskelyne's experiments at Scheliallion, and by those of Cavendish; the discovery of the planet Uranus by Herschel; the composition of water by Cavendish and Watt; the determination of the difference of longitude between London and Paris; the invention of the voltaic pile; the surveys of the heavens by the Herschels; the development of the principle of interference by Young, and his establishment of the undulatory theory of light; the ventilation of jails and other buildings; the introduction of gas for city illumination; the ascertainment of the length of the seconds-pendulum; the measurement of the variations of gravity in different latitudes; the operations to ascertain the curvature of the earth; the polar expedition of Ross; the invention of the safety-lamp by Davy, and his decomposition of the alkalies and earths; the electro-magnetic discoveries of Oersted and Faraday; the calculating-engines of Babbage; the measures taken at the instance of Humboldt for the establishment of many magnetic observatories; the verification of contemporaneous magnetic disturbances over the earth's surface. But it is impossible, in the limited space at my disposal, to give even so little as a catalogue of its Transactions. Its spirit was identical with that which animated the Accademia del Cimento, and its motto accordingly was "Nullius in Verba." It proscribed superstition, and permitted only calculation, observation, and experiment.

INFLUENCE OF SCIENCE. Not for a moment must it be supposed that in these great attempts, these great Successes, the Royal Society stood alone. In all the capitals of Europe there were Academies, Institutes, or Societies, equal in distinction, and equally successful in promoting human knowledge and modern civilization.

THE ECONOMICAL INFLUENCES OF SCIENCE.

The scientific study of Nature tends not only to correct and ennoble the intellectual conceptions of man; it serves also to ameliorate his physical condition. It perpetually suggests to him the inquiry, how he may make, by their economical application, ascertained facts subservient to his use.
