The Warfare of Science

by Andrew Dickson White

From the outset Vesalius proved himself a master. In the search for real knowledge he braved the most terrible dangers. Before his time the dissection of the human subject was thought akin to sacrilege. Occasionally an anatomist, like Mundinus, had given some little display with such a subject; but, for the purposes of investigation, such dissection was forbidden. [111] As we have already seen, even such men in the early Church as Tertullian and St. Augustine held anatomy in abhorrence, and Boniface VIII. interdicted dissection as sacrilege.

Through this sacred conventionalism Vesalius broke without fear. Braving ecclesiastical censure and popular fury, he studied his science by the only method that could give useful results. No peril daunted him. To secure the material for his investigations, he haunted gibbets and charnel-houses; in this search he risked alike the fires of the Inquisition and the virus of the plague. First of all men he began to place the science of human anatomy on its solid, modern foundations—on careful examination and observation of the human body. This was his first great sin, and it was soon aggravated by one considered even greater.

Perhaps the most unfortunate thing that has ever been done for Christianity is the tying it to forms of science which are doomed and gradually sinking. Just as, in the time of Roger Bacon, excellent but mistaken men devoted all their energies to binding Christianity to Aristotle; just as, in the time of Reuchlin and Erasmus, they insisted on binding Christianity to Thomas Aquinas: so, in the time of Vesalius, such men made every effort to link Christianity to Galen.

The cry has been the same in all ages; it is the same which we hear in this age for curbing scientific studies—the cry for what is called "sound learning." Whether standing for Aristotle against Bacon, or Aquinas against Erasmus, or Galen against Vesalius, or making mechanical Greek verses at Eton instead of studying the handiwork of the Almighty, or reading Euripides with translations instead of Lessing and Goethe in the original, the cry always is for "sound learning." The idea always is that these studies are safe.

At twenty-eight years of age Vesalius gave to the world his great work on human anatomy. With it ended the old and began the new. Its researches, by their thoroughness, were a triumph of science; its illustrations, by their fidelity, were a triumph of art.

To shield himself, as far as possible, in the battle which he foresaw must come, Vesalius prefaced the work by a dedication to the Emperor Charles V. In this dedicatory preface he argues for his method, and against the parrot repetitions of the mediæval text-books; he also condemns the wretched anatomical preparations and specimens made by physicians who utterly refused to advance beyond the ancient master.

The parrot-like repeaters of Galen gave battle at once. After the manner of their time, their first missiles were epithets; and, the almost infinite magazine of these having been exhausted, they began to use sharper weapons—weapons theologic.

At first the theologic weapons failed. A conference of divines having been asked to decide whether dissection of the human body is sacrilege, gave a decision in the negative. The reason is simple: Charles V. had made Vesalius his physician, and could not spare him. But, on the accession of Philip II. of Spain, the whole scene changed. That most bitter of bigots must of course detest the great innovator.

A new weapon was now forged. Vesalius was charged with dissecting living men, [112] and, either from direct persecution, as the great majority of authors assert, or from indirect influences, as the recent apologists for Philip II. allow, Vesalius became a wanderer. On a pilgrimage to the Holy Land to atone for his sin, he was shipwrecked, and in the prime of his life and strength he was lost to this world.
