The biographer of Vesalius, who evidently shared the prejudices of the people, had exerted himself strenuously to disprove the calumny attached to the name of the great anatomist. He, like the rest, was blinded by that vulgar egotism which clamorously prefers the interests of individuals to those of society,--egotism no less short-sighted than vulgar, for the large and abstract interests cared for by science are precisely those which shall ultimately affect the greatest number of individuals; and no less inconsequent than short-sighted, since no one hesitates to ruin entire hosts of individuals upon the faintest chance of promoting the material interests of society. A stock company may immolate hundreds during the construction of a Panama railroad--a sovereign sacrifice thousands in the contest for a Crimean peninsula; the hue and cry only begins when the savant modestly begs permission to utilize a single life for the advancement of science. He is execrated as a monster, and burned alive in expiation of his crime. Absurd inconsistency, trivial superstition! from which it is time that at least the scientific world were emancipated. Long enough has the ignorant rabble exercised brute tyranny over intellects towering above its comprehension. The time for concession is past, the moment has arrived for the savant to assume the sway that rightfully devolves upon him and declare the confiscation of all claims to the supreme interest of the search after truth. For my part, therefore, so far from blaming Vesalius because he had dissected a living man, I should have accorded him most profound reverence for this proof of elevation above ordinary prejudice. And the more I thought over the matter, the more I became convinced that the accusation was well founded, that the deed had really been performed, which moral cowardice alone induced the glorious criminal to disavow.
