Pasteur, the great benefactor, whose discoveries did so much for all classes of society, should have been popular, but he was, on the contrary, extremely unpopular. The leading publicists of the day were influenced by some inexplicable sentiment and they made constant war on him. When, after several years of prodigious labor, Pasteur ventured to assert himself, they took advantage of his following the dictates of humanity in accepting all sorts of cases, curable or not, to spread a report that his treatment did not cure, but instead gave the disease which it was supposed to cure. Popular fury was aroused to such a height, that a monster mass meeting was held _against_ Pasteur. Louise Michel addressed this meeting with her customary vigor of speech and amidst frantic applause shouted this unqualified remark, '_Scientific questions should be settled by the people._'
