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.”

By this time everybody was talking about microbes, and a shop on the boulevards announced an exhibition of them.  They used what is known as a solar microscope and threw on a screen, suitably enlarged, the animalculae which grow in impure water, the larvae of mosquitoes, and other insects, which bear about the same relation to microbes that an elephant does to a flea.  I went into this establishment, and saw the plain people with their wives looking at the exhibition very seriously and really believing that they saw the famous microbes.  One of them near me said, with a knowing air, “What won’t science do next?”

I was indignant, and I had all I could do to keep from saying:  “They are fooling you.  What they are showing you is not Science, at the most only its antechamber.  As for you who are deceiving these naive good people, you are only impostors.”

But I kept still; I would only have succeeded in getting thrown out.  But I said to myself—­and I still say—­“Why not enlighten these people, who obviously want light?” It is impossible to teach them science, but it should be possible to make them at least comprehend what science is, for they have no idea of it now.  They do not know—­in this era when they are constantly talking about their rights and urged to demand more wages and less work—­that there are young people who are spending their best years and leading a precarious existence, working day and night, without hope of personal profit, with no other end in view besides the hope of discovering new facts from which humanity may benefit at some time in the future.  They do not know that all the benefits of civilization which they carelessly enjoy are the result of the long, painful and enormous work of the thinkers whom they regard as idlers and visionaries who grow rich from the sweat of the toilers.  In a word, they should be taught to give respect to what is worthy of it.

It is true that there are scientific congresses, but these are serious gatherings which attract only the select few.  It should be possible to interest everybody, and in order to make scientific meetings interesting we should use motion pictures and concerts.
