As for his mind, it is one of the most cultivated that we have. He knows many things. He invented some of them. He was not even 250 years old when he studied, as is customary, at the most celebrated[4] colleges of his planet, where he managed to figure out by pure willpower more than 50 of Euclid's propositions. That makes 18 more than Blaise Pascal, who, after having figured out 32 while screwing around, according to his sister's reports, later became a fairly mediocre geometer[5] and a very bad metaphysician. Towards his 450th year, near the end of his infancy, he dissected many small insects no more than 100 feet in diameter, which would evade ordinary microscopes. He wrote a very curious book about this, and it gave him some income. The mufti of his country, an extremely ignorant worrywart, found some suspicious, rash[6], disagreeable, and heretical propositions in the book, smelled heresy, and pursued it vigorously; it was a matter of finding out whether the substantial form of the fleas of Sirius were of the same nature as those of the snails. Micromegas gave a spirited defense; he brought in some women to testify in his favor; the trial lasted 220 years. Finally the mufti had the book condemned by jurisconsults who had not read it, and the author was ordered not to appear in court for 800 years[7]. [4] In place of "the most celebrated" that one finds in the first edition, subsequent editions read "some jesuit." B. [5] Pascal became a very great geometer, not in the same class as those that contributed to the progress of science with great discoveries, like Descartes, Newton, but certainly ranked among the geometers, whose works display a genius of the first order. K. [6] The edition that I believe to be original reads: "rash, smelling heresy." The present text is dated 1756. B. [7] Mr. Voltaire had been persecuted by the theatin Boyer for having stated in his _Letters on the English_ that our souls develop at the same time as our organs, just like the souls of animals. K.
