This roused Voltaire. He did not venture to attack the king, but he assailed M. Maupertuis again, anonymously, but with greatly increased venom. A brief pamphlet appeared, entitled, “The Diatribe of Doctor Akakia, Physician to the Pope.” It was a merciless satire against M. Maupertuis. Voltaire was entirely unscrupulous, and was perfect master of the language of sarcasm. No moral principle restrained him from exaggerating, misrepresenting, or fabricating any falsehoods which would subserve his purpose. M. Maupertuis was utterly overwhelmed with ridicule. The satire was so keen that few could read it without roars of laughter. Voltaire, the king’s guest, was thus exposing to the contempt of all Europe the president of the Berlin Academy, the reputation of which Academy was dear to the king above almost every thing else. An edition of the pamphlet was printed in Holland, and copies were scattered all over Berlin. Another edition was published in Paris, where thirty thousand copies were eagerly purchased.!
