At length the storm broke forth. The infidelity which had danced and smiled, and made _calembourgs_ and scoffed, in the full-dress circles of the nobles; made its appearance in the streets and highways, in rags and riot, with the axe for the pen, and blood for the ink, and trampled the whole polished race of scoffers in the mire of Revolution. The _Encyclopédie_ was the great text-book of the literary faction, and Diderot and D'Alembert were the editors of its first seven volumes--D'Alembert writing the preliminary discourse upon the progress of the sciences. But the latter mixed caution with his courage; for on the issue of the government prohibition of the work, he abandoned the editorship and left it to Diderot. At length, in 1752, the King of Prussia, who, with all his fame, had the weakness of being emulous of French flattery, offered him an appointment at Berlin, with an allowance of five hundred pounds a-year, and the reversionary office of president of the academy. But this royal offer he refused, on the ground of his reluctance to quit Paris, and the fear that the employment would be inconsistent with his freedom. At this period his fixed income seemed to be about seventy pounds a-year; yet, when we suffer ourselves to be astonished at the apparent magnanimity of the refusal, we are to remember that this sum, a hundred years ago, and in Paris, would be about equivalent to two hundred pounds a-year in England at the present day; that, like all Frenchmen, he hated Germany; that Frederic's dealings with Voltaire gave by no means a favourable specimen of his friendships; and that, to a Frenchman of that day, Paris was all the world. But, ten years after, the Empress Catharine made him the much more tempting offer of the tutorship of her son, afterwards the unfortunate Emperor Paul. The salary was to be magnificent, no less than four thousand pounds a-year; still he refused the offer, and preferred remaining in Paris. Whether we are to applaud his magnanimity, or blame his habits, on this occasion, may fairly be a question. The possession of the four thousand pounds a-year, even if it were limited to the period of tuition, would have made him opulent; and his opulence would undoubtedly have given him the means of extensive benevolence, of relieving private distress, of assisting his less fortunate literary brethren, of promoting public objects, and ultimately, perhaps, of founding some valuable institution which might last for ages. But D'Alembert, and men like him, seem to live only for themselves. It would have cost him an absence from Paris for a certain period to have obtained this power of public good; and he preferred living without it, and haunting, night after night, the coteries of the old blue-stockings who kept open house for the evening gossipry of the capital.
