Come, divine Plato! with your archetypal ideas, your androgynes, and your word; establish all these fine things in poetical prose, in your new republic, in which I no more aspire to have a house, than in the Salentum of Telemachus; but in lieu of becoming one of your citizens, I will send you an order to build your town with all the subtle manner of Descartes, all his globular and diffusive matter; and they shall be brought to you by Cyrano de Bergerac. Bayle, however, has exercised all the sagacity of his logic on these ancient fancies; but it is always by rendering them ridiculous that he instructs and entertains. O philosophers! Physical experiments, ably conducted, arts and handicraft--these are the true philosophy. My sage is the conductor of my windmill, which dexterously catches the wind, and receives my corn, deposits it in the hopper, and grinds it equally, for the nourishment of myself and family. My sage is he who, with his shuttle, covers my walls with pictures of linen or of silk, brilliant with the finest colors; or he who puts into my pocket a chronometer of silver or of gold. My sage is the investigator of natural history. We learn more from the single experiments of the Abbé Nollet than from all the philosophical works of antiquity. XENOPHON, AND THE RETREAT OF THE TEN THOUSAND. If Xenophon had no other merit than that of being the friend of the martyr Socrates, he would be interesting; but he was a warrior, philosopher, poet, historian, agriculturist, and amiable in society. There were many Greeks who united these qualities. But why had this free man a Greek company in the pay of the young Chosroes, named Cyrus by the Greeks? This Cyrus was the younger brother and subject of the emperor of Persia, Artaxerxes Mnemon, of whom it was said that he never forgot anything but injuries. Cyrus had already attempted to assassinate his brother, even in the temple in which the ceremony of his consecration took place--for the kings of Persia were the first who were consecrated. Artaxerxes had not only the clemency to pardon this villain, but he had the weakness to allow him the absolute government of a great part of Asia Minor, which he held from their father, and of which he at least deserved to be despoiled. As a return for such surprising mercy, as soon as he could excite his satrapy to revolt against his brother, Cyrus added this second crime to the first. He declared by a manifesto, "that he was more worthy of the throne of Persia than his brother, because he was a better magus, and drank more wine." I do not believe that these were the reasons which gained him the Greeks as allies. He took thirteen thousand into his pay, among whom was the young Xenophon, who was then only an adventurer. Each soldier had a daric a month for pay. The daric is equal to about a guinea or a louis d'or of our time, as the Chevalier de Jaucourt very well observes, and not ten francs, as Rollin says.
