Luzzatto's defense of Judaism and the Jews, under the title "A Treatise on the Position of the Hebrews," is masterly. It speaks eloquently for his practical, sober sense, for his love of truth, his attachment to Judaism, and his solid knowledge. He did not wish to dedicate it to any individual patron out of flattery, but to the friends of truth in general. He conjured these friends not to esteem the remnant of the ancient Hebrew nation, even if disfigured by sufferings, and saddened by long oppression, more lightly than a mutilated work of art by Phidias or Lysippus, since all men were agreed that this nation was once animated and led by the greatest of Masters. It is astonishing what thorough knowledge the rabbi had of the commerce of that time, and the influence upon it of the political position of European and neighboring Asiatic states. The object of his defense was primarily to disarm the ill-will of certain Venetian patricians against the Jews in that strictly governed state. The common people had little antipathy to the Jews; they lived to some extent on them. But among those who had a share in the government there were fanatical religious zealots and envious opponents, who advocated further restrictions, or even banishment. It did not suit them that the Venetian Jews, who, shut up in the Ghetto, possessed neither land nor the right to carry on a handicraft, competed with them in finance and trade. The commercial city of Venice, far surpassed by the new naval powers, Holland and England, which had gradually obtained control of the trade with the Levant, saw many of its great houses of business in splendid misery, while new Jewish capitalists stepped into their place, and seized the Levantine business. With artful turns and delicate hints, Luzzatto gave the politicians of Venice to understand that exhaustion was hastening the downfall of the republic. The prosperous cared only to keep what they had acquired and for enjoyment, and former Venetian commerce seemed to be falling into the hands of foreigners. Hence the Jews had become a blessing to the state. It was more advisable to leave its extensive trade, especially that of the East, to native Jews, and to protect them, than to see it diverted to neighboring towns, or to strangers, who formed a state within the state, were not always obedient to the laws, and gradually carried the ready money out of the country. Luzzatto calculated from statistics that the Jews contributed more than 250,000 ducats to the republic every year, that they gave bread to 4,000 workpeople, supplied home manufactures at a cheap rate, and obtained goods from distant countries. It was reserved for a rabbi to bring this political-economical consideration, of vital importance for the island republic, to the notice of wise councilors. Luzzatto also called attention to the important advantage which the capital of the Jews had recently been, when, during the pestilence and the dissolution of political government, the Jews had spontaneously offered money to the state to prevent embarrassment.
