Twelve years later, on a similar occasion, he uttered the following prophetic words:[93] "A genuinely free form of government makes a people free and upright, and its representatives are bound to be champions of liberty and progress. If Prussia, unfurling the banner of liberty and progress, will undertake to provide us with such a constitution, our self-confidence, energy, and trustfulness will return. Progress will be the fundamental principle of our lives, and out of our united efforts to advance it will grow a firm, indissoluble union. Now, then, Germans! Be resolved, all of you, to attain the same goal, and your will shall be a storm-wind scattering like chaff whatever is old and rotten. In your struggle for a free country, you will have as allies the army of mighty minds that have suffered for right and liberty in the past. Now you are split up into tribes and clans, held together only by the bond of language and a classic literature. You will grow into a great nation, if but all brother-tribes will join us. Then Germany, strongly secure in the heart of Europe, will be able to put an end to the quailing before attacks from the East or the West, and cry a halt to war. The empire, some one has said, means peace. Verily, with Prussia at its head, the German empire means peace." Such utterances are characteristic of Zunz, the politician. His best energies and efforts, however, were devoted to his researches. Science, he believed, would bring about amelioration of political conditions; science, he hoped, would preserve Judaism from the storms and calamities of his generation, for the fulfilment of its historical mission. Possessed by this idea, he wrote _Die Gottesdienstlichen Vorträge der Juden_ ("Jewish Homiletics," 1832), the basis of the future science of Judaism, the first clearing in the primeval forest of rabbinical writings, through which the pioneer led his followers with steady step and hand, as though walking on well trodden ground. Heinrich Heine, who appreciated Zunz at his full worth, justly reckoned this book "among the noteworthy productions of the higher criticism," and another reviewer with equal justice ranks it on a level with the great works of Böckh, Diez, Grimm, and others of that period, the golden age of philological research in Germany.
